EPA is hosting a webcast to provide additional information on the supplemental notice of proposed rulemaking for the CAFO NPDES program that was published in the Federal Register on March 7, 2008 (www.epa.gov/npdes/afo/revisedrule). Participants will be able to submit questions about the supplemental proposal to the EPA presenters during the webcast to gain a better understanding of this rulemaking effort. This webcast is intended to support the public comment period for this proposed rule, which closes on April 7, 2008.
