Maria/Matt, 

The following is the explanation regarding soil disturbance. 

RESPONSE TO THE EIS NRC FOLLOW UP QUESTIONS ABOUT SOIL REMOVAL DURING 

CONSTRUCTION OF THE IIFP HOBBS NM FACILITY.

Excavation and Grading For Pre-Construction and Phase 1 Construction: 

Pre-Construction 

The 40-acre IIFP Facility site will be leveled by grading to provide an approximately level grade at Elevation 

3797 ft. Approximately 26 acres on the northeast will be cut approximately one foot in depth resulting in a cut 

of an estimated 42,400 cubic yards. This cut will be used as fill in the northwest and southwest areas and in 

two small playas on the west side of the site (approximately 18 acres). The amount of fill required will be 

approximately 42,600 cubic yards, resulting in a deficit of 200 cubic yards of fill that will be obtained from the 

640 acre site. 

Phase 1 Facility Construction (Excavation)

During construction, a 2-ft depth of topsoil (approximately 3100 cubic yards) will be removed in the areas of 

buildings and adjacent pads to provide adequate bearing for concrete floors/pads. Additionally, an estimated 

4000 cubic yards will be removed at an approximate 2-ft depth in the areas for the full-and empty- depleted 

uranium hexafluoride cylinder pads. The fill back to the required level will be made with material having soilcompacting specifications suitable for the load bearing requirements that will be determined later during the 

detail engineering of the project. 

Foundations and footings for buildings, tanks and equipment and for evaporation basins and the storm and 

sanitary sewer systems will require excavation of an equivalent 4150 cubic yards (excavation less backfill). 

The roadbed for the access road from Highway 483 to the 40-acre site will require approximately 8800 cubic 

yards of fill. This fill is expected to done by using most of the 11,250 cubic yards of material that will come 

from the excavations described in the above two paragraphs. Any excess (or unsuitable fill material) will be 

spread approximately 6” deep and compacted over an estimated one-to-two acre area of the 640 acres and in 

this case material will be obtained from suitable areas of the 640 acre site for building the roadbed. (Note: the 

roadbed work was originally described in the ER RAI responses as part of the Pre-construction timeframe. It is 

now considered as part of the Phase I construction owing to the timing of the available backfill obtained from 

the subject Phase 1 construction excavations. The grading and temporary preparation of a construction-access 

road will be included in the Pre-Construction activities. These noted changes will be documented in the 

updated IIFP Environmental Report, Revision B along with inclusion of the RAI response updates.)

John, 

 

Attached is a response to the EIS subject question. Please review for concurrence and send an 

email with the response attachment to Maria and those other NRC staff on the original "cc". 

Note that Maria's comment on the "10% soil being disturbed" was a general statement in the ER/RAI 

that less than 10% of the total site (640 acres) area would be disturbed; it does not correlate to the 

amount of soil removed.

Maria,

We will work on this and send a response via email.

John,

The EIS folks have asked how much soil would be excavated during preconstruction and construction and 

what would be done with it? Also, how deep the excavation will be for the soil removal? I did a quick look in 

the RAI responses and found that only 10% of the soil will be disturbed. Do you think it would be possible to 

provide this additional information via email?

Please respond as soon as possible to avoid any delays in the DEIS..

Thanks,

Maria Guardiola
