Proposed Question Regarding Tree Removal
October 25, 2016

Tree removal in the vicinity of SeaTac International Airport has been proposed in
response to an apparent FAA requirement to ensure "safety." However, the
definition of a safe approach or departure obstacle clearance zone is predicated
on established FAA guidance. For example, approximately one mile west of the
approach end of the runway at Juneau Alaska there is a 140-meter high hill on the
Mendenhall Peninsula. The hill remains; yet safe approach procedures have been
implemented.

QUESTIONS:

1. Has the FAA issued a letter of noncompliance or something to that effect,
which would somehow restrict operations at KSEA?

2. If they did, what specific obstruction(s) is/are not in compliance.

3. Exactly what FAA guidance is cited supporting the non-compliance? Is the
guidance Advisory Circular 150/5300 18B, TERPS, Part 77, etc. or something
else?

4. Are there any man made structures tall enough to penetrate the obstruction
clearance zones? Have they been surveyed? What effect on airport operations do
they have?

5. If accomplished, who has conducted the survey to identify penetrating
obstacles: contractor's name, date of survey, individuals conducting the survey,
etc?

6. Can we see the survey?

7. If obstructions exist, would the FAA accept a waiver or exception to
accommodate the penetrating object? Is there a work-around? Has anyone
applies for alternate means of compliance (AMOC)?

8. Exactly what are the consequences if the trees were not cut down: higher
approach minimums, reduced takeoff weights, or nothing?

9. Is this decision to cut down trees a decision based on economics only?
