DiGiSci are environmental impact assessment consultants and are world-leaders, among environmental assessment companies, in air quality impact assessments required for EAs. Senior Project Manager at DiGiSci, Dr. Franco DiGiovanni, is first author of the international standard guideline on air quality impact assessments: Guiding Principles for Air Quality Assessment Components of Environmental Impact Assessments

As well as providing world-class expertise in air quality, we can also assist in Terms of Reference development and provide expertise in many of the other disciplines involved (First Nations liaison, economic impacts, water pollution assessments, social impacts, etc.) to provide a turn-key solution to your environmental assessment consultant needs.

We have experience in conducting comprehensive air quality impact assessments including developing emission inventories for various scenarios, applying dispersion modelling, assessing background (baseline) levels for target contaminants (including measurement where necessary) and providing detailed reports. When necessary, we work with consultants from other fields to ensure that the air quality component of the assessment is consistent with the other elements of the project.

DiGiSci has over 20 years of experience in EAs, including experience before Federal Review Panels. Staff members are leaders in the field of identifying potential public health impacts liabilities for proponents.

How we help you in environmental impact assessment:

  • Step 1 – We have an initial consultation with the client – this enables us to provide a cost estimate for the work.
  • Step 2 – (If required) Provide assistance with Terms of Reference developments.
  • Step 3 – Develop appropriate, worst-case, emissions scenarios.
  • Step 4 – Provide upper limit air pollution increments in the surrounding areas.
  • Step 5 – Develop a valid database on baseline air quality in the area surrounding your project.
  • Step 6 – Combine air pollution increments with baseline data to provide cumulative air quality levels.
  • Step 7 – Compare results to air quality standards and/or provide results to (and work with) health impact experts.
  • Step 8 – Problematic results can be either (i) refined, and/or (ii) mitigations can be suggested.
