General Limitations and Exemptions 1.1 Crossing locations are only to be used to transport a vehicle or equipment through a power line ROW. No work is allowed in an ROW without a specific work permit plus authorization from FHPS. 1.2 Vehicles and equipment traveling along roadways paralleling and within a FHPS ROW do not need authorization from FHPS unless the vehicle or equipment will intrude into the restricted area around the power lines. 1.3 Any work utilizing articulating equipment in a roadway paralleling and within a FHPS ROW requires authorization from FHPS. 1.4 Installation of a goal post will be utilized at all crossing locations through a power line ROW denoting the maximum height of a vehicle or equipment as shown on the approved crossing sign (refer to Appendix A, Figure 2). Refer to FHOS-TD0016A, Installation Of Goal Posts Right Of Way (ROW) Crossing 1.5 Location of goal posts will be located on entry to ROW as defined in step 5.1 of this document or as stipulated on authorization issued by FHPS.
