FINDINGS FOR THE WISCONSIN COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the State of Wisconsin pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the Wisconsin Coastal Nonpoint Program, Final Program Submittal, July 1995 and supplemental material provided by Wisconsin 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 Wisconsin 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 Wisconsin 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 Wisconsin's program. It also provides the rationale for the findings and includes conditions that will need to be met for Wisconsin 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 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 Wisconsin Coastal Nonpoint Program, Final Program Submittal, July 1995 ("program submittal"). NOAA and EPA have written this document as succinctly as possible. We have relied upon, but do not repeat here, the extensive information that the State has included in its program submittal. Further information and analysis, including material provided by Wisconsin 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: Diana Olinger (301/713-3113, x168) 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: Wisconsin's proposed boundary for the 6217 management area is sufficient to control the land and water uses that have or are reasonably expected to have a significant impact on Wisconsin's coastal waters. RATIONALE: Wisconsin's proposed boundary follows the basic NOAA recommendation of coastal watersheds, with the exception of the area draining to the Brule River that forms part of the Wisconsin-Michigan state line. Wisconsin has proposed to exclude an area in Vilas County, along the Wisconsin-Michigan border, that drains north through Michigan to Lake Superior. This area does not drain to the coastal waters of Wisconsin. II. AGRICULTURE FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance, except for the measures to address confined animal facilities and nutrient management. Wisconsin has presented sufficient justification for exclusion of the irrigation water management measure for irrigated agricultural lands. The State has identified backup enforceable policies and mechanisms for implementing the agricultural management measures but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Wisconsin will (1) modify the design storm for animal lot runoff management to be in conformity with the two management measures for confined animal facilities and include storage of wastewater and runoff for Large Units, and (2) include management measures in conformity with the (g) guidance for nutrient management. Within one year, Wisconsin will develop a strategy (in accordance with Section XIV, page 16) to implement the agricultural management measures throughout the 6217 management area. RATIONALE: In the program submittal, Wisconsin proposed an alternative management measure for confined animal facilities, relying on the 10-year, 24-hour frequency storm for system design. The State's proposed measure is not as effective as the 6217(g) management measure, which is based on the larger, 25- year, 24-hour design storm. Wisconsin's proposed alternative for large facilities also does not specify storage of both the facility wastewater and runoff. On page 6-21 of the program document, Wisconsin states it is "considering changing to the 25-year, 24- hour design storm for animal lot runoff management." The condition is intended to provide Wisconsin a reasonable schedule to implement the change to the 25-year storm for both the B1 and B2 (large and small units) management measures. Wisconsin has also proposed an alternative management measure for the nutrient management measure. Wisconsin has proposed changing part (5) from "use of the limiting nutrient concept", to "limit nitrogen", and part (6) from "avoid applications ... to frozen soil" to "manage applications ... to frozen soil." Wisconsin's proposed approach to limit only the amount of nitrogen applied creates the potential for excessive application and delivery to the aquatic environment of other nutrients, most notably phosphorus, that may be harmful to Wisconsin's fresh coastal waters. The 6217(g) management measure achieves efficient use of all nutrients (N, P, and K) by applying only the amounts needed by the crop (i.e., the limiting nutrient concept), thus minimizing the potential for export of harmful nutrients to the aquatic environment. Wisconsin needs to incorporate the limiting nutrient concept and avoid, as much as possible, applications to frozen soil and during periods of leaching and runoff. In addition, Wisconsin's proposal to "manage applications" is less effective than the 6217(g) management measure, since it provides no assurance that applications are minimized during periods of snowmelt, runoff, or leaching that have higher potential to cause harm to coastal waters. Wisconsin has demonstrated that irrigation is not a significant contributor of pollutants to Wisconsin's coastal waters. As described on page 6-31 of the program submittal, there were only 5,079 acres irrigated in the nine counties located wholly within the 6217 management area. For those counties with a portion of their jurisdiction within the 6217 management area, most of the irrigation occurs outside of the management area. The relatively low acreage of irrigated land and the use of drip or spray irrigation in the 6217 management area demonstrate that Wisconsin's exclusion of irrigation from its program is justified. Wisconsin has backup enforcement authority for the agricultural management measures through its regulations for Nonpoint Source (NPS) Orders (144.025(u) and (v)), which state that the "department ... may order or cause the abatement of pollution which the department has determined to be significant and caused by a nonpoint source", including "pollution which causes a water quality standard violation, [or] pollution which significantly impairs aquatic habitat or organisms." NPS Orders do not address pollution caused primarily by animal waste. The Animal Waste Management Program addresses point source operations and other animal feeding operations (those less than 1000 AUs) if "the department determines through an onsite investigation that unacceptable practices of the operation are causing or have caused the discharge of a significant amount of pollutants to waters of the state." Failure of the operation to comply will result in the facility being required to apply for a Wisconsin point source permit. III. FORESTRY FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance. The State has enforceable policies and mechanisms to ensure implementation of the forestry management measures for state and county forests and for certain activities, such as a stream crossing. Wisconsin has identified backup enforceable policies and mechanisms for implementing the forestry measures on private lands and for the full range of forestry activities, but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. Wisconsin has provided sufficient justification to support an exclusion of cable yarding from its program. CONDITION: Within one year, Wisconsin will develop a strategy (in accordance with Section XIV, page 16) to implement the forestry management measures on lands other than state and county lands throughout the 6217 management area. RATIONALE: Wisconsin's program submittal describes several commendable voluntary efforts, including Wisconsin's Forestry Best Management Practices for Water Quality: A Field Manual for Loggers, Landowners and Land Managers, a series of best management practice (BMP) education and training workshops, the Cooperative Consulting Foresters Program, tax incentives, and a monitoring program that "will begin in July, 1995 and continue for several years." Wisconsin's Nonpoint Source Orders (144.025 (u) and (v)) allow the Department of Natural Resources to take action against silvicultural operations causing impairments of water quality. Management measures are implemented as a matter of policy and procedure on state and county forests, on private forest lands managed by Cooperating Consultant Foresters, or on lands which are voluntarily enrolled in the Managed Forest Law and Forest Stewardship programs. Additionally, several forest industry companies in Wisconsin have adopted Wisconsin's forestry BMPs as part of their corporate land management policies. As described in the program submittal, Chapter 28, Wisconsin Statutes, includes requirements for management of state and county forests. Sections 28.04 and 28.11 require plans to be prepared that include consideration of the forestry management measures. On county forests, timber harvesting cannot be conducted until a cutting notice is received from the Department of Natural Resources. Private forest lands may be required to implement some components of the forestry management measures during silvicultural activities. These include preharvest notification requirements, stream crossing restrictions (permits) in accordance with Chapter 30, and additional zoning restrictions for ownerships within Wisconsin's Shoreland Management Program area. The Shoreland Management program sets minimum road building and harvesting standards for streamside management areas and some forested wetlands. Wisconsin has also developed a monitoring program to evaluate BMP implementation. NOAA and EPA encourage the State to incorporate this effort and the activities described on page 7-37 of the program submittal into a strategy to ensure implementation throughout the 6217 management area. Wisconsin's proposed exclusion for the cable yarding element of the timber harvesting management measure is justified because "no such activity is now occurring, nor is anticipated to occur within the State" (p. 7-37 of Wisconsin's program). IV. URBAN A. NEW DEVELOPMENT FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance except for development activities less than 5 acres in area. The State has identified a backup enforceable policy and mechanism for implementing this management measure but has not yet demonstrated the ability of the authority to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Wisconsin will include in its program management measures in conformity with the 6217(g) guidance for new development activities less than 5 acres in area. Within one year, Wisconsin will develop a strategy (in accordance with Section XIV, page 16) to implement the new development management measure throughout the 6217 management area. RATIONALE: Wisconsin regulates construction and development activities for sites exceeding 5 acres through its National Pollutant Discharge Elimination System (NPDES) stormwater permit program (Chapter NR 216, Wis. Adm. Code). In the program submittal, the State has proposed standards that would be implemented for construction sites and commercial building projects that are less than 5 acres in size and not otherwise exempted. For these latter projects, the alternative that the State has provided would control the 1.5-year, 24-hour storm and not the 2-year, 24-hour storm. Under State analysis, this alternative would reduce total suspended solid loadings by greater than 80%. This alternative would be consistent with the objectives of the new development management measure. The State's proposed standards, however, exclude post-construction management, thereby failing to address post-development runoff. Wisconsin has proposed the development of local stormwater ordinances to implement the new development management measure for sites not covered by its NPDES program. The State's draft technical design manual for stormwater best management practices (October 1, 1995), which was provided to NOAA and EPA after the initial program submittal, includes a draft model stormwater management zoning ordinance. Under State enabling legislation, counties, villages, and cities are authorized to regulate stormwater through the adoption of ordinances. The State's model ordinance includes requirements in conformity with the new development management measure. Where adopted, the ordinance would require a permit and stormwater management plan for residential development on 5 or more acres; residential development on at least 3 acres, but less than 5 acres, if there is at least 1.5 acres of impervious surface; and non-residential development with an area of 1.5 acres or more, or that creates more than .5 acre of impervious surface. In addition, the ordinance would cover any land development activity, regardless of size, that is determined likely to result in erosion or pollution. NOAA and EPA encourage the State to finalize the technical manual and ordinance and begin efforts to assist local governments in adopting it. In Section 8.2 of the program submittal, which describes urban water quality programs, Wisconsin identifies a backup enforcement authority for this management measure through its regulations for NPS Orders (144.025(u) and (v)), which state that the "department ... may order or cause the abatement of pollution which the department has determined to be significant and caused by a nonpoint source", including "pollution which causes a water quality standard violation, [or] pollution which significantly impairs aquatic habitat or organisms." B. WATERSHED PROTECTION and EXISTING DEVELOPMENT FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance and enforceable policies and mechanisms to ensure implementation. RATIONALE: Wisconsin, through the requirements for Areawide Water Quality Management Plans, provides water quality management plans for all sewer service areas of the State. All watersheds in each area must be identified in the plan and water quality problems for each assessed. This program provides a strong foundation for watershed level protection. Wetlands and other areas unsuitable for installation of waste treatment systems are considered for exclusion from coverage by water and sewer. While areas not served by public sewage systems are not addressed by the sewer service area plans, these areas may be covered under the priority watershed program by NR 120. Under this program, watershed plans to identify water quality problems and set objectives to maintain and improve water quality are developed. In addition, Wisconsin's Shoreland Management Program (NR 115, Wis. Adm. Code) and Floodplain Management Program (NR 116, Wis Adm. Code) serve to avoid conversion of areas that are particularly susceptible to erosion or provide important water quality benefits. Potential environmental impacts due to road, highway and bridge development must be considered under numerous administrative codes (listed on page 8-15 of the program submittal) of the Wisconsin Department of Transportation (WisDOT) and criteria specified in the Facilities Development Manual. Through the development of watershed projects under the Wisconsin nonpoint source water pollution abatement program, opportunities for pollution and load reduction for existing development are identified in priority watershed plans. For each project, major sources of pollutants are identified and necessary pollutant reduction actions are incorporated into the plans. Retrofitting of urban runoff control structures is an element in some plans. Plans are implemented over an 8-10 year implementation period. The navigable waterways, shoreline, wetland and floodplain management programs provide protection of natural conveyance systems. C. SITE DEVELOPMENT FINDING: Wisconsin's program does not include management measures in conformity with the 6217(g) guidance. The program includes enforceable policies and mechanisms to ensure implementation in a substantial portion of the 6217 management area. However, the program does not yet include enforceable policies and mechanisms to ensure implementation throughout the management area. CONDITION: Within three years, Wisconsin will include in its program management measures in conformity with the 6217(g) guidance for site development and enforceable policies and mechanisms to ensure implementation of the site development management measure throughout the 6217 management area. RATIONALE: Wisconsin proposes to use a variety of programs to implement this management measure. Specific land use controls described in the program submittal include: the Floodplain and Shoreland Management programs and the Shoreland-Wetland Protection Program, which provide for protection of water quality through setbacks, preservation of shore cover, floodplain development restrictions and wetland protection. These programs generally implement the elements of the management measure by protecting areas that provide important water quality benefits and limiting disturbance of natural drainage features, but they do not ensure that sites are planned and developed in accordance with all of the elements of the management measure. This management measure is intended to provide controls and policies that are applied during the site planning and review process, including site selection and project design. The programs listed above do not provide for a planning review process that ensures the elements of the measure are considered. Such a process could be integrated with construction site erosion and sediment control. D. CONSTRUCTION SITE EROSION AND SEDIMENT CONTROL FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation, except for construction sites less than 5 acres that do not involve construction of one-family and two-family dwellings. CONDITION: Within two years, Wisconsin will provide in its program for implementation of the management measure on construction sites less than 5 acres that do not involve construction of one-family and two-family dwellings within the 6217 management area. RATIONALE: Wisconsin's program includes management measures for erosion and sediment control and enforceable policies and mechanisms for one and 2-family dwellings under the Uniform Dwelling Code (ILHR 21.125, Wis. Adm. Code). The Code requires erosion and sediment controls to prevent or reduce erosion until the disturbed areas have been stabilized. Enforcement occurs through State-certified building inspectors with the State retaining oversight authority. Compliance can be required through orders, fines and withholding of building occupancy permits. The Wisconsin Construction Site Best Management Practice Handbook serves as a reference for the Construction Standards contained in the Uniform Dwelling Code. However, the Uniform Dwelling Code is limited in scope, and a number of construction activities are specifically excluded or omitted from coverage under this Code. In the program submittal, the State noted that it is developing administrative rules to require construction site erosion controls on all public (commercial) building sites. In order to achieve conformity with the 6217(g) guidance, multi-family dwellings, industrial sites and all other development activities such as utility developments or repairs, etc. need to receive similar coverage. E. CONSTRUCTION SITE CHEMICAL CONTROL FINDING: Wisconsin's program does not include management measures in conformity with the 6217(g) guidance. The State has identified back-up enforceable policies and mechanisms for implementing this management measure, but has not yet demonstrated the ability of these authorities to ensure implementation of throughout the 6217 management area. CONDITION: Within two years Wisconsin will include in its program management measures that are in conformity with the 6217(g) guidance. Within one year Wisconsin will develop a strategy (in accordance with Section XIV, page 16) to implement this management measure throughout the 6217 management area. RATIONALE: Wisconsin has state authority and general requirements concerning the regulation of hazardous and flammable wastes through Chapter NR 600, Wisconsin Administrative Code. The State also has incorporated pesticide and nutrient management measures into its Wisconsin Construction Site Best Management Practice Handbook. However, aside from the nutrient and pesticide practices listed in the BMP handbook, the State's program does not include policies or procedures to ensure proper construction site chemical control and proper storage and handling of toxic materials on construction sites. F. NEW and OPERATING ONSITE DISPOSAL SYSTEMS (OSDS) FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation. RATIONALE: Wisconsin has a well-developed OSDS program, which has been delegated to the county level. The program includes sanitary permits and the enforcement authority to ensure proper siting, construction, operation and maintenance and repair or replacement. Wisconsin's Private Sewage System Replacement or Rehabilitation Grant Program (ILHR 87, Wis. Adm. Code) provides funds to participating counties to ensure replacement of failing systems. ILHR 87.07 (4)(b)(4) requires that county programs include a maintenance program that provides for inspections at least once every three years. NOAA and EPA encourage Wisconsin to work with the remaining two counties in the Lake Superior drainage basin who do not yet participate in this program. In the program submittal, Wisconsin proposes that the elements of these management measures addressing nitrogen- limited surface waters do not apply because coastal waters in Wisconsin are not nitrogen-limited. Even so, the State describes programs that address nitrogen reduction and there is ongoing research of alternative designs. NOAA and EPA encourage Wisconsin to continue these efforts to ensure that significant ground water nitrogen loadings from OSDS do not adversely impact surface waters. G. POLLUTION PREVENTION FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance. RATIONALE: As described on pages 8-31 to 8-33 of the program submittal, Wisconsin has a number of programs that address all of the elements of the management measure. The State is encouraged to consider additional pollution prevention activities for commercial entities aside from the vehicle fluids management program. H. ROADS, HIGHWAYS, AND BRIDGES FINDING: Wisconsin's program includes management measures for roads, highways, and bridges in conformity with the 6217(g) guidance except for the runoff systems management measure. Wisconsin's program includes enforceable policies and mechanisms to implement the management measures. CONDITION: Within three years, Wisconsin will include in its program a management measure that is in conformity with the 6217(g) guidance for runoff systems. RATIONALE: The Wisconsin Department of Transportation (WisDOT), through programs established by the Wisconsin Environmental Policy Act (WEPA) and Chapter 85, Wisconsin Statutes, administers a comprehensive road, highway, and bridge development and operation and maintenance program for all state- owned transportation projects. City and county local roads must meet state standards and are overseen by WisDOT under the Local Roads Improvement Program. Section 85.16 provides the basis for WisDOT to develop administrative rules and forms that are used by WisDOT to implement its programs. As described on pages 8-35 to 8-36 of the program submittal, WisDOT uses a number of regulations and procedures, including the WisDOT Standard Specifications for Road and Bridge Construction (1989), to ensure that roads and highways are properly planned, sited and developed. In addition to the procedures used for siting and design of roads, the Wisconsin Department of Natural Resources (DNR) also issues permits for all local projects over or near waters. WisDOT and DNR have a cooperative agreement under which road, highway and bridge projects over or near waters are reviewed to protect water quality, specifications are developed and required in contracts, and sites are monitored for compliance. Construction site erosion and sediment control is implemented under the authority of section 85.19, Wis. Stats., which requires WisDOT to establish standards for control of soil erosion related to highway and bridge construction that is funded in whole or in part with State or Federal highway funds. The erosion and sediment control standards included in Chapter 10 of the Facilities Development Manual are in conformity with the 6217(g) management measure, but planned revisions to incorporate additional BMP information and specifications will improve the overall program. The Hazardous Materials Management Manual contains procedures which meet the management measure for construction chemical control. WisDOT trained safety/project engineers and DNR Wardens are responsible for compliance and inspection of sites. WisDOT has established maintenance procedures in the Facilities Maintenance Manual, which includes policies limiting the application of salt, limiting the use of weed control and requiring cross-compliance with ATCP 29, Wisc. Adm. Code, Pesticide Use and Control and NR 80, Wis. Adm. Code, Use of Pesticides on Land and Water Areas of the State of Wisconsin. As described on page 8-41 of the program submittal, WisDOT has incorporated pollution prevention procedures into some of the operation and maintenance procedures for roads, highways and bridges and is evaluating any additional steps that may be necessary. NOAA and EPA encourage Wisconsin to further develop pollution prevention practices that may provide additional reduction of pollutant loadings to surface waters. WisDOT is evaluating the extent to which it can implement the runoff systems management measure, but is only beginning to implement runoff controls from existing roads, highways and bridges under municipal stormwater permit requirements. It appears that municipal and county governments can identify improvement projects under the Local Roads Improvement Program that could include improvements to road, highway and bridge runoff systems. V. MARINAS AND RECREATIONAL BOATING FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance, except for solid waste, fish waste, liquid material, petroleum control, and boat cleaning, and includes enforceable policies and mechanisms to ensure implementation, except for solid waste, fish waste, liquid material, petroleum control, and boat cleaning. The State has identified a backup enforceable policy and mechanism for implementing the solid waste, fish waste, liquid material, petroleum control, and boat cleaning management measures but has not yet demonstrated the ability of this authority to ensure implementation throughout the 6217 management area. CONDITION: Within one year, Wisconsin will develop a strategy (in accordance with Section XIV, page 16) to implement the solid waste, fish waste, liquid material, petroleum control, and boat cleaning management measures throughout the 6217 management area. Within three years, Wisconsin will include in its program management measures for solid waste, fish waste, liquid material, petroleum control, and boat cleaning in conformity with the 6217(g) guidance. RATIONALE: Wisconsin requires a permit under Chapter 30, (Wis. Stats., Navigable Waters, Harbors, and Navigation), for new and expanding marina projects. Chapter 30 prohibits placement of any structure or deposit, dredging, and diversion of any water in or from navigable waters of the State, except as permitted under statute. Permit applications to the DNR trigger a detailed staff review process of design and siting requirements at new and expanding marinas for flushing, water quality, habitat protection, shoreline stabilization, and storm water runoff (when not part of an NPDES permit). State regulations address fueling station design (ILHR 10, Wis. Adm. Code) and sewage facilities (ILHR 86, Wisc. Adm. Code). Wisconsin is considering legislation that would require that all marinas on the Great Lakes have sewage pumpout facilities by January, 1999. NOAA and EPA encourage the State to pursue this legislation to further reduce the potential for release of sewage to surface waters. Wisconsin has identified Chapter 29, Wis. Stats. as an authority to implement the operation and maintenance measures at marinas. Under Chapter 29, no person may throw, or deposit into waters oil, tar, garbage, refuse, debris, etc., including sewage from boats, or any other substance deleterious to fish and game. Chapter 29.29.3.c, specifies fines and penalties for violations. Wisconsin provides extensive outreach and training programs that stress environmental awareness and boating safety. The State encourages marina owners and operators to promote boater participation in these programs. As described in the program submittal, for solid waste, fish waste, liquid material, petroleum control, and boat cleaning, specific practices to implement these management measures are not specified. Wisconsin may wish to consider developing a BMP manual or other technical guidance document that marina owners and operators can use to implement these management measures. VI. HYDROMODIFICATION FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance, except for chemical and pollutant control at dams. Wisconsin's program does not include a process to identify and develop strategies to solve existing nonpoint source problems caused by streambank and shoreline erosion that do not come up for review under existing permit authorities. Wisconsin's program includes enforceable policies and mechanisms to ensure implementation. CONDITION: Within three years, Wisconsin will include in its program management measures for chemical and pollutant control at dams in conformity with the 6217(g) guidance and dams that are constructed on non-navigable waters. Within three years, Wisconsin will develop a process to identify and develop strategies to solve nonpoint source problems caused by streambank and shoreline erosion that do not come up for review under existing permit authorities. RATIONALE: Wisconsin requires permits for projects involving channel modifications and stabilization of shorelines or streambanks. Proposed channelization projects are reviewed for their effects on water quality and habitat. Preference is given to vegetative practices in evaluating permits for stabilization of shorelines and streambanks. To improve surface water quality and restore instream and riparian habitat in existing modified channels, the State is preparing watershed assessments for priority watersheds, which identify nonpoint sources causing the water quality impairments or threats to impairments. Landowners may enter into cost-share agreements on a voluntary basis to install and maintain practices designed to reduce nonpoint pollution resulting from activities on their land. Subsequent to the program submittal, Wisconsin provided additional information on how the State implements the erosion and sediment control and chemical and pollutant control management measures for dams. Under Chapter 31, Wisconsin Statutes, Wisconsin requires permits for the construction, enlargement, operation and maintenance of dams on navigable waterways. As described on page 10-9 of the program submittal, the Department of Natural Resources has "the authority to investigate and determine all reasonable methods of construction, operation, maintenance, and equipment for any dam so as to conserve and protect all public rights in navigable waters." Dams built on non-navigable waterways do not require permits, but still must be approved by the Wisconsin Department of Natural Resources. In supplemental material provided by the State, Wisconsin included a set of standard permit conditions that are used for dam approvals. This list of conditions includes a requirement for development and implementation of an erosion control plan. However, the list of conditions does not include management measures for chemical and pollutant control. In addition, though the list of conditions appears to be a standard set of requirements for dam permit approvals, NOAA and EPA encourage Wisconsin to further strengthen their program by codifying the standard set of conditions in rules. Wisconsin implements management measures to protect surface waters and habitat from the effects of dam operation by issuing permits to construct, operate and maintain dams in navigable waters, and determining whether the proposed activities will cause environmental pollution. Most elements of the management measure to protect shoreline features serving a nonpoint source abatement function are implemented through the State's statutory oversight of shoreland management ordinances, which establish standards for shoreline activities related to maintaining and improving water quality. However, the State does not have a process to identify and develop strategies to solve existing nonpoint source problems caused by streambank and shoreline erosion that do not come up for review under existing permit authorities. VII. WETLANDS, RIPARIAN AREAS, AND VEGETATED TREATMENT SYSTEMS FINDING: Wisconsin's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation. RATIONALE: The State requires permits for most alterations of navigable waters, including wetlands on the beds of navigable waters, and projects involving grading and filling within 500 feet of navigable waters. In addition, the State makes a determination of compliance with functional water quality standards for any proposed activity involving wetlands over which the State has jurisdiction and which has the potential to affect wetlands. This includes all regulatory, planning, management, and financial aid determinations involving wetlands. Wetland characteristics described in Wisconsin's water quality standards include nonpoint source functions such as storage and retention of runoff, filtration of sediment and chemical pollutants from surface waters, and habitat for aquatic organisms. Shoreland zoning requirements and the priority watershed program also help to implement management measures for activities upstream in the watershed which can affect the nonpoint source functions in wetlands and riparian areas. Management measures promoting restoration of wetlands and riparian areas are implemented through the State's cost-share program. The use of these practices is promoted in priority watersheds where the restored wetlands and riparian areas will serve a nonpoint pollution abatement function. The State also utilizes opportunities in the USDA Wetlands Reserve Program, and Agricultural Conservation Program, to promote restoration of wetlands and riparian areas. Management measures promoting the use of vegetated treatment systems are implemented through the State's cost-share program. The use of these practices is promoted in priority watersheds where the practices will serve a nonpoint pollution abatement function. The State also utilizes opportunities in the USDA Agricultural Conservation Program to promote treatment of runoff by vegetated treatment systems or by sedimentation ponds. VIII. ADMINISTRATIVE COORDINATION FINDING: Wisconsin's program establishes mechanisms to improve coordination among State agencies and between State and local officials. RATIONALE: Administrative coordination for the coastal nonpoint program will be achieved through memoranda of agreement and understanding describing specific agency roles and coordination. Interagency advisory committees and boards provide consultation and serve a policy-making role. The agencies involved in these agreements are the DNR, the DATCP, University of Wisconsin Extension and Cooperative Extension Service, U.S. Department of Agriculture Natural Resources Conservation Service and Consolidated Farm Services Agency, DILHR and WisDOT. On June 15, 1993 an interagency task force was established to assist the development of Wisconsin's coastal nonpoint program. The task force operates under the authorization of the Secretaries of Administration; Natural Resources; Transportation; Industry, Labor, and Human Relations; and Agriculture, Trade, and Consumer Protection. Within the task force work groups were established to evaluate the management measures with respect to Wisconsin's program and produce a series of recommendations regarding the adequacy of existing programs for management measure compliance. IX. PUBLIC PARTICIPATION FINDING: Wisconsin's program provides opportunities for public participation in the development and implementation of the coastal nonpoint program. RATIONALE: As described on pages 13-1 to 13-8 of the program submittal, Wisconsin's public participation activities have and will continue to provide opportunities for public education and input regarding the coastal nonpoint program. The State's activities include distribution of printed materials, publication of newsletter articles, production of teleconferences, and briefings of State legislators, agency officials, public advisory groups, and others. Wisconsin also provided a 30 day public review and comment period on the program. NOAA and EPA encourage Wisconsin to pursue the public participation activities described in section 13.2 of the program submittal. X. TECHNICAL ASSISTANCE FINDING: Wisconsin has included programs that will provide technical assistance to local governments and the public for implementing additional management measures. RATIONALE: Wisconsin has proposed a variety of technical assistance efforts for local governments and the public. These efforts will focus on numerous issues related to nonpoint source pollution activities. The assistance will be conducted by State, local and regional entities. Through the State's priority watershed program, the DNR will be able to identify areas that may require additional management measures and ensure that technical assistance is provided in order to ensure implementation. Examples of technical assistance include assistance in implementing forestry practices by DNR foresters and assistance in the area of marinas and recreational boating by the DNR Bureaus of Law Enforcement and Water Regulation and Zoning. Several State agencies and regional planning commissions will assist with technical assistance efforts in the area of hydromodification. XI. ADDITIONAL MANAGEMENT MEASURES FINDING: Wisconsin's program does not provide for the identification of additional management measures and the continuing revision of management measures applicable to critical coastal areas and cases where (g) measures are fully implemented but water quality threats or impairments persist. CONDITION: Within one year, Wisconsin will identify a process for determining whether additional measures are necessary to attain or maintain water quality standards in threatened or impaired waters. This process will include the identification of coastal waters that are not attaining or maintaining water quality standards, the identification of land uses causing or threatening water quality impairments, and identification of critical coastal areas. RATIONALE: While referring to zoning regulations and ordinances that broadly define critical coastal areas and citing Chapter NR 115, Wisconsin Administrative Code (Shoreland Management Program), Chapter NR 117, Wisconsin Administrative Code (City and Village Shoreland-Wetland Protection Program) and Chapter NR 121, Wisconsin Administrative Code (Areawide Water Quality Management Plans), Wisconsin's program does not describe a process for developing additional management measures. XII. CRITICAL COASTAL AREAS FINDING: Wisconsin's program identifies and includes a process for the continuing identification of critical coastal areas adjacent to impaired and threatened coastal waters. RATIONALE: As described in Chapter 12 of the program submittal, Wisconsin proposes to use its Shoreland Management Program (NR 115, Wis. Adm. Code) as the basis for designating critical coastal areas. Under NR 115, land within 1,000 feet of a lake, pond or flowage; and 300 feet from a river or stream or to the landward side of the flood plain, both from the ordinary high- water mark of navigable waters, qualify as regulated shorelands. Chapter NR 117 also establishes minimum standards for city and village shoreland-wetland zoning ordinances. XIII. MONITORING FINDING: Wisconsin'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, Wisconsin will include 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, Wisconsin provides an overview of its monitoring programs, but does not describe how these monitoring programs and techniques will be applied to assess over time whether the management measures are reducing pollution loads and improving water quality. The condition, problem assessment, and evaluation monitoring described by the State should be adaptable to the needs of section 6217, but Wisconsin has not yet identified specific monitoring efforts that it will apply to the coastal program. Wisconsin should include in its plan information regarding the number and location of monitoring stations, the types and frequency of water quality data being collected, and the analytic approaches that will be employed in conjunction with existing monitoring efforts to assess the success of management measures in achieving water quality objectives. The State should include some inexpensive tracking of management measure implementation in conjunction with water quality monitoring, as such information is needed to assess the success of management measures in achieving water quality objectives. XIV. STRATEGY AND EVALUATION FOR BACK-UP AUTHORITIES Within one year, Wisconsin will develop a strategy to implement the management measures for agriculture, forestry, new development, construction site chemical control, and marinas (solid waste, fish waste, liquid material, petroleum control, and boat cleaning), 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, Wisconsin 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.
