[Code of Federal Regulations] [Title 40, Volume 28] [Revised as of July 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR406.17] [Page 82] TITLE 40--PROTECTION OF ENVIRONMENT 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: ------------------------------------------------------------------------ Effluent limitations ----------------------------- Average of daily Effluent characteristic Maximum values for 30 for any 1 consecutive days day shall not exceed-- ------------------------------------------------------------------------ Metric units (kilograms per 1,000 kg of corn) ----------------------------- BOD5...................................... 1.08 0.36 TSS....................................... 1.62 .54 pH........................................ (\1\) (\1\) ----------------------------- English units (pounds per 1,000 stdbu of corn) ----------------------------- BOD5...................................... 60 20 TSS....................................... 90 30 pH........................................ (\1\) (\1\) ------------------------------------------------------------------------ \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: ------------------------------------------------------------------------ Effluent limitations ----------------------------- Average of daily Effluent characteristic Maximum values for 30 for any 1 consecutive days day shall not exceed-- ------------------------------------------------------------------------ Metric units (kilograms per 1,000 kg of corn) ----------------------------- BOD5...................................... 0.43 0.14 TSS....................................... 0.66 .22 ----------------------------- English units (pounds per 1,000 stdbu of corn) ----------------------------- BOD5...................................... 24 8 TSS....................................... 36 12 ------------------------------------------------------------------------ [42 FR 62372, Dec. 12, 1977.
