(a) Notwithstanding the provisions of Code Section 12-5-23 or any rule, regulation, or order adopted or issued pursuant to this article, no person who has been issued a National Pollutant Discharge Elimination System permit which allows the discharge of 1,000,000 gallons or more per day from a water pollution control plant operated by such person which discharges waste water into the Chattahoochee River between Buford Dam and West Point Reservoir shall discharge waste water from such person's water pollution control plants which contains more than 0.75 milligrams of phosphorus per liter of waste water on a monthly average basis or which fails to comply with any stricter standard adopted pursuant to Code Section 12-5-23.

(b) Notwithstanding the provisions of subsection (a) of this Code section, any person who has been issued a National Pollutant Discharge Elimination System permit and who has entered into a finalized consent order shall conform to the schedule adopted in such order as such order appeared on April 25, 1996. Except as provided in subsection (c) of this Code section, compliance with the discharge limitation provided by this Code section shall not be extended beyond July 4, 1996, and the order shall require that person to make his or her best efforts to achieve compliance with the discharge limitation by December 31, 1993.

(c)(1) Notwithstanding the provisions of subsection (b) of this Code section, any person who entered into a consent order as provided in subsection (b) of this Code section but fails to complete the required phosphorus reduction improvements by July 4, 1996, shall not later than such date submit to the division a schedule stipulating annual construction milestones for the completion of all improvements required to achieve a discharge level of 0.64 milligrams of phosphorus per liter of water at each of such person's individual waste-water plants by not later than January 1, 2001; provided, however, that such person shall not discharge waste water from such person's water pollution control plants after February 1, 1997, which exceeds 0.64 milligrams of phosphorus per liter of water.

(2) If the director approves the schedule submitted pursuant to paragraph (1) of this subsection, such person shall be bound by that schedule. If the director does not approve said schedule by August 1, 1996, the director shall not later than September 1, 1996, establish an alternative schedule with a final completion date not later than January 1, 2001, and such person shall be bound by the alternative schedule.

(3) Any monetary penalties stipulated in any consent order regarding phosphorus effluent limitations executed by the director and another person prior to April 25, 1996, shall be the only monetary penalties required to be paid by such person as long as such person is in compliance with the construction milestones in the schedule approved or established by the director in paragraph (2) of this subsection; provided, however, that if such order is declared invalid by the courts, then the penalties for noncompliance with subsection (a) or (b) of this Code section shall be as provided for in Code Sections 12-5-51 through 12-5-53.

(4) If such person fails to meet a construction milestone, he or she shall pay a penalty in the amount of $25,000.00 per day until that construction milestone is met. If a particular construction milestone is not met for six months after the date specified, the penalty shall be increased to $100,000.00 per day until that construction milestone has been met. Failure to meet a construction milestone shall not affect the date of any succeeding construction milestones.

(5) If the person fails to complete all required construction by January 1, 2001, he or she shall pay a civil penalty in the amount of $100,000.00 per day until construction is completed. After construction is completed, the suspension of the liabilities and penalties provided for in Code Sections 12-5-51 through 12-5-53 for noncompliance with the provisions of subsection (a) of this Code section shall be ended.

(6) If in any month after July 1, 1996, and before December 31, 1998, a person discharges waste water from such person's water pollution control plants containing more than 0.75 milligrams of phosphorous per liter of water on a monthly average basis; or if in any month after January 1, 1999, and before December 31, 2000, a person discharges waste water from such person's water pollution control plants containing more than 0.64 milligrams of phosphorous per liter of water on a monthly average basis; or if in any month after January 1, 2001, a person discharges waste water from any individual water pollution control plant containing more than 0.64 milligrams of phosphorous per liter of water on a monthly average basis, such person shall not permit any additional sewer connections within such person's corporate limits until he or she has been in compliance with such provisions for three consecutive months. The provisions of this subsection shall apply without regard to the provisions of paragraphs (1) through (5) of this subsection and shall not be suspended or terminated; provided, however, that nothing in this paragraph shall prohibit additional sewer connections required for any project constructed by or in partnership with a public housing authority, as long as the additional connections for such project do not cause the total quantity of sewage generated to exceed the total quantity of sewage generated by that public housing authority's housing units in existence on January 1, 1995.
