Regulations: biosolids, federal U.S.A. and Canada
United States Biosolids Regulations
The 1993 U. S. EPA regulations at 40 CFR Part 503 govern the use & disposal of wastewater solids (sewage sludge) in the U.S.

Canada Biosolids Approach
Canada does not have federal biosolids regulations. Provinces have jurisdiction on use and disposal of wastewater solids. In 2012, the Canadian Council of Ministers of the Environment (CCME) developed a national approach by agreement of the provincial environment ministers. It "promotes the beneficial use of valuable resources such as nutrients, organic matter and energy contained within municipal biosolids, municipal sludge and treated septage."
