• “Section 3.0 Removal Action” of the Work Plan is modified by replacing the first paragraph with the following: “Even though the Site is zoned General Industrial District rather than Residential, this Work Plan proposes a removal action consistent with the protections for residential properties by conforming to the EPA’s Superfund Lead-Contaminated Residential Sites Handbook (OSWER 9285.7-50, August 2003). The Work Plan will remove exposed soils to a depth of one foot bgs in all areas that are not capped by intact asphalt or concrete or covered by a current or historic building foundation or pad, and will remove exposed soil to a depth of two feet bgs in an area not to exceed 14,000 square feet. The general location of this two-foot excavation area is shown on Figure 3 — revised (8/30/2012) and the exact location will be depicted after completion of all Work Plan activities in a surveyed as-built figure.

• "The area identified as Phase 3 work will be divided into two components as identified on Figure 3 — revised (8/30/20 12). The eastern portion of that Phase 3 area will be excavated to a depth of one foot, backfilled, and capped with a six-inch asphalt cover (four inches of base and two inches of compacted asphalt). The western portion of that Phase 3 area will not be excavated, but the existing asphalt surface will be restored in-place with a tack layer, a leveling course of asphalt and a new surface course of two inches of compacted asphalt as a final cover, except that a former utility corridor (approximately four feet wide) through the existing asphalted area will be excavated to a depth of one foot and backfilled prior to placement of the new cover, and a small portion at the southwest corner of the Phase 3 area that is not covered with asphalt will be excavated to a depth of one foot and restored with topsoil and revegetated. The location of these areas are shown on Figure 3 - revised (8/30/2012).

• "Within the area identified as Phase 1, NL will excavate that portion of the Phase 1 area at the southern side of the site to the curbline as shown on Figure 3 - revised (8/30/12), which is presumed to be consistent with the curbline of the properties to the east and west of the site, but not any part of the active roadway. NL will excavate those open areas of the Phase 1 and Phase 2 areas between the Fleetpride building and the fenceline behind that building to a depth of one foot to the extent that those areas are machine accessible, but will not disturb the building foundation, covered surfaces, equipment, or utilities in this area, or the soil at the fenceline. Work in the Phase 1 area will not disturb or otherwise jeopardize the integrity of the underground oil/water separator west of the FleetPride wash rack area.”

• Although the Work Plan and Figure 3 — revised (8/30/2012) retain the terms Phase 1, Phase 2 and Phase 3, the work at the Site, with the above-mentioned modifications to accommodate ODM, will be carried out by the project contractor to most effectively use the available resources. Therefore, the work may not move from one Phase area to the next as originally contemplated. This became necessary due to scheduling constraints with the asphalt subcontractors and in order to complete the project within the original schedule. The revised Figure 3 may be viewed on the project website at ttp://www.epaosc.org/formercarterwhite.

On August 27, excavation work started.  As described in the Work Plan, soil is excavated and consolidated into 250 cubic yard stockpiles within the secured Area of Contamination, as delineated by NL and approved by NDEQ.  A water truck is maintained on-site, and visible dust emissions from stockpiles are low, despite substance particulate contributions caused by off-site truck traffic on roadways surrounding the Site. 

On August 29, stockpile waste characterization sampling began.  Sampling was conducted by ENTACT personnel in accordance with the procedures specified in the Work Plan (i.e., four-part composite). 

On August 31, excavation, on-site soil consolidation, and stockpile waste characterization sampling was completed.  Initial rounds of waste characterization data were received, indicating high leachability with TCLP lead concentrations ranging from 30 mg/L - 100 mg/L.  Waste stabilization treatment will begin in the next reporting period. 

2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)

An Administrative Settlement Agreement and Order on Consent CERCLA-07-2012-0053 was established between NL, the EPA and Moweco, Inc., effective August 7, 2012.  ODM is a property owner and has provided access to complete the removal action as well an Environmental Covenant for implementation of Post-Removal Site Controls.  Moweco filed a similar environmental covenant for the parcels under their ownership.

2.1.4 Progress Metrics

As of the close of this reporting period, no waste has been shipped off-site.  Approximately 400 cubic yards of contaminated soil has been excavated and stockpiled awaiting treatment.
