The EPA released final emission factors for the following ordnance categories: Fuses [Fuzes] and Primers; Mines and Smoke Pots; Grenades; Projectiles, Canisters and Charges; Large Cartridges (>75mm); and Small Arms. The air emission factors for ordnance are documented in Chapter 15 (Ordnance Detonation) of EPA's AP-42 (5th edition, Volume I). EPA's effort to develop and capture air emissions factors for ordnance has been a work in progress which started several years back when the Army first developed emission factors for nine ordnance items through testing conducted at Dugway Proving Grounds (a.k.a. bang box tests) and the Army Environmental Center. The ordnance for which emission factors were first developed included a 155mm illumination round, green and white star signal flares, and simulators (flash artillery, booby trap, and hand grenade).
