Requirements
______________________________________________
2.0 Chapter Summary
• Outline the range of local offices involved in the review of various types of development
plans

• list the necessary items which must be included in any submitted development plan
• list the activities exempt from the Stormwater Management submittal requirement
• provide contact information for regional offices that review and comment on development
plan
2.1 Procedures
A complete set of plans for any given proposed development will include enough detail for both the
submitter and reviewing agency to determine which, if any, stormwater management regulations may
apply to the proposed development. Under current Federal law and current Ohio EPA stormwater
regulations, any construction activity (defined later in the chapter) requires compliance with the NPDES
program. Submittal of a completed Stormwater Pollution Prevention Plan (SWP3) (Chapter 4:
Construction Site Runoff Control) is a crucial requirement of the Phase I and Phase II implementation
stages of this program. However, other federal, state or local policies – including but not limited to those
for construction, wetlands, floodplains, endangered species or historical preservation – may regulate
disturbance less than one (1) acre. Submittal procedures vary by jurisdiction and compliance with the
standards in this Manual is generally confirmed at the site plan approval and building permit approval
stage. This could occur at the local or county zoning and building inspections departments, the local Soil
and Water Conservation District, the local planning commission office, or the local County/Municipal
Engineer’s office. Document submittals must demonstrate compliance with these standards either
directly on the plans or in backup reports, correspondence, or calculations. This Manual is designed
specifically for the northwest Ohio region and it is recommended that the developer, stormwater
engineer, or site designer verify submittal requirements with the local jurisdiction of the proposed
development site for village, township, city, and county procedures, and with State or Federal
regulations.
2.2 Definitions of Disturbance, Construction Activity, and Development
2.2.1 Disturbance:
For the purposes of this manual “disturbance” will be defined in accordance with the Ohio EPA’s
Construction General Permit, Ohio EPA Permit No.: OPHC000003. Part VII (G) of that permit defines
“disturbance” as “any clearing, grading, excavating, filling, or other alteration of land surface where
natural or man-made cover is destroyed in a manner that exposes the underlying soils.”
2.2.2 Construction Activity:
For the purposes of this manual “construction activity” will be defined in accordance with the Ohio EPA’s
Construction General Permit, Ohio EPA Permit No.: OPHC000003. Part I (B) (1) of that permit defines
