Current through Register Vol. 48, No. 38, September 20, 2024
a) A GWS supplier must provide the Agency, at
the Agency's request, any existing information that will enable the Agency to
conduct a sanitary survey.
b) For
the purposes of this Subpart S, a "sanitary survey", as conducted by the
Agency, includes an onsite review of the delineated WHPAs (identifying sources
of contamination within the WHPAs and evaluations of the hydrogeologic
sensitivity of the delineated WHPAs conducted under source water assessments or
utilizing other relevant information if available), facilities, equipment,
operation, maintenance, and monitoring compliance of a PWS to evaluate the
adequacy of the system, its sources and operations and the distribution of safe
drinking water.
c) The sanitary
survey must include an evaluation of the applicable components listed in
subsections (c)(1) through (c)(8):
1)
Source;
2) Treatment including any
corrosion control treatment and water quality parameters;
3) Distribution system;
4) Finished water storage;
5) Pumps, pump facilities, and
controls;
6) Monitoring, reporting,
and data verification;
7) System
management and operation; and
8)
Operator compliance with Agency requirements.
d) The Agency must repeat the sanitary survey
as follows:
1) The Agency must conduct a
sanitary survey that addresses the eight sanitary survey components listed in
subsection (c) no less frequently than every three years for a CWS supplier,
except as provided in subsection (d)(3), and every five years for a non-CWS
supplier. The Agency may conduct more frequent sanitary surveys for any
supplier. The sanitary survey must include an evaluation of each of the
elements set forth in subsection (c), as applicable.
2) The Agency may use a phased review process
to meet the requirements of subsection (d)(1) if all the applicable elements of
subsection (c) are evaluated within the required interval.
3) The Agency may conduct sanitary surveys
once every five years for CWSs under any of the following circumstances:
A) If the system either provides at least
4-log treatment of viruses (using inactivation, removal, or an Agency-approved
combination of 4-log inactivation and removal) before or at the first customer
for all its groundwater sources; or
B) If the supplier has an outstanding
performance record, as determined by the Agency and documented in previous
sanitary surveys, and the supplier had no history of total coliform MCL or
monitoring violations under former Sections
611.521 through
611.527 since the last sanitary
survey.
4) This
subsection (d)(4) corresponds with
40 CFR
142.16(o)(2)(iv), which
imposes requirements for describing the elements of the State's regulatory
system. This statement maintains structural consistency with the corresponding
federal provision.
5) The Agency
must provide a GWS supplier with written notice in a SEP that describes any
significant deficiency that it has found no later than 30 days after the Agency
has identified the significant deficiency. The notice may specify corrective
actions and deadlines for completion of corrective actions. The Agency may
provide the written notice at the time of the sanitary survey.
BOARD NOTE: Subsections (a) through (c) derive from
40 CFR
141.401. Subsection (d) derives from
