PERSPECTIVES ON THE COASTAL NONPOINT PROGRAM

NOAA image of nonpoint source pollution.Sept. 29, 2003 — Coastal waters are very valuable resources. They provide us with food, recreational opportunities, commerce pathways and solace. Coastal waters are home to countless marine species in addition to the majority of the human population. However, 30 years after the passage of the Clean Water Act that set “fishable and swimmable” goals for all navigable waters, many of the coastal bays and estuaries in the United States are still seriously impacted by water pollution. “No Swimming” and “No Fishing” signs still dot many shorelines. Although we have long-standing programs to manage point source pollution — pollutants discharged directly from pipes, such as from a factory or sewage treatment plant — dealing effectively with other types of pollution (i.e., nonpoint source pollution) is only beginning to receive widespread public attention and government support. The recently released “National Coastal Condition Report” indicates that the overall condition of U.S. coastal waters is fair to poor and that 44 percent of estuarine areas are impaired for use by human or aquatic life (EPA, 2001). The NOAA "National Estuarine Eutrophication Assessment" also found similar results with 40 percent of estuaries surveyed in the United States exhibiting highly eutrophic conditions due to nutrient over-enrichment (Bricker et al., 1999). Many of the impairments are caused by everyday activities that occur on the land.

What is Nonpoint Source Pollution?
Today, nonpoint source pollution — polluted runoff entering waterways from diffuse land-based activities — is the leading cause of water quality degradation to coastal waters (Pew, 2003). Nonpoint source pollution includes runoff from agricultural and forestry land, storm water runoff from urban areas and discharges from on-site sewage disposal systems (such as septic tanks). As rain water or snow melt washes over the land, it picks up pollutants (e.g., sediments, nutrients, organic matter, bacteria, oils, metals and other toxic chemicals) and transports them to coastal creeks, rivers, bays and estuaries.

Nonpoint source pollution, or polluted runoff, enters coastal waters from a variety of land-based sources.

Impacts of Nonpoint Source Pollution
Polluted runoff can have both ecological and human health impacts. Increases in polluted runoff have been linked to a loss of aquatic species diversity and abundance, including many important commercial and recreational fish species. Nonpoint source pollution has also contributed to coral reef degradation, fish kills, seagrass bed declines and algal blooms (including toxic algae). In addition, many shellfish bed and swimming beach closures can be attributed to polluted runoff. In 2001, more than 13,000 beaches in the United States had one or more pollution advisories or closings (NRDC, 2002). The last comprehensive survey of shellfish waters in the United States revealed that 40 percent were unsuitable for harvesting (EPA, 2001). Urban runoff, discharges from septic tanks and runoff from animal
feedlots — all types of nonpoint source pollution — were among the top five reasons for the closures.

Based on the current scientific information, it is clear that controlling nonpoint source pollution to coastal waters is crucial to preserve and restore the quality of estuaries, beaches and oceans. Therefore, NOAA’s management responsibilities for the Coastal Nonpoint Pollution Control Program play a critical role in preventing and reducing polluted runoff to the coastal waters. Despite many successes, the Coastal Nonpoint Program has encountered challenges that require careful consideration of nonpoint source management today and in the future. Future directions of the program and NOAA’s emerging strategy to improve the understanding and control of coastal nonpoint source pollution are discussed below.

Background of the Coastal Nonpoint Program
Runoff contaminated with bacteria from pet wastes, septic tanks, and other sources causes shellfish bed and swimming beach closures.In the late 1980s, it was clear that enhanced state and national commitment was needed to protect coastal waters from further degradation from nonpoint source pollution. In addition, because land use practices such as urban development and farming can directly lead to polluted runoff, better coordination between state coastal zone managers and water quality experts was needed
to effectively reduce polluted runoff in the coastal zone. Coastal zone managers oversee land use within the coastal zone — balancing human needs with protecting the coastal environment. Water quality managers, as their title implies, deal more directly with the quality of water within the coastal waterways.

Therefore, to address nonpoint source problems within coastal waters more effectively and to ensure coastal states have the tools necessary to address polluted runoff, Congress established the Coastal Nonpoint Pollution Control Program under Section 6217 of the Coastal Zone Act Reauthorization Amendments of 1990. The Coastal Nonpoint Program, jointly administered by NOAA and the U.S. Environmental Protection Agency, is unique in that it establishes a set of economically achievable management measures for states to use in controlling polluted runoff. The measures or “best management practices” are designed to control runoff from six main sources: forestry, agriculture, urban areas, marinas, hydromodification (shoreline and stream channel modification) and wetlands and vegetated shorelines (riparian areas). These measures must be backed by state enforceable policies and mechanisms — state authorities that will ensure implementation of the program.

Of the 34 eligible states and territories, to date, 16 have developed fully approved programs. Several other states are poised to complete their few remaining program requirements this year.

The Coastal Nonpoint Program establishes shared responsibilities for managing coastal water quality problems between state coastal zone management and water quality agencies. As such, the program is not a completely new and separate federal program. Rather, it is designed to combine the strengths of existing programs, providing a comprehensive framework and management approach for coastal nonpoint source pollution.

The Coastal Nonpoint Program focuses on pollution prevention. In other words, the program is designed to minimize the creation of polluted runoff rather than attempting to clean up already contaminated water — a very difficult and expensive process. The program encourages pollution prevention efforts at the local level, especially improvements to land use planning and zoning practices to protect coastal water quality. Land use practices recommended in the Coastal Nonpoint Program management measures include preserving natural vegetation, avoiding development within sensitive habitats and erosion-prone areas and limiting impervious surfaces (such as pavement, decking and roof tops) to the maximum extent practicable.

Successes of the Program
The success of the Coastal Nonpoint Program is best described in the context of the purpose
of the Coastal Zone Act Reauthorization Amendments of 1990, “to enhance the effectiveness of the CZMA of 1972 by increasing our understanding of the coastal environment and expanding the ability of state coastal zone management programs to address coastal environmental problems." In this context, the accomplishments of the program are many and varied. The national successes of the CNP include:

  • Producing Leading Technical Guidance: The program has produced leading technical guidance that formed the first complete national encyclopedia of practices to control polluted runoff.
  • Forging Strong Partnerships at All Levels: The program has forged strong partnerships at all levels of government (federal, state and local). Developing and implementing state
    Coastal Nonpoint Programs must involve the full range of nonpoint source pollution
    stakeholders, including state departments of environment, natural resources, agriculture, forestry, marine resources, fisheries, planning, and health, as well as federal agencies and local governments.
  • Moving Beyond Voluntary Runoff Control Efforts: A significant feature of the program is that while it allows states to implement voluntary management measures, state programs must also contain enforceable policies and mechanisms — ensuring the measures will be implemented even if the voluntary measures fail.
  • Evaluating Existing State Nonpoint Programs: Through program development, states conducted a complete inventory of available programs and resources, including statewide legislation, local zoning ordinances and funding mechanisms to address polluted runoff in the coastal zone. This "self-evaluation" provided state staff with valuable information on the strengths and weaknesses of existing efforts and, in some cases, identified unknown or underutilized tools. Each coastal state now has a complete inventory of all available nonpoint source programs and activities within the state supported by applicable state and local authorities that can be used to ensure program implementation.
  • Increasing the Awareness of Nonpoint Source Pollution Problems: Public participation, interagency workgroups and special task forces have broadened awareness of nonpoint source pollution as a serious issue for coastal water quality.
  • Encouraging Creative Problem Solving: States are tackling coastal nonpoint source pollution in new and creative ways. For example, Rhode Island is using money from its Clean Water State Revolving Fund to provide zero percent interest loans to municipalities and low interest loans to private borrowers to upgrade and repair their onsite wastewater systems. The funds are also being used by municipalities to develop onsite wastewater management plans and to track septic tank inspections.
  • Serving as National Models: In developing their Coastal Nonpoint Programs, coastal states have also served as national models for inland states. For example, because NOAA and EPA have emphasized developing Clean Marina Programs as a way to meet many of the marina management measures, numerous coastal states have developed or are developing Clean Marina Programs — sparking a national interest in the Clean Marina Initiative.

The Coastal Nonpoint Program has encouraged many states to develop Clean Marina Programs.In addition to the many national successes, the program has either been the driving force behind or contributed significantly to the creation or revision of many state statutes, regulations, policies, guidance materials and voluntary programs. Many coastal states have revised or enacted new statutes or regulations addressing storm water management, sediment and erosion control, site development, nutrient management, coastal resource management, sewage disposal and water quality to incorporate the Coastal Nonpoint Management Measures. For example, Virginia amended its Sewage and Handling Regulations to establish an 18-inch vertical separation distance between septic tank drain fields and the water table. Previously, the state only had a two-inch separation distance — not adequate to protect water quality. Several governors, such as Puerto Rico’s, have also signed Executive Orders adopting the management measures as public policy. New state initiatives have been developed to address clean marinas and failing septic systems, provide technical assistance to local governments and develop better tracking and monitoring programs to evaluate progress. The number of state and local guidebooks, BMP manuals, management plans and other technical assistance materials that have been created or updated to include the Coastal Nonpoint Program management measures number in the hundreds. These include Clean Marina Manuals, Sediment and Erosion Control Manuals, Storm Water BMP Guidebooks, Construction Site Chemical Control Manuals, Agriculture and Forestry Practices Manuals, Septic System Operation and Maintenance Guidebooks, Site Design Manuals, model local ordinances, conservation and development plans, and watershed plans.

Future Directions
Despite many accomplishments, the Coastal Nonpoint Program has encountered several obstacles that have slowed program development and implementation. One of the most predominant problems has been the length of time it has taken for states to develop fully approved programs. In the 13 years since CZARA was passed, only 16 out of 34 states have received full approval. The slow progress has been attributed to several factors, including: (1) insufficient funding for program development and implementation; (2) lack of state interest or political support for the program; and (3) poor coordination among federal and state agencies.

The Coastal Nonpoint Program continues to evolve to address these challenges. Future program goals include a more targeted use of limited funding, better tracking and reporting of the benefits of the program, and a transition from program development to program implementation and value-added assistance. Recently, NOAA targeted Coastal Nonpoint Program funds toward three identified priority areas: septic systems, clean marinas and coalition building. These areas have a coastal focus and are not often addressed directly through other federally funded nonpoint source programs. By targeting a portion of Coastal Nonpoint Program funds to these priority areas, NOAA and its state and territory partners are filling gaps left by other programs. With input from states and territories, NOAA will regularly reassess funding priorities for the Coastal Nonpoint Program in order to ensure limited funds are always directed to the most needed areas.

By improving the tracking and evaluation of Coastal Nonpoint Program benefits through objective, quantifiable outcomes, NOAA and its partners should be able to demonstrate the accomplishments of the program and provide a basis for comparison with other related efforts. For example, the NOAA Office of Ocean and Coastal Resource Management, in cooperation with the Coastal States Organization (which represents state coastal zone management programs), is in the process of developing national “performance measures” for water quality as one way for the program benefits to be assessed at the state and national level. More specific grant reporting requirements are seen as another way of improving Coastal Nonpoint Program visibility.

Through its efforts to control nonpoint source pollution, NOAA continues to protect and preserve coastal waters.Beyond the specific goals of the Coastal Nonpoint Program, NOAA continues to evaluate and coordinate its agency-wide efforts directed toward coastal water quality. Emphasis is being placed on improving understanding of nonpoint source pollution threats and effects to protect resources from further degradation and effectively respond to problems caused by nonpoint source pollution (e.g., harmful algal blooms). NOAA plans to capitalize on its core strengths of scientific research and management facilitation by assuming greater leadership in the areas of coastal water quality research, monitoring, modeling, environmental literacy and linking science to coastal management decision making. Examples of more effective means of managing coastal nonpoint source pollution will continue to be pursued at NOAA sponsored estuarine sites, including the National Estuarine Research Reserves. NOAA also hopes to continue working with state and local partners on site-specific integrated assessments by providing the scientific framework, data integration and coordination needed to ensure the appropriate management actions are implemented in coastal watersheds. At the national scale, NOAA plans on developing a monitoring and assessment program for coastal nonpoint source pollution and producing a national assessment every five years. This data will provide a strong scientific-foundation as NOAA collaborates with state and federal partners on national policies for protecting and restoring estuarine water quality through wise management.
