The owner of any property serviced by a building sewer carrying industrial wastes may, at the discretion of the City, be required to provide laboratory measurements, tests or analyses of waters or wastes to illustrate compliance with this chapter and any special condition for discharge established by the City or regulatory agencies having jurisdiction over the discharge. The number, type and frequency of sampling and laboratory analyses to be performed by the owner shall be as stipulated by the City. The industry must supply a complete analysis of the constituents of the wastewater discharge to assure that compliance with Federal, State and local standards are being met. The owner shall report the results of measurements and laboratory analyses to the City at times and in the manner as prescribed by the City. The owner shall bear the expense of all measurements, analyses and reporting required by the City. At those times as deemed necessary, the City reserves the right to take measurements and supplies for analysis by an independent laboratory.
