Enclosed is the May 2009 DMR for 005A. No <br />exceedances were noted. As we discussed in late June, the original permit rationale and the carbon copies for the monthly <br />DMR that we received from CDPHE omitted TR iron but indicated weekly sampling for total iron as Fe, which is what was done <br />in May. This may have been missed when the permit requirements for outfalls 003A and 005A were switched. Sorry for the <br />confusion. We have noted the problem, and will follow the appropriate template in future reporting. <br />Very truly yours, <br />Brian A.
