FINDINGS FOR THE NORTH CAROLINA COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the State of North Carolina pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the North Carolina Coastal Nonpoint Pollution Control Program, July 1995 and supplemental material provided by North Carolina subsequent to the program submittal. 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 North Carolina 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 State of North Carolina 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 North Carolina's program. It also provides the rationale for the findings and includes conditions that will need to be met for North Carolina 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 state 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 state has identified a back-up enforceable policy, but has not 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 North Carolina 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 State has included in its program submittal. Further information and analysis, including material provided by North Carolina subsequent to the program submittal, is contained in the administrative record for this approval decision and may be reviewed by interested parties at the following locations: EPA/Office of Wetlands, Oceans and Watersheds Assessment and Watershed Protection Division Nonpoint Source Control Branch 401 M St., SW (4503-F) Washington, DC 20460 Contact: Dov Weitman (202-260-7088) NOAA/Office of Ocean and Coastal Resource Management Coastal Programs Division SSMC-4, N/ORM3 1305 East-West Highway Silver Spring, MD 20910 Contact: Joelle Gore (301/713-3117, x177) U.S. EPA, Region 4 61 Forsyth Street, SW Atlanta, GA 30303 CONTACT: Robert B. Howard (404-562-9370) I. BOUNDARY FINDING: North Carolina's proposed 6217 management area excludes existing land and water uses that have or are reasonably expected to have a significant impact on the coastal waters of the State. CONDITION: Within one year, the North Carolina Department of Environment, Health, and Natural Resources, U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, and other relevant State, local, and Federal agencies will participate in a cooperative process to review relevant information and to determine an appropriate 6217 management area boundary to protect the State's coastal waters from nonpoint source pollution. North Carolina's program will include management measures in conformity with the 6217(g) guidance, and enforceable policies and mechanisms that ensure implementation of the management measures throughout an expanded 6217 management area. RATIONALE: North Carolina's proposed 6217 management area is the State's existing coastal zone boundary, which encompasses the twenty coastal counties and is regulated under the State's Coastal Area Management Act (CAMA). Based on an examination of information provided by the State in its program submittal, including data from the State's Clean Water Act Section 305(b) reports, the State's 1989 Nonpoint Source Assessment Report, and basinwide water quality plans developed for the Neuse, Lumbar, Tar-Pamlico, and Cape Fear River Basins, NOAA and EPA believe that there are land and water uses outside of the State's existing coastal zone boundary that have or are reasonably expected to have a significant impact on the State's coastal waters. For example, in Table 5.7 in Volume I of the program submittal, use support ratings are listed for Neuse River sub-basins within the federally recommended management area. Sub-basin 03-04-11, which is located outside of the State's CAMA boundary, lists 152 miles of streams and rivers with a water quality rating of only "partially supporting." The same sub-basin lists agriculture as the contributor of water quality impairment for 84 miles of those 152 miles rated as partially supporting. Similar information suggesting water quality impairments from nonpoint pollution was presented for other sub-basins including the Lumbar, Tar-Pamlico, and Cape Fear watersheds. The Program Development and Approval Guidance (1993) describes two options that States have in delineating their 6217 management areas. First, the State can modify its existing coastal zone boundary to incorporate the entire 6217 management area. Second, if the State chooses not to modify its existing coastal zone boundary, the State can rely on other programs, including enforceable policies and mechanisms, to control land and water uses and ensure the implementation of the 6217 (g) management measures throughout the 6217 management area. In two cases (marinas and hydromodification), the State will need to expand its current programs and enforceable authorities beyond their current jurisdiction or identify other enforceable policies and mechanisms to ensure implementation of the management measures in an expanded boundary area. II. AGRICULTURE FINDING: North Carolina's program includes management measures in conformity with the 6217(g) guidance, except the program does not include management measures for pesticide management, irrigation water management, and does not include the limiting nutrient concept as part of the nutrient management measure. North Carolina has enforceable policies and mechanisms to ensure implementation for some confined animal facilities, but cannot ensure implementation for all facilities as described in the 6217 (g) guidance. North Carolina has identified a backup enforceable policy and mechanism to implement the erosion and sediment control management measure which also may be used for other agricultural management measures, but has not demonstrated the authority's ability to ensure implementation throughout the 6217 management area. CONDITIONS: Within two years, North Carolina will include in its program management measures in conformity with the agricultural management measures for nutrient management, pesticide management, and irrigation water management. Within one year, North Carolina will develop a strategy (in accordance with section XIV, page 14) to implement the agricultural management measures throughout the 6217 management area. RATIONALE: North Carolina has a detailed regulatory program under its Nondischarge Rule for animal waste management systems and nutrient management for land application of those wastes (NCAC T15A:02H .0122 et seq.). The State's program excludes facilities smaller than 100 head of cattle, 250 swine or 30,000 birds with a liquid waste system. This could potentially exclude from the State's program approximately 85,000 animal units in the State's existing coastal zone that are held in facilities large enough to be subject to the 6217(g) management measures for animal facilities. The State's Agriculture Cost-Share Program (ASCP), which operates Statewide, includes practices that are in conformity with the animal waste facility management measures and provides a voluntary mechanism for implementing the measures below the thresholds of the Nondischarge Rule. The State has also passed new requirements for animal waste management which provides a tiered permitting program for animal waste management systems. The program supplants the "deemed permitted" approach established in the original 1992 regulations, and requires permits to be issued by the Department of Water Quality on a phased-in priority basis for construction and operation of animal waste management systems. Priority for issuance of permits will be given to the largest operations (NCAC T15A: 02H .0217). In 1996, the State General Assembly also enacted a new Clean Water Management Trust Fund which will provide substantial funds on an annual basis for a broad range of water quality-related activities. With respect to other aspects of North Carolina's agricultural program, the State has many efforts underway that can be used to address problems stemming from agriculture, including basin-wide programs and various education and research programs by the Cooperative Extension Service and Agricultural Research Service. Additionally, the State is exploring the potential of using a cross- compliance mechanism to encourage pollution prevention through Use Value Taxation. The State has identified a wide range of best management practices that it can use to achieve the management measures; however, the State has not clearly described how it will select and apply practices that, in combination, will achieve the measures. Moreover, several key elements of the management measures are not addressed by those practices identified in the State's program submittal, including integrated pest management, irrigation scheduling, water-measuring devices, and measurement of crop water needs. The State's water quality standards (NCAC T15A: 02B .0200 et seq.) may serve as a backup enforceable policy and mechanism for the agricultural management measures, but the State has not demonstrated that the water quality standards will ensure implementation throughout the 6217 management area. Any source of water pollution which precludes any of the designated uses of the water body is considered to be violating a water quality standard. Under the statute, the State also has authority to require implementation of best management practices if the State's turbidity standard is violated; compliance with the turbidity standard is achieved when State-recommended best management practices are implemented. III. FORESTRY FINDING: North Carolina's program includes management measures in conformity with the 6217(g) guidance and enforceable policies and mechanisms to ensure implementation. RATIONALE: In order to remain exempt from the Sedimentation Pollution Control Act (113A-52(6)), forestry operators must adhere to the BMP requirements set forth by rule in the Forest Practices Guidelines Related to Water Quality (NCAC T15A: 1I.0101-.0209). These guidelines and supporting practices contained in the Forestry Best Management Practices Manual and Best Management Practices for Forestry in North Carolina Wetlands are in conformity with the management measures. Forestry operations are inspected for compliance with the Forest Practices Guidelines, and the State has included summary data for years 1990 through 1994 in its program submittal. While North Carolina has in place a sound forestry program, NOAA and EPA encourage the State to pursue its recommendations for improvement found on pages 5-1 through 5-4 of the Forestry section of the State's submittal. IV. URBAN A. NEW DEVELOPMENT, SITE DEVELOPMENT, and CONSTRUCTION SITE EROSION AND SEDIMENT CONTROL FINDING: North Carolina's program includes management measures in conformity with the 6217(g) guidance, except that the program does not include management measures to require an 80 percent total suspended solids (TSS) reduction for new development. The program includes enforceable policies and mechanisms to ensure implementation, except the program does not include enforceable policies and mechanisms for sites disturbing one acre or less for the new development and site development management measures. The State has identified a backup enforceable policy applicable to the erosion and sediment control management measure for sites disturbing one acre or less , but has not demonstrated the ability to ensure implement throughout the 6217 management area. CONDITION: Within two years, North Carolina will include in its program management measures in conformity with the 80 percent TSS standard for new development, and enforceable policies and mechanisms to ensure implementation of the new development and site development management measures on sites disturbing one acre or less. For the erosion and sediment control measure, the State will, within one year, develop a strategy (in accordance with Section XIV, page 14) to implement the measure throughout the 6217 management area. RATIONALE: North Carolina's erosion and sediment control rules require an approved erosion and sedimentation control plan for activities disturbing more than one acre of land. The plans require identification of critical areas, limitation of exposed areas, and measures to ensure that postdevelopment velocity of the ten year storm runoff does not exceed the predevelopment velocity. In addition, the rules require that during construction, sediment is retained on site, cut and fill activities are restricted, and buffer zones are established to protect waterbodies. Further, North Carolina's Erosion and Sediment Control Planning and Design Manual identifies conservation standards that conform to these management measures. The CAMA provides additional protection for coastal wetlands and estuarine waters through its permitting process. For sites disturbing one acre or less, the State proposes to use its turbidity standard as a back-up enforceable policy and mechanism. North Carolina's stormwater rules (NCAC T15A 02H .1000) require that development activities disturbing more than one acre in coastal counties control runoff. Developers have a number of options to control runoff, including wet detention ponds designed to achieve an 85 percent TSS removal and storage of runoff from a one-inch rainfall from the site above the permanent pool. However, the rules do not require that controls, either alone or in combination, other than wet detention ponds achieve the 80 percent TSS standard. In addition, both the erosion and sedimentation control and stormwater rules apply only to sites disturbing greater than one acre, and the stormwater rules apply only in the existing coastal management area, in designated water supply watersheds, and in areas with critical proximity to High Quality or Outstanding Resource Waters. B. WATERSHED PROTECTION and EXISTING DEVELOPMENT FINDING: North Carolina's program does not include management measures for watershed protection and existing development in conformity with the 6217 (g) guidance but includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within two years, the State will include in its program management measures in conformity with the watershed protection and existing development management measures. RATIONALE: North Carolina proposes to use a number of watershed-level water quality protection laws and regulations, the Basinwide Planning Initiative, and the erosion and sedimentation control rules discussed above to implement the watershed protection management measure. While these programs can implement certain aspects of the measure, such as avoiding conversion of areas susceptible to erosion, they do not provide for comprehensive watershed protection throughout the management area. Preserving areas that provide water quality benefits and siting of development to protect the natural integrity of waterbodies are not fully addressed by these programs. North Carolina's Areas of Environmental Concern (AECs) and Water Supply Watershed Rules may provide for protection of certain watershed features, but these programs are too narrowly defined to accomplish watershed protection throughout the 6217 management area. North Carolina has undertaken the Basinwide Planning Initiative to identify and restore full use to impaired waters, identify and protect highly valued resource waters, and manage problem pollutants within each basin through development of consistent and effective long-range management strategies that protect both the quality and intended uses of surface waters. The planning approach is a five year process that involves data collection, modeling, and the development of pollution control strategies. While the planning cycle is tied to issuance and renewal of NPDES permits, the approach provides a potential mechanism to integrate point and nonpoint source pollutant control programs in each of the 17 major basins within the State. However, it is unclear how the State will address opportunities to reduce pollution from existing nonpoint sources and the program does not include a schedule for implementing appropriate controls. C. CONSTRUCTION SITE CHEMICAL CONTROL FINDING: North Carolina's program does not include management measures in conformity with the 6217(g) guidance. North Carolina has identified backup enforceable policies and mechanisms to implement the management measure, but has not demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITIONS: Within two years, North Carolina will include in its program management measures for construction site chemical control in conformity with the (g) guidance. Within one year, North Carolina will develop a strategy ( in accordance with Section XIV, page 14) to ensure implementation of the management measure throughout the 6217 management area. RATIONALE: In its program submittal, North Carolina cites the State's water quality standards and the Oil Pollution and Hazardous Substances Control Act as enforcement authorities for this management measure. However, the State has not demonstrated that these authorities will achieve implementation of controls for construction site chemicals throughout the 6217 management area. D. NEW and OPERATING ONSITE DISPOSAL SYSTEMS (OSDS) FINDING: North Carolina's program includes management measures in conformity with the 6217(g) guidance, except it does not provide for (1) adequate separation distances between OSDS system components and groundwater that is closely hydrologically connected to surface waters, (2) measures for inspection and maintenance of OSDS serving single family residences, and (3) denitrifying systems where nitrogen-limited surface waters may be adversely affected by excess nitrogen loadings from OSDS. North Carolina's program includes enforceable policies and mechanisms to ensure implementation of the measures throughout the 6217 management area. CONDITION: Within two years, North Carolina will include in its program management measures in conformity with the 6217 (g) guidance to provide (1) adequate separation distances between OSDS system components and groundwater that is closely hydrologically connected to surface waters, (2) measures for inspection and maintenance of OSDS serving single family residences, and (3) denitrifying systems where nitrogen-limited surface waters may be adversely affected by excess nitrogen loadings from OSDS. RATIONALE: Except for the conditions noted above, North Carolina has a comprehensive regulatory program for the location, design, installation, and inspection and maintenance of onsite disposal systems. For example, the State inspects all OSDS larger than single family (Type II) every five years, but does not have a program to ensure inspection of OSDSs serving single family residences. The State's requirement that allows a vertical separation distance of 12" between the nitrification field and either wet or otherwise unsuitable soils is inadequate to meet the new OSDS management measure, which requires that OSDS be designed and sited at a density so as not to adversely affect surface waters or ground water that is closely hydrologically connected to surface waters. In addition, the State's program does not require measures to ensure the reduction of nitrogen loadings where nitrogen-limited surface water may be adversely affected by excess nitrogen loadings from ground water. E. POLLUTION PREVENTION FINDING: North Carolina's program includes management measures in conformity with the 6217(g) guidance. RATIONALE: In its program submittal, North Carolina describes a number of existing programs and efforts supported by the State to encourage pollution prevention, including the Pollution Prevention Pays (PPP) Program, which provides technical and educational assistance to industries, local governments, and landowners on methods of waste reduction. NOAA and EPA encourage the State to include additional efforts in this program to more directly address pollution reduction opportunities for individuals, such as the application and disposal of garden care products, and the disposal of pet waste. F. ROADS, HIGHWAYS, AND BRIDGES FINDING: North Carolina's program includes management measures for roads, highways, and bridges in conformity with the 6217(g) guidance, except for the runoff systems management measure, for which the State is currently in the process of developing a program. North Carolina's program includes enforceable policies and mechanisms that ensure implementation of the management measures. CONDITION: Within three years, North Carolina will include in its program management measures for runoff systems in conformity with the 6217 (g) guidance. RATIONALE: North Carolina has established requirements and procedures for review and approval of all land disturbing activities (more than 1 acre) by the Sediment Control Commission and Coastal Resources Commission (CRC) (G.S.  113A-50 to 71 and 113A-107 to 126). The Sediment Control Commission has delegated responsibility to the North Carolina Department of Transportation (NCDOT) to implement construction and maintenance programs for State roads, highways and bridges and to provide guidance for local government programs. The Sediment Control Commission can delegate approval to local governments that request delegation, and remains responsible for developments in local areas without delegation. CAMA permits are required within the existing coastal zone for activities affecting the AECs, and the activity must also be consistent with the coastal counties' local land use plans. The Sediment Control Commission and CRC, as well as delegated agencies, have the authority to inspect, fine, require restoration of damaged areas, and issue stop work orders. NCDOT has developed standard contract specifications, planning and design manuals (including guidance for stormwater management), and training programs. NCDOT also provides local agencies training and education. North Carolina is developing a program which will conform to the roads, highways, and bridges runoff systems management measure. This program, being developed by the North Carolina Division of Environmental Management and NCDOT Division of Highways, includes a plan to monitor, evaluate, and improve the quality of runoff (discussed in Appendix J of the program submittal). V. MARINAS AND RECREATIONAL BOATING FINDING: North Carolina's program includes management measures in conformity with the 6217(g) guidance, except for fueling station design. The program includes enforceable policies and mechanisms to ensure implementation, except the State has not established authority to implement the boat operation measure. CONDITION: Within two years, the State will include in its program management measures for fueling station design in conformity with the 6217 (g) guidance and enforceable policies and mechanisms to implement the boat operation management measure. RATIONALE: The State's program is implemented through CAMA, which includes the major development permit process for new, expanding, and existing marinas and mooring fields. Management measures not addressed in CAMA permits, except for fueling station design, are covered under general NPDES stormwater permits and the general and specific use standards for marinas established under Title 15A of the North Carolina Administrative Code. Additionally, the State needs to establish the authority to implement the boat operation management measure. NOAA and EPA encourage the State to develop an operation and maintenance BMP manual as a reference for marina operators and boaters in understanding and applying good management practices at marinas. A BMP manual could clearly explain the objectives of fish waste management, maintenance of sewage facilities, recycling programs, and boat operation, as well as other practices. VI. HYDROMODIFICATION FINDINGS: North Carolina's program includes management measures in conformity with the 6217(g) guidance, except that the program does not include management measures for chemical and pollutant control at dams and does not include a process to identify and develop strategies to solve existing nonpoint source problems caused by streambank and shoreline erosion that do not come up for review under existing permit authorities. The program includes enforceable policies and mechanisms to ensure implementation of the management measures. CONDITION: Within three years, North Carolina will include in its program management measures in conformity with the chemical and pollutant control management measure for dams, and streambank and shoreline erosion in conformity with the 6217 (g) guidance. RATIONALE: The CAMA requires major development permits for projects involving channelization, dams, or shorelines in the 20 coastal counties. Applications for major development permits are reviewed for their effects on water quality, designated uses, and habitat. For channelization projects involving mining of coastal resources, a mining permit (G.S. 74-50 et seq.) is issued after evaluating the effect of the proposed activity on wildlife and fisheries. Channelization projects to drain low-lying farmland are no longer condoned, but several projects have been implemented in the coastal counties over past decades, and are still being maintained by drainage districts or county governments. To improve surface water quality and restore instream and riparian habitat on these and other existing modified channels, State agencies are identifying critical areas that will be targeted for water quality improvement, and are utilizing the Agriculture Cost Share Program and Clean Water Act 319 grants to install BMPs. NOAA and EPA commend this approach and encourage the State to pursue full implementation of the channelization management measures in existing agricultural channelization projects. The State is encouraged to complete its development of the Use Restoration Waters (URW) classification, and to further apply this mechanism to ensure implementation of BMP's for nonpoint sources in areas where water quality is continuously impaired. North Carolina's Dam Safety Law (G.S. 143-215.23 through 215.37) and Sedimentation Pollution Control Act implement the management measure for erosion and sediment control at dams. The implementing regulations for the Dam Safety Law require sediment controls for construction and repair of dams in accordance with the Sedimentation Pollution Control Act (NCAC T15A: 02K. .0210). Regulations implementing the Sedimentation Pollution Control Act require sediment and stormwater controls for land disturbance of greater than one acre. The State partially implements the management measure for chemical and pollutant control at dams through controls on the storage, handling, and disposal of solid and hazardous waste. North Carolina implements the management measures for protection of surface water quality and habitat from the effects of dam operation by adding conditions to permits for dam repair, maintenance, and operation that are necessary to ensure that stream classifications, water quality standards, and aquatic habitat requirements are met and maintained. Management measures for shorelines and streambanks are implemented partly by the CAMA major development permits for shoreline projects in the 20 coastal counties, which can require that natural features on shorelines serving a nonpoint source function are preserved. Standards for erosion and sedimentation control further help to direct stormwater away from shorelines and streambanks. Elements of the management measure to protect shoreline features serving a nonpoint source function are also implemented through the State's regulation of activities in coastal marshes which can prevent their destruction. The State does not have a process to identify and develop strategies to solve existing nonpoint source problems caused by streambank and shoreline erosion that do not come up for review under existing permit authorities. VII. WETLANDS, RIPARIAN AREAS AND VEGETATED TREATMENT SYSTEMS FINDING: North Carolina's program includes management measures in conformity with the 6217(g) guidance and enforceable policies and mechanisms for the protection of coastal wetlands and riparian areas in the State's designated Areas of Environmental Concern. North Carolina's program does not include enforceable policies and mechanisms to ensure implementation of the management measure for the protection of wetlands and riparian areas throughout the 6217 management area, i.e., outside of the designated Areas of Environmental Concern. CONDITION: Within three years, North Carolina will include in its program enforceable policies and mechanisms to ensure implementation of the management measures for wetlands, other than those identified as Areas of Environmental Concern under the State's Coastal Area Management Act, and riparian areas throughout the 6217 management area. RATIONALE: Among other critical areas, the State designates all tidal wetlands as Areas of Environmental Concern and requires that activities affecting these areas receive a permit under CAMA. Outside of the Areas of Environmental Concern, local and county governments also provide protection of coastal wetlands and riparian areas through comprehensive local land use plans. The State also implements management measures for protection of wetlands and riparian areas through other mechanisms, including: (1) the Sedimentation Pollution Control Act, which imposes especially rigorous controls in sensitive watersheds, and buffers around land-disturbing activities; (2) the Stormwater Control Program, which requires treatment of wet weather flows before they carry pollutants into wetlands; (3) the DCM's Wetlands Conservation Plan functional assessment of individual wetlands, which is improving the review of 404 permit applications, and (4) the development and implementation of land-use strategies by State and local governments. Amendments proposed in 1995 to surface water quality standards would increase the State's ability to protect the physical characteristics and water quality functions of wetlands. As the State acknowledges, North Carolina does not currently have a program to apply management measures to the protection of nontidal freshwater wetlands. It is important that the State develop and implement management measures backed with enforceable policies and mechanisms for nontidal freshwater wetlands, in view of the broad extent of these wetlands, particularly within the State's coastal area, and the importance of these wetlands in headwater forests to slow and retain floodwaters, to remove pollutants before they enter coastal waters farther downstream, and to stabilize streambanks, helping to control erosion and sedimentation in rivers and lakes. Management measures promoting restoration of wetlands and riparian areas are implemented through CAMA, which provides broad authority for the State to require mitigation for projects that impact tidal wetlands. Demonstration projects involving wetlands restoration have also been initiated by the State utilizing opportunities with the NC DOT, the USDA PL-566 Watershed Program, and several non-profit organizations. Management measures promoting the use of vegetated treatment systems are implemented through the Agriculture Cost Share Program, and Stormwater Runoff Programs, which encourage treatment of runoff by vegetated treatment systems or by sedimentation ponds. VIII. ADMINISTRATIVE COORDINATION FINDING: North Carolina's program establishes mechanisms to improve coordination among State agencies and between State and local officials. RATIONALE: The State has integrated the administrative coordination for its Coastal Nonpoint Program into coordination efforts through its water quality programs - mainly, the Nonpoint Source Program and Basinwide Planning Initiative. First, the State Nonpoint Source Program developed a coordination mechanism whereby each lead nonpoint agency has a representative that serves on a Statewide nonpoint workgroup. The workgroup is responsible for revising the Nonpoint Source Program and reviewing applications for Section 319 funding. The workgroup is served by teams that develop technical information about nonpoint sources on a riverbasin basis - e.g., identifying future monitoring sites, conducting specific assessments of nonpoint source pollution controls in targeted watersheds, etc. This information will also be used in the Basinwide Planning Initiative to ensure each lead agency is influencing the basinwide planning process. Workgroup participants also provide a link with related regional offices, which in turn provide information to local governments and private groups. IX. PUBLIC PARTICIPATION FINDING: North Carolina's program provides opportunities for public participation in the development and implementation of its Coastal Nonpoint Program. RATIONALE: North Carolina's program submittal describes activities that provided opportunities for public participation in the development and implementation of its Coastal Nonpoint Program. Opportunities for public participation include various presentations made by the State about its coastal nonpoint program and discussions about the program with environmental groups; development and distribution of newsletters by University of North Carolina Sea Grant and the State Division of Coastal Management to all affected public and governmental organizations within NOAA's recommended 6217 management area; and targeted public and agency review of each portion of the State's program. X. CRITICAL COASTAL AREAS FINDING: North Carolina's program identifies and includes a process for the continuing identification of critical coastal areas adjacent to impaired and threatened coastal waters. RATIONALE: The State's Division of Coastal Management and Division of Environmental Management have agreed on a watershed-based method to identify critical coastal areas. The State will use GIS-mapping process to identify high, medium, and low priority waters. High priority watersheds will include monitored streams that do not support designated uses due to nonpoint pollution; monitored streams that are partially supporting designated uses or have designated uses that are threatened and have high predicted loadings of one or more pollutants; and streams that are unusually sensitive as documented by special studies. Medium priority watersheds will include those partially supporting designated uses, and low priority watersheds will include those fully supporting uses or those that have been described as impacted on the basis of evaluated data or best professional judgment. Small watersheds (14-digit hydrologic units) that are adjacent to waters identified as high or medium priority will serve as the critical coastal areas. In addition, streams designated as medium or low priority may be reconsidered as high priority at any time by the State if special studies support such a change in priority. The State's approach follows the second approach described in the program guidance whereby a State relies on site-specific evaluations to determine the extent of the critical coastal areas. XI. ADDITIONAL MANAGEMENT MEASURES FINDING: North Carolina's program provides for implementation and continuing revision of additional management measures applicable to critical coastal areas and cases where Section 6217(g) management measures are fully implemented but water quality threats or impairments persist. RATIONALE: North Carolina submitted an advisory opinion from its Attorney General's Office outlining the State's authority to adopt site-specific BMPs where water quality is below that required by existing water quality classifications and standards. The clearest authority is found in the State's stormwater runoff law. The State reports that its ability to adopt site specific BMPs will be the authority most relied upon to adopt additional management measures. Additionally, the State reports on its authority to establish a new supplemental water quality classification such as Use Restoration Waters (URW). The URW classification would be used by the State's Environmental Management Commission to require the development of management strategies targeting all sources of impairment in areas where use support is persistently impaired. URW management strategies would require a site-specific mixture of best management practices and wastewater management strategies to restore designated uses. The State also proposes to establish the URW classification under the CAMA so that both the Coastal Resources Commission and the Environmental Management Commission have authority to ensure that the classification can be applied throughout the State's 6217 management area. NOAA and EPA support both of these approaches. XII. TECHNICAL ASSISTANCE FINDING: North Carolina has included programs that will provide technical assistance to local governments and the public for implementing additional management measures. RATIONALE: North Carolina describes technical assistance programs for each of the nonpoint source categories. For example, technical assistance is provided by the State Division of Soil and Conservation, the State Division of Forest Resources, the State Division of Land Resources, and the State Division of Marine Fisheries. The assistance will include the preparation of guidance documents, manuals, fact sheets, and educational materials; training workshops; and one-on-one assistance by State technical staff. Additional information and education on nonpoint pollution is accomplished by the Division of Environmental Management's Nonpoint Source Program and the North Carolina Cooperative Extension Service. XIII. MONITORING FINDING: North Carolina's program includes a plan to assess over time the success of management measures in reducing pollutant loads and improving water quality. RATIONALE: In the program submittal and additional information transmitted by the State, North Carolina identifies a range of existing and new monitoring efforts to assess over time the effectiveness of best management practices. These best management practices studies are in several cases equivalent to evaluations of section 6217 management measures. In addition, the State has identified watershed and ambient monitoring efforts that, in combination, should allow the State to determine if management measures are reducing loads and improving water quality. The State is encouraged, however, to formalize the linkage between section 6217 activities and monitoring activities to ensure that such monitoring will enable the State to assess over time the extent to which implementation of management measures is reducing pollution loads and improving water quality. XIV. STRATEGY AND EVALUATION OF BACKUP AUTHORITIES Within one year, North Carolina will develop a strategy to implement the management measures for agriculture, and urban erosion and sediment control and construction site chemical control throughout the 6217 management area. This strategy will include a description and schedule for the specific steps the State will take to ensure implementation of the management measure; 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 State's ability to achieve implementation of the management measure using the described approach. In order to evaluate the adequacy of this strategy, North Carolina will also develop and apply credible survey tools to demonstrate the ability of the State'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 State's approach has been successful or whether new, more specific authorities will be needed.
