EQUISTAR CHEMICALS LP

Equistar Chemicals, LP, a wholly-owned subsidiary of LyondellBasell Industries, operates under NAICS 325211 (Plastics Material and Resin Manufacturing) with its principal office at 1221 McKinney Street, Suite 700, Houston, Texas [source: https://www.sec.gov/Archives/edgar/data/1081158/000084263508000022/equ10k-032808.htm]. Fourteen EPA-registered facilities — nearly all sited along the U.S. Gulf Coast — define the company's production geography. EPA ECHO data compiled as of 2026-05-11 records 35 quarters with noncompliance across that 14-site footprint in the trailing 24 months, with a derived penalty exposure of $3,333,190 for the same interval [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The ECHO export flags zero active permits; the most recent permit-action date on file is 2018-12-18 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

The enforcement record extends well beyond the 24-month window. On July 19, 2007, EPA announced a multi-state Clean Air Act settlement in Washington, D.C.; the companion Consent Decree, filed in the U.S. District Court for the Northern District of Illinois, established injunctive obligations across Equistar's olefins units in Illinois, Iowa, Louisiana, and Texas [source: https://epa.gov/enforcement/equistar-chemicals-settlement] [source: https://19january2021snapshot.epa.gov/sites/static/files/2013-09/documents/equistarchemicals-cd.pdf]. Those obligations remain operative. State-level proceedings continued alongside them: TCEQ's Agreed Order in Docket No. 2021-0238-IWD-E assessed a $92,710 penalty against the La Porte Complex on Miller Cut Off Road in Harris County for industrial wastewater discharge findings [source: https://www.tceq.texas.gov/downloads/agency/decisions/agendas/backup/2021/2021-0238-iwd-e.pdf]. Measured by trailing-24-month derived penalty totals within the NAICS 325211 peer set, Equistar ranks second — behind Dow – Sabine River Operations at $3,886,600.80 and ahead of Firestone Polymers Lake Charles at $2,680,000 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

EPA ECHO applies a standard methodology: per-facility quarterly noncompliance counts are capped at eight, and five-year penalty totals are prorated to a 24-month window. Applied across Equistar's 14-facility portfolio, that approach yields 35 quarters with noncompliance and a derived penalty exposure of $3,333,190 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. That total falls within the same order of magnitude as the highest-penalty single facility in NAICS 325211 — Dow – Sabine River Operations at $3,886,600.80 — but the comparison requires a structural adjustment. Equistar's exposure is distributed across 14 sites; Dow's concentrates in one. Per facility, Equistar's penalty burden is lower. The geographic spread of compliance risk, however, is wider [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The ECHO export flags no active permits and records the most recent permit-action date as 2018-12-18 — a gap that warrants direct verification against current Title V air operating permits and NPDES wastewater permits at the individual facility level [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

The chronological record opens with an obligation that predates the 24-month window by nearly two decades. The Consent Decree filed in the U.S. District Court for the Northern District of Illinois — with the United States as plaintiff and Illinois, Iowa, and Louisiana as plaintiff-interveners — imposed long-term injunctive relief on flaring, leak detection and repair (LDAR), and benzene waste operations across Equistar's olefins units in the four named states [source: https://19january2021snapshot.epa.gov/sites/static/files/2013-09/documents/equistarchemicals-cd.pdf]. Those obligations remain active. Texas state proceedings ran in parallel: TCEQ's Agreed Order in Docket No. 2021-0238-IWD-E, with an executive-summary date of 2022-04-19, addressed industrial wastewater discharge findings at the La Porte Complex at 1515 Miller Cut Off Road, Harris County. The order assessed a $92,710 penalty and recorded no past-due penalties and no identified third-party interests [source: https://www.tceq.texas.gov/downloads/agency/decisions/agendas/backup/2021/2021-0238-iwd-e.pdf]. The balance of the 24-month enforcement activity in the ECHO export is spread across the remaining facility registry IDs, with no single site accounting for an outsized share.

EPA's Facility Registry Service adds program-level granularity. The FRS Facility Detail Report for registry ID 110000465069 — one of the 14 Equistar-affiliated IDs in the ECHO export — confirms integrated air, water, and waste program coverage, the standard regulatory profile for ethylene and polyolefin production assets [source: https://frs-public.epa.gov/ords/frs_public2/fii_query_dtl.disp_program_facility?p_registry_id=110000465069]. The combination of the carryover Consent Decree, the 2021 TCEQ wastewater order, and the 35-quarter cumulative noncompliance count describes a compliance profile that is stable rather than escalating within the trailing 24-month window. No current-period Equistar 10-K or 10-Q was captured in the research bundle; the company's debt-registered SEC filings appear under CIK 1081158, and the most recent filing available in the bundle is the fiscal-year-2007 10-K [source: https://www.sec.gov/Archives/edgar/data/1081158/000084263508000022/equ10k-032808.htm].

Action 1 — TCEQ Agreed Order, Docket No. 2021-0238-IWD-E, Case No. 59915. TCEQ issued this 1660 Agreed Order under Clean Water Act-delegated industrial wastewater discharge authority. The subject facility is Equistar Chemicals' La Porte Complex, 1515 Miller Cut Off Road, La Porte, Harris County, Texas — approximately one mile north of the Miller Cut Off Road and State Highway 225 intersection. Regulated Entity Number: RN100210319. Operation type: wastewater treatment facility. Total penalty assessed: $92,710. The Texas Register published the order on 2021-09-24. TCEQ recorded no public comments, no past-due penalties, and no additional pending enforcement actions at the time. LyondellBasell Acetyls, LLC is listed as co-respondent [source: https://www.tceq.texas.gov/downloads/agency/decisions/agendas/backup/2021/2021-0238-iwd-e.pdf].

Action 2 — United States of America, et al. v. Equistar Chemicals, LP, U.S. District Court for the Northern District of Illinois, Consent Decree. The United States served as plaintiff; the States of Illinois, Iowa, and Louisiana as plaintiff-interveners. The decree spans two federal programs: the Clean Air Act and the Resource Conservation and Recovery Act's benzene-waste provisions. Its injunctive obligations cover flaring controls, leak detection and repair (LDAR), and benzene waste operations at Equistar's olefins units across all four named states [source: https://19january2021snapshot.epa.gov/sites/static/files/2013-09/documents/equistarchemicals-cd.pdf]. EPA announced the underlying settlement on July 19, 2007, from Washington, D.C. That announcement remains the principal federal enforcement reference for the legacy obligations governing certain plant operations today [source: https://epa.gov/enforcement/equistar-chemicals-settlement].

Action 3 — ECHO-aggregated noncompliance, 14-facility portfolio, May 2024 through May 2026. EPA ECHO reports 35 quarters with noncompliance across the 14 registry IDs, applying its standard per-facility cap of 8 quarters. The derived 24-month penalty allocation is $3,333,190, calculated by prorating reported five-year totals [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. No active permits appear in the current export; the most recent permit-action date on record is 2018-12-18 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. Program-level coverage for representative registry IDs — including 110000465069 — is documented in EPA FRS [source: https://frs-public.epa.gov/ords/frs_public2/fii_query_dtl.disp_program_facility?p_registry_id=110000465069]. The ECHO export does not break the 24-month penalty total down to individual docket numbers; analysts requiring per-docket figures should query each registry ID directly through the ECHO facility-detail interface.

Equistar Chemicals La Porte Complex (Harris County, TX; Registry RN100210319). The La Porte Complex at 1515 Miller Cut Off Road is the most heavily documented Equistar facility in the research bundle. TCEQ's 2021 Agreed Order assessed a $92,710 penalty for industrial wastewater discharge findings — the largest single state-level penalty recorded against an individual Equistar site in the post-2020 data captured [source: https://www.tceq.texas.gov/downloads/agency/decisions/agendas/backup/2021/2021-0238-iwd-e.pdf]. The facility operates as a wastewater treatment installation within a larger petrochemical complex. TCEQ lists LyondellBasell Acetyls, LLC as co-respondent, reflecting the integrated ownership structure at the site.

EPA Registry ID 110000465069 (Equistar-affiliated, FRS-documented). EPA's Facility Registry Service records air, water, and waste program coverage at this registry ID — the standard multi-program regulatory profile for ethylene and polyolefin production assets [source: https://frs-public.epa.gov/ords/frs_public2/fii_query_dtl.disp_program_facility?p_registry_id=110000465069]. This site is one of the 14 facility IDs enumerated in the ECHO export underpinning the company's 35-quarter trailing noncompliance count [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Four additional ECHO-enumerated facility registries — 110012498476, 110001868275, 110043974072, and 110009529796 — are also among the 14 IDs underlying the $3,333,190 derived penalty figure [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. Per-facility violation breakdowns, top pollutants, and EJ index values are not disaggregated in the ECHO export tier used for this analysis. The ej_index_avg field reads 0.0 across the portfolio, which typically signals the field was not populated in the source export rather than an actual absence of environmental-justice exposure (see Stated vs. Measured section).

Legacy olefins units in Illinois, Iowa, and Louisiana subject to the 2007 federal Consent Decree. The Consent Decree filed in the Northern District of Illinois imposes long-term injunctive obligations on flaring controls, LDAR, and benzene waste operations at Equistar's olefins units in Illinois, Iowa, and Louisiana as well as Texas [source: https://19january2021snapshot.epa.gov/sites/static/files/2013-09/documents/equistarchemicals-cd.pdf]. Those obligations continue to define the compliance baseline at each covered unit.

Victoria, Texas (HQ-state operations). Equistar's stated headquarters is in Victoria, Texas, with operational management offices in Houston at 1221 McKinney Street and 16055 Space Center Boulevard, Suite 350 [source: https://www.onevalor.com/operator-services/companies/equistar-chemicals-lp/] [source: https://www.sec.gov/Archives/edgar/data/1081158/000084263508000022/equ10k-032808.htm]. The concentration of facilities along the Texas Gulf Coast and the Mississippi River corridor places multiple Equistar sites in EPA Regions 4, 6, and 7 — areas where EJScreen indices commonly register above-national-median scores on both demographic vulnerability and pollution-exposure measures.

Volatile Organic Compounds (VOCs) and Highly Reactive VOCs (HRVOCs). The 2007 Consent Decree governing Equistar's olefins units targets two control pathways: flaring management and leak detection and repair (LDAR). Those pathways are the primary regulatory mechanisms for limiting fugitive VOC emissions at ethylene crackers and downstream polyolefin units [source: https://19january2021snapshot.epa.gov/sites/static/files/2013-09/documents/equistarchemicals-cd.pdf]. VOCs are ozone precursors. In Gulf Coast airsheds — where much of Equistar's production capacity operates — documented respiratory and cardiovascular health effects are associated with ozone and related photochemical oxidants. EPA's enforcement record identifies VOC-related Clean Air Act compliance as the principal federal enforcement category at issue for the company [source: https://epa.gov/enforcement/equistar-chemicals-settlement].

Benzene and benzene waste streams. The Consent Decree's benzene waste provisions run alongside the Clean Air Act counts, brought under Resource Conservation and Recovery Act authority. Benzene is a known human carcinogen with hematologic toxicity; its waste streams carry established exposure concerns for site workers and fenceline communities alike [source: https://19january2021snapshot.epa.gov/sites/static/files/2013-09/documents/equistarchemicals-cd.pdf]. Benzene controls occupy a central position in the National Emission Standards for Hazardous Air Pollutants (NESHAP) framework applicable to refineries and chemical manufacturers. Those controls define the long-term injunctive obligations Equistar continues to carry under the decree.

Industrial wastewater constituents (process effluent, oxygen-demanding loads). TCEQ's 2021 Agreed Order at the La Porte Complex addressed industrial wastewater discharge from a facility classified as a wastewater treatment operation [source: https://www.tceq.texas.gov/downloads/agency/decisions/agendas/backup/2021/2021-0238-iwd-e.pdf]. Petrochemical discharges into the Houston Ship Channel and adjacent Galveston Bay tributaries carry documented histories of nutrient loading, organic carbon, and trace organics. Specific top pollutants for the Equistar portfolio are not enumerated in the current ECHO snapshot — the top_pollutants field returned empty — which limits pollutant-by-pollutant ranking and warrants direct query of Discharge Monitoring Report (DMR) data for each facility through the ECHO interface [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

In the NAICS 325211/325212 plastics-and-resins peer set drawn from the ECHO export, Equistar ranks second by trailing-24-month derived penalty total at $3,333,190 — sitting between Dow – Sabine River Operations ($3,886,600.80, single facility, 8 noncompliance quarters) and Firestone Polymers Lake Charles ($2,680,000, single facility, 5 quarters) [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The comparison demands a structural adjustment. Dow's $3.9 million and Firestone's $2.7 million each concentrate in a single complex. Equistar's $3.3 million is distributed across 14 sites and 35 noncompliance quarters — a fundamentally different exposure pattern. Per facility, Equistar's averaged 24-month penalty of approximately $238,085 is roughly one-sixteenth of Dow Sabine River's single-facility figure. Its per-facility noncompliance-quarter count of 2.5 falls below both peers when normalized. The ej_index_avg field returns 0.0 across all three companies in the current export. That result reflects missing field population in the ECHO snapshot rather than an actual absence of EJ exposure for these Gulf Coast operators [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

No current-period Equistar Chemicals, LP 10-K Item 1A was captured in the research bundle. The most recent Equistar-specific Form 10-K on record is the FY2007 filing, Commission File No. 333-76473, CIK 1081158 — filed as a Delaware limited partnership registered with the SEC as a debt issuer. Item 1A of that filing identifies environmental laws, climate-change-related regulation, and Clean Air Act and Clean Water Act compliance obligations as material forward-looking risk categories for integrated petrochemical operators; it also acknowledges ongoing obligations under federal consent decrees [source: https://www.sec.gov/Archives/edgar/data/1081158/000084263508000022/equ10k-032808.htm]. Current-period forward-looking environmental risk disclosures for the Equistar operating footprint appear within parent LyondellBasell Industries N.V.'s consolidated SEC filings. Those filings were not captured in the present research bundle and should be retrieved separately before drawing any analyst conclusion on present-day Item 1A language.
