the manual provides design information for four groups of sediment control structures and treatments which are suitable for use on small areas in surface coal mining. a detailed design procedure is given for each group which will estimate the total amount of settleable solids from a small area with a sediment control structure or treatment for a specific design storm. a procedure is also given for estimating the mean annual sediment yield from a small area information on design, installation, maintenance and cost is given for each sediment control measure. methods for determining the maximum allowable area for each sediment control measure and for design of combined sediment control systems are presented. the design procedures contain numerous nomographs, graphs, and worksheets to facilitate the use of the design procedure. the sediment control measures, design procedures, and materials in the manual are applicable to coal bearing regions of the continental unted states
