ditional assistance is justified due to the resi-
dence containing any sound insulation treat-
ment or other type of sound proofing material 
previously installed under this subchapter that 
is determined to be eligible pursuant to para-
graph (2); and 
‘‘(B) the residence— 
‘‘(i) falls within the Day Night Level 
(DNL) of 65 to 75 decibel (dB) noise con-
tours, according to the most recent noise 
exposure map (as such term is defined in 
section 150.7 of title 14, Code of Federal

sound insulation treatment were of 
low quality and have deteriorated, 
broken, or otherwise no longer func-
tion as intended; and

the ability to achieve a 5 dB noise reduc-
tion;

gible for waiver under this subsection for repair or 
replacement of sound insulation treatment projects, 
an applicant shall—

‘‘(C) demonstrate that a qualified noise 
auditor, based on an inspection of the residence, 
determined that— 
‘‘(i) the sound insulation treatment 
for which Federal assistance was pre-
viously provided has resulted in structural 
deterioration that was not caused by fail-
ure of the property owner to repair or ade-
quately maintain the residential building or 
through the negligence of the applicant or 
the property owner; and 
‘‘(ii) the condition of the sound insula-
tion treatment described in subparagraph 
(A) is not attributed to actions taken by 
an owner or occupant of the residence.

Notwithstanding any other provision of law, the Sec-
retary shall consider a cost allowable under this sub-
chapter for an airport to conduct periodic surveys of 
properties in which repair and replacement of sound 
insulation treatment was carried out as described in 
paragraph (1) and for which the airport previously 
received Federal assistance or Federally authorized 
airport assistance under this subchapter. The sur-
veys shall be conducted only for those properties for
