Evergreen Natural Resources - Underworld Gas Extraction Facility, Cokedale, Colorado

Evergreen Natural Resources - Underworld is a gas extraction facility located in Las Animas County, Colorado, approximately 5.6 miles west of Cokedale. The facility is operational and situated in a region with a long history of natural gas production, contributing to the local energy supply chain. As a gas extraction site, the facility operates under the regulatory framework of the US Pipeline and Hazardous Materials Safety Administration (PHMSA) and DOT 49 CFR Part 192, which governs pipeline safety and integrity. The facility's NAICS codes (211111 and 211130) indicate crude petroleum and natural gas extraction, as well as natural gas liquid extraction, reflecting its role in upstream gas production. The facility's location in southeastern Colorado places it within the Raton Basin, a known coalbed methane and natural gas producing area. Its operational status and proximity to transportation infrastructure support its role in regional gas supply, serving both local and broader markets.

The facility is located in a semi-arid region of Colorado, where water availability and land use are key environmental considerations. Gas extraction activities can impact local air quality through emissions and may affect groundwater resources if not properly managed. The area's seismic risk is low, but the facility's proximity to populated areas (Cokedale) and potential for methane leakage are factors in its environmental profile.
