Coiled tubing activities at the Bubba Federal 3N66W5 pad operated by PDC Energy in Weld County, May 2025. Chemical disclosures for this pad were made on June 6, 2025.
Now that the ECMC Chemical Disclosures “database” has data for 158 locations, let’s look at the chemicals disclosed. We previously looked at the chemical disclosure for the Cosslett East location, and found 4 chemicals (by CAS Number) that Crestone Peak Resources had never before listed in their FracFocus disclosures.
As of July 17, 2025, the ECMC Chemical Disclosures data contain 4,735 chemical entries for 158 locations and 172 distinct chemical CAS Numbers. These are the 28 chemicals that have never before been disclosed to FracFocus for any Colorado frac job, according to their CAS Number, as well as their general purpose in oil & gas extraction.

On June 27, 2025, Crestone Peak Resources finally submitted the required chemical disclosures for the hydraulic fracturing jobs at Cosslett East, 5 weeks after PSR/FracTracker’s expose on missing chemical disclosures was published on May 20, 2025. This report was submitted 679 days late; it was originally due on August 18, 2024, 150 days after the last well was spud on March 21, 2023. It’s yet another example where the industry is only held accountable by activist organizations where state regulatory agencies fail to do so.
In a special meeting on June 26, 2025, ECMC representatives announced Notice of Alleged Violation (NOAV) 404256913, issued to Noble Energy Inc as a result of the Bishop A07 blowout incident on April 6, 2025. The NOAV is searchable via the ECMC’s COGIS Incident Inquiry database.
Additional documents regarding the Bishop well blowout are available at the spill and facility doc pages at the ECMC:
As per ECMC regulations, Noble Energy Inc will have an opportunity to respond to the NOAV. While not announced today, we hope the ECMC will announce a significant penalty for this record-breaking environmental disaster, as they did for the Firestone Tragedy.
On Tuesday, May 20, 2025, Physicians for Social Responsibility (PSR), PSR Colorado, Colorado Sierra Club, and FracTracker Alliance released a report that highlighted low compliance with a 2022 Colorado law designed to prevent toxic exposure to the chemicals used in hydraulic fracturing.
Of the 1,114 wells highlighted in the report, 14 of them are located in Erie at the Cosslett East #22H-H168 pad, where wells were drilled and hydraulically fractured in 2023.
At their regularly scheduled April 2, 2025 meeting, the ECMC Commissioners heard an update from Director Julie Murphy about the data integrity/falsification regarding spill sample laboratory analyses by Eagle Environmental Consulting and Tasman, Inc.
This map shows oil & gas locations identified in data published by the Colorado Energy & Carbon Management Commission (ECMC) on April 4, 2025 regarding at least 399 falsified laboratory data reports made to the ECMC since 2015 for spill remediation projects operated by Chevron (279 locations), Oxy (74 locations), and Civitas (46 locations), who contracted environmental testing by Eagle Environmental Consulting, Inc. and Tasman, Inc.Continue reading “ECMC Data Integrity/Falsification Update from Director Murphy”
In the light of recent speculation that Civitas is considering divestment of its Denver-Julesburg Basin assets to focus on the Permian basin in Texas, it’s a good time to review the major players in the basin. Let’s take a look at current assets, recent acquisitions, who’s in a position to acquire these assets, and how the acquisition might impact future development in the Basin.
Of the 344 locations identified by the Energy & Carbon Management Commission (ECMC) that are a part of the data falsification initially reported in November, 2024, 5 are in and around Erie, Colorado. Below are additional details about the spills and remediation efforts at these sites.
At least 404 falsified laboratory reports were made by Eagle Environmental Consulting, Inc. and Tasman, Inc. 55 additional falsified reports were discovered in April 2025, and another 5 were added in July 2025.
