• Price sheet

Reserve Silica Corporation (the Company) operates an all weather clean fill dumpsite located at 28131 Ravensdale/Black Diamond Road, Ravensdale WA. (directions)

The site has two below grade dump locations – the upper pit and the lower pit.

The site can accept clean fill and all material dumped must be free of petroleum or heavy metal contaminates. The site also accepts concrete, ground asphalt, large rocks and topsoil with strippings. Special accommodations have been made to accept spoils from Tunnel Boring Machines (TBM).

The site is set up to efficiently accommodate truck traffic and is accessible by a paved county road. The onsite road system has a one-way traffic loop, and critical portions of the onsite road with the most grade are paved to speed traffic flow. A wheel wash system is located on the adjacent property. While the Company charges by the truckload, it also has a weigh scale available for customers to use.

During the 2008 summer construction season the dumping capacity of the site was greatly increased with the construction of a large dumping pad on the east side of the lower pit. This allows operations from the high wall on the east side. The site has 4 separate dumping locations.

The lower pit is self-contained on all sides with no day lighted areas from prior mining, and is therefore structurally strong and can accept loose material such as TBM spoils. The pit is also impervious as can be seen by the water in the pit. Water accumulated in the pit is discharged through a culvert into a settling area. For that reason, the pH levels of the dumped materials must be such that the material does not raise the water above a pH level of 8.5.

The hours of operation of the site are currently from 7am to until 7pm Monday through Friday and 9am to 6pm on Saturday with no operations on Sunday. The Company has a request with King County DDES to amend the hours of operation to support public works projects such as Sound Transit Project.

The Company believes it qualifies as a Small Business as defined by the SBA.
