About Leak Detection and Repair (LDAR)
The U.S. Environmental Protection Agency (EPA) established Leak detection and repair (LDAR) regulations and compliance programs in order to limit the amount of volitile organic compunds (VOCs) and volitile hazardous pollutants (VHAPs) emitted by leaking equipment such as valves, pumps and connectors in industries such as petroleum refining and chemical manufacturing. The EPA requires LDAR managers technicians to follow fundamental compliance and calibration procedures to keep LDAR programs in compliance.
LDAR Program Best Practices
At a minimum, a LDAR program should schedule inspections to ensure compliance, track work orders as soon as leaks are detected, and report such leaks to the appropriate environmental agency. These best practices are streamlined with the use of automatic data capture technology, such as barcode labels and tags.

5 Components of an Effective LDAR Program
- Identifying Components
Every regulated component must have a unique identification number and an identified location. LDAR technicians should maintain an equipment log that tracks replacement parts, new equipment and equipment removed from service. ID numbers should be clearly marked on all equipment and must remain readable for the life of the equipment.
- Leak Definition
Leaks are defined as a measured concentration of a compound exceeding a standard, acceptable threshold as defined by the appropriate regulatory authority. Leaks are measured in parts per million (ppm), and different federal and state regulations have different acceptable thresholds. In some cases, multiple federal and/or state regulations may apply. In such cases, the EPA recommends defining leaks at the lowest minimally accepted threshold among the applicable regulations.
- Monitoring Components
EPA Reference Method 21 is the primary method used to monitor equipment for purposes of leak detection. Under Method 21, LDAR technicians use a portable detection instrument to evaluate emissions on a weekly, monthly, quarterly, or annual basis.
- Repairing Components
Regulatory guidelines determine when a leak must be repaired after detection. Typically, an LDAR technician must attempt to repair a leak within 5 days of detection. If the first attempt to repair is unsuccessful, the LDAR technician must make a second attempt to repair within 15 days. Asset management systems and LDAR tags can help technicians document such repair attempts, monitor equipment life cycle and conduct preventative maintenance.
Federal and state LDAR regulations have strict documentation standards and require complete and accurate records on every regulated part. An asset management system that incorporates automatic identification and data capture through the use of LDAR tags can make the record keeping and compliance process significantly faster, more accurate and less expensive.
