How Stormwater Regulations Work in a Growing Metropolis
With more construction and development comes more stormwater runoff. Luckily, there are protocols and requirements in place to mitigate some of the effects. Under U.S. EPA's National Pollutant Discharge Elimination System (NPDES) and Ohio EPA's stormwater program, construction activities in the State of Ohio disturbing one or more acres of land are required to obtain a permit. Additionally, any construction activities located partially or totally in the Big Darby Creek Watershed and parts of the Olentangy River Watershed have additional permit requirements that must be met in order to protect these critical waterways.
The general construction permit authorizes construction activity to discharge stormwater into the watershed but applies certain requirements that must be met to prevent erosion and stormwater pollution. Each site must also have a Stormwater Pollution Prevention Plan, often abbreviated as SWPPP or SW3P. The purpose of a SW3P is to identify where stormwater pollution discharge can happen and how the site is going to reduce or prevent the discharge. These stormwater requirements are necessary to protect our watershed and local sewer infrastructure.
Franklin Soil and Water provides many local municipalities in Franklin County stormwater management services, from performing site inspections at construction sites to conducting NPDES required community outreach and SW3P reviews to installing stream inserts and other conservation projects. We are also available to provide technical assistance and guidance to local residents and landowners on stormwater issues such as poor drainage, erosion, and more. You can contact our office here.
