When rules are adopted regarding temporary standards, they must conform with the requirements of 75-5-312. Standards must meet the following requirements: (a) for carcinogens, the water quality standard for protection of human health must be the value associated with an excess lifetime cancer risk level, assuming continuous lifetime exposure, not to exceed 1 x 10 -3 in the case of arsenic and 1 x 10 -5 for other carcinogens.

These criteria must be established in a manner that generally: (i) equates significance with the potential for harm to human health, a beneficial use, or the environment; (ii) considers both the quantity and the strength of the pollutant; (iii) considers the length of time the degradation will occur; (iv) considers the character of the pollutant so that greater significance is associated with carcinogens and toxins that bioaccumulate or biomagnify and lesser significance is associated with substances that are less harmful or less persistent. (d) provide that changes of nitrate as nitrogen in ground water are nonsignificant if the discharge will not cause degradation of surface water and the predicted concentration of nitrate as nitrogen at the boundary of the ground water mixing zone does not exceed: (i) 7.5 milligrams per liter from sources other than sewage; (ii) 5.0 milligrams per liter from sewage discharged from a system that does not use level two treatment in an area where the ground water nitrate as nitrogen is 5.0 milligrams per liter or less; (iii) 7.5 milligrams per liter from sewage discharged from a system using level two treatment, which must be defined in the rules; or **** 69th Legislature 2025 HB 685 - 14 - Authorized Print Version – HB 685 ENROLLED BILL (iv) 7.5 milligrams per liter from sewage discharged from a system in areas where the ground water nitrate as nitrogen level exceeds 5.0 milligrams per liter primarily from sources other than human waste; and (e) for septic system discharges that are not subject to ground water permitting requirements under 75-5-401, establish criteria to determine when the discharges result in nonsignificant changes in surface water quality in order that those discharges are not required to undergo review under 75-5-303(3) and no further analysis under law or rule is required. The criteria must: (i) be adopted by rule before July 1, 2024; and (ii) be developed in a manner that generally considers soil type, mixing zone dilution and nitrogen credits, horizontal distance between the discharge and the surface water in the direction of ground water flow, and elevation, including: (A) adopt surface water impacts for low flow conditions based on mixing zone dilution concentrations and other credits for nitrogen; (B) credit nitrogen degradation at the drainfield and riparian zone attenuation based on soil type; (C) exempt surface water body impacts when drainfield is lower in elevation than the waterbody; (D) limit the adjacent to surface water trigger analysis to a maximum of 1/4 or 1/2 mile from the drainfield to a surface water, depending on soil type; and (E) create nonsignificant surface water impact categories of 500 or more feet from the surface water that consider soil texture, ground water depths and other pertinent information. (6) to the extent practicable, ensure that the rules adopted under subsection (5) establish objective and quantifiable criteria for various parameters.

If the department rejects a petition under this subsection (3)(b), it shall specify in writing the reasons for the rejection and the petition's deficiencies. (c) The department may not adopt a rule classifying state waters as outstanding resource waters until it accepts a petition and makes a written finding containing the provisions enumerated in subsection (3)(d) that, based on a preponderance of the evidence: (i) the waters identified in the petition constitute an outstanding resource based on the criteria **** 69th Legislature 2025 HB 685 - 17 - Authorized Print Version – HB 685 ENROLLED BILL provided in subsection (4); (ii) the increased protection under the classification is necessary to protect the outstanding resource identified under subsection (3)(a) because of a finding that the outstanding resource is at risk of having one or more of the criteria provided in subsection (4) compromised as a result of pollution; and (iii) classification as an outstanding resource water is necessary because of a finding that there is no other effective process available that will achieve the necessary protection. (d) The written finding provided for in subsection (3)(c) must: (i) identify the criteria provided in subsection (4) that serve as justification for the determination that the water is an outstanding resource; (ii) specifically identify the criteria that are at risk and explain why those criteria are at risk; and (iii) specifically explain why other available processes, including the requirements of 75-5-303, will not achieve the necessary protection. (4) The department shall consider the following criteria in determining whether certain state waters are outstanding resource waters. However, the department may determine that compliance with one or more of these criteria is insufficient to warrant classification of the water as an outstanding resource water. The department shall consider: (a) whether the waters have been designated as wild and scenic; (b) the presence of endangered or threatened species in the waters; (c) the presence of an outstanding recreational fishery in the waters; (d) whether the waters provide the only source of suitable water for a municipality or industry; (e) whether the waters provide the only source of suitable water for domestic water supply; and (f) other factors that indicate outstanding environmental or economic values not specifically mentioned in this subsection (4). (5) Before accepting a petition, the department shall: (a) publish a notice and brief description of the petition in a daily newspaper of general circulation in the area affected and make copies of the proposal available to the public. The cost of publication must be paid by the petitioner.

(6) (a) After acceptance of a petition, the department shall prepare an environmental impact statement, as provided under Title 75, chapter 1, part 2, and this section. (b) (i) The petitioner is responsible for all of the costs associated with gathering and compiling data and information, and completing the environmental impact statement. (ii) Before the department may initiate work on the environmental impact statement, the petitioner shall pay the estimated cost of completing the environmental impact statement, as determined by the department. (iii) Upon completion of the environmental impact statement, the petitioner shall pay the department any costs that exceeded the estimated cost. If the cost of the environmental impact statement was less than the estimated cost paid by the petitioner, the department shall reimburse the difference to the petitioner. (iv) The department may not grant or deny a petition until full payment for the environmental impact statement is received. (7) The department shall consult with other relevant state agencies and county governments when reviewing outstanding resource water classification petitions. (8) (a) After completion of an environmental impact statement and consultation with state agencies and local governments, the department may deny an accepted outstanding resource water classification petition if it finds that: **** 69th Legislature 2025 HB 685 - 19 - Authorized Print Version – HB 685 ENROLLED BILL (i) the requirements of subsection (3)(c) have not been met; or (ii) based on information available to the department from the environmental impact statement or otherwise, approving the outstanding resource waters classification petition would cause significant adverse environmental, social, or economic impacts. (b) If the department denies the petition, it shall identify its reasons for petition denial. (c) If the department grants the petition, the department shall initiate rulemaking to classify the waters as outstanding resource waters. (9) A rule classifying state waters as outstanding resource waters under this section may be adopted but is not effective until approved by the legislature. (10) The department may not postpone or deny an application for an authorization to degrade state waters a feasibility allowance under 75-5-303 based on pending: (a) department action on an outstanding resource water classification petition regarding those waters; or (b) legislative approval of department action designating those waters as outstanding resource waters. (11) As used in this section, "petitioner" means an individual, corporation, partnership, firm, association, or other private or public entity that petitions the department to adopt rules to classify waters as outstanding resource waters."
