Sampling and sample splitting.

A. The Chief Plant Operator and/or Superintendent of Sewers shall have the power to take samples and do necessary analysis to determine the nature and concentration of wastes. Whenever sewage, industrial wastes or other wastes are believed to have characteristics other than those prescribed for sanitary sewage as defined in Article II herein, or are believed to contain toxic substances or other material or substances excluded from the Town of Webster's Sewer Use Law, and are being discharged into the Town's sewers or public sewers tributary thereto from any premises, the Chief Plant Operator and/or Superintendent of Sewers shall have the right to reassess his determinations by taking samples and tests at any time or by periodic rechecks, without notice to the person discharging such wastes.B.

Samples shall be taken and flow measurements made at the monitoring stations or other locations provided in accordance with § 257-100 of this chapter.C. In the event that a control manhole or manholes have not been required, the samples shall be taken at a suitable and accessible point or points to be selected by the Chief Plant Operator and/or Superintendent of Sewers that are specifically identified with the user.D. When so requested in advance by an industrial user, and when taking a sample of industrial wastewater, the Town's representative(s) shall gather a sufficient volume of sample so that the sample can be split into two nearly equal volumes, each of a size adequate for the anticipated analytical protocols, including any quality control procedures.

One of the volumes shall be given to the industry whose wastewater was sampled, and the other shall be retained by the Town for its own analysis. These samples will be tested at the expense of the user.E. All samples shall be tested by a NYSDOH-certified lab in accordance with procedures in 40 CFR Part 136 and shall be accompanied by a chain of custody or as specified in the permit.F. In cases where results between labs on the same sample are different, the average of the two results shall be used to determine if there is a violation.
