Prevention of Significant Deterioration (PSD) and a Notice of Construction.

The Washington Department of Ecology (Ecology) has received a request for changes to two air permits in regards to the Hanford Tank Waste Treatment and Immobilization Plant (WTP). The two permits are the Prevention of Significant Deterioration (PSD) and a Notice of Construction (NOC).

The proposed permits will allow the US Department of Energy (USDOE) to replace two approved diesel generators with two turbines, and will allow for increasing how long two diesel fire water pumps can run, from 110 to 230 hours per year.  The fire pump time increase will allow USDOE to maintain and properly test the fire water system.
