Sec.  64.4005   Unreasonable terms or conditions on the provision of customer
account information.

   To the extent that a carrier incurs costs associated with providing the
   notifications required by this section, the carrier may recover such costs,
   consistent with federal and state laws, through the filing of tariffs, via
   negotiated agreements, or by other appropriate mechanisms. Any cost recovery
   method must be reasonable and must recover only costs that are associated
   with providing the particular information. The imposition of unreasonable
   terms or conditions on the provision of information required by this section
   may be considered an unreasonable carrier practice under section 201(b) of
   the Communications Act of 1934, as amended, and may subject the carrier to
   appropriate enforcement action.
