SB 229: General Provisions – Commemorative Month – Maryland Native Plant Month

SB 229 designates May as Maryland Native Plant Month by requiring the Governor to annually issue a proclamation. The proclamation urges educational organizations, environmental groups, and businesses to host events and activities celebrating native plants. It defines "native plant" as species naturally occurring in Maryland before colonial settlement or listed on the Maryland Plant Atlas. The bill takes effect October 1, 2026, and creates no new funding or regulatory requirements - only an annual recognition effort.

HB 521: Electric Companies and Gas Companies - Customer Bill Surcharge - Repeal

HB 521 repeals a surcharge on electric and gas utility bills that previously funded energy efficiency programs supporting Maryland's greenhouse gas reduction goals. The bill removes the requirement for utilities to recover costs related to these programs through customer bills, eliminating a mandatory surcharge that had been in place since at least 2008. This directly affects residential and commercial utility customers who previously paid this fee, as it no longer requires utilities to include these costs in billing. The repeal also removes disclosure requirements about the surcharge's purpose and duration.

SB 108: Environment - Water Resources and Wetlands - Enforcement

SB 108 authorizes Maryland's Department of the Environment to impose administrative penalties for violations of water appropriation, dam safety, and wetlands development rules. It directly affects businesses, developers, and local governments that fail to comply with environmental regulations. Key provisions allow the department to levy fines up to $5,000 per violation (capped at $100,000 total), considering factors like environmental harm and willfulness, with penalties paid into the Maryland Clean Water Fund (or Private Dam Repair Fund for dam-related issues). The bill replaces some court-based enforcement with direct administrative penalties, streamlining enforcement while requiring department consultation before suing local governments.

HB 250: Environment - Appropriation or Use of Water and Dam Safety - Enforcement

HB 250 authorizes Maryland's Department of the Environment to impose administrative penalties for violations of water appropriation, dam safety, and wetlands rules. It directly affects businesses, developers, and dam operators who breach these regulations. Key provisions include setting penalties up to $5,000 per violation (capped at $100,000 total), requiring consideration of factors like environmental harm and willfulness, and mandating that collected penalties fund the Maryland Clean Water Fund (except for dam safety cases, which go to a repair fund). The bill also streamlines enforcement by allowing the Department to issue immediate corrective orders and hold expedited hearings for urgent threats.

SB 59: Transportation - Major Highway Capacity Expansion Projects and Impact Assessments (Transportation and Climate Alignment Act of 2026)

SB 59 requires Maryland’s Department of Transportation to conduct impact assessments for major highway expansion projects costing over $100 million, measuring their effects on greenhouse gas emissions and vehicle miles traveled. It mandates that projects include a multimodal transportation program (focusing on transit, bike paths, and pedestrian improvements) to offset emissions, with priority given to overburdened and underserved communities impacted by the project. The bill also requires the Department to evaluate all major capital projects in the Consolidated Transportation Program for climate impacts starting in 2028, aiming for net-zero or negative emissions from these projects. These requirements apply to projects not already funded or reviewed before 2026, aligning transportation planning with state climate goals.

SB 164: Natural Resources - Pamela J. Kelly Tree-Mendous Maryland Program - Alterations

SB 164 amends Maryland's Pamela J. Kelly Tree-Mendous Maryland Program to explicitly prioritize advancing forest health and resilience through the promotion and maintenance of native trees and shrubs. The bill directly affects the Maryland Department of Natural Resources (which administers the program), public land managers, community spaces, school grounds, and rights-of-way where tree planting occurs. Key provisions change the program's stated purpose in state law to require native species for all planting and maintenance efforts on public lands. This policy shift focuses on using locally adapted plants to strengthen ecosystems rather than non-native species. The bill takes effect October 1, 2026, pending final legislative approval.

HB 87: Income Tax - Energy Efficient Home Improvement Credit

HB 87 creates a Maryland income tax credit allowing homeowners to claim up to 30% of costs for qualifying energy-efficient home improvements, capped at $3,200 annually. It covers specific items like home energy audits ($150 limit), exterior windows ($600 total), doors ($500 total), heat pumps, and biomass stoves ($2,000 limit), all applied to the primary residence. The credit excludes improvements paid for with subsidized energy financing and requires documentation for verification. This policy takes effect for tax years beginning after December 31, 2025.

HB 517: Emission Standards, Ambient Air Quality Standards, and Solid Waste Management - Local Authority

HB 517 clarifies that counties and cities in Maryland can adopt stricter local emission standards or air quality rules than state or federal levels, provided their standards are equally or more stringent. It also confirms local governments retain authority to regulate solid waste management systems without being limited by certain state provisions. The bill requires the Department of the Environment to publish clear information about this local authority on its website by October 1, 2026. This law directly affects local governments seeking to implement more protective environmental regulations within their jurisdictions. It does not change existing state standards but removes ambiguity about local regulatory power.

HB 460: Solar Energy - Construction of Generating Stations in Priority Preservation Areas and Study

HB 460 limits solar energy generating station construction in Maryland's priority preservation areas (protected lands established before 2025) to 2% of the total acreage, down from a previous 5% cap. It requires counties to report when this 2% limit is reached and prohibits local zoning laws from blocking solar projects meeting specific criteria. The bill also mandates the Maryland Department of the Environment to study the environmental impact of disposing of solar panels at end-of-life and report findings by September 2027. This directly affects counties, developers, and landowners in priority preservation areas by restricting solar development space and creating new reporting requirements. The policy change aims to balance renewable energy growth with conservation of sensitive lands.

HB 647: Power Plant Research Program - Study on Nuclear Energy

HB 647 requires Maryland's Power Plant Research Program to study whether nuclear energy qualifies as a renewable resource and could help combat climate change. The study must evaluate current nuclear energy use in Maryland, identify environmental benefits, assess barriers to new nuclear projects, identify potential construction sites, and examine adding nuclear energy to the state's renewable energy goals. The program must submit findings and recommendations to the Governor and legislature by September 30, 2027. This bill directly affects the Power Plant Research Program and informs future energy policy decisions.
