(A) The discharged sewage shall be sampled during each surcharge billing period for a minimum of a one day period, i.e., 24 hours, by means of a composite sample. An extended sampling period of up to one week, i.e., seven continuous days, or reduction may be requested to enable the gathering of a sample representative of a business' sewage. The extension or reduction of the sampling period beyond the initial one day sampling period may be requested by either the sewer user involved or the Board. If an extended sampling period is requested, the parameter values used to calculate the surcharge shall be the arithmetical average of the individual values. If a user has multiple discharges of sewage, each discharge shall be sampled according to quality. The volume of each discharge shall be determined by actual measurement or by means of process usage. If significant process changes are made to affect quality of any discharge, resampling may be requested by either the user involved or the Board.
(B) The sample shall be measured for the following parameters: Carbonaceous Biochemical oxygen demand (CBOD) total suspended solids (TSS) and/or phosphorus. These tests shall be conducted in accordance with the Code of Federal Regulations, Title 40, Part 136, Guideline Establishing Test Procedures for the Analysis of Pollutants.
