That depends. There may be some confusion and assumptions out there. Federal facilities may be required to pay local stormwater utility fees. According to § 15.2-2114. Regulation of stormwater of the Code of Virginia http://lis.virginia.gov/cgi-bin/legp604.exe?000+cod+15.2-2114 , Federal facilities are subject to stormwater utility fees, except if the facility “…holds a permit to discharge stormwater from a municipal separate storm sewer system; except that the waiver of charges shall apply only to property covered by any such permit.” Read more about it here – http://www.stormh2o.com/SW/Blogs/1722.aspx
