FINDINGS FOR THE NEW HAMPSHIRE COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the State of New Hampshire pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the New Hampshire Coastal Nonpoint Pollution Control Program, Final Program Submittal, July 1995 and supplemental material provided by New Hampshire 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 New Hampshire 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 New Hampshire 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 New Hampshire's program. It also provides the rationale for the findings and includes conditions that will need to be met for New Hampshire to receive final approval of its program. We recognize that New Hampshire has already proposed changes for its program that would, if finalized, ensure the implementation of the management measures in conformity with the 6217(g) guidance. In those cases, the conditions are based on the State's proposed changes. Timeframes for meeting conditions will become effective upon the date stamped on 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 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 New Hampshire Coastal Nonpoint Pollution Control Program, Final Program Submittal, 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 New Hampshire 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 & Watershed Protection Division Nonpoint Source Control Branch 401 M St., SW (4503-F) Washington, DC 20460 Contact: Kristen Martin (202/260-7108) NOAA/Office of Ocean and Coastal Resource Management Coastal Programs Division SSMC-4, N/ORM3 1305 East-West Highway Silver Spring, MD 20910 Contact: Dwight Reynolds (301/713-3105, x154) U.S. EPA Office of Ecosystem Protection New Hampshire State Unit JFK Federal Building Boston, MA 02203 Contact: Warren Howard (617/565-3515) I. BOUNDARY FINDING: New Hampshire's state-designated boundary corresponds with the boundary recommended by NOAA. This 6217 management area 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 New Hampshire. RATIONALE: New Hampshire recognizes that the existing coastal zone does not encompass the existing and future land and water uses that are likely to have a significant impact on the State's coastal waters. In the program submittal, New Hampshire proposes to adopt NOAA's recommended management area, the entire coastal watershed, but recognizes two zones (A and B) for the purpose of setting program priorities and phasing program implementation. Most of the existing State programs that will be used to implement the management measures apply statewide, but New Hampshire will initially focus certain enhanced program activities in Zone A. NOAA and EPA encourage the State to continue program development, implementation, and evaluation efforts throughout the coastal watershed to ensure sufficient control of land and water uses that have or are reasonably expected to have a significant impact on the coastal waters of New Hampshire. II. AGRICULTURE FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance, except for nutrient management. The State has identified backup enforceable policies and mechanisms, but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. New Hampshire has provided sufficient justification to support an exclusion of irrigated agricultural lands from the irrigation management measure. CONDITION: Within two years, New Hampshire will include in its program management measures in conformity with the 6217(g) management measure for nutrient management. Within one year, New Hampshire will develop a strategy (in accordance with Section XIV, page 16) to implement the agricultural management measures throughout the 6217 management area. RATIONALE: New Hampshire has listed the six applicable 6217(g) agricultural management measures in its program submittal, and has identified the programs that will be used to implement the measures. New Hampshire has also identified, in the program submittal and in supplemental information provided by the State subsequent to the program submittal, best management practices (BMPs) that can be used to achieve the agricultural management measures, except for nutrient management. For storage of runoff and facility wastewater, New Hampshire's supplemental material indicates that the State applies several BMPs to meet both the small and large confined animal facilities management measures. Specifically, the supplement describes the USDA/Natural Resources Conservation Service design criteria for waste storage systems that require accommodation of the 25-year, 24-hour storm. NOAA and EPA interpret that description as setting the minimum requirements for system design in the State of New Hampshire. Similarly, the State's supplement indicates that operation of waste storage ponds is in accordance with an overall waste management plan for the facility. However, supplemental information on nutrient management is largely related to nutrient management planning for sludge application. The New Hampshire agricultural BMP manual includes practices that address many elements of the nutrient management measure, but it does not include development of a nutrient management plan for application of animal waste. New Hampshire has identified backup enforceable policies and mechanisms to ensure implementation of the agricultural management measures. Under the Water Pollution and Waste Disposal Law (RSA 485-A:12), pollution sources which lower the quality of classified waters below minimum requirements must abate such pollution within a specified time period. If the responsible person fails to take action to abate the pollution, then the New Hampshire Department of Environmental Services (NHDES) may seek appropriate action in the courts. The classification standards indicate that this authority can be used to address problems associated with all of the agricultural management measures. In accordance with the Manure, Compost and Fertilizer Handling Program (developed under RSA 431:33-35), farmers who do not comply with BMPs are subject to enforcement actions by NHDES under the authority of RSA 485-A:12 (water quality standards) and/or by the local health officer under RSA 147:4 (nuisance law). Provisions under the Nuisance Liability of Agriculture Operations (RSA 432:34) exempt agricultural operations from nuisance liability when they conform to federal, state and local laws, rules and regulations. This exception does not apply when the operation is determined to be injurious to public health or safety, or if a nuisance results from negligent or improper operation. Based on the small number of farms within the management area that meet the applicability thresholds for the large and small confined animal facility management measures, New Hampshire should be able to identify measurable results which, if achieved, will demonstrate the State's ability to achieve implementation of the management measures using the described approach. Under the Pesticide Rules, private applicators must agree to report all pesticide use to obtain a permit for use of general-use pesticides. These records are required to be made available to the State annually. Cease and desist orders can be issued to any person in violation of the rule or permits issued under the rule. Under the Fill and Dredge in Wetlands (RSA 482-A) statute, NHDES can require corrective action for any soil erosion problems that impact wetlands. The Terrain Alteration law (RSA 485-A:17) provides limited authority to address water quality problems caused by tillage. III. FORESTRY FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. New Hampshire has provided sufficient justification to support exclusions for the Fire Management and Site Preparation/Forest Regeneration management measures. RATIONALE: The New Hampshire BMP manual for forestry, Best Management Practices for Erosion Control on Timber Harvesting Operations in New Hampshire, has adequate standards and specifications to implement the 6217(g) management measures for forestry. Existing State authority under Env-Ws 415.04 (referenced on page 35 of the submittal) requires each logger to obtain a site specific permit and agree to "abide by the Best Management Practices (BMP) for the protection of water quality" when the logger signs a required Notice of Intent to Cut (RSA 79:10). The forestry BMP manual is also enforceable through RSA 485-A:17, which requires a permit for the transportation of forest products, but automatically grants the permit to loggers when they sign the Notice of Intent to Cut form and agree to follow the BMP's. According to the New Hampshire Technical Input Committee for the forestry management measures, Site Preparation/Forest Regeneration and Fire Management occur infrequently, if at all. The average size of forest fires in the State is less than 0.5 acres and prescribed burns are generally done only in the White Mountains National Forest, outside the NOAA- recommended 6217 management area. IV. URBAN A. NEW DEVELOPMENT FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance but does not include enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within two years, New Hampshire will amend its program to ensure implementation of this measure throughout the 6217 management area. RATIONALE: In accordance with Env-Ws 415.09(a)13, each site specific plan shall include stormwater drainage calculations for pre- and post-construction, for a storm with a minimum return frequency of once in ten years. This requirement addresses the volume control aspect of the management measure for projects subject to this authority. As described in the program submittal, the State requires a Site Specific permit for larger projects, including all projects on areas greater than 100,000 square feet or 50,000 square feet within 250 feet of protected waters (Env-Ws 415.03). Permits for these projects requires treatment via vegetated swales or sedimentation ponds. Subsequent to the program submittal, New Hampshire provided supplemental information that includes rule changes to Env-Ws 415. Specifically, Env-Ws 415.11 includes new language describing the full range of permanent methods for protecting water quality after development has been completed. NOAA and EPA agree that the new language provides a set of practices that achieve 80% removal of total suspended solids (TSS) for those activities subject to the Site Specific Permit Program. The Site Specific permit is not in conformity with the 6217(g) guidance applicability statement in that enforceable policies and mechanisms are not applicable to sites under 100,000 square feet or 50,000 square feet within 250 feet of protected waters. For sites falling below the Site Specific permit threshold and for activities located outside of the State protected shoreland, New Hampshire is proposing to rely on stormwater management ordinances developed by municipalities, using their subdivision, site plan review, and shoreland protection authorities to require stormwater management measures. However, New Hampshire cannot require local stormwater management. The State has begun a survey of local governments and found that many have stormwater programs that meet the 80% TSS standard. We encourage the State to work with other local governments and to ensure that the new development management measure is implemented throughout the 6217 management area. B. WATERSHED PROTECTION AND EXISTING DEVELOPMENT FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. RATIONALE: The program submittal describes a number of programs in New Hampshire that can be used to implement these management measures, including the Coastal Watershed Program, the Watershed Approach to Abate Pollution, and the Rivers Management and Protection Program. The goals of the Coastal Watershed Program projects are to identify the water quality impacts of existing nonpoint sources and then develop recommendations, for local implementation, to address existing and future nonpoint sources. As described in supplemental material provided by the State, the NHDES Surface Water Quality Bureau has issued its 1996 Coastal Basin Nonpoint Source Pollution and Abatement Plan which outlines a three-year action plan for coastal watersheds. Working with local governments, New Hampshire proposes to use the plan and its recommendations to identify areas which are being adversely impacted by development and ensure that appropriate site restrictions are put in place to protect areas that provide important water quality benefits. The first project, focusing on the Exeter and Squamscott River subwatershed, was completed in December 1995. This study concluded that there are nonpoint pollution problems in the watershed, arising mainly due to stormwater runoff from urban areas, septic systems, shoreline development, and agricultural runoff. The New Hampshire Coastal Program is working with NHDES and local governments to implement recommendations of the study, including the need for education, improved local regulations and implementation and future monitoring and management. A series of similar projects is planned in all coastal subwatersheds. We encourage the State to continue this effort and to use experience from the initial projects to further develop a comprehensive watershed protection program. For existing development, the program submittal includes a list of proposed activities, including identifying water quality goals based on local input and taking compliance and enforcement actions as needed, that were scheduled to begin in Spring of 1995 and run for five years in each basin. Based on supplemental information provided subsequent to the program submittal, there are two watersheds for which the State has completed assessment work and developed a list of recommendations for locals to address problems from existing sources. The State has also provided a list of remaining watersheds to be addressed in accordance with a proposed schedule. New Hampshire's program submittal includes enforceable policies and mechanisms that can be used to implement these management measures. Authorities under the Site Specific program, the wetlands program (RSA 482-A) and the Comprehensive Shoreland Protection Act restrict disturbance of land in particular geographic areas for particular classes of activities. These authorities can also be used to restrict the siting of roads, highways and bridges. C. SITE DEVELOPMENT FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance but does not include enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within two years, New Hampshire will include in its program enforceable policies and mechanisms to ensure implementation of this measure throughout the 6217 management area. RATIONALE: As described in the program submittal, planning, design, and development of sites is partially addressed by the Site Specific program. Applicants for permits under this program are referred to the Stormwater Management and Erosion and Sediment Control Handbook for Urban and Developing Areas in New Hampshire for appropriate practices. In order to avoid inappropriate development in areas that are susceptible to erosion and sediment loss, the Site Specific program requires permit applicants to provide soils information in order to ensure that BMPs are properly selected and designed for the site. It also seeks to preserve natural drainage systems whenever possible; however, as described above, it does not apply to land disturbances less than 100,000 square feet (50,000 square feet within 250 feet of protected waters). Zoning and land use planning are enabled by the Municipal Subdivision and Site Plan Review Regulations under RSA 674:35- 36 and RSA 674:43-44. These provisions establish the definition for subdivision of land and the criteria that local governments can use in regulating the use of land. However, New Hampshire has not demonstrated that municipal governments consistently require the aspects of the management measure in the review of land development proposals or that such criteria are used widely throughout the 6217 management area. The State has begun a survey of local governments to determine how they review development proposals. Other programs that serve to partially implement this measure include the Wetlands program, which restricts disturbance of wetlands and the tidal buffer zone and discourages the disturbance of the natural integrity of waterbodies, and the Comprehensive Shoreland Protection Act, which restricts disturbances in the protected shoreland. D. CONSTRUCTION SITE EROSION AND SEDIMENT CONTROL FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance but does not include enforceable policies and mechanisms to ensure implementation. CONDITION: Within two years, New Hampshire will include in its program enforceable policies and mechanisms to ensure implementation of this measure throughout the 6217 management area. RATIONALE: Site Specific permits contain erosion control provisions that must be met and applicants are referred to the Stormwater Management and Erosion and Sediment Control Handbook for Urban and Developing Areas in New Hampshire as the technical reference for descriptions of acceptable BMPs. The Handbook includes practices that can be used to implement the elements of this management measure. However, the State does not require an approved erosion and sediment control plan that contains erosion and sediment control provisions for sites that disturb less than 100,000 square feet (50,000 square feet within the protected shoreline) . The Office of State Planning and the Coastal Watershed Program recommend that municipalities require erosion and sediment control plans to be in place prior to land disturbance, but there is not a mechanism to ensure that local governments do so. Based on supplemental information provided by the State, several towns have chosen to require a plan, but there is variability in these requirements and they may not meet the applicability thresholds described in the (g) guidance. E. CONSTRUCTION SITE CHEMICAL CONTROL FINDING: New Hampshire's program does not include management measures in conformity with the 6217(g) guidance but includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within one year, New Hampshire will include in its program management measures in conformity with the 6217(g) guidance for construction site chemical control. RATIONALE: Limits on fertilizer application are included in the Stormwater Management and Erosion and Sediment Control Handbook for Urban and Developing Areas in New Hampshire and prohibited in protected areas by the Comprehensive Shoreland Protection Act. Nutrient application rates are also addressed in the Handbook. However, the Handbook does not include specific practices for limiting the application, generation and migration of toxic substances or proper storage and disposal of toxic substances. Based on supplemental material provided by the State, the Groundwater Protection Act (RSA 485-C) authorizes the development of BMPs to protect groundwater from potential contamination sources, including above ground storage facilities for oil and hazardous substances, but the State does not yet have a list of practices to address these sources. In both the program submittal and supplemental information, New Hampshire identifies several authorities that can be used to ensure implementation of this management measure. New Hampshire has the ability to ensure that pesticide aspects of the measure are implemented through the State Pesticide Control Program under RSA 430:28-49 and NH CAR Pes 100-1002.17. Action can also be taken in cases where a water quality standard has been violated due to a spill of toxic materials or groundwater contamination. RSA 146-A:3 prohibits the discharge or spillage of petroleum products or by-products onto surface water or ground water of the State, or in areas where it will seep into surface water or ground water. RSA 485-C:11 requires the Division of Water Supply and Pollution Control, Department of Environmental Services to develop and administer BMPs for activities identified as potential contamination sources. The Comprehensive Shoreland Protection Act limits the application of fertilizers in residential areas within the protected shoreland. New Hampshire may wish to consider linking construction site chemical control measures to the process for implementing the construction site erosion control measure above. Such a linkage could provide for incorporation of construction site chemical control practices into sediment and erosion control plans. F. POLLUTION PREVENTION FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance. RATIONALE: New Hampshire's program submittal describes a number of existing efforts, including extensive public education programs and outreach efforts. The State provided a list of publications and outreach activities that address each of the components of the management measure. G. NEW AND OPERATING ONSITE DISPOSAL SYSTEMS FINDING: New Hampshire'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 throughout the 6217 management area. RATIONALE: The State has a comprehensive set of Administrative rules (Env-Ws 1000) and Revised Statutes (RSA 485-A) relative to individual sewage disposal system design, location, and operation and maintenance. The Bureau has 25 inspectors, in six regional offices. Inspections are required pre- and post-construction and for accumulation of sludge and surface scum at least once every year (Env-Ws 1023.01). Based on information provided by New Hampshire in a section 309 grant performance report, RSA 485-A:39 requires that a septic system site assessment be performed at the time of sale of waterfront property. The performance report summary also indicates that in June 1996, the State passed Chapter 219, expanding the definition of developed waterfront property to include land contiguous to or within 200 feet of tidal waters and which uses a septic disposal system. The assessments are required to include detailed information on the size of the tank, type, age and location of the system, any malfunctions and whether the system meets current OSDS standards. This gives potential buyers information about the quality of on-site septic systems and provides a mechanism by which the State can ascertain whether systems are failing. According to the State, there are few indicators that the State's tidal waters are nitrogen-limited. Subject to funding, the New Hampshire Coastal Program will pursue research designed to determine nitrogen-loading or nitrogen-concentration thresholds for New Hampshire's coastal waters. We encourage the State to pursue efforts to study the existence of nitrogen-sensitive waters. H. ROADS, HIGHWAYS, AND BRIDGES FINDING: New Hampshire's program includes management measures for roads, highways, and bridges in conformity with the 6217(g) guidance for all Department of Transportation (NHDOT) constructed and maintained projects. New Hampshire's program is not yet in conformity with the operation and maintenance and runoff systems management measures for non-NHDOT roads, highways, and bridges. New Hampshire's program includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area, except for siting, design, and construction of roads, highways, and bridges in towns and municipalities. CONDITION: Within three years, New Hampshire will complete and implement its planned program to be in conformity with the operation and maintenance and runoff systems management measures for all non-NHDOT roads, highways and bridges. Also within three years, New Hampshire will include in its program enforceable policies and mechanisms to ensure implementation of the management measures in towns and municipalities throughout the 6217 management area. RATIONALE: New Hampshire DOT has a comprehensive program which uses existing authorities, contract specifications, state design and reviews of contractor designs, consultations, and inspections to meet the management measures for projects under their jurisdiction. Many excellent guidance manuals are available. As described above in the rationale for the new development management measure, New Hampshire issues Site Specific permits for non-NHDOT projects that disturb areas over 100,000 square feet or 50,000 square feet in the protected shoreland-within 250 feet of public waters. Operation and maintenance and runoff management system management measures for all non-NHDOT roads (without thresholds) is proposed to be accomplished using a program involving education and technology transfer. NH DOT is in the process of developing a set of policies, procedures and specifications for pollution prevention. The Coastal Nonpoint Program plans to participate in the development of new procedures and standards and anticipates that a new manual will be finalized within two years. NOAA and EPA encourage the State to complete this effort to meet the condition above. New Hampshire's program includes enforceable policies and mechanisms through Env-Ws, part 415 and RSA 485 which provide general and specific permit authority. NHDOT standard contract specifications provide the ability to oversee development of roads, highways, and bridges, including inspections and stop work orders, if necessary. Siting, design, and construction of non-NHDOT roads and bridges disturbing smaller areas is the responsibility of local towns and municipalities under RSA 674:35-36 and 674:43-44 which gives them authority to regulate these activities. These local entities, however, are not required to develop and use such authorities. Supplemental material provided by the State describes the State Aid to Highways Program and Block Grant Aid Program, both of which provide State funds for local roads, but the State has not identified any specific mechanisms within these funding programs that might be used to ensure that local governments implement the management measures. The summary of the Block Grant Aid Program indicates that "[M]uch discretion exists for the municipality to decide how to utilize these funds." V. MARINAS AND RECREATIONAL BOATING FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation, except for the operation and maintenance management measures. The State has identified backup enforceable policies and mechanisms for operation and maintenance, but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within one year, New Hampshire will develop a strategy (in accordance with Section XIV, page 16) to implement the marina operation and maintenance management measures throughout the 6217 management area. RATIONALE: New Hampshire has developed a guidance document entitled Best Management Practices for New Hampshire Marinas that includes management measures in conformity with the 6217(g) guidance. NOAA and EPA understand that this document has been distributed to marina owners and operators. Authority under RSA 482-A:3,1 provides the Wetlands Bureau with jurisdiction over surface waters and adjacent banks throughout the State. The State Wetlands Bureau regulates and issues permits for developments in freshwater and saltwater wetlands, including areas up to 100 feet landward from the highest tide line in coastal areas. Permits issued under this authority provide a mechanism to ensure that the siting and design management measures are implemented. The program submittal describes a pending set of proposed rule changes to the Wetlands Bureau Rules that may provide an opportunity to more fully implement the siting and design management measures. NOAA and EPA encourage New Hampshire to pursue these changes, including consideration of a possible link between existing permitting programs and the newly published marina BMP manual. For the operation and maintenance management measures, New Hampshire proposes to rely heavily on the Marina BMP Manual. New Hampshire has also proposed to use its State water quality standards a backup authority. RSA 485-A:12 provides that NHDES may require any person to correct water quality standards violations, and RSA 485-A:15 prohibits the placing of debris or similar litter into the surface waters of the state. According to supplemental material provided by New Hampshire, other relevant authorities include administrative rule 602.04, prohibiting fish dumping by commercial fishing vessels, RSA 146-A:3 & 5, prohibiting discharge or spillage of oil into the surface waters of the state and a requirement to notify DES if such a spillage does occur, and RSA 270-D:2 VI(a)(3), which requires decreased boating speed within 150 feet from shore. New Hampshire DES will also be distributing boater and marina BMP information in the coastal watersheds over the next three years as part of its 1996 Coastal Basin Nonpoint Source Pollution Assessment and Abatement Program, in order to encourage boater implementation of the marina operation and maintenance management measures. NOAA and EPA encourage the State to continue with efforts to educate the boating public regarding applicable BMPs and to consider providing a better linkage between the above listed permitting programs and the Marina BMP manual. VI. HYDROMODIFICATION FINDINGS: New Hampshire's program includes management measures in conformity with the 6217(g) guidance, except for chemical and pollutant control at dams and the lack of a process to improve surface water quality and restore instream and riparian habitat through the operation and maintenance of existing modified channels. New Hampshire's program includes enforceable policies and mechanisms to ensure implementation, except for dam operation. CONDITION: Within three years, New Hampshire will include in its program management measures for chemical and pollutant control at dams and a process to improve surface water quality and restore instream and riparian habitat through the operation and maintenance of existing modified channels. Within three years, New Hampshire will include in its program enforceable policies and mechanisms for dam operation. RATIONALE: The Wetlands Bureau permitting process and Comprehensive Shoreland Protection Act implement most aspects of the hydromodification management measures. The review of permit applications for channelization considers criteria related to water quality impacts. The review of permits for bank stabilization activities promotes the use of natural vegetation, diversion of stormwater away from the bank face, and proper design of engineering structures where appropriate. The Comprehensive Shoreland Protection Act establishes a protected shoreland within 250 feet of the reference line of public waters; and establishes building set backs and a protected 150-foot natural woodland buffer. New Hampshire has proposed to implement the management measure for chemical and pollutant control at dams through the Groundwater Protection Act, which gives the State authority to inspect potential contaminant sources, including fueling and maintenance of excavation and earthmoving equipment, for compliance with state BMPs. However, as described above for urban construction site chemical control, the State does not yet have a list of practices to address these sources. The management measure for protection of surface waters and instream and riparian habitat from the effects of dam operation will be implemented through the Water Management Bureau, which registers large water withdrawals. Rivers Management and Protection Program Rules are also being developed to protect instream flows, which (in supplemental information provided by New Hampshire) the State has indicated will be applied to all rivers in the future. NOAA and EPA anticipate that these rules can be used to meet the condition above for enforceable policies and mechanisms for dam operation. Activities on land within 100 feet of the highest observable tide line for tidal wetlands, or immediately adjacent to nontidal wetlands, are subject to the New Hampshire Wetlands Bureau's authority. Exemptions to the Shoreland Protection Act include the clearing of land for agricultural utilization under some circumstances. NOAA and EPA encourage New Hampshire to examine the effects of these exemptions on surface water quality in order to ensure that these activities do not have a significant impact on coastal waters. VII. WETLANDS, RIPARIAN AREAS AND VEGETATED TREATMENT SYSTEMS FINDING: New Hampshire's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area, except that there are exemptions which may preclude the State from fully implementing the management measure for protection of wetlands and riparian areas. CONDITIONS: Within three years, New Hampshire will eliminate or revise current exemptions to the Comprehensive Shoreland Protection Act or demonstrate that the exemptions do not preclude the State from fully implementing the management measures throughout the 6217 management area. RATIONALE: The Wetlands Bureau permitting process and Comprehensive Shoreland Protection Act implement most aspects of the management measure for protection of wetlands and riparian areas. The review of permit applications for dredging activities in wetlands considers criteria related to nonpoint source functions. RSA 483-A:7 allows municipalities to designate prime wetlands. Any activities in prime wetlands receive a higher level of scrutiny by state permitting agencies. The Comprehensive Shoreland Protection Act establishes a protected shoreland within 250 feet of the reference line of public waters; and establishes building set backs and a protected 150-foot natural woodland buffer. However, exemptions to the Comprehensive Shoreland Protection Act include the clearing of land for agricultural utilization under some circumstances, and areas which local governing bodies have found to have special local urbanization conditions. As currently written, exemptions in these authorities are likely to significantly restrict the State's ability to fully implement the management measure for wetlands and riparian area protection. NOAA and EPA encourage New Hampshire to continue its development and implementation of the Wetlands and Riparian Areas Project, which will recommend a model ordinance concerning wetland and riparian area protection to municipalities for voluntary adoption. This will assist the State in addressing problems that do not come up for review under existing authorities. NOAA and EPA also encourage New Hampshire to pursue revisions to Chapter 400 (Shoreline Structures) which would help the State to further address the management measure for protection of wetlands and riparian areas. Management measures promoting restoration of wetlands and riparian areas will be implemented through the Coastal Program's utilization of Coastal Zone Management Act 306 and 306A pass through funding, and other management grants. The Coastal Program also completed a marsh restoration project funded by the U.S. Fish and Wildlife Service. The Wetlands Bureau also promotes restoration of damaged and destroyed wetlands as a means of mitigation for projects that impact wetlands. Management measures promoting the use of vegetated treatment systems will be implemented through the Site Specific Program, which requires treatment of runoff from paved surfaces, either by vegetated treatment systems or by sedimentation ponds. VIII. ADMINISTRATIVE COORDINATION FINDING: New Hampshire's program establishes mechanisms to improve coordination among State agencies and between State and local officials. RATIONALE: New Hampshire is relying primarily on existing programs and enforceable polices and mechanisms to implement the management measures. The program submittal addresses administrative coordination in Section 3, which describes how the coastal nonpoint program is coordinated with State and local water quality programs and the New Hampshire Coastal Program. Section 4.6 lists the mission, structure, and operation of each agency involved in either the development or implementation of the coastal nonpoint program. Section 319 program staff have worked closely with 6217 staff on all aspects of program development. These staff administer grants that may be used for implementation of management measures and conduct nonpoint source monitoring and assessment projects. The statewide nonpoint source committee also provides a vehicle for discussion of efforts to coordinate nonpoint source control efforts on a statewide basis. IX. PUBLIC PARTICIPATION FINDINGS: New Hampshire's program provides opportunities for public participation in the development and implementation of the coastal nonpoint program. RATIONALE: New Hampshire established Technical Input Committees composed of State and federal agencies, interest groups, and members of the regulated community. These Committees reviewed and commented on the State's Coastal Nonpoint Pollution Control program. New Hampshire also has provided, and continues to provide, information on the Coastal Nonpoint Pollution Control program through articles in its Coastal Program newsletter which is circulated to public libraries and municipal officials. The State has provided for public review and comment, and has demonstrated a continuing commitment to public education throughout development of this program. X. TECHNICAL ASSISTANCE FINDINGS: New Hampshire has included programs that will provide technical assistance to local governments and the public for implementing additional management measures. RATIONALE: New Hampshire has utilized the funds from various assistance programs to focus technical assistance efforts on numerous issues relative to nonpoint source pollution in coastal watersheds, shoreland protection, and rivers management and protection. The State intends to continue its effort of working closely with local land boards and conservation organizations in designing coastal watershed projects. The goals of the watershed projects are to demonstrate the water quality impacts of existing nonpoint sources and to develop recommendations for local implementation to address existing and future nonpoint source pollution. XI. ADDITIONAL MANAGEMENT MEASURES FINDING: New Hampshire's program provides for the identification of additional management measures and the continuing revision of management measures applicable to critical coastal areas and cases where (g) measures are fully implemented but water quality threats or impairments persist. RATIONALE: New Hampshire's description of its Comprehensive Shoreland Protection Program, Wetlands Program, Coastal Watershed Program activities, and Nonpoint Source Pollution Management Plan identify activities that are currently underway or planned to address critical coastal areas and areas where water quality impairments exist even after (g) management measures or their equivalent have been implemented. In conjunction with the monitoring program, the Coastal Nonpoint Program will rely on periodic reviews of management measure implementation in order to formulate effective and appropriate additional management measures. XII. CRITICAL COASTAL AREAS FINDING: New Hampshire's program identifies and includes a process for the continuing identification of critical coastal areas adjacent to impaired and threatened coastal waters. RATIONALE: New Hampshire has generally followed the first approach described in the program guidance whereby the State has designated a strip of land along the shoreline that extends inland a uniform distance. This strip of land is defined by the jurisdiction of the State's Comprehensive Shoreland Protection Act and includes all land in the 6217 management area that is within 250 feet of tidal waters, fourth-order streams, or great ponds. XIII. MONITORING FINDING: New Hampshire's program includes a plan to assess over time the success of the management measures in reducing pollution loads and improving water quality. RATIONALE: In both the program submittal and in supplemental material provided by the State, New Hampshire describes numerous monitoring programs and how they will be applied to the coastal nonpoint program. As described in the supplemental information, NHDES will assess both water quality and the implementation of best management practices within the Piscataqua and coastal watersheds. Tributary monitoring conducted through the coastal nonpoint program includes seventeen sampling stations that are monitored for a variety of parameters, including nutrients and bacteria. Long term baseline monitoring is also being conducted at three sites within the Great Bay Estuary, providing an opportunity to related land use changes in upper portions of the watershed to water quality and resource changes within the estuary. NOAA and EPA encourage New Hampshire to coordinate monitoring efforts, particularly with respect to monitoring land treatment, in order to further assess the extent to which management measures are reducing pollution loads and improving water quality. XIV. STRATEGY AND EVALUATION FOR BACK-UP AUTHORITIES Within one year, New Hampshire will develop a strategy to implement the management measures for agriculture and marinas operation and maintenance. This strategy will include a description and schedule for the specific steps the State 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 State's ability to achieve implementation of the management measures using the described approach. In order to evaluate the adequacy of this strategy, New Hampshire 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.
