The information given below is for C828159. Location: The 690 Saint Paul Street site is located in an urban area in the City of Rochester, Monroe County, just north of the intersection of Saint Paul Street and Upper Falls Boulevard. Site Features: The site covers approximately 4.7 acres. The main site features include four buildings. Three of the buildings are interconnected, seven stories tall and made of brick. The fourth building is a metal framed slab on grade structure. These buildings have a total footprint of approximately 89,280 square feet. All of the buildings are at least partially occupied. A paved parking lot is located on the northern and eastern portions of the site. Lawn area and a small playground are on the eastern side of the site. Current Zoning and Land Use: The site is zoned for industrial uses. One of the large brick buildings is occupied by the Rochester City School District and a charter school. The remaining buildings are partially occupied but with significant vacancy. Current uses include a school, light industrial operations, and a workshop for creating theater sets. The site is bound by roads on all sides. Residential, commercial and vacant properties are located across from the site. Past Use of the Site: The site was developed prior to 1875 and was primarily used for residential purposes until the 1920s. From around 1920 until the late 1960s, the property was owned and operated by Bausch & Lomb (B&L) to manufacture lenses and other products. A foundry was also present near the northeast corner of the site. Since the early 1970s, the site has been used for storage as well as commercial and light industrial activities. Prior uses that appear to have led to site contamination include underground storage tanks (USTs) that may have leaked. These tanks appear to have contained chlorinated solvents including trichloroethene (TCE) and petroleum products including gasoline and fuel oil. In 2002, a 500-gallon UST was removed from the site and contaminated soil was encountered. The contaminated soil was used to backfill the area of the tank removal. In 2008, an investigation was performed to determine the extent of soil and groundwater contamination associated with the 2002 tank removal. The investigation identified an area of petroleum contaminated soil, but did not detect significant TCE soil contamination. The investigation was followed by the excavation of approximately 1,650 cubic yards of petroleum impacted soil and a previously undocumented UST. An area of petroleum impacted soil could not be safely removed because it was close to an underground electric line. Groundwater sample results from 2008 also identified an area impacted by chlorinated solvents, primarily TCE, near Building 14B which was occupied by the City of Rochester School District. The chlorinated solvent impact area did not appear to be associated with the petroleum impacted soils and UST that were removed from the site in 2008. A sub-slab depressurization system was subsequently installed under Building 14B to mitigate the potential for contaminant vapors to migrate through the floor and into the indoor air. Site Geology and Hydrogeology: The ground surface at the site generally slopes to the south and west. The depth to bedrock ranges from less than two feet on the southern portion of the site to twelve feet on the northern portion. The overburden consists of a combination of fill and native soil. Where present, the fill material is up to eight feet thick and includes sand, crushed gravel and brick, construction and demolition debris, foundry sand, cinders, ash, and imported sandy soil. The underlying native soil is primarily a glacial till that is up to ten feet thick. The till contains silt, sand, and gravel in varying amounts. The Decew Dolomite (a type of bedrock) underlies the overburden at the site. The thickness of this unit is generally 8 to 12 feet. The Rochester Shale underlies the Decew Dolomite. The depth to groundwater ranges from approximately four to nine feet below the ground surface. Groundwater generally flows to the west and is likely influenced by the Genesee River Gorge which is approximately 1,000 ft to the west/southwest. The Genesee River in this area is also about 100 ft. below the Site. Although the overall groundwater flow in the overburden is towards the Genesee River Gorge, areas of the site may be influenced by preferential pathways (e.g., subsurface utilities and associated bedding materials). Contaminants of Concern (Including Materials Disposed) Contaminant Name/Type xylene (mixed) trichloroethene (TCE) Site Environmental Assessment Nature and Extent of Contamination: Based upon investigations conducted at the 690 Saint Paul Street site, the primary contaminants of concern migrating off-site include trichloroethene (TCE) and its associated degradation products. On-site investigation activities focused on the eight (8) areas of concern (AOCs) described below: AOC 1: Former Oil House located in the central portion of the site; ACO 2: Former Foundry building located near the northeast corner of the site; AOC 3: Former Agitator Building located along the northern site boundary; AOC 4: A 125.000-gallon above-ground reservoir located on the ground floor of a former manufacturing building; AOC 5: The remaining on-site buildings; AOC 6: All portions of the site not covered by the other AOCs; AOC 7: A former dust collector located in the central portion of the site; and AOC 8: The northwest corner of the site. The on-site results indicated groundwater from AOC 1 and AOC 8 is migrating off-site to the west toward Saint Paul Street. A soil vapor intrusion investigation is being conducted on off-site buildings on the west side of Saint Paul Street. Site Health Assessment People are not drinking the contaminated groundwater because the area is served by a public water supply that is not affected by this contamination. Volatile organic compounds in the groundwater may move into the soil vapor (air spaces within the soil), which in turn may move into overlying buildings and affect the indoor air quality. This process, which is similar to the movement of radon gas from the subsurface into the indoor air of buildings, is referred to as soil vapor intrusion. Environmental sampling at the property boundary of the 690 St. Paul Site indicates that off-site vapor intrusion is a potential exposure pathway that warrants additional investigation.
