Element 4 - Nonpoint Source Management Planning

With the enactment of Section 319 of the Clean Water Act of 1987, federal financial assistance was authorized for the implementation of state nonpoint source (NPS) management planning programs. Since 1996, NPS management planning has increased as a direct result of EPA providing grants to states to implement NPS programs. Missouri's Nonpoint Source Management Plan (NPSMP) is prepared by the department in cooperation with partner agencies and Missouri citizens in response to the requirements of Section 319. Missouri periodically reviews and evaluates its NPSMP, revising it every five years.

Statewide watershed planning efforts are conducted at the eight-digit HUC watershed scale and provide direction and focus for all of the department’s programs. It is the top priority of the Missouri NPSMP to protect the state’s water resources. Watershed planning recognizes the nexus between local citizen engagement and the development and implementation of successful watershed-based plans and policies. The watershed planning efforts also provide opportunities for local citizens and leaders to provide input and influence decisions regarding water resource priorities and goals.

The NPSMP will concurrently act as the framework for coordinating resources between the department and its partner organizations to enhance the success of actions that address local priorities. The department is also committed to ensuring that these efforts are responsive to local conditions and continuously adapt to new information.

During implementation of the current NPSMP (2015–2019), multiple sources of funding including, federal Section 319 grant funds and other state and federal funds, will be used in developing and implementing nine-element watershed-based plans. Those plans will identify realistic pollution load reduction goals based on the conservation practices that local producers and municipalities have indicated they are willing to implement. Specific areas where conservation practices need to be implemented will be determined through watershed assessments and stakeholder input. The duration of the watershed-based plan will be the estimated number of years needed to meet NPS pollutant load reduction goals. The watershed planning efforts are based on HUC-8 watersheds, but focus on priorities within smaller watersheds and catchment basins. Every five years, the watershed planning cycle will be repeated by reassessing the results from previous watershed-based plans and using adaptive management to build upon earlier successes. The watershed planning and implementation process will be continued over time in all 66 HUC-8 watersheds of the state in conjunction with the annual Missouri watershed planning cycles.
