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.
