EPA regulates large on-site wastewater systems under 40 CFR Part 503 and Section 503 of the Clean Water Act; smaller residential systems are state-regulated. The federal Public Utility Regulatory Policies Act (PURPA) requires utilities to interconnect qualifying small power producers but does not mandate off-grid permissions. NSF/ANSI Standard 41 governs composting toilet performance. Local zoning, HOA covenants, and building codes are often more restrictive than state law.
