The Western Upper Peninsula Health Department (WUPHD) is opening a 30-day public comment period on the updated U.P. Environmental Health Code. The code mainly oversees the permitting and construction of on-site sewage systems and water wells in Baraga, Gogebic, Houghton, Keweenaw, and Ontonagon Counties. The code was last changed in 1997. Proposed changes to the code will generally loosen restrictions and include language that recognizes technical advances. WUPHD says looser restrictions could provide homeowners with some relief.
