Emissions Testing

LEHDER’s Emissions Testing Team is one of the largest and most experienced in Canada, recognized by Canadian and U.S. regulatory agencies. 

Although tailored to provide high-grade industrial emissions testing services for compliance purposes, many projects conducted by LEHDER are related to the development of process-specific pollutant emission factors for various inventories and Approval applications. These large projects often involve simultaneous testing and the deployment of multiple field crews.

LEHDER's comprehensive Air Quality Management services also include Odor Investigations, Dispersion Modeling and Applications for Licenses, Permits and Environmental Compliance Approvals.

Compliance Emissions Testing

Compliance Emissions Testing

Compliance Emissions Testing

Compliance Emissions Testing (CET) is typically a requirement of an approval, operating permit or pertinent regulation. A test protocol or "intent to test" must be completed by the testing firm and submitted to the appropriate regulatory agency for review and acceptance.

CEM programs are performed to evaluate process performance and efficiency over time in addition to regulatory compliance. Changes in process operation, which effect emissions, are indicated immediately by the CEM system; simultaneous manual flow measurements allow you the ability to calculate emission rates in real time.

With new regulations involving emissions trading and reporting, the validity of facility emission data is extremely important. A RATA or Relative Accuracy Test Audit compares data from a facility Continuous Emissions Monitor (CEM) system to independent Reference Method data.

Emission Inventories and Process Analysis

Emission Inventories and Process Analysis

Much of the Source Emissions Testing conducted by LEHDER for industry is to support various emission inventories and process analyses. It is important for an industrial facility to be fully cognizant of its air emissions.
