005.01 Systems
required to conduct source water monitoring must submit a sampling schedule
that specifies the calendar dates when the system will collect each required
sample.
25-005.01A Systems must submit
sampling schedules to the Department no later than three months prior to the
applicable date listed in 179 NAC 25-004.03 02 or 40 CFR 141 Subpart
W.
25-005.01B If the Department
does not respond to a system regarding its sampling schedule, the system must
sample at the reported schedule.
005.02 Systems must collect samples within
two days before or two days after the dates indicated in their sampling
schedule (i.e., within a five-day period around the schedule date) unless one
of the conditions of 179 NAC 25-005.02 item 1 or 2 applies.
1. If an extreme condition or situation
exists that may pose danger to the sample collector, or that cannot be avoided
and causes the system to be unable to sample in the scheduled five-day period,
the system must sample as close to the scheduled date as is feasible unless the
Department approves an alternative sampling date. The system must submit an
explanation for the delayed sampling date to the Department concurrent with the
shipment of the sample to the laboratory.
2. Other Possible Conditions
a. If a system is unable to report a valid
analytical result for a scheduled sampling date due to equipment failure, loss
of or damage to the sample, failure to comply with the analytical method
requirements, including the quality control requirements in 179 NAC
25-007, or the failure of an approved
laboratory to analyze the sample, then the system must collect a replacement
sample.
b. The system must collect
the replacement sample not later than 21 days after receiving information that
an analytical result cannot be reported for the scheduled date unless the
system demonstrates that collecting a replacement sample within this time frame
is not feasible or the Department approves an alternative resampling date. The
system must submit an explanation for the delayed sampling date to the
Department concurrent with the shipment of the sample to the
laboratory.
005.03 Systems that fail to meet the criteria
of 179 NAC 25-005.02 for any required source water sample must revise their
sampling schedules to add dates for collecting all missed samples. Systems must
submit the revised schedule to the Department for approval prior to when the
system begins collecting the missed samples.
