Kan. Admin. Regs. § 28-45a-15 - Groundwater monitoring
(a) Each permittee
of an existing underground natural gas storage facility and each applicant for
a permit for a new underground natural gas storage facility shall submit a
groundwater monitoring plan with the permit application to the secretary for
review and consideration for approval to ensure the protection of public
health, safety, and the environment.
(b) Each permittee shall ensure that each
groundwater monitoring well meets the following requirements:
(1) Each permittee shall set the screen in
each shallow monitoring well at a depth that is inclusive of the seasonal
fluctuation of the water table.
(2) Each permittee shall ensure that all deep
groundwater monitoring wells extend a minimum of 25 feet into the bedrock, or
to a depth based on the geology and hydrogeology at the facility and approved
by the secretary.
(c)
Each well location and the spacing between all well locations shall be based on
the geology and the hydrogeology at the facility and approved by the secretary.
(d) Each permittee shall submit a
quality assurance plan, including techniques prescribed for sampling and
analysis, with the permit application to the secretary for review and
consideration for approval to ensure protection of public health, safety, and
the environment.
(e) Each
permittee shall collect groundwater samples and analyze the samples for
chlorides and any other parameter determined by the secretary to pose a threat
to public health, safety, and the environment. The reporting format shall be
determined by the secretary.
(f)
Each permittee shall submit the results for chloride analyses from groundwater
samples to the department on a quarterly basis.
(g) Each permittee shall monitor monthly for
the presence of combustible gas in the headspace in monitoring wells and shall
submit the results to the department on a quarterly basis.
(h) Each permittee shall submit a static
groundwater level measurement for each monitoring well with the quarterly
chloride results specified in subsection (f).
(i) Any permittee of an underground storage
facility where groundwater chloride concentrations exceed 250 milligrams per
liter may be required by the secretary to submit a work plan, for review and
consideration for approval, that describes methods to delineate any potential
source area and to control migration of the chloride contamination.
(j) Each permittee of a facility with any
detection of combustible gas shall submit a work plan that describes the
methods to eliminate any source areas and return the combustible gas levels to
levels that do not pose a risk to public health, safety, and the environment.
The plan shall be approved if the secretary determines that the plan is
protective of public health, safety, and the environment.
