The FCC has commenced a new rulemaking proceeding to accelerate the deployment of wireless facilities and broadband. The rulemaking may limit local authority to regulate the placement and size of wireless facilities. It also threatens the ability of localities to prevent harm to environmentally and historically sensitive areas. Localities will need to participate in the proceeding to protect their interests from industry efforts to curb local regulatory power. The FCC is considering rules to implement Section 6409, which concerns modifications to existing wireless towers and base stations, and revisions to shot clock rules under Section 332 that impose deadlines for local permitting decisions.
