House Bill No. 3763
EXPLANATORY NOTE

There is no law which prescribes a uniform system for determining noise impact at
airports taking into account the characteristics of an area, including its proximity to an airport
and its nor-aircraft background noise. This is important to protect the public against
significant disturbances in human activities such as sleep and rest.

This bill prescribes aviation noise limits, provides for its management and reduction
especially in the surrounding residential areas, and provides for a staged plan which involves
zoning, land use planning and relocation.

Thus, immediate passage of this bill is earnestly sought.

AN ACT
PROVIDING FOR AVIATION NOISE MANAGEMENT AND REDUCTION IN RESIDENTIAL
AREAS

Be jt enacted by the Senate and the House of Representatives of the Philippines in
Congress assembled.

SECTION 1. Short Title. - This Act shail be known as the ‘Aviation Noise Limit Act.

SEC. 2. Declaration of Policy - The State shall protect public health by determining
noise impact at residential areas near airports and by establishing programs for the
management of noise levels. The State shall aiso ensure the constitutionally protected right
of quiet enjoyment of private property.

SEC. 3. Definition of Terms. - For the purposes of this Act, the following definitions
shall apply:

(1) Airspace traffic change - a change in aircraft flight paths, operating procedures
nature of aircraft. and quantity of aircraft traffic which is applicable in normal

circumstances.

(2) Average sound level - the level in decibels of the mean square, A weighted sound
pressure during a specified period, with reference to the square of the standard
reference sound pressure of 20 micropascals

(3) Background sound level - hourly average sound level in decibels, measured at a site
representative of a relatively quiet residential location within an area (with aircraft
noise contributions excluded).

(4) Day-night average sound level - hour average sound level in decibels. for the period
from midnight to midnight, obtained after the addition of 10 decibels to sound levels
during nighttime hours.

(5) Nighttime hours - periods between midnight and 7:00 a.m and between 10:00 pm
and midnight local time.

(6) Normal circumstances - all circumstances other than unusually adverse weather and
emergency circumstances.

(7) Single event maximum sound level - the level in decibels, of the maximum A
weighted sound pressure during an aircraft over flight obtained using a standard
sound jevel meter under a siow response setting


(8) Vicinity of an airport - the geographic area surrounding an airport established before
the effectivity of this Act described nominally as follows

(a) The area extending in all directions a distance of 1.5 miles from each
runway established before such date of effectivity
(b) The rectangular area defined by drawing a straight center line a

distance of 4 miles from the end of each runway established before
such date of the effectivity in the direction of heaviest traffic and
extending 1.5 miles perpendicular from the center line on each side of
such runway.

SEC. 4. Aviation Noise Limits. - The Air Transportation Office of the Department of
Transportation and Communications shail develop a medium-term pian to reduce by at least
seventy-five percent (75%) the number of individuals residing in residential areas in the
vicinity of an airport who are exposed to a yearly day-night average sound level of sixty (60)
decibels or above. In developing such pian, the Air Transportation Office shall consider
various methods for aviation noise reduction, including soundproofing. relocation incentives.
use of quieter aircraft, operations restrictions and revision of air routes.

As part of the plan to be developed pursuant to the preceding paragraph, the Air
Transportation Office shall make recommendations on actions and policy changes on the
part of departments and agencies of the government which could assist in meeting the
objective described in paragraph 1 of this section.

SEC. 5. Management and Reduction of Aviation Noise in other Areas. -
Beginning on the date of the effectivity of this Act, the Air Transportation Office may make an
airspace traffic change only if the change will not result in an increase in aviation noise in
Violation of the next succeeding section

SEC 6 Requirements. - Non-compliance with any of the following requirements,
which apply only to residential areas that are not in the vicinity of an airport. shall be
considered a violation of this Act:

(a) Hourly Average Sound Level - The hourly average sound level, with combined
aviation and non-aviation sources. over any one (1) hour period may not exceed six
(6) decibels above the background sound level for such one ( 1} hour period.

(b) Single Event Maximum Sound Level - Under normal circumstances. the single event
maximum sound level -

(i) May not exceed seventy (70) decibels:

(ii) during nighttime hours, may not exceed fifty-five (55) decibels; and

(iii) may not be more than twenty (20) decibels above the background sound
level for the one (1) hour period in which the event occurs.

The requirements of this paragraph shall be considered to have been met
if there are no more than three (3) violations of the limits contained in this
subparagraph in a 24-hour period

(c) Day-Night Average Sound Level - If the day-night average sound ievel, with
combined aviation and non-aviation sources, exceeds forty-five (45) decibels, then
aviation activity may not contribute more than three (3) decibels to such sound level

SEC. 7. Determination of Vicinity of Airport. ~ if the location of the airport is
substantially different from the geographic areas as defined by this Act, an airport operator.


may, on or before the 180" day following the effectivity of this Act. transmit to the Air
Transportation Office for approval, alternative boundaries of the vicinity of the airport which
conform to the ground noise distribution of the airport, except that the geographic area
enclosed by such alternative bounderies may not include an area with @ day-night average
sound level of less than sixty (60) decibels for the one (1) year period ending on the date of
the effectivity of this Act

In the event that an airspace traffic change or other action makes it unfeasible or
impracticable to meet the sound level limits prescribed by this Act within a residential area
then such area may be added to the area considered to be in the vicinity of the airport upon
acquisition of the property or by acquisition of easements of the property by the airport
operator.

Not later than one (1) year after the date of the effectivity of this Act. the Air
Transportation Office through the Department of Transportation and Communications shall
transmit to Congress a report containing the plan to be developed and a description of
actions taken with respect to airspace changes together with recommendations for
appropriate administrative and legislative actions.

SEC. 8. Responsibility of the Secretary of Transportation and Communications.
- In complying with this Act, the Secretary of Department of Transportation and
Communications shall assume responsibility for all non-military aviation activity, within end
outside controlled airspace. and shall regulate such activity to ensure compliance with the
requirements of this Act.

SEC. 9. Separability Clause. - If any provision or part hereof is held invalid or
unconstitutional, the remainder of the law or the provision not otherwise affected shall
remain valid and subsisting
