It looks like CAL Green requires Storm Water Pollution Prevention to be implemented for new projects that disturb under one acre,
However, If a project disturbs over one acre A Storm Water Pollution Prevention Plan is required the The State Water Resource Control Board under the Construction General Permit Order.
Does anyone know how SWPP is enforced or what is required specifically? I'm guessing each jurisdiction may have their own specific requirements to accommodate this portion of the code? compared to the SWPPP which is likely a much more elaborate, detailed, and calculated solution, enforced by the SWRCB, correct?
