224. Are auxiliary facilities associated with activities at a facility in a covered SIC code exempt from reporting under Section 313?
No. An auxiliary facility is one that directly supports another facility /enterprise’s activities and therefore takes the SIC code of the facility supported. Auxiliary facilities located on separate property must report if they also meet the employee and activity thresholds. Auxiliary establishments that are located on multi-establishment facilities should be included in facility threshold determinations and release and other waste management calculations. For example, a spill of a toxic chemical from the on-site warehouse would be included in the covered facility’s release quantities.
