EPA’s finalized revisions to NSPS Subpart KKKKa significantly change how new and modified stationary combustion turbines must demonstrate NOₓ compliance. If your facility constructed, modified, or reconstructed a turbine after December 13, 2024 , this rule likely applies. For electric utility power plants, independent power producers (IPPs), and industrial facilities with onsite generation, the update introduces: Stricter NOₓ emission limits New subcategorization based on utilization and efficiency Continuous compliance expectations (including startup and shutdown) Expanded reliance on CEMS and data validation This is a structural shift in how compliance is demonstrated.   When Does Subpart KKKKa Apply? Subpart KKKKa applies to stationary combustion turbines ≥10 MMBtu/hr that were constructed, modified, or reconstructed after December 13, 2024. The final rule became effective January 15, 2026. Turbines subject to KKKKa are no longer subject to Subparts GG or KKKK. Facilities should confirm: Construction commencement dates Whether recent changes qualify as “modification” or “reconstruction” Heat input rating Subcategory classification   What Changed: Key Technical Differences 2006 Subpart KKKK 2026 Subpart KKKKa >850 MMBtu/hr: 15 ppm @ 15% O₂ >850 MMBtu/hr (high utilization): 5 ppm @ 15% O₂ Size-based categories Utilization + efficiency criteria Traditional SSM interpretation Standards apply at all times Under Subpart KKKK (2006), large natural gas turbines (>850 MMBtu/hr) were typically limited to 15 ppm NOₓ @ 15% O₂. Under Subpart KKKKa (2026 revisions): High-utilization turbines (>45% capacity factor): 5 ppm @ 15% O₂ Low-utilization turbines with ≥38% design efficiency: 25 ppm @ 15% O₂ Low-utilization turbines with <38% efficiency: 9 ppm @ 15% O₂   The rule now integrates utilization rate and design efficiency directly into the regulatory structure. This means compliance is no longer based solely on turbine size and fuel type. Subpart KKKKa also clarifies that standards apply at all times , removing historical startup/shutdown exemptions and reinforcing continuous compliance expectations. A Large Operational Shift: Continuous Compliance for NSPS Subpart KKKKa The most significant practical change is EPA’s increased emphasis on continuous monitoring. Traditional Model New KKKKa Model Periodic stack test Continuous Emissions Monitoring Systems Quarterly / annual Rolling averages Snapshot compliance Continuous compliance Data validation & reporting For turbines using SCR or post-combustion controls, continuous emissions monitoring systems (CEMS) are required to demonstrate compliance with stringent limits such as 5 ppm NOₓ @ 15% O₂ on rolling averages. This shifts compliance from: Periodic stack testing → Continuous, data-driven performance demonstration Facilities must now ensure: Monitoring systems operate during all load conditions QA/QC procedures are robust and documented Data validation workflows are audit-ready Electronic reporting processes are accurate and timely   What Facilities Should Be Reviewing Now Facilities subject to Subpart KKKKa should treat this as a compliance program refresh. Key focus areas include: Applicability and affected unit inventory 12-month capacity factor calculations SCR performance capability and tuning CEMS configuration and certification Startup and shutdown monitoring procedures Recordkeeping structure and retention policies Reporting calendars and notification tracking Facilities planning future turbine installations should also evaluate how design efficiency and projected utilization will influence subcategory classification. How Alliance Technical Group Supports KKKKa Programs If you are assessing impacts or building a KKKKa compliance strategy, Alliance Technical Group can support your environmental team through: Applicability analysis and compliance matrix development Site-specific emissions testing and operating limit validation CEMS selection, installation support, and QA/QC programs Data validation and reporting system development Recordkeeping framework design and pre-submittal reviews Our regulatory specialists and emissions testing experts work alongside facility teams to build defensible, technically sound programs aligned with current NSPS requirements.

The United States Environmental Protection Agency finalized the repeal of specific amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units (EGUs), commonly referred to as the Mercury and Air Toxics Standards (MATS), that were promulgated on May 7, 2024.   The rule takes effect April 27, 2026, and restores specific compliance provisions that facilities have historically relied on under 40 CFR Part 63 Subpart UUUUU .  This article summarizes what changed, what didn’t, and what it means for coal and oil-fired electric generating units (EGUs) going forward.  What Did the EPA Repeal in 2026?  The EPA removed three major elements of the 2024 amendments, each of which would have tightened emissions or monitoring requirements. These repeals are documented in the rule and are listed below.   1. Stricter Filterable PM (fPM) Limit   Repealed: 0.010 lb/MMBtu for existing coal units  Restored: 0.030 lb/MMBtu (2012 standard)  Also reverses the associated tighter metal HAP limits.  2. Mandatory PM CEMS Requirement   Repealed: PM CEMS as the only compliance method  Restored: Flexibility to use:   Quarterly stack testing  PM CPMS  PM CEMS  3. Tightened Mercury Limit for Lignite Units   Repealed: 1.2 lb/TBtu  Restored: 4.0 lb/TBtu  What Was Not Repealed?  The EPA removed only three elements of the 2024 amendments. All other provisions of the 2012 MATS rule and the 2020 Residual Risk and Technology Review (RTR) remain fully enforceable. Key Requirements That Remain in Effect  All original 2012 emission limits (PM, metals, acid gases, Hg, SO₂ surrogate)  All 2012/2020 work practice standards  All performance testing requirements (Methods 5, 29, 26A, 320, 30B, etc.)  Continuous monitoring requirements (Hg CEMS, sorbent traps, HCl/HF CEMS, SO₂ CEMS, PM CPMS)  Electronic reporting through ECMPS  2020 residual risk findings  All Subpart UUUUU definitions, test methods, appendices, and rule text (except where directly tied to the repealed 2024 amendments)  As a result, facilities must continue to maintain existing monitoring systems, meet emissions limits, and comply with performance testing and reporting requirements under 40 CFR Part 63 Subpart UUUUU .    Additional Updates to Electronic Reporting  The EPA also clarified electronic reporting requirements under the MATS rule. These revisions do not alter the underlying reporting requirements but update references and file format specifications used for electronic submissions.   Removed references to “ECMPS” and replacing with “ECMPS Reporting Tool”  Revised the XML file format to “any file format specified by the Administrator”    What This Means for Power Plant Operators  The 2026 repeal simplifie s MATS compliance by returning to a familiar regulatory framework. Operators regain flexibility in monitoring methods, face less stringent fPM and Hg limits, and may benefit from reduced compliance costs.  At the same time, the core structure of MATS—emission limits, monitoring, reporting, and work practices—remains unchanged. Facilities must continue to meet all 2012 MATS and the 2020 Residual Risk and Technology Review (RTR) requirements.  How Alliance Technical Group Can Help  Alliance Technical Group supports power plants and industrial facilities with MATS compliance programs, including stack testing, monitoring strategy support, CEMS, QA/QC procedures, and ECMPS reporting .  If you are evaluating how the 2026 MATS repeal may impact your compliance approach, Alliance Technical Group can help review your current program and identify any adjustments needed to remain aligned with the rule.   Susan Butler-Kennedy, QAP Regulatory Manager, ACS/DAS Susan has 25+ years of experience in the power industry, helping power plants and related facilities comply with various environmental laws and regulations.

On February 12, 2026, the EPA finalized the rescission of the 2009 Endangerment Finding under Section 202(a) of the Clean Air Act (CAA), concluding that this Section does not provide statutory authority to regulate greenhouse gas (GHG) emissions from motor vehicles for climate purposes (“the February 2026 Rescission”). 1  This action follows a multi-agency review initiated in early 2025. The agency has further stated its intent to reconsider all regulations that rely on the Endangerment Finding, including those GHG provisions promulgated under Section 111 of the CAA. What Has Been Proposed and Changed for Industrial Sources   While the February 2026 Rescission directly addresses only mobile sources, it signals a broader shift in federal GHG regulatory policy.    The EPA has proposed or finalized several actions affecting industrial facilities:   On September 12, 2025, EPA proposed permanently removing GHG reporting obligations under 40 CFR Part 98 all source categories, except for Subpart W (reporting delayed until RY2034), including petroleum refineries, power plants, and most other industrial facilities. Rescinded the Waste Emissions Charge (WEC) that would have imposed fees on methane emissions from oil and gas facilities.    Initiated regulatory shift for stationary sources under Section 111, including pursuing to repeal all GHG emissions standards for the power sector. 2    Finalized on December 3, 2025, extended compliance deadlines for oil and natural gas facilities under NSPS OOOOb/c. 3    Timing and Legal Considerations   Any comprehensive repeal of GHG regulations for stationary sources would require successful defense of the February 2026 Rescission against inevitable litigation before it can pursue a similar challenge to the Section 111 authorities that underpin NSPS rules. With less than three years remaining in the current presidential term, some regulatory reconsiderations may extend beyond this administration.    The Bottom Line   While the rescission signals a shift in regulatory direction, final outcomes will depend on rulemaking completion and court decisions. Most stationary source requirements remain in place today. Facilities should avoid assuming immediate elimination of GHG-related obligations.      Alliance continues to monitor federal and state regulatory developments closely. If you have questions about how these proposed changes may affect your facility, our team can help assess your current obligations and planning considerations.      1   https://www.epa.gov/regulations-emissions-vehicles-and-engines/final-rule-rescission-greenhouse-gas-endangerment#rule-summary    2   https://www.federalregister.gov/documents/2025/06/17/2025-10991/repeal-of-greenhouse-gas-emissions-standards-for-fossil-fuel-fired-electric-generating-units     3   https://www.epa.gov/controlling-air-pollution-oil-and-natural-gas-operations/2025-interim-final-rule-extend-compliance
