best available data shall be used to compute the charges at the dis- cretion of the Superintendent. No part of this ordinance shall be interpreted to prevent non-flow-weighted composite or grab sampling whenever necessary or required to monitor or check any user for compliance with this ordinance. B. SAMPLE ANALYSIS Wastewater and waste samples will be collected and tests per- formed by City personnel wherever feasible. The laboratory proce- dures to be used in the examination of industrial or other wastes or wastewater will be those set forth in "Standard Methods" as previously defined in this ordinance. However, alternate methods for certain analysis may be used when approved by the Superintendent. For pretreatmer_t purposes, samples shall be taken at least twice yearly by the City of the user if so designated by the Superintendent. These two samples shall be paid for by the user. Samples for the purpose of checking compliance shall be paid for by the City if no violation is found and by the user if a violation occurred. User shall also pay for samples to check violations. User may use the two regular samples in the required compliance reporting. The Superintendent may at his discretion: 1) have the user sample at his discharge and have analysis done at a mutually agreeable laboratory; 2) sample and send to a competent commercial or public labo- ratory for analysis. Any necessary quality assurance for pretreatment sampling and analysis shall be consistent with those of 40 CFR 136 -"Guidelines for Establishing Test Procedures for the Analysis of Pollutants", et_seq. C. MONITORING FACILITIES 'I'he City shall require to be provided and operated at the user's own cost and expense monitoring facilities to allow inspection, sampling, and flow measurement of the building sewer and/or internal drain systems. The monitoring facility should normally be located on the user's premises; however, when such location would be impractical or cause undue hardship on the user, the City may allow the construction of the facility in the public street or sidewalk area in a location that will not be obstructed by landscaping or parked vehicles. The above shall apply to both old and new users when monitoring facilities are necessary. VVhether constructed on public or private property, the sampling and monitoring facilities shall be provided in accordance with the city's requirements and all applicable local construction standards and specifications. There shall be ample room in or near such control manhole or facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling equipment and measuring devices shall be maintained at all times in a safe and proper operating condition at the expense of the user. Plans and specifications for constructions of monitoring facilities shall conform to City standards and shall be approved by the City Engineer. Rental or lease of suitable equipment on an as-needed basis in lieu of permanent installation may be acceptable subject to approval by the Superintendent; such approval shall not release the user from the requirement to provide sampling facilities secured and protected access to the control point(s). 17
