Wetlands: 4-14

The proposed onsite construction laydown area is roughly 9 acres and abuts the wetland buffers.  The laydown area will be used for construction parking and to store the materials needed to construct the facility which could include fabricated equipment components, equipment skids, pipes, wires and cables, conduits, raceway, etc.  There may be provisions for covered storage of more delicate components.  The area may also be used for staging fabrication and assembly of equipment and structures to improve construction efficiency.  Also, the area may be used for parking construction equipment and vehicles.  The engineering, procurement and construction (“EPC”) contractor will be required to have in place a Spill Prevention, Control, and Countermeasure (“SPCC”) plan which will require secondary containment around temporary fuel storage areas.

Invenergy will be required to obtain a Rhode Island Pollutant Discharge Elimination System (“RIPDES”) Construction General Permit from RIDEM prior to commencing with any construction activities.  The RIPDES Construction General Permit prohibits the discharge of pollutants into waters of the State and requires best management practices for soil, runoff, and erosion control as described in the Rhode Island Soil Erosion and Sediment Control Handbook. To be covered under this permit, a Stormwater Management Plan must be developed, incorporating the minimum standards of the Rhode Island Stormwater Design and Installation Standards Manual. A Soil Erosion, Runoff, and Sediment Control Plan will also be required.  The RIPDES Construction General Permit Application for the CREC and the required plans require the implementation of best management practices to fully protect the surrounding wetland areas at the site during construction activities.
