This bill establishes a new chapter in Title 70A RCW aimed at preserving the productive potential of agricultural land, particularly focusing on highly erodible land. It introduces definitions for key terms such as "conservation plan," "highly erodible land," and "solar canopy." A conservation plan is defined as a strategy approved by the USDA's Natural Resources Conservation Service to reduce soil loss on designated highly erodible land. The bill also defines a solar canopy as an elevated structure containing a solar energy system with a minimum capacity of one megawatt.

Furthermore, the bill mandates that any developer, owner, or operator of a utility-scale solar canopy facility located on highly erodible land must comply with the approved conservation plan throughout the facility's operational life. Failure to comply will result in ineligibility for any tax preferences, deferrals, or incentives under Title 82 or RCW. This legislation aims to ensure that agricultural land is preserved while allowing for the development of renewable energy sources.
