A.   The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests, and analyses of waters and wastes to demonstrate compliance with this chapter and any special conditions for discharge established by the district or regulatory agencies having jurisdiction over the discharge.
   B.   The number, type, and frequency of laboratory analyses to be performed by the owner shall be as stipulated by the district, but no less than once a year, the industry must supply a complete analysis of the constituents of the wastewater discharge to assure that compliance with the federal, state, and local standards are being met.
   C.   The owner shall report the results of measurements and laboratory analyses to the district at such times and in such manner as prescribed by the district. The owner shall bear the expense of all measurements, analyses, and reporting required by the district. At such times as deemed necessary, the district reserves the right to take measurements and samples for analysis.
   D.   All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of "Standard Methods For The Examination Of Water And Wastewater", published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
   E.   Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewerage works and to determine the existence of hazards to life, limb, and property. (The particular analyses involved will determine whether a 24 hour composite sample or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24 hour composite samples, whereas, pHs are determined from periodic grab samples.) (Ord. 81-O-8, 6-5-1981)
