FOREWORD 

This document contains guidance specifying management measures for sources of nonpoint pollution in coastal
waters. Nonpoint pollution is the pollution of our nation's waters caused by rainfall or snowmelt moving over and
through the. ground. As the runoff moves, it picks up and carries away natural pollutants and pollutants resulting
from human activity, fmally depositing them into lakes, rivers, wetlands, coastal waters, and ground waters. In
addition, hydrologic modification is a form of nonpoint source pollution that often adversely affects the biological
and physical integrity of surface waters.
In the Coastal Zone Act Reauthorization Amendments of 1990 (CZARA), Congress recognized that nonpoint
pollution is a key factor in the continuing degradation of many coastal waters and established a new program to
address this pollution. Congress further recognized that the solution to nonpoint pollution lies in State and local
action. Thus, in enacting the CZARA, Congress called upon States to develop and implement State Coastal Nonpoint
Pollution Control Programs.

Congress assigned to the U.S. Environmental Protection Agency (EPA) the responsibility to develop this technical
guidance to guide the States' development of Coastal Nonpoint Pollution Control Programs, which must be in
conformity with the technical guidance. EPA developed this guidance by carefully surveying the technical literature,
working with Federal and State agencies, and engaging in extensive dialogue with the public to identify the best
economically achievable measures that are available to protect coas.tal waters from nonpoint pollution.
This "management measures" guidance addresses five source categories of nonpoint pollution: agriculture,
silviculture, urban, marinas, and hydromodification. A suite of management measures is provided for each source
category. In addition, we have included a chapter that provides management measures that provide other tools
available to address many source categories of nonpoint pollution; these tools include the protection, restoration, and
construction of wetlands, riparian areas, and vegetated treatment systems.
In addition to this "management measures" guidance, EPA and the National Oceanic and Atmospheric Administration
(NOAA) have jointly published final guidance for the approval of State programs that implement management
measures. That guidance explains more fully how the management measures guidance will be implemented in State
programs.

We at EPA strongly believe that, working together, the States, EPA, NOAA, other Federal agencies, and local
communities can achieve the goal of the Clean Water Act to make our waters fishable and swimmable. We hope
that the enclosed guidance will help us all achieve our common goal.
