This bill streamlines how state and local governments review requests from wireless and telecommunications companies to modify existing infrastructure like cell towers and antenna facilities. Under current law, these government reviews can take months and require extensive documentation; the bill requires governments to approve or deny such modification requests within 60 days and automatically deems requests approved if the government fails to respond within that timeframe. The bill also limits what documentation governments can require from companies, restricting requests to information specifically needed to determine if a modification qualifies under the law, and adds protections for modifications that improve public safety and network resiliency such as backup power systems. Companies can sue in federal court for violations, with courts required to expedite these cases. The Federal Communications Commission must issue final regulations within 180 days of the law's enactment, and the changes apply to all requests submitted after the bill becomes law.
