County’s Storm Water Program
is the Clean Water Coalition?
The Clean Water Coalition (CWC) is made up of multiple
municipalities and agencies in Erie County. The goal of the CWC
is to protect our water resources and comply with Ohio EPA’s
Phase II Storm Water Program.

is the Storm Water Program?
also known as Storm Water, can either soak into the ground or runoff
the land. As it runs off the land it can pick up harmful pollutants
that effect our drinking water and environment. In urban and suburban areas, much of the land surface is covered
by buildings, pavement and compacted landscapes with impaired drainage.
These surfaces do not allow rain and snowmelt to soak into the ground
which greatly increases the volume and velocity of storm water runoff.
National Pollutant Discharge Elimination System (NPDES) Storm
Water Program regulates storm water discharges from three potential
sources: municipal separate storm sewer systems (MS4s), construction
activities, and industrial activities. Most storm water discharges
are considered point sources, and operators of these sources may be
required to receive an NPDES permit before they can discharge. This
permitting mechanism is designed to prevent storm water runoff from
washing harmful pollutants into local surface waters such as streams,
rivers, lakes or coastal waters. For more informationcheck out this After the Storm PDF.
is Phase II? The U.S. EPA's storm water program addressed
storm water runoff in two phases. Phase I addressed storm water runoff
from large and medium MS4s. Large municipalities with a separate storm
sewer system serving a population greater than 250,000 and medium
municipalities with a service population between 100,000 and 250,000
had to obtain NPDES permits.
Phase II regulations address storm water runoff of MS4s serving
populations less than 100,000, called small MS4s . More particularly, small MS4s located partially or fully
within Urbanized Areas (UAs), as determined by the U.S. Bureau of
the Census, and also on a case-by-case basis for those small MS4s
located outside of UAs that Ohio EPA designates into the program.
Automatically designated Small MS4s, those in UAs, were required to
apply for permit coverage and develop and submit a SWMP by March 10,
2003. For more information:Small
