Mayor Dan and Mr. & Mrs. Valantas,

Not only is DeArmoun Road state owned but, as Mr. Sullivan likely recalls from his public service, the Alaska Pollution Discharge Elimination System (APDES) permit requires all Municipal and State owned roads with in the Municipality of Anchorage to be swept a total of three times per year, regardless of how clean they may appear.  (As an aside, in some cases the municipality maintains, or contracts for maintenance of, state owned roads under a Transfer of Responsibilities of Agreement with DOT.)

If you don't think Hillside roads need the level of street sweeping they currently receive I suggest contacting your state legislators to work with the Department of Environmental Conservation on changes to the APDES permit, though I seem to recall the permit is part of our PM 2.5 (fine particle)  containment strategy required by the EPA.  Those little bits of matter are the ones that can really damage your lungs.

Good luck!
Happily retired Assembly member
