Notice of Proposed Air Permit for Prevention of Significant Deterioration (PSD)
and Request For Comments
Facility No. 210-S006


On April 25, 2018, Rex Lumber, Troy, LLC submitted a complete Prevention of Significant Deterioration (PSD) Permit application for for the proposed construction and operation of a sawmill. This facility is located at 1946 County Road 7714 in Troy, Alabama.

The proposed modification is subject to the requirements of the Prevention of Significant Deterioration (PSD) regulations as set forth in ADEM Admin. Code r. 335-3-14-.04.  An ADEM-Air Division technical staff preliminary determination indicates:

  1. Best Available Control Technology (BACT) is represented for control of nitrogen oxides (NOx), particulate matter (PM), volatile organic compounds (VOC) and Greenhouse Gases (CO2e).  In determining BACT, the Department considered the impact of the control technology on air pollutants that may be emitted by the source including those not regulated by the Clean Air Act.  A discussion of how BACT was determined is included in the Department’s preliminary determination.

  2. The source is located approximately 220 kilometers from the Bradwell Bay Wilderness Area (a federal PSD Class I area). This proposed project would consume the following increments:

  3. Pollutant

    Class I Increment

    Class II Increment

    PM10, 24-hour



    PM10, Annual



    PM2.5, 24-hour



    PM2.5, Annual



    NO2, Annual



  4. The maximum combined pollutant concentration from Rex Lumber, Troy, LLC would be less than the National Ambient Air Quality Standards (NAAQS).  The NAAQS are levels set by the Environmental Protection Agency which identify the ambient concentration necessary to protect human health and welfare with an adequate margin of safety.

ADEM has determined that the limitations proposed by the company would properly limit emissions.
