Shell Pumped Industrial Waste Underground Near Your Drinking Water β For Years, Nobody Noticed
The Non-Financial Ledger: What a Fine Cannot Measure
Michigan City, Indiana sits on the southern shore of Lake Michigan. It is a working-class city with a median household income significantly below the national average. The people who live there are not lobbyists. They are not shareholders. They drink the water that comes out of their taps and trust, without knowing why, that someone is making sure it is safe.
That trust is the thing this story is about. Not the fine. Not the docket number. Not the regulatory acronyms. The trust.
Somewhere beneath the industrial complex at 1800 E US Highway 12, three injection wells push nonhazardous industrial wastewater deep into the earth. The law places a hard boundary on how close that fluid can get to drinking water formations, and a rigid schedule of mechanical tests to prove the wells are holding their integrity. The schedule exists because if a well casing fails, if a seal cracks, if fluid migrates upward along a borehole, there is no alarm that sounds in your kitchen. There is no text message. The contamination moves silently through rock and sediment and into the aquifer, and you will drink it before anyone confirms what happened.
For 125 days in the spring and summer of 2023, Well No. 3 at Shell’s Michigan City facility was injecting wastewater underground without a current, passing mechanical integrity test. The test that was supposed to confirm the well was sound had expired on April 6, 2023. Shell kept injecting. Nobody flagged it. Nobody pulled the plug. The well ran for four months beyond its compliance deadline, and the communities around it had no way of knowing.
That is not negligence in an abstract, corporate-liability sense. That is a company deciding, through inaction or inattention, that the administrative cost of managing its compliance calendar was someone else’s problem. The someone else, in this case, is every household and every school and every hospital that draws from groundwater connected to the aquifer system underneath LaPorte County.
The data falsification piece cuts even deeper. For over two years, Shell’s monthly operating reports to the EPA carried injection pressure readings that did not represent what was happening at the wells. The company later told regulators those numbers came from training simulations. Training simulations mixed, without any label or flag, into the official regulatory record. Every one of those reports was signed with a federal certification swearing the data was accurate. Every signature on every one of those reports carried the weight of a legal oath. The person who signed knew β or was legally required to know β that the information was being submitted to a federal agency to protect public health.
The fine that settled this case was $6,710. That number is not a punishment. It is an accounting entry. For a company whose parent posted nearly $40 billion in profit in a single year, $6,710 is the price of an afternoon. It does not cover the four months of unverified injection. It does not address the two years of muddied records. It does not compensate the people of Michigan City for the uncertainty they were never told they were living inside.
The people who live nearest industrial injection sites are, across the United States, disproportionately lower-income and disproportionately communities of color. They do not get to read the fine print of consent agreements. They do not attend the teleconferences between EPA attorneys and corporate lawyers. They find out, if they ever find out at all, from a paragraph in a local paper or an article on a website they stumbled across. They are the reason the Safe Drinking Water Act was written. They are the people the law was designed to protect.
Six thousand, seven hundred and ten dollars says how much that protection costs in 2024.
Legal Receipts: What the Documents Actually Say
These are not paraphrases. These are the verbatim words from the EPA Consent Agreement and Final Order, Docket No. SDWA-05-2024-0004, signed and filed September 26, 2024.
“I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.”
- This certification was legally required on every monthly operating report Shell submitted under its injection well permits. Shell’s representatives signed this statement across multiple report periods spanning June 2021 through June 2023.
- The EPA’s own review of those same reports found four instances where reported injection pressure values did not reflect real-world well conditions, because they came from simulated training exercises that were never flagged or separated from actual operational data.
- The document does not say Shell’s signatories knew the data was false. It says they certified it was accurate. Those are legally distinct positions, but they carry the same practical result: regulators received two-plus years of records they could not fully trust.
“The last Part II MIT for Well 3 (Permit IN-091-1I-006) was completed on April 6, 2018. The most recent Part II MIT was due to be completed by April 6, 2023. Well 3 was in operation without an up to date and passing Part II MIT from April 6, 2023, to August 9, 2023. Upon realizing the well was past due for testing, Respondent shut off the well and reported the issue to EPA on August 9, 2023. Respondent completed and passed a Part II MIT on Well 3 on August 15, 2023.”
- This paragraph establishes a 125-day window during which Well No. 3 was injecting industrial wastewater underground with no current verified proof that the well casing was not leaking fluid toward drinking water formations.
- The phrase “upon realizing the well was past due” is the crux. Shell did not have a system that triggered a compliance alert before the deadline. The company only caught the lapse after it had already occurred and the well had already been operating out of compliance for an undisclosed stretch of time.
- The well passed its test when it was eventually run on August 15, 2023. That result does not retroactively guarantee well integrity during the 125-day gap; it only confirms the well was sound at the moment of testing.
“On September 11, 2023, Respondent stated that all four apparent MIP exceedances did not represent real world conditions at the wells and were caused by simulated training exercises. The monthly reports for those dates did not distinguish between actual and simulated MIP values.”
- Shell’s position is that the pressure readings that exceeded permitted limits β including two that would have triggered automatic well shut-offs under the permit terms β were artifacts of training exercises, not actual emergencies.
- The critical admission is in the final sentence: the reports submitted to the EPA did not distinguish between simulated and real values. There was no notation, no flag, no separate column. A regulator reviewing those reports would have had no way to know they were looking at drill data, not real conditions.
- Two of the four exceedances were at levels that should have triggered automatic well shutdowns. If those readings were real, Wells 1 and 3 should have been taken offline immediately. If they were not real, the certification attached to those reports was inaccurate. Either scenario is a compliance failure.
“This CAFO constitutes a ‘previous violation’ as that term is used in EPA’s UIC Penalty Policy and to determine Respondent’s ‘history of such violations’ under Section 1423(c)(4)(B) of the SDWA, 42 U.S.C. Β§ 300h-2(c)(4)(B).”
- This clause permanently adds this enforcement action to Shell’s regulatory history. Under the EPA’s penalty calculation methodology, a prior violation record is one of the factors that escalates the penalty amount for any future violation.
- The practical effect is that Shell now carries a documented compliance failure on its UIC record. Any future inspection finding at any Shell injection well will be evaluated in the context of this prior action.
Societal Impact Mapping: Who Actually Bears the Risk
Public Health
The Safe Drinking Water Act’s underground injection control program exists for one reason: industrial fluids injected underground can and do migrate into drinking water sources if the infrastructure fails or monitoring lapses. Shell’s violations created two distinct gaps in that protective barrier.
- A Part II Mechanical Integrity Test is the primary federal tool for verifying that a well’s casing has not developed cracks, corrosion, or breaches that could allow injected fluids to migrate upward toward underground drinking water sources. Without a current, passing test on record, there is no documented evidence of well integrity. Well No. 3 operated in that undocumented state for 125 continuous days.
- The law defines “endangerment” under the SDWA as any injection that “may result in the presence in underground water which supplies or can reasonably be expected to supply any public water system of any contaminant.” The standard is “may” β not “did” and not “probably will.” The 125-day gap met that threshold by definition.
- The four instances of inaccurate injection pressure data in Shell’s monthly reports degraded the quality of the regulatory record used by EPA to assess whether wells are operating safely within their permitted parameters. Two of those readings, at pressure levels that should have triggered automatic well shutdowns, appeared in the official record as genuine exceedances. If a regulator had acted on that data as real, unnecessary responses could have occurred. If they dismissed it, they had no documented basis for doing so.
- LaPorte County, where Shell’s facility sits, draws on groundwater systems that are hydraulically connected across the region. Contamination events at industrial injection sites in comparable geological settings have taken years to surface and years more to remediate. The affected populations have no advance warning system.
- Michigan City has a poverty rate above the Indiana state average. Communities with fewer economic resources have less capacity to source alternative drinking water, pursue legal remedies, or relocate when contamination is confirmed. The people most at risk from inadequate monitoring are the people least equipped to respond to its consequences.
Economic Inequality
The penalty structure that resolved this case exposes a systemic imbalance in how environmental enforcement costs are distributed between corporations and communities.
- Shell paid $6,710 to settle violations that covered 125 days of unverified injection and over two years of inaccurate regulatory reporting. The maximum administrative penalty available under the SDWA for violations of this type is $348,671. Shell paid roughly 1.9% of the statutory maximum.
- Shell plc, Shell Catalysts & Technologies LP’s parent company, reported $39.9 billion in adjusted earnings for 2023. The $6,710 penalty represents approximately 0.000017% of that single year of earnings. Expressed differently, Shell earns the equivalent of this fine in approximately 88 seconds of continuous operation at 2023 earnings rates.
- The compliance fix Shell is required to implement under this order, a standard operating procedure for monitoring and reporting, is something a regulated entity operating in good faith should already have had in place before the violations occurred. The absence of such a procedure for a facility with three active injection wells adjacent to drinking water sources is itself a resource-allocation decision by management.
- The CAFO explicitly notes the penalty “is not deductible for federal tax purposes,” which signals that lawmakers anticipated corporations might attempt to reduce the effective cost of environmental fines by writing them off as a business expense. The prohibition reveals how low penalties can get absorbed into routine cost structures.
- Working-class residents near industrial facilities bear the health risk and the economic cost of potential contamination, including reduced property values, medical costs, and the burden of proving harm, while the corporations generating that risk settle enforcement actions for amounts that constitute rounding errors in quarterly earnings statements.
The “Cost of a Life” Metric
How the System Was Supposed to Work β And What Actually Happened
The federal UIC permit system has a specific architecture of required tests, reporting obligations, and certification requirements. Here is where Shell’s conduct diverged from that architecture.
What Now? Who to Watch, Who to Contact, What to Do
Shell Catalysts & Technologies LP is legally bound by the CAFO and now carries a documented prior violation on its federal UIC record. These are the people and institutions with the power to enforce, escalate, or resist what comes next.
Decision-Makers Named in This Document
- Michael D. Harris, Director, Enforcement and Compliance Assurance Division, EPA Region 5 β Harris signed the CAFO on behalf of the EPA on July 11, 2024. His division is responsible for monitoring Shell’s ongoing compliance with the new SOP requirements.
- Ann Coyle, Regional Judicial Officer, EPA Region 5 β Coyle signed the Final Order on August 26, 2024, making it legally binding. She has authority over the administrative resolution of this proceeding.
- Kenny Limmer (Shell Catalysts & Technologies LP Representative) β Limmer signed the Consent Agreement on June 20, 2024, on behalf of Shell, binding the company to its terms.
- Aselda Thompson (Shell Contact on Record) β Listed as Shell’s designated contact for service of the CAFO at Aselda.Thompson@shell.com. This is the company’s official point of contact for this enforcement action.
Regulatory Watchlist
- U.S. EPA Region 5 (Enforcement and Compliance Assurance Division) β Primary regulator of Shell’s UIC Class I program in Indiana. Responsible for reviewing Shell’s new SOP within 90 days of the CAFO’s effective date and for all ongoing injection well oversight at 1800 E US Highway 12, Michigan City, Indiana. Contact: R5WECA@epa.gov.
- U.S. EPA Underground Injection Control Program (National) β The federal program that administers all Class I injection well permits in states where EPA holds primacy, including Indiana. Publicly searchable permit databases track UIC compliance history by facility.
- U.S. Department of Justice (Environment and Natural Resources Division) β DOJ has authority under the SDWA to pursue criminal sanctions and civil collection actions if Shell fails to pay or violates the CAFO’s compliance terms. The CAFO explicitly preserves this authority.
- Indiana Department of Environmental Management (IDEM) β Indiana’s state environmental agency. While EPA holds primacy for Class I UIC wells in Indiana, IDEM oversees other environmental permit obligations at Shell’s Michigan City facility and receives reporting under state law.
- LaPorte County Health Department (Michigan City, Indiana) β The local public health authority for the community immediately adjacent to Shell’s facility. Local health departments have standing to request information on groundwater monitoring and environmental permit status.
Mutual Aid, Local Organizing, and Grassroots Resistance
- File a public records request. The CAFO is now a public document. Submit a Freedom of Information Act (FOIA) request to EPA Region 5 for Shell’s full monthly operating report history from June 2021 through the present, the inspection report from August 28, 2023, and all correspondence related to Docket No. SDWA-05-2024-0004. FOIA requests to EPA can be submitted online at foia.epa.gov.
- Comment on future enforcement actions. The SDWA requires public notice and a comment period before any consent order becomes final. If Shell violates this CAFO or faces new enforcement, that comment window is a direct line for community members to have their voices entered into the federal record. Sign up for EPA Region 5 enforcement notices.
- Connect with Michigan City and LaPorte County environmental justice organizations. Local environmental groups, tenant organizations, and community health coalitions in northwest Indiana are the frontline of any accountability effort. Connecting with them amplifies pressure on both the company and the regulators who oversee it.
- Push for stronger penalties at the legislative level. The $27,894 per-day statutory maximum for SDWA violations has not kept pace with industrial earnings. Contacting your U.S. Representative and Senator to advocate for updating the SDWA penalty structure to reflect modern corporate scale is a direct action with tangible policy consequence.
- Monitor Shell’s compliance with the new SOP requirement. Under the CAFO, Shell must submit a standard operating procedure to EPA within 90 days of the order’s effective date (effective 30 days after August 26, 2024 issuance). That SOP is a public document once filed. Community members can request it and hold Shell accountable to its own stated procedures.
- Support legal organizations that litigate environmental enforcement gaps. Earthjustice, the Environmental Defense Fund, and the Natural Resources Defense Council all have active programs challenging inadequate federal enforcement of drinking water law. Donations, volunteering, and signal-boosting directly support the legal infrastructure that holds companies like Shell accountable when regulators cannot or will not.
