§319 grants are awarded annually on a competitive basis. A successful grant must focus on improving the water quality of lakes, streams, rivers, and aquifers. Funds may be used to address a variety of NPS management and prevention activities, including:
- Agriculture (except those activities covered by a draft or final IPDES permit).
- Urban Stormwater Runoff (except instances covered by a draft or final IPDES permit).
- Transportation (except instances covered by a draft or final IPDES permit).
- Silvicultural or Forestry-related Activities.
- Mining (except those activities covered by a draft or final IPDES permit).
- Ground Water Activities (to the extent identified by the state’s NPS management program, including source water protection efforts that involve regional collaboration or have statewide application).
- Hydrologic and Habitat Modification and Related Activities (including wetlands reconstruction).
Idaho passes through the large majority of its §319 funds to the local organizations to support TMDL implementation projects. Remaining funds are used to support administration and implementation of the NPS Management Program and regional office activities.
The Idaho Legislature provides additional appropriation dollars annually to supplement the §319 grant program, fund implementation of agricultural BMPs, and to reduce NPS pollution.
