Air Quality

The SLR Air Quality, Dust and Odour team consists of over 70 specialist consultants operating worldwide providing air quality advice to clients across SLR’s seven core sectors.

The global air quality team has experience with the assessment of impacts associated across all business sectors including: urban renewal and development (residential, industrial and retail), quarrying and mining, petrochemicals, transport and infrastructure, renewable energy, oil and gas, intensive agriculture, waste management and wastewater treatment.

With our specialist in-house expertise, members of the SLR air quality team are able to undertake a full compliance/best practice assessment of an existing installation or help to support planning decisions regarding new development and the impact of change of land-use.

Whether your project involves simple screening of impacts or detailed atmospheric dispersion modelling, the SLR air quality team has the staff and experience to meet your needs.

Adequate Design Evaluation for Vapor Collection & Control Systems

SLR’s proprietary Excel-based transient model is capable of predicting and trending tank system pressure over time to determine if pressure relief set points will be exceeded.

Air Dispersion Modeling

​Air dispersion models are important tools in air quality management that are used to estimate a source or facility’s air quality impact due to its emissions.

Air Quality Impact Assessment

Managing air quality is an important index for promoting sustainable development. Air pollution occurs when impurities are released in the air, either from natural or man-made (anthropogenic) sources. Our team provides expert advice across a wide range of services, covering all aspects of air quality assessment, and the sustainable management of operations.

Air Toxics Health Risk Assessment

SLR’s scientists and engineers are experts in developing air toxics inventories and applying agency-approved models to characterize health risks.

Air quality in the intensive animal industry

Intensive Animal Industries have the potential to generate emissions of dust and odour that can adversely impact the surrounding community. We have extensive experience in odour and dust assessments, having performed numerous impact studies for a range of intensive livestock operations including broiler farms, cattle feedlots and piggeries. SLR uses best practice techniques to model odour dispersion and dust concentration levels.

Air quality services for quarries

Fugitive dust emissions from quarrying activities such as blasting, crushing, screening, stockpiling and haulage have the potential to result in health or nuisance impacts in the surrounding community and potentially result in complaints from members of the public or regulatory actions. SLR uses best practice techniques to quantify and model dust emissions from fugitive dust sources.

Ambient Air Monitoring

SLR’s team of experts have decades of extensive regulatory and dispersion modeling experience.

Ambient Air Quality

Ambient air quality refers to the quality of air in or surrounding environment. It is typically measured at locations that are sensitive to changes in air pollutant concentrations. Whether they are associated with surrounding neighbours, sensitive groups, such as the elderly or sick, or sensitive natural environments. SLR have extensive experience in the design, installation and generation of ambient air quality monitoring programs across the Asia Pacific region.

Emissions Measurements

Through evaluation of client’s regulatory compliance requirements SLR is able to design a protocol, execute field measurements, interpret results, and report the findings in a proficient format.

Leak Detection and Repair (LDAR) Programs

​With the increased use of optical gas imaging techniques SLR provides leak detection and repair (LDAR) support to all facets of the oil and gas industry.


PLUMECAST is a risk management tool designed to improve site safety, increase productivity and minimise the risk of off-site impacts. Predicting optimum timing for blasting provides the opportunity to reduce downtime, thereby increasing profitability. PLUMECAST can also be used to provide evidence to regulators and other key external stakeholders, such as community groups, of the use of best practice blasting management tools for minimising off-site impacts.

Process Emissions Monitoring

Quantifying process emissions is essential to managing compliance risks, minimising the potential for off-site air quality impacts and ensuring processes are effectively balanced.

Process Simulation Modeling

SLR holds a license for the BRE ProMax® process simulation software. Our practiced engineers combine their knowledge of process engineering and air quality regulations to confirm the process model predicts regulatory compliance with accurate model results.
