52 Pa. Code § 27.5
Certificates of public convenience approving applications will be issued subject to the limitations and conditions that the Commission may deem proper. Whenever the Commission approves an application, a compliance order will issue notifying the applicant that it shall file with the Commission within 30 days of receipt of the notice, a certificate of insurance or other security, as required by § 27.8(Reserved), together with a tariff setting forth the proposed rates and charges as required by § 27.12 (relating to time and rate schedules). This compliance order does not grant the applicant the right to operate and a certificate of public convenience, permitting the applicant to operate, will not issue until insurance tariff and other filing requirements have been complied with. If a common carrier shall fail to meet the requirements of the compliance order within the 30-day period in this section, the Commission may rescind approval and dismiss the application.
