About this file
This is a project documentation file related to remediation activities at the Margaret Spaulding Location in Jackson County, presented by CM Production LLC and the Colorado Oil and Gas Conservation Commission (COGCC). The document provides a visual and narrative overview of CM Production LLC's remediation progress spanning from 2013 to the present, with specific focus on closure activities at the Lone Pine Pit. The file includes site inspection photographs and project location drawings dated from May 2013 through March 2016, documenting various remediation components including Pit 5, a treater pit, soil stockpile, land application site, and injection wells (Margaret Spaulding 4-B and Entrada 1-28). The presentation was delivered by Alex Fischer, COGCC Western Environmental Supervisor, on September 30, 2015, utilizing exhibits from multiple site visits and inspections conducted between May 2013 and March 2016.
The project location operates under significant environmental constraints that directly impact the remediation timeline and execution strategy. The site sits at ground elevation of approximately 8,230 feet and experiences extended winter conditions, including five months of annual snow cover (December through April) and below-freezing temperatures for seven months per year. Consequently, the remediation work must be concentrated within the five-month field season from May through November to achieve effectiveness. The Margaret Spaulding Location is classified as a sensitive area due to its proximity to surface water, which necessitates careful environmental management and compliance with applicable water protection standards throughout all remediation activities.

Short Field Season
• Ground elevation is ~8230’
• Five (5) months of snow cover per year, Dec. - April
• Below-freezing temperatures seven (7) months per year
Therefore the months of May – Nov. must be utilized effectively
Margaret Spaulding Location is in a Sensitive Area
• Proximity to surface water (<500’ to Spring Gulch)
• Shallow groundwater (11 to 32 feet)
• Hydraulic conductivity of underlying clayey sand and gravel
• Concentrations* of total petroleum hydrocarbons (TPH) in Pits, Stockpile, and Landfarm
- Free-phase hydrocarbons observed inside of pits
*Table 910-1 maximum allowable TPH Concentration: 500 mg/kg
