(a) Except as specified in Section 915.37(b), all Significant Industrial Users must, at a frequency determined by the Director submit no less than twice per year, June 1st and December 1st, 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 Waste Minimization Plan alternative, the User must submit documentation required by the Director or the Pretreatment Standard necessary to determine the compliance status of the User.
(b) The City may authorize an Industrial User, subject to a Categorical Pretreatment Standard to forego sampling of a Pollutant regulated by a Categorical Pretreatment Standard if the Industrial User has demonstrated through sampling and other technical factors that the Pollutant is neither present nor expected to be present in the Discharge, or is present only at background levels from intake water and without any increase in the Pollutant due to activities of the Industrial User. This authorization is subject to the following conditions:
(1) The waiver may be authorized where a Pollutant is determined to be present solely due to Domestic Sewage discharged from the facility provided that the Domestic Sewage is not regulated by an applicable Categorical Standard and otherwise includes no process Wastewater.
(2) The monitoring waiver is valid only for the duration of the effective period of the WDP, but in no case longer than 5 years. The User must submit a new request for the waiver before the waiver can be granted for each subsequent WDP. See Section 915.23 (a) (8).
(3) In making a demonstration that a Pollutant is not present, the Industrial User must provide data from at least one sampling of the facility’s process Wastewater prior to any treatment present at the facility that is representative of all Wastewater Discharges from all processes.
(4) The request for a monitoring waiver must be signed in accordance with Section 915.04 (a) (4), and include the certification statement in 915.47 (a) (40 CFR 403.6(a)(2)(ii)).
(5) Non-detectable sample results may be used only as a demonstration that a Pollutant is not present, if the EPA approved method from 40 CFR Part 136 with the lowest minimum detection level for that Pollutant was used in the analysis.
(6) Any grant of the monitoring waiver by the Director must be included as a condition in the User’s permit. The reasons supporting the waiver and any information submitted by the User in its request for the waiver must be maintained by the Director for 3 years after expiration of the waiver.
(7) Upon approval of the monitoring waiver and revision of the User’s permit by the Director, the Industrial User must certify on each report with the statement in Section 915.47 ( c), that there has been no increase in the Pollutant in its waste stream due to activities of the Industrial User.
(8) In the event that a waived Pollutant is found to be present or is expected to be present because of changes that occur in the User’s operations, the User must immediately: Comply with the monitoring requirements of Section 915.37 (a), or other more frequent monitoring requirements imposed by the Director, and notify the Director.
(9) This provision does not supersede certification processes and requirements established in Categorical Pretreatment Standards, except as otherwise specified in the Categorical Pretreatment Standard.
(c) The City may reduce the requirement for periodic compliance reports to a requirement to report no less frequently than once a year, unless required more frequently in the Pretreatment Standard or by the USEPA/Ohio EPA, where the Industrial User’s total categorical Wastewater flow does not exceed any of the following:
(1) Five hundred (500) gallons per day, whichever is smaller, as measured by a continuous effluent flow monitoring device unless the Industrial User Discharges in batches;
(2) One (1.0) lb. per day of organic Discharge; and
(3) Maximum allowable Discharge loading for any pollutant regulated by the applicable categorical Pretreatment Standard for which approved Local Limits were developed in accordance with Section 915.12
of this Ordinance and are either non detectable or below limits as set forth in table below:

Reduced reporting is not available to Industrial Users that have in the last two (2) years been in Significant Noncompliance, as defined in Section 915.51 of this Ordinance. 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 Director, decreasing the reporting requirement for this Industrial User would result in data that is not representative of conditions occurring during the reporting period.
(d) All periodic compliance reports must be signed and certified in accordance with Section 915.47 (a) of this Ordinance.
(e) 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.
(f) 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 Director, using the procedures prescribed in Section 915.44 of this Ordinance, the results of this monitoring shall be included in the report.
(g) Users that send electronic (digital) documents to the City to satisfy the requirements of this Section, periodic compliance reports, must follow up electronic submittals with transmittal of information in writing to the Director. The Director shall accept periodic compliance reports, in electronic format without violation of time requirements so long as the sender transmits the required document within five (5) business days in written format. All other correspondence with the City specific to requirements of this Ordinance shall be in written format.
