CalPortland got one step closer yesterday to expanding its mining footprint in DuPont.

The City of DuPont has released a Draft Environmental Impact Statement that examines a proposal to sequentially clear, mine and reclaim 142 of 201 acres CalPortland Company owns adjacent to and north of its existing sand and gravel mine.

“Mining the North Parcel is necessary so we can continue meeting local and regional demand for high-quality aggregates,” said Pete Stoltz, permitting and government affairs manager for CalPortland. “This is especially high-quality material that is not available elsewhere.”

The North Parcel is designated as a Mineral Resource area under DuPont’s Land Use Code and Comprehensive Plan and is recognized by the City as a mineral land of long-term commercial significance in accordance with the state Growth Management Act.  

“The studies done for this DEIS show that we can mine this area in an environmentally responsible manner,” Stoltz said.

The DEIS indicates that North Parcel mining would result in no significant unavoidable adverse impacts to the environment. Plus, 45 acres of bluffs and nearly a mile of Puget Sound shoreline would be preserved as open space, wildlife habitat and visual screening.

The DEIS describes that aggregates would be mined in the same way as is currently done and processing would occur at the existing plant.  About 80 percent of the materials would continue to be transported by barge from the existing dock and loading facility at Tatsolo Point.
