The Order provides for the performance of a removal action by Respondent at the Computer Circuits Site (the Site). Respondent to the Order is the current owner of the Site property.
The Order calls for the construction and operation of both a soil vapor extraction (SVE) system, and a sub-slab depressurization system at the Site. Under the Order, operation and maintenance of the SVE system and sub-slab depressurization system shall continue until six months after the later of the following: (1) concentrations of TCE in indoor air do not exceed 0.36 ug/m3 or, if approved by EPA, the Site-specific indoor air background level for TCE; and (2) concentrations of TCE in representative soil-gas samples at the intake of the SVE and the sub-slab depressurization systems do not exceed 36 ug/m3 and 3.6 ug/m3, respectively.
The Order also calls for the reimbursement of response costs incurred by EPA in overseeing Respondent's implementation of the Work required by the Order. The record of decision is expected within a calender year, and the removal work required under the Order addresses contamination identified in the RI.
