The RRP Rule applies in states and tribal areas that are not operating EPA-authorized programs.  A firm with Federal certification under the RRP Rule may perform, offer, or claim to perform renovations in any of these states.  In states and tribal areas with EPA-authorized programs, check with the state or tribal agency administering the program to learn about the certification requirements in that state or tribal area.  EPA encourages authorized state and tribal programs to accept certifications issued under the Federal program and under other state and tribal programs, but this is not required.
