FCC Enforcement Letters
October 2, 2003
The Honorable Marc McDougal, Mayor
City of Lubbock
Box 2000
Lubbock, TX 79408
Dear Mayor McDougal:
The Federal Communications Commission notified the City of Lubbock on February
10, 1998 that FCC regulations regarding incidental radiator devices cover
electric utility lines. This information was sent by Robert Darling of the FCC
Dallas Field Office to Assistant City Attorney Matt Wade. The correspondence
was the result of complaints of harmful radio interference possibly caused by
equipment operated by Lubbock Power and Light.
For your reference, the interference in this case has been reported by an
operator in the Amateur Radio Service. The complainant was:
Bryan S Edwards, W5KFT
3801 68th Street
Lubbock, TX 79413
According to Mr. Edwards, the harmful interference he reported remains
unresolved. Please be advised the FCC has the responsibility to require that
utility companies rectify such problems within a reasonable time if the
interference is caused by faulty power utility equipment. Under FCC rules, most
power-line and related equipment 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.
To help you better understand your responsibilities under FCC rules, here are
the most important rules relating to radio and television interference from
incidental 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 work through your usual
complaint resolution process and as a result the matter has been referred to
our office. The FCC prefers that those responsible for the proper operation of
power lines assume their responsibilities fairly. This means that your utility
company should locate the source of any interference caused by its equipment
and make necessary corrections within a reasonable time.
While the FCC has confidence that most utility companies are able to resolve
these issues voluntarily, the FCC wants to make your office aware that this
unresolved problem may be a violation of FCC rules and could result in a
monetary forfeiture for each occurrence. At this stage, the FCC encourages the
parties to resolve this problem without FCC intervention, but if necessary to
facilitate resolution, the FCC 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 what steps your utility company is taking to
correct this interference problem. The FCC expects that most cases can be
resolved within 60 days of the time they are first reported to the utility
company. If you are unable to resolve this by December 15, 2003, 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 at 717-338-2502.
