This announcement serves as notification that the US Environmental Protection Agency (EPA) intends to modify Purchase Order number EP11H000527 to the Texas Transportation Institute. Prior to the original award, an announcement of intent to issue a sole source Order was originally posted to FedBizOpps under reference number RFQ-DC-11-00034. The current contemplated action is a logical follow on to the referenced order which provides for the obtainment of the results of environmental chamber testing of auxiliary power units (APUs) fitted or equipped with diesel particulate filters (DPFs) on representative Class 8, sleeper cab equipped, trucks with 2007 or newer engines. Emissions and other relevant environmental impacts data and analysis from the APUs testing will be used to inform the SmartWay Transport Partnership's Idle Reduction Technology (IRT) Verification Program and EPA's proposed heavy duty truck greenhouse gas regulations.

The discussed modification will 1) provide for additional validation and finalization of the Idle Reduction Technologies (IRT) Verification Protocol; and 2) allow for TTI to identify and obtain two to four APUs for necessary testing under the current Order and for future EPA-related testing.

THIS IS NOT A REQUEST FOR QUOTE (RFQ) AND NO SOLICITATION IS AVAILABLE. Responses to this announcement must be in writing. Any questions should be directed to Michael Gilham via electronic mail at the below address.
