The Chert Mine, under the direction of the Public Works Director and with manpower assistance from the Public Works Department, is responsible for mining chert from the county's 114.62-acre chert mine and crushing, stockpiling, and loading it. The chert is used as a road building material for county road projects and is sold to the general public. Since the revenues generated from the sale of chert do not cover all of the Chert Fund's expenses, the General Fund must transfer funds to the Chert Fund to pay for normal operating expenses.
