New ADBA Operational Guidance Note for Leak Detection and Repair

ADBA has published a new Operational Guidance Note (OGN), outlining essential steps to mitigate fugitive emissions and enhance biogas plant resilience through effective Leak Detection and Repair (LDAR) programmes.

Conducting LDAR is crucial for maintaining site integrity while minimising potential explosive gas leaks that threaten both the environment and staff safety.

Studies show that 85% of biogas plants suffer from gas leaks, potentially losing 1m³ of methane per hour and approximately £5,000 annually, proving that implementing a proper LDAR program is not just about regulatory compliance but also operational efficiency.

This OGN details how to establish a systematic approach for identifying, monitoring, and fixing leaks of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs).

A successful LDAR programme depends on quality record-keeping, operator competency, proper monitoring equipment, comprehensive component assessment, regular surveys, and timely repairs.

Every plant should implement a LDAR programme on their facility to ensure meeting regulatory requirements and maximising performance and safety.
