HB 736 Montana House · 2025 Regular Session

Provide nutrient pollutant loading offsets

HB 736 establishes a system for nutrient pollutant loading offsets for facilities holding water quality discharge permits. It allows these permitted dischargers to meet their nutrient discharge limits by reducing nutrient pollution from other sources within the same watershed, including both direct discharge points and diffuse sources. The bill specifies varying offset percentages based on the type and location of the pollution reduction. It directs the state's environmental department to establish statewide offset values for various nonpoint pollution reduction projects, such as riparian fencing or wetlands development, and to amend existing policies to implement these provisions.

MODERATE
The bill was revised to simplify its title by removing 'pollutant' from 'nutrient pollutant loading offsets' and adding 'trading credits' to the title. The substantive changes focus on clarifying how nutrient loading offsets and trading credits are calculated and applied to water quality discharge permits, particularly for nonpoint sources like agricultural runoff.
Scope change
The bill's scope remains focused on water quality discharge permits, but the language now more clearly distinguishes between point source and nonpoint source reductions and their respective credit values.
REQUIREMENT

Changed the calculation percentages for trading credits: point source reductions still get 100%, up-gradient nonpoint sources get 80%, and down-gradient nonpoint sources get 50%.

TECHNICAL

Removed 'pollutant' from the term 'nutrient pollutant loading offsets' in the title and throughout the text, simplifying the language to 'nutrient loading offsets'.

Updated the measurement criteria for riparian fencing programs from 'number of acres fenced feet of streambank' to just 'number of feet of streambank', removing the acreage requirement.

Reorganized the structure of Section 1 to separate the definition of offsets from the specific measurement methodologies, making the bill easier to read and apply.

Removed redundant phrases like 'pollution discharger' and 'pollution sources' where 'source' alone was sufficient, streamlining the language.
