The provisions of this subpart are applicable to process wastewater discharges resulting from the following types of textile mills: wool scouring, topmaking, and general cleaning of raw wool.
In addition to the definitions set forth in 40 CFR part 401 and § 410.01 of this part, the following definitions apply to this subpart:
(a) The term wool shall mean the dry raw wool as it is received by the wool scouring mill.
(b) The term oil and grease shall mean total recoverable oil and grease as measured by the procedure listed in 40 CFR part 136.
(c) The term commission scouring shall mean the scouring of wool, 50 percent or more of which is owned by others, in mills that are 51 percent or more independent (i.e., only a minority ownership by company(ies) with greige or integrated operations); the mills must process 20 percent or more of their commissioned production through batch, noncontinuous processing operations.
(a) Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT):
| Pollutant or pollutant property
| BPT limitations
|

| Maximum for any 1 day
| Average of daily values for 30 consecutive days

(b) Additional allocations equal to the effluent limitations established in paragraph (a) of this section are allowed any existing point source subject to such effluent limitations that scours wool through “commission scouring” as defined in § 410.11.
(a) Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best available technology economically achievable (BAT):
| Pollutant or pollutant property
| BAT limitations
|

| Maximum for any 1 day
| Average of daily values for 30 consecutive days

(b) Additional allocations equal to the effluent limitations established in paragraph (a) of this section are allowed any existing point source subject to such effluent limitations that scours wool through “commission scouring” as defined in § 410.11.
Any existing source subject to this subpart that introduces process wastewater pollutants into a publicly owned treatment works must comply with 40 CFR part 403.
Any new source subject to this subpart must achieve the following new source performance standards (NSPS):
| Pollutant or pollutant property
