FINDINGS FOR THE MICHIGAN COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the State of Michigan pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the Michigan Coastal Nonpoint Source Program, Final Document, June 1995 and supplemental material provided by Michigan 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 Michigan 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 Michigan 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 Michigan's program. It also provides the rationale for the findings and includes conditions that will need to be met for Michigan to receive final approval of its program. We recognize that Michigan has already proposed some 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. 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 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 Michigan Coastal Nonpoint Source Program, Final Document, June 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 Michigan 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: Robert Goo (202/260-7025) NOAA/Office of Ocean and Coastal Resource Management Coastal Programs Division SSMC-4, N/ORM3 1305 East-West Highway Silver Spring, MD 20910 Contact: Kenneth Walker (301/713-3113, x169) U.S. EPA Office of Watersheds & Nonpoint Source Programs Water Division 77 West Jackson Street Chicago, IL 60604 Contact: Tom Davenport (312/886-0209) I. BOUNDARY FINDING: Michigan's proposed boundary for the 6217 management area, as shown in Figure C of the program submittal, is sufficient to control the land and water uses that have or are reasonably expected to have a significant impact on Michigan's coastal waters. RATIONALE: Michigan's proposed boundary approximates the NOAA recommendation of coastal watersheds, with the exception of the Southwestern Lower Peninsula (Cass, St. Joseph, and Kalamazoo counties), the Northern Lower Peninsula (Emmet, Cheboygan, Alpena, Alcona, Oscoda, Otsego, Wexford, Kalkaska and Crawford counties) and the Northwest Upper Peninsula (Marquette, Dickinson, Ontonagon, and Luce counties). Michigan's refinement of the NOAA recommendation in these watersheds is based on the premise that dams in the lower reaches of these drainage basins effectively serve to trap nonpoint source pollutants before they reach the coastal waters of Michigan. As described in the program submittal, dams that define the upstream limit of the management area are included in the management area and are subject to the 6217(g) management measures for dams. While the data supporting the State's premise is limited to a single pilot study of the Muskegon River watershed, NOAA and EPA do not have information to indicate that the State proposal excludes (a) existing land or water uses that reasonably can be expected to have a significant impact on the coastal waters of the State, or (b) reasonably foreseeable threats to coastal waters from nearby activities landward of the State's 6217 management area. Michigan also provided supplemental information on detention times for several dams in close proximity to coastal waters. NOAA and EPA have concerns that the detention time of 12 hours for the Escanaba dams may not be extensive enough to effectively remove nonpoint pollutants. We recommend that Michigan monitor the Marquette watershed (above the Escanaba dams) for land use changes and make any appropriate changes to the management area based on that data. II. AGRICULTURE FINDING: Michigan's program includes management measures in conformity with the 6217(g) guidance. The State has identified back-up enforceable policies and mechanisms to implement the agricultural management measures, but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within one year, Michigan will develop a strategy (in accordance with Section XIV, page 16) to implement the agricultural management measures throughout the 6217 management area. RATIONALE: As described in the program submittal, Michigan proposes to implement the 6217(g) agricultural management measures through guidance on Generally Accepted Agricultural and Management Practices (GAAMPs). The GAAMPs currently address management measures for facility wastewater and runoff from confined animal facilities, grazing, and irrigation water management. Subsequent to the program submittal, Michigan provided additional technical guidance that is used to implement the agricultural management measures. The State's Agricultural Best Management Practices (BMP) Manual for Michigan's Nonpoint Source Control Program includes practices that can be used to implement the erosion and sediment control, nutrient and pesticide management measures. According to supplemental material provided by Michigan, this manual is used by technical staff of state and Federal agencies, as well as soil and water conservation districts, to promote water quality protection practices. The practices in the manual for erosion and sediment control, nutrient and pest management are in conformity with the 6217(g) guidance, while the GAAMPs do not fully address these management measures. Since Michigan's program submittal focused on the GAAMPs, it is important that the practices in the Agricultural BMP Manual for erosion and sediment control, nutrient and pest management be used (instead of the GAAMPs) as the basis for implementing the coastal nonpoint program. Michigan is currently developing GAAMPs for erosion and sediment control, which could further support implementation of the erosion and sediment control management measure. Michigan statutes provide incentives to implement GAAMPs. For example, farmers who implement GAAMPs are exempt from liability for common law nuisance under the Right to Farm Act (1981 PA 93, as amended) and from liability for hazardous waste cleanup under the Environmental Response Act (1982 PA 307). However, these authorities do not specifically require farmers to implement GAAMPs. Michigan has identified a back-up enforceable policy and mechanism, the Water Resources Commission Act, which provides for enforcement in cases where there is documentation of resource damage, but has not yet demonstrated the ability of this authority to ensure implementation of the agricultural management measures. In material provided subsequent to the program submittal, Michigan indicates that "NRCS's whole farm planning is the most effective way to implement the requirements of Section 6217." Michigan needs to include in its strategy a description of how the Agricultural Best Management Practices Manual, the GAAMPs, and other programs (e.g., whole farm planning) will be used, either alone or in combination, to ensure implementation of the agricultural management measures. III. FORESTRY FINDING: Michigan's program includes management measures in conformity with the 6217(g) guidance. Michigan has identified a back-up enforceable policy and mechanism for the forestry management measures but has not yet demonstrated the ability of this authority to ensure implementation of the management measures throughout the 6217 management area. CONDITION: Within one year, Michigan will develop a strategy (in accordance with Section XIV, page 16) to implement the forestry management measures throughout the 6217 management area. RATIONALE: Michigan's program, described in the Nonpoint Source Forest Land Strategy on pages 118-121 of the program submittal, contains several commendable voluntary efforts. These include the Water Quality Management Practices on Forest Lands BMP manual, educational programs and technical assistance, a Nonpoint Source Forest Land Strategy Committee, and field audits by interdisciplinary teams that will publish annual audit reports beginning in 1996. In addition (as described in supplemental material provided by Michigan), Michigan State University is developing training sessions for loggers on the use of forestry BMPs. As described on page 92 of the program submittal, Michigan's programs apply to "all sizes and classes of forest ownership and operations; there is no five acre threshold or exemption." According to supplemental material provided by the State, the Inland Lakes and Streams provisions of the Natural Resources and Environmental Protection Act (PA 451) can be used to address certain forestry activities, such as stream crossings for logging roads. These provisions apply to approximately 11,000 inland lakes and 36,350 miles of streams in Michigan. However, both the provisions of Act 451 and the Inland Lakes and Streams Act itself do not include a linkage to implementation of forestry BMPs in accordance with the BMP manual. Michigan has identified a back- up enforceable policy and mechanism, the Water Resources Commission Act, which provides for enforcement in cases where there is documentation of resource damage, but has not yet demonstrated the ability of this authority to ensure implementation of the forestry management measures. IV. URBAN A. NEW DEVELOPMENT FINDING: Michigan's program does not include management measures in conformity with the 6217(g) guidance. Michigan has identified a back-up enforceable policy and mechanism for this management measure but has not yet demonstrated the ability of this authority to ensure implementation throughout the 6217 management area. CONDITION: Within two years, Michigan will include in its program management measures in conformity with the 6217(g) guidance. Within one year, Michigan will develop a strategy (in accordance with Section XIV, page 16) to implement the new development management measure throughout the 6217 management area. RATIONALE: Rule 1709(3) of the Soil Erosion and Sedimentation Control Act (SESCA) provides that any facility designed to convey water around an earth change area must be designed to limit the flow to a non-erosive velocity. However, this provision does not require that facilities to control runoff be designed in accordance with the new development management measure with respect to peak runoff rate and volume and it does not call for permanent runoff controls that achieve 80% removal of total suspended solids (TSS) from post-development runoff. SESCA Rule 1709(2) provides that sediment caused by accelerated soil erosion shall be removed from runoff water before it leaves the site of the earth change. This authority addresses erosion control during construction, but it does not address the components of the new development measure. Even though SESCA maintains a "zero discharge" goal for sediment following construction, it does not includes provisions for post-development runoff in conformity with the 6217(g) guidance. Michigan needs to include in its program management measures that, either by design or performance, achieve the goals of the management measure. Michigan has identified a back-up enforceable policy and mechanism, the Water Resources Commission Act, which provides for enforcement in cases where there is documentation of resource damage, but has not yet demonstrated the ability of this authority to ensure implementation of the management measures. B. WATERSHED PROTECTION AND EXISTING DEVELOPMENT FINDINGS: Michigan's program includes management measures for watershed protection and existing development in conformity with the 6217(g) guidance, except for siting development to protect the natural integrity of waterbodies and natural drainage systems. Michigan has identified a back-up enforceable policy and mechanism for these management measures but has not yet demonstrated the ability of this authority to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Michigan will include in its program management measures for siting development to protect the natural integrity of waterbodies and natural drainage systems in conformity with the 6217(g) guidance for watershed protection. Within one year, Michigan will develop a strategy (in accordance with Section XIV, page 16) to implement the watershed protection and existing development management measures throughout the 6217 management area. RATIONALE: Michigan has a number of regulatory programs, including the Goemaere-Anderson Wetland Protection Act and the Flood Plain Control Act, that provide protection for specific areas such as wetlands and floodplains. The State has also begun to provide for increased inter-agency coordination on a watershed basis. Efforts such as the Grand Traverse Bay Watershed Initiative and the Huron River program serve as good examples of watershed protection efforts that are consistent with the objectives of this management measure. However, beyond the focus on important natural resources (wetlands, floodplains, and buffers), Michigan does not have a program that evaluates development from a broader perspective to ensure that watershed features are protected. The watershed protection measure is intended to provide goals to use in developing comprehensive programs for guiding future development in a manner that will prevent and mitigate the effects of nonpoint source pollution. The State addresses existing development through a number of programs such as the Rouge River National Wet Weather Demonstration Project, Clean Water Act section 319 watershed projects, watershed initiatives, the International Joint Commission designated Areas of Concern/Remedial Action Plan program and the municipal stormwater permitting program. As described in supplemental material provided by Michigan, there are fourteen Areas of Concern (AOCs), designated by the International Joint Commission as priority areas for addressing existing water quality problems. Though the designation of these AOCs was initially focused on point sources and contaminated sediments, the Remedial Action Plans (RAPs) now address nonpoint source pollution on a watershed basis. Schedules for implementing the RAPs are based on a three stage process, including definition of problems, actions needed to achieve restoration and a strategy for tracking progress, and documenting that restoration has been accomplished. According to the program submittal, deadlines for RAP development and reviews are included in the Great Lakes Critical Programs Act of 1990. Michigan has identified a back-up enforceable policy and mechanism, the Water Resources Commission Act, which provides for enforcement in cases where there is documentation of resource damage, but has not yet demonstrated the ability of this authority to ensure implementation of these management measures. We encourage Michigan to pursue a comprehensive watershed protection program that will address all coastal watersheds. C. SITE DEVELOPMENT FINDING: Michigan's program includes management measures in conformity with the 6217(g) guidance, except for protecting areas that provide important water quality benefits and limiting disturbance of natural drainage features, and includes enforceable policies and mechanisms to ensure implementation. CONDITION: Within three years, Michigan will include in its program management measures in conformity with the 6217(g) guidance for site development. RATIONALE: Michigan partially implements this management measure through Rule 1709 of the Soil Erosion and Sedimentation Control Act (SESCA), which "requires earth changes ... to limit the exposed area for the shortest possible period of time." In addition, the Flood Plain Control Act, the Inland Lakes and Streams Act, and the Natural River Act provide protection for certain natural areas through the permit review process. In supplemental material provided by the State, Michigan proposes that routine permit conditions require minimizing land disturbance and removal of vegetation, however, no standard set of conditions to accomplish these objectives was provided and it remains unclear that conditions on routinely issued permits cover the full range of activities described in the management measure. As discussed on page 19 of the program submittal, the Michigan Department of Environmental Quality (MDEQ - formerly Department of Natural Resources) is currently working to improve the program by drafting revised legislation to strengthen the Soil Erosion and Sedimentation Control Act. Amending the SESCA to include site level management measures or otherwise establishing standard permit conditions in rules that apply to all site development activities could provide the opportunity to achieve full conformity with this management measure. D. CONSTRUCTION SITE EROSION AND SEDIMENT CONTROL FINDING: Michigan's program includes management measures in conformity with the 6217(g) guidance, except for construction sites that disturb less than one acre or are not within 500 feet of a lake or stream, and includes enforceable policies and mechanisms to ensure implementation. CONDITION: Within two years, Michigan will include in its program management measures in conformity with the 6217(g) guidance, or demonstrate that exemptions do not preclude the State from fully implementing the management measure for construction site erosion and sediment control throughout the 6217 management area. RATIONALE: Act #347, SESCA, provides for implementation of this management measure through local program delegation. Rule 1709 of SESCA requires the installation and continued maintenance of permanent soil erosion control measures to ensure that the site is stabilized. Landowners or developers who contract for or allow earth changes are required to obtain permits and prepare soil erosion and sedimentation plans. The provisions of SESCA are in conformity with the 6217(g) management measure, except that they do not apply to construction activities that disturb less than one acre of land or are not within 500 feet of a lake or stream. The 6217(g) management measure applies to construction activities that disturb over 5,000 square feet. Michigan needs to address the current exemptions for land disturbances of less than one acre (but greater than 5,000 square feet). In supplemental material provided by the State, Michigan proposes that wetlands may be added to the list of waterbodies for which soil disturbance activities would be subject to regulation (if within 500 feet of a wetland). However, Michigan has not yet demonstrated that current exemptions do not preclude the State from fully implementing the management measure for construction site erosion and sediment control throughout the 6217 management area. Michigan also noted on page 19 of the program submittal that, as currently written, there are limitations to the SESCA and inconsistencies between SESCA and the rules under the Act. Proposed changes include increasing the accountability of authorized public agencies, requiring restoration of off-site impacts and reducing or modifying exemptions. NOAA and EPA encourage the State to strengthen the SESCA as proposed in the program submittal. E. CONSTRUCTION SITE CHEMICAL CONTROL FINDING: Michigan's program does not include management measures in conformity with the 6217(g) guidance, but includes enforceable policies and mechanisms to ensure implementation. CONDITION: Within two years, Michigan will include in its program management measures in conformity with the 6217(g) guidance. RATIONALE: Michigan currently lacks specific program elements that address the proper management and application of chemicals, nutrients and toxic substances on construction sites. The program submittal describes training activities for authorized public agencies that administer the Soil Erosion and Sedimentation Control Act that include the use of soil tests to determine nutrient needs, but the toxic substances and chemical elements of this measure are not addressed by SESCA or its implementing rules. Michigan's Pesticide Control Act establishes procedures for the distribution, labeling and application of pesticides, including provisions that make it unlawful to apply pesticides in a manner inconsistent with the pesticide label. In addition, the Water Resource Commission Act provides authority to enter upon public and private property to conduct inspections or investigations where a person is causing or about to cause unlawful pollution of waters of the State. The Hazardous Waste Management Act restricts the use of hazardous materials. These authorities provide the State with enforceable policies and mechanisms that can be used to ensure implementation of this management measure. F. NEW AND OPERATING ONSITE DISPOSAL SYSTEMS (OSDS) FINDING: Michigan's program does not include management measures in conformity with the 6217(g) guidance and does not include enforceable policies and mechanisms to ensure implementation. CONDITION: Within three years, Michigan will include in its program management measures in conformity with the 6217(g) guidance. Within three years, Michigan will include in its program enforceable policies and mechanisms to ensure implementation of the new and operating onsite disposal system management measures throughout the 6217 management area. RATIONALE: Michigan's program does not include state criteria, guidance or other standards and specifications for OSDS in conformity with the 6217(g) management measures. In general, Michigan relies on county health departments to implement individual OSDS programs. The program submittal explains that the Michigan Department of Public Health has issued the "Michigan Guidelines for Subsurface Disposal" and the "Maintaining Your Septic System" brochure, but the State does not appear to play a role in ensuring that these guidelines are consistently applied in jurisdictions throughout the 6217 management area. These "Guidelines" are not binding or enforceable. Subsequent to the program submittal, Michigan provided NOAA and EPA with a document entitled "Michigan Criteria for Subsurface Sewage Disposal." However, the criteria specified in the document do not apply to private single and two family residential sewage systems constructed pursuant to local sanitary codes. Michigan has not documented that county health departments are consistently implementing OSDS requirements in conformity with the 6217(g) management measures. The State has also not described what actions the State may take where county health departments fail to implement an OSDS program. G. POLLUTION PREVENTION FINDING: Michigan's program provides for the implementation of management measures in conformity with the 6217(g) guidance. RATIONALE: Michigan's program includes a description of a variety of efforts to achieve this management measure. Educational materials have been and continue to be developed by the Nonpoint Source Program. The "Guidebook of BMPs for Michigan Watersheds" includes BMPs that address many elements of the management measure and several publications have also been developed for specific watershed projects. The Protecting Michigan's Future Bond Program/Solid Waste Alternatives Program has the potential to become an excellent vehicle for implementing and expanding nonpoint source pollution prevention management measures statewide. H. ROADS, HIGHWAYS AND BRIDGES FINDING: Michigan's program includes management measures for roads, highways, and bridges in conformity with the 6217(g) guidance except for the construction site chemical control measure for construction sites of less than 5 acres. Michigan has identified a back-up enforceable authority for this management measure but has not yet demonstrated its ability to ensure implementation of the management measures throughout the 6217 management area. CONDITION: For construction site chemical control, Michigan will, within two years, include in its program management measures in conformity with the 6217(g) guidance. Within one year, Michigan will develop a strategy (in accordance with Section XIV, page 16) to implement the management measures for roads, highways and bridges. RATIONALE: As described on pages 83-89 of the program submittal, Michigan has programs, including design review, operation and maintenance, and project inspection, to implement the roads, highways and bridges management measures, with the exception of the construction site chemical control requirements, which is limited to sites of 5 acres or more. Michigan has identified a back-up enforceable policy and mechanism, the Water Resources Commission Act, which provides for enforcement in cases where there is documentation of resource damage, but has not yet demonstrated the ability of this authority to ensure implementation of these management measures. Existing enforceable policies under the Michigan Water Resources Commission Act, Part 21 Rules, require construction sites to have approved equipment and storage areas; Part 5 Rules require adequate facilities to contain accidental spills and to comply with reporting procedures. However, Michigan needs to modify its program to provide enforceable policies and mechanisms or demonstrate that existing authorities can ensure implementation for the roads, highways and bridges management measures for construction sites of less than 5 acres. V. MARINAS AND RECREATIONAL BOATING FINDING: Michigan's program includes management measures in conformity with the 6217(g) guidance, except for stormwater runoff, and includes enforceable policies and mechanisms to ensure implementation. CONDITION: Within three years, Michigan will include in its program management measures for stormwater runoff in conformity with the 6217(g) guidance. RATIONALE: Under the Great Lakes Submerged Lands Act, Michigan requires a permit for new and expanding marinas. Permit applications must include an environmental assessment. All permit applications are subject to public review and comment, and violations are punishable by fines. Permit approvals are based on design review, engineering data, and consideration of environmental impacts. Flushing requirements and water quality assessments are not of primary concern in the State's process, but can be required as determined by the State based on its review of permit applications and plans. Michigan's program, however, does not adequately address the management measure for stormwater runoff. The program submittal does not describe how the State will implement the 80% reduction in TSS from hull maintenance areas and does not cite enforceable policies and mechanisms to ensure implementation. In supplemental material provided by the State, Michigan indicates that runoff from marinas may be addressed through a general stormwater permit issued under the National Pollutant Discharge Elimination System (NPDES), but Michigan has not yet issued such a general permit. If Michigan chooses to issue either general or specific NPDES permits that include stormwater runoff from marina facilities, those facilities will be exempt from coastal nonpoint program requirements for marina stormwater runoff once the permits are issued. Michigan requires all marinas with dockage for 15 or more vessels capable of having holding tanks to provide on-site pumpout services. Michigan has numerous laws and programs designed to assure that marinas and boat operators implement operation and maintenance measures. These include the Marine Safety Act; Cleaning Agents and Water Conditioners Act; Used Oil Recycling Act; Water Pollution Control Act; Rule 10; Rules for Storage of Flammable and Combustible Liquids; and Department of Health reviews of pumpout system plans. As described in the program submittal, Michigan has identified some problem areas in implementing programs for operation and maintenance that need to be addressed. NOAA and EPA encourage the State to further improve outreach efforts and other program refinements to effectively implement the management measures. VI. HYDROMODIFICATION FINDING: Michigan's program includes management measures in conformity with the 6217(g) guidance, except for eroding streambanks and shorelines, and includes enforceable policies and mechanisms to ensure implementation, except exemptions in Michigan's Drain Code preclude the State from fully implementing management measures for new channelization projects. CONDITION: Within one year, Michigan will develop a process to address new channelization projects which are not reviewed under existing authorities. Within three years, Michigan will include in its program management measures in conformity with the 6217(g) guidance for eroding streambanks and shorelines. RATIONALE: Michigan streams may be modified either through designation as a county drain under the Michigan Drain Code, or by permit under the Inland Lakes and Streams Act. Channel projects permitted under the Inland Lakes and Streams Act are reviewed for their potential effects on fish, wildlife, and other natural resources. However, channels constructed under the Michigan Drain Code are exempt from the permitting requirements of the Inland Lakes and Streams Act, and are not otherwise required to be evaluated for their effects on surface water quality and instream and riparian habitat. This exemption precludes the State from fully implementing management measures for channelization since it does not ensure that new projects are evaluated for effects on surface water quality and habitat, and are planned and designed to reduce undesirable impacts. Michigan implements management measures for the operation and maintenance of existing modified channels through County Drain Commissioners, who are responsible for periodic inspection of drains to determine their integrity. Erosion or obstructions can, but are not required to be, repaired by the County Drain Commissioners. For other permitted channels which are found to have significant effects on water quality or habitat, State agencies work cooperatively to address problems on a watershed basis. For instance, the Saginaw Bay Watershed Initiative has been established to address nonpoint source problems in surface waters, including those that result from channelization projects. The State is encouraged to pursue additional efforts to address nonpoint source problems from channelization in other watersheds where existing modified channels affect surface water quality and habitat. Michigan requires a soil erosion and sedimentation plan and permit for construction of new dams and repair of existing dams. The State also licenses and regulates the generation, storage, treatment and disposal of hazardous waste and has adequate authorities to control pesticides and prevent or contain spills of other substances. Litter control at dam construction sites will be implemented through the Littering Act, which prohibits the littering of waterways. New dam construction, as well as the reconstruction and alteration of existing dams, is reviewed under the Dam Safety Act and Inland Lakes and Streams Act, for the possible effects of the proposed activities on habitat for fish and wildlife. Recommendations are made to provide for fish ladders, run-of-the- river operation, minimum flow releases, cold water releases, etc. The Dam Safety Act also gives Michigan the authority to limit operations at all dams where significant damage to natural resources is occurring or is anticipated to occur due to the operation of a dam. The State's program does not include management measures for nonpoint source problems associated with excessive surface water withdrawals, but, according to supplemental information provided by the State, significant coastal water quality problems associated with excessive surface water withdrawals have not been documented in Michigan. Management measures for eroding shorelines and streambanks are implemented through permits required for streambank stabilization activities and the use of vegetative methods is encouraged, when appropriate. The State has also undertaken a number of projects to address shoreline and streambank erosion problems for water quality improvement, and utilizes U.S. Department of Agriculture (USDA) cost-share funds and Clean Water Act 319 grants to encourage local communities to address streambank erosion. Management measures to protect shoreline and streambank features with the potential to reduce nonpoint source pollution are also implemented through designation of Critical Sand Dune Areas and through regulation of vegetation removal in designated buffer strips on Natural Rivers. County Drain Commissioners may also assess property owners for streambank stabilization and correction of other erosion or sedimentation problems within designated agricultural drains. However, the limited application of these efforts does not constitute a process that has identified and protected streambank and shoreline features with the potential to reduce nonpoint source pollution. In addition, the State's program does not include management measures for uses of the shorelands or adjacent waters which can result in erosion of shorelines and streambanks. VII. WETLANDS, RIPARIAN AREAS AND VEGETATED TREATMENT SYSTEMS FINDING: Michigan's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation. RATIONALE: The Goemaere-Anderson Wetland Protection Act, the Inland Lakes and Streams Act, and the Great Lakes Submerged Lands Act are used to protect wetlands and riparian areas from the effects of new activities which can impact these areas. These laws require permits for activities involving dredge and fill activities in wetlands. The Michigan DEQ has the authority to impose conditions on permits to mitigate the impact of a wetland fill, to improve water quality as part of a proposed project, or to provide mitigation for unavoidable impacts involving lost wetland functions. In addition, Michigan implements the wetlands protection program under 404 of the Clean Water Act and the administrative responsibilities for this Federal program have been assumed by the State since 1984. Water quality impacts are considered in the permit review process, and 404 permits are not issued for activities which would result in a violation of State water quality standards. Michigan's program also implements management measures to protect nonpoint source functions within wetlands and riparian areas from existing conditions within the wetlands themselves, as well as from the effects of activities upstream in the watershed. This is accomplished through special Watershed Initiatives, which identify priority areas for wetlands protection and restoration in selected watersheds. The State utilizes funds and technical assistance provided through Clean Water Act 319 and Coastal Zone Management Act grants to encourage local governments and communities to implement BMPs on a watershed basis for wetlands protection and restoration. These approaches are supplemented by a program of State wetlands acquisition, encouragement of wetlands easements, designation of Environmental Areas to protect coastal wetlands and adjacent uplands, and encouragement of private wetlands acquisition efforts. Instruments such as tax reversion and land exchange are also utilized to maximize acquisition efforts. Potential nonpoint inputs to wetlands from upstream sources are controlled at the site through regulation of soil erosion and sediment control, assessments conducted under the Natural Resources and Environmental Control Act, and permits issued under the Inland Lakes and Streams Act. The Wetlands Protection Act requires consideration of cumulative impacts to a wetland during the permit review process for new projects, and guidelines are under development for staff to use in improving cumulative impact assessment methodology. Michigan intends to implement the management measure promoting restoration of wetlands and riparian areas through education and incentive programs, and through cooperative efforts between government agencies, such as the U.S. Fish and Wildlife Service North American Waterfowl Management Plan and USDA programs. The Michigan Drain Code Program also provides for restoration of wetlands in drains which have ceased to be of public utility. Michigan is encouraged to utilize these practices and programs to implement the management measure. Michigan intends to implement the management measure to promote vegetated treatment systems through the review of permits for wetlands alterations and stormwater discharges, and through the encouragement of local zoning ordinances which require vegetated treatment systems for treatment of runoff between new construction and surface waters. Michigan is encouraged to utilize these practices and programs to implement the management measure. VIII. ADMINISTRATIVE COORDINATION FINDING: Michigan's program establishes mechanisms to improve coordination among State agencies and between State and local officials. RATIONALE: Coordination mechanisms include joint agency permit reviews for projects that involve overlapping jurisdiction and an Interagency Nonpoint Source Advisory Committee. Several Memorandums of Agreement have been established that outline coordination between divisions within State offices, between State departments and between State and federal agencies. Other coordination mechanisms include a Natural Resources Conservation Service (NRCS) liaison between the U.S. Department of Agriculture and MDEQ and a Surface Water Quality Division funded position within the Michigan Department of Agriculture. Proposed improvements to the Soil Erosion and Sedimentation Control Act includes increased coordination between the MDEQ and local implementing agencies. IX. PUBLIC PARTICIPATION FINDING: Michigan's program provides opportunities for public participation in the development and implementation of the coastal nonpoint program. RATIONALE: The program submittal describes several activities that provide opportunities for public participation in the development and implementation of Michigan's coastal nonpoint program. Michigan created an advisory committee representing a variety of constituency groups and workgroups for each nonpoint source category. Michigan also conducted an extensive public education and outreach campaign targeted at the public and affected interests. Michigan held three public meetings across the State to solicit public input. Michigan provided a 30-day public comment period on the final program submittal and received eight comment letters during this period. The State responded to these comments. Michigan plans to collaborate with other State and federal agencies, local units of government and interest groups on nonpoint source issues and continue to evaluate and improve programs through cooperative efforts. X. TECHNICAL ASSISTANCE FINDING: Michigan has included programs that will provide technical assistance to local governments and the public for implementing additional management measures. RATIONALE: Technical assistance is provided through MDEQ's Section 319 program, which has developed several technical assistance manuals to encourage implementation of best management practices. The Michigan State University Cooperative Extension and the USDA's Natural Resources Conservation Service (NRCS) provide extensive technical assistance regarding soil erosion control, water quality protection, and general pollution prevention practices. A NRCS employee is on detail to MDEQ and a MDEQ funded inspector in the Michigan Department of Agriculture provides technical assistance to farmers. The Saginaw Bay Wetlands restoration feasibility study is also providing technical assistance to farmers in the watershed. MDEQ conducts training sessions for local enforcing agencies statewide and technical assistance is also provided to local enforcing agencies through the audit program. Proposed improvements to the Soil Erosion and Sedimentation Control Act includes increased technical assistance to local implementing agencies. MDEQ has also proposed a cooperative effort between the State and the boating industry to educate marina owners and operators. These proposed efforts would include workshops, training and educational materials. XI. ADDITIONAL MANAGEMENT MEASURES FINDING: Michigan's program provides for the implementation and continuing revision of additional management measures applicable to critical coastal areas and to cases where (g) measures are fully implemented but water quality threats or impairments persist. RATIONALE: Supplemental information provided by Michigan during the program review identifies the Remedial Action Plan (RAP) process for Areas of Concern (AOCs) as the mechanism for determining additional management measures. In addition, the Grand Traverse and Saginaw Bay watershed initiatives include 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. The RAP process establishes a technical review, inter-jurisdictional coordination, and public involvement that will be used to determine what additional management measures may be needed, and how they will be implemented. XII. CRITICAL COASTAL AREAS FINDING: Michigan's program identifies and includes a process for the continuing identification of critical coastal areas adjacent to impaired and threatened coastal waters. RATIONALE: Michigan has identified a number of critical coastal areas, including the Areas of Concern (AOCs) and the Grand Traverse Bay and Saginaw Bay Watersheds, both of which include 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. Although there is a process for designating additional Areas of Concern, the current focus of the program is on developing Remedial Action Plans for existing AOCs. While NOAA and EPA encourage states to include previously designated areas within the critical coastal areas under this program, NOAA and EPA are concerned that the AOC designation may not fully address all areas, including those areas in which new or substantially expanding land uses may cause or contribute to the impairment of coastal waters. Therefore, we encourage the State to consider expanding its process for identifying and addressing areas with new or expanding land uses. XIII. MONITORING FINDING: Michigan's program does not include a plan to assess over time the success of the management measures in reducing pollution loads and improving water quality. CONDITION: Within one year, Michigan will develop 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: In the program submittal, Michigan provides an overview of several existing monitoring programs, but does not describe how they will be applied to the section 6217 program. It appears that Michigan could identify efforts under its nonpoint source monitoring strategy that can be used to assess over time the success of the management measures in reducing pollution loads and improving water quality at both the watershed and site-specific scales. For example, the watershed evaluation monitoring described on page 196 could be applied to measure the pollutant load reductions achieved due to implementation of management measures throughout a watershed, yet the State identifies no watersheds where such an effort will be undertaken. In addition, Michigan states that the source identification monitoring generates data that "allows for the evaluation of the effectiveness of BMPs," which clearly indicates that such monitoring could also be used to provide site-specific assessments of management measure effectiveness. Michigan should not need to undertake additional monitoring to achieve the monitoring objectives of section 6217. It is stated on page 200 of the program submittal that Michigan will continue its existing monitoring programs, and Michigan states that this monitoring will support the coastal nonpoint source control program. Management measure tracking should be incorporated into Michigan's plan to evaluate the effectiveness of management measures in controlling nonpoint source pollution. This will enable the State to relate such implementation to changes in water quality or pollutant loads. XIV. STRATEGY AND EVALUATION FOR BACK-UP AUTHORITIES As noted above in the source category sections, within one year, Michigan will develop a strategy to implement the management measures for agriculture, forestry, urban (new development, watershed protection and existing development), and roads, highways and bridges sources 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 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, Michigan 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.
