Storm Water Program Phase II Industrial No Exposure Certification
Background: U.S. EPA in its December 8, 1999 rulemaking regarding
the National Pollutant Discharge Elimination System (NPDES) Storm Water
Program has expanded the no exposure exemption to all categories of industrial
activity, except construction. The exemption allows facilities that do not
have process related materials exposed to storm water to opt out of obtaining
a storm water NPDES permit. While expanding the applicability of the exemption,
U.S. EPA added a requirement that a written certification of no exposure be
submitted to the appropriate NPDES permitting authority at least once every
five years. Ohio EPA is the NPDES authority in Ohio.
OHIO EPA STRATEGY: Ohio EPA has adopted the federal "No Exposure
Certification" application form and is using the federal guidance document
to determine whether facilities are eligible for the no exposure exemption.
Facilities may apply for this exclusion. A “No Exposure Certification” guidance, application form and
instructions document is available at the U.S. EPA Office of
Wastewater Management web site. Applicants should complete the form according to the
instructions in the guidance and mail it to:
Ohio Environmental Protection Agency
Division of Surface Water
Attn: John Morrison
P.O. Box 1049
Columbus, OH 43216-1049
If you qualify for no exposure certification, you are exempt from permit
requirements until
your facility no longer qualifies for no exposure certification.
If your facility changes and can no longer claim no exposure to
storm water you must submit the appropriate permit application
for storm water discharge.
