The release incident <br />was discovered on April 29, 2013 at approximately 7:00am. The fire water system is a component of the <br />Mill Process Water Storage Tanks, which are collectively, designated as Henderson Mill Environmental <br />Protection Facility 1.2 in the Henderson Mill Environmental Protection Plan. When the leak was <br />discovered, an estimated 5,000 gallons of water had leaked reporting to the yard just north of the Loci <br />Shop. An additional 8,500- 14,000 gallons were released following the leak due to an unknown partially <br />open valve. <br />The following paragraphs correspond to the elements of the follow -up written notice set forth in Rule <br />8.2.3, paragraphs (a) through (e), of the DBMS Rules and Regulations: <br />(a) After discovering the issue, Henderson employees promptly turned off the valves to the <br />line to stop any additional release. When it was discovered 48 hours later that there was <br />still water escaping from the leak, the valves were fully turned off. <br />(b) The water release did not adversely impact human health, property or the environment. <br />This is based on the know chemistry of the water and the location of the event. Water <br />pooled around the point of release (i.e., in the yard just north of the Loci Shop) but did not <br />flow from this area. <br />(c) The contact person for this event is: <br />Amber Moran <br />19302 County Road 3 <br />Parshall, CO 80468 <br />Phone: 303 - 569 -3221 ext. 2235 <br />
