NOTICE

Turner Construction, 830 4th Avenue South, Suite 400, Seattle, WA 98134 is seeking coverage under the Washington Department of Ecology's NPDES General Permit for Stormwater Discharges Associated with Construction Activities.

The proposed 75.4 acre project, known as MSN Data Center is located at Lot 7, Lot 8, Farm Unit 173 of Grant County Port District #1 in Quincy. Approximately 75.4 acres will be disturbed for construction of one (1) data center building and associated parking, and preparation for two (2) future data center buildings.

Construction activities will include clearing, grading, stockpiling, stormwater facilities, utilities, paving, constructing an industrial building, connecting to offsite sanitary sewer, and landscaping.

During construction the following erosion control techniques will be utilized to reduce soil erosion and sediment transport, these are to include silt fencing, interceptor trenches/swales, straw bale/stone check dams, culverts and dust control. Stormwater runoff will be routed to a sediment pond onsite and released at the same peak flow rate of the pre-developed conditions to the City of Quincy's storm drainage system located at the south end of the site. The storm runoff will be routed to an existing 18-inch pipe that crosses under the railroad tracks to the south. The 18-inch pipe outfalls into the City stormwater system and flows south along 7th Ave SW. South of N Street the City system drains into a series of irrigation ditches that parallels the West Canal.

Any persons desiring to present their views to the Department of Ecology concerning this application may notify Ecology in writing within 30 days from the last date of publication of this notice.
