This is not a legislative bill but a memorial (SCM 1004) from Arizona's state legislature, not a federal bill. It requests Congress to clarify the EPA's authority to regulate greenhouse gases like CO2 and methane, arguing the EPA lacks explicit statutory power under the Clean Air Act and that current regulations violate the "major questions doctrine" established by the Supreme Court in *West Virginia v. EPA* (2022). The memorial specifically asks Congress to end EPA "regulation overreach" by defining the agency's powers regarding greenhouse gas emissions. It directly affects federal environmental policy by challenging the EPA's current regulatory scope on climate-related emissions.
HB 2457 allows utilities to build new power plants colocated with large industrial energy users without needing environmental review, provided they give 30 days' written notice to the state commission and hold a public comment session in the affected county. The exemption applies only to public utilities (like municipal power entities) and requires the industrial user to already have all necessary zoning approvals. The state commission must define key terms like "colocated" (including distance or electrical connection details) and "large industrial energy user" (based solely on energy demand in megawatts, without favoring specific industries). This bill streamlines construction for certain projects while maintaining public input requirements.
HB 2494 creates special zoning districts for aggregate mining operations in Arizona counties. It requires county boards to establish these districts based on petitions from residents near existing operations and form committees with equal representation from mining operators and community members to set local rules. The bill exempts aggregate mining from standard zoning restrictions within designated districts while requiring operators to follow specific environmental and operational standards for dust, noise, and site reclamation. This directly affects counties establishing zoning districts and aggregate mining operators seeking to expand or operate within these areas.
HB 2641 prohibits local governments, fire departments, and state agencies from using class B firefighting foam containing intentionally added PFAS chemicals during training or testing, effective January 1, 2020. Exceptions allow emergency firefighting, fire prevention, and testing at facilities with proper containment, treatment, and disposal measures. The law specifically targets foam for flammable liquid fires (class B) but does not restrict manufacturing, sale, or emergency use of the foam. It defines PFAS chemicals as fluorinated substances used in firefighting formulations and clarifies that the prohibition applies only to non-emergency purposes.
HB 2428 clarifies jurisdiction over air pollution permits in Arizona, giving the state Department of Environmental Quality primary authority for major sources like power plants and refineries in counties without approved air plans. It allows counties to issue voluntary permits for emission reduction credits related to portable and mobile sources (like vehicles or temporary equipment). This affects local air agencies, businesses needing permits, and entities seeking to certify emission reductions under state law. The bill modifies existing permit procedures without changing pollution standards or creating new emission requirements.
HB 2078 updates Arizona's requirements for reclamation plans at aggregate mining sites. It requires mining operators to notify residential property owners within a half-mile of the operation about proposed reclamation plans, using prior public notices (like zoning applications) if published within that radius. The bill specifies that reclamation plans must include detailed measures for erosion control, revegetation, safety for hazardous areas, and post-mining land use. These changes apply to new reclamation plans submitted on or after September 15, 2024.
HB 2096 creates a program for Arizona counties to receive **forgivable financial assistance** from the Water Infrastructure Finance Authority to remediate cesspools posing risks to water quality, groundwater, or public health. It directly affects counties with high-risk cesspools, prioritizing projects in groundwater vulnerability zones, near surface waters, or in low-to-moderate income communities. Key provisions include: forgivable principal (no repayment required) for replacing cesspools with approved on-site systems or sewer connections, no voter approval needed for this assistance (unlike standard loans), and mandatory coordination with the Department of Environmental Quality. Counties must use funds exclusively for eliminating existing cesspools and cannot apply income-based eligibility to abandoned properties. The bill is proposed legislation (prefiled in 2025) and not yet enacted.
This bill outlines how specific environmental funds in Arizona can be used during the 2026-2027 fiscal year. It allows money from the underground storage tank fund to cover administrative costs and address sewage discharge problems in border areas like Naco. The legislation also permits the use of water banking and water protection funds to pay legal fees and cover departmental administrative expenses. Additionally, it sets a $15 million spending cap for the water quality assurance revolving fund and keeps vehicle emissions testing fees at their 2025 levels. Although the bill passed the legislature, it was vetoed by the Governor.
HCR 2057 is a concurrent resolution supporting geothermal energy development in Arizona. It calls for state agencies (including the Oil and Gas Conservation Commission, Department of Environmental Quality, and others) to create a standardized permitting process for next-generation geothermal projects. The resolution does not create new laws but urges agencies to align existing rules to make permitting more predictable for developers. It directly affects geothermal energy companies and Arizona's regulatory agencies by promoting streamlined project approvals. The resolution passed the House and is now moving to the Senate.
HCR 2020 is a non-binding legislative resolution expressing support for for-sale housing developments outside designated water service areas, provided they enroll in the Central Arizona Groundwater Replenishment District (CAGRD) and replenish groundwater as required by Arizona's water rules. It directly affects new housing projects in Phoenix, Pinal, and Tucson active management areas by requiring groundwater replenishment to offset usage. The resolution highlights that CAGRD has enabled over 400,000 homes to be built without impacting groundwater tables since 1995, aligning with existing state water management requirements.
