Section 2. Initial Processing/Verification
6-2-1. VERIFICATION/E-FILING
a. The OES shall verify each obstruction
evaluation case to ensure that the submitted site
elevation and coordinates appear to be correct and
that all necessary information has been included.
Verification shall include, as a minimum, the
following actions:
1. Compare the submitted site depiction to the
submitted coordinates when plotted.
2. Compare the submitted site elevation to the
ground contour elevations in the area of the submitted
coordinates when plotted.
3. If a survey is submitted, compare the
information contained on the survey, with the
submitted information and the site as plotted.
4. If the submission involves an existing
structure, compare the submitted information to the
digital obstacle file, with the previous aeronautical
study (if any), and possibly the FCC tower
registration information.
5. Ensure that the submission provides a
complete description and clearly explains the reason
for submission. The submission should include
sufficient information to allow each division/service
area office to accomplish its specialized portion of the
obstruction evaluation.
6. If the submission involves a structure that
would normally radiate frequencies, ensure that the
frequencies and effective radiated power are
included.
7. If the submission involves a structure over
200 feet AGL, ensure marking and/or lighting
preferences are part of the submission. Sponsors shall
be required to specifically request the type of marking
and/or lighting they desire when submitting FAA
Form 7460-1. They should be encouraged to become
familiar with the different type of lighting systems
available. The sponsor should obtain information
about these systems from the manufacturers. The
sponsor can then determine which system best meets
his/her needs based on purchase, installation, and
maintenance costs. The FAA will consider the
sponsor's desired marking and/or lighting system
when conducting the aeronautical study.
b. If the submission contains errors, discrepancies, or lack of information, the OES shall request
resolution by the sponsor and/or the sponsor's
representative. If the sponsor does not resolve the
issues within 30 days of the written request, the OES
may terminate the aeronautical study.
c. If the submission passes verification and there
are no unresolved issues, initiate evaluation by other
divisions by changing the status in the OE/AAA
automation program to "WRK."
NOTE-
It is imperative that all data in the automated OE case file
is reviewed and verified for accuracy before proceeding
to "Division/Service Area Office Coordination." Any
correction or change to the heights and/or coordinates
after the divisions/service area offices begin evaluation
shall require initiating a new aeronautical study.
6-2-2. VERIFICATION/PAPER-FILING
a. Prior to assigning an aeronautical study into the
OE/AAA automation program, review the submission for completeness. The following information
should be considered:
1. Ground elevation of the site (site elevation).
2. Above ground elevation of the structure
(AGL).
3. Latitude and longitude of the structure.
4. A 7.5-Minute U.S.G.S. Topographic Map
(Quadrangle Chart) depicting the site of the structure.
b. If the submission package contains all of the
required information, assign an aeronautical study
number and initiate an obstruction evaluation study.
Exceptions may be made for emergency situations in
accordance with 77.17(d).
c. If the submission package does not contain the
required information, the entire package may be
returned to the sponsor with a clear explanation and
a request for the sponsor to provide the information
necessary to initiate the study.
d. For submission packages pertaining to structures that may be time critical, an effort should be
made to obtain the required information by
telephone. Information received by telephone
conversation should be added to case notes. If
written confirmation is received from the sponsor,
it should be faxed/scanned into the file.
6-2-3. DIVISION COORDINATION
Each division described in paragraph
5-2-2
shall evaluate all notices of proposed construction or
alteration received regardless of whether notice was
required under part 77, except as follows:
NOTE-
For the purpose of division/service area office
coordination, Frequency Management (FM) will be
considered separately in addition to Technical Operations
Services. It should also be noted that FM responds
separately.
a. Side Mounted Non-Microwave Antennas.
Airports, Technical Operations Services, Airway
Facilities and the military normally are not required
to review OE cases that involve the addition of
antennas to a previously studied structure that does
not increase in overall height of the structure. FM will
continue to evaluate these cases. The FAA must have
previously studied the structure and the data of the
present case and it must exactly match the data of the
previously studied case.
b. Side Mounted Microwave Dishes. Airports,
Flight Standards, and the military normally shall not
be required to review OE cases that involve the
addition of microwave dishes to a structure that does
not increase in overall height. FM will continue to
evaluate these cases. The FAA must have previously
studied the structure and the data of the present case
and it must exactly match the data of the previously
studied case.
c. Marking and Lighting Changes. Airports,
Flight Standards, Flight Procedures, FM, Technical
Operations Services, and the military normally are
not required to review OE cases which involve only
marking and lighting changes. The FAA must have
previously studied the structure and the data of the
present case and it must exactly match the data of the
prior case.
d. Temporary Structures. Airports, Flight Standards, FM, and the military normally shall not be
required to review OE cases which involve temporary
structures of a 6 month or less duration. All
appropriate divisions/service area offices shall
review temporary structures of a longer duration.
e. Flight Procedures normally shall not be
required to review OE cases that are beyond 14 NM
from the airport reference point of the nearest
public-use or military airport and the height of the
structure is not more than 200 feet above ground
level.
f. Airports normally shall not be required to
review OE cases that are beyond 3 NM from the
airport reference point of the nearest public-use or
military airport.
g. Flight Standards shall review OE cases that are
circularized for public comment.
h. FM normally shall only be required to review
OE cases, that involve transmitting frequencies.
6-2-4. ADDITIONAL COORDINATION
Air traffic may request any division to review an OE
case on a case-by-case basis. For instance, Flight
Standards should be requested to review a marking
and lighting change, the military should be requested
to review a temporary structure if the closest airport
is a military base, or FM should be requested to
review a temporary structure if it radiates a frequency.
