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
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
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
