New Permit Application, Surface Water Hydrology Adequacy Review
I have finished my adequacy review of the surface water hydrology aspects of the new permit
application for the New Horizon North Mine. The following are my adequacy review questions and
comments:
1. In Section 2.04.7 of the permit application, mention is made of Tuttle Draw and Coal Canyon
in the regional surface water description and in the site specific surface water description.
However, no mention is made until much later in the discussions of the two tributaries of Coal
Canyon, namely Glasier Draw and Meehan Draw, and the tributary of Tuttle Draw, namely
Nygren Draw, which pass through the permit area and which appear on Map 2.04.7-1 and Map
2.05.3(3)-1. In order to avoid any confusion, please explain early on in the text descriptions that
Glasier Draw and Meehan Draw are tributaries of Coal Canyon and that Nygren Draw is a
tributary of Tuttle Draw.
2. On page 13 of Section 2.04.7, Tuttle Draw and Coal Canyon are described as being perennial
streams. Please describe the stream classifications for Glasier Draw, Meehan Draw and Nygren
Draw.
3. In the Surface Water Monitoring section on page 15 of Section 2.04.7, it is stated that there are
10 surface water monitoring stations, numbered SW-N200 through SW-N209. These 10 sites
also appear in Table 2.04.7-5 on page 17 of Section 2.04.7 as well. However, on Map 2.04.7-1,
"Hydrologic Water Monitoring Locations", site SW-N210 also appears. Please explain.
4. In the two sentences before the last sentence in the Surface Water Monitoring section on page
15 of Section 2.04.7, a discussion involving SW-7, SW-6 and GW-7 is presented. However,
these three sites do not appear on Map 2.04.7-1 and GW-7 would be a ground water monitoring
site. Please explain and modify the text discussion if appropriate.
5. In the last paragraph on permit application page 15 of Section 2.04.7, it is stated that surface
flow at NHN is totally dependent on the irrigation water from the 2nd Park Lateral ditch system.
