All interceptors shall be of a type and capacity approved by the Council, and shall be located so as to be readily and easily accessible for cleaning and inspection. In maintaining these interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the Council. Disposal of the collected materials performed by owner’s personnel or currently licensed waste disposal firms must be in accordance with currently acceptable State Pollution Control Agency (MPCA) rules and regulations.

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 and with the federal regulations of 40 C.F.R. part 136, “Guidelines Establishing Test Procedures for Analysis of Pollutants”, as amended from time to time. Sampling methods, location, time, durations and frequencies are to be determined on an individual basis subject to approval by the Council. Determination of the character and concentration of the industrial wastes shall be made by the person discharging them, or the person’s agent, as designated and required by the Council. The Council may also make its own analyses on the wastes, and these determinations shall be binding as a basis for sewer service charges.
(2004 Code, § 53.057) (Ord. 781, passed 7-19-1988)
