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:\nEffluent characteristic Effluent limitations\nMaximum for any 1 day Average of daily values for 30 consecutive days shall not exceed—\nMetric units (kilograms per 1,000 kg of corn)\nBOD5 0.81 0.27\nTSS 2.16 .54\nEnglish units (pounds per 1,000 stdbu of corn)\nBOD5 45 15\nTSS 120 30","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER N—EFFLUENT GUIDELINES AND STANDARDS","PART 406—GRAIN MILLS POINT SOURCE CATEGORY","Subpart A—Corn Wet Milling Subcategory"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-40.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:04Z","sha256":"7b07d9963b8c2a71c107794e4e60d97fd016eb3aa0b8ea4d52006aa778e245f4","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-406.11","next":"us/40-cfr-406.13"},"notice":"GroundRules: Original legal text.
