The following report on the Aeration Facility Project is for your information. This report will be transmitted whenever changes occur to the operation of the aeration facility, and as a result of data monitoring of dissolved oxygen in the Stockton Deep Water Ship Channel.
With dissolved oxygen (DO) levels beginning to drop below 5.0 mg/l last weekend, the Aeration Facility was turned on Monday, June 16, 2008 at about 10:45 a.m to begin the first of several planned on/off pulse tests. The system was operated at full capacity with oxygenated water with a DO level in the upper 30 mg/l range. Water was discharged into the Stockton Deep Water Ship Channel for four full days ending Friday, June 20, 2008 at about 10:45 a.m. The system will be off for the weekend and will likely be turned back on Monday, June 23, 2008 at 9:00 a.m.
