DOW - SABINE RIVER OPERATIONS

Dow Sabine River Operations, a plastics and resin manufacturing complex (NAICS 325211) in Orange, Texas, has accumulated eight quarters of non-compliance and an estimated $3.89 million in apportioned penalties over the trailing 24 months, according to EPA ECHO exporter data as of May 4, 2026 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The site carries EPA facility registry ID 110017746368. It has operated under a federal Clean Air Act consent decree since January 2021 — filed as Case 2:21-cv-00114 in the Eastern District of Louisiana — that resolved claims brought by EPA, DOJ, and the Louisiana Department of Environmental Quality against The Dow Chemical Company, Performance Materials NA Inc., and Union Carbide Corporation across four petrochemical plants, Orange among them [source: https://www.epa.gov/enforcement/dow-chemical-company-performance-materials-na-inc-and-union-carbide-corporation-clean].

The decree's fenceline monitoring obligation has produced some striking numbers. Benzene readings at monitor SAB_AMP-05, published by Dow in May 2025 under Civil Action No. 2:21-cv-114, hit 99.1 µg/m³ on June 6, 2024 and 72.3 µg/m³ on May 23, 2024. Adjacent monitors on those same dates read an order of magnitude lower [source: https://corporate.dow.com/content/dam/corp/documents/ehs/orange/reporting-data-orange-050825.pdf]. That concentration gap points to a localized source near SAB_AMP-05 rather than diffuse complex-wide emissions. Separately, a Texas Attorney General action filed in February 2026 against Dow, Union Carbide, and Braskem at the Seadrift complex — a distinct facility on the central Gulf Coast, not Orange — alleges hundreds of Clean Water Act permit exceedances and describes the defendants as being in "habitual non-compliance" with state water permits [source: https://www.insurancejournal.com/news/southcentral/2026/02/19/858741.htm]. That filing is legally separate from the Orange site, yet it names the same corporate defendants and adds texture to the enforcement-risk picture across Dow's Gulf Coast asset base.

The Sabine River Operations site in Orange, Texas entered the current regulatory period already inside an enforcement envelope rather than from a clean permit baseline. On January 27, 2021, EPA, DOJ, and the Louisiana Department of Environmental Quality announced a settlement with Dow Chemical Company, Performance Materials NA Inc., and Union Carbide Corporation covering four Gulf Coast petrochemical plants, including Orange. EPA's release describes injunctive relief designed to eliminate "thousands of tons of air pollution," along with pollutant-specific controls on flares and process vents and enhanced leak detection and repair requirements [source: https://www.epa.gov/enforcement/dow-chemical-company-performance-materials-na-inc-and-union-carbide-corporation-clean]. The consent decree was filed in the Eastern District of Louisiana as Case 2:21-cv-00114 [source: https://www.epa.gov/sites/default/files/2021-01/documents/thedowchemicalcompany.pdf].

Since that 2021 resolution, the compliance record at Orange has been shaped primarily by decree-driven reporting obligations rather than fresh standalone federal cases. Dow's fenceline monitoring program — itself a consent-decree requirement — published ambient air data from 18 sample points (SAB_AMP-01 through SAB_AMP-18) with biweekly retrievals beginning in May 2024 and continuing through the May 8, 2025 dataset posting [source: https://corporate.dow.com/content/dam/corp/documents/ehs/orange/reporting-data-orange-050825.pdf]. Monitor SAB_AMP-05 returned readings well above its neighbors across four consecutive biweekly pulls: 72.3 µg/m³ on May 23, 2024; 99.1 µg/m³ on June 6, 2024; 9.5 µg/m³ on June 20, 2024; and 22.7 µg/m³ on July 3, 2024. That sequence is consistent with a localized source term near that single monitor rather than complex-wide fugitive emissions [source: https://corporate.dow.com/content/dam/corp/documents/ehs/orange/reporting-data-orange-050825.pdf]. EPA's ECHO exporter flags the facility with non-compliance in all eight of the trailing eight quarters and attributes roughly $3.89 million in apportioned penalty exposure to the 24-month window, a figure derived by scaling five-year penalty totals to a two-year interval [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

The past 24 months have also brought expanding regulatory attention to Dow's other Texas operations. In February 2026, the Texas Attorney General filed a 46-page complaint against Dow, Union Carbide, and Braskem tied to the Seadrift complex, following a December 2025 citizen 60-day notice-of-intent-to-sue under the Clean Water Act [source: https://www.insurancejournal.com/news/southcentral/2026/02/19/858741.htm]. Seadrift is legally distinct from Sabine River Operations. The filings nonetheless reference shared corporate defendants and a "habitual non-compliance" posture with TCEQ water permits, which is relevant context for analysts modeling enforcement-risk exposure across Dow's Texas asset base [source: https://www.insurancejournal.com/news/southcentral/2026/02/19/858741.htm]. One additional data point warrants mention: EPA ECHO reports zero active permits in the exporter snapshot and a latest permit action date of April 30, 2025. That combination typically reflects renewal timing or exporter population lag rather than any cessation of regulated activity, given that the facility continued publishing consent-decree-required fenceline monitoring data through May 2025 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Federal consent decree (January 27, 2021, Case 2:21-cv-00114, E.D. La.): EPA, DOJ, and LDEQ resolved Clean Air Act claims against The Dow Chemical Company, Performance Materials NA Inc., and Union Carbide Corporation covering four petrochemical plants, including the Sabine River Operations site in Orange, Texas. The decree requires flare efficiency improvements, waste gas minimization, and expanded leak detection and repair across covered process units, along with a civil penalty split between the United States and Louisiana [source: https://www.epa.gov/enforcement/dow-chemical-company-performance-materials-na-inc-and-union-carbide-corporation-clean]. The filed consent decree memorializes pollutant-specific injunctive relief covering volatile organic compounds, hazardous air pollutants, and flaring emissions [source: https://www.epa.gov/sites/default/files/2021-01/documents/thedowchemicalcompany.pdf].

Ongoing decree compliance reporting: Under the 2021 decree, Dow is required to publish fenceline benzene monitoring results at the Orange site. The May 8, 2025 dataset posted at corporate.dow.com covers 18 monitors around the Orange fenceline with biweekly retrievals from May 23, 2024 forward. It shows a persistent concentration spike at SAB_AMP-05 across multiple consecutive sampling periods [source: https://corporate.dow.com/content/dam/corp/documents/ehs/orange/reporting-data-orange-050825.pdf]. The readings at that single monitor — 72.3, 99.1, 9.5, and 22.7 µg/m³ across four biweekly pulls — stand in sharp contrast to the sub-10 µg/m³ readings at surrounding monitors during the same periods.

ECHO aggregate enforcement (24-month window ending May 4, 2026): EPA ECHO exporter records eight quarters of non-compliance at facility ID 110017746368 and an apportioned penalty total of $3,886,600.80, derived by scaling the five-year penalty sum to a 24-month interval [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. ECHO does not enumerate discrete new judicial actions against the Orange site within that window beyond decree-linked reporting.

Related non-Orange action for context: On or about February 13, 2026, the Texas Attorney General filed suit against Dow Chemical Co., Union Carbide, and Braskem at the Seadrift, Texas complex, alleging hundreds of water-pollution permit exceedances. The filing followed a December 2025 citizen 60-day notice [source: https://www.insurancejournal.com/news/southcentral/2026/02/19/858741.htm]. Historical reference: a prior "DuPont Sabine Settlement" exists in EPA's enforcement archive and pertains to a separate DuPont operation, not the Dow site [source: https://www.epa.gov/enforcement/dupont-sabine-settlement].

Dow Sabine River Operations (Orange, Orange County, TX — EPA FRS ID 110017746368): the sole facility in this briefing. EPA ECHO reports eight quarters of non-compliance over the trailing 24 months and $3.89 million in apportioned penalty exposure derived from five-year totals [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The site is one of four plants governed by the January 2021 Dow/Performance Materials NA/Union Carbide Clean Air Act consent decree in Case 2:21-cv-00114 (E.D. La.) [source: https://www.epa.gov/enforcement/dow-chemical-company-performance-materials-na-inc-and-union-carbide-corporation-clean]. Dow's May 2025 fenceline dataset tells a specific story about one monitor location. On June 6, 2024, SAB_AMP-05 recorded benzene at 99.1 µg/m³. Neighboring monitors on that same date read between 0.5 and 7 µg/m³. That concentration gradient — roughly an order of magnitude across a short fenceline span — indicates a localized emission source near SAB_AMP-05 rather than a uniform perimeter release [source: https://corporate.dow.com/content/dam/corp/documents/ehs/orange/reporting-data-orange-050825.pdf]. The ECHO record lists the EJ index average as 0.0 and top_pollutants as empty, which reflects exporter field gaps rather than a zero-exposure environment. The site sits adjacent to the Sabine River, a waterway with both active industrial discharge and recreational use [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip] [source: https://kogt.com/dsra-races-on-the-sabine-river/].

Benzene is the central fenceline analyte reported at the Orange site under the 2021 consent decree. EPA classifies benzene as a known human carcinogen with hematologic effects at chronic low-dose exposures. The agency's action level for refinery fenceline benzene under 40 CFR Part 63 Subpart CC is 9 µg/m³ as an annual average. The SAB_AMP-05 monitor readings of 72.3 µg/m³ on May 23, 2024; 99.1 µg/m³ on June 6, 2024; 9.5 µg/m³ on June 20, 2024; and 22.7 µg/m³ on July 3, 2024 each exceed that refinery benchmark on a spot-sample basis. The decree's compliance metric is a rolling average rather than individual spot values, which is a material distinction for interpreting those readings [source: https://corporate.dow.com/content/dam/corp/documents/ehs/orange/reporting-data-orange-050825.pdf].

Volatile organic compounds and hazardous air pollutants form the second pollutant family addressed by the 2021 consent decree. The decree targets flare efficiency, waste-gas recovery, and leak detection and repair across covered process units at all four plants in the settlement footprint [source: https://www.epa.gov/enforcement/dow-chemical-company-performance-materials-na-inc-and-union-carbide-corporation-clean]. Exposure pathways include fenceline inhalation and downwind residential zones. Intermittent flaring events can produce short-duration, high-concentration plumes that spot monitoring may not fully capture between biweekly retrieval cycles.

Wastewater constituents are the third category of concern, relevant because the Sabine River Operations complex discharges to the tidal reach of the Sabine River. ECHO does not enumerate specific discharge parameters for Orange in the current exporter snapshot [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The Texas Attorney General's February 2026 Seadrift complaint — filed against the same corporate defendants at a separate facility — alleges permit exceedances covering oil and grease, total suspended solids, and nitrogen parameters. Those constituent categories provide a reference frame for the types of pollutants regulated under Dow's Texas wastewater permits more broadly [source: https://www.insurancejournal.com/news/southcentral/2026/02/19/858741.htm].

The EPA ECHO peer benchmark query for NAICS 325211 (Plastics Material and Resin Manufacturing) returned no populated peer rows in the research bundle, so a quantitative rank of Dow Sabine River Operations against its top NAICS peers cannot be computed from available data. What the record does establish is that the Orange site is one of four Gulf Coast Dow plants operating under the January 2021 Clean Air Act consent decree, alongside facilities in Plaquemine, Louisiana; Hahnville, Louisiana; and Freeport, Texas [source: https://www.epa.gov/enforcement/dow-chemical-company-performance-materials-na-inc-and-union-carbide-corporation-clean]. A rigorous NAICS peer comparison would require pulling ECHO exporter rows for LyondellBasell, ExxonMobil Chemical, Formosa Plastics, INEOS, and Westlake at the 325211 level, which was not included in the research bundle [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

No SEC 10-K or 10-Q filings were included in the research bundle for this entity. The EPA ECHO record lists the ticker as private and CIK as N/A, consistent with Sabine River Operations being a facility of The Dow Chemical Company rather than a separately reporting issuer [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. Forward-looking environmental risk for the Orange site is therefore best inferred from three sources: the active consent decree obligations that remain in force, the ongoing fenceline monitoring publication requirements that will continue generating publicly available benzene data, and the parallel state enforcement activity against the same corporate defendants at other Texas sites such as Seadrift [source: https://www.epa.gov/enforcement/dow-chemical-company-performance-materials-na-inc-and-union-carbide-corporation-clean] [source: https://www.insurancejournal.com/news/southcentral/2026/02/19/858741.htm].
