Franklin County Engineer capital improvement
projects are built in accordance with the National Pollutant Discharge
Elimination System (NPDES) and specifically the Ohio Environmental Protection
Agency's Authorization for Storm Water Discharge Associated with Construction
Activity as regulated by the NPDES. Additional federal, state, and local rules
pertaining to storm water pollution shall also apply.
Contractors are required to co-sign the Ohio
EPA permit and Notice of Intent (NOI) as stipulated by the NPDES. It is the
prime contractor's responsibility to notify subcontractors of the Ohio EPA
requirements, have them sign affidavits that that they understand those
requirements, and furnish copies to the county engineer's office before
their associated work begins.
A prime contractor shall submit a Storm
Water Pollution Prevention Plan (SWP3) to the county engineer's office for its
approval within 20 days after the award of the construction contract. The SWP3
shall be prepared by a professional experienced in the design and
implementation of standard erosion and sediment controls and storm water
management practices addressing all phases of construction. The SWP3 shall
incorporate at a minimum "Part III, Section G SWP3 Requirements of the Ohio
EPA, Authorization for Storm Water Discharge Associated with Construction
Activity under NPDES.

Storm Water Pollution Prevention Plan (SWP3) Checklist
The county engineer's office shall also require
a description of all Best Management Practices (BMPs) and installation practices
a contractor plans to implement. The prime contractor shall inform the
county engineer's office in writing of all amended activities to the SWP3
whenever there is a change in design, construction, operation, or maintenance
that has a significant effect on the potential for the discharge of
pollutants to Ohio's waters, or if the SWP3 proves to be ineffective in
achieving the general objectives of controlling pollutants in storm water.
It is the responsibility of the prime
contractor to evaluate all sediment and erosion control activities to ensure
that no turbid discharge is released. They shall also be fully responsible for
all compliance activities for all areas outside of the designed construction
site. These areas include locations where soils are stockpiled, excavated
for the purpose of fill, or disposed of as fill outside of the work limits. The
prime contractor shall file an NOI with the Ohio EPA regarding these off-project
areas and furnish copies to the county engineer's office.
The county engineer's office will closely
monitor the implementation of the SWP3 with emphasis on construction and
continued maintenance of BMPs. We will provide the prime contractor notice of
any deficiencies found during required inspections as prescribed by the general
permit. Our inspection of sediment and erosion controls on the site will occur
at least once every seven days and within 24 hours after any storm event greater
than one-half inch of rain per 24-hour period. If there is a deficiency,
the prime contractor shall make necessary repairs within 24 hours of
notification or be assessed liquidated damages and other penalties in accordance
with Ohio Department of Transportation (ODOT) policies.
It is our goal to meet all Ohio EPA, ODOT and
local water pollution prevention standards for construction sites. The prime
contractor shall submit to us a description of the BMPs that will be employed
prior to the start of work, and we reserve the right to deny implementation of
any BMP that is determined to be non-effective prior to or during construction
activities.
