** DETERMINATION OF NO HAZARD TO AIR NAVIGATION **
The Federal Aviation Administration has conducted an aeronautical study under the provisions of 49 U.S.C.,
Section 44718 and if applicable Title 14 of the Code of Federal Regulations, part 77, concerning:
Structure:Antenna Tower Heffernan Hill
Location:Concow, CA
Latitude:39-44-09.09N NAD 83
Longitude:121-29-20.63W
Heights:2514 feet site elevation (SE)
180 feet above ground level (AGL)
2694 feet above mean sea level (AMSL)
This aeronautical study revealed that the structure does not exceed obstruction standards and would not be a
hazard to air navigation provided the following condition(s), if any, is(are) met:
Based on this evaluation, marking and lighting are not necessary for aviation safety. However, if marking/
lighting are accomplished on a voluntary basis, we recommend it be installed in accordance with FAA Advisory
circular 70/7460-1 L Change 2.
This determination expires on 01/17/2022 unless:
(a)the construction is started (not necessarily completed) and FAA Form 7460-2, Notice of Actual
Construction or Alteration, is received by this office.
(b)extended, revised, or terminated by the issuing office.
(c)the construction is subject to the licensing authority of the Federal Communications Commission
(FCC) and an application for a construction permit has been filed, as required by the FCC, within
6 months of the date of this determination. In such case, the determination expires on the date
prescribed by the FCC for completion of construction, or the date the FCC denies the application.
NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DETERMINATION MUST
BE E-FILED AT LEAST 15 DAYS PRIOR TO THE EXPIRATION DATE. AFTER RE-EVALUATION
OF CURRENT OPERATIONS IN THE AREA OF THE STRUCTURE TO DETERMINE THAT NO
SIGNIFICANT AERONAUTICAL CHANGES HAVE OCCURRED, YOUR DETERMINATION MAY BE
ELIGIBLE FOR ONE EXTENSION OF THE EFFECTIVE PERIOD.

This determination is based, in part, on the foregoing description which includes specific coordinates, heights,
frequency(ies) and power. Any changes in coordinates, heights, and frequencies or use of greater power, except
those frequencies specified in the Colo Void Clause Coalition; Antenna System Co-Location; Voluntary Best
Practices, effective 21 Nov 2007, will void this determination. Any future construction or alteration, including
increase to heights, power, or the addition of other transmitters, requires separate notice to the FAA.This
determination includes all previously filed frequencies and power for this structure.
If construction or alteration is dismantled or destroyed, you must submit notice to the FAA within 5 days after
the construction or alteration is dismantled or destroyed.
This determination does include temporary construction equipment such as cranes, derricks, etc., which may be
used during actual construction of the structure. However, this equipment shall not exceed the overall heights as
indicated above. Equipment which has a height greater than the studied structure requires separate notice to the
FAA.
This determination concerns the effect of this structure on the safe and efficient use of navigable airspace
by aircraft and does not relieve the sponsor of compliance responsibilities relating to any law, ordinance, or
regulation of any Federal, State, or local government body.
A copy of this determination will be forwarded to the Federal Communications Commission (FCC) because the
structure is subject to their licensing authority.
