Section 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.
