The 2015 prevailing wage rates are still in effect until the Department publishes the 2016 rates.  The Department is in the process of determining 2016 rates. July 15 remains the statutory deadline for local governments to provide copies of their rates to the Department, but it is not the deadline for the Department to publish its new rates.
