HB 1621 requires wastewater treatment plants processing over 50 million gallons of effluent daily to monitor discharges for hormones, PFAS chemicals, and bacteria, and publicly post daily bacterial levels and incident reports (like overflows) on their websites within 24 hours. It establishes bacterial safety thresholds requiring immediate public alerts when exceeded and bars non-compliant plants from Maryland's Water Quality Trading Program. Smaller plants (under 50 million gallons daily) must report staffing plans annually instead of daily data. The bill mandates transparency through public websites and gives the Department authority to enforce these requirements.
HB 701 requires Maryland's Department of the Environment to create regulations protecting "qualified vernal pools" - seasonal water bodies that support species like wood frogs but don’t meet federal wetland criteria. The bill mandates the department to identify these pools, establish protective buffers around them, and require developers to avoid, minimize, or mitigate impacts during projects. It directly affects landowners and developers planning construction or land-disturbing activities near these pools. The law aligns buffer and mitigation rules with existing protections for nontidal wetlands, ensuring consistent regulatory standards.
HB 1067 requires Maryland's Department of Natural Resources to phase out lead ammunition for hunting all game species by July 1, 2029. It directly affects hunters using firearms for deer, upland game birds, migratory birds, turkey, and other game, with earlier deadlines: pen-raised birds by 2027, upland/migratory birds and turkey by 2028, and deer by 2029. The bill mandates non-lead ammunition (defined as <1% lead content or federally approved non-toxic options) but allows exceptions for muzzleloaders, handguns, rifles, and shotguns if non-lead ammo isn't commercially available. The law requires the department to adopt regulations for each phase and make them available with hunting licenses. This policy aims to reduce lead exposure in humans (from consumed venison) and wildlife (from carcasses).
HB 817 requires Maryland's Department of the Environment to create permitting regulations for certified carbon removal technologies and practices by January 1, 2028. It mandates all state agencies to use existing funding to support carbon removal projects using technologies certified by internationally recognized third parties. The bill directly affects state agencies (which must allocate funds) and carbon removal technology providers (which must meet certification standards to qualify for permits). It aims to streamline regulatory processes by replacing outdated solid waste rules with new, technology-specific requirements.
HB 437, the Transportation and Climate Alignment Act of 2026, requires Maryland’s Department of Transportation to conduct impact assessments for major highway expansion projects costing over $100 million. These assessments must evaluate greenhouse gas emissions and vehicle miles traveled, and the department must develop a multimodal transportation program (including transit, biking, and pedestrian improvements) to offset emissions from the project. The program must prioritize overburdened and underserved communities affected by the project, aiming for net-zero or negative greenhouse gas emissions when combined with the highway project. This applies to projects not already funded or reviewed before June 30, 2026, and affects highway planning decisions across the state.
HB 146 requires landlords of properties with on-site wastewater systems (like septic systems) to ensure the system is inspected and pumped by a licensed professional before each new tenant moves in, starting July 1, 2028. It also mandates that real estate sales contracts for such properties include a condition requiring the buyer to confirm the system has been inspected and pumped by a licensed professional before closing. The law allows inspections and pumping services to remain valid for three years and requires property owners to notify authorities if a system fails. Exemptions include transfers between family members, refinancing, or initial construction. The bill sets deadlines for the state to adopt regulations (by 2027) and license service providers (by 2028).
HB 196 amends Maryland's definition of "baby food" to explicitly include infant formula and infant cereal (previously excluded), directly affecting baby food manufacturers in the state. The bill requires manufacturers to test each production batch of baby food for toxic metals (arsenic, cadmium, lead, mercury) starting January 1, 2025, using accredited labs at least monthly. Beginning January 1, 2026, manufacturers must publicly post test results online for each product and include QR codes on labels linking to FDA information about metal testing and health effects. The law aims to increase transparency and safety for infants under age 2 by aligning testing requirements with FDA standards.
HB 164 establishes new rules for handling yard waste collected on state-owned buildings and highways in Maryland. It requires workers to collect waste in reusable containers or compostable paper bags (not single-use plastic) and mandates disposal at specific facilities like organics recycling centers, natural wood recycling facilities, or state sites that create mulch. The bill applies to anyone employed to manage yard waste on state properties, excluding noxious weeds or invasive species. These requirements take effect October 1, 2026, aiming to improve waste management practices for state grounds.
