(A) As used in this section, CAR COUPLING SOUND means a sound which is heard and identified by the observer as that of a car coupling impact, and that causes a sound level meter indicator to register an increase of at least ten decibels above the level observed immediately before hearing the sound.
(B) No railroad shall conduct car coupling operations within the town that exceed an adjusted average maximum A-weighted sound level of 92 decibels at any receiving property measurement location, when measured with fast meter response in accordance with 40 C.F.R. part 201, subpart C; except, such coupling will be found in compliance with this standard and the railroad will be considered in compliance, if the railroad demonstrates that the standard is exceeded at the receiving property measurement locations (where the standard was previously exceeded) when cars representative of those found to exceed the standard are coupled at similar locations at coupling speeds of eight mph or less.
(C) Any railroad that engages in a car coupling operation that results in excessive noise as described in division (B) above is responsible for compliance with said part. Such railroad shall modify the car coupling procedure to bring it within the prescribed noise limits.
