Ido. 1 <br />plant has been mostly removed and No. 2 pla.zt continues to <br />operate. About 1,800,000 tons of limestone raw materials are <br />required per year to supply plants 2 and 3• Sands:.c,ne is <br />supplied from a small quarry into the floor oC the limostonc <br />quarry at an annual rate o° 35,000 to 45,000 tons. Other rem <br />materials are purchased. <br />The limestone formation lies relatively flat with the Codell <br />sandstone quarry floor sloping about 25 feet per 1,000 i'ee~ to <br />the southwest. The surface is gently rolling with a dominant <br />southward drainage into the Arkansas river.
