Appendix D to Part 403 - Selected Industrial Subcategories
Considered Dilute for Purposes of the Combined Wastestream Formula
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
(paragraph 8(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.
