South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-9 - Water Pollution Control Permits › Subchapter 61-9.403 - GENERAL PRETREATMENT REGULATIONS FOR EXISTING AND NEW SOURCES OF POLLUTION › Appendix 61-9.403.D - SELECTED INDUSTRIAL SUBCATEGORIES CONSIDERED DILUTE FOR PURPOSES OF THE COMBINED WASTESTREAM FORMULA

Current through Register Vol. 48, No. 6, June 28, 2024
The following industrial subcategories are considered to have
				  dilute waste streams for purposes of the combined waste stream formula. They
				  either were or could have been excluded from categorical pretreatment standards
				  pursuant to paragraph 8 of the Natural Resources Defense Council, Inc., et al.
				  v. Costle Consent Decree for one or more of the following four reasons:
1) The pollutants of concern are not
				detectable in the effluent from the industrial user (paragraph
				8(a)(iii);
2) the pollutants of
				concern are present only in trace amounts and are neither causing nor likely to
				cause toxic effects (paragraph 8(a)(iii);
3) the pollutants of concern are present in
				amounts too small to be effectively reduced by technologies known to the
				Administrator (paragraph 8(a)(iii); or
4) the waste stream contains only pollutants
				which are compatible with the POTW (paragraph 8(b)(i)). In some instances,
				different rationales were given for exclusion under paragraph 8. However, EPA
				has reviewed these subcategories and has determined that exclusion could have
				occurred due to one of the four reasons listed above.
