Pemit No. TX0065854-SECTION 8. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS

1. Proper Operation and Maintenance

.The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control -(and related appurtenances) which are .

installed or. used by the pemittee to achieve compliance with the conditions of this pemit. Proper operation and maintenance includes. effective perfonnance, t adequate funding, adequate operator staffing and training, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of backup or auxiliary ,

facilities or similar systems only den 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 pemit.

3. Duty to Mitigate i

The permittee shall take all reasonable steps to rinimize 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 '

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

(2) " Severe property damsge" means substantial physical _ damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and peaanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic kss 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 paragraphs c and d of.this section.

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.

-i (2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in section D, paragraph 6  ;

(24-hour notice).- -

d. Prohibition of bypass. ,

(1) Bypas:: is prohibited and ~the Director may take enforcement action against a permittee for bypass, unless: .

4 (a) Bypass was unavoidable to prevent loss of life, personal

. . injury, or severe property damage; I (b) There were no feasible alternatives to the bypass, such as the -

use of auxiliary treatment facilities, _ retention of untreated wastes, or maintenance during nomal periods of equipment-downtime. This condition is not satisfied if the permittee could have installed adequate backup. equipment to prevent a i bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (c) The permittee submitted notices as required under paragraph 3.c. of this section.

(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 above'in paragraph d.(1). of this section.

5. Upset Conditions

a. Definition. "

Upset" means an exceptional ircident in dich there is -

unintentional and temporary noncompliance with technology-based permit affluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operatfor.al error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

1

b. Effect of an upset. An upset constitutes-an affimative defense to an action brought for noncompliance with such technology-based permit

effluent limitations if the requirements of parsgraph c of this taction are met. No determination made during adminisc. ative review of claims e that noncompliance was caused by' upset, and before an action fce noncompliance, is final administrative action subject.to-judicia?  ;

review. '

c. Conditions necessary for a demonstration of upset. A permittee who .

i wishes to establish the affimative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

1. Representative Sampling Samples and measurements taken as required herein shall be representative of the volume and nature of the. monitored. discharge. All samples shall be taken at the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins or is diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed without notification to and the approval of the Director.

2. Flow Measurements Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be installed, calibrated and maintained.to insure that the accuracy of the measurements are consistent with the accepted capability of that type of device.

Devices selected shall be capable of measuring flows with a maximum deviation of less than + 107, from true discharge rates throughout the range of expected discharge volumes. Guidance in selection, installation, calib.ation ar.d -

operation of acceptable flow measurement devices can be obtained from the following references:
