I am writing to ask that DEQ reject the proposed variance for the operation of emergency generators by data centers located in Loudoun during periods of alerts issued by the regional transmission organization, PJM. I do not believe the proposed variance is consistent with DEQ’s mission “to protect and improve the environment for the health, well-being and quality of life of all Virginians.” 

Our localities have approved far too many data centers without adequate plans for how these facilities will procure the electricity they require to operate continuously. Most of the on-site generators are powered by highly polluting diesel energy. Local communities would suffer the impacts of this poor planning, in the form of increased air pollution during the warmest months, when smog and other pollution issues are particularly acute.
