Background

NWIRP Bethpage, New York was a Government-Owned Contractor Operated (GOCO) facility located in Nassau County on Long Island, approximately 30 miles east of New York City. Established in 1942 for research prototyping, testing, design engineering, fabrication and primary assembly of military aircraft, Northrop Grumman Corporation (NGC) operated the facility until it closed in September 1998. The NWIRP was located within the secure portion of the NGC complex, and between the Navy and NGC totaled approximately 605 acres.

The 105-acre main parcel included the former Northrop Grumman main aircraft manufacturing building (Building 03-01), ancillary facilities associated with Plant 03, as well as all of the facilities designated as Plants 10 and 17. Plant 10 consisted of a former quality control laboratory building (Building 10-01) plus associated support structures in the southwestern part of the main parcel. Plant 17 consisted of a cluster of six warehouses in the northwestern part of the parcel (Plant 17 North) and a cluster of ten warehouses in the southeastern part of the parcel (Plant 17 South).

In 1998, the land was returned to Navy control. Under special legislation, NWIRP Bethpage was to be conveyed to Nassau County, New York for economic redevelopment. NWIRP Bethpage originally included a main parcel of approximately 105 acres and a separate parcel of approximately 4.5 acres located to the north of the main parcel. The parcel to the north (Plant 20) of the main parcel that formerly housed a vehicle maintenance facility was transferred to Nassau County on December 10, 2002.

Another cluster of buildings, designated by NGC as Plant 05, was formerly owned by the Navy but situated on land owned by NGC. Plant 05 was located south of the main parcel. The Navy also transferred the Plant 05 buildings to Nassau County on December 10, 2002.

On February 26, 2008, the Navy transferred 96 acres of the 105-acre main parcel to Nassau County and leased the remaining 9 acres to Nassau County. Two of the Navy’s Environmental Restoration (ER) sites were located on the 96-acre parcel that was transferred, ER Site 2 – Recharge Basins and ER Site 3- Salvage Storage Area. These sites were determined to not require further environmental investigation or remediation. The 9-acre parcel is being retained by the Navy for environmental investigations and remediation consist of ER Site 1 – the Former Drum Marshalling Area and ER Site 4 – Former Underground Storage Tank area south of Plant 03.

Regulation History

NWIRP Bethpage was a GOCO facility leased by the Navy to NGC. When NWIRP Bethpage was operational it was considered to be a large quantity generator of hazardous waste and was classified as a Treatment, Storage, and Disposal (TSD) facility, for storage of hazardous wastes beyond 90 days. Due to this designation, NWIRP Bethpage was under a federal Hazardous and Solid Waste Amendment of 1984 permit issued as part of the Resource Conservation and Recovery Act (RCRA) in which the Navy was identified as the property owner and Northrop Grumman was listed as the operator. Due to its TSD designation, NWIRP Bethpage was also subject to NYSDEC’s Permit to Operate a Hazardous Waste Management Facility under state implementing regulations 6 NYCRR Part 373. In August 2007, NYSDEC removed the 96-acre parcel from the 373 Permit, including ER Sites 2 and 3. The 9-acre parcel retains the RCRA permit, with requirements limited to corrective action components only.

NWIRP Bethpage is also classified as an “Inactive Hazardous Waste Disposal Site” under NYSDEC 6 NYCRR Part 375 (Registry No. 1-30-003B). The Part 375 program is a risk-based program and closely parallels the United State Environmental Protection Agency’s (USEPA) Superfund Program. NWIRP Bethpage is not on the National Priorities List (NPL). The four sites are addressed under the Navy’s ER program.
