				  periods of time exceeding 96 hours and continuing at least through one
				  reproductive cycle; and will not result in a significant risk of adverse health
				  effects in a large human population based on available information such as
				  mammalian laboratory toxicity data, epidemiological studies of human
				  occupational exposures, or human exposure data, or any other relevant
				  data.
(h) New source means any
				  source discharging a toxic pollutant, the construction of which is commenced
				  after proposal of an effluent standard or prohibition applicable to such source

				  which is inherent to or unavoidably resulting from any manufacturing process,
				  including that which comes into direct contact with or results from the
				  production or use of any raw material, intermediate product, finished product,
				  by-product or waste product and is discharged into the navigable
				  waters.
(o) Air emissions means the
				  release or discharge of a toxic pollutant by an owner or operator into the
				  ambient air either (1) by means of a stack or (2) as a fugitive dust, mist or
				  vapor as a result inherent to the manufacturing or formulating
				  process.
(p) Fugitive dust, mist or
				  vapor means dust, mist or vapor containing a toxic pollutant regulated under
				  this Chapter which is emitted from any source other than through a
				  stack.
(q) Stack means any chimney,
				  flue, conduit, or duct arranged to conduct emissions to the ambient

(r) Ten year 24-hour rainfall
				  event means the maximum precipitation event with a probable recurrence interval

				  Paper No. 40, Rainfall Frequency Atlas of the United States, May 1961, and
