11/6/2019 | Storm Water/Erosion Control:
a. Temporary controls may be used in conjunction with permanent controls around draws, or at locations where erosion hazards are high. BMPS will be used as designed for the special areas to reduce any migration of soils onto and off of site. Energy dissipating controls will be installed at culverts and other areas that have the potential for increasing the concentration of water volume and velocity that could increase erosion.
b. Drainage dips, ditch relief culverts, and water wings, when used, will be spaced and placed to divert water flow off the graded rights-of-wat onto well-vegetated areas with low erosion potential.
c. Non-Structural practices spoils excavated will be stored in a manner to prevent displacement. Wattles or other adequate erosion control practices will be implemented around the spoils to minimize erosion. Interim Stabilization controls will be used throughout construction and after construction until a permanent vegetative cover is in place. All Best Management Practices employed will be designed to withstand a twenty-five(25) year weather event. The type and frequency of BMPs used will be determined by slope, topography, soil types and vegetation and potential runoff from adjacent areas that could affect the overall performance of the controls. Diversion ditches will be designated to discharge runoff into well vegetated areas or locations with a low erosion potential. Water bars or wings, when used, will be spaced and placed to divert water flow off disturbed areas and onto well-vegetated areas. Temporarily controls may be used in conjunction with permanent controls around spoil piles, draws, or at locations where erosion hazards are high. BMPs will be used as designed for the specific areas to reduce any migration of soils off site. Energy dissipating controls will be installed at culverts and other areas that have the potential for increasing the concentration of water volume and velocity that can increase erosion.
d. Rat and mouse holed will be backfilled on release of the completion rig from the location. Backfilling, leveling and rec-contouring are planned as soon as reasonable possible following drilling and completion operations. Fill slopes will be smoothed and reshaped to near pre-disturbed conditions to match the native contour. Fill slopes will be restored to cuts and blended or reshaped into large natural berms that provided visual and storm water benefits. It damages to reclaimed areas occurs as a result of well operations and maintenance, including work over operations, affected areas will be reclaimed again following operations. |

11/6/2019 | The existing well pad has a compacted earthen perimeter berm and raised pad entrance. The access roads to the location run along the southern and western edges of the well pad. There are two other access roads located to the north and northeast of the well pad, one with a borrow ditch and one with berms. No storage tanks are required for this location since all produced water will be piped in through existing onsite and offsite pipelines. The only equipment associated with the proposed injection well is an automated control skid. The existing BMPs will be monitored daily and maintained to ensure site containment in the event of a potential release. |

11/6/2019 | Chevron has the ability to monitor real time pressure and injection rates through the field SCADA system on the control skid. Additionally, an alarm will be added to the tubing pressure transmitter on the control skid to notify field operations personnel should tubing pressure exceed the maximum allowable surface injection pressure to ensure a quick field response. |
