No, 22L actually. When ORD is in a west flow, Southbound and eastbound departures are typically conducted off of 22L. The O'HARE TWO DEPARTURE
http://155.178.201.160/d-tpp/1710/00166OHARE.PDF has a climb gradient requiring aircraft to be at or above 3000 feet by 5 miles from the ORD VOR and above 4000 feet by eight miles from the ORD VOR. This is done to prevent conflicts with MDW traffic. If the prevailing winds are strong enough to require 31C arrivals at MDW, the southbound and eastbound departures out of ORD tend to backup. If MDW were to construct a theoretical 18-36, Runway 18 arrivals would necessitate a flight path slightly more northerly than the current 31C arrivals, thus impacting ORD's departure flow.
