  3. Data Submittal Process 1.Reports will be available to list all pending submittals. 2. Updates and confirmation for in-service dates, will be requested weekly. 3. Status of submittals will be available to ERCOT and submitters. 4. Submitters may query and sort their projects to facilitate close coordination with ERCOT on pending projects. 5.
