Best Management Practices Compendium
Best Management Practices (BMPs) have
been defined as practices or combinations of practices, industrial
techniques and good housekeeping principles determined to be the
most effective and practical known means of preventing or reducing
the amount of non-point source pollution. The overall philosophy
is to conduct everyday activities in an ecologically sound manner
in order to keep pollutants out of the water, since this is generally
cheaper and more practical than getting them back out later. They
are meant to protect and maintain the environment including soil,
air and water resources and the associated dependent organisms.
There are two general types of BMPs:
control or structural BMPs which involve after the fact removal
of contaminants; and
control or nonstructural BMPs which are designed to prevent
contaminants from getting into the water in the first place.
be feasible and economically-competitive practices and should
be tested under real world conditions. They are subject to change
as new and better practices are discovered and evaluated. Minor
differences in local conditions may result in different BMPs in
order to achieve the same degree of protection from one site to
the next. This means that today's BMP may be an ephemeral guide
and constant research is needed to replace old BMPs with new ones.
This state of constant change is not compatible with fixed legislated
practices; a much more reactive process is needed. BMPs should
indicate a desired goal and some currently known ways to approach
this goal, leaving the opportunity for immediate implementation
of newer and better ways as they become available.
As a service
to municipalities, regional offices, contractors and other agencies
who are trying to control non-point source pollution, we have
begun to collect in one document many accepted best management
practices from around the world. Since this is a large and active
field of study and new materials are becoming available daily,
we have chosen to put the information on a web page so that it
can be readily and economically updated and amended as new information
becomes available. This will be a living, changing, document.
