4 The Engineer will consider, at the request of the Contractor, extensions to the delivery deadline for allowances for days, which prevents satisfactory and timely performance of the work because of weather, conditions caused by weather, or such conditions beyond the control of the Contractor.

Source of Materials: The County provided quarry site is an extension of Columbia County s Road Department s quarry that lays on the section line between the SE ¼ of 19 and the SW ¼ of 20, T. 10N., R.39E., W.M. being just outside the northeasterly city limits of Dayton, Washington. Mining and Operations (M&O) Plan: The pertinent sections of (2) Rock Cuts and 3-01 Production from Quarry and Pit Sites apply to this project and shall be supplemented as follows: Attached to these specifications is a site plan for the extension of Columbia County s designated quarry. This site plan shows the existing topography and the final configuration of the quarry once fully mined along with buffer zones, access points, quarry boundary roads, aggregate stockpile sites and the overburden stockpile area. The Contractor shall provide the engineer with an M&O Plan for the Engineer s review and approval. Approval of such plan does not relieve the Contractor of clearing, drilling and blasting enough material and or for crushable size to provide for the bid item quantities or quality. Excess material remains the property of Columbia County. The M&O Plan shall adequately show the area to be stripped for removal of overburden and the process and direction to the site plan s overburden stockpile area.

The M&O Plan shall show the configuration of the site upon completion of operations for this contract that allows access to all benches and shelves for future mining. The southerly perimeter road along the bottom of the hill shall be cleared and reopened by the contractor prior to completion of this contract. Measurement and Payment for the M&O Plan and all the work described in this section shall be incidental to the bid items. Columbia County 2018 Crushing Contract Page 3 of 7
