    In The Matter Of:
    R80—9
    Proposed Amendment to the Noise Regulations,
    )
    R80—l0
    Rules 101,
    206,
    208 and 209
    )
    PROPOSED RULE.
    SECOND NOTICE.
    ORDER OF THE BOARD
    (by 3. Anderson):
    On December
    4,
    1980,
    the Board ordered publication of the
    First Notice of rules to limit the sound emitted by the explosive
    blasting activities of the coal mining and quarrying industries.
    These proposed rules were published in the Environmental Register
    #229, December 18,
    1980 and in the Illinois Register, Vol
    5,
    pp.
    5—11, January
    2,
    1981.
    In response to public comments, the Board
    has eliminated the expiration date of the rules,
    and has redefined
    daytime hours as being after sunrise and before sunset,
    rather
    than being from 8:00 a.m.
    to 5:00 p.m.
    No other
    substantive
    revisions have been made.
    The Board directs that second notice
    of the proposed rules be submitted to the Joint Committee on
    Administrative Rules, which read as follows:
    Chapter
    8:
    Noise
    Rule 101:
    Definitions
    Impulsive sound:
    either
    a single pressure peak or a
    single burst
    (multiple pressure peaks)
    for a duration
    usually less than one second.
    Examples of impulsive
    sound sources are a drop forge hammer and explosive
    blasting.
    Slow Dynamic Characteristic:
    The dynamic character-
    istic specified as “Slow”
    in ANSI document S1.4—1971
    “Specification for Sound Level Meters”,
    or subsequent
    revisions.
    C—weighted Sound Level:
    In decibels,
    a frequency
    weighted sound pressure
    level,
    determined by the use
    of the metering characteristic and C—weighted network
    specified in ANSI document S1,4—1971 “Specification
    for Sound Level Meters”,
    or subsequent revisions.
    Fast Dynamic Characteristic:
    The dynamic characteristic
    specified as
    “Fast”
    in ANSI S1.4—1971
    “Specification
    for Sound Level Meters”,
    or subsequent revisions.
