Air quality requirements are becoming a critical factor in project approvals, and increasingly a source of delay where expectations are not met. If your project involves emissions, odour, dust, or community sensitivity, a well-designed air quality approach can be the difference between a smooth approval and costly rework. PJRA supports developers, operators, and planners to deliver practical, regulator-ready air quality assessments that stand up to scrutiny.

When This Service Is Relevant

This service is likely relevant if you are:

• Planning or modifying a development requiring EPA or council approval

• Managing emissions, odour or dust complaints
• Reviewing or updating an existing air quality assessment
• Investigating process improvements or emission control performance
• Working on projects in sensitive or highly regulated environments

Air Quality Impact Assessment & Management

We design and deliver air quality assessments across a wide range of industries, including:

• Manufacturing and industrial processing
• Waste management and waste-to-energy
• Mining and extractive industries
• Renewable fuels and energy
• Food production and chemical processing

Our work supports both new developments and existing operations, helping clients meet regulatory requirements while managing community and environmental impact risks.

Air Dispersion Modelling

We use advanced air dispersion modelling to predict how emissions behave under real-world conditions and to demonstrate compliance with regulatory criteria.
Our modelling supports:

• Development approvals and licensing
• Pollution reduction strategies
• Investigation of complaints or incidents
• Assessment of alternative operating scenarios

Where required, we incorporate site-specific meteorology and complex terrain effects to improve accuracy and defensibility.
 

Particulate & Dust Assessments

Particulate emissions, including PM10, PM2.5 and respirable crystalline silica, can pose both health risks and community amenity issues.

We support clients by:

• Assessing potential dust impacts
• Designing and implementing monitoring programs
• Interpreting monitoring data
• Developing best-practice dust management strategies
   

Odour Assessment & Management

Odour is one of the most common drivers of community complaints and regulatory scrutiny. We assist clients to:

• Identify and characterise odour sources
• Assess potential impacts at sensitive locations
• Develop practical odour mitigation strategies
• Support compliance and community engagement

We have delivered odour assessments across a wide range of sectors, including wastewater treatment, rendering, agriculture, food processing, and manufacturing facilities.

Recent Project Experience

Our Technical Capability

Our team applies advanced tools and methodologies where appropriate, including:

• Regulatory dispersion modelling (AERMOD and equivalent)
• Site-specific meteorological modelling
• Field odour assessment in accordance with AS/NZS standards

We focus on selecting the right level of analysis for each project, balancing technical rigour with practical outcomes.
 

Not Sure If Your Approach Will Meet Current Requirements?

A lot of projects encounter delays because air quality expectations are identified too late.

We can provide a quick review of your air quality approach to identify potential gaps and risks before they become an issue.
