Re: EB-10-GB-0084
Dear Mr. (name withheld):
The Federal Communications Commission has received complaints that a water
pump being operated on your property at your residence may be causing
harmful radio interference to AM broadcast reception and operators in the
Amateur Radio Service. The complainant is:
(Name withheld)
(Address withheld)
(Address withheld)
Tel: (Number withheld)
The Commission has the responsibility to require that such problems be
rectified within a reasonable time if the interference is caused by faulty
equipment. Under FCC rules, equipment such as a water pump is classified
as an "incidental radiator." This term is used to describe equipment that
does not intentionally generate any radio-frequency energy, but that may
create such energy as an incidental part of its intended operation.
Associated pump electronics and control circuitry may also be classified
as "unintentional radiators." These devices intentionally generate
radio-frequency energy but do not intentionally radiate it.
To help you better understand your responsibilities under Commission
rules, here are the most important rules relating to radio and television
interference from incidental and unintentional radiators:
Title 47, CFR Section 15.5 General conditions of operation.
(b) Operation of an intentional, unintentional, or incidental radiator is
subject to the conditions that no harmful interference is caused and that
interference must be accepted that may be caused by the operation of an
authorized radio station, by another intentional or unintentional
radiator, by industrial, scientific and medical (ISM) equipment, or by an
incidental radiator.
(c) The operator of the radio frequency device shall be required to cease
operating the device upon notification by a Commission representative that
the device is causing harmful interference. Operation shall not resume
until the condition causing the harmful interference has been corrected.
Title 47, CFR Section 15.13 Incidental radiators.
Manufacturers of these devices shall employ good engineering practices to
minimize the risk of harmful interference.
Title 47, CFR Section 15.15 General technical requirements.
(c) Parties responsible for equipment compliance should note that the
limits specified in this part will not prevent harmful interference under
all circumstances. Since the operators of Part 15 devices are required to
cease operation should harmful interference occur to authorized users of
the radio frequency spectrum, the parties responsible for equipment
compliance are encouraged to employ the minimum field strength necessary
for communications, to provide greater attenuation of unwanted emissions
than required by these regulations, and to advise the user as to how to
resolve harmful interference problems (for example, see Sec. 15.105(b)).
The complainant has attempted unsuccessfully to resolve this problem with
your water pump and as a result the matter has been referred to our
office. The FCC prefers that those responsible for the proper operation of
equipment assume their responsibilities fairly. This means that you should
resolve the interference caused by the water pump and make necessary
corrections within a reasonable time.
While the Commission has confidence that most people are able to resolve
these issues voluntarily, the Commission wants to make you aware that this
unresolved problem may be a violation of FCC rules and could result in a
monetary forfeiture (fine) for each occurrence. At this stage, the
Commission encourages the parties to resolve this problem without
Commission intervention; but if necessary to facilitate resolution, the
Commission may investigate possible rules violations and address
appropriate remedies.
The American Radio Relay League, a national organization of Amateur Radio
operators, may be able to offer help and guidance about radio interference
that involves Amateur Radio operators.

Please advise the complainant and this office what steps you are taking to
correct this reported interference problem. The Commission expects that
most cases can be resolved within 30 days of the time they are first
reported. If you are unable to resolve this within 30 days, please advise
this office about the nature of the problem, the steps you are taking to
resolve it and the estimated time in which those steps can be
accomplished.
If you have any questions about this matter, please contact me in writing
at: 1279 Fairfield Road, Gettysburg, PA 17325 or via telephone at
