LongPath Technologies has achieved a groundbreaking milestone, becoming the first continuous monitoring technology to receive U.S. Environmental Protection Agency (EPA) approval for fully replacing Audio-Visual-Olfactory (AVO) and Optical Gas Imaging (OGI) inspections under OOOOa, OOOOb, and pending OOOOc methane regulations. This approval covers all tiers (1–15 kg/hr) of periodic screening, setting a new standard for c

ost-effective, 24/7 emissions monitoring in the oil and gas industry.

"With this EPA approval, we're ushering in a new era of methane management," said Dr. Caroline Alden, Chief Scientist and Co-Founder of LongPath Technologies. "This is about more than meeting regulations—it's about giving operators the tools to transform methane data into a strategic advantage."

Why This Matters to Operators:

• Immediate Compliance: Operators can transition to LongPath's system without additional applications—simply update your annual report to reflect the new monitoring method.
• Significant Cost Savings: Eliminate the need for traditional AVO/OGI inspections, freeing resources for high-impact leak follow-up and repair.
• Actionable Insights: LongPath's low false-positive technology delivers precise, continuous data, helping operators reduce methane intensity and streamline operations.
• Tailored Solutions: From well pads to production facilities and compressor stations, LongPath offers scalable configurations that meet federal and state-level requirements (including those of New Mexico and Colorado).

A Turnkey Solution for Today's Challenges

Effective immediately, LongPath's advanced laser-based system gives operators the power to manage emissions by exception—detecting leaks faster, reducing gas loss, and reinforcing site safety. Its networked tower nodes can support multiple operators in the same region, offering a shared, cost-effective approach to emissions management.

As the push for emissions accountability grows, LongPath is charting a path toward ultra-low carbon natural gas and more efficient energy production. By simplifying compliance, lowering costs, and providing high-fidelity data, LongPath is setting a new benchmark for operational excellence and sustainability.
