(F) A public water system shall maintain records relating
to lead and copper requirements under §290.117 of this title
(relating to Regulation of Lead and Copper) for no less than 12 years.
Any system subject to the requirements of §290.117 of this title
shall retain on its premises original records of all sampling data
and analyses, reports, surveys, letters, evaluations, schedules, executive
determinations, and any other information required by the executive
director under §290.117 of this title. These records include,
but are not limited to, the following items: tap water monitoring
results including the location of each site and date of collection;
certification of the volume and validity of first-draw-tap sample
criteria via a copy of the laboratory analysis request form; where
residents collected the sample; certification that the water system
informed the resident of proper sampling procedures; the analytical
results for lead and copper concentrations at each tap sample site;
and designation of any substitute site not used in previous monitoring
periods.
(G) A public water system shall maintain records relating
to special studies and pilot projects, special monitoring, and other
system-specific matters as directed by the executive director.
(4) Public water systems shall submit routine reports
and any additional documentation that the executive director may require
to determine compliance with the requirements of this chapter.
(A) The reports must be submitted to the Texas Commission
on Environmental Quality, Water Supply Division, MC 155, P.O. Box
13087, Austin, Texas 78711-3087 by the tenth day of the month following
the end of the reporting period.
(B) The reports must contain all the information required
by the drinking water standards and the results of any special monitoring
tests which have been required.
(C) The reports must be completed in ink, typed, or
computer-printed and must be signed by the licensed water works operator.
(5) All public water systems that are affected utilities
under TWC §13.1394 or §13.1395 must maintain the following
records for as long as they are applicable to the system:
(A) An emergency preparedness plan approved by the
executive director and a copy of the approval letter.
(B) All required operating, inspection, testing, and
maintenance records for auxiliary power equipment, and associated
components required to be maintained, or actions performed as prescribed
in §290.46(m)(8) of this title.
(C) Copies of the manufacturer's specifications for
all generators that are part of the approved emergency preparedness
plan.
(g) Disinfection of new or repaired facilities. Disinfection
by or under the direction of water system personnel must be performed
when repairs are made to existing facilities and before new facilities
are placed into service. Disinfection must be performed in accordance
with American Water Works Association (AWWA) requirements and water
samples must be submitted to an accredited laboratory. The sample
results must indicate that the facility is free of microbiological
contamination before it is placed into service. When it is necessary
to return repaired mains to service as rapidly as possible, doses
may be increased to 500 mg/L and the contact time reduced to 1/2 hour.
(h) Calcium hypochlorite. A supply of calcium hypochlorite
disinfectant shall be kept on hand for use when making repairs, setting
meters, and disinfecting new mains prior to placing them in service.
(i) Plumbing ordinance. Public water systems must adopt
an adequate plumbing ordinance, regulations, or service agreement
with provisions for proper enforcement to ensure that neither cross-connections
nor other unacceptable plumbing practices are permitted (See §290.47(b)
of this title (relating to Appendices)). Should sanitary control of
the distribution system not reside with the purveyor, the entity retaining
sanitary control shall be responsible for establishing and enforcing
adequate regulations in this regard. The use of pipes and pipe fittings
that contain more than 0.25% lead or solders and flux that contain
more than 0.2% lead is prohibited for installation or repair of any
public water supply and for installation or repair of any plumbing
in a residential or nonresidential facility providing water for human
consumption and connected to a public drinking water supply system.
This requirement may be waived for lead joints that are necessary
for repairs to cast iron pipe.
(j) Customer service inspections. A customer service
inspection certificate shall be completed prior to providing continuous
water service to new construction, on any existing service either
when the water purveyor has reason to believe that cross-connections
or other potential contaminant hazards exist, or after any material
improvement, correction, or addition to the private water distribution
facilities. Any customer service inspection certificate form which
varies from the format found in commission Form 20699 must be approved
by the executive Cont'd... |
