20 5,000 Customers Impacted

21 Hurricane Irene 2011

22 Oradell District Headquarters

23 NJ River Flooding After Hurricane Irene

24 Severe Flooding in Northern NJ 34,000 Customers Restored

25 Flood Damage - Little Falls, NJ

26 Create Flood Zone Polygons Capture Street Addresses in Affected Areas

27 Risk Assessment High Risk - areas where we have actively shut down the gas distribution system following foundation movement and building collapse from severe flooding. Flowing water or deep saturation in poor soil conditions causes undermining of building foundations. Moderate Risk areas where rising water has a minimal potential of entering the gas distribution system or damaging company equipment. Meter sets are most affected. Low Risk areas with limited flooding, the threat of foundation damage is low and no company equipment is typically damaged by water.

28 Capture Real Time Restoration Data Tools and resources to accurately track customer status

29 Proactive Recommendations Install Excess Flow Valves - 2,000 EFV s per year in moderate risk flood areas (HP services only) Develop Overheated Boiler Policy Ensure that District Regulator breather piping and vents are adequately piped Ensure that District Regulator vaults & vent posts are adequately sealed Upgrade Mobile Command Vehicle

62 Determining Material Needs Replace Submerged Meters & Regulators Gas Meters: Estimate # of gas meter changes within perimeter of flood regions Regulators: Estimate # of I&C and Residential Regulators within Flood Regions Identify Pressure Areas affected Identify Large Volume Meter Sizes inside perimeter Consider Possible Site Rebuilds & Replacement Part Kits

63 Safety Tailboard Preparation

64 Gas Restoration Safety & Procedures Review Service Technicians receive initial & daily Safety Tailboard reviews covering specific subjects: Flood Safety Mold Awareness Training Mercury Regulator Identification A&I Notifications (Gas Turn-ons) Warning Tag (Violation) Procedures Overheated Boiler Response Flood Restoration Procedures Gas Restoration Documentation

65 Safety in Flooded Areas Wear hard hats, safety glasses, vest, gloves and other PPE when working in flooded areas. Expect floors and stairs to be oily and slippery. When ascending or descending stairs, hold the railing and step to one side. Do not go into basements where standing water, raw sewage or obvious electric hazards may exist. Treat all wiring, even telephone and cable, as live. Electricity and Water Do Not Mix - high potential for electric shock. Do not attempt to reconnect the electric supply to an appliance that has been exposed to water damage. Tetanus booster shot needed if not received within 10 years. Follow OSHA website to determine if additional shots needed (Hepatitis).

66 Tailboard Review Job Expectations

67 Gas Restoration Expectations for OEMs, Municipalities & Towns Damage Assessment: Track flooding conditions Assess Damage - bridge crossings, regulator stations, exposed main & other Company facilities Perimeter of Flooded Area: Estimate the number of customers affected by flood waters Field Command Centers: Secure suitable locations for restoration work Support severely damaged areas Work closely with local authorities (Police & FD) Establish ongoing communications mechanisms

68 OEM Employees Keeping Customers Safe in Hoboken

69 Partnership with OEMs Gas Restoration Process Join forces with Municipal Inspectors to establish a safe plan for assessing damaged structures and turning off gas facilities at the same time. Restoration activities will not begin until flood water has been cleared. Safely turn off gas facilities to ensure that flood water has not caused damage to utility/customer equipment and gas piping. Prior to the utility restoring gas service, Municipal Inspectors may expect to provide an inspection approval (where required) to determine that: Customer basements are cleared of water Electric facilities (electric panel, meter box) are verified for safety Following inspector approval, customers are expected to contact utility to restore gas after their home/building passes an inspection.

70 Post-Flood Inspections NJDCA supports the process shared between PSE&G and municipal inspectors for performing post-flood inspections and gas appliance restorations simultaneously. NJDCA provides inspector resources to assist municipalities not having enough staff to support postflood inspections.

71 Municipal Inspectors Partner with PSE&G

72 Gas Restoration Requirements When restoring gas to customers, PSE&G will establish that customer gas piping is not leaking, and may replace meters, service regulators and possibly regulator vent piping if they have been exposed to water. PSE&G will not restore gas to water heaters if controls have been affected by flood waters. Flooded units must be replaced. PSE&G s restoration policy for gas fired furnaces & boilers requires that all gas controls, control system parts, and electrical parts that have been underwater must be replaced before the unit may be safely operated. Replacement of the entire unit may be required on a case-by-case basis.

73 Explosion/Injury Risks Boilers & Furnaces Heating controls exposed to flood water can fail after being dried and placed back in operation. Any controls exposed to flood water must always be replaced.

74 What is an Overheated Boiler? Overheated Boiler : Heating unit reaches an exceedingly high temperature and pressure, and will not shut off. This condition, a.k.a. Runaway Boiler, is considered unsafe and very hazardous to emergency responders and building occupants. This condition is primarily caused by coincidental failures of redundant safety controls that maintain safe temperature, pressure, gas supply, and water supply. Previous boiler failure incidents occurred when safety controls failed to operate as designed due to mechanical failure (i.e., aquastat shorting out, damaged wiring, or failed gas valve) or human intervention.

75 Service Technician Performs Safety Inspection on Customer Boiler

76 Provide restoration update for community Describe steps required to restore customers OEM Coordination Town Hall Meetings

77 Exit Strategy for Customer Support Work with OEMs, towns and municipalities to plan an Exit Strategy after the majority of customers have been restored and local Command Centers have been discontinued. Exit Strategy includes: Establishing contact information and designated responsibilities to support customers who have had restoration delayed due to repairs or other circumstances.

78 Hoboken Mayor & Gov Christie Discuss Restoration Plans

79 Restoration Meetings with Hoboken Mayor Zimmer

80 Restoration Strategy in Field Command Center

81 Key Lessons Learned Prepare & share gas restoration expectation documents with OEMs and customers. For badly stricken areas, set restoration expectations early with Mayor and Code Official Staff. Some municipalities provide a block-by-block grid map, which enhanced the efficiency of the inspections significantly, especially in Hoboken. Following past practice & lessons learned, PSE&G has a policy for changing out gas meters and regulators touched by water either on the inside or outside. Expand the use social media to communicate system status and important safety messages preceding major weather events.

82 Key Lessons Learned Work with municipalities to post a link to PSE&G s website to share important safety and flood safety restoration messages. Continue outreach efforts to establish restoration protocol with municipal code officials. Promote the use of mobile hot spots in those areas impacted by the storm to aid in electronic information gathering and communications. Following SS Sandy, PSE&G and NGRID successfully tested ULC Robotics DWX-200 Dewatering Camera prototype. This apparatus allows utilities to make a single tap hole to find and siphon off water up to 200 feet away in a live gas main.
