Two Dot successfully completed a Pit Closure plan per Colorado Oil and Gas Conservation Commission (COGCC), U.S. Environmental Protection Agency (EPA), and Colorado Department of Public Health and the Environment (CDPHE) regulations. After Two Dot collected contaminated soil samples from a cuttings pit in southern Colorado, compliance measures were implemented to remove liquid and solid waste. Offsite disposal was permitted, the pit closure plan was approved, and final reclamation was completed to release the site from the SWMP and CDPS general permits.
Because levels of Hydro-carbons and Arsenic were so high COGCC, CDPHE, and EPA considered this Hazardous Type “B” waste. Two Dot coordinated with agencies to develop a “Clean Closure” protocol and worked with agencies to begin Site Investigation and Remediation Requirements under Rule 909b. After baseline soil samples and pit soil samples were analyzed, Two Dot completed a Liquid waste Profile form, Solid Waste profile form, and provided agencies a summary of Solid and Liquid waste lab analysis results. Once Two Dot completed the Site Investigation and Remediation Work plan, the cuttings pit was released, materials were removed, and final reclamation was initiated. Two Dot provided the final reclamation plan and the site was released from its CDPHE and WQCD Discharge Permitting System (CDPS) general permit for Stormwater Discharges Associated with Construction Activity.
