I am concerned over the possibility of DEQ's proposal to allow more widespread use of the diesel generators used by Data Centers for backup. Allowing additional use, now during "planned outage events" could cause cause excessive pollution (air and noise) which puts the public in neighborhoods close to them at a greater health risk. It should not be allowed or should have strict regulations in place to protect residents in localities with these centers. I also fear that this could lead to the generators being used while transmission lines are being built and worked on, as well grids being upgraded. Would this allow the generators to also be used during periods of grid stress or the "demand response" programs. What is the cumulative effect of numerous generators and clusters using these generators on public health? Obviously, the more they are allowed to run (under DEQ regulations), the greater the pollution, and the risk to our air quality. DEQ must put the public health above all else and should not broaden their policy to include "planned outages", as it will most likely lead to more pollution and subsequent health hazards. If they do pass it, please adopt strict regulations, including not allowing Tier II generators to be run for planned outages near residential neighborhoods, schools, parks, etc. The public should also be notified prior to their useage, and each site should be inspected daily during use in order to monitor air quality, with the ability to shut down or limit use, if air quality is adversely impacted. I also do not understand why DEQ does not require battery and/or solar backups, as this is being proposed now for data centers (no pollution!!). Once again, PLEASE CONSIDER THE HEALTH OF THE PUBLIC FIRST AND FOREMOST, AS IS YOUR MISSION.
