1/11/2019 | Frequency on valve and fitting inspections: Crestone Lease Operators inspect all equipment on their locations at a minimum of once every 48 hours, but most sites are inspected every 24 hours. Valves and fittings inspections are part of the daily job duties of our lease operators. Any valve or fitting that is found to be leaking is either repaired immediately by the lease operator or shut-in procedures are implemented as described below. Additionally, lease operators conduct a documented monthly inspection of the facility and this includes inspection of all valves and fittings. |

1/11/2019 | Measures for when leaks are discovered:
- If we suspect a leak we shut in the well and hydrotest the line. If it passes, then the well is brought back onto production.
- If there is an actual leak, well is kept shut in while leak is found and fixed. Not until the line has passed hydrotesting, would the well be brought back online. |

• 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.
• UT inspections of the pressure vessels every five years and input into Crestone’s RIPL Predictive Integrity Maintenance Program. (HLP separators and fuel gas separators) |

1/11/2019 | The Crestone lease operator inspections are done as a routine part of the lease operators job. The lease operator would typically visit each of their assigned locations daily. They conduct a visual inspection of the facility which includes all valves, fittings, wellhead, tanks, vapor control systems and all connections. The lease operator also checks our Cygnet automation system for system pressures and flows.
The monthly documented inspection is done using an electronic form that is recorded in the EU system. This inspection and documentation requires the lease operator to inspect all aspects of the site and then triggers work orders for any leaks, or housekeeping issues.
The Lease operators also conduct a weekly CDPHE Regulation 7 – Audible, Visual, and Olfactory (AVO)inspection, which focus on the tanks and vapor control system.
In addition, the sites are inspected with optical gas imaging cameras on a routine schedule, annually for compliance purposes with our Spill Prevention Containment and Countermeasures (SPCC) plan; depending on the status of reclamation the sites are also inspected on either a 14-day, 30-day, annual or rain triggered event in accordance with both the COGCC and the CDPHE Stormwater Management Plans (SWMP). |

1/11/2019 | Crestone will utilize temporary tanks during the flowback phase. There would be as many as 6 oil tanks and 10 water tanks on site for no more than 60 days. All temporary tanks will have vapor recovery that goes to an incinerator and all will be in a lined high-wall berm containment. |
| Dust control | Form: (02A )
401675789
1/11/2019 | Crestone will adhere to COGCC Rule 805.c. concerning fugitive dust. Crestone will employ practices for control of fugitive dust caused by their operations. Such practices will include but are not limited to the use of speed restrictions, regular road maintenance, restriction of construction activity during high-wind days, and silica dust controls when handling sand used in hydraulic fracturing operations. Additional management practices such as road surfacing, wind breaks and barriers, or automation of wells to reduce truck traffic may also be required if technologically feasible and economically reasonable to minimize fugitive dust emissions. Crestone will use a rock base tracking pad at the access point to help remove dirt and prevent debris from collecting on CR 15. As necessary, Crestone will sweep roads nearest the access point of dirt and debris to maintain a clean entrance. Water trucks could also be used to suppress dry soils and dust. |

1/11/2019 | 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. |

1/11/2019 | 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. Examples of engineering controls that could be used when needed are:
o Surface roughening
o Silt fence
o Erosion control blanket
o Temporary slope drain
o Temporary outlet protection
o Sediment control log
o Vehicle tracking control
o Sediment trap
o Stabilized staging area |

1/11/2019 | All newly installed or replaced crude oil and condensate storage tanks will be designed, constructed, and maintained in accordance with National Fire Protection Association (NFPA) Code 30 (2008 version). Crestone will maintain written records verifying proper design, construction, and maintenance, and will make these records available for inspection by the Director. In addition, onsite inspections are conducted internally to insure guidelines are met. |
| Noise mitigation | Form: (02A )
401675789
1/11/2019 | 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. As necessary, based on the survey, Crestone will install temporary sound walls to minimize noise and light impacts during drilling and completions and will install permanent noise mitigation at the facility location as necessary to meet all COGCC regulations. |
