Health Risk Assessments (HRAs)

Need a cost-effective health risk assessment and options for reducing calculated risks? We apply our experience in dispersion modeling and risk assessment to minimize risk impacts including process changes or controls options to reduce calculated risks

ArrowTek prepares risk assessments that meet the following regulatory requirements:

• California's Toxics Hot Spots (AB 2588) Program (health risk estimates)
• New/modified source permitting (T-BACT reviews)
• CEQA analyses for capital projects (significance findings)
• Public noticing (public notice requirements)

We prepare HRA's and follow protocols set by:

• California Office of Environmental Health Hazard Assessment (OEHHA) Risk Assessment Guidelines
• California Air Pollution Control Officers Association (CAPCOA)/ARB Risk Management Guidance for Stationary Sources of Air Toxics
• ARB Hotspots Analysis and Reporting Program (HARP2)

Available outputs and risk characterization:

• Various outputs in AERMOD plot file format
• Single receptors by chemical
• Risk contours over entire receptor field
• KML files for import to Google Earth
• Cancer burden and population exposures
