Divismn Duecta
The Division has reviewed your annual report for 1994, received on February 2, 1995.
Overall the report is well organized and meets all of our rcquirements. Of particular interest
was your report on reclamation activities and the detailed hydrologic reports. It appf:ars that
despite the dry growing season, your revegetadon efforts continue to be successful.
We do have two items of concern. First, on page 31 you discuss a possible lease
modification with the U.S. BLM concerning acreage adjustments for the BLM lease. Will
this affect the Division's p<:tmit boundaries?
Secondly, the data on pages 92 and 93 -Section 6.1.6 and Table 6-16 indicate that leakage
from the waste and process ponds is increasing. Do you plan to attempt to eliminate [he
leakage? If not, could you demonstrate that it is not a problem? Please notify the Division
in the next 30 days if the trend of increased leakage continues.
Because of the possibility of an adverse impact on groundwater quality due to leakage from
the waste or process water ponds, or other leakage from the production wells or the
production complex, the Llivision is requesting that White River Nahcolite Minerals L. L.
Co. submit to the Division a groundwater monitoring program which complies with
Rule 3.1.7(7). The plan should include points of compliance as described under
Rule 3.1.7(6) and should establish permit conditions, including numeric protection levels,
protective unclassified groundwater uses as described under Rule 3.1.7(1), (2), (3), and (4).
As stated in Rule 3.1.7(5), the submittal will be considered a Technical Revision. The
Division realizes that the majority of this requested information has been submitted either in
the original application, irl Amendment No. 2, or in [he "Comprehensive Monitoring Plan for
Commercial -Scale Solution Mining of Nahcolite", but believes that a single comprehensive
document as described in Ruie 3.1.7(7) is needed, which i;.cludes permit conditions and
