regulated under CDPS permit # 0027154). Please additionally ask the lab that conducts
your WET tests if any portion o£ the Pond E discharge left over from the full-suite
analysis could be WET-tested. So that the information described above may be obtained and
discussed with us before we consider this step abated, we are extending the abatement
deadline for this step from today to tomorrow.
Step 6e: We understand that developing the estimate o£ the total slurry (water plus
solids) volume discharged to Foidel Creek will take a few days to prepare. Because of
this, and because this particular abatement step is not as critical as some of the others,
we are extending the deadline for this step from today to Friday October 6 2006.
Step 6f: Due to the extensions for Steps 6a, 6b, 6d, and 6e, we are extending the
deadline for this step (submittal o£ a written report providing the information from the
Step 6 steps} from today to Friday October 6 2006.
Step 8: We agree that this step, in its original form, is open-ended. We will
therefore modify this step to "Continue all approved surface water quality monitoring as
required by CDPHE; provide to CDRMS a copy of the September 2006 DMR for permit #
0027159." As the abatement deadline for this step is currently October 30, 2006, we will
leave this deadline unchanged at this time.
Steps 9, 10, and 11: As discussed, we are leaving the abatement measures and deadlines
for these three steps unchanged at this time.
A Modification Notice (to change the requirements of Step 8), an Extension of Time for
Abatement Notice (to document the extended deadlines described above), and a letter
documenting that Step 6c has been abated, will be sent to TCC as soon as possible. Please
contact me if you have any questions.

Extension Request
Jerry -- I have modified Step 6 of NOV CV-2006-006 by breaking it down into six new Steps:
6a, 6b, 6c, 6d, 6e, and 6f. Each of these new Steps will now have their own individual
abatement deadlines. I did this because it appears that some o£ the abatement measures
from the original Step 6 have been abated, and that others may still be unabated. We can
discuss the specifics of what's been abated, what's left to abate, and the remaining
abatement deadlines on Monday Oct 2nd when you return from your vacation.
I have extended the deadlines on Step 5, Steps 6a through 6f, and Step 7 to Monday Oct
2nd. Before extending these deadlines beyond this date, I would prefer that you and I
discuss on Monday what remedial actions have occurred at the mine site since your last
communication (below).
A Modification Notice (changing the original Step 6 into new Steps 6a-6f) and an Extension
of Time For Abatement Notice (extending the Sept 29 2006 deadlines for Steps 5, 6a-6f, and
7 to Oct 2, 2006) were faxed to you today. These Notices will be put in the mail as well.
