A bill meant to keep the federal government from enforcing updated regulations on wood burning stoves and furnaces has been endorsed by the Missouri House of Representatives. The Environmental Protection Agency has proposed standards for makers of wood stoves in its aim to reduce emissions by nearly 80 percent. Manufacturers testified before lawmakers telling them the new standards would make stoves too costly for most consumers and could put them out of business. The proposed legislation would also prohibit the State Department of Natural Resources from regulating the use or manufacture of wood stoves without approval of the General Assembly.
