impediment to efficient ESA process due impediment to efficient ESA process due to:to:
Lack of congruence in water quality Lack of congruence in water quality requirements between DEQ and NMFSrequirements between DEQ and NMFS
Changing thresholds for effects Changing thresholds for effects determinations in ESA Section 7 determinations in ESA Section 7 consultations consultations
