§ 151.85 

use being made of a hangar governs, 
unless there is definite information re-
garding its future use. In the case of an 
apron area being built for future hang-
ars, it should be shown that early

ties. 

(c) Appendix E of this part sets forth 

typical eligible and ineligible items of 
apron paving. 

§ 151.85 Special treatment areas. 

The following special treatment for 

areas adjacent to pavement is eligible 
for inclusion in a project in cases 
where, due to the operation of turbojet 
powered aircraft, it may be necessary 
to treat those areas adjacent to run-
way ends, holding aprons, and taxiways 
to prevent erosion from the blast ef-
fects of the turbojet: 

(a) Runway ends—a stabilized area 

the width of the runway and extending 
100 to 150 feet from the end of the run-
way. 

(b) Holding aprons—a stabilized area 

up to 50 feet from the edge of the pave-
ment. 

(c) Taxiway intersections—a sta-

bilized area 25 feet on each side of the 
taxiway and extending 300 feet from 
the intersection. 

(d) Taxiway (continuous movement 

of aircraft)—dense turf 25 feet on each 
side of the taxiway, or in a geographic 
area where dense turf cannot be estab-
lished, stabilization. 

§ 151.86 Lighting and electrical work: 

General. 

(a) The installing of lighting facili-

ties and related electrical work, as pro-
vided in § 151.87, is eligible for inclusion 
in a project only if the Administrator 
determines, for the particular airport 
involved, that they are needed to en-
sure— 

(1) Its safe and efficient use by air-

craft under § 151.13; or 

(2) Its continued operation and ade-

quate maintenance, and it has a large 
enough volume (actual or potential) of 
night operations. 

(b) Before the Administrator makes a 

grant offer to the sponsor of a project 
that includes installing lighting facili-
ties and related electrical work under 

paragraph (a) of this section, the spon-
sor must— 

(1) Provide in the project for remov-

ing, relocating, or adequately marking 
and lighting, each obstruction in the 
approach and turning zones, as pro-
vided in § 151.91(a); 

(2) Acknowledge its awareness of the 

cost of operating and maintaining air-
port lighting; and 

(3) Agree to operate the airport light-

ing installed— 

(i) Throughout each night of the 

year; or 

(ii) According to a satisfactory plan 

of operation, submitted under para-
graph (c) of this section. 

(c) The sponsor of a project that in-

cludes installing airport lighting and 
related electrical work, under para-
graph (a) of this section, may— 

(1) Submit to the Administrator a 

proposed plan of operation of the air-
port lighting installed for periods less 
than throughout each night of the 
year; 

(2) Specify, in the proposed plan, the 

times when the airport lighting in-
stalled will be operated; and 

(3) Satisfy the Administrator that 

the proposed plan provides for safety in 
air commerce, and justifies the invest-
ment of Program funds. 

(d) Paragraph (b)(3) of this section 

also applies to each sponsor of a 
project that includes installing airport 
lighting and related electrical work if 
that sponsor has not entered into a 
grant agreement for the project before 
September 5, 1968. 

(e) If it agrees to comply with para-

graph (b)(3) of this section, the sponsor 
of a project that includes installing 
airport lighting facilities and related 
electrical work that has entered into a 
grant agreement for that project before 
September 5, 1968, may— 

(1) Surrender its air navigation cer-

tificate authorizing operation of a 
‘‘true light’’ issued before that date; or 

(2) Terminate its application for au-

thority to operate a ‘‘true light’’ made 
before that date.
