We prepare Air Toxics Inventory Reports (ATIRs), Toxic Emission Inventory Plans and Reports (TEIP/TEIR), and other state- or district-specific submittals, ensuring compliance with reporting requirements.

Our team conducts HRAs using tools such as CARB’s HARP 2.0 and U.S. EPA’s HHRAP protocols, including multi-pathway analyses for carcinogenic, acute, and chronic health effects.

We apply models such as AERMOD, CALPUFF, and BREEZE Risk Analyst to simulate pollutant dispersion and evaluate population exposure under varying conditions.

We develop Risk Reduction Plans (RRPs) and support participation in voluntary programs, such as SCAQMD’s Rule 1402, to reduce health risks and strengthen community trust.

Trinity prepares public notification packages and provides support during public meetings for facilities with elevated risk levels, promoting transparency and compliance.

We integrate advanced modeling and GIS tools to streamline data handling, improve accuracy, and visualize health risk results in clear, actionable formats.
