During the month of March 2003, DMP 001 did not <br />discharge. DMP 004 and DMP 007 did not exceed any compliance criteria in March 2003. Due <br />to an oversight in the new discharge permit requirements, the quarterly Total Dissolved Solids <br />(TDS) samples were not collected for DMP 004 and DMP 007. The oversight has been brought <br />to the attention of the field personnel. <br />DMP 004 and DMP 007 both passed the chronic WET tests for the first quarter of 2003. <br />Please contact me at (307) 742-0031 with any questions or comments you have regarding <br />this matter. <br />SL:gh <br />Enclosures <br />File: 99-144 <br />Project Engineer <br />
