Field Verification (Scrubbing)

1. PSNH Retirees - Knowledge of Distribution System

2. AWC schedule - Geographic locations

3. Identified gaps - Data sources

4. Electrical connectivity issues

5. Markups - Preparation for source data submission

6. Open Points - Underground Residential Development

7. Detailed Sector Cabinets

8. Results - Vendor questions reduced
