About this file
This document is an Appendix J Air Emission Calculations (2017) report for a proposed federal correctional facility project, detailing comprehensive air emission estimates for two alternative site locations: Payne Gap/Larson and Roxana. The calculations break down emissions across multiple construction phases and operational activities, including clearing, site preparation, gravel work, concrete work, building construction, paving, and fugitive dust emissions.
The emissions calculations cover key pollutants including VOC, CO, NOx, SO2, PM10, PM2.5, and CO2, with detailed metrics for both construction and operational stages. For Alternative 1 (Payne Gap/Larson), the total annual emissions range from 7.81 tons of VOC to 217.60 tons of PM10 in the first year, with 11,232 metric tons of CO2. The Modified Alternative 2 (Roxana) shows similar patterns, with annual emissions of 3.48 tons of VOC to 158.82 tons of PM10, and 4,644 metric tons of CO2. The document also includes calculations for emergency generators, boilers, wastewater treatment plant operations, and staff commuting emissions, providing a comprehensive environmental impact assessment for the proposed facility.
