PERMIT REVIEW SUMMARY

Company Name:	Sunbelt Shavings Company Inc

Facility Location:	11922 Highway 21 39
Shuqualak, MS 39361

Source Number:	2000-00042

County: 		Noxubee

PROJECT DESCRIPTION

Facility produces dried pinewood shavings.  This action will modify the facility’s existing construction permit, which was originally issued on 11/20/2009, and will issue the source a Synthetic Minor Operating Permit.  

EXISTING SYNTHETIC MINOR LIMITATIONS

The source has an existing construction permit which contains a limit on production of 86,486 tons of green logs per year.  This limits the facility’s emissions of VOCs to less than the Title V thresholds.  This limit has been brought forward into the facility’s Synthetic Minor Operation Permit (SMOP).  

The PM and PM10 limits established in permits issued prior to January 1, 2011, were reevaluated to determine if they were based upon the filterable portion only or both the filterable and condensable portion. The limits were determined to be based on the filterable portion of the PM because the monitoring previously established did not require a demonstration of compliance using both a filterable and a condensable test method. As allowed under 40 CFR 52.21(b)(50)(vi), limits established prior to January 1, 2011, need not include condensable PM.  All PM/PM10 limits in the permit now indicate the portion of PM to which the limit applies.

Mississippi’s state standards for PM found in APC-S-1 were developed based upon filterable PM to ensure ambient air quality met the Total Suspended Particulate (TSP) NAAQS and were also established prior to the regulation of condensable PM.  Therefore, they are considered “filterable only” PM standards and are indicated as such in the permit.

PUBLIC PARTICIPATION

The 30-day public notice period began on May 17, 2013, with the publication of a notice in the Commercial Dispatch and ends June 16, 2013.

RECOMMENDATION

The staff has preliminarily decided to recommend issuance of the permit to the Mississippi Environmental Quality Permit Board as shown in the draft permit.  However, the staff recommendation to the Board will be made only after a thorough consideration of all public comments.
