V 1.0 INTRODUCTION

This Data Gathering Work Plan (Work Plan) is an addendum to the previous Remedial Investigation/Streamlined Risk Evaluation (RI/SRE), Field Sampling and Analysis Plan (FSAP), Work Plan, Quality Assurance Project Plan (QAPP), and Health and Safely Plan (HASP) prepared for work completed at the former Atlas "E" Missile Site 12 near Windsor, Colorado (Figure 1-1). The Work Plan has been prepared to allow Baker staff and subcontractors employ the appropriate procedures and protocols for collection and analysis of environmental samples and evaluation of the resulting data. The Work Plan also describes the management and staffing of this project as well as the project schedule.

Information concerning the operational history, waste characteristics and quantities, site description, and previous investigations summarized in the Work Plan is presented in detail in:

• Revised Draft Final Remedial Investigations/Streamlined Risk Evaluation, F. E. Warren AFB Atlas "E" Missile Site 12, Windsor, Colorado (Baker, June 2001).

• Final Site Investigation Report, F. E. Warren AFB Atlas "E" Missile Site 12, Windsor, Colorado (Baker, April 1998).

1.1 Purpose

The primary purpose of this work is to collect additional data prior to the initiation of a Feasibility Study based on the recommendations of the RI/SRE, the Colorado Department of Public Health and Environment (CDPHE), US Army Corps of Engineers-Omaha District (USAGE) and USEPA Region VIII. The Work Plan outlines the tasks that will be implemented to support the future development and evaluation of appropriate remedial alternatives for various areas of concern at Site 12. The Work Plan provides guidance for field activities by describing in detail the sampling and data collection methods to be used to implement the various field tasks. The Work Plan also helps to ensure that sampling and data collection activities are carried out in accordance with regulatory guidance and accepted professional practice so that data obtained during the field activities are of sufficient quantity and quality to evaluate the nature and magnitude of contamination in various media and determine which areas may require further action.

H:\_USACE_Omaha_20717\Windsonvorkplaiis\DataGallKring_FINAL\WorkPUii\DataGalhWP-12.doc 1-2 2.0 BACKGROUND AND SETTING

This section describes the history and site setting, previous investigations, recommendations and other actions conducted at Site 12.

2.1 Background Information

Site 12 is located in Weld County, Colorado, approximately three miles southeast of Windsor, Colorado and six miles west of Greeley, Colorado as shown on Figure 1-1. The current site map is presented as Figure 2-1. The original site consisted of 258.84 acres that was acquired by fee or condemnation in the early 1960s. Site 12 was one of nine Atlas "E" missile sites operated by the Air Force under the 549th Strategic Missile Squadron at F.E. Warren AFB, Cheyenne, Wyoming. Site 12 reportedly operated as an active missile site between the approximate years of 1960 and 1965. The area in the immediate vicinity of the site consists of farmland. Approximately six residences are within a one-mile radius of the site. The site currently is named the Weld County Missile Site Park. Weld County uses the facility buildings for storage of county vehicles, supplies, and files. A fence is constructed around the facility structures to restrict access. The area immediately surrounding the facility structures has been converted to a community park including camp sites, picnic tables, and a restroom structure and is open to the public.

A historical archive information review for Intercontinental Ballistic Missile (ICBM) facilities, which includes notes from interviews with the combat crew members, indicates that trichloroethene (TCE) was used at the Atlas "E" missile facilities. The crew members reported that the waste TCE and residual rocket fuel were dumped into the flame bucket (flame pit), which flowed to the wastewater drainage sump via a floor drain. Liquid collected in the drainage sump was subsequently discharged to the ground surface at the sump discharge headwall via sump pumps operated by a float control system. The disposition of the TCE, and potentially residual RP-1 rocket fuel, into the flame pit and subsequent discharge is believed to have contributed to groundwater contamination at the site. Other than this practice, there are no known waste disposal activities on record.

2-1 2.2 Previous Investigations

Previous investigations conducted at Site 12 included water sampling, closure of USTs, a Site Investigation (SI), a Remedial Investigation (RI), and a Streamlined Risk Evaluation (SRE). The results of each of these investigations are summarized in the following sections.

2.2.1 Water Sampling

A sample of the city water (connected to the site facilities in 1995) was collected by the USAGE on December 28, 1995. The sample was analyzed for volatile organic compounds (VOCs) by Environmental Protection Agency (EPA) Method 8010. The analytical results showed that the targeted parameters were below method quantitation limits.

2.2.2 UST Closures

In the Spring of 1994, E.T. Technologies, locate in Englewood, Colorado, was contracted by the USAGE - Omaha District to excavate and remove four underground storage tanks (USTs) at Site 12 including:

• One 300-gallon gasoline UST located adjacent to one supply well (Well No. 2) pumphouse (field investigation found that the tank was not present).

• One 275-gallon dirty lube oil UST located on west side of Launch Operations Building.

• One 16,000-gallon RP-1 rocket fuel (kerosene-type) UST located on west side of the Missile Launch and Service Building.

• One 300-gallon RP-1 catch tank located immediately south of the RP-1 UST.

Prior to excavation activities, one soil boring was advanced in the area of the 16,000-gallon RP-1 UST by Terracon Environmental, Inc. located in Ft. Collins, Colorado. The boring reportedly encountered free product at a depth of 28 feet, which corresponds to the bottom depth of the UST. Analytical results of a soil sample revealed 6,950 mg/kg (parts per million [ppm]) total petroleum hydrocarbons

H:\_USACE_Omaha_20717\Wmisorworkplans\DauGathering_FIN AlAWorfc PLanNDataGathWP-12.doc 2-2 (TPH) with a distillation range similar to diesel fuel or fuel oil. Excavation of the 16,000-gallon UST and subsequent soil sampling under the tank also found TPH concentrations up to 2,300 mg/kg at a depth of approximately 29 feet below grade. After the UST removal, E.T. Technologies excavated obvious contaminated soil under the tank. After the removal of 145 tons of contaminated soil, additional soil samples were collected from the base of each side of the deepest part of the excavation at a depth of 31.5 feet below grade. Samples from the north, south, and east walls were non-detect for benzene, toluene, ethylbenzene, xylenes (BTEX) and TPH. TPH was detected at 120 mg/kg in the sample collected from the western wall and BTEX was non-detect. Available documentation indicates that the USTs were removed in accordance with the State of Colorado's UST program.

The UST Closure Report dated May 19, 1994, also included closure documentation for both the former dirty lube oil and RP-1 catch USTs. Soil samples were collected from the areas under each of the USTs. The analytical results revealed the presence of 85 parts per million (ppm) oil and grease in one sample collected under the dirty lube oil UST while BTEX values were nondetect. Required analytical parameters were below detection in the soil samples collected from below the RP-1 catch tank. The CDPHE Storage Tank Program issued a No Further Action letter dated May 2,1995 for the three USTs removed from the site.

According to Mr. Harold Johnson, the former property caretaker (now deceased), the former fuel oil UST (fifth UST) was previously removed from west side of the Launch Operation Building (date unknown). Field observations of the area by Baker and USAGE representatives did not reveal the presence of the fill pipe and vent that are typically found associated with the former fuel oil UST. No direct correspondence relative to the UST removal has been uncovered. According to site drawings of similar Atlas sites, the USTs capacity was 16,000 gallons (9 ft. x 32 ft.).

2.2.3 Site Investigation

A SI was conducted in 1996 to investigate the extent and magnitude of potential contamination within the various environmental media in response to former DoD operations. The SI field program included the advancement of 17 soil borings and the collection of 52 subsurface soil samples, collection of two open borehole groundwater samples, installation of eight groundwater monitoring wells and the collection of eight groundwater samples, collection of one water sample from two of the

H:\_USACE_Omaha_20717\WiiKlsorwori(plaiis\DataGathning_FINAl.\WorkPlan\DataGathWP-]2doc 2-3 three on-site supply wells, and collection of water samples from the flame pit and the liquid oxygen sump.

Note that surface soil samples were not collected during the SI. Subsequently, surface soil samples were collected during the RI. Analytical results were screened against Region 3 Risk-Based Concentrations (RBCs).

Subsurface Soil

Fifty-two subsurface soil samples were collected from the 17 soil borings advanced throughout the site. Arsenic was detected at concentrations in most samples in exceedence of the EPA Region III Residential Risk-Based Concentration (RBC), and in approximately 25 percent of the samples in exceedence of the Industrial RBC.

TPH-DRO (and no SVOCs) was detected in the subsurface soil sample collected from soil boring SB- 5 at a level of 260 mg/kg. Soil boring SB-5 is located in the area of the former RP-1 UST. The soil sample was collected from a depth of 32 feet below grade, which is the approximate depth of the remedial excavation after removal of the UST. The Colorado Department of Labor and Employment Oil Inspection Section (OIS) soil cleanup guidelines for a Remedial Action Category (RAC) III designation are 100 mg/kg BTEX and 500 mg/kg TPH-DRO. The soil sample in which the TPH- DRO was detected was non-detect for BTEX compounds. The detected TPH-DRO level of 260 mg/kg is below the cleanup standard of 500 mg/kg.

Groundwater

TCE, cis 1,2-dichloroethene (cis 1,2-DCE), vinyl chloride, chloroform, bis (2-ethylhexyl)phthalate, antimony, beryllium, iron, manganese, and selenium were detected above the groundwater SI comparison criteria in select Fox Hills Sandstone Formation monitoring well samples. The SI comparison criteria used for evaluation of the groundwater analytical data included the CDPHE Basic Standards for Groundwater (CBSGs), the Federal Maximum Contaminant Levels (MCLs), and EPA Region III RBCs for tap water.

H:\_USACE_Omaha_20717\Wmdsonvorkplaro\DataGathering_FINALWorit PUn\DaIaGathWP-12.doc 2-4 TCE was detected in excess of the CBSG in the groundwater samples collected from monitoring wells MW-1, MW-4, MW-5, MW-7, and MW-8. These monitoring wells are located in close proximity to the Missile Launch and Service Building, wastewater drainage sump, flame pit, and discharge headwall. Based on photoionization detector (PID) readings of soil cores and the groundwater analytical results, the wastewater drainage sump is identified as the primary contaminant source area. Dissolved phase contaminant distribution in the area of the wastewater drainage sump is attributed to groundwater mounding under the Missile Launch and Service Building and radial groundwater flow outward from the structure.

Cis 1,2-DCE was detected in the majority of monitoring well groundwater samples that exhibited detectable levels of TCE, excluding MW-1. The presence of cis 1,2-DCE is considered to represent the primary biodegradation product of TCE. The highest level of cis 1,2-DCE (340 |J.g/L) was detected in the groundwater sample collected from monitoring well MW-5, which was the only monitoring well sample to exhibit cis 1,2-DCE at a level in excess of the CBSG (70 jug/L). Cis 1,2- DCE also was detected in the groundwater samples collected from monitoring wells MW-4, MW-7, and MW-8 at concentrations ranging from 1.2 ng/L to 40 p.g/L.

Vinyl chloride was detected in the groundwater sample (9.4 ug/L) and duplicate sample (9 |u.g/L) collected from monitoring well MW-8 at levels in excess of the CBSG (2 ug/L). Vinyl chloride is considered to represent a degradation product of cis 1,2-DCE (note: cis 1,2-DCE is the primary degradation product of TCE under anaerobic conditions. Trans 1,2-DCE, another degradation product of TCE, was not detected in the groundwater sample collected from monitoring well MW-8). Vinyl chloride was not detected at levels above the method detection limits in the other seven monitoring well samples.

A trace level of chloroform was detected in the groundwater sample collected from monitoring well MW-2 which was below the CBSG. Chloroform was detected at a concentration of 59 J u,g/L in the open borehole sample collected from soil boring SB-7, which exceeds the CBSG.

Low levels of aromatic hydrocarbons (BTEX) were detected in the groundwater samples collected from select monitoring wells. The levels were well below the CBSGs.

H\_USACE_Omaha_20717\Windsorworkplans\DataGathering_FINAL\WorkPlan\DauGathWP-12.doc 2-5 Information collected during the SI regarding groundwater quality was supplemented through the collection of groundwater samples from open boreholes. Groundwater samples were collected from the open boreholes of soil borings SB-6 and SB7, which were advanced in the area of the wastewater drainage sump and flame pit, and analyzed for VOCs.

A low level of toluene (10 u,g/L) was detected in groundwater from soil boring SB-6. Soil boring SB-6 was advanced to a depth of 260 feet. Drilling included the installation of a six-inch exterior casing during soil core advancement to a depth of 195 feet. The casing is anticipated to have effectively sealed the upper portion of the stratigraphic profile and saturated zone at approximately 40- 60 feet below grade where contamination was detected. The groundwater sampled from the borehole is anticipated to represent groundwater quality at depths below 200 feet. The analytical results of the groundwater sample collected from borehole SB-6 were used qualitatively to delineate the vertical extent of TCE contamination in the immediate source area of the wastewater drainage sump.

Soil boring SB-7 was advanced through the concrete pad support structure immediately south of the flame pit. Based on field observations, the depth to the water table was approximately 50 feet below grade. The total depth of the soil boring extended to 71.5 feet below grade. The open borehole sample was collected from the standing water surface in the borehole (i.e., 50 feet) at the completion of soil boring advancement. An elevated level of TCE (4,000 (ig/L) was detected in the sample, which is in excess of the CBSG. This level represents the highest level of TCE detected during the SI. Cis 1,2-DCE (190 ng/L) and chloroform (59 |ag/L) were detected in the open borehole sample at concentrations that exceeded the CBSGs.

2.2.4 Remedial Investigation

The RI was performed at the site in response to detected levels of TCE in five of eight monitoring wells installed on the property during the SI.

H:VUSACE_Omaha_20717\Windsonvoritpliins\DataGathcring_FIN AL\WorkPIan\DataGathWP-12.doc 2-6 The objectives of the RI included the following:

• Confirm the detectable contamination levels within the study area

• Assess the type, extent, and degree of contamination within the study area

• Assess the potential for contaminant migration into, and through the surrounding environs

• Assess public health and environmental risks of contaminants relative to the applicable regulatory standards

• Identify further investigations and/or response actions at the site, as necessary

Investigative activities were performed at the site during the period May through July, 1999. The RI field program included the advancement of soil borings, collection of subsurface soil samples, installation and sampling of groundwater monitoring wells, collection of on-site supply well samples, collection of one surface water sample, collection of indoor air samples, and collection of surface soil samples. Analytical results of the RI were screened against Region 3 RBCs; the SRE used Region 9 Preliminary Remediation Goals (PRGs).

2.2.4.1 Surface Soil Sampling

A total of 21 surface soil samples were collected from the site area. Eleven surface soil samples (SS01 through SS10 and SS21) were collected for VOCs, PP Metals, and PCB analyses from within the site security fence to confirm and delineate potential surface soil contaminants. Three of the 11 on-site samples (SS04, SS05, and SS06), collected in the vicinity of the wastewater drainage sump headwall, also were analyzed for TPH-Diesel Range Organics (DRO). Ten background surface soil samples (SS11 through SS20) were collected at approximate equal intervals along the perimeter of the property boundary and analyzed for PP Metals. The background samples were collected from areas that were not impacted by past DoD operations, based on available information and field observations.

H \_USACE_Omaha_207I7\WindsonvorkpUns\DauGathering_FrNAL\Work PUn\DataGalhWP-12.doc 2-7 2.2.4.2 Subsurface Investigation

The objectives of the subsurface investigation were to characterize the off-site subsurface stratigraphic profile and install groundwater monitoring wells to better define the extent and magnitude of groundwater contamination. Fourteen soil borings were advanced to depths ranging from 55 to 148 feet below grade. Each of the soil borings were converted to groundwater monitoring wells.

Seven shallow (Fox Hills Sandstone Formation) and seven deep (Pierre Shale Transition Zone) groundwater monitoring wells were installed at the site. Groundwater samples were collected from 22 monitoring wells, including eight Fox Hills Sandstone Formation wells installed during the SI, and analyzed for VOCs (including speciation for "cis" and "trans" isomers), PP Metals (dissolved), and natural attenuation parameters (including alkalinity, pH, temperature, dissolved oxygen, redox potential and ferrous iron by field measurements/test kits and sulfate, methane, ethane/ethene, total organic carbon, chloride, and nitrate by laboratory analysis).

2.2.4.3 On-Site Supply Well Sampling

Groundwater samples were collected for VOCs, PP Metals (dissolved), and natural attenuation parameters analyses from the three on-site water supply wells during the Site 12 RI.

2.2.4.4 Sump Sampling

Water samples were collected for VOC analysis from the wastewater drainage sump and sub-drain sump (located at southeast corner of the Launch Operations Building).

2.2.4.5 Surface Water Sampling

One surface water sample was collected from the Cache Le Poudre River and analyzed for VOCs. This surface water sample was proposed to be collected from the stock pond located in the valley north of the site; however, the stock pond was dry throughout the duration of the Site 12 field investigation.

H:\_USACE_Oinaha_20717\Windsorworkplans\DataGathering_FINAL\WorkPlan\DalaGathWP-12doc 2-8 2.2.4.6 Indoor Air Quality Sampling

Indoor Air Quality (IAQ) sampling was conducted, to collect data for assessing human health risks associated with the air pathway/exposure route. Six IAQ samples were collected over a 24 hour period using evacuated SUMMA canisters within the Launch Operation and Missile Launch and Service Buildings. The samples were analyzed for TCE, vinyl chloride, 1,1 -DCE, and cis 1,2-DCE according to EPA Method TO-14.

2.2.4.7 Site Hydrogeologic Conditions

The stratigraphic profile encountered under the site consists of the lower Fox Hills Sandstone Formation (interlayered fine-grained sandstone and siltstone exhibiting multiple color variations of brown, grey, yellow and orange) overlying medium to dark grey siltstone, silty sandstone, and shale of the Pierre Shale Transition Zone. The Fox Hills Sandstone Formation conformably overlies the Pierre Shale Formation and the contact between the two units is transitional and often arbitrarily picked, according to geologic reference material. For this RI the contact between the Fox Hills Sandstone Formation and Pierre Shale Transition Zone was identified at the first significant color change from multicolored (brown, grey, yellow, and orange) to predominantly dark grey.

Due to the drilling methods employed during the RI, geologic details for the Pierre Shale Transition Zone were not attainable. The geologic interpretations that follow were evaluated only by the drill cuttings and review of the grainsize distribution curves. Three general stratigraphic "layers" were encountered within the Pierre Shale Transition Zone including:

• Siltstone with thinly interbedded fine-grained sandstone with minor shale, light to dark grey, approximately 10 to 20 feet thick.

• Shale with interbedded siltstone and minor fine-grained sandstone, light to dark grey, approximately 20 to 30 feet thick.

• Thinly interbedded siltstone and shale with minor interlayers of fine-grained sandstone, medium to dark grey, extending to the depth of the Pierre Shale Transition Zone monitoring wells.

H:\_USACE_Omaha_20717\Windsonvorkplans\DataGathering_nNAL\Work Plan\DataGathWP-12.doc 2-9 The water table in the Fox Hills Sandstone Formation was measured at elevations ranging from 4,880 to 4,926 feet above mean sea level (MSL). The aquifer is interpreted to be under unconfmed conditions. The contact of the Fox Hills Sandstone Formation and Pierre Shale Transition Zone was interpreted to occur at an elevation ranging from approximately 4,879 to 4,907 feet MSL, which indicates a saturated depth within the Fox Hills Sandstone Formation ranging from less than one foot to 26 feet.

The Fox Hills Sandstone Formation potentiometric surface is subplanar in the northern portion of the property with a general northward groundwater flow direction. The water table surface is coincident with the contact surface of the Fox Hills Sandstone Formation and Pierre Shale Transition Zone. The water table surface underlying the Missile Launch and Service Building (southern portion of the property) shows mounding and radial flow outward in all directions. The average gradient of the Fox Hills Sandstone Formation potentiometric surface is 0.054. This gradient generally correlates to the gradient calculated on-site for the Fox Hills Sandstone Formation during the SI (i.e., 0.06).

The Pierre Shale Transition Zone potentiometric surface shows a near planar water table surface across the site. The groundwater flow direction in the Pierre Shale Transition Zone is oriented in an northeastward direction. The average gradient of the Pierre Shale Transition Zone potentiometric surface is calculated as 0.02.

Examination of the groundwater elevations in each of the seven nested well pairs indicates a downward potential gradient. The estimated vertical gradients ranged between 0.625 and 0.723.

The Fox Hills Sandstone Formation water-bearing zone is interpreted to be unconfined. The Pierre Shale Transition Zone water-bearing zone is interpreted to be semi-confined. The siltstone and shale layers act as a leaky aquitard between the two water-bearing zones. The bedrock between the bottom of the Fox Hills Sandstone Formation water-bearing zone and the first water-bearing zone of the Pierre Shale Transition Zone appears to be unsaturated. It is likely that the shallow water table, recorded in area wells and on-site monitoring wells, is unconfined and potentially perched.

The depth to water was measured in the on-site supply Well No. 1 at approximately 198 feet below grade. The depth of Well No. 1 is approximately 625 feet below grade. The depth to the water table in the local supply wells ranged from 7 to 86 feet below grade with well depths ranging from 23 to 800 feet below grade. This pattern indicates that well yield in the deep on-site wells is from deeper water-bearing zones within the Pierre Shale Formation under semi-confined conditions.

2.2.4.8.1 Surface Soil Sampling Results

The RI comparison criteria used for evaluation of the surface soil analytical data included the EPA Region III Residential Soil RBCs (April 2000 version). The RBCs were developed by the USEPA, Region III as benchmark concentrations for evaluating site investigation data. RBCs are not intended as stand-alone decision-making tools, but as a screening tool to be used in conjunction with other information to help in the evaluation of detected compounds and/or analytes in site-related media. Background data are also used in the evaluation of site-specific data.

VOCs and PCBs were not detected at or above the respective method detection limits in the 11 on-site surface soil samples. TPH-DRO was detected in one (SS06) of the three samples analyzed at a concentration of 8.2 J mg/kg. This value is below the method detection limit (13 mg/kg) and reported with a "J" qualifier (i.e., the value is an estimated quantity).

Several of the PP Metals constituents were detected in at least one sample above background levels. However, with the exception of arsenic in each of the samples, none of the reported levels exceed EPA Region III Residential Soil RBCs. Arsenic at naturally occurring concentrations, was detected in each of the ten background surface soil samples at a concentrations above the RBC (0.43 mg/kg). Based on the low levels and distribution of arsenic across the site, it is difficult to suggest that the former site operations are responsible for this constituent on-site.

2.2.4.8.2 Monitoring Well Sampling Results

Groundwater samples were collected from 22 monitoring wells (i.e., 14 new and eight existing wells) and three on-site water supply wells. The RI comparison criteria used for evaluation of the groundwater analytical data included the CDPHE CBSGs, the Federal MCLs, and EPA Region III RBCs for tap water.

HA_USACE_Omata_20717\Windsorworkplans\DauGathering_FINAL\Woric PlamDataGathWP-12.doc 2-11 Volatile Organic Compounds - Fox Hills Sandstone Formation (Shallow)

TCE was detected in 12 of the 15 Fox Hills Sandstone Formation groundwater samples. The CBSG and Federal MCL for TCE (both 5 p.g/L) was exceeded in samples collected from eight monitoring wells.

Elevated dissolved-phase TCE concentrations were detected under the eastern central portion of the facility property (i.e., MW-5 and MW-8). The source for the elevated dissolved-phase TCE is suspected to be the Missile Launch and Service Building (i.e., wastewater drainage sump). Sources of the lower levels of TCE present under the site is suspected to be the wastewater drainage sump discharge headwall, the drainage ditch, and the retention pond.

The highest levels of dissolved phase TCE were detected in the groundwater samples collected from monitoring well MW-5 (1,900 ng/L) and MW-12 (1,500 jig/L). These areas are located on opposite sides of the Missile Launch and Service Building and flame pit. TCE was detected in MW-8, located approximately 12 feet southwest of the wastewater sump, at 410 ug/L. The variability in the TCE concentrations in the immediate vicinity of the Missile Launch and Service Building indicates spacial distribution may be related to stratigraphy, additional contaminant source areas (sub-drain system, floor drains, liquid oxygen sump), fill material type and extent, and/or sample collection techniques.

The analytical results of the groundwater samples collected from downgradient monitoring wells MW-2 and MW-11 did not exhibit VOC concentrations above method detection limits (1.0 |J.g/L) and downgradient wells MW-3 and MW-6 exhibited estimated TCE concentrations (detected below the method detection limits) of 0.78 (j.g/L and 0.37 ug/L, respectively. Based on the potentiometric surface map, projected groundwater flow direction, and TCE isoconcentration map, delineation of the dissolved phase TCE plume in the Fox Hills Sandstone Formation water-bearing zone is complete north of the site.

Monitoring well MW-1 is located south (downgradient) of the facility and the groundwater sample exhibited 25 |J.g/L TCE. Monitoring well MW-4 is located east (downgradient) of the facility and the groundwater sample exhibited 99 \ig/L TCE. Although these levels exceed the CBSG, the well locations are interpreted to approximate the lateral extent of dissolved phase TCE-impacted groundwater south and east of the Missile Launch and Service Building. VOC-impacted groundwater may be migrating off-site toward the east. The eastern property line is bound by a steep tributary wall. RI investigations did not include this area due to the limited access.

HA_USACE_Oraaha_20717\Windsorworkplans\DataGMlKring_FINAL\WorkPlan\DataGathWP-12.doc 2-12 The analytical results of the groundwater samples collected from monitoring wells MW-7, MW-9, and MW-13 exhibited 210 (ig/L, 120 |ig/L , and 630 ug/L TCE, respectively. These wells are located downgradient, west and southwest, of the Missile Launch and Service Building near the wastewater drainage sump discharge headwall and in the vicinity of the reported retention pond. These detections indicate that the lateral extent of dissolved phase TCE is not delineated west and southwest of the Missile Launch and Service Building. The location of the wells and their associated concentrations indicate that VOCs may have originated from the lateral migration of contaminated groundwater from the Missile Launch and Service Building area and/or the vertical percolation of contaminated water from the wastewater drainage sump discharge headwall or retention pond.

The site groundwater analytical results indicate that dissolved-phase TCE in the groundwater has extended west and southwest, beyond the western property boundary. The lateral extent of the TCE contaminant plume shows the likelihood that the contaminant plume originates from the wastewater drainage sump, wastewater drainage sump headwall, and retention pond.

Cis 1,2-DCE was detected in seven of the 15 Fox Hills Sandstone Formation groundwater samples ranging between 0.2 U (ig/L and 360 |J.g/L. Cis 1,2-DCE was detected above the CBSG and Federal MCL (both 70 (ig/L) in the groundwater samples collected from monitoring wells MW-5 (360 ug/L) and MW-12 (110 ug/L). The presence of cis 1,2-DCE is considered to represent the primary breakdown product of TCE; MW-5 and MW-12 exhibited the highest TCE concentrations of 1,900 Hg/L and 1,500 pg/L, respectively. Vinyl chloride, which is another degradation product of cis 1,2- DCE, was not detected in the groundwater samples. Cis 1,2-DCE was not detected in the seven Pierre Shale Transition Zone groundwater samples.

The RBCs for 1,1 -DCE (0.04 |u.g/L) and chloroform (0.15 ug/L) were exceeded in one and two of the Fox Hills Sandstone Formation groundwater samples, respectively. 1,1 -DCE was reported for MW-7 at 0.18J ng/L and chloroform was reported for MW-7 at 0.43 J ug/L and MW-12 at 0.42J ng/L. Each of these detections are denoted as "J" values. None of the results exceed the EPA or CDPHE MCLs for 1,1-DCE (7.0 ug/L) or chloroform (100 ug/L). Chloroform is commonly used in the laboratory and may represent sample contamination during analysis.

H:\_USACE_Omaha_20717\Windsorworkplans\DataGathering_FINAL\WorkPlan\DaIaGathWP-12doc 2-13 Low levels of acetone, benzene, and toluene were detected in groundwater samples collected from a limited number of the Fox Hills Sandstone Formation groundwater samples. Acetone was detected in MW-3 at 1.7 ug/L. Toluene was detected in six samples ranging between 0.35J ug/L and 4.1 ug/L; three of the results are denoted as "J" values. Benzene was detected in MW-3 (0.25 J ug/L), MW-7 (0.23J ug/L), and MW-10 (0.33J ug/L). Each of the benzene detections are denoted as "J" values. None of the values exceed the comparison criteria for the site. Acetone is commonly used in the laboratory and may represent sample contamination during analysis.

Volatile Organic Compounds - Pierre Shale Transition Zone (Deep)

Detectable levels of TCE was reported for three of the seven Pierre Shale Transition Zone groundwater samples ranging between 0.3 J ug/L and 1.0 ug/L. Two of the three detections are denoted as "J" values. None of the values exceed the TCE comparison criteria for the site. Cis 1,2- DCE, considered to represent the primary breakdown product of TCE, was not detected in the Pierre Shale Transition Zone groundwater samples.

The RBC for chloroform (0.15 ug/L) was exceeded in seven the Pierre Shale Transition Zone groundwater samples ranging between 0.29J ug/L and 2.7 ug/L. Two of the seven detections are denoted as "J" values. None of the results exceed the EPA or CDPHE MCL of 100 ug/L. As previously stated, chloroform is commonly used in the laboratory and may represent sample contamination during analysis.

Low levels of acetone, methylene chloride, toluene, and total xylenes were detected in at least one of the Pierre Shale Transition Zone groundwater samples. Acetone was detected in MW-1 B at 1.4 ug/L and MW-9B at 1.9 ug/L. Methylene chloride was detected at estimated concentrations (denoted with a "J") in MW-2B at 0.17J ug/L and MW-9B at 0.32J ug/L. Toluene was detected at or above the method detection limit (1.0 ug/L) in MW-9B at 1.6 ug/L and MW-15B at 9.4 ug/L. Toluene also was detected at estimated concentrations in four samples ranging between 0.48J ug/L and 0.95J ug/L. Total xylenes was detected in MW-9B at an estimated concentration of 0.34J ug/L. Acetone and methylene chloride are commonly used in the laboratory and may represent sample contamination during analysis. None of the values exceed the comparison criteria for the site.

H:\_USACE_Omaha_20717\WindMrworkplans\DataGathering_FINAL\Work PtaiADataGathWP-12 doc 2-14 Priority Pollutant Metals

Only a limited number of PP Metals (arsenic, manganese, and selenium) exceeded groundwater standards or health-based criteria. Arsenic was detected at levels above the EPA Region HI Tap Water RBC (0.045 ng/L) in the Pierre Shale Transition Zone monitoring wells MW-1 IB (2. IB ng/L) and MW-1 5B (2.8B |ig/L). The results were flagged with a "B" qualifier (i.e., estimated value) indicating that the results were less than the reporting limit and greater than or equal to the method detection limit. Arsenic was not detected in the Fox Hills Sandstone Formation monitoring wells.

Manganese was detected at levels exceeding the CBSG Secondary Drinking Water Standard (50 (ig/L) in 8 of the 22 groundwater samples ranging between 76.9 (ig/L and 45 1 (ig/L. Manganese was reported in the Fox Hills Sandstone Formation monitoring wells MW-2 (233 (ig/L), MW-6 (433 ug/L), MW-10 (76.9 jag/L), MW-1 1 (92.8 ng/L), and MW-1 5 (119 ug/L) and in the Pierre Shale Transition Zone monitoring wells MW-2B (140 ^g/L), MW-6B (451 ^g/L), and MW-1 OB (84.1

Selenium was detected at levels above the CBSG (50 p.g/L) in 12 of the 22 groundwater samples ranging between 51.6 )iig/L and 320 )u.g/L. Selenium was reported in the Fox Hills Sandstone Formation monitoring wells MW-1 (158 |ag/L), MW-3 (126 (ig/L), MW-4 (178 jig/L), MW-5 (57.5 Mg/L), MW-6 (51 .6 ng/L), MW-9 (66.8 ng/L), MW-10 (168 ug/L), MW-1 1, (82.9 pg/L) MW-12 (204 Ug/L), MW-1 3 (1 07 |ig/L), MW-1 4 (289 jig/L) and MW-1 5 (320 ng/L). Selenium was not detected in the Pierre Shale Transition Zone monitoring wells at levels above the reporting limit and greater than or equal to the method detection limit.

The presence of arsenic, manganese, and selenium is believed to be naturally occurring and not related to past site operations. No other priority pollutant metals exceeded the RJ comparison criteria.

2.2.4.8.3 On-Site Supply Well Results

Groundwater samples were collected for VOC analysis from the three on-site supply wells at the onset of the field investigation. The wells again sampled during the groundwater sampling program, for VOC, PP Metals, and natural attenuation parameters.

H \_USACE_Omaha_2071 7\Wind»nvorkplans\D3taGathering_FINAL\Worfc PIan\DataGathWP- 1 2 doc 2-15 VOCs were not detected at or above the method detection limits in the three on-site supply wells during the May 19,1999 sampling event with the exception of acetone. Acetone was detected at 4.2 (j.g/L in Well # 1. VOCs were not detected at or above the method detection limits in the three on-site supply wells during the July 23,1999 sampling event.

Several of the PP Metals constituents were detected in at least one supply well sample. However, with the exception of zinc in Well #2, the results were flagged with a "B" qualifier (i.e., estimated value), indicating that the results were less than the reporting limit and greater than or equal to the method detection limit. None of the reported levels exceed the RI comparison criteria.

2.2.4.8.4 Sump Sampling Results

Water samples were collected for VOC analysis from the wastewater drainage sump and sub-drain sump (located at southeast corner of the Launch Operations Building. The wastewater drainage sump sample (SW01) was collected from the sump pump spigot during operation of the pump. The sub- drain sump sample (SW03) was collected from standing water using disposable PVC bailer.

TCE, cis-l,2-DCE, vinyl chloride, and 1,1-DCE were detected in the wastewater drainage sump sample at 15 |ig/L, 8 M-g/L, 2.1 |ig/L, and 0.39J |ig/L, respectively. VOCs were not detected in the sub-drain sump sample.

2.2.4.8.5 Surface Water Results

One surface water sample (SW02) was collected for VOC analysis from the Cache La Poudre River. Acetone (3.2 |j.g/L) was the only VOC detected in the surface water sample. Acetone is commonly used in the laboratory and may represent sample contamination during analysis.

2.2.4.8.6 Indoor Air Quality Results

Six IAQ samples were collected and analyzed for TCE, vinyl chloride, 1,1-DCE, chloroform, and cis 1,2-DCE in accordance with EPA Method TO-14.

H:\_USACE_Otnaha_20717\Windsorworkplans\DataGMhering_FINAL\WorkPlan\DataGathWP-12.doc 2-16 The following results were obtained:

• The concentrations of the chemicals of concern in the background sample were reported to be below the detection limits.

• The concentrations of the chemicals of concern in the indoor air samples were below the limits of detection.

2.2.4.9 RI Conclusions

• Surface soil at Site 12 does not appear to be adversely impacted by past site operations.

• Shallow, Fox Hills Sandstone Formation groundwater under the site is impacted by former site operations due to the presence of VOCs (TCE , cis 1,2-DCE, 1,1-DCE, and trace concentrations of benzene and toluene).

• The extent of shallow, VOC-impacted groundwater extends west and southwest, beyond the southwestern property boundary.

• Shallow, VOC-impacted groundwater may be migrating off-site toward the east; the eastern property line is bound by a steep tributary wall.

• The horizontal extent of shallow, VOC-impacted groundwater is unknown.

• Groundwater within the Pierre Shale Transition Zone is impacted by dissolved phase TCE. Trace concentrations of TCE was reported for three of the seven Pierre Shale Transition Zone groundwater samples ranging between 0.3 J jig/L and 1.0 |Jg/L. Note that two of the three detections are denoted as "J" values (i.e., estimated) and 1.0 ^ig/L is the detection limit for TCE . None of the values exceed the RI comparison criteria for the site.

• Several inorganics exceed the RI comparison criteria: manganese, selenium and arsenic. The presence of these constituents are considered to be naturally occurring and not related to past site operations. H:\_USACE_Omaha_20717\Windsorworkplans\DataGathering_FINAL\Wotk PlanVDataGalhWP-12.doc 2-17 • The three on-site supply wells have not been impacted by past site operations.

• TCE, cis 1,2-DCE, vinyl chloride, and 1,1-DCE were detected in the wastewater drainage sump sample at 15 ug/L, 8 ug/L, 2.1 ug/L, and 0.39J ug/L, respectively. VOCs were not detected in the sub-drain sump sample.

• Acetone was detected in the surface water sample collected from the Cache La Poudre River. Acetone is commonly used in the laboratory and may represent sample contamination during analysis.

• VOCs were not detected in the indoor air samples, suggesting that former waste disposal practices have not impacted IAQ.

• A total of 20 monitoring wells were assessed to determine if the biodegradation of TCE was occurring. Based on the AFCEE screening scores, and a comparison of geochemical indicators between background and plume monitoring wells it can be concluded that inadequate evidence exists for the biodegradation of TCE in the groundwater of the Fox Hills Sandstone Formation. Inadequate to limited evidence for biodegradation of TCE exists in the groundwater of the Pierre Shale Transition Zone.

2.2.5 Streamlined Risk Evaluation

2.2.5.1 Human Health SRE Conclusions

Results of the human health evaluation indicated potential carcinogenic risks and noncarcinogenic adverse health effects to the adult and child future residential receptors for the Reasonable Maximum Exposure (RME) scenario. The presence of TCE and vinyl chloride in the untreated shallow groundwater contributed to the unacceptable risk, while antimony was the primary contributor to the elevated noncarcinogenic adverse health effect values for the future residents. Also, the lead Integrated Exposure Uptake Biokinetic Lead Model (IEUBK) model indicated that the maximum detected concentration for lead in shallow groundwater would result in blood lead levels (in young children) that would exceed USEPA acceptable levels. Currently, carcinogenic risks and adverse health hazards calculated for the current adult resident, current adult and child recreational users, and future construction workers were within USEPA's acceptable criteria.

H\_USACE_Omaha_20717\Windsorworicplans\DiitaGatheriiig_FINAL\WorkPUn\DauGathWP-12.doc 2-18 Antimony and lead in shallow groundwater were detected in samples collected during the 1996 SI. The maximum concentration for antimony was the primary contributor to the elevated Hazard Index (HI) values for the future residents, while the maximum concentration for lead triggered unacceptable blood lead levels when using the lead IEUBK model. As previously mentioned, antimony and lead were detected in the eight samples collected during the 1996 SI. Antimony and lead were not detected in any of the 15 groundwater samples collected during the 1999 RI (including the eight existing wells that were resampled). The 1999 RI shallow groundwater data, which includes resampling of the monitoring wells sampled in 1996, indicate that it is not likely that antimony and lead in shallow groundwater will cause adverse health effects to future receptors. However, in order to maintain a conservative approach, the HI values calculated using the maximum antimony concentration and the results of the IEUBK model using the maximum lead concentration are presented in this human health SRE.

2.2.5.2 Environmental SRE Conclusions

To evaluate the potential for adverse ecological effects caused by contaminants at Site 12, hazard quotients calculated during both conservative and less conservative risk evaluations were considered in combination with data regarding site history, compound prevalence, and the magnitude of potential risks. Potential risks to current and future aquatic receptors at or near Site 12 are low. There is no unacceptable risk to aquatic receptors from current off-site surface water conditions. Antimony, chromium, copper, and selenium in groundwater from the shallow Fox Hills Sandstone Formation could pose potential risks to future aquatic receptors if this groundwater discharged to a surface water body without dilution or natural attenuation. There is no evidence that such groundwater discharge is occurring. Potential risks to terrestrial receptors from surface soils were driven by inorganics. Plants, earthworms, microorganisms, and microbial processes are at potential risk from chromium. Plants are also potentially at risk from zinc. The red fox is at potential risk from antimony, the cottontail rabbit is at potential risk from arsenic, and the American robin is at potential risk from thallium and zinc. Potential risks contributed by antimony, chromium, and thallium on site were similar to potential risks calculated for background soils. Potential risks driven by arsenic were approximately two times greater on site, while potential risks driven by zinc were approximately five times greater on site relative to background conditions. None of the inorganics detected in the groundwater or surface soils have previously been associated with historical site activities. It should be noted that the risk assessment techniques used indicate a potential risk and not an actual risk to the flora and fauna exposed.

H:\_USACE_Omaha_20717\Windsorworkplans\0alaGathering_FINAL\WorkPliin\DataGathWP-12doc 2-19 3.0 FIELD SAMPLING AND ANALYSIS PLAN

The data gathering activities objectives are to further evaluate the absence or presence of a former fuel oil UST and associated contamination, obtain current information about the wastewater sump drainage, and determine the possible interconnection between the wastewater drainage sump, the flame pit and the perched groundwater. This information, along with previous investigation results will support the future development and evaluation of appropriate remedial alternatives for various areas of concern at Site 12.

The section serves as the Field Sampling and Analysis Plan (FSAP) for implementation of additional field activities. The FSAP describes the location and frequency of environmental samples that are to be collected during implementation of the field activities. Support activities, sampling locations, sample matrices and constituents to be analyzed are discussed within this section. Investigation procedures and sample handling and analytical requirements are presented in Sections 5.0 and 6.0 of this FSAP, respectively.

The field program for Site 12 will include the following activities:

• Mobilization/demobilization • Water Well Location Confirmation and Well Sampling • Wastewater Sump Drainage Verification • Potentiometric Surface Study • UST Subsurface Soil Sampling • Investigation Derived Waste Handling

3.1 Mobilization/Demobilization

Mobilization and demobilization consist of office preparation for organizing support operations pertaining to the field investigation. Office activities primarily include well inventory mapping and wastewater sump drainage verification. In addition, equipment procurement, travel arrangements to and from the site, and determining and organizing support operations. Demobilization consists of removal of equipment and personnel from the site.

H \_USACE_Omaha_2u7l7\WindsoTOOrkplans\DalaGalhenng FINAL\Work PlarADataGathWP-12 doc 3-1 3.1.1 Well Inventory Mapping

Baker coordinated with the Colorado State Engineers Office (CSEO) to obtain water well information near the site. The data was incorporated to expand the Colorado Well Inventory list and Well Records Map of the RI/SRE. Figure 3-1 was developed to document the wells within a 2-mile radius of the site. The well information also is provided in tabular form as Attachment A.

3.1.2 Wastewater Sump Drainage Verification

Baker will verify the installation and operation of the wastewater discharge sump pump by Weld County personnel. Currently, Weld County personnel discharge the water onto the ground surface. Baker will review mapping of site discharge and discuss with Weld County personnel typical site conditions and those during rain events and spring thaw. As a follow-up to the telephone conversation with Weld County personnel familiar with the operations of the facility, a Baker representative will field verify the information.

3.2 Water Well Location Confirmation and Well Sampling

The Baker field team will attempt to field verify the locations of nearby CSEO-documented wells. Field verification will include driving to a listed well and visually verifying a residence is present at the location from the road. Note that wells located north of the Cache La Poudre River will not be field verified. Well owners will not be contacted or properties trespassed unless requested by USAGE prior to the field work activities. Residences not identified in the well inventory search, but discovered during the field verification and thought to have a well will be identified.

Three identified wells will be sampled and analyzed for VOCs, if access is granted and the wells accessible: the Jess Anderson (Section 34), Robert Anderson (off Route 257), and Kodak (Section 35) wells. In addition, an unmarked structure in Section 3, near the 4,800-foot contour label will be investigated.

II \ USACC Omaha 20717\Windsorworkplans\DataGatherins FINAUWork Plan\DataGathWP-12 doc 3-2 3.3 Wastewater Sump Drainage Verification

As a follow-up to the telephone conversation with a Weld County employee(s) familiar with the operations of the facility, a Baker representative will field verify the information.

3.4 Potentiometric Surface Study

To assess the possible interconnection between the wastewater drainage sump, the flame pit and the perched groundwater, a potentiometric surface study will be conducted. A month-long potentiometric surface study will be performed by installing pressure transducers in the wastewater drainage sump, the flame pit and three nearby wells (MW-5, MW-8 and MW-12). Data loggers will record the changes in water levels. Once during the month, a Baker teaming member (a representative of Brown and Caldwell - Denver) will confirm the appropriate operation of the equipment. The Baker Field team, using existing facility drawings, will calculate the water elevations of the flame pit and wastewater drainage sump.

3.5 UST Subsurface Soil Sampling

Drillpro Service, Inc., a local drilling company, will advance a Geoprobe soil boring to an approximate depth of 15 feet below the ground surface to determine the absence/presence of a fuel oil UST and associated contamination by the Launch Operations Building. A depth of 15-feet was selected to exceed the total depth of the UST (assume buried 4 ft. and 9 ft. in diameter). Three subsurface soil samples from the boring, including one from the bottom of the boring in native material, will be collected and analyzed for TPH-DRO, VOCs and SVOCs. The actual depth of the boring will be determined by the geologist and stratigraphy. The boring will be placed at the UST location. If the UST has been removed, the geologist should be able to identify the backfill, sub-base and native material. Soil samples submitted to the laboratory for analysis will be appropriate to determine the absence/presence of contamination.

3.6 Investigation Derived Waste Management

Soil spoils and decontamination fluids generated during the advancement of the Geoprobe boring will be screened using a P1D. If absent of VOCs, the soil will be placed back into the hole or at the boring

HA_USACE_Omaha 2071 TXWindsorworkplansVDataGatheringJTOALAWort Plan\DataGathWP-12 doc

3-3 location. If VOCs are detected or discoloring observed, the soil and decontamination fluid will be containerized in a plastic baggie or 5-gallon bucket, depending on the quantity generated. The containerized soil and decontamination fluids will be stored on site. Disposal of IDW will be dependent on the laboratory analytical results. IDW for these activities is expected to be very minimal. Purge water from water well sampling will be placed onto the ground surface.

3.7 QA/QC Samples

Quality Assurance/Quality Control (QA/QC) requirements for this investigation are presented in the QAPP. Tables 3-1 and 3-2 show the distribution of the QA/QC samples for the associated solid and aqueous samples. The following QA/QC samples will be collected throughout the course of the field sampling program:

• Trip Blanks - One trip blank will accompany the cooler containing aqueous VOC samples to STL and one to ECB.

• Equipment Rinsates - None planned

• Field Blanks - None planned

• Field Duplicates - Field duplicates for soil samples are collected at the same time as the environmental samples, homogenized and split. Field duplicate samples will be collected at a frequency of 10 percent. Field duplicates will be sent to STL and ECB.

« Matrix Spike/Matrix Spike Duplicates - No site-specific samples planned (MS/MSD samples will be analyzed by the laboratory per the QAPP). Where possible, enough sample will be provided to the laboratory to run the MS/MSD sample on one of the project samples for their batch MS/MSD.

H \ USAGE Oroaha_20717\Windsorworkplans\Da!aGalhering FlNALUVork Plan\DalaGalhWP-]2 doc 3-4 4.0 SAMPLE DESIGNATION

In order to identify and accurately track the various samples, samples collected during the field activities, including QA/QC samples will be designated with a unique number. This number will serve to identify the site, the sampling event, the sample media, sampling location, sampling depth and QA/QC qualifiers. The sample designation format is explained in the previous work plans.

This sample designation format has been consistent throughout the project. Required deviations to this format in response to field conditions or other factors will be documented in the field logbook. Table 4-1 provides a complete list of environmental samples that will be collected during this investigation, their designations and associated laboratory analyses. Further information regarding sample designations in provided in SOP A12 in the RI/SRE Work Plan.

4-1 5.0 INVESTIGATION PROCEDURES

The investigation procedures that are to be used for the field activities are discussed in the following sections. These procedures include performing a potentiometric surface study, subsurface soil sampling, equipment calibration, decontamination, and investigation derived waste management.

5.1 Water Well Sampling

One groundwater sample will be collected from the three wells identified on Figure 3-1. The wells include:

• Jess Anderson (Section 34) (approximately 4,450 feet northwest of the site) • Robert Anderson (off Route 257) (approximately 4,400 feet northwest of the site) • Kodak (Section 35) (approximately 3,350 feet north of the site) • unmarked structure (Section 3) (approximately 2,700 feet northwest of the site)

Sampling will be completed if access is granted and the well is accessible. The wells, if operational, will be sampled from the closest sampling port to the well or at an outside spigot. The well will be pumped for a minimum of 15 minutes. Inoperable wells will be sampled using a bailer, if accessible.

Groundwater samples will be collected as soon as possible after purging. The samples will be collected from the discharge port or the bailer into laboratory-supported containers. The samples will be collected in 40 ml vials with zero head space. The samples will be unpreserved with 14 day holding times. The samples will be analyzed for VOCs by Method 8260B. After collection, the samples will be placed in a cooler with ice and maintained at 4 degrees Celsius. Two QA/QC samples will be collected from the wells. Analytical parameters, number and size of containers, and QA/QC information are presented in the QAPP.

Due to the absence of free product in the wells at Site 12, the wells will not be checked for non- aqueous phase liquids (NAPL) and dense non-aqueous phase liquids (DNAPL). If possible, water level and well depth will be recorded in the Monitoring Well Log Book. A weighted tape may be necessary to measure the depth of the well due to well depth. Other data will include measurement time, date, and weather conditions. Water levels will be measured from the top of the casing located

H\ USAGE Omaha_207]7\WindsonvorkpIans\DalaGaIhenng_FINAL\Work PlanVDalaGathWP-12 doc 5-1 on the northern side of the casing. Water levels will be measured to the nearest 0.01-foot using an electric water level probe. Measurements also will be correlated to the ground surface. The wells will not be surveyed because it is a considerable distance from the site. Instead, the elevation of the well will be estimated, based on the USGS topographic map.

Purge water will be discharged to the ground surface. A groundwater collection form is provided in Attachment B.

5.2 Potentiometric Surface Study

A month-long potentiometric surface study will be performed by installing a pressure transducer in the wastewater drainage sump, the flame pit and three monitoring wells (MW-5, MW-8 and MW-12). Data loggers will record the water levels at each monitoring point every 30 minutes. Once during the month, a Baker teaming member (a representative of Brown and Caldwell - Denver) will confirm the appropriate operation of the equipment

The data will be evaluated and figures will be developed showing the responses of water levels in the monitoring wells, wastewater drainage sump, and the flame pit to precipitation and atmospheric pressure, respectively. The study will attempt to identify the flow relationship between the water in the wastewater drainage sump and flame pit and the surrounding perched groundwater.

5.3 UST Subsurface Soil Sampling

The subsurface soil sampling will be conduced using direct-push hydraulic sampling techniques (i.e., Gcoprobe). A decontaminated steel probe (Macro-Core Sampler), containing a 1.5-inch diameter, disposable plastic tube (contained inside the Macro-Core Sampler) will be hydraulically pushed over a 4-foot sampling interval, collecting an approximate 1.5-inch diameter core of the subsurface material. The total depth of the borehole is anticipated to be approximately 15 feet bgs. Figure 5-1 shows the approximate location of the direct-push soil boring (designated SB16).

H \ USACF. Omaha 2071 AWindsonvorkpIansXDataGathenng FINAlAWork PlanNDataGathWP-! 2 doc 5-2 Fill and geologic strata will be logged in the field by Baker's on-site representative. Soil descriptions including estimates of grain size, relative density, moisture content, staining, odor and other visual observations will be recorded on a HTW Drilling Log. An example HTW Drilling Log is provided in Attachment B.

A total of three subsurface soil samples will be collected from the soil boring and analyzed for TPH- DRO (Method 35506/Modified 8015B), VOCs (Method 8260B) and SVOCs (Method 3550B/8270C) by Severn Trent Laboratory (STL)- Pittsburgh, PA and North Canton, OH. In addition, one duplicate sample will be submitted to STL, as well as the USAGE Environmental Chemistry Branch (ECB) in Omaha, Nebraska. The ECB LIMS Number 6555 will be included on QA sample labels, COC forms and any other associated documentation sent to ECB as part of this project for Site 12. Due to the limited number of samples, no site-specific MS/MSD samples will be submitted for analyses (MS/MSD samples will be analyzed by the laboratory per the QAPP). Subsurface soil samples will be collected directly from the Macro-Core Sampler disposable plastic tube. Since disposable sample tubes will be used to collect the soil samples, no equipment blank will be collected. Samples will be placed directly in the appropriate, laboratory-supplied sample containers. Samples will be packed with ice in a cooler and shipped under chain-of-custody (refer to Section 6.2 for sample handling protocols). Soil sample collection information will be recorded on a soil sample record form (Attachment B). Decontamination water and soil sampling spoils will be placed back in the boring or on the ground surface adjacent to the boring.

Field PID Screening

The soil samples will be field-screened for total VOCs using a PID equipped with an 11.7 uV probe and calibrated to isobutylene. The PID readings will be recorded on the HTW Drilling Log.

For soils collected using the Geoprobe Macro-Core Sampler (disposable plastic liner), the following procedures will be used for field screening:

• Make a longitudinal cut across the entire length of the Geoprobe Macro-Core liner and separate the two edges of the liner

• Screen the entire length of the fill/soil core with a PID and record the readings along the core

H \ USACE_Omaha 20717\Windsorworkplans\DaIaGathering FINAL\Work P!an\DataGalhWP-l2 doc 5-3 General PID air monitoring to be conducted during the Geoprobe activities include:

• Periodic screening of the driller's breathing zone throughout the drilling program

• Screening at the top of the Geoprobe borehole between sampling runs

5.4 Field Equipment Calibration

The PID, pH, temperature and specific conductance meters will be calibrated/prepared following manufacture guidelines. Calibration readings will be documented.

5.5 Decontamination

Field decontamination procedures for sampling equipment are developed to ensure that representative samples are collected by reducing the potential for cross-contamination between sampling intervals, if necessary. Decontamination procedures include:

• Wash sample equipment in a potable water and low phosphate soap (alconox or liquinox solution) to remove residual material

• Rinse with potable water

• Distilled or deionized water rinse

• Shake vigorously and air dry (or dry with clean paper towel)

• Wrap in aluminum foil if stored/transported - shiny side out

5.6 Investigation Derived Waste Management

Soil spoils and decontamination fluids generated during the advancement of the Geoprobe boring will be screened using a PID. If absent of VOCs, the soil will be placed back into the hole or at the boring location. If VOCs are detected or discoloring observed, the soil and decontamination fluids will be

II \USACE Omaha 20717\WindsoTOorkplans\DalaGalhering_FINAL\Work Plan\DalaGathWP-12 doc 5-4 containerized in a plastic baggie or 5-gallon bucket, depending on the quantity generated. The containerized soil and decontamination fluid will be stored on site. Disposal of IDW will be dependent on the laboratory analytical results. IDW for these activities is expected to be very minimal. Purge water from water well sampling will be placed onto the ground surface.

5-5 6.0 SAMPLE HANDLING AND ANALYSIS

6.1 Sample Preservation and Handling

Sample preservation and handling procedures will be adhered to during the field programs to maintain sample integrity. Table 6-1 illustrates the sample containers, preservatives, and holding times for the soil samples. Additional sample preservation and handling procedures are provided in the QAPP.

6.2 Chain-of-Custodv. Sample Packing and Shipping

Proper chain-of-custody documentation will be maintained for samples from the time of collection until samples are shipped to the analytical laboratory. Chain-of-custody sheets accompanying the samples will contain the following information: project name, name of sample(s), sample numbers, number of containers, method(s) of preservation, date and time of sample collection, analyses requested, date and time of transportation to the laboratory, method of transportation (including air bill numbers, if applicable), and any other information pertinent to the samples.

The samples will be shipped in laboratory-supplied shipping containers to maintain sample integrity. Samples will be preserved with ice prior to transportation to the analytical laboratory. Samples will be shipped via an overnight courier to arrive before 12:00 noon the following day. Additional chain-of- custody procedures are provided in the QAPP.

6.3 Field Logbooks

Field logbooks will be used to record sampling activities and will serve as a daily summary detailing weather and activities of the day, including work accomplished and persons present on site. Field logbooks also will be maintained by site personnel to record the technical issues such as sample numbers, descriptions of sample locations, any problems encountered during their collection, and sample handling and preservation methods. In addition to the field logbook, field forms will be completed as support documentation for the field activities.

7.1 Field Team Responsibilities

The field portion of this project will consist of one field team. Field activities will be coordinated by a Site Manager (geologist). The Site Manager will ensure that field activities are conducted in accordance with the Work Plan. A technician will assist in field activities. One member of the field team will serve as the Site Health and Safety Officer.

7.2 Reporting Requirements

The Site Manager will report a summary of each day's field activities to the Project Manager. This may be done by telephone or telefax. Daily Quality Control Reports (DQCRs) will be completed every day during site activities and faxed daily to the USAGE Project Manager. The report will include, at a minimum, the following:

• Baker personnel on-site • Other personnel on-site • Major activities of the day • Samples Collected • Problems Encountered • Planned Activities

An example DQCR form is provided in Attachment B. The Site Manager will receive direction from the Project Manager regarding changes in the scope of the investigation. Changes in scope will be discussed and agreed upon by Baker and the USAGE prior to implementation.

This Quality Assurance Project Plan (QAPP) constitutes Section II of the Data Gathering Project Plans for sample collection and analyses to be conducted at F.E. Warren AFB Facility Atlas "E" Missile Site 12, and has been developed in conjunction with the Work Plan and the Health and Safety Plan (HASP) (Section III). This QAPP is a modification to the approved Site 12 QAPP dated May 1999 and addresses the quality assurance (QA) and quality control (QC) procedures and protocols to be followed for sample collection and analysis and is intended to address the analytical laboratory methods that will be used for this project. Site 12 is located near Windsor, Colorado. Baker is performing this project for the US Army Corps of Engineers - Omaha District (USAGE) under the Defense Environmental Restoration Program.

This QAPP has been prepared in accordance with USAGE 1110-1-263 and Guidelines and Specifications for Preparing Quality Assurance Program Plans (USEPA QAMS-004/80, November 1996) and the USAGE Omaha District General Chemistry Supplement to the Scope of Services (February 1996). The QAPP will not follow the outline identified on the current QAMS. This work is a continuation of work and data quality objectives initiated in 1996. Other applicable U.S. Environmental Protection Agency (USEPA) guidance documents were reviewed in the preparation of this QAPP.

The purpose of a QA Program is to establish policies for the implementation of regulatory requirements and to provide an internal means for control and review so that the work performed is of the highest professional standards.

5.1 Project Quality Assurance Objectives

Project QA objectives are:

• Scientific data will be of a quality sufficient to meet scientific and legal scrutiny.

• Data will be gathered/developed in accordance with procedures appropriate for the intended use of the data.

Data will be of acceptable precision, accuracy, completeness, representativeness, and comparability as required by the project.

The fundamental mechanisms that will be employed to achieve these quality goals can be categorized as prevention, assessment, and correction:

• Prevention of errors through planning, documented instructions and procedures, and careful selection and training of skilled, qualified personnel.

• Assessment of quality assurance sampling reports furnished by the contract laboratory.

• Correction of conditions which would subsequently jeopardize quality.

This QAPP, prepared in direct response to these goals, describes the QA Program to be implemented and the quality control (QC) procedures to be followed by the laboratory during the course of the project.

HA_USACE_Oimlu_M717IWindsorworkpUiB^DaBGalhcnng_nNAU«3APPlQAPP.WPD 5-1 This QAPP presents the project organization and specifies technical procedures, documentation requirements, sample custody requirements, audit, and corrective action provisions to be applied to provide confidence that activities meet the intent of the QA program. This plan has been prepared in accordance with USEPA guidance as presented in Guidelines and Specifications for Preparing Quality Assurance Program Plans (USEPA QAMS-004/80).

The procedures contained or referred to herein have been taken from:

"Test Methods for Evaluating Solid Waste," USEPA SW-846, November 1986,3rd Edition and Updates

5.2 Quality Assurance Objectives and Criteria

Data quality objectives (DQOs) are qualitative or quantitative statements developed by the data users to specify the quality of data needed from a particular data collection activity to support specific decisions made during the feasibility study. The DQOs are expressed in terms of precision, accuracy, representativeness, completeness, and comparability.

The volatile organic compound trichloroethene (TCE) is known to be present in the groundwater at the site. S W-846 Methods and the following DQOs have been chosen to meet the objective of defining contaminant type. Definitions for the DQO terminology, as well as for the more general term uncertainty, are provided below:

PRECISION - A measure of mutual agreement among individual measurements of the same property, usually under prescribed similar conditions. Precision is expressed in terms of the standard deviation. Comparison of replicate values is best expressed as the relative percent difference (RPD). Various measures of precision exist depending upon the "prescribed similar conditions".

ACCURACY - The degree of agreement of a measurement (or an average of replicate measurements), X, with an accepted reference or true value, T, expressed as the difference between the two values, X-T. Accuracy is a measure of the bias in a system.

H:\_USACE_Oiiulu_207l7VWindsoTOOtlplans\DaBGaUierinf_FINAUOAPPlQAPP.WPD REPRESENTATIVENESS - A qualitative element that is related to the ability to collect a sample that reflects the characteristics of that part of the environment that is to be assessed. Sample representativeness is dependent on the sampling techniques used and is considered individually for each project. Representativeness is a measure of how closely the measured results reflect the actual concentration or distribution of the chemical compounds in the sample. For this project, sampling will be performed by Baker. Sample handling protocols (e.g., storage, preservation and transportation) have been developed to preserve the representativeness of the samples. Proper documentation will establish that protocols have been followed and sample identification and integrity assured. Every attempt will be made to ensure that the aliquots taken for analysis are representative of the samples received.

COMPLETENESS - A measure of the amount of valid data obtained from a measurement system compared to the amount that was expected to be obtained, expressed as a percentage. Every attempt is made to generate completely valid data. It is recognized, however, that some samples may exhibit highly contaminated matrices necessitating multiple analyses and/or extensive dilutions. As a result of these atypical applications, recoveries and Method Detection Limits (MDLs) may be deemed questionable based on internal QC results. For this project, the QA objective for completeness is 95% for all analytical fractions.

COMPARABILITY - Comparability is considered during preparation of the work plan. The objective of comparability is to ensure that results of similar activities conducted by different parties are comparable. The use of EPA-approved or other methods and procedures ensure comparability with data from previous or following studies. The analytical methods to be used and associated quantitation, detection, or reporting limits are presented in Tables 9-1 through 9-3.

UNCERTAINTY - The likelihood of types of errors associated with a particular decision.

The intended use of the data, analytical measurements, and the availability of resources are an integral part in development of the DQOs. DQOs define the total uncertainty in the data that is acceptable for each specific activity during the investigation. This uncertainty includes both field sampling error and analytical instrument error. Ideally, zero uncertainty is the objective. However, the variables associated with sampling and analysis contribute to the uncertainty of the data. It is the overall objective to keep the total uncertainty within an acceptable range so uncertainty will not

5-3 hinder the intended use of the data. To achieve this objective, specific data quality requirements such as detection limits, criteria for accuracy and precision, sample representativeness, data comparability, and data completeness have been specified.

The goals for precision, accuracy, and completeness for this project will be assessed using results from internal as well as field quality control samples. The following criteria will be used to evaluate the data:

• Accuracy will be assessed through the use of spike (matrix and blank) recoveries. The recovery are presented in Tables 5-1 through 5-4.

• Precision will be determined by the calculated relative percent difference between duplicate analyses. The duplicate analyses can be either spiked duplicate analyses or simply duplicate analyses of a sample. The precision goals are presented in Tables 5-1 through 5-4.

• Completeness - the objectives for completeness is 95 percent.

The QA objectives for accuracy and precision are shown for project specific parameters in Tables 5- 1 through 5-4. If laboratory-specific limits are not available, control limits established by EPA and /or the method are used to judge acceptability of data generated by the laboratory. The laboratory will use control limits derived in-house through the use of control charts. Control limits will not automatically initiate reanalysis if they are not met; corrective action will be based on method requirements.

As stated previously, the DQOs are based on the end uses of the data to be collected. As such, different data uses may require different levels of data quality. To assist in the interpretation of data, the USEPA under the Superfund program has developed the following two descriptive data categories:

• Screening Data with Definitive Confirmation - Screening data are generated by rapid, less precise methods of analysis with less rigorous sample preparation. Screening data provide analyte identification and quantification, although quantification may be relatively imprecise. Screening data without associated confirmation data are not considered to be

H:\_USACE.Oinalu_207|-nWindsonvoik[)lansM>alaGallicring_FINAL\QAPIV)APPWPD -'"^ data of known quality. Examples of data to be collected as screening data are data generated onsite through the use of a photoionization detector (PID).

• Definitive Data - Definitive data are generated using rigorous analytical methods, such as approved USEPA reference methods. Data are analyte-specific, with confirmation of analyte identity and concentration. Methods produce tangible raw data (e.g., chromatograms, spectra, digital values) in the form of paper printouts or computer-generated electronic files. Data may be generated at the site or at an offsite location, as long as the QA/QC requirements specified in this QAPP are satisfied. For the data to be definitive, either analytical or total measurement error must be determined. Examples of data to be collected as definitive data are field sample analytical data.

5.3 Special Laboratory Training Requirements/Certification

The contract laboratory will be STL-Pittsburgh, which is located at the following address:

STL - Pittsburgh 450 William Pitt Way Pittsburgh, Pennsylvania 15238 412-820-8380

STL-Pittsburgh is a USACE-validated laboratory for VOCs (8260B) and SVOCs (8270C). STL- North Canton, OH will analyze for total petroleum hydrocarbons - diesel range organics (TPH- DRO). Currently, STL-North Canton is USAGE validated, but not for TPH-DRO. The sponsored USAGE project for which they were validated did not include TPH analysis. STL-North Canton can provide the TPH standard operating procedures to the USACE HTRW Center of Expertise, if necessary. Other STL laboratories may conduct some of the analyses depending upon the analyses methods and loading situation at the Pittsburgh laboratory. The point of contact and project manager at the laboratory is Ms. Carrie Gamber. STL - Pittsburgh laboratory validation from USACE-CX expires June 1,2002. Distribution of analyses to the associated STL laboratories is consistent with previous site investigations.

H:\_USACE_Omaha_20717\WiiidsonroikptmaDalaGaUlcnng_nNAL\QAPP\OAPP.WPD t>-2 7.0 SAMPLE AND DOCUMENT CUSTODY PROCEDURES

Sample custody procedures outlined in this section have been developed from "User's Guide to the Contract Laboratory Program," December 1988, OSWER Directive No. 9240.0-01. These procedures are in accordance with "EPA NEIC Policies and Procedure Manual," May 1978, revised November 1984, USEPA 330-78-001-R and EPA Guidance for Quality Assurance Project Plans. Quality Assurance Division, USEPA (EPA QA/G-5, November 1996).

The purpose of this section is to outline the sample handling and sample documentation procedures to be used during implementation of the Work Plan. The objective of the sample handling procedures is to deliver representative samples to the laboratories for analysis. The objectives of the sample documentation procedures are to: (1) ensure complete analysis of the requested parameters within the required holding and turnaround times; and (2) document the sample from the point of collection to the final data report.

7.1 Sample Handling and Containers

The objective of the sample handling procedures is to deliver representative samples to the laboratory for analysis. New polyethylene or glass bottles containing the proper preservatives will be provided by the laboratory. The sample containers will be pre-cleaned by the container supplier. The STL Laboratory Quality Manuals (LQMs) for the Pittsburgh and North Canton laboratories specifies the cleanliness of the sample containers. The LQMs were provided electronically to the USAGE. In addition to the chemical preservatives, samples will be stored on ice at 4°C in a waterproof sturdy plastic cooler. See Table 7-1 for summaries of the number and types of containers, preservation, and holding times for groundwater and solid samples for the various analytical methods specified in the June 2001 Scope of Services (SOS).

Temperature vials will be included with each sample cooler to ensure that samples are kept cooled to 4°C. Upon arrival of the sample coolers to STL, the temperature of the temperature vial will be measured. The laboratory's procedures for receiving samples are described in their LQM.

H:\_USACE_Omaha_207l7\Winiisorworkplai!!\DalaG3ll«:nng_nNAl.\OAI>P\OAPP.WPD 7-1 7.2 Chain-of-Custody Procedures

Custody of the samples will be maintained by Baker personnel from the time of sampling until the time they are forwarded to the laboratory. A sample is considered to be in an individual's possession if:

• It is in the sampler's possession or it is in the sampler's view after being in his (her) possession. • It was in the sampler's possession and then locked or sealed to prevent tampering. • It is in a secure area.

Five kinds of documentation will be used in tracking and shipping the analytical samples:

• Field log book • Sample labels Chain-of-Custody (COC) records • Custody seals • Commercial carrier airbills

At a minimum, the label for each sample bottle will contain the following information:

• Project name and number • Preservative • Analysis to be performed • Sample description • Sample ID number • Date and time of collection • Sampler's initials

Figure 7-1 presents an example label.

H:\_USACE_Oiialia_207n\WiiKlsoivTOttplaiK\DalaGallicring_nNAL\QAPP\QAPPWPD 7-' *9• The objectives of the sample documentation procedures are as follow: (1) to ensure complete analysis of the requested parameters within the required turnaround times, and (2) to document the sample from the point of collection to the final data report. Tables 6-1 and 6-2 list the type, number, and analysis of samples to be collected.

Throughout the sampling program, pertinent information will be recorded in the field log book and/or the applicable field sample collection record including, but not limited to the following:

• Soil sample ID • Sample number • Type and number of sample containers • Visual description of sample • Other observations and comments concerning sample conditions Field QA/QC samples collected • Date and time of sample collection, date and weather conditions • Names of sampling personnel

This information in conjunction with the COC record will be used to track samples in the field.

The sample custody is documented using COC records. An example COC is presented in Figure 7-2. Field personnel will complete a COC record, in waterproof ink, to accompany each cooler forwarded from the site to the laboratory. Any errors on the COC records will not be erased; instead, a line will be drawn through the error and initialed by the person completing the form. The original copy will be placed in a scalable plastic bag and put inside the appropriate cooler, secured to the cooler's lid. If additional duplicate sheets are required, the person relinquishing the samples will be responsible for filling out additional copies or making copies. The field supervisor will retain copies of the COCs for the project files. A copy of the completed form will be returned to the A-E by the laboratory for inclusion in the project report.

To ensure sample integrity during shipment and storage prior to analysis, each cooler will be sealed by the collector with a uniquely numbered Custody Seal (Figure 7-1). The seal will be securely adhered to the sample cooler and covered with clear tape in such a manner that the container cooler cannot be opened without the seal being broken. The seal number will be recorded on the COC

H:\_USACE_Omaln_20717\WiixlsomoikplaiisM3ala

If the sample shipment is hand delivered to the laboratory by field personnel or retrieved by laboratory personnel at the site, then the custody seals are not necessary. The laboratory sample custodian, or his/her designee accepting the sample shipment, whether it is from the air carrier or the field personnel, signs and dates the COC record upon sample receipt. The original COC record will be returned along with the final data report. The laboratory will be responsible for maintaining internal log books and records that provide a custody record during sample preparation and analysis.

Laboratory Chain-of-Custody Procedures

Upon sample receipt the following are performed:

• Samples are received and unpacked in the laboratory where the staff checks for bottle integrity (loose caps, broken bottles, temperature, etc.).

• Samples are verified with incoming paperwork (packing slip, etc.) by type of bottle and preservative. The paperwork is either signed or initialed.

• Information concerning the sample (from the sampling record, Chain-of-Custody, and observation) is recorded along with parameters to be analyzed, date of sampling, and date the sample is received in the laboratory.

• The contract laboratory will complete a cooler receipt form upon receipt of the sample coolers. Figure 7-3 presents an example of the form that will be used. The purpose of the cooler receipt form is to document the condition of the cooler and the samples (i.e., cooler temperature, broken bottles, adequate sample volume, correct paperwork, etc.).

Samples are placed in an appropriate secured storage area, e.g. refrigeration, until analysis.

H:\_USACE_Omsha_20717\WiiK)son«iitplans\DataGalhchiig_nNAL\OAPI^QAPP WPD ' "^ • When analysis is complete, samples are stored for a 30-day period unless otherwise specified.

If collected samples arrive without Chain-of-Custody or incorrect Chain-of-Custody records, or in poor condition (noted on the cooler receipt form), the following steps are taken:

• The laboratory prepares a nonconformance form stating the problem.

• The site supervisor and Project Manager are notified.

• If the missing information cannot be reconstructed by the Project Manager or field staff, the samples affected are removed from the sampling program.

Primary considerations for sample storage are:

• Secured storage.

Maintain prescribed temperature, if required, which is typically 4 degrees Celsius.

• Extract and/or analyze samples within the prescribed holding time for the parameters of interest.

7.3 Coordination of Sample Shipment to the Government QA Laboratory

ECB QA duplicates are collected concurrently with the field and duplicate samples. The samples are analyzed by the USAGE ECB. The samples will be shipped overnight to:

ECB Attn: Sample Custodian 420 S. 18th Street Omaha, NE 68102 (402)444-4314

H:\_USACE_Omaha_20717\WindsoTOorkplans\DalaGathcrins_FlNAHOAPPWAPP.WPD '~J The ECB LIMS Number 6555 will be included on QA sample labels, COC forms and any other associated documentation sent to the ECB as part of this project for Site 12. The number of environmental samples and associated QA/QC samples to be collected are presented in Table 6-1. A project team number will contact the ECB at least one week prior to the first delivery of samples. Additionally, a field team member will provide a minimum of 24 hours notice for Saturday deliveries.

8.1 Field Instruments

Field pH, temperature and specific conductance will be measured at the time the aqueous samples are collected. Calibration and preventive maintenance of field instruments will follow manufacture guidelines.

PID measurements will be measured in solid samples at the time the samples are collected.

8.2 Laboratory Instruments

The laboratory's procedures for calibration and related quality control measures are to be in accordance with the protocols presented in:

"Test Methods for Evaluating Solid Waste," USEPA SW-846, Nov. 1986, 3rd Edition and Updates.

Formal calibration procedures are established to ensure that instrumentation and equipment used for sample analysis are accurately calibrated and properly functioning. These procedures apply to instruments and equipment. Calibrations are performed by laboratory personnel or external agencies using standard reference materials per method specifications.

Calibrations are recorded on in-house calibration forms or instrument vendor forms or in dedicated bound notebooks. The following data are recorded for calibrations: the date, target readings, actual readings, instrument identification number, and the analyst's initials. Other data may be recorded depending upon the calibration performed.

Only properly calibrated and operating equipment and instrumentation are used. Equipment and instrumentation not meeting the specified calibration criteria are to be segregated from active equipment whenever possible. Such equipment is repaired and recalibrated before reuse. Equipment is uniquely identified, either by serial number or internal calibration number, to allow traceability

H:\_USACE_Omaha_20717\WiiKison»ortiplaiis\DalaGalhenng_nNAHOAl'P\OAPPWIl> 8-1 between equipment and calibration records. Recognized procedures (ASTM, USEPA, or manufacturer's procedures) are used for calibration whenever available.

8.2.1 Method Calibration

Method calibration is performed as part of the laboratory analytical procedure (calibration curves, tuning). Calibration curves are prepared using a minimum of five standards in graduated amounts across the appropriate range of analysis. New calibration curves are prepared based upon method criteria, which is typically based on failure of continuing calibration verification standards.

8.2.2 GC/MS System Calibration Procedure

This section outlines the requirements for the calibration of GC/MS (or GC/MSD) systems for the determination of volatile and semivolatile organic compounds. The following operations are performed in support of these requirements:

Documentation of GC/MS mass calibration and abundance pattern • Documentation of GC/MS response factor stability • Internal standard response and retention time monitoring.

Tuning and Mass Calibration

It is necessary to establish that a given GC/MS system meets the standard mass spectral abundance criteria prior to initiating data collection. This is accomplished through the analysis of p- bromofluorobenzene (BFB) for volatile compounds and decafluorotriphenylphosphine (DFTPP) for semivolatiles. The BFB and DFTPP criteria are met before any blanks, standards, or samples are analyzed.

A GC/MS system used for organic compound analysis is tuned to meet the criteria specified in SW- 846 for BFB analysis (volatile compounds) or DFTPP analysis (semivolatile compounds) for an injection of 5-50 nanograms (ng) of BFB. The analysis is performed separately from standard or blank analysis. These criteria are demonstrated at the beginning of the analytical shift/sequence and

H:\_USACE_OmahaJ0717\Windsonrotkiilaiis\DalaGallicnng_FINAL\QAPP\QAPP.WPD every 12 hours of continuous analysis. Background subtraction, if required, is employed to correct for instrument background ions. The tune must be acceptable in order to proceed with analysis.

GC/MS System Calibration

After tuning criteria have been met and prior to sample analysis, a minimum of five concentrations of compounds of interest are injected to determine response factors or calibration factors and define the linear range of the GC/MS system. Internal and surrogate standards are used with each calibration standard. Standards are analyzed under the same conditions as the samples.

• Relative Response Factor (RRF) Calculation - The USEPA specifies the internal standard to be used on a compound-by-compound basis for quantification. The relative response factor (RRF) is calculated for each compound at each concentration level.

• System Performance Check - A system performance check is performed and the minimum average relative response factors are met before the calibration curve is used.

• Calibration Check - A calibration check is performed and the criteria are met before the calibration curve is used. The percent relative standard deviation (%RSD) is calculated using the RRFs from the initial calibration.

• Continuing Calibration - A calibration check standard including surrogates is run each 12 hours of analysis. A system performance check is performed. The criteria are the same as for the initial calibration system performance check. A calibration check is also performed. The percent difference is determined for each target compound.

The % Difference for each compound must be less than or equal to 25%. The system performance check and calibration check criteria must be met before sample analysis can be performed. The continuing calibration is recorded on the continuing calibration forms.

H \_USACE_Oniaha_20717VWiiKisoivsrkplans\DauGalhenng_FINAUOAPPlQAPP.WPD 8-3 8.2.3 System Calibration Procedure for TPH-DRO Analysis

This section outlines the requirements that are used for calibration of gas chromatographic systems for the analyses of TPH-DRO. The following are performed in support of these requirements:

• Documentation of standard response • Monitoring consistency of instrument response

The calibration of TPH-DRO is markedly different from that for single component analytes. The response used for calibration must represent the entire area of the chromatogram within the retention time range.

TPH-DRO analyses are initially calibrated using a minimum of five standards at different concentrations. One of the standards should be at a concentration at or below the project-specific quantitation limit. The other concentrations should correspond to the expected range of concentrations found in real samples or should define the working range of the detector. The initial calibration must have a %RSD <20%. RSDs are calculated according to SW-846 method 8000.

The standard calibration curve must be verified at the beginning of each 12-hour work shift as a minimum requirement. Verification is accomplished by the measurement of a midpoint- concentration fuel calibration standard. In order to use the initial curve, the percent difference between the response factor for the verification standard and the initial standard must be less than 15%. If the percent difference is within acceptable limits, the analyses may continue. If the percent difference is greater than 15%, a new initial calibration must be performed.

Method SW-846 8015B requires a calibration check standard to be analyzed at the beginning and end of each 12-hour work shift. This monitors the consistency of the instrument response.

System cleanliness must be demonstrated through the analysis of daily solvent and method blanks.

H:\_USACE_Omalia_20717\Win(lsoiwoikplans\DaaGalhcnng_FINAUQAPP\QAPP.WPD 8.2.4 Periodic Calibration

Periodic calibration is performed on equipment required in analyses but not routinely calibrated as part of the analytical methodology. Equipment that falls within this category includes ovens, refrigerators, and balances. The calibration is recorded either on specified forms or in bound notebooks. Discussed below are the equipment, the calibration performed, and the frequency at which the calibration is performed.

• Balances are calibrated weekly with class S weights.

• The temperatures of the refrigerators are recorded daily.

• Liquid in glass thermometers are calibrated annually with the National Institute of Standards and Technology (NIST) certified thermometer. Dial thermometers are calibrated quarterly.

• The NIST Certified Thermometer is checked annually at the ice point.

The following equipment must maintain the following temperatures:

Sample Storage & Refrigerators: 4°±2°C

H:\_USACE_Onato_20717\Wii«ISOTO()ikplaiis\DaIiiCallienng_FINAI.\QAPP\OAPP.WPD 8-5 9.0 ANALYTICAL PROCEDURES

9.1 Field Analysis

Field pH, temperature and specific conductance will be measured in aqueous samples at the time the samples are collected. These analyses will be obtained in accordance with the "Handbook for Sampling and Sample Preservation of Water and Wastewater," September 1982, USEPA/600/4- 82/029.

PID will be measured in the soil samples at the time the samples are collected.

9.2 Laboratory Analysis

The samples that will be collected during the investigation will be analyzed according to the methods listed in Tables 9-1 through 9-3. The source and purity of analytical reference materials and laboratory chemicals necessary to perform the analyses are described in the LQM.

Compounds and the corresponding method performance limits are also listed in Tables 9-1 through 9-3. Terms that are commonly associated with analytical method requirements and found in the above referenced tables are defined as follows:

Detection Limit (DL) -The lowest concentration of a chemical that can be detected above the normal, random noise of an analytical instrument or method. Roughly equivalent to two times the standard deviation (SD) for 7 replicate analyses. Often, the term "detection limit" is used genetically to describe two types of detection limits: PQLs and RLs.

Practical Quantitation Limit (PQL) -Lowest level that can be reliably determined within specified limits of precision and accuracy during routine laboratory operations. Later updates of the S W-846 methods refer to estimated quantitation limits (EQLs) instead of PQLs, which are synonymous. PQLs are roughly equivalent to thirty times the standard deviation (SD) for 7 replicate analyses, and is generally 5 to 10 times the method detection limit (MDL). The MDL is the limit representing a 99% confidence that the concentration is greater than zero, and is established as the product of the

H:\.USACE_Oniaha_20717\WiiidsonTOrkplilns\DalJiGallicriiig_FINAUQAPPiQAPP.WPD "~ * SD (for 7 replicate analyses) and the Student t-value at the desired confidence level (3.14 for 7 replicates).

Reporting Limit (RL) - For most analytical methods, the RL and the PQL are the same. The RL is the value used by the laboratory below which data qualification would be necessary. However, the RL is more flexible than the PQL, which is defined by clearly specified limits, in that the RL can be determined by project-specific needs. For example, if it is specified that results for a particular analysis are to be reported to the MDL for some project, then the MDL becomes the RL for that project.

10.1 Field Data Procedures

The documentation of sample collection will include the use of field forms and bound field log books in which information on sample collection will be entered in indelible ink. Appropriate information will be entered to reconstruct the sampling event including: site name (top of each page), sample identification, brief description of sample, date and time of collection, sampling methodology, field measurements and observations, sampler's initials (bottom of each page, and dated), and other information listed in Section 7.2.

Baker will require a rigorous data control program to ensure that documents for the investigations are accounted for when they are completed. Accountable documents include items such as log books, field data records, correspondence, chain-of-custody records, analytical reports, data packages, photographs, computer disks, and reports. Field records will be completed corresponding to the collection of the groundwater samples. The project manager is responsible for maintaining a project file in which accountable documents will be inventoried. The project records will be retained for a period of 10 years after project close-out.

10.2 Laboratory Data Procedures

The following procedures summarize the practices routinely used by laboratory staff for data reduction, validation, and reporting. Numerical analyses, including manual calculations, are documented and subjected to quality control review. Records of numerical analyses are legible and complete enough to permit reconstruction of the work by a qualified individual other than the originator. The equations and procedures used for calculations, as well as the units, are specified in the referenced analytical protocols.

10.2.1 Laboratory Data Validation

Data validation begins with data reduction and continues through to the reporting of data.

HA_USACE_Oiiiaha_207I7\Wmdson«iriiptiiis\DalaGatliciing_nNAL«3APfV3APP.WPD 10-1 Data processing is checked by an individual other than the analyst who performed the data processing. The checker reviews the data for the following:

• Utilization of the proper equations. • Correctness of numerical input. • Correctness of computations. Correct interpretation of raw data (chromatographs, strip charts, etc.). • Data is transferred to the proper forms and checked for transcription errors.

The checking process is thorough enough to verify the results.

Entries made in benchbooks, data sheets, computation sheets, input sheets, etc. are made in ink. No entry will be rendered unreadable.

10.2.2 Analytical Reports

11.1 Field Internal Quality Control Checks

Field internal quality control checks to be used include field duplicates and QA duplicates. The applicable media and frequency of quality control is described in Section 6.0 and can also be found in the LQM. The results from the field quality control samples will be used to determine the overall quality of the data. Specific quality control procedures for the equipment are included in Section 8.1.

11.2 Types of OC Samples

Documentation of the analyses of the following types of QC samples (laboratory and field) is maintained in the laboratory bench notebooks and/or the specific client or project files.

11.2.1 Trip Blank

Trip blanks apply only to VOC aqueous samples. Trip blanks are prepared by the laboratory prior to the sampling event in the actual sample containers and are kept with the investigative samples throughout the sampling event. A trip blank consists of a sample vial filled with deionized/distilled water and preserved like an actual sample. They are packaged for shipment with the other samples and sent for analysis. The purpose of the trip blanks is to check for migration of VOCs from air at the site or in the shipping container, into the sample vials.

11.2.2 Method Blank

Analysis of method blanks is performed to verify that method interferences caused by contamination in reagents, glassware, solvents, etc. are minimized and known.

Method blanks are initiated by the analyst prior to the preparation and/or analysis of the sample set. A method blank consists of a volume of deionized water or organic-free water equal to the sample volume which is carried through the entire analytical procedure. For solid samples to be analyzed by GC/MS, the method blank consists of a purified solid matrix approximately equal to the sample

H:^USACE_Oituha_20717\WindsonvorkplansJDalaGalhering_FINAL\QAPP\OAPP.WPD 11-1 weight. A method blank is analyzed with each set of samples or at the very least, daily. If the analytical data of the method blank are outside criterion given in SW-846 Method 8000, the source of contaminant will be determined. The samples may be reanalyzed or the data may be processed as is depending upon the nature and extent of the contamination.

11.2.3 Field Duplicates

Field duplicates consist of two samples collected independently at a sampling location during a single episode of sampling. Duplicates are analyzed to provide statistical information concerning sampling variability. Field duplicates are collected and analyzed at a minimum rate of 1 in 10 investigative samples.

11.2.4 Duplicate Sample Analysis

Duplicate sample analysis is performed to demonstrate the precision of an analysis. An interlaboratory duplicate sample is initiated by the analyst prior to sample preparation and carried through the entire analytical procedure.

11.2.5 QA Duplicates/Splits

QA duplicates are collected concurrently with the field and duplicate samples. The samples are analyzed by ECB. The QA duplicates are analyzed to provide a check of the contract laboratory.

11.2.6 Laboratory Control Samples

A laboratory control sample (LCS) is a laboratory-generated clean matrix sample that is fortified with the target analytes of concern spiked at or near the levels of concern. Review of the LCS recovery data is used to monitor the performance of the analytical methods.

H:\_USACE_Omaha.207n\WindsorwoikplansM)auiGalhenng_nNAL\QAPP\QAPP.WPD 1 1-.£ 11.2.7 Surrogate Standards

Surrogate standard analysis is performed to monitor the preparation and analyses of samples. Samples and blanks are fortified with a surrogate spiking solution prior to extraction or purging.

11.2.8 Internal Standards

Internal standard analyses are performed to monitor system stability. Prior to injection or purging, internal standards are added to blanks and samples.

11.2.9 Matrix Spikes and Matrix Spike Duplicates

A matrix spike is an aliquot of a matrix (soil) fortified (spiked) with known quantities at or near levels of concern of target analytes of concern and subjected to the entire analytical procedure in order to indicate the appropriateness of the method for the matrix by measuring recovery. A matrix spike duplicate is a second aliquot of the same matrix as the matrix spike that is spiked in order to determine the precision of the method. A matrix spike and matrix spike duplicate will be performed at a frequency of 1 per 20 samples received per matrix type or one per batch (of samples), whichever is greater. No site-specific matrix spike/matrix spike duplicate samples are proposed for this project due to the limited number of samples to be collected. Where possible, enough sample will be provided to the laboratory to run the MS/MSD sample on one of the project samples for their batch MS/MSD. The laboratory reports will include the batch MS/MSD sample results and associated QC results.

11.3 Laboratory Control Limits

Control limits are established for QC checks (spikes, duplicates, blanks, etc.). S W-846 control limits for surrogate standards spikes and duplicates are adopted. Control limits for spikes, duplicates, and reference samples are determined internally through statistical analysis.

Whenever an out-of-control situation occurs, the cause is determined. Any needed corrective actions are taken.

H:\JJSACE_Omaha_20717\WindsonvoifcplaiE\IfeuGatlicniig_nNAL\QAPP\QAPP WPD 11-3 11 J.I Method Blanks

The following criteria are used for method blank analysis:

• A method blank for volatiles analysis must contain no greater than five times the detection limit of common laboratory solvents (common laboratory solvents are: methylene chloride, acetone, toluene, 2-butanone, and chloroform).

• A method blank for semivolatiles analysis must contain no greater than five times the detection limit of common phthalate esters.

• For other compounds not listed above (i.e., VOC target parameters, SVOC target parameters, and TPH-DRO), the method blank must contain less than the detection limit of any single compound. If a method blank exceeds the criteria, the analytical system is considered to be out of control. The source of the contamination is investigated and appropriate corrective measures are taken and documented before sample analysis proceeds. Samples processed with a method blank that is out of control (i.e., contaminated) are reextracted/repurged and reanalyzed, when possible. If the affected samples cannot be reextracted/repurged and reanalyzed within the method holding times, the flagged sample result and the blank result are both reported. The sample is not corrected for the blank value.

11.3.2 Surrogate Standards

For surrogate standard analysis, corrective action is taken if any one of the following conditions exist:

• Recovery of any one surrogate compound in the volatile and TPH-DRO fractions and any two surrogate compounds from one semi-volatile fraction is outside the required surrogate standard recovery limit.

H:\_USACE_Oniaha_207n\Windsorwoikplaiis\DaLiGalhcnn|l.FINAHOAPI»vQAPP.WPD 11-4 Corrective action will include the following:

• A check of: the calculations for errors; the internal standard and surrogate spiking solutions for degradation, contamination, etc.; and instrument performance.

• A check of: the calculations for errors; the internal standard and surrogate spiking solutions for degradation, contamination, etc.; and instrument performance.

• Recalculating or reanalysis of the sample or extract, if the above corrective action fails to solve the problem.

• Reextraction and reanalysis of the sample, if none of the above are a problem.

11.4 Quality Assurance Review of Reports. Plans, and Specifications

Prior to issuance of a final report, it is reviewed by senior-level program staff, the Project Manager, or a designated representative. This review addresses whether:

• The report satisfies the scope of work, client requirements, and pertinent regulatory requirements.

• Assumptions are clearly stated, justified, and documented.

• A reference is cited for any information utilized in report preparation that was originated outside the project.

• The report correctly and accurately presents the results obtained by the work.

• The tables and figures presented in the report are prepared, checked, and approved according to requirements.

• The report figures are signed and dated by the appropriate members of the project staff and project management.

11.5 Laboratory Quality Assurance

See Section 11.2.

11.5.1 Field Quality Assurance

Two types of field QA/QC samples will be submitted to the laboratory: trip blanks and field duplicates. A summary of the number of environmental and QA/QC samples to be submitted for analysis is given in Tables 6-1 and 6-2.

Field duplicate samples will be given unique numbers consistent with the field sampling scheme to ensure that the laboratory cannot identify duplicate samples.

H:\_USACE_Omalia_2(17mWiiidson»orkplaiis\DauiC3lhcnng_FINAl.VQAPP\QAPP.WPD 11-6 12.0 PERFORMANCE AND SYSTEM AUDITS

No field audits will be conducted during the sampling investigation; however, Baker will continually monitor, record, and immediately act to correct problems should any occur in the field. Laboratory audits are the responsibility of USAGE through their internal laboratory certification process.

H:\_USACE_Oireilia_207l7\WiiKlsor»oll|>lans«)aBOMhenng_nNAL\QAPP«3AI>P.WI>D 1.2- 1 13.0 PREVENTIVE MAINTENANCE

13.1 Field Maintenance

The pH, specific conductance, temperature meters, and PID to be used during sampling will be maintained according to manufacture guidelines.

13.2 Laboratory Maintenance

Preventive maintenance is an organized program of actions to prevent instruments and equipment from failing during use and to maintain proper performance of equipment and instruments. A comprehensive preventive maintenance program is implemented to increase the reliability of the measurement system. The preventive maintenance program addresses the following:

• Schedules of important preventive maintenance tasks that are carried out to minimize downtime.

• Lists of critical spare parts that are available to minimize downtime.

The laboratory maintains histories, in instrument/equipment logs, of major equipment. Trouble shooting, maintenance, and spare parts inventory are recorded in the logs. Instruments and equipment are maintained periodically according to SW-846, third edition requirements, manufacturer's recommendation, and/or service contracts.

The modern analytical laboratory depends heavily upon instrumentation and equipment; therefore, cleaning and preventive maintenance are primary considerations in the sustained production of satisfactory data. Specific requirements for proper care of laboratory instrumentation and equipment are contained in the manufacturer's instructions; however, some general guidelines are considered, and are listed below:

• Special precautions are taken to avoid spillage of corrosive chemicals on or around equipment and instrumentation not only to extend the life of the item, but also to eliminate contamination.

H \_USACE_Omaha_20717\Windsorworicplans\DaIaGaIhering_FlNAL\QAPP\QAPPWPD 13-1 • Where available, covers are placed on instrumentation when not in use.

• Instrument parts are cleaned as required (i.e., mirrors, probes, detector cells).

Laboratory equipment maintenance is also presented in the LQM.

H;>_USACE_Omaha.20717\WinP\QAPP.WPD 14.0 DATA MEASUREMENT ASSESSMENT PROCEDURES

14.1 Overall Project Assessment

Overall data quality will be assessed by a thorough understanding of the data quality objectives which are stated during the design phase of the investigation. By maintaining thorough documentation of decisions made during each phase of sampling, performing field and laboratory audits, thoroughly reviewing the analytical data as they are generated by the laboratory, and providing appropriate feedback as problems arise in the field or at the laboratory, data accuracy, precision and completeness will be closely monitored.

14.2 Field Quality Assessment

To assure that field data are collected accurately and correctly, the project manager will require that personnel involved in field data acquisition fully understand and follow the Work Plan/QAPP.

The evaluation (data review) of field records and QC samples will provide indications of the data quality. If a problem that can be isolated arises, corrective actions can be instituted for future field efforts.

14.3 Laboratory Data Quality Assessment

As part of the analytical QA/QC program, the laboratory applies precision and accuracy criteria for each parameter that is analyzed. When analysis of a sample set is completed, QC data generated are reviewed and evaluated to ensure acceptance criteria are met. These criteria are method and matrix specific.

QA/QC data review is based on the following criteria:

• Method Blank Evaluation - The method blank results are evaluated for high readings characteristic of background contamination. If high blank values are observed, laboratory glassware and reagents are checked for contamination and the analysis of future samples halted until the system can be brought under control. A high background is defined as a

H:\_USACE_Omaha_20717\WindsotwoiVptaiis\DaIaGalhcnng_FlNAI,«}APP\OAI'PWPD 14-1 background value sufficient to result in a difference in the sample values, if not corrected, greater than or equal to the smallest significant digit known to be valid. A method blank must contain no greater than two times the parameter detection limit for most parameters.

• Trip Blank Evaluation - Trip blank results are evaluated for high readings similar to the method blanks described above. If high trip blank readings are encountered (i.e., a value sufficient to result in a difference in sample values, if not corrected, greater than or equal to the smallest significant digit known to be valid), procedures for sample collection, shipment, and laboratory analysis are reviewed. If both the method and trip blanks exhibit significant background contamination, the source of the contamination is probably within the laboratory. Ambient air in the laboratory and reagents are checked as possible sources of contamination.

• Standard Calibration Curve Verification - The calibration curve or midpoint calibration standard (check standard) is evaluated daily to determine curve linearity through its full range and that sample values are within the range defined by the low and high standards. If the curve is not linear, sample values are corrected. If average response factors are used to calculate sample concentrations, these factors are verified on a daily basis. Verification of calibration curves and response factors is accomplished when the evaluated response for any parameter varies from the calibrated response by less than ranges specified in Section 7.0.

• Duplicate Sample Analyses - Duplicate sample analyses are used to determine the precision of the analytical method for the sample matrix. Two types of duplicate samples are analyzed for this project, field and interlaboratory. Duplicate results are used to calculate precision as defined by the Relative Percent Difference (RPD). If interlaboratory duplicate values exceeds the control limit, the sample set are reanalyzed for the parameter in question. Precision limits are updated periodically following review of data.

• Laboratory Control Sample Analyses - The results of laboratory control sample analysis are compared with true values, and the percent recovery of the laboratory control sample is calculated. If correction is required (excessive or inadequate percent recovery), the sample is reanalyzed to demonstrate that the corrective action has been successful.

HA_USACE_Oinato.20717\WindsoiwoHii>lans\DiilaG3thehng_FINAL\OAPP«JAl>P WPD 1 Q~2. • Surrogate Standard Analyses - Surrogate standard determinations are performed on samples and blanks. Samples and blanks are fortified with surrogate spiking compounds before purging or extraction to monitor preparation and analysis of samples. Recoveries must meet specific criteria. If acceptance criteria are not met, corrective action is taken to correct the problem and the affected sample is reanalyzed.

• Matrix Spike Analyses - The observed recovery of a spike added to a sample versus theoretical spike recovery is used to calculate accuracy as defined by the percent recovery (% R). If the accuracy value exceeds the control limit for the given parameter, the appropriate laboratory personnel are notified and corrective action is taken before the sample set is reanalyzed for the parameter in question.

For completeness, it is expected that the methodology proposed for chemical characterization of the samples will meet QC acceptance criteria for at least 95% of sample data. To ensure this completeness goal, sample data that do not meet the established criteria will be recollected, reextracted, or reanalyzed.

Data representativeness will be ensured through the use of appropriate analytical procedures, and analysis of samples performed within the allowed holding times.

Comparability is a qualitative characteristic of the data. By using standard methods for sampling and analyses, data generated in past or future investigations will be comparable with this investigation data.

14.4 Laboratory Data Evaluation

Baker's QA/QC Officer will review the laboratory data packages to verify necessary paperwork (e.g., COC records, analytical reports, and laboratory personnel signatures) and deliverables are present. In addition, a limited quality control review will be completed based on "National Functional Guidelines for Organic and Inorganic Data Validation" and in conjunction with the DQOs established in this QAPP. Raw data and chromatograms will not be reviewed as part of the evaluation.

H:\_USACE_OnialB_2C717\WiiidsoTOoitplaiis\DalaGalhchnK_FINAUQAPPW3APP.WPD 14-3 Proposed action limits are presented in Tables 9-1 through 9-3 of the QAPP to facilitate comparisons with corresponding laboratory MDLs/RLs. The proposed action levels include USEPA Region III Risk Based Concentrations (RBCs) and Federal/State MCLs, as available.

14.5 Data Validity

H A_USACE.Oitiata_20717\Winoralki>laiis\DauGaihen»t.FINAL\OAPP\QAPP.WPD ' 4-4 15.0 CORRECTIVE ACTION

Errors that require corrective action will be identified by the Project QA/QC Officer based on the officer's technical judgment and the procedure identified in this Plan. If procedural errors are noted during the observation or review of field activities by the Project QA/QC Officer, or his designee, corrective action will be initiated immediately. The corrective action will consist of the Project QA/QC Officer advising field investigation personnel of procedural deficiencies and monitoring their performance until procedures are being conducted correctly. Corrective actions may include, but are not limited to, resampling, reanalyzing samples, or auditing field laboratory procedures.

Serious deficiencies will be reported verbally to the USACE-PM within forty-eight (48) hours of the time of discovery of the deficiency, including actions taken or to be taken to correct such deficiencies. The deficiencies and corrective actions taken will be documented in the Analytical Data Package (ADP) (Section 4.16). Laboratory corrective action is explained in the LQM.

The health and safety of site personnel and the public are a primary concern during investigative and remedial activities at potentially hazardous sites. This site-specific Health and Safety Plan (HASP) presents the conditions and hazards known or anticipated to be present at the former F.E. Warren Air Force Base, Atlas E Missile Site 12, Windsor, Colorado. This HASP will be used by Baker Environmental, Inc. (Baker) to identify and mitigate potential site and task-specific hazards and to select appropriate health and safety protective measures to be used during future tasks and operations at the facilities. This HASP is a modification to the approved Site 12 HASP dated May 1999.

This HASP has been developed based on available information pertaining to the former Warren AFB and contains information pertinent to the general conditions at the facilities such as general site information, hazard evaluation and control, personnel responsibilities and requirements, a general description of personal protective equipment, customary decontamination procedures, and emergency response procedures.

1.1 Policy

It is the policy of Baker that on-site hazardous waste management activities be performed in conformance with a site-specific HASP. This document is written based on the anticipated hazards and expected work conditions at this site and applies to field activities to be performed under this project. Applicability of this site-specific HASP extends to Baker employees, Baker's subcontractors, and visitors entering the site. However, subcontractors are expected to provide their own HASP and relevant Standard Operating Procedures (SOPs) that pertain to the activities they are contracted to perform on site. Personnel must review the site-specific HASP and sign an agreement to comply with its provisions prior to commencing on-site work. This site-specific HASP is considered an operational document, which is subject to revisions in response to various site-specific conditions which, may be encountered. However, it may be modified/updated only with the approval of the Project Health and Safety Officer (PHSO) and Project Manager. Proper notification will be given to the U.S. Army Corp of Engineers (USAGE) Omaha District if significant changes to the HASP are implemented.

H \_USACE_Omaha_20717\Windsorworkplilns\DaaGathering_FtN AL\HASP\ACEHASP WPD

1-1 This site-specific HASP is based on a outline developed by the United States Coast Guard (USCG) for responding to hazardous chemical releases (USCG Pollution Response COMDTINST- MI6465.30) and by the National Institute for Occupational Safety and Health (NIOSH), the Occupational Safety and Health Administration (OSHA), the USCG, and the United States Environmental Protection Agency's (USEPA) recommended health and safety procedures (Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities). This HASP will, at a minimum, meet the requirements under OSHA Standard 29 Code of Federal Regulations (CFR) 1910.120 (Hazardous Waste Operations and Emergency Response).

1.2 Scope of Work

The field tasks involved with this project are as follows:

• Mobilization/demobilization • Water Well Location Confirmation and Well Sampling • Wastewater Sump Drainage Verification Potentiometric Surface Study • UST Subsurface Soil Sampling • Equipment Decontamination • Investigation Derived Waste Management (Includes direct-push drilling)

3.1 Site Description and History

Site 12 is located approximately three miles southeast of Windsor and six miles west of Greeley, Colorado. The original site consisted of approximately 260 acres that was acquired by fee or condemnation in the early 1960s. Site 12 was one of nine Atlas "E" missile sites operated by the Air Force under the 549th Strategic Missile Squadron at F.E. Warren AFB, Cheyenne, Wyoming. Site 12 reportedly operated as an active missile site between the years of 1961 and 1965. Site 12 is currently owned by Weld County. Weld County uses the facility for storage and Mr. Pete Ambrose lives on the site as the property caretaker.

The immediate area surrounding the site is primarily ranch land and sparsely populated. The closest residence is approximately 1.2 miles south of the site.

A historical archive information review for Intercontinental Ballistic Missile (ICBM) facilities, which includes notes from interviews with the combat crew members, indicates that TCE was used at the Atlas "E" missile facilities. The crew members reported that the waste TCE and residual rocket fuel were dumped into the flame bucket (flame pit), which flowed to the wastewater drainage sump via a floor drain. Liquid collected in the drainage sump either infiltrated into the ground (subsurface) or was subsequently discharged to the ground surface at the sump discharge headwall via sump pumps operated by a float control system. The disposition of the TCE, and potentially residual RP-1 rocket fuel, into the flame pit, the subsurface and discharge is believed to have contributed to groundwater contamination at the site. Other than this practice, there are no known waste disposal activities on record.

3.2 Hazard Evaluation

The pre-entry briefing and subsequent meetings will serve to address the hazards particular to each area under investigation such as sloping ground, uneven terrain, etc. If new hazards are identified, the SHSO will then add them to the site-specific HASP in the field, along with the date of modification. Additionally, site personnel will be expected to follow safe work practices as

H:\_USACE_Omaha_207l7\Windsonvorkplans\DataGathering_FINAL\HASPUCEHASPWPD 3-1 described in this site-specific HASP. The following sections identify the potential chemical, physical, radiological, environmental, and task specific hazards at Site 12.

3.2.1 Chemical Hazards

Hazardous chemicals can be absorbed into the body through various pathways. These pathways include:

• Inhalation of vapors, gases, or particulates. • Ingestion of contaminated particulates from hand-to-mouth contact. • Dermal and eye absorption from direct, unprotected contact, or from exposure to airborne concentrations.

Intravenous and intraperitoneal routes are also absorption pathways, but are not typical routes of concern for these types of activities. The pathway of greatest concern for potentially acute exposures would be inhalation.

The chemical exposure potential for personnel involved with the field investigation is expected to relate directly to the results of a previous investigation indicating groundwater contamination. The primary historic chemical hazards at the site during soil sampling are TCE and cis 1,2- dichloroethene. The primary routes of entry concern will be from inhalation and ingestion. Material Safety Data Sheets for TCE and cis 1,2-dichloroethene are contained in Attachment A. The following table identifies the chemical and physical properties for the chemicals of concern, detected during previous sampling investigations at Site 12.

(b) Hazard Rating - based upon Health (H), Fire (F), or Reactivity (R) hazard from NFPA 704 Standard Rating system (0 = no hazard, 4 = high hazard) (c) Volatility Rating - based upon vapor pressure in mm Hg at 68°F, 20°C (d) Skin Absorption - "Yes" indicates potential exposure through skin and mucous membranes, either by airborne or, more particularly, by direct contact - ACGIH (e) Carcinogen - 2001 ACGIH - Al - Classified as confirmed human carcinogen A3 - Classified as confirmed animal carcinogen with unknown relevance to humans A5 - Classified as not a suspected human carcinogen <° TWA - Time Weighted Average from the 2001 TLV - Threshold Limit Value of the ACGIH or OSHA Permissible Exposure Limits (PEL), whichever is lower (8) IDLH - Immediately Dangerous to Life and Health. (h) lonization Potential - expressed in electron volts (eV)

At Site 12, efforts will be made to eliminate or reduce potential routes of exposure through the use of safe practices such as performing investigative activities in an upwind location, wearing the specified personal protective equipment (PPE), avoiding hand-to-mouth contact, and immediately washing the hands and other parts of the body that may have contacted the media of concern.

3.2.2 Physical Hazards

Physical hazards that are potential concerns for Site 12 activities are discussed below:

3.2.2.1 Confined Space Entry

Confined space entry is not anticipated during activities to be conducted at Site 12; therefore, confined space entry procedures have not been provided. However, should circumstances arise that may require entry into a confined space, the PHSO will be contacted and entry-specific procedures according to 29 CFR 1910.146 will be provided at that time.

H \_USACE_Omaha_207l7\WindsorworkplaiB\DataGathering_FINAL\HASP\ACEHASP.WPD 3-3 3.2.2.2 Thermal Stress

Provisions for monitoring of heat stress and cold stress are outlined in Attachment C of this HASP.

3.2.2.3 Noise

Elevated noise levels are not anticipated during field activities; however, elevated noise may be produced during drilling operations. The SHSO is responsible for making this determination based on past experience with the type of equipment in use, and the proximity of personnel to the equipment.

3.2.2.4 Explosion and Fire

Explosion and fire are not anticipated during field activities. In general, the following items present potential explosion or fire hazards facility-wide, and will be monitored closely as they pertain to each site. Explosion and fire resulting from:

• Heavy equipment malfunction

• Penetration into underground utility/service lines (i.e., gas, electric, fuel)

• Ignition of trapped flammable vapors

• Puncturing of drums or containers during drilling operations

• Ignition of munitions from the operating frequency produced by site communication devices, (i.e., two-way radios and mobile phones).

Provisions for monitoring of potential fire/explosive conditions will include the performance of utility checks prior to conducting intrusive activities. The SHSO will be responsible for this determination, in consultation with the PHSO.

HA_USACE_Omaha_20717\Windsonvorkplans\DaaGathering_FINAL\HASP\ACEHASP.WPD 3-4 3.2.2.5 Utilities

Utility clearances were performed by USAGE and Baker during the SI; however, another underground utility review of existing drawings and clearance by onsite personnel will be completed prior to soil sampling. If underground utilities are identified, the ground above the utility lines will be physically marked with spray paint or flags and the sample relocated. The generally accepted uniform color code for underground utilities is:

• Red - Electric power lines, cables, conduit and lighting cables • Yellow - Gas, oil, steam, petroleum, or gaseous materials • Orange - Communication, alarm or signal lines, cables or conduits • Blue - Water, irrigation, and slurry lines • Green - Sewers and drain lines • White - Proposed excavation

No known overhead electric lines are present at the proposed soil boring location; therefore, no energized overhead electric lines present a risk of electrocution. OSHA standards require that equipment maintain certain distances from power lines. For lines 0 to 50 kilovolts (kV), the minimum distance is 10 feet. Lines carrying over 50 kV require that equipment maintain a distance of 10 feet plus an additional 0.4-inch for each 1 kV over 50. On very humid days or during episodes of rain, these distances will be doubled.

In the event that utilities are damaged due to investigative activities, the Fire Department will be contacted at 911.

3.2.2.6 Heavy Equipment

One of the primary physical hazards for any site, where applicable, will be the use of heavy equipment, such as the drill rig. A truck mounted direct-push Geoprobe will be used during these activities. Only operators trained, qualified, and authorized will be permitted to operate this and other pieces of heavy equipment.

H \_USACE_Omaha_20717\Wmdsorworkplans\DataGalhering__FIN AL\HASP\ACEHASP.WPD 3-5 General hazards associated with the drill rigs in general include moving parts. Personnel must remain clear of moving parts and must avoid loose fitting clothing that can become entangled in the moving parts. Personnel working near a drill rig must be aware of the location and operation of the emergency shut off devices. Personnel are to stand clear of the drill rig immediately prior to starting the engine.

Noise from the operation of the heavy equipment may limit verbal warning abilities. Hand signals will be prearranged between operators and personnel working in and around heavy equipment. Backup alarms and lights must operate properly on the heavy equipment.

The drilling rig operators/site supervisors will address other cautions that need to be observed when working around this equipment during the site-specific HASP pre-entry briefings.

3.2.2.7 Solar Radiation

Exposure to solar radiation is anticipated to be high during this project. Ultraviolet radiation, a component of solar radiation, can cause sun burn, skin cancer, and cataracts. Workers should attempt to minimize the amount of exposed skin and should apply sunscreen (minimum SPF 15) to reduce exposure.

3.2.3 Radiation Hazards

The potential for exposure to radiological wastes or radioisotopes at Site 12 is considered low. As such, radiation survey meters will not be used during the field investigation.

3.2.4 Environmental Hazards

The following paragraphs identify the potential hazards associated with flora and fauna at Former Warren AFB. If additional concerns are identified, they will be addressed in a HASP Addendum.

H:\_USACE_Omaha_20717\Windsorworkplans\DauGathering_nNAL\HASP\ACEHASPWPD 3-6 3.2.4.1 Hazardous Flora

Incidence of contact by individuals to poisonous/thorny plants is high; therefore, bare skin should be covered (i.e., long pants and long-sleeved shirt, steel toe boots, leather or cotton gloves, safety glasses, and head protection) as much as practical. Care should also be taken when walking in areas where uneven terrain may present a tripping hazard.

3.2.4.2 Hazardous Fauna

Mosquitoes and gnats pose a nuisance and physical hazard to field personnel; they distract workers, leading to accidents, and pose a physical threat by transmitting live microorganisms. Avoiding the use of perfumes and scented deodorants and donning light colored clothing is preferable. The use of Avon's Skin So Soft or other insect repellent is encouraged and will be provided on site.

There is a potential to come in contact with other dangerous insects; these include fire ants, chiggers, bees, wasps, hornets, mites, fleas, spiders, and ticks. Personnel should perform checks on each other periodically and at the end of the work shift. Insect bites must be reported to the SHSO.

Poisonous snakes such as the copperhead and rattlesnakes, known as pit vipers, as well as nonpoisonous snakes (i.e., black snakes) are common to this area. Snakes typically do not attack people but will bite when provoked, angered, or accidentally injured, as when stepped on. When encountering a snake, avoid quick, jerky motions, loud noises, and retreat slowly; do not provoke the snake. If bitten, follow procedures outlined in Section 8.5, Emergency Medical Treatment and Telephone Numbers.

Prior to initiating site activities, each individual shall be questioned as to any known sensitivities to the previously mentioned organisms or agents.

H \_USACE_Oraaha_20717\Windsonvorkplans\DataGathering_FINAL\HASP\ACEHASP WPD 3-7 3.2.5 Task-Specific Hazards

Listed below are summaries for the known or assumed hazards associated with each potential task for any one area. Levels of protection (outlined in the HASP) will be selected based on this task-specific hazard identification, information obtained from previous investigations and site visits, and previous experience with similar site investigations or activities.

3.2.5.4 IDW Management

Soil spoils and decontamination fluids generated during the advancement of the Geoprobe boring will be screened using a PID. If absent of VOCs, the soil will be placed back into the hole or at the burm location. If VOCs are detected or discoloring observed, the soil and decontamination fluid will be containerized in a plastic baggie or 5-gallon bucket, depending on the quantity generated. The containerized soil and decontamination fluid will be stored on site. Disposal of IDW will be dependent on the laboratory analytical results. IDW for these activities is expected to be very minimal. Purge water from water well sampling will be placed onto the ground surface.

3.2.6 Summary

The information provided in the previous section identified the potential hazards associated with the field activities to be performed at Site 12. This information is used to ascertain what levels of

H:\_USACE_Omaha_20717\Windsorworkplans\DataGath«ing_FINAL\HASI>\ACEHASP WPD 3-10 protection will be required for each field activity. In determining levels of protection for the HASP, the following items will be considered:

• Quantity of constituent that is available for absorption. • Exposure time that is available for absorption. • Frequency with which the exposure occurs. • Physical form of the constituents. • Presence of other constituents. • Toxicity of the constituents. • Ventilation, natural or otherwise. • Appropriate hygienic practices. • Protective equipment in use. HASP training.

Based upon this section and the information furnished in the previous two sections, the level of protection which will be assigned during the field activities is Level D+, as described in Section 6.0.

H \_USACE_Omaha_20717\Windsotworkplans\DalaC«thering_FINAL\HASP\ACEHASP WPD 3-11 4.0 SITE CONTROL

Measures need to be addressed in the HASP for managing the daily control (i.e., access, site conditions, etc.). The following subsections provide a discussion of each site control measure that will be consistent with site activities at Site 12.

4.1 Access

Access is the means by which personnel will enter a secured area. At Site 12, measures will be taken by Baker to ensure that these areas are controlled. The sections below outline the guidelines for these procedures.

4.2 Investigative Area

The Site Manager, in cooperation with USAGE - Omaha District, will be designated to coordinate overall access and security at Site 12.

• Personnel will not be permitted within the Work Zone (i.e., Exclusion Zone) or Contamination Reduction Zone (CRZ) without proper authorization from the SHSO.

Personnel arriving or departing the site will be documented in the site logbook.

• Activities on site must be cleared through the Site Manager and documented in the site logbook.

43 Site Conditions

Site conditions, as outlined below, will be or have been identified in the site-specific Work Plan.

• The prevailing wind • Anticipated weather conditions • Site topography

H :\_US ACE_Omaha_20717\Windsonvoricplans\DataGathering_FIN AL\HASP\ACEHASP. WPD 4-1 4.4 Work Zones

To reduce the accidental spread of hazardous substances by workers from a potentially contaminated area to a clean area, zones will be delineated to ensure that work activities and contamination are confined to the appropriate areas, and to keep unauthorized personnel from entering the work zones. The sections below identify the requirements, based on the level of protection in use.

4.4.1 Level C and B Activities

It is not anticipated that field activities will be conducted at these levels of protection, however, if necessary, zones for activities conducted under Level C or higher protection levels shall be established utilizing control boundaries between the Work Zone, the CRZ, and the Support Zone (i.e., Clean Zone). These boundaries shall be defined as follows:

• Work Zone - The area where the primary site investigation activity occurs.

Hotline - The boundary between the Work Zone and CRZ.

• CRZ - The area between the Work Zone and the Support Zone.

• Contamination Control Line - The boundary between the CRZ and the Support Zone.

• Support Zone - The outermost area next to the CRZ and upwind of the site investigative activities.

These boundaries will be marked using one or more of the following materials:

• Colored boundary tape, cones, or equivalent for the Hotline or the Decontamination Corridor of the CRZ.

• Barriers for the Contamination Control Line such as posted signs and/or barricades.

H:\_USACE_Omaha_20717\Windsorworkplans\DataGathering_FINAL\HASPUCEHASPWPD

4-2 4.4.2 Level D and D+ Activities

Zones for activities conducted under Levels D or D+ will be established according to the following guidelines.

4.4.2.1 Populated Areas

In populated areas, Work Zones for activities conducted under Level D or D+ protection levels shall be established in such a manner as to preclude unauthorized personnel from entering the investigative area. A boundary will be established to separate the Work Zone from the Support Zone using available materials such as, the Baker field vehicle, natural boundaries (e.g., buildings, structures, fences), or signs/placards, boundary tape, cones, barricades, etc.

4.4.2.2 Unpopulated/Secluded Areas

In unpopulated or secluded areas, the aforementioned materials may not be used due to the exclusive nature of the area, the short duration of the activity, and the low risk to outside populations. The SHSO and/or Field Team Leader will be responsible for making this determination.

4.5 "Buddy System"

Activities that involve hazards and/or the potential for contact with hazardous materials will be performed by a work team of no fewer than two people (i.e., Buddy System).

4.6 Safe Work Practices

Routine safe work practices consist of:

• Conducting operations in a manner to reduce exposure of personnel and equipment. • Implementing appropriate decontamination procedures. • Conducting sampling activities from an upwind location. Adherence to applicable safety regulations in OSHA Standards 29 CFR 1910 and 1926.

H \_USACE_Omaha_20717\Windsorworkplans\DataGalhering_FINAL\HASP\ACEHASP WPD 4-3 • Setting up barriers to exclude unauthorized personnel from contaminated areas. • Minimizing the number of personnel and equipment at the site. • Establishing work zones within the site. • Establishing control points for ingress to and egress from work zones.

4.7 Sanitation Requirements/Site Precautions

Provisions for sanitation requirements and precautions to be followed at each site, are outlined below. Due to the type of operations performed at the former Warren AFB, smoking will be permitted only in authorized areas. Temporary sanitary facilities will not be provided due to the short project duration. The former Warren AFB sanitary facilities (available to contractors) will be used as necessary.

A supply of clearly marked potable water, tightly closed.

• Clean wash water will be made available.

• Eating, drinking, chewing gum or tobacco, smoking, or any practice that increases the probability of hand-to-mouth transfer and ingestion of material, is prohibited in any area designated as contaminated. Smoking will be allowed only in areas designated areas. Hands and face must be thoroughly washed before breaking for meals and upon leaving the site. Contaminated work garments are not to be worn off-site.

• Whenever decontamination procedures for outer garments are in effect, the entire body should be thoroughly washed as soon as possible after the protective garment is removed.

• Facial hair that interferes with a satisfactory fit of the mask-to-face seal is not permitted on personnel that may be required to wear respirators.

• Contact with contaminated or potentially contaminated surfaces should be avoided. Wherever possible, do not walk through puddles, leachate, discolored surfaces, kneel on ground, lean, sit or place equipment on drums or containers.

H.\_USACE_Omaha_20717\Windsorworkplans\DalaGathering_FINAL\HASP\ACEHASP.WPD 4-4 Alcoholic beverages and firearms are prohibited on site.

Medicine and alcohol can potentiate the effects of exposure to toxic chemicals, therefore, prescribed drugs should only be taken by personnel when approved by a qualified physician. Alcoholic beverage intake should be minimized or avoided during after-hour operations.

Site personnel will observe any posted sign, warning, fence, or barrier posted around contaminated areas.

Site personnel must wear the proper attire while on site. At a minimum, this will include steel-toed boots, work pants (e.g., jeans, or other durable material), and work shirt (e.g., short or long-sleeve, made of a durable material). Tank tops, muscle shirts, and sweat pants are not permitted.

H:\_USACE_Omaha_20717\Windsonvorkplaiis\DauGathering_FIN AL\HASP\ACEHASP WPD 4-5 5.0 ENVIRONMENTAL MONITORING

It is anticipated that environmental monitoring will be performed at each site; the level and degree of monitoring will be addressed in this section of the HASP. Due to the duration and variability of field tasks only real-time air monitoring (versus integrated air monitoring) will be used to assess action levels. The action levels for the PID, as specified in Section 5.1, below are based on a worst- case 8-hour time weighted average-permissible exposure limit (PEL) of 1 part per million (ppm) (i.e., benzene, etc.), and are consistent with those listed by the USEPA in Section 6.9, of the Standard Operating Safety Guides (June. 1992). The paragraphs below identify general procedures that will be followed.

5.1 Personal Monitoring

Personal monitoring will be accomplished using real time environmental monitoring instrumentation directed at the breathing zone, which is defined as the area bordered by the outside of the shoulders and from the mid-chest to the top of the head, of work party personnel. Breathing Zone (BZ) monitoring will be performed each time a reading is taken at the point source (i.e., after well is opened for groundwater sampling, after breaking ground for soil sampling, etc.). A PID meter will be used to monitor for toxic vapors. A summary of air monitoring information is provided in the table below. The guidelines below identify the protection levels required according to the concentrations measured using each piece of equipment.

Monitoring Monitoring Location/ Monitoring Device Personnel Frequency Action Level Action PID Field Personnel Prior to and <5 meter units Level D during work (mu)* tasks 5 mu* Level C

>50 mu* Stop Work, Consult with PHSO Sustained levels above background for 5 minutes.

H:\_USACE_Ornaha_20717\Windsorworkplans\DataGathCTing_FINAL\HASP\ACEHASPWPD 5-1 5.2 Point Source Monitoring

Point source monitoring, which is monitoring performed at the source of the sampling/investigative activity (e.g., monitoring well, etc.), will comply with the action levels outlined below. Instrumentation to be used will include a PID.

PID

• If detecting levels greater than background, immediately measure the BZ levels following the action levels set forth in Section 5.1.

• For levels greater than 20 times the background level, retreat upwind, monitor BZ, and return after allowing source to aerate.

For levels that are sustained, contact the SHSO for guidance.

As work progresses, the scope of monitoring in the HASP may be extended based on monitoring results, odor detection, changing work conditions, and signs or symptoms of exposure. Any of these conditions will be immediately investigated and acted upon by the SHSO.

53 Perimeter Monitoring

Perimeter monitoring, which is defined as monitoring performed at borders beyond the Support Zone and often at the "fence line", will not be required for these field activities.

5.4 Specific Environmental Monitoring Equipment and Frequency

Monitoring equipment and frequency of monitoring for this field investigation have been identified previously in this HASP.

H:\_USACE_Omaha_207l7\Windsorworkplans\DataGallKring_FINAL\HASP\ACEHASPWPD 5-2 5.5 Equipment Maintenance and Calibration

Baker's procedures for the return of equipment to inventory and for maintenance of the equipment shall be followed in order to assure that the optimum level of operation is maintained for the item. Equipment calibration under the direction of the SHSO will be completed daily before use and calibration information entered onto the equipment calibration form. Note: Per USAGE, calibration at the end of the day also is required. Forms will be maintained on site for the duration of the project with copies to be given to the Equipment Manager once the equipment has been returned to the office. Procedures for equipment maintenance and calibration follow those guidelines found in the operating manual provided by the manufacturer which is included with each piece of equipment.

5.6 Monitoring Documentation

As environmental monitoring is performed, documentation of the results will be entered into the Field Logbook of the SHSO or other personnel performing the monitoring. Documentation will include the date, time, instrument result, general location, and specific location, such as point source, breathing zone, or area, and weather conditions during the monitoring time period. Copies of the field logbook will be maintained on-site until the end of the field activities, whereby the logbooks will become part of the permanent file.

H:\_USACE_Omaha_20717\Windsorworkplans\DataGathering_FINAL\HASP\ACEHASP. WPD 5-3 6.0 PERSONAL PROTECTIVE EQUIPMENT

Based on an evaluation of potential hazards at each area under investigation, the levels of protection and corresponding PPE will be designated for applicable field activities as discussed below. Upgrading or downgrading the level of protection will be based on real time monitoring, working conditions, and the discretion of the SHSO.

Note: No single combination of protective equipment and clothing is capable of protection against hazards. PPE should be used in conjunction with safe work practices, effective decontamination, and good personal hygiene.

Protective ensembles which may be necessary at the former Warren AFB Site 12 are described below:

Level of Protection Field Activity B C D+ D Other Mobilization/Demobilization X Potentiometric Surface Survey X UST Subsurface Soil Sampling X IDW Management X

Level D

Normal work clothes or coveralls Work gloves, cloth or leather (as needed) Steel toe boots Safety glasses Hard hat* only necessary during heavy equipment operations or overhead hazards

H:\_USACE_Omaha_20717\Windsorworkplans\DauGathering_FINAL\HASP\ACEHASPWPD 6-1 Modified Level D

• Work clothes • Chemical-Resistant Gloves • Steel toe boots • Safety glasses • Hard hat* only necessary during heavy equipment operations or overhead hazards

Level C (If up-grade in protection is needed)

• Air-purifying respirator, half-face, organic vapor/HEPA cartridges • Chemical-Resistant Gloves • Steel toe boots • Safety glasses

Except in emergency situations, changes to the specified levels of protection shall only be made with the approval of the SHSO and the Site Manager, in consultation with the PHSO, USACE Project Manager, and/or the Baker Project Manager.

6.1 Respiratory Protection

It is not anticipated that respiratory protection will be necessary during the field activities, however, for the sake of completeness in the event of an upgrade to the level of protection, the following are presented.

6.1.1 Level C

A NIOSH-certified half-face negative pressure Air-Purifying Respirator with an appropriate cartridge for use with the detected hazardous materials and the measured contaminant concentrations will be used at this level. Upgrades or downgrades in this level of respiratory protection will be based on measured "realtime" air contaminant concentrations as outlined in Section 5.0 of this HASP, and the SHSO's observations.

H:\_USACE_Ornaha_20717\Windsorworkplans\DatiiGatlKring_FINAL\HASP\ACEHASP.WPD 6-2 Cartridge changeover will occur when one or more of the following have been observed: exposure duration greater than for vapor/gas cartridges; increase in breathing resistance; a noticeable odor or taste; eye or throat irritation; and other indicators such as end-of-service life indicators for specialty filter cartridges.

6.1.2 Level D+

A NIOSH-certified negative pressure air-purifying respirator, meeting the requirements identified under Level C, will remain on standby at this level.

6.2 Care and Cleaning of Personnel Protective Equipment

Provisions for the care and cleaning of PPE used on site are outlined in the Baker Safety SOPs presented in Attachment C.

H:\_USACE_Omaha_207I7\WindsorworlipUns\DataGahcriiig_nNAL\HASP\ACEHASPWPD 6-3 7.0 DECONTAMINATION PROCEDURES

Procedures to be followed for the decontamination of personnel and equipment, as well as handling of materials generated during decontamination, are discussed in the following sections.

7.1 Personnel Decontamination

Personnel leaving the Work Zone will be thoroughly decontaminated. It is not anticipated that all of these levels of protection will be necessary for the field activities to be performed at the former Warren AFB, however, for completeness in the event that levels of protection are upgraded in the field, Levels D+, and C are presented. The following protocol will be used for the decontamination stations according to levels of protection assigned to a field investigation task:

Level D+ Level C 1. Equipment drop 1. Equipment drop 2. Glove removal and disposal 2. Respirator removal 3. Hand/face wash 3. Glove removal/disposal 4. Equipment cleaning 4. Hand/face wash 5. Respirator cleaning/sanitizing 6. Equipment cleaning

The following decontamination equipment is required for Level C and higher protection levels and recommended for Level D+ protection:

• Towels • Contaminated clothing disposal bag or drum Respirator cleaning wipes (Level C) • Liquinox and water as the decontamination solution • Rinse water

The decontamination liquids generated during the advancement of the Geoprobe boring will be screened using a PID. If absent of VOCs, the fluid will be placed in the borehole or on the ground surface adjacent the borehole. If VOCs are detected in the fluid or in the soil, the fluid will be

H:\_USACE_Omaha_20717\Windsorworkplans\DauGathering_FINAL\HASP\ACEHASP.WPD

7-1 containerized in a 5-gallon bucket. The containerized IDW will be stored on site. Disposal of IDW will be dependent on the laboratory analytical results. Disposable PPE and sampling equipment will be placed in plastic bags and disposed as municipal waste.

7.2 Effectiveness of Personnel Decontamination

The effectiveness of site decontamination methods will be evaluated by the SHSO on a periodic basis. This evaluation may include the observation of personnel decontamination, inspection of PPE before use and after decontamination, and questioning site personnel for signs and symptoms of exposure. Additional measures may also be employed by the SHSO at their discretion.

73 Equipment Decontamination

Provisions for the decontamination of equipment will be based on the size and type of equipment used. Specific decontamination procedures for the former Warren AFB can be found in the Work Plan.

7.4 Decontamination Materials

The protocols outlined in the Work Plan for the handling of materials used for decontamination such as packaging, storing, and disposing, will be followed to: (1) minimize the risk of off-site exposures that could endanger public health; and (2) limit the potential for liabilities associated with handling, containment, storage, and transportation of contaminated materials. These protocols comply with Baker's procedure for IDW management which are outlined in the Work Plan.

H \_USACE_Omaha_20717\Windsonvortcplans\DataGalhering_FINAl-\HASP\ACEHASP WPD 7-2 8.0 EMERGENCY PROCEDURES

The activities to be conducted at the former Warren AFB that fall under this HASP are not remediation (i.e., cleanup), but investigative; therefore, the potential for a "release" to air, water, or soil is low. However, other emergencies, such as fire or personnel injury may occur. If so, local emergency response groups will be called in to handle the incident, as necessary.

8.1 Pre-Emergency Planning

Due to the scheduled field activities being followup to the RJ work and not involving heavy machinery and subsurface investigations, Baker will not contact the applicable emergency response personnel to brief them on site activities and hazards. However, if the scope changes, the PHSO may require contacting the applicable emergency response personnel. If so, during mobilization activities, Baker will contact applicable emergency response personnel; the information discussed may include:

These personnel will also be familiar with Baker's program for potential exposure to bloodborne pathogens as outlined in the Baker Safety SOPs presented in Attachment C. Subcontractors will be responsible for securing proper medical attention for their employees. Baker may assist the subcontractor as necessary.

8.7.1 Physical Injury

If an employee working in a contaminated area is physically injured, first aid procedures will be followed. If the employee can be moved, the individual will be taken to the edge of the work area and decontaminated, if necessary. Emergency first aid may be administered by Baker personnel prior to transporting to an awaiting ambulance or to a local emergency medical facility, as appropriate.

H:\ USAGE Omaha_207l7\Windsorworkplans\DataGathcring_FINAL\HASPV\CEHASP WPD 8-6 8.7.2 Chemical Injury

If the injury to a worker is chemical in nature (e.g., direct contact or exposure), the following first aid procedures will be instituted immediately:

• Eye Exposure - If contaminated solid or liquid gets into the eyes, wash the eyes immediately at the 15-minute emergency eyewash station or with the personal eye wash bottle when an eye wash station is not immediately available. Obtain medical attention immediately.

• Skin Exposure - If contaminated solid or liquid gets on the skin, promptly wash the contaminated skin using soap or mild detergent and water. If solids or liquids penetrate through the clothing, remove the clothing immediately and wash the skin using soap or mild detergent and water. Obtain medical attention immediately.

• Swallowing - If contaminated solid or liquid has been swallowed immediately contact the Poison Information Services at (800) 955-9119. Do not induce vomiting in an unconscious person. Obtain medical attention as directed by the Poison Information Center.

• Breathing - If a person has difficulty breathing, move the exposed person to fresh air at once. If breathing is not evident, check for pulse and perform appropriate first aid, either rescue breathing or CPR, depending on the condition. Obtain medical attention immediately.

8.73 Snakebite Injury

In the event of a snakebite injury, the following procedures will be followed.

Look for signs and symptoms such as the characteristic appearance of two small holes, usually about a half inch apart, with surrounding discoloration, swelling, and pain. Systemic signs, which may or may not occur, include weakness, sweating, faintness, and signs of shock.

H:\_USACE__Omaha_20717\Windsorworkplans\DataGathering_FIN AIAHASPVACEHASP. WPD 8-7 1. Provide treatment as follows:

2. Calm the victim and keep affected area still.

3. Contact ambulance if you cannot provide victim with transportation to the nearest hospital.

4. Wash the wound.

5. Keep the affected area below the level of the heart if bite is on the arm or leg. Treat for shock.

6. Monitor airway, breathing, and circulation.

7. Obtain physical description of snake, if possible.

8. Provide the emergency medical responder, either the ambulance attendant or the emergency room at the hospital, with pertinent information such as: how long ago the bite occurred, the type of snake (if known), any known allergic conditions (if known), etc.

9. Inform the SHSO as soon as possible.

8.7.4 Spider Bite Injury

There are two spiders commonly found in the United States whose bite can be serious: the black widow spider and the brown recluse spider. These bites may be serious, even life-threatening. Many other spiders will bite, but they do not produce serious complications. The black widow spider measures approximately 1 inch long with its legs extended. It is glossy black in color and has a distinctive yellow-orange marking in the shape of an hourglass on its belly. On its back, however, there is no marking, and unless you happen to turn the spider over, you cannot see this mark. The danger of the black widow spider bite lies in its systemic manifestations. The venom from this

H:\_USACE_Onaha_20717\Windsorworkplans\DataGathering_FINAL\HASPUCEHASP.WPD 8-8 spider attacks the nervous system, resulting in severe muscle cramps with boardlike rigidity of the abdominal muscles, tightness in the chest, and difficulty in breathing. Sweating, nausea, and vomiting will also occur.

The emergency treatment for the black widow spider bite is basic life support. Sometimes the individual is not even aware of having been bitten, or where. Apply cold to the site of the bite if it can be identified. There is a specific antivenom for this spider bite that must be administered by a physician. It is particularly important to identify the spider, and bring it in, if you can.

The brown recluse spider is a little bit smaller than the black widow spider and is dull brown in color. It has a violin-shaped mark on its back, which can be seen when you are looking at the spider from above. The spider gets its name because it tends to live in dark areas, corners, and old unused buildings. The bite from this animal produces local rather than systemic manifestations. The venom of the brown recluse spider causes severe local tissue damage and can lead to an ulcer and gangrene. The bitten area becomes red, swollen, and tender within a few hours after the bite. A small blister forms, and several days later, this may form a large scab, covering a deep ulcer. Death is rarely reported, but these bites need local surgical treatment, and these patients should be brought to the hospital. Again, if possible, identification of the spider should be carried out.

8.8 Emergency Decontamination Procedures

In the event of a medical emergency, patients will be adequately decontaminated before transfer, if possible, to prevent contamination of the medical transport vehicle and medical facility. Emergency personnel decontamination will include the following, depending on the level of protection.* As stated previously, it is not anticipated that all levels of protection will be necessary, however, for the sake of completeness in the event that levels of protection are upgraded, the following have been included.

Level D+ Level C • Equipment drop • Equipment drop • Respirator removal • Glove removal

H:\_USACE_Oraaha_20717\WindsonvorkpUns\DataGathcring_FIN/a.\HASP\ACEHASPWPD 8-9 • If circumstances dictate that contaminated clothing cannot be readily removed, then remove gross contamination and wrap injured personnel with clean garments or blankets to avoid contaminating other personnel or transporting equipment. Emergency personnel are to be immediately informed of the injured person's condition and potential contaminants and provided with pertinent chemical data.

If necessary, one of the site personnel equipped with appropriate PPE may accompany the injured worker and perform decontamination with supervision of medical personnel.

8.9 Personal Protection and First Aid Equipment

PPE available for emergency response will include the following:

• Nitrile gloves • Safety glasses and goggles • Half-face cartridge respirators

PPE and first aid equipment will be available in the support zone (i.e., Baker vehicle). The following emergency and first aid equipment will be located at the site:

• Fire Extinguisher • First aid kit • Personal eye wash bottle

8.10 Notification

8.15 Spill Containment Procedures

In the event that a small (less than the reportable quantity), easily-controlled spill of hazardous substances (e.g., gasoline, oil, etc.) occurs during the implementation of field activities, spill containment will be utilized to prevent the additional migration of contaminants through the site area. Any release to soils or surface waters equaling or exceeding the reportable quantities under CERCLA or the USEPA Clean Water Act will be reported to appropriate USAGE - Omaha District personnel, who in turn will notify the appropriate authorities.

H:\_USACE_Omalia_20717\WindsorworkpUns\DalaGalhering_FlNAL\HASP\ACEHASP. WPD 8-14 Specific spill containment procedures will be dependent on the type of materials spilled and the type of environment affected. Potential spill containment procedures may include diking and removal or containment of the contaminated materials.

8.16 Emergency Reporting

Injury reports will be completed for any accidents no matter how minor the injury might appear. Injuries resulting from treatment other than first aid will be reported to the Project Manager. Appropriate reporting and record keeping forms for Baker personnel will be completed by the Project Manager and will be submitted to Baker Human Resources (Supervisor's Accident Report Form, Attachment B). Additionally, the USAGE Project Manager will be notified according to EM383-1-1.

A copy of site personnel training records will be maintained at Baker's Coraopolis, PA office. At minimum, this will include a copy of each individual's 40-hour and most recent 8-hour training certificates, HASP training record, supervisory training certificate (if, applicable), American Red Cross Standard First Aid, and respirator fit-test records.

H \_USACE_Omaha_20717\Windsorworkpians\Da«Gatbcring_FINAL\HASP\ACEHASP WPD 9-3 10.0 MEDICAL SURVEILLANCE REQUIREMENTS

10.1 General

The medical surveillance program, for initial and annual exams, conducted for Baker employees is included in Attachment C. Personnel who may be exposed to materials having potentially adverse and deleterious health effects, obtain medical clearance from Baker's Board Certified Occupational Health Physician in accordance with 29 CFR 1910.120(f) prior to entry onto any site. Baker's corporate medical surveillance program establishes a medical baseline and monitors for symptoms of overexposure for individuals who participate in Preliminary Assessments, Site Inspections, Remedial Investigations, Feasibility Studies, and construction-phase services at sites covered by the Department of Labor, OSHA, Hazardous Waste Operations and Emergency Response Standard, 29 CFR 1910.120. The program will include a medical and work history and is intended to determine the individual's capability for performing on-site work, including wearing chemical protective clothing and respiratory protective equipment in a thermally-stressed environment.

Baker employees that will be engaged in site activities covered by the 29 CFR 1910.120 standard receive a Group III physical examination by a licensed physician who has provided information on the individual's site activities and exposure or anticipated exposure levels. This exam is received initially upon hire, then once every 12 months thereafter. More frequent medical examinations, consultations, and or laboratory testing will be provided if the occupational health physician determines that an increased frequency of examination is required. A complete Group III medical exam includes parameters such as height, weight, vision, temperature, blood pressure, and a complete review of occupational and medical histories. Other tests in a Group III exam include chest x-rays, electrocardiogram, spirometry, urinalysis, and blood tests.

A table describing the medical surveillance testing parameters performed annually on Baker employees will be available upon request. The need for additional monitoring depending on site conditions will be evaluated on a case-by-case basis.

H \_USACE_Omaha_20717\Windsonvorkplans\DauGathcring_FINAL\HASP\ACEHASP.WPD 10-1 10.2 Site-Specific

Prior to entry onto the site, personnel, will be required to provide medical clearance to the Project Manager from their company physician in accordance with 29 CFR 1910.120(f), stating that they are physically capable of performing the activities required of them. The need for additional monitoring, dependent on information obtained during the site characterization, will be evaluated on a case-by-case basis. However, in the event that site employees are injured, receive a health impairment, develop signs or symptoms which may have resulted from exposure to hazardous substances resulting from an emergency incident, or are exposed during an emergency incident to hazardous substances at concentrations that are or may be above the permissible exposure limits or the published exposure levels without the necessary personal protective equipment being used, medical examinations and or consultations shall be performed according to the following schedule:

1. As soon as possible following the emergency incident or development of signs or symptoms.

2. At additional times, if the examining physician determines that follow-up examinations or consultations are medically necessary.

Although it has a flash point of 90 F, TCE bums with difficulty. For small fires, use dry chemical, carbon dioxide, water spray, or regular foam. For large fires, use water spray, fog, or regular foam. Unusual Fire or Explosion Hazards: Vapor/air mixtures may explode when ignited. Container may explode in heat of fire. Special Fire-fighting Procedures: Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus (SCBA) with a full facepiece operated in pressure-demand or positive-pressure mode. Structural firefighters' protective clothing provides only limited protection against TCE. Apply cooling water to sides of container until well after fire is out Stay away from ends of tanks. Do not release runoff from fire control methods to sewers or waterways. Section 5. Reactivity Data Stability/Polymerization: TCE slowly decomposes in the presence of light and moisture to form corrosive hydrochloric acid. Hazardous polym- erization cannot occur. Chemical Incompatibilities: Include alkalis (sodium hydroxide), chemically active metals (aluminum, beryllium, lithium, magnesium, sodium, potassium, and titanium), epoxides, and oxidants (nitrogen tetraoxide, perchloric acid). Contact with l-chloro-2^-epoxy propane or the mono and di 23-epoxypropyI ethers of 1,4-butanediol + 2^-bis-4(2',3'-epoxypropoxy)-phenylpropane can, in the presence of catalytic quantities of halide ions, cause dehydrochlorination of TCE to explosive dichloroacetylene. Conditions to Avoid: Exposure to light, moisture, ignition sources, and incompatiblcs. Hazardous Products of Decomposition: Thermal oxidative decomposition of TCE (above 300 C) or exposure to ultraviolet light can produce carbon dioxide (CO2) and toxic dichloro acetylene (explosive), chlorine, hydrogen chloride, and phosgene gas. Section 6. Health Hazard Data Carcinogenicity: The following agencies have rated TCE's carcinogenicity: IARC (Class 3, limited animal evidence & insufficient human data), Germany MAK (Class B, justifiably suspected of having carcinogenic potential), & NIOSH (Class X, carcinogen defined with no further categor- ization). Summary of Risks: TCE vapor is irritating to the eyes, nose, and respiratory tract and inhalation of high concentrations can lead to severe CNS effects such as unconsciousness, ventricular anythmias, and death due to cardiac arrest. Mild liver dysfunction was also seen at levefc high enough to produce CNS effects. Contact with the liquid is irritating to the skin and can lead to dermatitis by detailing the skin. Chronic toxicity is observed in the victims increasing intolerance to alcohol characterized by 'degreasers flush', a transient redness of the face, trunk, and arms. The euphoric effect of TCE has led to craving, and habitual sniffing of its vapors. _ Continue on next page

Continued TCE crosses the piacental barrier and thos exposes the fetus (any effects are yet unknown). There are increased reports of menstrual disorders in women workers and decreased libido in males at exposures high enough to cause CNS effects. TCE is eliminated unchanged in expired air and as metabolites (trichloroacetic acid & tricbJoroethanol) in blood and urine. Medical Conditions Aggravated by Long-Tenn Exposure: Disorders of the nervous system, skin, heart, liver, and kidney. Target Organs: Respiratory, central & peripheral nervous, and cardiovascular (heart) systems, liver, kidney, and skin. Primary Entry Routes: Inhalation, skin and eye contact, and ingestion (rarely). Acute Effects: Vapor inhalation can cause eye, nose, and throat irritation, nausea, blurred vision, overexcitement, headache, drunkenness, memory loss, irregular heartbeat (resulting in sudden death), unconsciousness, and death due to cardiac failure. Skin contact with the liquid can cause dryness and cracking and prolonged exposure (generally if the victim is unconscious) can cause blistering. Eye contact can cause irritation and watering, with comeal epithelium injury in some cases. Ingestion of the liquid can cause lip, mouth, and gastrointestinal irritation, irregular heartbeat, nausea and vomiting, diarrhea (possibly blood-stained), drowsiness, and risk of pulmonary edema (fluid in lungs). Chronic Effects: Effects may persist for several weeks or months after repeated exposure. Symptoms include giddiness, irritability, headache, digestive disturbances, mental confusion, intolerance to alcohol (degreasers flush), altered color perception, loss or impairment of sense of smell, double vision, and peripheral nervous system function impairment including persistent neuritis, temporary loss of sense of-touch, and paralysis of the fingers from direct contact with TCE liquid. FIRST AID Eyes: Do not allow victim to rub or keep eyes tightly shut Gently lift eyelids and flush immediately and continuously with flooding amounts of water until transported to an emergency medical facility. Consult a physician immediately. Skin: Quickly remove contaminated clothing. Rinse with flooding amounts of water for at least 15 min. Wash exposed area with soap and water. Inhalation: Remove exposed person to fresh air and support breathing as needed. Ingestion: Never give anything by mouth to an unconscious or convulsing person. Contact a poison control center and unless otherwise advised, have that conscious and alert person drink 1 to 2 glasses of water, then induce vomiting. Do not give milk, as its fat content (TCE is lipid soluble) may inhance gastrointestinal absorption of TCE. Note to Physicians: TCE elimination seems to be triphasic with half lives at 20 min, 3 hr, and 30 hr. Some success is seen in treating patients with propranolol, atropine, and disulfiram. Monitor urine and blood (lethal level = 3 to 110 pg/mL) metabolites. BEI =100 mg/g creatinine (trichloroacetic acid) hi urine, sample at end of workweek. BEI = 4 mg/L (trichioroethanol) in blood, sample at end of shift at end of the -workweek. These tests are not 100% accurate indicators of exposure; monitor TCE in expired air as a confirmatory test Section 7. Spill, Leak, and Disposal Procedures Spill/Leak: Immediately notify safety personnel, isolate and ventilate area, deny entry, and stay upwind. Shut off all ignition sources. For small spills, take up with earth, sand, vermiculite, or other absorbent, noncombustible material and place in suitable container for later disposal. For large spills, flush to containment area where density stratification will form a bottom TCE layer which can be pumped and containerized. Report any release in excess of 1000 Ibs. Follow applicable OSHA regulations (29 CFR 1910.120). Ecotoxichy Values: Bluegill sunfish, LCso = 44,700 {jg/L/ 96 hr; fathead minnow (Pimephales promelas), LCjo = 40.7 mg/L/96 hr. Environmental Degradation: In air, TCE is photooxidized with a half-life of 5 days and reported to form phosgene, dichloroaceryl chloride, and formyl chloride. In water it evaporates rapidly in minutes to hours. TCE rapidly evaporates and may leach since it does not absorb to sediment Soil Absorption/Mobility: TCE has a Log K^ of 2, indicating high soil mobility. Disposal: Waste TCE can be poured on dry sand and allowed to vaporize in isolated location, purified by distillation, or returned to supplier. A potential candidate for rotary kiln incineration at 1508 to 2912 F (820 to 1600 C) with an acid scrubber to remove halo acids.

Special Protection Data Goggles: Wear chemical safety goggles (cup-type or rubber framed, equipped with impact-resistant glass), per OSHA eye- and face-protection regulations (29 CFR 1910.133). Because contact lens use in industry is controversial, establish your own policy. Respirator Seek professional advice prior to respirator selection and use. Follow OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear a MSHA/NIOSH- approved respirator. At any detectable concentration, wear a SCBA with a full facepiece operated in pressure demand or other positive pressure mode. For emergency or nonroutine operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning! Air-purifying respira- tors do not protect workers in oxygen-deficient atmospheres. If respirators are used, OSHA requires a respiratory protection program that includes at least medical certification, training, fit-testing, periodic environmental monitoring, maintenance, inspection, cleaning, and convenient, sanitary storage areas. Other: Wear chemically protective gloves, boots, aprons, and gauntlets made from Viton or Neoprene to prevent skin contact Do not use natural rubber or polyvinyl chloride (PVC). Ventilation: Provide general and local exhaust ventilation systems to maintain airborne concentra- tions below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by control- ling it at its source/103' Safety Stations: Make available in the work area emergency eyewash stations, safety/quick-drench showers, and washing facilities. Contaminated Equipment: Separate contaminated work clothes from street clothes and launder before reuse. Remove this material from your shoes and clean personal protective equipment Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene especially before eating, drinking, smoking, using the toilet, or applying cosmetics. Section 9. Special Precautions and Comments Storage Requirements: Prevent physical damage to containers. Store in steel drums, in a cool, dry, well-ventilated area away from sunlight, heat, ignition sources, and incompatiblcs (Sec 5). Store large quantities in galvanized iron, black iron, or steel containers; small amounts in dark (amber) colored glass bottles. Engineering Controls: To reduce potential health hazards, use sufficient dilution or local exhaust ventilation to control airborne contaminants and to maintain concentrations at the lowest practical level. Design processes so that the operator is not directly exposed to the solvent or its vapor. Do not use open electric heaters, high-temperature processes, arc-welding or open flames in TCE atmospheres. Adminis- trative Controls: Consider preplacement and periodic medical exams of exposed workers with emphasis on skin, respiratory, cardiac, central and peripheral nervous systems, and liver and kidney function. Employ air and biological monitoring (BEIs).

Carcinogenicity: Neither the NTP, 1ARC, nor OSHA lists 1,2-dichloroethytene as a carcinogen. ~~~ ~ Summary of Risks: 1,2-Dichloroethylene's most important effect is its initation of the central nervous system (CNS) and narcosis. This material is toxic by inhalation, ingestion, and sirin contact It is also irritating to the eyes. The trans-isomer at 2200 ppm causes nausea, vertigo, and burning of the eyes. The trans-isomer is twice as potent as the cis-isomer. If renal effects occur, they are transient. Medical Conditions Aggravated by Long-Term Exposure: None reported. Target Organs: Central nervous system, eyes, respiratory system. Primary Entry Routes: Inhalation, ingestion, ?fr"» and eye contact Acute Effects: Inhalation of 1^-dichloroethylene causes narcosis, respiratory tract irritation, nausea, vomiting, tremor, weakness, central nervous depression, and epigastric (the abdomen's upper midregion) cramps. Contact with the liquid causes eye and skin (on prolonged contact) irritation. Ingestion causes slight depression to deep narcosis. Chronic Effects: None reported. FIRST AID Eyes: Flush immediately, including under the eyelids, gently but thoroughly with flooding amounts of running water for at least 15 min. Skin: Quickly remove contaminated clothing. After rinsing affected skin with flooding amounts of water, wash it with soap and water. Inhalation: Remove exposed person to fresh air and support breathing as needed. Have trained personnel administer 100% oxygen, preferably with humidification. Ingestion: Never give anything by mouth to an unconscious or convulsing person. If ingested, have a conscious person drink 1 to 2 glasses of water, then induce repeated vomiting until vomit is clear. After first aid, get appropriate in-plant, paramedic, or community medical support. Physician's Note: Intravenous injections of calcium gluconate may relieve cramps and vomiting. Treat central nervous system effects sympto- matically. Section 7, Spill, Leak, and Disposal Procedures Spill/Leak: Design and practice a 13-dichloroelhylene spill control and countemeaswe plan (SCCP). Notify safety personnel, remove all heat and ignition sources, evacuate hazard area, and provide adequate ventilation. Cleanup personnel should protect against vapor inhalation and skin or eye contact Absorb small spills on paper towels. After evaporating the 1,2-dichloroethylene from these paper towels in a fume hood, burn the paper in a suitable location away from combustible material. Collect and atomize large quantities in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device. Follow applicable OSHA regulations (29 CFR 1910.120). Disposal: Contact your supplier or a licensed contractor for detailed recommendations. Follow applicable Federal, state, and local regulations.

Inspection

Proper inspection of personal protective equipment (PPE) features several sequences of inspection depending on articles of PPE and ifs frequency of use as follows:

Inspection and operational testing of PPE received from the factory or distributor

Inspection of PPE as it is issued to workers

Inspection after use or training, and prior to maintenance

Periodic inspection of stored equipment

Periodic inspection when a question arises concerning the appropriateness of the selected equipment, or when problems with similar equipment arise

The primary inspection of PPE in use for activities at the site wfll occur prior to immediate use, wfll be conducted by the user to ensure that the specific device or article has been checked-out by the user, and that the user is familiar with its use.

Inspection Checklists

For protective clothing before use:

Determine that the clothing material is correct for the specified task

Visually inspect for imperfect seams, non-uniform coating, tears, and malfunctioning closures

Hold up to light and check for pinholes STANDARD OPERATING PROCEDURES FOR RESPD3ATORY PROTECTION DEVICES

Cleaning and Disinfecting Air Purifying Respirators .(APRs)

APRs in routine use wifl be deaned and disinfected at least daily. Where respirators are used occasionally, or when they are in storage, the respirators will be deaned after each use and thoroughly inspected prior to each subsequent use.

The steps for cleaning and disinfecting APRs daily follow:

Respirator disassembly. Respirators are taken to a dean location •where the filters, cartridges, or canisters are removed; damaged to prevent reuse; and discarded. For thorough deaning, the inhalation and exhalation valves, speaking diaphragms, and hoses are removed.

Cleaning. la most instances, the deaning and disinfecting solution provided by the manufacturer is used, and is dissolved in warm water in an appropriate deaning container or tub.: Using gloves, the respirator is placed in the solution, and swirled for a few moments. A soft brush-may be used to dean stubborn soiling.

Rinsing. The deaned and disinfected respirators are rinsed thoroughly in dean, warm water to remove all traces of detergent and disinfectant This step is very important in the prevention of contact dermatitis.

Drying. Respirators wifl be air dried on a dean surface. Drying with a soft doth to remove water spots (particularly around inhalation and exhalation valves and valve seats) is permitted.

Reassembly and Inspection. Clean, dry respirator facepieces should be re- assembled and inspected in an area separate from the disassembly area to avoid contamination of dean respirators. Special emphasis should be given to inspecting the respirators for detergent of soap residue left by inadequate rinsing. This appears most - often on valve seats and can cause valve leakage and/or sticking.

1 Don the respirator, and perform negative and positive pressure fit tests.

Storage of Respirators

Respirators wfll be stored in dean, secure areas which minimize the chance for contamination or unsanitary conditions. Respirators will be stored in dean, ziplock bags (or equivalent); and will be placed in position that wDl not distort the facepiece.

OSHA requires protection from the .following elements during storage of respirators:

PERSONAL PROTECTIVE EQUIPMENT (PPE) PROGRAM

1.0 INTRODUCTION

The objective of the Personal Protective Equipment ( PPE) Program is to protect employees from risk of injury or death by creating a barrier against workplace hazards. PPE is not a substitute for good engineering or administrative controls or good work practices, but should be used in conjunction with these controls to ensure the safety and health of employees. This program addresses eye, face, head, foot, hand and body protection in accordance with 29 CFR 1910.132. Separate programs exist for respiratory and hearing protection.

Federal OSHA standards require that employers perform a hazard assessment of the workplace to determine the nature of the hazards and ensure that appropriate PPE is available to employees. The standards require that employees be trained in the proper use, care and limitations of PPE.

2.0 SCOPE

The scope of this program is to specify the PPE requirements of Baker Environmental, Inc (Baker), which include:

Types of PPE available PPE inspection procedures Guidelines for specifying the appropriate PPE

3.0 RESPONSIBILITIES

This program includes the responsibilities of the Baker Health and Safety Coordinator, Project Manager, Site Manager, Site Health and Safety Officer (SHSO), and employees. The responsibilities of these individuals are presented in the Responsibilities section of this manual. Additional responsibilities are outlined below.

The Project Manager and Site Manager are responsible for ensuring that a hazard assessment is conducted and the specified PPE is provided and used by site personnel. The SHSO's duties include:

Issuing appropriate PPE Removing and replacing defective or damaged equipment

4.0 PROCEDURES

A Hazard Assessment Determination of each project is conducted to determine the nature of hazards that may be present and the selection of appropriate PPE requirements. Specifics of the hazard assessment conducted by Baker are presented in the site-specific health and safety plans. Revision No.: 0 Date: February 1997 Page 3 of4

4.1 Protective Equipment

The various types of PPE available is discussed in this section.

4.1.1 Eye and Face Protection

Eye and face protective equipment is required by OSHA where there is a reasonable probability of preventing injury when such equipment is used. Employers must provide a type of protector suitable for work to be performed and employees must use the protectors. These stipulations also apply to all personnel on site and include visitors while they are in hazardous areas.

Suitable protectors will be used when employees are exposed to hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation. Side protectors will be used when there is a hazard from flying objects. Goggles will be used when there is a hazard from chemical splashes. Equipment fitted with appropriate filter lenses will be used to protect against light radiation. Eye and face protectors will meet all provisions contained in the ANSI standard (ANSI Z87.1-1989).

For employees who wear prescription lenses, eye protectors will either incorporate the prescription in the design or fit properly over the prescription lenses.

4.1.2 Head Protection

Protective hats will be worn when hazards from falling or fixed objects, or electrical shock are present. Protective hats will meet all provisions contained in the ANSI standard (ANSI Z89.1-1969).

4.1.3 Foot Protection

Safety shoes will be worn when falling, rolling, puncture, or electrical hazards are present. Safety shoes will meet all provisions contained in the ANSI standard (ANSI Z41.1-1967).

4.1.4 Hand Protection

Suitable gloves will be worn when hazards from chemicals, cuts, lacerations, abrasions, punctures, bums, and harmful temperature extremes are present. Glove selection will be based on performance characteristics, conditions, duration of use, and hazards present

4.1.5 Dermal Protection

Suitable protective clothing will be worn when hazards from chemicals, cuts, lacerations, abrasions, punctures, bums, and harmful temperature extremes are present. Material/fabric selection will be based on performance characteristics, conditions, duration of use, and hazards present. Revision No.: 0 Date: February 1997 Page 4 of4

For additional information on specific types and classes of PPE, see Appendix A, General Guidelines for Choosing Personal Protective Equipment

4.2 Cleaning/Disposal

PPE will be cleaned or disposed in accordance with the Project specific Health and Safety Plan and applicable local/state/federal regulation. Non disposable PPE is not to be shared between employees until it has been properly cleaned and sanitized. Disposable PPE is not to be shared between employees.

5.0 TRAINING

Personnel training and record keeping requirements are presented in this section.

5.1 Personnel Training

Baker employee PPE training will be conducted during the 40-hour OSHA training and updated during the mandatory 8-hour annual refreshers. In addition, PPE training will be conducted during project related on-site health and safety briefings. The training will include, but not necessarily be limited to, the following subjects:

When, and where, PPE is necessary to be worn What PPE is necessary How to properly don, doff, adjust, and wear PPE The limitations of the PPE The proper care, maintenance, useful life and disposal of the PPE Demonstration that the employee understands the training material and is able to use PPE properly

5.2 Record Keeping

Written records of OSHA mandated training will be kept of the names of persons trained, the type of training provided, and the dates when training occurred. The records will be maintained in the employees permanent file. Project specific training will be recorded in the Project File. Original Training Certificates will be presented to the employee. APPENDIX A GENERAL GUIDELINES FOR CHOOSING PERSONAL PROTECTIVE EQUIPMENT

Table of Contents

1.0 Eye Protection 2.0 Head Protection 3.0 Feet Protection 4.0 Hand Protection 5.0 Dermal Protection

A-1 1.0 Eye PROTECTION

Protective eye wear is required when flying particles, dusts, fumes, vapors or harmful rays could expose an employee to potential eye injury.

1.1 Safety Glasses

Standard safety glasses look very much like normal glasses, but are designed to protect against flying particles. Safety glasses have lenses that are impact resistant and frames that are far stronger than regular eyeglasses. Safety glasses must meet the standards of the American National Standards Institute (ANSI). Safety glasses are also available in prescription form for those persons who need corrective lenses. Safety glasses can be equipped with side shields, cups, or tinted lenses to offer additional protection.

1.2 Safety Goggles

Like safety glasses, goggles are impact resistant and are available in tinted lenses. Goggles should provide a secure shield around the entire eye area to protect against hazards coming from many directions. Goggles are provided on project sites when a potential of chemical splashing exists and/or at the request of any site personnel.

2.0 HEAD PROTECTION

Head injuries can be caused by falling or flying objects, or by bumping the head against a fixed object. Head protectors, in the form of protective hats, must resist penetration and absorb the shock of a blow. The shell of the protective hat should be hard enough to resist the blow and the headband and crown straps should keep the shell away from the wearer's skull. Protective hats can also protect against electrical shock. Protective hats are made in the following types and classes:

Type 1 - helmets with a full brim, not less than 1 and 1/4 inches wide Type 2 - brimless helmets with a peak extending forward from the crown

For industrial purposes, three classes are recognized:

Class A - general service, limited voltage protection; Class B - utility service, high-voltage helmets; and • Class C - special service, no voltage protection.

3.0 FOOT PROTECTION

Footwear requirements on Baker projects must meet established safety standards. This is located by checking for the American National Standards Institute (ANSI) label inside each shoe.

A-2 3.1 Steel-Reinforced Safety Shoes

These shoes are designed to protect an employee's feet from common machinery hazards such as falling or roiling objects, cuts, and punctures. The entire toe box and insole are reinforced with steel, and the instep is protected by steel, aluminum, or plastic materials. Safety shoes are also designed to insulate against temperature extremes and may be equipped with special soles to guard against slips, chemicals, and/or electrical hazards.

3.2 Safety Boots

Baker requires the use of safety boots by Baker employees when splash or spark hazards (chemicals, molten materials) are present This includes the following:

« When working with corrosives, caustics, cutting oils, and petroleum products, neoprene or nitrile boots or similar are required to prevent penetration.

• When working with electricity, special electrical hazard boots which are designed with no conductive materials other than the steel toe (which is properly insulated).

4.0 HAND PROTECTION

When protective hand wear is required for job performance, the gloves must fit well, are comfortable to wear, and are rated to guard against the particular hand hazards present.

The following is a guide to the most common types of protective work gloves and the types of hazards they can guard against.

4.1 Disposable Gloves

Disposable gloves used on Baker project sites are usually made of light-weight plastic and are used to help guard against mild irritants.

4.2 Fabric Gloves

Gloves made of cotton or fabric blends are generally used to improve grip when handling slippery objects. They can also help insulate hands from mild heat or cold.

4.3 Leather Gloves

These gloves are used to guard against injuries from sparks or scraping against rough surfaces. They are also used in combination with an insulated liner when working with electricity.

A-3 4.4 Metal Mesh Gloves

These gloves are used to protect hands from accidental cuts and scratches. They are used most commonly by persons working with cutting tools or other sharp instruments.

4.6 Chemical Resistance Gloves

These gloves may be made of rubber, neoprene, polyvinyl alcohol, vinyl, or a variety of other material. The gloves protect hands from chemical exposure such as, corrosives, oils, and solvents. When selecting chemical resistant gloves, the manufacturers' recommendations should be consulted.

5.0 DERMAL PROTECTION

The following is a brief description of a few types of protective clothing and the types of hazards they can guard against This list is not inclusive, there are numerous types and styles of possible protective coveralls designed to offer various degrees of protection.

5.1 Tyvex Coveralls

Tyvex coveralls are inexpensive, disposable spun-bonded, nonwoven polyethylene fiber jumpsuits produced by DuPont. Tyvex provides reasonable tear, puncture, and abrasion resistance protection and excellent protection against particulate contaminants. However, it offers little protection against hazardous liquid or vapor contaminants.

5.2 Saranex Coveralls

While more expensive than Tyvex, Saranex coveralls provide a greater level of protection against both physical and chemical contaminants

53 Polyethylene coated Twex Coveralls

When used as a coating on polyolefm material such as Tyvex, polyethylene increases resistance to acids, bases, and salts.

HEAT STRESS PREVENTION PROGRAM

1.0 INTRODUCTION

Heat stress is a result of the total heat load exceeding the bodies capacities to maintain normal body functions without excessive strain. In the environmental industry the threat is often accompanied by protective clothing decreasing natural body ventilation. If the body's physiological processes fail to maintain a normal body temperature because of excessive heat, a number of physiological reactions can occur, ranging from mild (such as fatigue, irritability, anxiety, and decreased concentration, dexterity, or movement) to fatal.

2.0 SCOPE

This Heat Stress Prevention Program is designed to protect field site employees through regular monitoring and preventive measures. This program present the minimum limits of implementation requirements and also provides an informative reference to recognize, avoid, and treat various forms of heat stress. This is accomplished through the following provisions:

• Causes and Symptoms Prevention Avoidance Monitoring Caring for Heat-Related Illness

3.0 RESPONSIBILITIES

This section will outline the responsibilities of Baker site employees, Project Managers, and Site Managers/Field Team Leaders in regards to implementing this program.

3.1 Project Manager/Site Manager/Field Team Leader

Project Managers/Site Managers or Field Team Leaders are responsible for the implementation of this Heat Stress Prevention Program for all projects involving site personnel. The individuals will direct site personnel to follow the appropriate procedure provided in the Health and Safety Plan or as determined as necessary based on site and environmental conditions.

3.2 Site Health and Safety Officer (SHSO)

The SHSO is responsible for evaluating work tasks and environmental conditions at a field site during the entire duration of the field program. The SHSO will provide the necessary precautions to implement specific site requirements, determine appropriate measures, discuss with the Site Manager and Field Team Leader or contact the Project Manager for assistance.

3.3 Site Employee

It is the employee's responsibility to take proper preventative precautions to avoid a heat stress situation (such as, adequate fluid intake and appropriate rest cycles, monitoring fellow employees and/or following the avoidance monitoring requirements initiated at a specific site. The employee is also responsible to be aware of heat stress conditions and actions as outlined in the 40-hour Occupational Safety and Health hazardous waste worker training. Revision No.: 0 Date: July 1996 Page 3 of6

4.0 PROCEDURES

A prevention and monitoring action will be implemented for Baker employees when the temperature at a site is above 70°F (21 °C). The method used will be determined by the Project Manager with assistance from a Baker health and safety professional and will be included in the site HASP. This method can be evaluated based on monitoring results and adjusted as pertinent.

The following procedures can be used as a guide of heat stress prevention methods. The particular prevention action at a site should be evaluated based on site and environmental conditions in conjunction with work tasks involved.

4.1 Signs. Symptoms, and Conditions

The following heat stress causes and symptoms are provided for buddy monitoring purposes. Site personnel must realize that monitoring the physical condition of fellow personnel in Levels EH- through B protective ensembles will be more difficult

1. Heat rash results from continuous exposure to heat or humid air and chafing clothes. The condition decreases the ability to tolerate heat Symptoms include a mild red rash.

2. Heat cramps are caused by heavy sweating and inadequate fluid intake. Symptoms include muscle spasms and pain in the hands, feet, and abdomen.

3. Heat exhaustion occurs when body organs attempt to keep the body cool, due to inadequate fluid intake and personnel not acclimated to the environment Symptoms include pale, cool, moist skin; heavy sweating; dizziness, headaches, disorientation, abnormal behavior, and vomiting.

4. Heat stroke is the most serious form of heat stress. It is a MEDICAL EMERGENCY. Symptoms are red, hot, dry skin; lack of perspiration; nausea; dizziness and confusion; strong, rapid pulse rate; and coma.

The need to seek medical attention and the urgency in seeking medical attention depends on the symptoms and the severity of the symptoms displayed by the affected individual. If heatstroke is noted or suspected, medical attention must be sought IMMEDIATELY. Efforts should be taken to cool the body to prevent serious injury or death.

4.2 Caring For Heat-Related Illness

To care for heat-related illness provide the following:

• Remove victim from heat.

Loosen tight clothing.

• Apply cool, wet cloths to the skin. Revision No.: 0 Date: July 1996 Page 4 of6

Fan the victim.

If victim is conscious, give cool water to drink.

• Call for an ambulance or transport to hospital if heat stroke is suspected, victim refuses water, vomits, or starts to lose consciousness.

4.3 Prevention

Because heat stress is a common and potentially serious illnesses at environmental sites, regular monitoring and other preventive measures are vital. Site workers must learn to recognize and treat the various forms of heat stress. The best approach is preventive heat stress management. In general:

Monitor for signs of heat stress.

Fluid intake should be increased during rest schedules to prevent dehydration. Drinking cool water (maintained at 50 to 60 °F) is satisfactory when light sweating occurs and temperatures are moderate to cool; however, diluted electrolyte solutions (i.e., Gatorade, Sqwincher, or equivalent) must be used in addition to water under one or all of the following conditions: continued or heavy sweating, moderate to high ambient temperatures, or heavy work loads. The intake of coffee during working hours is discouraged.

Acclimate workers to site work conditions by slowly increasing workloads (i.e., do not begin site work activities with extremely demanding activities).

Use cooling devices to aid natural body ventilation. These devices, however, add weight and their use should be balanced against worker efficiency. An example of a cooling aid is a cooling vest that can be worn under protective clothing, but not against the skin.

In extremely hot weather, conduct field activities in the early morning and evening.

• Ensure that adequate shelter is available to protect personnel against heat that can decrease physical efficiency and increase the threat of heat stress. If possible, set up the command post in a shaded area, and encourage breaks in shaded areas.

• In hot weather, rotate shifts of workers wearing impervious clothing.

Good hygienic standards must be maintained by frequent changes of clothing and showering. Clothing should be permitted to dry during rest periods. Persons who notice skin problems should immediately consult the SHSO.

Develop a suitable work/rest schedule.

4.4 Avoidance Monitoring

Provisions for monitoring for heat stress will be determined by the SHSO and performed as outlined below. Because the incidence of heat stress depends on a variety of factors, all workers, even those not wearing protective equipment, should be monitored. Rcvkion No.: 0 Date: July 1996 Page 5 of6

4.4.1 Permeable Clothing Monitoring

For workers wearing permeable clothing (e.g., standard cotton or synthetic work clothes), the following is a guideline to prevent heat stress situations:

1. Increased awareness of heat stress symptoms and use buddy system to monitor for signs, symptoms, and conditions outlined in Section 4.1.

2. Fluid intake discipline.

3. Self monitoring of fluid input vs output.

4. Attention to work-rest intervals.

Special Considerations

Acclimatization - After approximately one to two weeks, workers should be acclimated to their environment.

Fitness - Physically fit workers will adjust more readily to a change in environment.

• Medication - Some medications can predispose individuals to heat-induced illnesses.

4.4.2 Semipermeable/Impermeable Clothing Monitoring

Baker employees wearing semipermeable or impermeable clothing encapsulating ensembles will be monitored when the temperature in the work area is above 70°F (21 °C). The method used will be determined by the Project Manager with assistance from a Baker Health and Safety Professional. This method can be evaluated based on monitoring results and adjusted as appropriate.

Conduct initial monitoring for heat stress at the start of a project. If conditions remain similar and levels are below the criteria described below in heart rate and oral temperature presented below then use one or more of the items described in Section 4.3.1:

Heart rate. Count the radial pulse during a 30-second period as early as possible in the rest period.

•• If the heart rate exceeds 110 beats per minute at the beginning of the rest period, shorten the next work cycle by one-third and keep the rest period the same.

•• If the heart rate still exceeds 110 beats per minute at the next rest period, shorten the following work cycls by one-third.

Oral temperature. Use a clinical thermometer (3 minutes under the tongue) or similar device to measure the oral temperature at the end of the work period (before drinking).

* If oral temperature exceeds 99.6°F (37.6°C), shorten the next work cycle by one-third without changing the rest period. Revision No.: 0 Date: July 1996 Page 6 of 6

»• If oral temperatures still exceeds 99.6°F (37.6°C) at die beginning of the next rest period, shorten the following work cycle by one-third.

»• Do not permit a worker to wear a semipermeable or impermeable garment when his/her oral temperature exceeds 100.6°F (38.1 °C).

Body water loss. Measure weight on a scale at the beginning and end of each work day to see if enough fluids are being taken to prevent dehydration. Weights should be taken while the employee wears similar clothing or preferably in underwear only. "The body water loss should not exceed 1.5 percent total body weight loss in a work day.

Initially, the frequency of physiological monitoring depends on the air temperature adjusted for solar radiation and the level of physical work. The length of work cycle will be governed by the frequency of the required physiological monitoring.

COLD STRESS

1.0 INTRODUCTION

The potential exists for either frostbite or hypothermia to occur when conducting work activities in an environment where air temperatures may fall below freezing or where wind-chill factors lower air temperatures below freezing. A brief description of the exposure symptoms (for both hypothermia and frostbite) and methods of prevention are listed in the sections below:

2.0 SCOPE

This Cold Stress Prevention Program is designed to protect field site employees through regular monitoring and preventive measures. This program present the minimum limits of implementation requirements and also provides an informative reference to recognize, avoid, and treat various forms of cold stress. This is accomplished through the following provisions:

Causes and Symptoms Prevention Avoidance Monitoring Caring for Cold- Related Illness

3.0 RESPONSIBILITIES

This program includes the responsibilities of Baker site employees, Project Managers, and Site Managers/Field Team Leaders in regards to implementing this program. The responsibilities of these individuals are presented in the Responsibilities section of this manual.

4.0 CAUSES AND SYMPTOMS

The following cold stress causes and symptoms are provided for buddy monitoring purposes. Site personnel must realize that monitoring the physical condition of fellow personnel in Levels D+ through B protective ensembles will be more difficult.

4.1 Frostbite

Frostbite is a condition in which there is a freezing or partial freezing of some part of the body. Individuals previously exposed to frostbite are more susceptible to contracting it Revision No.: 0 Date: April 1997 Page 3 of4 again. Vasoconstrictors, which include tobacco products and caffeine, constrict blood vessels, and can accelerate frostbite. The three stages of frostbite include: (1) frostnip- the beginnings of frostbite whereby the skin begins to turn white; (2) superficial - similar to frostnip except the skin begins to turn numb; and (3) deep - the affected area is frozen to the bone, cold, numb, and very hard.

4.2 Hypothermia

Hypothermia is a condition in which the body loses heat faster than it is produced. At a body temperature of 95 °F, an average man is considered to be hypothermia. Vasodilators, which include alcohol and drugs, allow the body to lose heat faster which can accelerate hypothermia. The five stages of hypothermia include:

(1) shivering (2) apathy, listlessness, or sleepiness (3) unconsciousness, glassy stare, slow pulse or slow respiratory rate (4) freezing of the extremities (5) death

5.0 PROCEDURES

5.1 Prevention

To prevent conditions from occurring have personnel:

Dress in a minimum of three layers:

(1) a skin layer to absorb moisture and keep skin dry (2) an insulating layer (3) an outer layer of nylon/wind-breaking material or chemical-protective layer

Avoid touching cold surfaces (especially metal) with bare skin, minimize exposed skin surfaces.

Keep active, use warm and dry shelter areas during rest cycles; use wind breaks whenever possible.

• Maintain body fluids by consuming warm, sweet, caffeine-free, non-alcoholic drinks. Revision No.: 0 Date: April 1997 Page 4 of4

• Avoid alcohol and medications that interfere with normal body regulation or reduce tolerance to cold.

5.2 Caring for Cold-Related Illness

The need to seek medical attention and the urgency in seeking medical attention depends on the symptoms and the severity of the symptoms displayed by the affected individual. If the latent conditions of hypothermia or frostbite are noted or suspected, medical attention must be sought IMMEDIATELY to prevent permanent injury or death.

The following lists the general guidelines to care for cold-related injuries:

Start by treating any life-threatening problems. Call the local emergency number for help or transport the victim to the nearest hospital. Move the victim to a warm place, if possible. Remove any wet clothing and dry the victim. Warm the victim slowly by wrapping in blankets or putting on dry clothing. DO NOT:

Rub the frostbitten part. Use ice, snow, or anything cold on the frostbitten area. Use heat lamps or hot water bottles to rewarm the frostbitten area. Place the frostbitten area near a hot stove.

53 Monitoring

In cold weather, monitor the outdoor temperature and wind speed to determine wind chill conditions, with work periods adjusted accordingly. The following table details the wind chill effects and relative danger of combined cold and wind conditions. It is important to note that the wearing of PPE in cold environments may introduce the possibility of heat stress; therefore, symptoms of heat stress should also be considered during monitoring.

BLOODBORNE PATHOGENS PROGRAM

1.0 INTRODUCTION

The purpose of the Occupational Safety and Health Adniinistration (OSHA) Bloodbome Pathogens Standard, Title 29 CFR Part 1910.1030, is to protect workers from bloodbome pathogens such as the human immunodeficiency virus (HIV) and hepatitis B virus (HB V) by reducing or eliminating workers' exposure to blood and other potentially infectious materials. Although HIV and HBV are specifically mentioned by OSHA, the standard includes any bloodbome pathogen, such as Hepatitis C, malaria, and syphilis. The standard requires the employer to develop a written exposure control plan that will reduce or eliminate employee exposure, thus reducing their risk of infection.

1.1 Purpose

The purpose of the Baker Environmental (Baker) exposure control plan is to minimize the possibility of transmission of bloodbome pathogens in the workplace and protect employees. This is accomplished by:

1.) Reducing potential exposure

2.) Establishing procedures for the safe handling of first-aid, injury, and/or illness incidents that may expose personnel to blood or other potentially infectious materials

3.) Establishing a means of providing post-exposure evaluation if an exposure incident occurs

1.2 Definitions

Bloodbome Pathogens - Pathogenic microorganisms that may be present in human blood, having the potential to cause disease in humans. Two examples of bloodbome pathogens include, (HIV) and (HBV).

Contaminated - Means the presence or the reasonably anticipated presence of blood or other potentially infectious materials on an item or surface.

Decontamination - Physically or chemically removing, inactivating, or destroying bloodbome pathogens on a surface or item to the point where they are no longer capable of transmitting infectious particles, so that the surface or item is rendered safe for handling, use, or disposal.

Exposure Incident - A specific eye, mouth, other mucous membrane, non-intact skin, or parenteral contact with blood or other potentially infectious materials that result from the performance of an employee's duties.

Occupational Exposure - Reasonably anticipated skin, eye, mouth, mucous membrane, or parenteral contact with blood or other potentially infectious materials that may result from the performance of Revision No.: 0 Date: April 1997 Page 4 of8

an employee's duties.

Other Potentially Infectious Materials - Includes the following human body fluids: semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, peritoneal fluid, amniotic fluid, saliva in dental procedures, any body fluid that is visibly contaminated with blood, and all body fluids in situations where it is difficult or impossible to differentiate between body fluids; any unfixed tissue or organ (other than intact skin) from a human; and HIV-containing cell or tissue cultures, organ cultures, and HTV- or HB V-containing culture medium or other solutions; and blood, organs, or other tissues from experimental animals infected with HIV or HB V.

Parenteral - Piercing of the mucous membranes or the skin barrier through such events as human bites, cuts, and abrasions.

Regulated Waste - OSHA defines a regulated waste as a liquid or semi-liquid blood or other potentially infectious materials; contaminated items that would release blood or other potentially infectious materials in a liquid state if compressed; items caked with dried blood or other potentially infectious materials that are capable of release of these materials during handling; contaminated sharps; and pathological and microbiological wastes containing blood or other potentially infectious materials.

2.0 SCOPE

Baker personnel who may be exposed to blood or other potentially infectious materials as part of their job duties (e.g., those certified in Standard First Aid) are required to follow the guidelines set forth in this procedure. The exposure control plan will be reviewed and updated at least annually, to reflect new or modified tasks and procedures that affect occupational exposure, and to reflect new or revised employee positions with occupational exposure.

3.0 RESPONSIBILITY

This program includes the responsibilities of the Baker Health and Safety Coordinator, Project Manager, Site Manager, Site Health and Safety Officer, and employees. The responsibilities of these individuals are presented in the Responsibilities section of this manual. In addition to the standard responsibilities for these individuals, there are requirements specific to this program and are outlined below.

3.1 Health and Safety Coordinator

The HSC is also responsible for performing the activities outlined in the Baker Incident Reporting and Investigation Program.

3.2 Project Manager/Site Manager

The delegated responsibilities of the Project Manager to the Site Manager include:

• Determining if an exposure incident occurs Revision No.: 0 Date: April 1997 Page 5 of 8

Notifying EMR and setting-up a post-evaluation appointment

Completing the Baker Incident Investigation Form

Notifying the Project Manager and the HSM or HSC if an exposure incident occurs

4.0 PROCEDURES FOR EXPOSURE TO BLOODBORNE PATHOGENS

The sections below will discuss the means by which Baker personnel can determine exposure potential, modes of transmission, methods of compliance, medical monitoring, and post exposure procedures.

4.1 Exposure Determination

The exposure determination is based upon the job classifications with occupational exposure potential, and the activities in which these exposures can occur, as follows.

Job Classifications

Site Manager/Site Safety and Health Officer Environmental Scientists Geologists Other Baker Field Personnel

Exposure Activities

• Response to first-aid, injury, and/or illness incidents involving site personnel

• Decontamination of personnel, personal protective equipment, work surfaces, and equipment potentially exposed to blood or other potentially infectious materials

4.2 Modes of Virus Transmission in the Workplace

Modes of virus transmission are similar for the viruses of concern. Primarily, virus transmission occurs as the result of direct blood contact from contact with an open wound, non-intact skin (e.g., chapped, abraded, or dermatitis), or mucous membranes to blood, blood-contaminated body fluids, or concentrated virus. Protective measures for workers will focus on preventing exposure to blood and other body fluids that can result from an injury or sudden illness.

4.3 Methods of Compliance

4.3.1 Universal Precautions

The unpredictable and emergent nature of exposures likely to be encountered on a site may make identification between hazardous body fluids and those that are not hazardous difficult. Thus, all Revision No.: 0 Date: April 1997 Page 6 of8 employees will observe "Universal Precautions" to prevent contact with blood or other potentially infectious materials. These "Universal Precautions" stress that all blood or other potentially infectious materials will be treated as if they are infectious. The universal precautions will include:

(1) Cover the skin, especially open cuts, scrapes, skin rashes, or other broken skin.

(2) Don't touch objects that could be contaminated, such as blood-covered surfaces, clothing or linens.

(3) Cover mucous membranes (i.e., mouth, nose, and eyes).

(4) Clean and decontaminate surfaces, containers, and equipment that may have been exposed to blood or other body fluids.

4.3.2 Standard Work Practices

Standard work practices are to be implemented at all times by all employees who may be exposed to blood or other potentially infectious materials. Work practices are defined as specific policies or procedures whose purpose is to reduce the potential for employee exposure to bloodbome pathogens. Work practices for use by site personnel are described in the balance of this section.

Personal Hygiene

All exposed employees will observe the following hygienic practices:

During or immediately after exposure to blood or other potentially infectious materials: do not eat, drink, chew gum, chew tobacco, smoke, apply cosmetics, balms or medications, or any other activity that increases the potential for hand-to-mouth, mucous membrane, or skin contact.

• Following exposure to blood or other potentially infectious materials, personnel will wash their hands and any other exposed skin with a disinfectant soap and water after removal of chemical-protective gloves or other personal protective equipment (PPE). This will be performed before eating, urinating, defecating, applying makeup, smoking or undertaking any activity that may result in increased potential for hand to mouth, mucous membrane, or skin contact.

Personal Protective Equipment

Appropriate PPE protects site personnel from exposure to blood and other potentially infectious materials. Appropriate PPE will be made available to all site personnel.

The PPE will be present in the site trailer and field vehicles. The PPE should be used in accordance with the level of exposure encountered. Minor lacerations or small amounts of blood do not merit the same extent of PPE use as required for massive arterial bleeding. Management of the patient who is not bleeding, and has no bloody body fluids, should not routinely require the use of PPE. Revision No.: 0 Date: April 1997 Page 7 of8

The following PPE will be present in each Baker Field Vehicle and/or the Baker Site Trailer:

1. Disposable chemical-protective gloves (such as, nitrile or latex) 2. Resuscitation equipment* 3. Safety glasses or goggles

* Resuscitation Equipment - Because the risk of salivary transmission of infectious disease during artificial ventilation of trauma victims, pocket mouth-to-mouth resuscitation masks will be present in the first aid kits. The pocket mouth-to-mouth resuscitation masks are designed to isolate response personnel from contact with the victims' blood and blood-contaminated saliva, respiratory secretions, and vomitus.

Decontamination procedures will follow those outlined in each site HASP.

Training and Education

All employees with the potential for occupational exposure will receive initial training on the safe handling of first-aid, injury, or illness incidents during first-aid/CPR Instruction, and subsequently during HASP briefings.

4.4 Medical Monitoring

All Baker personnel will follow the medical monitoring guidelines established by Baker's Board Certified Occupational Health Physician in association with EMR, Inc. Also, refer to Baker's Medical Surveillance Program, located within the Baker Health and Safety Programs and Procedures Manual.

4.5 Post-Exposure Procedures and Follow-Up Management

The following subsections present the procedures to follow when a first-aid, injury, or illness incident occurs involving the presence of blood or other potentially infectious material; specific steps need to be taken to safeguard the health of Baker site personnel.

Incident Report

If there is a reasonable cause to believe that a potential exposure to blood or other potentially infectious material has been experienced, the employee must complete the steps listed below. These steps are required when non-HBV vaccinated first aid responders participate and regardless of whether an actual "exposure incident" occurred.

1. Immediately notify the Site Manager and/or SHSO. The Site Manager and/or SHSO will determine whether an "exposure incident" occurred.

2. Wash area of contamination and remove contaminated clothing to ensure that no further contamination will occur.

3. Assist with the completion of the Baker Incident Report Form. Revision No.: 0 Date: April 1997 Page 8 of8

Baker employees who render first aid where blood or other potentially infectious materials are present must be seen by a designated EMR physician within 24 hours (or as-soon-as-possible) of the incident. The employee must take a copy of the Supervisors Incident Report Form and a copy of OSHA Standard 1910.1030 to the physician. EMR can be notified as follows:

EMR phone number 1-800-229-3674 Baker's EMR Client Service Representative - Marilyn McDonald Brooks ext. 440 or follow recorded message procedure if after hours.

Employees who respond to first aid incidents involving the presence of blood or other potentially infectious materials where the determination was made that an "exposure incident" occurred, have, according to OSHA regulation, at least 90 days following baseline blood level collection to decide if they wish to have their blood tested for HIV.

The confidential medical evaluation and follow-up will include:

1. The circumstances of the exposure.

2. If consent has been obtained, testing of the source individual's blood to determine HIV and/or HBV infectivity. If consent is not obtained, it will be documented in writing.

3. If consent has been obtained, the exposed employee's blood will be tested.

4. Availability of the hepatitis B vaccine and vaccination series.

The occupational health physician will provide the employer with a confidential written opinion that includes verification that the employee has been informed of the results of the evaluation and recommendation for further evaluation or treatment A copy of this written opinion will be provided within 15 days following the medical evaluation.
