Sec. 46.
(a) Reporting requirements for tap water monitoring for lead and copper and for water quality parameter monitoring shall be as follows:
(1) A water system shall report the following
information for all tap water samples within the first ten (10) days following
the end of each applicable monitoring period specified in sections 37 and 38 of
this rule, that is, every six (6) months, annually, every three (3) years, or
every nine (9) years:
(A) The results of all
tap samples for lead and copper, including:
(i) the location of each site; and
(ii) the criteria under:
(AA) section 37(a)(3) through 37(a)(7) of
this rule; or
(BB) which the site
was selected for the system's sampling pool.
(B) Documentation for each tap water lead or
copper sample for which the system requests an invalidation under section
37(f)(2) of this rule.
(C) The
ninetieth percentile lead and copper concentrations:
(i) measured from among all lead and copper
tap samples collected during each monitoring period; and
(ii) calculated in accordance with section
36(c)(3) of this rule unless the commissioner calculates the system's ninetieth
percentile lead and copper levels under subsection (h).
(D) With the exception of initial tap
sampling conducted under section 37(d)(1) of this rule, the system shall:
(i) designate any site that was not sampled
during previous monitoring periods; and
(ii) include an explanation of why sampling
sites have changed.
(E)
The results of all tap samples for:
(i) pH;
and
(ii) where applicable:
(AA) alkalinity;
(BB) calcium;
(CC) conductivity;
(DD) temperature; and
(EE) orthophosphate or silica;
collected under section 38(c) through 38(f) of this rule.
(F) The results of all samples collected at
the entry point to the distribution system for applicable water quality
parameters under section 38(c) through 38(f) of this rule.
A water system shall report the results of all water quality parameter samples collected under section 38(c) through 38(f) of this rule during each six (6) month monitoring period specified in section 38(d) of this rule within the first ten (10) days following the end of the monitoring period unless the commissioner has specified a more frequent reporting requirement. For monitoring periods with a duration of 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 sections 36 and 37 of this rule.
(2) For an NTNCWS or a
CWS meeting the criteria of section 44(b)(7) of this rule that does not have
enough taps that can provide first-draw samples, the system shall do either of
the following:
(A) Provide written
documentation to the commissioner identifying standing times and locations for
enough nonfirst-draw samples to make up its sampling pool under section
37(b)(5) of this rule by the start of the first applicable monitoring period
under section 37(d) of this rule that commences after April 11, 2000, unless
the commissioner has waived prior approval of nonfirst-draw sample sites
selected by the system under section 37(b)(5) of this rule.
(B) If the commissioner has waived prior
approval of nonfirst-draw sample sites selected by the system, the system
shall:
(i) identify, in writing, each site
that did not meet the six (6) hour minimum standing time and the length of the
standing time for that particular substitute sample collected under section
37(b)(5) of this rule; and
(ii)
include the information under item (i) with the lead and copper tap sample
results required to be submitted under subdivision (1)(A).
(3) At a time specified by the
commissioner or, if no specific time is designated by the commissioner, as
early as possible prior to the addition of a new source or any long-term change
in water treatment, the following apply:

subject to reduced monitoring under section 37(d)(4) of this rule.
(iii) A water system subject to a monitoring
waiver under section 37(g) of this rule.
(B) The commissioner, before the
implementation by the water system, shall review and approve the addition of
the following:
(i) A new source.
(ii) Long-term change in treatment. Examples
of long-term treatment changes include the following:
(AA) The addition of a new treatment process
or modification of an existing treatment process.
(BB) Switching secondary
disinfectants.
(CC) Switching
coagulants, for example, alum to ferric chloride.
(DD) Switching corrosion inhibitor products,
for example, orthophosphate to blended phosphate.
(EE) 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 do not include chemical dose fluctuations associated with daily raw water quality changes.
(4) Any
small system applying for a monitoring waiver under section 37(g) of this rule,
or subject to a waiver granted under section 37(g)(3) of this rule, shall
provide the following information to the commissioner in writing by the
specified deadline:

first applicable monitoring period in section 37(d) of this rule, any small
water system applying for a monitoring waiver shall provide the documentation
required to demonstrate that it meets the waiver criteria of section 37(g)(1)
and 37(g)(2) of this rule.
(B) Not
later than nine (9) years after the monitoring previously conducted under
section 37(g)(2) or 37(g)(4)(A) of this rule, each small system desiring to
maintain its monitoring waiver shall provide the information required by
section 37(g)(4)(A) and 37(g)(4)(B) of this rule.
(C) Not later than sixty (60) days after the
PWS becomes aware that it is no longer free of lead or copper containing
materials, or both, each small system with a monitoring waiver shall provide
written notification to the commissioner, setting forth the circumstances
resulting in the lead or copper containing materials, or both, being introduced
into the system and what corrective action, if any, the system plans to remove
these materials.
(D) By October 10,
2000, any small system with a waiver granted prior to April 11, 2000, and that
has not previously met the requirements of section 37(g)(1) of this rule shall
provide the information required by section 37(g)(1) of this rule.
