1 STATEMENT OF BASIS For the issuance ofdraft Air Permit # 1140-AOP-R4 1. PERMITTING AUTHORITY: Arkansas Department ofenvironmental Quality 5301 Northshore Drive North Little Rock, Arkansas APPLICANT: Anthony Timberlands, Incorporated 930 Cabe Street Malvern, Arkansas PERMIT WRITER: Shawn Hutchings 4. PROCESS DESCRIPTION AND NAICS CODE: NAICS Description: Sawmills NAICS Code: SUBMITTALS: 1/27/ REVIEWER'S NOTES: Anthony Timberlands, Inc. currently operates a pine sawmill located at 930 Cabe Street in Malvern, Hot Spring County, Arkansas. This permit is the renewal Title V permit for the facility. Changes in this permit include removing SN-17 the Chemical Dip Vat, and adding Roadway emissions, Logo Painting, and an Diesel Pump as SN-20, 21, and 22. Permitted emissions ofpm and VOC lowered 25.7 tpy and 2.5 tpy respectively. HCI emissions increased 5.6 tpy. 7. COMPLIANCE STATUS: The following summarizes the current compliance ofthe facility including active/pending enforcement actions and recent compliance activities and issues. There are no known enforcement issues with the facility.

2 Permit #: 1140-AOP-R4 Page 2 of6 8. PSD APPLICABILITY: a. Did the facility undergo PSD review in this permit (i.e., BACT, Modeling, etc.)? N b. Is the facility categorized as a major source for PSD? N Single pollutant ~ 100 tpy and on the list 0/28 or single pollutant ~ 250 tpy and not on list? Ifyes, explain why this permit modification is not PSD? 9. SOURCE AND POLLUTANT SPECIFIC REGULATORY APPLICABILITY: Source Regulation (NSPS, NESHAP or PSD) 18 and 19 PM CAM 22 HAPs MACTZZZZ 10. EMISSION CHANGES AND FEE CALCULATION: See emission change and fee calculation spreadsheet in Appendix A. 11. MODELING: Criteria s Emission Rate (lb/hr) NAAQS Highest Standard Averaging Time Concentration (llg/ m3 ) (llg/ m3 ) %of NAAQS PM Hour % CO ,000 8-Hour 52 >1% 40,000 I-Hour 84 >1% Rolling 3-month Period over 3 Pb years (not to be I-month >1% exceeded in any 3 month period) Non-Criteria s: 1st Tier Screening (PAER) Estimated hourly emissions from the following sources were compared to the Presumptively Acceptable Emission Rate (PAER) for each compound. The Department

3 Permit #: 1140-AOP-R4 Page 3 of6 has deemed the PAER to be the product, in Ib/hr, of0.11 and the Threshold Limit Value (mg/m\ as listed by the American Conference of Governmental Industrial Hygienists (ACGIH). TLV PAER (lb/hr) = (mg/m 3 ) 0.11 x TLV Proposed Ib/hr Pass? Acrolein N Anthracene Y Arsenic N Benzene N Cadmium Y Chromium Y Ethylbenzene Y Fluorene {)42 y Formaldehyde N Hexane Y Hydrogen Chloride N Manganese N Methanol y Mercury Y MTBE Y Phenathrene Y Phenol y Pyrene Y Styrene Y Toluene Y Xylene Y 2 nd Tier Screening (PAIL) AERMOD air dispersion modeling was performed on the estimated hourly emissions from the following sources, in order to predict ambient concentrations beyond the property boundary. The Presumptively Acceptable Impact Level (PAIL) for each compound has been deemed by the Department to be one one-hundredth ofthe Threshold Limit Value as listed by the ACGIH. For Benzene the permittee submitted modeling based on the REL established by the California State Office ofenvironmental health Hazard Assessment, which has acute (6hr) and chronic (l yr) standards. PAIL (llg/m3) = 1/100 of Modeled Concentration Threshold Limit Value (ug/m3) Pass? Acrolein y Arsenic Y
