Background
The City of Rochester is initiating the environmental cleanup of property at 62-64 Scio Street. The project is part of the City's 2010 Brownfield Cleanup Grant from the United States Environmental Protection Agency (EPA). The site, currently vacant and located in the city’s desirable East End District, is owned by the City of Rochester, and measures approximately 55 ft X 200 ft (~0.25 acres).
Formerly, a 22,000 square foot, two story, brick building constructed around 1920 occupied the site. The building was mainly used as a warehouse from the date of construction, until approximately 1990. The City of Rochester took ownership of the property in 1996, at which time the building was mainly used as a storage unit until it was demolished in November 2002. It has remained vacant since demolition.

The City Facilitates Storage Tank Closure and Interim Cleanup
Several environmental investigations were conducted from 1995 to 2006 to evaluate site conditions as part of the City's redevelopment plans for the site. In August, 2006, one (1) 2,000 gallon petroleum underground storage tank (UST) was excavated and removed from the site. The tank contained approximately 415 gallons of water and approximately 1 ton of concrete. The tank was visibly damaged and petroleum impacted soils were observed beneath the tank upon its removal. The City contacted the New York State Department of Environmental Conservation (NYSDEC) and Spill File #0650898 was generated for the site.
Approximately 30 tons of petroleum impacted soils were removed from the tank excavation. Subsequent soil samples were collected and analyzed for the presence of volatile and semi-volatile organic compounds (VOCs and SVOCs) and heavy metals. Laboratory analysis indicated that residual contamination exists at the site.
In 2007, three (3) groundwater monitoring wells were installed to evaluate petroleum impacts on groundwater at the Site. Laboratory results indicated that VOCs in groundwater were present above regulatory guidelines in wells located on the eastern and southern portions of the Site.
Based on the preliminary investigation results, petroleum impacted soil and fill material are still present across the Site ranging from 6 to 12 feet below ground surface, which require remediation. Remediation of groundwater impacts at the Site also appear to be necessary.
Analysis of Brownfield Cleanup Alternatives
An Analysis of Brownfield Cleanup Alternatives (ABCA) was conducted by the City, comparing the feasibility of four (4) remedial strategies for Site cleanup. Based on the ABCA, the following remedial approach has been selected:
- Complete a targeted source removal program to remove the remaining grossly contaminated soil and fractured shallow bedrock from specified areas of the Site;
- Aggressively dewater the subsurface to remove additional contaminant mass from the Site;
- Perform groundwater monitoring for petroleum Volatile Organic Compounds (VOCs) and Semi-Volatile Organic Compounds (SVOCs) to evaluate post-soil source removal Site conditions;
- Complete a remedial design investigation;
- Install a groundwater remediation system for in-situ remediation of groundwater;
- Conduct one (1) year of quarterly groundwater monitoring, subsequent to installation of the oxygen injection system.
The ABCA will be available for public review and comment for 30 days. All public comments received will be addressed and a Action Memo will be publicized. A Corrective Action Plan (CAP) to implement the approved remedial approach will be completed following the publication of the Action Memo.
Public Information Plan
A Public Information Plan (PIP) has been developed to provide the public with Project information, and the City and State Project Manager’s contact information.
