The EPA is proposing to relieve New York City of its obligation to complete the final design of a drinking water filtration system for the Catskill/Delaware watershed in upstate New York.
A filtration avoidance determination (FAD) issued by the EPA in 1997 allows New York City to not filter the drinking water from this system, but does require it to complete a final design for a filtration system that could be used if filtration were deemed necessary in the future.
