In 2016, the Ohio Environmental Protection Agency (OEPA) notified us of the need to obtain National Pollution Elimination System (NPDES) general permit coverage for Municipal Separate Storm Sewer Systems (MS4) as an urbanized area. Said permit would regulate storm water discharges under the purview of the Clean Water Act.
This letter will outline items you are required to comply with concerning erosion and sediment control for small construction sites:
- Existing vegetation shall be retained on idle portions of the building lot for as long as construction operations allow. Clearing shall be done for active working areas only.
- Temporary seed (annual rye, oats, etc.) and/or mulch shall be applied to areas, such as stockpiles, that are bare and not actively worked. This shall apply to areas that will not be reworked for 14 days or more.
- Stockpiles excavated from basements shall be situated away from streets, swales and/or waterways and shall be seeded or mulched as per item 2 above.
- Silt fence and/or wattles shall be provided and maintained in workable condition to control and filter sheet flow runoff from the building lot. It shall not be constructed in channels or areas of concentrated flow. Other sediment controls such as inlet protection and sediment traps shall also be used and maintained as needed at the direction of the inspector to control sediment runoff.
- Construction vehicle access to a lot shall be limited to one temporary access drive consisting of gravel or crushed rock and shall be maintained in an acceptable condition.
- Mud tracked onto the street or sediment settled around curb inlet protection shall be inspected for and removed daily or as needed to prevent accumulation. Accumulated material shall be removed by mechanical means (i.e. shoveling, scraping, sweeping) and shall not be washed off pavement or into storm drains.
- A dumpster for construction debris shall be onsite prior to commencement of construction. All construction site debris shall be placed in the dumpster at the end of every work day. The inspector may require a cover to ensure the items placed in the dumpster remain.
- On site portable restroom facilities shall be required for each individual lot.
- The haul route utilized to the site shall be the safest and shortest route possible. All non-weight restricted roads shall be utilized prior to utilizing weight restricted roads.
- Hauling of excavated or fill material shall be required to comply with Ohio General Permit OHC000005.
As a Contractor for residential new construction, Whitehouse requires a letter from the Developer of the subdivision, stating that they are the Operator and responsible party for the Storm Water Pollution Prevention Plan (SWP3) for the subdivision prior to requesting zoning approvals. The letter shall state that you and your subcontractors are aware of the requirements of the SWP3 for the subdivision and individual lot. In order to obtain a zoning permit, a site plan shall be submitted showing the required Best Management Practices (BMPs) for the individual lot. Required items specifically addressed shall be:
- Location of excavation
- Location of spoil pile
- Location of dumpster
- Location of stone/gravel entrance/exit drive. (One per lot)
- Location of onsite concrete wash area with silt fence
- Location of any curb drains/storm water drainage structures on the lot
- Location of restroom/porta toilet
- Direction of surface flow storm water off the building site and the body of water in which it drains
Upon review of the site plan, the inspector may require additional control measures be established and maintained for the individual lot such as silt screen and/or wattles.
If the Developer is no longer the Operator for the SWP3, the Contractor will be required to file for Individual Lot Notice of Intent (NOI) coverage through OEPA for Stormwater. Proof of obtaining coverage or that coverage is presently in place will be required prior to construction activity. Operators seeking coverage under this permit must submit a complete and accurate Notice of Intent (NOI) application using Ohio EPA’s electronic application form which is available through the Ohio EPA eBusiness Center at www.ebiz.epa.ohio.gov. Submission through the Ohio EPA eBusiness Center will require establishing an Ohio EPA eBusiness account with a unique Personal Identification Number (PIN) for final submission of the NOI. NOI application forms can be obtained at epa.ohio.gov/portals/35/storm/ILOT_instructions.pdf
With this coverage, you as the contractor/lot owner will be required to draft an individual lot Stormwater Pollution Prevention Plan (SWP3) and have the plan available at the job site for review upon request. Guidance for the development of your individual lot SWP3 can be found at:
A copy of the Small Residential Lot Stormwater Pollution Prevention Plan Template can be found on the Village of Whitehouse website whitehouseoh.gov/departments/public-service/stormwater-pollution-prevention/
All BMP required items in the individual lot site plan shall be in place and operational prior to commencement of construction activities. Any items found to be out of compliance will require immediate correction. Refusal to comply with Village of Whitehouse erosion and sediment control requirements may result in fine(s) being imposed and/or “Stop Work” orders for the individual lot construction sites.
