RWDI air quality services:
Regulatory Permitting
Permits, approvals and licences for provincial regulators.
Regulatory Modeling
For environmental applications, approvals and impact assessments required for new and expanded industrial facilities.
Regional Airshed Modeling
Evaluate urban smog, ground-level ozone, fine particles and deposition for urban and rural areas.
Accidental Release Modeling
Assess accidental releases from multi-phase, heavier-than-air, neutrally-buoyant, transient and steady-state releases.
Source and Emission Inventories
Identify and characterize point, line, area and mobile emission sources.
Meteorological Analysis
Review airport and site-specific meteorological data for dispersion characterization.
Climate Assessments
Assess climate for project design.
Physical Modeling
Resolve complex airflow problems through wind tunnel testing.
Technology Evaluation
