Section IX-7123 - Appendix L-Selected Industrial Subcategories Considered Dilute for Purposes of the Combined Wastestream Formula

A. The following industrial subcategories 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 (the 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) of the decree);

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) of the decree);

3. the pollutants of concern are present in amounts too small to be effectively reduced by technologies known to the administrator or the state administrative authority (Paragraph 8(a)(iii) of the decree); or

4. the wastestream contains only pollutants which are compatible with the POTW (Paragraph 8(b)(i) of the decree). In some instances, different rationale were given for exclusion under Paragraph 8 of the decree. However, EPA has reviewed these subcategories and has determined that exclusion could have occurred due to one of the four reasons listed in this Appendix.

B. This list includes all subcategories that have been excluded for the above-listed reasons as of October 9, 1986. It will be updated periodically for the convenience of the reader.
