RESPONSE TO COMMENTS L

DRAFT NPDES PERMIT Permit No.: LA004?/31 Permittee : Gulf States Utilities Company Facility Name/ Location: River Bend Station Draft Permit Public Notice Date: August 20, 1988 Prepared by: Kenneth Holley Issue No. 1 ,

The Louisiana Department of Environmental Quality, as a conditon of certi-  !

fication, requested that fecal coliform and chlorine limitations be included  !

at sanitary Outf alls 004 and 005.

Response No. 1 The proposed permit was in response to GSU's May 25, 1988, modification ,

- request, which asked that a metal cleaning outfall be added to the permit.

GSU's request was included in the proposed permit as Outf all 102. The Louisiana Department of Environmental Quality did not have any comments on Outfall 102. ,

When a permit is modified, only the conditions subject to modification are >

reopened (40 CFR 122.62). The conditions for Outf all 004 and 005 were not reopened in the proposal. Therefore, the Agency cannot grant LDEQ's request at this time, in addition, it was noted that the pages appended to the LDEQ letter contained fecal coliform reporting requirements and not fecal coliform limitations per se.

9. Severability s

The provisions of this pemit are severable, and if any provision of this permit or the application of any provision of this permit to any ,

circumstance is held invalid, the application of such provision to other circumstances, and the remainder of this permit, shall not be affected thereby.

10. Definitions .

-The following definitions shall apply unless otherwise specified in this permit:

a. " Daily Discharge" means the discharge of a pollutant measured ,

during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the " daily discharge" is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants with limitations expressed in other units of measurement, the " daily discharge" is calculated as the average measurement of the pollutant over the sampling day. " Daily discharge" determination of concentration made using a composite sample shall be the concentration of the composite sample. When grab samples are used, the " daily discharge" determination of concentration shall be the arithmetic average (weighted by flow value) of all samples collected during that sampling day,

b. " Daily Average" (also known as monthly average) discharge limitation means the highest allowable average of " daily discharges" overL a calendar month, calculated as the sum of all " daily discharges" measured during a calendar month divided by the number of " daily discharges" measured during that month. When the permit establishes daily average concentration effluent limitations or conditions, the daily average concentration means the arithmetic average (weighted by flow) of all " daily discharges" of concentration determined during the calendar month,

c. ")aily Maximum" discharge-limitation means the highest allowable "siaily discharge" during the calendar month.

d. The tem "MGD" shall mean million gallons per day.

e. The term "mg/l" shall mean milligrams per liter or parts per million (ppm).

f. The term "ug/l" shall mean micrograms per liter or parts per billion (ppb).

L-SECTION B. OPERATION AND MAINTENANCE OF POLLUTION CONTRU S

1. Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment trd control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also l includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of backup or auxiliary f acilities or similar systemt which are installed by. a permittee only when the operation is necessary to achieve compliance with the conditions of the permit.

-2. Need to Halt or Reduce not a Defense It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.

3. Duty to Mitigate The permittee shall take all reasonabie steps to minimize or prevent any discharge in violation of this permit which has a reasonable likelihood of adversely affecting human health or the environment.

4. Bypass of Treatment Facilities

a. Definitions (1) " Bypass" means the intentional diversion of waste streams from any portion of a treatment facility.

(2) " Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and >

permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.

b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Part II.B.4.c and 4.d.

t j

Permit No. LA0042731 Page 5 of PART 11 l-

c. Notice (1) Anticipated bypass. If the permittee knows in advance ,

of the need for a bypass, it shall_ submit prior notice, if possible at least ten days before the date of the ,

bypass.

(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II.D.6 (24-hour notice),

d. Prohibition of bypass (1) Bypass is prohibited, and the Directer may take enforcement action against a permittee for bypass, unless:

(a) Bypass was unavoidable to prevent loss of life..

personal injury, or severe property damage; (b) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment- facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable ,

engineering judgment to prevent a bypass which occured  ;

during normal periods of equipment downtime or preventive maintenance; and, (c) The permittee submitted notices as required by l Part II.B.4.c.

(2) The Director may approve an anticipated bypass, after considering its adverse effects, if the Director determines that it will meet the three conditions listed at Part II.B.4.d.(1).

5. Upset Conditions 1

a. Definition. " Upset" means an exceptional incident in which there 1 is unintentional and temporary noncompliance with technology-based  !

permit effluent limitations because of factors beyond the reasonable l control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.
