    ORDER OF THE BOARD (by B. Forcade):
    This matter arises on the Board’s own motion. The Board
    today opens an inquiry docket to consider proposed changes to the
    Board’s noise regulations.
    Since their adoption in 1985, the only amendment to the
    Board’s noise regulations was the specification of one hour as
    the basic period of measurement for property line noise sources.
    changes in instrumentation capabilities and developments in the
    field have taken place which prompt the Board to review the noise
    regulations. In 1990, a research study was sponsored jointly by
    the Board and the Department of Energy and Natural Resources
    (“Department”) to examine the adequacy of existing noise
    regulations to appropriately encompass the various types of
    discontinuous noise, and specifically impulse noise. This
    resulted in a report authored by Dr. Paul D. Schomer entitled,
    “Impulse Noise Study, ILENR/RE—EA-90/16, December 1990.” As a
    follow up to this study, Dr. Schoxaer did additional work
    sponsored by the Department to describe and develop a systematic
    set of procedures for noise measurements with particular focus on
    the 1-hour sound equivalent level (1-hr Leg) measurement that is
    specified in the Board’s regulation for property line noise
    sources. This second report by Dr. Schoiner is entitled,
    “Proposed Revisions to Property—Line—Noise—Source Measurement
    Procedures, ILENR/RE-EA-91-16, June 1991.”
    As a consequence of the inquiry docket opened today, the
    Board intends to hold two days of inquiry hearings. The primary
    focus of the inquiry hearings are the proposed changes to the
    Board’s noise regulations under Subpart H and amendments to the
    measurement procedures included in the reports by Dr. Schomer.
    Dr. Schomer and Greg Zak from the Illinois Environmental
    Protection Agency (Agency) are scheduled to present testimony
    dealing with the proposed changes. The Board anticipates that
    proposed language containing the amendments will be available for
    review prior to the inquiry hearing. Further, the Board
    126—713
    2
    anticipates that the amendments will be proposed by the Agency
    for adoption by the Board as a First Notice proposal very soon
    after the inquiry hearing. The Board also welcomes testimony,
    studies, reports anó comments on any of these matters as well as
    on any related matters from all interested parties and
    participants at this hearing. In particular, the Board is
    interested in receiving information on:
    (i)
    under
    what
    circumstances and noise characteristics, the 1—hr L
    q
    is or is
    not an appropriate measurement descriptor of noise revels from a
    source and (ii) whether a measurement period other than 1-hr can
    be spec~~fiedif certain criteria are met and what those criteria
    are. The Board specifically requests information and comments on
    the need for and advisability of setting noise standards and
    measurement procedures for recreational marine boats, sometimes
    termed “cigarette boats.”
    The Board will set November 25 and 2, 1991 for hearing.
    Diane O’Neill will act as hearing officer at the hearings.
    Any questions or comments concerning this matter should be
    directed to her.
    IT IS SO ORDERED.
