The Colorado Oil and Gas Conservation Commission (COGCC) has prepared this model sampling and analysis plan for parties who engage in sampling and analysis activities for Rule 609 - Statewide Groundwater Sampling and Monitoring and Rule 318A.e(4) - Groundwater Baseline Sampling and Monitoring in the Greater Wattenberg Area (GWA). This document will be modified as necessary based on new procedures, protocols, and other information that need to...

The Colorado Oil and Gas Conservation Commission is directed to use a risk-based strategy to inspect oil and gas facilities. The Commissions risk-based strategy prioritizes the phases of oil and gas operations that are most likely to experience spills, excess emissions, and other types of violations for inspections. The purposes of a risk-based inspection strategy are to protect public health, minimize environmental contamination, detect spills before...

The Colorado Oil and Gas Conservation Commission (COGCC) currently has several rules, policies and procedures that, when implemented properly, are intended to result in wellbore integrity. "Wellbore integrity" is a system configuration, including casing, cement, annular fluid, and surface appurtenances (e.g., valves, piping, and emission control devices) to protect against infiltration and prevent the migration of oil, gas or water from one horizon...

2016 Colorado ballot initiative #78 proposes a 2500-foot mandatory setback between an oil and gas development facility (including oil and gas wells, injection wells, production and processing equipment, and pits) and any "occupied structure(s)" and "area(s) of special concern" through an amendment to the state's constitution. This regulatory change would be applied to all new oil and gas development facilities in Colorado, and any operation that used...

This staff report analyzes and describes the "lessons learned" about Colorados oil and gas industry and the work of Colorado Oil and Gas Conservation Commission during and after the flood of September 2013. The COGCC estimates that more than 5,900 oil and gas wells lie within 500 feet of a Colorado waterway that is substantial enough to be named. When these streams flood nearby oil and gas facilities are at risk of damage, spills, environmental...

The mission of the Colorado Oil and Gas Conservation Commission ("Commission") is to foster the responsible development of Colorado's oil and gas natural resources. In Colorado, this means that the development of these natural resources must be consistent with protection of public health, safety, and welfare, including the environment and wildlife resources, at all times.

The purpose of this document is to explain key aspects of the rules, regulations, practices, procedures, and policies pertaining to mechanical integrity testing for both idle oil and gas wells and Class II underground injection control (UIC) wells within the State of Colorado.
