1/12/2021 | Operator will have an MLVT Design Package, certified and sealed by a licensed professional engineer, which is on file in their office and available upon request. The site shall be prepared in accordance with the specifications of the design package prior to tank installation; including ensuring that proper compaction requirements have been met. The MLVT will be at least 75 feet from a wellhead, fired vessel, heater-treater, or a compressor with a rating of 200 horsepower or more. It will be placed at least 50 feet from a separator, well test unit, or other non-fired equipment. All liner seams will be welded and tested in accordance with applicable ASTM international standards. Operator will be present during initial filling of the MLVT and the contractor will supervise and inspect the MLVT for leaks during filling. Operator will comply with the testing and re-inspection requirements and associated written standard operating procedures (SOP) listed on the design package. Signs will be posted on the MLVT indicating that the contents are freshwater. The MLVT will be operated with a minimum of 1 foot of freeboard at all times. Access to the MLVT will be limited to operational personnel and authorized regulatory agency personnel. Operator or contractor will conduct daily visual inspections of the exterior wall and surrounding area for integrity deficiencies. Operator will have a contingency plan/emergency response plan associated with the MLVT and it is on file at their office. A fabric reinforced liner will be utilized. In the event that a tank breach were to occur, the fabric reinforced liner will prevent a “zippering” failure from occurring. The liner will meet the specifications per the design package.

4/5/2022 | • Most work operations will take place 7-days a week & 24-hour a day. Care will be taken to keep lighting levels at
the specified levels on the lighting plans while providing safe, well-lit working areas during night-time and other
low-light conditions. Care will also be taken to prevent unintended light from leaving the site and becoming a
hazard or nuisance to the public or surrounding wildlife habitat.
• During the Pad Construction Operations, no night-time work is anticipated. Daylight work will be performed during
this work operation.
• All lighting shall conform to Federal, State, and Industry recognized standards for both on-site workplace safety
and off-site public protection (OSHA, FAA, COGCC, IESNA, and ANSI). No direct light, except those governed
by FAA standards, shall shine beyond the boundaries of the WPS, especially onto public roads, adjacent
properties, and/or high priority habitats. All lighting shall conform with all COGCC, county, municipal, and any
applicable governing body’s standards.
• Temporary lighting will be 3-head LED flood lights on mobile 25-foot telescoping towers (BUG Rating is B3-U3-
G5). All lighting will be capable of adjustment and will be directed inward and between 45-65° downward towards
working areas on the WPS. No light should shine above the horizontal plane passing through the center point of
the light source. Lights will be shielded with a photometric diffusion fabric or membrane tint to prevent direct or
reflected direct light from leaving the site.
• Permanent lighting will be pole and stanchion mounted floodlights (BUG Rating is B3-U0-B3). All lighting will be
capable of adjustment and be directed downward.
• Wall panels (e.g., visual/sound walls) during drilling and completion operations will be placed along the south and
west sides of the drilling pad and will be removed for production operations. For workplace safety, no direct or
reflected direct light shall shine towards the entrance of the WPS.
• Watch for and remove glare and reflection points during all work operations of the project from temporary or
permanent structures, temporary lighting, vehicles, construction equipment, and clothing/PPE.
• Any lighting damaged and/or improperly directed or angled will be promptly fixed and/or corrected to conform to
the lighting plan.
• Equipment shall be operated and/or orientated and/or shielded in such a manner that lights permanently affixed
to equipment do not shine above the horizontal plane passing through the center point of the light source or shine
beyond the boundary of the WPS.
• For all work operations, once temporary lighting is in place, a lighting self-audit of the site will be performed to
ensure that no unintended light will leave the site and become a hazard or a nuisance.
• For any change to the lighting during any work operations, a lighting self-audit of the site will be performed to
ensure that no unintended light will leave the site and become a hazard or a nuisance.
• For non-working or shut-down days where no personnel are on-site or in working areas, non-essential temporary
lighting will be turned off. If no personnel are on-site and essential temporary lighting is needed, the essential
temporary lighting will be inspected every 24 hours.
• All redundant, unused, or not-needed lights will be turned off.
• Any additional light units used to address workplace safety concerns that are not shown on the lighting
photometric plans will be verified by a lighting engineer to ensure that the modified lighting will remain within the
required lighting standards stated in this report. |
