S. regulatory actions. For instance, in a proposed significant new use rule ( SNUR ) for perfluoroalkyl sulfonates ( PFOS ) published in the Federal Register on March 11, 2002 ( 67 FR 11014 ), the Environmental Protection Agency excluded from the SNUR the use of these substances in aviation hydraulic fluids in recognition of their critical importance to public safety, the absence of any known substitutes at this date and the long lead times required to develop and test substitutes for this sensitive ap-plication. The volume of PFOS chemicals used in aviation hydraulic fluids worldwide is small and results in little human exposure. It is expected that the mission-critical use of PFOS chemicals in avia-tion hydraulic fluids would be recognized as a permissible use under Annex B, if PFOS chemicals are considered for listing under the POPS Protocol in the future. In addition, this legislation acknowledges that the mechanism envisioned by the treaty to evaluate candidate chemicals for inclu-sion on the list of banned chemicals is a screening protocol that evaluates each substance for persistence, bioaccumulation and tox-icity. The screening mechanism is a valid way to identify those sub-stances in a hierarchy of potential risk. As such, the screening mechanism should be tempered with informed technical judgment so as to focus resources on those chemicals that present the highest realistic threat to human health. For example, though pigments, by their nature, would score high on the persistence scale, they do not score high when evaluated for bioaccumulation and toxicity. Pig-ments are well known to be nearly insoluble in both water and oil and thereby present little or no risk to human health.
