♦ Determine the odour levels (frequency, Duration, Concentration) at sensitive receptors.

♦ Identify and rank odour sources.

♦ Differentiate the odour impact of one plant from neighboring plants.

♦ Recommend solutions for odour impact reduction.

♦ Determine efficiency of installed odour control technologies.

Field Odour Patrol is used for:

♦ Source identification: determining the sources that need to be sampled and measured using olfactometric laboratories

♦ Baseline Study: assess the plants emission at the boundary and at the sensitive receptors (neighboring residents)

♦ Contribution Study: assess the impact of other nearby odour causing industries

♦ Quality Assurance: assess the accuracy of predicted impact from dispersion model and source sampling by comparing the results to real measured field data.

♦ Determine the effect of process events (e.g. flaring) on odour impact of the plant.
