Success Story

Manufacturing Facility in Denver, Colorado


Personnel turnovers and a loss of institutional knowledge at the site created problems when the facility needed to make changes to their air permit. Not understanding the RACT requirements that come into play for permit modifications in non-attainment areas, they reached out to Array for help.



Array reviewed the facility’s historic information, including previously rejected air pollution emission notices (APENs); interviewed personnel; and conducted a site visit to understand the emission sources present. Based on this information, we were able to submit revised APENs and a RACT analysis with a limited scope of control technology options. Having conversations with the Division at the beginning of the project fostered these important relationships, cleared up some previously confusing correspondence, and enabled both parties to have a clear view of the scope, which ultimately saved our client time and money.
