12 GeV Upgrade
Work continues on the few remaining areas of civil construction for the 12 GeV CEBAF Upgrade project. On the accelerator tunnel air conditioning contract, Warwick Plumbing & Heating continues exterior work in preparation for the chillers to be delivered in May and the summer accelerator shutdown to commence. The concrete slabs for the chillers are complete. Electrical work to power the chillers is near complete. The contractor started the exterior chilled water piping that will run from the chillers to the tunnel enclosure.

Environment, Safety, Health and Quality
MS4 at JLab
The MS4 system is the means to control and direct the stormwater runoff generated from whatever does not soak into or infiltrate the ground and instead flows overland through natural and man-made conveyance systems (i.e., ditches, drains, ponds). These systems serve a vital function by helping to keep our drinking water and other water bodies clean. These systems help regulate the surges of water from major storms and help control soil and chemical run-offs into the rivers and bays.
Major factors that work in concert to help protect the Hampton Roads environment include: types of land use, amount and frequency of precipitation, natural versus constructed drainage systems and stormwater control measures. JLab is doing its part and you can help too by reporting anything that doesn't belong in our ditches. Call ext. 7308 for more information or to report concerns.
