As part of this credit, the project is to employ a building exterior and hardscape management plan that uses best management practices to reduce air pollution and chemical runoff compared with standard practices.Propane-powered equipment, in place of all gasoline-powered equipment, is an acceptable site management strategy to demonstrate compliance for this part of the credit. Propane conversion for 2 cycle equipment, and 24 inch or smaller push mowers, is not currently available and therefore is not required at this time.
