The Coast Guard is required to develop, establish, maintain, and operate rescue facilities for the promotion of safety and may aid distressed persons, and protect and save property in waters subject to the jurisdiction of the United States. To carry out its responsibilities, the Coast Guard maintains a search and rescue system on the Atlantic, Pacific, and Gulf coasts; the Great Lakes; and other inland lakes and waterways. This system consists of about 190 boat stations, 183 of which are located in the contiguous United States. The Coast Guard also operates aircraft from 24 air stations and four air facilities. As of August 2017, these stations and facilities operated about 700 boats and about 200 aircraft. In fiscal year 2016, the Coast Guard reported that its SAR operations saved 5,174 lives and protected more than $63 million in property from loss. The Coast Guard’s boat stations, air stations, and air facilities are subject to laws which require the Coast Guard to maintain specific minimum capabilities—such as a requirement to maintain at least one vessel at each station that is fully capable of operating within the prevailing weather and marine conditions in that station’s area of responsibility. In addition to maintaining capabilities requirements, if the Coast Guard reevaluates its station location needs and intends to close a boat station, air station, or air facility, it also must follow a statutorily defined process, which includes making a determination that adequate SAR coverage will remain in place. To close an air facility, the Coast Guard must also submit a proposal to close the facility to Congress in the President’s annual budget and notify members of Congress who represent the impacted communities, as well as certain committees. The Coast Guard’s field structure is divided into two Area Commands, Atlantic and Pacific, within which are nine Districts consisting of 37 Sectors and the stations within them (see figure 1). Stations are traditionally associated with search and rescue but they may perform the full range of Coast Guard missions. Coast Guard personnel live and work at or near their stations so they can rapidly respond to emergencies as they arise. This model facilitates the Coast Guard’s search and rescue response resource planning standard. Under this SAR standard, Coast Guard plans for its units with SAR responsibilities to arrive on the scene of a case within 2 hours of receiving a distress call. Stations vary in their mission mix and pace of operations (i.e., operational tempo) by geographic region or District, and by season. For example, Coast Guard boat stations in D7 (Florida, Puerto Rico, South Carolina, and the Caribbean) commonly conduct migrant interdiction operations, whereas boat stations located along the Great Lakes (D9) rarely conduct this mission. In some locations, SAR cases may be more common during the summer boating season than in the winter. Stations in D9 have a shorter boating season than stations in D7. According to Coast Guard officials, while D7 has more total SAR cases than D9, cases in D9 are concentrated in a shorter time period than in D7 (i.e., shorter boating season). Boat stations also vary widely in size and function. For example, Station New York in New York City has an authorized strength of 88 personnel, whereas Station Frankfort in Frankfort, Michigan, has an authorized strength of 15 personnel. Both stations perform SAR and other missions, but Station New York also conducts a high level of homeland security missions, while Station Frankfort provides ice rescue capability during the winter. Additionally, the Coast Guard operates 18 seasonal boat stations called “Stations (Small),” which are detached subunits of larger parent stations; the Coast Guard generally operates these during the summer boating season. When the Coast Guard receives notification of a distressed mariner, a search and rescue mission coordinator evaluates the case and assigns assets, such as boats or aircraft, to respond. Cases may involve multiple assets depending on the complexity of the case, such as the need to locate a mariner whose position is only generally known or to operate in severe weather conditions. Figure 2 depicts the general steps for conducting a SAR case. The Coast Guard uses several different types of assets to carry out its search and rescue and other missions. These assets include boats, rotary wing aircraft (helicopters), fixed wing aircraft (planes), and cutters (including patrol boats and ships). Additional details regarding some of these assets, including boat speeds, are described in appendix II. Over time, the need for Coast Guard stations at particular locations has changed due to changes in Coast Guard asset capabilities, boating activity, boating equipment, safety technology, and the capabilities of other search and rescue service providers, such as private towing firms. However, the Coast Guard’s decisions to close or reduce operations at boat stations based on changing conditions or budget reductions have been sensitive. We previously reported that these sensitivities were based on the perception that reducing operations or closing stations would reduce the agency’s ability to save lives and property. In 1990, we reported that the Coast Guard’s attempts to close stations in 1988 were not successful because the Coast Guard did not have policies or procedures for what criteria should be used or how the criteria should be applied, and because the Coast Guard applied its evaluation criteria to a limited universe—only 34 stations instead of all stations. We also found that the Coast Guard did not adequately address how closing stations would impact the Coast Guard’s effectiveness in saving lives or performing other missions. In 1994, we reported that the Coast Guard had created a new process for determining the need for boat station changes. We also found that the new process included detailed criteria to evaluate the appropriate need for stations, such as boating and economic trends and the availability of alternative SAR resources. The Coast Guard then unsuccessfully attempted to close stations in 1995 using this process, and again in 2008, efforts which we describe later in this report. In 2010, federal law required that we identify programs, agencies, offices, and initiatives with duplicative goals and activities within departments and government-wide, and report annually. The annual reports describe areas in which we have found evidence of fragmentation, overlap, or duplication among federal programs and have resulted in $136 billion in financial benefits for the federal government. Figure 3 outlines the definitions we have used since 2011 in our work to address fragmentation, overlap and duplication. The Coast Guard has a sound process for analyzing the need for boat stations that is consistent with GAO’s Program Evaluation guidance, which calls for choosing well-regarded criteria against which to make comparisons in order to achieve strong, defensible conclusions. The primary criteria Coast Guard subject matter experts established, consistent with statutory requirements that the Coast Guard make a determination that adequate SAR coverage would remain in place, were (1) a minimum threshold of overlapping SAR coverage had to be maintained and (2) the Coast Guard’s ability to meet its nationwide 2-hour SAR response standard had to be maintained. By applying these criteria, the Coast Guard’s process identified overlapping search and rescue coverage where three or more stations can respond to a single SAR case within 2 hours, and unnecessary duplication where stations could be closed without negatively impacting the Coast Guard’s ability to meet mission requirements, such as its 2-hour SAR response standard. In June 2012, the Coast Guard established a Station Optimization Process Charter that called for the Coast Guard to develop a defendable process with criteria for analyzing stations for potential closure. The charter stated and Coast Guard officials confirmed that the process was developed to ensure that closure recommendations would be based on solid justifications for stations selected, and would stand up to rigorous scrutiny. The charter called for (1) the process to be data driven; (2) criteria to be applied consistently; (3) consideration of previous GAO recommendations on assessing stations for closure; and (4) adherence to statutory requirements to conduct outreach to affected communities. The Coast Guard then established a working group of subject matter experts who developed a Station Optimization Process with nine analytical steps. The Station Optimization Process included criteria for analyzing the need for boat stations based on data analysis, consistent application of criteria, and legal requirements. Figure 4 shows the Station Optimization Process and its nine steps. In April 2013, the Coast Guard initiated its 9-step Station Optimization Process to analyze its boat stations, and the results identified 18 stations that could be closed because they provide overlapping and unnecessarily duplicative SAR coverage. The Coast Guard hired a contractor to carry out the analysis and identify potential cost savings from permanent closures of such stations. Although focused on SAR coverage, the process also included consideration of all Coast Guard missions carried out at these stations. The contractor followed the 9-step process, with certain steps conducted by the Coast Guard––such as step 1, which analyzed the system and identified overlapping SAR coverage––and developed and ranked different closure options to maximize cost savings. Coast Guard officials provided additional district input on unique characteristics of certain stations to further refine the closure options. The final study identified 18 stations for closure that it estimated would achieve cost savings without impeding the Coast Guard’s ability to meet its SAR response standard and carry out its other missions. We discuss this further later in this report. The Coast Guard considers some overlap or redundancy to be necessary, to account for such things as operational challenges, boat maintenance downtime, personnel training requirements, and the need for surge capacity to respond to certain incidents. Therefore, the Coast Guard directed the contractor to analyze areas with triple or greater station coverage as its baseline for analyzing whether stations were unnecessarily duplicative. Based on the Coast Guard’s review of this coverage, it determined that the greatest extent of overlapping coverage existed in Districts 1, 5, and 9, and directed the contractor to focus on stations in those areas. Figure 5 shows the extent of overlapping Coast Guard boat station SAR coverage as of September 2013 that was used for the contractor study and is still accurate as of May 2017. It shows for Districts 1, 5, and 9, up to quadruple or greater SAR coverage provided by boat stations with overlapping response capabilities. According to the Coast Guard, in an attempt to be conservative in maintaining SAR coverage, the optimization process did not consider the use of Coast Guard air assets such as helicopters—an additional layer of coverage— nor did it consider the availability of some local agencies that respond to SAR cases, such as police departments and emergency responders. Therefore, overlapping coverage depicted in figure 5 excludes air asset responses and any responses or assistance provided by state and local agencies. The extent of coverage in 2017 was the same as the Coast Guard’s 2013 contractor study reported. We determined that the actions taken to complete the station optimization process are sound, consistent with our Program Evaluation guidance which calls for, among other things, evaluating programs based on well- regarded criteria to achieve strong, defensible conclusions. In addition to using the 2-hour response standard as a criterion, the optimization steps identified actions to systematically analyze quantitative measures using a documented ranking system to remove critical stations from consideration for closure. For example, step 4 of the process evaluated the number of security boardings conducted by selected stations, among other metrics, and removed certain stations for consideration from closure based on a systematic application of criteria related to other mission responsibilities. Further, as described in table 1, the process began with consideration of all boat stations in the contiguous United States, included steps to ensure that data were reliable and appropriate, clearly identified limitations of the analysis, and conducted simulations to assess how well the Coast Guard would be prepared to carry out its responsibilities under different closure alternatives, such as whether a station closure reduces or changes the Coast Guard’s ability to meet its response standard—all actions included in our Program Evaluation guidance. Table 1 provides details of actions taken by the contractor and the Coast Guard to complete the 9-step station optimization process. Consistent with the 9-step optimization process and to validate the closure scenario results, the contractor and Coast Guard Headquarters obtained regional input from district officials to gain context about the stations under consideration for closure such as unique rescue characteristics that were not quantifiable. Coast Guard officials within Districts 1, 5, and 9 generally supported the contractor recommendations to close some stations, with a few exceptions. For example, District 1’s input stated that one station recommended for closure by the contractor analysis had a unique surf rescue capability that was not available at adjacent or other nearby stations and thus this station did not provide unnecessarily duplicative SAR coverage since no nearby station could provide this capability. Thus, District 1 recommended that the station remain open. Given this input, the contractor removed this station from consideration for closure. In another example, District 5 officials reported that closure of one of its stations would increase response times from adjacent stations due to the presence of shoaling and barrier island conditions that could not be accounted for in the quantitative modeling. Therefore, the contractor eliminated that station from consideration for closure and recommended an alternative station for closure. This process of obtaining regional input and validation from district officials was carried out such that if a station identified for closure would negatively impact critical missions, it was removed from closure consideration. This additional district input resulted in a final contractor study that recommended station closures that would achieve the greatest cost saving without negatively impacting the Coast Guard’s ability to meet mission requirements. In addition to identifying stations with unique characteristics that warranted keeping them open, additional district input also confirmed contractor recommendations that some stations should be permanently closed. For example, District 5’s input concurred with the closure of six stations, including one where officials we interviewed on site confirmed its steadily diminishing SAR caseload. Our analysis of Coast Guard data validated this station’s low workload showing an average of seven single- boat response SAR cases annually from fiscal years 2010 through 2016. We also found that this station had been recommended for closure in the past. In another example, District 9 input sought an additional, seasonal closure of one station that the contractor analysis did not evaluate for permanent closure due to one criterion applied by the process. District 9’s input provided additional context for this station, saying that seasonal closure was preferable to taking no action because there was significant response redundancy in this region. Moreover, the district input noted that the acquisition of modern boats has increased the range and reduced the response time of many stations. District input also noted that improvements in public education and awareness of safe boating practices, technology and availability of communications equipment, and the increase in non-Coast Guard response resources has resulted in a steady and dramatic decline in the stations’ SAR workloads. Our analysis of all Coast Guard single-boat response data for cases within the contiguous United States for fiscal years 2010 through 2016 confirmed this decline, showing an annual average of 46 cases per station in 2010 to an annual average of 39 cases per station in 2016, a decline of about 15 percent. Appendix IV provides details from our analysis of the number of single-boat response SAR cases conducted by selected stations. In 2014, the Coast Guard contracted for an analysis of selected air stations and air facilities that identified overlap and unnecessary duplication but it did not comprehensively review all air stations and air facilities. Specifically, the criteria-based analysis reviewed search and rescue capabilities, operational case data, and other mission requirements, and determined that certain air facilities provided overlapping search and rescue coverage, some of which was unnecessarily duplicative. Coast Guard officials said they used the results of this analysis to support proposed closures of air facilities in Newport, Oregon, and Charleston, South Carolina, in the President’s Fiscal Year 2014 Budget. Subsequent appropriations for fiscal year 2014 also did not include funding for the operation of the two air facilities. However, shortly before their planned closure date, the Coast Guard encountered strong opposition to the closures at the local, state, and Congressional levels, and did not close them. As with boat stations, the Coast Guard considers some overlapping coverage among air stations and air facilities desirable to mitigate potential risks such as those posed by asset maintenance downtime, limitations in the number of qualified personnel, restrictive weather conditions, or case complexity. Coast Guard officials stated that the 2014 analysis considered many factors to address potential impacts of the closure of the Newport and Charleston air facilities. For example, the Coast Guard used modeling tools to determine the operational impact of altering facility locations and the availability of aviation assets. Coast Guard officials told us they also conducted outreach to the affected communities and their political representatives in advance of the proposed closure date, as required by law. Further, Coast Guard officials explained that the fiscal outlook at the time (e.g., sequestration) required changes to optimize assets, and their proposal accomplished this without sacrificing operational capability because the response time of neighboring SAR units would remain within the Coast Guard’s SAR standards. The 2014 analysis also determined that the majority of SAR cases involving these two facilities occurred close to shore, with boat responses generally arriving on scene and conducting the search and rescue instead of air assets. Circles in figure 6 represent air asset response capabilities nationwide, as of August 2017, with darker shades reflecting greater overlapping coverage. In 2014 and 2016, two laws were enacted that required the Coast Guard to keep the air facilities open for a specific period of time, and established a number of requirements the Coast Guard is required to follow if it proposes closing or terminating operations at its air facilities. Thus, the two air facilities remained open. As of May 2017, Coast Guard officials told us they have no plan to close air facilities or air stations, nor do they plan to develop a process to comprehensively review air stations or facilities to optimize their locations because previous attempts to close stations or facilities have been prohibited by law or subject to certain requirements. However, the Coast Guard has responsibility for evaluating the need for its air stations and air facilities to ensure that it is using resources as effectively and efficiently as possible. The Coast Guard’s station optimization charter calls for a defendable (i.e., sound) and data- driven analysis of boat stations that meets statutory requirements. This charter could be a template for establishing a parallel process for comprehensively analyzing the need for its air stations and air facilities. GAO’s Program Evaluation guidance calls for evaluating programs based on well-regarded criteria to achieve strong, defensible conclusions. Program evaluations can also provide accountability for the use of public resources (e.g., to determine the “value added” by the expenditure of those resources), such as whether scarce resources are being spent on unnecessarily duplicative air facilities. Having a sound and reproducible process for comprehensively analyzing the need for air stations and air facilities will better position the Coast Guard to make decisions to enhance the efficiency of its operations and more effectively allocate its resources. These actions will also better inform Congress as to the status of the Coast Guard’s resource needs and the efficiency of its operations. The 2013 analysis of Coast Guard stations identified unnecessary duplication and recommended certain stations for potential closure; however, as of August 2017 the Coast Guard had not closed any stations, nor developed a plan with time frames for closing stations. In their input to the station optimization process, Coast Guard officials in affected districts supported recommended station closures to achieve operational improvements, and Coast Guard leadership continues to believe the study results are valid. Implementing station closures could also result in costs savings. The need to close some Coast Guard stations that provide unnecessarily duplicative SAR coverage to efficiently respond to changed circumstances such as improved technology is not a new issue. Coast Guard officials reported, and our prior work has shown, that the Coast Guard has attempted to permanently or seasonally close stations at least eight times since 1973. However, closing unneeded stations has historically been difficult due to public concern about the effect of closures on local communities and other factors. In some cases over the years, Congress has intervened and enacted federal laws that have affected Coast Guard’s proposed closures. For example, in 1988 the Department of Transportation and Related Agencies Appropriations Act, 1989, required the Coast Guard to reopen boat stations 1 year after they had been closed, and at the same time provided that GAO was to evaluate the methods behind the Coast Guard decision. Responding to this provision in 1990, we reported that the Coast Guard’s 1988 closure decisions were based on flawed methods, incomplete analysis, and incomplete data. The Coast Guard subsequently updated its process and by 1994 we reported that that it was using a reasonable approach to recommend stations for closure. Despite the improved Coast Guard process, no stations have been closed since 1988. Coast Guard officials reported that Congress continues to oversee and manage the closure of stations, such as by establishing new requirements in the Coast Guard Authorization Act of 1996, which must be met to change any boat stations, after the Coast Guard attempted to close 23 stations in 1995. Similarly, after the Coast Guard attempted to close two air facilities in 2014, legislation was passed in 2014 and 2016 that prohibited Coast Guard air facility closures until January 2016 and 2018, respectively. Figure 7 provides a timeline of Coast Guard station change proposals or actions, including at least eight Coast Guard attempts to close stations between 1973 and 2014. The figure also includes statutory requirements established in 1989, 1996, 2014, and 2016, and two data-driven analyses and studies with recommendations to address unnecessary duplication, among other information. Past Coast Guard efforts to analyze and close stations have frequently identified the same stations as candidates for closure. For example, prior to the 2013 contractor study, at least two Coast Guard districts conducted their own station analyses to identify opportunities to improve their stations’ operations. These analyses also recommended permanent and seasonal closures of some stations. Specifically, in 2010, Coast Guard District 9 began conducting a data-driven analysis of its stations to optimize its boat forces. District 9 officials told us they initiated the analysis due to budget constraints, the challenges they had in fully staffing their stations, and their awareness of overlapping SAR coverage within the district. District 9’s analysis reviewed more than 16,000 SAR cases over a 5-year period (2008–2012) to understand and quantify potential response inefficiencies. According to Coast Guard officials, their analysis determined that overall SAR caseload in District 9 was extremely high in the summer months, but there was little or no SAR caseload for some stations during the winter, a factor which also affected training proficiency as personnel were not able to respond to enough cases to maintain required qualifications. Based on the results of this analysis, in December 2012, District 9 requested approval to permanently close five stations and seasonally close three stations to achieve more effective operations and improve maritime safety in the Great Lakes region. According to Coast Guard district officials, these recommended closures provided no calculated savings to taxpayers because they involved movement of personnel positions and assets to other stations, not their elimination. Instead, the recommendations showed an effort to improve operational efficiency and conserve Coast Guard resources. Furthermore, among those stations in Districts 1, 5, and 9 recommended for permanent closure in 2013, at least five—Ashtabula, Ohio; Frankfort, Michigan; Harbor Beach, Michigan; Shark River, New Jersey; and Block Island, Rhode Island—were also recommended for closure between 1985 and 1988. When we compared the 2012 recommendations from the District 9 analysis, the 2013 contractor analysis recommendations that used the 9- step Station Optimization Process, and additional 2013 district input, we found similar results among the various analyses with respect to which stations should be permanently or seasonally closed. Based on our review of documentation and interviews with District 9 officials, as well as our comparison of the results of the District 9 analysis with the results of the contractor analysis, the 2013 recommendations are affirmed by the District 9 analysis. We provide a comparison of selected recommendations and Coast Guard Headquarters’ tentatively planned actions in table 2. Input from District 9, which had the greatest number of affected stations in the 2013 analysis, supported recommended changes and stated that “the existing unnecessary redundancies, unsustainable complexities, and unacceptable resource gaps negatively affected mission execution in the Great Lakes, where staffing shortfalls exist.” District 9’s input further stated that in some regions, four stations could respond to SAR cases within the Coast Guard’s SAR standard, and that while some redundancy is merited, these areas demonstrate redundancy that is operationally unnecessary, inefficient, and detrimental to the training needs of station personnel. Our interview with officials at one affected station confirmed some of the complexities facing the region. For example, officials told us that because one station recommended for seasonal closure does not operate a boat capable of offshore SAR responses, adjacent stations are already directed to respond to certain offshore SAR cases in that station’s area of responsibility to meet the Coast Guard’s 2-hour SAR standard. Officials we interviewed from each of the seven stations we visited in District 9 noted their station’s high SAR caseload concentration during the summer months and the low or nonexistent SAR caseload during the winter. For example, officials from two stations that the Coast Guard would like to seasonally close during the winter told us that their stations had not responded to an ice rescue in more than 7 years. Officials we interviewed at one station recommended for permanent closure noted that commercial boating traffic and the local population have been declining for many years, that the station was not busy during the winter season, and that the station had not conducted an ice rescue since 2002. In 2017, the Coast Guard affirmed that its leadership believed that the results of the 2013 study remained valid as station workloads have remained relatively consistent. Headquarters officials also told us that the 2013 study criteria and subsequent recommendations for permanent closures were conservative because of previous unsuccessful attempts to close stations, and to meet statutory requirements to maintain a certain level of SAR coverage. They also told us that the analysis did not consider additional layers of response even though these layers could provide some additional SAR response backup for Coast Guard stations. For example, the contractor’s analyses of boat stations did not consider SAR support provided by Coast Guard aviation assets, which generally provide an additional layer of SAR coverage for boat stations. Moreover, district officials told us that aviation assets in District 9 were recently realigned to provide even greater response capability, including longer range helicopters with de-icing capability to improve winter response capability. The contractor analysis also did not take into account the potential SAR capabilities of commercial towing operators and local first responders which can also provide another layer of coverage to assist Coast Guard stations with SAR coverage. For example, officials from each of the seven stations we visited in District 9 told us that they coordinate with other entities, such as commercial towing operators, who can conduct responses for non-life-threatening incidents, such as providing fuel to or towing disabled boats in their station’s area of responsibility. Officials from one station also told us that the local fire department has performed ice rescues in the past, because people who require ice rescues tend to dial 911 first rather than call the Coast Guard, and thus local emergency responders are able to respond faster than the Coast Guard. Officials from another station told us that the local sheriff has two response boats, and that the Coast Guard coordinates with local government and responders. Station closures could also achieve cost savings in addition to the aforementioned efficiency improvements. For example, based on our analysis of the contractor study, if its recommendations to permanently close the 18 stations from D1, D5, and D9 were implemented, and personnel and boat assets were moved or reduced in accordance with the study recommendations, the study reported that these closures could achieve potential cost savings of about $290 million over 20 years. In addition, land disposition estimates were excluded from the study, which could result in one-time proceeds from the sale of the land on which the stations are sited, if the land value exceeded remediation costs. In addition to lost opportunities to improve operational efficiency and effectiveness because stations were not closed previously, some of these stations have also fallen into physical disrepair and will require funding for repairs if the stations remain open, even if they are only operated seasonally. For example, officials at one station we visited showed us a boat dock that was improperly installed and thus was subsequently damaged by waves and will need to be repaired or replaced. At this same station, officials informed us that the furnace system requires daily, manual adjustments to address temperature fluctuations that could cause damage to the station. One official also told us that this station’s building structure is too big and costly, and its condition too poor, to be worth keeping. Therefore, even if this station were seasonally closed, as currently recommended—despite the analysis results suggesting permanent closure—the station will continue to require personnel to be at the station on a daily basis year round. Another station, which multiple studies recommended for permanent closure because of unnecessary duplication and a caseload insufficient to sustain the training requirements of personnel stationed there, was rebuilt as a result of extensive damage from Hurricane Sandy. According to Coast Guard budget data, more than $2.3 million was expended to restore this station as of March 2017 using funds appropriated by the supplemental appropriations act enacted in response to Hurricane Sandy. Given the extent of overlapping SAR coverage identified by the Coast Guard’s analyses and its attempts to address unnecessary duplication, we considered the stations’ levels of overlapping coverage in the context of the definitions we use for identifying overlap and duplication. Figure 8 depicts the extent of the Coast Guard’s overlapping boat and air station SAR coverage, with darker shading representing greater overlapping coverage, some of which the Coast Guard determined to be unnecessarily duplicative. Boat station coverage is represented by shading while aviation coverage is shown by the largest circle sizes. In April 2016, the Coast Guard completed statutory requirements associated with closing eight stations in District 9 by conducting outreach to regional and local communities that would be affected by seasonal closures. The Coast Guard held these meetings to explain why it was necessary to optimize station locations and reallocate personnel from closed stations to their adjacent stations; address overlapping SAR coverage; and seasonally close unnecessarily duplicative stations. Coast Guard officials from one station told us they held a public meeting with the local fire department, police, and commercial towing operators to describe planned changes for seasonal operations at the station, despite this station having been recommended for permanent closure by studies and district input. According to Coast Guard officials, while some local responders in the District 9 area expressed some concerns, they understood the need for change. In addition, according to headquarters officials, the Coast Guard has also completed outreach efforts with members of Congress who represent these communities. They further stated that they plan to follow the same outreach process when they finalize decisions about whether to permanently or seasonally close stations in Districts 1 and 5. The Coast Guard has not taken action to implement the results of its analyses which recommended closures even though it has completed requirements to pursue station closures in District 9. Officials stated that the Coast Guard has not implemented the results of its sound process because past station closure efforts have been met with resistance from affected communities. As a result, Coast Guard leadership decided to pursue a more cautious approach by maintaining seasonal daily operations rather than closing stations outright as recommended in multiple analyses. Standards for Internal Control in the Federal Government state that agencies should have policies and procedures for ensuring that findings of audits or other reviews, such as the Coast Guard’s 2013 station optimization study, are promptly resolved. The guidance further states that managers are to (1) correct identified deficiencies, (2) produce improvements, or (3) demonstrate that the findings and recommendations do not warrant management action. Coast Guard officials stated they recognize that their planned actions do not fully match the identified recommendations, but given historical challenges with closing stations, seasonal closures are preferable to taking no action. In March 2017, Coast Guard officials told us they intended to begin the process for seasonal closures of stations in District 9 at the end of the 2017 boating season while actions in Districts 1 and 5 are pending as the Coast Guard has not finalized its decisions about these stations. The Project Management Institute’s Standard for Program Management describes, among other things, how resource planning, goals, and milestones are good practices that can enhance management for most programs. By executing decisions to close stations based on the results of its analyses and developing a plan with milestones to execute actions it has identified to address unnecessary duplication, the Coast Guard will be better positioned to follow through with both permanent and seasonal closures of unnecessary stations, can improve its operational and training proficiency by consolidating the remaining stations’ workloads to allow for sufficient training, and may realize cost savings. The Coast Guard’s 2013 analysis, based on a sound, data-driven process that applied established criteria—its 2-hour SAR response standard— supports permanently closing some boat stations. Nevertheless, Coast Guard officials do not intend to follow the recommendations to permanently close the stations the study recommended, due, in part, to views expressed by community representatives. The Coast Guard’s 2014 air station and air facilities study also supported closing two air facilities and was criteria-based, but was not comprehensive. An optimization process similar to that applied to boat stations could make a better case for closing selected air stations and air facilities, if it is methodologically sound. The need to close Coast Guard stations that provide unnecessary duplication of SAR coverage, in response to changing circumstances, is not a new issue. Closing unneeded stations has historically been difficult, but with improvements in technology, severely decreased workloads, and continuing budget constraints, the importance of reevaluating the operations of these stations is even greater. In addition to lost opportunities to improve operational efficiency and effectiveness that would be gained by closing unnecessary stations, some of these stations have fallen into physical disrepair and will require funding for repairs if they remain open. Given these factors, Coast Guard action is clearly warranted. We are recommending the following three actions to the Coast Guard: The Commandant of the Coast Guard should establish and follow a sound air station optimization process similar to its process for analyzing boat stations to allow it to comprehensively analyze its need for air stations and air facilities and determine what changes may be needed. (Recommendation 1) The Commandant of the Coast Guard should establish a plan with target dates and milestones for closing boat stations that it has determined, through its 9-step process and subsequent analysis, provide overlapping search and rescue coverage and are unnecessarily duplicative. (Recommendation 2) The Commandant of the Coast Guard should take action to close the stations identified according to its plan and target dates. (Recommendation 3) We provided a draft of this report to DHS for review and comment. In its comments, reproduced in appendix V, DHS concurred with our recommendations. DHS, through the Coast Guard, also provided technical comments, which we incorporated as appropriate. DHS concurred with our first recommendation that the Coast Guard establish and follow a sound air station optimization process similar to its process for analyzing boat stations so it may comprehensively analyze its air station and air facility needs. DHS further stated that the Coast Guard would utilize its fiscal year 2020 Planning, Programming, Budget, and Execution cycle to identify efficiencies in air station optimization using best practices employed in its boat station optimization efforts. DHS expects this effort to be completed in September 2019. DHS concurred with our second recommendation that the Coast Guard establish a plan with target dates and milestones for closing boat stations that it has determined provide overlapping search and rescue coverage and are unnecessarily duplicative. DHS stated that Coast Guard headquarters and appropriate district commands will continue to analyze operational coverage across the nation through the 9-step optimization process and recommend closures or seasonalization (e.g., seasonal closures) of boat stations to eliminate unnecessary duplication and overlap in search and rescue coverage. The Coast Guard’s internal analysis is expected to be completed in September 2020. DHS concurred with our third recommendation that the Coast Guard take action to close the identified stations according to its plan and target dates, stating that Coast Guard headquarters personnel and appropriate district commands will continue to analyze closing or seasonalizing operations at boat stations identified according to its plan and target dates. DHS further stated that it must complete implementation of the second recommendation before beginning to implement the third and that the estimated completion date for the third recommendation was to be determined. Given the robustness of the Coast Guard’s review process and the clear results showing unnecessary duplication among some boat stations, in addition to other valid analyses completed in previous years supporting the closure of unneeded boat stations, the Coast Guard should move forward with minimal delay to implement this third recommendation, once the plan as outlined in the second recommendation is completed. We will continue to monitor the Coast Guard’s actions to close unnecessarily duplicative stations in a timely manner through our annual report on duplication, overlap, and fragmentation in the federal government. We are sending copies of this report to the appropriate congressional committees, the Secretary of the Department of Homeland Security, and other interested parties. In addition, the report is available at no charge on the GAO website at http://www.gao.gov. To identify the extent to which the U.S. Coast Guard (Coast Guard) has a sound process for analyzing the need for its boat stations, we reviewed laws, policies, and procedures related to its search and rescue (SAR) mission. We reviewed Coast Guard documentation of processes it used to analyze the need for boat stations, reviewed resource and budget factors, and analyzed station activity levels. We also reviewed prior GAO reports on the Coast Guard’s resource allocation process and its previous attempts to close stations. To verify and validate the Coast Guard’s specific analytical process used to determine overlapping coverage, we obtained and analyzed the Coast Guard’s analytical assumptions, including the operational parameters of the assets assigned to the stations (e.g., boat speeds), and station locations. This analysis also allowed us to verify the soundness of the Coast Guard’s model used to identify overlap. We then independently recreated and visually depicted overlapping SAR coverage provided by the stations, based on Coast Guard data, assumptions, and documentation, and compared it with SAR case data by geographic area. We then analyzed Coast Guard data on single boat SAR responses (sorties) by station for fiscal years 2010 through 2016, the most recent data available at the time of our review. We visited a nongeneralizable sample of 12 stations we selected from within districts where the Coast Guard had identified overlap, and interviewed officials to identify local policies, station characteristics, local coordination with emergency responders and federal agencies, and local input to the Coast Guard’s process for assessing station needs and implementing changes to the locations of stations, if any. Additionally, we interviewed Coast Guard officials, including field and headquarters personnel, to determine the extent to which the Coast Guard had assessed maritime activity trends and leveraged resources from outside entities, such as local first responders, federal agencies, and private industry. We also interviewed Coast Guard officials to obtain information on the extent to which the Coast Guard used findings and recommendations from selected studies, strategies, and plans in its analyses of the need for its boat stations. To assess the reliability of Coast Guard SAR data, we interviewed knowledgeable officials, reviewed documentation, and electronically tested the data for obvious errors and anomalies. We interviewed Coast Guard officials to discuss the reliability issues we identified, such as the inability to attribute multi-boat SAR case responses to individual stations, as well as inconsistent data related to the types of boats used to conduct SAR cases. Regarding attributing multi-boat responses to individual stations, Coast Guard officials told us that some cases involve multiple boats and that the outcome of a SAR case may not be attributable to an individual station. Regarding boat assets used to conduct SAR cases, in February 2017, officials informed us that in 2015 the Coast Guard implemented changes to its Marine Information for Safety and Law Enforcement (MISLE) system and added around 500 controls, such as built-in data entry checks, to prevent potential data entry errors. Officials told us that this change could have caused some inconsistences in how the data is captured, but that the implementation of the changes includes testing and ongoing actions to resolve the issues. We determined that the data were sufficiently reliable for the purposes of this report to demonstrate selected station caseloads in our report. We compared Coast Guard actions to evaluate stations against criteria established in GAO’s Designing Evaluations guidance, which call for adhering to established evaluation design practices in order to achieve reliable results, the Coast Guard’s SAR response standard, and statutory requirements to conduct public outreach. To identify the extent to which the Coast Guard has a sound process to analyze the need for its air stations and air facilities, we reviewed laws, policies, and procedures related to its SAR mission. We reviewed Coast Guard documentation of processes it used to analyze the need for selected air facilities in 2014. We obtained and analyzed Coast Guard assumptions and station locations for determining overlapping SAR coverage in 2014 and used a mapping program to visually depict overlapping coverage provided by aviation assets, based on Coast Guard data, assumptions, and documentation. Additionally, we interviewed Coast Guard officials to obtain information on the extent to which the Coast Guard used findings and recommendations from selected studies, strategies, and plans in its analyses of the need for and locations of its air stations. We compared Coast Guard actions to evaluate air stations and air facilities against criteria established in GAO’s Designing Evaluations guidance which calls for adhering to established evaluation design practices in order to achieve reliable results, to determine if the Coast Guard’s methodological steps were sound. To determine the extent to which the Coast Guard has taken actions to implement the results of its analyses of its need for boat and air stations, we analyzed Coast Guard documents and reports to identify proposals put forth by the Coast Guard for permanently or seasonally closing stations it has identified as overlapping and unnecessary. We analyzed these proposed actions to determine whether proposed plans or decisions regarding stations aligned with the results of the Coast Guard analyses. Specifically, we reviewed the study reports, memoranda detailing district input on the results of the 2013 contractor study and their verification of the stations the study identified as unnecessarily duplicative, and compared the recommended closures from the various studies to determine if the outcomes were consistent. We also compared Coast Guard actions against its response standards and statutory requirements to conduct public outreach. Finally, we reviewed documents and information on these proposals and compared them against criteria in Standards for Internal Control in the Federal Government, and leading practices identified in the Project Management Institute’s Standard for Program Management. We conducted this performance audit from July 2016 through October 2017 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives. The U.S. Coast Guard (Coast Guard) uses several different types of assets to carry out its missions, including search and rescue. Coast Guard assets include boats, rotary wing aircraft (helicopters), fixed wing aircraft (planes), and cutters (including patrol boats and ships). The Coast Guard’s primary boat station search and rescue (SAR) assets are its boats, which it uses to conduct searches near shore and on inland waterways, such as harbors and bays that are too shallow for its larger cutters to access. Different boats have different capabilities (see table 3). For example, 47-foot motor life boats are slower than other boats, but can operate in heavy weather and up to 50 nautical miles offshore. The Coast Guard operates two types of aircraft: rotary wing (helicopters) and fixed wing (airplanes). Rotary wing aircraft operate from air stations, air facilities, cutters equipped with flight decks, and other locations that can support flight operations. The Coast Guard uses its rotary wing aircraft for search and rescue in coastal waters, among other mission uses. Rotary wing aircraft can hover and are equipped with hoists, which can allow rescue of distressed individuals from the water. Fixed wing aircraft operate from Coast Guard air stations, air facilities, and airports, and are used to conduct over-water searches and other missions. Coast Guard cutters are ships 65 foot or longer. They operate under the control of District or Area commands. According to the Coast Guard, cutters are suitable for conducting extended search and rescue operations because of their high endurance, communications systems, and ability to operate in heavier weather than other assets. Cutters carry boats that can directly rescue mariners in distress. Cutters with flight decks can serve as launch platforms for helicopters, which can help with SAR operations. The Coast Guard generally allocates boats to stations based on the needs and conditions of those stations. The Coast Guard also has other types of boats in its inventory that are used for a variety of missions that may include SAR missions. Table 3 provides details of selected boats used for search and rescue. Figures 9 through 12 show the extent of search and rescue coverage by U.S. Coast Guard (Coast Guard) boat stations in the contiguous United States and selected Coast Guard districts reported in September 2013. The extent of coverage in 2017 was the same as the Coast Guard’s 2013 contractor study reported. Table 4 provides details of selected U.S. Coast Guard (Coast Guard) stations recommended for permanent or seasonal closure and the search and rescue (SAR) caseloads they reported for fiscal years 2010 through 2016, as well as estimated fiscal year 2015 annual operating costs. Our analysis of Coast Guard SAR single-boat response case data from fiscal years 2010 through 2016 found that the 18 stations recommended for closure reported an average of about 15 single-boat SAR responses annually, compared to an annual average of about 41 single-boat responses for all boat stations. These numbers are based on station reported data in the Coast Guard’s Marine Information for Safety and Law Enforcement (MISLE) case management system, and only include cases in which a single boat was launched to conduct a SAR mission. Some SAR missions result in multiple stations launching due to factors such as close proximity of stations, case complexity such as weather conditions, or other factors such as boat availability or training. Including multilaunch cases could result in double counting of SAR cases and therefore these cases were excluded from our analysis. Due to flexibility in how Coast Guard stations report SAR responses, some seasonal stations, which are detached subunits of larger parent stations, report the number of cases to which they respond in combination with the parent station. Because we could not disaggregate this information, we do not report on individual cases from these stations. Table 5 provides details of selected stations recommended for permanent or seasonal closure and the SAR caseloads they reported during the winter months, for fiscal years 2010 through 2016. In addition to the contact above, Dawn Hoff (Assistant Director), Andrew Curry (Analyst-in-Charge), Chuck Bausell, Dorian Dunbar, Michele Fejfar, Peter Haderlein, Eric Hauswirth, Tracey King, John Mingus, Claire Peachey, and Christine San all made key contributions to this report.

Summary: The Coast Guard, within the Department of Homeland Security (DHS), is charged with preventing loss of life, injury, and property damage in the maritime environment through its SAR mission. It maintains over 200 stations with various assets, such as boats and helicopters (depending on the station), along U.S. coasts and inland waterways to carry out this mission, as well as its other missions such as maritime security. Resource limitations and changes to operations require the Coast Guard to periodically reexamine the need for these stations. GAO was asked to review these efforts. This report addresses, among other objectives, the extent to which the Coast Guard has (1) a sound process for analyzing the need for its boat stations and (2) taken actions to implement its boat station process results. GAO reviewed Coast Guard laws, standards, and guidance; analyzed Coast Guard data on station locations and SAR coverage; and analyzed the process and criteria used to evaluate its station needs and compared it with established evaluation design practices and internal control standards. GAO also interviewed Coast Guard officials. GAO found that the U.S. Coast Guard has a sound process for analyzing its boat stations that includes clear and specific steps for analyzing the need for stations using terms that can be readily defined and measured. In 2013, following this process, the Coast Guard and its contractor identified 18 unnecessarily duplicative boat stations with overlapping coverage that could be permanently closed without negatively affecting the Coast Guard's ability to meet its 2-hour search and rescue (SAR) response standard and other mission requirements. The process was designed to ensure the Coast Guard met or exceeded requirements to maintain SAR coverage and to account for such factors as boat downtime and surge capacity to respond to certain incidents. Further, the boat station analysis did not consider potential SAR responses by the Coast Guard's air stations and facilities, which can provide additional overlapping coverage. Coast Guard officials said that the closures would, among other things, help improve operations by consolidating boat station caseloads to help ensure personnel were active enough to maintain training requirements. In 2017, the Coast Guard affirmed that its leadership believes the 2013 study remains valid, but so far the agency has not taken actions to implement the closures identified by its sound process. Instead, the Coast Guard is recommending conversion of some year-round stations to seasonal stations that would operate during the summer. Coast Guard officials stated that seasonal closures are preferable to no action, given its limited resources, the significant overlapping SAR coverage, and potential to improve operations. However, permanently closing unnecessarily duplicative stations may better position the Coast Guard to improve its operations. It could also achieve up to $290 million in cost savings over 20 years, if stations were permanently closed. GAO is making three recommendations, including one recommendation that the Coast Guard close unnecessarily duplicative stations that its analysis identified. DHS concurred with the recommendations and stated it plans to act to eliminate unnecessary duplication.
