<br />ok. Are we planning some type of formal internal/external policy announcement? If so, I'll hold off on making this
<br />request of the operator, and see what shakes out. It seems like this might be the type of issue that we need to formalize
<br />with a memo to operators, outlining the justification and ensuring consistent application, so specific operators don't think
<br />we are capriciously picking on them. I suppose Scullion flows a couple miles from pond discharge to river. I would think
<br />it would be best to measure effluent at the pond discharge CDPS sample point, as there could be some dilution in
<br />Scullion (though not often). Maybe you should take a look at the site though. Let me know when. Let me know if I
<br />should wait for a formal policy memo, wait for you to visit the site, or just go ahead and request the monitoring plan
<br />amendment, and hope for the best?

<br />Dan, refer to segment 12 of White River Basin - "mainstem of the White River from a point immediately above the
<br />confluence with Piceance Creek to a point immediately above the confluence with Douglas Creek including Taylor
<br />Draw Reservoir."
<br />Receiving stream standards for that segment are designated for NH3, CI2, CN, S, B, N02 and N03, CL, SO4, As,
<br />Cd, Cr III and IV, Cu, Fe, Pb, Mn, Hg, Ni, Se, Ag and Zn. Requirements would be to monitor both the river upstream
<br />and the effluent. We are leaning to measuring worst cast -hence, analyzing the river at a low-flow period and the
<br />discharge at high Flow. That way we can demonstrate that we are, in fact, watching out for stream quality.
<br />Since it actually dumps into Scullion Gulch, how far is it from the discharge point to the river and does any water get
<br />to the riven Maybe it would be best to measure it where it flows into the river. We ought to discuss this. Maybe
<br />even take a look sometime when I'm out that way.

<br />Jim: Thanks for the quick turn-around on the McClane/Munger and Deserado AHR's. Regarding your
<br />questions; the blue stippled area on the McClane map must be projected water level in the sealed workings, but I
<br />will request that the text be amended to clarify. For Deserado--The only NPDES site which has discharged in the
<br />last five years is Pond DP-1 at the D Portal Area. It essentially discharges continuously due to use of water for
<br />dust control, belt washdown, etc. in the processing plant. Direct discharge is to Scullion Gulch, and thence to the
<br />White River. It would seem to be the logical discharge point to focus on if we need to specify additional
<br />parameters for analysis. Let me know the parameters and frequency for analysis, or any additional information I
<br />should request from the operator.
<br />.
