Title 40 is the section of the CFR that deals with protection of the environment and our mission of protecting human health and the environment. The links below will direct you to the e-CFR. The e-CFR is not an official edition of the CFR, which is printed annually by the Government Printing Office (GPO).  However, GPO updates the e-CFR daily, making it a more current if unofficial version.
