The Holcim Portland plant consists of machinery and structures that are predominantly steel and <br />concrete. The plant site at present consists of two separate areas: Plant 2, which is the old plant, is <br />currently being demolished and Plant 3 where the new plant currently exists. There are portions of <br />the Plant 2 complex (cement silos, conveyor belts, and some buildings) that will remain and continue <br />to be used for production until the final cessation of operations at Portland. <br />Following are the estimates of steel, reinforced concrete, and lean concrete quantities for the two <br />areas: <br />Table E-3 <br />Holcim Portland Plant Structural Quantities <br />Plant 2 Quanti Cu.

The concrete will then be covered and the <br />area graded and contoured for drainage with a ]ow profile cover, then topsoiled and seeded. See <br />Figure F-1, Reclamation Plan Map, for the proposed cover slope/orientation. <br />Based on past Holcim experience, it is estimated that the cost of demolishing a plant of this size is <br />approximately $0.025/ton for all items removed (salvaged and land-filled). <br />Sims and Markers <br />The Holcim Portland plant and quarry are long-term facilities that are clearly marked at the <br />boundaries and with signs at all entrances. <br />Exhibit E - revised.doc <br />Page 5 of 5 <br />
