About this file
This document is an amendment to a Request for Lease Proposals (RLP) issued by the USDA Forest Service. The amendment updates the requirements for retardant loading pads, which must be constructed with sulfate-erosion resistant concrete to withstand damage from aircraft operations and retardant spills/washdowns. The pads must have a manifold system to deliver retardant from the tank farm, and be designed with trenches or grading to contain spills and washdown water. A minimum of four pads are required to support two Very Large Air Tankers (VLATs) and two Large Air Tankers (LATs), with optional features including electrical outlets and plumbing for washdown. The related federal contract opportunity is Solicitation No. 127EAB24R1204-3, issued by the USDA Forest Service.

RLP AMENDMENT NO. 3
TO RLP NO. 127EAB24R1204
P a g e | 1 of 1
Request for Lease Proposals No. 127EAB24R1204 is amended as follows:
Exhibit C1, Agency’s Specific Requirements, Additional Requirements, Pads/Pits section, is deleted and replaced as follows:
Pads/Pits
Loading pads are often referred to as “pits.” A pad or pit (also called gate position) is a specific parking place for an aircraft to load/unload, refuel, washdown, tiedown, or do maintenance. The standard large airtanker loading pad is 100’ X 100’. These pads are subject to spillage, leakage, and after-drop dripping. Retardants that contain ammonium sulfate will erode most concretes and guar gum will spall (flake, chip, or fragment) asphalt surfaces. Retardant loading pads should be constructed with type-15 (sulfate erosion resistant) concrete with appropriate air entrainment to prevent damage from winter freezing. The structural design should conform to the FAA design method for rigid pavement. This will typically require that the concrete used by aircraft be specified by tensile strength requirements.
Each pad requires a retardant delivery manifold provided by the Government contractor consisting of two (2) approximate 6” pipes capable of delivering retardant from the Tank Farm to the Pad. Piping that carries retardant should not be buried but can either be placed above ground OR in a concrete trench covered with steel grating. This allows the pipe to be removed easily for repair or replacement and also provides some protection from direct sunlight. These trenches should be designed to be a part of the containment and disposal system for spills and washdown water. The Lessor shall provide the following:
• Minimum of four pads needed for two VLATs and two LATs.
The Lessor may provide the following options:
• One quadraplex 110V electrical outlet per pad for powering portable A/C units.
• Each pad shall be plumbed for 1” to 1½“ hose with approximately 200 GPM flow rate for wash down.
• Light fixed wing aircraft do not require retardant manifolds but require one quadraplex electrical outlet for powering portable A/C units and plumbing for 1” to 1½“ hose with approximately 200 GPM flow rate for wash down.
• Pads shall be designed with trenches or grading to provide containment for wash down or spillage.
