Complaint: 12/13 Noxious odors for the last 4-5 days in the early morning hours. An odor was noted by a Valery employee near the refinery's Water Treatment Plant. The odor may have been the result of low odor threshold sulfur species in the wastewater. Odor may have been noticeable beyond the refinery fence line due to wind direction at the time. These events did not exceed permit limits or reportable quantities.
