TEC is experienced with the Environmental Protection Agency's (EPA) mobile source emissions modeling procedures, including MOBILE 6 and CAL3QHC, and has assisted with evaluating conformity requirements for transportation projects. The firm has prepared numerous intersection-specific air-quality impact studies for public highway projects and private clients to evaluate development-related carbon monoxide (CO) impacts. TEC is experienced with “emissions inventories” to quantify area-wide emissions of CO and other pollutants, for example as related to land-use and transportation plans. The firm has also implemented the Federal Aviation Administration (FAA) air-quality Emissions and Dispersion Modeling System (EDMS) to evaluate the air-quality effects of aircraft.
Air Quality Plan: Mesa del Sol, Albuquerque State Land Office, 1997
The Mesa del Sol Community Master Plan provided unique opportunities to enact transportation-related policies and land-use strategies that would reduce travel in single occupancy vehicles, thus making the street system more efficient and reducing air pollution. An air-quality analysis was prepared to explore these opportunities for the 13,000-acre Mesa del Sol plan area in Albuquerque, NM. The analysis evaluated neighborhood design concepts and a variety of other multimodal transportation strategies that reduce travel and related emissions, including a highly interconnected street system, pedestrian and bicycle facilities, mixed-use development, concentrated activity centers, transit-oriented design, and optimum connections to the regional road system.
Air Quality Analysis: Albuquerque International Airport, Coffman Airport Consultants for City of Albuquerque Aviation Department, 1994-1997
TEC prepared an air-quality analysis for the expansion of the Airport, in conjunction with the FAA. The project required implementation of the FAA's air-quality EDMS model, which resulted in estimates of existing and future emissions from aircraft operations. The analysis showed a net improvement in air quality because aircraft queuing time and related high emissions would decline with multiple runway operations. The project was controversial and involved lengthy testimony before the Albuquerque City Council; however, the analysis stood up to careful review. Subsequently TEC performed an additional air analysis of the landside transportation system, including taxis, rent-a-car facilities, buses, and the multilayered ramp system for arriving and departing passengers.
Air Quality Impact Analyses (AQIAs): Albuquerque, NM, Private developers for City of Albuquerque Environmental Health Department, 1994-99
TEC has performed numerous AQIAs for development projects in the Bernalillo County CO “maintenance” area. These projects were performed for the City of Albuquerque Environmental Health Department to comply with the City’s zoning code. Projects were conducted according to Environmental Protection Agency (EPA) guidelines for CO "hot spot" analyses using EPA’s most recent mobile source emissions model (MOBILE) and CO dispersion model (CAL3QHC). Several studies also included inventories to estimate quantities of emissions.
