Reserve Silica Corporation (the Company) operates an all weather clean fill and inert waste dumpsite located at 28131 Ravensdale/Black Diamond Road, Ravensdale WA.  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 over 200 trucks per day 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.
