SWMU 30 – Former Incinerator Area

This unit consists of an inactive incinerator, formerly used to burn contaminated fuels, waste oils, and sludges. An incinerator on this site was reportedly dismantled and removed in 1983, and the present incinerator was built at that time. The 1993 follow-up inspection found that a 500-gallon UST associated with this unit was being removed. The Navy collected subsurface soil samples which indicted the presence of total recoverable petroleum hydrocarbon. Therefore, an RFI for soils was required. Based on the results, groundwater investigations may be required.

Status

• RFI work plans were approved in 1995.
• Sampling indicated that the soil posed no significant human health risks. Subsurface soils were removed to the PREQB clean up level of 100 ppm during UST removal. Residual, low level groundwater contamination is present.
• EPA comments on the initial investigations requested additional work.
• A work plan for additional investigations was submitted to, and subsequently approved by the EPA. The additional investigations were conducted in June 1999.
• The Draft Phase II RFI Report was submitted in December and, following agency comments, the Final Phase II RFI Report was submitted in February 2000.
• The RCRA 7003 Administrative Order on Consent recommends the Determination of Corrective Action Complete With Controls for the Former Incinerator Area.
• Corrective Action Complete with Controls as stated in the 1/29/07 RCRA § 7003 Administrative Order on Consent.
