FAA Response: No. The FAA will not approve an ALP at ASE that does not meet the 400’ runway/taxiway separation standard. In 2013, Pitkin County submitted an ALP update showing 320’ runway/taxiway separation on the west side of the airfield. We responded with the following in the ALP approval letter:
The FAA’s approval of this ALP does not apply to the proposed runway/taxiway separation distance of 320’ on the west side of Runway 15/33. FAA is evaluating this nonstandard separation distance and will continue to coordinate the issue with Pitkin County.
The FAA approved the current ALP, submitted by Pitkin County, on May 17, 2016, which showed a path forward to meet the 400’ runway/taxiway separation standard. Pitkin County’s submission of the May 17, 2016, ALP demonstrates that is practical to meet standards at the existing airport site. The FAA will not approve any future ALPs that do not meet the 400’ runway/taxiway separation standard.
