As used in this article, the following terms shall be interpreted or defined as follows:
AMBIENT NOISE LEVELThe all-encompassing noise level associated with a given environment, being a composite of sounds from all sources at the location constituting the normal or existing level of environmental noise at a given location without extreme atmospheric conditions, such as wind greater than three meters per second or precipitation, and then adjusting the noise level to eliminate any noise associated with then existing development of facilities.
A. The noise level shall be established based on a test performed during a continuous seventy-two-hour time span which shall include at least one twenty-four-hour reading during either a Saturday or Sunday. The testing shall be done by a qualified noise control engineer or other qualified person approved by the Township and shall be in accordance with specifications ANSI S12.18-1994 Method II and ANSI SI.4-1971. The Township reserves the right to hire a third-party consultant to witness testing and review the results. The third-party costs will be deducted from the facility operator's escrow deposit. The sound level meters used shall meet the American Standard Institute's standard for a Type I sound level meter.
APPROVEDAccepted, sanctioned or endorsed by appropriate Township, county, Commonwealth of Pennsylvania, or federal government bodies.
DECIBEL (DB)A unit for measuring the intensity of a sound/noise; equal to 10 times the logarithm to the base 10 of the ratio of the measured sound pressure, squared to a reference pressure of 20 micropascals.
NATURAL GAS COMPRESSOR STATIONA facility designed and constructed to compress natural gas that originates from an oil and gas well or collection of such wells operating as a midstream facility for delivery of oil and gas to a transmission pipeline, distribution pipeline, natural gas processing plant, or underground storage field, including one or more natural gas compressors, associated buildings, pipes, valves, tanks and other equipment.
NATURAL GAS PROCESSING PLANTA facility that is not a natural gas compressor station that is designed and constructed to remove materials such as ethane, propane, butane, and other constituents or similar substances from natural gas to allow such natural gas to be of such quality as is required or appropriate for transmission or distribution to commercial markets but not including facilities or equipment that are/is designed and constructed primarily to remove water, water vapor, oil or naturally occurring liquids from natural gas, which includes "dew point control facilities."
OIL AND GAS DEVELOPMENT or DEVELOPMENTThe process of perforating the earth's surface and rock layers to extract fossil fuels, natural gas or oil for energy production, and all associated equipment, structures and construction at the drilling site including the well pad, access roads, hydraulic fracturing, production, pipelines, tanks, meters, and temporary work crew and supervisor trailers for exploration and production at a single well pad, including multiple wells at a single well pad, and all subsequent site reclamation activities which follow the production phase.
OPERATORAny person, partnership, company, corporation, and its subcontractors, and agents who operate or seek to operate a natural gas compressor station.
PROTECTED STRUCTUREAny occupied residence, commercial business, school, religious institution or other public building located within 500 feet of a natural gas compressor station that may be impacted by noise, emissions, light, or other negative attributes not limited to natural gas compressor stations and associated with activities as defined herein.
SETBACKSThe required minimum horizontal distance between the building line and the related front, side, or rear property line, or along a private or public street, in which no building or accessory structure may be located above ground, except as otherwise provided in this article (excludes nominal roof overhangs, chimneys, unenclosed porches and stoops, and porch or entrance roofs not exceeding six feet in depth).
SITEWith the exception of the definition for "oil and gas development or development" as set forth above, as used in this article the term "site" is defined as a natural gas compressor station, as defined above, and the property surrounding a natural gas compressor station upon which any equipment, fixtures, storage, access roads, driveways, maintenance, and activities associated with the natural gas compressor station are located.
