This is an amendment to the grant regulations. EPA is amending regulations based on a determination that it is not practicable to award Toxic Substances Control Act (TSCA) compliance monitoring grant funds to States through a competitive process. Instead, EPA will award these grants to States on an allotment basis. Section 28 of TSCA authorizes EPA to award grants to States for the establishment and operation of programs to prevent or eliminate unreasonable risks to health or the environment associated with chemical substances or mixtures within the States with respect to which EPA is unable or not likely to take action for their prevention or elimination.
