Code of Maine Rules › 06 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 096 - DEPARTMENT OF ENVIRONMENTAL PROTECTION - GENERAL › Chapter 528 - PRETREATMENT PROGRAM › Appendix 096-528-D - Selected Industrial Subcategories Considered Dilute for Purposes of the Combined Wastestream Formula

Current through 2024-29, July 17, 2024
The following industrial subcategories are considered to have
				  dilute wastestreams for purposes of the combined wastestream 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
				  (paragraph8(a)(iii)); or (4) the wastestream 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.
This list is complete as of October 9, 1986. It will be
				  updated periodically for the convenience of the reader.
