Emissions of a single hazardous air pollutant (HAP), hydrogen chloride (HCl), exceed the major source threshold of 10 tons per year. Therefore, the facility is classified as a major source of HAPs. Estimated HCl emissions are tons per year and total HAP emissions are estimated to be tons per year. IV. APPLICABLE REGULATIONS Table 1.

The CO 2 emission from the concrete production is directly proportional to the cement content used in the concrete mix; 900 kg of CO 2 are emitted for the fabriion of every ton of cement, accounting for 88% of the emissions associated with the average concrete mix.

Due to the fact that the Como Quarry will be operated only sparingly for approximately the next two years while the crusher and asphalt plants are moved to new loctions onsite, the facility emissions will be less than 49 tons per year of Carbon Monoxide, Oxides of Nitrogen, Sulfur Dioxide, and Particulates (PM10).
