<br />However, there was a small amount of water contained at the bottom <br />of the pond, and a sample was taken from this water. The results <br />were pH 7.2, TDS 336.0 mg/1, TSS 170.0 mg/1, sittable solids <.2 <br />and total iron 5.36 mg/1. It is not possible to determine if an <br />exceedance occurred at this point because of the nature of the <br />sample. <br />ACTION TAKEN <br />A contractor excavated the breached area of the dam and then <br />replaced and recompacted the soil as per standard engineering <br />practices. <br />ADDITIONAL INFORMATION <br />The storm exceeded a 10 year 24 hour event, therefore, the permit <br />limits do not apply to the effluent. This is based on the fact that <br />the pond was designed to hold the 10 year, 24 hour event and it <br />did not do so. Another contributing factor that led to such a <br />large inflow of water was an irrigation ditch that crosses the <br />facilities drainage area overflowed its banks contributing a major <br />portion of the flow that entered the settling pond. <br />If you have any questions or concerns regarding this matter, please <br />feel free to contact me at 303-527-4135. <br />CYPRUS ORCHARD VALLE-Y~~~CO-AL CORPORATION <br />/ ~(v, ~ /~"LL <br />John H.
