FACTOR 4: Public Health Impact
Is there a public drinking water supply located within S0 miles downstream of the effluent discharge (this includes any body of
water to which the r celving water Is a tributary)? A public drinking water supply may Include Inf/tratlon 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 S)
Determine the human health toxldty potential from Appendix A. Use the same SIC code and subcategory reference as in Factor 1. (Be
sure to use the human health toxicity group column — check one below)
