The ISO shall use the same methods in communicating the approval or rejection of an Outage request or approval of a request to change an Approved Maintenance Outage to the relevant Participating TO or Participating Generator.
OCP 8	Outage Coordination for New Facilities
OCP 8.1	Coordination by ISO
The procedure to energize and place in service any new or relocated piece of equipment, connected to the ISO Controlled Grid, must be set out by the Participating TO, Participating Generator or Connected Entity in a written procedure and coordinated by the ISO Outage Coordination Office.
OCP 8.2	Types of Work Requiring Coordination
The types of work which the ISO will coordinate under OCP 8 includes any new addition, replacement or modification to the ISO Controlled Grid, including:
(a)	transmission lines forming part of the ISO Controlled Grid;
(b)	equipment including circuit breakers, transformers, disconnects, reactive devices, wave traps, forming part of the ISO Controlled Grid;
(c)	Generating Unit interconnections; and 
(d)	protection and control schemes, including RAS, SCADA, EMS, or AGC.
OCP 8.3	Uncomplicated Work
When line rearrangements and/or station equipment work is uncomplicated and easily understood, the ISO Outage Coordination Office may determine that the work can be accomplished using Outages approved in accordance with OCP 5.  The ISO Outage Coordination Office will make this determination in coordination with the respective requesting Participating TO, Participating Generator or Connected Entity.
OCP 8.4	Special Procedures for More Complex Work
OCP 8.4.1	Responsibility for Preparation
In cases to which OCP 8.3 does not apply, it is the responsibility of the requesting Participating TO, Participating Generator or Connected Entity to prepare a written procedure to enable the ISO to approve Outages in a manner that enables the necessary work to proceed.  The ISO Outage Coordination Office must approve the procedure.
OCP 8.4.2	Information to be Provided to the ISO
The written procedure must be received by the ISO Outage Coordination Office a minimum of four (4) weeks prior to the start of procedure.  Adequate drawings will be attached to the procedure to help clarify the work being performed and the Outages that will be required to complete the work must be specified.  The procedure shall include all of the information referred to in OCP Appendix A.
OCP 8.4.3	Approval of the Procedure
Upon receipt of the procedure referred to in OCP 8.4.2, the ISO Outage Coordination Office will review the procedure and notify the Participating TO, Participating Generator or Connected Entity of any required modifications.  The ISO Outage Coordination Office may, at its discretion, require changes to and more detail to be inserted in the procedure.  The requesting Participating TO, Participating Generator or Connected Entity will consult with other entities likely to be affected and will revise the procedure, following any necessary or appropriate discussions with the ISO to reflect the requirements of the ISO.  Following the ISO approval, an approved copy of the procedure will then be transmitted to the Participating
TO, Participating Generator or Connected Entity and the other entities likely to be affected.
OCP 8.4.4	Changes to Procedure
Once the procedure is approved by the ISO Outage Coordination Office any modifications to the procedure will require the requesting Participating TO, Participating Generator or Connected Entity to notify the ISO Outage Coordination Office with as much lead time as possible of the recommended changes.  The modified procedure will then have to be approved by the ISO Outage Coordination Office to which the provisions of OCP 8.4.3 will apply.
