Utah Admin. Code R309-600-10
(1) Prioritized Inventory of Potential Contamination Sources - Each PWS shall list every potential contamination source within each DWSP zone or management area in priority order and state the basis for this order. This priority ranking shall be according to relative risk to the drinking water source. The name and address of each commercial and industrial potential contamination source is required. Additional information should include the name and phone number of a contact person and a list of the chemical, biological, and radiological hazards associated with each potential contamination source. Additionally, each PWS shall identify each potential contamination source as to its location in zones one, two, three, four or in a management area and plot it on the map required in Subsection R309-600-9(6)(a)(viii) or Subsection R309-600-9(6)(b)(i).
(2) Identification and Assessment of Current Controls - PWSs are not required to plan and implement land management strategies for potential contamination source hazards that are assessed as "adequately controlled." If controls are not identified, the potential contamination source will be "not adequately controlled." Additionally, if the hazards at a potential contamination source cannot be identified, the potential contamination source must be assessed as "not adequately controlled." Identification and assessment should be limited to one of the following controls for each applicable hazard: regulatory, best management and pollution prevention, physical, or negligible quantity. Each of the following topics for a control must be addressed before identification and assessment will be considered complete. Refer to the "Source Protection User's Guide for Groundwater Sources" for a list of government agencies and the programs they administer to control potential contamination sources. This guide may be obtained from DDW.
(b) Best Management and Pollution Prevention Practice Controls - List the specific best management and pollution prevention practices which have been implemented by potential contamination source management to control the hazard and
show that they are willing to continue the use of these practices; explain how these practices prevent groundwater contamination; assess the hazard; and set a date to reassess the hazard.
(3) For meeting the requirements of Rule R309-600, the Director will consider a PWS's assessment that a potential contamination source which is covered by a permit or approval under one of the regulatory programs listed below sufficient to demonstrate that the source is adequately controlled unless otherwise determined by the Director. For any other state programs, the PWS's assessment is subject to review by the Director; as a result, a PWS's DWSP Plan may be disapproved if the Director does not concur with its assessment.
