ABF FREIGHT SYSTEM

ABF Freight System, Inc., the less-than-truckload subsidiary of ArcBest Corp. (Nasdaq: ARCB), operates 96 EPA-regulated facilities across the United States [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. EPA ECHO data as of May 4, 2026 records 10 facility-quarters of noncompliance in the trailing 24 months and an estimated $11.77 million in penalty exposure over the same window, derived from a five-year penalty base apportioned pro rata [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. That dollar figure is anchored by a single event: on March 20, 2023, the U.S. Department of Justice filed a Clean Water Act consent decree against ABF in the U.S. District Court for the Western District of Arkansas, Case No. 2:23-cv-02039-PKH, requiring a $535,000 federal civil penalty plus injunctive relief covering stormwater compliance across ABF's national transportation network [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet] [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

Parent ArcBest's 2024 Impact Report, published April 22, 2025, centers its environmental narrative on equipment modernization, SmartWay recognition, and ABF City Route Optimization [source: https://s203.q4cdn.com/716791110/files/doc_downloads/2025/2024-Impact-Report.pdf]. EPA enforcement records covering the same reporting period describe a different operational picture: stormwater discharges from industrial activities at multiple ABF facilities without required National Pollutant Discharge Elimination System (NPDES) coverage, and permit-holding facilities with sampling, reporting, and recordkeeping deficiencies [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. The gap between those two accounts is the central analytical tension in this briefing. Against the single in-NAICS peer available for comparison, TFORCE Freight, ABF shows a lower raw violation count (10 vs. 77) but a penalty total within the same order of magnitude ($11.77M vs. $16.69M) on roughly 2.6 times the facility footprint [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

ABF Freight's federal environmental compliance profile over the past 24 months is dominated by a single, nationwide Clean Water Act settlement and a set of discrete facility-level incidents. On March 20, 2023, the U.S. Department of Justice, acting on behalf of EPA and joined by the Louisiana Department of Environmental Quality, the State of Maryland, and the State of Nevada, lodged a consent decree against ABF Freight System, Inc. in the Western District of Arkansas [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf]. EPA's settlement information sheet describes noncompliance that ABF itself identified through internal audits: facilities discharging stormwater associated with industrial activities to waters of the United States without a permit, and permitted facilities failing to meet sampling, reporting, and recordkeeping conditions [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. The decree required a $535,000 civil penalty and injunctive measures applicable to ABF facilities nationwide [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet].

The period from late 2023 through late 2025 is one of decree implementation rather than new federal CWA litigation. The most recent permit action across the 96-facility portfolio is dated December 18, 2024, per ECHO's exporter file [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. ECHO shows zero currently active major permits in its active_permits_count field for the corporate roll-up. That is a data artifact consistent with ABF's operations being principally regulated under general stormwater permits and state-level air permits rather than individual NPDES majors [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. A separate incident surfaced in trade press when EPA cited an ABF facility in Ohio following a diesel fuel release; environmental contractors recovered a fuel-and-water mixture, and EPA did not publicly disclose the mechanism of release [source: https://www.thetrucker.com/trucking-news/the-nation/abf-freight-cited-by-ohio-facility-leaks-diesel].

On the historical-liability side, EPA's Superfund site profile lists ABF FREIGHT SYSTEM INC under EPA ID ARD041430703 [source: https://cumulis.epa.gov/supercpad/CurSites/csitinfo.cfm?id=0600079]. That listing is distinct from the 2023 CWA matter. It reflects legacy site conditions rather than current operational violations. Aggregating the federal ECHO record, the consent decree docket, and trade-press reports, the 24-month enforcement picture for ABF comprises three elements: one nationwide CWA settlement driving the majority of the $11.77M apportioned penalty figure [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]; ongoing injunctive-relief obligations including stormwater structure maintenance protocols set out in the consent decree [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf]; and isolated spill-response events at individual service centers [source: https://www.thetrucker.com/trucking-news/the-nation/abf-freight-cited-by-ohio-facility-leaks-diesel]. No new federal Clean Air Act or RCRA consent decrees against ABF were identified in the research bundle for the 2024–2026 window.

Action 1 — United States, LDEQ, Maryland, and Nevada v. ABF Freight System, Inc., Case No. 2:23-cv-02039-PKH (W.D. Ark., filed March 20, 2023). Program: Clean Water Act, Sections 301 and 402 (NPDES stormwater). Outcome: Consent Decree lodged March 20, 2023; $535,000 federal civil penalty plus state-allocated payments to Louisiana, Maryland, and Nevada; nationwide injunctive relief requiring ABF to implement stormwater compliance measures, maintain stormwater structures, and designate responsible personnel for ongoing maintenance [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf] [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. EPA's information sheet frames the underlying conduct as self-identified noncompliance across multiple facilities, including unpermitted industrial stormwater discharges and permit-condition deficiencies in sampling, reporting, and recordkeeping [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. Secondary trade coverage confirmed the civil penalty amount and the multi-state scope [source: https://www.environmentenergyleader.com/stories/abf-freight-system-inc-to-pay-civil-penalties-for-clean-water-act-non-compliance,3841]. The 89-page decree is the single largest driver of ABF's ECHO penalty figure and sets the compliance baseline against which subsequent facility-level performance is measured.

Action 2 — EPA citation, Ohio facility diesel release (date not publicly specified in available record). Program: likely CWA and/or state spill-response authority. Outcome: EPA cited the facility; environmental contractors recovered a fuel-and-water mixture; contaminated tools and equipment were left in place to continue collecting residual fuel [source: https://www.thetrucker.com/trucking-news/the-nation/abf-freight-cited-by-ohio-facility-leaks-diesel]. EPA did not publicly disclose the root cause of the release per the cited reporting [source: https://www.thetrucker.com/trucking-news/the-nation/abf-freight-cited-by-ohio-facility-leaks-diesel].

Action 3 — Superfund historical listing. ABF FREIGHT SYSTEM INC is identified on EPA's Superfund Site Profile under EPA ID ARD041430703 [source: https://cumulis.epa.gov/supercpad/CurSites/csitinfo.cfm?id=0600079]. This is a historical and legacy listing and is not tied to the 2023 CWA matter.

Aggregate: ECHO's derivation methodology (viol_24mo=min(qtrs_with_nc,8); penalty_24mo=total_5yr*(24/60)) yields a 10-violation count and an $11.77M 24-month penalty figure for the 96-facility corporate roll-up [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The public docket supports the CWA consent decree as the principal driver; the remaining dollar figure reflects ECHO's pro-rata apportionment across the 60-month base and may include state-administered matters not itemized in federal press releases [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Facility-level EJ indices are reported as 0.0 in the ECHO aggregate for ABF's 96-facility portfolio, which is an aggregation artifact rather than an indication of zero exposure; ECHO's exporter file does not populate EJSCREEN indices for every freight-transport registration [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The research bundle does not provide per-facility EJ rankings, so the five facilities below are selected based on their prominence in the public enforcement record and corporate operational footprint.

ABF Freight — Fort Smith, Arkansas (corporate headquarters and principal service center). Fort Smith is ABF's operational anchor and the venue for the 2023 CWA consent decree filed in the Western District of Arkansas [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf]. The company has operated from Fort Smith since 1923, making it both the legal and historical center of the network [source: https://en.wikipedia.org/wiki/ABF_Freight_System] [source: https://grokipedia.com/page/ABF_Freight_System].

ABF Freight — Ohio facility (exact location not specified in the cited reporting). This site was the subject of an EPA citation following a diesel release; environmental contractors recovered a fuel-water mixture on site [source: https://www.thetrucker.com/trucking-news/the-nation/abf-freight-cited-by-ohio-facility-leaks-diesel].

ABF Freight — Louisiana facilities subject to LDEQ co-plaintiff jurisdiction in the 2023 consent decree. LDEQ joined the federal action and received allocated civil penalty payments addressed to the Fiscal Administrator, LDEQ, Office of Management and Finance, Baton Rouge [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

ABF Freight — Maryland facilities subject to State of Maryland co-plaintiff jurisdiction in the same consent decree [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

ABF Freight — Nevada facilities subject to State of Nevada co-plaintiff jurisdiction in the same consent decree [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf]. The four-jurisdiction structure of the decree — federal, Louisiana, Maryland, and Nevada — indicates that stormwater compliance deficiencies were identified across geographically dispersed service centers rather than concentrated at a single node [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet].

ECHO's top_pollutants field for the ABF roll-up is empty, which reflects the nature of LTL trucking facilities: they are not TRI-reporting manufacturers and typically do not generate Form R tonnage data [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The principal pollutant categories implicated by the public record are therefore defined by the 2023 CWA decree and the Ohio spill, not by TRI emissions inventories. Three categories stand out.

Industrial stormwater runoff. The 2023 consent decree addresses stormwater associated with industrial activities at truck terminals — typically containing suspended solids, oil and grease, total petroleum hydrocarbons, and trace metals from brake and tire wear [source: https://www.epa.gov/enforcement/abf-freight-inc-clean-water-act-settlement-information-sheet]. The exposure pathway is surface-water discharge to waters of the United States. EJ implications are concentrated in communities downstream of truck terminals, which in the LTL sector are frequently sited in industrial zones adjacent to residential areas [source: https://www.epa.gov/system/files/documents/2023-03/abf-cd.pdf].

Diesel fuel and petroleum hydrocarbons. The Ohio incident involved the release of diesel and the recovery of a fuel-and-water mixture [source: https://www.thetrucker.com/trucking-news/the-nation/abf-freight-cited-by-ohio-facility-leaks-diesel]. Primary exposure pathways are soil contamination, groundwater migration, and volatilization. Diesel-range organics include polycyclic aromatic hydrocarbons with documented human-health endpoints.

Mobile-source diesel exhaust (NOx, PM2.5). ArcBest's own 2024 Impact Report identifies equipment efficiency and SmartWay participation as its primary emissions-reduction levers, implicitly acknowledging that on-road diesel combustion is the company's dominant emissions category [source: https://s203.q4cdn.com/716791110/files/doc_downloads/2025/2024-Impact-Report.pdf]. Mobile-source emissions from LTL operations fall outside ECHO's stationary-source enforcement universe but are material to EJ analysis because service-center clusters concentrate truck traffic in specific census tracts.

Within NAICS 484122 (General Freight Trucking, Long-Distance, Less Than Truckload), the only in-bundle peer benchmark is TFORCE Freight, which ECHO records show with 77 facility-quarters of noncompliance and $16.69M in 24-month penalty exposure across 37 facilities, versus ABF's 10 violations and $11.77M across 96 facilities [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. On a per-facility basis ABF's violation density (0.10) is materially lower than TFORCE's (2.08), while ABF's per-facility penalty ($123K) is also well below TFORCE's ($451K) [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The comparison should be read with caution: ECHO's penalty derivation is a pro-rata estimate, and the two companies' facility counts reflect different operational reporting conventions [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

ABF Freight is a private subsidiary of ArcBest Corp. (CIK not provided in this bundle) and does not file its own 10-K. The research bundle does not include ArcBest's Item 1A text directly; trade coverage of ArcBest's 1Q26 earnings presentation indicates the company frames itself as 'a leading integrated logistics company' and discusses pricing and operating environment but does not, in the excerpted material, quantify forward environmental regulatory risk [source: https://www.marketscreener.com/news/arcbest-1q26-earnings-presentation-ce7f59d2d98bf72c]. The 2024 Impact Report's forward-looking statement section acknowledges energy, fuel, and regulatory exposure as material to operations [source: https://s203.q4cdn.com/716791110/files/doc_downloads/2025/2024-Impact-Report.pdf]. Two factors warrant monitoring: the ongoing injunctive-relief obligations under the 2023 consent decree, which impose continuing compliance costs, and the potential for state-level enforcement actions in Louisiana, Maryland, and Nevada, where co-plaintiff agencies retain independent authority. Readers requiring full Item 1A disclosure should consult ArcBest's most recent 10-K on SEC EDGAR directly.
