2 Section 1: Introduction Platte-Clay Electric Cooperative, Inc. (PCEC) is a member-owned electric cooperative serving customers in a six-county area north of metropolitan Kansas City. Platte-Clay is a member of Touchstone Energy, a national alliance of local, member-owned electric cooperatives. PCEC began operating in 1938 and is one of the fastest growing cooperatives in Missouri. The cooperative has approximately 2,900 miles of distribution line and serves 23,000 customers in Buchanan, Caldwell, Clay, Clinton, DeKalb, Platte and Ray counties. The cooperative is governed by a nine-member board of directors. Platte-Clay Electric Cooperative s mission is to provide quality electric service beyond members and customers expectations while maintaining a sound financial structure providing the most competitive rates possible. Affiliated businesses of the cooperative are Propane Pardners, a propane fuel business; Platte-Clay Fuels LLC, which operates fuel stations in Platte City and Kearney; and Platte-Clay Properties, which provides sewer service. This mitigation plan will include only the electric cooperative functions of the business. Figure 1 depicts the geographic boundaries of the cooperative in relation to USGS local quadrangles within the state of Missouri.

3 PCEC serves a growing region north of the Kansas City metropolitan area. The office is located in Kearney, Mo. The cooperative employs about 70 workers and serves approximately 23,000 members. Residential customers account for 94% of memberships (21,620 members), while business customers make up the remaining 6% (1,380 members) of the membership. Table 1 provides the summary of metered customers by county.

4 Critical Facilities It is important in mitigation planning for the electric cooperatives to identify the critical facilities in each area and to be able to prioritize reconnection and back-up power needs. Platte-Clay provides electric service to five (5) school buildings, three (3) fire stations, and numerous emergency warning sirens. Future Development Platte-Clay Electric Cooperative has not reported any future development for this assessment update. Table 2 below illustrates the population trend for the counties served by PCEC.

5 Section 2: Asset Inventory PCEC has a variety of assets by type. Real estate owned by the company includes office buildings, garages and outbuildings throughout the service territory. As a distribution cooperative, PCEC does not own any electric generation or transmission infrastructure, but does own and maintain approximately 2,000 miles of distribution lines. Table 3 provides information on total asset valuation.

8 Section 3: Risk Assessment Risk Assessment Methodology: The risk assessment methodology used in the following section was utilized for both the statewide aggregation as well as for each individual cooperative chapter. Section 4 of the Statewide Summary details this methodology. Some variation in the availability of data exists between the electric cooperatives as each utilizes a different system of recording the impact of natural disasters. Any differentiation from the process below is explained in the individual cooperative s chapter as necessary. For the purpose of the risk assessment, the identified hazards for the Platte-Clay Electric Cooperative service area have been divided into two categories: historical and non-historical hazards. Based on the data collected for the update, the hazards have been reclassified to reflect the actual data available and those hazards with no data available have been reclassified as non-historical. This does not mean that a non-historical hazard will never cause damage; it just means there have been no impacts prior to this report. The potential still exists, but the probability of the occurrence is numerically zero. For the analysis in this plan non-historical hazard probability is stated as less than one. Historical Hazards are those hazards with a measurable previous impact upon the service area. Damage costs per event and a chronology of occurrences are available. The associated vulnerability assessments utilize the number of years of data and cost of each event to establish an average annual cost per year. For PCEC, hazards with historical data include tornadoes, severe thunderstorms/high wind/hail, flood and levee failure, and severe winter weather. Non-historical Hazards are hazards with no previous record of impact upon the local service area. As such, the associated vulnerability assessments for each of these hazards will have an occurrence probability of less than 1% in any given year, but the extent of damage will vary considerably. For PCEC, hazards without historical data include earthquakes and dam failure and wildfire. Each hazard has a unique impact upon the service area, requiring each hazard to utilize a different valuation amount depending upon the level of impact. Non-historical hazards assume damage to all general assets. For Historical Hazards, assets were divided into two groups based upon historical impact which were utilized in the hazard damage analysis: Overhead infrastructure assets and buildings o Used for Tornado damage assessments Valued at $326,513,326 Overhead infrastructure assets only o Used for: Severe Thunderstorm/High Wind/Hail Flood Severe Winter Weather Valued at $305,988,326 PCEC Page 8

9 Outage Information Platte-Clay Electric has kept thorough information for outages from 2006 to This information will be used as the basis for forming the risk assessment as it is the most complete information available to measure outage causes and expected outages for future events. In cases where exact outage information is not available, estimates will be used to supplement existing data. Platte-Clay logs the cause of each outage. The categories are suited to the cooperatives needs, but do not necessarily align to the hazard categories as outlined in this hazard mitigation plan. For instance, trees are a leading cause of unplanned outages; however, the cooperative does not record if the tree fell as the result of a thunderstorm, tornado or ice storm because the tree is the direct cause of the outage. Table 5 shows all causes of outages in Table 5 Causes of Outages for Platte-Clay in 2016 Cause Number of Outages Maintenance Routine 1,006 Lightning 230 Unknown 157 Tree in Right-of-Way 107 Animal 112 Public 91 Overhead Primary Assembly 79 Secondary 168 Transformer 54 Underground Primary Cable 35 Wind 15 Jumper 18 Power Supply 2 Maintenance Unplanned 25 Members Side 11 Other 2 Line Down 63 Pole 32 Reclosure 6 Tree Out of Right-of-Way 1 Underground Primary Assembly 6 Total 2,220 Source: PCEC Internal Records Platte-Clay experienced five major storm events in 2016, with the system average interruption duration index (SAIDI), the measure of average outage duration for each customer served, of minutes for all events and minutes for major storm events. PCEC Page 9

10 A. Historical Hazards Tornadoes Previous Occurrences Throughout Platte-Clay Electric s service territory, from , there have been 59 tornadoes. Since 2000, there have been 25 tornadoes in the service area. Figure 3 provides a pictorial representation of recorded tornado touchdown sites and paths since (Data for map collected from NOAA.) The most damaging tornado in recent times was a continuation of the tornado that moved out of Clay County after impacting Smithville and Smithville Lake on the night of March 6. [The tornado] reached its strongest rating and its widest size as it crossed out of Clay County into Clinton County while it crossed Smithville Lake. Like in Clay County several residences were impacted in Clinton County by this large tornado that reached 1000 yards wide at its largest point. The worst of the damage occurred just east of Smithville lake where numerous structures were completely destroyed, but like on the west side of the lake the worst of the damage seemed to occur where garage doors became a point of entry for 100+ mph winds and lifted the entire structure off of its foundation. The tornado continued across the rural portions of Clinton County, remaining at least EF-2 until it approached Lathrop, where it became smaller and didn't create as much damage. (NOAA Storm Events Database) Figure 3 Tornadoes in the Platte-Clay Service Area PCEC Page 10

11 Probability of Future Occurrence and Vulnerability From 2000 through June of 2017, PCEC s service area in Missouri experienced 25 tornadic events. Using the methodology described in Section 4, the probability of a tornadic event in Platte-Clay Electric s service area is 100% (25 events / 17.5 years) with an annual average of 1.4 events. According to cooperative records, two of the 25 events resulted in damage to cooperative assets, resulting in an 8% probability that any given tornadic occurrence will produce damage. The probability of a damaging storm in any given year is 11.4%. Table 6 contains information about damages and outages due to tornadoes in the PCEC service area. Table 6 PCEC Tornadic Event Summary Event Date Damage Estimates Outages Customers Reported Affected May 17, 2015 $90, March 7, 2017 $550, ,115 Total $640, ,101 Data provided based on internal PCEC records which reflect cost from the referenced event year. The total damage from tornadoes was $640,100; therefore the average annual damage cost is $36,577 for the 17.5 years since This averaged amount accounts for less than 1 % of PCEC s total overhead assets and building valuation. ($326,513,326) A total of 5,101 customers reported outages during recorded tornadoes since This would be an average annual 920 customers losing power due to tornadoes. When compared with the total number of customers served (23,000), it can be projected that 4% of all customers may report outages each year due to a tornadic event. Problem Statement Since the force of tornadic winds makes it very difficult to defend overhead assets, PCEC should continue to place lines underground whenever it is feasible. Severe Thunderstorms, High Winds and Hail Previous Occurrences From 1997 to 2016, the counties of Clay, Clinton, Platte, and Ray of Platte-Clay s service area experienced a total of 127 days with hail events and 136 days with thunderstorm/high wind events. Ninety-two percent of PCEC s assets are located in these four counties. In order to avoid over counting of events, the number of days with events was used since many events occurred in multiple locations on the same day throughout the service area. The most costly event to date occurred on May 2, 2008, when a bow-echo line of storms moved in from Kansas. Hurricane force winds of over 80 miles per hour were recorded in Clay County and surrounding areas. Numerous power lines were downed and other damage was incurred by PCEC. PCEC Page 11

12 Probability of Future Occurrence and Vulnerability The probability of a day with a hail event in the Platte-Clay service area in any given year is 100 percent (127 days / 20 years) with an average of 6.4 days of hail events each year. There were no hail events that are recorded as causing damage, resulting in a less than 1% probability that any given hail event will produce damage. The annual average number of days with a thunderstorm event is 6.8 over the twenty-year span of data. Table 7 provides a summary of those thunderstorm/high winds events which caused damage to cooperative infrastructure by date and cost estimate of damage. Four out of 136 occurrences caused damage to cooperative assets, resulting in a 2.9% probability that any given thunderstorm/high wind event will produce damage to PCEC s overhead assets and a 20% probability of a damaging storm each year. Table 7 PCEC Thunderstorm Event Damage Summary Event Date Total Damages May 2, 2008 $165,000 April 2, 2010 $33,200 August 20, 2010 $26,400 August 9, 2012 $9,800 Total $234,400 Source: PCEC Internal Records Based upon historical records, the total damage due to thunderstorm/high wind event for the PCEC is $234,400. The average annual damage cost of $11,720 ($234,400 / 20 years). This averaged amount accounts for less than 1% of PCEC s total overhead asset valuation ($305,988,326). Outage predictions are difficult to make due to limited data provided by the cooperative. High winds caused 15 outages in 2016 which is less than 1% of the outages recorded for the year. In 2016, lightning caused 230 outages, which is over 10% of the year s outages. Combined, high winds and lightning caused 245 or 11% of all outages. This would be about 1% (245 outages / 23,000 members) of the membership experiencing an outage due to thunderstorms during Problem Statement Even though the trend over the last several years has been towards the occurrence of more intense thunderstorms statewide, the damages to PCEC s infrastructure due to these events has been declining. Continuation of programs that have been successful in securing assets from this hazard is recommended. Flood and Levee Failure Flooding is a natural hazard that presents a recurring threat to Platte-Clay s infrastructure. Although limited to locations near rivers, flooding presents a danger when power lines cross rivers. Workers are not able to access poles or lines that are damaged or need servicing. Workers are also in danger by working in the floodwater. PCEC Page 12

13 Previous Occurrences The largest river in the Platte-Clay service area is the Missouri River, which borders Buchanan, Platte, Clay, and Ray counties. The cooperative s service territory touches the Missouri River in portions of each of these four counties, which have federal and non-federal levees. During the recent Missouri River flooding in 2011, Platte-Clay had approximately 15 miles of line which were taken out of service in Platte County. The areas of primary concern are in extreme southwest Buchanan County, western Platte County, and southeast Ray County. Figure 4 depicts the 100-year floodplain in relation to the cooperative s boundaries. (Map Source: FEMA HAZUS-MH, Q3, DFIRM from the FEMA Map Service Center.) Currently, inundation data for levee failure is not available due to issues surrounding mapping, appropriate models, and its close association with flooding events. Figure 4 PCEC Floodplain Locations Figure 5 provides the location of known state and federal levees within the cooperative s boundaries. (Map Source: U.S. Department of Agriculture, U.S. Army Corps of Engineers, Missouri Spatial Data Information Service.) PCEC Page 13

14 Figure 5 PCEC Levee Locations From 1997 to 2016, Platte-Clay s service area in Clay, Clinton, Platte, and Ray County experienced 117 separate flood events. Probability of Future Occurrence and Vulnerability Using the methodology described in Section 4, the probability of a flood in Platte-Clay s service area is 100 % (117 events / 20 years) with an annual average of 5.9 days of flood events in the four-county area. Only one event was recorded as causing damage, resulting in a less than 1% probability that any given flood occurrence will produce damage and a 5% chance of a damaging flood each year. This damage estimate included damage from the tornado event from May 17, The records available indicate damages caused by flooding at Platte-Clay are $90,210. The average annual damage is $4,511. This figure is less than 1% of PCEC s overhead assets ($305,988,326). The outages reported associated with flooding coincided with the May 17, 2015 tornado event. During this event 986 customers reported outages. The average annual number of customers experiencing an outage due to flood is about 49. This calculates to less than 1% of PCEC s 23,000 customers. PCEC Page 14

15 Problem Statement: The potential for losses to infrastructure and outages for customers is a possibility for Platte-Clay Electric during flooding events. Limited data on damages and outages makes a statistical analysis of the situation less meaningful at this time. Another concern for PCEC is the existence of large capacity dams upriver on the Missouri River. Severe Winter Weather Previous Occurrences From 1997 to 2016, the counties of Clay, Clinton, Platte, and Ray of Platte-Clay s service area experienced a total of 46 severe winter weather event days. These include significant snowfall events, ice storms and blizzards. The most significant event for PCEC was the ice storm that occurred in December of 2017 with most of the area receiving a half-inch coating of ice. Probability of Future Occurrence and Vulnerability The probability for severe winter weather in the cooperative s region is 100 % (46 events / 20 years) with an annual average of 2.3 days of severe winter weather. 1 of the 46 occurrences caused damage to cooperative assets, resulting in a 2.2% probability that any given severe winter weather occurrence will produce damage and a 5% chance of damaging winter weather each year. Table 8 provides a summary of the event date and associated damage estimates. Table 8 PCED Severe Winter Weather Event Damage Summary Event Date Total Damages December 10-12, 2007 $450,000 Source: PCEC Internal Records Based on historical records, the average severe winter weather event to affect the cooperative will cause an average damage cost of $9,783 ($450,000 / 46 events). The average annual amount of $22,500 accounts for less than 1% of Platte-Clay s total overhead asset valuation ($305,988,326). No outage predictions are possible due to insufficient data. There were no severe winter events recorded in the PCEC service area during 2016, which is the only year that data on outages was provided. Problem Statement Although economically difficult to accomplish, the placement of transmission lines underground provides safety from ice storms and high wind events. PCEC Page 15

16 B. Non-historical Hazards Wildfire The region served by Platte-Clay includes rural and developed areas. It does not contain any large forests, although there are areas of heavy trees. Rural areas are a combination of pasture and grasslands and row crops. For this analysis, the four counties of Clay, Clinton, Platte, and Ray will be used as less than 8% of the cooperative s overhead assets are located in Buchanan, Caldwell, and DeKalb County. Previous Occurrences Information for the period from 2004 to 2012 is available from the Missouri Department of Conservation through the 2013 Missouri State Hazard Mitigation Plan. Table 9 lists the incidences of wildfire for the four counties. In the nine-year period from 2004 to 2012, there were 805 wildfires. Table 9 Wildfire Summary by County County Wildfires Average Annual # of Wildfires Acres Burned Average Annual Acres Burned Total Buildings Damaged Clay Clinton , Platte Ray , ,004 Platte-Clay Area , ,039 3,007 Source: Missouri State Hazard Mitigation Plan 2013 Probability of Future Occurrence and Vulnerability The probability of wildfire is 100 % (805 events / 9 years). Since some fires crossed county lines, the average annual number of wildfires for the four counties is 290. The potential extent of damage caused by wildfire is difficult to determine. Like earthquakes and dam failure, wildfires have had no measurable impact upon the PCEC service area. In the nine-year period from 2004 to 2012, 805 fires have burned a total of over 9,352 acres, for an average annual of 1,039 acres burned. PCEC sustained no damage related to wildfires in its service area during this time period. Cooperative assets are located throughout the service area rather than being located at a single central site. With an average annual of 1,039 acres burned in the four-county area, and the total area of 1,173,120 acres it is unlikely that infrastructure damage would exceed 1% based upon asset location and unlikeliness of an uncontrollable wildfire. This assessment assumes a limited impact upon electric distribution infrastructure of less than 1%. No customers have reported outages in connection with wildfires between 2004 and When considering the total number of customers served by Platte-Clay, it can be projected that less than 1%, or 230 customers, may experience outages during any given wildfire event on an annual basis. Problem Statement Further study will be required to create a model for damage assessments related to wildfire. PCEC Page 16

17 Earthquakes Previous Occurrences The closest source of earthquake risk to Platte-Clay Electric is the Nemaha Fault, which runs roughly from Oklahoma City, Okla., north to Lincoln, Neb. In 1993, the Nemaha fault produced a discernable earthquake that was felt in the region, with magnitude of 2.9 on the Richter Scale of Earthquake Intensity. Additional quakes took place February 11, 1995 (3.1 magnitude); July 16, 2004 (3.5 magnitude); March 23, 2003 (3.1 magnitude), and December 17, 2009 (magnitude 3.6). Most recently on November 12, 2014, a magnitude 4.8 earthquake centered near Wichita, KS, was felt in northwest Missouri. The region is also subject to effects of the New Madrid Fault, located in extreme southeast Missouri, which has, according to many experts, the potential to produce the largest earthquakes in North America. This fault has the potential to affect the entire Platte-Clay service area. In addition, there have been several small, virtually undetectable earth movements in the region in recent history, which may or may not be attributed to these fault lines or other, very small faults located nearby. Probability of Future Occurrence and Vulnerability The New Madrid fault has the potential to cause damage throughout the state of Missouri and the Kansas City metro area served by Platte-Clay. Scientists from the U.S. Geological Survey (USGS) and the Center for Earthquake Research and Information (CERI) at the University of Memphis have estimated the probability of a magnitude 6.0 or greater earthquake from the New Madrid Fault is % through the year The projected earthquake intensity ratings for the cooperative s region change based upon the Modified Mercalli Scale. Given a New Madrid earthquake with a 6.7 magnitude, the region would experience Level V intensity characteristics. In the event of an earthquake with a 7.6 magnitude, the region would experiences Level VI intensity characteristics while an earthquake with an 8.6 magnitude would most likely cause Level VII intensity characteristics. In the event of an earthquake with a 7.6 magnitude, the region served by Platte-Clay area could be expected to experience minor building damage as well as damage to the electrical distribution system. Damage, however, would likely be relatively minimal and localized when compared with the southeast corner of the state. Distribution lines overhead and underground could become disconnected or severed, and transformers could be damaged. Though the probability of occurrence is very small, the potential extent of damage could significantly impact both the cooperative and its customers. Based upon information from CERI, FEMA and SEMA, it may be estimated that up to 2,000 customers could report outages related to an earthquake event. When compared with the total number of customers served by Platte-Clay, it can be projected that up to 10% of all customers may report outages during any given seismic event. Problem Statement PCEC should strive to meet seismic design standards for electrical substation equipment and other overhead assets susceptible to damage from earthquake events. PCEC Page 17

18 Dam Failure Like earthquakes, dam failures have had no measurable impact upon the Platte-Clay service area to date. According to Missouri DNR s Dam Safety Division, 272 dams currently exist within the cooperative boundaries: 32 in Buchanan County, 25 in Caldwell County, 41 in Clay County, 26 in Clinton County, 70 in DeKalb County, 29 in Platte County and 49 in Ray County. Of these dams, four in Buchanan County, one in Caldwell County, five in Clay County, four in Clinton County, 10 in DeKalb County, five in Platte County and five in Ray County are regulated by the state due to the fact that they are non-agricultural, non-federal dams which exceed 35 feet in height. Figure 6 shows the locations of all known dams located within Platte-Clay s service area. (Map sources: Figure 6 Platte-Clay Dam Map The most significant dam in the region is Smithville Lake, constructed by the U.S. Army Corps of Engineers in The dam is located in Clay County and Smithville Lake covers 7,190 acres and has a storage area of 102,200 acre feet. The lake drains 213 acres. Platte-Clay provides electric power to the dam, including the flood gates. PCEC Page 18

19 Previous Occurrences Twenty-six dam failures have occurred within the state of Missouri over the past 100 years. However, no such event has occurred within or near the cooperative s boundaries. Probability of Future Occurrence and Vulnerability For the purposes of this assessment, dam failure and its associated impacts cannot be eliminated from the realm of possibility. In order to allow for a risk assessment, the probability of this event has been included as less than 1%. Very localized damage would occur in the event of a dam failure, limiting its effect on PCEC s assets and its customers. Problem Statement Determining the potential extent of dam failure is currently limited due to a lack of data concerning inundation zones, although this information has or is scheduled to become available. Further study concerning existing dams and their impact is required to make a more comprehensive assessment of potential damages. An important consideration in regard to this hazard is the existence of large dams upstream on the Missouri River with millions of acre-feet of water storage. C. Risk Assessment Summary Most of the historical hazards have had an impact on the electric cooperatives. Table 10 below shows the annual damages associated with each hazard for PCEC. The table is ranked by the highest Average Annual Damages which is an indication of the vulnerability to each hazard. Table 10 Platte-Clay Electric Cooperative Hazard Risk Summary Hazard Average Annual Damages Tornadoes $36,577 Severe Winter Weather $22,500 Severe Thunderstorms, Hail and High Winds $11,720 Flood and Levee Failure $4,511 Dam Failure $0 Earthquakes $0 Wildfire $0 Each of the non-historical hazards Wildfire, Earthquakes and Dam Failure has the potential for causing catastrophic damages in any given year. To date there have been zero damages to the assets of the Platte- Clay Electric Cooperative from the non-historical events. Nonetheless, this set of hazards should be considered in mitigation strategies because of the damage potential. PCEC Page 19

20 Section 4: Mitigation Strategies Previous Mitigation Efforts For Platte-Clay Electric, mitigation is incorporated in daily business operations. In order to ensure the delivery of a quality product and minimize the service interruptions, a number of mitigation strategies are continually utilized. The cooperative seeks to minimize power outages as much as possible, while maintaining reasonable rates for customers. Platte-Clay Electric emphasizes mitigation efforts as the most efficient way to deliver a quality project and minimize service interruptions. Routine maintenance and upgrades to existing equipment is completed as part of daily tasks. Vegetation management, for instance, is a priority for the cooperative. Trees are inspected and trimmed over a cycle of six to eight years, depending on growth patterns. Safety and reporting information are disseminated to the public through various types of media, including newsletter, web site and social media. Mutual aid agreements and partnerships create relationships which provide for future support in the event of a natural disaster. Platte-Clay has undertaken the process of replacing aging overhead facilities. Portions of line are old and brittle and more likely to break in case of storm. The cooperative is replacing these sections with newer line as funding allows. Additionally, mitigation is considered prior to any expansion of service into special hazard areas. Before any service is built, it is staked out in coordination with local builders and property owners. This process identifies and addresses foreseeable hazards and safety issues before any new service lines are constructed. USDA-RUS specifications regarding operation and safety are utilized throughout the process. Steps are taken to minimize the exposure of equipment to loss due to foreseeable hazards, such as flooding. Existing and Potential Resources As stated above, mitigation is a key component of good business practices. Platte-Clay Electric includes mitigation strategies as part of regular work activities to ensure service with minimal interruptions. Funding for these activities is provided through the cooperative s normal budgetary process for maintenance. In order to expand mitigation efforts beyond normal maintenance, it is likely that Platte-Clay Electric will need to seek outside funding sources. These may include private, state or federal programs which provide grant and loan funding. Upon passage of this plan, PCEC will be eligible for funding through FEMA in the following categories: Hazard Mitigation Grant Program Flood Mitigation Assistance Program Pre-Disaster Mitigation Program 406 Stafford Act USDA Economic Development Grants PCEC Page 20

21 Review of Goals, s, and Actions Platte-Clay s mitigation staff reviewed the goals, actions, and objectives from the original plan which addressed hazard mitigation issues. They evaluated each action to decide if it was completed, will be continued, or should be deleted. There also was the opportunity to add goals, objectives or new actions. The staff considered which type of actions will maximize benefits and minimizes costs, how mitigation strategies will be implemented, and how the overall plan will be maintained and updated. Table 11 lists the original goals and objectives as presented in the 2012 plan, and in the last column, as reviewed in the 2017 plan update. Table 11 Platte-Clay Electric Goals and s Identified Goals-2012 Goal 1: Protect the health and safety of the community. Goal 2: Reduce future losses due to natural hazard events. Goal 3: Improve emergency management capabilities and enhance local partnerships. Goal 4: to promote public awareness and education. Identified s : Prevent injury, loss of life, and damage to property. 2: Reduce outage time to critical facilities. 1: Protect and maintain existing infrastructure. 2: Research and develop plans for future infrastructure improvements, seeking implementation where feasible. 3: Research and develop plans for future communication and data collection improvements where feasible. 1: Improve assessment of outages and reduce response time. 2: Create or maintain partnerships with outside agencies. 1: Utilize media resources to promote public education. 2: interaction with local schools and civic groups. Reassessment of the Goal/ Accept, as is Accept, as is Accept, as is Accept, as is Accept, as is Accept, as is Accept, as is Accept, as is Accept, as is Traditionally, the STAPLEE (Social, Technical, Administrative, Political, Legal, Environmental, and Economic) method is used to prioritize mitigation actions. These categories, however, do not necessarily align with the private sector in the same way they are applicable to governmental agencies. A number of action items could be included with multiple goals and objectives, for example. As a result, the cooperatives chose to use a different method to prioritize their mitigation strategy. After reviewing ongoing and potential action items, the action items were placed in one of three priority tiers: PCEC Page 21

22 First tier actions focus on physical infrastructure protection and improvements which ensure continued, quality service and seek to reduce power outages. These types of actions are the highest priority of Platte-Clay Electric. Second tier actions create and maintain working relationships to reduce and prevent the impact of power outages. These include improvements to safety and reporting information, mutual aid agreements and other efforts which seek to expand and improve both customer service and disaster planning. Third tier actions identify potential projects for other system improvements. These include mapping efforts, technological improvements, and research related to the expansion of mitigation efforts. Actions within each tier may be funded through regular budgetary methods or identified outside sources. The final component of reviewing the proposed and existing mitigation strategies was to perform a costbenefit analysis of all mitigation actions. The analysis was based on past experiences of performing certain actions and the potential number of beneficiaries. The following matrix, Table 12, was used to rate each mitigation action. Cooperative staff was asked in the Goals, s and Actions Survey to review the cost-benefit rating and change if necessary. Table 12 Cost Benefit Matrix COST BENEFIT High Medium Low High Medium Low The following tables represent the completed 2017 review of current and potential mitigation strategies. Each strategy has assigned a cost benefit score assigned by the cooperative staff based on prior experience and professional opinions. Tables 13, Table 14, and Table 15 provide lists of action items by tier (1, 2, and 3 respectively), the goals and objectives identified with each, and the results of the cost-benefit analysis. The tables have been updated through the Goals, s and Actions Survey that was sent to Platte-Clay Electric to facilitate the staff update review. The Survey can be found in Appendix C. Staff members reviewed each item on the original tables and determined the current status of the item. The Hazards Addressed by This Action column was not included in the 2012 plan; this information has been added into the 2017 plan update for each Action Item. PCEC Page 22

28 Section 5: Plan Implementation and Maintenance Plan Incorporation The goals, objectives, and actions of the previous section identify both ongoing efforts at mitigation and potential methods for expanding efforts. The updated plan has been reviewed and adopted by the Board of Directors as part of the company s operations policy. This mitigation plan necessitates involvement from every Platte-Clay Electric employment level as the organization strives to ensure quality service to their customers. Local Planning Capabilities Some internal planning capabilities do exist at Platte-Clay. The Hazard Mitigation Plan can be considered and/or incorporated into regular budgetary planning, the four-year work plan for capital improvements, and the maintenance planning policy. Planning capabilities per se for the electric cooperatives are limited. What is important is that the Action Items developed through the mitigation planning process are incorporated into the daily activities of the cooperative. The four year work plans embrace the mitigation efforts that are in the mitigation plan. The electric cooperatives across Missouri are always working to strengthen their systems. This would include installing stronger/larger poles when smaller ones need to be changed out, installing stronger/larger conductors that can carry more weight and decreasing span lengths between poles, installing larger anchors, relocating structures out of flood plains, and installing structures to stop cascading during ice storms. Other capabilities are unique to the electric cooperative s business of providing reliable electricity to their members. Many of the Action Items listed in the plan include tree trimming plans, use of GPS to locate outages, service upgrades to lines and poles, warning systems and use of weather radios, collection of GIS data and utility specific software for locating and rerouting outages to restore power, all contribute to local capabilities. Integration of Platte-Clay s planning with local law enforcement, mutual aid agreements, and partnerships with local emergency management resources ensures power to critical facilities during a hazard event. This coordination and cooperation broadens the capabilities of the local cooperative. Beyond the Platte-Clay Hazard Mitigation Plan, regional planning capabilities exist at the local level. The Missouri counties of Buchanan, Caldwell, Clay, Clinton, DeKalb, Platte and Ray each have a FEMAapproved Natural Hazard Mitigation Plan in place. The counties of Buchanan, Caldwell, Clay, Clinton, Platte and Ray have planning and zoning regulations. DeKalb County is a third class county that does not have planning and zoning, but townships have planning and zoning regulations. County emergency management directors have Local Emergency Operations Plans which seek to mitigate the same hazards for residents. These same counties are also included in the Regional Transportation Plan (RTP) as well as a Comprehensive Economic Development Strategy (CEDS). Platte-Clay Electric s plan can be incorporated into these local plans and allow for coordination across agencies in the event of an emergency. PCEC Page 28

29 Plan Maintenance Platte-Clay Electric will follow the requirements coordinated by the Association of Missouri Electric Cooperatives (AMEC) for monitoring, evaluating, and updating the plan. d Public Involvement Opportunities Public notice was given in the form a notice in the Rural Missouri, a publication of the Association of Missouri Electric Cooperatives, distributed to all cooperative members. The updated 2017 plans were posted on the website of the Northwest Missouri Regional Council of Governments for public review and comment. Comments were considered and addressed. Once all co-op plans were completed, they were assembled into one plan and submitted to the State Emergency Management Agency and the Federal Emergency Management Agency for review and approval. The documentation for public involvement and comments can be found in Appendix B of each cooperative s section of the plan. Platte-Clay Electric will follow the requirements coordinated by the Association of Missouri Electric Cooperatives (AMEC) for continued public involvement. Opportunities for public comment will continue to be offered through various media outlets and the physical office of Platte-Clay. PCEC Page 29
