NON-POINT SOURCE POLLUTION AND STORMWATER MANAGEMENT

NON-POINT SOURCE POLLUTION: STRATEGIES FOR MUNICIPALITIES. R. Steven Nakashima, MSPH, MPA, RS - Special Projects Coordinator; Non-point Education for Municipal Officials (NEMO) Project; 300 Webster Avenue, New Rochelle, NY 10801; Tel/FAX: (914)654-9329; E-mail: nakacaen@cloud9.net

Water quality in America has improved over what it was 25 years ago. During that time the focus largely was on point sources of pollution that could be readily identified, monitored and regulated. As a result, the contribution of other, more diffuse sources has gained recognition to the extent that the Number 1 water quality problem is now Non-point Source Pollution.

Runoff from storms picks up pollutants as it washes across the landscape. Individuals concerned with water resource protection in urbanizing areas must confront the adverse effects of this polluted runoff. Land use within a watershed is intrinsically linked with the quality of the receiving waters. To improve water quality one must address land use, which is largely controlled at the local level of government. The decisions taken by local boards and commissions, such as the Planning, Zoning, Inland Wetlands, Conservation, Health and Land Trust, are shaping the landscape of communities for the decades to come.

Impervious surface coverage is a quantifiable land-use indicator that correlates closely with the adverse impacts of polluted runoff. Once the role and distribution of impervious cover are understood, a wide range of strategies to reduce impervious surfaces and their impacts on water resources can be applied to community level planning, site design and land use management. These strategies complement many current trends in planning, zoning, and landscape design that go beyond traditional water pollution concerns to address the quality of life in a community.

The Nonpoint Education of Municipal Officials Project (NEMO) is a research-based education project of the University of Connecticut’s Cooperative Extension System. NEMO provides training for land-use decision makers about prudent land use techniques and natural resources-based planning.

COMMUNITY RESPONSES TO STORMWATER POLLUTION: CASE STUDY FINDINGS WITH EXAMPLES FROM THE NORTHEAST.

Urban stormwater runoff threatens the Nation’s waterways and public health, and cost American’s hundreds of millions of dollars each year. Concerns about urban runoff and interest in proposed new Federal stormwater regulations prompted the Natural Resources Defense Council (NRDC) to document existing, effective stormwater strategies. Our report aims to encourage municipal action and empower community to address this critical issue. Information on more than 150 programs across the nation was compiled and evaluated to highlight effective pollution prevention, administrative, and financing strategies for addressing stormwater runoff. The case studies show on a practical level that stormwater management can be environmentally effective, economically advantageous, and politically feasible. The case studies are organized into five broad categories of stormwater management measures that roughly parallel those required in federal regulations: addressing stormwater in new development and redevelopment, promoting public education and participation, controlling construction site runoff, detecting and eliminating improper or illegal connections and discharges, and implementing pollution prevention for municipal operations. The purpose of this presentation is to provide a cross section of the numerous strategies currently being used by municipalities, developers, and civic groups to address stormwater runoff. The presentation highlights one case study in each management category from the Northeast: the Staten Island Blue Belt project, the Nonpoint Education for Municipal Officials (NEMO) program, Delaware’s Certified Construction Reviewer program, the Clean Charles 2005 Initiative, and Vermont’s Smart Salting program. The presentation is part of an ongoing outreach effort. NRDC’s goal is to expand the stormwater management knowledge base by sharing these case studies with municipal officials and concerned citizens across the country. Individually, the case studies provide detailed examples of effective tool and approaches used to address stormwater runoff pollution. Collectively, the case studies offer an outline for further successful stormwater management efforts. Elements found to be critical to the effectiveness of the highlighted programs include: a pollution prevention emphasis with structural treatment measures when needed; a focus on preserving and using natural features and processes; efforts that inform and involve the public; a framework that creates and maintains accountability; a dedicated and equitable funding source to ensure long-term viability; strong leadership; and effective administration. Applying these themes will help communities in all settings form a Sound stormwater policy. The case studies also demonstrate that stormwater management does not have to be overwhelming for communities. Thus, they serve as excellent guidance for communities developing or improving their stormwater management programs.

CONCURRENT SESSION B:
DREDGING AND HARBOR MANAGEMENT

THE ROLE OF HARBOR MANAGEMENT COMMISSIONS AS ADVOCATES FOR DREDGING FEDERAL NAVIGATION PROJECTS IN CONNECTICUT. Geoffrey Steadman, CT Harbor Management Commissions; 345 North Main Street; Westport, CT 06880; Phone: (203) 226-9383; Fax: (203) 221-0819.

Federally-authorized navigation projects are maintained by the U.S. Army Corps of Engineers (Corps) in some 30 Connecticut waterways. Included are channels and anchorages authorized by Acts of Congress in the 1800s and early 1900s to serve waterborne commerce. Many changes in harbor uses and conditions have occurred since then; in some areas, waterborne commerce has declined and recreational boating is now most prominent.

The CT Harbor Management Act (HMA) of 1984 (CGS Sec. 22a-113k through Sec. 22a-113t) gives municipalities the authority to establish harbor management commissions (HMCs) and prepare harbor management plans. Those plans address a variety of issues, including dredging, navigation, and resource protection issues. The Norwalk, Fairfield, and Stratford HMCs are charged with serving as municipal advocates for maintenance dredging of the Norwalk Harbor, Southport Harbor, and the Housatonic River Federal navigation projects, respectively, and for working with the Corps and the CT Department of Environmental Protection (CT DEP) to achieve timely maintenance dredging. These charges are specified in each community's harbor management plan.

The role and experience of the HMCs pursuing Federal dredging is instructive with respect to harbor management and dredging processes and the complex issues now affecting dredging and dredged material disposal in Long Island Sound (LIS). Timely and economical dredging is necessary to maintain the viability of the State's marine-related businesses and industry and to provide public access to the Sound for the many thousands of people who enjoy recreational boating and other activities that depend on safe navigation. At the same time, dredging and dredged material disposal must be carried out in a manner that does not degrade the Sound's vital natural resources and ecological functions.

Information provided by the HMCs to the Corps to advance the Federal dredging process includes information to establish the need for dredging, including the identification of priority dredging areas and detailed information on water-dependent facilities and vessels. In addition, each HMC has documented the importance of its harbor to the community and the management of the harbor in accordance with the Corp's "open to all on equal terms" policy. Also provided is information on oil and chemical spills and points of discharge into the harbor needed to develop dredged material sampling and disposal plans.

In 1999, a Federal Environmental Impact Statement (EIS) process for designating a LIS disposal site (or sites) under the Federal Ocean Dumping Act is underway. The outcome of this process may have profound effect on the future dredging of Connecticut harbors.

The New York State Department of Transportation's (NYSDOT) Environmental Initiative is a paradigm shift involving the proactive commitment of DOTs organizational beliefs and strengths to make an affirmative contribution to the environment.

As with most DOTs, strict regulatory compliance had long been a part of the culture at NYSDOT. While this reactive approach did reduce unnecessary environmental damage, it was clearly never going to address some of the root causes of the traditionally contentious transportation/environment dynamic.

The breakthrough came with a look beyond mitigation. By proactively constructing environmental enhancements as an inexpensive, routine part of normal work, we at NYSDOT have brought our culture into alignment with our personal beliefs. This, in turn, has redefined our relationship with the environmental community. As these groups have become partners instead of policemen, approval times have improved, better projects are being built faster, mitigation costs are down, and staff from both sides have a new sense of teamwork and pride.

Bottom line: "It's OK to be green." DOTs can easily do more than just "fix what we break." An environmental ethic is not just the right thing for a public agency to do, it is a smarter way to do business.

WETLANDS RESTORATION AND CREATION TECHNOLOGY

TREATMENT WETLANDS FOR REMEDIATION. Thomas Ferraro (Presenting Author); Ecology and Environment, Inc.; Corporate Headquarters; 368 Pleasant View Drive; Lancaster, NY 14086; E-mail: tferraro@ene.com and Agnieszka Rawa; Ecology and Environment, Inc.; 1700 N. Moore Street; Rosslyn Center, Suite 1610; Arlington, VA 22209; E-mail: arawa@ene.com.

Wetlands have all of the basic elements needed for attenuation of chlorinated hydrocarbons, including high organic carbon in the sediment to bind contaminants; high microbial density and diversity in the sediment to biodegrade contaminants; and both aerobic and anaerobic conditions to ensure the contaminants are fully degraded without the accumulation of potentially toxic intermediates such as vinyl chloride. Treatment wetlands are constructed wetlands that are designed to enhance natural biogeochemical processes to degrade organic compounds. The presentation will focus on the use of treatment wetlands for remediation of groundwater and surface water contaminated with organic compounds. Specifically, Ecology and Environment, Inc. (E & E) will describe how natural physical, and biochemical processes in wetlands can be used to degrade organic contaminants as well as to reduce metal contaminants. E & E will illustrate the application of treatment wetlands to organic contamination by describing an ongoing pilot study at a site in Michigan. The goal of the study is to determine whether chlorinated organic compounds can be effectively degraded by treatment wetlands. Although wetlands have been used for remediation of metals, petroleum compounds, landfill leachate, and municipal and industrial wastewater, this is the first instance that a treatment wetland is being used for remediation of chlorinated hydrocarbons.

GEOSYNTHETIC CLAY LINER DESIGNS IN WETLAND APPLICATIONS. Joseph Carmo, Carmo Environmental Systems, Inc.; 1866 Maurice Avenue; East Meadow, NY 11554; Phone: (516) 794-7904; Fax: (516) 794-5122; E-mail: josephcarmo@compuserve.com.

Sodium bentonite has been used for decades as a soil-admix for compacted clay liners in wastewater treatment ponds and landfills. The recent development of the geosynthetic clay liner (GCL) has simplified installation and expanded applications. GCLs are pre-fabricated liners of sodium bentonite bonded between two geotextiles. This paper will review three projects where GCLs were used as a liner to create wetlands in difficult conditions (New Jersey DOT I-287 Project; Marathon Battery NPL Site; and Westchester County Airport).

When the I-287 extension in New Jersey was designed through Federally-designated wetlands, the NJ DOT identified a 32-acre parcel for wetlands mitigation. Above-normal precipitation after the beginning of construction caused the water table to rise into many of the excavated areas of the site. The contractor was unable to dewater such a large area to install a compacted clay liner. A needle-punched GCL was proposed and accepted as a substitute for the compacted clay liner. Despite difficult conditions, the GCL was successfully installed over an 18 month period.

Marathon Battery is a Superfund site in upstate NY where a manufacturing plant discharged cadmium waste into Foundry Cove and the Hudson River. The site was divided into three areas, one of the areas being a 5-acre marsh. Remedial action called for removal of contaminated soil and restoration of the marsh. Due to the low strength of underlying marsh soils, a compacted clay liner was deemed infeasible. Instead, an alternative design with a needle-punched GCL underlain with a geogrid was chosen. The contractor waited until the winter freeze before installing the liner. The GCLs ability to be installed in freezing weather was critical to the success of the project.

Westchester County Airport needed to divert a stream as part of an expansion. The project used a polyethylene-laminated GCL to line the new length of the waterway. The liner was covered with 2 feet of soil and planted to restore a natural setting.

BIOENGINEERING APPLICATIONS FOR WETLAND CREATION AND RESTORATION. Gary L. Gentile, Senior Landscape Architect; New York State Department of Transportation, Region 10; 250 Veteran Highway, Hauppauge, NY 11788; Phone: (516)952-6219; Fax: (516)952-6936; E-mail: ggentile@gw.dot.state.ny.us.

The New York State Department of Transportation on Long Island has had the opportunity to use bioengineering methods on numerous projects as mitigation, creation and restoration for both tidal and freshwater wetlands. As the water quality issues impact the sole source aquifer on Long Island, the Department has looked at better ways to treat highway runoff and erosion control issues. It has been effective with the Department issuing guidelines for applications and the regions developing details for site specific use.

Within Region 10 on Long Island we have developed specifications and pay items for the use of biologs, coconut fiber mats, GRES (Geotextile Reinforced Earth System) walls in tidal wetlands, biofiltration recharge and detention basins, ecological recharge basins, and the topic of this talk: bioengineering for tidal slope stabilization and restoration. On Fire Island, along the Ocean State Parkway, there are numerous areas where either the bay or the ocean wants to reconnect old inlet locations. It was the Departments responsibility to come up with a solution to preserve the eroding slope that were within twenty feet of the roadway, acceptable to NYSDEC, and somewhat maintenance free. The solutions ranged from the usual broken concrete, stone, geotextile mats, erosion blankets, jute mesh and whatever else was available on the market.

Having just finished a tidal wetland project with geotextiles, bio-logs, the Landscape staff felt that we had an opportunity to try both the new and the old ways at slope stabilization. The details were discussed with the engineers, landscape architects and environmental staff to analyze the costs, long-term benefits, materials past experience, and the ability to access the site. The solution was to do two sites one with the stone/geotextile treatment, and the second site a combination of geotextile slope mat, biologs, toe of slope protection, tidal wetland plants, intertidal plants and upland plants. Both project sites were started in the early spring and finished in the early summer with the slope plantings on the bio-engineered site . Both sites endured storm tides, strong winds, extremely high tides and other abuses that normally erode the shorelines at water’s edge.

Our Regional staff and Main Office staff will monitor the slope treatments success and/or weaknesses over the next couple years to see if this will become a standard treatment.

NATIVE PLANTS FOR LONG ISLAND WETLAND CREATION AND RESTORATION PROJECTS. Ellen Talmage; H.R. Talmage & Son/Talmage Farms Nursery; 2975 Sound Avenue; Riverhead, NY 11901-9879; Phone: (631) 727-0124; Fax: (631) 727-0326; E-mail: talmage@I-2000.com

What is a native plant? Horticulturists have very different points of view on this matter. However, everyone agrees that the plants best suited for tough growing situations are native or naturalized plants. Why experiment with conventional garden plants when they can waste a lot of time and money. Select from the native plants at our nursery because they are adapted to surviving in the challenging sites of your landscape.

Simplified Definitions:

President Clinton has signed a bill that will affect the nursery industry. On Feb 3, 1999, an Executive Order on Invasive Species was signed that directs federal agencies to expand and coordinate efforts to control the introduction and spread of invasive plants. The (EBISC) Executive Branch Invasive Species Council has been formed to oversee the implementation of this Executive Order. No federal monies will be used to fund projects that use invasive plants. This trend will most likely trickle down to state and county funding, so PLEASE start using alternatives to the plants listed below.

Problem plants that are particularly widespread on Long Island, NY

Although some of these plants may not present problems in every part of the state, each is a major problem somewhere and therefore a potential hazard. I am involved in the production of an exciting brochure created by the Ad Hoc Group for Invasive Plant Management in New York State. This brochure will offer suggestions for alternatives to invasives in NY State. Please call or send Talmage Farm your address, and we will be happy to send you a copy.

THE JAMAICA BAY DAMAGES ACCOUNT: MITIGATION FOR NATURAL RESOURCE DAMAGES IN NEW YORK CITY. Jodi McDonald; NYSDEC; 47-40 21st Street; Long Island City, NY 11101; Phone: (718) 482-4064; Fax: (718) 482-4502; E-mail: jmmcdona@gw.dec.state.ny.us

The New York State Department of Environmental Conservation (NYSDEC) is charged with protection of the state’s natural resources. Its objectives include the acquisition and preservation of natural areas and their management for conservation and suitable multiple uses throughout New York State.

The Jamaica Bay Damages Account (JBDA) is a fund administered by the NYSDEC for the purpose of "restoring, replacing, or acquiring the equivalent of any natural resources determined to have been injured, destroyed, or lost as a result of the release of hazardous substances" from five municipal landfills owned and operated by New York City. Three of the landfills, Edgemere, Pennsylvania Avenue, and Fountain Avenue are located along the shoreline of Jamaica Bay. One landfill, Brookville Avenue, is in Staten Island (at Richmond Creek), and one, Pelham Bay Landfill, is in the Bronx (Pelham Bay Park). Vast amounts of wetlands and other habitats were destroyed with the creation and use of the landfills. The creation and enhancement of existing habitats to offset the significant loss of natural resources is a major function of this program.

NYSDEC employs multiple funding strategies to best utilize JBDA monies. These techniques include using JBDA as a standalone source of funds, partnering with other governmental agencies, and leveraging JBDA dollars to solicit grant funding from Federal and State sources. JBDA fully funded the acquisition and restoration of the Norton Basin Natural Resource Area, which included tidal wetland, maritime grassland, and dune restoration. Where other departments have compatible restoration goals, partnering with Federal, State, and Local agencies can achieve multiple programmatic goals. JBDA has also committed $215,000 as match for $630,000 in grants from various funding sources to restore 3 acres of tidal wetlands. These strategies help to augment the size and number of projects that can be conducted and will increase the longevity of this program. There are many opportunities for tidal wetland restoration in New York City and NYSDEC, through the JBDA program, is contributing to the ongoing recovery of the natural resources of New York City.

MANHASSETT BAY WATER QUALITY IMPROVEMENT PLAN. Jennifer Wilson-Pines, Manhasset Bay Protection Committee; c/o Town of North Hempstead, PO Box 3000, Mahasset, NY 11030; Phone: (516) 767-3454.

The Manhasset Bay Protection Committee was formed with an inter-municipal agreement of cooperation between the eleven villages adjacent to the Bay, the Town of North Hempstead and Nassau County. The Committee’s initial goal was to produce a Water Quality Improvement Plan with recognition that non-point source pollution problems cross municipal boundaries. An inter-municipal organization can take a more global view of a region and is a more desirable umbrella for funding projects.

Through a public participation process the Committee identified water quality goals for the Plan to address. They are: swimming, fishing, wetlands and habitat restoration and marine economic and recreational uses. The Plan identified twelve capital projects within the watershed. They are the "point sources" affecting the water quality of the Bay. Most of these areas also contain fresh or tidal wetlands. The estimated total funding for all the projects is between 9 and 12 million dollars. The projects are prioritized into three tiers. The 1st level projects are:

Some of the projects are already in planning or construction phases.

In addition to the capital projects, the Plan identifies upland controls of non-point source pollutants (bacteria, nitrogen, sediment and litter/debris) through updated, coordinated and enforced ordinances, public education and participation and developing best management practices.
