Pollutant concentrations disputed by user.

In the event that the pollutant concentration of the waste discharged from a premises to a Sewer District sewer or public sewer tributary thereto as determined under § 257-103 of this article is disputed by a user, a program of resampling and gauging with subsequent chemical and physical analysis may be instituted as follows:A. The user must submit a request for resampling and gauging of the wastes to the Chief Plant Operator and/or Superintendent of Sewers and bind himself to bear all of the expense incurred by the Sewer District in the resampling and gauging and subsequent analysis of the wastewater.B.

A consultant or agency of recognized professional standing in the employment of the person must confer with representatives of the Chief Plant Operator and/or Superintendent of Sewers in order that an agreement may be reached as to the various factors which must be considered in a new sampling program.C. The consultant or agency of recognized professional standing employed by the person must be present or represented during its sampling operation, unless waived by the Chief Plant Operator and/or Superintendent of Sewers.D. Resampling must be performed when all waste-producing processes are contributing wastes containing pollutants at normal/representative rate.E.

The results of the resampling and reanalysis by an approved laboratory approved by the Chief Plant Operator and/or Superintendent of Sewers shall be considered to be the current analysis of the wastewater discharged to the Sewer District or public sewers tributary thereto and shall be used for determining the surcharge and/or acceptability of the wastewater.
