Universal Citation: UT Admin Code R 309-600-10

Current through Bulletin 2024-18, September 15, 2024

(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).

(a) List of Potential Contamination Sources - A List of Potential Contamination Sources is found in the "Source Protection User's Guide for Groundwater Sources." This document may be obtained from DDW. This list may be used by PWSs as a guide to inventorying potential contamination sources within their DWSP zones and management areas.

(b) Refining, Expanding, Updating, and Verifying Potential Contamination Sources - Each PWS shall update its list of potential contamination sources to show current conditions within DWSP zones or management areas. This includes adding potential contamination sources which have moved into DWSP zones or management areas, deleting potential contamination sources which have moved out, improving available data about potential contamination sources, and any other appropriate refinements.

(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.

(a) Regulatory Controls - Identify the enforcement agency and verify that the hazard is being regulated by them; cite and quote applicable references in the regulation, rule or ordinance which pertain to controlling the hazard; explain how the regulatory control prevents groundwater contamination; assess the hazard; and set a date to reassess the hazard.

(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.

(c) Physical Controls - Describe the physical controls which have been constructed to control the hazard; explain how these controls prevent contamination; assess the hazard; and set a date to reassess the hazard.

(d) Negligible Quantity Control - Identify the quantity of the hazard that is being used, disposed, stored, manufactured, or transported; explain why this amount should be considered a negligible quantity; 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.

(a) The Utah Groundwater Quality Protection program established by Section 19-5-104 and Rule R317-6;

(b) closure plans or Part B permits under authority of the Resource Conservation and Recovery Act (RCRA) of 1984 regarding the monitoring and treatment of groundwater;

(c) the Utah Pollutant Discharge Elimination System (UPDES) established by Section 19-5-104 and Rule R317-8;

(d) the Underground Storage Tank Program established by Section 19-6-403 and Rules R311-200 through R311-208; and

(e) the Underground Injection Control (UIC) Program for classes I-IV established by Sections 19-5-104 and 40-6-5 and Rules R317-7 and R649-5.
