EPA’s OOOOb and OOOOc: An Overview
The EPA’s final methane rule divides requirements into two main sections:
Subpart OOOOb: This applies to new, modified, or reconstructed oil and gas infrastructure from December 6th, 2022 onward. It mandates more frequent and rigorous monitoring of methane emissions.
Subpart OOOOc: This section provides guidelines for states to develop their own emissions reduction standards for infrastructure built before December 6th, 2022, through State Implementation Plans (SIPs).
The new rule also opens the door for operators to adopt advanced emissions monitoring technologies, such as those offered by Spectra33, for their leak detection and repair (LDAR) programs. This is the first time the EPA has approved the use of alternative technologies for compliance, marking a significant shift toward innovative solutions.
Advanced Technology Compliance: IRIS Fusion Hub
With the EPA’s permission to use advanced technologies for emissions monitoring, operators have unprecedented flexibility in how they achieve compliance. Spectra33’s IRIS Fusion Hub stands out by combining multiple sensors into one comprehensive solution that ensures precise detection across vast areas. The IRIS Fusion Hub integrates LiDAR, hyperspectral, and OGI sensors to detect methane emissions under a variety of conditions, making it a perfect fit for compliance with Subpart OOOOb.
1. Periodic Emissions Monitoring
The EPA’s rule allows for periodic site screening using advanced technologies with varying levels of sensitivity. The EPA Periodic Screening Matrix outlines detection thresholds based on the performance of the technology in use:
Less sensitive technologies (≥ 10 kg/hr detection sensitivity) must scan more frequently, supplemented by annual OGI surveys.
Higher sensitivity technologies (≤ 2 kg/hr) can scan less frequently, eliminating the need for OGI surveys altogether.
Spectra33’s IRIS Fusion Hub is designed to meet the highest performance standards, achieving detection sensitivities as low as 1 kg/hr. This means operators using our platform can reduce the frequency of site scans while maintaining compliance with the EPA’s strict methane detection thresholds.
2. Targeted Follow-Up for Confirmed Detections
The new rule specifies that only sites with confirmed detections need follow-up investigations by ground crews. Spectra33’s IRIS Fusion Hub excels in spatial resolution, pinpointing the exact location of emissions down to the equipment scale. This capability allows operators to perform targeted follow-ups, reducing the time and cost associated with full-site inspections.
Continuous Emissions Monitoring with Spectra33
In addition to periodic monitoring, the EPA’s rule includes provisions for fixed-sensor systems that continuously monitor methane emissions. If emissions exceed site-level “action thresholds,” operators must initiate remedial action within five days.
The IRIS Fusion Hub’s combination of sensors and AI-driven insights provides continuous monitoring with immediate alerts when emissions exceed these thresholds. Operators can rely on our platform to quickly identify and mitigate potential issues, ensuring compliance with minimal downtime.
Advanced Reporting, Dashboards, and Historical Data with Spectra33
Spectra33 goes beyond mere detection by offering robust reporting capabilities that simplify compliance efforts. The IRIS Fusion Hub is equipped with a real-time dashboard that provides detailed emissions data, including plume trajectories, emission rates, and geotagged locations of detected leaks. This enables operators to generate comprehensive reports for regulatory submissions effortlessly.
1. Customizable Dashboards
Operators have access to customizable dashboards that offer clear visibility into emissions across all monitored sites. The dashboard can be tailored to display the most relevant data, including real-time alerts, past scan results, and upcoming compliance deadlines. This user-friendly interface allows operators to track emissions performance and detect trends over time, ensuring proactive management of methane emissions.
2. Automated Reporting
The EPA requires operators to submit reports detailing their emissions monitoring activities. Spectra33’s IRIS platform automates this process by generating comprehensive, compliant reports that meet all EPA standards. Reports can include details on confirmed detections, emission source localization, and remedial actions taken, all of which are crucial for meeting EPA’s stringent requirements.
3. Historical Records for Audits
Spectra33’s IRIS Fusion Hub stores all emissions data in a centralized database, allowing operators to maintain historical records of emissions scans and follow-up actions. These records are invaluable during audits or regulatory reviews, offering a transparent and verifiable account of compliance efforts. By maintaining a thorough history of emissions data, operators can demonstrate continuous improvement and adherence to EPA regulations over time.
Super Emitter Program: Preparing for Compliance
The EPA’s new Super Emitter Program adds another layer of accountability. A super emitter is defined as any source emitting more than 100 kg/hr of methane. Under the program, third parties, such as environmental groups, may report super emitters to the EPA, which will then require operators to investigate and repair these emissions.
Spectra33’s IRIS Fusion Hub provides operators with the tools needed to validate or refute super emitter claims. With precise emissions quantification and real-time reporting, operators can quickly determine whether they are responsible for the reported emissions and take appropriate action.
Advanced Technology Approval Process
The EPA requires that any advanced technology used for methane monitoring must be approved before it can be used for compliance. Spectra33’s IRIS Fusion Hub is in the process of obtaining EPA approval, and we expect our technology to be one of the first to meet the required standards. Once approved, our platform will be listed on the EPA’s official website, allowing operators to confidently integrate our solutions into their compliance programs.
