Declares that: (1) The protection of normal and customary agricultural practices upon agricultural land is essential to maintaining the public welfare in its highest state, supporting the farm and ranch capacity to produce good local food, and preserving open spaces; and

(2) State and federal agencies, in working to achieve nonpoint agricultural water quality improvements, must also take precautions to protect the economic viability of agricultural operations and minimize the conversion of agricultural land to other uses.

Provides that the legislature intends that normal and customary agricultural activities protected from over-regulation under federal law be granted equivalent protection from over-regulation under state law.

Directs government agencies tasked with protecting water quality to work cooperatively with agricultural landowners and conservation districts in order to fully utilize new and existing voluntary incentives and promote nonpoint agricultural water quality solutions to the maximum extent practicable before taking any nonpoint water quality enforcement action.
