Pool closures Published Dec. 22, 2008 By Eli Whitman 75 Force Support Squadron HILL AIR FORCE BASE, Utah -- All base pools will be CLOSED until they are incompliance with The Virginia Graeme Baker (VGB) Pool and Spa Safety Act. This enactment was designed to ensure public safety in pools and spas through federal regulations that require the use of equipment that protects against body entrapment, hair entanglement and bodily injury. Currently there are no commercial retrofit kits presently available, therefore both indoor and outdoor pools will be closed for an indeterminate duration.
