  • The Sixth Circuit U.S. Court of Appeals Decisions
    • The Sixth Circuit Court Decision on March 28, 2011 (Extension of Stay)
      On March 28, 2011, the United States Court of Appeals, Sixth Circuit, granted a motion to extend the stay currently in place in the matter of National Cotton Council of America v. U.S. EPA,553 F.3d 927 (2009). The stay of the Court's 2009 decision is now effective until October 31, 2011. As a result of this extension, the federal regulation exempting pesticide discharges in compliance with FIFRA from the requirement to apply for an NPDES permit continues in effect through October 31. Until that time, persons applying pesticides have no affirmative duty to apply for an NPDES permit, in accordance with federal law.

      Those who have previously applied for coverage under the three pesticide discharge permits adopted by the State Water Board on March 1, 2011 and the Weed Control Permit (Water Quality Order No. 2004-0009-DWQ), must submit a notice of termination if they do not intend to comply with the applicable permit. Once the stay expires, a new application for coverage will be required.
