(A) Within 180 days after the effective date of a categorical pretreatment standard applicable to an industrial user, or 180 days after the final administrative decision made upon a category determination submission, whichever is later, industrial users subject to the categorical pretreatment standards which are discharging to or which are scheduled to discharge to the POTW shall be required to submit to the Authority Manager a report which contains the information listed in this section.
(B) Where reports containing this information already have been submitted to the appropriate state or federal agency in compliance with the federal requirements, the industrial user will not be required to submit this information.
(C) In addition, at least 90 days prior to commencement of discharge, any industry or structure planning to discharge industrial wastes to the sanitary sewer shall file the material listed below with the Authority Manager. The authority may also require each person who applies for sewer service, receives sewer service, or through the nature of the enterprise creates a potential environmental problem to file the material listed below.
(D) Required information:
(1) General statement. A written statement setting forth the name and address of the facility, including the name of the operator and owners, the nature of the enterprise, the source and amount of water used, and the amount of water to be discharged, with the present or expected bacterial, physical, chemical, radioactive or other pertinent characteristics of the wastes;
(2) Permits. The user shall submit a list of any environmental control permits held by or for the facility;
(3) Description of operations. The user shall submit a brief description of the nature, average rate of production, and standard industrial classification (SIC) of the operations carried out by the industrial user. This description should include a schematic process diagram which indicates points of discharge to the POTW from the regulated processes;
(4) Flow measurement. The user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following: regulated process streams and other streams as necessary to allow use of the combined waste stream formula set forth in the applicable federal regulations. The Authority Manager may allow for verifiable estimates of these flows where justified by cost or feasibility considerations;
(5) Measurement of pollutants. All measurements, tests and analyses of the characteristics of water and wastes to which reference is made in this chapter shall be determined in accordance with methods listed in 40 C.F.R. § 136 or the laboratory procedure set forth in the latest edition, at the time of analysis, of Standard Methods for the Examination of Water and Sewage; provided, in the event of any conflict, 40 C.F.R. § 136 shall be followed. These measurements shall be determined at the control manhole provided for, or upon suitable samples taken at, the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. The following requirements shall also apply to all users:
(a) The user shall identify the categorical pretreatment standards applicable to each regulated process;
(b) In addition, the user shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the standard or Authority Manager) of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations;
(c) A minimum of four grab samples must be used for pH, cyanide, total phenols, oils and grease, sulfide and volatile organics. For all other pollutants, 24-hour composite samples must be obtained through flow-proportional composite sampling techniques where feasible. The Authority Manager may waive flow-proportional composite sampling for any industrial user that demonstrates that flow-proportional sampling is infeasible. In such cases, samples may be obtained through time-proportional composite sampling techniques or through a minimum of four grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged;
(d) The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this division;
(e) Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment, the user should measure the flows and concentrations necessary to allow use of the combined waste stream formula in order to evaluate compliance with the categorical pretreatment standards;
(f) Where 40 C.F.R. § 136 or the most recent edition of Standard Methods for the Examination of Water and Sewage do not contain sampling or analytical techniques for the pollutant in question, or where the Authority Manager determines that the 40 C.F.R. § 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 Authority Manager;
(g) The Authority Manager may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures;
(h) The baseline report shall indicate the time, date and place, of sampling, and methods of analysis, and shall certify that the sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW; and
(i) Sampling shall be carried out by methods listed in 40 C.F.R. § 136 to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether grab sample or samples should be taken. All costs incurred in either industrial self-monitoring or compliance monitoring by the Authority shall be borne by the owner, including fees for inspection and surveillance.
(6) Certification. A statement, reviewed by an authorized representative of the user and certified to by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O and M) or additional pretreatment is required for the industrial user to meet the pretreatment standards and requirements; and
(7) Compliance schedule. If additional pretreatment or O and M will be required to meet the categorical pretreatment standards, the shortest schedule by which the industrial user will provide the additional pretreatment or O and M is required. The completion date in this schedule shall not be later than the compliance date established for the applicable categorical pretreatment standard.
