Clear Water Rinse System (A) / Rinse Cart Filtration & Filling System (B)

Statement of Objective (SOO)

REF: FA252125QB040

SYNOPSIS A: Replace the existing aircraft Clear Water Rinse System (CWRS) which is both inefficient and constructed using equipment that does not meet the standard required for C-130 or H-60 Clear Water Rinse and wash practices. The existing system was designed for helicopters and uses city water, which is out of the technical order standards, low water volume, and does not rinse an entire C-130. New equipment will meet or exceed the standards and requirements set forth below at a minimum.

SYNOPSIS B: Provide a new Water Pretreatment System that will efficiently provide rinse carts with the ability to consistently fill with the correct water quality regardless of varying base water supply parameters. Base water quality varies widely on the installation and often fails to meet water quality standards set forth in TO 1-1-691 standards for aircraft cleaning. Base water that does not meet or exceed water quality standards can decrease effectiveness and introduce new corrosion causing contaminants to airframes and engines such as Iron, Chlorine, and Salts commonly found in potable water sources.

A. The installation of the CWRS will include the following:

1. General:

1.1. Contractor to install a new water delivery system. Larger delivery pumps improving ability to target rinse operation for C-130 and H-60. Supply a new pump with sufficient water tank capacity to maintain flow up to 2200 GPM.

1.1.1. Complete installation (all requirements) performed and managed by contractor with inspection and acceptance performed by the government.

1.1.2. Weekly team meetings and status updates at a minimum will be conducted during contracted period of performance.

1.1.3. Installation drawings and required permits (placement, electrical, plumbing, etc.)

will be provided as requested with final drawing deliverables.

1.2. Water lines and power lines will be run to the new clear water rinse system from a new system ISO container, installed, plumbed, trenched, and connected for full operation by contractor.

1.3. Site survey will determine location for equipment which is assumed to be placed upon a concrete surface to support at least two ISO containers (L 40ft x W9ft) for an approximate pad area of 60ft x 24ft.

1.4. Work is within an area of high concentrations of PFAS contamination in soil and groundwater and the area of the project is undergoing an active Remedial Investigation (soil and groundwater sampling).

1.4.1. All ground disturbance must be coordinated with the 45th Civil Engineering Squadron

(CES).

1.4.2. All soils must be retained onsite and returned to the depths at which they were excavated or coordinated for proper offsite disposal.

1.4.3. If groundwater contact is anticipated, additional coordination will be required. If dewatering, a dewatering management plan must be submitted to for approval.

1.4.4. The project proponent should also consult with their health and safety personnel regarding the proper selection of PPE for working in a contaminated site. Any backfill brought onsite should be tested or analysis results should be obtained from the borrow pit and provided. Sampling is requested to prevent any contamination being brought onsite and to follow regulatory requirements.

1.5. All coordination for permits is completed through 45th CES office prior to installation.

1.6. Dewatering/Potable: If dewatering is anticipated a dewatering plan must be submitted to for review.

1.7. Hazardous Materials: Contractor needs to obtain approval for all hazardous materials brought onto installation via submission of material names and SDS documentation.

1.8. Natural Resource Exterior Lighting: Any excavations outside of concrete/impervious will require a wildlife survey (burrows, etc.) at least one week prior to digging commencement.

1.9. Environmental Restoration: The project is adjacent to an area of groundwater contamination. If digging to the groundwater table, additional coordination is needed with IRP to ensure compliance with land use controls and to ensure worker protection and safety. Any dewatering activities require the submission of a dewatering management plan prior to any dewatering efforts.

1.10. If lighting will be added or construction lighting needed it must follow Space Wing Instruction (SWI): 45 SWI 32-7001, Exterior Lighting Management, (limited wavelength true amber unless a variance is approved).

2. Installation:

2.1. The new system ISO containers will be delivered and put into place on the pre-determined pad area by contractor.

2.2. All conduit and plumbing lines will be connected to a pre-determined main water, sanitary drain, and electrical connection co-located to the new system.

2.2.1. No storm water management areas should be proposed within any airfield imaginary surface.

2.2.2. Connection to sanitary drain estimated at:

C130J = 3,600 Gallons each 2-minute cycle; Avg cycles 377 equates to Estimated 1,357,220 Gallons/Year

HH60 = 3,600 Gallons each 2-minute cycle; Avg cycles 671 equates to Estimated 2,415,600 Gallons/Year

Total estimated annual Birdbath storm water discharge: 3,772,820 gallons

2.2.3. All required permitting completed and filled as required in a timely manner as to not delay installation progress.

2.3. Include 316 Stainless Steel (SS) piping and Nozzles.

2.3.1. All fittings and hardware must endure extreme salt, heat and humidity conditions used in over carriage and undercarriage nozzles.

2.3.2. Nozzle pits shall require lids to extend life of system and prevent potential performance degradation (due to animals, clogging, grass clippings, etc.).

2.4. Nozzles will provide the required spray area for 360-degree C130 and H-60 coverage.

2.4.1. Pressure and nozzle selection must account for the wind patterns at Patrick SFB.

2.5. Pressure/spray adjustments/patterns will not damage avionic systems (i.e. nose turret sensors, fuselage sensors, randoms, etc.).

2.6. Ability for manual or automated adjustability will account for seasonal change in wind direction. To accomplish, contractor will provide the required piping size and quantity to allow for the desired flow.

2.7. All taxiway trenches and pits will be grated with aircraft rated Ductile Iron.

2.7.1. New water cannons will be positioned in the grass area adjacent to the rinse taxi area buried in the ground requiring a concrete or stainless-steel box pit at grade not to exceed 3 inches above grade level.

2.7.2. All above ground obstructions are frangible.
