Utah Admin. Code R309-600-10 - Potential Contamination Source Inventory and Identification and Assessment of Controls
(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.
