Current through Register Vol. 48, No. 38, September 20, 2024
a) A supplier required to conduct source
water monitoring under Section
611.1001 must submit a sampling
schedule that specifies the calendar dates on which it will collect each
required sample.
1) The supplier must submit
sampling schedules no later than three months prior to the applicable date
listed in Section 611.1001(c) for
each round of required monitoring.
2) Submission of the Sampling Schedule to
USEPA
A) A supplier serving 10,000 or more
people must submit its sampling schedule for the initial round of source water
monitoring under Section
611.1001(a) to
USEPA electronically into the Data Collection and Tracking System (DCTS)
through USEPA's Central Data Exchange (CDX).
BOARD NOTE: The supplier must register with the CDX to use
the DCTS. For information see "Step-by-Step Guide to the Data Collection and
Tracking System (DCTS)", USEPA, Office of Water (4606) (document number EPA
815/B-08-001), available from USEPA, National Center for Environmental
Publications, www.epa.gov/nscep (search
"815B08001"); telephone 888-890-1995; or e-mail helpdesk@epacdx.net.
B) If a supplier is unable to
submit the sampling schedule into the DCTS, the supplier may use an alternative
approach for submitting the sampling schedule that USEPA has approved in
writing.
3) A supplier
serving fewer than 10,000 people must submit to the Agency its sampling
schedules for the initial round of source water monitoring Section
611.1001(a).
4) A supplier must submit to the Agency
sampling schedules for the second round of source water monitoring required by
Section 611.1001(b).
5) If USEPA or the Agency does not respond to
a supplier regarding its sampling schedule, the supplier must sample at the
reported schedule.
b) A
supplier must collect samples within two days before or two days after the
dates indicated in its sampling schedule (i.e., within a five-day period around
the schedule date) unless one of the conditions of subsection (b)(1) or (b)(2)
applies.
1) If an extreme condition or
situation exists that may pose danger to the sample collector, or one that
cannot be avoided and that causes the supplier to be unable to sample in the
scheduled five-day period, the supplier must sample as close to the scheduled
date as is feasible, unless the Agency approves an alternative sampling date in
a SEP. The supplier must submit an explanation for the delayed sampling date to
the Agency concurrent with the shipment of the sample to the
laboratory.
2) Replacement Samples
A) If a supplier 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 Section
611.1004; or the failure of an
approved laboratory to analyze the sample, then the supplier must collect a
replacement sample.
B) The supplier
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 supplier demonstrates that collecting a replacement sample
within this time frame is not feasible or the Agency approves an alternative
resampling date in a SEP. The supplier must submit an explanation for the
delayed sampling date to the Agency concurrent with the shipment of the sample
to the laboratory.
c) A supplier that fails to meet the criteria
of subsection (b) for any source water sample required under Section
611.1001 must revise its
sampling schedule to add dates for collecting all missed samples. A supplier
must submit the revised schedule to the Agency for approval prior to collecting
the missed samples.
