(A) Flow proportional sampling. The user or customer must collect wastewater samples using flow proportional composite collection techniques. In the event flow proportional sampling is not feasible, the town may authorize the use of time proportional sampling or a minimum of four grab samples where the user or customer demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.
(B) Grab sampling. Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic chemicals must be obtained using grab collection techniques.
(C) Timing. Written reports will be deemed to have been submitted on the date post-marked. For reports which are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, the date of receipt of the report shall govern.
