Status
MISO is seeking interpretation of NERC reliability standards TPL-002 and TPL-003 Requirements 1.3.2. and 1.3.12.

The drafting team is reviewing the ballot comments for the revised interpretation.

Purpose/Industry Need
In accordance with the Reliability Standards Development Procedure, the interpretation must be posted for a 30-day pre-ballot review, and then balloted.  There is no public comment period for an interpretation.  Balloting will be conducted following the same method used for balloting standards.  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.
