Dear Mr. Scheben:
SUBJECT: GAAB - WOODLAND LAKES DEVELOPMENT
I am writing in regard to the 540' sewer extension from MH W24-28A along
Cranberry Road to the existing sewer line on W 68th Avenue. The plan
for this proposal was forwarded to this Department for our review via Mr.
Kyle Cherry of our Anchorage office. No specifications were received but
your forwarding letter to Mr. Cherry stated that the GAAB Standards and
Specifications would be used for this construction.
Our only comment is that compliance must be made with the recently enacted
air pollution regulations of this Department during the building of this
line. A copy of these regulations is enclosed.
The plan is approved by this Department. Please complete and return one
of the two attached Applications for Approval of Plans.
Sincerely yours,
Ronald G. Hansen~ Chief
