The bill amends the "Hazardous Waste Management" chapter of the General Laws by introducing a new definition for "Fill" and clarifying that "Hazardous waste" excludes waste recycled as legitimate recycled hazardous waste according to title 40 of the CFR section 260.43. It also establishes criminal penalties and mandates the payment of restoration costs for violations related to hazardous waste management, making it a felony to refuse to obey or knowingly violate orders, tamper with testing wells, dispose of hazardous waste at unpermitted facilities, operate a hazardous waste disposal facility without a permit, or transport hazardous waste without a permit.

The bill further prohibits the use of hazardous waste as fill on any construction site project in Rhode Island, making it a felony to knowingly use or transport hazardous waste for such purposes. It requires convicted individuals to pay for containment, cleanup, restoration, and removal of the fill, as well as any resulting damages. The bill changes the court's discretion from "may" to "shall" in ordering defendants to pay for or perform restoration, outlines procedures for determining restoration costs, and allows for treble damages in cases of willful and knowing violations. The act is intended to take effect upon passage, reinforcing the enforcement of hazardous waste management regulations to safeguard the environment and public health.
