SPECIFICATION

DWORSHAK LIQUID FERTILIZER

1.0 BACKGROUND

The U.S. Army Corps of Engineers, Walla Walla District, Dworshak Project (Project) provides nutrient supplementation to Dworshak Reservoir to balance levels in the Reservoir and to enhance Reservoir productivity.

To accomplish this, Dworshak Project applies liquid fertilizer in a prescribed amount weekly during the months of May through September.

2.0 SCOPE

Dworshak Project requires supply and delivery of liquid 32-0-0 Urea Ammonium Nitrate, to include the provision of storage tank(s) with approximately 10,000 gallons capacity and pumping system for transferring fertilizer from storage tank to Government-owned mobile tanks. Deliveries of fertilizer will be as needed to operate the nutrient supplementation program. The maximum quantity is not expected to exceed 43,000 gallons; however, the Government reserves the right to increase quantity during the contract via a contract modification signed by the Contracting Officer.

3.0 FERTILIZER SPECIFICATION

3.1 Fertilizer Specification

The Contractor shall provide liquid urea ammonium nitrate (32-0-0) fertilizer. This fertilizer shall be standard industry formulation for this type of fertilizer. The fertilizer shall be in liquid form for application to aquatic lake ecosystems.

3.2 Initial Testing Requirement

3.2.1 The Offeror shall provide with their quote an independent laboratory analysis verifying the nutrient levels of the fertilizer (32-0-0) in percent of each nutrient and all trace metals in parts per million for the product being offered.

3.2.2 Of concern to the Government are the levels of arsenic, zinc, cadmium, and other trace metals or contaminants that may be contained in the liquid fertilizer that is to be applied. The formulation for this fertilizer should have the lowest levels of these metals and other contaminants as possible.

3.2.3 Laboratory analysis shall comply with analytical and sampling test methods described in the latest version of U.S. Environmental Protection Agency’s publication SW-846, “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods.” Specific tests and target maximum levels of metals are described in Attachment 1 of this specification. Generally accepted alternative test methods may be acceptable, as long as the required levels of accuracy are demonstrated and achieved.

3.3 Subsequent Testing Requirements

Additional laboratory reports are required, not less than one week prior to delivery for, each subsequent load of fertilizer requested, or, alternately, the Contractor may provide attestation that that the material being delivered is from the same unaltered source and pick up point as a previously tested and accepted product.

4.0 FERTILIZER STORAGE

4.1 Tank Specification

The Contractor shall provide one or more storage tanks to hold delivered fertilizer at Dworshak Project. The Offeror shall provide with their quote photos, cut sheets, and/or other appropriate documentation necessary for the Government to determine whether the storage tanks offered meet all requirements listed below.

4.1.1 Capacity. Total capacity shall be minimum 9,000 gallons and maximum 10,000.

4.1.2 Quantity. If more than one tank is supplied, the setup must be configured so that only one filling/dispensing location is required (separate dispensing on multiple tanks will not be accepted). Storage tanks shall meet State of Idaho standards for fertilizer storage.

4.1.3 Sight Gauge/Safety Valve. Tank(s) shall be equipped with a sight gauge with safety valve, for convenient and accurate visual tracking of product levels and to ensure minimal loss of product in case of a hose leak or break.

4.2 Secondary Containment

The Government will provide secondary containment for the storage tank(s). The dimensions of the available area within the containment area are 30 feet by 20 feet (2 feet high). The Contractor shall be responsible for repair or replacement of any damage to the containment area or liner during placing and/or removal of the Contractor-owned tanks. The photos below show the secondary containment area open for loading tank(s) and an example of tanks enclosed within.

5.0 FERTILIZER PUMPING SYSTEM

5.1 Mobile Tank Systems

The Government will utilize its own mobile tanks for temporary storage and application of the liquid fertilizer. One tank is a 4,000 gallon stainless steel tank with an 8-inch lid on the top of the tank. The other tank is a 300 gallon polyethylene tank with a 4-inch diameter opening on the top of the tank.

5.2 Pumping System

The Contractor shall provide a pump delivery system to transfer the fertilizer from the storage tank to the Government-owned mobile tanks. No electricity is available at the storage tank site. The delivery system shall have a 2-inch gas-driven pump, capable of pumping 1,500–2,000 gallons per hour, with 40 feet of 2-inch diameter delivery hose provided. The hose shall have industry standard cam-lock couplers, so the Government can extend the hose if necessary. The Contractor shall be responsible for maintenance, repair, and/or replacement of the Pumping System in the case of failure.

6.0 DELIVERY

6.1 Delivery Location and Scheduling

All items in this Contract shall be delivered to Dworshak Project, approximately five miles west of Orofino, Idaho, off Highway 7. This location is accessible for large tractor-trailers for delivering the fertilizer. Maps illustrating the fertilizer storage/delivery location are included in Attachments 2 and 3. Deliveries shall normally only be made during normal Project business hours, Monday–Thursday between 7:30 AM and 4:00 PM.

6.2 Storage Tanks and Pumping System

The storage tank(s) and pumping system shall be delivered between April 12 and April 19, 2021, inclusive, and the empty tanks shall be removed as early as practicable for the both the Government and Contractor after the end of the application season.

6.3 Fertilizer

6.3.1 General Requirements. The Government has a rigid requirement to apply fertilizer to Dworshak Reservoir on a weekly basis May 1 thru September 30 each year, and this requirement is carefully tracked and managed by Project personnel. All deliveries shall be coordinated with the Government POC.

6.3.2 Pumping. The Contractor’s delivery personnel shall pump the fertilizer from the transport tank into the Contractor-supplied storage tank for the Government’s use.

6.3.3 Initial Delivery. The first delivery of fertilizer shall be made after the delivery of the storage tank(s) and not later than May 1, 2021.
