Please identify in detail the company’s plans regarding water quality, water use, storm water run off, and waste water.

RESPONSE:

 

The Project’s impact to water quality is detailed in Section 6.2 of the EFSB application.  We also are employing the use of ACC’s to minimize water consumption for the project. Table 6.2-3 summarizes the Project’s projected water use and wastewater discharge during a typical summer day firing natural gas, during an annual average day firing natural gas, and during a winter day with one combustion turbine firing natural gas and one combustion turbine firing ultra-low sulfur diesel (“ULSD”) fuel.  The Facility will only fire ULSD when the regional natural gas supply is curtailed during very limited periods in the winter months.  Invenergy has met with RIDEM to discuss the Project’s water use and wastewater discharge, and is working with RIDEM to identify measures to reduce Facility water use, particularly during the summer months when stream depletion can be a concern. 

 

The Project’s preliminary Stormwater Management Plan (“SMP”) is detailed in Section 6.4 of the EFSB application.  The Project SMP will meet the requirements of the RI Stormwater Design and Installation Standards Manual.  Invenergy is working with RIDEM to ensure that the final SMP developed for the Project meets all applicable standards and is fully protective of the water quality of nearby surface waters.

 

Invenergy will apply for a Wetlands Alteration Permit, a Water Quality Certification, a RIPDES Construction General Permit, and a Multi-Sector General Permit from RIDEM and an Individual Permit from the ACOE to ensure that Project impacts to wetlands, surface water, and groundwater during both construction and operation will be minimized.  Invenergy will also apply for a Wastewater Pre-Treatment Permit and an Order of Approval from RIDEM, and an Industrial Wastewater Permit from the Town of Burrillville to ensure that the wastewater discharge from the Facility meets all applicable water quality standards.

 

As detailed in Section 6.2 of the EFSB Application,  and through the completion of the required permitting processes with RIDEM, the ACOE, and the Town of Burrillville, the quality of wetlands, surface waters, and groundwater in the area surrounding the Facility will be protected and maintained, both during Project construction and operation. As detailed in Section 6.2 of the EFSB application, with the installation of the treatment system on PUD Well 3A, the operation of the Facility will actually improve the quality of groundwater in the areas affected by the contamination event, which occurred previously.
