A relief obligation would be issued to all parties contributing to the loading.

5. 5 Free Template from www.brainybetty.com 5 Parallel Flow Visualization (continued) NERC is responsible for making the changes to the IDC. NERC is targeting changes to the IDC by November 1, 2010. (Functional Specification is expected to be approved by the IDCWG by February 5, 2010.) WEQ BPS will establish methodology for assigning the GTL flows into the appropriate priority buckets (e.g., firm or non-firm) that will be uploaded to the IDC. The NERC ORS is looking at a 12-18 month parallel test to analyze the results of the IDC changes. The WEQ BPS is currently identifying the general categories of data that would be uploaded to the IDC. Upcoming BPS Meetings: –February 23-24, 2010 –March 17-18, 2010 –April 1, 2010 Unknown what impact RM10-9-000 may have on this Annual Plan item.
