city, TCEQ and the EPA shall have the right to set up on the user's property such devices as are necessary to conduct sampling, inspection, compliance monitoring and/or metering operations. If a user has in force security measures requiring proper identification and clearance prior to entry into their premises, the user shall make any necessary arrangements with their security service(s) so that personnel from the city presenting suitable identification (or such personnel from state or federal agencies) will be allowed to enter, without delay, for the purposes of performing their specific responsibilities. In no case shall there be a delay greater than ten (10) minutes for access to control points or control manholes and thirty (30) minutes for access to records or facility inspection. Sampling shall be done on a twenty-four (24) hour composite, flow -weighted basis when possible. No part of this article shall be interpreted to prevent non -flow -weighted composite or grab sampling whenever necessary or required to monitor or check any user for compliance with this article. All sampling and analysis shall be in accordance with the methods described in 40 CFR Part 136. If the supervisor, other city authorized personnel, EPA or TCEQ personnel are denied access to the facility, or any part thereof, in performance of required duties to insure compliance with this ordinance, or to protect the overall public health, safety or welfare of the community or the environment, may seek issuance of a search warrant from an appropriate court of law to gain such access. Sec. 34-73. - Sample analysis. (a) Wastewater and waste samples will be collected and tests performed by city personnel at the city's discretion. The laboratory procedures to be used in the examination of industrial or other wastes or wastewater will be those set forth in 40 CFR 136. All significant industrial users shall be sampled at least once every six (6) months by the user. All significant industrial users will be sampled a minimum of once per year by the city for compliance with discharge limitations listed in Sec. 34-106 of this article. Sampling may be required at a greater frequency if a violation is found. Users subject to categorical pretreatment standards shall be sampled a minimum of once a month for substances limited in appropriate standards until a one (1) year history of compliant sampling is established. They shall thereafter be sampled twice annually unless a violation is found. When a violation is found, sampling shall be of a frequency to identify the magnitude of the violation and continued at the discretion of the city until compliance is achieved and the city is satisfied that the reason for the problem has been corrected. Sampling may be done by the user, city or contract personnel at the discretion of the city. All regular sampling and analysis costs set forth above shall be paid by the user. If sampling performed by the user indicates a violation, the user shall notify the city within twenty- four (24) hours of becoming aware of the violation. The user shall then resample and report the sampling and analysis and submit the results to the city within thirty (30) days of becoming aware of the violation. The user is not required to resample if: Page 16 of 45
