AMI has considerable experience in performing hazard/risk assessment studies of accidental releases of toxic pollutants and other hazardous materials, including the preparation of Risk Management Plans (RMP). AMI principals have the expertise to serve as expert witness in litigation cases. AMI has in-house computerized models which can predict the consequences and fate of hazardous chemicals released in the air, water and soil environments. Hazard assessment models for air toxics operational on AMI's in-house computers include ALOHA, CAMEO, PUFF, TSCREEN and INPUFF developed by the EPA, the AFTOX, DEGADIS, SLAB and SPILLS models. Representative projects performed by AMI include the following:
 

Hazard Assessment of Accidental Releases from Ethanol Production Plant

For the California Energy Commission, AMI conducted a detailed modeling assessment to derive hazard footprints of accidental releases of chlorine and hydrazine. The TSCREEN model was used for instantaneous and continuous releases. Dense gas dispersion was analyzed with the DEGADIS model. This modeling study was performed as part of the AFC review of a proposed ethanol production facility in Sacramento.
 

Risk Management Plan of Accidental Releases of Ammonia

AMI recently completed a detailed modeling assessment to derive hazard footprints of accidental releases of anhydrous ammonia. The ALOHA/CAMEO models were used for several release scenarios. This modeling study was performed as part of an Offsite Consequence Analysis of the Risk Management Plan (RMP) for an industrial facility in Los Angeles.
 

Toxic Releases from Rocket Launches at Vandenberg AFB

For the U.S. Air Force, AMI staff conducted an atmospheric dispersion modeling of toxic chlorine gas released from launches of space vehicles at Vandenberg AFB. This study involved the use of the three-dimensional grid model IMPACT since the potential zone of impact is located in complex terrain. The model was applied to actual launches and its predictions were compared against actual field measurements.
 

Accidental Releases of Flammable and Toxic Materials from a Fueling Pier

As part of an EIS prepared for the U.S. Navy, AMI staff used the SPILLS model and risk management procedures to derive hazard footprints of potential accidents at a fueling pier located at the U.S. Navy Mole in Long Beach, California. Potential spills of flammable fuels and toxic chemicals during their transport, storage and fueling operations were evaluated.
 

Accidental Releases of Toxic Materials from Chemical Plants

AMI conducted a detailed modeling assessment of the effects at proposed school sites from potential releases of toxic chemicals. Instantaneous releases were analyzed with the EPA's PUFF model and several regulatory models (e.g., SCREEN, ISCST and PTDIS) were used for continuous releases. This study was performed as part of a siting study for the Los Angeles Unified School District.
 

Computerized Environmental Information System

Under contract to the U.S. Air Force Engineering Services Center, AMI developed and evaluated a prototype environmental model and data exchange system. AMI designed the hardware and software of a computer system which allows Air Force personnel to access environmental models and data bases for spill hazard assessment, air and water pollution modeling. The system was installed at Randolph AFB and AMI also provided training to Air Force's environmental planning staff.
