are located in Region V the request was forwarded to USEPA Region V. Both facilities were deemed acceptable. The EQ Detroit, Inc. site was last inspected on March 20, 2009. The Wayne Disposal, Inc. site was last inspected on July 29, 2008.

Three different waste streams

Text Box: On July 6, 2009 the Army received approval from the USEPA for the disposal of some of its hazardous waste at two approved hazardous waste facilities: EQ Detroit, Inc . and Wayne Disposal, Inc. The request for approval was sent to USEPA Region II. But since both hazwaste facilities

were generated from excavation at the Former DRMO Yard as follows: hazardous lead and cadmium soil (intended for disposal at EQ Detroit, Inc. in Detroit, MI); PCB soil (intended for disposal at Wayne Disposal, Inc in Belleville, Mi); and

non-hazardous lead soil

(intended for disposal at Cape May County MUA in

New Jersey).

live. ICMs were known to be present in a small (0.5 acre) trapezoidal area located in the former DRMO Yard; these ICMs were the basis for the TCRA (Time Critical Removal Action) in the area. However, during activities associated with implementation of the IRP (Installation Restoration Program) remedy for the site, additional ICMs (a total of 47)

Text Box: The Army provided an interim status report to the USEPA and to the NJDEP on August 10, 2009. The Army called attention to the fact that none of the ICMs (Improved Conventional Munitions)encountered in the original excavation area and in a subsequently added area (referred to as “IRP Excavation Area C”) were

were discovered. The additional ICMs were handled by the UXO (Unexploded Ordnance) team performing the TCRA. Due to the fact that the ICMs from both areas were found to be inert during demolition (determined to be practice rounds) the Army made a decision to change the soil cover thickness from 4 feet to 2 feet and to omit the

erection of a fence around the subject areas. The Army offered the agencies the opportunity for further discussion of the matter in a phone call; no subsequent documentation of agency denial or approval of the change in scope was provided to the RAB.
