Sec. 90.727   Extended implementation schedules for Phase I licensees.

    Except for nationwide and commercial systems, a period of up to 
three (3) years may be authorized for constructing and placing a system 
in operation if:
    (a) The applicant submits justification for an extended 
implementation period. The justification must include reasons for 
requiring an extended construction period, the proposed construction 
schedule (with milestones), and must show either that:
    (1) The proposed system will serve a large fleet of mobile units and 
will involve a multi-year cycle for its planning, approval, funding, 
purchase, and construction; or
    (2) The proposed system will require longer than 8 months to place 
in operation because of its purpose, size, or complexity; or
    (3) The proposed system is to be part of a coordinated or integrated 
area-wide system which will require more than 8 months to construct; or
    (4) The applicant is a local governmental agency and demonstrates 
that the government involved is required by law to follow a multi-year 
cycle for planning, approval, funding, and purchasing the proposed 
system.
    (b) Authorizations under this section are conditioned upon the 
licensee's compliance with the submitted extended implementation 
schedule. Failure to meet the schedule will result in loss of 
authorizations for facilities not constructed.
