Sec. 24.203  Construction requirements.

    (a) Licensees of 30 MHz blocks must serve with a signal level 
sufficient to provide adequate service to at least one-third of the 
population in their licensed area within five years of being licensed 
and two-thirds of the population in their licensed area within 10 years 
of being licensed. Licensees may choose to define population using the 
1990 census or the 2000 census. Failure by any licensee to meet these 
requirements will result in forfeiture or non-renewal of the license and 
the licensee will be ineligible to regain it.
    (b) Licensees of 10 MHz blocks must serve with a signal level 
sufficient to provide adequate service to at least one-quarter of the 
population in their licensed area within five years of being licensed, 
or make a showing of substantial service in their licensed area within 
five years of being licensed. Population is defined as the 1990 
population census. Licensees may elect to use the 2000 population census 
to determine the five-year construction requirement. Failure by any 
licensee to meet these requirements will result in forfeiture of the 
license and the licensee will be ineligible to regain it.
    (c) Licensees must file maps and other supporting documents showing 
compliance with the respective construction requirements within the 
appropriate five- and ten-year benchmarks of the date of their initial 
licenses.
