Dear Mr. Holonich:
Enclosed are three copies of International Uranium (USA) Corporation's ("IUSA") Rock Sampling and Testing Program. IUSA committed to providing the details of this program. and implementing the program in our response to Question No. 18 of the NRC's July 17, 1998 request for information.
A copy of the Program is also being sent to the Center for Nuclear Waste Regulatory Analysis.
We would appreciate receiving any comments you may have on the Program. We will begin gathering samples within the next two weeks in order to meet the schedule committed to in our August 28 transmittal.
Very truly yours.,

Rock Sampling and Testing Program - White Mesa Mill The purpose of this Rock Sampling and Testing Program is to determine \Vhcther the sandstone rock stockpiled at the White Mesa Mill has the qualities to be utilizcJ as erosion protection material for the reclamation of the tailings ponds. The testing performed in this program will follow, as much as is practical. the guidelines for rod testing as presented in NUREG/CR 2642. (Long-Term Survivability of Riprap fr>r Armoring Uranium Mill Tailings and Covers: A Literature Revic\\ ).
Sampling Sampling will take place on each of three stockpiles of random fill (designated RF-2. RJ:_
3 and RF-6 on Exhibit A) that contain oversize rock which is planned to he used for rock annor on the reclaimed tailings cells. A total of four samples of the m ersizcd material will be taken from each stockpile. Samples will be taken from: I) material exposed at the base of one of the slopes. 2) material exposed at the top of a slope. 3) material from a backhoe pit excavated into the top of the pile to test unexposed rock and 4) material from a ramfom test pit which will be determined by the engineer at the time of the sampling.
Sample locations will he located on a site map and sample descriptions will recorded and maintained in the facility's records. A total of twelve samples from the three sto<.:kpiles will be submitted for durability testing Testing Samples will be packaged and shipped to a certified commercial testing laboratory for durability testing. One rl.*>resentative rock type sample from each stockpile will be submitted for petrographic analysis (ASTM C295-90). Petrographic resuhs \\ill be available three weeks after samples arc submitted.
The durability samples will be initially tested to determine the specific gra\ it~ and absorption (ASTM C97-'J7, of the rock. Further testing will take place on the sampks that receive a score over 40~'o of the maximum possible based on the ,Re '.1Conng criteria referenced below. If the initi
