No heavy equipment, including but not limited to trucks, tractors, trailers, bulldozers, bobcat tractors, trenchers, compressors and hoists shall be allowed inside the critical root zone of any protected tree on any compressor site without the specific approval of the City Forester. This requirement shall supersede other landscaping requirements, except for the tree reservation and/or planting percentage requirements in Section 66-162.
f. All equipment or buildings associated with the operation of the compressor located in or within one thousand (1,000) feet of residentially used property or from the public right-of-way shall be screened from public view by appropriate landscaping, berming, structure or wall constructed of metal, masonry or other structurally sound material as approved by the Director of Planning and Development or his/her designee that significantly screens the equipment and is painted in a non-contrasting soft earth tone color to match the nearby surroundings as nearly as possible.
g. Secondary containment shall be required around all compressor stations. All secondary containment must meet the requirements of subsection (A)(32) of Section 66-161, "technical regulations."
h. Exhaust from any internal combustion engine or compressor, stationary or mounted on wheels, used in connection with the drilling of any well or for use on any production equipment shall not be discharged into the open air unless it is equipped with an exhaust muffler or mufflers or an exhaust muffler box constructed of non-combustible materials sufficient to suppress noise and disruptive vibrations and prevent the escape of noxious oil and gases, fumes or ignited carbon or soot.
i. All facilities shall be inspected by the Fire Marshal for compliance with relative fire codes and the Oil and Gas Inspector prior to operation of the compressor.
3. Line compressors.
a. Line compressors shall be permitted only in "AG" agricultural district, "I" restricted light industrial, "I2" light industrial, "I3" heavy industrial districts.
b. All line compressors shall be set back a minimum of one thousand (1,000) feet from any protected use and six hundred sixty (660) feet from all public buildings not necessary to the operation of the compressor. The setback from protected uses may be reduced to
six hundred sixty (660) feet provided the line compressor is fully enclosed. Equipment and buildings not part of the operation of the compressor shall be set back a minimum of six hundred sixty (660) feet from the protected use, public building or habitable structure or one hundred (100) feet from the property line, whichever is greater.
c. Line compressors located in "AG" agricultural, "I" restricted light industrial, "I2" light industrial, "I3" heavy industrial districts shall be required to meet the following standards:
(1) Line compressor stations located in "AG" agricultural, "I" restricted light industrial, "I2" light industrial, "I3" heavy industrial zoning districts shall meet the applicable noise standards for that zoning classification as set out in subsection (1)(a) above. Landscaping, buffering or acoustical structures shall be required as required by this section and as required by the zoning regulations for the applicable zoning district.
(2) No sound blankets shall be allowed.
(3) All acoustical structures must be constructed of permanent material constructed of metal, masonry or other structurally sound material as approved by the Director of Planning and Development that significantly screens the equipment is a non-contrasting soft earth tone color to match the nearby surroundings as nearly as possible and meets all applicable building and fire codes.
(4) All facilities shall be inspected by the Fire Marshal for compliance with relative fire codes, and the Oil and Gas Inspector prior to operation of the compressor.
(5) Exhaust from any internal combustion engine or compressor, stationary or mounted on wheels shall not be discharged into the open air unless it is equipped with an exhaust muffler, or mufflers or an exhaust muffler box constructed of noncombustible materials sufficient to suppress noise and disruptive vibrations and prevent the escape of noxious oil and gases, fumes or ignited carbon or soot.
d. Line compressors shall be permitted in all other zoning districts only by a special exception granted by the City Council, which has been reviewed by the Planning Commission. In order to grant a special exception, the line compressor must meet the minimum
standards of "I1" restricted light industrial district and a site plat must be submitted and approved by the board. The Zoning Board of Adjustment shall grant the application only when the board determines that the location of the compressor is clearly defined on the site plan by the applicant; and the exception will be compatible with the existing uses and the development of adjacent properties either as filed, or subject to such requirements as the board finds necessary to protect and maintain the stability of adjacent properties.
e. All compressor and associated equipment and buildings shall be enclosed by a six (6) foot security fence constructed per Section 66-162 "fences and landscaping" of this article.
f. One three (3) inch caliper tree shall be planted every forty (40) linear feet along the property line abutting a public right-of-way.
