(iii) Table 1 of 40 CFR 141.202(a) (Items (5), (6), and (8))--To
require public water systems to give a Tier 1 public
[[Page 578]]
notice (rather than a Tier 2 or Tier 3 notice) for violations or
situations listed in Appendix A of Subpart Q of Part 141 of this
chapter;
(iv) 40 CFR 141.202(b)(3)--To require public water systems to comply
with additional Tier 1 public notification requirements set by the State
subsequent to the initial 24-hour Tier 1 notice, as a result of their
consultation with the State required under Secs. 141.202(b)(2);

for consultation by the public water system to determine whether a Tier
1 (rather than a Tier 2) notice is required for a turbidity MCL
violation under Sec. 141.13(b) or a SWTR/IESWTR TT violation due to a
single exceedance of the maximum allowable turbidity limit;
(x) 40 CFR 141.205(c)--To determine the specific multilingual
requirement for a public water system, including defining ``large
proportion of non-English-speaking consumers.''
(b) Requirements for States to adopt 40 CFR part 141, subpart H
Filtration and Disinfection. In addition to the general primacy
requirements enumerated elsewhere in this part, including the
requirement that State provisions are no less stringent than the federal
requirements, an application for approval of a State program revision

(3) Sanitary survey. In addition to the general requirements for
sanitary surveys contained in Sec. 142.10(b)(2), an application must
describe how the State will implement a sanitary survey program that
meets the requirements in paragraphs (b)(3)(i) through (v) of this
section. For the purposes of this paragraph, ``sanitary survey'' means
an onsite review of the water source (identifying sources of
contamination using results of source water assessments where
available), facilities, equipment, operation, maintenance, and
monitoring compliance of a public water system to evaluate the adequacy
of the system, its sources and operations and the distribution of safe
drinking water.

systems (including groundwater under the influence) that address the
eight sanitary survey components listed in paragraphs (b)(3)(i)(A)
through (H) of this section no less frequently than every three years
for community systems and no less frequently than every five years for
noncommunity systems. The State may allow sanitary surveys conducted
after December 1995 to serve as the first set of required sanitary
surveys if the surveys address the eight sanitary survey components
listed in paragraphs (b)(3)(i)(A) through (H) of this section.

a system has outstanding performance and is thus eligible for sanitary
surveys at a reduced frequency.
(iii) Components of a sanitary survey may be completed as part of a
staged or phased state review process within the established frequency.
(iv) When conducting sanitary surveys for systems required to comply
with the disinfection profiling requirements in Sec. 141.172 of this
chapter, the State must also review the disinfection profile as part of
the sanitary survey.
(v) In its primacy application, the State must describe how it will
decide whether a deficiency identified during a sanitary survey is
significant for the purposes of paragraph (b)(1)(ii) of this section.
(c) Total coliform requirements. In addition to meeting the general
primacy requirements of this part, an application for approval of a
State program revision that adopts the requirements of the national
primary drinking water regulation for total coliforms must contain the

non-community water systems using ground water and serving 1,000 persons
or fewer)--A description of how the State will determine whether it is
appropriate to reduce the total coliform monitoring frequency for such
systems using the criteria in Sec. 141.21(a)(3)(i) and how it will
determine the revised frequency.
(iii) Section 141.21(a)(3)(ii) (Reduced monitoring for non-community
water systems using ground water and serving more than 1,000 persons)--A
description of how the State will determine whether it is appropriate to
reduce the total coliform monitoring frequency for non-community water
systems using only ground water and serving more than 1,000 persons
during any month the system serves 1,000 persons or fewer and how it
will determine the revised frequency.
(iv) Section 141.21(a)(5) (Waiver of time limit for sampling after a

approval of a State program revision that adopts 40 CFR part 141,
Subpart P Enhanced Filtration and Disinfection--Systems Serving 10,000
or More People, must contain the information specified in this
paragraph:
(1) Enforceable requirements. States must have the appropriate rules
or other authority to require PWSs to conduct a Composite Correction
Program (CCP) and to assure that PWSs implement any followup
recommendations that result as part of the CCP. The CCP consists of two
elements--a Comprehensive Performance Evaluation (CPE) and Comprehensive
Technical Assistance (CTA). A CPE is a thorough review and analysis of a
plant's performance-based capabilities and associated administrative,
operation and maintenance practices. It is conducted to identify factors
that may be adversely impacting a plant's capability to achieve
compliance and emphasizes approaches that can be implemented without
significant capital improvements. A CTA is the performance improvement
phase that is implemented if the CPE results indicate improved
performance potential. During the CTA phase, the system must identify
and systematically address plant-specific factors. The CTA is a
combination of utilizing CPE results as a basis for followup,
implementing process control priority-setting techniques and maintaining
long-term involvement to systematically train staff and administrators.
(2) State practices or procedures. (i) Section 141.172(a)(3) of this
chapter--How the State will approve a more representative annual data
set than the data set determined under Sec. 141.172 (a)(1) or (2) of
this chapter for the purpose of determining applicability of the
requirements of Sec. 141.172 of this chapter.
(ii) Section 141.172(b)(5) of this chapter--How the State will
approve a method to calculate the logs of inactivation for viruses for a
system that uses either chloramines or ozone for primary disinfection.
(iii) Section 141.172(c) of this chapter--How the State will consult
with PWSs to evaluate modifications to disinfection practice.
(iv) Section 141.173(b) of this chapter--For filtration technologies
other than conventional filtration treatment, direct filtration, slow
sand filtration, or diatomaceous earth filtration, how the State will
determine that a public water system may use a filtration technology if
the PWS demonstrates to the State, using pilot plant studies or other
means, that the alternative filtration technology, in combination with
disinfection treatment that meets the requirements of Sec. 141.172(b) of
this chapter, consistently
[[Page 584]]
achieves 99.9 percent removal and/or inactivation of Giardia lamblia
cysts and 99.99 percent removal and/or inactivation of viruses, and 99
percent removal of Cryptosporidium oocysts. For a system that makes this
demonstration, how the State will set turbidity performance requirements
that the system must meet 95 percent of the time and that the system may
not exceed at any time at a level that consistently achieves 99.9
percent removal and/or inactivation of Giardia lamblia cysts, 99.99
percent removal and/or inactivation of viruses, and 99 percent removal
of Cryptosporidium oocysts.
(h) Requirements for States to adopt 40 CFR part 141, subpart L. In
addition to the general primacy requirements elsewhere in this part,
including the requirement that State regulations be at least as
stringent as federal requirements, an application for approval of a
State program revision that adopts 40 CFR part 141, subpart L, must
contain a description of how the State will accomplish the following
program requirements:
(1) Section 141.64(b)(2) of this chapter (interim treatment
requirements). Determine any interim treatment requirements for those

(2) Section 141.130(c) of this chapter (qualification of operators).
Qualify operators of public water systems subject to 40 CFR part 141,
subpart L. Qualification requirements established for operators of
systems subject to 40 CFR part 141, subpart H--Filtration and
Disinfection may be used in whole or in part to establish operator
qualification requirements for meeting 40 CFR part 141, subpart L
requirements if the State determines that the 40 CFR part 141, subpart H
requirements are appropriate and applicable for meeting subpart L
requirements.
(3) Section 141.131(c)(2) of this chapter (DPD colorimetric test
kits). Approve DPD colorimetric test kits for free and total chlorine
measurements. State approval granted under Sec. 141.74(a)(2) of this
chapter for the use of DPD colorimetric test kits for free chlorine
testing is acceptable for the use of DPD test kits in measuring free
chlorine residuals as required in 40 CFR part 141, subpart L.
(4) Sections 141.131(c)(3) and (d) of this chapter (State approval
of parties to conduct analyses). Approve parties to conduct pH, bromide,
alkalinity, and residual disinfectant concentration measurements. The
State's process for approving parties performing water quality
measurements for systems subject to 40 CFR part 141, subpart H
requirements in paragraph (b)(2)(i)(D) of this section may be used for
approving parties measuring water quality parameters for systems subject
to subpart L requirements, if the State determines the process is
appropriate and applicable.

enumerated elsewhere in this part, including the requirement that the
State provisions are no less stringent than the federal requirements, an
application for approval of a State program revision that adopts 40 CFR
part 141, Sec. 141.76 Recycle Provisions must contain the information
specified in this paragraph:
(1) State practices or procedures. (i) Section 141.76(d) of this
chapter--States must have the proper rules and authority to use Sanitary
Surveys, comprehensive performance evaluations (CPEs), other
inspections, or other activities to evaluate recycle data maintained by
systems under Sec. 141.76(d) of this chapter and require modifications
to recycle practices.
(ii) [Reserved]

(j) Requirements for States to adopt 40 CFR part 141, Subpart T--
Enhanced Filtration and Disinfection--Systems Serving Fewer than 10,000
People. In addition to
[[Page 585]]
the general primacy requirements enumerated elsewhere in this part,
including the requirement that State provisions are no less stringent
than the Federal requirements, an application for approval of a State
program revision that adopts 40 CFR part 141, Subpart T Enhanced
Filtration and Disinfection--Systems Serving Fewer than 10,000 People,
must contain the information specified in this paragraph:
(1) Enforceable requirements. States must have rules or other
authority to require systems to participate in a Comprehensive Technical
Assistance (CTA) activity, the performance improvement phase of the
Composite Correction Program (CCP). The State must determine whether a
CTA must be conducted based on results of a CPE which indicate the
potential for improved performance, and a finding by the State that the
system is able to receive and implement technical assistance provided
through the CTA. A CPE is a thorough review and analysis of a system's
performance-based capabilities and associated administrative, operation
and maintenance practices. It is conducted to identify factors that may
be adversely impacting a plant's capability to achieve compliance.
During the CTA phase, the system must identify and systematically
address factors limiting performance. The CTA is a combination of
utilizing CPE results as a basis for follow-up, implementing process
control priority-setting techniques and maintaining long-term
involvement to systematically train staff and administrators.
(2) State practices or procedures. (i) Section 141.530-141.536--How
the State will approve a more representative data set for optional TTHM
and HAA5 monitoring and profiling.
(ii) Section 141.536 of this chapter--How the State will approve a
method to calculate the logs of inactivation for viruses for a system
that uses either chloramines, ozone, or chlorine dioxide for primary
disinfection.
(iii) Section 141.542 of this chapter--How the State will consult
with the system and approve significant changes to disinfection
practices.
(iv) Section 141.552 of this chapter--For filtration technologies
other than conventional filtration treatment, direct filtration, slow
sand filtration, or diatomaceous earth filtration, how the State will
determine that a public water system may use a filtration technology if
the PWS demonstrates to the State, using pilot plant studies or other
means, that the alternative filtration technology, in combination with
disinfection treatment that meets the requirements of Sec. 141.72(b) of
this chapter, consistently achieves 99.9 percent removal and/or
inactivation of Giardia lamblia cysts and 99.99 percent removal and/or
inactivation of viruses, and 99 percent removal of Cryptosporidium
oocysts. For a system that makes this demonstration, how the State will
set turbidity performance requirements that the system must meet 95
percent of the time and that the system may not exceed at any time at a
level that consistently achieves 99.9 percent removal and/or
inactivation of Giardia lamblia cysts, 99.99 percent removal and/or
inactivation of viruses, and 99 percent removal of Cryptosporidium
oocysts.

Effective Date Note 1: At 65 FR 76751, Dec. 7, 2000, Sec. 142.16 was
amended by adding and reserving paragraphs (i), (j), and (k) and by
adding a new paragraph (l), effective Dec. 8, 2003. For the convenience
of the user, the added text is set forth as follows:
Sec. 142.16 Special primacy requirements.
* * * * *
(l) An application for approval of a State program revision for
radionuclides which adopts the requirements specified in
Sec. 141.26(a)(2)(ii)(C) of this chapter must contain the following (in
addition to the general primacy requirements enumerated in this part,
including that State regulations be at least as stringent as the Federal
requirements):
(1) If a State chooses to use grandfathered data in the manner
described in Sec. 141.26(a)(2)(ii)(C) of this chapter, then the
[[Page 586]]
State must describe the procedures and criteria which it will use to
make these determinations (whether distribution system or entry point
sampling points are used).
(i) The decision criteria that the State will use to determine that
data collected in the distribution system are representative of the
drinking water supplied from each entry point to the distribution
system. These determinations must consider:
(A) All previous monitoring data.
(B) The variation in reported activity levels.
(C) Other factors affecting the representativeness of the data (e.g.
geology).
(ii) [Reserved]
(2) A monitoring plan by which the State will assure all systems
complete the required monitoring within the regulatory deadlines. States
may update their existing monitoring plan or use the same monitoring
plan submitted for the requirements in Sec. 142.16(e)(5) under the
national primary drinking water regulations for the inorganic and
organic contaminants (i.e. the phase II/V rules). States may note in
their application any revision to an existing monitoring plan or note
that the same monitoring plan will be used. The State must demonstrate
that the monitoring plan is enforceable under State law.
Effective Date Note 2: At 66 FR 7066, Jan. 22, 2001, Sec. 142.16 was
amended by revising paragraph (e) introductory text and adding
paragraphs (j) and (k), effective Jan. 22, 2004. For the convenience of
the user, the revised and added text is set forth as follows:

141.32, 141.40, 141.61 and 141.62 for an existing regulated contaminant
must contain the following (in addition to the general primacy
requirements enumerated elsewhere in this part, including the
requirement that State regulations be at least as stringent as the
federal requirements):
(1) If a State chooses to issue waivers from the monitoring
requirements in Secs. 141.23, 141.24, and 141.40, the State shall
describe the procedures and criteria which it will use to review waiver
applications and issue wavier determinations. The State shall provide
the same information required in paragraph (e)(1)(i) and (ii) of this
section. States may update their existing waiver criteria or use the
requirements submitted under the National Primary Drinking Water
Regulations for the inorganic and organic contaminants (i.e., Phase II/V
rule) in 16(e) of this section. States may simply note in their
application any revisions to existing waiver criteria or note that the
same procedures to issue waivers will be used.
(2) A monitoring plan by which the State will ensure all systems
complete the required monitoring by the regulatory deadlines. States may
update their existing monitoring plan or use the same monitoring plan
