Approval Granted to New Emissions Monitoring Technology

New tools give operators methane management tools that are easy to implement.


LongPath Technologies has become 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 cost-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 cofounder 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.”

Operators can transition to LongPath’s system without additional applications— simply update your annual report to reflect the new monitoring method.

Significant cost savings can also be gained by eliminating the need for traditional AVO/OGI inspections, freeing resources for high-impact leak follow-up and repair.

LongPath’s low false-positive technology delivers precise, continuous data, helping operators reduce methane intensity and streamline operations.

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

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.
