TL;DR
- The EPA fined Rockies Express Pipeline, LLC $36,777 for a Clean Air Act violation at its Columbus Compressor Station in Ashville, Ohio.
- A compressor seal started leaking methane and volatile organic compounds on January 5, 2022. Federal rules gave the company two years to finish the repair.
- REXP missed that deadline. The company’s own annual report, filed March 27, 2024, admitted the leak was still active more than two years after it was first found.
- REXP did not confirm the leak was fixed until an October 23, 2024 meeting with EPA investigators, roughly nine months after the legal deadline had already passed.
- The company neither admitted nor denied wrongdoing, and its penalty is a fraction of the $124,426-per-day maximum the law allows.

Legal Receipts
Everything below is taken directly from the Consent Agreement and Final Order, Docket No. CAA-05-2026-0037. Nothing here is paraphrased.
“the company completed repairs to address leaks on the O-ring seal of its Solar C45 centrifugal compressor end cap and confirmed these repairs were successful.”
- This is REXP’s own account, given at an October 23, 2024 meeting, nearly three years after the leak was first detected.
- It confirms the leak was real, on a specific piece of equipment, and required a fix.
- It does not explain the multi-year gap between detection and the repair.
“REXP had detected a leaking valve on January 5, 2022, which had not been repaired as of the date of the report’s submittal.”
- This line comes from REXP’s own March 27, 2024 Annual Report, filed directly with EPA.
- It is a written company admission that the leak sat unrepaired more than two years after detection.
- The report was filed almost two months after the legal repair deadline had already passed.
“neither admits nor denies specific factual allegations contained in this CAFO”
- This is the legal language REXP used to settle the case.
- It means the company paid a penalty without formally admitting it broke the law.
- No court or agency ever forced REXP to acknowledge the violation in its own name.
“By failing to complete the repair of the compressor o-ring seal discovered to be leaking on January 5, 2022… REXP violated 40 C.F.R. § 60.5397a(h)(3)(i).”
- This is EPA’s own legal finding, citing the exact federal regulation REXP broke.
- It ties the violation directly to the compressor seal first flagged in January 2022.
- It is the closest thing to an official verdict this case produced.
How Capitalism Exploits Delay: Time as a Corporate Weapon
Federal law gave Rockies Express Pipeline a hard two-year ceiling to fix a known leak. The company’s own paperwork shows it blew through that ceiling and kept the station running anyway.
- January 5, 2022: REXP found a leaking O-ring seal on a Solar C45 compressor at its Ashville, Ohio station.
- January 5, 2024: The absolute legal deadline under 40 C.F.R. § 60.5397a(h)(3)(i) for completing the repair.
- March 27, 2024: REXP’s own Annual Report to EPA confirmed the leak was still unrepaired, nearly three months past deadline.
- April 18, 2024: An email exchange between EPA and REXP confirmed, again, that the component had still not been repaired.
- October 23, 2024: REXP told EPA investigators the repair was finally complete, more than two years and nine months after the leak was found.
Required by Law vs. What Actually Happened
Societal Impact Mapping
Environmental Degradation
Subpart OOOOa exists specifically to control the pollutants tied to this equipment. REXP’s compressor station kept leaking two of them past its legal deadline.
- The leaking O-ring seal qualifies as a “fugitive emissions component” under federal rules, specifically because of its potential to emit methane and volatile organic compounds.
- Subpart OOOOa exists to control methane, VOCs, and sulfur dioxide, the exact pollutant categories the Clean Air Act’s New Source Performance Standards program was built to address because they “significantly contribute to air pollution.”
- The 2-year outer limit for repairs exists precisely to cap how long a known leak can keep emitting. REXP’s leak ran past that cap.
The Settlement Isn’t Justice
REXP settled this case without admitting it broke the law, and the penalty EPA accepted is a fraction of what the statute allows.
- REXP “neither admits nor denies” the specific factual allegations in the CAFO. It paid to close the case without a legal finding of fault in its own words.
- The final penalty was $36,777, a figure EPA calculated using Clean Air Act Section 113(e) factors and, per the CAFO, credit for REXP’s cooperation.
- The Clean Air Act allows civil judicial penalties up to $124,426 per day per violation. Calculated from figures stated directly in the CAFO, the $36,777 assessed penalty here is less than one-third of a single day’s statutory maximum.
- Interest and late fees only begin accruing if REXP misses its 30-day payment window, meaning prompt payment lets the company close the matter for exactly $36,777 and nothing more.
Penalty Paid vs. Maximum Daily Penalty Allowed
This Is the System Working as Intended
This case shows exactly how the enforcement math favors the polluter.
- A leak that ran roughly two years and nine months past its legal deadline resulted in a penalty smaller than three days’ worth of the maximum statutory fine.
- REXP’s own annual report to EPA in March 2024 is what surfaced the delay. Self-reporting, not an inspection or a complaint, is what triggered the eventual Finding of Violation five months later.
- The CAFO settles only REXP’s liability for the violations “specifically alleged” in this one document. Nothing in the settlement requires REXP to prove no other fugitive leaks are running past deadline at this or any other station.
- REXP waived its right to a hearing, to appeal, and to a jury trial in the same document that let it avoid admitting fault.
What a Legitimate Fix Looks Like
Editorial analysisThis case exposes a system that relies on polluters to self-report their own violations and lets them settle without ever admitting fault.
Regulatory Track
- Require independent, third-party verification that a fugitive emissions repair is complete, instead of relying on the operator’s own confirmation given at a meeting with regulators.
- Shorten the outer repair ceiling for delay-eligible leaks below the current 2-year maximum, so violations like this one cannot legally run for years before triggering enforcement.
- As a general industry standard, publish Findings of Violation to a searchable public database the moment they are issued, not only after a settlement is finalized.
Legislative Track
- Amend the administrative settlement framework under the Clean Air Act so agreements like this one require a factual admission of the violation, not merely an admission of jurisdiction.
- Raise the floor on administrative penalties for fugitive emissions violations so a settlement cannot functionally cost less than the price of missing the legal deadline in the first place.
- Require pipeline operators to report fugitive emissions repair timelines to a public database in real time, closing the gap between detection and disclosure that let this leak run for over two years before EPA acted.
Corporate Governance Track
- Require the engineering leadership office that signed this CAFO to certify repair completion under independent audit, not internal confirmation alone.
- Tie compensation in the engineering and operations chain to documented, on-time closure of fugitive emissions repairs, not just detection and reporting.
- Establish an internal compliance unit with authority to escalate repairs nearing their legal deadline directly to executive leadership, independent of the business unit responsible for the equipment.
What Now?
Jay Meyers, Rockies Express Pipeline’s Senior Vice President of Engineering, is the executive who signed this settlement on the company’s behalf. The EPA already carries this case in REXP’s compliance history for any future enforcement action. Watch what happens next.
- EPA Region 5 Enforcement and Compliance Assurance Division, which now carries this case in REXP’s compliance history for any future enforcement action.
- Ohio EPA, which received a copy of the original Finding of Violation and holds jurisdiction over the Ashville facility.
- Track future NSPS Subpart OOOOa filings from Rockies Express Pipeline through EPA’s public docket system to see whether the two-year repair pattern repeats.
- Local Ohio residents and environmental groups can request compliance records for the Columbus Compressor Station directly from Ohio EPA under public records law.
- Anyone near the Ashville, Ohio compressor station can contact EPA Region 5’s Air Enforcement and Compliance Assurance Branch directly to report suspected ongoing leaks.
