Phantom Ranch Percolation Evaporation Area – Cyclic Repairs 2025 Lou Rogers, GRCA Civil Eng., March 10th, 2025

Background and Existing Condition The Phantom Ranch percolation/evaporation area (perc area) was constructed in 2022/2023 as part of the PMIS project #229035, Rehabilitate Phantom Ranch Wastewater [Treatment]

Plant (PR WWTP) Tertiary Treatment, Equalization Tank, and Headworks. The project was reviewed by the Park, PEPC #106345, and is closed complete. The perc area was constructed to replace the failing PR WWTP effluent discharge irrigation bubbler system and was brought online in January 2024. The existing emergency effluent discharge overflow trench was rehabilitated in 2020/2021 and remains in service if needed.

The perc area functioned nominally until late March of 2024 when the effluent discharge started to pond in the perc area rather than infiltrate quickly into the native soil as the design predicted. Two reasons for the inhibited percolation were identified by the plant operators:

one, there was heavy unpredicted plant growth in the perc area and two, there appeared to be an organic biomass growing in the top 2” of the native soil.

Ponding in the perc area also caused effluent ‘blowouts’ through the sidewalls.

The PR WWTP operators have been removing the plant growth and roto-tilling the native soil to increase the percolation rate and prevent ponding, plant growth, and blowouts. It is their belief that these actions appear sufficient in the low flow season but will not function as intended in the high flow season.

Project Description This project proposes the following cyclic repairs to address the inhibited infiltration, excessive plant growth, and the sidewall blowouts: installation of HDPE liner on the inside of the perimeter walls, remove 2” of the top native soil, place 3” of #57 gravel and bed effluent discharge piping in the 3” of gravel, install weed barrier, and place 1” of #57 gravel on top of the weed barrier. Please note, none of the proposed repairs changes the existing footprint or affect the look of the perc area. All work will be done inside the perc area fence. Work will be done on one cell at a time to allow the PR WWTP to continue operating.

Work Plan

* Work to be done on one cell at a time. This allows the PR WWTP to remain operational.

1) Remove bird netting

2) Remove section of exterior wall to allow small excavator to enter perc area cell.

3) Remove effluent distribution piping within the cell.

4) Excavate interior of cell perimeter wall to facilitate the installation of the HDPE perimeter liner (see slides 4 & 5 for liner details and slide #7 for liner material cut sheet).

Install liner and backfill.

5) Remove top 2” of native soil throughout perc cell infiltrative area and distribute along the interior perimeter of the perc area wall at 1:1 slope (see slides 4 & 5 for details)

6) Place 3” of #57 ( see slide #6 for gravel cut sheet) gravel over entire infiltrative area and bed effluent distribution piping in the 3” of gravel.

7) Place weed barrier fabric (see slide 3 for plan view and slide # 8 for material cut sheet) over 3” of gravel and cover with 1” of #57 concrete gravel over weed barrier.

8) Reinstall fence section that was removed in step 2.

9) Install bird netting

Revised June 12, 2025

Background:

1. EXISTING CONDITIONS

The Phantom Ranch percolation/evaporation area (perc area) was constructed in 2022/2023 as part of the project PMIS

229035, Rehabilitate Phantom Ranch Wastewater [Treatment] Plant (PR WWTP) Tertiary Treatment, Equalization Tank, and Headworks. The perc area was constructed to replace the failing PR WWTP effluent discharge to the Phantom Ranch

Delta irrigation bubbler system and was brought online in January 2024. The existing emergency effluent discharge overflow trench was rehabilitated in 2020/2021 and remains in service if needed.

The perc area functioned nominally until late March of 2024 when the effluent discharge started to pond in the perc area rather than infiltrate quickly into the native soil as the design predicted. Two reasons for the inhibited percolation were identified by the plant operators, one, there was heavy unpredicted plant growth in the perc area and two, there appeared to be an organic biomass growing to a depth of 2 inches in the native soil. Another result of the ponding of the effluent is effluent leakage out the sidewall of the perc area.

2. PROJECT DESCRIPTION

The Phantom Ranch Percolation/Evaporation Area, designed to infiltrate effluent discharge from the Phantom Ranch

Wastewater Treatment Plant (PR WWTP) quickly into the native soil, is not infiltrating properly and the effluent is ponding in the infiltration area.

To stop the ponding, increase the infiltration rate, and prevent effluent leakage through the sidewalls, this project proposes to:

1) Work to be done on one percolation area cell at a time. This will allow the PR WWTP to continue to operate.

2) Remove bird netting from current cell being worked on.

3) Remove one section of sidewall planks to allow small excavator access.

4) Excavate the interior sidewall perimeter of percolation area cell and install HDPE liner (see graphic slide #4, #5, & #7) and backfill.

5) Remove the top 2 inches of native soil from the cell being worked on. The removed native soil will be placed against the interior of the sidewall perimeter at 1:1 slope (see graphic slide #5). Install 6” metal landscape edging to retain slope of native soil placed at perimeter.

6) Place 3 inches of #57 gravel over surface of the percolation area using the previously installed landscape edging to define the limit of the gravel. Bed the effluent distribution piping in the 3 inches of gravel (see graphic slide #4

& #6).

7) Cover the 3 inches of gravel with weed barrier cloth (see graphic slide #8).

8) Place another 1 inch of gravel over weed barrier cloth. This will hold the weed cloth in place and prevent solar degradation.

9) Reinstall sidewall planks and bird netting. Repeat process on adjacent percolation area cell.

1.8 INNER CANYON BUNKHOUSE CODE OF CONDUCT

Work

The primary purpose for Inner Canyon bunkhouse use is to facilitate the completion of NPS work projects. These are

NOT party trips and events. We expect all workers and participants to be fully engaged and actively participate in all required duties for the duration of each trip. This includes shared activities: loading and unloading, cooking, doing dishes, keeping facilities clean, and completing final facility cleaning prior to departure.

Cooperation

Bunkhouse users often consist of employees from different divisions, NPS contractors, and volunteers. Rangers are expected to walk through the bunkhouse to check fire and safety equipment, look for emergent issues (broken pipes, running water, fire hazards, etc.) and check security. Establishing good working relationships is essential in shared https://www.nps.gov/grca/planyourvisit/backcountry-regs.htm https://www.nps.gov/grca/planyourvisit/backcountry-regs.htm

GRCA PMIS #327717 GENERAL REQUIREMENTS Page 7 quarters and requires full cooperation from everyone. Do your part to keep the bunkhouse clean. People may be working difference work schedules, so maintaining quiet hours and respect for the sleep of others is mandatory!

Quiet Hours

There are park visitors camping nearby and other residents in close proximity. At these locations, voices and noise carries and echoes, and we do not want to impact the experience of others. Many campers are exhausted and go to sleep at dark.

Quiet hours must be observed at these facilities from 8pm to 6am. However, noise can be unreasonable at any time of day, when other people are disturbed through inconsiderate or reckless behavior. If there is any non-adherence to these rules, you may be contacted by a Law Enforcement Ranger.

Professionalism, Rules, Alcohol and Drug Policy

NPS rules and regulations will be adhered to at all times. The use of alcohol in the Inner Canyon Bunkhouses, campgrounds and overflow areas is prohibited during or after work hours. Likewise, transport of alcohol by NPS on-duty staff or livestock is prohibited. Illegal drugs are against the law and will not be tolerated. Federal drug laws apply. We expect everyone to be professionals at all times.

Noncompliance with rules or regulations may result in the offender being expelled from temporary backcountry quarters and/or revocation of privileges to use bunkhouses by the offending program/division.

Dark Skies

Grand Canyon National Park is conserving our Dark Skies. Please do your part by closing the blinds on all bunkhouse windows after dark.

Rodents

All of the Inner Canyon Bunkhouses are prone to mouse infestations. Please keep the door closed except when walking in or out of the bunkhouse. Maintain good housekeeping measures…sweep floors and wipe counters after each and every meal preparation. Store food properly (rodent proof containers) when not in use (no leftover sandwiches and trail mix in your backpack on the floor overnight, etc.) If you see mice (or mouse sign) in the bunkhouse, please follow the Integrated

Pest Management notification procedure.

Positive Attitude

Maintain a positive attitude, be flexible, patient, and open to learning from others. The way you interact with others and with the group as a whole has an impact on the work and the reputation of your particular crew, so please be positive and professional.

f. Ensure no standing water on tarps or other construction surfaces as this may be a breeding ground for mosquitoes.

5. Archaeological Resources: Archaeological resources are physical evidence of past human activity, including evidence of the effects of that activity on the environment. Archaeological resources are found above and below the ground and underwater. The Contractor, or designee, will observe all ground-disturbing activities in archaeological sensitive areas. If the Contractor discovers resources, the

Contractor shall stop work or relocate to a non-sensitive area and notify the Contracting Officer immediately. The Park may also have an Archaeological Monitor at the jobsite who is authorized to stop work upon discovery of archaeological resources. Archaeological resources typically found in the park or at the project site will be discussed further at the preconstruction meeting.

6. Soundscape / Noise: The Contractor shall minimize noise levels at the project site to protect the soundscape of the park. Perform noise-producing work in less sensitive hours of the day or week or as directed by the Contracting Officer.

The following sections are mitigations copied directly from the Letter of Compliance Completion for PEPC project

#112986 and are specific to this project.

Cultural Resources

• Although there is no surface evidence of archaeological resources, clearance to proceed is recommended with the condition that if concealed archeological resources are encountered during project activities, all necessary steps will be taken to protect them, and the Park Cultural Resources Manager will be notified immediately.

• Areas selected for staging equipment and materials are expected to be located in existing disturbed areas where there is no potential for archaeological resource disturbance. Contact the park's Cultural Resource Program Manager before creating/utilizing any staging areas not previously addressed or reviewed for this project.

• Fence type: To avoid a potential "adverse effect" a Natina steel chain link fencing and posts (providing weathering steel look) at the minimum height required by ADEQ is recommended for use at Hermits Rest and Yaki Point.

Human Health and Safety

• Contractor to submit a site-specific safety plan to PM/COR. PM/COR will send safety plan to the Park Safety Officer, Christina Ryan-Miller (christina_ryan-mi11er@nps.gov) prior to commencement of work. Safety plan shall demonstrate compliance with OSHA and other applicable safety laws. It shall include an emergency safety plan and shall list contractor points of contact.

Park Operations and Management

• Contractor will alert the PM/COR who will then contact commercial services Park representatives, Victoria St.

Clair (victoria stclair@nps.gov) or Laurie Dyer (laurie dyer@nps.gov) should there be any service interruptions affecting concessioners.

GRCA PMIS #327717 GENERAL REQUIREMENTS Page 11

Soils, Topography, Geology

• Although there is no surface evidence of paleontological resources, clearance to proceed is recommended with the condition that if concealed paleontological resources are encountered during project activities, all necessary steps will be taken to protect them. PM/COR will contact Science Resource Management, Mark Nebel and/or Anne Miller (Geosciences program staff) when notified by contractor that paleontological resources have been encountered.

Vegetation

• Vegetation material removed from Phantom Ranch during the project that is unusable for revegetation efforts shall be disposed in the Colorado River by throwing it off the Silver Bridge. Face upstream and look for boats, do not throw when boats are in-view upstream of the bridge. Wait until any boats have passed the bridge downstream by at least 1/4 mile. NPS staff shall work with the project manager to determine the appropriate location.

• Vegetation removal, especially for the Phantom Ranch project area, will be minimized to the greatest extent possible while allowing for construction to proceed. If needed, revegetation of native plants will occur.

• No other surface-disturbing work or vegetative clearing shall occur without written permission from an authorized representative of the National Park Service.

• Upon project completion, the vegetation program shall survey and monitor the project area for invasive plants and respond accordingly to eliminate any invasive species.

• Pruning necessary for the project, and for any future periodic maintenance in the area, will adhere to the park's pruning guidelines with the goal of retaining health and integrity of trees and shrubs treated. Damage to trees or roots in or adjacent to project areas during construction will be avoided as much as possible, if avoidance is not possible, root pruning guidelines will be followed. The pruning guidelines are available from Vegetation Program Management staff.

• Equipment and supplies should be staged and stored in already disturbed areas on site and should not create any new impacts to vegetation resources.

Wilderness

• Helicopter flights over areas of proposed wilderness would degrade opportunities to experience solitude.

• To minimize flights over areas of proposed wilderness: 1) sling loads will be arranged so as to minimize the number of flights required to complete all transportation necessary, and 2) materials, tools, equipment, etc. will be staged at the helibase so that they may be transported to the worksite on other scheduled flights to the extent possible.

Wildlife

• Wildlife Department personnel shall be notified/consulted when any wildlife must be disturbed or handled. They will be available to assist with moving/relocating wildlife, when necessary, and/or to make recommendations for relocating any disturbed animals.

• For any projects involving trenching or digging holes, provisions (generally in the form of ramps with a slope< 45°) must be made every 20-50' to allow for the escape of animals that may fall into these recesses, and/or they must be covered in such a way as to prevent animals (vertebrates) from falling in them.

• If condors visit a project site, project activities will cease until the condors leave on their own or until permitted personnel use approved techniques that result in condors leaving the area.
