NPDES Phase II
1999
Description:
NPDES MS4 Storm Water Permit
US EPA promulgated NPDES Phase II in December 1999. By March 2003, regulated
smaller communities with service populations under 100,000 will be required to obtain
NPDES permit coverage. Their permits will require such items as: development and
enforcement of a program which will detect and eliminate illicit discharges;
development of MS4 maps and the establishment of ordinances and of enforcement
procedures; produce public education materials that describe the impacts of storm
water and actions to reduce pollution and must comply with state public notice
requirements regarding the adoption of plans, policies, and ordinances. In addition,
their permits will require the development of a program to address sediment and
erosion control for all construction sites equal to or greater than 1 acre. The program
must include an ordinance or other regulatory mechanism to require sediment and
erosion controls and include the following components: pre-construction review of
plans, procedures to receive/consider public comment, regular inspections during
construction. The program must meet minimum standards set by Ohio EPA’s general
NPDES construction permit.
General NPDES for Storm Water Associated with Construction Activity
By March 2003, small construction sites (between 1 and 5 acres) will be required to
obtain NPDES permit coverage for their storm water discharges associated with
construction activity. At that time, the exclusion provided to public entities with
service populations under 100,000 will also end.

Informal Programming
Ongoing
Description:
Several communities have informal programs that are complaint driven or by simple
observation (dry-weather discharges).
Annual Dry Weather Field Survey
Ongoing
Description:
Dry weather surveys are a part of the NPDES Storm Water permit requirements.
Under Phase I the City of Toledo’s MS4 permit required them to establish and/or
modify dry weather screening methodology to detect presence of illicit connections
within 6 months of receiving the permit. Toledo is also required to conduct annual dry
weather field screening of 20% (or 30 outfalls) of their major outfalls per year.
Sampling parameters include: odor, color, turbidity, floatables, estimated flow, pH,
phenols, chlorine, copper, and detergents.
When Phase II is implemented in March 2003, regulated small communities will be
