replacements in time, location and quantity. Fees are not required for proposed augmentation plans submitted to the water court that do not propose to expose groundwater until after a decree is entered by the water court. A substitute water supply plan may still be required if groundwater is removed in the product or groundwater is used for dust control or gravel washing. 4. The deepening of an existing pit may not warrant a substitute water supply plan. If the surface area of the existing pit to be deepened has not expanded, it is grandfathered pursuant to §37-90-137(11)(b), C.R.S., and no plan and fees are necessary. 5. The renewal fee for an existing substitute water supply plan is $217 if the renewal is made prior to the expiration of the existing plan. Plans that expire and subsequently resubmitted are considered new plans requiring a fee of $1,343.00. The fee for a gravel well permit application is $60, even if the operation is not in an over-appropriated stream system. These fees must be paid at the time of application and are not refundable. All new substitute water supply plan requests will be reviewed by an outside consultant. All renewals will be processed by the Office of the State Engineer. DEPLETIONS 6. Gross evaporation (free water surface) shall be calculated based upon evaporation atlases in NOAA Technical Report NWS 33 or more site specific information if available. Any other estimate should be within 10% of the NOAA estimate. The net replacement of depletions shall be determined as gross evaporation less any historical consumptive use credit available for the area replaced by the free water surface. The total gross evaporation estimate from NOAA 33 shall be distributed to all months. The monthly distribution for elevations below 6500 feet msl is: Jan-3.0%, Feb-3.5%, Mar-5.5%, Apr-9.0%, May-12.0%, Jun-14.5%, Jul-15.0%, Aug-13.5%, Sep-10.0%, Oct-7.0%, Nov-4.0%, and Dec-3.0%. The monthly distribution for elevations above 6500 feet msl is: Jan-1.0%, Feb-3.0%, Mar- 6.0%, Apr-9.0%, May-12.5%, Jun-15.5%, Jul-16.0%, Aug-13.0%, Sep-11.0%, Oct- 7.5%, Nov-4.0%, and Dec-1.5%. The percentage distribution of evaporation will still apply for periods when ice cover occurs. 7. Water consumption by the gravel operation including, but not limited to, dust control, water removed with the mined product, and reclamation irrigation must also be determined. From previous experience, 4% of the product mined (i.e., any product excavated from below the groundwater table or any product excavated above the groundwater table and washed) by weight is water. All water diverted from the pit shall be measured. All diversions, including water for dust control and irrigation for vegetation establishment, shall be considered 100% consumptive unless it can be documented otherwise. 8. Any dewatering operation that results in an exposed free water surface that will not be backfilled or lined upon reclamation shall need sufficient replacement water available in the event the dewatering pumps were stopped for any reason. If the final
