Regulation of Underground Injection Control Wells
Summary
The bill grants the energy and carbon management commission (commission) authority over class I, class IV, and class V injection wells and allows the commission to seek and adopt rules related to primacy from the United States environmental protection agency (EPA) for these classes of injection wells. The rules adopted by the commission may only be more stringent than corresponding federal requirements if certain findings are made at a public hearing. The commission may assess and collect fees related to the regulation of class I, class IV, and class V injection wells. A person that willfully violates a rule, permit, authorization, or order of the commission related to these classes of injection wells commits a misdemeanor and is subject to certain penalties. The executive director of the department of resources (executive director) is required to propose initial spending authority in the amount necessary to enforce rules for the permitting, authorization, and regulation of class I, class IV, and class V injection wells. The office of state planning and budgeting (OSPB) is also required to submit a proposal to eliminate or minimize the impact of associated fee revenue for the first state fiscal year that the fee revenue is assessed on the state fiscal year spending limitation in the state constitution. The bill also grants the mined land reclamation board (board) authority over class III injection wells and allows the board to seek and adopt rules related to primacy from the EPA for class III injection wells. The board may assess and collect fees related to the regulation of class III injection wells. The rules adopted by the board may only be more stringent than corresponding federal requirements if certain findings are made at a public hearing. A person that violates a rule, permit, authorization, or order of the board related to class III injection wells or that operates a class III injection well without a permit from the board is subject to certain penalties. The bill also provides that a class III injection well is not eligible for an exemption from designated mining operation status, which status subjects the operator to certain rules adopted by the board. The executive director is required to propose initial spending authority in the amount necessary to enforce rules for the permitting, authorization, and regulation of class III injection wells. OSPB is also required to submit a proposal to eliminate or minimize the impact of associated fee revenue for the first state fiscal year that the fee revenue is assessed on the state fiscal year spending limitation in the state constitution.(Note: Italicized words indicate new material added to the original summary; dashes through words indicate deletions from the original summary.)(Note: This summary applies to the reengrossed version of this bill as introduced in the second house.)
