<br />7.-5-. The renewal fee for an existing substitute water supply plan is $217. A substitute water
<br />sLiWly plan application will only be considered a renewal if the plan is received by the
<br />Office of the State Engineer prior to the expiration date of the previously approved plan,the
<br />plan does not change the he replacement sources(s) and does not add additional uses that were
<br />not approved in the original plan. A renewal can increase the quantity of water which is
<br />consumed by the uses which were originally =roved.,
<br />expiration of the e?��g plan. Plans that expire , change the
<br />replacement source(s), or add new uses in addition to those uses approved in the on 'nal
<br />plan are considered new plans requiring a fee of $1,343.00. The fee for a gravel Ltt well
<br />permit application is $60480, even if the operation is not in an over - appropriated stream
<br />system. These fees must be paid at the time of application and are not refundable. An
<br />outside consultant will review all new substitute water supply plan requests. The Office of
<br />the State Engineer will review presess-all renewals. Once the substitute water supply plan
<br />has been approved by the Office of the State Engineer anysubseguent amendments will
<br />require submittal of an engineering report and $217 filing fee or $1,343 filing fee
<br />ft ending nding on the nature and extent of the amendment.
<br />DEPLETIONS
<br />8.6: Gross evaporation (free water surface) shall be calculated based upon evaporation atlases in
<br />NOAA Technical Report NWS 33 or more site - specific information if available. Any other
<br />estimate, including site - specific information, should be within 10% of the NOAA estimate.
<br />The net replacement of depletions shall be determined as gross evaporation less any
<br />historical consumptive use credit available for the area replaced by the free water surface.
<br />Phreatophyte credit, including effective precipitation, cannot be claimed for mining
<br />operations which were not approved under a permit issued by the Division of Minerals and
<br />Geology. The total gross evaporation estimate from NOAA 33 shall be distributed to all
<br />months. The monthly distribution for elevations below 6500 feet msl is: Jan-3.0 %, Feb -
<br />3.5%, Mar -5.5 %, Apr -9.0 %, May - 12.0 %, Jun - 14.5 %, Jul- 15.0 %, Aug - 13.5 %, Sep - 10.0 %,
<br />Oct -7.0 %, Nov -4.0 %, and Dec -3.0 %. The monthly distribution for elevations above 6500
<br />feet msl is: Jan-1.0 %, Feb -3.0 %, Mar -6.0 %, Apr -9.0 %, May - 12.5 %, Jun - 15.5 %, Jul- 16.0 %,

<br />9. Pursuant to §37- 90- 137(11)(b), C.R.S., the applicant is not required to account for
<br />depletions that occur due to evaporation form ground water exposed within the ermit
<br />boundaries prior to January 1, 1981. If the applicant can demonstrate that the mining
<br />operation has removed ground water surface area exposed prior to January 1 1981 the
<br />applicant can claim credit, against evaporation, for the Pre -81 surface area. Credit is
<br />available only within the boundaries of the original Division of Minerals and Geology
<br />boundary area that existed for the gravel operation at the time that the area was exposed.
