A. Planned Changes. The user shall give notice to the director as soon as possible of any planned physical alterations or additions to the permitted facility when:
1. The alteration or addition to a permitted facility may meet one of the criteria for determining whether a facility is a new source.
2. Within ninety days following the date for final compliance with applicable categorical pretreatment standards or, in the case of a new source, following commencement of the introduction of wastewater into the POTW, any user subject to categorical pretreatment standards and requirements shall submit to the director a report indicating the nature and concentration of all pollutants in the discharge from the regulated process.
The report shall state whether the applicable categorical pretreatment standards or requirements are being met and, if not, what additional operations and maintenance or pretreatment is necessary. This statement shall be reviewed by an authorized representative of the user and certified; or
3. Any anticipated facility expansions, production increases, or process modifications which will result in new, different, or increased discharges of pollutants must be reported by submission of a new permit application or, if such changes will not violate the discharge limitations specified in the permit, by notice to the Pima County regional wastewater reclamation department. Following such notice, the permit may be modified to specify and limit any pollutants not previously limited or change existing limits or other requirements. Approval must be obtained prior to any new discharges. The user shall allow forty-five business days for review.
B. Anticipated Noncompliance. The user shall give advance notice to the director of any planned changes in the permitted facility or activity which may result in noncompliance with permit requirements.
C. Transfers. Permits are not transferable to any person except after notice to the director. The director may require modification or reissuance of the permit to change the name of the user and incorporate such other requirements as may be necessary under this chapter.
D. Monitoring Reports. Monitoring results shall be reported at the intervals specified in the permit.
1. Monitoring results must be reported on a self-monitoring report form (SMRF), or a form approved by the director to the extent that the information reported may be entered on the form for the report period.
2. If the user monitors any pollutant more frequently than required by the permit, using test procedures approved under 40 CFR § 136 or as specified in the permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted in the SMRF.
3. Calculations for all limitations which require averaging of measurements shall utilize an arithmetic mean unless otherwise specified by the director in the permit.
4. In cases where the pretreatment standard requires compliance with a best management practice or pollution prevention alternative, the user must submit documentation required by the director or the pretreatment standard necessary to determine the compliance status of the user.
E. Reduced Periodic Reporting. The director 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 EPA/state, where the industrial user's total categorical wastewater flow does not exceed five thousand gallons per day.
Reduced reporting is not available to industrial users that have in the last two years been in significant noncompliance (SNC), as defined in Section 13.36.040 of this chapter. 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 are not representative of conditions occurring during the reporting period.
F. Compliance Schedules. Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of the permit shall be submitted no later than fourteen days following each scheduled date.
