10 CSR 60-7.020 - Reporting Requirements for Lead and Copper Monitoring
PURPOSE: This rule establishes requirements for reports of water sample analyses and monitoring for lead and copper.
(1) Reporting
requirements for lead and copper tap water monitoring and for water quality
parameter monitoring.
(A) Except as provided
in paragraph (1)(A)7. of this rule, a water system shall report to the
department the information required by this subsection for all tap water
samples and all water quality parameter samples specified in
10
CSR 60-15.080 within the first ten (10) days following
the end of each applicable monitoring period specified in
10
CSR 60-15.070,
10
CSR 60-15.080, and
10
CSR 60-15.090 (such as, every six (6) months,
annually, or every three (3) years). For monitoring periods with a duration
less than six (6) months, the end of the monitoring period is the last date
samples can be collected during that period as specified in
10
CSR 60-15.070 and
10
CSR 60-15.080. The water system shall report-
1. The results of all tap samples for lead
and copper including the location of each site and the criteria under
10
CSR 60-15.070(1) under which the site
was selected for the system's sampling pool;
2. Documentation for each tap water lead or
copper sample for which the water system requests invalidation pursuant to
10
CSR 60-15.070(6);
3. The ninetieth percentile lead and copper
concentrations measured from among all lead and copper tap water samples
collected during each monitoring period (calculated in accordance with
10 CSR
60-15.010(3)(C) ), unless the
department calculates the system's ninetieth percentile lead and copper levels
under section (8) of this rule;
4.
With the exception of initial tap sampling conducted pursuant to
10
CSR 60-15.070(4)(A), the system shall
specify any site which was not sampled during previous monitoring periods and
include an explanation of why sampling sites have changed;
5. The results of all tap samples for pH and,
where applicable, alkalinity, calcium, conductivity, temperature, and
orthophosphate or silica collected under
10
CSR 60-15.080(2)-(5);
6. The results of all samples collected at
the entry point(s) to the distribution system for applicable water quality
parameters under
10
CSR 60-15.080(2)-(5); and
7. A water system shall report the results of
all water quality parameter samples collected under
10
CSR 60-15.080(3)-(6) during each six-
(6-) month monitoring period specified in
10
CSR 60-15.080(4) within the first ten
(10) days following the end of the monitoring period unless the department has
specified a more frequent reporting requirement.
(B) For a non-transient noncommunity water
system, or a community water system meeting the criteria of
10 CSR
60-15.060(2)(G) and that does not
have enough taps that can provide first-draw samples, the system must either-
1. Provide written documentation to the
department identifying standing times and locations for enough non-first-draw
samples to make up its sampling pool under
10
CSR 60-15.070(2)(E) by the start of
the first applicable monitoring period under
10
CSR 60-15.070(4) that commences after
April 11, 2000, unless the department has waived prior department approval of
non-first-draw sample sites selected by the system pursuant to
10
CSR 60-15.070(2)(E); or
2. If the department has waived prior
approval of non-first-draw sample sites selected by the system, identify, in
writing, each site that did not meet the six- (6-) hour minimum standing time
and the length of standing time for that particular substitute sample collected
pursuant to
10
CSR 60-15.070(2)(E) and include this
information with the lead and copper tap sample results required to be
submitted pursuant to paragraph (1)(A)1. of this rule.
(C) At a time specified by the department, or
if no specific time is designated by the department, then as early as possible
prior to the addition of a new source or any long-term change in water
treatment, a water system deemed to have optimized corrosion control under
10
CSR 60-15.020(3)(C), a water system
subject to reduced monitoring pursuant to
10
CSR 60-15.070(4)(D), or a water
system subject to a monitoring waiver pursuant to
10
CSR 60-15.070(7) shall submit written
documentation to the department describing the change or addition. The
department must review and approve the addition of a new source or long-term
change in treatment before it is implemented by the water system. Examples of
long-term treatment changes include the addition of a new treatment process or
modification of an existing treatment process. Examples of modifications
include switching secondary disinfectants, switching coagulants (for example,
alum to ferric chloride), and switching corrosion inhibitor products (for
example, orthophosphate to blended phosphate). Long-term changes can include
dose changes to existing chemicals if the system is planning long-term changes
to its finished water pH or residual inhibitor concentration. Long-term
treatment changes would not include chemical dose fluctuations associated with
daily raw water quality changes.
(D) Any small system applying for a
monitoring waiver under
10
CSR 60-15.070(6), or subject to a
waiver granted pursuant to
10
CSR 60-15.070(6)(C), shall provide
the following information to the state in writing by the specified deadline:
1. By the start of the first applicable
monitoring period in
10
CSR 60-15.070(4), any small water
system applying for a monitoring waiver shall provide the documentation
required to demonstrate that it meets the waiver criteria of
10
CSR 60-15.070(6)(A)-(B);
2. No later than nine (9) years after the
monitoring previously conducted pursuant to
10
CSR 60-15.070(6)(B) or
10
CSR 60-15.070(6)(D) 1., each small
system desiring to maintain its monitoring waiver shall provide the information
required by
10
CSR 60-15.070(6)(D) 1. and 2.;
and
3. No later than sixty (60)
days after it becomes aware that it is no longer free of lead-containing and/or
copper-containing material, as appropriate, each small system with a monitoring
waiver shall provide written notification to the state, setting forth the
circumstances resulting in the lead-containing and/or copper-containing
materials being introduced into the system and what corrective action, if any,
the system plans to remove these materials.
(E) Each groundwater system that limits water
quality parameter monitoring to a subset of entry points under
10
CSR 60-15.080(3)(C) ) shall provide,
by the commencement of such monitoring, written correspondence to the
department that identifies the selected entry points and includes information
sufficient to demonstrate that the sites are representative of water quality
and treatment conditions throughout the system.
(2) Source Water Monitoring Reporting
Requirements.
(A) A water system shall report
the sampling results for all source water samples collected in accordance with
10
CSR 60-15.090 within the first ten (10) days following
the end of each source water monitoring period (that is, annually, per
compliance period, per compliance cycle) specified in 10 CSR
6015.090.
(B) With the exception of
the first round of source water sampling conducted pursuant to
10
CSR 60-15.090(2), the system shall
specify any site which was not sampled during previous monitoring periods and
include an explanation of why the sampling point has changed.
