LDAR Testing
Leak Detection and Repair

What is LDAR and Why is it Important?

Fugitive emissions of volatile organic compounds (VOCs) represent a significant industrial challenge, originating mainly from leaks in pipelines, valves, and other equipment components. These emissions can be substantially reduced through the implementation of an LDAR – Leak Detection and Repair – program aimed at identifying and promptly repairing leaks.
LDAR is a proactive approach that involves systematic detection of leaks using precise measurements and the repair of leaking components. Through a structured LDAR methodology, facilities can significantly reduce VOC emissions, improve air quality, and comply with strict environmental regulations.
Ecological Laboratories A.P. Ltd. implements LDAR programs using the advanced Manager Leaks system, a dedicated software platform for managing and monitoring leaks efficiently. The system’s flexibility allows full customization to each client’s needs while maintaining complete compliance with Ministry of Environmental Protection requirements. By combining advanced technology with extensive professional experience, the company helps its clients maintain clean operations, regulatory compliance, and a reduced environmental footprint.

Sampling and Testing Process

1. Building and updating the list of components
2. Marking components on P&ID diagrams
3. Preparing a monitoring plan for submission to the Ministry of Environmental Protection
4. Conducting field measurements using accurate and calibrated instruments
5. Producing detailed summary reports
6. Providing ongoing professional support and client guidance throughout the process

Frequently Asked Questions

• What is LDAR and why is it essential?
  • LDAR is a systematic process for detecting and repairing leaks of volatile organic compounds (VOCs) from industrial equipment components. Proper implementation reduces air emissions, improves environmental quality, and supports compliance with regulatory requirements.
• Which standards and procedures are used for LDAR testing?
  • Testing is conducted in accordance with EPA Method 21, the LDAR Procedure (2024), and international protocols for VOC emissions, under ISO 17025 accreditation.
• Who is authorized to perform LDAR testing?
  • LDAR testing is carried out by certified field teams of Ecological Laboratories A.P. Ltd., officially recognized by the Ministry of Environmental Protection and experienced in conducting measurements since 2009.
• What does the LDAR testing process at an industrial facility include?
  • Compilation of an equipment component list, marking components on P&ID diagrams, preparation of a monitoring plan for submission, calibrated field measurements, and generation of detailed summary reports.
• What types of leaks can be detected?
  • Leaks can be detected from regulators, valves, pumps, flanges, welds, fan systems, and additional equipment components where VOC transfer may occur.
• What is the Manager Leaks system and how does it help?
  • It is a dedicated system for leak management and control, enabling documentation, tracking, data analysis, and full alignment with the regulatory requirements of the Ministry of Environmental Protection.
• What is included in the summary reports provided to the client?
  • The reports include measurement results, documentation of leak locations, findings analysis, emission estimates, and recommendations for repair and process improvement.
