After the first twelve (12) months of operation, compliance with only the <br />yearly limitation shall be required. <br />Compliance with the annual limits shall be determined by recording the facility's annual emissions for the <br />pollutants listed in the table above on a rolling twelve (12) month total. By the end of each month a new <br />twelve-month total shall be calculated based on the previous twelve months' data. The permit holder shall <br />calculate monthly emissions and keep a compliance record on site, or at a local field office with site <br />responsibility, for Division review. <br />The source accurately tracks emissions on a monthly and rolling 12 -month total using the emission <br />factor in the Notes to Permit Holder section of the permit. The facility maintained compliance with <br />the monthly limits during the first year following permit issuance, and operated in compliance with <br />the rolling 12 -month total during the compliance period (see attached records). The highest <br />reported rolling 12 -month total PM, PMjo, and PM2.5 emissions for this point occurred during the <br />period ending March 2014, with 0.76 tpy, 0.042 tpy, and 0.042 tpy respectively. The source is in <br />compliance with this condition. <br />2. The following control equipment shall be maintained and operated to achieve the control <br />efficiencies listed below. The owner or operator shall monitor compliance with this condition through the <br />results of approved compliance tests (when required), compliance with the Operating and Maintenance <br />Plan, compliance records, and other methods as approved by the Division.

Weekly and monthly silo baghouse maintenance and <br />inspection records were provided and reviewed as part of this inspection. Maintenance personnel <br />appeared to accurately record when preventative or corrective maintenance was conducted, as <br />required. According to source records, bags were replaced on 5/7/2015. Without evidence to suggest <br />the contrary, the source is in compliance with this condition. <br />PROCESS LIMITATIONS AND RECORDS <br />This source shall be limited to the following maximum consumption, processing and/or operational rates <br />as listed below.
