HB 2239 requires new or expanded AI data centers (100+ megawatts capacity) built after August 28, 2027, to install closed-loop water cooling systems or equivalent alternatives. Operators must submit annual public reports detailing water use, energy sources, emissions, waste, and community health metrics. Failure to comply with cooling requirements or report submissions incurs daily civil penalties up to $50,000. The law mandates public access to these reports within 60 days of submission, enhancing transparency around environmental and health impacts.

SB 1210, the "Lithium Battery Recycling and Safety Act," requires battery manufacturers and recyclers in Missouri to join or form a representative organization that creates and maintains a statewide battery recycling program. The program must include annual collection targets based on past sales, approved collection sites, and public education, with all batteries disposed only at these designated sites after implementation. Manufacturers and recyclers must participate in the program to operate in the state, and annual reports detailing collection rates, finances, and facility use must be publicly posted. The law excludes medical, lead-acid, vehicle, and certain other battery types from its requirements.

HB 1925 bans the manufacture, sale, and use of firefighting foam containing intentionally added PFAS chemicals (known as "forever chemicals") in Missouri after January 1, 2028, with limited exceptions for airport use required by federal law or military defense applications. It requires immediate reporting of any foam discharge to the state environmental agency within 24 hours and mandates manufacturers to recall existing PFAS-containing foam while reimbursing buyers. The law aims to protect Missouri's water sources by regulating PFAS in firefighting foam, requiring manufacturers to provide certification of compliance. It directly affects foam manufacturers, fire departments, airports, and military facilities handling such foam.

HB 1624 requires seed permit applicants and nursery dealers in Missouri to include an affidavit stating they will not knowingly sell certain nonnative invasive plants as part of their permit or registration application. The affidavit specifically prohibits the sale of climbing euonymus, Japanese honeysuckle, Sericea lespedeza, and Perilla mint after January 1, 2027, and burning bush or Callery pear after January 1, 2029. This requirement is mandatory for obtaining or renewing a seed permit or nursery dealer registration, directly affecting nurseries and seed sellers who must comply to operate legally. The bill does not impose direct penalties but ties permit approval to adherence with these plant sale restrictions.
