Repair requirements and new challenges in managing methane emissions

The new EU Methane Regulation introduces mandatory measures for the oil and gas industry to detect and repair methane emissions under the Leak Detection and Repair (LDAR) program. This regulation builds on best practices like OGMP 2.0 but imposes much stricter requirements for methane reduction. A key aspect is the repair process, which is detailed in Article 14. This article outlines the process for leak detection, repair, and the monitoring of implemented measures.

The LDAR program (Leak Detection and Repair) is a significant component of the new EU Methane Regulation. It requires operators to carry out regular inspections of their facilities to identify and immediately fix methane leaks.

Leaks Exceeding Repair Thresholds

The regulation sets a repair threshold of 500 ppm or 1 g/h for above-ground components, 1000 ppm or 5 g/h for underground components, and 7000 ppm or 17 g/h for subsea offshore components. (Art. 14 § 8)

The repair process is clearly outlined: If a leak exceeding the respective threshold is detected, immediate repair is required. If an immediate repair is not possible, an initial repair attempt must be made within 5 days, and the repair must be completed within 30 days. In exceptional cases, the regulation allows for a delay, which must be justified by the operator and approved by the relevant authorities. Various reasons for the delay are outlined in the regulation and must be evaluated on a case-by-case basis. (Art. 14 § 9)

Leaks Below Repair Thresholds

Leaks below the respective repair thresholds, such as 300 ppm for above-ground components, do not require immediate repair. These leaks must be monitored in quarterly campaigns to ensure that their condition does not worsen. If the leak exceeds the repair threshold, the same process applies as for leaks above the threshold.

Validation, Prioritization, and Long-term Documentation

Another aspect of the new regulation is the follow-up after repair. At least two monitoring measurements must be conducted: one immediately after the repair and another within 45 days. These checks are necessary to ensure that the leak has been completely fixed and that the repair is sustainable. (Art. 14 § 12a)

The regulation also emphasizes that larger leaks, which have higher emission potential, must be prioritized. Operators are required to document their actions, report to the authorities, and keep these records for at least 10 years. This ensures traceability and long-term transparency. (Art. 14 § 13)

Conclusion

The EU Methane Regulation sets clear thresholds for leak detection and imposes strict deadlines for repair. The focus is on immediate repair and long-term monitoring to reduce methane emissions not only in the short term but also sustainably. The clear prioritization of larger leaks and regular inspections help ensure compliance with the new regulation and contribute to climate protection.

For companies, this represents an administrative and organizational challenge. It requires a systematic approach and the implementation of effective systems to significantly reduce the burden on operators.
