What is MT Department of Environmental Quality?

Montana Department of Environmental Quality services on agency host Five curated data services layers from the ~80-service Hosted folder: Montana_UST_Facilities_/0 UST registry (~1,131 facilities — fac_code/fac_name/fac_addr/fac_city/fac_state/fac_zip/fac_tank_cnt/fac_permit_exp_date); Montana_Tank_Substance_Releases_/0 PTC Releases (~4,512 cleanup events — 4 release_status values Resolved 3,659 / Open 827 / Rescinded 15 / Reopened 11; 2 release_lead_program values: PTC - Petroleum Storage Tank Cleanup 4,474, CPRS - Petroleum Storage Tank Cleanup 38; release_source and release_cause have leading-space prefixes upstream); Montana_FACTS_Permits/0 MPDES Water Discharge Permits (~2,732 — 27 permittype values led by Storm Water Construction 997, 318 Authorization 592, Industrial Stormwater 315, CAFO 119, Ground Water Domestic 92, 401 Cert 42; 3 externalpermitstatus values: Effective 1,639, Expired 918, Admin Continued 175); Montana_Air_Quality_Monitoring_Data_REV24/0 (~21,333,440 hourly readings across 33 monitoring sites including Billings Lockwood, Bozeman, Butte, Missoula, Helena, Kalispell, Great Falls, NCore, Libby, Hamilton, Lewistown, etc. — top parameters: TEMP_AMB_C 3.3M, RM_TEMP 2.5M, PM25 2.4M, WSIGMA 1.8M, WDIR 1.7M, WSPD_MS 1.7M, PM10_STD 1.6M, PM10_ACT 1.5M, O3 808K, NO 668K, NO2 548K, NOX 514K, SO2 326K, CO 227K; 6 EPA AQI healthcategory bands: Good 3.55M, Moderate 388K, USG 33.8K, Unhealthy 16.2K, Hazardous 1.7K, Very Unhealthy 1.0K); Montana_Hazardous_Waste/0 RCRA generator list (~3,092 with epa_fac_code RCRA ID + NAICS coding + fac_county UPPERCASE column). §0 surprises: native CRS is EPSG:32100 (Montana State Plane); Host agency host has historically been flaky — handler retries once on 5xx/HTML/socket-hang-up/ECONNRESET. UST_Facilities, PTC_Releases, FACTS_Permits all have NO county column — only address/city/state/zip + lat/lon (use bbox/near for spatial filtering). Hazardous_Waste DOES have fac_county. PTC release_source/release_cause have leading-space prefixes (' Tank', ' Malfunctioned or Failed Component') — handler trims via asString. Air Quality is enormous (21.3M rows, 7+ years hourly) — handler enforces narrower default limits and orders datetime DESC. on every layer. Last verified live 2026-05-08.
