- Updated Standards 2 and 7 Exemption and Deferral Guidelines, 11/24/2010
DHEC's Bureau of Air Quality (BAQ) is in the process of updating our Air Quality
Modeling Guidelines (Guidelines). When this process is complete, we will present our complete revisions to
stakeholders for comment. In the interim, we have revised Section 1.2, Facilities/Sources Exempt or Deferred
from Modeling, of our Guidelines and have presented these revisions to the Streamlining Stakeholders group
for comment. This stakeholder group has been involved in our streamlining process, aimed at improving
efficiency, for revising SC Regulation 61-62.1, Definitions and General Requirements. These updated modeling
exemption and deferral guidelines have been approved by BAQ management and are currently being used by them.
These revisions will be incorporated into our Guidelines, replacing the current Section 1.2, when our
revision process is complete. Click on the following link to go to this updated guidance:
