Lincoln Municipal Code Art. X Reporting Requirements

(a) Within either 180 days after 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 categorical industrial users currently discharging to or scheduled to discharge to the POTW shall submit to the public works director a report which contains the information listed in subsection (b), below. At least 90 days prior to commencement of their discharge, new sources, and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical pretreatment standard, shall submit to the public works director a report which contains the information listed in subsection (b), below. A new source shall report the method of pretreatment it intends to use to meet applicable categorical standards. A new source also shall give estimates of its anticipated flow and quantity of pollutants to be discharged.

(b) Users described above shall submit the information set forth below:

(1) All information required in Section 13.08.838(a)(1), (2), (3) and (6) per 40 CFR 403.12(b)(1)—(7);

(2) Measurement of pollutants.

a. The user shall provide the information required in Section 13.08.838(a)(7) (a) through (d).

b. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this section.

c. 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 wastestream formula in 40 CFR 403.6(e) to evaluate compliance with the pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e) this adjusted limit along with supporting data shall be submitted to the public works director;

d. Sampling and analysis shall be performed in accordance with Sections 13.08.876 and 13.08.878;

e. The public works director 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;

f. The baseline report shall indicate the time, date and place of sampling and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW.

(3) Compliance certification. A statement, reviewed by the user's authorized representative as defined in Section 13.08.021 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 (O&M) and/or additional pretreatment is required to meet the pretreatment standards and requirements.

(4) Compliance schedule. If additional pretreatment and/or O&M will be required to meet the pretreatment standards, the shortest schedule by which the user will provide such additional pretreatment and/or O&M must be provided. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. A compliance schedule pursuant to this section must meet the requirements set out in Section 13.08.862.

(5) Signature and report certification. All baseline monitoring reports must be certified in accordance with Section 13.08.882 and signed by an authorized representative as defined in Section 13.08.021.

(Ord. No. 992B, § 1, 6-25-2019)

The following conditions shall apply to the compliance schedule required by Section 13.08.860(b)(4):

(a) The schedule shall contain progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (such events include, but are not limited to, hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, and beginning and conducting routine operation);

(b) No increment referred to above shall exceed nine months;

(c) The user shall submit a progress report to the public works director no later than 14 days following each date in the schedule and the final date of compliance including, as a minimum, whether or not it complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the user to return to the established schedule; and

(d) In no event shall more than nine months elapse between such progress reports to the public works director.

(Ord. No. 992B, § 1, 6-25-2019)

Within 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 such pretreatment standards and requirements shall submit to the public works director a report containing the information described in Section 13.08.838(a)(6) and (7) and 13.08.860(b)(2). For users subject to equivalent mass or concentration limits established in accordance with the procedures in Section 13.08.812, this report shall contain a reasonable measure of the user's long-term production rate. For all other users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period. All compliance reports must be signed and certified in accordance with Section 13.08.882. All sampling will be done in conformance with Section 13.08.878.

(Ord. No. 992B, § 1, 6-25-2019)

(a) Significant industrial users must submit 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. The reports shall be submitted no less than twice per year in June and December unless required more frequently by the city. In cases where the pretreatment standard requires compliance with a best management practice (BMP) or pollution prevention alternative, the user must submit the documentation necessary to determine the compliance status of the user as required by the public works director and the pretreatment standard.

(b) All periodic compliance reports must be signed and certified in accordance with Section 13.08.882.

(c) All wastewater samples must be representative of the user's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and always maintained in good working order. 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.

(d) 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 public works director, using the procedures prescribed in Section 13.08.878, the results of this monitoring shall be included in the report.

(Ord. No. 992B, § 1, 6-25-2019)

Each user must notify the public works director of any significant changes to the user's operations or system which might alter the nature, quality, or volume of its wastewater at least 90 days before the change.

(a) The public works director may require the user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a wastewater discharge permit application under Section 13.08.838.

(b) The public works director may issue a new individual wastewater discharge permit under Article IX or modify an existing wastewater discharge permit under Section 13.08.854 in response to changed conditions or anticipated changed conditions.

(Ord. No. 992B, § 1, 6-25-2019)

(a) In the case of any discharge, including, but not limited to, accidental discharges, discharges of a non-routine, episodic nature, a non-customary batch discharge, a slug discharge or slug load, that might cause potential problems for the POTW, the user shall immediately telephone and notify the public works director of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user.

(b) A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees who to call in the event of a discharge described in subsection (a), above. Employers shall ensure that all employees, who could cause such a discharge to occur, are advised of the emergency notification procedure.

(c) Significant industrial users must notify the public works director immediately of any changes at its facility affecting the potential for a slug discharge.

(Ord. No. 992B, § 1, 6-25-2019)

All users not required to obtain an individual wastewater discharge permit shall provide appropriate reports to the as the public works director may require.

(Ord. No. 992B, § 1, 6-25-2019)

If sampling performed by a user indicates a violation, the user must notify the public works director within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the public works director within 30 days after becoming aware of the violation. Resampling by the industrial user is not required if the city performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the city receives the results of this sampling.

(Ord. No. 992B, § 1, 6-25-2019)

All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the EPA determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the public works director or other parties approved by EPA.

(Ord. No. 992B, § 1, 6-25-2019)

Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report, based on data that is representative of conditions occurring during the reporting period.

(a) Except as indicated in subsections (b) and (c) of this section, the user must collect wastewater samples using 24-hour flow proportional composite sampling techniques, unless time proportional composite sampling or grab sampling is authorized by the public works director. Where time proportional composite sampling or grab sampling is authorized by the city, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the city, as appropriate. In addition, grab samples may be required to show compliance with instantaneous limits.

(b) Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.

(c) For sampling required in support of baseline monitoring and 90-day compliance reports required in Sections 13.08.860 and 13.08.864, a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the public works director may authorize a lower minimum. For the compliance reports required by Section 13.08.866 (per 40 CFR 403.12(e) and 403.12(h)), the industrial user is required to collect the number of grab samples necessary to assess and assure compliance by with applicable pretreatment standards and requirements.

(Ord. No. 992B, § 1, 6-25-2019)

Written reports will be deemed to have been submitted on the date postmarked. For reports, which are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, the date of receipt of the report shall govern.

(Ord. No. 992B, § 1, 6-25-2019)

Users subject to the reporting requirements of this chapter shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this chapter, and any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements. Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three years. This period shall be automatically extended for the duration of any litigation concerning the user or the city, or where the user has been specifically notified of a longer retention period by the public works director.

(Ord. No. 992B, § 1, 6-25-2019)

Certification of permit applications and user reports. The following certification statement is required to be signed and submitted by users submitting permit applications in accordance with Section 13.08.840; users submitting baseline monitoring reports under Section 13.08.860 (b) (5); users submitting reports on compliance with the categorical Pretreatment Standard deadlines under Section 13.08.864; and users submitting periodic compliance reports required by Section 13.08.866 (a) and (d). The following certification statement must be signed by an Authorized Representative as defined in Section 13.08.021:
