RE: Roadside Mine Preliminary Review of 2003 AHR Division Director
Permit No. C-1981-041 Natural Resource Trustee
I have conducted a preliminary review of the 2003 Annual Hydrologic Report, recently
submitted by Snowcap Coal Company. The report covers the water year October 1, 2002
through September 30, 2003. I am requesting a hydrologist review for PHC compliance
evaluation. Jim Burnell has done this review in the past.
The format and content of the report is largely consistent with previous reports. Monitoring
has been conducted at the locations and in accordance with the schedule in the approved
permit. An updated Monitoring Location Map has been included in this year's report. Based
on my preliminary review, there do not appear to be any obvious discrepancies or
inconsistencies in the data (recall that last year there was apparently erroneous TDS data
for one of the UTL wells).
The data appear to me to be consistent with PHC projections, and there are only a couple
minor items that we may need to have clarified:
1) Narrative regarding Minewater Discharge Point 015, on Page 3, is outdated and will need
to be amended. Specifically, the third paragraph indicates that "the site is permitted to
allow pumping water from the south end of the Roadside South Portal out the 2 West
Portals". In fact, this site was never used for discharge, the portal has been sealed and
reclaimed, and the discharge site is now officially "inactive".
2) I'm not sure how significant this is, but I wanted to bring it to Jim B's attention, and
request his comment (assuming he does the PHC conformance review). Tfie permit was
amended last year to specify reporting of "dissolved" constituents, rather than "total", for
the annual full suite monitoring. Dissolved constituents were reported, with a couple
exceptions. In Table SU-2, NPDES Point 016 (Minewater Dischargel, Chloride, Fluoride, and
Phosphorus are reported as "Total", rather than "Dissolved". Chloride is also reported as
"Total" on Tables GE-10 and GE-11, for Rollins Wells 2 and 3. Also, the approved surface
water monitoring list (applicable to minewater discharge) specifies that phosphorus be
reported as phosphate, but as noted, in Table SU-2, it is reported as "Phosphorus, Total".
Those are the extent of my concerns. Please pass this memo along to Jim for the
hydrologist of your choosing), along with my request for the PHC conformance review. The
AHR should be arriving in the Denver office by Monday (I received my copy yesterday).
Thanks
