Hazardous Materials - As enacted, makes various changes to the "Tennessee Drycleaner's Environmental Response Act." - Amends TCA Title 68, Chapter 217, Part 1.

HB 1632 amends Tennessee's Drycleaner's Environmental Response Act to clarify program definitions and expand cleanup coverage. It adds "soil gas vapor" (including sub-slab vapor and indoor air) to the types of contamination the drycleaner environmental response fund addresses, and updates definitions for "recently abandoned" facilities, "registered facilities," and "wholesale distribution." The bill also revises registration requirements, requiring drycleaning facilities and wholesale distributors to register annually to access the fund, with non-compliance risking removal. These changes primarily affect drycleaning businesses, wholesale solvent distributors, and the state environmental agency managing the fund.
