    The PA as directed by the appropriate state commission point of contact, or by the FCC
point of contact, will reclaim resources in the inventory of pool participants from both
embedded resources as well as thousands-blocks allocated to an SP by the PA.9.2.2
    
    The PA will contact any thousands-block assignee identified as not having returned to
the administrator for reassignment any thousands-block(s) that were:
 a)
    
    allocated, but no longer in use by the assignee(s);b)
    
    allocated for a service no longer offered;c)
    
    allocated, but not placed in service within six months of the original
block effective date returned on the Part 3 and entered onto the BCR/BCD screen in BIRRDS;d)
    
    allocated, but not used in conformance with these guidelines.
 9.2.3
    
    If the PA has not received a Part 4 during the first five months following the original
block effective date returned on the Part 3 and entered onto the BCR/BCD screen in BIRRDS, then
the PA will send, via facsimile/electronic mail, a reminder notice to the block assignee. The
notice will be sent during the first ten calendar days of the sixth month, and will direct the
assignee to do one of the following by the end of the sixth month after the block effective date:
 
    
    If the block is in service, submit a Part 4 to the PA.
    
    If the block is no longer needed or not in service, return the block by

from the PA for a dedicated customer, the SP has the option of submitting the COCAG
Part 4 Form directly to the CO Code Administrator.
    
    If the NXX was requested to replenish the pool, submit the TBPAG Attachment 4: Part 4  Thousands-Block Application
Form for each block that was assigned from the NXX.
    
    If the NXX was requested to establish an LRN, submit the TBPAG Attachment 4: Part 4  Thousands-Block
Application Form for each block that was assigned from the NXX.
