(A) Except as specified in division (C) of this section, all users must, at a frequency determined by the Superintendent submit no less than twice per year (June and December or on dates specified) reports indicating the nature, concentration of pollutants in the discharge which are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. In cases where the pretreatment standard requires compliance with a Best Management Practice (BMP) or pollution prevention alternative, the user must submit documentation required by the superintendent or the pretreatment standard necessary to determine the compliance status of the user.
(B) The city or Superintendent may reduce the requirement for periodic compliance reports (see division (A) and 40 C.F.R. 403.12(e)(1)) to a requirement to report no less frequently than once a year, unless required more frequently in the pretreatment standard or by the EPA/state or other authority including, but not limited to the Superintendent, where the industrial user’s total categorical wastewater flow does not exceed any of the following:
(1) 5,000 gallons per day, as measured by a continuous effluent flow monitoring device unless the industrial user discharges in batches;
(2) 0.37 pounds per day of BOD (or biochemical oxygen demand); and
(3) 0.01% of the maximum allowable headworks loading for the pollutants as set forth below:
MAHL* mg/L | 0.01% mg/L |
MAHL* mg/L | 0.01% mg/L | |
Arsenic | 2.649 | 0.0003 |
Cadmium | 0.949648 | 0.00009 |
Chromium | 117.313 | 0.012 |
Hex Chromium | 22.21776 | 0.0002 |
Copper | 2.0016 | 0.0002 |
Cyanide | 0.45601 | 0.00005 |
Iron | 155.0470154 | 0.0155 |
Lead | 1.55124 | 0.0002 |
Mercury | 1.140912 | 0.0001 |
Nickel | 5.56327 | 0.0006 |
Silver | 4.62438 | 0.0005 |
Zinc | 7.68471 | 0.0008 |
* Denotes maximum allowable headworks loading | ||
(4) Reduced reporting is not available to industrial users that have in the last two years been in significant noncompliance, as defined in § 55.006. In addition, reduced reporting is not available to an industrial user with daily flow rates, production levels, or pollutant levels that vary so significantly that, in the opinion of the Superintendent, decreasing the reporting requirement for this industrial user would result in data that are not representative of conditions occurring during the reporting period.
(C) All periodic compliance reports must be signed and certified in accordance with § 55.158(A).
(D) All wastewater samples must be representative of the user’s discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
(E) If a user subject to the reporting requirement in this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Superintendent, using the procedures prescribed in § 55.155, the results of this monitoring shall be included in the report.
