Question # 41

41. Are auxiliary facilities associated with activities at a facility in a covered SIC code exempt from reporting under Section 313?
No. The SIC system assigned SIC codes to auxiliary facilities according to the primary activity of the establishment that they served. An auxiliary facility was one that supported another facility’s activities. An auxiliary facility could assume the SIC code of another covered facility if its primary function is to serve that other covered facility’s operations. However, the NAICS system does not recognize the concept of auxiliary facilities and assigns NAICS codes to all establishments based on their own activities. For the purpose of establishing consistency with the NAICS classification methodology, EPA changed its interpretation of the applicability of TRI reporting requirements to auxiliary facilities. As a result, some auxiliary establishments will no longer be subject to TRI reporting.
