time before the complete execution of the Purchase Agreement by all parties without any liability
against the City.

The City reserves the right to appoint an inspector or other authorized representative of
the ENGINEER to inspect the gas flare prior to or after shipping, with full power to reject
all materials and workmanship not conforming to the Drawings and Specifications. The
manufacturer shall give the City a minimum notice of five (5) working days before the
completion of the fabricating operations to permit ample time for the inspection of the
gas processing and flare assembly skids.
3.04 TESTING
It is the intent of these specifications that the flare manufacturer supply the flare and
process skid assemblies, assembled and tested at their facilities and supply complete and
working assemblies to the Site. To this extent, the gas processing and flare assembly skid
will be field tested (by the CONTRACTOR) to demonstrate that it meets performance,
capacity, noise, flame height, combustion temperature, skin temperature, and automatic
temperature control requirements. Final acceptance of the equipment is contingent upon
a successful demonstration of the automatic operation of the gas processing and flare
assembly skids through the complete range of its specified design capacity.
A. The manufacturer will be notified 30 days prior to testing and will be invited to
observe the testing. Should the flare fail to meet the specified performance, the
manufacture shall troubleshoot and correct the cause, and perform subsequent
testing at their expense.
12600-16
B. The CONTRACTOR shall be responsible for compliance with the emissions limits
listed herein the Specifications. In addition, the CONTRACTOR shall provide any
necessary logistical support in conjunction with this source test (manlift, etc.), if
required.
C. In the event the source test results revealed non-compliance with the performance
specifications, the CONTRACTOR shall perform any necessary hardware
adjustments to the Flare stack required to meet all performance criteria. These
adjustments shall be conducted at the CONTRACTOR’s expense. The second and
subsequent source tests will be performed at the CONTRACTORS’s expense.
D. Source testing of each flare to demonstrate operation and performance shall be
performed, if required. The Montana Bureau of Air Quality shall determine if the
flare is source tested, after modification of the existing air permit.
3.05 START-UP SUPPORT
The manufacturer shall provide a minimum of three days of on-site start-up services by a
factory field services technician or engineer. One of the three days shall consist of on-
site training by a factory field services technician or engineer. Training shall include
troubleshooting electrical components, input/output cards, etc. The manufacturer shall
provide the cost of an additional optional 2 days, in addition to the three standard days, of
on-site service.
3.06 SPARE PARTS
A. Prior to the completion of the work, the Contractor is required to supply a
complete set of spare parts to be located at the site or as determined by the City,
and a listing of local vendors where spare parts can be obtained. At a minimum
the spare parts shall include the following for new flare station:
Flare station control panel light bulbs for each installed type and size (4 EA)
Flare thermocouple and thermowell (2)
Honeywell UV flame sensor and amplifier card (1 EA)
Spark plug
Damper actuator
Oxygen sensor
Note: (XX) indicates quantity. If no number is indicated, the quantity is one of each
type installed or used in the system.
All spare equipment must be stored in a manner so that it is kept clean and in a like-new
condition, and must not be exposed to weather or UV effects of the sun.
3.07 DRAWINGS AND DATA
Complete as-built fabrication, assembly, support, and installation drawings, showing
fabrication details, detailed specifications, materials used, parts devices and other
12600-17
accessories forming a part of the equipment furnished shall be submitted by the
manufacturer for inclusion in the Operations and Maintenance Manual (O&M).
3.08 ELECTRICAL
A. All electrical work shall conform to the latest edition of the National Electrical
Code, City of Bozeman and State of Montana Code and Regulations, and latest
revisions of the Regulations of the State Fire Marshal.
B. All electrical work and equipment shall be in accordance with the National
Electrical Code for the area classification given. The area within five feet from
blower seal shall be Class 1, Division II, Group D. All other areas will be
unclassified.
C. All conduits and small piping placed on the slab or the skid surface which are in
traffic areas shall have aluminum non-skid floor bridges over them to reduce trip
hazards.
D. Electrical work within the skid shall be constructed by an approved U.L. listed
fabrication shop.
