12/4/2018 | Lighting on well pad locations is considered temporary and will be used during completion and construction activities. Temporary lighting will be directed downward, inward, and shielded towards location to avoid glare on public roads and building units within 1,000 feet. Lighting will be turned off when practical, i.e., no operations being conducted. On production facilities some lighting will be installed on timers; permanent lighting may be used when necessary. |
| General Housekeeping | Form: (02A )
401795634
12/4/2018 | Housekeeping will consist of neat and orderly storage of materials and fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at offsite, suitable facilities. If spills occur prompt cleanup is required to minimize any commingling of waste materials with stormwater runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans will be used during routine fueling and maintenance to contain spills or leaks. Any waste product from maintenance will be containerized and transported offsite for disposal or recycling. There will be no major equipment overhauls conducted onsite. Equipment will be transported offsite for major overhauls. Cleanup of trash and discarded materials will be conducted at the end of each work day. Cleanup will consist of patrolling the roadway, access areas, and other work areas to pickup trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of properly. |

12/4/2018 | Stormwater BMP’s will be constructed around the perimeter of the site prior to, or at the beginning of construction. Specific BMP’s used may include stockpile stabilization, grading, sediment traps, and perimeter barriers based on final construction design and will remain in place until the pad reaches final reclamation. |
| Dust control | Form: (02A )
401795634
12/4/2018 | Noble shall employ practices for control of fugitive dust caused by their operations. Such practices shall 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 used if technologically feasible and economically reasonable to minimize fugitive dust emissions. |

401795634
12/4/2018 | 1. A contiguous spray liner will be installed and will underlay the entire tank battery. The location of a partially buried cement water vault will be excavated prior to liner install.
2. A 60 bbl cement water vault will be utilized to collect excess produced water from oil tanks. Produced water in the vault will be removed as needed and disposed of in an approved UIC disposal well. The cement water vault is one piece with no seams designed to minimize potential for leaks. All piping associated with the use of the water vault will be aboveground and visually inspected on a regular basis.
3. The partially buried cement water vault will be installed above the spray in liner.
4. A sized steel secondary containment ring will be installed surrounding the entire tank battery. Sand and gravel bedding will be installed to protect the liner prior to placing equipment in the containment area.

12/4/2018 | The operator shall employ sand traps, surge vessels, separators, and tanks during flowback and cleanout operations to safely maximize resource recovery and minimize releases to accommodate green completions techniques.
Operator will use an enclosed combustion device with a 98% design destruction efficiency for hydrocarbons.
When commercial quantities of salable quality gas are achieved at each well, the gas shall be immediately directed to the sales line or wells will be shutin and gas conserved. If a sales line is unavailable or other conditions prevent placing the gas into a sales line, the operator shall not produce the wells without an approved variance per Rule 805.b.(3)C. The Rule 912 notice and approval requirements apply regardless of a variance from Rule 805.b.(3)C.

6/2/2020 | Type: Freshwater MLVTs
Per the June 13, 2014 COGCC Policy on the use of Modular Large Volume Tanks- Noble will have a 3rd-Party Operator construct, operate and monitor the freshwater MLVT structure. The Operator will have an MLVT Design Package, certified and sealed by a licensed PE, on file and available on request. The Operator will comply with all siting, construction, inspection and testing requirements specified in the Design Package and meeting COGCC Policy. Operation of the MLVT within 2,000 feet of a building unit will be shielded by engineered sound walls; this shielding would prevent any additional impacts that would need to be mitigated beyond currently committed BMPs for noise, light and dust impacts. |

4/2/2026 | Pursuant to the COGCC Policy on the Use of Modular Large Volume Tanks (MLVT), Noble will provide certification to the COGCC that the installation and operations of MLVTs will comply with the Design Criteria, Site Preparation & Installation, and MLVT Operations and Contingency Planning outlined in the Policy. The MLVT design package, contractor installation records, records of inspections and associated action items and records of any repairs will be maintained and be available upon request. Daily visual inspections will be conducted per the Policy. Noble’s contingency/emergency response plan has been developed and is available upon request. |
