Is there a publk drinking water supply located within S0 miles downstream of the effluent discharge (this includes any body of
water to which the receiving water is a tributary)? A public drinking water supply may Include infiltration galleries, or other
methods of conveyance that ultimately get water from the above referenced supply.
YES (If yes, check toxicity potential number below)
NO (If no, go to Factor 5)
Determine the human health toxidty potential from Appendix A. Use the same SIC code and subcategory reference as In Factor 1. (Be

A. Is (or will) one or more of the effluent discharge limits based on water quality factors of the receiving stream (rather than
technology -based federal effluent guidelines, or technology -based state effluent guidelines), or has a wasteload allocation
been assigned to the discharge?
