(d)  In cases where effluent limits established by Paragraph (b) of this Rule are not adequate to control settleable solids, the staff shall establish effluent limits for settleable solids.  Such effluent limitations for settleable solids will be applicable only when the projected average solids concentration exceeds 5.0 ml/l and the limitations established shall lie within the range of 0.1 ml/l to 5.0 ml/l.  The establishment of such limitations for any discharge shall be approved by the Director of the Division of Environmental Management.

(e)  For industrial categories or parts of categories for which effluent limits and guidelines have not been published and adopted, effluent limitations for existing industrial waste discharges, or new industrial waste discharges shall be calculated by the staff using the projected limits of the Environmental Protection Agency, the Environmental Protection Agency development document and other available information in order to achieve the purposes of Article 21.  Such limits developed by the staff shall be subject to approval by the Director.
