Sec. 8.
The following conditions apply to all NPDES permits and shall be incorporated into the permits either expressly or by reference:
A permittee may claim an affirmative defense to a permit violation if the circumstances of the noncompliance meet the criteria of an upset as defined in subdivision (13).
This subdivision does not act as an independent source of authority to set effluent limitations. Such limitations will be based on the design removal rates of installed treatment facilities only as required under this article. Nor should this subdivision be construed to require the operation of installed treatment facilities that are unessential for achieving compliance with the terms and conditions of the permit.
A written submission shall also be provided within five (5) days of the time the permittee becomes aware of the circumstances. The written submission shall contain a description of the noncompliance and its cause; the period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent recurrence of the noncompliance. The commissioner may waive the written report on a case-by-case basis if the oral report has been received within twenty-four (24) hours.
