Jared Dains February 3, 2011 Page 5 1. This SWSP shall be valid for the period of November 1, 2010 through October 31, 2011, unless otherwise revoked, modified, or superceded by decree. If this plan will not be made absolute by a water court action by the plan's expiration date, a renewal request must be submitted to this office with the statutory fee (currently $257 per site) by September 15, 2011. 2. The total area of pond surface exposed at the Mann Lakes, Riverbend Operation and Lupton Lakes after December 31, 1980 for each of the unlined pits shall not exceed those values listed in Table A of this approval. Should the total surface area exposed exceed those amounts, an amendment will need to be filed with this office. The total lagged depletions resulting from operation of the pits shall not exceed those amounts specified in attached Table 1. Should the lagged depletion from any of the pits exceed the values listed in Table 1, an amendment will need to be filed with this office. 3. All pumping for dust control shall be measured in a manner acceptable to the division engineer. 4. Stream depletions from the proposed gravel pit operation were lagged to the South Platte River. For purposes of this SWSP, the distance of the exposed ground water to the river ("X") is accepted; however, should the Applicant seek to renew this SWSP, the Applicant must calculate the depletions with the X value measured from the centroid of the ground water pond. 5. All diversions shall be measured in a manner acceptable to the division engineer. The Applicant shall install and maintain measuring devices on all the wells nos. 1657-RR, 2819-F, 19944-FR, 20317-R and 20583-R as required by the division engineer for operation of this SWSP. In addition, since well nos. 1657-RR, 2819-F, 19944-FR, 20317-R and 20583-R, are also included in the Central GMS decree in case no. 2002CW335, the Applicant shall install two (2) 'flow meters on these wells to separately record all pumping covered by Central GMS and all pumping covered by this SWSP. 6. Adequate accounting of depletions and replacements must be provided to the division engineer in Greeley (Div1 Accounting Astate. co. us) and the water commissioner (Scott Edgar at Scott.Ed4ar@state.co.us) on a monthly basis or other interval acceptable to both of them. Since the Applicant intends to pump the well nos. 1657-RR, 2819-F, 19944-FR, 20317-R and 20583-R for both irrigation and industrial uses a monthly meter reading for each use on each well shall be reporting in the accounting. The accounting form provided with your application is subject to modification and approval by the division engineer. All amounts shall be in acre-feet. In addition, the applicant shall submit a report from each entity making replacements; for this plan, that entity is the City of Aurora. The report shall include an accounting of all wastewater plant water effluent controlled by each entity, showing the total volume of water under its control at the various wastewater treatment plants, and the amount committed to each of the recipients of the water. Furthermore, ongoing water budget accounting is required on Mann Lakes in accordance with the State Engineer Guidelines for Lining Criteria for Gravel Pits. Any groundwater that enters Mann lakes shall be released to the stream and cannot be put to beneficial use. 7. All releases of replacement water must be sufficient to cover all out of priority depletions and be made under the direction and/or approval of the Water Commissioner(s). The replacement
