Update Sept. 7, 2016
In a Sept. 3 letter sent to DEQ, ORRCO proposed to install new air pollution control equipment and modify existing equipment. The modifications proposed by ORRCO should significantly reduce odors and gaseous emissions from operations. The letter also states ORRCO will submit a modified air quality permit renewal application.
Oil Re-refining Company, located at 4150 N Suttle Road in Portland, is an oil re-refinery also known as a used oil processing facility. ORRCO heats used oil to remove water and light ends and then sells the used oil as a product. Lights ends are the more volatile products of petroleum refining, such as butane, propane and ethane.
ORRCO also accepts wastewater for treatment. The company operates under a DEQ Standard Air Contaminate Discharge permit, a DEQ stormwater permit, and a City of Portland wastewater pretreatment permit.
ORRCO is registered with DEQ as a hazardous waste transporter, used oil collection center, used oil transporter and used oil processor/re-refiner. ORRCO is also working with DEQ’s Cleanup Program to address historical contamination on the site.
Residents nearby at Jantzen Beach have filed numerous complaints about odors since August 2015. DEQ is investigating ORCCO as a possible source of these odors.
DEQ and EPA have been working with the company to identify technical pollution control options related to the facility’s air emissions that cause odors. As part of this process, DEQ and EPA require ORCCO to submit a series of records and testing analysis results to DEQ and EPA on the sixth and 21st of every month. The agencies use this information to determine whether ORCCO is continuously in compliance.
Following are links to two EPA and DEQ joint Clean Air Act Section 114 letters that specify records and testing analysis results APES must provide:
Air quality permit
ORRCO’s air quality permit expired on March 1, 2013. ORCCO submitted a timely renewal application allowing DEQ to administratively extend its permit until DEQ renews the permit.
DEQ is in the process of determining if ORCCO has the correct pollution control equipment to minimize odors and emissions. If additional air pollution control equipment is required, DEQ will incorporate those requirements into the permit renewal. Once the proposed permit changes are incorporated into a draft renewal permit, DEQ will issue a public notice seeking public comment and announcing a hearing, at a convenient time and location, offering people a chance to comment on the draft permit in person.
Hazardous waste regulations
A variety of used oil management practices are exempt from federal hazardous waste regulations. Oregon has specific used oil regulations that are slightly stricter than the federal regulations. DEQ has been working with ORRCO to verify which of its practices are exempt from hazardous waste regulations and which ones require further regulation. Any of the practices that are exempt from hazardous waste regulations may still require a DEQ solid waste disposal permit.
In April 2016 DEQ requested that ORRCO stop using the onsite kiln, which ORRCO previously used to burn solids contaminated with used oil. In July 2016, DEQ also requested that ORRCO stop evaporating wastewater.
Solid waste regulations
ORRCO submitted a permit application for the solid waste activities conducted onsite. DEQ will continue to develop a solid waste treatment and/or transfer station permit for this facility.
In April 2016, DEQ requested that ORRCO stop using the onsite kiln, which ORRCO previously used to burn solids contaminated with used oil. In July 2016, DEQ also requested that ORRCO stop evaporating wastewater.
