(a) Where grease, oil and sand interceptors, pretreatment or flow equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner(s) at the owner's expense.
(b) Industries subject to federal specific categorical pretreatment standards and all other industries when required by the City Engineer shall have a sampling facility, to be installed by the user, having a suitable structure together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such structure, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Engineer. The structure shall be installed by the owner(s) at his expense and shall be maintained by him so as to be safe and accessible by authorized agents of POTW at all times.
(c) The City may inspect the monitoring facilities or perform the sampling and analysis required of any industrial user to determine compliance with the mandates of this chapter. Costs incurred by the POTW for monitoring and sampling shall be reimbursed by the industrial user.
(d) The City may require industrial users to self-monitor its flow and analyze its characteristics, to properly define the concentration of various pollutants and to ascertain compliance with the limits defined in Section 933.20. Cost for all self-monitoring efforts shall be borne by the user.
(e) Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto. Where 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the City Engineer determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the City Engineer; location and time to be determined on an individual basis subject to approval by the Engineer and other regulatory agencies.
(f) Any industry monitoring a pollutant more frequently than required by the Control Authority and according to procedures set forth in this section shall include the results of that monitoring in the reports required to be submitted to the Control Authority.
(g) Any grease, fat or floatable oils coming from a grease trap or interceptor resulting from a structure that the specific commercial entity has not performed maintenance. Specific commercial entities shall maintain a regular schedule of maintenance of their grease trap/interceptors that are subject to periodic review and inspections by the City Plumbing Inspector and/or the City Industrial Waste Inspector.
(h) If sampling performed by an industrial user indicates a violation, the user shall notify the control authority within twenty-four hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the control authority within thirty days after becoming aware of the violation. Where the control authority has performed the sampling and analysis in lieu of the industrial user, the control authority shall perform the repeat sampling and analysis unless it notifies the user of the violation and requires the user to perform the repeat analysis. Resampling is not required if:
(1) The control authority performs sampling at the industrial user at a frequency of at least once per month, or
(2) The control authority performs sampling at the user between the time when initial sampling was conducted and the time when the results of the initial sampling are received.
