Company Martin Marietta Materials Location Highway 34 facility S. half of Sec 18, T 5N, R 67W Permit # 16WE0688 AIRS ID 123/9E8B/001 Engineer KC Houlden Application date 5/23/2016 PA date 8/12/2016 Concrete batch plant Notes Source is a true minor source at a true minor facility. The PTE emissions for the facility are based on 2920 hours of operation per year, one third of 8760. It is unreasonable to assume a concrete batch plant would run an operation at design rate 8760 hours per year due to both the possiblity of demand and the logistics of moving the conrete at that rate. It is equally unreasonable to assume that aggregate could be delivered at the maximum rate of 900 tons per hour by railcar for 8760 consecutive hours, so PTE is considered to be the uncontrolled requested which is one third of 8760. Fugitive dust and point PM is not considered in determining major source status, so this facility is considered a synthetic minor. Due to a large public interest in this project, however, the Division is sending this permit and permit 16WE0689 to public comment.

COLORADO Air Pollution Control Division Page 8 of 8 Company Martin Marietta Materials Location Highway 34 facility S. half of Sec 18, T 5N, R 67W Permit # 16WE0689 AIRS ID 123/9E8B/002 Engineer KC Houlden Application date 5/23/2016 PA date 8/12/2016 Aggregate transload facility Notes Source is a true minor source at a true minor facility. The PTE emissions for the facility are based on 2920 hours of operation per year, one third of 8760. It is unreasonable to assume a concrete batch plant would run an operation at design rate 8760 hours per year due to both the possiblity of demand and the logistics of moving the conrete at that rate. It is equally unreasonable to assume that aggregate could be delivered at the maximum rate of 900 tons per hour by railcar for 8760 consecutive hours, so PTE is considered to be the uncontrolled requested which is one third of 8760. Fugitive dust and point PM is not considered in determining major source status, so this facility is considered a synthetic minor. Due to a large public interest in this project, however, the Division is sending this permit and permit 16WE0689 to public comment.
