					 standard for picocuries per liter of radon gas. The U.S. environmental
					 protection agency (EPA) recommends that all homes that measure 4 pCi/L and
					 greater be mitigated. The EPA and the U.S. geological survey have evaluated the
					 radon potential in the U.S. and have developed a map of radon zones designed to
					 assist building officials in deciding whether radon resistant features are
					 applicable in new construction.
The map assigns each of the 83 counties in Michigan to 1
						of 3 zones based on radon potential. Each zone designation reflects the average
						short-term radon measurement that can be expected to be measured in a building
						without the implementation of radon-control methods. The radon zone designation
						of highest priority is zone 1. Table AF101 lists the zone 1 counties
						illustrated on the map. More detailed information can be obtained from
						state-specific booklets (EPA-402-R-93-021 through 070) available through state
						radon offices or from EPA regional offices.

Rule 711. Sections
						  101.1,
						  101.2, and
						  101.3 of the code are amended to
						  read as follows:
101.1. Title. This
						part shall be known as the Michigan plumbing code and is to be referred to as
						"the plumbing code" or "the code." This part shall control all matters
						concerning the installation, replacement, alteration, relocation, and use of
						plumbing systems or plumbing materials as defined in this code and shall apply
						to existing or proposed buildings and structures in this state.
101.2. Scope. The design and installation of
						plumbing systems, including sanitary and storm drainage, sanitary facilities,
						medical gas systems, water supplies, water service, and storm water and sewage
						disposal in and exiting buildings, shall comply with the requirements of the
						code. The design and installation of gas piping, chilled water piping in
						connection with refrigeration process and comfort cooling, and hot water piping
						in connection with building heating systems shall conform to the Michigan
						mechanical code. The design and installation of all fire sprinkler systems and
						standpipe systems shall conform to the Michigan building code. Water and
						drainage connections to such installations shall be made in accordance with the
						requirements of the code.
Exception: Detached 1-and 2-family dwellings and
						  multiple single-family dwellings, such as townhouses, not more than 3 stories
						  high with separate means of egress and their accessory structures shall comply

						the Stille-DeRossett-Hale single state construction code act, 1972 PA 230, MCL
						125.1501 to
						125.1531 is to establish minimum
						standards to provide a reasonable level of safety, health, property protection,
						and public welfare by regulating and controlling the design, construction,
						installation, quality of materials, location, and operation and maintenance or
						use of plumbing equipment and systems. The Stille-DeRossett-Hale single state
						construction code act, 1972 PA 230, MCL
						125.1501 to
						125.1531, takes precedence over
						all provisions of this code.
