Results of dispersion modeling show that my maximum impact area is within the facility boundaries. Do I have to show compliance with the ambient air limits (AALs) on the facility property?
Env-A 1400 is intended to address the exposure of the general public to toxic air contaminants and therefore technically applies only to off-site ambient air impacts. Worker exposures to toxic air contaminants on-site are generally covered by applicable OSHA regulations. Therefore, unless the general public has open access to the facility property, on-site impacts are not covered by Env-A 1400. Although not required, DES recommends that the ambient air limits (AALs) established in Env-A 1400 be considered when addressing on-site air impacts.
