1. Introduction

On behalf of Master Lock Company, LLC (Master Lock) and Fortune Brands Home & Security (FBHS), Haley & Aldrich, Inc., (Haley & Aldrich) has prepared this Final Report for Completed Non-Emergency Immediate Action (Final Report) of the Elevator 8 - total petroleum hydrocarbon (TPH)-diesel range organics (DRO) release area (Site). This Final Report is prepared in accordance with requirements provided in Wisconsin Administrative Code (WAC) Chapter NR 700 (General Requirements), specifically, WAC Chapter NR 708.09 (No Further Response Action).

1.1 PURPOSE AND SCOPE

Haley & Aldrich has prepared this Final Report to demonstrate the Site meets the requirements of a non-emergency immediate action as defined in WAC NR 708.05(3), and to request a No Further Response Action for Case #02-41-563540 under the provisions outlined in WAC NR 708.09.

1.2 SITE LOCATION AND RESPONSIBLE PARTIES

Site location, as shown on Figure 1:

Master Lock Company, LLC (Responsible Party) 2600 North 32nd Street Milwaukee Township (1307N21E – Township/Range/Section), Milwaukee County, Parcel No. 3269998113 Milwaukee, Wisconsin DNR BRRTS Activity #02-41-563540 DNR FID #241038820

The Site is centered on Elevator 8, a four-story freight elevator shaft of concrete block construction. The elevator shaft is located on the southern side of Building 14 (press room). At the exterior of the elevator shaft, to the west and south, is a parking lot. Building 15, containing a boiler room and electrical substation, is present to the east of the Site, and Buildings 12 and 13, tool room and press room, respectively, are present to the west of the elevator shaft. The combination lock area (Building 16) and the heat treat area (Building 17) are located to the south of the Site on the opposite side of the parking area. The Site Plan is shown on Figure 2.

Responsible parties for the Site include Master Lock and FBHS.

1.3 ELEVATOR 8 BACKGROUND

In 2011, Master Lock initiated proactive replacement of its 1970s-era elevator jacks using double bottom jacks with secondary PVC jackets to reduce the potential of hydraulic oil releases to the subsurface. Prior to repair, the elevator jack-hole had a 24-inch diameter steel casing extending 32 feet below the shaft floor (a total of 43 feet below ground surface [bgs]), and then the jack hole extended within the limestone bedrock to a total depth of approximately 63 feet bgs. The jack hole begins 10 feet 8 inches below the main floor level at the base of the elevator shaft. A break in the 24- inch steel casing was observed at 15 feet below the shaft floor. A schematic drawing of the elevator shaft, jack hole, and casing construction are illustrated on Figure 3.

2. Non-Emergency Immediate Actions

During the Elevator 8 replacement activities, a petroleum odor was reported on 30 March 2017 from within the elevator pit, specifically from the elevator jack hole as the existing metal casing was being removed. Master Lock immediately stopped replacement work pending additional investigation. A sample of the torpedo sand collected from within the jack hole was submitted for laboratory analyses. Analytical results reported detections of DRO at a concentration of 23,800 milligrams per kilogram (mg/kg) and chlorinated volatile organic compounds (VOCs), which are likely associated with the Former Vapor Degreaser Area. On 6 April 2015 Master Lock notified the Wisconsin Department of Natural Resources (DNR) of a potential release based on the odors reported during the Elevator 8 upgrade activities as well as laboratory analytical results (Appendix A). The timing, duration, and quantity of the release are unknown.

Removal of the remaining torpedo sand via vacuum excavation began on 27 April 2015. On 28 April 2015, a sample of the torpedo sand was collected for screening and waste characterization purposes and submitted to the laboratory for analysis of TPH- DRO and Total Characteristic Leaching Procedure (TCLP) VOCs. VOCs were not reported at concentrations greater than laboratory reporting limits, and TPH-DRO was detected in the torpedo sand at a concentration of 3,700 mg/kg.

During replacement activities, the existing jack-hole was determined not to be plumb, so the broken section of steel casing was removed and the hole was filled partially with concrete so that the hole could be re-drilled, via cable-tool methods, along a straight path. During this process, slurry material consisting of a mix of concrete, limestone bedrock, and groundwater, was removed from the hole and placed in drums for proper off-site disposal. A sample of the slurry material (Sample ID “Concrete Elev. 8”) was submitted for laboratory analysis of TPH-DRO and TCLP VOCs. TCLP VOCs were not detected at concentrations greater than laboratory reporting limits, and TPH-DRO was detected at a concentration of 285 mg/kg. A sample of the water decanted from the slurry material was also collected and submitted for laboratory analysis of total metals and VOCs. Chlorinated VOCs were detected in the water sample at concentrations in excess of DNR Enforcement Standards (ES) and/or Prevention Action Levels (PALs). The chlorinated VOC and metal impacts in groundwater are being addressed under a separate BRRTS Case #02-41-579361, Former Vapor Degreaser Area.

On 18 May 2015, a sample of groundwater that had accumulated within the newly re-drilled hole was collected and submitted for laboratory analysis of VOCs and TPH-DRO. The groundwater sample did not contain any VOCs other than chlorinated VOCs (i.e., cis-1,2-dichloroethene, trichloroethylene [TCE], and vinyl chloride), and TPH-DRO was detected at a concentration of 5.64 milligrams/liter (mg/L).

A new 30-inch steel casing was then driven about 1 foot deeper than the top of the break point of the lower casing, approximately 15 feet below the pit floor. The soil from the annual space inside the 30- inch casing was removed and placed in drums for proper off-site disposal. A sample of the soil (Sample ID “30 Diam Soil Elev. 8”) was collected on 16 June 2016 and submitted for laboratory analysis of TPH-DRO and TCLP VOCs for waste characterization. TPH-DRO was detected at a concentration of 622 mg/kg.

Analytical results for the sampling activities summarized above are presented in Tables 1 and 2 and on Figures 4 and 5, and laboratory analytical reports are included in Appendix B.

Twelve drums (approximately 3 cubic yards) of DRO impacted torpedo sand were disposed of off-site under a non-hazardous waste manifest by Enviro-Safe Resource Recovery at Convanta Indianapolis, Indiana. In addition, 56 drums of slurry material and soil generated during installation of the new casing were disposed of off-site by Waste Management under a non-hazardous waste manifest at Orchard Ridge RDF in Menomonee Falls, Wisconsin. Waste disposal manifests are included in Appendix C.

Groundwater and decanted water from the slurry drums were treated through the Master Lock wastewater treatment system to remove any residual oils prior to discharge to the municipal sewer system. A notice of intent to discharge was submitted to the Milwaukee Metropolitan Sewerage District (MMSD) on 22 June 2015 and was approved by the MMSD on 29 June 2015.

2.1 SUMMARY OF SITE INVESTIGATIONS AND DNR CORRESPONDENCE

In response to the release reported on the 6 April 2015, DNR replied with a letter dated 7 April 2015 (Appendix D) notifying Master Lock of the legal responsibilities and requirements of how to proceed, including submittal of a consultant verification letter and preparation and submittal of a Site Investigation (SI) Work Plan.

The Site Investigation (SI) Work Plan, prepared to investigate potential contamination within the vicinity of Elevator 8 in accordance with requirements provided in WAC Chapter NR 700, was submitted to the DNR on 4 June 2015. Following approval of the SI Work Plan on 11 June 2015 and the SI Work Plan Amendment on 17 July 2015, SI activities were conducted in July and August 2015 followed by Supplemental SI (SSI) activities in November 2015, January 2016, and March 2016. However, because of utilities and plant operations, detailed further in Section 2.3, investigation of soils within the immediate vicinity of Elevator 8 was not possible.

The SI Report was submitted to the DNR on 9 December 2016 summarizing the findings of the SI and SSI activities. The findings of the SI report indicated chlorinated VOCs, polycyclic aromatic hydrocarbons (PAHs), and metals were detected in surface and subsurface soils at concentrations in excess of applicable Industrial Direct-Contact Residual Contaminant Levels (RCLs) and/or Site-Specific (ES-Based) Soil-to-Groundwater Standards. Further, concentrations of chlorinated VOCs and metals were detected in groundwater in excess of ES and/or PALs, and TCE and naphthalene were detected in indoor air samples at concentrations greater than their applicable Indoor Air Vapor Action Levels (VALs).

On 28 March 2017, the DNR responded to the SI Report with a comment letter, included in Appendix D, requesting an additional and separate evaluation of the Elevator 8 petroleum impacts from the chlorinated VOC and metal impacts, which are likely associated with former vapor degreaser tanks and other operations at the Site. To address the DRO contamination, the DNR recommended the following:

 Provide additional information to the DNR about the Elevator 8 repair work, the discovery of the DRO contamination, the management of the impacted “torpedo sand,” and whether there was any indication that impact was found outside of the elevator support containment area. This information is provided within the relevant sections of this report.  Evaluate that information and any subsequent soil/groundwater samples relevant to the Elevator 8 area to provide information regarding whether there was a discharge outside the elevator support containment area, and make a specific recommendation for the appropriate closure or resolution mechanism for DRO contamination.

The DNR then provided the possible options for resolution:

A. If the evaluation of information indicates that the contamination was confined to the torpedo sand and released to the soil outside the elevator shaft and the impacted torpedo sand volume was determined to be insignificant and therefore not removed, then “No Action” in accordance with WAC NR 716.05(2)(a) could be requested. B. If the evaluation of information indicates that the DRO contamination was apparently contained to the torpedo sand and not released to soil outside the elevator shaft, and the contaminated torpedo sand volume removed for disposal was less than 100 cubic yards, then a “No Further Action” in accordance with WAC NR 708.05(3) and WAC NR 708.09 could be requested. C. If the evaluation of information indicates that the DRO contamination was not contained to the torpedo sand, but was likely released to the surrounding soil, but structural impediments prevent a complete investigation of the extent of contamination in the area adjacent to the elevator, then a full case closure with residual contamination and structural impediment continuing obligation in accordance with WAC NR 726 could be requested.

On 26 April 2017, a meeting between the DNR, FBHS, and Haley & Aldrich was conducted at the DNR offices in Milwaukee, Wisconsin to discuss their 28 March 2017 comment letter. As a result of the meeting, the DNR believes that the impacts associated with Elevator 8 (petroleum) are minor and can be closed under the provisions outlined in WAC NR 708.05(3) and WAC NR 708.09 (Option B identified above) with no additional assessment required. The DNR requested that a new Discharge Notification be submitted to generate a separate case number for the chlorinated VOC and metal impacts detected in the vicinity of Elevator 8, the former vapor degreaser, and Clark Street corridor (the Former Vapor Degreaser area - BRRTS Case #02-41-579361).

3. Conceptual Site Model

This section provides a summary of relevant Site information including physical setting, investigation limitations, impacted media, exposure pathways and receptors specific to DRO impacts in the Elevator 8 area

3.1 PHYSICAL SETTING

3.1.1 Site Geology

The soil profile encountered beneath the asphalt paving, landscaping materials, and associated sub- base/fill materials, includes fill material of poorly-sorted, black, gray, and brown mixture of gravel, sand, cinders, silt, and clay. The glacial till underlying the fill is composed of gray to brown lean clay with variable amounts of sand, pebbles, and cobbles. Horizontal groundwater-bearing seams composed of interbedded silt, sand, and gravel were encountered in the till, which are believed to be not-well- interconnected, but are conduits for groundwater flow and potential contaminant transport. The glacial till overlays a lodgement till basal unit of hard interbedded gravel, sand, and silt encountered at approximately 28 to 40 feet bgs. Depth to the Silurian dolomite bedrock was reported to be approximately 45 feet bgs; however, the localized presence of this shallow bedrock material may represent a glacial erratic or a pinnacled bedrock surface.

3.1.2 Hydrogeology

During the SI and SSI, saturated conditions in the glacial till were encountered within non-contiguous sand seams between approximately 17.5 and 29 feet bgs. Shallow groundwater monitoring wells, completed within the glacial till, were screened to intersect these water-bearing sand seams. Saturated conditions were either not encountered within the lodgement till and bedrock material, or could not be determined during drilling due to the introduction of water to facilitate roto-sonic drilling in these hard materials. Deep wells were screened and set at depths based on where groundwater was observed to be entering the hydraulic jack-hole at Elevator 8 (50 to 60 feet bgs). Groundwater elevation data were collected from shallow monitoring wells intersecting the glacial till, ranging in depth from approximately 20 to 30 feet bgs. Within the deep monitoring wells, depth to groundwater ranged from approximately 55 to 60 feet bgs.

A groundwater contour map, included as Figure 6, based on 12 September 2017 groundwater elevation data, indicates shallow groundwater flow in this area of the Master Lock facility is to the northeast at a hydraulic gradient of approximately 0.06 feet per foot (ft/ft). Groundwater flow direction for the deep wells could not be accurately determined with the amount of data available (i.e., only two groundwater elevation points); however, deep groundwater appears to also have an easterly flow component.

3.1.3 Topography

Topographically, the Site is generally flat with a slight slope to the east. Site elevation is approximately 681 feet above mean sea level.

3.1.4 Surface Water

Surface water is conveyed towards multiple catch basins located throughout the parking areas. These catch basins discharge to the City of Milwaukee combined sewer system. The nearest surface water body, a recreational lake at Washington Park, is located approximately one-mile southwest of the Site.

3.2 INVESTIGATION LIMITATIONS

Access for subsurface investigation at the Site is highly restricted because of multiple physical limitations including the following:

• Subsurface utilities inside the facility buildings and within Clark Street (and associated parking areas) are densely spaced and pose safety concerns for drilling activities, as well as potential interruption to facility operations (Figure 4); • Access to the inside spaces of the facility is limited due to restricted overhead clearance of access doors, narrow aisle widths, operational and immovable equipment locations (e.g., large stamping presses in Building 14), and low clearance ceilings; • Open areas around in the facility are high-traffic areas used to transport materials and parts through the plant via fork-lift and for staging/storing of parts, supplies, tooling, etc.; and, • Local/regional geology, as described in the previous Section, limits the ability to achieve target depths in the subsurface using smaller drill rig technologies such as direct-push. Smaller rigs are required inside the facility due to the access restrictions mentioned above.

The above access restrictions meet the definition of Structural Impediments in accordance with WAC NR 726.15. A photographic log has been included as Appendix E to further highlight some of the access restrictions listed above. Additionally, a floor plan for the Master Lock facility is included in Appendix F to show the locations of internal features and equipment in the vicinity of the Elevator 8 area.

3.3 SOURCE AREA AND IMPACTED MEDIA

The source area of the DRO impacts has been identified as the former hydraulic jack for Elevator 8. As explained in Section 2, elevated DRO impacts were detected in samples collected from the torpedo sand in the jack-hole. There source materials were removed from the jack-hole and properly disposed off- Site. The old hydraulic jack was also replaced with a new jack within a PVC containment liner. Therefore, future impacts to surrounding soils and groundwater from a continuing source or from releases from the new hydraulic jack are unlikely.

The subsurface soil conditions surrounding Elevator 8 have been evaluated via four surface soil (0 to 4 feet bgs) samples and 11 subsurface soil samples collected from soil borings during the SI and SSI sampling program described in Section 2.1. In addition to other analyses including VOCs and metals, these samples were analyzed for TPH-DRO and gasoline range organics (GRO). Soil analytical results for TPH-DRO are summarized in Table 1 and on Figure 4. Low-level concentrations of TPH-DRO were detected at concentrations greater than laboratory reporting limits in the following soil borings:

 HA-SB-01D (0 to 4 feet): 340 mg/kg;  HA-SB-01D (6 to 7 feet): 154 mg/kg;  HA-SB-01D (16.5 to 17.5 feet): 3.06 mg/kg;  HA-SB-01D (43 to 44.7 feet): 22.7 mg/kg;  HA-SB-02D (56 to 58 feet): 6.48 mg/kg;

6  HA-SB-03D (17 to 19 feet): 22.2 mg/kg;  HA-SB-03D (35 to 36 feet): 19.6 mg/kg; and  HA-SB-03D (40 to 42.5 feet): 4.15 mg/kg.

As stated previously, because of utilities and plant operations, investigation of soils within the immediate vicinity of Elevator 8 were not possible. The maximum detections of TPH-DRO in soil were in soil samples collected from HA-SB-01D (0 to 4 feet and 6 to 7 feet bgs) listed above. This soil boring is located more than 85 feet east of Elevator 8, and the sample intervals were collected at elevations above the elevation of the floor of the Elevator 8 shaft. Therefore, it is unlikely that these DRO impacts are associated with a release from Elevator 8.

The DNR currently does not have regulatory standards applicable to TPH impacts to soil and groundwater, and the analysis is typically used only for screening purposes and waste characterization; therefore, there are no specific exposure pathways or receptors at risk as a result of the TPH impacts in soil. However, in an abundance of caution, several exposure scenarios are evaluated in the sections to follow.

3.4 EVALUATION OF POTENTIAL EXPOSURE SCENARIOS

3.4.1 Land Use

The Master Lock property is currently zoned for heavy industrial use and has been used for industrial purposes since the late 1800s. The Site is located in an active manufacturing area of the Master Lock facility, shown on Figure 2, and is highly probable that future land use will continue to be industrial; therefore, residential exposure pathways and receptors are not applicable to the Site. The Site, including the Elevator 8 source area, are secured and access is monitored by Master Lock; therefore, trespassers are also not likely receptors.

3.4.2 Groundwater Use

No groundwater is currently extracted and used for on-site purposes, and groundwater use is not expected to change in the future. As such, on-site groundwater use is not believed to represent an exposure pathway. In addition, potable water is supplied to the facility by the Milwaukee Water Works. A search of the Wisconsin Geological and Natural History Survey’s water-supply well records database did not identify any water supply wells within 1,200 feet of the Site. Private well use for potable water supply is prohibited by the City of Milwaukee and is also restricted for lawn irrigation and other non- potable uses. As such, there are no known groundwater receptors near the Site if impacted groundwater were to migrate off-site; thus, this is not believed to be a complete exposure pathway for the Site.

3.4.3 Direct Contact

As shown in the aerial photograph in Figure 2 and photographs included in Appendix E, the majority of the Master Lock facility is covered by asphalt pavement (parking areas) and concrete building slabs, thus, impeding direct contact with soil (including accidental ingestion of soil, dermal contact with soil, inhalation of fugitive dust). Therefore, direct contact exposure pathways for industrial workers are incomplete. Direct contact is a potentially complete exposure pathway for excavation/utility worker; however, toxicity and exposure risks associated with any TPH impacts in the subsurface would be evaluated based on other analyses including VOCs and PAHs.

4. Conclusion

Haley & Aldrich has prepared this Final Report to demonstrate the Elevator 8 DRO release meets the requirements of a non-emergency immediate action as defined in WAC NR 708.05(3) and to request a No Further Response Action for Case #02-41-563540 using the provisions outlined in WAC NR 708.09. The DRO release meets these requirements based on the following:

 In accordance with WAC NR 706, Master Lock responded to immediately after discovery of the DRO release. The timing, duration, and quantity of the release are unknown.  The source of DRO impacts reported during the replacement of the elevator jack were identified as the torpedo sand, which was removed for off-site disposal; thus, the release and associated source materials have been addressed through non-emergency immediate action.  The remedial response did not result in the excavation and disposal, treatment, or storage of more than 100 cubic yards of contaminated material.  Review of existing analytical data from SI and SSI activities conducted at the Site and evaluation of potential exposure pathways and receptors demonstrate that residual DRO impacts associated with Elevator 8 does not pose an imminent threat to public health, safety, or welfare.  Access for subsurface investigation at the Site was highly restricted because of multiple physical limitations and meet the definition of Structural Impediments in accordance with WAC NR 726.15.

Based on the information presented in herein, and summarized above, the Elevator 8 DRO Release Area does not pose an unacceptable risk to human health or the environment and meets the provisions outlined in WAC NR 708.09, No Further Response Action. Therefore, no additional assessment or remediation activities are warranted, and on behalf of Master Lock and FBHS, Haley & Aldrich respectfully requests a No Further Response Action the Site
