Regulation (EU)

Leak Detection and Repair (LDAR) Framework
Regulation (EU) 2024/1787 establishes strict rules for the accurate measurement, monitoring, and reduction of energy-sector methane emissions within the Union. A core mechanism of this regulation is the mandatory implementation of Leak Detection and Repair (LDAR) programs designed to identify and eliminate unintentional gas leaks.

LDAR Survey Classifications & Thresholds
Operators are required to conduct periodic surveys using two distinct types of LDAR, differentiated by their required technology sensitivity and targeted methane emission thresholds. All components found leaking at or above these thresholds must be repaired or replaced immediately or within highly rigid, legally mandated timelines.

Type 1 LDAR Surveys

• Purpose: High-level screen intended to quickly flag significant emission sources using localized detection devices.
• Mandatory Methane Detection Threshold: 7,000 ppm (parts per million) in volume, OR 17 g/h (grams per hour) of methane.

Type 2 LDAR Surveys

• Purpose: Highly sensitive inspection requiring localized devices capable of finding micro-leaks across diverse operating environments.
• Mandatory Methane Detection Thresholds by Component Type:
  • Aboveground and Offshore (Above Sea Level): 500 in volume OR 1 g/h of methane.
  • Underground (Second Step): 1,000 ppm in volume OR 5 g/h of methane. (Underground surveying uses a two-step approach: an initial perimeter screening at the ground-atmosphere interface, followed by close-proximity quantification if a leak is detected).

Opgal OGI Compliance
With a validated sensitivity of 0.35 g/h, the EyeCGas Multi is nearly three times more sensitive than the strictest European regulatory standard required for aboveground or offshore facilities (1 g/h) and substantially supersedes the requirements for Type 1 screening and underground validation.
