• Air Dispersion Modeling: Performed preliminary air dispersion modeling for the potential expansion of an electric generating station. Designed a meteorological monitoring network to support refined complex terrain modeling and assisted in developing permitting strategies;

​​

• Refined Health Risk Assessment: Prepared refined health risk assessments to comply with AB 2588, the California air toxic "hot spots" program, for a variety of facilities in Los Angeles, Santa Barbara, Ventura, Kern, and Monterey Counties, including a glass manufacturing plant, large fuel storage and distribution facilities, chemical plants, petroleum production facilities, a semiconductor manufacturing facility, a winery, and a major university;

​​

• Air Quality Impact Analysis: Managed air quality impact analysis task for an expansion project at a glass container manufacturer. Calculated operational emissions for the proposed expansion. Performed air dispersion modeling and health risk assessment for the project to demonstrate that impacts are below significance thresholds established by the South Coast Air Quality Management District. Results of these analyses were incorporated into the EIR prepared by the city;

​​

• HRA and AQIA: Completed a HRA and criteria pollutant ambient air impact analysis for a large scale refinery modification project in southern California that included mobile and construction emission sources;

​​

• Accidental Release Modeling: Performed accidental release modeling of a variety of regulated toxic and flammable substances at a refinery. The offsite consequence analysis included worst-case releases and alternative release scenarios. Results were incorporated into the Risk Management Plans for the facility
