What is the issue?
In August 2015, DEQ and its partner agencies began investigating odors in the Portland North Harbor area in response to numerous complaints from residents of Jantzen Beach. Based on these investigations, DEQ identified two used oil recyclers, American Petroleum Environmental Services and Oil Re-Refining Company, as sources of the odors.
The companies collect used oil, remove impurities through the re-refining process, and recycle it into reusable oil products. The oil re-refining process emits air pollutants that companies are required by law to monitor and control.
DEQ and EPA investigations in 2015 and 2016 showed that pollution levels in Portland North Harbor do not pose an imminent health risk and are generally consistent with pollution levels in other urban environments.
DEQ conducts ongoing investigations to determine if APES and ORRCO are complying with their environmental quality permits.
Between July 25, 2017, and Oct. 12, 2017, DEQ received 11
complaints identifying EcoLube Recovery, doing business as American Petroleum
Environmental Services, and Oil Re-Refining Company as sources of odors and
emissions in North Portland. DEQ used this information, along with
meteorological data from nearby weather stations, to confirm that APES and ORRCO
are possible sources of odors and emissions.
DEQ sent complaint information to both companies and requested they provide
information about their operations during the times reported in the complaints
and three-hours prior to those times. DEQ evaluated the operational data and
determined that both companies were in compliance with the requirements of their
air quality permits. DEQ also confirmed that the thermal oxidizer at APES, which
the company installed to reduce emissions and odors, was in use during all
operating hours. The thermal oxidizer controls the majority of odors and emissions from the facility; however, it is not a practical means of controlling every odor and emission.
DEQ is in the process of communicating with both companies about ways they
can further reduce odors and emissions. Any additional action by the companies
would be above and beyond what current environmental law requires.
DEQ asks that community members continue to file pollution
when they detect odors and emissions. Complaints filed through
DEQ’s complaint system are permanent records of pollution occurrences and are
DEQ’s primary means of ensuring the agency collects the necessary information to
conduct timely and thorough investigations into community concerns about
Emissions Testing at APES
In September 2017, DEQ
reviewed and approved APES’
to complete its required emissions “stack test” to determine whether
the facility’s thermal oxidizer, which it installed to reduce emissions and
odors, was operating properly, and to gather information on the facility’s
emissions of volatile organic compounds, nitrogen oxides, carbon monoxide and
On Oct. 5, 2017, a third-party contractor completed the required testing.
DEQ received the results of the test on Nov. 20, 2017, and is currently
conducting a review to validate the results. DEQ anticipates completing this
review in the first quarter of 2018, and will post its analysis on this webpage
at that time.
Preliminary results indicate that the thermal oxidizer is functioning
properly and is an effective means of controlling emissions of volatile organic
compounds. DEQ is using the stack test emissions data to determine if the
company is in full compliance with its air quality permit.
Solid Waste Violation Warning
On Dec. 13, 2017, DEQ issued a warning letter
EcoLube Recovery, doing business as American Petroleum Environmental Services,
that identified a solid waste permit violation for receiving used oil that
contained detectable amounts of polychlorinated biphenyls, or PCBs, at its North
Portland facility. APES is to correct the violation by working closely with EPA
to make sure the oil is removed from the site and properly transported and
DEQ issues Air Quality and Solid Waste permits
On Sept 20, 2017, DEQ received notification from EcoLube Recovery, LLC, a subsidiary of Clear Lube Re Refining Co., that it had acquired and taken ownership of the American Petroleum Environmental Services Inc. oil re-refining facility.
On Sept 27, 2017 DEQ issued a modified and renewed air contaminant discharge permit and a new solid waste permit to EcoLube Recovery LLC dba American Petroleum Environmental Services, Inc. DEQ considered comments received during the public comment period and made adjustments to the permits based on regulatory authority. See the two issued permits and supporting documents below.

Public hearing for APES permits
DEQ is holding a public hearing and beginning the comment period for American Petroleum Environmental Services, Inc. proposed renewed and modified air quality permit and a proposed solid waste transfer permit.
See the proposed renewed and modified air quality permit below:
See the proposed solid transfer permit below:
DEQ is holding an information meeting for a complex air quality permit modification application and a solid waste transfer permit application for Oil Re-Refining Company.
DEQ and EPA required APES to submit records on its plans for the disposal of the contents of Tank 12.
DEQ has approved the removal of the Kiln and Evaporator at ORRCO and the transition of the facility’s oil process from batch to continuous flow. Both the Kiln and Evaporator units were known sources of emissions and odors at the ORRCO facility.
DEQ worked with EPA to post infrared
videos taken during an on-site inspection of APES and ORRCO in September
of 2015. These videos helped DEQ and EPA identify APES and ORRCO as
contributors to odors and emissions.
Infrared videos of APES and ORRCO
FLIR is a company that sells infrared imaging technology used by industry and regulators to visually observe the release of specific pollutants. During an off-site inspection of APES and ORRCO on Sept. 24, 2015, DEQ and EPA used a FLIR GF320 to help pinpoint sources of odors and emissions from the two facilities. Below are videos collected during the offsite inspections with DEQ and EPA’s explanation of what the videos show: APES – Video #1
This video shows the exhaust stack of the “Back Plant Burner” at APES. The majority of what is shown exiting the stack in the video consists of hot exhaust gasses, primarily carbon dioxide and water. In this infrared video, the exhaust plume appears to quickly dissipate as the hot exhaust gasses cool. As the plume moves away from the stack, the video shows a faint residual plume indicating that some unburned Volatile Organic Compounds are likely present in the burner exhaust.
As required by the Mutual Agreement and Final Order, APES will install a thermal oxidizer to control emissions from the “Back Plant Burner” no later than June 25, 2017. APES – Video #2
This video shows emissions from the condenser stack attached to “Cook Tank 4” at APES. Emissions from all four cook tanks are routed to a unit that condenses the vapors and reduces volatile organic compound emissions. This process is also known as the “Front Plant.” DEQ and EPA are confident that the plume of gasses visible in the infrared video are primarily Volatile Organic Compounds.
As required by the Mutual Agreement and Final Order, APES will be decommissioning the four of the cook tanks by no later than May 26, 2017. ORRCO – Video #1
This video shows the exhaust stack of “Burner #9” at ORRCO. The majority of what is shown exiting the stack in the video consists of hot exhaust gasses, primarily carbon dioxide and water. In the infrared video, the exhaust plume appears to quickly dissipate as the hot exhaust gasses cool. As the plume moves away from the stack, the video shows a faint residual plume indicating that some unburned Volatile Organic Compounds are likely present in the burner exhaust. ORRCO – Video #2
This video shows emissions from the “Thumper Tank” at ORRCO. The stack vents gasses that have passed through a condensing unit at the facility. DEQ and EPA are confident that the emissions visible in the infrared video are primarily Volatile Organic Compounds.
While the video footage shows emissions that are otherwise invisible to the naked eye and helps identify potential sources of emissions, the infrared technology does not quantify the amount of emissions. DEQ has required APES to conduct stack testing as part of a Mutual Agreement and Final Order (MAO) with specified timeframes for installation of additional control equipment. Stack testing allows DEQ to determine the amount of actual emissions from processes and will verify that control technology is effectively controlling emissions. Modified and renewed air quality permits for both facilities will include additional language that requires emission controls to be operated and maintained following equipment manufacturer specifications to ensure emissions reductions are maintained into the future.Visit our YouTube channel.
DEQ is holding an information meeting for a complex air quality permit modification application and a solid waste transfer station permit application for American Petroleum Environmental Services. See the notice below for more information:
EPA recently communicated with APES about the company's plans to remove the contents of Tank 12. See the letter below for more information.
The following documents provide information regarding correspondence and reporting for American Petroleum Environmental Services and Oil Re-Refining Company that DEQ has received or originated May through August 2016, as well as a Fact Sheet updated February 6, 2017.
On Dec. 27, 2016, DEQ entered into a Mutual Agreement and Final Order with APES that requires for the installation of control technology at the facility. A compliance schedule for the implementation of the additional controls is documented in the MAO.

The following documents provide information regarding correspondence and reporting for American Petroleum Environmental Services and Oil Re-Refining Company that DEQ has received or originated through November 2016.
Information about planned shutdown at APES, Sept. 27, 2016
DEQ has determined that the air pollution control technology that American Petroleum Environmental Services proposes to install will appropriately control gaseous emissions from facility operations.
In a Sept. 3 letter
sent to DEQ, Oil Re-refining Company proposed improvements and modifications to the facility to reduce air emissions and nuisance odors.
On Aug. 23, APES provided information DEQ required so DEQ can complete a technology analysis to ensure that the facility has appropriate controls for controlling gaseous emissions.
Since late August 2015, DEQ has been investigating odors in response to numerous complaints in the Jantzen Beach area on Hayden Island. Based on these investigations, some of which were in partnership with EPA, DEQ identified American Petroleum Environmental Services as one source of odors and continues to investigate other possible sources including Oil Re-refining Company. Both facilities recycle oil.
DEQ encourages people to continue documenting and filing odor complaints through the DEQ Complaints Hotline or online complaint form. DEQ will compare complaint information to meteorological data and facility operation information to determine if there are other sources of odors in the area.
DEQ may or may not be able to pinpoint other odor sources. Also, a business may be in compliance with its air quality permit but still may emit odors. In that case, DEQ uses the nuisance odor strategy which outlines DEQ’s process for addressing potential nuisance odor sources.
Air quality monitoring
EPA assisted DEQ in the odors and air emissions investigation by conducting limited short term air testing in the area from September 2015 through January 2016. The results are included in the following report:
DEQ conducted additional sampling and monitoring on Jantzen Beach and near APES and ORRCO to identify the pollutants, conditions and sources contributing to the odors and emissions.
