Backup generators and on-site turbines add air pollution to neighbourhoods that often already fail air quality standards
#00209
Backup diesel generators and on-site gas turbines concentrate NOx and fine particulates in host neighbourhoods, many of which already fail ozone standards. At one Memphis site, 35 turbines were installed against a permit issued for 15.
#00222Require Tier 4 emission standards, metered runtime and permit-before-operate enforcement for on-site combustion
Set a Tier 4 baseline for new generators, meter and publish runtime hours, define emergency narrowly so scheduled outages do not qualify, and enforce permits before equipment operates. Virginia adopted a 0.60 g/hp-hr baseline from July 2026.
