PURPOSE AND REQUIREMENTS

Emergency response planning is an essential part of managing a drinking water system to maintain safe and reliable drinking water. An emergency plan helps to establish a protocol for the management and staff of a water system to follow during an emergency, and helps a water system reduce its vulnerability to emergencies. New Hampshire Administrative Rule, Env‐Dw 503.21 Emergency Plans for Community Water Systems, requires community public water systems to have a formal emergency plan. Emergency plans for community systems must be reviewed annually by the water system and an updated plan must be submitted to the New Hampshire Department of Environmental Services (NHDES) at least every six years. Additionally, the plan will be subject to review during sanitary surveys and lack of one will be considered a significant deficiency.

SECTION 4. EMERGENCY NOTIFICATION PROCEDURES

Include a detailed description on how this system would implement emergency notification, including a Boil Order or Do Not Drink Order, to the following contacts: NHDES, local officials, water system customers, including any privately owned redistribution systems (PORS) or consecutive systems, and the general public.

Please note NHDES Drinking Water and Groundwater Bureau must be notified within 24 hours of the following:

Actual or suspected tampering, sabotage, security breach, or any suspicious incident at the water system;

Damage to or depletion of the source of the supply or water system facilities which impairs the quality or sufficiency of the supply; or

Interruption of service of a pressure zone or the entire water system due to an extended power outage, line break, or other cause.

SECTION 4A. BOIL ORDERS/DO NOT DRINK ORDERS

Include the names of who will make the decision to issue a Boil Order or Do Not Drink Order when NHDES Drinking Water and Groundwater Bureau staff is unavailable, how such an order will be prepared and printed, and who is in charge of disseminating such orders or other emergency notices. Please note that only NHDES can lift a boil order notice.

Boil Water Order

1. Should the finished water from the Arthur Rollins Water Treatment Plant (ARWTP), The Lee Well or in the distribution system show it is contaminated with e‐coli or fecal bacteria, a boil water order will be issued within 24 hours of its discovery. After the order has been released the NH DES must be notified.

2. Authorization to release a boil order will come from the UNH Director of Energy & Utilities, Durham Town Engineer or higher. The operational staff will not make any notification unless instructed to do

so. Two forms of public notification are required. Due to the serious implications the radio and television stations should be the first to be notified to broadcast the order. Newspapers should also be notified to print the order until the boil order has been rescinded.

3. Operational staff will identify the cause of the problem by sampling in the area of the positive sample/samples. Once the area and cause are identified, corrective measures will immediately be implemented.

4. The boil order will remain in effect until two consecutive samples have negative results and the NHDES notifies the system it may rescind the boil order.

Do Not Use Order

1. This is the most serious of all public notifications. This occurs when the water is not safe to use for any purpose or there is no water to supply.

2. This would occur when the water is contaminated with chemicals or toxins which would not be affected by boiling and /or would cause medical problems from contact with the water.

3. Activate the telephone contact tree immediately. If contamination is in the ARWTP, one of the raw water sources feeding the plant and/or the Lee Well ground water, shut down the plant or well as appropriate. Locate the source of contamination and initiate remediation.

4. If the contamination is only in the distribution system, keep the plant and the well running and flush the system until the contamination is no longer detectable.

5. The need for a Do Not Use order will initiate Durham and UNH emergency management protocols including opening of emergency operating centers and immediate implementation of notification and update communications to the community, campus and State agencies. The Chief Operator or on‐ duty Operator will notify the Director of Energy & Utilities or his/her chain of command until a senior UNH official has been notified of the need for a Do Not Use order.

6. Once all respective authorities have been notified, follow the section on obtaining alternate water supplies.

7. The Do Not Use Order will only be rescinded after approval from NHDES.

SECTION 4B. CRITICAL USERS

List unique service customers including but not limited to schools, day cares, nursing homes and hospitals, and include a brief description of how you will notify them and provide for their water needs.

SECTION 6. SYSTEM COMPONENTS

SECTION 6A. SYSTEM EQUIPMENT & CHEMICALS

The following is an up‐to‐date list of the assets of the UNH/Durham Water System. The biggest change from the previous ERP was the replacement of the UNH Arthur Rollins Water Treatment Plant by the new UNH/Durham Water Treatment Plant and the addition of the Aquifer Recharge and Groundwater Facility at Spruce Hole.

UNH/Durham Water Treatment Plant

Raw Water and Impoundments

Primary Source The Lamprey River Capacity 1,389 GPM Total Drainage Area 184 square miles Elevation of dam 60 ft MSL Total Storage Approximately 90 million gallons

Drainage area is mixed rural residential and industry. State Route 125 runs parallel to the Lamprey River. Also there are fuel storage areas within the watershed.

Secondary Source The Oyster River Capacity 1,389 GPM Total Drainage Area 16.5 square miles Elevation of dam 47.0 ft MSL Top of Flashboards 49.16 ft MSL Total Storage Approximately 9 million gallons

Drainage area is primarily rural residential with secondary travel ways. There is one portion with State Route 4 and a major fuel storage area within the drainage area.

Additional Source Spruce Hole Well Capacity 725 GPM (1.04 MGD for up to 60 consecutive days 120 GPM (172,800 GPD year round)

Receives water from Lamprey River (up to 1.44 MGD) during high flow periods to be recharged into the Spruce Hole Aquifer for later withdrawal and use during periods of drought and peak demand

Intake Structures

Facility Lamprey River Pump Station River Intake 16‐inch diameter cement lined DI pipe Motor GE 75 HP Pump Crane Deming 6”x 6” Capacity 1400 GPM Effluent Discharges either directly into the UNH/Durham Water Treatment

Plant or the recharge the Spruce Hole Aquifer.

Facility Oyster River Gatehouse Upper Intake 10” CI, 40 ft MSL

Lower Intake 24” CI, 33 ft MSL Intake covering CI bar rack, and plastic screen Valves Manually operated Bypass Connected to intake manifold, manually operated Ice Control Air compressor

The UNH/Durham Water Treatment Plant has three separate raw water sources, namely the Lamprey River, the Oyster River and the Spruce Hole Well. The operator can select flow rates from each source based on water quality and the water withdrawal limitation at each location. For example water can be withdrawn from the Lamprey River only if river flows are above a pre‐determined minimum flow. Raw water is pumped from the three sources to the plant where it then enters the pretreatment process.

Pre‐Treatment (Chemical Addition, Rapid Mix and Flocculation)

Pretreatment includes the addition of potassium permanganate (KMnO4) and/or caustic soda (NaOH), to condition the water for clarification. A third chemical application is provided in the event a third chemical is required. A coagulant (PACL) is then added to the conditioned and blended water prior to it entering the three rapid mix basins.

After 5 to 14 seconds of rapid mix, the water then proceeds immediately to the flocculation basins. Approximately 15 minutes is allowed for the formation of floc.

Clarification

The coagulated water exits the three flocculation basins and enters a common channel, which transports it to the plate settler clarifiers. Each clarifier is designed to treat 670 GPM. The detention time is approximately 1.5 hours (at maximum flow) and 4.0 hours at the average flow rate of 260 GPM. Horizontal basin velocities 0.38 FPM and 0.15 FPM during max and average day flows, respectively.

Filtration

Clarified water exits the plate settlers and enters a common channel where it is transported to one of four deep bed dual media filters. The dual media consists of 36 inches of anthracite above 10 inches of sand. The filters provide a total 560 SF (140 SF per filter). Filtration rates vary between 1.2 and 3.1 GPM/SF.

Filters are backwashed with a combination of air and water. The filters are first scoured with air at a flow rate of 5 SCFM/SF for an operator determined period of time. This is followed by approximately 5 minutes of combined air scour (5 SCFM/SF) and low water wash (6 GPM/SF) This is followed by a water only backwash at a rate of 17 GPM/SF for approximately 5 minutes. The last stage of backwash takes about a minute at a flow rate of 60 seconds.

Disinfection

Filtered water then enters two chlorine contract tanks. Each tank is sized to handle the full plant design flow.

Typically only one tank will be operational at a time. The tanks are sized to achieve a 2‐log reduction of viruses and a

0.5 log reduction in Giardia. Giardia dictates the disinfection required. The tanks provide an effective concentration contact time (CT) of 42mg/L‐min at a water temperature of 5 deg F and a pH of 7.5 with a free chlorine residual of

1.0 mg/L.

Finished Water Pumping

Disinfected water flows to one of three interconnected clearwells providing a total of 55,000 gallons of storage.

(Clearwell 1 – 25,000 gal; Clearwell 2 – 15,000 gal; Clearwell 3 – 15,000 gal) The plant has three finished water pumps. Each is rated for 675 GPM at 206 Ft TDH. Finished water pumping is controlled to maintain a constant clearwell level, thereby maintain the required CT value of 42. The difference between actual water demand and finished water pumping is provided by distribution storage. Finished water is pumped into the Main Pressure Zone at an HGL of Elev. 207 set by the Foss Farm Tank.

Solids and Waste Stream Handling

The Solids and Waste Stream Handling process is designed to receive process flows from the following.

Settled Solids from the Plate settle clarifiers – Estimated volume 7,200 gallons

Spent backwash water from the filters ‐ Estimated volume 25,000 gallons

Filter to waste from the filters – Flows directly to the Recycle Wetwell located at the Oyster River Pumping Station

Tank drainage – Infrequent and piped directly to the dewatering lagoons

Plant overflows – Infrequent and piped directly to the dewatering lagoons

Three dewatering lagoons are provided to store, thicken, and dewater residuals contained in the clarifier sludge and the spent backwash water.

Chemical Feed Systems

Liquid chemical feed systems are provided for Polyaluminum Chloride (Coagulant), Sodium Hydroxide (pH adjustment), Sodium Hypochlorite (disinfection), and Phosphate (Corrosion Inhibitor). Each system includes a fill station, bulk storage tank, transfer pump, day tank and either a duplex or triplex metering with the necessary appurtenances for proper chemical feed.

A dry Potassium Permanganate chemical feed system also is provided. Dry permanganate is delivered in 55‐gallon drums. It is then mixed to form a 2% solution. A metering pump then delivers the solution from the solution/mixing tank to the injection point.

Other assets that are important to the operation of the UNH/Durham Water system are listed below.

Wiswall Dam

This dam is a concrete rubble dam constructed circa 1920 located approximately 200 feet downstream from Wiswall

Road. It impounds a portion of the Lamprey River which is the primary water supply for the UNH Durham water system. The dam was reconstructed following the 2006 Mother’s Day flooding. In addition to repairing the flood damage, the gates were rehabilitated, stop logs were added to provide flexibility in maintaining minimum flows during drought conditions, and a fish ladder installed. The dam is visited daily by either the Water Department personnel or NH Fish and Game. It is in clear view of the Wiswall Road Bridge. John Hatch Park and the Wiswall Falls

Mill Site abuts the dam.

Lamprey River Pump Station

The Lamprey River pump station is located approximately 2,600 LF upstream from the Wiswall Dam. The station consists of a single pump which pumps water to either the Spruce Hole Groundwater Recharge site or to the

UNH/Durham surface water treatment plant. It does not have an emergency generator. The station is located at the end of an approximately 1,400‐foot long gated and locked access road near the intersection of Packers Falls Road and Wednesday Hill Road. The station is visited on a daily basis by UNH/Durham personnel. A fence with a locked gate, surrounds the station and the entrance door also is locked. However, there are no surveillance cameras or operational intrusion alarms at this location.

Spruce Hole Groundwater Supply and Artificial Recharge Facility

This facility is composed of a 130‐foot deep gravel pack well, a control building and two recharge basins. Water from the Lamprey River is pumped to this facility during times of high river flow and is used to recharge the local aquifer.

The Lamprey River pump station was recharging the aquifer at the rate of 230 GPM during our visit. When surface water flows are down water is removed from the aquifer and pumped to the UNH/Durham WTP for treatment.

There is no emergency generator on site. The access road to this facility is gated and locked. There are no surveillance cameras or operational intrusion alarms.

Lee Well

The Lee Well is a gravel packed well with a casing diameter of 18 inches and a depth of 54 feet. It is equipped with a

7‐stage vertical turbine pump operating at 700 GPM @ 225 ft TDH and is driven by a 60 HP motor. The well accounts for about 25% of the water used by the customers of the UNH/Durham water system. Operation of the well is based off water level in the Beech Hill Tank (HGL = Elev. 305. Access to the well is via a locked and gated access road. UNH/Durham feeds four chemicals to the ground water at this location, namely 12.5% sodium hypochlorite;

sodium hydroxide; blended poly orthophosphate and fluoride. Back‐up power is provided by a direct drive propane driven engine. Bulk storage of sodium hypochlorite and sodium hydroxide are located in a separate room from the well pump, controls, and polyphosphate feed system. The station is visited daily. The doors are locked. There are no surveillance cameras of intrusion alarms active at the well.

Beech Hill Tank

The Beech Hill Tank is a nominal 0.6 MG, 32‐foot tall x 58 feet in diameter, welded steel tank constructed in 1985. It is located off Beech Hill Road in a fairly remote area. It provides water to the High Pressure Zone of Durham generally located in the northwest corner of Durham between US Route 4, NH 155A and the borders of Durham with

Madbury to the north and Lee to the west. The access road is gated and locked. A fence with a locked gate surrounds the tank itself.

UNH WTP and Oyster River Pump Station and Dam

The water treatment plant, pump station, and dam are collocated with UNH Grounds & Roads adjacent to the UNH

Police Department on Waterworks Road. The plant is staffed Monday thru Friday 8 hours per day. The plant treats surface water from the Oyster River Pump Station and the Lamprey River Pump Station. Finished water is pumped into the Main Pressure Zone at an HGL of Elev. 207 set by the Foss Farm Tank.

Foss Farm Tank

The Foss Farm Tank is a 3.0 MG, 110‐foot tall x 68 feet in diameter, welded steel tank constructed in 1976. The access road is gated and locked. In addition to providing storage to the Main Pressure zone it also is the site for communication facilities for both the Town of Durham and cell phone service providers.

Madbury Road Booster Station

The Madbury Road Booster Station is a below grade structure serving the residential area in the surrounding area.

The HGL of the Madbury Road Boosted Pressure Zone is Elev. 281.6. The station itself is located approximately ten feet behind the guard rail on Madbury Road near Littlehale Creek approximately 500 feet north of Edgewood Road.

The hatch is locked. There are no fences or intrusion alarms at this facility. The station consists of two ON/OFF booster pumps and two hydropneumatics storage tanks which operate between 71 and 85 psi.

Technology Drive PRV

The Technology Drive PRV is a below grade facility located about 25 feet off the edge of pavement on Technology

Drive approximately 100 feet north of its intersection with NH 155A. This facility allows water from the Beech Hill

Tank High Pressure Zone to be bled back into the Main Pressure Zone. A small booster pump allows water to be pumped from the Main Pressure Zone into the Beech Hill Tank High Pressure Zone.

Transmission/Distribution Approximately 29 miles of 2”‐12” water mains

A system as‐built plan exists and is located in the Facilities Plan Room at Ritzman Hall at 22 Colovos Road, Durham, NH. GIS plans are also available online for authorized UNH Durham Water System staff.

SECTION 6C. SYSTEM DEMAND

Include a brief description of this system’s ability to isolate sections of the distribution system and how this system could utilize demand reduction and excess capacity during an emergency.

What is the total production capacity of this system? Gallons per day = 2.10 Million

What is the total storage capacity of this system? Gallons = 3.6 Million

What is the average daily demand of this system? Gallons per day = 900,000

What is the maximum daily demand of this system? Gallons per day = 1.4 Million

Est’d Available Water (Storage/Avg day demand) Days = 4

SECTION 7. ALTERNATE WATER SOURCE

The UNH/Durham water system has four sources of water, spread out geographically throughout the Town and one source in the Town of Lee. Three of these sources (Lamprey River, Oyster River and Spruce Hole) feed into the UNH/Durham Water Treatment Plant. If an emergency makes one of these sources unavailable, the remaining two will continue to provide water to the Town. The Lee Well feeds the Beech Hill Tank, which is at a higher elevation than the Foss Farm Tank. Water could be bled from Beech Tank through the Technology Drive PRV. In the event the Lee Well is taken off‐line, UNH Durham would need to truck water from the Foss Farm pressure zone to Beech Hill.

The Town will be improving the Technology Drive PRV to have a functioning booster pump to effectuate this transfer.

SECTION 7A. BULK AND/OR BOTTLED WATER

Include descriptions of how you would receive bulk water or distribute bottled water to customers.

1. Should the water supply become contaminated for any reason which would make it non‐potable, an alternate water supply will have to be obtained. In order for this to happen, mandatory water restrictions would have to be implemented.

2. If bulk water is to be purchased, there is a list of vendors in the Emergency Vendor List in Section 3.D.

of this document.

3. If bulk water is to be provided by the NH Army National Guard, the Durham Town Administrator must declare an emergency. Once an emergency is declared, The Durham Town Administrator will contact the NH Office of Emergency Management. The NH Office of Emergency Management will then contact the NH Army National Guard. The NH Army National Guard can supply Reverse Osmosis Water Processing Units (ROWPU) and haul water from uncontaminated sources.

4. The NHDES guidelines suggest putting bulk water into the storage tanks if possible. The UNH/Durham Water System has 2 tanks. The Foss Farm tank (largest @ 3MG) has no fill ports. The Beech Hill tank is not easily accessed but there is a booster pump at the pressure reducing vault which if connected to a bulk delivery, could pump water to the tank. The tank is also of a manageable size and with its elevation could supply pressure to the entire system.

SECTION 7B. INTERCONNECTIONS WITH ADJACENT WATER SYSTEMS

The UNH/Durham Water System does not have any interconnection agreements with other water systems.

SECTION 7C. NEW SOURCE / REACTIVATION

The UNH/Durham Water System has four geographically disbursed sources of water, as described above .

SECTION 10. CYBERSECURITY

The University of New Hampshire and the Town of Durham have conducted reviews of their cybersecurity systems protecting both their Business Enterprise and Process Control Systems. They have put into place the following items to thwart potential threats, mitigate their vulnerability to cyberattack, and respond to actual threats in the event a cyber actor or nation‐state successfully makes it through the firewalls. The recently completed Risk and Resiliency

Assessment considered cyberattacks on the following components of the water system

Lamprey River Pump Station – This facility is owned by UNH and operated by UNH through its operation and maintenance contract with Woodard & Curran. The station is not connected to the internet and not subject to cyberattack. All pump and valve control is initiated on‐site.

Spruce Hole Groundwater Supply and Artificial Recharge Facility – This facility is owned by the Town of Durham and is jointly operated by UNH and Town of Durham through its operation and maintenance contract with Woodard & Curran. Pump and valve control can be performed both on‐site and remotely using SCADA.

Woodard & Curran monitors its cyber systems daily to identify potential breaches in security; has erected firewalls; uses encrypted software and password protections; as well as frequent software upgrades to thwart a cyberattack and mitigate their vulnerability.

Lee Well ‐ This facility is owned by the Town of Durham and is jointly operated by UNH and Town of Durham through its operation and maintenance contract with Woodard & Curran. Pump control can be performed both on‐site and remotely using SCADA. Process control, e.g. chemical feed rates, must be initiated on‐site.

Woodard & Curran monitors its cyber systems daily to identify potential breaches in security; has erected firewalls; uses encrypted software and password protections; as well as frequent software upgrades to thwart a cyberattack and mitigate their vulnerability.

UNH WTP and Oyster River Pump Station ‐ This facility owned by UNH and operated by UNH through its operation and maintenance contract with Woodard & Curran. Pump, valve, and process control can be performed both on‐site and remotely using SCADA. Woodard & Curran monitors its cyber systems daily to identify potential breaches in security; has erected firewalls; uses encrypted software and password protections; as well as frequent software upgrades to thwart a cyberattack and mitigate their vulnerability.

Madbury Road Booster Station – This facility is owned and operated by the Town of Durham. It is not connected to the internet. All control must be initiated on site.

Technology Drive PRV and Booster Pump Station ‐ This facility is owned and operated by the Town of Durham.

It is not connected to the internet. All control must be initiated on site.

As described above, all Process Control System connected to the internet are monitored by UNH’s operation and maintenance service provider, Woodard & Curran. They have developed a protocol to monitor their cyber based systems to identify potentially malevolent activity; take steps to limit damage from that malevolent activity

(including taking the entire system, or parts of it, off line); to initiate manual operation of the UNH WTP, the Oyster

River Pump Station; Spruce Hole Groundwater Recharge Facility and the Lee Well; to restore normal operations once the breach has been identified and corrected; to notify UNH and Durham utility personnel and local officials

(Sections 2 and 3), NHDES, and the Dept of Homeland Security, as well as critical users within the distribution system

(Section 4B) impacted by the breach .

This plan and protocol includes steps to document activities leading up to an during the incident as well as the steps taken by UNH Durham in response to the incident.

SECTION 11. RISK ASSESSMENT

The UNH/Durham Water Department performed a Risk and Resiliency Assessment (RRA) of the various components of its water supply, treatment, and distribution system. Table 11.1 Summarizes the conclusions and findings of the

RRA effort regarding Malevolent Acts. Table 11.2 summarizes the conclusions and findings for Natural Hazards.

Appendix A – Response to Specific Emergencies of the ERP contains detailed descriptions to guide the actions of

UNH/Durham Water Department staff during an emergency. The emergency response actions from the previous ERP are listed below.

A. Main Breaks B. Tank Failure C. Power Outages D. Plant Failure E. Lee Well Failure F. Large Chemical Spill G. Small Chemical Spill H. Raw (Source) Water Contamination I. Natural Disasters/Unpreventable Accidents

These responses have been reviewed and updated and are included as Appendix A to this Emergency Response Plan.

In addition to the above a tenth item has been listed, namely J. Cyberattack

A review of the event specific response presented in Appendix A and the findings of the Risk and Resiliency

Assessment indicates UNH/Durham already has addressed their response to each of the Malevolent Acts and Natural

Hazards listed on Tables 11.1 and 11.2. In addition to identifying the Malevolent Act or Natural Hazard that could impact a component of the water system, Tables 11.1 and 11.2 also describe the UNH/Durham response. For example if there is a physical assault of a storage tank, UNH/Durham would implement the steps described in

Response B ‐ Tank Failure and I ‐ Unpreventable Accidents

Natural Hazards

APPENDIX A.

RESPONSE TO SPECIFIC EMERGENCIES

A. MAIN BREAKS

In the event of a transmission main break.

1. If a UNH line breaks, contact Facilities Control Center. They will contact the UNH Utilities Crew to shut the main down. If a Town of Durham line breaks, contact town personnel listed in Section 3.D. of this document.

Contact the fire department to notify them.

2. If the plant is maintaining water quality, leave plant running until the main is ready to be shut down or water quality degrades below operating standards.

3. Contact the Water Treatment Plant Chief Operator and notify the Fire Department.

4. If the Chief Operator is not available, contact the UNH Director of Energy & Utilities and the Durham Town Engineer.

5. Once the necessary people have been contacted, coordinate efforts with repair personnel.

6. Once the extent of the break is known, get estimate on how long it may take to fix.

7. If down for at least a day, have the Lee Well run to maintain water supply.

8. If the break cannot be fixed for an extended period of time (2 days +), water system personnel will advise the joint UNH/Durham Water, Wastewater, Stormwater Committee who will issue the appropriate water conservation stage alert.

9. Keep watch on the pressure. If the plant has been isolated, you will have to check the pressure at the Foss Farm tank. 35 psi is the minimum pressure before action is required.

10. When the Foss Farm Tank has 35 psi notify the repair crew and if possible isolate one of the 2‐12” mains and start the plant. The main, which is not broken, will be used. The plant will have to run in manual mode.

11. When the break has been fixed, ensure the repair has been disinfected with either sodium hypochlorite solution or crushed chlorine tablets.

12. After disinfecting, flush the main to remove any air. Flushing should last until the water runs clear or 15 minutes, whichever is longer.

13. Start plant and return to normal operating procedures.

B. TANK FAILURE

1. In the event of a tank failure to either THE Foss Farm OR Beech Hill Tanks due to rupture, vandalism, sabotage, or natural disaster the tank will be isolated from the rest of the distribution system.

2. Contact Facilities Control Center and Town of Durham staff listed in Section 3.D. of this document to inform them of the situation and request assistance in isolating the tank.

3. Contact the UNH Director of Energy & Utilities, the Durham Town Engineer, and the NH DES Water Division (Rick Skarinka).

4. If it is one of the town tanks (Foss Farm, or Beech Hill) notify the Durham Town Engineer or the Durham DPW staff listed in Section 3.D. of this document by phone.

5. If required to reduce tank leak rate but maintain system pressure, lower the high lift pump rate.

6. Monitor the pressure and the treatment process until the system finds an equilibrium.

7. When the tank is ready to come back into service, super chlorinate and open the fill line ¼ of full open and fill the tank slowly.

8. When the tank is full, shut the fill line valve.

9. Take a bacteria and VOC sample.

10. When negative results are obtained, neutralize the chlorine to 4.0 mg/l or less.

11. Open the fill line completely and the tank is now in service.

C. POWER OUTAGES

1. During a campus power outage, the plant emergency generator will automatically start and provide power to continue plant operations.

2. When the change‐over occurs, check all process meters, treatment systems, and readings for accuracy and operational status.

3. Check on the Lee Well status.

4. Monitor system for unusual readings.

5. Check on fuel status for emergency generator. Order fuel when tank is half full.

6. Check emergency generator regularly while running; look for signs of over heating, loose parts, etc.

7. Should the entire area be without power, have the town personnel start the Lee Well emergency engine when it is needed.

8. The Beech Hill tank level will have to be monitored visually.

9. When power returns, follow steps 2‐4.

10. Return to normal operations.

D. WATER TREATMENT PLANT FAILURE

This will cover the most common reasons for plant failure at the Arthur Rollins Treatment Plant.

1. When the plant fails, the first thing to do is to determine what caused the failure. This could mean flows, water quality, or the emergency generator failed.

2. If a flow caused the plant to fail, determine if it was low or high flow by using the charts on the SCADA program. If it was low flow, check strainers, valves, level indicators, pressure, and motor/pump conditions. If it was high flow, check valves, pressure, level indicators. For both cases check to see if the SCADA system is functioning properly.

3. If the shutdown was caused by water quality, there are several possibilities to look for. The first thing is to look at what process has the water quality problem.

4. Once the process is determined, it will be necessary to examine all monitors for that process. This will tell you what to look for. For instance, if the turbidity is high in the mid‐basin, look at the turbidimeter to see if it’s reading properly and take a grab sample.

5. If the turbidimeter is correct, look at the rapid mixers and floc mixers to make sure they are functioning. If they are functioning then go to the weighing agent pump to ensure it is working properly, if it is working, check the PCH 180 pump. If all of these units are working properly then you will have to do a jar test to verify proper dosage.

6. Should whatever is found to be wrong is not readily fixed you will have to start the contact list. The first person to contact is the Chief Operator.

7. This person will coordinate with other people on the contact list and make arrangements for repair.

8. Should the Chief Operator not be available contact the next person on the list. This is the Director of Energy & Utilities. Proceed with the contact list should each contact be unavailable.

9. Once the contact list has been notified of the situation, the person on charge will contact necessary personnel from the Emergency Repair Contact List.

10. Once repair people have been contacted and have surmised the situation, get an estimate on how long before it can be fixed.

11. If repair time is to exceed two days before the plant can go on line, an alternate source of water will have to be activated. The media will also have to be notified. This will be initiated by the UNH Director of Energy & Utilities or higher.

12. Once repairs are completed the plant will have to be restarted. Make sure equipment, valves, and other items are in operational status.

13. Start the plant, running at a reduced flowrate. As the plant settles back to normal operation, slowly increase flowrate to normal, then have the alternate source shut off.

14. Keep campus and Town officials up to date on plant status.

E. LEE WELL FAILURE

Should the Lee Well fail or have to be shut off because of proprietary chemical problems, shut the well pump off, then notify the Chief Operator at the ARWTP. The Chief Operator will notify the Durham Water System Operator of the situation. Should the Town Durham Water System Operator not be available contact the Director of Public Works and/or the Town Engineer. The Town will then take necessary actions to correct the problem.

F. CHEMICAL SPILL, LARGE

1. Do not panic. If contaminated, remove clothing and shower.

2. Call 911 hours. Notify dispatcher of location of spill and substance if known.

3. Notify personnel in the area.

4. Don Personal Protective Equipment (PPE).

5. Assist first responders in containing the spill as requested.

6. If fumes are flammable, turn plant off and shut off breakers at Motor Control Center.

7. Remain on site until Hazmat team arrives and all information is relayed.

8. Contact Environmental Health and Safety (CAMPUS ONLY)

9. Contact Chief Operator/Town Water System Operator

10. The Chief Operator/Durham Water System Operator will make the necessary arrangements to resume normal operation as soon as possible.

11. There are empty storage tanks in the chemical storage area. One is a 150 gal/day tank and two 2250 gallon bulk tanks. These tanks can be utilized for temporary chemical storage if we have a spill in the plant.

12. The chemical, which is spilled, will be transferred, if possible, to the appropriate spare tank.
