Conestoga-Rovers & Associates (CRA) will be leading three sessions under the categories of clean technology and hazardous materials at the upcoming 2012 International Sites and Spills Expo in Toronto.
CRA is an international engineering, environmental, construction, and IT services associates group with offices around the globe. On November 7, 2012, CRA representatives will be in the Toronto area to lead discussions on Useful Calculations for Hazardous Materials Responders, Comprehensive Air Monitoring Strategies During Environmental Spill and Cleanup Projects, and Evaluating the Mobility, Stability and Recoverability of a Petroleum Free Product Plume.
CRA chemical engineer Dyron Hamlin is scheduled to lead two of CRA's three talks at Sites and Spills. He’s responded on-site to more than 50 major hazardous materials emergencies, and has performed dispersion modeling remotely for more than 100 chemical releases and release prevention scenarios.
Hamlin will use a checklist to help explain important components of an air monitoring strategy to the expo:
• When: Emergency and/or remediation phase monitoring
• What: Applicable standards and guidelines – emergency v. chronic
• How: Air monitoring methods
• Who: Relevant regulatory agencies
• Why: When to scale up, when to scale down
• Where: How receptors can affect sample location selection
Hamlin will also lead the “Useful Calculations” session. A sample of the questions he will tackle includes: When hazardous materials are released, certain questions invariably arise which may be answered using relatively simple calculations. What is the highest concentration of gas to which I might be exposed? How much base is needed to neutralize this acid? What is the release rate of this pooled chemical? What air concentration is safe to breathe over this shortened time period of exposure?
Also representing CRA will be Matt Rousseau, a senior engineer and light nonaqueous phase liquid (LNAPL) technical specialist. Rosseau will examine the importance of developing a complete and technically sound LNAPL conceptual site model (LCSM) to be used as the basis for LNAPL corrective action decisions.
