§ 5.10.120. Reporting requirements for industrial users.

(a)

Within one hundred eighty (180) days after either the effective date of a categorical pretreatment standard or the final administrative decision on a category determination under 40 CFR 403.6(a)(4), whichever is later, existing significant industrial users subject to such categorical pretreatment standards, and currently discharging to or scheduled to discharge to the POTW, shall be required to submit to the director, in addition to the information required by Section 5.10.110(b)(1) through (13), a report which contains the information listed in subsections (1) through (5) of this section. At least ninety (90) days prior to commencement of their discharge, new sources, and sources that become industrial users subsequent to the promulgation of an applicable categorical standard, shall be required to submit to the director, in addition to the information required by Section 5.10.110(b)(1) through (13), a report which contains the information listed in said subsections (1) through (5). A new source shall also be required to report the method of pretreatment it intends to use to meet applicable categorical standards. A new source shall give estimates of its anticipated flow and quantity of pollutants discharged.

(1)

A list of any environmental control wastewater discharge permits held by or for the facility;

(2)

Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary to allow use of the combined waste stream formula set out in 40 CFR 403.6(e);

(3)

The categorical pretreatment standards applicable to each regulated process;

(4)

The results of sampling and analysis identifying the nature and concentration (and/or mass, where required by the categorical standard or by the city) of regulated pollutants in the discharge from each regulated process. Daily maximum and average concentration (or mass, where required) shall be reported. Sampling and analysis shall be performed in accordance with procedures set out in Section 5.10.120(h) and (i);

(5)

A statement reviewed by the industrial user's authorized representative and certified by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis and, if not, whether additional operation and maintenance and/or additional pretreatment is required to meet the pretreatment standards and requirements;

(6)

Signatures and certification in accordance with Section 5.10.110(c).

(b)

Compliance Date Report. Within ninety (90) 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 which are limited by pretreatment standards and requirements and the average and maximum daily flow for those process units in the user facility which are limited by such pretreatment standards or requirements. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional O&M and/or pretreatment is necessary to bring the user into compliance with applicable pretreatment standards or requirements. This statement shall be signed by an authorized representative of the industrial user, and certified to by a qualified professional.

(c)

Periodic Compliance Reports.

(1)

Any industrial user subject to a categorical pretreatment standard, after the compliance date of such standard, or, in the case of a new source, after commencement of the discharge into the POTW, shall submit to the director during the months of June and December, unless required more frequently in the standard or by the director, a report indicating the nature and concentration of pollutants in the effluent which are limited by categorical pretreatment standards. In addition, this report shall include a record of the measured or estimated average and maximum daily flows for the reporting period. At the discretion of the director, and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the director may agree to alter the months during which the above reports are to be submitted.

(2)

The director may impose mass limitations on users to meet applicable pretreatment standards or requirements or in other cases where the imposition of mass limitations is appropriate. In such cases, the report required by subsection (c)(1) of this section shall indicate the mass of regulated pollutants in the effluent of the user.

(3)

Significant non categorical industrial users shall submit to the director during the months of June and December a report of the nature and concentration of the pollutants limited by their wastewater discharge permits and the measured or estimated average and maximum daily flows for the reporting period, unless otherwise stated in their permit.

(4)

All periodic compliance reports required must be signed and certified in accordance with Section 5.10.110(c).

(5)

At the discretion of the director, the sampling and analysis called for in subsections (c)(1) and (3) of this section may be performed by the POTW in lieu of the industrial user. Where the POTW collects all the information required for periodic compliance reports, the industrial user will not be required to submit the report.

(6)

For any regulated pollutant monitored at the sampling location more frequently than required in the permit, the results of this monitoring shall be included in:

i.

Periodic compliance and baseline monitoring reports required for CIUs.

ii.

Periodic compliance reports for any IU not subject to categorical Pretreatment Standards.

(d)

Report of Changed Conditions. All industrial users shall promptly notify the director in advance of any substantial change in the volume or character of pollutants in their discharge, including the listed or characteristic hazardous wastes for which the industrial user has submitted initial notification under 40 CFR 403.12(p). No industrial user shall implement the planned change until approval of the director has been received.

(e)

Notification and Report of Accidental Discharge/Slug Load. In the case of an accidental discharge or slug load which could cause problems to the POTW, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions. Within five days following an accidental discharge or slug load, the user shall submit to the director a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW, fish kills or any other damage to persons or property; nor shall such notification relieve the user of any fines, civil penalties or other liability which may be imposed by this article or other applicable law.

(f)

Notice of Violation/Repeat Sampling and Reporting. If sampling performed by an industrial user indicates a violation, the industrial user must notify the director within twenty-four (24) hours of becoming aware of the violation. The industrial user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the director within thirty (30) days after becoming aware of the violation. The industrial user is not required to resample if the POTW performs monitoring of the industrial user's discharge at least once a month, or if the POTW performs sampling between the time of the industrial user's initial sampling and the time that the industrial user receives the results of this sampling.

(g)

Notification of the Discharge of Hazardous Waste. Following the requirements of 40 CFR 403.12(p), industrial users shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities in writing of any discharge into the POTW of a substance, which, if otherwise disposed of, would be a hazardous waste under 40 CFR part 261.

(h)

Analytical Requirements. All discharge sampling and analysis shall be performed in accordance with EPA approved methods specified in 40 CFR Part 136, unless otherwise specified in an applicable categorical standard. If 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, sampling and analyses must be performed in accordance with procedures approved by EPA.

(i)

Sample Collection.

(1)

Except as indicated in subdivision (2) below, the industrial user must collect wastewater samples using the sampling procedures as defined in 40 CFR 403, Appendix E. — Sampling Procedures. All samples must be obtained through flow proportional composite collection techniques; unless time -proportional composite sampling or grab sampling is authorized by the Control Authority. Where time-proportional composite sampling or grab sampling is authorized, the samples must be representative of the discharge and the decision to allow the alternative sampling must be documented in the IU file. Should grab samples be allowed, the Director will indicate the specific number and timing of the samples that are authorized. In addition, grab samples may be required to show compliance with instantaneous discharge limits.

(2)

Samples for oil and grease, temperature, pH, cyanide, phenols, toxicity, sulfides and volatile organic chemicals must be obtained using grab collection techniques.
