SECTION C – PROBLEM DEFINITION

Site Background

The Site property is approximately 17.8 acres and consists of fifteen buildings numbered: 7, 14, 8, 15, 33, 28S, 28N, 28N Extension, 29, 27, 42, 26, 25, and 43. The Site was formerly owned by Uniroyal, Inc. (previously The United States Rubber Company) beginning in 1940. Uniroyal manufactured automobile tires at the Site until the plant was permanently closed in 1980. The Site was purchased by Facemate in 1981. Facemate filed for bankruptcy in 2003 and the property was transferred to the City of Chicopee in 2009.

The buildings on the site are presently abandoned and in a state of disrepair. Several of the buildings have been deemed structurally deficient. The City of Chicopee, Office of Community Development, is planning to raze the existing Uniroyal Site buildings as part of its planned property re-development activities. Prior to demolition, the identification of hazardous building materials is necessary and required by a variety of state, federal, and local regulations. Inspection for hazardous building materials will include the identification of potential asbestos containing building materials (ACBM), lead based paint (LBP), PCBs, and mercury containing components. This will allow for the abatement of hazardous materials and segregation of hazardous and recyclable materials prior to building demolition.

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 1 Page 8

Historic Investigations

Smith and Wessel, 2011

Smith and Wessel Associates (SWA) completed an inspection in 2011 for buildings 28, 28N, 28N extension, and 33. The report identified the following regulated building materials:

friable and non-friable ACM lead based paint (LBP) coated metal, wood, brick, and concrete surfaces; PCB containing ballasts; and Fluorescent light bulbs.

CDW, 2012

In May 2012, a Site Specific QAPP was submitted to the Massachusetts Department of Environmental Protection (MassDEP) by CDW Consultants, Inc., of Framingham, Massachusetts under SARSS V Task Assignment Document No. 101577. The purpose of CDW’s 2012 QAPP was to, “identify hazardous materials within the subject buildings that may require abatement and/or special handling and disposal prior to demolition and support beneficial use determinations (BUD) for the waste from demolition.”

The hazardous materials survey completed by CDW included the sampling of suspect asbestos materials, suspect LBP, suspect PCB materials, and an inventory of various quantities of oil and/or hazardous materials (OHM) present in the site buildings. A summary of activities and findings, as presented in CDW’s October 2012 Hazardous Material Summary report, is below.

Buildings 7, 8, 14, 15, 27, 29, 28 Ext, 42, 43 and 45-pump house were included as part of the CDW survey. The survey of buildings 28N, 28S, 28N ext, and 33 were limited to PCBs only and due to unsafe conditions and structural concerns, only an exterior survey of buildings 7, 8, 14, and 15 was conducted.

From June 15, 2012 to July 3, 2012, CDW conducted a visual inspection of the accessible areas of the site buildings in accordance with USEPA, Title 40 CFR part 1, “NESHAP”. During this assessment, 252 samples were collected and submitted to Phoenix Environmental for asbestos analysis via EPA Method 600/R-93/116.

CDW completed a LBP assessment and submitted 52 samples for analysis of total lead by EPA Method 3050B. Forty four of the samples exceeded 0.5% weight total lead and had sufficient sample volume to be submitted for Toxicity Characteristic Leaching Procedure (TCLP) by TCLP 1311. Thirty of the samples submitted for TCLP exceeded 5 mg/L which represents material that requires disposal as a hazardous waste.

As part of the hazardous materials summary, CDW collected and submitted 166 samples of caulking/expansion joint compounds, glazing, and paint for analysis of PCBs. Several of the sample concentrations exceeded the EPA TSCA 40 CFR 761 limits of 50 ppm, and therefore these compounds are classified as PCB bulk product waste.

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 0 Page 9

During the hazardous materials summary, CDW identified other materials that will require special handling. These include light ballasts, electrical transformers, fluorescent bulbs, refrigerants, cathode ray tubes, mercury thermostats, batteries, paints, oils, propane tanks, cleaners, and other miscellaneous liquids.

A summary of the interior and exterior samples collected by CDW in 2012 is included as Table 1.

Proposed Hazardous Material Survey

These various OHMs will need to be segregated and abated prior to demolition, however; a supplemental hazardous building material survey is needed in order to fill in data gaps from the initial survey completed by CDW in June 2012. The results from this survey, along with the data previously collected by CDW, will allow for the preparation of appropriate remediation plans/specifications for qualified contractors to follow during the hazardous material abatement activities as well as determining the appropriate engineering controls and work practices for the abatement and demolition contractors. Actual abatement and associated environmental sampling and monitoring activities related to the abatement and demolition of the hazardous building materials are not incorporated into this QAPP.

Following this survey, SWA and BETA will provide recommendations and related costs estimates to remove and properly dispose of the materials as part of the demolition project. Pre-demolition hazardous material abatement specifications will be prepared. The specifications would include, but are not limited to, the results of the hazardous building material survey, a summary of additional assessment activities (if conducted), and monitoring/clearance requirements during the abatement activities. A licensed and qualified abatement contractor would need to be retained to properly abate the identified hazardous materials, prior to the building demolition activities. It is anticipated, depending upon the results of the planned ACM survey, that an asbestos abatement monitor would be present during ACM abatement activities, to conduct visual inspections, air monitoring, ACM clearance activities, and to observe and document the abatement of hazardous materials.

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 0 Page 10

SECTION D – PROJECT DESCRIPTION/PROJECT TIMELINE

Hazardous Building Materials Survey

This QAPP is designed to be inclusive of the entire Uniroyal Site. However, the hazardous building material survey will only include buildings 7, 14, 33, and 43 at this time. A formal revision to this QAPP will be prepared prior to sampling additional buildings.

The information collected in this investigation will be utilized to:

Prepare an application to the MassDEP for a beneficial use determination (BUD) to allow for the re-use of coated ABC material on-site; and Develop abatement plans and contract documents for the demolition of these four buildings.

Building descriptions are presented below:

Buildings 7 and 14 building characteristics: o Approximate size: 20,970 square feet with 6 floors and a basement o Number of windows: 279 o Number of garage entrances: 9

Building 33 building characteristics: o Approximate size: 25,125 square feet with five floors and a basement o Number of windows: 112 o Number of garage entrances: 2 o Five floors and a basement

Building 43 building characteristics: o Approximate size: 5,550 square feet o Two floors o Number of windows: 10 o Number of garage entrances: 4

Additional Data Requirements

The hazardous building material inspection will include “suspect” ACBM, LBP, PCBs, and mercury containing components. Additional hazardous material data requirements for Building 7, 14, 33, and 43 generally includes:

o Interior sampling of Buildings 7 and 14. This was not completed by CDW during the initial survey due to unsafe building conditions. Interior samples will be collected in areas that are able to be safely accessed. o Synthetic Precipitation Leaching Procedure (SPLP) sampling for the substrates underlying the coatings. The SPLP sampling for lead by CDW focused on the coating alone. Although the analysis of these coatings is important for identifying proper abatement and disposal methods, it does not adequately characterize the materials that have re-use potential on-Site for the purposes of the BUD. o Additional interior and exterior caulking and glazing samples for PCB analysis

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 0 Page 11

o Interior ACBM sampling o Additional PCB analysis of paint chips o Analysis of residual dust for PCBs o Analysis of substrates adjacent to PCB caulking and coatings for analysis of PCBs, and Lead o Inventory of other hazardous materials in the building o Assessment of miscellaneous difficult to manage waste such as comingled debris piles that may require disposal as ACM waste versus non-porous materials that can be inventoried and cleaned for reuse or disposal as general construction debris.

Smith and Wessel will complete the hazardous building materials survey. The survey will be conducted within 2 weeks of the Notice to Proceed and the report will be issued within 4 weeks of the Notice to Proceed.

Special Training/Certification Requirements

Field personnel will have 40-hour OSHA hazardous waste operations (Hazwoper) training. A Massachusetts licensed asbestos inspector will conduct the ACBM inspection and sampling. The lead based paint inspection will be conducted by personnel certified in Massachusetts for LBP inspections. Personnel conducting the bulk coating and PCB caulking sampling will be experienced on the appropriate collection and documentation protocols.

SECTION E – SAMPLING DESIGN AND SITE FIGURES

Inspection Scope of Work and Methodology

Asbestos Inspection

An inspection for suspect ACBM was conducted by CDW in June 2012. A supplemental inspection for suspect ACBM in the interior of Buildings 7, 14, and 33 as well as the exterior of Building 33, will be conducted by SWA’s accredited Asbestos Inspectors. Prior to initiating the on-site inspection process, SWA will review existing drawings and building specifications, and prior investigation results made available to us for original construction information pertaining to the installation of suspect ACBM. In this way, SWA may be able to identify the type and location of some of the suspect ACBM in the buildings, thereby reducing sampling and analysis and saving both time and associated sampling costs. Any reference material used to assist in the investigation of the facility will be clearly referenced in the report, but will not be used as a substitute for SWA’s inspection protocols. As practical, using hand tools, SWA will conduct intrusive investigation techniques to inspect for suspect ACBM that may be hidden in wall cavities, above suspended ceilings and like areas.

In general, SWA will make observations for both friable (easily crumbled, crushed, or pulverized by hand) and non-friable suspect ACBM within the building, including the following materials:

thermal system insulation, such as pipe, boiler, tank, and duct insulation; surfacing materials, such as fireproofing, acoustical and decorative plasters, or other coatings applied by spray or trowel; and miscellaneous materials, such as floor and ceiling tiles, mastics, debris piles, and blown-in insulation.

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 0 Page 12

Not all building materials will be considered to be suspect ACBM. Certain materials, such as fiberglass (pink or yellow), brick, concrete, wood, glass, and rubber can visually be identified as non-suspect ACBM. Also, friable materials that are known to have been installed after 1980 will not be considered suspect. If documentation is made available indicating that non-friable materials do not contain asbestos, these materials also will not be considered to be suspect ACBM. SWA will refer to such available documentation in the report. By classifying certain materials as non-suspect, we can minimize sampling and the associated costs of analyzing the materials.

As necessary, SWA shall collect additional bulk samples of those suspect materials that were not adequately addressed in any of the existing documentation.

The asbestos sampling will be conducted in accordance with National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations 29 CFR 1926. Suspect ACM will be grouped into homogenous areas. To determine the asbestos content of suspect materials, SWA will collect representative bulk samples using the following protocol:

For thermal system insulation, a minimum of three samples of each type, except for small patched areas (less than six square feet), in which case at least one sample will be collected; For surfacing materials, a minimum of three samples of each type of material present in quantities less than 1,000 square feet, a minimum of five samples of each type of material present in quantities 1,000 square feet to 5,000 square feet, and seven samples for homogeneous areas greater than 5,000 square feet; and For miscellaneous materials, at least one sample of each type of material present in quantities less than 500 square feet, and a minimum of two samples of each type of material present in quantities equal to or greater than 500 square feet.

For commingled debris, SWA will collect samples of those materials to be deemed suspect and will determine what of the commingled debris is porous and would require disposal as ACM waste due to cross-contamination. All nonporous materials would be inventoried to be cleaned for reuse or disposal as general construction debris.

While adhering to strict safety precautions, SWA will collect samples of those materials that are readily accessible. Where feasible, SWA will be collecting samples from the roof in order to evaluate the types of roofing materials present and their asbestos content. A professional roofer will be utilized to cut and patch the associated locations on the roof.

Bulk samples will be analyzed by a licensed asbestos analytical laboratory. The analytical method used will be Polarized Light Microscopy (PLM) in accordance with the method described in 40 CFR Part 763, Subpart F, Appendix A. This method is sensitive to the presence of asbestos fibers, typically at less than one percent of the sample composition. In instances where multiple samples of a similar homogeneous material are collected, the laboratory will be directed to analyze each sample of the material until each sample is analyzed or a positive result is obtained (i.e. a sample containing greater than 1% asbestos) so as to avoid the additional costs of repetitive analysis while at the same time retaining analytical quality.

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 1 Page 13 materials. One bulk sample for each type of homogeneous material will be analyzed by Transmission Electron Microscopy (TEM) if all of the initial samples indicate less than one percent asbestos by PLM. Lead Paint Inspection

To identify LBP, SWA will conduct an investigation of the equipment and building components in the interior of Buildings 7, 14, and 33 as well as the exterior of Building 33, that will be impacted by the project in order to identify their lead content. Testing for LBP will be conducted using a portable NITON XLp-303a X-Ray fluorescence analyzer (XRFA) which uses a radioactive source to excite the electrons of lead atoms (if present) in paint. As the lead atom electrons return to their normal state, they emit x-rays that are measured by the XRFA. These data are then processed and the results converted to milligrams of lead per square centimeter of sampled surface area.

To verify calibration, before and after each use SWA will check readings on standards for surface lead of 0.01 mg/cm2 and 1.04 mg/cm2 and buried lead at 0.01 mg/cm2 and 3.58 mg/cm2. Based on the results of the testing for LBP utilizing the XRF, SWA will provide appropriate recommendations for handling and management of wastes and possibly for further testing for LBP chip analysis and/or TCLP analysis.

PCB Inspection

Devices Potentially containing PCBs

SWA's investigation for PCBs will be visual only. SWA will identify light ballasts that may contain PCBs by reading the identification marks on top of a representative sample of light ballasts. Typically, ballasts installed after 1978 do not contain PCBs and are marked as such. Based on the findings in the sample group, conservative assumptions will be made as to the number of ballasts containing PCBs by extrapolating results across the site.

SWA will also inspect for other possible sources of PCBs, such as electrical transformers, which may be present, if they will be impacted by the work of the project. Through visual inspection of labels and other relevant data we will attempt to confirm or deny the presence of PCBs within the examined area. No confirmatory sampling is proposed.

Building Materials potentially containing PCBs

SWA's Environmental Technicians will inspect for suspect caulking sealants, glazing, and expansion joint caulk in the interior of Buildings 7, 14, and 43 as well as the exterior of Building 33. SWA will collect representative samples of the aformentioned materials to be submitted to a qualified laboratory via proper chain of custody for analysis. SWA will collect samples of suspect caulking measuring approximately 25 grams to be analyzed by a qualified laboratory utilizing EPA's SW-846 Method 3540C 8082 SOXHLET Extraction. Any materials containing PCBs equal or greater than 50 ppm are regulated under the Toxic Substance Control Act and the PCB regulation found at 40 CFR Part 761.

Substrates abutting caulking, such as concrete and brick, as well as surficial soils beneath windows, could potentially have become contaminated with PCBs, if present in caulking material. Following an evaluation of the PCB analysis in caulk, an additional assessment program to evaluate these substrates may be necessary.

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 0 Page 14

Additionally, SWA will inspect piles of wood blocks that are located in Building 7. These wooden blocks have tested positive for PCBs. Further investigation is required to determine the extent to which these blocks are contaminated, and the best method for decontamination and disposal. Prior investigations have identified that there is a thin coating on some of the wood blocks that can be peeled off as well as an oil compound that has saturated portions of the blocks. This polyurethane-like coating is not present on all of the blocks, and it is unclear if this coating or the oil compound is the source of the PCB contamination. Laboratory analysis is necessary to evaluate the source of this PCB contamination.

Coated Materials

To determine the re-use potential of the coated asphalt, brick, and concrete materials in the buildings, representative composite samples will be collected. Samples will be collected using hand tools through approximately three inches (i.e., approximately one brick width) of the thickness of the wall at two or more locations. The coatings are adhered to the building walls and represent only a small percentage of the total wall volume. During the planned demolition, the brick and concrete will be crushed and blended with the entire wall volume. These composite samples of coated materials are considered to be conservative representations of the final concentration of crushed coated materials. This is balanced by the results from the separate composite sample of uncoated brick from the exterior wall, which was also collected through approximately three inches of the thickness of the wall. These composite samples of both the coated and non-coated portions of the walls will be compared to the previous sampling of the paint chips conducted in June 2012 by CDW. The composite samples of the interior and exterior brick will then be submitted for RCRA 8 metals analysis, PCB analysis, and leachable lead by SPLP.

Mercury Inspection

To determine handling and disposal procedures for components that may contain mercury, SWA will quantify the number of fluorescent bulbs, switches, and thermostats assumed to contain mercury throughout the buildings. The previous inspection completed by CDW investigated buildings: 43, 42, 27, 28N Extension, 40, 29, and 45. SWA will complete this inspection for Buildings 7, 14, and 33. No confirmatory sampling or analysis for mercury is proposed.

Synthetic Precipitation Leaching Procedure (SPLP)

In association with the BUD application to reuse ABC materials on site as fill, representative samples will be collected and analyzed for SPLP by EPA Method 1312. This method is utilized to evaluate leaching potential due to rainfall and weathering.

Exclusions

It should be noted that some areas of Building 7 and 14 will be restricted due to unsafe building conditions. SWA will make certain assumptions regarding the type and quantity of hazardous building conditions within these areas. As such, while SWA endeavors to conduct a thorough, comprehensive inspection, some exclusion is warranted. SWA's inspection will include building areas only; no assessment of soil, debris, subterranean areas, and inaccessible crawl spaces, interior of equipment, or inaccessible tunnels or trenches will be attempted. Further, spaces behind wall partitions and above suspended or fixed ceilings, inaccessible crawl spaces, interior of equipment, within fire doors, under new windows, and inaccessible tunnels or trenches will only be subject to limited inspection. Additional limitations may impact our ability to inspect all locations such as unsafe conditions, poor lighting, height constraints, unusual building

Quality Assurance Project Plan Chicopee August 26, 2013 Rev. 0 Page 15 features, occupancy, and stored materials. SWA will not inspect for hidden materials. Such conditions, if encountered during site inspection, will be documented in the inspection report.

Many roofing systems are not conducive to complete characterization by inspection and core sampling only. For instance, a rubber membrane may cover an entire roof with a variety of built-up systems underneath. Without complete removal of the membrane, the inspector would be unable to determine if there are two or perhaps multiple different sections of different built-up roofs, tars, patches, and so on. Thus, SWA cannot warrant the complete identification and proper characterization of all roof materials. It is appropriate to provide this caution to allow for cost contingencies and appropriate use of demolition methods by contractors.

Often, roofing materials were put down in layers and may include several types (e.g. a repair patch), although this may not be apparent upon visual inspection and limited sampling. SWA will collect samples and make assumptions pertaining to roofing materials based on sampling results and observation, but SWA findings should not be construed to be definitive pertaining to the extent of materials present. Only upon removal of the entire roofing system will the exact nature of roofing materials be known. This building is currently unoccupied and SWA will contract a professional Roof Contractor to assist with the sampling of roof materials.

While SWA will follow industry standards during the inspection, we do not warrant that all suspect hazardous building materials will be identified in or on the building within the inspection areas and we shall not be held liable related to abatement costs related to hazardous materials that are either not discovered or not appropriately characterized. This is due in part to inherent problems with every building inspection, such as, but not limited to:

o Seemingly homogeneous materials that are not in fact homogeneous, o Seemingly representative locations that are not in fact representative, o Layered materials that are not uniformly present or are isolated, o Materials that are present in an isolated and limited quantity, o Materials that were accessible but that were not recognized as being hazardous or potentially hazardous, o Materials in locations that are unsafe or otherwise difficult to access.

During the course of future demolition work, it is possible that additional hazardous materials or materials suspected of being hazardous will be identified. Such materials should be assumed to be hazardous unless appropriate evaluation or sampling and analysis demonstrate otherwise. Contracts, specifications and plans should advise contractors to conduct controlled demolition work and stop immediately should any hazardous building materials be encountered during the course of their work.

A Site Locus is included as Figure 1 and a Site Plan of the building is attached as Figure 2.

SECTION H – FIELD EQUIPMENT CALIBRATION & CORRECTIVE ACTION Equipment used in the field during the monitoring program will be calibrated according to the manufacturer’s instructions. The field monitoring task manager will be responsible for the equipment calibration, maintenance, and repair during the supplemental assessment program. Equipment not used at monitoring sites will be stored and maintained at the office.

A Niton XLp-303a XRF will be utilized to conduct the LBP screening. To verify calibration, before and after each use SWA will check readings on standards for surface lead of 0.01 mg/cm2 and 1.04 mg/cm2 and buried lead at 0.01 mg/cm2 and 3.58 mg/cm2. The field equipment calibration table below lists equipment routinely used that must be calibrated to maintain performance. The XRF Performance Characteristic Sheet is included as Appendix A.

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 15

SECTION I – LABORATORY EQUIPMENT CALIBRATION & CORRECTIVE ACTION Routine maintenance procedures and schedules for sampling equipment and field measurement instruments are described in the manufacturer’s instruction manuals. All records of inspection and maintenance will be dated and documented in the field notebooks by the field monitoring task manager.

Maintenance procedures and schedules for all analytical instruments will be in strict conformance with the recommendations of the equipment manufacturers. Routine maintenance will be performed by laboratory personnel as needed. Specialized inspection and maintenance of major equipment will be performed by trained service personnel from the manufacturers in accordance with instrument service contracts. All records of inspection and maintenance will be dated in the laboratory record books. Reference is made to the SOPs included as Appendix A for further information on laboratory equipment calibration.

SECTION J – SAMPLE H ANDLING AND CUSTODY REQUIREMENTS A chain-of-custody (COC) program will be followed during sample handling activities from the field through laboratory operations. The COC program is designed to assure that each sample is accounted for at all times. In general, the objective of the COC identification and control system is to assure, to the extent practical, that all samples are uniquely identified, the correct samples are analyzed for the correct parameters, and samples are protected from loss or damage. Chain of Custody records will include the consultant name and address, sample ID, sample location, collection date and time, matrix type, signatures of samplers and those in custody of the samples.

A copy of a COC form, and sample label are included in Appendix C. The Field Monitoring Task Manager will be responsible for maintaining field data sheets, COC records, and sample labels for each sample collected, as well as a detailed log of daily field activities.

Samples will be identified using a descriptive system, such as an alpha-numeric system or equivalent. Sample IDs will be recorded on the sample container, and the sample location will be marked on a Site plan for reference.

However, even negligible levels of lead would prompt adherence with OSHA guidelines when impacting and TCLP lead levels may not be in excess of 5 ppm or it triggers segregation for disposal as hazardous lead waste.

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 17

SECTION L – FIELD QUALITY CONTROL

Internal quality control (QC) checks will help monitor the performance of the field sampling and laboratory activities. This section describes the QC checks that will be implemented to ensure that the data generated in the monitoring program is of known quality.

Sampling Quality Control Checks

During bulk ACM and PCB sample collection activities, duplicate samples of homogenous materials will be collected.

During the XRF screening activities, the instrument calibration will be checked at the beginning and end of testing and every four hours during the testing period. If warranted, re-sampling or re-analysis may be required.

SECTION M – LABORATORY QUALITY CONTROL

Analytical Quality Control Checks Along with the field quality control requirements, the Massachusetts DEP-certified laboratory being utilized maintains a quality control/quality assurance program. Table 2 summarizes the laboratory quality control requirements.

Relative Percent Difference (RPD) is a measure of precision and the percent surrogate recovery is a measure of accuracy. The objective of the laboratory concerning precision is to equal or exceed the precision demonstrated in the published analytical method on similar samples. RPD is calculated as follows:

RPD = (Sample Result - Duplicate Result) x100 Mean of Sample and Duplicate Results

The objective of the laboratory concerning accuracy is to equal or exceed the accuracy demonstrated in the published analytical method on similar samples. Accuracy is determined on matrix spikes and/or blank spikes and is calculated as follows:

Percent Recovery = (Observed - Sample) Concentration x 100 Spiked Concentration

Precision is a measure of the reproducibility of the results. This quality control indicator is evaluated by examining the variability of results from field duplicates and laboratory duplicates. The precision objective for this investigation is to meet or exceed the criteria that have been established for the referenced analytical methodology. Corrective action will be implemented by the laboratory as necessary to correct any substantial deviations.

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 18

Accuracy is a measure of the closeness of the analytical result to the true concentration. The percent recovery of spiked samples and performance evaluation standards reflect whether the analytical result has a high or low bias. The accuracy objective for this investigation is to meet or exceed the criteria that have been established for the referenced analytical methodology. Corrective action will be implemented by the laboratory as necessary to correct any substantial deviations.

** In some cases, the surrogate recovery will fall out of the acceptable percent recovery range indicated. In this case the laboratory will usually reanalyze the sample. Interference from non-target analytes, dilutions, or soil characteristics may prevent the laboratory from achieving an acceptable percent recovery. In this case, the

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 19

laboratory will make note of these anomalies and the sample will not be reanalyzed. Other QC data will be used to validate the field samples.

This test evaluated Con-test’s proficiency with regards to establishing the value of a sample within the acceptance limits. The PCB analyses performed by Con-test and evaluated by the New State Department of Health were all found to be Satisfactory.

SECTION N – DATA MANAGEMENT & DOCUMENTATION

Field Documents and Records: Field documentation may include field notes, field screening data, sketches, building material sampling logs, and inspection recording forms. Field notes will include project location, date of field activities, weather conditions, and the purpose of site visit. Field sketches and photographs may be used to document current site conditions. All field notes and site documentation will be scanned and filed electronically in the appropriate project folder. Copies of SWA standardized material sampling logs and inspection recording forms are included as Appendix D.

For sample collection, data reporting will begin in the field and will be tightly interwoven with the chain-of- custody procedures. Upon collection of each sample, the sampling team will record in a field notebook the sample number, sampling location, date, and time of collection. Some of this information will also be recorded, as necessary, on the sample bottle label and on the chain-of-custody record.

Laboratory Documents and Records: In the laboratory, incoming samples will be stored in a designated location, for which a log book will be maintained by the laboratory sample custodian. The log book will record sample storage location, sample

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 20 storage conditions, and the transfer of samples to the analytical areas for analysis. The analyst receiving samples also will maintain a log book, in which the sample number, sample characteristics, and the results of sample analysis and data reduction will be recorded. The results of all sample analysis will be recorded by laboratory personnel onto data sheets. The final data sheets, as well as all bottle labels, sample custodian log books, and field notebooks will be forwarded to the Project Manager upon their completion.

The laboratory data package includes a project narrative for the data, which will identify any problems or deviations with the samples or chain of custody. Following the project narrative, the data results sheets will show preparation and analysis dates, sample concentrations, units, reporting limits, and percent solids for soil/sediment samples. The laboratory data package also contains a laboratory quality control package documenting method blanks, surrogates, and laboratory control samples.

Post Laboratory Data Manipulation: Once the laboratory data is obtained, the sample results will be manually transferred into an Excel database. Quality control checks will be performed by SWA to ensure the data is entered correctly and that the analytical data meets the criteria outlined in Sections K and M of this QAPP. The output of the data validation effort will be a data usability report that will attest to the suitability of the data for its intended use.

The field inspector will review analytical data to determine if suspect materials meet the classification as regulated materials (e.g. do suspect asbestos materials contain greater than one percent). Supplementary analytical data of like materials will be reviewed by the inspector and the QC manager for consistency. For those materials meeting the regulated criteria, the inspector will enter the information into the report, as appropriate, and then reviewed by the QC manager for accuracy. Reports shall be submitted to the client for draft review. Following all comments, the reports will be finalized and issued to the client.

Project Files: All project files including field notes, Site plans, laboratory analytical reports, summaries of analytical data, and other miscellaneous information related to the project will be filed both electronically and in hard copy form in designated project folders. BETA will keep all files related to the project for at least 10 years after the project has been completed.

SECTION O – ASSESSMEN TS AN D RESPONSE ACTIONS

Throughout the course of the project, BETA will implement the following procedures to detect and correct any problems that may occur:

Z Project management meetings; Z Peer reviews of all reports, documents, and correspondence;

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 21

Z Weekly project team meetings; Z Periodic field meetings during all site investigations; and Z Ongoing communication between BETA’s project team, the client, and all Subcontractors.

As warranted, problems that occur will be communicated through the issuance of project memorandums and telephone conversations. All correspondence will detail the problem encountered and any corrective actions taken. All memorandums and telephone notes will be maintained in dedicated project files.

All field sampling will be overseen by the Project Manager to ensure that the QAPP and sampling SOPs are followed. Any sampling problems will be immediately communicated to the Project Manager and documented in the field notes.

Corrective Actions If the quality control detects unacceptable conditions or data, the Project Manager will be responsible for developing and initiating corrective action. The Quality Assurance Officer will determine whether the nonconformance is significant or requires specialized expertise or remedial analyses. Corrective action may include the following:

Reanalyzing samples (if holding times permit) Resampling and reanalyzing Evaluation and amending sampling and analytical procedures Accepting the data and acknowledging the level of uncertainty or inaccuracy by flagging the data and providing a qualifying explanation

SECTION P – PROJECT REPORTS

As the field component of this project is to be conducted within a short timeframe, one report will be issued. On the basis of the information gathered during the inspections, a final project report will be prepared, detailing the findings and appropriate recommendations regarding the hazardous building materials identified. The report will include an inventory of ACBM, LBP, mercury containing devices and PCBs, as well as analytical results, regulatory guidance, and recommendations for abatement and control of those hazards. The report will also include recommendations for additional assessment and/or estimated costs for abatement or other appropriate engineering controls for each hazardous material identified.

The reports will be prepared by the field monitoring task manager, and then reviewed by both the quality assurance and project manager. Copies of all reports will be submitted to the assigned EPA contacts, as well as the client.

The final report will include a complete site history, summary of activities performed at the site including analytical results, any and conclusions/recommendations. Site plans and laboratory analytical reports will typically be included, as well as any other relevant information. The report will be submitted in hard copy

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 22 format, with an electronic copy available if requested. Attachments containing a large number of pages (such as analytical laboratory reports) may be submitted electronically on a CD.

SECTION Q – FIELD DATA EVALUATION The field data evaluation will include a detailed review of all information obtained over the course of the project (field notes, photographs, field screening results, analytical results, etc.). The field data will be analyzed for trends and any discrepancies between the data. The final report will discuss information documented in field notes. Laboratory analytical reports and photograph logs, will be included in the report as attachments. The report will also include tables summarizing results of all samples collected to date. The field data evaluation will be performed by the designated quality control manager.

SECTION R – LABORATORY DATA EVALUATION A final data evaluation will be performed by the designated SWA quality assurance manager to verify the completeness of the laboratory data package and confirm that all requirements set forth in the QAPP have been met. This will include both a review of the field data collection protocols and an evaluation of the laboratory data with respect to the quality control criteria discussed in Sections K and M of this QAPP. Any questions or missing information will be addressed with the laboratory and any important information will be provided in the final report.

As part of the data evaluation procedure, chain of custodies, sample preservation, quantification limits, and holding time results will be reviewed. Any issues identified will be documented, and potential impacts to the sampling data will be recorded.

All field QC samples will then be evaluated. Any observations, trends, and limitations observed in the field and/or laboratory QC data will be interpreted and documented in the final report.

SECTION S – DATA USABILITY AND PROJECT EVALUATION

Data usability will be based on meeting some or all, but not limited to the following criteria:

Z Deviations from any standard operating procedures will be reviewed to identify potential limitations in the data. If a substantial deviation to standard operating procedure is identified, consideration may be given to either re-sampling or disregarding the sample result. Z If concentrations of target analytes are at or near a RC, quality control data (blanks, spikes) will be scrutinized to determine the likelihood of false negatives and false positives. If QC data indicates that precision or accuracy is determined to be outside method specific criteria, then an evaluation of the data will be

Quality Assurance Project Plan Chicopee June 22, 2013 Rev. 0 Page 23

performed to determine where and how this QC issue affects the use of the data. The results of this evaluation will be presented in the final report along with a discussion of any limitations in the way the data should be used. If, after the evaluation, it is determined that the data is unusable, the data will be rejected and possible corrective actions will be documented in the final report. Z A review of sample representativeness from field notes will be performed. A non- representative or non-homogeneous sample increases the potential for false negatives or false positives. Adherence to applicable field sample collection protocols, field QC measures, XRF instrument calibration requirements, and transport and storage of sample to the laboratory will decrease the possibility of having a sample result that is not representative of true site conditions. Z Poor data quality or lost samples will decrease confidence in the data set. To ensure completeness, adherence to all field protocols, sample tracking procedures, and laboratory procedures shall be maintained. Completeness will be described in terms of the total number of samples that meet data validation requirements compared to the total number of samples that do not satisfy such requirements. Z At the completion of the project, an overall assessment of the project data (field and laboratory) will be performed to determine whether the goals and objectives of the project were met and whether there were any observations, trends, anomalies, or data gaps noted. The results of this assessment will be documented in the final report.

Standard Operating Procedures

Inspection Scope of Work and Methodology

Asbestos Inspection The inspection for suspect ACBM will be conducted by SWA’s accredited Asbestos Inspectors. Prior to initiating the on-site inspection process, SWA will review existing drawings and building specifications made available to us for original construction information pertaining to the installation of suspect ACBM. In this way, SWA may be able to identify the type and location of some of the suspect ACBM in the buildings, thereby reducing sampling and analysis and saving both time and associated sampling costs. Any reference material used to assist in the investigation of the facility will be clearly referenced in the report, but will not be used as a substitute for SWA’s inspection protocols. As practical, using hand tools, SWA will conduct intrusive investigation techniques to inspect for suspect ACBM that may be hidden in wall cavities, above suspended ceilings and like areas.

In general, SWA will make observations for both friable (easily crumbled, crushed, or pulverized by hand) and nonfriable suspect ACBM within the building, including the following materials:

Not all building materials will be considered to be suspect ACBM. Certain materials, such as fiberglass (pink or yellow), brick, concrete, wood, glass, and rubber can visually be identified as non-suspect ACBM. Also, friable materials that are known to have been installed after 1980 will not be considered suspect. If documentation is made available indicating that nonfriable materials do not contain asbestos, these materials also will not be considered to be suspect ACBM. SWA will refer to such available documentation in the report. By classifying certain materials as non-suspect, we can minimize sampling and the associated costs of analyzing the materials.

As necessary, SWA shall collect additional bulk samples of those suspect materials that were not adequately addressed in any of the existing documentation.

Asbestos Sampling Protocol

To determine the asbestos content of suspect materials, SWA will collect representative bulk samples using the following protocol:

1,000 square feet to 5,000 square feet, and seven samples for homogeneous areas greater than 5,000 square feet; and For miscellaneous materials, at least one sample of each type of material present in quantities less than 500 square feet, and a minimum of two samples of each type of material present in quantities equal to or greater than 500 square feet.

While adhering to strict safety precautions, SWA will collect samples of those materials that are readily accessible and can be sampled without extensive damage to existing finishes. The samples collected will be as small as reasonably feasible in order to obtain a representative portion of the substrate. If SWA will be collecting samples from the roof in order to evaluate the types of roofing materials present and their asbestos content, a professional roofer will be utilized to cut and patch the associated locations on the roof.

Although PLM is the method accepted by the EPA for detecting the presence of asbestos in bulk samples, it is not consistently reliable in detecting asbestos in floor tiles and in some other types of organically bound materials. Therefore, if less than one percent asbestos is detected in these materials, confirmatory analysis using Transmission Electron Microscopy (TEM) will be recommended. Lead Paint Inspection To identify LBP, SWA will conduct an investigation of the equipment and building components that will be impacted by the project in order to identify their lead content. Testing for LBP will be conducted using a portable NITON XLp-303a X-Ray fluorescence analyzer (XRFA) which uses a radioactive source to excite the electrons of lead atoms (if present) in paint. As the lead atom electrons return to their normal state, they emit x-rays that are measured by the XRFA. These data are then processed and the results converted to milligrams of lead per square centimeter of sampled surface area.

PCB Inspection

Devices Potentially containing PCBs

SWA's investigation for PCBs will be visual only. SWA will identify light ballasts that may contain PCBs by reading the identification marks on top of a representative sample of light ballasts. Typically, ballasts installed after 1978 do not contain PCBs and are marked as such. Based on the findings in the sample Standard Operating Procedures April, 4 2012 Smith & Wessel Associates, Inc. 3 | Page group, conservative assumptions will be made as to the number of ballasts containing PCBs by extrapolating results across the site.

Building Materials potentially containing PCBs

SWA's Environmental Technicians will inspect for suspect caulking and sealants only in locations that may be impacted by the work of the project. SWA will collect representative samples of the aformentioned materials to be submitted to a qualified laboratory via proper chain of custody for analysis. SWA will collect samples of suspect caulking measuring approximately 25 grams to be analyzed by a qualified laboratory utilizing EPA's SW-846 Method 3540C 8082 SOXHLET Extraction. Any materials containing PCBs equal or greater than 50 ppm are regulated under the Toxic Substance Control Act and the PCB regulation found at 40 CFR Part 761.

Mercury Inspection To determine handling and disposal procedures for components that may contain mercury, SWA will quantify the number of fluorescent bulbs, switches, and thermostats assumed to contain mercury throughout the buildings. No confirmatory sampling or analysis for mercury is proposed.

Exclusions While SWA endeavors to conduct a thorough, comprehensive inspection, some exclusion is warranted. SWA's inspection will include building areas only; no assessment of soil, debris, subterranean areas, and inaccessible crawl spaces, interior of equipment, or inaccessible tunnels or trenches will be attempted. Further, spaces behind wall partitions and above suspended or fixed ceilings, inaccessible crawl spaces, interior of equipment, within fire doors, under new windows, and inaccessible tunnels or trenches will only be subject to limited inspection. Additional limitations may impact our ability to inspect all locations such as poor lighting, height constraints, unusual building features, occupancy, and stored materials. SWA will not inspect for hidden materials.

SWA cannot warrant the complete identification and proper characterization of all roof materials. Often, roofing materials were put down in layers and may include several types, although this may not be apparent upon visual inspection and limited sampling. SWA will collect samples and make assumptions pertaining to roofing materials based on sampling results and observation, but our findings should not be construed to be definitive pertaining to the extent of materials present. Only upon removal of the entire roofing system will the exact nature of roofing materials be known. SWA will contract a professional Roof Contractor to assist with the sampling of roof materials and make the appropriate repair of sample locations against future leaks.

1.0 SCOPE AND APPLICATION

Method 8082 is used to determine the concentrations of polychlorinated biphenyls (PCBs) as Aroclors in extracts from solid and aqueous matrices. Open-tubular, capillary columns are employed with electron capture detectors (ECD). When compared to packed columns, these fused-silica, open-tubular columns offer improved resolution, better selectivity, increased sensitivity, and faster analysis. The target compounds may be determined by either a single- or dual-column analysis system. The method also may be applied to other matrices such as oils and wipe samples, if appropriate sample extraction procedures are employed. The following analytes can be determined by this method:

PCB-1016 PCB-1254 PCB-1221 PCB-1260 PCB-1232 PCB-1262 PCB-1242 PCB-1268 PCB-1248

Reporting Limit = 20 ug/L (off of the instrument), <0.1 mg/Kg and <0.2 ug/L (calculated). MA CAM RL’s = 0.25ug/L and 0.1 mg/kg

2.0 SUMMARY OF METHOD

A measured volume or weight of sample (approximately 1-Liter for liquids, 10 grams for solids) is extracted using the appropriate matrix-specific sample extraction technique (e.g. Microwave -3546 or ASE -3545 or Soxhlet -3540C). Aqueous samples are extracted at pH 5-9 with methylene chloride, solid samples are extracted with 1:1 Acetone:Hexane. Extracts for PCB analysis may be subjected to a sulfuric acid clean-up, which will remove many single component organochlorine or organophosphorus pesticides. Therefore, Method 8082 is not applicable to the analysis of such compounds. Instead, use Method 8081. After clean-up, the extract is analyzed by injecting an aliquot into a gas chromatograph with a narrow bore fused silica capillary column and electron capture detector (GC/ECD).

3.0 INTERFERENCES

3.1 Interferences co-extracted from the samples will vary from matrix-to-matrix.

3.1.1 Contaminated solvents, reagents, or sample processing hardware. 3.1.2 Contaminated GC carrier gas, parts, column surfaces, or detector surfaces. 3.1.3 Compounds extracted from the sample matrix to which the detector will respond. 3.1.4 Co-elution of target analytes. 3.1.5 Clean-up procedures include: Florisil column clean-up, Florisil cartridge clean- up, TBA clean-up (for sulfur interferences: used for either PCBs or pesticides), and sulfuric acid clean-up (only performed for PCBs, never for pesticides).

3.2 Interferences by phthalate esters can pose a major problem in PCB determination. Common flexible plastics contain varying amounts of phthalates. These phthalates are easily extracted or leached from such materials during laboratory operations. For this reason, avoid the use of plastics in the laboratory.

3.3 Cross-contamination of clean glassware routinely occurs when plastics are handled during extraction steps, especially when solvent-wetted surfaces are handled. Glassware must be scrupulously cleaned.

NOTE: Oven-drying of glassware used for PCB analysis can increase contamination because PCBs are readily volatilized in the oven and spread to other glassware. Therefore, exercise caution, and do not dry glassware from samples containing high concentrations of PCBs with glassware that may be used for trace analyses.

3.4 Subtracting blank values from sample results is not permitted.

Remove 60 ml vials from ASE once sequence is complete.

Place 60 ml vials in Turbo Vap Concentration System. Bath temperature should be between 40-45 C. Concentrate down to approximately 10 ml.

Pass remaining 10 ml extract portion through a glass funnel lined with filter paper and sodium sulfate into a 25 ml concentrator tube. Rinse sodium sulfate with Hexane and concentrate to 10.0 ml final volume.

8.1.2 Microwave Extraction – Method 3546 (refer to Method 3546 SOP)

8.1.3 Soxhlet Extraction – Method 3540C (refer to Method 3540 SOP)

8.2 EXTRACTION FOR WATER

8.2.1 The pH of all samples is checked with pH paper at the time of log-in. The pH must be between 5-9. If the pH is not in the proper range, adjust accordingly with either 1N NaOH or 1:1 H2SO4. Record the volume of acid or base used.

8.2.2 To measure the volume of sample, draw a line on the sample container at the meniscus of the sample. Transfer the entire sample to a separatory funnel. Rinse the sample container with the first 60 mL aliquot of methylene chloride and transfer to the separatory funnel. At a later time, place water in the sample container so the meniscus is up to the line drawn. Measure this volume in a graduated cylinder to the nearest 5 mLs and record. If one liter of sample is not available, record amount of sample used and bring up to one liter with DI water. CON-TEST ANALYTICAL LABORATORY SOP8082ARev7 39 Spruce Street Doc. No. 51 Rev7 East Longmeadow, MA 01028-0591 Date: 4/13/2011 Page 8 of 17 8.2.3 Add 1.0 mL of 2,4,5,6-Tetrachloro-m-xylene (TCMX) and Decachlorobiphenyl (DCB) at 1000 ug/L surrogate standard to all samples, spikes and blanks.

8.2.4 Add 1 mL of spike standard to all LFBs ("lab spikes") and matrix spikes. True value = 500 ug/L (50 ug/L off of the instrument). 1016/1260 is used per method. Alternate Aroclors may be warranted based on site specific conditions.

8.2.5 Add 60 mLs of methylene chloride to the separatory funnel. Stopper and shake vigorously for 2 minutes with periodic venting to release excess pressure. Allow the organic layer (bottom layer) to separate from the water phase for a minimum of 10 minutes. If an emulsion exists between layers, the analyst must employ mechanical techniques such as swirling, stirring, and centrifugation, to complete phase separation.

8.2.6 Pass the solvent layer through a glass funnel, lined with filter paper containing anhydrous sodium sulfate into a BOD bottle. Repeat extraction two more times using fresh solvent and combine the three solvent extracts. After the third extraction, pass additional methylene chloride through the sodium sulfate (collecting it in the BOD bottle) to rinse it.

8.2.7 Prepare the TurboVap cells by rinsing them twice with methylene chloride.

8.2.8 Transfer the extracted samples from the BOD bottles into the rinsed TurboVap cells. After adding the sample to the cell, rinse the BOD bottle once with methylene chloride and add that rinseate to the sample.

8.2.9 Samples are concentrated using a Zymark TurboVap II concentration unit. The water level within the TurboVap II as well as the temperature should be checked before beginning. (The water temperature should be set to 38°C for the concentration of PCBs)

8.2.10 Before placing the samples in the TurboVap, adjust the nitrogen pressure to approximately 6 psi to avoid splashing of the sample when concentration begins. Add the samples to the TurboVap and begin concentration.

8.2.11 As the samples are being concentrated, adjust the nitrogen pressure in order to maintain a vortex within the cell as the volume decreases. The nitrogen pressure should be slowly increased from the original pressure of 6 psi up to a maximum of 12 psi.

8.2.12 When the sample reaches a volume of 5 mL, remove it from the TurboVap and perform a hexane exchange by adding 50 mL of hexane and aspirating with a disposable Pasteur pipette.

8.2.13 Replace the samples in the TurboVap and concentrate to a volume of approximately 8 mL

8.2.14 After the samples have been concentrated to 8 mL, remove the cells from the TurboVap. Transfer the sample to the 10-mL volumetric using a disposable pipette. Rinse the TurboVap cell with approximately 1-2 mL of hexane and add that rinseate to the 10-mL volumetric. Bring the samples up to a final volume of 10 ml.

8.2.15 Transfer the sample to a 12-mL amber screw top vial. CON-TEST ANALYTICAL LABORATORY SOP8082ARev7 39 Spruce Street Doc. No. 51 Rev7 East Longmeadow, MA 01028-0591 Date: 4/13/2011 Page 9 of 17 8.3 PROCEDURE - EXTRACTION FOR WIPES/TO-4/SOIL

8.3.2 Extract concentration

Remove 60ml vial from ASE carousel and pour extract through glass funnel lined with filter paper containing sodium sulfate into a turbo vap concentration tube.

Place vessel in water bath with a stream of nitrogen for blow down.

Concentrate extract to approximately 8-9 mLs.

Rinse sides of concentration vessel with 1-2ml hexane and bring up to a final volume of 10mls – using a 10-mL volumetric flask, transfer to a 12-mL amber, screw top vial.

Take aliquot of 1000 uLs for GC/ECD analysis.

8.4 SAMPLE EXTRACT CLEAN-UP

8.4.1 An acid clean-up is performed on all PCB samples and their corresponding QC. Never do an acid clean-up on the same sample aliquot that is to be analyzed for pesticides. Pipette approximately 2 mLs of sample extract into a 4-mL screw cap vial that contains about 1 mL of sulfuric acid (transfer the remaining sample into a labeled 4-mL vial and place in the freezer). Cap the vial and shake for approximately 30 seconds. Allow the layer to separate then pipette off about 1- mL of sample and transfer to a labeled crimp top vial.

TBA Clean-up

8.4.2 Sulfur is removed by Method 3660B; Tetrabutylammonium (TBA) sulfite reagent. Prepare reagent by dissolving 3.39g Tetrabutylammonium hydrogen sulfate in 100 mL organic-free reagent water. To remove impurities, extract this solution three times with 20 mL portions of hexane. Discard the hexane extracts, and add 25g sodium sulfite to the water solution. Store the resulting solution, which is saturated with sodium sulfite, in an amber bottle with a PTFE-lined screw cap. This solution can be stored at room temperature for at least one month.

8.4.2.1 Transfer 1.0mL of sample extract to a 10mL clear vial with a PTFE-lined screw cap.

8.4.2.2 Add 1.0mL TBA sulfite reagent and 2mL 2-propanol, cap vial, and shake for 1 min. If the sample is colorless or if the initial color is unchanged, and if clear crystals (precipitated sodium sulfite ) are observed, sufficient sodium sulfite is present.

8.4.2.3 Add 5mL organic free reagent water and shake for a least 1 min. Allow sample to stand for 5-10 min. Transfer the hexane layer (top) to a 1mL auto sampler vial.

10.0 Sample Analysis

Analyze samples by GC along with solvent blanks, calibration standards, method blanks (extracted blanks) and all appropriate quality control samples.

Samples are generally analyzed by an auto sampler. If an auto sampler stalls, lab analysts will restart the analysis using two blanks and an acceptable continuing calibration verification standard.

All Aroclor standards must be run for pattern recognition before running samples. Patterns are established before any sample analysis at the beginning of a sequence.

Aroclors are identified based on retention time and PCB pattern matching. Samples must be analyzed on a confirmation column if the qualitative identification of PCB is suspect. Retention times must fall within established windows on both columns.

11.0 CALCULATIONS

12.1 Definitions

For definitions and explanations of quality control measures, refer to section 4.0 of the Con-Test Analytical Quality Control Manual.

12.2 Quality Control Measures & Acceptance Criteria

12.2.1 Calibration Curve

A 5-point calibration curve is used to calibrate the system. The curve must contain Aroclors 1016 and 1260. The low standard must be 0.99). The curve must be verified with an independent standard (ICV) prior to sample analysis, (50ug/L). All other Aroclors will also be quantitated from a five point calibration curve.

If a peak is not properly integrated by the data system, manual integration may be necessary. Manual integrations must comply with the Con-Test SOP on Chromatographic Integration Procedures. The integration of the peaks for the samples and quality control samples must be as consistent as possible with the integration used with the initial calibration. All manual integrations must be documented. In particular, the chromatogram must be expanded to clearly show the specific peak being integrated. A “before” integration is printed, showing the software integration, or lack thereof. An “after” integration showing the action taken by the analyst is printed. The analyst initials and dates both records and they are included with the rest of the documentation for that data file.

The method file used by the data system for the initial calibration should be named with a unique identifier for initial calibration. The initial calibration method file includes a “C” as a suffix to denote that it is the original file. When the retention times change for target compounds due to daily instrument maintenance, the original file is copied to (saved as) a new file with the “C” suffix removed. The method file without the “C” suffix indicates that the retention times have been changed from the initial calibration. The original initial calibration method file with the “C” as a suffix must not be changed.

If the initial calibration does not meet the acceptability criteria, it may not be used for quantitative analyses. Investigate the cause of the problem and perform instrument maintenance if necessary. Then repeat the initial calibration.

12.2.2 Retention Time Windows

Retention time windows will be determined by calculating the mean and standard deviation of the absolute retention times of the surrogate compounds and three (minimum) to five major peaks for each Aroclor. CON-TEST ANALYTICAL LABORATORY SOP8082ARev7 39 Spruce Street Doc. No. 51 Rev7 East Longmeadow, MA 01028-0591 Date: 4/13/2011 Page 14 of 17 For the Aroclors, each selected peak will be characteristic of that Aroclor, will be at least 25% of the height of the largest Aroclor peak, and will include at least one peak that is unique to that Aroclor. The retention times used for these calculations should be taken from three injections of the Aroclor standards made over a 72-hour period.

If the standard deviation of the retention times for any peak is 0.000, a default standard deviation of 0.01 minutes may be used. The width of the retention time window for each surrogate and Aroclor peak will be ±3 times the standard deviation of the mean absolute retention time established during the 72-hour period.

12.2.3 Continuing Calibration Check (Calibration Check Standard)

Performed every 12 hours and after no more than 20 samples, and at the end of the analytical sequence. Must be at the mid-point of the curve and contain at least Aroclors 1016 and 1260. For samples run by MA MCP / CT RCP / 8000B protocols , % RSD must be within 15% of the initial calibration. For samples run by 8000C protocols % RSD must be < 20%. An Aroclor hit in a sample must have calibration verified with a one-point standard of that Aroclor within 12 hours.

The calibration check standard must meet the acceptance criteria before any samples are run. If the calibration check does not meet the acceptance criteria, corrective action is required including instrument maintenance. If the calibration check still fails the acceptance criteria, a new initial calibration is required.

12.2.4 Method Blank

Analyzed on each working day to demonstrate that no contamination is present. The method blank is matrix specific, and extracted with every batch of 20 samples or less. The target compounds and ranges must be

12.2.5 Laboratory Control Samples (LCS) / Quality Control Check Samples

Matrix-specific LCS’s are extracted and analyzed with every batch of 20 samples or less. The concentration should be between the low and mid-level standard, and must contain at least Aroclors 1016 and 1260. Percent recoveries must fall within control limits. Percent recoveries must be 40- 140 %R to meet MCP Data Enhancement and RCP criteria. RPD between LCS and LCSD is <20% for waters and <30% for soils.

Water prep: 1 mL of appropriate 500 ppb spike to a final volume of 10 mL. True value = 50 ug/L off of the instrument.

Soil/Solid prep: Add 1-mL of Spike 2000ppb to 10 grams of sample, to a final volume of 10 mL. True value = 200 ug/Kg.

12.2.6 Matrix Spikes/Matrix Spike Duplicates

A matrix-specific MS/MSD is extracted and analyzed with every batch of 20 samples or less. It must contain at least Aroclors 1016 and 1260. Percent recoveries must fall within control limits established from historical data. Percent recoveries must be 40-140 %R and MSRPD must be <50%

12.2.7 Surrogates

Surrogates are added to all blanks, standards, samples, and spikes. Analyze a minimum of two, one that elutes at the beginning of the run and one that elutes at the end of the run (TCMX and DCB). Percent recoveries must fall within control limits established from historical data. Percent recoveries must be 30-150%R in order to meet MCP Data Enhancement and RCP criteria. If the %R is outside of control limits on both columns for the same surrogate, re-extract the sample. If both surrogates are outside limits on one column only, reanalyze the sample. If a surrogate is diluted to a concentration below that of the lowest calibration standard, no corrective action, aside from narration, is necessary.

12.2.8 Confirmation

Confirm any hits on a second dissimilar column; report the higher of the two results, unless obvious interference is present on one of the columns. RPD between primary and confirmatory column should be <40%. All QA/QC parameters (e.g. calibrations, LCSs, etc) must be met on the 2° column as well. For samples analyzed under 8000C protocols the lower of the two results is reported unless obvious interference is present from one of the columns.

13.0 DATA PROCESSING

13.1 GC files

A file naming convention is used that allows differentiation between updates to the calibration file performed to adjust target retention times for the changes brought about by daily chromatographic maintenance (no file suffix) and updates due to analysis of a new calibration curve (addition of a “C” suffix to the file identifier)

13.1.1 PCBs

15.0 POLLUTION PREVENTION

Pollution prevention encompasses any technique that reduces or eliminates the quantity and or eliminates the quantity and or toxicity of waste at the point of generation. Many opportunities for pollution prevention exist in laboratory operation. Whenever feasible, laboratory personal should use pollution prevention techniques to address waste generation. When it is not feasible to reduce wastes at the source, recycling is recommended as the next best option. Standards should be prepared in volumes consistent with laboratory use to minimize the volume of expired standards to be disposed.

16.0 WASTE MANAGEMENT

It is the laboratory’s responsibility to comply with all federal, state, and local regulations governing the waste management, particularly the hazardous waste identification rules and land disposal restrictions, and to protect the air, water, and land by minimizing and controlling all releases from fume hoods and bench operations. Also, compliance is required with any sewage discharge permits and regulations.

Any PCB containing samples with over 2.0 ppm are labeled and stored separately for disposal. Used standards are accumulated as a lab-pack and sent out to be disposed properly by a waste management company. CON-TEST ANALYTICAL LABORATORY SOP8082ARev7 39 Spruce Street Doc.

5.0 PROCEDURE FOR EXTRACTION OF SOIL

5.1 Weigh out 10g of solid sample into disposable pour-boat weighing dish.

5.2 Blend in anhydrous sodium sulfate (make sure sample is free-flowing)

5.3 Place sample in an extraction thimble. The extraction thimble must drain freely for the duration of the extraction period. A glass wool plug below the sample in the Soxhlet extractor is an acceptable alternative for the thimble.

5.4 Add 400mL of 1:1 mixture of Hexane/Acetone to a 500mL round bottom flask. Add several boiling chips. Place a Soxhlet Extractor on top of the round bottom flask; make sure to slightly twist – to ensure a tight connection.

5.4 Label the round bottom flask with the sample number. Place the corresponding thimble into the Soxhlet extractor.

5.5 Add desired amounts of surrogate standard to all samples, spikes and blanks.

5.6 Add desired amounts of spike to all LFB's (lab spikes) and matrix spikes.

5.7 Place the round bottom flask with attached Soxhlet extractor onto a heating mantel and attach condenser unit. Turn on water to cool the condensers.

5.8 Turn corresponding thermostats on to setting 5. At this time double check Soxhlet for any cracks or chips which may leak solvent. Once the solvent begins to boil, a flushing action of once every two to three minutes should be achieved.

5.9 The samples should be extracted overnight for a minimum of 16 hours. Once the sample has finished extracting, turn the heating mantle off and allow samples to cool to room temperature. Once cool, disengage condenser unit and flush the remaining solvent from the Soxhlet extractor by tipping the Soxhlet. Disengage the Soxhlet extractor from the flask and put aside. Using a pair of long-handled tweezers, pull the thimble out of the Soxhlet place in hood for total solvent evaporation. Repeat for all other samples.

5.10 Prepare a glass funnel lined with filter paper and filter with sodium sulfate by rinsing with hexane. Pass the extract through the funnel into a clean Turbo-Vap tube. Rinse the 500mL Flask with 10-15mLs of fresh solvent and pass it through the funnel. Rinse the funnel with hexane.

5.11 Zymark Turbo-Vap Concentrator Workstation Settings Endpoint Selection: Sensor Bath Temperature: 45 C Nitrogen Gas Pressure: Pressure should be high enough as to keep a constant vortex ripple on the surface of the extract without splashing.

5.12 Open Zymark Turbo-Vap cover and place Turbo-Vap tube with extract in appropriate cell ( example: Cells 1 – 6 ). Start sample concentration by turning on the appropriate cell, a light CON-TEST ANALYTICAL LABORATORY SOP3540Crev0 FD 39 Spruce Street Doc. No. 127Soxhlet East Longmeadow, MA 01028-0591 Date: 3/30/09 Page 6 of 7 will turn on indicating cell is on. Note: As a precaution the Turbo-Vap system regulators should be checked to assure that no residual gas pressure remains within the system and that

gas pressure regulators is off before placing samples in the apparatus. Residual gas pressure may cause splashing and cross contamination of samples.

5.13 Concentrate the sample to approximately 5.0mL. Remove the samples from the Turbo-Vap and place in the rack. Note: Not all samples will evaporated at the same rate. Samples which stop reducing, should be removed as soon as possible.

5.14 Quantitatively transfer the sample extract with a Pasteur pipette into an appropriate volumetric. Rinse the Turbo-Vap with hexane and transfer to volumetric. Repeat two more times. Bring up to a final volume of 10mL with Hexane. Transfer contents into two pre- labeled 4mL screw top vials.

6.1.6 Surrogates

Surrogates are added to all blanks, standards, samples, and spikes.

7.0 POLLUTION PREVENTION

Pollution prevention encompasses any technique that reduces or eliminates the quantity or toxicity of waste at the point of generation. Many opportunities for pollution prevention exist in laboratory operation. EPA has established a preferred hierarchy of environmental management techniques that places pollution prevention as the management option of first choice. Whenever feasible, laboratory personnel should use pollution prevention techniques to address waste generation. When it is not feasible to reduce wastes at the source, the Agency recommends recycling as the next best option.

Dear Mr. Erickson: Your laboratory's scores for the Environmental Laboratory Approval Program (ELAP) Non-Potable Water/Solid &Chemical Materials/Air & Emissions Chemistry Proficiency Test are enclosed.

ELAP validates the fitness for use of each sample/analyte used in it's PT studies. After the study close date samples/analytes are evaluated again for stability in conjunction with historic pass/fail rates. The evaluation procedures used to establish the assigned value are discussed in the ELAP Certification Manual Item 300. Metrological traceability and measurement uncertainty for value assignment is established using a Type B approach as described in the U.S. Guide to the Expression of Uncertainty in Measurement (ANSI/NCSL Z540-2-1997). All analytes were determined to be fit for use as PT materials for this study.

The assigned value is the 'made to' value for the analyte. The mean for scoring is either the predicted mean from the FoPT Tables or the participant consensus mean. The acceptance limits are centered on the mean for scoring and calculated as plus/minus three times the standard deviation or the fixed percentage, as denoted using the % symbol, stated in the report. In some cases, the acceptance limits are manually adjusted to conform with the FoPT table footnotes 4 through 6. In these cases, the standard deviation cannot be used to set the acceptance limits.

From the sample reporting instructions, step 3, provided in the sample shipment package(s); participants are reminded to use the appropriate FoPT PTRLs for "Less Than" reporting of non detects and detections below the PTRL.

The statistical procedures used to establish study means, standard deviations and acceptance limits are described in the ELAP Certification Manual Item 330.

The PT Program does not limit the usage of proficiency test reports by individuals or organizations. The PT Program only distributes PT reports to the participant and any organization selected by the participant for distribution.

Summary statistics by method, as well as, assigned value uncertainties may be requested by contacting the PT Program. Also, please provide us with your feedback on any issues related to the PT Program, including the current study. Direct any comments, requests, feedback, or questions to us at [email protected].

Method Description This method is used to determine asbestos content in a variety of relatively homogenous building materials. Subsequent to various preppingg techniques, the sample is analyzed by both a stereomicroscope and Polarizedd LighLight Microscope (PLM). Asbestos is identified by measuring a number of opticalptical propeproproperties including refractive indices. Asbestos percent is determinedned by calibcalibrated visual estimate (CVE) or point counting.

Test Method Summary Including Scope and Application Bulk samples are examined under stereoscope to locate suspect fibers for identification. After the initial identification samples are homogenized and prepared for quantitation by CVE or point counting. This procedure should be used to determine the asbestos content of bulk building materials and includes procedures for various prep techniques and quantitation methods. Due to the procedure's use of multiple preps and re-preps, as well as numerous preparation options, bulk building materials are specified due to their inherent gross

Sample Collection, Preservation, Shipment and Storage Samples are collected in a manner which produces no fiber release and are commonly collected using strong ‘zip lock’ or ‘whirl pak’ bags. Only one sample should be placed in each bag. No preservation is required. Bulk samples are not to be shipped or stored with air samples. Samples are retained in an easily retrievable manner for a minimum of 60 days.

Limit of Detection Under normal conditions, the practical detection limit for thiss method is one (1) percent. Detection limits can vary with sample type, amountount of sampsamsample analyzed or method of quantitation used. For example, the 1,000000 point countcounco method can report values down to 0.1%.

Method Description This method is for the determination of asbestos concentrations in air samples by Transmission Electron Microscopy (TEM). Air samples are collected on a membrane filter, prepped via a direct prep method and analyzeded withwitw an electron microscope at 20,000 X magnification capable of Energy Dispersivespersive X-RayX Analysis (EDXA).

Test Methodd SummarySummar Including Scope and Application This method iss for theth determination of asbestos concentrations in air samples by Transmission ElectronectUncontrolledUn Microscopy (TEM). Although originally developed as a means for final clearance after asbestos abatement, it is also used for baseline studies or ambient air testing. Samples are prepared in the lab via a direct prep method. Analysis is performed at approximately 20,000 X magnification. Asbestos structures are identified by a combination of morphology, elemental chemistry via Energy Dispersive X-Ray Analysis (EDXA), and Selected Area Electron Diffraction (SAED). 70 structures/mm2 is the Pass/Fail criteria but strictly speaking this limit is applicable only when air samples are collected (aggressively) post remediation and in groups of at least 13 samples (5 in the work area, 5 outside of the work area, 2 field blanks, and a sealed blank). Alternately, compliance may be determined by comparing the inside and outside sample results using a statistical comparison called a Z-Test.

Controlled Document Confidential Business Information/Property of EMSL Analytical, Inc. Page 1 of 3 Overview of TEM AHERA Method Revision 0 November 16, 2010

Sample Collection, Preservation, Shipment and Storage Samples should be collected on 0.45μm pore size MCE filters. For 25 mm cassettes, the minimum samples volume in 560L and if the inside screen test is to be used 1200L. Collection flow rates should not exceed 10 L/min. No sample preservation is needed and samples can be stored indefinitely prior to analysis. Samples are best transported to the lab by hand. When mailing, try to package samples carefully to minimize disturbance and possible dislocation of particulate from the filter surface. Use packing materials that will minimize static charge, it is recommended to avoid the use of "foam peanut" packing material. All air cassettes are retained in an easily retrievable manner for a minimum of 60 days. Samples should not be stored or shipped with bulk samples.

Limit of Detection For any given analysis the method detection limit is 1 confirmedonfirmed asasbestos structure.

Calibration and Standardization Each major component of the methodthodd is calibcalibrated and/or standardized including; camera constant and TEM magnification,gnification,nification, sspot size and beam dose, EDXA system performance includingng peak loclocalocations, resolution and sensitivity factors.

Sample Preparation A ¼ wedge of the samplempleple filtfilterer is cut and removed from the filter. This filter section is placed on a microscmicromicroscope slide and cleared with acetone vapors, 5% of the filter’s surfacece is removremoved with a low temperature plasma asher and the filters are coated with a thin layllayer of evaporated carbon. The samples are then dissolved afterer being placedp on a copper grid in a Jaffe Wick. Once complete the grid preps are storedtoreUncontrolled in numbered grid boxes for analysis and archival.

Sample Analysis – Interpretation and Calculations Sample grids are inserted into the TEM and grid openings are chosen. Asbestos structures are located, and then identified and measured at a magnification of 15000 - 20000X. Structures (fibers, bundles, clusters and matrices) containing asbestos fibrils meeting the method counting criteria (0.5μm in length and 5:1 aspect ratio) that can be identified as asbestos are counted. Counting continues until enough grid openings are analyzed to reach an analytical sensitivity of 0.005 s/cc. Alternately analysis may be terminate after 50 structures are counted in a minimum of 4 grid openings or if over 50 structures are identified in any 1 grid opening. The grid openings should be selected evenly over 2 grid preps.

If an analysis of the waste itself demonstrates that the total concentrationsentration of the TCLP analytes are well below 20 times the regulatory limits, then the TCLP needd not be run. 1.2 Summary of Method 1.2.1 A representative sample of the waste undergoes a preliminary analysis to determine its particle size, alkalinity, and percent solids contents. If no liquid phase is present, the sample is subdivided, if necessary, and extracted with 20 times its weight of extraction fluid, acetic acid or an acetate buffer, for 18 ± 2 hours in a glass vessel rotated at 30 rpm. The filtrate is preserved where necessary and analyzed for TCLP metals. If the test sample contains greater

The filtrate is separated; the solid phase is subdivided if necessary, then is extracted with 20 times its weight of one phase forms when they are mixed) and analyzed for TCLP metals. If incompatible, they are analyzed separately and the results are combined mathematically to give a volume-weighted average concentration. If the test sample contains less than 0.5% solids, it is filtered and analyzed for TCLP metals. 1.2.2 Holding times are as follows: Samples for TCLP mercury analysis must be extracted within 28 days of the collection date and analyzed within 28 days of the extraction date. Samples for other TCLP metalss mmust be extracted within 180 days of the collection date and analyzed withinthin 180180 daysday of extraction date. 1.2.3 No preservative is added to the raw sample.mple. SamplesSample may be refrigerated at 4°C; if irreversible sample change, ssuchuch aass formationforma of a precipitate, occurs as a result, then the entire sample, includingncluding tthehe pprecipitate, shall undergo extraction. 1.2.4 Extracts for the determinationtion ooff TTCLPCLP mmetals shall be preserved with concentrated nitric acidd toto a pHpH lessless thant 2. If a precipitate forms that remains after acidification, thethe extractextract fforor metals must be stored at 4°C without preservation. 1.3 Reporting Limit 1.3.1 The currentcurrent reportingreportin limit for this method is 0.4 mg/L, equal to the lowest calibrationalibration standardstand used. 1.3.2 TheThe currentcurrent EPA regulatory limit for TCLP lead is 5.0 mg/L. 2.0 Interferences andd C Contaminationono tam Management 2.1 Chemical interferencesUnncontrolledf are caused by lack of absorption of atoms bound in molecular combination in the flame. This phenomenon can occur when the flame is not sufficiently hot to dissociate the molecules. One way to prevent this is to add some salts (i.e., lanthanum chloride). Chemical interferences may also be eliminated by separating the metal from the interfering material using complexing agents. 2.2 The presence of high dissolved solids in the sample may result in interference from non- atomic absorbance such as light scattering. If background correction is not available, a non- absorbing wavelength should be checked. Preferably, samples containing high solids should be extracted.

Controlled Document Confidential Business Information/ Property of EMSL Analytical, Inc. EMSL.TCLPSOP.101.0 Revision 2 / 12.03.07 Page 3 of 20 2.3 Ionization interferences occur when the flame temperature is sufficiently high to generate the removal of an electron from a neutral atom, giving a positively charged ion. This type of interference can generally be controlled by the addition, to both standard and sample solutions, of a large excess (1,000 mg/L) of an easily ionized element such as K, Na, Li or Cs. 2.4 Spectral interference can occur when an absorbing wavelength of an element present in the sample but not being determined falls within the width of the absorption line of the element of interest. The results of the determination will be erroneously high, due to the contribution of the interfering element to the atomic signal. This interference can be reduced by narrowing the slit width. 2.5 Samples and standards should be monitored for viscosity differencesiffer that may alter the aspiration rate.

2.6 All metals are not equally stable in solution, especiallyally ifif itit ccontainsontain only nitric acid and not hydrochloric acid. Digestates should be analyzedzed asas soonsoon asas possible after preparation.

Install the lid, close the pressure relief valve, and hook up nitrogen. Position the tared receiving vessel beneath the assembly. 7.1.7 Allow the sample to filter by gravity. When the filtration has ceased for 2 minutes, pressurize the vessel gradually to 10 psi with nitrogen gas. Proceed until liquid flow through the filtration apparatus has ceased for 2 minutes and the flow of nitrogen gas is observed, then increase the pressure in increments of 10 psi to a final pressure of 50 psi. When liquid flow ceases for 2 minutes, stop the filtration, disconnect the nitrogen source, and depressurize the vessel. 7.1.8 The filtrate is defined as the liquid phase of the sample.amp The portion of the sample left in the filtration assembly is defined as the solidsolid phase.phase Determine the weight of the liquid phase by subtracting the containerner weightweight fromfrom the total weight of the filtrate and container.

Comments regarding QC failures must be addressed before issuance of client reports. 8.0 Calculations and Reporting

8.1 Initial filtrate versus TCLP leachate 8.1.1 Two liquids are generated when a multiphasic waste is analyzed: the initial filtrate and the leachate. If the filtrate is miscible with the leachate, the two solutions are mixed prior to analysis. If the two solutions are not miscible, they are analyzed separely, and the results are combined mathematically.

The mathematical calculations are performed viaa thethe followingfo equation if the TCLP filtrate and extract are not miscible.

V1 = the volume of the first pphasehase (liquid)(lil quid) (L)(L

9.1 MDLs may be established using matrix material fortified at a concentration of two to three times the estimated method detection limit. To determine MDL values, take seven replicate aliquots of matrix material fortified with a liquid spike and process through the entire analytical method. Perform all calculations and report concentration values in the appropriate units. Calculate the MDL as follows: MDL = t · S Where,

t = Student’s t value for a 99% confidence level and a standardd deviation estimate with n-1 degrees of freedom. (t = 3.14 for seven replicates). S = standard deviation of the replicate analyses 9.1.1 The concentration utilized for the MDL sstudytudy mmustust beb less than 10 times the calculated MDL. 9.1.2 The calculated MDL must be atat leastleast 2 timestimes below the reporting limit (RL). 10.0 Quality Control.

Dilutions of sample solutions should be made using acid concentrations similar to the original preparation. 10.5 Corrective actions and contingencies for multiphasic wastes 10.5.1 Subsampling stratified waste is difficult. Therefore, the analyst should consider calculating percent solids from the same sample container used for the TCLP extraction instead of compositing all the sample containers. this is the largest error in the TCLP leaching process. The laboratory must consider the amount of each phase present in each bottle and adjust the calculations accordingly. Therefore, estimate and record the number of phases, appearance, and volume of each sample phase before starting analysis.

EMSL.TCLPSOP.101.0 Revision 2 / 12.03.07 Page 14 of 20 10.5.2 The particle size of multiphasic material may be difficult to assess. The lab should identify procedures to classify multiphasic samples which are not amenable to size measurement. 10.5.3 Five grams of sample are usually used to determine the appropriate TCLP leaching fluid. If there is not enough volume of any individual phase, less material may be used. However, the ration reagent water and acid to sample must be maintained if smaller samples are used. 10.5.4 The pH of the filtrate should be recorded. This provides useful information when validating field or laboratory duplicates. 10.5.5 The filtrate volume should also be measured. Thishis informationinf will be needed if the multiple phases must be mathematically combined.mbined.

If more than three quality control requirements are not met, the entire QC batch can not be reported, and the client notified. If the quality control failure can be demonstrated to have no significant effect upon the integrity of the analytical results, no report disclaimer is required.

Overview of EMSL Analytical SOP Asbestos by TEM NIOSH 7402 Issue 2 - August 15, 1994

Method Description This procedure is for the determination of optically visible asbestos fibers in air by Transmission Electron Microscopy (TEM). Air samples are collected on mixed cellulose ester membrane (MCE) filters and TEM grids are preparedeparedepare using a portion of the filter and examined using TEM. During TEM ExaminationExaminatioamina all fibers are identified, counted and enumerated.

Applicable Matrices This method is used to determine the identity off fibersfifib rs on an air sample collected during asbestos related activities. Typically thee samplesamsamp ecopy filter filt has previously been analyzed using Phase Contrast Microscopypy (PCM). HHowever, since PCM does not differentiate between asbestos and otherother fibersfibefibers, the proportion of asbestos fibers to total fibers, as determinate by TEM, are applied to the previously calculated PCM Air concentration in f/ccf/cc to determineded the overall Asbestos Fibers/cc.

Interferences Interferences for this methodethodod includeincludincl but are not limited to: - High levels off non-fibrous on-fibrou dust particles may obscure fibers in the sample and indirectlyctly increaseincreas the detection limit of a sample. - Non-regulatedulated amphamphiboles or scrolled clay particles, such as richterite or sepiolite,ite, may havehavh aspect ratios > 3:1 and possess SAED or EDXA spectraa similarsimila to asbestos minerals. - Non-asbestiformestifestiUncontrolled varieties of the amphibole asbestos minerals may form cleavage fragments that are indistinguishable from asbestos by this method.

Test Method Summary Including Scope and Application This method should be used for air samples collected on 0.45 to 1.2 μm mixed cellulose ester membrane (MCE) filters using 25 cassettes with a conductive cowl, at air flow rates of 0.5 to 16 L/min. Sample volume should be adjusted to give 100 to 1300 fibers/mm2 where possible. Samples are prepared with a direct preparation technique without plasma ashing. Samples are observed using a TEM and optically visible fibers counted (fibers with widths 0.25μm). Raw counts are then converted into a proportion of asbestos fibers to total fibers and applied to the previously determined air fiber concentration (f/cc)

from PCM analysis. This method is used to measure airborne asbestos fiber concentration.

Sample Collection, Preservation, Shipment and Storage No sample preservation is needed and samples can be stored indefinitely prior to analysis. Samples are best transported to the lab by hand. When mailing, try to package samples carefully to minimize disturbance and possible dislocation of particulate from the filter surface. Use packing materials that will minimize static charge, it is recommended to avoid the use of "foam peanut" packing material. All air cassettes are retained in an easily retrievable manner for a minimum of 60 days.

Limit of Detection The limit of detection for this method is 1 confirmed asbestosbestosestos fiber.fibfiber The detection limit of the combined NIOSH 7400/7402 resultesultsult is <0.0<0<0.01 f/cc for atmospheres free of interfering dust, and will bee higherhih herer forfo moremo heavily loaded samples copy . Calibration and Standardization Each major component of the methodod iss calibratcalibrated and/or standardized including; camera constant and TEM magnification,fication,tion, spospot size and beam dose, EDXA system performance including peak locatiolocations, resolution and sensitivity factors.

Sample Preparation A ¼ wedge of the sampleple filtfilterer is cuccut and removed from the filter. This filter section is placed on a microscomicroscopmicroscope slide and cleared with acetone vapors, coated with a thin layer off evaporatedvaporat carbon and then the filter dissolved after being placed on a copperpper grid in a Jaffe Wick. Once complete the grid preps are stored in numbered grid boxesboxe for analysis and archival.

Sample AnalysisisUncontrolled – Interpretation and Calculations Sample grids are inserted into the TEM and grid openings are chosen. At a low magnification (500 - 1000), fibers are located, and then identified and measured at a higher magnification (10000 - 20000). Fibers meeting the method counting criteria (>5 μm in length and 3:1 aspect ratio and a minimum width of 0.25μm) lying within a grid opening are counted. Fibers entirely within the grid opening are counted as 1 fiber, fibers interesting a grid bar once are counted as ½ fiber and fibers lying outside the graticle field or intersecting the grid bar twice or more are not counted. Counting continues until 40 grid openings selected evenly over 3 grid preps are counted or 100 fibers are counted in a minimum of 6 grid openings. The proportion of asbestos to total fibers is calculated and applied to the associated PCM result for the sample being analyzed. Combined PCM 7400/ TEM 7402 sample results are reported in Asbestos fibers / cc.

Quality Control Each laboratory must adhere to the quality control and quality assurance procedures described in EMSL’s Quality Assurance Manual. Instrument and analyst calibration is performed prior to analysis as listed above. Sample analysis is subjected to 10% recount QC. These randomly selected samples are resubmitted to the original analysis for recounting and the recounts are tested with the statistically evaluation in the method.

BACKGROUND INFORMATION

EVALUATION DATA SOURCE AND DATE:

This sheet is supplemental information to be used in conjunction with Chapter 7 of the HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing ("HUD Guidelines"). Performance parameters shown on this sheet are calculated from the EPA/HUD evaluation using archived building components. Testing was conducted in August 2004 on 133 testing combinations. The instruments that were used to perform the testing had new sources; one instrument’s was installed in November 2003 with 40 mCi initial strength, and the other’s was installed June 2004 with 40 mCi initial strength.

OPERATING PARAMETERS: Performance parameters shown in this sheet are applicable only when properly operating the instrument using the manufacturer's instructions and procedures described in Chapter 7 of the HUD Guidelines.

SUBSTRATE CORRECTION VALUE COMPUTATION: Substrate correction is not needed for brick, concrete, drywall, metal, plaster or wood when using Lead-in- Paint K+L variable reading time mode, the normal operating mode for these instruments. If substrate correction is desired, refer to Chapter 7 of the HUD Guidelines for guidance on correcting XRF results for substrate bias.

EVALUATING THE QUALITY OF XRF TESTING: Randomly select ten testing combinations for retesting from each house or from two randomly selected units in multifamily housing. Use the K+L variable time mode readings. Conduct XRF retesting at the ten testing combinations selected for retesting. Determine if the XRF testing in the units or house passed or failed the test by applying the steps below. Compute the Retest Tolerance Limit by the following steps: Determine XRF results for the original and retest XRF readings. Do not correct the original or retest results for substrate bias. In single-family housing a result is defined as the average of three readings. In multifamily housing, a result is a single reading. Therefore, there will be ten original and ten retest XRF results for each house or for the two selected units. Calculate the average of the original XRF result and retest XRF result for each testing combination. Square the average for each testing combination. Add the ten squared averages together. Call this quantity C. Multiply the number C by 0.0072. Call this quantity D. Add the number 0.032 to D. Call this quantity E. Take the square root of E. Call this quantity F. Multiply F by 1.645. The result is the Retest Tolerance Limit. Compute the average of all ten original XRF results. Compute the average of all ten re-test XRF results. Find the absolute difference of the two averages.

2 of 3 Niton XLp 300, 9/24/2004, ed. 1

If the difference is less than the Retest Tolerance Limit, the inspection has passed the retest. If the difference of the overall averages equals or exceeds the Retest Tolerance Limit, this procedure should be repeated with ten new testing combinations. If the difference of the overall averages is equal to or greater than the Retest Tolerance Limit a second time, then the inspection should be considered deficient. Use of this procedure is estimated to produce a spurious result approximately 1% of the time. That is, results of this procedure will call for further examination when no examination is warranted in approximately 1 out of 100 dwelling units tested.

TESTING TIMES: For the Lead-in-Paint K+L variable reading time mode, the instrument continues to read until it is moved away from the testing surface, terminated by the user, or the instrument software indicates the reading is complete. The following table provides testing time information for this testing mode. The times have been adjusted for source decay, normalized to the initial source strengths as noted above. Source strength and type of substrate will affect actual testing times. At the time of testing, the instruments had source strengths of 26.6 and 36.6 mCi.
