Related Files

Status:
The Board of Trustees adopted the interpretation on February 7, 2013. The interpretation was filed with the appropriate regulatory agency April 12, 2013.
 

Background:
This interpretation request was submitted to NERC as a process to address the Federal Energy Regulatory Commission's concern about the study of single point of failure in protection systems documented in Order No. 754.

Interpretation Process (excerpt):
In accordance with the Reliability Standards Development Procedure, the first formal comment period shall be 30-days long. If the drafting team makes substantive revisions to the interpretation following the initial formal comment period, then the interpretation shall undergo another quality review before it is posted for its second formal comment period. The second formal comment period shall have a 45-day duration and shall start after the drafting team has posted its consideration of stakeholder comments and any conforming changes to the associated standard.

Formation of a ballot pool shall take place during the first 30 days of the 45-day formal comment period, and the initial ballot of the interpretation shall take place during the last 10 days of that formal comment period. The interpretation drafting team shall consider and respond to all comments submitted during the formal comment period at the same time and in the same manner as specified for addressing comments submitted with ballots.

If the interpretation is approved by its ballot pool, then the interpretation will be appended to the standard and will become effective when adopted by the NERC Board of Trustees and approved by the applicable regulatory authorities.  The interpretation will remain appended to the standard until the standard is revised through the normal standards development process.  When the standard is revised, the clarifications provided by the interpretation will be incorporated into the revised standard.
