C.
General standards.
(1)
Closed-loop systems. All geothermal heating/cooling systems
shall be closed-loop systems. No open-loop systems shall be permitted.
(2)
All equipment for the geothermal heating/cooling system shall
be located on the same lot as the principal use.
(3)
All plumbing equipment and connections to geothermal heating/cooling
system equipment shall be placed underground. All other equipment
shall be placed entirely within the primary structure, as conforms
to industry standards.
(4)
Casings. Casings may be necessary to hold the closed-loop geothermal
borehole open during the drilling process. Casings may be left in
the closed-loop borehole at the discretion of the well contractor.
When a casing is used, grouting the annular space is required. Grout
shall be mixed, pumped and placed in accordance with industry standards.
Acceptable grout materials are as follows:
(5)
Closed-loop geothermal boreholes shall be located, drilled and
finished in a manner that will protect the borehole structure from
damage from surface activities or other natural occurrences so that
the quality of local groundwater cannot be affected.
(6)
The geothermal well installation contractor shall be responsible
for insuring that the borehole is drilled in the permitted location.
Deviation from the permitted location must receive prior written approval
from the Borough. The geothermal well installation contractor shall
be responsible for drilling the borehole and the final backfilling
and grouting after the closed-loop pipe loop has been installed.
(7)
All geothermal heating/cooling systems in areas underlain by
carbonate bedrock must be vertical loop systems. If the closed-loop
geothermal borehole penetrates bedrock, it must be grouted from a
depth of 15 feet into the bedrock to the top of the borehole. Outside
carbonate bedrock areas, either vertical or horizontal closed-loop
geothermal heating/cooling systems may be used, subject to the review
and approval of the plans by the Borough.
(8)
No geothermal heating/cooling system shall be connected in any
way to any sanitary or stormwater sewage disposal system.
(9)
The piping for geothermal heating/cooling systems must be made
of polyethylene or polybutylene or a material approved by the Borough
Engineer.
(10)
The pipe loop is to be installed by a geothermal well installation
contractor who is certified in the proper method of heat fusion specified
by the pipe manufacturer. The geothermal well installation contractor
shall be responsible for insuring that the pipe loop is installed
in accordance with the specifications of the geothermal heating/cooling
system manufacturer, the pipe manufacturer, and that the borehole
is properly backfilled. Backfilling shall be according to the specifications
of the geothermal heating/cooling system equipment manufacturer. When
sand is the specified backfill material, the borehole shall be constructed
in the same manner as a water supply well. A casing is required to
be used and the annular space is required to be grouted.
(11)
Only water or fluids conforming to industry standards may be
used as the circulating fluid for geothermal heating/cooling systems,
unless a similar fluid is approved by the Borough Engineer.
(12)
Well installation. The geothermal well installation contractor
shall provide to the Borough before activation of the ground source
heat pump the following:
(a)
Accurate written records and a written geologic log.
(b)
Accurate records with respect to grouting for each well.
(c)
As-built plans and related documentation for each system and
well location. Trace wire shall also be provided to identify the location
of all wells and piping.
(d)
Written documentation of the geothermal heating/cooling system
testing and certification.
(e)
Written plan for the operation of the geothermal heating/cooling
system (which meets the specifications of the manufacturer of the
system equipment).
(13)
Maintenance of geothermal heating/cooling system.
(a)
All geothermal heating/cooling systems shall be properly maintained
in accordance with the manufacturer's specifications and any regulations
of the Pennsylvania Department of Environmental Protection and/or
any federal regulations.
(b)
Any owner of a lot upon which a geothermal heating/cooling system
is installed shall be responsible for maintaining the system.
(c)
If a geothermal heating/cooling system malfunctions, the person
responsible for the maintenance of the system shall take all action
necessary to repair, modify, or alter the system to eliminate the
malfunction within three months of the malfunction.
(d)
Any geothermal heating/cooling system leaks or releases will
be reported by the applicant (and subsequent owners) to the Borough
with 24 hours of the discovery of same, and the applicant (and subsequent
owners) covenants and agrees to take all appropriate action to minimize
any fluid release to the ground and promptly repair any system leak.
(e)
In the event of the proposed discontinuance of the geothermal
heating/cooling system, a system closure plan will be prepared and
submitted to the Borough for its removal.
(f)
If a geothermal heating/cooling system is inoperable for six
consecutive months, the owner shall be notified. Within three months
of receiving the notice, the owner shall either restore the system
to operating condition or remove it, at the owner's expense. The heat
transfer fluid must be removed by a displacement with grout. The top
of the borehole must be uncovered and capped with grout.
