Consolidated SPDES Renewals
Project Location: Region 8, Monroe County, Town of Henrietta, 99 Ridgeland Road, 14623
Brief Project Description: The Site is a 1.25 acre parcel which is currently owned by GMC Management Corporation and improved by a 8,425 square foot industrial building constructed in 1967. A 3,000 sq. ft. addition to the building was completed in 2003. It is located in a commercial and light industrial area. Public water and sewers are available in the area and there are no known private drinking water wells or septic tanks.
American Siepmann Corporation (ASC) was a former tenant at the Site from 1983 to 1992. Two of ASCís related corporations also operated at the Site at various times within this same time period. ASC is a distributor of grinding and polishing machines, etch making equipment and related supplies. One corporate relative researched, developed, and manufactured gun barreling manufacturing equipment. The other corporate relative manufactured grinding wheels. Solvents including 1,1,1 trichloroethane ("TCA"), and trichloroethylene ("TCE") were used in these manufacturing processes to clean equipment. The solvent was reclaimed through on-site filtration. In 1993, soil and groundwater chlorinated solvent contamination was discovered along the eastern side of the building and 185 tons of TCE, TCA, and perchloroethene ("PCE") contaminated soil were later removed from the area. Five groundwater monitoring wells were also installed as part of this removal action. Several of these wells indicated the presence of the noted contaminants.
As a result of these findings, Department of Environmental Conservation (DEC) staff determined that additional subsurface investigation was necessary and ASC entered into a Voluntary Cleanup Agreement (VCA) with the DEC to perform such an investigation. The investigation performed pursuant to the VCA included surface soil, subsurface soil, groundwater and indoor air sampling. A continuing source of contamination in the soil was not identified, but groundwater contamination was still present. The highest concentrations of chlorinated VOCs (about 3 ppm, September 2001) were detected in the groundwater beneath the building. The investigation results also indicated that the groundwater contaminants are migrating to the west southwest towards Interstate 390 and Jefferson Road. The indoor air samples did not detect chlorinated solvents.
The Contemplated Use for this site after cleanup is restricted industrial/restricted commercial excluding day care, child care and medical care uses. The proposed remedy for the site is Monitored Natural Attenuation (MNA) with institutional controls (deed restrictions), and sub-slab ventilation. The deed restrictions will restrict the use of the site to the Contemplated Use, prohibit the use of groundwater, require development of DEC approved Soils Management Plans prior to disturbing any soil, and require annual certification that the restrictions are in place and effective.
MNA is considered an acceptable remedy because the investigation results indicated that attenuation processes are currently proceeding at an acceptable rate, the groundwater concentrations are relatively low (up to 3 ppm of chlorinated compounds), a source area in the unsaturated soils was not identified, and aggressive remedial actions underneath the building are not practicable. Site excavation work and contaminated indoor air were identified as potentially complete human exposure pathways. Exposure to site excavation workers will be managed through the deed restrictions. While compounds related to the site contamination were not detected in the air inside the building, a sub-slab venting system will be installed underneath the building. The venting system will pull air from underneath the building and vent it through a pipe to the top of the building. This will prevent contaminated air vapors from entering the building in the future.
The State welcomes public input into this proposed plan. ASC has prepared a Work Plan for Implementation of Monitored Natural Attenuation that explains the proposed plan in more detail. You can review this document, along with the site investigation report, at the locations listed below.

Monroe County - The County of Monroe, as lead agency, has determined that the proposed Sewerage Improvements for the Mill Seat Landfill & Village of Churchville will not have a significant adverse environmental impact. The action involves the design and construction of two pump stations and approximately 8.5 miles of force main and appurtenances to convey leachate and wastewater from Monroe County's Mill Seat Landfill and the Village of Churchville, in the Town of Riga, to the Monroe County Pure Waters' King Road Trunk Sewer near Union Street (NYS Route 259), in the Town of Chili.

Ontario County - The Town of Farmington Town Board, as lead agency, has determined that the proposed Town of Farmington Waste Water Treatment Plan Expansion Project will not have a significant adverse environmental impact. The action involves the complete upgrades and improvements to their 2.1 MGD Wastewater Treatment Plant, which will increase the capacity of the facility to 4.0 MGD. The proposed improvements will replace and/or improve deteriorated, inefficient, and outdated componenets fo the treatment process, and will provide sufficient capacity to meet future demands resulting from growth and expansion of sewer systems serving parts of the Towns of Farmington, Victor and Canandaigua.
