Section 90.155(b) provides that a period no longer than 12 months may be granted to local government entities to place their stations in operation on a case-by-case basis upon a showing of need. This rule provides flexibility to state and local governments. An application for an extension of time to commence service may be made on FCC Form 601. Extensions of time must be filed prior to the expiration of the construction period and will only be granted if the licensee shows that failure to commence service is due to causes beyond its control. Section 90.155(d), requires Location and Monitoring Service (LMS) licensees in the market-licensed multilateration LMS services to file a map showing compliance with the coverage requirements.
