Provide history of all downhole well activities, to include frac jobs, well cleanings, well maintenance, etc. for a period of 7 years. Provide list of chemicals used, including quantities and MSDS's. 


Submit a Form 27 Site Assessment & Remediation Plan detailing a sampling and analysis plan (SAP) to assess potential soil impacts on the pad, at the point(s) of flow exit from the pad and onto the adjacent properties. Initial SAP needs to address soil sampling to include all COGCC Table 910-1 constituents, plus herbicides and chemicals identified in items 1 & 2. Upon COGCC approval, implement plan.

Alleged Violation:
Date of Alleged Violation:  12/5/2011Approx. time of violation:  
 On December 5, 2011, a Form19 for a spill which occurred on 11/20/2011 included three background samples (reportedly not in the 11/20/2011 spill path) collected from the disturbed area of the pad. Two of the samples had arsenic levels of 25 mg/kg and 15 mg/kg. These arsenic concentrations are above the Table 910-1 level (0.39 mg/kg) and above background soil arsenic concentrations in Colorado for Native Grassland, Rangeland, or Agriculture of 3-14 mg/kg, according to the Colorado Department of Public Health and Environment (CDPHE) �Risk Management Guidance for Evaluating Arsenic Concentrations in Soil� (June 2010). The other background sample, not in the spill path, had an arsenic level of 5.5 mg/kg, indicating non-impacted material. The sample results indicate a previous spill on this pad which was not reported and was not remediated to meet Table 910-1 levels.

Act, Order, Regulation, Permit Conditions Cited:
 324.A.a, 906.a, 906.e.2, 907.a (1), 909.b.5

Abatement or Corrective Action Required to be Performed by Operator
 1. Review operational history at pad to identify possible previous releases and potential sources of elevated arsenic. 2. Prepare a Form 27 Site Investigation and Remediation Workplan for COGCC approval prior to implementation. The plan shall include a sampling program to delineate the vertical and horizontal extent of soil concentrations above Table 910-1 levels for full Table 910-1 constituents. 3. Provide written description and diagrams of surface geology and soils present at this location. 4. Perform a background study at this location. Background samples must be collected from undisturbed, native materials. 5. Prepare an interpretive report including the results of tasks 1 through 4 and the "background" samples reported for the 11/20/2011 spill. A one month extension has been granted from 1/20/2012 until 2/20/2012 on LSO 1/20/2012
