11/7/2017 | An access route from the highway or county road to the proposed oil and gas location has been prearranged. Required access road permits will be obtained before construction begins and any special requirements outlined by the municipality will be followed. Emergency routes will be chosen prior to the commencement of operations and will be clearly marked and maintained throughout drilling, completion and production activities.

11/7/2017 | Leak Detection Program
• Annual hydrostatic test on the oil dump line from the separator to the tank battery.
• Annual hydrostatic “static” tests on our oil tanks.
• Annual hydrostatic “static” tests on our produced water tank and water dump line from the separator to the produced water tank.
• Lease Operator inspections of all equipment not to exceed 48 hours.
• Monthly documented inspections (EU).
• Annual environmental inspections of all battery and well equipment and pads.
• Annual UT inspections of the pressure vessels and input into Crestone’s RIPL Predictive Integrity Maintenance Program. (HLP separators and fuel gas separators)"

11/7/2017 | Crestone utilizes 24” tall corrugated galvanized metal berm walls with a capacity in excess of 150% of the largest tank contained within the wall. In addition, Crestone best practices mandates the use of impervious liners that extends under each storage tank and up the walls, permanently affixed to the top of the metal berm wall. Protrusions of piping that come through the liner include a fully sealed “boot” to prevent leakage.

11/7/2017 | Crestone will comply with COGCC Rule 1002.f.(2). by utilizing BMPs at the oil and gas location to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, site degradation and protects surface waters.
The location has been constructed using ditch and berms surrounding the area of disturbance. Straw waddles were installed at the perimeter of the location at the base of fill slopes. Inspections are performed bi-monthly or after a significant precipitation event per our CDPHE SWMP. |

11/7/2017 | All newly installed or replaced crude oil and condensate storage tanks shall be designed, constructed, and maintained in accordance with National Fire Protection Association (NFPA) Code 30 (2008 version). Crestone shall maintain written records verifying proper design, construction, and maintenance, and shall make these records available for inspection by the Director. Only the 2008 version of NFPA Code 30 applies to this rule.

11/7/2017 | Crestone will perform a baseline noise survey prior to any operational activity measuring dBA at a distance 350 feet from the noise source or sound levels will be measured at a point twenty-five (25) feet from the structure towards the noise source. In situations where measurement of noise levels at three hundred and fifty (350) feet is impractical or unrepresentative due to topography, the measurement may be taken at a lesser distance and extrapolated to a 350-foot equivalent using the formula stated in Rule 802 of the State of Colorado Oil and Gas Conservation Commission. 40’ sound walls have been installed surrounding the location. Equipment on the pad has also been shielded with smaller sound walls and noise dampening padding. All noise mitigation will remain in place until drilling and completions operations have been completed.
