American Petroleum Institute comments on EPA's Technical Support Materials for Aquatic Life Ambient Water Quality Criterion for Selenium - Freshwater 2016, Docket ID No. EPA-HQ-OW-2016-0551.
American Petroleum Institute request for 60-day extension of the comment period for United States Environmental Protection Agency Draft Technical Support Materials for the Aquatic Life Criterion for Selenium - Freshwater 2016: 1) Technical Support for Adopting and Implementing EPA's 2016 Selenium Criterion in Water Quality Standards; 2) Technical Support for Fish Tissue Monitoring for Implementation of EPA's 2016 Selenium Criterion; 3) Frequently Asked Questions (FAQs): Implementing the 2016 Selenium Criterion in Clean Water Act Sections 303(d) and 305(b) Assessment, Listing, and Total Maximum Daily Load (TMDL) Programs; and 4) Frequently Asked Questions (FAQs): Implementing WQS that Include Elements Similar or Identical to EPA's 2016 Selenium Criterion in Clean Water Act Section 402 NPDES Programs.
EPA published the final selenium criterion on July 13, 2016. In the final criterion EPA recommended that states and authorized tribes adopt into WQS one selenium criterion composed of four elements: two fish tissue elements (i.e., egg-ovary and whole-body and/or muscle) and two water column elements (i.e., 30-day average and intermittent exposure). Because this is the first fish tissue-based aquatic life criterion, EPA has developed documents to assist in the implementation of this criterion. The technical support materials cover water quality standards adoption, NPDES permitting, waterbody assessment and 303(d) listing, and fish tissue monitoring.
