Resource conservation and recovery act ground-water monitoring projects for Hanford facilities: Progress report, January 1--March 31, 1989

Abstract

XV i i A RCRA Part A application for the Hanford Site has been submitted to the U.S. Environmental Protection Agency (EPA) Region 10 and the Washington State Department of Ecology (hereafter called Ecology). Currently, the Hanford Site is operating under RCRA interim status. Interim-status standards applicable to groundwater monitoring activities are discussed in 40 CFR 265.90 to 265.94, and WAC 173-303-400, and are applicable to Hanford Site facilities until final administrative disposition of Part B permit or closure application(s). Hanford interim-status groundwater monitoring projects are conducted as either background, indicator parameter, or groundwater quality assessment monitoring programs (40 CFR 265). A background monitoring program involves I.
