§  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.
