| Dust control | Form: (02A )
403355947
1/24/2024 | 1. On Location, Dust suppression during periods of continuous operations will be accomplished by the application of water to the well pad and exposed earthen surfaces to reduce the transportability of dust when atmospheric conditions are conducive to sustained winds and/or periodic gusts. All dust suppression efforts will consist of only freshwater unless otherwise requested and approved as applicable.
2. Off Location, Dust suppression during periods of continuous operations will be accomplished by the application of Weld County approved methods to the access road(s) and haul route to reduce the transportability of dust when atmospheric conditions are conducive to sustained winds and/or periodic gusts. All dust suppression efforts will consist of, but may not be limited to, the use of mag-chloride and/or the use of a dust suppressant.
3. To minimize sand-related dust emissions, the Operator will be utilizing containerized box technology for sand transport, storage and use during the completions phase. These sand containers (or “sandboxes”) are sealed containers that protect the sand from exposure to wind and prevent dust generation.
4. Operator will post an access road speed limit not to exceed 20 miles per hour to minimize fugitive dust emissions from vehicle traffic traveling on the access road.
5. Operator will perform regular inspections and road maintenance to ensure the integrity of the access road and associated features is maintained throughout the life of this project. Maintenance consists of re-compacting the road base/recycled asphalt mix on an as-needed basis.

1/24/2024 | 1. Sediment Control Log: Sediment control logs will be installed around all sides of the topsoil stockpile at any time it is not being actively accessed. The sediment control logs will be made of excelsior, straw, coconut fibers, or wood chips, and will be anchored to the ground with wooden stakes. The sediment control logs will function to reduce water flow velocities in order to mitigate rill erosion formation. Additionally, the erosion control logs will capture sediment in order to mitigate topsoil loss from the stockpile.
2. Stockpile Management: Topsoil will be stockpiled along the southern edge of the proposed pad. In order to mitigate topsoil loss and migration of soil offsite, the stockpile will undergo surface roughening, seeding, and mulching.
3. Surface Roughening: Once topsoil segregation and stockpiling are complete, the stockpile surface will undergo surface roughening. A tracked vehicle will drive over the surface in order to imprint horizontal ridges to encourage sediment entrapment, improve infiltration, and reduce runoff velocity.
4. • Seeding: Once topsoil segregation, stockpiling, and surface roughening are complete, the stockpile will be seeded to mitigate erosion. Establishing vegetative cover will help to stabilize the soil, reduce wind and water erosion, minimize rill erosion, and reduce overall surface runoff. The stockpile will be regularly monitored for noxious weed growth. Re-seeding will occur as necessary, over the course of active construction in order to achieve wide spread uniform
vegetative cover.
5. Mulching: Post seeding, a layer of straw or hay mulch will be installed via crimping along the stockpile, in order to promote seed germination and further stabilization of the soil. Mulching helps to mitigate the impacts of rainfall and increase soil moisture retention. Mulching will be monitored and re-applied as necessary, until vegetative growth is established.
6. Use of freshwater to minimize the generation and transportation of dust. |
