Stack testing — also called performance testing or source testing — is used to measure a facility's air emissions and verify compliance with emission limits established under the Clean Air Act (CAA). A stack test tends to go one of two ways: planned and predictable, or compressed and reactive. The difference comes down to coordination. Delays in scheduling or execution can quickly lead to retesting costs, missed compliance deadlines, production disruptions, and increased regulatory risk. What starts as a timing issue can escalate into a much larger operational and financial impact. This guide breaks down what stack testing is, when it is required, and how to execute it in a way that supports compliance and operations. What Is Stack Testing? Stack testing quantifies regulated air emissions at the source and is required to demonstrate compliance under federal programs, including NSPS, MACT, and NESHAP. It is used to demonstrate both initial and ongoing compliance under major federal programs, including New Source Performance Standards (NSPS) under 40 CFR Part 60, Acid Rain Program (Part 75, CEMS), National Emission Standards for Hazardous Air Pollutants (NESHAP) under 40 CFR Part 61, and Maximum Achievable Control Technology (MACT) standards under 40 CFR Part 63. When Is Stack Testing Required? Initial Compliance New or modified sources typically face specific regulatory deadlines for completing an initial stack test: NSPS (40 CFR Part 60): Within 180 days after initial startup, or 60 days after reaching maximum production rate MACT (40 CFR Part 63): Notice of Compliance Status is typically due within 150 days for certain subparts Ongoing Permit Requirements Facilities with an Air Pollution Control Permit are commonly required to conduct periodic testing to demonstrate continuous compliance. Regulatory agencies can also require a test at their discretion, particularly when no continuous monitoring system exists or when previous results showed a narrow compliance margin. Specific Operational Triggers Stack testing is also required in these situations: CEMS evaluations – Relative Accuracy Test Audits (RATA) and linearity checks to verify Continuous Emission Monitoring Systems Rule changes – Updates to federal standards (Residual Risk and Technology Reviews, revised PM thresholds) can trigger new testing mandates Information Collection Requests (ICRs) – EPA may require testing under CAA Section 114 to support new rulemaking Engineering and Investigative Testing Not all stack testing is regulation driven. Facilities routinely test for internal purposes — process optimization, control device evaluation, and emissions profiling for future planning. Core Requirements for a Valid Stack Test To produce defensible data, stack tests must meet strict regulatory criteria: Representative Conditions: testing must reflect normal or worst-case operations  Run Structure: compliance is based on the average of three consecutive valid runs   Advance Regulatory Notification: These windows exist to give the regulatory agency the opportunity to observe. 30 days (Part 60, Part 61)  60 days (Part 63)  Data Integrity: invalid runs must be reported and may require replacement  Failure to meet these requirements can result in rejected data or required retesting. How a Stack Test Works Most compliance tests follow the same general structure: Pre-test planning and method selection Site-specific test plan development and agency notification Equipment setup and calibration Three test runs per emission point, with QA/QC checks Final report preparation and submission A straightforward test typically takes one to two days per emission point. Complex programs — multiple pollutants, restricted access points, or extended run times — take longer. What Does a Stack Test Report Include? The final report is the primary compliance document. A well-structured report should include: Executive summary – What was tested, why, and how results compare to limits Test program summary – Facility details, regulatory drivers, emission sources, control systems, and site-specific plans Summary of results – Emissions data alongside operating conditions, compared directly to permit limits Methodology – EPA reference methods used and any method-specific considerations Appendices – Field data sheets, calibration records, process data, and example calculations Stack testing is as much about scheduling coordination as it is about testing execution. Facilities that align planning, operations, and testing early gain flexibility and reduce risk. Those that delay often face limited options and higher costs.

Facilities subject to NSPS Subpart OOOOb must monitor flare performance to demonstrate proper combustion and emissions control. One of the key parameters required under the rule is Net Heating Value (NHV) .  Understanding how NHV sampling works, which equipment is affected, and current compliance timelines is critical for oil and gas operators preparing for NSPS OOOOb. We asked our experts to answer the most common NHV sampling questions facilities ask, including practical considerations shaped by real fieldwork. Here’s what to know before you start building or adjusting your program. How Alliance Technical Group Supports OOOOb NHV Compliance  Preparing for NSPS OOOOb compliance requires coordination across sampling, laboratory analysis, and reporting. With the June 1, 2026 deadline approaching, any gaps in personnel, process, or data management can slow you down. Alliance Technical Group supports oil and gas operators through the full scope of NSPS OOOOb compliance. From applicability determinations and NHV sampling program development to laboratory analysis and data interpretation, our teams help facilities implement monitoring programs that meet current requirements and stay ahead of upcoming deadlines.

On April 4, 2026, the U.S. EPA finalized revisions to portions of the 2024 oil and natural gas regulations under the Clean Air Act, commonly referred to as OOOOb/c. These updates follow industry petitions, additional data submitted after the 2024 rule, and a formal reconsideration process initiated in 2025.   While the structure of the original rule remains in place, several key provisions have been adjusted to address implementation challenges, particularly around flaring and net heating value (NHV) monitoring.   Here is what changed and what it means for your compliance program.   What Changed in OOOOb/c   1. Temporary Flaring Extended to 72 Hours   The allowable duration for temporary flaring of associated gas has been extended from 24 hours to up to 72 hours for troubleshooting and repairs.   The rule also introduces a new "exigent circumstances" provision that grants additional time beyond 72 hours in cases where site access is limited due to:   Severe weather  Personnel shortages  Supply chain constraints  Operators must document and report these events.   2. Adjusted NHV Monitoring Requirements   Operators are no longer required to perform routine Net Heating Value (NHV) sampling for flares or enclosed combustion devices (ECDs)   unless conditions exist that could lower heating value , such as the presence of inert gases.   3. Associated Gas Exemption Removed   Additionally, the general exemption from NHV monitoring for associated gas at well sites has been removed. Going forward, associated gas sources will be subject to the same monitoring framework as other affected facilities.   4. Updated Parameters for Alternative Performance Tests   The revised rule also finalizes several updates to the alternative performance test option for both new and existing sources. Specific changes include:   NHV grab sampling can now be conducted upstream of the inlet to the control device.  The performance test window is set to 14 operating days, with weekend and holiday breaks allowed, provided sampling is spaced no more than 3-operating days apart from the previous sampling day.  Block hourly averaging is required for continuous samples.  A one-hour minimum sampling time applies to twice-daily samples, with an exception for sites where low or intermittent flow makes that duration infeasible.  5. Sampling Demonstration Clarification   The finalized rule also adds clarifying language confirming that the sampling demonstration can serve as an alternative to continuous monitoring for all air-assisted and steam-assisted flares and ECDs.   What Has Not Changed   It is important to note that the broader structure of OOOOb/c remains intact:   Performance standards for new, modified, and reconstructed sources still apply  States are still responsible for implementing emissions guidelines for existing sources  Documentation, reporting, and defensibility remain central to compliance  Current Compliance Deadlines   The EPA issued an Interim Final Rule on December 3, 2025, extending several OOOOb compliance deadlines. Those deadlines remain in effect.   What Oil & Gas Operators Should Do Next   Re-evaluate NHV compliance strategies:  Determine where sampling is still required and where it may no longer apply  Review flare and ECD operations:  Identify scenarios where inert gases or variable gas streams could still trigger monitoring  Update internal procedures and documentation:  Especially for flaring events exceeding 72 hours and exigent circumstances  Monitor upcoming rulemaking:  The EPA has indicated that additional revisions to the 2024 rule are still under development  Navigating OOOOb Requirements with Alliance   These revisions do not remove compliance obligations, but they do change how those obligations are met once they take effect. As the June 1, 2026, NHV compliance date approaches, many facilities are operating in a narrow window where the existing requirements remain in effect, even as the EPA has finalized changes that will soon alter monitoring and testing expectations.   Alliance Technical Group helps operators navigate this transition—clarifying what is required today, what will change once the amendments become effective, and how to implement a compliant, defensible approach that minimizes rework and enforcement risk while positioning facilities for the updated rule.   Read the official press release on the EPA Website.
