Must every permittee have his or her own separate SWPPP or is a joint plan allowed?
The only requirement is that there be at least one SWPPP for a site that incorporates the required elements for all operators, but there can be separate plans if individual permittees so desire. ADEQ encourages permittees to explore possible cost savings by having a joint SWPPP for several operators. For example, the prime developer could assume the inspection responsibilities for the entire site, while each homebuilder shares in the installation and maintenance of sediment traps serving common areas.
