It is that time of year when FESS/Ops performs the annual industrial cooling water, or ICW, flushing for main site (excluding the Village). The work is slated to be performed during from Oct. 30-Nov. 3, 8 a.m.-4:30 p.m. daily.

We will perform this work starting at Casey’s Pond pump house and continuing to the far reaches of the site, that is, to DZero and MI40, in a systematic fashion to flush approximately 20 miles of piping. Notification will be made to specific areas, in advance of our arrival, advising that we will be in the area and will need to have the area around fire hydrants cleared of vehicles.

We will provide and deploy safety cones, as needed, to assist in the restriction of vehicles, personnel and parking. All flushing-related equipment, as well as any dislodged debris from the ICW system, will be immediately removed following the completion of that areas flushing, and all mulch will be returned to its proper location.

During previous flushes, we have seen a momentary instances of pressure deviation of a couple of pounds but have not had any process equipment, to our knowledge, ever go down due to the performing of this work.

During the performance of this process there will be many areas that give the appearance of something leaking due to standing water. Please advise personnel in your area of this ongoing process and, if standing water is noted, please assist us by first identifying the water issue as an active leak or the remains of our previous and or ongoing flushing process. If you note water actively bubbling up out of the ground, please contact us immediately through work central at x3434, and ask for me or John Pollock.

Please keep in mind we have performed this flushing process for many years, with all the users running their experiments, and it has been transparent to the end user.

If you have any further questions or comments, feel free to contact John Pollock at x5253, 630-659-6211 (cell phone) or pollockj@fnal.gov, or call me at x3007, 630-951-5300 (cell) or shirley@fnal.gov.
