the nearest building. Contractors are responsible for assuring that the public and workers are kept a safe distance ITom the burn site. 6.6 The burn will be extinguished at least 2 hours before removal of the ash mound. Wetting of the ash will be necessary to reduce dust while removing ash. 6.7 The burn pits must be made oflimestone or other highly compactable material and be capable of supporting the wheel weight of the loading equipment. There should be an impervious layer of clay or limestone on the bottom of the pit to attempt to seal the ash ITom the aquifer. This impervious layer should be at least one (1) foot thick and should be repaired or replaced if scraped by bulldozers, excavators or other equipment. 6.8 The ends of the pits must be sealed with dirt ash or other material to a height of four (4) feet. 6.9 A 12 inch dirt seal must be placed on the lip of the burn pit area to seal the blower nozzle. The nozzle should be 3 to 6 inches ITom the edge of the pit. 6.10 There should be one (1) foot high waming stops running the length of the pits to alert equipment operators when they are close to the pit. The warning stops should be constructed of fireproof material. 6.11 No hazardous or contained-ignitable material is to be dumped into the pit. 6.12 The air flow should hit the wall of the pit at about 2 feet below the edge of the pit and the debris should not break the path of the air flow, except during dumping. 6.13 The length of the pit should be no longer than the length of the blower system and the pit should be loaded uniformly along the length. 6.14 The contractor is responsible for ensuring that the public is protected ITom the burn operation. Signs, fences and other measures can be used depending on site conditions. 6.15 Emissions must meet State and Federal standards for burning operations. 6.16 The Contractor shall be responsible for dust control while handling ash materials. 7. PORTABLE AIR CURTAIN INCINERATORS. 7.1 Portable incinerators use the same principals as air curtain pit systems. The primary difference being portable incinerators utilize a pre-manufactured pit in lieu of an on-site constructed earth or limestone pit. The pits are engineered to precise dimensions to compliment the blower systems. The composition and operation of the air curtain pit incinerator(s) shall conform generally to the drawings in Figures 1 and 2 of this Scope of Work.
