Bucklin Point Facility Stormwater Management Plan

The Rhode Island Department of Environmental Management requires facilities with industrial activities that discharge stormwater to the surface waters of the State of RI to develop Stormwater Management Plans in accordance with the Multi Sector General Stormwater Permit. The NBC Bucklin Point Facility Stormwater Management Plan can be found here.

The North Pond is a wet vegetated treatment system (WVTS). The piped storm water flow to the North Pond is pretreated through sediment forebays. A 15 inch high weir plate has been installed on the outlet control structure of the pond to provide the 0.386 ac-ft of storage. Plants within the wet portion of the pond are tolerant of standing water.

The South Pond is maintained as a modified infiltration basin. The piped storm water flow into the South Pond passes over rip rap at the discharge for outlet protection and to trap sediments. Flow continues through a vegetated bed designed to tolerate both wet and dry conditions. The outlet gate from the South Pond to the Seekonk River is kept in a closed position. Storm water is not discharged from this pond under normal conditions. In the situation of an anticipated sustained wet weather event, if the depth of the stored water in the pond is three feet or higher (to the top of the first tier of gabion basket), the outlet gate will be opened and the pond drained at low tide to provide storage capacity for the predicted storm water volume and to prevent flooding on the site.
