PART 611 PRIMARY DRINKING WATER STANDARDS
SECTION 611.801 SANITARY SURVEYS FOR GWS SUPPLIERS
Section 611.801 Sanitary Surveys for GWS Suppliers
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 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 40 CFR
142.16(o)(2).
