GENERAL RULE D - 20 NOISE LEVEL REQUIREMENTS
FOR NON-WELLHEAD COMPRESSOR FACILITIES
a) Applicability:
1) The provisions of this rule apply to all
non-wellhead compressor facilities or stations used in the production process,
as defined in Ark Code Ann. §
15-71-110 as amended, or whose owner is not
affiliated with an Arkansas natural gas public utility and the majority owner
is either a production company or an affiliate of a production
company.
2) All non-wellhead
compressor facilities in operation as of the initial effective date of this
rule shall be in compliance with the provisions of this rule by July 1,
2012.
3) All non-wellhead
compressor facilities that become operational after the initial effective date
of this rule shall be in compliance with the provisions of the rule within one
year of commencing compressing operations.
b) Definitions:
1) "ANSI" means the American National
Standards Institute, and any reference to an ANSI publication shall refer to
the version that was in effect as of January 1, 2011, unless otherwise
stated.
2) "Leq" means the
Equivalent Continuous Sound Level which is the notional sound pressure level
which, if maintained constant over a given time, delivers the same amount of
acoustic energy at some point as the time-varying sound pressure level would
deliver at the same point and over the same period of time.
3) "Noise sensitive area" means a building
with an established mailing address that is being utilized as a private
residence,, school, hospital, church, nursing home, or other building of a type
that is regularly used for overnight accommodation.
4) "Non-well head compressor facility or
station" means any compressor facility or station used for the purpose of
compressing natural gas for pipeline transportation. This shall not include a
compressor facility or station located on a well pad for the purpose of
enhancing production of natural gas from the well or wells located on the
pad.
5) "Normal full-load operating
conditions" means the normal operating condition of the non-wellhead compressor
facility or station, excluding accidents, emergency situations, other
unforeseen temporary operational deviations, including without limitation the
performance of maintenance or construction activities.
c) The noise levels for a non-wellhead
compressor facility or station during normal full-load operating conditions
shall not exceed 55 dB(A) Leq, as measured from the exterior of the nearest
noise sensitive area existing at the time of commencement of initial
construction of the non-wellhead compressor facility or station.
d) Noise levels shall be measured as follows:
1) By utilizing a Type 1 sound level meter,
as defined in ANSI S1.4, set for A-weighting per ANSI S1.11, and slow meter
response.
2) Sound level
measurements shall be in substantial compliance with standard environmental
acoustical measurement practices as outlined in ANSI S 12.9.
3) The Leq contribution due to a non-wellhead
compressor facility or station shall be determined using short-term sound level
averages taken during periods with minimal audible intrusion from extraneous
sources other than the non-wellhead compressor facility or station under test.
The following extraneous noise shall be excluded from the measurements to the
fullest extent possible:
a) Wind;
b) Vehicular Traffic;
c) Residential heating, ventilating, and air
conditioning;
d) Aircraft
over-flights;
e) Bird
sounds;
f) Insect sounds; and
g) Other noise generating
equipment unrelated to the non-wellhead compressor facility or
station.
e)
Any owner or operator of a non-well head compressor facility or station found
to be in violation of the provisions of this rule shall pursue with reasonable
diligence a remedy to correct the violation. Any violation shall be considered
an "operational" violation in accordance with General Rule A-5.
