Mr. Haastrup is certainly correct in emphasizing that the methodology underlying the use of FN curves deserves a more stringent examination. His discussion of uncertainty in FN data is very sobering. Even more sobering is his Figure 9 showing differences in FN curve estimates. How should a regulator apply a societal risk criterion to individual installations when uncertainties in estimated FN relationships are large? This question has not yet received the attention it deserves.
