The District may require that any person discharging or proposing to discharge wastewater into the District’s sanitary sewer works file a periodic discharge report. The discharge report may include, but not be limited to, nature of process, volume, rates of flow, mass emission rates, production quantities, hours of operation, number and classification of employees, or other information which relates to the generation of waste including wastewater discharge. Such reports may also include the chemical constituents and quantity of liquid or gaseous materials stored on site even though they are not normally discharged. In addition to discharge reports, the District may require information in the form of wastewater discharge permit applications, self-monitoring reports and other reports contained in §§ 14.18.020 through 14.18.100.

(Ord. 911, § 2, passed 08-24-2015)


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 District sanitary sewer works shall submit to the District Manager a report which contains the information listed in subsection (B) of this section. 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 standard, shall submit to the District Manager a report which contains the information listed in subsection (B) of this section. 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 §§ 14.17.020(A), (G), (K) and (L).

2.    Measurement of Pollutants.

a.    The user shall provide the information required in § 14.17.020(L)(1) through (5);

b.    The user shall take a minimum of 1 representative sample to compile the data necessary to comply with the requirements of this subsection;

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 may be required to 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 District;

d.    Sampling and analysis shall be performed in accordance with §§ 14.16.090(D) and 14.18.130;

e.    The District Manager may allow the submission of a baseline report which utilizes only historical data so long as the data provide information sufficient to determine the need for industrial pretreatment measures;

f.    The baseline report shall indicate the time, method, 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 sanitary sewer works.

C.    Compliance Certification. A statement, reviewed by the user’s authorized representative as defined in § 14.12.010 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.

D.    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 § 14.18.030.

E.    Signature and Report Certification. All baseline monitoring reports must be certified in accordance with § 14.18.120(A) and signed by an authorized representative as defined in § 14.12.010.

(Ord. 911, § 2, passed 08-24-2015)


The following conditions shall apply to the compliance schedule required by § 14.18.020(D):

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 9 months unless specified otherwise;

C.    The user shall submit a progress report to the District Manager 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 9 months elapse between such progress reports to the District Manager.

(Ord. 911, § 2, passed 08-24-2015)


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 sanitary sewer works, any user subject to such pretreatment standards and requirements shall submit to the District Manager a report containing the information described in §§ 14.17.020(K) and (L), and 14.18.020(B)(2). All compliance reports must be signed and certified in accordance with § 14.18.120(A). All sampling will be done in conformance with § 14.18.130.

(Ord. 911, § 2, passed 08-24-2015)


A.    Any SIU subject to a pretreatment standard must, at a frequency determined by the District Manager, submit no less than twice per year (June and December) 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 BMP or pollution prevention alternative, the user must submit documentation required by the District Manager or the pretreatment standard necessary to determine the compliance status of the user. All periodic compliance reports must be signed and certified in accordance with § 14.18.120(A).

B.    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.

(Ord. 911, § 2, passed 08-24-2015)


Each user must notify the District Manager of any significant changes to the user’s operations or system which might alter the nature, quality, or volume of its wastewater at least 45 days before the change.

A.    The District Manager 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 § 14.17.020.

B.    The District Manager may issue an individual wastewater discharge permit or a general permit under § 14.17.090 or modify an existing individual wastewater discharge permit or a general permit under § 14.17.070 in response to changed conditions or anticipated changed conditions.

(Ord. 911, § 2, passed 08-24-2015)


A.    In the case of any discharge, including, but not limited to, accidental discharges, discharges of a nonroutine, episodic nature, a noncustomary batch discharge, a slug discharge or slug load, that might cause potential problems for the sanitary sewer works, the user shall immediately telephone and notify the District Manager 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.    Within 5 days following such discharge, the user shall, unless waived by the District Manager, submit a detailed written report describing the cause(s) 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 might be incurred as a result of damage to the sanitary sewer works, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, penalties, or other liability which may be imposed pursuant to the Sanitary Code.

C.    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) of this section. Employers shall ensure that all employees, who could cause such a discharge to occur, are advised of the emergency notification procedure.

D.    SIUs are required to notify the District Manager immediately of any changes at its facility affecting the potential for a slug discharge.

(Ord. 911, § 2, passed 08-24-2015)


If sampling performed by a user indicates a violation, the user must notify the District Manager 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 District Manager within 30 days after becoming aware of the violation. Resampling by the industrial user is not required if the District performs sampling at the user’s facility at least once a month, or if the District performs sampling at the user’s facility between the time when the initial sampling was conducted and the time when the user or the District receives the results of this sampling, or if the District has performed the sampling and analysis in lieu of the industrial user.

(Ord. 911, § 2, passed 08-24-2015)


Any user who accidentally discharges hazardous waste shall notify the District, the EPA Regional Waste Management Division Director, and state hazardous waste authorities, in writing, of any discharge into the sanitary sewer works of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Discharge of hazardous waste is prohibited under § 14.16.090(A)(15).

(Ord. 911, § 2, passed 08-24-2015)


A.    All periodic compliance reports must be signed and certified in accordance with § 14.18.120(A).

B.    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 District Manager, using the procedures prescribed in § 14.18.130, the results of this monitoring shall be included in the report.

(Ord. 911, § 2, passed 08-24-2015)


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 the Sanitary Code, any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements, and documentation associated with BMPs established under § 14.16.090(G). Records shall include the date, exact place, method, and time of sampling, the name of the analytical techniques or methods used, and the results of such analyses. These records shall remain available for a period of at least 3 years. This period shall be automatically extended for the duration of any litigation concerning the user or the District, or where the user has been specifically notified of a longer retention period by the District Manager.

(Ord. 911, § 2, passed 08-24-2015)

(Ord. 911, § 2, passed 08-24-2015)


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, and 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 District Manager. Where time-proportional composite sampling or grab sampling is authorized by the District, 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 District, 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 §§ 14.18.020 and 14.18.040 (40 CFR 403.12(b) and (d)), a minimum of 4 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 District Manager may authorize a lower minimum. For the reports required by § 14.18.050 (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 with applicable pretreatment standards and requirements.
