(a) Laboratory procedures used in the examination of industrial wastes shall be those set forth in the latest edition of Standard Methods. However, alternative methods for certain analyses of industrial wastes may be used, subject to mutual agreement between the Superintendent and the owner.
(b) Determination of the character and concentration of the industrial wastes shall be made by the owner responsible for the discharge, or his or her qualified agent, as approved by the Superintendent. The results of the analyses shall be reported to the City, on a monthly basis or as required by the Superintendent, on forms provided by the City. The City may make its own analysis on the wastes, and these determinations shall be binding as a basis for charges, except under the circumstances in the following paragraph.
(c) In case the analyses performed by the industry and the City result in substantially different values, an effort shall be made by the industry to collect samples at the same time the City collects its own samples. Results of the analyses on the samples collected by the City and the industry shall be compared using the same testing procedures outlined in the latest edition of Standard Methods and the differences negotiated.
