** 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:Building OSP Building #2
Location:Renton, WA
Latitude:47-30-06.93N NAD 83
Longitude:122-12-13.68W
Heights:22 feet site elevation (SE)
156 feet above ground level (AGL)
178 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:
It is required that FAA Form 7460-2, Notice of Actual Construction or Alteration, be e-filed any time the
project is abandoned or:
_____ At least 10 days prior to start of construction (7460-2, Part 1)
__X__ Within 5 days after the construction reaches its greatest height (7460-2, Part 2)
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 and maintained in accordance
with FAA Advisory circular 70/7460-1 L.
The structure considered under this study lies in proximity to an airport and occupants may be subjected to
noise from aircraft operating to and from the airport.
Any height exceeding 156 feet above ground level (178 feet above mean sea level), will result in a substantial
adverse effect and would warrant a Determination of Hazard to Air Navigation.
This determination expires on 08/08/2017 unless:
Page 2 of 4
(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 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 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.
Any failure or malfunction that lasts more than thirty (30) minutes and affects a top light or flashing obstruction
light, regardless of its position, should be reported immediately to (877) 487-6867 so a Notice to Airmen
(NOTAM) can be issued. As soon as the normal operation is restored, notify the same number.
If we can be of further assistance, please contact our office at (202) 267-3215. On any future correspondence
concerning this matter, please refer to Aeronautical Study Number 2015-ANM-3277-OE.
