House Bill No. [insert bill number] aims to revise sanitation laws related to subdivisions in Montana. The bill prohibits local boards of health from adopting regulations that would permit a mixing zone to encroach on adjacent properties. It clarifies that the Sanitation in Subdivisions Act does not apply to certain drainfield mixing zones and revises the definition of "proposed drainfield mixing zone." Specifically, for parcels created after March 30, 2011, the bill prohibits the construction of subsurface wastewater treatment systems if the associated mixing zone would encroach onto adjacent property, except as allowed in specific circumstances outlined in the law.

Additionally, the bill amends sections 50-2-116 and 76-4-102 of the Montana Code Annotated (MCA). It updates the definition of "proposed drainfield mixing zone" to include only those submitted for approval after March 30, 2011, and clarifies that it does not include mixing zones approved before this date or under certain conditions before October 1, 2025. These changes aim to enhance public health protections and ensure that local health regulations align with state standards while preventing potential conflicts with adjacent property rights.
