Work is ongoing at the Portland Harbor\/Willamette River River Mile 11 East (RM11E) area, under the direction of EPA Region 10, to support remedy selection and implementation in the area. Remedial action will be based on the january<\/g> 2017 ROD issued for Portland Harbor by EPA. The RM11E area is an important area within the Harbor, being<\/g> located at the most upstream end of the study area and containing high concentrations of contaminants, notably PCBs. It has been identified as an “early action” area by EPA. Important investigation work elements completed in the past few years under EPA have included: a) upland groundwater and riverbank investigation efforts; b) sediment investigation; c) porewater investigation; and<\/g> d) remedy implementability<\/g> analysis. In January 2018, an Administrative Steelement<\/g> Agreement and Order on Conset<\/g> for Supplemental RI\/FS Work and Remedial Design, Amendment No. 1, was complete<\/g> by EPA and the RM11E Group parties. In March 2018, a draft Basis of Design Report WP was submitted to EPA,<\/g> and included DEQ review and comment. A revised document (BODR WP) was submitted to EPA. In May 2018, a Recontamination Assessment (upland and in-water) was submitted to EPA on behalf of the RM11E Group.<\/p>\n

Site: Gasco<\/strong><\/p>\n

EPA found the site to have the highest levels of PAHs in the harbor.<\/p>\n

Gasco is a former manufactured gas plant which deposited wastes into upland tar ponds for many years. The site is located near river mile 6.5 between the St. Johns and Railroad bridges on the southwest side of the Willamette River. The tar ponds overflowed into the Willamette River for decades. The overflow remnants were visible during low river stages and were eroding. Removal of tar deposits in the river was completed in the fall of 2005. These deposits contained hazardous substances such as TPAH, benzene, and cyanide.<\/p>\n

History of the Site and Contamination
<\/strong>According to the EPA:
<\/span>Gasco purchased the site in approximately 1910. At that time, the site was larger, approximately 85 acres. Today the site is 44.65 acres. Gasco built and operated an oil gasification plant on the site between 1913 and 1956. Between 1913 and 1923, only gas and lampblack briquettes were produced. In 1923, by-products refining began. After 1925, when tar refining operations began, the quantity of tar within the waste stream would have decreased, but waste tar in the effluent continued to occur as suspended material and emulsions from the secondary tar box. Prior to 1941, all wastewater effluent and tar stills<\/g> from the gasification process and by- product<\/g> refining was discharged to a stream channel leading from the production area to the Willamette River, or to<\/g> low lying areas of the site. After 1941, wastewater effluent and tar stills were disposed of into settling ponds adjacent to the Willamette River in the central portion of the Gasco facility including what is now part of the Siltronic property. Historic photographs suggest that the tar ponds periodically overflowed to the Willamette River. When the plant was shut down in 1956, an estimated 30,000 cubic yards of tar waste had accumulated in the ponds. The southern portion of the original Gasco property was sold and is now owned by Siltronic Corporation (Siltronic). The tar ponds on the northern portion of the site were buried under 10 feet of fill in 1973. Current uses of the Gasco site, other than as a liquefied natural gas plant, are bulk<\/g> transfer of creosote oil and coal tar pitch, liquefied gas storage, and bulk petroleum storage. (Gasco Siltronic Approval Memo, p. 1-2<\/a>) <\/span>Operation of the property by Siltronic resulted in additional releases of <\/span>Trichloro-ethylene<\/g> <\/span>(TCE).<\/span><\/p>\n

Early Action<\/span><\/strong><\/span>
<\/span><\/strong>As mentioned above, early action in 2005 removed tar deposits that contained <\/span>hazardous substances such as TPAH, benzene, and cyanide.
In 2009 EPA found that “[c]ontaminants known to be present at the Gasco\/Siltronic facility that pose a substantial risk to human health or the environment include naphthalene, cyanide, benzene, tars, oil, creosote, phenols, polynuclear aromatic hydrocarbons (PAHs), BTEX, phthalates, Carbazole, chlorophenol, chrysene, cobalt, DDT, dibenzofuran, dimethylphenol, ethylbenzene, pyrenes, manganese, PCP, VOCs, (such as vinyl chloride, TCE, toluene, and others which are commingled with MGP wastes) and lead, starting in the uplands and continuing through the riverbank and into sediment in the river.” <\/span>(Gasco Siltronic Approval Memo, p. 4-5<\/a>).<\/span><\/p>\n

EPA approved the development of an EE\/CA to analyze early action cleanup in light of the greater <\/span>harborwide<\/g> RI\/FS and ROD processes.<\/span><\/p>\n

Stay tuned for updates on any cleanup activity at this site.<\/span><\/p>\n
