This bill updates Connecticut's property tax exemption rules for renewable energy systems, expanding eligibility for homeowners, farms, and businesses while clarifying how exemptions are calculated. It allows property tax exemptions for residential solar, wind, and geothermal systems installed on or after October 1, 2007, and extends similar benefits to commercial and industrial renewable energy projects installed between 2010 and 2013 in specific municipalities. The legislation also establishes new exemption categories for commercial solar and wind projects installed after 2014, with additional restrictions taking effect in 2025 and 2026 that limit exemptions to the equipment itself rather than the entire property value. These changes apply to Class I renewable energy sources including solar, wind, geothermal, and hydropower facilities that generate electricity for on-site use.
This bill requires the creation of a nonprofit beverage container stewardship organization that will manage the state's bottle deposit program. The organization must be run by deposit initiators, operate as a tax-exempt entity, and demonstrate strong financial controls to prevent fraud. Companies selling beverage containers must join this organization within three months of its approval, and the organization must develop a detailed plan to achieve an 80% redemption rate while ensuring financial self-sustainability. The plan must include input from various stakeholders and outline how recovered materials will be recycled, with annual reports submitted to the commissioner to track compliance.
HB 5282 requires state agencies to align major projects costing over $1 million (up from $200,000) with Connecticut's State Plan of Conservation and Development. This affects all state agencies using state or federal funds for property acquisition, development, or public transportation projects exceeding the threshold. The bill mandates agencies to submit conformity notices to the secretary and establishes an annual inflation adjustment for the $1 million threshold using the Producer Price Index. Municipalities must also reference the state plan in new conservation and development plans adopted after 2026.
HB 5241 establishes a pilot program in a city with over 148,000 residents to test a "Triple Bottom Line Justice" approach, which integrates environmental cleanup, health equity, and community engagement. The program requires state health and environmental agencies to partner with a local community organization to use ICD-10 Z codes (which track social and environmental health factors) in healthcare billing, aiming for 20% adoption by 2030. It mandates annual reports on progress, develops educational materials for healthcare providers on these codes, and evaluates how transforming polluted sites ("Brownfields to Healthfields") can reduce long-term health costs. The pilot must conclude by January 2028 with a final report to the legislature.
HB 5155 requires Connecticut's Department of Energy and Environmental Protection to create an online database tracking pesticide sales and use by December 2028, replacing older reporting methods. The database will make public access to historical pesticide data (from Chapter 441 of state law) and include pesticide-treated seed information collected with the Department of Agriculture. It allocates $100,000 for development in fiscal year 2027. This directly affects pesticide sellers and users (who must report through the new system) and provides the public with clearer access to where, what, and how much pesticides are used statewide.
SB 147 directs the Commissioner of Energy and Environmental Protection to study whether extended producer responsibility programs are needed for recycling solar panels and vapes, focusing on material reuse, fire safety, and cost comparisons. The study will assess the volume of solar panels expected to be discarded in the next five years, fire risks from vape disposal, current disposal costs versus potential program costs, and required infrastructure for such programs. It also expands the existing paint stewardship program to include aerosol paints under the definition of "architectural paint." The Commissioner must submit a report with findings and recommendations by January 1, 2027.
SB 306 requires Connecticut's Commissioner of Energy and Environmental Protection to develop a Comprehensive Energy Strategy every four years (starting October 1, 2020), which must address all state energy needs (electricity, heating, cooling, transportation), meet greenhouse gas reduction goals, and incorporate existing energy plans. The strategy must include cost assessments, public input through meetings and a 60-day comment period, and analyze natural gas expansion, efficiency goals, and rate impacts. It directly affects state agencies, utilities (via the Public Utilities Regulatory Authority's comments), and residents through potential energy cost and service changes. The bill mandates specific content and public engagement procedures but does not create new funding or impose direct costs on individuals.
SB 148 clarifies the process for closing shellfish harvesting areas due to contamination or pollution. It requires the department to establish exact boundaries for closed areas and ensure closures take effect only after publishing notices in local newspapers, filing documents with town clerks and health directors, posting signs at the site, and updating the department’s website. The bill also specifies that during a health emergency, the Commissioner of Agriculture can immediately close affected areas by notifying health authorities and publishing a public notice. This directly affects shellfish harvesters, coastal communities, and health departments by standardizing how closure information is communicated. The bill repeals outdated language in existing statutes to modernize the notification system.
SB 9 provides a tax credit for Connecticut businesses with 100 or more employees in federally designated "severe nonattainment" air quality areas (as defined by the Clean Air Act). The credit covers 50% of eligible spending on commuting programs that reduce single-occupancy vehicle trips, including public transportation, carpooling, or microtransit services, up to $250 per employee annually, with a total annual cap of $1.5 million. Businesses must submit a plan to the state transportation department detailing how they will implement these programs to qualify for the credit.
HB 5401 updates how Connecticut adopts and revises its State Building Code. It requires the State Building Inspector and Codes Committee to base the code on a nationally recognized model, limits revisions to once every six years (or per two model cycles), and mandates provisions for energy conservation and EV charging circuits in new residential garages. The bill also imposes a temporary pause on new building standards from October 2026 to October 2032, except for safety, federal funding, or accessibility needs, and prohibits local municipalities from enforcing stricter rules than the state code during this period. Additionally, it requires mandatory training for building code officials and professionals like architects and contractors on the State Building Code and Fire Safety Code.
