FINDINGS FOR THE AMERICAN SAMOA COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the Territory of American Samoa pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the American Samoa Coastal Nonpoint Pollution Control Program, July 1995. The National Oceanic and Atmospheric Administration (NOAA) and the U.S. Environmental Protection Agency (EPA) reviewed this information and evaluated the extent to which it conforms with the requirements of CZARA. NOAA and EPA commend American Samoa on the substantial amount of time and effort put into developing your program and we appreciate the commitment you have shown to complete an ambitious task with limited resources. We will continue to work with coastal states and territories to ensure that these findings represent an accurate assessment of current state and territory abilities and efforts to address coastal nonpoint source pollution. We recognize that there may be further administrative changes to the coastal nonpoint program that will impact these findings and we assure you that, once such changes are finalized, we will review these findings in light of the changes and make any necessary adjustments. APPROVAL DECISION NOAA and EPA approve the coastal nonpoint pollution control program submitted by the Territory of American Samoa pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990, subject to certain conditions. This document provides the specific findings used by NOAA and EPA as the basis for the decision to approve American Samoa's program. It also provides the rationale for the findings and includes conditions that will need to be met for American Samoa to receive final approval of its program. The timeframes associated with conditions become effective on the date of the approval letter for these findings. INTRODUCTION This document is organized by the major nonpoint source categories and subcategories identified in the section 6217(g) guidance and the administrative elements identified in the program guidance (including the boundary for the 6217 management area). Where appropriate, NOAA and EPA have grouped categories and subcategories of management measures into a single finding. The structure of each finding follows a standard format. Generally, the finding is that the Territory's program includes or does not include management measures in conformity with the (g) guidance and includes or does not include enforceable policies and mechanisms to ensure implementation. In some cases, the finding reflects that the Territory has identified a back-up enforceable policy, but has not yet demonstrated the ability of the authority to ensure implementation. For further understanding of terms in this document, the reader is referred to the following: Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters (EPA, January 1993) Coastal Nonpoint Pollution Control Program: Program Development and Approval Guidance (NOAA and EPA, January 1993) Flexibility for State Coastal Nonpoint Programs (NOAA and EPA, March 1995) The references in this document refer to the American Samoa Coastal Nonpoint Pollution Control Program, July 1995 ("program submittal"). NOAA and EPA have written this document as succinctly as possible. We have relied upon, but do not repeat here, the extensive information that the Territory has included in its program submittal.

BOUNDARY FINDING: American Samoa has included the entire Territory as the management area within which it will implement the 6217 coastal nonpoint program. Therefore, American Samoa's boundary is sufficient to control the land and water uses that have, or are reasonably expected to have, a significant impact on the coastal waters of American Samoa. II. AGRICULTURE FINDING: American Samoa's program includes management measures in conformity with the 6217(g) guidance for erosion and sediment control and for confined animal facilities, except that it does not provide for appropriate waste utilization systems for animal waste. American Samoa's program does not include management measures in conformity with the 6217(g) guidance for pesticide management. The Territory has identified a back-up authority for the erosion and sediment control and confined animal facilities measures, but has not yet demonstrated the ability of the authority to ensure implementation of the management measures throughout the 6217 management area. The program does not include enforceable policies and mechanisms to ensure implementation of the pesticide management measure throughout the 6217 management area. American Samoa has provided sufficient justification to support an exclusion of the grazing and irrigation water management measures, but not for exclusion of the nutrient management measure as it applies to animal waste. CONDITION: Within one year, American Samoa will (1) include in its program management measures in conformity with the 6217(g) guidance for confined animal facilities, nutrient management as it applies to animal waste, and pesticides; (2) include in its program enforceable policies and mechanisms to implement the pesticide management measure; and (3) provide a strategy (in accordance with section XIII, page 12) for use of the American Samoa Environmental Quality Act (EQA) as a back-up enforceable policy and mechanism to ensure implementation of the management measures for erosion and sediment control, confined animal facilities, and nutrient management as it applies to animal waste. RATIONALE: American Samoa expresses its commitment to implement the management measures for erosion and sediment control and confined animal facilities, lists some of the practices that it currently uses to implement the measures, and sets forth a process and schedule that will guide the Territory's implementation activities. However, the Territory does not address waste utilization systems for animal waste management, and needs to add this component to its confined animal facility program to assure that animal waste is not over-applied to land and, thereby, reaches coastal waters through leaching or runoff. The EQA, codified as ASCA, Title 24, Chapter 01, and the American Samoa Water Quality Standards (ASWQS), codified as ASAC, Title 24, Chapter 02, provide the Environmental Quality Commission (EQC) with the authority to require best management practices to prevent soil erosion and prohibit other water pollution resulting from agricultural practices (see ASCA 24.0107 and ASAC 24.0205 and 24.0207(a) (10)). The American Samoa Environmental Protection Agency (ASEPA) is currently revising the ASWQS and developing erosion and sediment control regulations and guidance documents on agricultural practices. These documents, to be adopted by the Natural Resources Conservation Service (NRCS), the American Samoa Community College (ASCC), and the American Samoa Coastal Management Program (ASCMP) and implemented under the authority of the EQA, could include the management measures for erosion control and confined animal facilities. Crop agriculture in American Samoa is largely of a subsistence nature, and confined animal facilities in the Territory similarly consist of a relatively large number of family-operated piggeries, which, although individually small in size, can have a significant cumulative effect on water quality. The Territory proposes to implement these measures through a program based on voluntary implementation, technical assistance, and outreach from the NRCS, the American Samoa Department of Agriculture (DOA), the ASCC, and the American Samoa Soil and Water Conservation District (ASSWCD). In addition, an assessment of management practices will be conducted to determine those most suitable for the Territory's steep terrain and intense rainfall. The Territory needs to demonstrate that its identified enforceable policies and mechanisms can ensure implementation if voluntary efforts fail to achieve compliance with the management measures. In reviewing the American Samoa program submittal, NOAA and EPA note that, pursuant to ASAC 24.0209, the EQC has the authority to review and permit all point and nonpoint sources of pollution within the Territory. ASEPA and ASCMP program coordinators, however, have indicated to NOAA and EPA that the Territory plans to use the voluntary approach described above, coupled with existing backup authority under ASAC 24.0205 and 24.0207, rather than the permitting authority. The DOA has the authority, under 24.1205 of the American Samoa Pesticide Act, ASCA, Title 24, Chapter 12, to adopt rules regarding the application of pesticides. DOA has delegated this authority to the executive secretary of the EQC, which has promulgated rules at ASAC, Title 24, Chapter 06. The Pesticide Act, however, pertains exclusively to the use of regulated pesticides and does not include the use of techniques such as integrated pest management. American Samoa has requested an exclusion from the nutrient management measure, based on relatively low rates of application of commercial fertilizer. The nutrient management measure, however, addresses land application of manure as well as of commercial fertilizer. Because the many small confined animal facilities in the Territory have the potential to generate animal waste as a pollutant to surface and groundwater, the Territory needs to implement the nutrient management measure as it applies to animal waste from these sources. There are no domestic livestock that utilize range, pasture, or grazing lands in American Samoa, and, because of the 125 to 200 inch per year rainfall in the Territory, the use of irrigation is not needed. Therefore, the Territory has demonstrated that grazing and irrigation are not, and not anticipated to be, significant contributors of pollutants to American Samoa's coastal waters, and should be excluded from the program. II. FORESTRY FINDING: American Samoa has provided sufficient justification to support a categorical exclusion of forestry from its coastal nonpoint program. RATIONALE: Forestry is not practiced commercially in American Samoa, and although some wood is harvested for fuel and handicrafts, such activity is minimal and at the subsistence level. Therefore, forestry activities do not and are not reasonably anticipated to present significant adverse impacts to coastal waters. IV. URBAN A. NEW DEVELOPMENT, SITE DEVELOPMENT, CONSTRUCTION SITE EROSION AND SEDIMENT CONTROL and CONSTRUCTION SITE CHEMICAL CONTROL FINDING: American Samoa's program does not include management measures in conformity with the 6217(g) guidance but does include enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within one year, American Samoa will include in its program management measures in conformity with the 6217(g) guidance for new development, site development, and construction site erosion and sediment and chemical control. RATIONALE: The American Samoa Coastal Management Program implements the Territorial land use permit (LUP) program, under which permits are required for all activities that may cause or threaten to cause adverse impacts to coastal resources, except where specifically exempted by law. ASCMP permits must be consistent with the ASCMP implementing regulations, ASAC Title 26, Chapter 02, and are reviewed through an interagency process know as the Project Notification and Review System (PNRS). The Development Planning Office (DPO) and other PNRS member agencies can condition permits for compliance with their authorizing legislation. Both DPO and ASEPA have the authority to issue permit conditions related to erosion control under the American Samoa Coastal Management Act (ASCMA) and the EQA, respectively. These acts and their implementing rules do not, however, completely implement the management measures. For instance, they do not require the post-development loadings of total suspended solids or peak runoff rates specified in the management measure for new development, nor do they fully implement the requirements for protection of natural drainage features and vegetation in the site development management measure. The ASEPA is currently revising its erosion control regulations for implementation under the EQA through the PNRS. The ASEPA nonpoint source coordinator indicated in a personal communication that ASEPA intends to incorporate all of these measures into the revised regulations. The Territory is also currently undertaking studies to determine the management practices most feasible for the climate and geography of American Samoa. NOAA and EPA recognize the unique characteristics of American Samoa and anticipate that completion of these activities will provide for full implementation of the new development, site development, and construction site erosion and sediment and chemical control management measures. The Territory has cited its pesticide and storage tank regulations as implementing authorities for the construction site chemical control management measure; however, these authorities do not address nonregulated pesticides, nutrients, and other toxic substances, such as oil, grease, and gasoline, generated on construction sites. The Territory needs to develop management measures for such chemicals and clearly demonstrate that permits, including appropriate conditions, can be used to implement the management measure. B. WATERSHED PROTECTION and EXISTING DEVELOPMENT FINDING: American Samoa's program does not include management measures in conformity with the 6217(g) guidance for watershed protection and existing development but does include enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within three years, American Samoa will include in its program management measures in conformity with 6217(g) guidance for watershed protection and existing development. RATIONALE: Several agencies in American Samoa, including ASEPA, DPO, and the Department of Marine and Wildlife Resources (DMWR), have authorities and carry out activities related to watershed protection. For example, ASEPA has begun watershed assessment, planning, and remediation in the Malaeimi Valley and Lauli'i Village and will begin similar efforts in the Pala Lagoon area. The ASCMA contains provisions to protect unique areas and resources from destruction and inappropriate development and directs DPO to develop strategies to cope with cumulative impacts on land and water resources. These activities, however, are not coordinated in a meaningful fashion at present. In its program submittal, the Territory describes a schedule of activities that it will undertake to implement the watershed protection measure, including development of a memorandum of understanding among ASEPA, DPO, and DMWR, a resource inventory and information analysis, and development and implementation of a watershed protection plan. When implemented, these efforts should provide an effective means of watershed protection. For the existing development management measure, the Territory proposes to assess opportunities to reduce pollutant loadings. Implementation will be dependent both on type of solution proposed and on cost. NOAA and EPA suggest that the Territory integrate the existing development measures into the watershed planning process discussed above. C. NEW and OPERATING ON-SITE DISPOSAL SYSTEMS (OSDS) FINDING: American Samoa's program includes management measures in conformity with the 6217(g) guidance and enforceable policies and mechanisms to ensure implementation throughout the 6217 management area, except that it lacks (1) provisions for protective setbacks from surface waters and wetlands and to direct placement of on-site disposal systems (OSDS) away from unsuitable areas; (2) a program for inspection of new and operating OSDS; and (3) a program to require denitrifying systems where nitrogen-limited surface waters may be adversely affected by nitrogen loadings from OSDS. CONDITION: Within two years, American Samoa will finalize its proposed OSDS regulations, and include management measures in conformity with the 6217(g) guidance on setbacks and avoidance of unsuitable areas; inspection of new and operating systems; and requirements for denitrifying systems where nitrogen-limited surface waters may be adversely affected by nitrogen loadings from OSDS. RATIONALE: Regulation of OSDS is currently fragmented among several Territorial agencies. An LUP must be obtained from the PNRS for any new construction or renovation. OSDS permit conditions are included in this permit for any structure requiring an OSDS. The American Samoa Power Authority (ASPA), a PNRS member agency, requires hook up to the sewer system or proper septic tank installation and conducts a final inspection prior to connecting water or power lines to new or modified structures. The building inspections branch of the Department of Public Works (DPW), however, is responsible for inspecting OSDS systems during installation. ASEPA and ASPA currently are implementing an OSDS project, which involves training, development of new regulations, and public education. The existing and proposed Territorial regulations do not contain adequate provisions for inspection during installation of new systems, and for operation, maintenance, and inspection of existing systems. The ASEPA regulations also need to address the need for denitrifying systems where nitrogen-limited surface waters may be adversely affected by nitrogen loadings from OSDS and other aspects of the 6217(g) guidance as noted in the Finding above. D. POLLUTION PREVENTION FINDING: American Samoa's program includes management measures in conformity with the 6217(g) guidance. RATIONALE: In its program submittal, American Samoa describes a number of programs and activities that address the components of this management measure. These programs and activities include a household hazardous waste education and collection program, the establishment of used oil collection centers, an anti-litter campaign, stream and beach clean ups, and an industrial and government facility pollution prevention program. E. ROADS, HIGHWAYS, AND BRIDGES FINDING: American Samoa's program includes management measures in conformity with the 6217(g) guidance for planning, siting, and developing roads and highways and bridges and includes enforceable policies and mechanisms to ensure implementation of the planning, siting, and development measure, the measure for bridges, and the construction project erosion and sediment control and chemical control measures. The program does not include management measures in conformity with the 6217(g) guidance for construction project erosion and sediment control, construction site chemical control, operation and maintenance, and runoff systems and does not include enforceable policies and mechanisms to ensure implementation of the operation and maintenance and runoff measures throughout the 6217 management area. CONDITION: Within three years, American Samoa will include in its program management measures in conformity with the 6217 (g) guidance for construction project erosion and sediment control, construction site chemical control, operation and maintenance, and runoff systems. Within three years, the Territory will also include in its program enforceable policies and mechanisms to ensure implementation of the operation and maintenance and runoff measures throughout the 6217 management area. RATIONALE: The PNRS permitting process and ASCMP administrative rules include provisions to implement the planning, siting, and development and bridges management measures. Existing rules for the ASCMA and EQA do not contain specific elements to ensure implementation of the construction project erosion and sediment control and construction site chemical control measures, but the ASEPA erosion and sediment control regulations currently being revised have the potential to implement these measures. The Territory's program submittal identifies the EQA as an enforceable authority for the operation and maintenance and runoff measures, but the Territory needs to provide further description and detail on how it intends to use this authority to ensure that the DPW, which constructs all public roads in American Samoa, complies with the measures. If the Territory decides to use the EQA as a back-up authority, it will need to develop a strategy in accordance with section XIII, page 12. V. MARINAS AND RECREATIONAL BOATING A. MARINA FLUSHING, WATER QUALITY ASSESSMENT, HABITAT ASSESSMENT, SHORELINE STABILIZATION, FUELING STATION DESIGN, AND SEWAGE FACILITY MANAGEMENT FINDING: American Samoa's program does not include management measures in conformity with the 6217(g) guidance but does include enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within three years, American Samoa will include in its program management measures in conformity with the 6217(g) guidance for marina flushing, water quality assessment, habitat assessment, shoreline stabilization, fueling station design, and sewage facility management. RATIONALE: Authority to regulate new and expanding marinas in American Samoa exists under the ASCMP land use permitting program, but existing regulations and guidance do not fully implement the management measures. The Territory has proposed to develop a marina guidance document, based upon the 6217(g) guidance, which would address marina siting and design. Implementation of the guidance document would be ensured through LUP conditions. B. STORMWATER MANAGEMENT, SOLID WASTE MANAGEMENT, FISH WASTE MANAGEMENT, LIQUID MATERIAL MANAGEMENT, PETROLEUM CONTROL, BOAT CLEANING, PUBLIC EDUCATION, SEWAGE FACILITY MAINTENANCE, and BOAT OPERATION FINDING: American Samoa's program does not include management measures in conformity with the 6217(g) guidance. The Territory has identified a back-up enforceable policy and mechanism for these measures, but it has not yet demonstrated the ability of this authority to ensure implementation of the management measures throughout the 6217 management area. CONDITION: Within three years, American Samoa will include in its program management measures in conformity with the 6217(g) guidance and develop a strategy (in accordance with section XIII, page 12) for use of the EQA as a back-up enforceable policy and mechanism to ensure implementation of these management measures throughout the 6217 management area. RATIONALE: American Samoa proposes to implement these measures on a voluntary basis, primarily through the use of a marina guidance document, using provisions of the EQA as a back-up authority (see especially ASCA 24.0107 and ASAC 24.0207). The Territory does not at present, however, have regulations or guidance to provide a means of implementing the voluntary program. In addition, the Territory needs to develop a strategy for use of the EQA as a back-up authority. VI. HYDROMODIFICATION FINDINGS: American Samoa's program does not include management measures in conformity with the 6217(g) guidance but does include enforceable policies and mechanisms to ensure implementation throughout the 6217 management area for the channelization and channel modification and eroding streambank and shoreline management measures, except that the program does not include (1) a process to improve surface water quality and restore in-stream and riparian habitat through the operation and maintenance of existing modified channels and (2) a process to identify and develop strategies to solve existing nonpoint source pollution problems caused by eroding streambanks and shorelines that do not come up for review under existing permit authorities. American Samoa has provided sufficient justification to support an exclusion of the dams management measures from the coastal nonpoint program. CONDITION: Within three years, American Samoa will include in its program (1) management measures in conformity with the 6217(g) guidance for channelization and channel modification, and eroding streambanks and shorelines; (2) a process to improve the physical and chemical characteristics of surface waters and restore instream and riparian habitat in existing modified channels; and (3) a process to stabilize eroding streambanks and shorelines causing nonpoint problems that are not reviewed under existing authorities. RATIONALE: LUPs issued through the PNRS under the authority of the ASCMA and EQA are required for new channelization activities. While permit applications are reviewed for impacts on water quality and habitat, existing regulations do not completely implement the measures. The Territory may choose to consider revisions to the water quality standards, erosion and sediment control regulations, or ASCMP regulations as a mechanism to achieve full implementation of the measures. For existing channels, the program submittal identifies the need for an assessment of existing channels and prioritization of areas to be restored; however, authorities to ensure implementation of the measure are not identified, nor are management measures adopted in the form of regulations or guidance manuals. To implement the management measure for eroding streambanks and shorelines that are causing nonpoint problems, American Samoa plans to assess and prioritize shoreline and streambank needs for stabilization and then begin a stabilization program. This proposal, however, does not include management measures and clear processes to ensure implementation of the measure throughout the 6217 management area. Since the program submittal points out that there are no dams in American Samoa meeting the definition in the (g) guidance, and that none are expected to be constructed in the future, the management measures for dams are excluded from the program. VII. WETLANDS, RIPARIAN AREAS, AND VEGETATED TREATMENT SYSTEMS FINDINGS: American Samoa's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation of the management measures. RATIONALE: Land use permits are required from the PNRS for dredging or filling activities in wetlands. The ASCMA regulations include provisions that implement the management measures. Proposals for new work in or near wetlands and streams are reviewed for their impacts on water quality and habitat. The ASCMP also has an aggressive wetland restoration program underway. Pretreatment practices for runoff from upland areas are being introduced as part of the implementation of the urban management measures. VIII. ADMINISTRATIVE COORDINATION FINDING: American Samoa's program includes mechanisms to improve coordination among Territorial agencies and between Territorial and local officials in implementing the coastal nonpoint program. RATIONALE: The program submittal describes existing mechanisms to coordinate Territorial efforts to address nonpoint pollution of coastal waters. Existing mechanisms include the EQC, PNRS, and the ASSWCD. The ASEPA will act as the lead agency on all nonpoint pollution program coordination, working closely with the ASCMP. The program submittal also describes new coordination mechanisms the Territory intends to create. A coordination committee will be convened under ASEPA leadership to develop and implement management measures not currently in place. Memoranda of understanding will be entered into with agencies implementing applicable management measures. Special attention should be given to coordinating the implementation of the OSDS management measures by the Territorial agencies with responsibility in this area. IX. PUBLIC PARTICIPATION FINDING: American Samoa's program provides opportunities for public participation in the development and implementation of the coastal nonpoint program. RATIONALE: The Territory's program submittal describes activities that provide ongoing opportunities for public participation in the coastal nonpoint program. These include workshops on nonpoint source pollution and on the section 319 and 6217 programs for government, the private sector, and the general public; public comments on the draft Coastal Nonpoint Pollution Control Program document; and public education on management measures and practices as they are implemented. A number of workshops and demonstration projects have already occurred. X. TECHNICAL ASSISTANCE FINDING: American Samoa's program includes technical assistance to village governments and the general public for implementing the nonpoint program. RATIONALE: The section 319 program in American Samoa includes several projects in which financial and technical assistance are provided to demonstrate nonpoint source best management practices. Other types of technical assistance will include brochures, training sessions, and other hands-on assistance. XI. CRITICAL COASTAL AREAS and ADDITIONAL MANAGEMENT MEASURES FINDING: American Samoa's program identifies and includes a continuing process for identification of critical coastal areas and provides for the development and continuing revision of management measures applicable to critical coastal areas and cases where the 6217(g) measures are fully implemented but water quality threats or impairments persist. RATIONALE: In its program submittal, the Territory has identified currently designated special management areas under the ASCMP as critical coastal areas under its coastal nonpoint program. These areas are Pago Pago Harbor, Pala Lagoon, and Leone Pala. The beneficial uses of these water bodies are either not being met or are threatened. Land uses and other activities prohibited by the ASWQS are also present. The program identifies additional management measures for small piggeries, shoreline land filling, and solid waste management as preliminary needs. The program includes a process for continually developing and revising these and other measures for application in critical coastal areas and other relevant areas. XII. MONITORING FINDING: American Samoa's program does not include a plan to assess over time the success of the management measures in reducing pollution loads and improving water quality. CONDITION: Within one year, American Samoa will include in its program a monitoring plan that enables the Territory to assess over time the extent to which implementation of management measures is reducing pollution loads and improving water quality. RATIONALE: American Samoa outlines its monitoring program, stating that it will consist of routine water quality testing, on-site inspections of management practices, self-reporting by land owners or permittees, a tracking system for BMPs, an annual report, and possibly a volunteer monitoring program. While these activities address the major elements of a successful monitoring program, the Territory has not clearly specified what it will do to assess over time whether the management measures are reducing pollution loads and improving water quality. For example, there is no discussion of the specific monitoring and analyses that will be performed to demonstrate and associate water quality trends with management measure implementation at the major bays of Tutuila Island (p. 138). The sedimentation study described on page 138 provides an opportunity to establish a baseline for relating water quality to management measure implementation, but the Territory plans to complete the study in fiscal year 1996 rather than continue or expand the effort over time as management measures are implemented. Thus, none of the current or planned monitoring efforts are described in adequate detail to determine if they might be useful to evaluate the effectiveness of the Territory's coastal nonpoint program. American Samoa needs to continue development of its proposed monitoring program. The Territory should include in its plan information regarding the number and location of monitoring stations, the types and frequency of water quality data being collected, and the analytic approaches that will be employed in conjunction with existing monitoring efforts to assess the success of management measures in achieving water quality objectives. The Territory should include some inexpensive tracking of management measure implementation in conjunction with water quality monitoring, as such information is needed to assess the success of management measures in achieving water quality objectives. NOAA and EPA are willing to assist the Territory in these efforts. XIII. STRATEGY AND EVALUATION OF BACKUP AUTHORITIES Within one year, American Samoa will develop a strategy to implement the management measures for agricultural erosion and sediment control, confined animal facilities, nutrient management as it applies to animal waste, marina and boat operation and maintenance, and marina stormwater management throughout the 6217 management area. This strategy will include a description and schedule for the specific steps the Territory will take to ensure implementation of the management measures; describe how existing or new authorities can be used to ensure implementation where voluntary efforts are unsuccessful; and identify measurable results which, if achieved, will demonstrate the Territory's ability to achieve implementation of the management measures using the described approach. In order to evaluate the adequacy of this strategy, American Samoa will also develop and apply credible survey tools to demonstrate the ability of the Territory's approach to achieve implementation for these management measures. The use of credible assessment techniques is necessary in order for NOAA and EPA to evaluate, at the end of the three year period described in the March 16, 1995 guidance issued by NOAA and EPA entitled Flexibility for State Coastal Nonpoint Programs, whether the Territory's approach has been successful or whether new, more specific authorities will be needed.
