(A) Applicability. At minimum, all significant industrial users are required to sample based on the frequency stated in the discharge control document. Other users are required to sample upon the request of the village.
(B) Frequency. All users with wastewater discharge permits must sample their effluent and report the results to the POTW at least twice yearly for those parameters specified in the user's permit. The village shall have the right to perform its own sampling at any time.
(C) Sample collection.
(1) Except as indicated in division (2), below, the user must collect wastewater samples using flow proportional composite collection techniques.
(2) In the event flow proportional sampling is infeasible, the Pretreatment Coordinator may authorize the use of time proportional sampling preferably collecting at least 96 aliquots during the 24-hour work day; or a minimum of four grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. A proportional number of samples shall be collected for wastewater discharges less than 24 hours. In addition, grab samples may be required to show compliance with instantaneous discharge limits.
(3) Samples for fats, oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.
