Alabama Department of Environmental Management permits + UST + brownfields + Justice40 + complaints via gis.adem.alabama.gov. 5 curated layers from ADEM's 110+ MapServer catalog. - searchPermits ⭐ 83.7K AEPACS records across 42 categories (NPDES, MS4, air, UIC, scrap tire, CAFO, ...) - searchUSTSites ⭐ 10.3K UST facilities (FIPS or name) - searchBrownfields ⭐ 776 ADEM brownfield events - searchComplaints ⭐ 13K public complaints (AIR/COASTAL/LAND/WATER) - searchJustice40Tracts (655) §0: AEPACS uses ESRI_OID + duplicate object_id.

Clearfork Intelligence — curated Texas & New Mexico oil & gas well data, TX drilling permits, and monthly production history with enrichment (aggregated production stats, SB-1150 "zombie well" exposure, canonical well IDs, radius + batch lookup). A cleaned commercial layer complementing the public rrc/nmocd connectors. AUTH: PAID Bearer token (key format cfork_live_...). Set CLEARFORK_BEARER_TOKEN. Requires an Operator ($249/mo) or Enterprise ($499/mo) plan; the permits methods are Enterprise-only. getServiceInfo works without a key (hits the public /health endpoint).

North Dakota DMR (Bakken/Three Forks) oil & gas. AGOL mirror of NDIC public well data; no auth. - searchWells (~25.5K) ⭐ filter by county, operator, status (A/PA/DRY/Confidential), well_type, township/range/section - searchPermits ⭐ wells in LOC/DRL/PNC/EXP permit states - getWellByApi, searchHorizontalLegs (~15.8K Bakken laterals), searchProductionByField, searchSpills, getServiceInfo upstream quirks: native dmr.nd.gov fee-services 401, working data is on AGOL sbogan_worldmap mirror. county UPPERCASE, status enum opaque codes (A/PA/DRY/Confidential), api lossy on production layer (use api_no on wells), horizontal legs only have linekey (api_LATn). Spills come from the FracTracker mirror — 2014-era extract, no live updates.

New Zealand petroleum permits, wells, and geophysical surveys from NZ Petroleum & Minerals (MBIE). Covers active prospecting, exploration, and mining permits — primarily Taranaki Basin. 1,267 wells and 38 active permits. Production volumes are published separately by MBIE (PDF/Excel); this connector covers spatial and regulatory data only.

Oklahoma Corporation Commission (OCC) live ArcGIS REST. No auth. 26 methods, 49 layers. DOMAINS: - Wells: searchWells, getOrphanWells, getStateFundsWells, getWellLogs, getCompletions, getHorizontalLaterals, getUICWells. - Permits: getPermits (ITD). - Units/Rules: getDrillingUnits, getFieldRules. - Seismicity: getInducedSeismicity({zone}). - Surface: getFacilities, getOilGasIncidents, getGasStorage, getPSTTanks/Releases. - Water: getHydrology, getBaseTreatableWater, getPublicWaterSupplyWells/Intakes, getGroundwaterWells. - Geology/Cadastral: getSedimentaryBasins, getCadastral, getDistricts. - Generic: queryLayer({layer,...}) for any listLayers() key. Returns {features, geojson, total}. geojson → patchops_addMapLayer. Page cap 2000. Production volumes at OK Tax Commission.

Pennsylvania DEP Bureau of Oil & Gas Management. PA's quirk: O&G regulator lives under DEP. - searchWells (~25K Unconv + ~199K Conv) ⭐ filter county/operator/status/wellType/wellConfig/wellCategory - searchPermits ⭐ wells with PERMIT_DATE in window (default unconv, last 365d) - getWellByApi, searchOrphanedWells (~27K), searchViolationsAndComplaints, getServiceInfo upstream quirks: PA does NOT use 14-digit API — wells keyed by PERMIT_NUMBER like '003-22621'. WELL_STATUS: Active / Plugged OG Well / Operator Reported Not Drilled / DEP Orphan List. WELL_CONFIG: Vertical (199K conv) / Horizontal (23K unconv) / Deviated. DEP does NOT publish violations Feature Service — Complaints (~39K) used as proxy. Production NOT a Feature Service (XML only) — dropped.

US Army Corps of Engineers public datasets. No auth. - searchDams (NID, ~91k dams via bulk CSV, 24h cache) - getRegulatoryDistrict (point lookup → 1 of 39 districts for Section 404 routing) - searchLevees, searchLocksAndDams, searchNavigationFacilities, searchFUDS, searchCorpsProjects - getWetlandRegion (point lookup → wetland supplement region) - getReservoirStatus (CWMS — current pool % for flood/conservation/total) Federal scope: dams, levees, locks, navigation, defense cleanup, civil works projects, reservoir pool levels, wetland-rule supplements. IENC layers have no state/county columns — use bbox or near. CWMS reservoirs and Corps projects also lack STATE; state filters fall back to bbox or district mapping.

Utah DOGM — O&G regulator. Uinta Basin operator side (Crescent / Ovintiv / KODA). - searchWells ⭐ ~40K surface wells with operator/county/status/cumulative - searchBottomHoles ⭐ ~33K bottomhole locations (deviated wells) - searchWellPaths ~12.5K directional drilling polylines - getWellByApi single-well lookup by 10-digit API upstream quirks: AGOL services.arcgis.com/ZzrwjTRez6FJiOq4 owner OGMGIS_utahDNR. Surf County is UPPERCASE STRING ('DUCHESNE'); BottomHole County is INTEGER code (Duchesne=7 / Uintah=24 / San Juan=19). Paths layer has only API + ConstructStatus (no operator/county). O&G permits are NOT a Feature Service — searchPermits dropped; APD-status wells (1772) are the substitute via searchWells.
