18 AAC 80.415 - Repeat monitoring

The requirements of 40 C.F.R. 141.858, adopted by reference in 18 AAC 80.010(a), apply to repeat monitoring. In addition,

(1) under 40 C.F.R. 141.858(a)(1), the department will, on a case-by-case basis, extend the 24-hour time limit if the owner or operator notifies the department about a logistical problem in collecting the repeat samples within 24 hours that is due to unusual and unpredictable circumstances beyond the owner's or operator's control and that makes meeting the 24-hour requirement impossible; for an extension under this paragraph, the department will specify how much time the public water system has to collect repeat samples; and
(2) repeat samples must be collected from the repeat sampling sites designated in the system's sample siting plan as set out in 18 AAC 80.410.
