The "Grants for Eliminating the Toxic Hazard of Environmental Lead in Our Towns Act of 2026" or "GET THE LEAD OUT Act of 2026" seeks to develop a comprehensive national strategy to evaluate and reduce lead-based pipe and tap hazards in housing. Its core purposes include preventing childhood lead poisoning, mobilizing national resources through public-private partnerships, and educating the public on lead hazards. Title I authorizes the Secretary of Housing and Urban Development (HUD) to provide grants to states and local governments for evaluating and reducing lead-based pipe hazards in priority housing. These grants can fund risk assessments, inspections, interim controls, abatement, temporary relocation assistance, and public education. The bill also mandates risk assessments, inspections, and abatement procedures for federally assisted housing, including public housing, and integrates lead hazard reduction into programs like HOME Investment Partnerships and Community Development Block Grants. Furthermore, Title I establishes a task force, in consultation with the Environmental Protection Agency (EPA), to recommend strategies for financing lead-based pipe hazard reduction in private housing. It also requires the Secretary and EPA Administrator to issue regulations for disclosing lead-based pipe hazards in residential property transfers, including a Lead Warning Statement and a 10-day inspection period for purchasers. Title II focuses on lead exposure reduction, directing the EPA to promulgate regulations for training and certification of contractors involved in lead-based pipe activities. It also requires the EPA to identify dangerous levels of lead and establish a program for authorizing state-level lead hazard reduction programs. The bill mandates public education campaigns, including a National Clearinghouse on Childhood Lead Poisoning and a hotline, to raise awareness among health professionals, the public, homeowners, and the real estate industry. Title III authorizes significant appropriations for these efforts, including $9.5 billion annually for fiscal years 2026 through 2035 for HUD grants and necessary sums for EPA activities. These funds are intended to support the comprehensive evaluation, reduction, and prevention of lead-based pipe hazards nationwide. Finally, Title IV introduces revenue provisions to help fund the bill's initiatives. It modifies the tax treatment of partnership interests transferred in connection with investment management services, recharacterizing certain capital gains as ordinary income and applying self-employment taxes. Additionally, it aims to return the estate and gift tax basic exclusion amount to its pre-2018 levels by striking a specific subparagraph from the Internal Revenue Code.
