(A) 
Within either one hundred eighty (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 users currently discharging to or scheduled to discharge to the POTW shall submit to the DCO a report which contains the information listed in Subsection (C), below.
(B) 
At least ninety (90) days prior to commencement of their discharge, new sources, and sources that will become categorical users subsequent to the promulgation of an applicable categorical standard, shall submit to the DCO a report which contains the information listed in Subsection (C), below. A new source shall:
(1) 
Report the method of pretreatment it intends to use to meet applicable categorical standards; and
(2) 
Give estimates of its anticipated flow and quantity of pollutants to be discharged.
(C) 
Users described above shall submit the information set forth below.
(1) 
Identifying information.
The name and address of the facility, including the name of the operator and owner.
(2) 
Environmental permits.
A list of all environmental control permits held by or for the facility.
(3) 
Description of operations.
A brief description of the nature, average rate of production, and standard industrial classifications (SIC codes) and/or North American Industry Classifications (NAICS) of the operation(s). This description should include a schematic process diagram that indicates points of discharge to the POTW from the regulated processes.
(4) 
Flow measurement.
Information showing the measured or estimated 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 wastestream formula set out in 40 CFR 403.6(e).
(5) 
Measurement of pollutants.
(a) 
The categorical pretreatment standards applicable to each regulated process (and any new categorically regulated processes for existing sources).
(b) 
The results of sampling and analysis identifying the nature and concentration, and/or mass, where required by the standard or by the DCO, of regulated pollutants in the discharge from each regulated process.
(c) 
Instantaneous, daily maximum, and long-term average concentrations, or mass, where required, shall be reported.
(d) 
The sample shall be representative of daily operations and shall be analyzed in accordance with procedures set out in section 171.38 of this chapter. Where the standard requires compliance with a BMP or pollution prevention alternative, the user shall submit documentation as required by the DCO or the applicable standards to determine compliance with the standard.
(e) 
If discharge flow conditions are representative of daily operations, the user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this section. The DCO may require additional representative sampling to be conducted.
(f) 
Representative 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 § 304.6(e) to evaluate compliance with pretreatment standards.
(g) 
The DCO 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.

(Ordinance 4229 adopted 9/24/2024)
(A) 
Any user who commences the discharge of hazardous waste shall notify the DCO, 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 § 261.
(1) 
Such notification must include the name of the hazardous waste as set forth in 40 CFR § 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other).
(2) 
If the user discharges more than 100 kilograms of such waste per calendar month to the POTW, the notification also shall contain the following information to the extent such information is known and readily available to the user:
(a) 
An identification of the hazardous constituents contained in the wastes;
(b) 
An estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month; and
(c) 
An estimation of the mass of constituents in the wastestream expected to be discharged during the following twelve (12) months.
(3) 
All notifications must take place not later than one hundred and eighty (180) days after the discharge commences.
(a) 
Any notification under this paragraph need be submitted only once for each hazardous waste discharged.
(b) 
Notifications of changed conditions must be submitted under section 171.33 of this chapter.
(4) 
The notification requirement in this section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of sections 171.29, 171.31, and 171.32 of this chapter.
(B) 
Dischargers are exempt from the requirements of subsection (A), above, during a calendar month in which they discharge not 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 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 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 substance as a hazardous waste, the user must notify the DCO, TRA, the EPA Regional Waste Management Waste Division Director, and state hazardous waste authorities 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 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.
(E) 
This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this chapter, a permit issued thereunder, or any applicable federal or state law.
(Ordinance 4229 adopted 9/24/2024)
(A) 
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 § 136, and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. A written chain-of-custody record of sample possession and quality assurance/quality control shall be maintained.
(B) 
If 40 CFR § 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 applicable sampling and analytical procedures, including procedures suggested by the DCO, the EPA, TCEQ, or other parties approved by EPA.
(C) 
The DCO may require that approved laboratories be used for analysis.
(Ordinance 4229 adopted 9/24/2024)
(A) 
Except as indicated in paragraphs 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 DCO. 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, 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 section 171.29 and 171.31 [40 CFR § 403.12(b) and (d)], a minimum of four (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 does not exist; for facilities for which historical sampling data are available, the DCO may authorize a lower minimum. For the reports required by section 171.32 (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.
(Ordinance 4229 adopted 9/24/2024)
(A) 
Written reports will be deemed to have been submitted on the date postmarked.
(B) 
For reports which are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, or submitted by another method approved by the DCO, the date of receipt of the report shall govern.
(Ordinance 4229 adopted 9/24/2024)
(A) 
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, and documentation associated with best management practices (BMPs) established in this chapter.
(B) 
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.
(C)
