Prevention of Significant Deterioration (PSD) requirements shall apply to this source at <br />any such time that this source becomes major for PSD solely by virtue of a relaxation in <br />any permit condition. Any relaxation that increases the potential to emit above the <br />applicable PSD threshold will require a full PSD review of the source as though <br />construction had not yet commenced on the source. The source shall not exceed the PSD <br />threshold until a PSD permit is granted. (Reference: Regulation No.3, Part D, Section <br />V 1.13.4.) <br />9.

This source shall be limited to a maximum production rate as listed below and all other <br />activities, operational rates and numbers of equipment as stated in the application. <br />Compliance with the yearly production limits shall be determined on a rolling twelve (12) <br />month total. Annual records of the actual production rate shall be maintained by the <br />applicant and made available to the Division for inspection upon request. (Reference: <br />Regulation No. 3, Part B, Section II.A.4.) <br />Production of hot mix asphalt concrete shall not exceed 580,000 tons per year. <br />Materials handled shall not exceed those corresponding to the production limit. <br />Recycled asphalt concrete used shall not exceed 40 % of the production. <br />10.
