HOWELL D353S/HOWELL D4A TWINNED LOCATION

Howell D353S/Howell D4A Twinned Location is a single-site natural gas extraction operation classified under NAICS 211130 and headquartered in Aztec, New Mexico, registered in EPA's Facility Registry under ID 110043976105 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. ECHO's quarterly compliance derivation returns zero formally coded violations in the trailing 24 months. It also assigns an apportioned penalty figure of $3,760,000, calculated as total_5yr*(24/60) per the exporter methodology note — a pro-rata estimate, not a booked settlement [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The facility carries no active federal permits of record in the snapshot dated 2026-05-04. ECHO returns a null environmental justice index and an empty top-pollutants array, which reflects either sub-threshold reporting or gaps in the cross-program linkage rather than an affirmative finding of zero exposure [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

The operator is privately held. No CIK is registered with the SEC, and no 10-K or 10-Q filings are available for Item 1A or MD&A review. Peer benchmarking within NAICS 211120/211130 places the apportioned penalty figure well below the top three regional peers: Greka Bell Compressor Plant at $26.16M, Red Hills Gas Processing Plant at $19.13M across two facilities with eight quarters of non-compliance, and HP Gas Pad at $16.13M with eight quarters of non-compliance [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. No sustainability report, NGO complaint, state-court filing, or media coverage tied to this specific twinned wellsite surfaced in the research bundle across the 365-day window. Readers should treat the penalty apportionment as an accounting artifact pending direct review of the underlying ECHO facility detail page.

The compliance posture of Howell D353S/Howell D4A rests almost entirely on a single federal data artifact: the EPA ECHO Exporter snapshot dated 2026-05-04T17:08:05Z [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. That snapshot records one facility under registry ID 110043976105, zero quarters of formal non-compliance in the trailing 24 months, zero active permits, and an apportioned monetized penalty of $3.76 million derived from a five-year total scaled to a 24-month window [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The derivation formula — penalty_24mo = total_5yr*(24/60) — is disclosed in the exporter metadata. It signals a pro-rata estimate rather than a booked settlement amount specific to the 24-month window [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

A chronological narrative of the past 24 months cannot be reconstructed from public news sources. Brave SERP queries for sustainability reports, NGO litigation surfaces, and state-level violations returned null result sets. Brave news queries tied to the company name and to facility and state scope in the 30-day and 365-day windows returned only unrelated hits — Elden Ring weapon guides, Diablo 4 endgame content, a Bengals NFL draft pick named Cashius Howell, a Howell County (Missouri) sheriff's office announcement, and an obituary for Norvil Howell of Clovis, New Mexico [source: https://www.ozarkradionews.com/local-news/howell-county-sheriffs-office-introduces-new-crisis-intervention-specialist] [source: https://www.legacy.com/us/obituaries/easternnewmexiconews/name/norvil-howell-obituary?id=61316842]. None of those items reference the twinned wellsite, its operator, or natural gas extraction activity in San Juan County, New Mexico.

Exa neural-search for court records and EPA enforcement returned three items. The first is a 1974 Illinois Pollution Control Board matter against The Howell Company, a division of Interlake, Inc., regarding a furniture plant in Saint Charles, Illinois [source: https://pcb.illinois.gov/documents/dsweb/Get/Rendition-143353/unknown]. The second is a closed RCRA administrative docket against DMI Automotive Inc. in Howell, Michigan — Docket RCRA-05-2011-0002, complaint filed 2010-11-03, closed 2011-05-23 [source: https://yosemite.epa.gov/OA/rhc/EPAAdmin.nsf/272e29b668830d488525756200700fa7/bd81fedfe6fa515e852577d1001b7daa!OpenDocument]. The third is an Indiana IDEM agreed order against Honeywell International [source: https://www.in.gov/idem/oe/cause/AO/14638-H.htm]. None of the three match the New Mexico twinned wellsite. The practical consequence is that the compliance record for Howell D353S/Howell D4A within the bundle is limited to a single ECHO row, and any narrative beyond that row requires direct retrieval from the ECHO facility detail page or from New Mexico Environment Department Air Quality Bureau records [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

No discrete enforcement actions with program designation, docket number, complaint date, or settlement amount are available in the research bundle for facility ID 110043976105. ECHO records zero quarters of non-compliance across CWA, CAA, and RCRA program flags in the 24-month window [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The $3,760,000 figure carried in penalty_total_24mo is a derived value — 40% of a five-year total — and its underlying booked settlements, consent decrees, or administrative orders are not itemized in the exporter feed [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

The three enforcement matters returned by Exa neural-search concern unrelated entities entirely. Docket PCB 73-344 before the Illinois Pollution Control Board names The Howell Company for emissions at a furniture manufacturing plant in Saint Charles, Illinois — a 1974 proceeding with no geographic or operational connection to San Juan County [source: https://pcb.illinois.gov/documents/dsweb/Get/Rendition-143353/unknown]. EPA Region 5's RCRA administrative case against DMI Automotive Inc. in Howell, Michigan, Docket RCRA-05-2011-0002, was filed on 2010-11-03 and closed on 2011-05-23 with disposition Payment Received [source: https://yosemite.epa.gov/OA/rhc/EPAAdmin.nsf/272e29b668830d488525756200700fa7/bd81fedfe6fa515e852577d1001b7daa!OpenDocument]. Indiana IDEM Case No. 2005-14638-H names Honeywell International, not any New Mexico gas extraction operator [source: https://www.in.gov/idem/oe/cause/AO/14638-H.htm]. None can be attributed to the San Juan County natural gas wellsite. Analysts requiring action-level detail should pull the ECHO facility detail URL for FRS 110043976105 directly and cross-reference against New Mexico OCD (Oil Conservation Division) and NMED Air Quality Bureau compliance trackers [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Howell D353S/Howell D4A Twinned Location, Aztec, New Mexico (FRS 110043976105): the ECHO exporter returns a single facility row under this operator slug with zero formal quarters of non-compliance, zero active permits of record in the snapshot, an EJ index reported as 0.0, and an empty top_pollutants array [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The $3.76M apportioned penalty is the only monetized data point available. The twinned designation in the facility name suggests two co-located wellheads operating under a single FRS identifier — a common convention for San Juan Basin operations where adjacent wellheads share surface infrastructure. No second, third, fourth, or fifth facility is registered under this operator slug in the bundle; the facility_count field is 1 [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

Regional air-quality context for the San Juan Basin is established — though not specific to this operator — by the NMED-filed Four-Factor Analysis for the Mountainair Compressor Station operated by Transwestern Pipeline Company. That document addresses Regional Haze Rule obligations under 40 CFR §51.300-309 within the same state [source: https://www.env.nm.gov/wp-content/uploads/sites/2/2019/12/AI_1569_11203587-RPT-Mountainair_Four-Factor_FINAL.pdf]. The Mountainair analysis does not name the Howell twinned site. It does establish the regulatory framework that would apply to any material emission source of similar class in New Mexico, making it a useful structural reference for evaluating what compliance obligations could attach to this wellsite if emissions cross reporting thresholds.

ECHO returns an empty top_pollutants array for FRS 110043976105, and no TRI, NEI, or AQS emissions figures are attached in the bundle [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. That data gap does not mean the site emits nothing. For NAICS 211130 natural gas extraction operations in the San Juan Basin, the default pollutant profile of regulatory concern centers on methane (CH4), volatile organic compounds (VOCs), and hydrogen sulfide (H2S) — all governed under the Clean Air Act as administered by NMED. The Mountainair Compressor Station Four-Factor Analysis filed with NMED describes the applicable framework in detail: 40 CFR §§51.300 to 51.309 govern visibility-impairing emissions, with NOx and SO2 as the principal regulated species for the Regional Haze Second Planning Period [source: https://www.env.nm.gov/wp-content/uploads/sites/2/2019/12/AI_1569_11203587-RPT-Mountainair_Four-Factor_FINAL.pdf].

Exposure pathways for upstream gas extraction sites of this type typically include fugitive well-pad emissions, pneumatic controller venting, and flaring events. Each pathway carries distinct monitoring and reporting obligations under federal and state rules. Environmental justice implications in the Four Corners region attach to proximity to Navajo Nation allotments and lower-income rural populations — a geographic reality that makes the EJ index figure here worth scrutinizing. The EJ index of 0.0 returned by ECHO for this specific FRS should be read as an absence of coded data in the snapshot rather than an affirmative finding of no exposure concern [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. Direct TRI and NEI pulls would be required to populate a pollutant-specific profile for this site.

Within the NAICS 211120/211130 peer set pulled from the exporter, Howell D353S/Howell D4A's apportioned penalty of $3.76M is roughly one-seventh of Greka Bell Compressor Plant's $26.16M, one-fifth of Red Hills Gas Processing Plant's $19.13M spread across two facilities and eight quarters of non-compliance, and less than one-quarter of HP Gas Pad's $16.13M across one facility and eight quarters [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. The penalty gap is substantial. Unlike Red Hills and HP Gas Pad, the Howell site records zero quarters of non-compliance in the 24-month window, matching Greka Bell's zero-quarter figure despite carrying a penalty total that is a fraction of Greka Bell's. All four peers return a 0.0 EJ index in the exporter, which reflects snapshot limitations rather than comparative EJ positioning [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip].

No SEC 10-K Item 1A risk factor disclosure is available for this operator. The entity is privately held with no CIK, and the research bundle contains empty dictionaries for 10-K and 10-Q excerpts [source: https://echo.epa.gov/files/echodownloads/echo_exporter.zip]. Forward-looking environmental risk at the facility level would ordinarily attach to Regional Haze Second Planning Period obligations under 40 CFR §51.300-309 as administered by NMED Air Quality Bureau — a framework documented in the Transwestern Pipeline Mountainair Compressor Station four-factor analysis [source: https://www.env.nm.gov/wp-content/uploads/sites/2/2019/12/AI_1569_11203587-RPT-Mountainair_Four-Factor_FINAL.pdf] — and to federal methane rule amendments applicable to NAICS 211130 upstream operators. Those methane rules have tightened since 2022 and carry direct implications for well-pad venting and pneumatic controller configurations of the type common to San Juan Basin sites. Direct Item 1A text for this specific operator is not in the record, and no proxy disclosure from a comparable private operator was located in the bundle.
