ENVIRONMENT, INC. <br />APRIL 26, 201 O <br />PAGE 3 <br />Exhibit E - Reclamation Plan (Rule 6.4.5) <br />All information needed to satisfy section 3.1.5(9) items (a)-(f) of the rule concerning the use of off-site and <br />structural fill. The application states that an intent to import inert fill letter and inert material affidavit are <br />included, but these could not be found in the submitted application package. <br />I forgot to include the letter and affidavit in the submittal <br />packet. Attached are 2 copies for the file. <br />Exhibit G - Water Information (Rule 6.4.7) <br />Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock water ponds, reservoirs, and <br />ditches on the affected land and on adjacent lands where such structures may be affected by the <br />proposed operations. <br />All of the Maps contain the water features you have listed as <br />they exist. <br />Please also provide the following information: Are there any wells within 600 feet of the permit area? <br />The exceptions to what I noted above are the water wells <br />within 600 feet of the permit area. Map Exhibit G-1, at- <br />tached, shows all water wells within 600 feet of the proposed <br />,lake area (blue cross hatching) as listed in the office of the <br />State Engineer's records for this area. Attached to this map <br />are printouts of the information for each well shown. We have <br />shown2 wells owned by Vogl, which do not show up in the state <br />records and after talking to Mr. Richard Vogl, I found out <br />that they were installed before 1972 and are not registered. <br />We request that this map'be accepted as a supplement to the <br />Pre-Mining Plan map as it better shows the water well loca- <br />tions on and around the site. <br />Is any portion of the site within the 100 yr flood plain of the St Wain Creek? <br />Yes, Attached is an excerpt from the FEMA map for this area. <br />Note that the existing permit area is the"only area within the <br />100 year floodplain for St. Vrain Creek. <br />Where are the existing or proposed groundwater level monitoring points? Please locate on <br />appropriate maps and provide construction details (depth, screened intervals etc.) <br />Currently there are 13 groundwater monitoring points on the <br />property. Their location is show on Map Exhibit.G-2. At- <br />tached to this map is a sketch showing the typical construc- <br />tion details for these wells. The monitoring holes were <br />drilled to bedrock. <br />What is the current static water level and does the permittee already have the required 12 months (and <br />preferably more) of background groundwater level data to establish baseline conditions prior to commenc- <br />ing dewatering? <br />Attached to Map Exhibit G-2 is the groundwater monitoring data <br />collected from each well monthly. Monitoring began on Wells 1' <br />thru 5 in October 2006 and continue monthly. Wells 6 thru 14 <br />were installed in January 2009 so we have a little over a <br />years worth of data. The water table fluctuates on average as <br />much as 6.6 feet across the site each year so there is no <br />static water level on the site. In general the average eleva- <br />tion is from a high of 4808 on the south to 4795 on the north. <br />Is there a groundwater level monitoring plan for the site to monitor for potential off-site impacts to the <br />aquifer, establish trigger points for corrective actions, and describe what corrective actions would be <br />implemented?
