2. EMERGENCY ACTION PLAN OVERVIEW Three emergency stages, ranked by severity, will be established for the Lower Ash Pond. Emergency Stage Definitions Stage 1: Non-Emergency failure is unlikely, and storm development or operational malfunction is slow in advancing to a potential emergency. This stage indicates a situation is developing such that the dam is not in danger of failing, but if it continues failure may be possible. Stage 2: Potential Failure storm development or operational malfunction that could result in failure of the dam is quickly accelerating. This stage indicates that a situation is developing that could result in a dam failure. Stage 3: Imminent Failure storm development or operational malfunction has reached a point that the failure of the dam has started or is imminent. This stage indicates dam failure is expected or occurring and may result in flooding that will threaten life and/or property downstream of the dam. Stage 2 conditions include Stage 1 conditions and responsibilities, and Stage 3 conditions include both Stage 1 and Stage 2 conditions and responsibilities. The Dam Owner, Dam Operator, or Designee may use the following Table to assess weather conditions and operational conditions at the dam to determine the appropriate actions for notifying emergency personnel during potential and actual emergencies. The closest rain gauge to the Lower Ash Pond Dam is located at the Richmond International Airport and operated by the National Weather Service. Therefore, rain gauge monitoring references to obtaining rainfall data from the airport. 2017.04.14 LAP EAP 2 April 2017

4. STATEMENT OF PURPOSE The Lower Ash Pond is designed and operated pursuant to Virginia Department of Conservation and Recreation Dam Safety and US Environmental Protection Agency Disposal of Coal Combustion Residuals from Electric Utilities regulations and generally accepted engineering practices. The purpose of this Emergency Action Plan (EAP) is to provide critical information and a plan of action in the event of an emergency situation at the Lower Ash Pond. The plan addresses the following: Delineation of inundation areas downstream of the dam; Procedures for determining when to initiate various emergency response levels; Provisions for notification of emergency responders and owners of potentially affected downstream residences and structures; Emergency preparedness and exercises; and Documentation of evacuation routes. This plan is intended to meet the requirements of 4 VAC 50-20-175 of the Virginia Department of Conservation and Recreation Dam Safety regulations and 40 CFR 257.73(a)(3) of the Federal Disposal of Coal Combustion Residuals From Electric Utilities Final Rule (CCR rule). Pursuant to 40 CFR 257.73(a)(2) of the CCR rule, a hazard potential classification assessment was performed for this surface impoundment in October 2016. The assessment of the Lower Ash Pond resulted in a hazard potential classification of significant hazard under the CCR rule. 5. PROJECT DESCRIPTION a. General Vicinity The Lower Ash Pond is located just south of Coxendale Road about half a mile southeast of Chesterfield Power Station in Chesterfield County, Virginia. A site vicinity map is included in Figure 1. To the west, the Lower Ash Pond is bounded by a water feature commonly known as the Thermal Channel, which is the receiving body of water for non-contact cooling water effluent associated with operation of the Chesterfield Power Station. To the south, the pond is bounded by the old channel (oxbow) of the James River and open space. To the east, the pond is bounded by Henricus Park Road and the Dutch Gap Conservation Area, which is comprised of wetland and forested areas. b. General Description of Dam The Lower Ash Pond was formed in 1964 by constructing an earthen embankment dam on its east, south and west sides to form a pond with a normal pool surface area of approximately 30 acres. The maximum height of the ash pond perimeter embankment is about 20 feet. The east, west and south embankments have crest elevations ranging between El 18.5 and El 22.0. In accordance with s VPDES permit, surface water from the top of the pond is discharged from the Lower Ash Pond into Farrar Gut, an oxbow of the James River, through the pond s principal spillway / decant structure, which is located near the southwest corner of the pond. The principal spillway system consists of a pipe and riser with a crest elevation of 15.8 feet. The pipe is a 27-inch diameter reinforced concrete pipe with a length of about 90 feet. The pipe has an upstream invert at El 9.4 and a downstream invert at El 6.8. The riser is a two-stage concrete structure. The first stage consists of an opening on the upstream face of the riser with an invert at El 15.8. The opening has dimensions of 6.25 feet long by 0.8 feet high. The weir at this opening can be adjusted between El 15.8 and El 17.2 to control the water level in the pond. The second stage is a square 2017.04.14 LAP EAP 7 April 2017

opening on top of the riser at El 17.5. This opening, which has dimensions of 5.9 feet by 5.4 feet, is covered with a grate. There is also an emergency spillway to the north of the riser structure. The emergency spillway is located on the access road at the top of the embankment and has a bottom width of approximately 100 feet with an invert of El. 18.0. 2017.04.14 LAP EAP 8 April 2017

6. EMERGENCY DETECTION, EVALUATION, AND CLASSIFICATION The dam owner and/or operator is responsible for operation and maintenance of this dam. The dam operator and the field observer are responsible for monitoring conditions at the dam, spillway, and staff gauge and notifying the Local Government Emergency Services Coordinators when emergency stage conditions are activated. The dam owner/operator may initiate this EAP based on the issuance of a flood watch or warning in the area, or if conditions at the dam indicate that water levels in the impoundment will rise to the point where there is flow through the emergency spillway. Embankment erosion, appurtenant malfunction, or any of the other conditions described in this section may also dictate initiation of the emergency action. While it is the dam owner s responsibility to initiate this process, the Local Government EOC may contact the dam owner to inform the team that a flood watch has been issued locally by the NWS and team members would initiate their duties as required in this EAP. Depth of flow through the emergency spillway is the best indication of flood conditions and should be used as an indicator of the potential impacts downstream. In the absence of actual flow depth data through the emergency spillway, measured rainfall depths in inches monitored in the contributing watershed may be used to determine the emergency level. Visual observations should be made by a team member so that accurate and up to date information can be provided to the EOC. a. Flow Depth in Emergency Spillway Reservoir pool level, associated with the flow depth in the emergency spillway, is the prime indicator of flooding conditions at Dominion Generation Lower Ash Pond. Initiate a Stage 1 Condition when the reservoir pool level is at elevation 17 feet (pool elevation can be read electronically from the level sensor or visually from the staff gauge located at the riser). This is one foot below the level of the emergency spillway and would provide for increased monitoring as pool levels begin approaching the emergency spillway elevation. Initiate a Stage 2 Condition when the reservoir pool level is at elevation 18 feet (pool elevation can be read electronically from the level sensor or visually from the staff gauge located at the riser). This is the crest elevation of the emergency spillway and the spillway flow depth would therefore be zero feet, but the spillway would be on the verge of discharging. Initiate a Stage 3 Condition when the reservoir pool level is at elevation 18.5 feet, or the flow depth in the emergency spillway is 0.5 feet (pool elevation can be read electronically from the level sensor or visually from the staff gauge located at the riser). This would occur when the pool level would be one-half-feet below the dam crest and would indicate that overtopping of the dam embankment could soon occur. 2017.04.14 LAP EAP 9 April 2017

b. Rainfall Depths Rainfall depth for various storm durations are another indicator of potential flooding conditions. Initiate a Stage 1 Condition upon issuance of NWS flood warnings or for a continuous rainfall longer than 24 hours of any depth at the closest NWS gage (Richmond International Airport). Initiate a Stage 2 Condition for the following rainfall depths (100-year event): 5.6 inches in six hours 7.0 inches in 12 hours 8.4 inches in 24 hours Initiate a Stage 3 Condition for the following rainfall depths (1,000-yr event): 8.2 inches in six hours 10.7 inches in 12 hours 13.1 inches in 24 hours c. Observation Frequency Dam, spillway, and staff gauge observations shall occur at frequencies determined by the Emergency Stage condition: Stage 1 conditions observations shall occur at six-hour intervals Stage 2 conditions observations shall occur at two-hour intervals Stage 3 conditions continuous observation Observers should use safety and be aware of the potential for flooded roads along the route to the dam. Monitoring and surveillance of conditions at the dam will continue under emergency conditions as long as safety is not in question. d. Public Roads Downstream of the Dam There are no public roads downstream of the dam that would be impacted as a result of a dam failure. 2017.04.14 LAP EAP 10 April 2017

e. Additional Emergency Conditions The following table is to be used to initiate emergency conditions during events other than those related to precipitation and reservoir pool levels. If any of these conditions are observed, Dominion s Power Generation Engineering group should be contacted for further discussion, observation, and/or technical direction. Event Situation Emergency Stage Emergency Spillway and Channel Seepage, including observation of a break in the liner Sinkholes Embankment Cracking Visual movement of the spillway channel with no flow 1 Spillway is flowing and erosion/head cutting is observed 3 New seepage areas on or near the dam 1 New seepage areas with cloudy discharge or increasing flow rate Observation of new sinkhole on embankment 1 Rapidly enlarging sinkhole 3 New cracks in embankment greater than ¼ inch wide without seepage Cracks in embankment with seepage 1 3 1 Cracks in embankment with rapidly increasing seepage 3 Embankment Movement Visual movement of the embankment slope 1 Sudden or rapidly progressing slides of the slopes 3 Vortex in pond Whirlpool with discharge downstream 3 Measureable earthquake felt or reported on or within 50 miles of the dam 1 Earthquake Earthquake resulting in visible damage to the dam 1 Security Threat, Sabotage, and Vandalism Earthquake resulting in potential uncontrolled release of water from the dam Verified bomb threat that, if carried out, could result in damage to the dam Detonated bomb that has resulted in damages to the dam or its appurtenances Damage to the dam or appurtenances with no impacts to the functioning of the dam Damage to the dam or appurtenances that has resulted in seepage flow Damage to the dam or appurtenances that has resulted in potential uncontrolled water release 3 1 1 1 1 3 2017.04.14 LAP EAP 11 April 2017

f. Relaxation of Emergency Conditions Emergency conditions can be rescinded when the following events occur: The NWS ends a flash flood warning. After heavy rains have ended, the water level in the impoundment is below elevation 17 feet (the emergency spillway crest), and the water level is receding. In the event of an earthquake, overtopping of the dam, evacuation of inundation areas, or other serious problems resulting in a triggering of emergency conditions, the dam must be inspected by a knowledgeable professional engineer of the dam site. Termination of emergency conditions occurs when all entities notified of the emergency condition have been communicated with and informed of current non-emergency conditions. 2017.04.14 LAP EAP 12 April 2017

7. RESPONSIBILITIES UNDER THE EAP This section is intended to clearly outline the responsibilities of parties involved in all EAP procedures, including notification, surveillance, classification, evacuation, and termination. a. Dam Owner/Operator Responsibilities 1. The dam owner/operator IS RESPONSIBLE for notifying the local EOC of any problem or potential problem at the dam site. 2. The dam owner/operator/eap Coordinator WILL DETERMINE when Stage 1 conditions are met at the dam and WILL INITIATE dam surveillance accordingly. 3. The dam owner/operator/eap Coordinator WILL DETERMINE when Stage 2 conditions are met at the dam. 4. The dam owner/operator/eap Coordinator WILL DETERMINE when Stage 3 conditions are met at the dam. 5. The dam owner/operator/eap Coordinator WILL MAKE THE DECISION that an emergency condition no longer exists at the dam. 6. The dam owner/operator WILL BE RESPONSIBLE for operating pumps as needed for the dam to function effectively. b. Responsibility for Notification 1. The dam owner/operator/eap Coordinator WILL NOTIFY the 24-hour dispatch center and Chesterfield County EOC before beginning dam surveillance under Stage 1 conditions. 2. The dam owner/operator/eap Coordinator WILL NOTIFY the 24-hour dispatch center and the Chesterfield County EOC when Stage 2 conditions are met, in order to alert them to perform actions required for Stage 2 conditions and to review actions that may be required for the safety and protection of people and property and to mobilize their evacuation team. The dam owner/operator WILL NOTIFY the Regional Dam Safety Engineer and Dominion Power Generation Engineering that Stage 2 conditions have been implemented. 3. The dam owner/operator/eap Coordinator WILL NOTIFY the 24-hour dispatch center and the Chesterfield County EOC to initiate warning/evacuation of residents when Stage 3 conditions or imminent dam failure are probable. The dam owner/operator WILL NOTIFY the Regional Dam Safety Engineer and Dominion Power Generation Engineering that Stage 3 conditions have been implemented. c. Responsibility for Evacuation 1. The Chesterfield County EOC WILL NOTIFY the people, business owners, and land owners in the inundation zone (attached to the Dam Break Inundation Maps) of the potential emergency or evacuation prior to or in the event Stage 3 conditions are met. There will be no evacuations associated with the implementation of this Emergency Action Plan. There are no occupied structures or publicly travelled roads within the inundation zone 2017.04.14 LAP EAP 13 April 2017

2. The Chesterfield County EOC and 24-hour dispatch center should utilize their Standard Emergency Procedures (SEPs) to implement in the event that dam failure is possible or occurring. These SEPs should include evacuation plans. d. Responsibility for Termination and Follow-Up 1. Once the Stage 3 condition has been met, the dam owner/operator/eap Coordinator will continue to provide the Chesterfield County EOC with information concerning water level rise, erosion in the emergency spillway, and/or dam overtopping, as provided by the dam/spillway/staff gauge observer. It is particularly important for the Chesterfield County EOC to know when a breach is occurring to evacuate their rescue personnel. The staff gauge observer will remain at the dam until released from duty by the EOC. 2. Regional flooding may occur prior to an incident at this dam and could continue for long periods of time. The staff gauge observer needs to have plans for staying or returning to the dam as conditions worsen. The termination responsibility should be handled by the EOC. 3. Post flood event discussions should be used to determine strengths and weaknesses in the EAP while the experience is fresh in the minds of those living through it. e. EAP Coordinator Responsibility The EAP coordinator will be responsible for EAP-related activities, including (but not limited to) preparing revisions to the EAP, establishing training seminars, and coordinating annual face-to-face EAP exercises between representatives of the owner/operator and local emergency responders. This person will be the EAP contact if any involved parties have questions about the plan. f. Methods for Notification and Warning The following notification and warning method(s) are to be used during an emergency: Telephone/Reverse 911 automated warning systems Police/fire/sheriff radio dispatch vehicles with loudspeakers, bullhorns, etc. Personal runners from door-to-door alerting residents (as required) Radio/television broadcasts for area involved (as required) g. Evacuation Procedures There will be no evacuations associated with the implementation of this Emergency Action Plan. There are no occupied structures or publicly travelled roads within the inundation zone. 2017.04.14 LAP EAP 14 April 2017

8. PREPAREDNESS a. Surveillance This dam is unattended under normal operating conditions. The Dam Owner/Operator or EAP Coordinator should monitor the status of weather fronts through the NWS. The NWS maintains a hurricane center that reports on hurricanes, tropical storms & tropical depressions as they travel and affect coastal and inland areas. The web site address is: http://www.nhc.noaa.gov/ The station is staffed 24 hours per day by the Operations Department. An operator would be dispatched from the on-shift crew to observe the staff gauge during an emergency situation. The staff gauge observer should never put themselves in harm s way. In the event a hurricane or tropical depression occurs with high winds, the staff gauge observer shall use extreme caution while monitoring conditions. Preplanned access routes should be utilized, given that small streams crossing under state and local roads may flood, preventing safe access. The gauge observers and staff should never attempt to cross a road that has flood water crossing it at a depth greater than one-foot unless the vehicle is specially designed for that purpose. Alternative routes should be chosen for access by foot in the event that a car is unsafe for use. Other alternative means of transportation may be considered. b. Routine Inspections The Lower Ash Pond is inspected weekly by members of the station Environmental/Chemistry team in accordance with applicable Coal Combustion Residuals regulations. It is inspected monthly in accordance with the Virginia Dam Owner s Handbook. If any findings trigger an action level, the EAP will be put into place immediately. Any findings in question will be discussed with a Dominion Power Generation Engineer and a resolution determined by the next monthly inspection. Any maintenance needs will be relayed to the grounds contractor or landfill contractor within one calendar week. c. Alternative Systems of Communication Communications during a major rainfall event may be problematic. Telephone land lines may be used as the first means of communication. Cellular telephones can be used to supplement the land lines. Unfortunately, telephone lines, like electrical lines, are subject to damage by falling trees so radio communication during these events is normally required. d. Emergency Supplies Stockpiling of Materials and Equipment: The location of necessary supplies and materials, such as barricades, sand, sandbags, etc. are either stored onsite or readily available through our emergency response contractors. Emergency access to supplies and equipment should be planned before any emergency is called. Appendix C lists sources and locations of supplies and equipment that may be required during an emergency along with addresses and telephone numbers of the sources/suppliers. 2017.04.14 LAP EAP 15 April 2017
