This legislation aims to streamline the consideration of requests by state and local governments for modifications to existing wireless facilities. It amends current law to mandate that these governments approve any eligible facilities request for modifications that do not substantially alter the physical dimensions of an existing wireless tower, base station, or support structure. A key provision introduces a 60-day "deemed approved" timeframe , meaning if a government fails to approve or properly deny a request within this period, the request is automatically considered approved. The bill clarifies the process for determining when a request is considered submitted and outlines specific conditions for tolling the 60-day review period , such as for incomplete submissions, with strict requirements for notification. It also limits the documentation state and local governments can require, ensuring it is reasonably related to determining eligibility and publicly identified. To ensure compliance, the legislation grants requesting parties the ability to bring an action in federal district court for expedited review . Significantly, the bill expands the definition of an "eligible facilities request" beyond just collocation, removal, or replacement of transmission equipment. It now includes modifications that improve the resiliency of wireless infrastructure and provide a direct benefit to public safety , such as backup power, hardening, or more reliable connection capabilities. The Federal Communications Commission is directed to issue final rules to implement these amendments within 180 days of the bill's enactment, applying to all eligible requests submitted thereafter.
