SUBJECT: Tar Sands Holding II Inactive Site at Asphalt Ridge
The Division of Air Quality (DAQ) initiated a 10-Year Review for Approval Order (AO)
DAQE-AM0117160002-08 dated August 26, 2008. Upon conversations with the office manager,
Annette Burrows, and review of recent inspection reports, the DAQ has determined that the Tar
Sands Holding II facility at Asphalt Ridge is an inactive site. The site has not been operational
since February 2010 (see Memorandum DAQC-555-11) and has been through many sale
processes. According to a pre-NOI meeting with the newest potential buyer, the new
owner/operator will be constructing a new source at the site. The new owner/operator has been
notified that they will need to submit an NOI application for a modification of the source. Until
then, the source will be listed as inactive.
