FINDINGS FOR THE MASSACHUSETTS COASTAL NONPOINT PROGRAM FOREWORD This document contains the findings for the coastal nonpoint pollution control program submitted by the Commonwealth of Massachusetts pursuant to Section 6217(a) of the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA). The findings are based on a review of the Massachusetts Coastal Nonpoint Program, Final Program Submittal, July 1995 and supplemental material provided by Massachusetts 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 Massachusetts 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 Commonwealth of Massachusetts 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 the Commonwealth's program. It also provides the rationale for the findings and includes conditions that will need to be met for Massachusetts to receive final approval of its program. We recognize that Massachusetts has already proposed some changes to its program that would, if finalized, ensure implementation of the management measures in conformity with the section 6217(g) guidance. In these cases, the conditions are based on the Commonwealth's proposed changes. The timeframes associated with conditions become effective on the date of the approval letter for these findings. INTRODUCTION This document is organized by the major nonpoint source categories and subcategories identified in the section 6217(g) guidance and the administrative elements identified in the program guidance (including the boundary for the 6217 management area). Where appropriate, NOAA and EPA have grouped categories and subcategories of management measures into a single finding. The structure of each finding follows a standard format. Generally, the finding is that the state program includes or does not include management measures in conformity with the (g) guidance and includes or does not include enforceable policies and mechanisms to ensure implementation. In some cases, the finding reflects that the state has identified a back-up enforceable policy, but has not yet demonstrated the ability of the authority to ensure implementation. For further understanding of terms in this document, the reader is referred to the following: Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters (EPA, January 1993) Coastal Nonpoint Pollution Control Program: Program Development and Approval Guidance (NOAA and EPA, January 1993) Flexibility for State Coastal Nonpoint Programs (NOAA and EPA, March 1995) The references in this document refer to the Massachusetts 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 Commonwealth has included in its program submittal. Further information and analysis, including material provided by Massachusetts 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 Street, S.W.

BOUNDARY FINDING: Massachusetts has expanded the management area recommended by NOAA and EPA to include the Nashua and Concord River watersheds which drain to the Merrimack River. The Commonwealth's boundary is sufficient to control the land and water uses that have or are reasonably expected to have a significant impact on the coastal waters of Massachusetts. II. AGRICULTURE FINDING: Massachusetts' program includes management measures in conformity with the 6217(g) guidance. Massachusetts has identified back-up enforceable policies and mechanisms for implementing the agricultural management measures and has developed a strategy for implementation but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within three years, Massachusetts will demonstrate its ability to achieve implementation of the agricultural management measures using the approach described in its coastal nonpoint program strategy for agriculture (see Section III.1.3 pages 98-100 of the program submittal). Within one year, the Commonwealth will identify measurable results to be achieved during this three year timeframe. RATIONALE: Existing programs for agriculture in Massachusetts are largely voluntary, but the Commonwealth has identified a back-up enforceable authority through its Surface Water Quality Standards, and has additional authorities under the Pesticide Control Act and Wetlands Protection Act. The Commonwealth will rely on the general authority contained in the Surface Water Quality Standards (314 CMR 4.00) in combination with its voluntary programs to implement the agricultural management measures. Massachusetts has stated that it will work to establish interim implementation goals to define measurable progress, and that it will evaluate the need for additional control mechanisms after three years. Massachusetts has described how it will use its voluntary programs to achieve management measure implementation. The farm planning model described on page 93 of the program submittal will be used in combination with U.S. Department of Agriculture (USDA) conservation plans. Technical guidance will contain performance standards in conformity with the measures and practices in the section 6217(g) guidance. The Commonwealth has also described how it will apply the Basin Planning Approach and Surface Water Quality Standards to require implementation of farm plans in cases where water quality violations persist. To strengthen its voluntary approach, Massachusetts is encouraged to develop and implement the Commonwealth's farm planning model and technical assistance program, and work with USDA in its development and implementation of conservation plans, in a manner that ensures that all applicable management measures are fully implemented on farms in the 6217 management area. While the program submittal discussed each of the elements of the section 6217(g) management measures for agriculture, some elements were not fully detailed. The submittal did not specify that the components of the Nutrient Management Program include a written nutrient management plan and nutrient application rates based upon realistic yield expectations, but in subsequent discussions with Massachusetts Coastal Zone Management staff, the Commonwealth informed EPA and NOAA that this is the case. Massachusetts should ensure that these aspects of the nutrient management measure are fully addressed in program implementation. Where irrigation is practiced in Massachusetts, the measurement of both crop water needs and quantity of water applied to crops should be addressed as the key elements of the irrigation management measure. III. FORESTRY FINDING: Massachusetts includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation. RATIONALE: Massachusetts has a Forest Cutting Practices Act (FCPA) that contains the primary mechanisms for implementing the forestry management measures. Requirements and standards governing operations related to forest cutting, as well as references to standards in the Massachusetts Forestry Best Management Practices (BMP) Manual, are expressly contained in the FCPA (3.04 CMR 11.00 et seq.). Other enforceable policies and mechanisms the Commonwealth uses to implement forestry management measures include the Wetlands Protection Act (MGL c.131 s.40), the Slash Law (MGL c.48 ss16-16A), and the Pesticide Control Act (MGL c. 132B). IV. URBAN RUNOFF A. NEW DEVELOPMENT FINDING: Massachusetts' program does not yet contain management measures in conformity with the 6217(g) guidance. Massachusetts has identified back-up enforceable policies and mechanisms for implementing the management measure but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within two years, Massachusetts will finalize the proposed Stormwater Management Performance Standards. Within three years, Massachusetts will demonstrate its ability to achieve implementation of the new development management measure using the approach described in its coastal nonpoint program strategy for the Stormwater Initiative (see Section III.3.4 pages 173-176 of the program submittal). Within one year, the Commonwealth will identify measurable results to be achieved during this three year timeframe. RATIONALE: The Massachusetts Department of Environmental Protection (DEP), in coordination with the Massachusetts Coastal Zone Management (MCZM) Office, has proposed Stormwater Management Performance Standards which will meet the requirements of this management measure. The proposed Performance Standards address a number of areas, including the avoidance of direct stormwater discharges to surface waters and wetlands; managing increases in peak flood rates and elevations; control of post-development runoff volumes; control of total suspended solids (TSS); and operation and maintenance for stormwater facilities. Specifically, the Performance Standards will require that post-development peak discharge rates not exceed pre- development peak discharge rates for 2- and 10-year storm events, and that 80 percent TSS be removed on an average annual basis. The Commonwealth is also developing an accompanying guidance document, Performance Standards and Guidelines for Stormwater Management in Massachusetts to explain the Performance Standards, establish design criteria, identify management practices to achieve the Standards, and provide technical and regulatory guidance. As described on pages 173-176 of the program submittal and further detailed in draft Policy/Regulatory Guidance developed by the Stormwater Advisory Committee, Policy Subcommittee (provided to NOAA and EPA subsequent to the program submittal), the stormwater performance standards are designed for use under multiple statutory and regulatory authorities of the DEP. The Commonwealth proposes to use the regulatory review processes of the Wetlands Protection Act (MGL c.131 s.40) and its regulations (310 CMR 10.00) as one of the primary means to ensure implementation of the performance standards. Technical guidance (developed by the Commonwealth as part of the Stormwater Initiative and described above) will be provided to each of the local Conservation Commissions, which will use the performance standards in review of any wetlands permitting activity. Because of the broad jurisdiction exercised by Conservation Commissions and the DEP under the Wetlands Protection Act, Massachusetts proposes that the Commonwealth has the ability to ensure implementation of this management measure. B. WATERSHED PROTECTION AND EXISTING DEVELOPMENT FINDING: Massachusetts' program includes management measures in conformity with the 6217(g) guidance, except for watershed protection, and includes enforceable policies and mechanisms that can be used to ensure implementation. CONDITION: Within two years, Massachusetts will complete development of the "Soil and Water Conservation in Urbanizing Areas of Massachusetts" guidance document. RATIONALE: Massachusetts proposes to use a variety of programs to implement the watershed protection management measure. As described for the construction site erosion management measure below, the Commonwealth is developing guidelines for soil and water conservation in urbanizing areas that can accomplish protection of erosion-prone soils. As described on page 176 of the program submittal, this new technical guidance, entitled "Soil and Water Conservation in Urbanizing Areas of Massachusetts," will be integrated into both Commonwealth and local level planning and resource protection programs. The environmental evaluation program under the Massachusetts Environmental Policy Act (MEPA)(MGL c. 30, ss. 61-62H), which calls for the review of the impacts of certain large-scale projects on aquatic resources, and the Watershed Protection Act, which calls for the implementation of comprehensive watershed protection plans for drinking water supplies, will also be used to preserve areas that provide important water quality benefits. Massachusetts needs to complete development of the guidance document to provide the technical basis for implementing watershed protection. The Commonwealth's Watershed Initiative, which establishes a model framework to involve stakeholders in the development and implementation of watershed action plans, includes a multi-year process that will ultimately be implemented in each of the Commonwealth's twenty-seven river basins and drainage areas. This initiative involves a watershed resource assessment and outreach effort; water quality and quantity and habitat inventory; an assessment of collected data to identify basic objectives and preliminary results; development of management goals for water quality, including point and nonpoint sources; identification of watershed protection and restoration goals, and; an evaluation of results to determine progress and identify next steps. A schedule for implementing this new watershed approach is provided in Appendix G of the program submittal. This effort is to be commended and provides a framework for implementing the existing development management measure. We encourage the Commonwealth to further strengthen implementation of the above programs and ensure that, together, they provide a comprehensive approach to achieving the watershed protection and existing development management measures. We also applaud the Commonwealth for recently adopting river protection legislation that will create riparian buffer zones to protect water quality supplies and fisheries and wildlife habitat and prevent polluted runoff. This will further assist the Commonwealth in achieving the measures. C. SITE DEVELOPMENT, CONSTRUCTION SITE EROSION AND SEDIMENT CONTROL, and CONSTRUCTION SITE CHEMICAL CONTROL FINDING: Massachusetts' program does not yet contain management measures in conformity with the 6217(g) guidance, but includes enforceable policies and mechanisms to ensure implementation. CONDITION: Within two years, Massachusetts will finalize and adopt the proposed revisions to its State Building Code (780CMR) as outlined in the program submittal (see Section II.C.). RATIONALE: The Commonwealth has proposed to revise the State Building Code to meet these management measures. Under the Building Code, all new development is subject to review by local building inspectors. As described on page 182 of the program submittal, specific language in the Building Code will require the use of best management practices to prevent unnecessary soil disturbance, offsite sediment movement, and water quality degradation from the improper storage, use, or disposal of construction chemicals. In support of the proposed revisions to the Building Code, MCZM plans to provide technical assistance targeted to local officials to more effectively implement these management measures. The Commonwealth will also adopt new technical guidance entitled "Soil and Water Conservation in Urbanizing Areas of Massachusetts" as an official Commonwealth document and reference it in the Building Code. D. NEW AND OPERATING ONSITE DISPOSAL SYSTEMS (OSDS) FINDING: Massachusetts' program includes management measures in conformity with the 6217(g) guidance and enforceable policies and mechanisms to ensure implementation. RATIONALE: The siting, design, installation, and operation of new and operating OSDS is regulated by DEP through its Groundwater Discharge Program (MGL Ch. 221A, s.13). DEP has promulgated regulations under 310 CMR 15.00 Title 5 of the State Environmental Code. The Commonwealth recently revised the Code (effective at the end of March 1995). The revisions significantly improve the Code, providing comprehensive requirements that meet both the new and operating OSDS management measures. E. POLLUTION PREVENTION FINDING: Massachusetts' program contains management measures in conformity with the 6217(g) guidance. RATIONALE: In its program submittal, the Commonwealth describes a number of programs and efforts in place in the Commonwealth that cover all aspects of this management measure. These programs and efforts include the Municipal Household Hazardous Waste Program, the Save the Bay Program, the Massachusetts Bay Program, the Groundwater Discharge Program, the Massachusetts Adopt-A-Stream program, and various education and outreach efforts. F. ROADS, HIGHWAYS, AND BRIDGES FINDING: Massachusetts' program does not yet include management measures for roads, highways, and bridges in conformity with the 6217(g) guidance. The Commonwealth has identified back-up enforceable policies and mechanisms for implementing the management measures and has developed a strategy for implementation but has not yet demonstrated the ability of these authorities to ensure implementation throughout the 6217 management area. CONDITION: Within two years, Massachusetts will complete and implement the strategy for roads, highways, and bridges described in items 1-6 on pages 201 and 202 of the program submittal. RATIONALE: Massachusetts has proposed to complete the development of an environmental specifications manual that can be used in concert with the existing design manual of the Massachusetts Highway Department (MHD). In addition, implementation of DEP's Stormwater Initiative will establish a basis for project controls at the local level. Completion of the DEP urban stormwater guidance and the MHD specifications guidance will provide the technical basis for ensuring that projects are implemented in accordance with the 6217(g) management measures. MEPA, the Wetlands Protection Program, the Stormwater Initiative, the Hazardous Material Control Program, and the Clean State Executive Order (#350) provide the means to implement these management measures. Massachusetts has proposed to develop explicit policies to clarify the relative responsibilities of State and local agencies where their jurisdiction and authority intersect. MHD manages both construction and operation and maintenance contracts and has the ability to write specific environmental controls into those contracts. The MEPA review process requires environmental review and certification for larger land disturbances and road designs, but does not ensure that management measures are implemented for smaller projects. The Commonwealth has proposed to examine MEPA thresholds and consider a standard based on impervious cover in order to evaluate the negative impacts of surface water runoff for roads, highways and bridges. V. MARINAS AND RECREATIONAL BOATING FINDING: Massachusetts' program does not yet include management measures in conformity with the 6217(g) guidance but includes enforceable policies and mechanisms that can be used to ensure implementation. CONDITION: Within two years, Massachusetts will finalize the development of technical guidance to provide agency staff with information necessary to make consistent and effective permit and enforcement decisions. RATIONALE: The Massachusetts Chapter 91 Waterways Program (Massachusetts General Laws, Chapter 91) and regulations (310 CMR 9.00), along with the Wetlands Protection Act and other environmental and planning programs, can be used to ensure the implementation of the marina management measures as specified in the 6217(g) guidance. The Chapter 91 Waterways Program provides that jurisdictional activities must comply with any and all applicable environmental laws of the Commonwealth. However, specific nonpoint source controls that may be required by these authorities are not always clearly identified and the Waterways Program currently does not have a set of standard marina management measures that are used in permitting decisions. The Commonwealth recognizes this limitation and is proposing to develop guidance documents that will be used in the review of permit applications for new and expanding marina developments, including requirements for stormwater management. As stated in on page 242 of the program submittal, the proposed guidance document will provide the technical basis for determining compliance and, if needed, enforcement actions by DEP. The establishment of a uniform and predictable protocol (through the guidance document for marinas and recreational boating), linked with the existing permitting programs, will provide Massachusetts with a program that can meet the 6217(g) management measures. VI. HYDROMODIFICATION FINDING: Massachusetts' program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation. RATIONALE: Massachusetts requires a permit for new fill or structures and dredging in channels. To receive a Chapter 91 Waterways Permit, regulations require that projects not cause or contribute to erosion, sedimentation, inadequate flushing, stagnancy, interference with anadromous fish runs, or the degradation of aquatic habitat. Projects involving channelization of more than 2,000 feet of waterway, or dredging more than 500 feet of waterway, also undergo a formal comprehensive review process under MEPA. The Commonwealth's Waterways Program has been expanded to identify and implement projects that restore water quality and aquatic habitat in existing modified channels. Massachusetts regulates construction of new dams and alteration or repair of existing dams. To obtain a permit, erosion and sediment controls must be included as part of the project's design plan. The Dam Safety Program notifies project sponsors of the Commonwealth's Hazardous Material Control Program regulations, which address the storage, transport, and disposal of toxic pollutants, as well as the development of emergency preparation and response plans. The Office of Dam Safety also performs inspections of dam projects and conducts full engineering and hydrological inspections as warranted. In addition, the Office of Dam Safety requires specific details regarding the timing, extent, phases, materials, and designs of construction and repair/alterations. The management measure to protect surface water quality and habitat will be implemented through the Commonwealth's Basin Planning Approach. The Commonwealth's surface water permitting and planning responsibilities focus on management of watersheds. Nonpoint sources are being assessed and impacts from the operation of dams will be identified, with special focus on low flow problems and on violations of water quality standards. All structures, including dams, in tidelands and navigable rivers are licensed through the Chapter 91 Program. The Commonwealth has a comprehensive program to meet the management measure for eroding shorelines and streambanks. During the assessment phase of the Basin Planning Approach, the Commonwealth will conduct inventories of nonpoint sources for individual watersheds, including identification of sites with serious erosion problems. Based on this information, either proactive restoration work or enforcement procedures can be targeted to rectify these erosion problems. Projects on shorelines and streambanks are to be comprised of nonstructural engineering when possible. Regulations for Coastal Shorelines contain strict standards for siting, engineering design, and construction of proposed new work. In addition, the Wetlands Protection Program requires permits for activities in shoreline areas, and proposed projects must not alter the resource area or its functions. Local Conservation Commissions or the DEP may impose additional conditions on permits if necessary to ensure protection of critical areas and functions along shorelines and streambanks. Regulations for Inland Banks, and Regulations for Coastal Shorelines contain strict standards for siting, engineering, and construction of projects, and require that proposed new work shall not impair the physical stability of the bank, or alter water quality or habitat. VII. WETLANDS, RIPARIAN AREAS AND VEGETATED TREATMENT SYSTEMS FINDING: Massachusetts's program includes management measures in conformity with the 6217(g) guidance and includes enforceable policies and mechanisms to ensure implementation. RATIONALE: Massachusetts requires a permit for any activity involving dredge-and-fill, or other alterations, within a wetland area or within a 100-foot buffer zone around a wetland area. In addition, the Wetlands Protection Act provides the ability to address activities outside of wetland areas and their buffer zones. The Act contains language that expands jurisdiction to include any activity outside of the buffer zone that alters an area subject to protection under the Act. Regulations include explicit criteria for the protection of water quality and aquatic habitat functions of wetland and aquatic systems which are addressed in the review of permit applications. The Commonwealth's Stormwater Initiative will also help implement the management measure for protection of wetlands, by requiring the best practical method of treatment of new stormwater discharges to wetlands. Other practices to protect wetland functions such as acquisition efforts, local bylaws, and increased buffer zones, will be achieved through planning processes at the town level. The Commonwealth's Wetland Restoration and Banking Program coordinates efforts to implement restoration of wetlands on a statewide basis. Many federal and local organizations have become involved as partners with the Commonwealth in restoration projects. Examples of ongoing wetlands restoration projects are found in the Neponset River Watershed, Conte National Wildlife Refuge, Cape Cod, and Sagamore Marsh. The use of vegetated treatment systems will also be encouraged with the implementation of the new Statewide Stormwater Initiative. The Commonwealth is finalizing a manual of performance standards and guidelines for stormwater management in Massachusetts, which will provide comprehensive and effective guidance on the siting, design, operation, and maintenance of vegetated treatment systems. VIII. ADMINISTRATIVE COORDINATION FINDING: Massachusetts' program establishes mechanisms to improve coordination among Commonwealth agencies and between Commonwealth and local officials. RATIONALE: Massachusetts proposes to implement the coastal nonpoint program through a combination of several programs administered by agencies primarily described under Sections II.2.2 and 2.3 of the program submittal. The Commonwealth has negotiated Memoranda of Understanding between the relevant state agencies to ensure appropriate coordination among participating agencies. Copies of these are included under Appendix A of the Commonwealth's program. Several efforts are proposed to strengthen coordination among state agencies and between state and local officials. These include interagency agreements, an Interagency Outreach Coordinating Committee, and several interagency work groups comprised of members of the public and private sector who will also be responsible for measuring the effectiveness of program coordination and evaluation of the performance of the coastal nonpoint program. IX. PUBLIC PARTICIPATION FINDING: Massachusetts' program provides opportunities for public participation in the development and implementation of its coastal nonpoint program. RATIONALE: The Commonwealth describes many activities that provide opportunities for public participation in the development and implementation of its coastal nonpoint program. Opportunities for public participation include the continued use of special work groups for each Section 6217 source category, distribution of a community survey to all towns located within the Commonwealth's 6217 management area, publication of a series of articles on the 6217 program, several workshops held in various regions of the Commonwealth, and development of a long-term outreach strategy that will be updated annually. Comments solicited and received on the effectiveness of the Commonwealth's coastal nonpoint program will be used to evaluate and improve the public's opportunities to participate. X. TECHNICAL ASSISTANCE FINDING: Massachusetts has included programs that will provide technical assistance to local governments and the public for implementing additional management measures. RATIONALE: Massachusetts has proposed a variety of technical assistance efforts for local governments and the public. These efforts will emphasize several issues relative to nonpoint source pollution activities. Technical assistance will be conducted by a variety of sources including state agencies such as MCZM, Massachusetts DEP and Department of Food and Agriculture (DFA); and federal agencies, such as NRCS, in concert with DFA. The assistance will include traditional state agency technical assistance such as the preparation of guidance documents and other manuals, training workshops and seminars, one-on-one assistance by the state technical assistance staff, and financial assistance programs such as the Massachusetts Coastal Zone Management Program and EPA's Section 319 program. XI. ADDITIONAL MANAGEMENT MEASURES FINDING: Massachusetts' 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: The DEP's Basin Planning Program will be used to determine the effectiveness of (g) measure implementation. Using a five-year rotation schedule, the Commonwealth will evaluate all 28 of its basins to determine the results of (g) measure implementation and water quality monitoring efforts. 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 program guidance whereby the Commonwealth relies on site-specific evaluations to determine whether additional management measures are required. XII. CRITICAL COASTAL AREAS FINDING: Massachusetts' program includes a process for the continuing identification of critical coastal areas adjacent to impaired and threatened coastal waters. RATIONALE: The Commonwealth has developed threshold criteria based on a site specific evaluation process to identify critical coastal areas. The evaluation process incorporates the use of various sources of data to identify critical areas within each of the seven major coastal areas of the Commonwealth. The review process involves a two-level screening and evaluation approach. The first level of review involves the initial screening of the seven major coastal regions in order to determine their relation to the threshold criteria. In those areas where conditions or trends meet the threshold criteria, they will receive further evaluation during the second level. Generally, the Commonwealth's review process follows the second approach described in the program guidance whereby a State relies on site-specific evaluations to determine the extent of the critical coastal areas. XIII. MONITORING FINDING: Massachusetts' 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 two years, Massachusetts will develop a plan that enables the Commonwealth 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, Massachusetts identifies a number of monitoring activities that are currently being conducted, including traditional water quality monitoring under section 305(b) of the Clean Water Act and land use trends and analysis that provide information on geographic distribution of potential sources. There is also a discussion of the use of fate and transport modeling for specific geographic areas and loading assessment models that can be used to evaluate relative loadings of nonpoint source pollutants. However, Massachusetts does not describe how the these individual monitoring techniques will be coordinated and applied to assess over time whether the management measures are reducing pollutant loads and improving water quality. XIV. EVALUATION FOR BACK-UP AUTHORITIES For management measures where Massachusetts is proposing to use back-up authorities to ensure implementation, including the measures for agriculture, new development, and roads, highways and bridges, the Commonwealth will develop and apply credible survey tools to demonstrate the ability of the Commonwealth's approach to achieve implementation for these management measures. The use of credible assessment techniques is necessary in order for NOAA and EPA to evaluate, at the end of the 3 year period described in the March 16, 1995 guidance issued by NOAA and EPA entitled Flexibility for State Coastal Nonpoint Programs, whether the Commonwealth's approach has been successful or whether new, more specific authorities will be needed.
