      CHAPTER I-ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 406-GRAIN MILLS POINT SOURCE CATEGORY--Table of Contents
 
              Subpart A-Corn Wet Milling Subcategory
 
Sec. 406.17  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best conventional pollutant 
          control technology.

    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 conventional pollutant control 
technology.
    (a) Subject to the provisions in paragraph (b) of this section, 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 available technology economically 
achievable:

\1\ Within the range 6.0 to 9.0.

    (b) The limitations given in paragraph (a) of this section for BOD5 
and TSS are derived for a point source producing products standard to 
the corn wet milling industry. For those plants producing modified 
starches at a rate of at least 15 percent by dry-basis weight of total 
sweetener and starch products per month for 12 consecutive months, the 
following limitations should be used to derive an additive adjustment to 
the discharge allowed by paragraph (a) of this section:
