Water Act (35 P.S. § 721.1 et seq.).
STANDING-COLUMN GEOTHERMAL SYSTEM
A type of open-loop geothermal heating and/or cooling system
that circulates groundwater from a water well through a water-source
heat pump and returns the discharge water from the water-source heat
pump to the same water well it was pumped from. The water withdrawal

chapter.
During all activities and/or phases related to the construction
of any well, including, but not limited to, site preparation, drilling/boring

well construction, including, but not limited to, soil, rock fragments
or pulverized rock, brines, fluids and/or water. The containment means
shall be in accordance/compliance with all federal, state, local,
PA DEP or York County Soil Conservation Office regulations and/or
guidelines.
All sections and provisions of this chapter shall apply to any and/or all phases or processes included in the construction of all wells developed for the purpose of utilization of geothermal resources, exclusive of being tested for potability, unless the provisions set forth in Chapter
490 of this Code require more-stringent requirements, in which case those requirements shall be followed. Unless otherwise specifically provided for in Chapter

E. The application for a well permit shall be acted upon by the Township's
duly authorized representative within 15 days of the time he/she receives
the application. Such action shall be either an approval or denial,
in which case a written report explaining the denial is submitted
to the applicant along with the original application.
F. The Township makes no claim(s) to the construction of the well, work
done by the driller, the success of finding a water source, the quality
or quantity of any water found, or future productivity of the well;
furthermore, disclaiming any responsibility of the well drilling process
or events/occurrences resulting from the well drilling process.
All well drillers shall, upon completion of the drilling and
construction of any well, file a report on a form supplied by or approved
by the Township. Said report shall be filed with the Township's
representative before requesting, or concurrent with the request for,
an approval of operation for the said well. The report shall be signed
by the well driller. [NOTE: The signature of the well driller found
on the well driller's report shall secure as certification and
testimony to the truthfulness of said report and verification that
compliance with this chapter and all other regulations, federal, state,
or local, which might apply have been met.] The said report shall
contain the following pertinent information:
J. Yield in gallons per minute.
K. Pump output in gallons per minute.
No responsibility or liability for the construction of any well/water
supply nor guaranties of the quantity or quality of the water from
that source shall be deemed to be assumed or accepted by Hellam Township
or its officers, agents, representatives or employees by virtue of
the terms of this chapter or otherwise.
The provisions of this chapter shall be severable. If any provision,
sentence, clause, section or part of this chapter, or the application
of any provision hereof, is for any reason found to be unconstitutional,
illegal or invalid, such unconstitutionality, illegality or invalidity
shall not affect or impair any of the remaining provisions, sentences,
clauses, sections or parts of this chapter. It is hereby declared
as the intent of the Township that this chapter would have been enacted
had such unconstitutional, illegal or invalid provision, sentence,
clause, section or part hereof not been included.
To the extent that any provisions of this chapter conflict with
provisions of other chapters or ordinances which may be in effect,
the other chapter or ordinance provisions shall remain in full force
and effect to the extent that those provisions are more restrictive.
If there is any conflict between any of the provisions of this chapter,
the more restrictive shall apply.
