Scott Aviation Area 1 Brownfield Cleanup Program Site

Site Number C915233

DEC is accepting written comments about the proposed cleanup plan for 45 days, from October 13, 2015 through November 26, 2015.

Digital Files


Location: The Former Scott Aviation Area 1 Site consists of approximately 1.7 acres of a 25 acre parcel at 225 Erie Street in the Village of Lancaster, Erie County. The BCP site is bounded by an asphalt parking lot to the north, the AVOX Plant 1 building to the east, the Norfolk Southern Corporation railroad to the south, and residential property to the west.

Current Zoning/Land Use: The site is an active manufacturing facility, and is zoned for industrial use. The proposed future use of the site is commercial or industrial. The general land use of the area is commercial, light industrial and residential. The nearest residential property is located about 100 feet from the boundary of the BCP site.

Historic and Current Use: The Scott Aviation facility formerly manufactured respiratory equipment at the Erie Street facility. Plant 1 is currently used as a manufacturing, development, testing and distribution facility for aircraft and military supplied air systems.

Remedial History: In February 2004, a Phase I Environmental Site Assessment (ESA) was completed to evaluate the environmental status of the entire Scott Aviation property (the parcels north and south of Erie Street). During the detailed study of historical aerial photographs, an area of potentially disturbed soil west of Plant 1 was observed.

In March 2004, seven test pits were excavated during a Phase II Environmental Site Investigation (ESI) to investigate the extent of disturbed soil. Residual paint sludge of unknown origin was observed in two of the test pits. The paint sludge was approximately 150 square feet in size. Soil samples contained elevated concentrations of volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs).

In 2005, a removal action was completed to address the elevated VOC and SVOC contamination. The excavation was approximately 14 feet by 18 feet, with depths ranging from approximately 5.5 to 6 feet bgs. Although soil at the base of the excavation exceeded DEC's soil cleanup objectives, additional excavation was not completed as groundwater was encountered in the excavation. In 2006 and 2007, a Preliminary Groundwater Assessment (PGA) was completed to assess the nature and extent of VOCs in groundwater west of Plant 1. Eighteen temporary piezometers were installed during the PGA to monitor shallow overburden groundwater. Groundwater samples collected from these piezometers were contaminated with VOCs, with 18 of these compounds detected at concentrations that exceeded DEC's Class GA groundwater standards.

Samples of deep overburden groundwater were also contaminated with VOCs, but to a lesser degree than the shallow overburden groundwater. The BCP Remedial Investigation (RI) began in December 2010 with the completion of soil borings, the installation of monitoring wells, and the collection of soil, groundwater and vapor samples for chemical analysis. This initial work was completed during the summer of 2010. A Supplemental RI, completed in June 2011, included the installation of additional monitoring wells, groundwater sampling, and an evaluation of a storm sewer system that was located throughout the BCP site.

Site Geology and Hydrogeology: The geology of the BCP site consists predominantly of interbedded silts and clays with discontinuous, fine sand lenses (the shallow overburden zone), overlying a thin, coarser-grained silt, sand, and gravel layer (the deep overburden zone) located immediately above bedrock. Depth to bedrock ranges from 20 to 26 feet below ground surface across the site.

Shallow overburden groundwater elevations show seasonal variability, with average water depths ranging from 2.46 to 7.13 feet below ground surface. Groundwater flow in the northern and central portions of the site is toward an on-site storm sewer system, while groundwater flow in the southern portion of the site is toward the southeast. Deep overburden groundwater elevations also show seasonal variability, with average water depths ranging from 4.11 to 6.94 feet below ground surface. Deep overburden groundwater flow is to the northwest.

Upper bedrock groundwater elevations also show seasonal variability, with water depths in the one bedrock well installed at the site ranging from 6.96 to 10.28 feet below ground surface.

Brownfield Cleanup Program

New York's Brownfield Cleanup Program (BCP) encourages the voluntary cleanup of contaminated properties known as "brownfields" so that they can be reused and redeveloped. These uses include recreation, housing, business or other uses. A brownfield is any real property that is difficult to reuse or redevelop because of the presence or potential presence of contamination. For more information about the BCP, visit DEC's website.
