(A) Any user subject to a pretreatment standard, after the compliance date of the pretreatment standard, or, in the case of a new user, after commencement of the discharge into the POTW shall submit, to the Superintendent, 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 the 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 Superintendent and in consideration of those factors as local high or low flow rates, holidays, budget cycles, and the like, the Superintendent may agree to alter the months during which the above reports are to be submitted.
(B) (1) The Superintendent may impose mass limitations on users where their imposition is appropriate. In these cases, the report required by § 30.087 shall indicate the mass of pollutants regulated by pretreatment standards in the effluent of the user.
(2) The industrial user shall notify the POTW immediately of any slug loading as defined herein by the industrial 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 Superintendent, of pollutants contained therein which are limited by the applicable pretreatment standards. All analyses shall be performed by a laboratory acceptable to the city. Analytical procedures shall be in accordance with procedures established by the U.S. EPA Administrator pursuant to Section 304(g) of the Act and contained in 40 CFR, 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 CFR, 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, and amendments thereto, or with any other sampling and analytical procedures approved by the U.S. EPA Administrator.
(D) A Baseline Monitoring Report (BMR) must be submitted to the Superintendent by all categorical industrial users at least ninety (90) days prior to initiation of discharge to the sanitary sewer. The BMR must contain, at a minimum, the following:
(1) Production data. A process description, SIC code number, raw materials used, chemicals used, final product, pretreatment industrial category and a schematic which indicates points of discharge to the sewer system.
(2) Identifying information to include name, address of facility, owner(s), contact person, and any other permits held by the facility.
(3) Wastewater characteristics. Total plant flow, types of discharges, average, and maximum flows from each process.
(4) Nature/concentration of pollutants. Analytical results for all pollutants regulated by this article and/or any applicable federal pretreatment standard and sample type and location. All analyses must conform to 40 CFR, Part 136 and amendments thereto.
(5) Information concerning any pretreatment equipment used to treat the facility’s discharge.
(6) New sources shall give estimates of the information requested in subparagraphs (3) and (4) above, but at no time shall a new source commence discharge(s) to the public sewer of substances that do not meet the provisions of this article. All new sources must be in compliance with all provisions of this article, state, and federal pretreatment regulations prior to commencement of discharge to the public sewer.
(E) The reports required by subparagraphs (A), (B), (C), and (D) must be signed by an authorized representative of the industrial user.
