The <br />following should supply any additional information desired <br />for record purposes. <br />1. Exhibit B - Mining Plan <br />Attached is a cross-section sketch of this quarry <br />which shows the limited depth of the gypsum deposit. <br />We have no drill hole information at this location <br />and the thickness of the gypsum could decrease to the <br />west. The Mining Plan is for short successive north- <br />south cuts through the knoll with overburden from each <br />cut deposited eastward into the completed cut. <br />2. Exhibit E - Reclamation Plan <br />A. Seeding, fertilization and revegetation--The attached <br />letter from Mr. McCarty, District Soil Conservation <br />Service Conservationist states that the poor soil <br />doesn't seem to support vegetation. It may be that <br />some limestone fines would neutralize the gypsum con- <br />taminated soil to improve revegetation. No reclama- <br />tion would be practical prior to completion of the <br />removal of the entire gypsum deposit on this small <br />knoll. <br />P/[r. McCarty's recommended seeding mixture for the <br />nearby Slab Canyon Quarry should be satisfactory for <br />revegetation of this site. Fertilization will be used <br />as indicated by test prior to reseeding. <br />
