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.

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.

HB 547: Income Tax - Enhanced Agricultural Management Equipment Subtraction Modification and Parent of a Stillborn Child Credit

HB 547 expands Maryland's income tax deduction for agricultural equipment by allowing the Secretary of Agriculture to add new equipment types through regulation. This directly affects Maryland farmers who purchase qualifying equipment, including technologies that reduce soil disturbance and nutrient runoff. The bill modifies existing tax rules (Section 10-208(d)) to include "enhanced agricultural management equipment" determined by the Secretary, beyond the current list of specific items like no-till planters or manure injection systems. Farmers must still meet standard requirements, such as owning equipment for at least three years and using it in agricultural production.

HB 613: Department of the Environment - Waivers for Living Shorelines and Nonstructural Shoreline Stabilization Measures - Regulations and Scoring System

HB 613 requires property owners in Calvert and St. Mary's Counties to use natural erosion control methods (like marsh creation, native plants, and oyster reefs) instead of hard structures (such as seawalls) for shoreline stabilization. It exempts these counties from general state requirements for nonstructural measures and creates a new waiver process where owners must demonstrate to the Department of Natural Resources that natural methods are not feasible due to factors like extreme erosion or narrow shorelines. The bill defines "living shorelines" as projects using natural materials and ecological principles to absorb wave energy and restore habitats, while still allowing structural measures in specific high-energy areas. This directly affects property owners along navigable waters in those two counties, changing how they must address shoreline erosion.

HB 1621: Wastewater Treatment Plants - Discharges - Requirements

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 196: Public Health - Baby Food Testing and Labeling - Requirements

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.
