(a) Any person who owns or operates a facility of any type or who desires to erect, modify, alter, or commence operation of a facility of any type which results or will result in the discharge of pollutants from a point source into the waters of the state shall obtain from the director a permit to make such discharge. Any person desiring to erect, modify, alter, or commence operation of a facility which will result in such discharge but which is not discharging such pollutants as of July 1, 1974, must obtain such permit prior to the discharge of same. Any person who is operating a facility which results in such discharge as of July 1, 1974, may continue to make such discharge pending final action by the director on the application for such discharge permit, provided that such application has been filed with the director by September 29, 1974; and provided, further, that such discharge does not present an immediate health hazard to the public. The director, under the conditions he prescribes, may require the submission of such plans, specifications, and other information as he deems relevant in connection with the issuance of such permits. The director may, after public notice and opportunity for public hearing, issue a permit which authorizes the person to make such discharge, upon condition that such discharge meets or will meet, pursuant to any schedule of compliance included in such permit, all water quality standards, effluent limitations, and all other requirements established pursuant to this article.

(b) Any person desiring to erect or modify facilities or commence or alter an operation of any type which will result in the discharge of pollutants from a nonpoint source into the waters of the state, which will render or is likely to render such waters harmful to the public health, safety, or welfare, or harmful or substantially less useful for domestic, municipal, industrial, agricultural, recreational, or other lawful uses, or for animals, birds, or aquatic life, shall obtain a permit from the director to make such discharge. Any person desiring to erect, modify, alter, or commence operation of a facility which will result in such discharge but which is not discharging such pollutants as of July 1, 1974, must obtain such permit prior to the discharge of same. The director, under the conditions he prescribes, may require the submission of such plans, specifications, and other information as he deems relevant in connection with the issuance of such permits. The director may, after public notice and opportunity for public hearing, issue a permit which authorizes the person to make such discharge upon condition that such discharge meets or will meet, pursuant to any schedule of compliance included in such permit, all water quality standards, effluent limitations, and all other requirements established pursuant to this article.

(c) The director is authorized to require as conditions in permits issued under subsections (a) and (b) of this Code section the achievement of effluent limitations established pursuant to this article. In imposing effluent limitations as conditions in such permits, the director shall base his determination upon the assessment of technology and processes unrelated to the quality of the receiving waters of this state. Effluent limitations required as conditions of such permits shall be achieved in the shortest reasonable period of time consistent with state law and the Federal Water Pollution Control Act, as amended. The director is further authorized to set schedules of compliance and include such schedules within the terms and conditions of such permits for the discharge of such pollutants into the waters of the state and to prescribe terms and conditions for such permits to assure compliance with applicable effluent limitations and water quality criteria established pursuant to this article, including, but not limited to, requirements concerning recording, reporting, monitoring, entry, and inspection to the extent permissible under this article, and such other requirements as are consistent with the purposes of this article.

(d) Each permit issued under subsections (a) and (b) of this Code section shall have a fixed term set by the director consistent with the federal Clean Water Act of 1977, P.L. 95-217, as now or hereafter amended but not to exceed ten years. Upon expiration of such permit, a new permit may be issued by the director after review by him in accordance with such guidelines as he shall prescribe; after notice and opportunity for public hearing; and upon condition that the discharge meets or will meet, pursuant to any schedule of compliance included in such permit, all applicable water quality standards, effluent limitations, and all other requirements established pursuant to this article. The director is authorized to include in permits issued under this subsection such terms and conditions as are authorized under subsections (a) and (c) of this Code section. The director may revoke, suspend, or modify any permit issued under this subsection or subsection (a) or (b) of this Code section, for cause, including but not limited to the following:

(1) Violation of any condition of the permit;

(2) Obtaining a permit by misrepresentation or failure to disclose fully all relevant facts;

(3) Change in any condition that requires either a temporary or permanent reduction or elimination of the permitted discharge.

In the event of modification, suspension, or revocation of a permit, the director shall serve written notice of such action on the permit holder and shall set forth in such notice the reason for such action.

(e) Notwithstanding any other provision in this Code section, the director may issue permits, after notice and opportunity for public hearings, for the discharge of dredged or fill material into the waters and wetlands of the state, in accordance with the standards and criteria set forth in Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. Section 1344, as amended by the Clean Water Act of 1977 (P.L. 95-217), upon receiving delegation of such authority, except that this subsection shall not authorize the director to issue permits with respect to projects under review by the United States Army Corps of Engineers as to which a public hearing has been held before July 1, 1974. In administering such a program, the director is empowered with the authority to take such action as is set forth in Section 404(h)(1)(A) through (H) of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. Section 1344, as amended by the Clean Water Act of 1977 (P.L. 95-217). No person covered by this subsection shall discharge dredged or fill material into the waters and wetlands of this state except in a manner which complies with this article and Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. Section 1344, as amended by the Clean Water Act of 1977 (P.L. 95-217). (f) The director may issue general permits for discharges of pollutants from categories of point sources which are subject to the same permit limitations and conditions. Such general permits may be issued without individual applications. At the discretion of the director, numeric effluent limitations and effluent monitoring provisions may be included in general permits or best management practices may be substituted for numeric effluent limitations without a showing that it would be infeasible to include effluent limitations; provided, however, that the director shall incorporate the provisions related thereto as provided in paragraphs (1), (2), and (3) of subsection (a) of Code Section 12-7-6 into any general permit issued for the discharge of storm water from construction activity.
