Churchill County, Nevada

To: ALL OFFERORS

This addendum is issued to modify/clarify the following:

Concerning the 5 ½” OD Flush Joint, Epoxy Coating (J55/K55):

1. What type of epoxy is required?

Answer: We are not requiring a specific type of epoxy coating, only that it is an environmentally friendly material that will limit corrosion and extend the life of the well.

In the past we've used epoxy coatings such as Tuboscope TK-69. Comparable products may be proposed by the subcontractor.

2. What is the desired weight per foot of casing?

Answer: There is no weight/foot specification for the well casing.

3. Is there any required perforation pattern?

Answer: A typical slot pattern is 3-inch long manufactured slots with 0.078-inch slot openings on 6-inch centers and 6 rows of slots staggered 60 degrees apart. See pictures below.

If you have any questions, please call the undersigned at (970) 248-6684 or email at Contracts@lm.doe.gov.

Sincerely, Julie M. Hendricks Contract Administrator
