FINDINGS FOR THE MISSISSIPPI COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the State of Mississippi pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the Mississippi Coastal Nonpoint Program, Final Program Submittal, August 1995 and supplemental material provided by Mississippi 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 Mississippi 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 Mississippi 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 Mississippi's program. It also provides the rationale for the findings and includes conditions that will need to be met for Mississippi 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 Mississippi Coastal Nonpoint Program, Final Program Submittal, August 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 Mississippi 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: Chris Zabawa (202-260-7101) NOAA/Office of Ocean and Coastal Resource Management Coastal Programs Division SSMC-4, N/ORM3 1305 East-West Highway Silver Spring, MD 20910 Contact: Jewel Griffin (301-713-3109 Ext. 163) U.S. EPA, Region 4 61 Forsyth St., SW Atlanta, GA 30303 Contact: Robert B. Howard (404-562-9370) I. BOUNDARY FINDING: Mississippi's proposed 6217 management area is sufficient to control the land and water uses that have or are reasonably expected to have a significant impact on the State's coastal waters. RATIONALE: Mississippi proposes to modify the NOAA recommended 6217 management area by excluding the small portions which lie in Perry, Green and Wayne Counties. This modification results in the exclusion of 3% (or 125 square miles) of the NOAA recommended 6217 management area. According to the State's 1992 Section 305 (b) Water Quality Assessment Report and 1989 Section 319 Nonpoint Source Assessment Report, indicators of nonpoint source pollution have not been cited within the portions of the three counties proposed for exclusion. In addition, a majority of land use in the portions of the three counties proposed for exclusion is composed of public land and open land (which may include vacant or federally-owned forestry lands). Finally, the three counties within the proposed management area all have small populations, minimal residential, commercial and industrial development and land use activities, and limited access by public roadways. Therefore, NOAA and EPA agree that the State's proposed management area is sufficient to control the land and water uses that have or are reasonably expected to have a significant impact on the State's coastal waters. II. AGRICULTURE FINDING: Mississippi's program includes management measures in conformity with the 6217(g) guidance. The State has identified a backup enforceable policy and mechanism for the agricultural management measures, but has not yet demonstrated the ability of this authority to ensure implementation throughout the 6217 management area. Mississippi has provided sufficient justification for an exclusion of the irrigation water management measure, but has not provided sufficient justification for an exclusion of the grazing management measure. CONDITION: Within one year, Mississippi will develop a strategy (in accordance with Section XIV, page 15) to implement the agricultural management measures throughout the 6217 management area. RATIONALE: Mississippi proposes to implement the agricultural management measures through voluntary programs administered by the U.S. Department of Agriculture (USDA), local soil and water conservation districts, and State agencies such as the Department of Agriculture and Commerce. These programs include conservation plans developed by the USDA Natural Resources Conservation Service (NRCS) and conservation districts, nutrient management planning, Farm-A-Syst, and technical assistance from USDA. As described in supplemental information provided by the State subsequent to the program submittal, Mississippi will use practices from the NRCS Field Office Technical Guide to implement the agricultural management measures. The practices or combination of practices identified by the State in its supplemental material are in conformity with the 6217(g) management measures. On pages 159-160 of the program submittal, Mississippi identifies a number of options that the State is considering to further develop the agricultural component of the coastal nonpoint program. NOAA and EPA encourage Mississippi to pursue these options in order to ensure that State programs are implemented in conformity with the 6217(g) management measures. Mississippi cites the Mississippi Air and Water Pollution Control Law (Miss. Code, 49-17-1 to 49-17-43) as a backup enforceable policy and mechanism to ensure implementation of the agricultural management measures. This law states, in part, that "It shall be unlawful for any person (I) to cause pollution of any waters of the state or to place or cause to be placed any wastes in a location where they are likely to cause pollution of any waters of the state...." (49-17-29(2)(a)). The Department of Environmental Quality (DEQ) is authorized to impose penalties on anyone violating the law. Additional authority is provided under the Wastewater Permit regulations (for confined animal operations) and the Mississippi Pesticides Law (Miss. Code, 69-23-1 to 69- 23-27). The State, however, has not demonstrated how it will ensure implementation of the agricultural management measures using these programs and authorities. The Wastewater Permit regulations require a State permit for "all animal feedlots, Grade A dairies, poultry operations with 9,000 or more birds, swine operations with 10 or more sows or 50 or more swine, which have been constructed, enlarged, or significantly altered after August 15, 1979 or any other animal confinement causing pollution of the waters of the State." Facilities are required to submit an NRCS treatment design worksheet and have a site inspection prior to receiving a permit. DEQ also requires a waste management plan. However, the requirements in the regulations for containing all process wastewater and runoff from a 25-year, 24-hour rainfall event apply only to National Pollutant Discharge Elimination System (NPDES) permits, and not State permits. Irrigation in Mississippi's 6217 management area occurs on a small amount of land (approximately 750 acres). Mississippi estimates that 36% of the systems are sub-surface, low-volume trickle or sprinkler systems which do not produce significant amounts of runoff. Irrigation, therefore, does not and is not reasonably expected to present significant adverse effects to living coastal resources or human health. Mississippi requested an exclusion from the grazing management measure but supported this proposal by reporting only on the number of cattle per county. Total pastureland accounts for approximately 45% of all agricultural land in the 6217 management area. The State has not presented sufficient justification to indicate that nonpoint pollution from grazing does not and is not reasonably expected to have significant adverse effects on the coastal waters of Mississippi. III. FORESTRY FINDING: Mississippi has not provided sufficient justification to support a categorical exclusion of forestry from its coastal nonpoint program. CONDITION: Within three years, Mississippi will include in its program management measures for forestry in conformity with the 6217(g) guidance and enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. RATIONALE: In its current year section 305(b) report (Draft 1996) and section 319 nonpoint source assessment, Mississippi has identified waterbodies within Mississippi's 6217 management area that are impaired by forestry. These include 49 river miles (Murder Creek and Biloxi River) of the 427 river miles assessed and 2,464 river miles within the coastal management area. Water quality impacts from forestry activities include siltation, nutrients, pH, and pathogens. Mississippi has a commendable Best Management Practices Handbook (1989) which addresses many of the management measures. These include guidelines and specifications for streamside management areas, road construction, timber harvesting, site preparation, and revegetation. Approximately 55%, or 879,358 acres of the total 1.6 million acres of forest land, are owned by landowners who use Mississippi's forestry best management practices (BMPs). These landowners include the federal government, the State of Mississippi, county and municipal forestry lands managed by the State Forestry Commission, forestry industry owned lands, large family holdings and lands owned by pension funds while managed by licensed foresters, and non-industrial private landowners using government cost-share programs. While these figures are encouraging, broader use of Mississippi's forest BMPs is clearly needed. The forestry community in Mississippi has also participated in BMP education and logger training programs. In 1995 the Mississippi legislature funded the core elements of a logger education program at $108,000 annually to the Cooperative Extension Service beginning July 1, 1995. The forestry industry will fund an additional $150,000 annually to cover the on-site expenses necessary to conduct over 200 workshops necessary to reach the 1,000 logging contractors, their employees and industry foresters. These five day-long workshops will cover such topics as sustainable forestry principles, forestry best management practices, regeneration and forestry conservation. EPA and NOAA commend Mississippi for the use of best management practices and the new Logger Education Program funded by the legislature in 1995. However, Mississippi has not demonstrated that forestry sources do not present and are not reasonably expected to present significant adverse effects to Mississippi's coastal waters. Where there are existing programs that meet the management measures, we encourage Mississippi to include them in the coastal nonpoint program. IV. URBAN A. NEW DEVELOPMENT, WATERSHED PROTECTION, EXISTING DEVELOPMENT, and SITE DEVELOPMENT FINDING: Mississippi'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 these management measures, but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Mississippi will include in its program management measures for new development, watershed protection, existing development, and site development in conformity with the 6217(g) guidance. Within one year, Mississippi will develop a strategy (in accordance with Section XIV, page 15) to implement these management measures throughout the 6217 management area. RATIONALE: The State generally does not have programs in place that implement these management measures. On pages 29- 31 of the program submittal, the State presents several proposals for new activities that could potentially implement these management measures. One of the proposed activities is development of a State Comprehensive Urban Nonpoint Source Pollution Control Program. This program would seek assistance from local governments for the implementation of these management measures by linking education efforts, incentive- based programs, monitoring programs, and adoption of local ordinances. For the watershed protection management measure, the State presents several additional proposals, including amending its planning law to require local governments to address watershed planning. The State also suggests developing model ordinances, including a storm water ordinance, to help meet the existing development management measure. NOAA and EPA encourage the State to pursue these approaches to help achieve these management measures. The State identifies several authorities as enforceable policies and mechanisms to ensure implementation of these management measures, particularly the Mississippi Air and Water Pollution Control Law (see the agriculture section, above, for a discussion of this authority). The State, however, has not yet demonstrated that these authorities will ensure implementation of the management measures throughout the 6217 management area. B. CONSTRUCTION SITE EROSION AND SEDIMENT and CHEMICAL CONTROL FINDING: Mississippi's program does not include management measures in conformity with the 6217(g) guidance for construction site erosion and sediment control and chemical control. The State has identified back-up enforceable policies and mechanisms for these management measures, but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Mississippi will include in its program management measures for construction site erosion and sediment and chemical control in conformity with the 6217(g) guidance. Within one year, Mississippi will develop a strategy (in accordance with Section XIV, page 15) to implement these management measures throughout the 6217 management area. RATIONALE: In its program submittal, Mississippi states that it does not have any specific programs geared toward the prevention of nonpoint pollution from construction site activities. For construction site erosion and sediment control, the DEQ, in cooperation with the Mississippi Soil and Water Conservation Commission (MSWCC), and the NRCS, has developed the Planning and Design Manual for the Control of Erosion, Sediment and Stormwater (1994), which recommends the development of an erosion and sediment control plan and describes a number of practices that could be used to reduce erosion on construction sites. To achieve the construction erosion and sediment control management measure, the State proposes adopting a Comprehensive Urban Nonpoint Source Pollution Control Program and requiring development of erosion and sediment control plans. In addition, the State proposes developing a model sediment and erosion control ordinance. These proposals, particularly a State- level requirement for an erosion and sediment control plan, would provide a good basis for achieving the construction site erosion and sediment control management measure. In its program submittal, the State also proposes to develop a manual on best management practices for the use and control of petroleum products, pesticides, nutrients and solid wastes on construction sites. NOAA and EPA see the development of such a manual as a promising approach toward achieving the construction site chemical control management measure. The State identifies the Mississippi Air and Water Pollution Control Law as providing back-up enforcement authority to ensure implementation of these management measures (see the agriculture section, above, for a discussion of this authority). The State, however, has not yet demonstrated the ability of this authority to ensure implementation of the construction site erosion control and chemical control management measures. C. NEW AND OPERATING ONSITE DISPOSAL SYSTEMS FINDING: Mississippi's program includes management measures in conformity with the 6217(g) guidance, except the program does not include provisions for 1) denitrification where nitrogen-limited surface waters may be adversely affected by excess nitrogen loadings from OSDS; 2) inspection of onsite systems other than performance based systems; and 3) adequate separation distances between OSDS system components and groundwater that is closely hydrologically connected to surface waters. Mississippi's program includes enforceable policies and mechanisms to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Mississippi will include in its program provisions for: 1) denitrification where nitrogen-limited surface waters may be adversely affected by excess nitrogen loadings from OSDS; 2) inspection of onsite systems other than performance based systems; and 3) adequate separation distances between OSDS system components and groundwater that is closely hydrologically connected to surface waters. RATIONALE: In July, 1996, the State's newly passed "Mississippi Individual On-Site Wastewater Disposal System Law" (Miss. Code, 41-67-1 to 41-67-31) took effect. This law includes provisions requiring the State Board of Health to adopt rules governing the design, construction or installation, and operation and maintenance (including performance standards) of onsite disposal systems for single family residential generators. The law also provides the State Department of Health with the authority to make inspections of systems; provides the State Department and Board of Health with authority to require property owners to repair malfunctioning systems; and allows local governments to adopt similar or more restrictive ordinances governing systems. In addition, the law provides for the imposition of penalties when onsite systems do not operate in accordance with the law or any regulations the State issues under the law. Subsequent to the program submittal, Mississippi provided NOAA and EPA with a copy of the revised Sanitation Regulations and Policies, Regulation 2.0 Individual Onsite Wastewater Disposal, promulgated under the new law. The revised regulations address factors such as slope, depth to groundwater, soil type, proximity to groundwater, sensitive waters, and dwellings, and site suitability. However, as currently written, the regulations do not provide for adequate separation distances between OSDS system components and groundwater that is closely hydrologically connected to surface waters. Though separation distance is based on soil type, the minimum of 12 inches for soils that contain a restrictive horizon is not adequate to protect groundwater that is closely hydrologically connected to surface water. The Mississippi State Department of Health (MSDH) does specify several categories of systems, including design based systems, performance based systems and experimental systems. Final system selection is determined by the homeowner, but a professional engineer must then be engaged to oversee the design, construction and installation of the OSDS. The engineer must also notify the County Health Department regarding any system(s) that he/she is contracted to design, construct or install. Persons actually installing the systems must be certified under a State administered program. In addition to revising current guidelines for separation distance, Mississippi may wish to consider requiring the use of performance based systems in instances where increased separation distances cannot be met. Though Mississippi requires that performance based systems be monitored and authorized on an annual basis, there are no similar requirements for design based systems to ensure that they are inspected at a frequency adequate to ascertain system failure. The State also does not specifically address the use of de-nitrification where conditions indicate that nitrogen-limited surface waters may be adversely affected by excess nitrogen loadings from groundwater. NOAA and EPA encourage Mississippi to make further progress in addressing these issues but also applaud the State for its recent improvements in the management of OSDS. D. POLLUTION PREVENTION FINDING: Mississippi's program includes management measures in conformity with the 6217(g) guidance. RATIONALE: Mississippi describes a number of existing programs and activities that address components of this management measure, including the State's Adopt-A-Stream program, a storm drain stenciling program, "amnesty days" for household hazardous wastes, coastal beach clean-ups, and a marine debris program. The State has proposed several additional projects, including the development of educational materials on the proper use of lawn chemicals and expansion of the storm drain stenciling program to other counties. We encourage the State to continue to build upon these pollution prevention efforts. E. ROADS, HIGHWAYS, AND BRIDGES FINDING: Mississippi's program does not include management measures in conformity with the 6217(g) guidance for roads, highways, and bridges. Mississippi has identified a backup enforceable policy and mechanism for the roads, highways, and bridges management measures, but has not yet demonstrated the ability of this authority to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Mississippi will include in its program management measures in conformity with the 6217(g) guidance for roads, highways, and bridges. Within one year, Mississippi will develop a strategy (in accordance with Section XIV, page 15) to implement the roads, highways, and bridges management measures throughout the 6217 management area. RATIONALE: The Mississippi Department of Environment Quality issues General NPDES storm water permits for Mississippi Department of Transportation (MDOT) construction activities on sites disturbing five acres or more. MDOT's program includes protective practices such as setbacks from wetlands, avoidance of wetlands, environmental quality reviews of proposed projects, inspection surveys, vegetation repair, herbicide minimization, and debris removal, but does not address the runoff systems management measure. For road, highway and bridge construction projects that disturb five acres or more of land and are permitted under NPDES, section 6217 does not apply. For roads, highways and bridges outside the jurisdiction of MDOT (sites involving disturbance of less than five acres, State Aid Roadways and county and city roadways) the State's program does not include management measures in conformity with the 6217(g) guidance. The State's Planning and Design Manual for the Control of Erosion, Sediment and Storm Water (developed by the State Department of Environmental Quality, in cooperation with MSWCC and NRCS), however, will assist in implementing the planning, siting, and development and construction site management measures. In its program submittal, the State proposes several possible approaches toward fully meeting the roads, highways and bridges management measures, including the development of standards for secondary roadways that can be used as models for local ordinances; development of educational materials and workshops; and revision of the Mississippi Coastal Program guidelines to be in conformity with these management measures. In its program submittal, the State identified the Air and Water Pollution Control Law as a backup enforceable policy and mechanism, but the State has not demonstrated that the authority will ensure implementation of the roads, highways and bridges management measures (see the agriculture section, above, for a discussion of this authority). Mississippi has also proposed to use the Clean Water Act Section 401 State certification process as additional enforcement authority; however, there are limitations in the way that section 401 certification can be used for the purposes of implementing the roads, highways and bridges measures. First, by its terms, 401 applies only to Federally licensed or permitted activities. Second, 401 applies only to "discharges" and relies on water quality standards - Mississippi may not have developed water quality standards for the full range of nonpoint source pollutants associated with roads, highway and bridges. Finally, 401 primarily relies on action by the Federal permitting authority to ensure compliance. Whether the 401 certification process can be used to enforce a particular State policy, and thus ensure implementation of a particular management measure, depends on the way that State water quality standards and other applicable requirements of State law are interpreted, as well as the State's ability to monitor and enforce against Federal permittees who violate the permit conditions. V. MARINAS AND RECREATIONAL BOATING A. SITING AND DESIGN FINDING: Mississippi's program includes management measures in conformity with the 6217(g) guidance. Mississippi's program includes enforceable policies and mechanisms to ensure implementation in a substantial portion of the 6217 management area, and the State has identified a backup enforceable policy and mechanism to ensure implementation in remaining portions of the 6217 management area. CONDITION: Within one year, Mississippi will develop a strategy (in accordance with Section XIV, page 15) to implement the marina siting and design management measures throughout the 6217 management area. RATIONALE: The Department of Marine Resources (DMR) is the State agency responsible for administering the Coastal Wetlands Protection Act (Miss. Code 49-27-1 to 49-27-69). Applications for new and expanding marinas are made to the DMR and are subject to Coastal Wetlands Permit program requirements. The Coastal Wetlands Permit program requires detailed information in conformity with all of the 6217(g) management measures for projects under its jurisdiction, except storm water runoff and fueling station design. Subsequent to the program submittal, Mississippi provided additional information on criteria that are used to evaluate marinas siting and design. The Freshwater and Coastal Marina Guidelines include management measures for storm water runoff and fueling station design. As described in the program submittal, there are some limitations in the jurisdiction of the Coastal Wetlands Permit program and Mississippi Coastal Program that may limit the ability of the State to address upland activities associated with marinas that impact coastal waters. Further, the Coastal Wetlands Protection Act defines coastal wetlands as publicly owned lands only and exemptions in the permit requirements may preclude the State from fully implementing the management measures for marina siting and design. Subsequent to the program submittal, Mississippi provided supplemental information that further describes how the State uses its water quality standards as a back- up authority, including the use of 401 certification of Federally issued permits. As described above under the roads, highways and bridges management measures, there are limitations in the way that this authority can be used and Mississippi has not yet demonstrated that its back-up water quality authority can ensure implementation. Mississippi has proposed to strengthen the linkage between the regulatory activities of the DEQ's 401 certification process and the DMR's Coastal Permit program by establishing a Memorandum of Understanding (MOU) between the two agencies. This MOU could be an integral part of the strategy described in the condition above. As described on page 213 of the program submittal, DMR is proposing to develop new and expanded performance standards and guidelines for regulating marinas to ensure that the State's management measures for marina siting and design are fully consistent with all 6217(g) management measures, including the measures for storm water runoff and fueling station design. NOAA and EPA support this proposal and encourage the State to incorporate the new marina regulations into the Mississippi Coastal Program to further strengthen the State's ability to ensure the proper siting and design of marina facilities. B. OPERATION AND MAINTENANCE FINDING: Mississippi's program does not include management measures in conformity with the 6217(g) guidance for the operation and maintenance of marinas and boats. The State has identified a backup enforceable policy and mechanism, but has not yet demonstrated the ability of this authority to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Mississippi will include in its program management measures for operation and maintenance in conformity with the 6217(g) guidance. Within one year, Mississippi will develop a strategy (in accordance with section XIV, page 15) to implement the operation and maintenance management measures throughout the 6217 management area. RATIONALE: As described on page 220 of the program submittal, Mississippi's program does not include management measures or specific enforceable policies and mechanisms for the marina operation and maintenance management measures. The State has identified its Air and Water Pollution Control Law, which prohibits any person to cause pollution of any waters of the State or to place or cause to be placed any wastes in a location where they are likely to cause pollution, as providing backup authority for the operation and maintenance management measures. The State, however, has not yet demonstrated the ability of this authority to ensure implementation of the operation and maintenance management measures. The State's program includes a proposed strategy to address the marina operation and maintenance management measures through a voluntary "managed marina" approach to include an education and enforcement program, a harbormaster training program, and implementation guidance. This approach, in conjunction with proposed MOU's between DMR and the Department of Environmental Quality to help ensure program implementation, can provide effective tools to help promote implementation of the operation and maintenance management measures. VI. HYDROMODIFICATION FINDING: Mississippi's program includes management measures in conformity with the 6217(g) guidance, and includes enforceable policies and mechanisms to ensure implementation of the management measures, except the State's program does not include: (1) a process to improve surface water quality and restore instream and riparian habitat through the operation and maintenance of existing modified channels; (2) management measures for erosion and sediment control at dams; (3) management measures for chemical and pollutant control at dams; (4) a process to identify and develop strategies to solve existing nonpoint source problems caused by streambank or shoreline erosion that do not come up for review under existing permit authorities; and (5) a process to protect shorelines against erosion due to uses of the adjacent shorelands. Mississippi has identified backup enforceable policies and mechanisms for the management measures for erosion and sediment control at dams and for the management measures for chemical and pollutant control at dams, but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Mississippi will include in its program management measures that are in conformity with the 6217 (g) management measures for improving surface water quality and restoring instream and riparian habitat through the operation and maintenance of existing modified channels, erosion and sediment control at dams, chemical and pollutant control at dams, solving existing nonpoint source problems caused by streambank or shoreline erosion that do not come up for review under existing permit authorities, and protecting shorelines from erosion. Within three years, Mississippi will include in its program enforceable policies and mechanisms for channelization, channel modification and shorelines and streambanks to ensure implementation throughout the 6217 management area. Within one year, Mississippi will develop a strategy (in accordance with Section XIV, page 15) to implement the management measures for erosion and sediment control and chemical and pollutant control at dams throughout the 6217 management area. RATIONALE: Mississippi requires permits for both new channelization activities and modification of existing channels. Permit applications for projects are reviewed for impacts on water quality, habitat, and the functions of wetlands as nonpoint source pollution filters. The State has authority in the permits to require best management practices which preserve and/or improve water quality of channelization and channel modification activities. The State's program does not contain a process to identify opportunities to improve surface water quality and restore instream and riparian habitat through operation and maintenance of existing modified channels. Mississippi's program does not contain management measures for erosion and sediment control, or for chemical and pollutant control at dams. While identifying backup enforceable policies and mechanisms for the management measures for erosion and sediment control at dams, and for chemical and pollutant control at dams, Mississippi has not yet demonstrated the ability of these authorities to ensure implementation of these management measures throughout the 6217 management area. Mississippi implements management measures for protection of surface water quality and habitat from the effects of dam operation by adding conditions to permits for dam construction, modification, and repair that are necessary to ensure that criteria and standards for downstream riparian and other beneficial water uses are met and maintained during dam operation. To implement management measures for eroding shorelines and streambanks, Mississippi requires permits for projects involving shoreline or streambank stabilization. The State has guidance on the development of shoreline stabilization projects which gives preference to vegetative solutions for shoreline and streambank erosion. Management measures to protect streambank and shoreline features with the potential to reduce nonpoint source pollution are also implemented through the State's forestry program, which promotes streamside management zones of vegetated buffers, and through local floodplain ordinances, which can implement setbacks from rivers and streams. However, the State's program does not have a process to identify and develop strategies to solve existing nonpoint problems caused by streambank or shoreline erosion that do not come up for review under existing permit authorities. VII. WETLANDS, RIPARIAN AREAS AND VEGETATED TREATMENT SYSTEMS FINDING: Mississippi's program includes management measures in conformity with the 6217(g) guidance, except that the program only addresses a limited number of activities and effects in conjunction with proposals for new work within wetlands and riparian areas. The program includes enforceable policies and mechanisms to ensure implementation, except there are exemptions and limitations in the geographic coverage of its existing permit authorities. Mississippi has identified a back-up enforceable policy and mechanism to ensure implementation for areas outside the jurisdiction of its current permit authorities, but has not yet demonstrated the ability of this authority to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Mississippi will include in its program management measures in conformity with the 6217(g) guidance to address activities affecting wetlands and riparian areas that are not currently reviewed under existing permit authorities. Within one year, Mississippi will develop a strategy (in accordance with Section XIV, page 15) to implement these management measures throughout the 6217 management area. RATIONALE: Mississippi requires a permit for dredging or filling activities in publicly owned tidal wetlands. Proposals for new work in publicly owned tidal wetlands are reviewed for their impacts on water quality, habitat, and the functions of wetlands as nonpoint source pollution filters. The Mississippi Coastal Wetlands Protection Act allows for limited control over the impacts on tidal wetlands from proposed development in upland areas. Subsequent to the program submittal, Mississippi provided supplemental information describing how, while certain activities may be excluded from the requirement to secure a permit under Section 2, Part II.A of the Mississippi Coastal Program, the DMR still requires a coastal program consistency certification (under Section 2, Part II.D) to ensure that state and Federal projects within the coastal zone are consistent with the Mississippi Coastal Program. According to the supplemental information, the DMR can initiate enforcement proceedings against excluded activities that violate the policies of the Mississippi Coastal Wetlands Program, however, Mississippi has not demonstrated that this authority can be used to implement the management measure for protection of wetlands and riparian areas. In addition, Mississippi has not demonstrated that existing authorities can be used to ensure implementation in non-coastal wetlands and riparian areas that may serve a significant nonpoint source abatement function. Management measures promoting restoration of wetland and riparian areas are implemented through the State's wetlands program, which requires restoration or mitigation of wetlands loss or degradation. Management measures promoting vegetative treatment systems are implemented through the State's agricultural cost-share program, and the Mississippi Forestry Commission, which promote filter strips and streamside management zones. The State's BMP manuals for silviculture, erosion and sediment control, and stormwater management also promote the application of vegetative BMPs. The planting of native wetland species is encouraged to stabilize retention ponds and to assimilate pollutants. VIII. ADMINISTRATIVE COORDINATION FINDING: Mississippi's program establishes mechanisms to improve coordination among State agencies and between State and local officials. RATIONALE: Several efforts have been initiated, or are planned, to strengthen coordination among State agencies and between State and local officials. These include several category-specific work groups and a state-wide task force (e.g., Mississippi Gulf Coast Environmental and Economic Interagency Council). In addition, Mississippi established a Coastal Water Quality Advisory Group to assist in policy development and implementation strategies. A Memorandum of Understanding will be developed between the lead coordinating agencies (Mississippi's Department of Marine Resources and Department of Environmental Quality). NOAA and EPA encourage the State to clarify the roles of State agencies (identified on pages 16-17 in the program submittal) in the implementation of the coastal nonpoint program. IX. PUBLIC PARTICIPATION FINDING: Mississippi's program provides opportunities for public participation in the development and implementation of the coastal nonpoint program. RATIONALE: Mississippi's coastal nonpoint program describes many activities that provide opportunities for public participation in the development and implementation of its coastal nonpoint program. The State established a series of working groups, including subcommittees on forestry, agriculture, urban and marinas in order to receive public input into program development. Each subcommittee included members from the general public and various State or local coordinating agencies. The State provided a 30-day public comment period on the final program submittal. Comments received by the State during its public hearing and subsequent public review were included in Volume III of the program submittal. X. TECHNICAL ASSISTANCE FINDING: Mississippi has included programs that will provide technical assistance to local governments and the public for implementing additional management measures. RATIONALE: Mississippi identified a variety of technical assistance initiatives available to local governments and the public. The assistance, offered by various ad hoc committees and State agencies for each of the proposed source categories, is described on pages 282-284 in the program submittal. XI. ADDITIONAL MANAGEMENT MEASURES FINDING: Mississippi's program provides for implementation and continuing revision of additional management measures applicable to critical coastal areas and cases where section 6217 (g) measures are fully implemented but water quality threats or impairments persist. RATIONALE: Mississippi's description of its process for the implementation of additional management measures includes an evaluation of priority watersheds identified in its 305 (b) Assessment Report to determine a correlation between 6217(g) measures and improved water quality. The State will evaluate all of its basins to determine the results of 6217(g) measure implementation through water quality monitoring. Based on these evaluations, appropriate additional management measures, if required, will be developed and implemented on a site-specific basis. This process generally follows the second approach described in the coastal nonpoint program guidance whereby the State relies on site-specific evaluations to determine whether additional management measures are required. XII. CRITICAL COASTAL AREAS FINDING: Mississippi's program identifies and includes a process for the continuing identification of critical coastal areas adjacent to impaired and threatened coastal waters. RATIONALE: Mississippi identified a process for identifying critical coastal areas in a document entitled "Mississippi Critical Coastal Analysis" provided subsequent to the program submittal. Mississippi will utilize its 1992 Water Quality Assessment Report and 1989 Nonpoint Source Assessment Report to evaluate and identify critical coastal areas. The Assessment Reports utilized a watershed approach to identify priority watersheds located within or immediately adjacent to coastal municipalities. The major source of nonpoint source pollution within the program's management area is urban sources, with pathogens and nutrients from failed septic systems and overburdened municipal wastewater treatment facilities cited as the major contributors. Where implementation of (g) measures in these areas fails to achieve water quality goals, Mississippi will implement additional management measures. XIII. MONITORING FINDING: Mississippi'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, Mississippi will include in its program a plan that enables the State to assess over time the extent to which implementation of management measures is reducing pollution loads and improving water quality. RATIONALE: As described on page 307 of the program submittal, Mississippi plans to develop and refine its monitoring efforts during its conditional approval period. The State's proposed strategy for developing the monitoring program is consistent with the monitoring needs for section 6217. Mississippi 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 OF BACKUP AUTHORITIES Within one year, Mississippi will develop a strategy to implement the management measures for agriculture, new development, watershed protection, existing development, site development, construction site erosion and sediment control, construction site chemical control, roads, highways and bridges, marinas and recreational boating, hydromodification, and wetlands and riparian areas throughout the 6217 management area. This strategy will include a description and schedule for the specific steps the State will take to ensure implementation of the management measure; describe how existing or new authorities can be used to ensure implementation where voluntary efforts are unsuccessful; and identify measurable results which, if achieved, will demonstrate the State's ability to achieve implementation of the management measure using the described approach. Mississippi 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.
