(a) Notwithstanding the requirements of § 144.31(c)(1) of this chapter, the owner or operator of an existing Class I or III well shall submit a complete permit application no later than 90 days after the effective date of the program. (b) The topographic map (or other map if a topographic map is unavailable) required by § 144.31(e)(7) of this chapter, shall extend two miles from Class II wells, and 21⁄2 miles from Class I and III wells. These maps will show all the information listed in paragraph 144.31(e)(7) within 1⁄2 mile for Class II wells and 21⁄2 miles for Class I and III wells. § 147.3008 Criteria for aquifer exemptions. The aquifer exemption criterion in § 146.4(c) of this chapter shall not be available for this program. § 147.3009 Area of review. The area of review shall be defined as follows: (a) Class II wells. The area of review for Class II permits and area permits shall be defined by a fixed radius as described in § 146.6(b) (1) and (2) of this chapter except that the radius shall be one-half mile. (b) Class I and III wells. The area of review for Class I and III wells are well fields which may be either: (1) An area defined by a radius two and one-half miles from the well or well field; or (2) An area one-quarter mile from the well or well field where the well field production at the times exceeds injection to produce a net withdrawal; or (3) A suitable distance, not less than one-quarter mile, proposed by the owner or operator and approved by the Director based upon a mathematical calculation such as that found in § 146.6(a)(2) of this chapter. 88 147.3010 Mechanical integrity tests. The monitoring of annulus pressure listed in 146.8(b)(1) of this chapter will only be acceptable if preceded by a pressure test, using liquid or gas that clearly demonstrates that mechanical integrity exists at the time of the pressure test. § 147.3011 Plugging and abandonment of Class III wells. To meet the requirements of paragraph 146.10 (d) of this chapter, owners and operators of Class III uranium projects underlying or in aquifers containing up to 5,000 mg/l TDS which have been exempted under § 146.4 of this chapter shall: (a) Include in the required plugging and abandonment plan a plan for aquifer clean-up and monitoring which demonstrates adequate protection of surrounding USDWs. (1) The Director shall include in each such permit for a Class III uranium project the concentrations of contaminants to which aquifers must be cleaned up in order to protect surrounding USDWS. (2) The concentrations will be set as close as is feasible to the original conditions. (b) When requesting permission to plug a well, owners and operators shall submit for the Director's approval a schedule for the proposed aquifer cleanup, in addition to the information required by § 146.34(c). (c) Cleanup and monitoring shall be continued until the owner or operator certifies that no constituent listed in the permit exceeds the concentrations required by the permit, and the Director notifies the permittee in writing that cleanup activity may be terminated. § 147.3012 Construction requirements for Class I wells. In addition to the cementing requirement of § 146.12(b) of this chapter, owners and operators of Class I wells shall, through circulation, cement all casing to the surface. (a) In addition to the information listed in § 146.14(a) of this chapter, the Director shall consider the following prior to issuing any Class I permit: (1) Expected pressure changes, native fluid displacement, and direction of movement of the injected fluid; and (2) Methods to be used for sampling, and for measurement and calculation of flow. (b) In addition to the information listed in § 146.14(b) of this chapter, the Director shall consider any information required under § 146.14(a) of this chapter (as supplemented by this subpart) that has been gathered during construction. § 147.3014 Construction requirements for Class III wells. (a) In addition to the requirements of § 146.32(c)(3) of this chapter, radiological characteristics of the formation fluids shall be provided to the Director. (b) In addition to the requirements of § 146.32(e) of this chapter, the Director may require monitoring wells to be completed into USDWs below the injection zone if those USDWS may be affected by mining operations. § 147.3015 Information to be considered for Class III wells. (a) In addition to the requirements of § 146.34(a) of this chapter, the following information shall be considered by the Director: (1) Proposed construction procedures, including a cementing and casing program, logging procedures, deviation checks, and a drilling, testing and coring program. (2) Depth to the proposed injection zone, and a chemical, physical and ra diological analysis of the ground water in the proposed injection zone sufficient to define pre-injection water quality as required for aquifer cleanup by § 147.3011 of this subpart. (3) An aquifer cleanup plan if required by § 147.3003(b) of this subpart. (4) Any additional information that may be necessary to demonstrate that cleanup will reduce the level of contaminants in the surrounding USDWs as close as feasible to the original conditions. (b) In addition to the requirements of § 146.34(b) of this chapter, the Director shall consider any information required under § 146.34(a) of this chapter (as supplemented by this subpart) that has been gathered during construction. § 147.3016 Criteria and standards applicable to Class V wells. In addition to the criteria and standards applicable to Class V wells set forth in Subpart F of Part 146 of this chapter, owners and operators of wells that do not fall within the Class IV category but that are used to dispose of radioactive wastes (as defined in 10 CFR Part 20, Appendix B, Table II, Column 2, but not including high level and transuranic wastes and spent nuclear fuel covered by 40 CFR Part 191) shall comply with all of the requirements applicable to Class I injection wells in 40 CFR Parts 124, 144 and 146 as supplemented by this subpart. Appendix A to Subpart HHHExempted Aquifers in New Mexico The areas described by a one-quarter mile radius around the following Class II wells in the listed formations are exempted for the purpose of Class II injection. |
