40 CFR 409.13 - Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable.
(a) The following limitations establish the quantity or quality of pollutants or pollutant properties which may be discharged by a point source where the sugar beet processing capacity of the point source does not exceed 1090 kkg (2300 tons) per day of beets sliced or where the soil filtration rate, whether natural or by deliberate design, within the boundaries of all waste water treatment or retention facilities associated with the point source is less than or equal to 0.159 cm ( 1/16 in.) per day; provided however, that a discharge by a point source may be made in accordance with the limitations set forth in either paragraph (a)(1) exclusively, or paragraph (a)(2) of this section exclusively.
|Effluent characteristic||Effluent limitations|
|Temperature||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 (90 °F).|
(2) The following limitations establish the maximum permissible discharge of process waste water pollutants when the process waste water discharge results, in whole or in part, from barometric condensing operations and any other beet sugar processing operation.
