GENERAL INFORMATION AND REQUIREMENTS

PART 1 - GENERAL

1.01 SUMMARY:

A. Background: Mavencamp Well is an existing well that was originally dug and developed in 2008, but a pump was not installed. The well has remained idle since that time. The total depth of the well is 375 feet.

1. The following background information is included with these Specifications:

a. A copy of the original Montana Well Log Report GWIC Id: 250571 dated 10/28/2008.

b. A current photo of the existing wellhead.

B. Scope of Work:

1. Base Bid consists of the following work:

a. Yield test existing well to verify its viability and to ascertain that historical yield data remains accurate as per the original Montana Well Log Report. Furnish expertise, materials, equipment, and labor to perform preliminary yield testing, well development, final yield testing, and capping of the well.

2. Additives Bid consists of the following work contingent on results of yield testing:

a. If yield test results prove successful, meeting the production rate requirement of 10 gallons per minute, then furnish materials, equipment, and labor to install a submersible pump, pitless adapter, solar-powered electric generation system, and livestock exclosure for the existing well site. Work shall include connection from pitless adaptor to existing underground water line and installation of curb stops. Work shall also include all related appurtenances necessary to ensure a fully functioning well system.

b. If yield testing results do not meet minimum production requirements, then the

Government reserves the right to evaluate and consider alternative courses of action.

The Government and the Contractor will engage in discussions to determine the appropriate next steps. These steps may include, but are not limited to, modifications to the existing Contract or the development of a new path forward, which will be mutually agreed upon. Any adjustments or modifications to the Contract will be formalized in writing and executed through a Contract modification.

i. If it is determined that no further action can be taken under the current scope, the Government may, at its discretion, de-obligate the Additives Bid Items in the Bid Schedule and may execute a termination for convenience of the Contract.

Should further work be required, it may be pursued under a separate Contracting vehicle or under a new agreement that better aligns with the project needs.

C. Location: This well is in Phillips County, Montana, located approximately 50 miles northeast of

Malta, Montana (and approximately 17 miles northeast of Whitewater, Montana) at Section 01, T36N, R32E SW1/4 SW1/4 SW1/4. Coordinates: Latitude N 48.901500, Longitude W 107.490917.

B. Minimum required yield shall equal 10 gallons per minute (gpm).

2.01 EQUIPMENT

A. Well Testing and Developing Equipment: Equipment must, at a minimum, be able to test and develop the well at 1-1/2 times the minimum required yield at 1-1/2 times the maximum depth listed.

The following equipment shall be on site:

1. Final Yield Pump Testing Equipment: Pump shall be capable of pumping 1-1/2 times the minimum required yield. Pumping unit shall be equipped with a hose and valve to regulate the flow for the purpose of establishing the maximum yield at various depths. Furnish generator capable of operating the pump, drop pipe and outlet pipe with a flow meter.

2. Provide temporary lines for safe discharge of test water away from work area as approved by Contracting Officer.

B. Well Cap: Use existing well cap.

3.01 DISINFECTION:

A. General: After the well has been fully developed and results show that the well can produce the required minimum yield:

1. Clean the hole thoroughly of foreign substances and swab the casing pipe, using alkalis if necessary to remove oil, grease, or joint dope. The well shall then be disinfected with a chlorinated compound. The disinfection agent shall be left in the well for a period of at least 12 hours. After a 12-hour – or longer – contact period, the well is to be pumped to clear it of the disinfection agent.

B. Chlorine Solution: Prepare and apply chlorine solutions according to the following table:

Chlorine Compound Required to Dose 100 Feet of Water-Filled Well at 100 pp

Casing Volume Per 5.25% Purex or Diameter 100 Feet Chlorox (inches) (gallons) (liquid measure)

b. Pumping water level

c. Static water level

d. Water recovery rate and level

e. Time of starting and ending each test cycle,

2. Provide for continuous constant rate pumping at 1.5 times the minimum yield required. Pump for 8 hours. The test may be terminated if stabilized drawdown occurs for two hours during the test. If the design pumping rate is 35 gpm or greater, the minimum stabilized drawdown period must be at least eight hours.

3. Divert and measure the flow of water through a mechanical flow metering system capable of measuring accurately to within 1/4 gallon/minute. Complete pump test results shall be provided in writing to the Contracting Officer as soon as they are available.

4. Protect the well during the construction period to prevent tampering or seepage of contaminated water, petroleum products, or other contaminants into the well from the ground surface.
