ABF FREIGHT SYSTEMS, INC.

ABF Freight System, Inc., the less-than-truckload subsidiary of ArcBest Corporation (NASDAQ: ARCB), operates 169 facilities tracked by EPA ECHO, with a derived 24-month violation count of 12 and a derived penalty total of approximately $6.21 million based on the ECHO exporter methodology (viol_24mo=min(qtrs_with_nc,8); penalty_24mo=total_5yr*(24/60)) [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. That figure is anchored by one dominant enforcement event: a federal Clean Water Act consent decree filed March 20, 2023 in the U.S. District Court for the Western District of Arkansas, Case 2:23-cv-02039-PKH, co-prosecuted by the United States, Louisiana DEQ, Maryland, and Nevada [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

The decree resolved allegations tied to stormwater non-compliance at multiple ABF service centers. It required both civil penalties and injunctive relief, including mandatory upgrades to stormwater pollution prevention programs across covered terminals [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. Those obligations remain active. ArcBest's 2024 Impact Report and 2023 Sustainability Report describe ABF as an EPA SmartWay Leader and a 14-time Inbound Logistics G75 Green Supply Chain Partner, with disclosed focus areas of equipment efficiency, city-route optimization, and service-center energy use [source: https://arcb.com/investor-relations/environmental-sustainability] [source: https://s203.q4cdn.com/716791110/files/doc_downloads/2025/2024-Impact-Report.pdf]. The SmartWay and G75 credentials and the stormwater consent decree coexist as simultaneous facts about the same service-center network. Peer-set data from EPA ECHO shows TForce Freight, operating far fewer facilities — just 37 — in the same NAICS 484122 code, carrying a higher derived 24-month penalty total of $16.69 million [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

ABF Freight System's compliance profile over the past 24 months is shaped by a single large federal Clean Water Act resolution rather than a dispersed pattern of small-dollar state actions. EPA ECHO's exporter file lists 169 facility identifiers linked to the company, zero currently active permits in the ECHO feed, and a latest permit date of November 26, 2013 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The absence of active permits in the ECHO snapshot reflects a structural feature of the LTL sector: most terminals operate under general industrial stormwater permits administered at the state level, which do not appear as individually issued NPDES permits in the federal exporter. EJSCREEN index averages are reported as 0.0 in the underlying feed. That value signals a null or unpopulated field, not a substantive finding of zero environmental exposure.

The material event sequence begins February 17, 2023, when the consent decree was lodged, followed by the March 20, 2023 filing in the Western District of Arkansas naming ABF Freight System, Inc. as defendant and the United States, Louisiana Department of Environmental Quality, State of Maryland, and State of Nevada as plaintiffs [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf]. EPA's Clean Water Act settlement information sheet, published in March 2023, summarizes the scope of alleged stormwater discharges at ABF service centers and the injunctive relief package [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. Trade press coverage the same month reported the civil penalty payment and the non-compliance framing [source: https://www.environmentenergyleader.com/stories/abf-freight-system-inc-to-pay-civil-penalties-for-clean-water-act-non-compliance,3841].

Outside the federal docket, historical state actions include a November 2006 California Air Resources Board settlement of $6,500 regarding idling and diesel requirements [source: https://ww2.arb.ca.gov/abf-freight-system-inc-settlement], and a legacy Superfund listing under EPA ID ARD041430703 identified as the ABF Truck Line Warehouse site [source: https://cumulis.epa.gov/supercpad/CurSites/calinfo.cfm?id=0600079]. Both predate the 24-month window by years. In the last 30 days, company news flow has been dominated by operational and security items — ABF Freight's 12th American Trucking Associations Excellence in Security award and 2025 perimeter-detection rollouts — rather than environmental enforcement [source: https://www.stocktitan.net/news/ARCB/abf-freight-receives-ata-excellence-in-security-award-for-record-gd03le26w4ij.html]. No new EPA enforcement filings against ABF appear in the 30-day or 365-day news sweeps surveyed.

Primary action — United States et al. v. ABF Freight System, Inc., Civil No. 2:23-cv-02039-PKH, W.D. Ark.: The consent decree was lodged February 17, 2023 and formally filed March 20, 2023. The governing statute is the Clean Water Act, Sections 301 and 402, covering stormwater discharges associated with industrial activity at ABF service centers. Co-plaintiffs were the United States on behalf of EPA, the Louisiana Department of Environmental Quality, the State of Maryland, and the State of Nevada. Required relief included a civil penalty plus injunctive obligations: upgraded Stormwater Pollution Prevention Plans, employee training, facility inspections, and multi-year reporting at covered terminals [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf]. EPA's case summary page confirms the Clean Water Act basis and the multi-state plaintiff structure [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. Contemporary trade press described the resolution as civil penalties for Clean Water Act non-compliance [source: https://www.environmentenergyleader.com/stories/abf-freight-system-inc-to-pay-civil-penalties-for-clean-water-act-non-compliance,3841].

ECHO-derived aggregate: 12 violations over 24 months and approximately $6.21 million in penalties using ECHO's derivation formula, across the 169 facility IDs listed [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. A separate peer benchmark row captured for the entity slug 'abf-freight-system' shows 10 violations and $11.77 million penalty_total_24mo using the same methodology across 96 facilities. The variance between the two ECHO-derived totals reflects differences in entity-slug facility mapping within the exporter snapshot. That discrepancy is flagged here as a data uncertainty rather than two independent enforcement populations [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Historical actions outside the 24-month window: California Air Resources Board, November 2006, $6,500 settlement relating to diesel program compliance [source: https://ww2.arb.ca.gov/abf-freight-system-inc-settlement]. Legacy Superfund site: ABF Freight System Inc./ABF Truck Line Warehouse, EPA ID ARD041430703, listed in EPA's CERCLIS/SEMS database [source: https://cumulis.epa.gov/supercpad/CurSites/calinfo.cfm?id=0600079]. No additional new federal civil or administrative actions against ABF Freight Systems, Inc. appear in the Brave or Exa source bundle for the 24-month window beyond the 2023 consent decree.

Arkansas — Fort Smith/Harrison area service centers: The ABF Truck Line Warehouse Superfund profile (EPA ID ARD041430703) sits in Arkansas and remains on EPA's Superfund information system, tying the company to a legacy contamination footprint in its historical operational base [source: https://cumulis.epa.gov/supercpad/CurSites/calinfo.cfm?id=0600079]. The Western District of Arkansas was also the venue chosen for the 2023 consent decree, reflecting ABF's headquarters-region nexus [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

Louisiana service centers: Louisiana Department of Environmental Quality joined the United States as a co-plaintiff in the 2023 Clean Water Act consent decree. That joinder indicates ABF facilities in Louisiana were among those where state inspectors documented stormwater-related non-compliance contributing to the federal action [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

Maryland service centers: The State of Maryland was a co-plaintiff, placing one or more Maryland ABF terminals within the scope of the injunctive relief and Stormwater Pollution Prevention Plan upgrade requirements of the decree [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet].

Nevada service centers: The State of Nevada was the fourth plaintiff. Nevada terminals were folded into the stormwater compliance program required by the decree, extending its geographic reach to the Southwest [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

California terminals: ABF's California fleet operations were the subject of the 2006 CARB $6,500 diesel settlement. The CARB docket entry remains public and represents the most recent California-specific environmental enforcement record identified in the source bundle [source: https://ww2.arb.ca.gov/abf-freight-system-inc-settlement].

Stormwater-associated pollutants at LTL freight terminals: The 2023 consent decree addresses discharges associated with industrial activity at trucking service centers. Under EPA's Multi-Sector General Permit framework, those discharges typically include total suspended solids, oil and grease, and metals mobilized from fueling, maintenance, and vehicle parking areas [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. The exposure pathway is surface runoff reaching adjacent municipal separate storm sewer systems and downstream receiving waters. ECHO's exporter does not report a populated top_pollutants list for the ABF entity, so specific pollutant loadings are not quantified in the source bundle [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Diesel particulate matter and NOx: The historical CARB settlement concerned diesel idling and fleet requirements — pollutants with established links to respiratory and cardiovascular morbidity in communities near freight corridors [source: https://ww2.arb.ca.gov/abf-freight-system-inc-settlement]. ArcBest's own disclosures emphasize equipment efficiency, aerodynamics, and SmartWay participation as the primary mitigation approach for tailpipe emissions [source: https://arcb.com/investor-relations/environmental-sustainability]. Those voluntary programs address the same pollutant categories the 2006 CARB action flagged, though through a different regulatory mechanism.

Legacy Superfund contaminants: The ABF Truck Line Warehouse Superfund profile (EPA ID ARD041430703) is maintained in EPA's Superfund site information system. The site profile page is the authoritative EPA reference for contaminant listings at that location [source: https://cumulis.epa.gov/supercpad/CurSites/calinfo.cfm?id=0600079]. Environmental justice implications cannot be quantified from the source bundle because the ECHO ej_index_avg field is reported as 0.0, which the exporter documentation treats as unpopulated rather than as a scored result [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Within NAICS 484122 (General Freight Trucking, Long-Distance, Less Than Truckload), the ECHO exporter peer set shows TForce Freight carrying the highest derived 24-month penalty total at approximately $16.69 million across just 37 facilities and 77 violations — materially above the ABF Freight System peer row at $11.77 million across 96 facilities and 10 violations [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The ABF Freight Systems, Inc. entity file analyzed in this briefing shows 12 violations and $6.21 million across 169 facilities using the same derivation methodology [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. On a per-facility basis, ABF's derived penalty intensity sits well below TForce's and materially below the ABF peer-row aggregate. The two ABF-slug rows should be read as partially overlapping facility populations rather than independent operators, a data limitation that affects direct comparison.

ArcBest Corporation is the SEC registrant for ABF Freight System, Inc. The research bundle supplied for this briefing contains no populated SEC 10-K Item 1A risk factor excerpts or 10-Q environmental disclosures, so a direct forward-looking risk quotation cannot be reproduced here. The sustainability disclosures available describe environmental focus areas including greenhouse gas emissions, equipment efficiency, and service-center operations as ongoing management items [source: https://s203.q4cdn.com/716791110/files/doc_downloads/2025/2024-Impact-Report.pdf]. The 2023 federal consent decree imposes multi-year injunctive obligations — upgraded Stormwater Pollution Prevention Plans, inspections, training, and reporting — that constitute a continuing compliance execution risk through the decree's full term [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].
