   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:

   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
