operations covered by the Standards.

Sec. 210.23  Authorization.

    (a) An inspector is authorized to perform any noise test prescribed 
in the Standards and in the procedures of this part at any time, at any 
appropriate location, and without prior notice to the railroad, for the 
purpose of determining whether railroad equipment is in compliance with 
the Standards.
    (b)(1) An inspector is authorized to request that railroad equipment 
and appropriate railroad personnel be made available for a passby or 
stationary noise emission test, as prescribed in the Standards and in 
the procedures of this part, and to conduct such test, at a reasonable 
time and location, for the purpose of determining whether the railroad 
equipment is in compliance with the Standards.
    (2) If the railroad has the capability to perform an appropriate 
noise emission test, as prescribed in the Standards and in the 
procedures of this part, an inspector is authorized to request that the 
railroad test railroad equipment. The railroad shall perform the 
appropriate test as soon as practicable.
    (3) The request referred to in this paragraph will be in writing, 
will state the grounds upon which the inspector has reason to believe 
that the railroad equipment does not conform to the Standards, and will 
be presented to an appropriate operating official of the railroad.
    (4) Testing or submission for testing is not required if the cause 
of the noise defect is readily apparent and the inspector verifies that 
it is corrected by the replacement of defective components or by 
instituting a normal maintenance or repair procedure.
    (c)(1) An inspector is authorized to inspect or examine a 
locomotive, rail car, or consist of a locomotive and rail cars operated 
by a railroad, or to request that the railroad inspect or examine the 
locomotive, rail car, or consist of a locomotive and rail cars, whenever 
the inspector has reason to believe that it does not conform to the 
requirements of the Standards.
    (2) An inspector may request that a railroad conduct an inspection 
or examination of a locomotive, rail car, or consist of a locomotive and 
rail cars on the basis of an excessive noise emission level measured by 
a passby test. If, after such inspection or examination, no mechanical 
condition that would result in a noise defect can be found and the 
inspector verifies that no such mechanical condition exists, the 
locomotive, rail car, or consist of a locomotive and rail cars may be 
continued in service.
    (3) The requests referred to in this paragraph will be in writing, 
will state the grounds upon which the inspector has reason to believe 
that the locomotive, rail car, or consist of a locomotive and rail cars 
does not conform

[[Page 61]]

to the Standards, and will be presented to an appropriate operating 
official of the railroad.
    (4) The inspection or examination referred to in this paragraph may 
be conducted only at recognized inspection points or scheduled stopping 
points.

Sec. 210.25  Measurement criteria and procedures.

Sec. 201.22 of the Standards. In addition, the following calibration 
procedures shall be used:
    (1)(i) The sound level measurement system including the microphone 
shall be calibrated and appropriately adjusted at one or more nominal 
frequencies in the range from 250 through 1000 Hz at the beginning of 
each series of measurements, at intervals not exceeding 1 (one) hour 
during continual use, and immediately following a measurement indicating 
a violation.
    (ii) The sound level measurement system shall be checked not less 
than once each year by its manufacturer, a representative of its 
manufacturer, or a person of equivalent special competence to verify 
that its accuracy meets the manufacturer's design criteria.
    (2) An acoustical calibrator of the microphone coupler type designed 
for the sound level measurement system in use shall be used to calibrate 
the sound level measurement system in accordance with paragraph 
(b)(1)(i) of this section. The calibration must meet or exceed the 
accuracy requirements specified in section 5.4.1 of the American 
National Standard Institute Standards, ``Method for Measurement of Sound 
Pressure Levels,'' (ANSI S1.13-1971) for field method measurements.
    (c) Acoustical environment, weather conditions, and background noise 
requirements are prescribed in Sec. 201.23 of the Standards. In 
addition, a measurement tolerance of 2 dB(A) for a given measurement 
will be allowed to take into account the effects of the factors listed 
below and the interpretations of these effects by enforcement personnel:
    (1) The common practice of reporting field sound level measurements 
to the nearest whole decibel;
    (2) Variations resulting from commercial instrument tolerances;
    (3) Variations resulting from the topography of the noise 
measurement site;
    (4) Variations resulting from atmospheric conditions such as wind, 
ambient temperature, and atmospheric pressure; and

    (1) Load cell testing in accordance with the criteria prescribed in 
the Standards; or
    (2) Passby testing in accordance with the criteria prescribed in the 
Standards.
    (c) If passby testing is used under paragraph (b)(2) of this 
section, it shall be conducted with the locomotive operating at maximum 
rated horsepower output.
    (d) Each new locomotive certified under this section shall be 
identified by a permanent badge or tag attached in the cab of the 
locomotive near the location of the inspection Form F 6180.49. The badge 
or tag shall state:
    (1) Whether a load cell or passby test was used;
    (2) The date and location of the test; and
    (3) The A-weighted sound level reading in decibels obtained during

     Appendix B to Part 210--Switcher Locomotive Enforcement Policy

    The EPA standards require that the noise emissions from all switcher 
locomotives in a particular facility be less than prescribed levels 
measured at 30 meters, under all operating modes. This requirement is 
deemed to be met unless ``receiving property'' noise due to switcher 
locomotives exceeds 65 dB(A), when measured in accordance with subpart C 
of 40 CFR part 201. The 65 dB(A) receiving property standard is the 
``trigger'' for requiring the 30-meter test of switcher locomotives.

    The purpose underlying FRA's enforcement of the noise standards is 
to reduce the impact of rail operations noise on receiving properties. 
In some instances, measures other than the 30-meter test approach may 
more effectively reduce the noise levels at receiving properties; 
therefore, FRA enforcement efforts will focus on abatement procedures 
that will achieve a reduction of receiving property noise levels to less 
than 65 dB(A).
    For example, a parked, idling locomotive, even if equipped with 
exhaust silencing that meets the stationary locomotive standard (30-
meter test), may cause the receiving property standard to be exceeded if 
located on trackage adjacent to the receiving property. In that case, 
application of the 30-meter test to other switcher locomotives at the 
facility may not serve to reduce the receiving property noise level. On 
the other hand, operational changes by the railroad could significantly 
reduce receiving property noise levels. In such case, FRA would consider 
retesting after abatement measures have been taken. If the receiving 
property noise level is below the trigger and the abatement action is 
adopted, FRA would not make a 30-meter test of the switcher locomotives 
at the facility.
