New York State Department of Environmental Conservation (DEC) is reviewing cleanup documents for the Former Mobil Service Station 99-MST ("site") located at 979 Main Street, Buffalo, Erie County. Please see the map in Site Location. Documents related to the cleanup of this site can be found at the location identified below under Where to Find Information.

How to Comment

DEC is accepting written comments about the proposed Remedial Investigation and Interim Remedial Measure (IRM) work plan for 30 days, from August 29, 2012 through September 29, 2012. The proposed plan is available for review at the location identified below under Where to Find Information. Please submit comments to the project manager listed under Project Related Questions in the Who to Contact area below.

Draft Interim Remedial Measure Work Plan

An IRM is a cleanup activity that may be performed when a source of contamination or exposure pathway (the way in which a person may contact contamination) can be effectively addressed without extensive investigation and evaluation.

The draft IRM work plan identifies cleanup activities that include:

  • Installing sheet pile around the contaminated area;
  • Excavation and off-site disposal of contaminated soils;
  • Recovery, treatment and discharge of contaminated groundwater to the Buffalo Sewer Authority system under terms of a permit.

DEC is conducting a public comment period because the IRM is likely to represent a significant part of the cleanup for this site.

Highlights of the Remedial Investigation

Before Remediation: Former Mobil Station site
Before Remediation: Former Mobil Station site

The remedial investigation has several goals:

  1. Define the nature and extent of contamination in soil, groundwater and any other parts of the environment that may be affected;
  2. Identify the source(s) of the contamination;
  3. Assess the impact of the contamination on public health and the environment; and
  4. Provide information to support the development of a proposed remedy to address the contamination.

Next Steps

DEC will consider public comments, revise the plan as necessary and approve the IRM work plan in consultation with New York State Department of Health (DOH). The approved work plan will be made available to the public (see Where to Find Information below). After the work plan is approved, the activities detailed in the work plan will be implemented. Upon completion of the work, a Construction Completion Report will be prepared that documents the activities that were performed.

DEC will keep the public informed throughout the investigation and cleanup of the site.

Background

Before Remediation: Former Mobil Station site
Before Remediation: Former Mobil Station site

Location:
This site is located at 979 Main Street in the City of Buffalo. The site borders with Goodrich Street on north, High Street on south and a parking lot for the Buffalo General Hospital on the east. The land use in the project area is characterized as urban mixed use, primarily commercial and community services. The community services include public and private medical and hospital facilities.

Site Features:
The site consists of four vacant parcels and is approximately 1.7 acres in size.

Current Zoning/Use:
The site is located within the commercial zoning district.

Historical Uses:
Exxon Mobil and its predecessors operated a gas station from approximately 1940s to 1982. The gas station building was demolished in 1982. Four underground storage tanks (USTs) were removed in 1981 (4000 gal, 3000 gal), 1982 (6000 gal), and 2007 (1000gal). Other previous businesses at the site included an auto repair shop, medical and dental departments, restaurant and a motel.

Site Investigations:
Several investigations were conducted under the Spills Program from 1988 to 2010. The investigations have shown the presence of lighter non-aqueous phase liquid (LNAPL) or product (gasoline) and elevated levels of petroleum hydrocarbons in soil and groundwater at the Site. An interim treatment system consisting of a high vacuum extraction (HVE) and Air Space (AS) system to remove petroleum products was operated between 1998 and 2008.

Site Geology and Hydrogeology:
Overburden soils in the area consist primarily of fill material at the ground surface. Geotechnical boring logs collected from the site in 2010 indicate that fill material such as sand, gravel and bricks varies in thickness from two to 10 feet across the site. Soil underlying the fill is comprised of interbedded sands and silts that are brown to olive-brown in color. Overburden soils are underlain by the Onondaga Limestone (bedrock), which is at approximately 100 feet below ground surface (bgs). The groundwater is approx. 24 feet bgs and flows towards northeast.

Additional site details, including environmental and health assessment summaries, are available on DEC's website .
