department may charge a reasonable fee for the data, commensurate with its cost of providing the data to the
requestor.
(6) By October 1, 1999, and in consultation with the statewide TMDL advisory group, the
department shall use the data management system developed and maintained pursuant to subsection (5) to

department removes a water body because there is a lack of sufficient credible data to support its listing, the
department shall monitor and assess that water body during the next field season or as soon as possible
thereafter to determine whether it is a threatened water body or an impaired water body.

(g) the size of the water body not achieving standards;
(h) immediate programmatic needs, such as waste load allocations for new permits or permit
renewals and load allocations for new nonpoint sources;
(i) court orders and decisions relating to water quality;
(j) state policies and priorities, including the protection and restoration of native fish when

water body are currently in place; and
(m) the recreational, economic, and aesthetic importance of a particular water body.
(8) Except as provided in subsection (9), the department shall, in consultation with the statewide
TMDL advisory group, develop a method of rating water bodies according to the criteria and considerations

without first validating the data necessary to support the ranking.
(9) (a) When the department receives an application for a new individual permit to discharge into a
surface water body or a segment of a surface water body pursuant to 75-5-401, the surface water body or
segment of a surface water body has been listed pursuant to subsection (2) of this section, the discharge would

writing to a timeframe in which the department shall complete development of the TMDL. If the department
specifies a lack of resources as a reason why the department cannot complete development of the TMDL in
accordance with subsection (9)(a)(ii), the department shall clearly explain in its written specification what
resources are not available, why those resources are not available, and when those resources will be available.
(c) If the department and the applicant cannot mutually agree to a timeframe in accordance with
