some info on just one type of permit needed to run such a facility.permits are site specific and one permit can not cover multiple sites unless they are in a specific area.I don't believe crossing state lines is in the same specific area. http://cfpub.epa.gov/npdes/permitissuance/genpermits.cfm and maybe this would help http://www.epa.gov/enviro/facts/multisystem.html
