Hazardous waste disposal; revise certain provisions regarding.

HB 1621 removes specific restrictions on hazardous waste disposal in Mississippi. It eliminates the prohibition on underground injection methods for hazardous waste (amending Section 17-17-27) and deletes requirements for the Permit Board to consider Mississippi's capacity plan or interstate agreements (amending Section 17-17-151). The bill also removes legislative findings about federal law compliance (amending Section 17-17-153). These changes would directly affect commercial hazardous waste facilities seeking permits and the Permit Board’s review process.
