Dear reviewers

Our community of 3,300 residents in 1,863 homes in Gainesville is bordered on the East by the planned Prince William Digital Gateway with 37 data centers and nearly 2,000 backup generators and on the South (across I-66) by another soon-to-be completed 30 data centers with 1,500 more generators. 3,500 in total about the equivalent in pollution impact of 300,000 idling trucks. These generators will be within a few hundred feet to about 1.2 miles from homes in Heritage Hunt. Our community residents have a median age of 76 and 40% of them are in their 80s and 90s. Their health serious vulnerabilities include many conditions that diesel exhaust exacerbates. This is objectively dangerous to older residents. These include chronic pulmonary and cardiovascular weaknesses, asthma and more. The danger of so many generators running for more extended periods would be harsh and harmful to our people and other residents in the area. There simply must be some DEQ and Department of Health assessment of places where easing up on diesel operations could have especially profound adverse effects. This is not an abstraction but a real-life problem that must be addressed in way that is sensitive to the very lives and wellbeing of residents.  We will actively oppose the rule changes.  We simply have too much to lose with close to 70 data centers and over 3,000 generators on our doorstep.
