CHAPTER 7: Management Measures for
Wetlands, Riparian Areas, and
Vegetated Treatment Systems
A. What "Management Measures" Are
This chapter specifies management measures to protect and restore wetlands and riparian areas to protect coastal
waters from coastal nonpoint pollution. "Management measures" are defined in section 6217 of the Coastal Zone
Act Reauthorization Amendments of 1990 (CZARA) as economically achievable measures to control the addition
of pollutants to our coastal waters, which reflect the greatest degree of pollutant reduction achievable through the
application of the best available nonpoint pollution control practices, technologies, processes, siting criteria, operating
methods, or other alternatives.
These management measures will be incorporated by States into their coastal nonpoint programs, which under
CZARA are to provide for the implementation of management measures that are "in conformity" with this guidance.
Under CZARA, States are subject to a number of requirements as they develop and implement their Coastal Nonpoint
Pollution Control Programs in conformity with this guidance and will have some flexibility in doing so. The
application of these management measures by States to activities causing nonpoint pollution is described more fully
in Coastal Nonpoint Pollution Control Program: Program Development and Approval Guidance, published jointly
by the U.S. Environmental Protection Agency (EPA) and the National Oceanic and Atmospheric Administration
B. What "Management Practices" Are
In addition to specifying management measures, this chapter also lists and describes management practices for
illustrative purposes only. While State programs are required to specify management measures in conformity with
this guidance, State programs need not specify or require the implementation of the particular management practices
described in this document. However, as a practical matter, EPA anticipates that the management measures generally
will be implemented by applying one or more management practices appropriate to the source, location, and climate.
The practices listed in this document have been found by EPA to be representative of the types of practices that can
be applied successfully to achieve the management measures. EPA has also used some of these practices, or
appropriate combinations of these practices, as a basis for estimating the effectiveness, costs, and economic impacts
of achieving the management measures. (Economic impacts of the management measures are addressed in a separate
document entitled Economic Impacts of EPA Guidance Specifying Management Measures for Sources of Nonpoint
Pollution in Coastal Waters.)
EPA recognizes that there is often site-specific, regional, and national variability in the selection of appropriate
practices, as well as in the design constraints and pollution control effectiveness of practices. The list of practices
for each management measure is not all-inclusive and does not preclude States or local agencies from using other
technically and environmentally sound practices. In all cases, however, the practice or set of practices chosen by
a State needs to achieve the management measure.
