   CERTIFIED MAIL-RETURN RECEIPT REQUESTED

   December 20, 2010

   Ms. Genevieve Shiroma

   President of the Board

   Sacramento Municipal Utility District

   6201 S. Street

   Sacramento, Ca. 95817-1899

   Re: EB-10-GB-0152

   Dear Ms. Shiroma:

   The Federal Communications Commission has received complaints that
   equipment operated by your utility may be causing harmful radio
   interference to operators in the Amateur Radio Service. The complainants
   are:

   (Name withheld) (Name withheld)

   (Address withheld) (Address withheld)

   (Address withheld) (Address withheld)

   Tel: (Number withheld) Tel: (Number withheld)

   The Commission 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 complainants have attempted unsuccessfully to work through your usual
   complaint resolution process and as a result the matter has been referred
   to our office. The Commission 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 Commission has confidence that most utility companies are able
   to resolve these issues voluntarily, the Commission 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 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 complainants what steps your utility company is taking
   to correct these reported interference problems. The Commission 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 either of
   them by February 25, 2011, 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 1270 Fairfield Road, Gettysburg, Pennsylvania 17325 or via telephone at
   717-338-2577. Thank you for your cooperation.
