The State of Washington Department of Ecology (Ecology) has received application to construct a new air pollution source. Dell Marketing, LP has proposed to build the Dell Data Center located within the north half of Section 7, Township 20 North, Range 24 EWM and accessed by Road D NW, Quincy in Grant County. The Dell Data Center will contain three separate building once it is fully constructed, and will install and operate up to 28 diesel engines. Each of the 28 diesel engines will power 3.0 megawatt electrical generators for a total of 84 megawatts of emergency backup electrical power. The diesel engine exhaust particulate (DEEP) emissions from the diesel engines were reviewed under a Second Tier Health Impact Assessment to evaluate health risks posed by the project. After review of the completed Notice of Construction application and other information on file with the agency, Ecology has decided that this project proposal will conform to all requirements as specified in Chapter 173-400 WAC. After review of the Second Tier Health Impact Assessment, Ecology concluded that impacts to the community will meet the requirements that are protective of health as contained in Chapter 173-460 WAC. Copies of the Notice of Construction Preliminary Determination, the Second Tier Petition Approval, and supporting application documents are available for public review at Department of Ecology, Eastern Regional Office, 4601 N. Monroe, Spokane, WA 99205-1295, and at the City of Quincy, 104 B Street SW, Quincy, WA 98848.
