INDORAMA VENTURES OXIDES - PORT NECHES OPERATIONS

Indorama Ventures Oxides — Port Neches Operations (EPA Registry ID 110000599567; 2102 TX-136 Spur, Port Neches, TX 77651) is a Clean Air Act major source and RCRA hazardous-waste handler operating within NAICS 325110 Petrochemical Manufacturing. EPA ECHO data accessed 2026-05-04 shows 8 quarters with non-compliance over the trailing 24 months and derived penalties of approximately $4.88 million, against a 5-year total penalty figure of $12,155,245 and four formal enforcement actions aggregated by third-party compliance tracker PollutionScan [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx] [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The facility carries a composite compliance grade of F (17/100) on PollutionScan's scoring, driven by persistent Clean Water Act and RCRA Hazardous Waste quarter-over-quarter violation codes [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx].

On approximately 2026-04-30, the Texas Commission on Environmental Quality assessed an $18,625 penalty against Indorama Ventures Oxides LLC for the Port Neches site as part of a four-facility Southeast Texas enforcement package covering air and water releases [source: https://www.12newsnow.com/article/news/local/tceq-fines-four-southeast-texas-companies-pollution-beaumont-port-neches-orange/502-95bde746-b029-482c-8a9b-fd84c45fd404]. That state action arrived while parent company Indorama Ventures PCL — Bangkok-listed, with U.S. holdings routed through Indorama Ventures USA Holdings LP — was publicly articulating a 2026 'execution era' strategy built around operational discipline and measurable performance [source: https://indianchemicalnews.com/petro-chemical/indorama-ventures-doubles-down-on-execution-era-strategy-30174]. The Port Neches facility's EPA compliance record over the reporting window tells a different story. Eight non-compliant quarters, $12.16 million in five-year federal penalties, and a fresh state fine issued within weeks of the parent's strategy announcement together form a compliance picture that diverges sharply from the group's stated direction.

The Port Neches Operations site is registered in EPA's Facility Registry Service under multiple program flags — Clean Air Act, Clean Water Act, RCRA Hazardous Waste, and Safe Drinking Water Act — and carries Major Facility classification across all of them [source: https://frs-public.epa.gov/ords/frs_public2/fii_query_detail.disp_program_facility?p_registry_id=110000599567] [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. The RCRA handler ID TXD008076846 places the site in EPA's CIMC profile as a registered hazardous-waste handler, with records in EPA's system dating through at least December 2021 [source: https://ofmpub.epa.gov/apex/cimc/f?p=CIMC%3ARCRA%3A%3A%3A%3A%3AP14_RCRA_HANDLER_ID%3ATXD008076846]. ECHO data as of 2026-05-04 puts the facility's most recent permit action at 2023-12-20 and shows zero currently active permits in the snapshot, though Major Facility status across Clean Air and RCRA programs remains intact [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

The quarterly compliance record across the trailing 24 months is where the pressure concentrates. Third-party aggregation of EPA quarterly compliance records shows Clean Water Act quarter codes dominated by 'u' (unresolved/violation) and 'v' (violation identified) markings for roughly 10 of the most recent 13 reported quarters. RCRA Hazardous Waste quarter codes show persistent 'u' designations across approximately 11 of those same 13 quarters [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. Clean Air Act quarter codes over the same window show 's' markings throughout — steadier, though the marker legend's precise meaning depends on program context. Total inspections logged in the 5-year window: 7. Formal enforcement actions logged: 4 [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx].

The most recent enforcement action arrived at the state level. TCEQ announced on approximately 2026-04-30 an $18,625 fine against Indorama Ventures Oxides LLC at 2701 Spur 136, Port Neches, as part of a package that also penalized Dow Chemical's Port Neches complex and two additional Southeast Texas operators for pollutant releases and failures to meet state air and water standards [source: https://www.12newsnow.com/article/news/local/tceq-fines-four-southeast-texas-companies-pollution-beaumont-port-neches-orange/502-95bde746-b029-482c-8a9b-fd84c45fd404]. That state-level action sits alongside the larger federal 5-year penalty aggregate of $12.16 million and four formal federal actions previously recorded [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. EPA's Toxics Release Inventory system also shows a related sister site — Indorama Ventures Oxides LLC at 3892 US Hwy 90, Dayton, TX (TRI ID 77535BKRPRUSHWY) — filing a 2022 TRI Pollution Prevention Report for naphthalene, indicating reportable-threshold chemical handling within the broader U.S. operating platform [source: https://enviro.epa.gov/enviro/p2_ef_query.p2_report?Opt=0&chemicalId=0000091203&docCtrlNum=&facilityId=77535BKRPRUSHWY&pPrintView=1&reportingYear=2022]. Taken together, the 24-month pattern is clear: Clean Water Act and RCRA compliance are the dominant exposure areas; Clean Air Act status is steadier on the aggregator's ledger.

The most recent action is the TCEQ penalty announced on approximately 2026-04-30: $18,625 assessed against Indorama Ventures Oxides LLC at 2701 Spur 136, Port Neches, TX, as part of a TCEQ four-facility Southeast Texas enforcement announcement covering air and water pollutant releases and standard exceedances [source: https://www.12newsnow.com/article/news/local/tceq-fines-four-southeast-texas-companies-pollution-beaumont-port-neches-orange/502-95bde746-b029-482c-8a9b-fd84c45fd404]. The publicly reported article does not specify pollutant species, release tonnage, or the underlying order number; readers should consult the TCEQ agreed-order docket for the specific citation.

The federal picture is larger. Over the trailing five years, the Port Neches site has accumulated $12,155,245 in total penalties, 4 formal enforcement actions, and 17 violation-quarters logged across CWA, RCRA, and related programs at EPA Registry ID 110000599567 [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. The ECHO-derived 24-month penalty allocation — prorated at 24/60 of the 5-year figure per the derivation noted in the ECHO snapshot — comes to approximately $4,883,581 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. That figure is a derived estimate, not a single enforcement settlement total. Precise allocation of penalty dollars to specific actions requires the formal-action detail records in ECHO's enforcement case file.

Program-level breakdown per the PollutionScan aggregation of EPA quarter codes: Clean Water Act shows violation or unresolved codes in approximately 10 of the last 13 reported quarters; RCRA Hazardous Waste shows violation or unresolved codes in approximately 11 of the last 13 reported quarters; Clean Air Act shows in-status codes throughout the displayed window [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. The ECHO snapshot records 8 violation quarters in the 24-month window, consistent with a continuous pattern of multi-program non-compliance rather than isolated events [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Indorama Ventures Oxides — Port Neches Operations (2102 TX-136 Spur / also cited as 2701 Spur 136, Port Neches, TX 77651, Jefferson County; EPA Registry ID 110000599567; RCRA Handler ID TXD008076846) is the subject facility. ECHO lists 8 violation-quarters in the trailing 24 months and an approximate $4.88 million derived 24-month penalty figure, against a 5-year aggregate of $12.16 million and 4 formal actions [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip] [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. RCRA and CWA are the active compliance-pressure programs. The site carries Major Facility classification [source: https://frs-public.epa.gov/ords/frs_public2/fii_query_detail.disp_program_facility?p_registry_id=110000599567]. EJ index values are not populated in the ECHO snapshot — ej_index_avg is recorded as 0.0 — which signals absent data in the exporter feed rather than a measured zero exposure. Jefferson County, TX includes census blocks historically flagged in EPA EJScreen for elevated air-toxics and cancer-risk percentiles; readers should pull EJScreen directly for block-level context.

One affiliated site adds relevant platform-level context. Indorama Ventures Oxides LLC at 3892 US Hwy 90, Dayton, TX 77535 (TRI ID 77535BKRPRUSHWY) — operated under the same Indorama Ventures USA Holdings LP parent structure as Port Neches — filed a 2022 TRI Pollution Prevention Report covering naphthalene, indicating reportable production-related waste management of that chemical [source: https://enviro.epa.gov/enviro/p2_ef_query.p2_report?Opt=0&chemicalId=0000091203&docCtrlNum=&facilityId=77535BKRPRUSHWY&pPrintView=1&reportingYear=2022]. Naphthalene is classified by EPA as a possible human carcinogen under the IRIS program. The Dayton site sits outside the Port Neches ECHO record, but it is relevant context for assessing environmental performance at the parent level.

The ECHO snapshot returned by the query contains only one facility (facility_count = 1) mapped to this subsidiary; no additional Indorama Ventures Oxides sites were bundled into the per-facility dataset for this briefing [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. A fuller Indorama Ventures USA Holdings LP corporate-family rollup would require a parent-organization query against FRS.

The ECHO snapshot did not return a populated top_pollutants array for Port Neches Operations, so pollutant-specific tonnage at the subject site cannot be stated from the current research bundle [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. Three pollutant categories are nonetheless indicated by the program mix — CAA, CWA, RCRA — and by the TRI filing at the sister Dayton site.

Naphthalene is the most precisely documented chemical in the platform's EPA record. The Dayton facility filed a 2022 TRI Pollution Prevention Report covering naphthalene under TRI ID 77535BKRPRUSHWY [source: https://enviro.epa.gov/enviro/p2_ef_query.p2_report?Opt=0&chemicalId=0000091203&docCtrlNum=&facilityId=77535BKRPRUSHWY&pPrintView=1&reportingYear=2022]. EPA classifies naphthalene as a volatile aromatic hydrocarbon; inhalation is the primary exposure pathway for fence-line communities. Production-related waste-management disclosure is required above TRI de minimis thresholds, so the filing confirms the chemical was handled at reportable scale.

RCRA-regulated hazardous waste is the second category. Port Neches Operations is an EPA-registered hazardous-waste handler under ID TXD008076846, with persistent RCRA quarter-code violations across the 24-month window [source: https://ofmpub.epa.gov/apex/cimc/f?p=CIMC%3ARCRA%3A%3A%3A%3A%3AP14_RCRA_HANDLER_ID%3ATXD008076846] [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. RCRA violations typically concern container management, manifest discrepancies, land-disposal restrictions, or tank-system integrity. The specific subpart citations sit in the TCEQ and EPA enforcement case files rather than the aggregator summary.

Clean Water Act discharges form the third category and show the most concentrated pattern of non-compliance across the quarterly record [source: https://pollutionscan.com/facility/110000599567/indorama-ventures-oxides-port-neches-operations-port-neches-tx]. Port Neches Operations discharges into the Neches River and Sabine-Neches estuary system, a 303(d)-listed waterbody complex in portions monitored by TCEQ. Jefferson County, TX carries elevated demographic and health burden scores in EPA EJScreen national percentiles across multiple indices; fence-line residents include communities in Port Neches, Groves, and Port Arthur. The contextual EJ reporting on Texas petrochemical expansion published by Public Health Watch on 2025-12-30 documents community health-risk concerns tied to the Gulf Coast petrochemical buildout [source: https://publichealthwatch.org/2025/12/30/texas-petrochemical-expansion].

The NAICS 325110 peer benchmark table returned empty in the research bundle, so a quantitative peer ranking by violation_count_24mo and penalty_total_24mo cannot be constructed for this briefing. What the available data does show is that Port Neches Operations sits inside a Gulf Coast petrochemical corridor where multi-facility enforcement is active and ongoing. The TCEQ enforcement cycle announced approximately 2026-04-30 swept in Dow Chemical's Port Neches complex alongside Indorama Ventures Oxides LLC and two additional Southeast Texas operators, all cited for air and water pollutant releases [source: https://www.12newsnow.com/article/news/local/tceq-fines-four-southeast-texas-companies-pollution-beaumont-port-neches-orange/502-95bde746-b029-482c-8a9b-fd84c45fd404]. That corridor context matters: enforcement pressure in this geography is not isolated to a single operator. A full peer ranking requires pulling the ECHO exporter for all NAICS 325110 Texas Major Facilities, which is outside the current dataset [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

No SEC filings are available for direct 10-K Item 1A extraction. Indorama Ventures USA Holdings LP is a private entity and no CIK was identified in the research bundle. Parent Indorama Ventures PCL is listed in Bangkok and does not file 10-K forms with the U.S. SEC. Forward-looking environmental risk disclosure at the parent level appears in the company's own investor communications around the 'execution era' strategic reset and the SOAR approach. Both frameworks emphasize operational discipline. Neither quantifies U.S. environmental-liability reserves or pending enforcement exposure at the Port Neches site [source: https://indianchemicalnews.com/petro-chemical/indorama-ventures-doubles-down-on-execution-era-strategy-30174] [source: https://www.hydrocarbonprocessing.com/news/2026/03/indorama-ventures-outlines-soar-approach-to-boost-chemicals-production-business/]. That absence is material for analysts trying to size the liability. The five-year federal penalty total of $12,155,245, four formal enforcement actions, and an active state enforcement cycle in 2026 Q2 together represent a forward exposure that the parent's public disclosures do not address in dollar terms. Analysts seeking a disclosed reserve figure for Port Neches environmental liabilities should consult the parent's Bangkok-listed annual report; this briefing cannot cite a U.S. SEC equivalent.
