Kinder Morgan poisoned our air with chemicals for years!

The Non-Financial Ledger

Argo, Illinois is a working-class suburb southwest of Chicago. The people who live near 8500 West 68th Street didn’t sign up to breathe industrial solvent vapors. They also didn’t agree to live downwind of tanks leaking isopropyl acetate, methyl isobutyl ketone, butyl acetate, and cyclo-hexanone into the air. They almost certainly didn’t know it was happening.

The chemicals documented leaking from Kinder Morgan’s tanks are not abstract regulatory categories. Methyl isobutyl ketone irritates the eyes, nose, throat, and lungs. Repeated or high-level exposure can cause headaches, dizziness, and damage to the central nervous system. Isopropyl acetate causes respiratory tract irritation. Butyl acetate produces narcotic effects at high concentrations and is a known irritant. Cyclo-hexanone has been associated with narcotic effects and potential kidney and liver toxicity. These are the materials that were escaping from vents, seams, and accumulator systems at readings that, in one instance, hit 12,600 ppm. That is not a trace amount. That is a sustained, concentrated release happening repeatedly across multiple tanks over multiple years.

The people who live, work, go to school, or spend time near this facility had no way to know this was occurring. There is no public alarm for a pressure accumulator that quietly exceeds safe thresholds for 48 hours at a stretch. There is no neighborhood warning when a tank’s emergency vent reading spikes to nearly 10,000 ppm. The system that was supposed to capture those vapors, burn them off safely, and keep them out of the surrounding air was failing repeatedly. And the company kept operating.

The $238,000 fine Kinder Morgan agreed to pay will not undo years of elevated chemical exposure for anyone in that neighborhood. It will not pay a single medical bill. It will not clean the air that was already breathed. It resolves the legal liability and nothing else.

Regulatory Gray Zones

The emissions control failures at Kinder Morgan’s Argo facility occurred within a web of interlocking regulatory requirements; the gray zone was not in what the rules said, but in the gap between what was written on paper and what anyone verified was actually happening.

• The Illinois State Implementation Plan (SIP) requires a construction permit before modifying any emissions source. Kinder Morgan held those permits. However, holding a permit does not mean the equipment is functioning to spec. The construction permit for the Dow Chemical Dedicated Service Facility (CP No. 92020053) required that the closed vent system operate with “no detectable emissions” as measured by 500 ppm or less using EPA Method 21. Readings reaching 12,600 ppm show that the gap between permit compliance on paper and operational reality can be enormous, with no continuous real-time monitoring enforcing the gap.
• The Bulk Gasoline Terminal NESHAP at 40 C.F.R. Part 63, Subpart BBBBBB, requires that pressure-vacuum vents in the vapor collection system not open at system pressures below 4,500 pascals (18.1 inches of water column). This rule is designed to prevent uncontrolled hydrocarbon releases during gasoline loading. The vent at Bay 2 was opening at 16 inches of water column. This was discovered not through the company’s own monitoring and disclosure but through an EPA inspection using an infrared camera. The regulation assumes functional equipment; it contains no mechanism compelling ongoing operator verification that vents are calibrated to the correct threshold.
• The NESHAP General Provisions at 40 C.F.R. § 63.6(e)(1)(i) require that the operator “operate and maintain any affected source…in a manner consistent with safety and good air pollution control practices for minimizing emissions.” This standard is operationally vague. It creates a compliance obligation but relies on the operator to self-police. Kinder Morgan’s accumulator system pressurized above its design threshold 21 times over three years. The regulation required good practices; the mechanism to ensure those practices were followed was an inspection that happened years into the pattern of failures.

How Capitalism Exploits Delay: Time as a Corporate Weapon

The timeline from first documented violation to final resolution spans seven years, a period during which operations continued and the air quality impacts documented in this case were ongoing.

• The gasoline loading rack violation at Bay 2, documented by EPA using an infrared camera showing a visible hydrocarbon plume, was observed during the July 30, 2019 inspection. The penalty for this and other violations was not finalized until May 27, 2026: nearly seven years later.
• The accumulator pressure failures occurred across a documented window of January 2020 through December 2022, three full years. These failures were not discovered by Kinder Morgan’s own reporting; they emerged from EPA information requests and document review. The company submitted pressure monitoring records to EPA in response to a July 2, 2024 Request for Information, and the company’s own records confirmed 21 overpressure events.
• EPA issued a Notice and Finding of Violation on March 27, 2023. Representatives of both parties conferred on April 24, 2023. The Consent Agreement and Final Order was not filed with the Regional Hearing Clerk until May 27, 2026, more than three years after the NOV/FOV was issued.
• Kinder Morgan completed the required corrective actions, including replacing pressure vacuum vents, repairing leaking equipment, and reconnecting Tank 10-30 to VCU-3, between May 5, 2020 and June 9, 2023. The company fixed the equipment before the penalty was finalized, a common pattern that demonstrates how penalties are not a precondition for compliance, and how compliance does not shorten the penalty resolution timeline.
