What everyone needs to know about diesel emission testing and manufacturer guarantees. First, regulations under 40 CFR 89.406 require that an engine be warmed up for 30 minutes before testing. This essentially exempts the startup emissions, i.e., "cold start", from regulation. "Cold Start" emissions are significant for NOx, CO, VOCs and PM. Exempting startup emissiions is prohibited under the Clean Air Act. Additionally, these same regulations require that malfunctions not be considered in the emission test results. Congress prohibits exempting startups, shutdowns and malfunctions (SSM) from emission calculations. EPA's rules governing diesel engine certification is therefore flawed and in violation of the CAA.

Environmental Justice Award 2013 -- Patty Martin
Patty Martin receives Environmental Justice Award
Power, Pollution and the Internet is an investigative series written by James Glanz of the New York Times. His coverage of data centers is a must read for anyone who thinks that cloud computing is environmentally friendly or sustainable. His tour of Quincy and the growing number of data centers is detailed in Data Barns in a Farm Town, Gobbling Power and Flexing Muscle.
Microsoft began construction of their facility in Quincy in 2006 without first applying for an air quality permit. Microsoft's 2007 permit claims they will generate power for the Grant County PUD, but Microsoft was never wired to generate power back to the PUD, nor was the PUD ever approached for this purpose.
Yahoo! also made the same claims in their 2007 permit. Both of these facilities "gave back" the excess fuel allocations and unused operational hours during their 2010-2011 permitting process in lieu of having to purchase and install pollution control devices such as diesel oxidation catalysts (DOCs), diesel particulate filters (DPFs), or selective catalytic reduction (SCRs) devices. This concession -- albeit from never used operational hours and fuel -- was determined to be of a greater benefit to "the state" than the use of add-on controls to protect our community.
