STUDY FINDINGS
FAA FAR Part 77 paragraph 9 (FAR 77.9): (Construction or Alteration requiring
notice.) (These are the imaginary surfaces that the FAA has implemented to
provide general criteria for notification purposes.)
This structure does require notification to the FAA.
FAA FAR Part 77 paragraph 17(FAR 77.17): (Standards for Determining
Obstructions.)(These are the imaginary surfaces that the FAA has
implemented to protect aircraft safety. If any of these surfaces are
penetrated, the structure may pose a Hazard to Air Navigation.)
This structure does not exceed these surfaces.
FCC Notice Requirements:
(FCC Rules, Part 17)
This structure does require notification to the FAA or FCC based on these
rules.
FAA EMI:
(The FAA protects certain air navigational aids, radio transmitters, and RADAR
facilities from possible interference. The distance and direction are
dependent on the type of facility being evaluated. Some of these transmission
and receiver facilities are listed in the National Flight Data Center (NFDC)
database.)
This site would not affect any FAA air navigational aids or transmitters.

Military Airspace:
(This would include low level visual and instrument routes along with
operations areas and special use airspace.)
This structure will not affect this airspace.
AM Facilities:
(The FCC protects AM radio stations from possible interference for a distance
of 3.0 km for directional facilities, and 1.0 km for non-directional facilities.
New changes to the FCC critical distances are calculated based on the AM
transmission Movement Method Proof evaluation.)
This site was evaluated against the FCC’s AM antenna database using the
Movement Method proof calculations and no further action is required.
MARKING AND LIGHTING
FAA Advisory Circular 70/7460-1:
Marking and lighting is not required for this structure.
RECOMMENDATIONS
This site was evaluated in accordance with the requirements specified by the
