Practical, Risk-Based Solutions for Complex Environmental Challenges

COMAH – Secondary and Tertiary Containment

Solutions for Complex Environmental Challenges

Environmental engineering plays a critical role in helping organisations manage risk, ensure compliance, and protect the environment. From major hazard sites to infrastructure and industrial operations, effective environmental design and management are essential to operational resilience and regulatory assurance.

Arthian provides environmental engineering services that combine technical rigour with practical delivery. We work with environmental teams to integrate environmental risk into management systems. Our approach supports compliance with PPC, IAF, EPR, COMAH, and ISO 14001, while aligning with environmental regulator expectations.

We support clients across the UK and Ireland to meet environmental obligations under planning, permitting, COMAH, and sustainability frameworks, ensuring that environmental protection is embedded into the way you design, operate, and grow.

Environmental Protection and Compliance

Environmental engineering is a key component of compliance at industrial sites. Operators must understand how process hazards could lead to environmental harm, and take steps to prevent, design out, control, and mitigate those risks. We help clients embed environmental protection into your ongoing operation, ensuring that environmental risks are not just identified, but actively managed.

Our services include:

Best Available Techniques (BAT) Assessments

Environmental Abatement and Mitigation Review

Environmental Risk Assessment for Major Accident Scenarios

Design Input for Environmentally Compliant Systems

Emergency Response and Mitigation Planning

Interface with Regulators and Stakeholders

Best Available Techniques (BAT) Assessments

We carry out systematic assessments against BAT guidelines to help clients meet environmental permitting requirements and demonstrate compliance with regulatory expectations. Our approach ensures that proposed techniques and technologies reflect the latest standards for environmental performance, resource efficiency, and pollution control. By aligning with Best Available Techniques, we support clients in making informed decisions, reducing environmental impact, and strengthening the case for approval.

Environmental Abatement and Mitigation Review

We carry out thorough evaluations of appropriate mitigation and abatement options available to a site, tailored to its specific environmental context and development scenario. Our reviews help identify practical and effective measures to reduce emissions, control pollution, and minimise environmental impact. By considering a range of site-specific solutions, we support clients in meeting regulatory requirements, improving sustainability outcomes, and making informed decisions about environmental risk management.

Environmental Risk Assessment for Major Accident Scenarios

We help clients identify environmentally significant events that could arise from major accidents, and assess their potential impacts on land, water, and air. Our assessments are tailored to the specific risks and operations of each site, supporting compliance with regulatory frameworks and informing emergency planning. By understanding the environmental consequences of worst-case scenarios, we help organisations manage risk proactively and build resilience into their operations.

Design Input for Environmentally Compliant Systems

We provide expert input to support engineering decisions that reduce environmental risk at source, helping to embed compliance and sustainability into system design from the outset. Our team works closely with designers and project engineers to identify practical, low-impact solutions that meet regulatory standards and improve environmental performance. By integrating environmental considerations into early design stages, we help clients avoid costly retrofits, streamline approvals, and deliver more resilient infrastructure.

Emergency Response and Mitigation Planning

We develop tailored environmental response strategies to help sites prepare for loss-of-containment and firewater scenarios. Our planning considers the specific risks and operations of each site, identifying practical measures to limit environmental harm and support a rapid, coordinated response. By focusing on site-specific mitigation options, we help clients strengthen resilience, meet regulatory expectations, and protect land, water, and air from potential incident impacts.

Interface with Regulators and Stakeholders

We support effective engagement with key stakeholders, including the Environment Agency (EA), Scottish Environment Protection Agency (SEPA), Natural Resources Wales (NRW), and local planning authorities. Our team helps clients navigate regulatory expectations by facilitating clear communication, aligning technical evidence with policy requirements, and ensuring that environmental submissions are well understood. By managing the interface with regulators and stakeholders, we help streamline approvals and build confidence in project delivery.
