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 by the addition of liquid nutrients 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 INTENT

Dworshak Project requires supply and delivery of liquid 32-0-0 Urea Ammonium Nitrate, to include the provision of storage tank 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 total quantity of the base contract shall not exceed 43,600 gallons; however, the

Government reserves the right to increase or decrease the fertilizer quantities during the course of the contract at the awarded price per gallon.

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 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 that is to be applied. The formulation for this fertilizer should have the lowest levels of these metals and other contaminants as possible.

3.2.2 Not less than one week prior to the first delivery of fertilizer, the Contractor shall provide the Contracting

Officer and Project Point of Contact (POC) 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.

3.2.3 Laboratory analysis shall comply with analytical and sampling test methods described in the US

Environmental Protection Agency’s publication “Test Methods for Evaluating Solid Waste, Physical/Chemical

Methods", SW-846. Specific tests and maximum permitted levels of metals are described in Attachment 1 of this specification. Only fertilizer meeting these ppm standards will be accepted. Alternate generally accepted test methods may be utilized, 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 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 previous tested and accepted delivery.

4.0 FERTILIZER STORAGE

4.1 Tank Specification

The Contractor shall provide one or more storage tanks to hold delivered fertilizer at Dworshak Project. Minimum total capacity shall be 9,000–10,000 (10,000 maximum). If more than one tank is supplied, the set up 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.

4.2 Secondary Containment

The Government will provide secondary containment for the storage tanks. 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. See photos below, which show the secondary containment area open for loading tanks and with 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

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.

6.2 Storage Tanks and Pumping System

The storage tank(s) and pumping system shall be delivered between April 17 and April 25, 2017, inclusive.

6.3 Fertilizer

6.3.1 Program Requirements. The Government has a rigid requirement to apply fertilizer to Dworshak

Reservoir on a weekly basis. The first delivery of fertilizer shall be made after the delivery of the tank(s) and not later than May 2, 2017. Subsequent deliveries shall be scheduled sufficient to ensure the Government maintains a minimum one week of fertilizer on hand. The Contractor shall pump the fertilizer from the transport tank into the Contractor-supplied storage tank for the Government’s use.

6.3.2 Program Variables. Attachment 4 provides a representative sample schedule for information only. The actual amount of fertilizer applied to the Reservoir during the 2017 season will vary based on prescription and

Reservoir conditions, as well as the Contractor’s delivery capacity.

6.3.3 Coordination. This requirement is carefully tracked and managed by Project personnel. Requests for delivery will be made by the Project POC based on actual program requirements. Historically, 8–10 deliveries are requested during the May 1–September 30 season. The Government will provide the Contractor at least one week notice of delivery requirement and, except for the final load of the season, will request full-capacity loads.

The Contractor shall coordinate with the Project POC to ensure delivery within the required timeframe and availability of Project personnel for access to the storage site.

6.3.4 Delivery Days/Times. Deliveries shall normally only be made during normal Project business hours, Monday–Thursday between 7:30AM and 4:00PM.
