Okla. Admin. Code § 165:35-25-16
When trimming trees and trimming or removing other vegetation in electric line right-of-way maintenance in urban areas, the utility shall make a reasonable attempt to contact the landowner, customer, or tenant at a minimum of twenty-four (24) hours prior to beginning work on the property. In rural areas the utility shall make a reasonable attempt to contact the landowner, customer or tenant, if known, a reasonable time prior to beginning work on the property. This contact may take the form of a written notice delivered to the landowner's, customer's, or tenant's residence; a telephone call to the landowner, customer, or tenant; or an in-person contact. Reasonable effort shall be made by the utility to accommodate a landowner's, customer's, or tenant's desire to be present when work is done on his or her property. Vegetation management related to emergency repairs is exempt from this notification requirement.
