MINOR

The bill expanded eligibility for individual wastewater systems by clarifying that they can serve up to five bedrooms regardless of how many separate dwellings or units those bedrooms are located in. This change addresses ambiguity in existing rules that previously limited systems to five bedrooms within a single dwelling unit or two dwelling units. The effective date was also changed from July 1, 3000, to December 31, 2050.

Scope change

The bill's scope was broadened to allow individual wastewater systems to serve bedrooms across multiple detached or attached dwelling units, not just within a single unit or two units.

ELIGIBILITY

Removed the restriction that five bedrooms must be in one dwelling unit or two dwelling units, allowing systems to serve up to five bedrooms regardless of the number of dwellings or units.

TIMELINE

Changed the effective date from July 1, 3000, to December 31, 2050.
