The City shall assess an industrial cost recovery charge on industrial users to recover the capital costs of additional treatment facilities which are attributable to the costs of treating industrial wastes. The effective date of the charge for industrial cost reocvery is to be a continuing charge beginning January 1, 2003.
Any industrial user which discharges only nonprocessed, segregated domestic wastes, or wastes from sanitary conveniences (for example, the so-called "dry" industries) with less than 25,000 gallons per day of flow shall be excluded from the application of the industrial cost recovery.
Any industrial user may pay its share in one payment or in equal payments over twenty years or over the life of the property or industry, whichever is less. Any industrial user which desires to make one lump sum payment or equal payments on the basis of a time period less than twenty years, must make application for such variance to the City within one year from the effective date of the rate ordinance.
In order that the rates and charges may be justly and equitably adjusted to the service rendered, the City may base its charges not only on volume, but also on the strength and character of the sewage and wastes it is required to treat and dispose of. The City may measure and determine the strength and content of all sewage and wastes discharged, either directly or indirectly, into the City's sanitary sewerage system, in such manner and by such method as it may deem practical in light of the conditions and attending circumstances of the case, in order to determine the proper charge.
To determine the strength of the sewage and wastes, samplings and analyses shall be made from time to time as it is deemed desirable by the City. After charges have been established, based upon the strengths of sewage and wastes, the owner may request reconsideration of these charges by the City by submitting, if requested, analyses of composite samples of the sewage and wastes, certified by a professional engineer or a graduate chemist, subject to such charges. The City may then adjust the charges to the ordinance rates required by such analyses or may recheck the findings by additional sampling and analysis. Requests for rate adjustment may be submitted not more often than once every three months.
All sampling and monitoring of wastewater shall be conducted during periods of normal discharge from industrial users. The determination of BOD, suspended solids, TKN, phosphorus, heavy metals and other toxic substances contained in the wastewater shall be in accordance with the "Standard Methods for the Examination of Water and Wastewater," as prepared by the American Public Health Association, the American Water Works Association and the Water Pollution Control Federation, the most recent edition.
