Summary Information
(last updated on: 10/11/2010 7:27:01 AM)
Chevron, a former owner and operator of this site, is conducting a Portland Harbor Source Control Evaluation to assess potential impacts to the Willamette River. Stormwater discharges appear to be the only pathway of concern at the site. A program of stormwater monitoring and catch basin cleanout has been established. A complete delineation of the stormwater system still needs to be completed. DEQ anticipates that a source control decision will be completed by Summer 2008. 5/13/10 MTPugh Based on a review of the Source Control Evaluation prepared by Chevron, and as documented in DEQ's Source control Decision memo, DEQ concludes that the site media have been adequately characterized to assess the potential for site-related impacts to the Willamette River. A series of BMPs have been implemented that DEQ has determined are commensurate with contaminant levels detected in site media, and nature of the sources at the site. Per DEQ’s responsibilities as described in the Portland Harbor JSCS, DEQ proposes no additional stormwater evaluation or source control measures. This decision is contingent upon the site operator, PPC, maintaining BMPs identified in the SWPCP. DEQ may need to reconsider this decision in the event the ongoing Portland Harbor Superfund RI/FS work indicates that the level of source control at this site is not adequate to meet Remedial Action Objectives for the Willamette River. DEQ held a public comment period during the month of June 2010.
