Modifies criteria of hazardous waste investigations and increases the hazardous waste fund appropriations

HB 1673 creates a dedicated fund within the hazardous waste fund to finance investigations into potential radioactive waste contamination. Local governments can request these investigations by submitting a written request detailing a specific area of concern, which the state department of natural resources must prioritize based on receipt date or proximity to known federal sites. The bill outlines a process where qualified contractors collect soil, dust, and water samples to test for radioactive isotopes, with homeowners consenting to testing inside their residences. Results from these investigations must be reported to local officials and made publicly available online within 45 days of receiving the final data. The legislation also sets annual spending limits of $300,000 for both the transfer into the new fund and the actual investigation costs.
