Description:

The U.S. Environmental Protection Agency (USEPA) is conducting what it refers to as a detailed study of the petroleum refinery effluent limitations guidelines (ELG) to determine if revisions are appropriate. In fall 2015 USEPA stated that it would issue an ICR (Information Collection Request) in 2016. USEPA has not achieved this target but continues to work on its detailed study of the industry. The paper will present an update of the current information from USEPA relative to the ICR and other evaluations that the Agency is currently conducting using discharge monitoring report (DMR) data in its Integrated Compliance Information System (ICIS). USEPA may also evaluate whether or not the existing best practicable control technologies (BPT) for conventional and non-conventional pollutants should be revised based on demonstrated treatment performance by petroleum refineries. The potential effects of more restrictive BPT ELGs will also be discussed. The paper will also evaluate the impact of possible new numeric discharge limitations for specific constituents, including selenium and mercury. Any new numeric discharge limitations will be technology based and promulgated as best available technology (BAT). Revised ELGs for the Steam Electric Power Industry (40 CFR 423) were promulgated on November 3, 2015 and require extremely low concentration-based limits for these two metals which USEPA could consider transferrable to the petroleum refinery ELGs. The paper will present an overview of the transfer of this technology for treatment of refinery wastewaters. Technical challenges and costs will be also discussed. The paper will also present some considerations relative to wastewater characterization for ICR submittal. Considerations for sampling and analytical methods will be included to assure that any data provided to USEPA in an ICR response are representative of the waste streams for which it is submitted.
