If a submitter requests urgent status, the complete PRR is forwarded to the e- mail distribution list of the PRS. The Standing Representatives of PRS are requested to submit a vote on whether the PRR should receive urgent status.

If a submitter requests Urgent status for a PRR, or upon a valid motion in a regularly scheduled meeting of the PRS and the PRS determines that such PRR: (1)requires immediate attention from TAC due to (a) serious concerns about ERCOT System reliability or market operations under the unmodified language or (b) the crucial nature of settlement activity conducted pursuant to any settlement formula; and (2)is of a nature that allows for rapid implementation without negative consequence to the reliability and integrity of the ERCOT System or market operations; then
