8 ERP Levels TYPE-1 Emergency Event / Catastrophic The damage severity impacts the entire system such that restoration activities may require up to seven days or more once it is safe to begin restoration activities. Typically > 15% (>150,000) customer interruptions. Typically > 7,000 Lines of Trouble at Peak Anticipated to occur between 1 and 4 times in a ten-year period. TYPE-2 Emergency Event / Serious The damage severity within a specific region or spread across the system is such that restoration activities are generally accomplished within a 96-hour period once it is safe to begin restoration activities. Typically 5 to 17% (50,000 to 187,000) customer interruptions. Typically 3,000 to 10,000 Lines of Trouble at Peak. This type of event is anticipated to occur between 2 and 4 times in a five-year period. TYPE-3 Emergency Event / Moderate The damage severity within a specific district or region(s) is such that restoration activities are generally accomplished within a 48-hour period. Typically 2 to 7% (20,000 to 77,000) customer interruptions. Typically 1,800 to 3000 Lines of Trouble at peak. This type of event generally occurs between 1 and 5 times per year.

17 ERP Priorities: OHM Spill Response Priority # 1 - Public & Crew Safety Priority # 2 - Restore Power ( Get The Lights On ) Priority # 3 - Environmental Impact Cleanup / Remediation

18 Typical OHM OHM Spill Response 1. Mineral Oil Dielectric Fluid Non-PCB MODF 2. MODF PCB > 50 ppm 3. Hydraulic & Brake Fluid 4. Gasoline 5. Diesel Fuel 6. Sulfuric Acid (Battery Acid) 7. Mercury Historically, 95% of all event OHM spills 8. Ethylene Glycol consist of Non-PCB MODF from overhead electrical equipment damaged by high winds, trees, snow plows and other vehicle hits.

19 OHM Spill Response Response Priorities (Triage) Priority # 1 Spills that impede Fire, Police, and EMS Priority # 2 Spills near Public Drinking Water Supplies, PCB, Surface Water, Wetlands or Customer Property Priority # 3 Spills adjacent to roadways or on NSTAR property

20 OHM Response Assess, Notification & Cleanup 1) De-energized / Safety 2) Assess - PCB? - Storm Drains / Surface Water? - Soil / Pavement / Wetlands? 3) Agency Notification 4) Cleanup & Restore 5) Closure (LRA / RAO / RBC / SIP)
