(b) The term wheat shall mean wheat delivered to a plant before processing.
(c) The term standard bushel shall mean a bushel of wheat weighing 60 pounds.
(d) The abbreviation MSBu shall mean 1,000 standard bushels.
Except as provided in §§ 125.30 through 125.32, any existing point source subject to this subpart shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT):
| Effluent characteristic
| Effluent limitations
|

| Maximum for any 1 day
| Average of daily values for 30 consecutive days shall not exceed—

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. In addition, the following pretreatment standard establishes the quantity or quality of pollutants or pollutant properties controlled by this section which may be discharged to a publicly owned treatment works by a point source subject to the provisions of this subpart.
