MOSES LAKE -- The Washington State Department of Ecology is accepting comments on a proposed permit to add 14 new backup generators to the two already at the Titan Data Center in Moses Lake.
The generators are powered by diesel engines and would be used during power failures to support the centers' data servers.
A state assessment showed that diesel engine exhaust particles and nitrogen dioxide in the exhaust may be at levels that require further scrutiny, but they still would meet state and federal health standards. At high enough concentrations, diesel engine exhaust particles can cause breathing problems. Long-term exposure can cause cancer.
Public comment will be accepted until June 3. For more information, go to ecy.wa.gov/programs/air/Tier2/Tier2_final.html.
