1. A. Existing and new Class V injection wells are authorized by rule, subject to the conditions in Section 7-6.5 of these rules.
2. B. Well authorization under this Section 7-6.3 expires upon the effective date of a permit issued in accordance with these rules or upon proper closure of the well.

3. C. An owner or operator of a well which is authorized by rule under this Section 7-6.3 is prohibited from injecting into the well:

   1. 1. Upon the effective date of a permit denial.
   2. 2. Upon failure to submit a permit application in a timely manner if requested by the Director under Section 7-6.4 of these rules.

   3. 3. Upon failure to submit inventory information in a timely manner in accordance with Section 7-6.4(C) of these rules.

      6.4

4. A. The Director may require any owner or operator of a Class I, III or V well authorized under Section 7-6.3 to apply for and obtain an individual or area permit. Cases where permits may be required include:

   1. 1. The injection well is not in compliance with the applicable rules.
   2. 2. The injection well is not or no longer is within the category of wells and types of well operations authorized by Section 7-6.3.
   3. 3. Protection of an USDW.
5. B. Any owner or operator authorized under Section 7-6.3 may request a permit and hence be excluded from coverage under Section 7-6.3.

6. C. Owners or operators of all injection wells regulated by Section 7-6.3 shall submit the following inventory information to the Director:

   1. 1. facility name and location;
   2. 2. name and address of legal contact;
   3. 3. ownership of facility;
   4. 4. nature and type of injection wells; and

   5. 5. operating status of injection wells.

      Inventory information shall be submitted no later than January 19, 1984 for existing injection wells and before injection begins for new injection wells.

      6.5 Additional requirements for large-capacity cesspools and motor vehicle waste disposal wells (see Class V well descriptions in Sections 7-3.5(B) and 7-3.5(O), respectively).

7. A. All existing large-capacity cesspools (operational or under construction by April 5, 2000) must close by April 5, 2005. See closure requirements in Section 7-6.6.
8. B. All new or converted large-capacity cesspools (construction not started before April 5, 2000) are prohibited.

9. C. All existing motor vehicle waste disposal wells (operational or under construction by April 5, 2000) must either be closed or their owners or operators must obtain a UIC permit.

   1. 1. For those wells located within a ground water protection area as designated by the Utah Division of Drinking Water (DDW), closure or permit application submittal must take place within one year of completion of DDW's ground water protection area assessment for the pertinent area.
   2. 2. All motor vehicle waste disposal wells statewide located outside a ground water protection area must either be closed or their owners or operators must submit a UIC permit application by January 1, 2007.
   3. 3. If well closure is the option chosen, the closure requirements in Section 7-6.6 must be followed. The closure deadline may be extended by the Director for up to one year under certain conditions, such as intent to connect to a sanitary sewer.
   4. 4. If obtaining a UIC permit is the option chosen, Utah Drinking Water Maximum Contaminant Levels (MCL's), Utah Ground Water Quality Standards, and EPA Adult Lifetime Health Advisories must be met at the point of injection while the permit application is under review. These standards must also be met at the point of injection under the terms of the permit, when issued. Utah Ground Water Protection Levels may be required to be met at downgradient ground water monitoring wells, if required to be installed. Such a permit may require pretreatment of the wastewater, and will require adherence to best management practices and monitoring of the quality of the injectate and any sludge generated.

10. D. All new or converted motor vehicle waste disposal wells (construction not started before April 5, 2000) are prohibited.

    6.6 Class V well plugging and abandonment requirements.

11. A. Prior to abandoning a Class V well, the owner or operator shall close the well in a manner that prevents the movement of fluid containing any contaminant into an underground source of drinking water, if the presence of that contaminant may cause a violation of any primary drinking water regulation under 40 CFR Part 141 or Utah Primary Drinking Water Standards R309-200-5, or may otherwise adversely affect the health of persons.
12. B. The owner or operator shall dispose of or otherwise manage any soil, gravel, sludge, liquids, or other materials removed from or adjacent to the well in accordance with all applicable Federal, State, and local regulations and requirements.

13. C. The owner or operator must notify the Director of intent to close the well at least 30 days prior to closure.

    6.7 Conversion of motor vehicle waste disposal wells. In limited cases, the Director may authorize the conversion (reclassification) of a motor vehicle waste disposal well to another type of Class V well. Motor vehicle wells may only be converted if: all motor vehicle fluids are segregated by physical barriers and are not allowed to enter the well; and, injection of motor vehicle waste is unlikely based on a facility's compliance history and records showing proper waste disposal. The use of a semi-permanent plug as the means to segregate waste is not sufficient to convert a motor vehicle waste disposal well to another type of Class V well.

    6.8 Time for Application for Permit. Any person who performs or proposes an underground injection for which a permit is or will be required shall submit a complete application to the Director in accordance with Section 7-9 a reasonable time before construction is expected to begin, except for new wells covered by an existing area permit.

    6.9 All applications for a Utah UIC permit, including any required Technical Report that addresses the technical requirements of R317-7-10 or R317-7-11, any technical information necessary for the adequate evaluation of any permit application, or any permit renewal applications and Technical Reports that are significantly different from the original permit application, must be prepared by or under the direction, and bear the seal, of a professional geologist or professional engineer.

6.1 The owner or operator of any new injection well is required to obtain a permit from the Director prior to construction unless excepted by R317-7-6.3. Compliance with construction plans and standards is required prior to commencing injection operations. Changes in construction plans require approval of the Director.

6.2 Owners or operators of existing underground injection wells are required to obtain a permit from the Director unless specifically excepted by Section 7-6.3 of these rules.
