(A) Any user subject to a pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new user, after commencement of the discharge into the POTW, shall submit to the Manager during the months of June and December unless required more frequently in the pretreatment standard or by the wastewater contribution permit, 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 Manager and in consideration of such factors as local high or low flow rates, holidays, budget cycles, and the like, the Manager may agree to alter the months during which the above reports are to be submitted.
(B) The Manager may impose mass limitations on users where their composition is appropriate. In such cases, the report required by division (A) above shall indicate 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 and concentration, or production and mass where requested by the Manager of pollutants contained therein which are limited by the applicable pretreatment standards. The frequency of monitoring shall be prescribed in the applicable pretreatment standard. All analyses shall be performed by a laboratory acceptable to the Municipal Utility Commission. Analytical procedures shall be in accordance with procedures established by the U.S. EPA Administrator pursuant to § 304 (g) of the Act and contained in 40 C.F.R. part 136 and amendments thereto or with any other test procedures approved by the U.S. EPA Administrator. Sampling shall be performed in accordance with the techniques approved by the U.S. EPA Administrator.
(C) Where 40 C.F.R. part 136 does not include a sampling or analytical technique for the pollutant in question, sampling and analysis shall be performed in accordance with the procedures set forth in the EPA publication, “Sampling and Analysis Procedures for Screening of Industrial Effluents for Priority Pollutants,” April, 1977, or its most current applicable publication, and amendments thereto, or with any other sampling and analytical procedures approved by the U.S. EPA Administrator.
