The purpose of this letter is to follow up on issues identified during the informal conference held
at the fire station in Nucla on February 18, 2010 regarding Permit Revision No. 6 at the New
Horizon Mine. Several of the issues participants discussed during the informal conference had
been identified in the Division's January 22, 2010 initial preliminary adequacy review (PAR). A
follow -up meeting was held with Western Fuels - Colorado (WFC) representatives on March 16,
2010 to review the PAR letter and the informal conference.
In Section 1 below, we address the PAR issues that require additional information based on what
we heard at the informal conference. The numbers are consistent with the numbering in the
January 22 letter. Section 2 of the letter identifies additional issues raised during the informal
conference that will need to be addressed by WFC. Numbers follow sequentially from where the
PAR ended.
Section 1— Preliminary Adequacy Review Issues Additional Comments
11. The parcel of Begay Fine Sandy Loam soil (Map Unit 98A) in the northwest portion of
the permit area along Tuttle Draw, has been confirmed as being Prime Farmland (see
letter of February 19, 2010, from Jim Boyd, NRCS Norwood Resource Conservationist).
A 2.3 acre portion of the Begay parcel was disturbed by construction of Sediment Pond
013. The disturbed area will need to be reclaimed in accordance with prime farmland
requirements and will need to meet prime farmland criteria for bond release. Any further
disturbance within the unit will need to be conducted in accordance with prime farmland
soil handling and reclamation requirements. Please revise relevant narrative and maps
(including pertinent text in Sections 2.04.3, 2.04.9, 2.05.4(2) (d), 2.05.4(2) (e), and Maps
2.04.9 -1, 2.05.4 -4 and 2.05.4 -5) as appropriate.
