H.R. 5040 directs the U.S. Environmental Protection Agency to establish national standards for toxic mold inspectors, and for "design, manufacture, and installation of air conditioning systems and units regarding sizing and capacity of systems and units, maintenance, prevention of water leaks, and other variables that may affect mold levels in buildings."

It includes promotion of research, public education, as well as a national insurance program. Conyers also proposes that the EPA establish guidelines to prevent toxic mold from entering lumber and drywall. Seventeen members of the House have co-sponsored the legislation, which has been referred to four House committees: Ways and Means, Energy and Commerce, Financial Services, and Judiciary.
