§ 77.37 

(2) Limitations necessary to mini-

mize potential problems, such as the 
use of temporary construction equip-
ment. 

(3) Supplemental notice require-

ments, when required. 

(4) Marking and lighting rec-

ommendations, as appropriate. 

(e) The FAA will issue a Determina-

tion of No Hazard to Air Navigation 
when a proposed structure does not ex-
ceed any of the obstruction standards 
and would not be a hazard to air navi-
gation. 

§ 77.33

Effective period of determina-

tions. 

(a) The effective date of a determina-

tion not subject to discretionary re-
view under 77.37(b) is the date of 
issuance. The effective date of all other 
determinations for a proposed or exist-
ing structure is 40 days from the date 
of issuance, provided a valid petition 
for review has not been received by the 
FAA. If a valid petition for review is 
filed, the determination will not be-
come final, pending disposition of the 
petition. 

(b) Unless extended, revised, or ter-

minated, each Determination of No 
Hazard to Air Navigation issued under 
this subpart expires 18 months after 
the effective date of the determination, 
or on the date the proposed construc-
tion or alteration is abandoned, which-
ever is earlier. 

(c) A Determination of Hazard to Air 

Navigation has no expiration date.

21, 2010, as amended by Amdt. 77–13–A, 76 FR 
2802, Jan. 18, 2011] 

§ 77.35

Extensions, terminations, revi-

sions and corrections. 

(a) You may petition the FAA official 

that issued the Determination of No 
Hazard to Air Navigation to revise or 
reconsider the determination based on 
new facts or to extend the effective pe-
riod of the determination, provided 
that: 

(1) Actual structural work of the pro-

posed construction or alteration, such 
as the laying of a foundation, but not 
including excavation, has not been 
started; and 

(2) The petition is submitted at least 

15 days before the expiration date of 

the Determination of No Hazard to Air 
Navigation. 

(b) A Determination of No Hazard to 

Air Navigation issued for those con-
struction or alteration proposals not 
requiring an FCC construction permit 
may be extended by the FAA one time 
for a period not to exceed 18 months. 

(c) A Determination of No Hazard to 

Air Navigation issued for a proposal re-
quiring an FCC construction permit 
may be granted extensions for up to 18 
months, provided that: 

(1) You submit evidence that an ap-

plication for a construction permit/li-
cense was filed with the FCC for the as-
sociated site within 6 months of 
issuance of the determination; and 

(2) You submit evidence that addi-

tional time is warranted because of 
FCC requirements; and 

(3) Where the FCC issues a construc-

tion permit, a final Determination of 
No Hazard to Air Navigation is effec-
tive until the date prescribed by the 
FCC for completion of the construc-
tion. If an extension of the original 
FCC completion date is needed, an ex-
tension of the FAA determination 
must be requested from the Obstruc-
tion Evaluation Service (OES). 

(4) If the Commission refuses to issue 

a construction permit, the final deter-
mination expires on the date of its re-
fusal.

ment on the proposal but were not 
given an opportunity to state it, you

tionary review of a determination, re-
vision, or extension of a determination

temporary structure, marking and 
lighting recommendation, or when a 
proposed structure or alteration does

tained in subpart C of this part.
