Section 22-219.3 Test guidelines.
(a) All measurements, tests and analyses of the characteristics
of water and wastes shall be
determined using analytical procedures approved in 40 CFR Part 136 and amendments thereto.
(b) Except as indicated in paragraph (c) below, the user
must collect wastewater samples using
flow proportional composite collection techniques. In the event flow proportional sampling is
infeasible, the director may authorize the use of time proportional sampling or a minimum of four
(4) grab samples where the user 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.
(c) Samples for oil and grease, temperature, pH, cyanide,
phenols, sulfides, and volatile
organic compounds must be obtained using grab collection techniques.
