47 CFR 1.1313 – Objections
(a) In the case of an application to which section 309(b) of the Communications Act applies, objections based on environmental considerations shall be filed electronically as petitions to deny. If the interested person is unable to file electronically or if filing electronically would be unreasonably burdensome, such person may submit the petition by mail, with a request for waiver under § 1.1304(b).
(b) Informal objections which are based on environmental considerations must be filed electronically prior to grant of the construction permit, or prior to authorization for facilities that do not require construction permits, or pursuant to the applicable rules governing services subject to lotteries. If the interested person is unable to file electronically or if filing electronically would be unreasonably burdensome, such person may submit the objection by mail, with a request for waiver under § 1.1304(b).
