This chapter of the law establishes that the Ohio Environmental Protection Agency provides regulations for stacks for industrial facilities. “Stack” means any chimney, flue, conduit or duct arranged to conduct any emissions to the ambient air, excluding flares. “Stack height” means the distance from the ground-level elevation at the base of the stack to the crown of the stack. If a stack arises from a building or other structure, the ground-level elevation of that building or structure will be used as the base elevation of the stack. For stacks in existence on January 12, 1979, the stack height calculated by the following formula: Hg= 2.5 H, where Hg = good engineering practice stack height, measured from the ground-level elevation at the base of the stack; and H = height of nearby structure(s) measured from the ground-level elevation at the base of the stack. For all other stacks, the stack height calculated by the following formula: Hg= H + 1.5 L, where L = height or projected width, whichever is less, of nearby structure(s).
