Non-Petrdeum Wastes: <br />The non•petrdeum waste products such as scrap lumber, scrap concrete, unsalvageable scrap <br />Iron, end office trash ere hauled to the phs. Salvageable scrap iron, inducting dd mining equip- <br />ment, is sdd to Iocai scrap dealers. <br />In-shu coal left In the phs Is usually in the form of un-mined seams at ph ends. The phs are all <br />backtllied as pert d the reclamatbn program. Any un-mined coal Is therefore covered with 20 to <br />150 feet or more d material. Any coal loll along the ribs would also be covered whh et least 20 <br />feet of material. <br />4.3.2.3 Contrd d Impacts <br />The nature d the wastes generated et the mine she end disposed of In the phs naturally minimizes <br />many environmental Impacts. Windblown debris Is nd a problem because most o1 the wastes are <br />lumber and tires. Any office trash disposed of In the pits wtli be covered sufficiently to prevent the <br />wind hom scattedng h. Nehher wood, rubber, nor paper wAl produce signHlcant quantities of <br />methane gas In this shuation. They are resistant to decay and will be burled deep enough that <br />methane production wfli be minimal. The materials ere Insduble In water end therefore present no <br />.~ leachale or runoff problems. The wastes would generally not provide a food source for animals <br />• and are buried deep enough that Insects and rodents will not be attracted to the area. <br />The relatively small amounts d waste disposed d In the pits over a large area precludes causing <br />subsidence problems. Although the wastes are all Ilammable, there will be no hot ashes or other <br />hot waste disposed of, so there <br />REVISED ~~~' 0 S ~9 <br />a ~ nom"'-REVISION <br />APPRQVED <br />DATE. 5-Z y0 <br />R-~f9 .~ <br />
