(f) 
Where the control authority has imposed mass limitations on industrial users as required by the wastewater discharge permit, the report required by subsections (a)-(d) above shall indicate the mass of pollutants regulated by the industrial user's wastewater discharge permit.
(g) 
For industrial users subject to equivalent mass or concentration limits established by the control authority in accordance with the procedures in 40 CFR 403.6, the report required by subsections (a)-(d) above shall provide a reasonable measure of the user's long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed only on terms of allowable pollutant discharge per unit of production (or other measure of operation), the industrial user shall submit the user's actual average production rate for the reporting period.
(h) 
Requirements specified in section 13.07.501 shall apply for these reports.
(i) 
Categorical industrial users shall submit documentation to demonstrate compliance with a BMP where a required BMP or pollution prevention alternative is part of the categorical standard.
(Ordinance 6444 adopted 1/3/22; Ordinance 6716 adopted 5/6/2024)
(a) 
The reports required in sections 13.07.496(c)(1)–(8), 13.07.498, 13.07.499, and 13.07.502 of this division, shall contain the results of sampling and analysis of the discharge, including the flow rate, nature, and concentration of pollutants contained therein which are limited by the applicable pretreatment standards or industrial user wastewater discharge permit. When required by a pretreatment standard or wastewater discharge permit, the report must contain facility production data and/or mass of pollutants discharged.
This sampling and analysis may be performed by the control authority in lieu of the industrial user. Where the POTW performs all of the requested sampling and analysis in lieu of the industrial user, the POTW must sample at least semiannually. Additionally, the user will not be required to submit the compliance certification required under 40 CFR 403.12(b)(6) and 403.12(d), unless the city deems necessary. In addition, if the POTW collects the information required for the periodic compliance report, including flow data, the industrial user will not be required to submit the reports.
(b) 
If sampling performed by the city indicates a violation, the city shall notify the industrial user within twenty-four (24) hours of becoming aware of the violation. The industrial user shall submit to an increase in sampling and analysis by the control authority at a minimum of once per calendar month, until the control authority determines the industrial user returns to compliance. The sampling and analysis cost incurred due to this increased compliance monitoring shall be the responsibility of the industrial user.
Where the city performs sampling in lieu of the IU and a violation is indicated, the city will resample within thirty (30) days of becoming aware of the violation. The city has the right to notify the IU of the violation and require the IU to perform the repeat sampling and receipt of analysis and submit the results within 30 days of becoming aware of the violation.
(c) 
If sampling performed by an industrial user indicates a violation, the industrial user shall notify the control authority 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 control authority within 30 days of becoming aware of the violation, except the industrial user is not required to resample if:
(1) 
The control authority performs sampling at the industrial user at a frequency of at least once per calendar month; or
(2) 
The control authority performs sampling at the user between the time when the user performs its initial sampling and the time when the user receives the results of this sampling.
(d) 
Samples and measurements taken as required herein shall be representative of the volume and nature of the monitored discharge. All samples shall be taken at the monitoring point(s) specified in the wastewater discharge permit.
(e) 
If a permittee subject to 40 CFR 403.12(e) or (h) monitors any regulated pollutant(s) at the monitoring points designated in the wastewater discharge permit more frequently than required by the permit using test procedures prescribed in 40 CFR 136 or amendments thereto, or otherwise approved by EPA, or as specified in the wastewater discharge permit, the results shall be reported in the periodic compliance report.
(f) 
For sampling that is required in support of baseline monitoring reports (BMRs) and 90-day compliance reports required in sections 13.07.496 and 13.07.498, a minimum of four (4) grab samples are required for pH, cyanide, total phenols, oil and grease (O&G), sulfide, and volatile organic compounds for:
(1) 
New industrial users;
(2) 
Existing industrial users that make changes or install new treatment or existing industrial users for which historical sampling data do not exist; and
(3) 
Where there has been a change to existing IUs, for example, the addition of treatment, historic data that does not represent the current discharge would not be able to be used to justify a lower minimum of grab samples.
(g) 
Industrial users are required to report data obtained through appropriate sampling and analysis performed during the period covered by the report based on data that are representative of conditions occurring during the reporting period.
(Ordinance 6444 adopted 1/3/22)
(a) 
The city shall require appropriate reporting from those industrial users with discharges that are not subject to categorical pretreatment standards. According to 40 CFR 403.12(h), significant noncategorical industrial users shall submit periodic compliance reports to the city, at least once every six months (on dates specified by the city). The frequency for submitting periodic compliance reports will be specified in the IU's wastewater discharge permit. Rationale for reporting frequency will be provided in the permit fact sheet.
(b) 
The periodic compliance reports shall be submitted to the city within twenty (20) days following the end of each reporting period, which shall contain data collected during the reporting period.

(Ordinance 6444 adopted 1/3/22; Ordinance 6716 adopted 5/6/2024)
Each industrial user (IU) is required to notify the city manager of any planned significant changes to the industrial user’s operations or system which might alter the nature, quality, or volume of its wastewater or affect the potential for a slug discharge. These changes include:
(1) 
Planned changes.
The IU is required to notify the city at least thirty (30) days in advance of any facility expansion, process equipment changes, or process modifications, which might alter the character, nature, quality, or volume of its wastewater;
(2) 
Significant production changes.
The IU is required to notify the city within two (2) days from becoming aware of a significant change (+/- 20% from data used to derive numeric limits in permit) in production or flow data for the next calendar month. (Applicable to categorical industries which operate under a wastewater discharge permit incorporating equivalent mass or concentration limits calculated from a production based standard.) Any IU not notifying the city of such an anticipated change will be required to meet the mass concentration limits in its permit that were based on the original estimate of the long-term average production rate established in the permit application;
(3) 
Significant flow or pollutant change.
The IU is required to notify the city within thirty (30) days from becoming aware of a significant change in flow data (+/- 20% from data used to derive numeric limits in permit) or the discharge of any previously unreported pollutants (applicable to all permitted industries);
(4) 
Facility shutdowns.
The IU is required to notify the city at least thirty (30) days in advance or as soon as feasibly possible, but in no case less than five (5) business days prior to any facility shutdown which might alter the character, nature, quality, or volume of its wastewater. Failure to submit this notification prior to the facility shutdown period would constitute a violation;
(5) 
Monitoring location changes.
The monitoring locations specified in the wastewater discharge permit shall not be changed (temporarily or permanently) without notification to and approval by the city;
(6) 
The city manager may require the permitted IU to submit such information as may be deemed necessary to evaluate the changed conditions, including the submission of a wastewater discharge permit application under section 13.07.432 of this division; and
(7) 
The city manager may issue a wastewater discharge permit under section 13.07.434 or modify an existing wastewater discharge permit under section 13.07.464 of this division.
(Ordinance 6444 adopted 1/3/22)
(a) 
Any industrial user shall notify the POTW, the EPA Regional Waste Management Division Director, and the Texas Commission on Environmental Quality 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. Such notification must include the name of the hazardous waste as set forth in 40 CFR part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the industrial user discharges more than one hundred (100) kilograms of such waste per calendar month to the POTW, the notification shall also contain the following information to the extent such information is known and readily available to the industrial user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month, and an estimation of the mass of constituents in the wastestream expected to be discharged during the following twelve (12) months.
All notifications must take place within one hundred eighty (180) days after the discharge commences. Any notification under this paragraph need be submitted only once for each hazardous waste discharged. However, notifications of changed discharges must be submitted under section 13.07.503 which includes 40 CFR 403.12(b), (d), and (e). The notification requirement in this section does not apply to pollutants already reported under the monitoring requirements of section 13.07.496, section 13.07.498, and section 13.07.499, above.
(b) 
Dischargers are exempt from the requirements of subsection (a) of this section during a calendar month in which they discharge no more than fifteen (15) kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than fifteen (15) kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification.
Subsequent months during which the industrial user discharges more than such quantities of any hazardous waste do not require additional notification.
(c) 
In the case of any new regulations under section 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substances as a hazardous waste, the industrial user must notify the POTW and the Texas Commission on Environmental Quality of the discharge of such substance within ninety (90) days of the effective date of such regulations.
(d) 
In the case of any notification made under this section, the industrial user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.
(Ordinance 6444 adopted 1/3/22)
(a) 
All pollutants analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report, shall be performed in accordance with the methods and techniques prescribed in 40 CFR part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. Where 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 analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the city or other parties, approved by the administrator.
(b) 
Environmental laboratories accredited or certified in accordance with section 30 TAC, chapter 25, subchapters A–C, shall perform all pollutant analyses required by this division, except for field data. The list of laboratories accepted by the city will be provided to the user upon request.
(Ordinance 6444 adopted 1/3/22)
(a) 
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 are representative of conditions occurring during the reporting period.
(b) 
Grab samples.
Samples for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds must be obtained using grab collection techniques. 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 analysis as follows:
(1) 
For cyanide, total phenols, and sulfides, the samples may be composited in the laboratory or in the field.
(2) 
For volatile organics and O&G, the samples may be composited in the laboratory (only).
(3) 
Total residual chlorine, pH, and temperature samples cannot be “composited” under any circumstances.
(c) 
Grab samples may be used for compliance where a single grab is reasonably expected to be representative of an IU’s discharge.
(d) 
24-hour composite samples.
For all other pollutants, 24-hour composite samples must be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized in writing by the city.
(1) 
The IU must demonstrate in writing that the time-proportional or grab samples are representative of the discharge before the city may allow the IU to submit such samples.
(2) 
Where time-proportional composite sampling or grab sampling is authorized in writing by the city the samples must be representative of the IU’s wastewater discharge.
(3) 
The decision to allow the alternative sampling or site specific circumstances must be documented in the IU’s file.
(4) 
Composite samples for other parameters unaffected by the compositing procedures, as documented in EPA methodologies, may be authorized in writing by the CA, as appropriate.
(5) 
Grab samples may be substituted for 24-hour composite samples if the IU can demonstrate that its discharge is a homogeneous batch discharge that is a full representation of the IU’s daily discharge of process wastewater.
(e) 
All sampling and analysis shall be performed as outlined in section 13.07.501(d).
(f) 
For sampling facilities that discharge less than 24-hours per day, the sampling must be representative of the IU’s discharge.
(1) 
Sampling must be taken within a 24-hour period; however, the sample should only be collected during that portion of the 24-hour period that the IU is discharging from the regulated process and/or pretreatment unit (as long as regulated process wastewater is flowing through the pretreatment unit).
(2) 
During parts of the day when there is no discharge of process wastewater, standing water should not be disproportionately sampled and analyzed as it would not be representative of the discharge from the IU.
(g) 
The city will prescribe sampling protocols that produces representative results. The selected protocol should take into consideration all of the operation conditions and the physical configuration of the IU facility.
(Ordinance 6444 adopted 1/3/22)
(a) 
Pollutant discharge limits in categorical pretreatment standards can be expressed either as concentration or mass limits. Wherever possible, where mass limits are specified in standards, equivalent concentration limits will be provided so that local, state, or federal authorities responsible for enforcement may use either concentration or mass limits. Limits in categorical pretreatment standards shall apply to the effluent of the process regulated by the standard.
(b) 
When the limit is expressed by the control authority in terms of mass of pollutant per unit of production, this limit may be converted to mass of pollutant discharged per day, or effluent concentration, for purposes of calculating effluent limitations applicable to individual industrial users.
(1) 
When the control authority calculates the mass-per-day limitations, it shall calculate such limitations by multiplying the limits in the standard by the industrial user’s average rate of production. This average rate of production shall be based not upon the designed production capacity, but rather upon a reasonable measure of the industrial user’s actual long-term daily production, such as the average daily production during a representative year. For new sources, actual production shall be estimated using projected production.
(2) 
When the control authority calculates equivalent concentration limitations, it will divide the daily mass limitations determined above by the average daily flow rate of the industrial user’s regulated process wastewater. This average daily flow rate shall be based upon a reasonable measure of the industrial user’s actual long-term average flow rate, such as the average daily flow rate during the representative year.
(3) 
Limits calculated by the control authority in subsections (b)(1) and (2) above shall be deemed pretreatment standards for the purposes of section 307(d) of the Act. Industrial users will be required to comply with the equivalent limitations in lieu of the promulgated categorical standards from which they were derived.
(Ordinance 6444 adopted 1/3/22)
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 U.S. Postal Service, the date of receipt of the report shall govern.
(Ordinance 6444 adopted 1/3/22)
(a) 
Retention of records.
(1) 
The permittee shall retain records of all monitoring information, including all calibration and maintenance records, laboratory reports, operator logs, documentation associated with BMPs, copies of any other reports required by the wastewater discharge permit, and records of all data used to complete the application for this permit, for a period of at least three (3) years from the date of the sample, measurements, report, application or after the expiration date of the permit, whichever is greater.
(2) 
This period of record retention may be automatically extended for the duration of any unresolved litigation concerning compliance with this permit or extended at any time by request from the city.
(3) 
All records that pertain to matters that are the subject of special orders or any other enforcement or litigation activities brought by the city shall be retained and preserved by the permittee until all enforcement activities have concluded and all periods of limitation with respect to any and all appeals have expired.
