§ 409.12 Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available.
The following limitations establish the quantity or quality of pollutants or pollutant properties, controlled by this section, which may be discharged by a point source subject to the provisions of this subpart after application of the best practicable control technology currently available; provided however, that a discharge by a point source may be made in accordance with the limitations set forth in either paragraph (a) of this section exclusively, or paragraph (b) of this section exclusively, below:
(a) The following limitations establish the maximum permissible discharge of process waste water pollutants when the process waste water discharge results from barometric condensing operations only.
Effluent characteristic Effluent limitations
Maximum for any 1 day Average of daily values for 30 consecutive days shall not exceed—
1 Within the range 6.0 to 9.0.
2 Temperature not to exceed the temperature of cooled water acceptable for return to the heat producing process and in no event greater than 32 °C.
3 Temperature not to exceed the temperature of cooled water acceptable for return to the heat producing process and in no event greater than 90 °F.
