New source performance standards.

(a) NSPS for bis(2-ethylhexyl) phthalate, di-n-butyl phthalate, and dimethyl phthalate are reserved. (b) Any new source subject to this subpart must achieve performance standards ( i.e. , mass of pollutant discharged), which are calculated by multiplying the average process water usage flow rate for the finishing water processes at a new source times the following pollutant concentrations: Subpart C [Finishing water] Concentration used to calculate NSPS Pollutant or pollutant property Maximum for any 1 day (mg/l) Maximum for monthly average (mg/l) TSS 130 37 pH ( 1 ) ( 1 ) 1 Within the range of 6.0 to 9.0 at all times. The permit authority will obtain the average process water usage flow rate for the new source finishing water processes from the permittee.
