The city shall determine which users are subject to paying the industrial cost recovery charges, in the following manner:
(A) The city shall require appropriate employees of the sewage works to review billing records and prepare a list of all potential industrial users, as identified in each of the divisions listed in § 51.100, above.
(B) The list of all potential industrial users shall be analyzed on the basis of data available at the sewage works billing office (for example, type of business, volume charges, excessive loading charges, estimated number of employees, and the like) for the purpose of developing preliminary lists of probable industrial and probable nonindustrial users.
(C) The city shall conduct an immediate survey of all probable industrial users in order to substantiate the validity of classifying a particular user as an industrial user. Users initially classified as an industrial user shall be notified as to their classification.
(D) After completing the survey of all probable industrial users, the city shall review the list of probable nonindustrial users to determine if the initial classification of any of these users should be reconsidered. Where appropriate, individual users will be contacted in order to determine the proper classification.
(E) After an industrial user has been notified of his classification, the user may request reconsideration by furnishing data and measurements acceptable to the city for the determination of sewage discharges. The city shall have the right to measure and determine the strength and content of all sewage and waste discharges, either directly or indirectly, into the city's sanitary sewage system, in such manner and by such method as it may deem practicable in the light of the conditions and attending circumstances of each case in order to determine the proper user classification.
(F) Within a reasonable period of time following completion of the sewage works construction project, the city shall have completed the initial classification of all industrial users. During the first calendar year of operation, subsequent to completion of the construction project, and annually thereafter, the city will review, classify and reclassify all users as either industrial or nonindustrial users based upon measurements and data obtained by the city or furnished by individual users. Normally, each user will retain his classification until the next succeeding classification period. However, if there is a substantial change in the strength, volume or delivery flow rate characteristics introduced into the treatment works by an individual user, then the classification of that user may be reviewed and established during the year in the light of the conditions and attending circumstances of each case.
