   (1) Channel availability in the General Access Pool in any of the urbanized
   areas referred to in the table depends on whether that channel is presently
   assigned to one of the following categories of users:

   (i) Public safety (as defined in  Sec. 90.20(a));

   (ii) Power and telephone maintenance licensees (as defined in  Sec. 90.7);

   (iii) Special industrial licensees (as defined in  Sec. 90.7);

   (iv) Business licensees (as defined in  Sec. 90.35(a));

   (v) Petroleum, forest products, and manufacturers licensees (as defined in
    Sec. 90.7);

   (vi) Railroad, motor carrier, and automobile emergency licensees (as defined
   in  Sec. 90.7); and

   (vii) Taxicab licensees (as defined in  Sec. 90.7).

   (2) If assigned, subsequent authorizations will only be granted to users
   from the same category. If unassigned, or should a channel subsequently
   become unassigned, it will be treated as available in the General Access
   Pool.

   (3) Normally, each channel should be substantially loaded in accordance with
   the standards set out in  Sec. 90.313.

   (4) The following frequencies will be authorized a maximum bandwidth of 6
   kHz.
