Local ordinances: administrative fines or penalties.

Existing law authorizes the legislative body of a local agency, as defined, to, by ordinance, make any violation of an ordinance subject to an administrative fine or penalty. Existing law requires a local agency to set forth, by ordinance, the administrative procedures that govern the imposition, enforcement, collection, and administrative review of those administrative fines or penalties, as specified. This bill would, for specified administrative fines or penalties, authorize a local agency to, subject to specified requirements, file a certified copy of a final administrative order or decision that directs payment of the administrative fine or penalty with the clerk of the superior court of any county, as specified, and require the clerk to enter judgment immediately in conformity with the decision or order. The bill would also authorize a local agency to, by ordinance, establish a procedure to collect administrative fines or penalties by lien upon the parcel of land on which the violation occurred if the ordinance meets specified requirements. The bill would specify that the remedies or penalties provided by these provisions are cumulative of the remedies or penalties available under any other law.

Planning and zoning: housing element: regional housing needs allocation.

(1) Existing law, the Planning and Zoning Law, requires each county and city to adopt a comprehensive, long-term general plan for the physical development of the county or city, which includes, among other mandatory elements, a housing element. Existing law requires a public agency to administer its programs and activities relating to housing and community development in a manner to affirmatively further fair housing, and take no action that is materially inconsistent with its obligation to affirmatively further fair housing. Existing law defines "affirmatively furthering fair housing," as provided. The Planning and Zoning Law requires that a housing element include, among other things, a program that sets forth a schedule of actions during the planning period. Existing law requires the Department of Housing and Community Development to develop a standardized reporting format for programs and actions taken pursuant to the requirement to affirmatively further fair housing. This bill would require the department to develop the above-described standardized reporting format on or before December 31, 2026. (2) Existing law requires, for the 4th and subsequent revisions of the housing element, the department to determine the existing and projected need for housing for each region, as specified. Existing law requires the department, in consultation with the council of governments, to determine the existing and projected need of housing for each region at least 2 years prior to the scheduled revision of the housing element, as provided. Existing law requires the department to meet and consult with the council of governments regarding the assumptions and methodology to be used to determine the region's housing needs at least 26 months prior to the scheduled revision of the housing element, as provided. This bill, except as specified, would extend the above-described timeline for the department to determine the existing and projected need of housing for each region from 2 years to 3 years prior to the scheduled revision of the housing element. The bill would require the department to meet and consult with the council of governments, as described above, pursuant to prescribed deadlines. For the 7th revision of the housing element, the bill would require the department to meet and consult with each council of governments at least 38 months prior to the scheduled revision, except for specified councils of governments. For the 8th and subsequent revision of the housing element, the bill would require the department to meet and consult with each council of governments at least 38 months prior to the scheduled revision. (3) Existing law authorizes at least 2 or more cities and a county, or counties, at least 28 months prior to the scheduled housing element revision, to form a subregional entity to allocate the subregion's existing and projected housing need among its members. If the council of governments does not receive a notification of this formation at least 28 months prior to the update, existing law requires the council of governments to implement specified requirements regarding the regional housing need process. Existing law requires the council of governments to determine the share of regional housing need assigned to each delegate subregion at least 25 months prior to the scheduled revision. This bill would extend the above-described timeline for cities and counties to form a subregional entity to allocate the subregion's housing need, as provided, from 28 months to 34 months, and the above-described timeline for the council of governments to determine the share of regional housing need assigned to each subregion from 25 months to 31 months, respectively. (4) Existing law, at least 2 years before a scheduled revision of the housing element, as specified, requires each council of governments, or delegate subregion as applicable, to develop, in consultation with the department, a proposed methodology for distributing the existing and projected regional housing need to jurisdictions, as specified. Existing law, at least 1 12 years before a scheduled revision of the housing element, as specified, requires each council of governments and delegate subregion, as applicable, to distribute a draft allocation of regional housing needs to each local government in the region or subregion, where applicable, and the department, as specified. This bill, except with respect to the 7th housing element cycle for councils of governments with a housing element revision due date during the 2027 calendar year, would instead require that the above-described methodology be developed from at least 2 12 years before a scheduled revision of the housing element, and that the distribution of the draft allocation plan be made at least 2 years before a scheduled revision of the housing element, respectively. (5) Existing law requires a planning agency to submit a copy of its draft housing element or amendments to its housing element or housing element revision to the department for review, and requires the department to notify the city, county, or city and county with written findings if the department finds that the housing element or the amendment does not substantially comply with specified law. If the department finds that the draft housing element or draft amendment is not in substantial compliance, existing law requires the jurisdiction to either update the draft to substantially comply with specified law, or adopt the draft housing element or amendment without changes, as provided. This bill would require the department, if the department finds that a draft element or draft amendment does not substantially comply, as described above, to (A) identify and explain the specific deficiencies in the draft element or draft amendment and (B) provide the specific analysis or text that the department expects the planning agency to include in the draft element or draft amendment to remedy those deficiencies, as specified. The bill would require a jurisdiction, in updating a noncompliant housing element or amendment under the above-described provisions, to include the specific analysis or text in its draft element or amendment. (6) This bill would incorporate additional changes to Section 65583 of the Government Code proposed by SB 340 and AB 610 to be operative only if this bill and either or both of those bills are enacted and this bill is enacted last. This bill would incorporate additional changes to Section 65584.01 of the Government Code proposed by SB 486 to be operative only if this bill and SB 486 are enacted and this bill is enacted last. This bill would incorporate additional changes to Section 65584.03 of the Government Code proposed by AB 1275 to be operative only if this bill and AB 1275 are enacted and this bill is enacted last. This bill would incorporate additional changes to Section 65584.04 of the Government Code proposed by SB 486 and AB 1275 to be operative only if this bill and either or both of those bills are enacted and this bill is enacted last. This bill would incorporate additional changes to Section 65585 of the Government Code proposed by AB 507 to be operative only if this bill and AB 507 are enacted and this bill is enacted last. (7) By imposing additional duties on local governments, this bill would create a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

Transit operators: paratransit: recertification of eligibility.

Under the Mills-Alquist-Deddeh Act, also known as the Transportation Development Act, revenues from a 14 percent sales tax in each county are, among other things, available for allocation by the transportation planning agency to transit operators and for community transit services. Existing law requires a transit operator that receives funds through the Mills-Alquist-Deddeh Act and that provides dial-a-ride or paratransit service to provide those services consistent with certain requirements. This bill would require, on or before January 1, 2027, transit operators, as defined, to establish a streamlined recertification process for eligible persons, as specified. The bill would require, on and after June 1, 2027, transit operators to only use the streamlined recertification process for eligible persons unless certain conditions apply. The bill would define "eligible persons" as persons who receive, or who are eligible to receive, paratransit services based on a disability and whose disability cannot reasonably be expected to improve over time, as determined by the person's qualified licensed medical professional, and whose ability to access the fixed route system cannot reasonably be expected to improve over time, as determined by the transit operator. To the extent the bill would impose additional duties on a local agency, it would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.

Livestock carcasses: disposal: composting.

Existing law prohibits a dead animal hauler or any other person from transporting a dead animal to any place, other than to certain specified facilities or destinations, unless a certain waiver is granted by the State Veterinarian, as specified. Existing law requires the Department of Resources Recycling and Recovery to adopt and revise minimum standards for solid waste handling, transfer, composting, transformation, and disposal, as prescribed. Pursuant to this authority, the department has adopted a regulation that prohibits the composting of unprocessed mammalian tissue except when received from certain sources. This bill would, notwithstanding those prohibitions, authorize any part of a livestock carcass resulting from a routine livestock mortality event or on-farm processing to be composted if certain requirements are met, including, among others, that the composting is conducted in accordance with best management practices for livestock composting adopted by the Secretary of Food and Agriculture, as specified.

This bill, the Musk Reduction Act, would expand that prohibition by adding musk ambrette, musk tibetene, musk moskene, and musk xylene to the list of banned ingredients. The bill would also, beginning January 1, 2027, prohibit the use of musk ketone in cosmetic products in excess of specified amounts, including 1.4% in fine fragrance products, and oral products, as defined. This bill would incorporate additional changes to Section 108980 of the Health and Safety Code proposed by Senate Bill 39 to be operative only if this bill and Senate Bill 39 are enacted and this bill is enacted last.

Environmental protection: 30x30 goals: land conservation: stewardship.

By Executive Order No. N-82-20, Governor Gavin Newsom directed the Natural Resources Agency to combat the biodiversity and climate crises by, among other things, establishing the California Biodiversity Collaborative and conserving at least 30% of the state's lands and coastal waters by 2030. Existing law provides that it is the goal of the state to conserve at least 30% of California's lands and coastal waters by 2030, known as the 30x30 goal. On April 22, 2022, the Natural Resources Agency issued the "Pathways to 30x30 California: Accelerating Conservation of California's Nature" report and existing law requires the Secretary of Natural Resources Agency to prepare and submit an annual report to the Legislature on progress made toward achieving the 30x30 goal, as provided. This bill would, to further specified findings of the Pathways to 30x30 Report, require the agency to develop strategies to reduce barriers and increase support for stewardship of conserved lands. The bill would require the agency to collaborate with stakeholders, California Native American tribes, and relevant state agencies to prepare a section on stewardship as part of the 2027 annual report on progress made toward achieving the 30x30 goal, which the bill would require to include, among other things, recommendations to increase and improve stewardship of 30x30 lands, including innovative ways to reduce barriers and increase federal, state, and local support for stewardship, as specified.

Geothermal powerplants and projects: certification and environmental review.

Existing law establishes and vests in the State Energy Resources Conservation and Development Commission (Energy Commission) various responsibilities with respect to developing and implementing the state's energy policies. Existing law authorizes persons proposing specified electrical generation, electrical transmission, hydrogen production, and energy storage projects to apply, on or before June 30, 2029, to the Energy Commission to certify sites and related facilities as environmental leadership development projects, as specified. Existing law makes a site and related facility certified by the Energy Commission subject to streamlining benefits related to CEQA with no further action by the applicant or the Governor. Under existing law, the Energy Commission's certification is in lieu of any permit, certificate, or similar document required by any governmental agency and supersedes any applicable statute, ordinance, or regulation, except as specified. This bill would expand the types of facilities eligible to be certified as environmental leadership development projects by the Energy Commission to include geothermal powerplants and projects that comprise multiple geothermal powerplants on a single site. This bill would incorporate additional changes to Section 25545 of the Public Resources Code proposed by SB 254 to be operative only if this bill and SB 254 are enacted and this bill is enacted last.

Firefighters: personal protective equipment.

The California Occupational Safety and Health Act of 1973 provides the Division of Occupational Safety and Health within the Department of Industrial Relations with the power, jurisdiction, and supervision over all employment and places of employment necessary to enforce and administer all occupational health and safety laws and to protect employees. The act grants to the Occupational Safety and Health Standards Board, an independent entity within the department, exclusive authority to adopt occupational safety and health standards within the state. Beginning July 1, 2018, and every 5 years thereafter, the act requires the board, in consultation with the department, to complete a comprehensive review of all revisions to National Fire Protection Association standards pertaining to certain personal protective equipment (PPE) and requires the board to consider modifying existing safety orders and to render a decision regarding the adoption of necessary changes to safety orders, or other applicable standards and regulations, no later than July 1 of the subsequent year, if the review finds that the revisions to applicable National Fire Protection Association standards provide a greater degree of personal protection than the safety orders. This bill would, in addition to the above-described requirement, require the board to consider modifying its existing safety order regarding firefighter personal protective equipment by January 1, 2028, to address National Fire Protection Association performance standards for PPE that are not relevant or applicable to how firefighters utilize their PPE and that result in the use of perfluoroalkyl and polyfluoroalkyl substances, fluoropolymers, flame retardants, and other hazardous substances in firefighting personal protective garments and auxiliary firefighting PPE, as provided. The bill would also require, by July 1, 2026, the Division of Occupational Safety and Health to report on progress toward implementation of the modified PPE safety standards, as provided. The bill would also make related findings and declarations.
