(a)
Flow.
For industrial
				facilities, Qe(30) is used as the regulatory effluent flow. For municipal
				facilities, the design flow Qe(D) is used as the regulatory effluent flow. The
				regulatory effluent flow used for permitting purposes will not exceed the
				approved design flow in the WQMP for municipal facilities or the approved
				critical effluent flow in the WQMP for industrial facilities. For modeling
				purposes, a projected effluent flow justified by engineering calculations may
				be utilized.
(b)
Temperature.
The seasonal temperatures specified in the OWQS will
				be used to model point source effluent temperature unless discharge-specific
				data is available. If at least one year of average daily effluent temperature
				values is available, the upper 90th percentile value
				calculated from the dataset for the season will be used.
(c)
Water quality constituents.
For steady-state models, water quality constituents will be modeled at average
				values. For dynamic models, values will be established on a case by case
				basis.

				for the season will be used.

				of measured values will be used to establish receiving water conditions. For
				seasonal analyses, values calculated from the dataset for the season shall be
				used. For simple models, assumed conditions estimated from similar streams in
