Okla. Stat. tit. 17 § 139.303
The Oklahoma Legislature finds that Electric Providers, their broadband subsidiaries, Telecommunications Providers and Approved Broadband Providers shall be permitted to use existing electric utility easements owned, held or otherwise used by that Electric Provider to provide or expand access to Broadband Services. The installation and operation of Broadband Services within the existing electric utility easements are merely changes in the manner or degree of the granted use as appropriate to accommodate a new technology and, absent any applicable express prohibition contained in the instrument conveying or granting such easements, shall be deemed as a matter of law to be a permitted use within the scope of every Electric Provider's existing electric utility easement. Subject to compliance with any express prohibitions in an Electric Provider's easement, and in compliance with this act, the Electric Provider, its broadband subsidiary, Telecommunications Provider and an Approved Broadband Provider may use an existing electric utility easement to install, maintain, lease and operate Broadband Services. An Approved Broadband Provider, an Electric Provider's broadband subsidiary, or Telecommunications Provider shall attempt to provide notice to the property owner.
