![]() ![]() Spill and fire scenarios in the environmental review used methodologies and computational models prescribed by the Pipeline and Hazardous Materials Safety Administration and approved on similar facilities. You can find the status of those permits by clicking on the Current Development Permit Statuses header at the top of the City’s project permit page.įederal standards require the facility to be designed and built to ensure that a spill or fire would have no offsite impacts. The facility is required to undergo environmental review and receive permits and approvals from several local, state and federal agencies. More than two dozen permits come from the City of Tacoma. PSE has been using the area to stage construction equipment. The ground surface over the petroleum impacted area is currently paved and will remain paved. All 90,000 tons of cuttings were taken to LRI Landfill in Pierce County for disposal. Environmental sampling of drill cuttings found no indication of intersection with the Occidental Chemical site plume or the Alexander Avenue Tank Facilities petroleum plume. Between January and June of 2017, 90,000 tons of soil were drilled out during the installation of the concrete columns. ![]() Soil removed from the site is tested to make sure it meets non-hazardous standards before being taken to a landfill. PSE’s plant infrastructure is intentionally located to the south of the old tank farm location to minimize the potential of encountering contaminated soil and groundwater. PSE’s lease has allowed the port to put the property back into productive use while continuing to work with Ecology to determine the final cleanup. The port is working with the Department of Ecology to evaluate alternatives and develop a site cleanup plan. Investigation results indicate the hydrocarbon groundwater plume has been decreasing in size and concentration over time. Historical operations at the former tank farms resulted in an area of contaminated soil and groundwater impacted by benzene, gasoline-range total petroleum hydrocarbons (TPH) and diesel-range TPH. Petroleum storage and distribution facilities (tank farms) operated along the northern portion of the 901 Alexander Ave. ![]() Petroleum pollution is located within the footprint of PSE’s leased area along the north limit of the property boundary. While the facility will be close to the contaminated former Occidental Chemical site, PSE is not building over the solvent contamination plume, as verified by the state Department of Ecology. to replace 10 heavy-duty trucks with LNG-fueled trucks for local hauling.
