Our Services
Viterstream assists clients with regulatory permitting, primarily in British Columbia (including Metro Vancouver, a separate jurisdiction) but also in other provinces of Canada. This includes engagement with the regulator as well as other stakeholders, facility emissions assessment and atmospheric dispersion modelling if needed.
Air quality analysis for both government and industrial clients, addressing emissions modelling for all transportation categories (onroad, offroad, marine, rail, aircraft), as well as stationary and industrial sources. Both fossil fuels and biofuels can be characterized for their emissions and GHG profiles. Much of our work in this space involves developing emission inventories for industry waste discharge permits or for project environmental impact assessment.
Viterstream conducts both meteorological and ambient air quality monitoring on behalf of clients, mostly for project development (environmental impact assessment). Our services include equipment procurement, station setup and management, data analysis and related reporting.
Meteorological modelling for wind flow and other climatic conditions in remote areas as well as evaluation of existing monitoring data for extreme weather occurrence and return events (precipitation, high magnitude winds).
Climate analysis, including potential future climates as well as climate risk studies following frameworks such as Climate Lens (Government of Canada) and the Public Infrastructure Engineering Vulnerability Committee (PIEVC) Protocol.
Simulation of accidental releases of hazardous gases (e.g., propane, chlorine) to evaluate threat zones, often in support of emergency response planning, regulatory compliance and risk management.
Viterstream staff have completed peer review studies of the meteorological and air quality aspects of major projects, including review of air emissions, atmospheric modelling, emissions controls and potential impacts. Viterstream staff also have experience participating in expert panel reviews of regulatory permit applications or amendments, providing technical input on air quality and emissions-related considerations.
Viterstream can help clients fulfill all regulatory air quality-related requirements, including development of air quality management plans, fugitive dust management plans and annual air quality reporting.
About Viterstream
Viterstream was founded by Bryan McEwen in 2022.
Viterstream provides atmospheric science services to industry and government clients, covering a wide variety of needs, including regulatory permitting, air quality monitoring and modelling, meteorological monitoring, climate studies, air hazard assessment, air emissions assessment (criteria air contaminants, GHGs, air toxics), carbon-neutral planning, and peer review.
While physically located in Vancouver, B.C., Viterstream has conducted work across Canada and has practical working experience in most Canadian jurisdictions.
Viterstream staff have particular knowledge of port and marine operations, having built several energy and emissions models for the Canadian government. Some of these are used for ongoing projects, as identified on our Projects and Products page.
