Section 2. Initial Processing/Verification
6-2-1. VERIFICATION/E-FILING
a. The OEG must
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 must 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 must 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 OEG must
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
OEG 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 must 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 must 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 must 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 Team, 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 must not
be required to review OE cases which involve temporary structures of a 6 month
or less duration. All appropriate divisions/service area offices must review
temporary structures of a longer duration.
e. Flight
Procedures Team normally must 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 must 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 must review OE cases that are circularized for public comment.
h. FM normally
must 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 may be
requested to review a marking and lighting change, the DOD may be requested to
review a temporary structure if the closest airport is a DOD base, or FM may be
requested to review a temporary structure if it radiates a frequency.
