(a) 
Unless exempted by the director, users required to complete a wastewater discharge application and others determined necessary because of special conditions specified by the director shall provide sampling facilities of types and at locations approved by the director.
(b) 
The sampling facilities must be designed to allow inspection, sampling, and flow measurement, if required, of the user’s specific discharges and must be provided and maintained in a safe and operational condition at the user’s expense. The sampling facilities must allow collection in accordance with the requirements of 40 CFR part 136 as amended.
(c) 
Except in cases where the location is impractical or would cause undo hardship to the user, the sampling facilities shall be located on the user’s premises. In such cases, the city may allow the facility to be constructed on the sidewalk or public street provided that the location will not be obstructed in any manner.
(d) 
Adequate room must be provided at or near the facility to allow accurate sampling and preparation of samples.
(e) 
All sampling facilities shall be constructed in accordance with applicable local construction standards.
(f) 
Construction of sampling facilities shall be completed within a time period designated by the director.
(g) 
Failure to provide proper sampling facilities shall be grounds for denial of a permit and/or enforcement action, including denial of the right to discharge to the POTW(s).
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a) 
The volume of flow discharged by a significant industrial user or user shall be based upon metered water consumption as shown by the meter readings maintained by the city.
(b) 
Any significant industrial user or other user as deemed necessary by the director who procures any or all of its water from sources other than the city and all or part of which is discharged into the POTW(s), and who does not have an effluent meter shall install and maintain at the user’s expense a water meter at each unmetered water source.
(c) 
Where it can be shown to the satisfaction of the director that a substantial portion of the water as measured by the aforesaid meter does not enter the sanitary sewer of the city, the director may permit or require the installation of additional meters in a manner as to measure the actual water volume entering the POTW(s) of the city.
(d) 
Whenever meters other than those provided by the city are used for measuring flows to the POTW(s), the meters shall:
(1) 
Be installed and maintained at the user’s expense.
(2) 
Be of a type approved by the director.
(3) 
Be read monthly and calibrated at the user’s expense at a frequency designated by the director. Record of these readings and calibrations must be maintained for inspection and use by the city.
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a) 
All pollutant analyses, including sampling techniques, submitted as part of a wastewater discharge application or report, shall be performed in accordance with the techniques prescribed in 40 CFR part 136 as amended, unless otherwise specified in the categorical pretreatment standard. If 40 CFR part 136 does not contain sampling or analytical techniques for the pollutant in question, or EPA does not recommend use of the 40 CFR part 136 techniques for the pollutant in question, sampling and analyses must be performed in accordance with procedures approved by EPA.
(b) 
The director shall have the right to require a user to submit quality control analyses performed in conjunction with any analysis submitted as required by this division or by a wastewater discharge permit. If quality control information is not available or does not meet the criteria specified in the approved technique, the submitted data can be rejected and the user required to resubmit samples for analysis.
(c) 
All analyses performed under the analytical methods and sampling conditions (i.e. preservation, holding time) specified in 40 CFR part 136 and required by this division or wastewater discharge permit must be submitted to the director in compliance with a schedule established by the director and must be representative of the user’s discharge. Failure to report valid data required by the director will be considered a violation of this division.
(d) 
If more frequent analyses for regulated pollutants are performed by the user using the techniques and at the appropriate sampling location specified in this division or the wastewater discharge permit, the results must be included in the reports submitted to the director.
(e) 
Non-detectable results can only be used to demonstrate a pollutant is not present if the EPA approved method from 40 CFR part 136 with the lowest minimum detection level for that pollutant was used in the analysis.
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a) 
The director will designate samples collection procedures and the number of samples to be collected over the course of discharge required to satisfy reporting requirements. Data submitted must be 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.
(b) 
Except as indicated in subsections (c) and (d) below, 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 director. Where time-proportional composites sampling or grab sampling is authorized by the city, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified by 40 CFR part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited in the field or at the laboratory prior to the analysis for cyanide, total phenols, and sulfides; 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 discharge limits.
(c) 
Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.
(d) 
For sampling required in support of baseline monitoring and 90-day compliance reports required in sections 13-2-261 and 13-2-263, 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 do not exist; for facilities for which historical sampling data are available, the director may authorize a lower minimum. For the reports required by section 13-2-264, the user is required to collect the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.
(e) 
Sample collection information, including but not limited to collection site, sample collector, type of sample, date and time of collection, and sample preservation shall be gathered and submitted along with the analytical data required by this division. Appropriately completed chain of custody forms must be submitted.
