Proposed Remediation Plan for the Grumman Aerospace Site Released for Public Comment
Public Comment Period for Bethpage Area Site Runs Through June 30, Public Meeting & Information Sessions to Be Held
The proposed clean-up plan for the Northrop Grumman - Bethpage site (Former Grumman Settling Ponds) is now available for public comment, the New York State Department of Environmental Conservation (DEC) announced today. The public comment period on the Proposed Remedial Action Plan (PRAP) will run through June 30, 2012 with a public meeting on Tuesday, June 12. DEC developed the plan in conjunction with the state Department of Health (DOH).
The public meeting will be held at 7 p.m. at the Bethpage High School located at 10 Cherry Avenue, Bethpage. At the meeting, DEC and DOH staff will describe the contents of the cleanup proposal.
Prior to this meeting, two availability sessions will be held on the PRAP for this site. Availability sessions are more informal presentations where the public can ask project engineers and state health engineers individual questions about remediation plans for the site.
The two availability sessions will be held on June 11 from 7 p.m. - 9 p.m. and on June 12 from 1 p.m. - 4 p.m. The public can arrive anytime between these hours. Sessions will be held at Bethpage Community Center, 100 Grumman Road West.
Public comments on the proposed remediation plan will be accepted at both availability sessions and at the public meeting on June 12.
The goal for the remedial program is to restore the site to pre-disposal conditions to the extent feasible. The remedy proposed for the site includes excavating contaminated soils at Bethpage Community Park, treating some deeper contaminated soils with an underground heating technology, soil vapor extraction and extracting and treating contaminated groundwater both at the park and down gradient of the site.
For soil on-site, the clean-up levels are based on meeting restricted residential Soil Cleanup Objectives in the top 10 feet of soil and removing deeper soils containing PCBs at levels of 50 parts per million (ppm) or more. For groundwater, the goal is to fully contain contamination within the Operable Unit 3 source area at the Park and to remove 90 percent of the contamination leaving the "hot spot" in the plume downgradient of the site. The Wellhead Contingency Plan that was part of Operable Unit 2 is continued to ensure protection of public health and the environment.
The proposed remedy represents the alternative preferred by DEC and DOH to address site contamination. The draft cleanup plan has several goals:
- identify cleanup levels to be achieved;
- summarize other alternatives considered;
- explain why NYSDEC and NYSDOH believe the proposed remedy is the best alternative
- provide a detailed description of the proposed remedy.
The proposed remedy was chosen following a detailed investigation of the site and evaluation of alternatives to address contamination.
The site is listed as a Class 2 site in the State Registry of Inactive Hazardous Waste Sites (list of State Superfund sites). A Class 2 site represents a significant threat to public health or the environment; action is required.
The former Grumman Settling Ponds and associated disposal areas are in the 18-acre Bethpage Community Park. This property was used historically for disposal of various wastes generated by industrial operations in the Grumman industrial complex. These wastes included chromium, PCBs, and volatile organic compounds (chlorinated solvents used for cleaning or degreasing machinery or fabricated parts).
Three significant Interim Remedial Measures (IRMs) have been completed at this site. These include:
- removing contaminated soil by the Town of Oyster Bay in preparation for constructing the new Ice Skating Center;
- installing a soil vapor extraction system by Grumman in the Grumman access road to intercept contaminated soil vapor migrating from the Park; and
- installing a groundwater pump and treat system installed by Grumman in the Grumman access road to intercept contaminated groundwater migrating from the Park.
The Remedial Investigation and Feasibility Study for this site were conducted by Northrop Grumman Corporation under an Order on Consent with DEC.
