FINDINGS FOR THE MAINE COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the State of Maine pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the Maine Coastal Nonpoint Pollution Control Program, July 1995 and supplemental material provided by Maine 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 Maine 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 Maine 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 Maine's program. It also provides the rationale for the findings and includes conditions that will need to be met for Maine 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 Maine 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 Maine 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: Dov Weitman (202/260-7085) NOAA/Office of Ocean and Coastal Resource Management SSMC-4, N/ORM3 1305 East-West Highway Silver Spring, MD 20910 Contact: Joelle Gore (301/713-3117, ext. 177) U.S. EPA, Region I Office of Ecosystem Protection Maine State Unit, JFK Federal Building Boston, MA 02203 Contact: Sandra Fancieullo (617/565-4426) I. BOUNDARY FINDING: Maine'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 Maine State Planning Office, Department of Environmental Protection, United States 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 determine an appropriate 6217 management area boundary to protect the State's coastal waters from nonpoint source pollution. Maine's program will include management measures in conformity with the (g) guidance, and enforceable policies and mechanisms that ensure implementation of the management measures throughout an expanded 6217 management area. RATIONALE: Maine proposes to include in its 6217 management area all towns that have land areas that drain directly to coastal waters. These are defined by the State to mean those land areas that drain to waters downstream of lakes that flush less than 50 times per year or drain to the "major" rivers at or below specific locations listed by the State. Maine proposes to exclude all other areas from its coastal nonpoint program. Maine has not provided sufficient detail on the location of its proposed boundary to enable NOAA and EPA to fully analyze the relationship between land and water uses and coastal waters as described in the March 16, 1995 guidance entitled Flexibility for State Coastal Nonpoint Programs. For example, the State has not identified by name the lakes which are included or excluded from the proposed 6217 management area based on the State's criteria. NOAA and EPA have identified lakes within both the general area of Maine's proposed boundary and the NOAA recommended boundary that are impaired, but are unable to determine whether these lakes are proposed for exclusion under the State's proposal. With regard to the criteria used by Maine to define its boundary, the State has not provided any data to indicate the extent to which pollutants are or may be retained by lakes in Maine's coastal area. While the submittal cites three studies to support the State's argument and states that data show low levels of phosphorus, nitrogen and coliform bacteria at the outlets of lakes, the State has not submitted the studies or data to EPA and NOAA. The submittal does not provide information or analysis to support the position that lakes that are flushed less than 50 times per year will not adversely affect downstream waters. Further, while Maine suggests that pollutant attenuation may alter the impact of any upstream pollutants on Maine's coastal waters, the submittal does not include data to indicate the extent to which such attenuation occurs in its waters and acknowledges that it is not known how far along Maine's rivers pollutants must travel before becoming fully attenuated. II. AGRICULTURE FINDING: Maine's program includes management measures in conformity with the 6217(g) guidance, except for the measures for confined animal facilities. Maine has identified back-up enforceable authorities but has not demonstrated the ability of the authorities to ensure implementation throughout the 6217 management area. Maine has provided sufficient justification for an exclusion of irrigated agricultural lands from the irrigation management measure. CONDITIONS: Within one year, Maine will include in its program management measures for confined animal facilities in conformity with the 6217(g) guidance. Within one year, the State will develop a strategy (in accordance with Section XIV, page 18) to implement the agricultural management measures throughout the 6217 management area. RATIONALE: Maine has proposed to implement the section 6217(g) management measures, with the exception of the irrigation management measure, using existing programs and authorities. Practices are specified for manure management in Maine's "Strategy for Managing Nonpoint Source Pollution from Agricultural Sources and Best Management System Guidelines." However, the practices for collection, storage, and treatment of facility wastewater and runoff from confined animal facilities are set forth too generally to inform the reader or user how they are to be used to achieve the management measure. For example, Maine's guidelines do not specify that systems should have sufficient storage capacity to handle a 25-year, 24-hour storm, as called for by the measure for large facilities. In addition, the State expresses concern regarding the technical feasibility of storing animal waste and runoff over winter at some sites, suggesting that it will in those cases apply to larger facilities the less stringent measure designed for small facilities. Finally, NOAA and EPA suggest that Maine should include in its program a list of practices, including their standards and specifications, that it will implement to achieve the management measures for confined animal facilities. Existing programs for agriculture in Maine are largely voluntary, but the State has specific authority to control the distribution and application of limited and restricted use pesticides under its Pesticide Control Act (7 MRSA Section 601 et seq) and has guidelines (minimum requirements for municipal shoreland ordinances, which are mandatory) for tilling, manure spreading, storage and disposal, and grazing under the Mandatory Shoreland Zoning Law (38 MRSA 435 et seq). Cases involving improper use of pesticides can be referred to the Board of Pesticide Control. The State has also identified its Nuisance Law (17 MRSA  2701 et seq) and its Waste Discharge Law (38 MRSA 411 et seq) as back-up enforceable policies and mechanisms. Maine has a two tier approach to enforcement. The first tier is a complaint-response system under which all complaints regarding agriculture are received and investigated by the Department of Agriculture, Food and Rural Resources (DAFRR). DAFRR recommends site-specific BMPs to address water quality concerns, and farmers who implement the BMPs are protected from nuisance liability. If a farmer does not comply with the BMPs, the case can be referred to the Department of Environmental Protection (DEP) or the Attorney General for the second tier of enforcement. DEP has a back-up authority to enforce BMPs under the Waste Discharge Law, which prohibits the discharge of any pollutant into waters of the State. An exemption for agricultural erosion is granted to farmers who prepare an erosion and sediment control plan approved by the DEP. Under DEP rules (06-096 CMR 516), these erosion and sediment control plans address erosion control, proper animal waste management, and fertilizer management. However, the State reports that only 1 farm in the State has an approved plan, despite the fact that the rules became effective in 1981. In addition, enforcement actions cannot be taken if there are no federal or State funds available to the farmer to cover at least half the cost of implementing the plan. In developing its implementation strategy, Maine should the feasibility of increasing the number of approved erosion and sedimentation plans to ensure that the applicable management measures are addressed. The Attorney General can require BMPs as a civil remedy in a nuisance lawsuit under the Nuisance Law. The site-specific practices prescribed by the DAFRR under the Nuisance Law are key to compliance with the management measures under that program, but the State has not identified which BMPs will be used, providing only that USDA technical guides will be applied. Maine is encouraged to describe in its implementation strategy how site- specific remedies will be used to ensure implementation of all applicable management measures on farms under the Nuisance Law. A key aspect of Maine's approach is the State's intent to use existing authorities to implement the management measures in priority watersheds identified by DEP. The State should describe in its strategy the criteria that will be used to identify priority areas, and a schedule showing when implementation will occur throughout the 6217 management area. Maine reports that only 2.6% of cropland is irrigated in Maine. Within the proposed 6217 management area, the percentage is 2.0%. The average acreage irrigated per farm is 11 acres. While the use of irrigation in Maine is currently limited, NOAA and EPA believe that agricultural irrigation can be an issue of potential concern in specific coastal watersheds in Maine. This concern can arise where the increased use of irrigation results in increased pesticide and nutrient loadings and significant decreases in stream flows that may negatively impact coastal waters. We applaud Maine's efforts under the Governor's Atlantic Salmon Task Force and appreciate the State's support of EPA New England's Low Flow Initiative. NOAA and EPA encourage the State to monitor the growing use of agricultural irrigation in Maine. If expansion of this activity occurs so that it may impact coastal waters, the exclusion of irrigation from the State's coastal nonpoint program should be reconsidered. III. FORESTRY FINDING: Maine has not provided justification to support a categorical exclusion of forestry from its coastal nonpoint program. CONDITION: Within three years, Maine will include in its program management measures in conformity with the 6217 (g) guidance and enforceable policies and mechanisms to ensure implementation of the forestry management measures throughout the 6217 management area. RATIONALE: Forestry is a major land use in Maine, including in the coastal watersheds. Over 90% of forested land in Maine is in private ownership. Timber harvesting is increasing somewhat statewide, however, there is a trend toward more selective cutting. Most harvesting operations occur on parcels of 5,000 acres or more; approximately 25% occur on parcels of 100 or less acres. In its Section 305(b) reports, estuary profile series, and 319 nonpoint source assessment, Maine has identified at least seven waterbodies within its coastal boundary that are impaired by forestry activities. These include six lakes and ponds located in river basins that enter tidewater (Nash Lake, Damariscotta Lake, Nequasset Pond, Bottle Lake, Keg Lake, and Lombard Lake), which total 6084 acres. In addition, at least three estuaries (St. George River Estuary, Machias River Estuary, and Dennys River Estuary) and the North Perry/Cutler Harbor have been reported as threatened by forestry activities. Impacts include organic enrichment, dissolved oxygen, temperature, nutrients, and herbicides. Within the larger 6217 management area recommended by NOAA, Maine has identified 26,240 acres of State lakes that are impaired by forestry. The State's Forest Practices Act provides a sound basis for the implementation of the management measures throughout the 6217 management area. NOAA and EPA wish to engage in a cooperative process with the State to determine an appropriate means to address forestry operations in Maine's Section 6217 program. IV. URBAN A. NEW DEVELOPMENT FINDING: Maine has submitted an alternative management measure to meet the new development management measure, but has not demonstrated that the alternative measure is as effective as the management measure in the 6217 (g) guidance. The State has identified enforceable policies and mechanisms to ensure implementation of the alternative management measure in a portion of the 6217 management area, and has identified a backup enforceable authority for remaining areas, but has not demonstrated the ability of the latter authority to ensure implementation throughout the 6217 management area. The State has provided justification for exclusion of the unorganized territories from the general application of the new development management measure. CONDITION: Within three years, the State of Maine will demonstrate that the alternative management measure for new development is as effective as the measure set forth in the (g) guidance, or will include in its program management measures for new development in conformity with the (g) guidance. Within one year, the State will develop a strategy (in accordance with Section XIV, page 18) to implement the new development management measure throughout the 6217 management area. RATIONALE: Under the Mandatory Shoreland Zoning Act , new development and construction in the shoreland zone (38 MRSA section 435) in municipalities is designed to minimize stormwater runoff in excess of natural predevelopment conditions. Under the Site Location of Development Law (38 MRSA  481 et seq.), a State permit is required for a range of activities, including projects involving construction of a structure that occupies an area greater than three acres. Per the State, the jurisdiction under the Site Location of Development law extends to unorganized territories but often is not exercised in these areas. Permits under the existing Site Location of Development Law require, under DEP rules, an approved storm water management plan with a storm water management system that must infiltrate, detain or retain the peak runoff flow of a 25-year, 24-hour storm at pre-development levels. Recently, the State adopted the 1996 Site Law Reform (effective July 1997), which requires stormwater management for sites exceeding 20,000 square feet of impervious area or 5 acres or more of disturbed area in the direct watershed of a water body most at risk from new development or one acre or more of impervious area or five or more acres of disturbed area in a sensitive or threatened geographic region or watershed (areas, established by rule, e.g., that provide public water supplies or have documented pollution problems). The permit would provide approval of runoff control measures for stormwater management. Towns with the capacity to review stormwater permits would be exempt from the 1996 Site Law Reform, but in cases where municipalities are not able to do so, or for projects of a State or Regional significance, the State would retain review of projects. The State has identified the Water Pollution Control Law (38 MRSA  411 et seq), also known as the Waste Discharge Law, which requires a license from DEP for any direct or indirect discharge of any pollutant, as a backup enforceable policy and mechanism for projects and areas not covered under the jurisdiction of the above authorities. In implementing this management measure, the State proposes an alternative approach through its new Stormwater Rules that has different requirements, depending on the size and location of the development. The rules identify places where the requirements apply and the standards to be met. In general, projects in lake watersheds "most at risk" from development must control stormwater quantity and quality, meeting either a phosphorus allocation standard or an 80% TSS removal standard. Projects in other lake watersheds must use a prescribed set of soil stabilization methods. In coastal watersheds "most at risk," projects must control stormwater quality to meet a sliding scale TSS removal standard based on the amount of new impervious area created. The maximum removal rate requirement of 80% would apply only to 100% impervious sites. However, Maine has not demonstrated that this approach will be as effective in controlling runoff as the (g) management measure. The State has proposed excluding the New Development, Watershed Protection, Site Development, Construction Site Erosion and Sediment Control, Construction Site Chemical Control, Existing Development, and Roads, Highways and Bridges management measures from application to the unorganized territories. The State bases its proposal on the sparse population in the coastal unorganized territories (1990 population of 2,088 - an increase of 400 people since 1970) and associated limited growth (114 new or converted homes between 1980 and 1990). While seasonal home development is projected to increase in the 1990's (2600 - 3000 homes), only 6% of this increase is projected in the coastal areas. Under the Natural Resources Protection Act (38 MRSA 480-A et seq.), most land disturbing activities in or adjacent to (within 100 feet of) protected natural resources, including coastal wetlands and sand dunes, must receive a permit from the DEP. In order to receive a permit, the proposed activity must not, among other considerations, violate a state water quality standard. Under the Land Use Regulation in Unorganized Territories (12 MRSA 681 et seq.), the Land Use Regulation Commission established Shoreland Protection Districts defined, in part, as an area extending 250 feet from tidal waters. Within these districts, permitted land uses require a permit from the Commission and must meet Commission standards. The combination of these existing authorities allow the State to manage development in the unorganized territories likely to have a significant impact on coastal waters. B. WATERSHED PROTECTION AND EXISTING DEVELOPMENT FINDING: Maine's program includes management measures in conformity with the 6217(g) guidance except that the program does not include provisions to ensure that development is sited to protect water bodies and natural drainage systems for the watershed protection management measure and does not address elements #1 and #2 of the existing development management measure. Maine's program includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. The State has provided sufficient justification for exclusion of the unorganized territories from the general application of the watershed protection and existing development management measures. CONDITION: Within two years, Maine will include in its program management measures in conformity with the 6217(g) guidance for the watershed protection management measure to ensure that development is sited to protect water bodies and natural drainage systems, and to address elements #1 and #2 of the existing development management measure with the exception of those excluded areas of the unorganized territories. (See discussion under the New Development management measure.) RATIONALE: The program submittal describes several programs in Maine that together may be used to implement these management measures. These include the Natural Resources Protection Act, the Mandatory Shoreland Zoning Law, the Site Location of Development Law, the Growth Management Program (30-A MRSA  4311 et seq), the Erosion and Sedimentation Control Law (38 MRSA sec. 420-C), and the Nonpoint Source Pollution Program (38 MRSA 410-H et seq.). The Natural Resources Protection Act (38 MRSA  480-A et seq.) directs development away from protected resources (including coastal and freshwater wetlands, significant wildlife habitat, great ponds or rivers, and streams or brooks), and imposes standards on activity in or adjacent to these resources in the form of permits. For some activities, the regulations implementing the Natural Resources Protection Act use a "permit-by rule" (general permit) approach which states that BMPs should be followed to meet the standards (06-096 CMR 305). The Mandatory Shoreland Zoning Law requires municipalities to protect shoreland areas. The Site Location of Development Law permits apply to sites greater than 3 acres outside the shoreland zone. For sites falling below the Site Location of Development Law cut-off and located outside the Mandatory Shoreland Zoning area, the watershed management measure may be, but is currently not required to be, implemented by those municipalities that choose to rely on the Growth Management Program. A goal of the Growth Management Program is to implement watershed management by municipal natural resources inventories and implementation plans with regional and municipal coordination. The 1996 Site Law Reform expands implementation of these measures, yet alone does not ensure implementation of the full watershed protection management measure throughout the 6217 management area. The program submittal mentions State and regional efforts related to watershed planning including the Damariscotta River and Sebago Lake watershed. NOAA and EPA support these efforts, but based on the limited information in the program submittal, cannot conclude that these efforts represent a watershed protection program that will provide the framework throughout the 6217 management area to ensure that development is sited so as to protect waterbodies and natural drainage systems. NOAA and EPA encourage the State to continue these efforts and to use experience from these projects to further develop practices that will implement all of the elements of the management measure for watershed protection. The Nonpoint Source Pollution Program (38 MRSA  410-I et seq.) provides a mechanism for State agencies to cooperate in identifying priority watersheds for preventing or reducing pollution generated by nonpoint sources. In addition, Maine's submittal includes proposed activities, including completion of a retrofit priority project which was scheduled to begin in 1995 and which, if completed, could address elements #1 and #2 of the existing development management measures. C. SITE DEVELOPMENT, CONSTRUCTION SITE EROSION AND SEDIMENT CONTROL, and CONSTRUCTION SITE CHEMICAL CONTROL FINDING: Maine's program includes management measures in conformity with the 6217(g) guidance, except the program does not include management measures for construction site chemical control. The State has identified enforceable policies and mechanisms to ensure implementation in a portion of the 6217 management area, and has identified a backup enforceable authority for remaining areas but has not demonstrated the ability of the authority to ensure implementation throughout the 6217 management area. The State has provided sufficient justification for exclusion of the unorganized territories from the general application of the site development, construction site erosion and sediment control, and construction site chemical control management measures. (See discussion under the New Development management measure.) CONDITION: Within two years, the State will include in its program management measures for construction site chemical control in conformity with the 6217 (g) guidance. Within one year, the State will develop a strategy (in accordance with Section XIV, page 18) to implement the site development, construction site erosion and sediment control, and construction site chemical control measures throughout the 6217 management area with the exception of those excluded areas of the unorganized territories. RATIONALE: Maine's program addresses the components of the site development management measure. The Natural Resources Protection Act directs development away from protected resources, and imposes standards on activity in or adjacent to those resources in the form of permits. Under the Mandatory Shoreland Zoning Act, development in the shoreland zone in municipalities must limit land disturbance, protect natural drainage features, and be sited so as to avoid severe erosion, improper drainage, and water pollution. Larger development subject to the Site Location of Development Law must take measures to prevent unreasonable alteration of natural drainage ways, and avoid unsuitable soil types and steep slopes. The Maine Erosion and Sediment Control Handbook for Construction: Best Management Practices contains practices in conformity with the construction site erosion and sediment control management measure. The NRPA permit application requires identification of erosion control measures in conformity with the erosion and sediment control manual. Erosion and sediment control plans are also required for development pursuant to the Mandatory Shoreline Zoning Act and the Site Location of Development Law. The Natural Resources Protection Act provides authority to require nutrient and chemical handling standards, as well as specify fertilizer application rates, within areas adjacent to protected resources. In addition, Maine has the ability to ensure that the pesticide aspects of the measure are implemented through the State Pesticide Control Laws (22 MRSA  1471-a et seq.; 7MRSA 601 et seq.). Action can also be taken in cases where a water quality standard, under the Water Pollution Control Law, has been violated due to discharge or spill of mercury or toxic or hazardous substances. However, these various authorities do not provide for specific practices in conformity with the construction site chemical control measures to be uniformly applied to construction projects throughout the 6217 management area. NOAA and EPA suggest that the State consider a revision to the Maine Erosion and Sediment Control Handbook for Construction: Best Management Practices to include construction site chemical management practices as a vehicle to promote consistent application of the construction site chemical control measure. For development not under the jurisdiction of the laws discussed above, the State has identified the Water Pollution Control Law (38 MRSA  413(1)) as a backup enforceable authority, but has not demonstrated the ability of the authority to ensure implementation throughout the 6217 management area. D. NEW and OPERATING DISPOSAL SYSTEMS (OSDS) FINDING: Maine's program includes management measures in conformity with the 6217(g) guidance, except it does not provide for (1) establishment of adequate protective separation distances between OSDS and ground water for new OSDS; (2) a program to inspect existing OSDS at a frequency to ascertain whether they are failing; and, (3) denitrifying systems where nitrogen limited surface waters may be adversely affected by excess nitrogen loadings from OSDS. Maine includes enforceable policies and mechanisms to ensure implementation of the management measures. CONDITION: Within two years, Maine will include in its program management measures in conformity with the (g) guidance to provide for (1) establishment of adequate protective separation distances between OSDS and ground water for new OSDS; (2) a program for the inspection of operating OSDS; and, (3) denitrifying systems where nitrogen limited surface waters may be adversely affected by excess nitrogen loadings from OSDS. RATIONALE: Maine has a comprehensive regulatory program for OSDS, including the Subsurface Waste Water Disposal Rules (30-A MRSA  4201 et seq.) and the Water Pollution Control Law (38 MRSA 413(1)). Existing regulations require permits to install or convert any OSDS. Notification and/or inspection requirements for new OSDS provide a mechanism to ensure that OSDS are sited and installed to minimize impacts. Existing regulations require a minimum of at least a twelve to twenty-four inch separation distance between OSDS and ground water. In evaluating sites for separation distances, the State's methodology identifies temporary, perched water tables, not apparent water tables. In addition, the Subsurface Waste Water Disposal rules require a liner for systems in the coarsest soils to further treat and slow effluent movement to the water table. In determining that the State's separation distance requirements do not meet the management measure, EPA and NOAA considered the supplemental information provided by the State and found that the information was not adequate to support the State's position that its separation distance requirements and associated policies adequately protect coastal waters. In a recent report, The Quality of Maine's Waters, Maine identified bacteria, coming mostly from failing septic systems and overboard discharges, as a significant cause of non-attainment of uses for marine and estuarine waters. Inadequate separation distance requirements may be a major factor influencing these septic system failures. Additional information is needed to support the adequacy of the State's separation distance requirements. This information could include: soil maps; information on seasonal high water table depths; demographic data; nitrogen and pathogen loading studies; locations and causes (if known) of failing septic systems; water quality assessments; information on shellfish bed closures; clarification of siting criteria, policies and procedures; and other reports or studies documenting the adequacy of the State's current separation distance requirements. The State lacks requirements for the periodic inspection of operating OSDS and does not address the protection of nitrogen- limited waters. The State is encouraged to expand the Subsurface Waste Water Disposal Rules, which currently include a model ordinance to encourage municipalities to develop inspection requirements when necessary, into a program that is in conformity with the 6217(g) management measures. E. POLLUTION PREVENTION FINDING: Maine's program includes management measures in conformity with the 6217(g) guidance. RATIONALE: Maine's program submittal describes a number of existing efforts, including efforts by the Nonpoint Source Pollution Program (38 MRSA 410-H et seq.), the Maine Pollution Prevention Program and the DEP Pollution Prevention Division which address this management measure. The State provided a list of publications and outreach activities that address the specific components of the management measure. NOAA and EPA encourage the State to include household hazardous waste, yard maintenance and other individual activities in its public education efforts. F. ROADS, HIGHWAYS, AND BRIDGES FINDING: Maine's program includes management measures for roads, highways, and bridges in conformity with the 6217(g) guidance except for the runoff systems management measure. Maine's program includes enforceable policies and mechanisms to ensure implementation of the management measures. The State has provided sufficient justification for the exclusion of the unorganized territories from the general application of the roads, highways and bridges management measures. (See discussion under the New Development management measure.) CONDITION: Within three years, Maine will include roads, highways and bridges in schedules developed under its urban storm water retrofit program. RATIONALE: Maine implements a program that meets the planning, siting, and design management measures through prohibition of roads in unusual natural areas, areas of particular importance to fish and wildlife, Resource Protection Districts established under the Mandatory Shoreland Zoning Act, and along significant river segments. Maine's program also includes standards for setbacks from water bodies, vegetative buffer requirements, limits on clearing and grading, mandatory shoreline zoning, and environmental reviews by Maine's Department of Transportation (DOT) for State roads, highways, and bridges and the Department of Environmental Protection (DEP) under the Site law for local road construction. Private roads exempt from reviews must still meet DEP standards for protection of environmental resources. The construction site erosion and sediment control measure is met by erosion and sediment control plans, preconstruction conferences, and BMP Guidance Manuals for both roads, highways and bridges and general construction. The State also provides highway maintenance manuals and education and technical assistance to conform to the operation and maintenance measure. Special practices apply to cleaning and painting steel and bridge maintenance. Maine has also developed standard specifications to require a Spill Prevention, Containment, and Countermeasure Plan at roads, highways and bridge construction sites to meet the management measure for construction site chemical control. The State plans to meet the runoff systems measure by including roads, highways and bridges in its urban stormwater retrofit program. Maine has enforceable policies and mechanisms to ensure implementation of the measures. The NRPA and Site Location of Development Law require reviews, permits, erosion and sediment controls, and protection of water bodies. The Mandatory Shoreline Zoning Act requires municipal zoning ordinances to protect shoreland areas from flooding and limits clearing of shoreline vegetation. V. MARINAS AND RECREATIONAL BOATING FINDING: Maine's program includes management measures in conformity with the 6217(g) guidance, except for the storm water management measure. The program includes enforceable policies and mechanisms to ensure implementation of the siting and design management measures and the boat operation management measure. The State has identified a backup enforceable authority to address the solid waste management, fish waste, liquid material, petroleum control, boat cleaning, and sewage facility management measures, but has not demonstrated the ability of the authority to ensure implementation throughout the 6217 management area. Maine has provided justification to exclude the unorganized territories of the State from application of the marinas and recreational boating management measures. CONDITION: Within two years, the State will include in its program management measures for storm water management in conformity with the (g) guidance. Within one year, the State will develop a strategy (in accordance with Section XIV, page 18) to implement the solid waste management, fish waste, liquid material, petroleum control, boat cleaning, and sewage facility management measures throughout the 6217 management area. RATIONALE: Marinas and boat yards in Maine are governed by a number of laws and regulations that can be used to implement the management measures. With regard to siting and design, permits are required for the construction of new and expanding marinas under the Natural Resources Protection Act and Site Location of Development Law. New, expanding, and existing marinas are also subject to the Mandatory Shoreland Zoning Act, Oil Discharge Prevention and Pollution Control Law (38 MRSA 541), and the Watercraft Sewage Pumpout Law (38 MRSA 423-B). The State has included in its program submission several suggestions that could significantly improve management for siting and design of new and expanding marinas. NOAA and EPA encourage the State to include the Marina Advisory Group's recommendations for an addendum to the NRPA permit application for new and expanding marinas to require information on tides, depths, flows, and water quality, and to expand the use of shellfish and other habitat mapping on GIS in conjunction with the permitting process. The State addresses the boat operation management measure through the requirement that boasters operate at no greater than headway speed within 200 feet of mainland or islands. In addition, the Commissioner of Inland Fish & Wildlife may designate off- limits areas when necessary for wildlife protection (12 M.R.S.A. sec.7791). The State recently published a manual entitled Controlling Nonpoint Pollution in Maine, an Environmental Guide for Marinas & Boatyards. The manual contains practices that are in conformity with the 6217 (g) guidance. The State has identified the Water Pollution Control Law (38 MRSA  411 et. seq.) as a backup enforceable policy and mechanism that can be used to address discharge of pollutants to coastal waters from activities associated with the operation and maintenance of marinas. However, the State has not demonstrated the ability of this authority to ensure implementation of the measures throughout the 6217 management area. The State also notes that permitting of new and expanding marinas under the NRPA and the Site Law could be used to ensure implementation of the management measures. However, there is currently no tie between the practices identified in the marina manual and the criteria used for permitting these facilities. NOAA and EPA encourage the State to clearly tie the newly developed BMP manual on marinas to the permitting authorities discussed above in order to ensure consistent and predictable application of the best management practices. The State's submittal states that there are currently no marinas or boatyards in the unorganized coastal areas, which consists of two coastal townships and several islands. No new marinas or boatyards are expected in these areas in the foreseeable future. Therefore, there is not a need to apply the marina and recreational boating management measures to the unorganized areas of the State. VI. HYDROMODIFICATION FINDINGS: Maine's program includes management measures in conformity with the 6217(g) guidance, except for the element of the chemical and pollutant control management measure requiring limiting the application, generation and migration of toxic substances. Maine's program also includes enforceable policies and mechanisms to ensure implementation of the hydromodification management measures, except for the above mentioned element of the chemical and pollutant control management measure and for erosion and sediment control at dams. For the erosion and sediment control management measure, the State has identified enforceable authorities, but has not demonstrated the ability of the authorities to ensure implementation of the management measure throughout the 6217 management area. CONDITIONS: Within two years, Maine will include in its program management measures and enforceable policies and mechanisms to implement the element of the chemical and pollutant control management measure requiring limiting the application, generation and migration of toxic substances. Within two years, Maine will also demonstrate its ability to achieve implementation of the management measure for erosion and sediment control at dams using the approach described in the State's submittal, coupled with the Natural Resources Protection Act, the Waterway Development and Conservation Act, and the Site Location of Development Law. RATIONALE: Under the Natural Resources Protection Act (NRPA), Maine requires permits for new channelization activities in rivers, streams, lakes, and coastal waters. Projects are evaluated for effects on natural flows, water quality, flooding, and habitat. Problems caused by existing channelization are identified by State agencies and/or watershed surveys, and are resolved on a case-by- case basis through enforcement and modifications to permits. In some cases, the Waste Discharge law may be used to stop the discharge of pollutants from existing projects. Maine has identified the NRPA and the Waterway Development and Conservation Act (WDCA) (38 MRSA 630 et seq.) as enforceable authorities to implement the management measure for erosion and sediment control at dams. These laws, however, do not provide for erosion and sediment control plans to be developed for activities related to the construction and/or maintenance of dams. Furthermore, the WDCA specifically exempts many soil disturbance activities associated with normal maintenance and repair of operating hydropower dams. The Site Location of Development Law requires new dams to meet standards for erosion and sediment control, but existing dams authorized prior to May 9, 1970 are exempt. In addition, the erosion control law (38 MRSA sec. 420-C) applies only to land disturbing activities within the organized areas of the State. The second condition above fills this gap. Maine implements the management measure for chemical and pollutant control at dams through controls on the storage, handling, and disposal of hazardous waste; but the state does not limit the application of toxic materials at dam construction sites. To fully implement this management measure, the state intends to add a requirement for chemical spill prevention and containment plans to existing permitting authorities. State permits also specify fertilizer application rates to control erosion. Maine implements the management measure for protection of surface water quality and habitat from the effects of dam operation by enforcing and/or modifying permits for dams. The Waste Discharge Law, which prohibits discharges of pollutants into Maine waters, can also be used to enforce this management measure. Finally, the State Planning Office is charged with creating a management plan for every river that has a FERC- licensed hydropower dam. Maine further applies these mechanisms to solve nonpoint source problems associated with excessive surface water withdrawals. Maine implements management measures for shoreline and streambank erosion by requiring permits for shoreline and streambank stabilization activities. Erosion of shorelines or streambanks causing a nonpoint source problem is identified by State agencies and/or watershed surveys, and the Waste Discharge Law can be used if necessary to implement a solution to erosion causing a water quality problem. Shorelines or streambank features with the potential to reduce nonpoint source pollution are protected from the effects of new activities by the NRPA, which stipulates no unreasonable harm to significant wildlife habitat from permitted activities. Streambanks and shorelines are also protected under the Mandatory Shoreland Zoning Act, which imposes municipal land-use controls within 250 feet of nonforested wetlands. VII. WETLANDS, RIPARIAN AREAS AND VEGETATED TREATMENT SYSTEMS FINDING: Maine'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. However, the program does not apply management measures to projects other than new work proposed within wetlands. CONDITION: Within two years, Maine will develop a process to apply management measures to problems in wetland and riparian areas that are not currently reviewed under existing permit authorities. RATIONALE: Maine protects wetlands and riparian areas through the Natural Resources Protection Act, and the Mandatory Shoreland Zoning Act. These laws require permits for activities involving dredge or fill in wetlands, and municipal zoning and land-use controls within 250 feet of nonforested wetlands. For freshwater wetlands, permits are required for wetlands containing at least 20,000 square feet of aquatic vegetation, emergent vegetation or open water. Maine's program to protect wetlands and riparian areas with significant nonpoint source functions applies management measures only to new projects within regulated areas. The program does not protect nonpoint source functions either from existing conditions within wetlands and riparian areas, or from activities upstream in the watershed which can affect the nonpoint source functions in wetlands and riparian areas. Maine implements the management measure promoting restoration of wetlands and riparian areas through the compensation requirements of the State's Wetland Protection Rules (06-096 CMR 310). A work group of the State Wetlands Task Force is exploring ways to target degraded wetlands serving important functions for restoration as a part of mitigation activities, and to add these sites as priorities for restoration as part of the State's Wetlands Conservation Plan. Maine implements the management measure to promote vegetated treatment systems through the review of permits for alterations in wetlands and along shorelines. Vegetated treatment systems are also required as needed to control stormwater discharges for larger construction projects. VIII. ADMINISTRATIVE COORDINATION FINDING: Maine's program establishes mechanisms to improve coordination among State agencies and between State and local officials. RATIONALE: Maine proposes to implement the coastal nonpoint program through a combination of several State and local authorities administered by agencies described in the State's program submittal. Many of the programs that will be used to implement the State's coastal nonpoint program are housed within the Maine DEP, which is responsible for administering most of the State's core authorities for the coastal management and other resource management programs. In addition, the State relies on a Nonpoint Source Advisory Group that consists of various State agencies and other interests concerned with water quality issues. Finally, the Land and Water Resources Council (LWRC), composed of commissioners of State agencies concerned with the use and protection of natural resources, provides a mechanism for policy coordination among State agencies. IX. PUBLIC PARTICIPATION FINDING: Maine's program provides opportunities for public participation in the development and implementation of its coastal nonpoint program. RATIONALE: The State's submittal describes several activities that provide opportunities for public participation in the development and implementation of its coastal nonpoint program. These include the continued use of special work groups for each Section 6217 source category, and publication of a quarterly newsletter, the NPS Times, which will be used to educate and inform the public about various nonpoint source issues and opportunities for further participation in the program. Comments solicited and received on the effectiveness of the State's coastal nonpoint program will be used to evaluate and improve opportunities by the public to participate in the State's program. Maine provided a 30-day public comment period on the final program submittal and responded to the comments on the submittal. X. TECHNICAL ASSISTANCE FINDING: Maine has included programs that will provide technical assistance to local governments and the public for implementing additional management measures. RATIONALE: Maine plans a variety of technical assistance efforts for local governments and the public. These efforts will emphasize several issues relative to nonpoint source pollution activities. Technical assistance will be conducted by a variety of sources including State agencies such as the Maine Coastal Zone Management Program (MCZMP), Maine DEP and Department of Agriculture, Food and Rural Resources (DAFRR); and Federal agencies such as the Natural Resources Conservation Service in concert with DAFRR. The assistance will include traditional State agency technical assistance such as the preparation of guidance documents and other manuals, training workshops and seminars, one-on-one assistance by the State technical assistance staff, and financial assistance programs such as the MCZMP and EPA's Section 319 program. XI. ADDITIONAL MANAGEMENT MEASURES FINDING: Maine's program provides for implementation and continuing revision of additional management measures applicable to critical coastal areas and cases where 6217 (g) management measures are fully implemented but water quality threats or impairments persist. RATIONALE: To deal with impaired coastal waters that require additional management measures, the State will conduct a waste load allocation for the pollutant(s) of concern in the watershed of the impaired coastal water. If it is determined that additional management measures are needed to attain the target load of the pollutant, appropriate measures will be developed and implemented based on the recommendations from the NPS Advisory Group for each nonpoint source category implicated in the particular watershed. The State's process is further described in section V of the program submittal. XII. CRITICAL COASTAL AREAS FINDING: Maine's program identifies and includes a process for the continuing identification of critical coastal areas adjacent to impaired and threatened coastal waters. RATIONALE: Maine's program submittal identifies several priority areas that require a critical coastal area designation. These include Fore River, Boothbay Harbor and closed shellfish harvesting areas impacted by nonpoint source pollution. Initially, the State proposes to designate the land area in the watershed below lake outlets as the critical coastal areas for these coastal waters. These areas and the priority watersheds that will be identified as part of the State's overall watershed assessment efforts generally follow the second approach described in the program guidance whereby the State relies on site-specific evaluations to determine the extent of the critical coastal areas. Maps of the critical areas will be prepared once the analyses are completed. XIII. MONITORING FINDING: Maine does not include in its program a plan to assess over time the success of the management measures in reducing pollution loads and improving water quality. CONDITION: Within one year, Maine will include in its program a plan that enables the State to assess over time the extent to which implementation of management measures is reducing pollution loads and improving water quality. RATIONALE: Maine proposes several monitoring efforts that it will carry out under its coastal nonpoint program. It appears that Maine could use these efforts to assess over time the success of the management measures in reducing pollution loads and improving water quality if the monitoring is better linked to the 6217 management measures. For example, Maine's compliance monitoring efforts for agriculture, forestry, urban sources, marinas, hydromodification, and wetlands are keyed to best management practices (BMPs) but not to management measures. The State should be able to tweak these efforts slightly to track management measures as well as individual BMPs. The investigation of nutrient-induced hypoxia and the ambient toxics and pathogen monitoring programs appear to provide opportunities to assess the impacts of selected management measures on water quality, sediment, or seafood tissue. Maine should try to track management measure implementation in a few areas where such data can be combined with the monitoring data to assess the success of management measures in improving water quality. Maine also proposes that a watershed monitoring project will be developed to determine the effect of BMPs on water quality. Maine should consider designing this monitoring project to determine the effects of selected management measures on water quality. Maine should include in its plan information regarding the number and location of monitoring stations, the types and frequency of water quality data being collected, methods for tracking management measure implementation, 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. XIV. STRATEGY AND EVALUATION OF BACKUP AUTHORITIES Within one year, Maine will develop a strategy to implement the management measures for agriculture, urban (new development, site development, erosion and sediment control, and construction site chemical control) and marina operation and maintenance 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, Maine will also develop and apply credible survey tools to demonstrate the ability of the State's approach to achieve implementation of 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.
