| (C) The executive director may allow the use of previously
collected monitoring data for purposes of monitoring, if the data
were collected and analyzed in accordance with the requirements of
this section and 40 CFR Part 141, Subpart I.
(i) Reporting. Systems shall report any information
required by this section and 40 CFR Part 141, Subpart I to the executive
director.
(1) Reporting lead and copper tap sample results. Tap
sample results shall be reported within ten days following the end
of each monitoring period as specified by the executive director.
For systems on annual or less frequent schedules, the end of the monitoring
period is September 30 of the calendar year in which the sampling
occurs, or if the executive director has established an alternate
monitoring period, the last day of that period.
(A) A system shall provide documentation for each tap
water lead or copper sample for which the water system requests invalidation.
(B) The system shall provide the following information
to the executive director:
(i) the results of all tap samples for lead and copper
including the location of each site and the criteria under which the
site was selected for the system's sampling pool; and
(ii) an identification of sampling sites utilized during
the current monitoring period that were not sampled during previous
monitoring periods, and an explanation why sampling sites have changed.
(2) Reporting entry point lead and copper sample results.
A water system shall report the sampling results for all source water
samples collected in accordance with subsection (e) of this section
within the first 10 days following the end of each source water monitoring
period.
(3) Reporting WQP results. Systems must report all
results of WQP analyses including the location/address of each distribution
system sampling point. This report must include each WQP specified
in subsection (e) of this section, as well as all sample results from
entry points to the distribution system. WQP reports should be submitted
to the executive director within the first ten days following the
end of each applicable monitoring period. For monitoring periods with
a duration less than six months, the end of the monitoring period
is the last date samples can be collected during that period.
(A) Systems shall report the results of all distribution
samples for pH, and where applicable, alkalinity, calcium, conductivity,
temperature, and orthophosphate or silica.
(B) Systems shall report the results of all samples
collected at the entry point(s) to the distribution system for applicable
water quality parameters.
(C) A system using only groundwater that is allowed
to limit WQP monitoring to a subset of entry points shall report,
by the commencement of such monitoring, written correspondence to
the executive director that identifies the sources flowing to each
of the system's entry points and report information sufficient to
demonstrate that the sites are representative of water quality and
treatment conditions throughout the system.
(4) Reporting distribution material and sample site
data. New systems shall submit the first material survey by December
31 of the year in which they are assigned a Public Water System Identification
Number. The executive director may allow a system to submit the first
material survey by December 31 of the year in which the system's status
becomes active.
(A) All systems shall submit Materials Survey and Site
Selection Forms (TCEQ Form Number 20467) describing the entire system
before performing tap sampling.
(B) Any system seeking reduced nine-year tap sampling
under subsection (c)(2)(D) of this section shall submit current documentation
showing that there are no lead- or copper-containing materials within
the distribution system.
(i) Prior to starting reduced nine-year tap sampling,
a system shall submit documentation showing that there are no lead-
or copper- containing materials within the distribution system and
that the system complies with all drinking water standards of this
subchapter.
(ii) No later than nine years after the first nine-year
tap samples are collected, any system desiring to remain on reduced
nine-year tap sampling shall provide updated documentation showing
that there are no lead- or copper- containing materials within the
distribution system and that the system complies with all drinking
water standards of this subchapter.
(iii) No later than 60 days after detecting lead-containing
and/or copper-containing material, as appropriate, each system with
a reduced nine-year tap sampling schedule shall provide written notification
to the executive director, setting forth the circumstances resulting
in the lead-containing or copper-containing materials being introduced
into the system and what corrective action, if any, the system plans
to remove these materials.
(C) Water systems requesting a change to previously
approved sample sites shall report supporting information, including
an explanation as to why a sampling site was changed from the previous
round of sampling, if applicable. If a water system changes a sampling
site for any reason allowed in this section, the water system must
provide the executive director with a written explanation showing
which sampling site will be abandoned and the sampling site that replaces
the abandoned sampling site.
(5) Reporting public education. A system that is required
to perform public education must provide copies of public education
materials and certification that distribution of said materials is
being conducted in accordance with this subsection to the executive
director within ten days after the delivery of the materials to the
public.
(6) Reporting consumer notification. No later than
three months following the end of the monitoring period, each system
must mail a sample copy of the consumer notification of tap results
to the executive director along with a certification that the notification
has been distributed in a manner consistent with the requirements
of subsection (j) of this section.
(7) Corrosion control reporting. Systems that are required
to perform corrosion control studies and install corrosion control
treatment shall report all information required under subsection (f)
of this section. Corrosion control treatment data shall be reported
as required by the executive director. Systems shall report the following
information listed in this paragraph.
(A) Systems demonstrating that they have already optimized
corrosion control, must provide all information required in subsection
(f) of this section.
(B) Systems that are recommending optimal corrosion
control treatment must provide all supporting documentation for their
recommendation regarding optimal corrosion control treatment under
40 CFR §141.82(a).
(C) Systems that are required to evaluate the effectiveness
of corrosion control treatments under subsection (f) of this section,
must submit the information required by that section.
(D) Systems required to install optimal corrosion control
designated by the executive director under 40 CFR §141.82(d),
must submit a letter certifying that the system has completed installing
that treatment.
(8) Reporting source treatment. A system that is required
to install source water lead or copper removal treatment must certify
in writing that the system has completed installing the approved treatment
within 24 months after the executive director approved that treatment.
(9) Reporting system conditions and facility changes.
Systems must report changes of system conditions and facilities that
may impact corrosion to the executive director.
(A) The water system must inform the executive director
of the identity of treated and non-treated entry points and their
seasonal use, if any, and demonstrate that the WQPs represent water
quality and treatment conditions throughout the system.
(B) At a time specified by the executive director,
or if no specific time is designated by the executive director, 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 or subject to reduced tap sampling shall
submit written documentation to the executive director describing
the change or addition. The water system may not implement the addition
of a new source or long-term change in treatment until notified in
writing that the change is approved by the executive director. 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 Cont'd... |
