SB 523: Department of Natural Resources - Water Resources - Identification of Vernal Pools (Jack Cover Vernal Pools Act of 2026)

SB 523 requires Maryland's Department of the Environment to create regulations protecting "qualified vernal pools" - seasonal wetlands that don't meet federal wetland criteria but support species like wood frogs and salamanders. It mandates the department to maintain a list of these pools, establish protective buffers, and require developers to avoid harming them during activities like construction. If harm is unavoidable, developers must minimize damage and provide compensation through the department. This directly affects landowners, developers, and construction projects near these pools, adding regulatory requirements similar to those for existing wetlands. The bill does not change current protections for federally recognized wetlands.

HB 833: Commission to Advance Lithium-Ion Battery Safety in Maryland - Reestablishment

HB 833 reestablishes Maryland's Commission to Advance Lithium-Ion Battery Safety with updated membership and a focused mandate. The commission, composed of 27+ members including state agencies, fire departments, battery manufacturers, recyclers, and industry representatives, will study key safety issues like preventing fires in consumer/transportation applications, recycling standards, port/rail risks, and insurance impacts. It must submit an interim report by December 1, 2026, with recommendations on best practices, training, and regulatory approaches. This bill directly affects state agencies, first responders, and industries handling lithium-ion batteries, but does not enact new laws - only directs the commission to study and advise.

HB 925: Sewage Sludge - Per- and Polyfluoroalkyl Substances - Regulation

HB 925 establishes limits on per- and polyfluoroalkyl substances (PFAS) in sewage sludge applied to land, prohibiting use if PFAS levels exceed specific thresholds after a set date. It directly affects sewage sludge generators (like wastewater treatment facilities), industrial users discharging PFAS, and local jurisdictions managing sludge. Key provisions include mandatory PFAS monitoring in sludge, requirements for industrial pretreatment standards when PFAS levels exceed action levels, and rules allowing limited blending of sludge from multiple sources. The bill also authorizes local fees for industrial dischargers and updates regulations for safe land application practices.

SB 719: Sewage Sludge - Per- and Polyfluoroalkyl Substances - Regulation

SB 719 restricts the land application of sewage sludge containing per- and polyfluoroalkyl substances (PFAS) above specific concentration levels, effective after a set date. It requires monitoring for PFAS in sewage sludge and products containing it, authorizes stricter pretreatment rules for industrial users discharging PFAS, and allows local jurisdictions to set fees for such discharges. The bill directly affects sewage sludge generators (like wastewater treatment facilities), industrial users, and local regulators by mandating new PFAS testing, usage limits, and fee structures. It amends Maryland’s environmental code to establish these requirements without changing existing land application rules for sludge below the new PFAS thresholds.

HB 784: Aquaculture - Placement of Shellfish, Bags, Nets, and Structures on Submerged Aquatic Vegetation - Extension

HB 784 extends the authorization period for aquaculture leaseholders in Maryland to place shellfish, bags, nets, and structures on submerged aquatic vegetation, requiring prior written approval from the Department of Natural Resources. It changes the expiration date from June 30, 2027, to June 30, 2030, extending the authorization by 3 years and 1 month. The bill specifies that the Department must allow water column leases to use at least 10% of vegetation areas and prohibits dredge harvesting in vegetation zones. This directly affects commercial shellfish aquaculture operators holding leases in Maryland waters. The change maintains existing restrictions while prolonging the current regulatory framework.

SB 940: Environment - Water Quality Testing - Secondary Maximum Contaminant Levels Action Plan

SB 940 requires Maryland's Department of the Environment to create and implement a mobile home park water quality testing program by January 1, 2027. The program mandates testing at 25% of parks by 2028, 50% by 2029, 75% by 2030, and 100% by 2031, prioritizing parks with 40%+ minority residents, areas with known geological contaminants, parks where residents requested testing or filed complaints, and parks using private water supplies. Park owners must take corrective actions if water quality issues are identified, and the Department must provide results to residents in multiple languages. This bill directly affects mobile home park owners and residents across Maryland by establishing a structured process to ensure drinking water safety.

HB 35: Local Government - Regulatory Powers - Regulation of Invasive Trees

HB 35 authorizes Maryland counties and municipalities to create local rules regulating Tree of Heaven (an invasive species), directly affecting property owners and local governments. The bill allows communities to ban the sale, planting, or growth of Tree of Heaven on private property, and requires property owners to remove it. Local governments may also establish cash reward programs to incentivize removal, and enforce rules through civil fines or requiring damage mitigation. This bill provides concrete tools for local management of the invasive tree without mandating statewide action.

SB 166: Shellfish Aquaculture - Penalties - Suspension or Revocation of Permit or Registration Card

SB 166 authorizes Maryland's Department of Natural Resources to suspend or revoke shellfish aquaculture harvest permits or registration cards for specific violations, directly affecting commercial shellfish harvesters. Key violations include harvesting in closed areas, exceeding time restrictions for oyster harvesting, or harvesting without proper authorization. For a first violation, permits may be suspended for up to 5 years; repeat violations result in permanent revocation. The bill also prohibits anyone with a suspended or revoked permit from working in any aquaculture activity during the penalty period. This legislation takes effect October 1, 2026.

SB 266: Local Government - Regulatory Powers - Regulation of Invasive Trees

SB 266 authorizes Maryland counties and municipalities to adopt local ordinances regulating the invasive Tree of Heaven (Ailanthus altissima), a nonnative tree that spreads aggressively and harms native ecosystems. The bill allows local governments to ban selling, planting, or allowing the tree to grow on property, require containment if it's present, and impose civil fines for violations. It also permits communities to create bounty programs incentivizing residents to remove the tree. This directly affects property owners who may have the tree and local governments seeking to manage its spread.

HB 258: Chesapeake and Atlantic Coastal Bays Critical Area Protection Program - Standards and Procedures

HB 258 updates Maryland's rules for development near the Chesapeake and Atlantic Coastal Bays. It requires local governments to conduct 10-year reviews of their critical area programs, sets specific location rules for new development (like maintaining 300-foot buffers from tidal wetlands), and mandates climate vulnerability assessments for projects. The bill also clarifies procedures for correcting mapping errors and updating tree replanting requirements. These changes directly affect 12 coastal Maryland counties (including Calvert and Talbot) that manage local development plans under the program. The law aims to strengthen protections for bay ecosystems through clearer, updated standards for land use decisions.
