ENB - Region 2 Notices 4/22/2009

Public Notice

Voluntary Cleanup Agreement

Notice of Availability for Comment

VCP Number: 00540, Con Edison East 115th Street MGP Site, New York, New York

County: New York

Lead Agency: New York State Department of Environmental Conservation (NYS DEC)

Project Title: Availability of Voluntary Cleanup Project Decision Document, Alternatives Analysis Report, and Draft Site Management Plan, Con Edison East 115th Street MGP, New York, New York

Site ID No: V00540

Name of Volunteer: Consolidated Edison Company of New York, Inc. (Con Edison), 31-01 20th Avenue, Long Island City, NY 11105-2048

Project Location: This 5.5 acre site is located on the FDR Drive, south of East 116th Street. A manufactured gas plant (MGP) operated on the site between 1895 and 1936. The MGP came under the ownership of Con Edison, which retains liability for the contamination produced by MGP operations. The site is currently occupied by a school, which was constructed in 1941 and which currently houses the Manhattan Center for Science and Math and the Isaac Newton Junior High School for Science and Math (hereafter referred to as the school).

Brief Project Description:

Assessment of the Site:
Contamination was identified by the Remedial Investigation (RI) of this site, which represents a threat to public health and the environment, requiring a remedial program to address the contamination identified below.

Nature of Contamination: The RI identified the presence of coal tar in the subsurface soil. Contaminants of concerns in the tar include polycyclic aromatic hydrocarbons (PAHs) and the volatile compounds benzene, toluene, ethylbenzene and xylene (BTEX).

Extent of Contamination: Based on the Remedial Investigation Report, significant amounts of MGP tar, a non-aqueous phase liquid (NAPL), are present in the foundation of a former gas plant structure called a "relief holder". This foundation was left behind when the gas plant was demolished, and is now located under the foundation of the school building. Some tar has migrated from this structure into the surrounding soils. Under the school, the area of contamination is confined to the southern portion of the site, but contamination spreads out as it moves to the east. Contamination from the relief holder and other structures has moved through the subsurface eastward under the adjacent Harlem River. The contamination under the river is not exposed on the river bottom, and is covered by at least 14 feet of sediments that are not impacted by the MGP site.

Groundwater in the immediate vicinity of MGP tars has been contaminated by MGP related chemicals. However, groundwater contamination does not extend significantly beyond the extent of tar. Non-MGP related chemicals in groundwater were found in areas west and north-west of the school building.

Extensive soil vapor and indoor air monitoring has been completed. There is no evidence that subsurface vapors are entering the school. However, elevated levels of both MGP related and non-MGP related chemicals were observed in the soil vapor below the concrete floor of the school. These vapors are not entering the school under current conditions.

The Proposed Remedy: Based on the Alternatives Analysis report, the Draft Site Management Plan and the criteria identified for evaluation of alternatives, the Department has selected the remedy for this site, which will include:

Installation of a low permeability subsurface barrier wall along the FDR Drive, to prevent any further movement of coal tar from the site. Tar will be collected and monitored to prevent migration through or around the barrier. Groundwater will be monitored and controlled to prevent groundwater mounding behind the wall.

Excavation of areas outside the school building where significant contamination has been observed at shallow depths. Excavated soil will be transported off-site to an appropriately permitted treatment or disposal facility. All excavation will be completed in a manner which will control dust, vapors or nuisance odors.

Installation of a sub-slab depressurization system beneath the school foundation slab. The system will provide a negative pressure below the building to prevent soil vapor from entering the building in the future.

While the school is in place, further remediation of the site is not feasible. However, if the building's use as a school is either permanently ended, or temporarily suspended (e.g. major renovations), Con Edison will reevaluate alternatives for the site to determine if additional measures can be taken to decrease the volume, toxicity, or mobility of the remaining source material. In addition, there will be a requirement to assess new remedial technologies every 10 years to determine if a remedial technology has become available that could be effectively implemented.

Development of a site management plan which will require proper handling of any soil excavated in the future, require monitoring of groundwater and sediment, and provide for the operation and maintenance of the components of the remedy.

Imposition of institutional controls, in the form of an environmental easement for the site which will require compliance with the site management plan, restrict the use of groundwater, and require periodic certification of institutional and engineering controls. This certification will state that institutional controls and engineering controls are in place and are either unchanged from the previous certification or are compliant with Department-approved modifications and state that nothing has occurred that would impair the ability of the control to protect public health or the environment.

Notice of Acceptance of Final EIS

New York County (Manhattan) - The New York City Planning Commission, as lead agency, has accepted a Final Environmental Impact Statement on the proposed Fordham University Lincoln Center Master Plan. The action involves the proposal by the applicant, Fordham University, to implement the Master Plan for its Lincoln Center campus that would provide approximately 2.35 million square feet of additional gross floor area at this location (1.6 million gross square feet of additional academic and dormitory space and 736,500 gross square feet of new residential space to be built by private developers). Development is expected to occur in two phases with Phase I complete by 2014 and Phase II (full development) complete by 2032.

The proposed project would require a number of discretionary actions from the lead agency, New York City Planning Commission (NYCPC), that would include several special permits, a zoning text amendment, and a number of zoning authorizations. The NYCPC is contemplating modifications to the proposed action that would affect density and floor area, building heights and bulk, parking, ground-floor transparency, the width of sidewalks on Columbus Avenue and West 62nd Street, the entrance stairs on Columbus Avenue and West 62nd Street, and requirements for ground-floor transparency.

Fordham will be also seeking approval by Dormitory Authority of the State of New York (DASNY) for the authorization of the expenditure of proceeds from the State of New York Personal Income Tax Revenue Bond (Education Resolution) program. The bond proceeds will be used to finance the development of the academic buildings in the Master Plan.

On April 10, 2009, the New York City Department of City Planning, on behalf of the New York City Planning Commission as lead agency, issued a Notice of Completion for a Final Environmental Impact Statement (FEIS) for the proposed Fordham University Lincoln Center Master Plan. The FEIS is available upon request from the lead agency and will also be made available for download at: http://www.nyc.gov/html/dcp/html/env_review/eis.shtml. The project is located on the superblock bounded by Columbus Avenue, Amsterdam Avenue, West 60th Street and West 62nd Street immediately south of the Lincoln Center for the Performing Arts on the Upper West Side of Manhattan within Community District 7, New York.
