Ammonia: Temporary modifications of ammonia standards on five segments were reviewed.
Deleted: The ammonia temporary modification on White River Segment 21 was deleted because the Town of Rangely's permit had recently been reissued for discharges on the segment. Compliance schedules in recently issued permits are adequate to address any necessary treatment plant upgrade issues.
