ORDER OF THE BOARD

(by I. Goodman):

For reasons set out in the accompanying

Opjfl±Oflr the Board

incorporates the following language into its Chapter

8:

Noise

P01 lution.

RULE

101:

DEFINITIONS

A-Weighted Sound Level:

dB(A), in decibels,

a frequency

weiahted

sound pressure level, determined by the use of

the

rneterinq

characteristics and A-weighted network specified in

ANSI

§t~4

-

1971

(R.

1976)

“Specification for Sound Level Meters”

and the

latest revisions thereof.

dB(A).

See “A—Weighted Sound Level”~~

Fast

Dynaruic Characteristic:

The dynamic characteristic specified

as fast in ANSI S1.4—1971

(R.

1976)

“Specification

for

~ov~r4

Level

Meters” and the latest revision thereof.

Leg~:

Equivalent continuous

sound pressure level

in decibels~ ten

times

the logarithm to the base ten of the ratio of

a

time-mean-

~~are

sound pressure to the square of reference

sound~pressure.

The reference pressure is 20 micronewtons ier square

meter.

RULE 205 ~96:

IMPULSIVE SOUND

Except as elsewhere in this Part

2 provided, no

person shall cause

or allow the emission of impulsive sound from any

property*_line~~

noise—source located on any Class

A,

B, or

C

land to

any receiving

Class

A or B ?

land which exceeds the allowable

A-w~hted

sound

levels, measured with fast dynamic characteristic,

specified

in Table

5, when measured at any point within such

receiving

Class

land, provided, however,

that no measurement

of

sound

le’iels shall be made less than 25 feet from such

property-~line-

IMPACT FORGING OPERATIONS

(a)

For purposes of this rule only the following

are

appiicah1e~

(1)

Daytime hours shall mean any continuous

16

hour~~iod

between 6:00 a.m. and 11:00 p.m.

local

time~and

(2)

Nighttime hours shall mean those

8 hours

between

10:00 p.m. and 7:00 a.m. which are not part

of

the

continuous Daytime hours.

(3)

The reference time for Leq,

as defined

in

Rule 101,

is

one hour.

on which construction began after the effective datéo~

this rule.

No impact fo~gingoperation shall cause or allow

the

emission of impulsive sound to any receiving
