STATE OF GEORGIA PART II DEPARTMENT OF NATURAL RESOURCES ENVIRONMENTAL PROTECTION DIVISION Page 13 of 21 Permit No.GA 0004120 A. MANAGEMENT REQUIREMENTS

1. Change in Discharge All discharges authorized herein shall be consistent with the terms and conditions of this permit. The discharge of any pollutant identified in this permit more frequently than or at a level in excess of that authorized shall constitute a violation of the permit. Any anticipated facility expansions, production increases, or process modifications which will result in new, different, or increased discharges or pollutants must be reported by submission of a new NPDES application or, if such changes will not violate the effluent limitations specified in this permit, by notice to the EPD of such changes. Following such notice, the permit may

\

be modified to specify and limit any pollutants not previously limited.

2. Noncompliance Notification If, for any reason, the permittee does not comply with or will be unable to comply with any daily maximum effluent limitation specified in this permit, the permittee shall provide the Water Protection Branch of EPD with the following information, in writing, within five (5) days of becoming aware of such condition a.

A description of the discharge and cause of noncompliance; and

b. The period of noncompliance, including exact dates and times; or, if not corrected, the anticipated time the noncompliance is expected to continue, and steps being taken to reduce, eliminate and prevent recurrence of the noncomplying discharge.

3. Facilities Operation The permittee shall at all times maintain in good working order and operate as efficiently as possible all treatment or control facilities or systems installed or used by the permittee tc achieve compliance with the terms and conditions of this permit.

4. Adverse Impact The permittee shall take all reasonable steps to minimize any i adverse impact to navigable waters resulting from noncompliance with any ef fluent limitations specified in this permit, including i such accelerated or additional monitoring as necessary to determine the nature and impact of the noncomplying discharge.

, Permit No. GA 0004120 C. BI0 MONITORING AND T0XICITY REDUCTION REQUIREMENTS The permittee may not discharge toxic wastes in concent rations or combinations which are harmful to humans, fish or aquatic life. The permittee shall not discharge an effluent which will kill 107. or more of the exposed test organisms in 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> or less, when the test solution contains volumes of effluent and dilution water proportional to the plant design flow and the 7Q10 flow of the receiving stream.

1. If toxicity is suspected in the permittee's effluent, the Division may require the permittee to develop a screening program for whole effluent biomonitoring. The schedule will be as follows for this screening approach

a. Within 90 days of Division notification, a study plan detailing the test methodology and test organisms shall be submitted for conducting forty-eight hour acute static renewal tests of the final effluent. If residual chlorine is present in the final effluent from treatment and/or disinfection processes, a prechlorinated or dechlorinated sample will also be tested.

b. Within 90 days of Division approval of the study plan, the permittee shall conduct and submit the results of the forty-eight hour static renewal tests.

2. If toxicity is found in the permittee's effluent based upon the results of the screening process, the permittee shall, within 90 '..

days of written notification by the Division, submit a Toxicity Reduction Evaluation (TRE) plan to the Division. (Note: Toxicity is defined to be a situation in which the effluent quality is such that 107. or more of the test organisms are killed within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br />, in a test solution which contains volumes of effluent and dilution water proportional to the plant design flow and the 7Q10 flow of the receiving stream.) The TRE plan shall detail the action the permittee will implement to eliminate toxicity.

Within 270 days of Division approval of the TRE plan, the permittee shall complete implementation of the TRE plan and conduct follow-up biomonitoring of the effluent in accordance with the approved TRE plan. If toxicity is still indicated, the permittee shall continue the TRE plan. The TRE plan shall not be complete until the permittee has eliminated the toxicity in its effluent. On a case specific basis, chronic toxicity testing procedures may l

be required to verify that the toxicity has been eliminated.

3. If toxicity is not indicated initially, or if there are substantial changes in the effluent composition, the permittee may be required to repeat the forty-eight hour static renewal test upon notification by the Division. On a case specific basis, chronic toxicity testing procedures may also be required. Biomonitoring of the effluent will be required at a minimum of once every three years unless otherwise noted.

1 l

l Upon approval by the Division, all study plans and TRE plans will become part of the requirements of this permit.
