(Description of Minimization of Water
Quality Impacts)
The project consists of the bridge replacement of Bridge *500068 over Juniper Swamp in Johnston County. The proposed stormwater runoff from the proposed bridge has been
conveyed to a storm drainage system that outlets at toe of roadway fill. It should also be noted that there are no deck drains and thus no direct discharge into the creek.
