§ 18-175.   Sampling Procedures and Reporting Criteria for Industrial/Commercial Users.
   1.   All industrial/commercial users shall submit at lease quarterly to the Borough a certified statement of the characteristics of its wastewater discharged into the sewers and treatment works of the Borough or into any sewers connected to its treatment works. This statement shall be filed with the Borough no later than the tenth day of the month following the quarter for which the report is required.
   2.   The waste characteristics to be measured and certified by the user shall be determined by the Borough and specified in the industrial/commercial waste permit.
   3.   Whenever required by the Borough, the owner of any property served by a building sewer carrying wastewater and material shall install a large manhole or sampling chamber in the building sewer in accordance with plants and specifications approved by the Borough and install and maintain it at all times at the user’s expense. There shall be ample room in each sampling chamber to accurately sample and composite samples for analysis. The chamber shall be safely, easily and independently (of other premises and buildings of user) accessible to authorized representatives of the Borough at all times. Where construction of a sampling chamber is not economically or otherwise feasible in the opinion of the Borough, alternative arrangements for sampling may be made at the discretion of the Borough.
   4.   Each sampling chamber shall contain a Parshall flume, weir or similar device with a recording and totalizing register for measuring liquid quantity; or the metered water supply to the industrial plant may be used as a measure of liquid quantity where it is substantiated by the Borough that the metered water supply and waste quantities are approximately the same or where a measurable adjustment agreed to by the Borough is made in the metered water supply to determine the liquid waste quantity.
   5.   Samples shall be taken as deemed appropriate by the Borough. Such sampling shall be done as prescribed by the Borough to insure representative quantities for the entire reporting period.
   6.   The sampling frequency, sampling chamber, metering device, sampling methods, and analyses of samples shall be subject, at any time to inspection and verification by the Borough.
   7.   All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this Section shall be determined in accordance with the standard methods specified by this Part or with any other method approved by the Borough.
   8.   The Borough shall consider all information regarding an industrial user’s effluent characteristics as being nonconfidential and may make all such information available to the public without restriction, unless the user specifically requests and is able to demonstrate to the satisfaction of the Borough that the release of such information would divulge information processes or methods of production entitled to protection as trade secrets of the user.
   9.   In the event that the Borough deems it necessary to conduct its own tests of wastewaters discharged by any user, the Borough may take or have made any such tests and the user shall reimburse the Borough for the full cost thereof.
   10.   Within 90 days following the date for final compliance with applicable pretreatment standards, or in the case of a new source, following commencement of the introduction of wastewater into the sanitary sewer system, any user subject to pretreatment standards and requirements shall submit to the Borough a report indicating the nature and concentration of all pollutants in the discharge from the regulated process which are limited by pretreatment standards and requirements and the average and maximum daily flow for these process units in the user facility which are limited by such pretreatment standards or requirements. This report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional operation and maintenance and/or pretreatment is necessary to bring the user into compliance with all no applicable pretreatment standards and requirements. This statement shall be signed by an authorized representative of the industrial/commercial user, and certified to by a qualified professional.
   11.   Any user subject to a pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the sanitary sewer system, shall submit to the Borough during the months of June and December, unless required more frequently in the pretreatment standard or by the Borough, a report indicating the nature and concentration of pollutants in the effluent which are limited by such pretreatment standards. In addition, this report shall include a record of all daily flows which during the reporting period exceeded the average daily flow. At the discretion of the Borough and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the Borough may agree to alter the months during which the above reports are to be submitted.
   12.   The Borough may impose mass limitations on users which are using dilution to meet applicable pretreatment standards or requirements, or in other cases where the imposition of mass limitations are appropriate. In such cases, the report required by subsection .10 of this Section shall include the mass of pollutants regulated by pretreatment standards in the effluent of the user. These reports shall contain the results of sampling and analysis of the discharge, including the flow and the nature of concentration, or production and mass where requested by the Borough, of pollutants contained therein which are limited by the applicable pretreatment standards. The frequency of monitoring shall be prescribed in accordance with procedures established by the administrator pursuant to §304(g) of the Act and contained in 40 CFR, Part 136, and amendments thereto or with any other test procedures approved by the administrator. Sampling shall be performed in accordance with the techniques approved by the administrator.
