<br />Notes: ° All soil would come from North Elk Creek Soil Stockpile except for satellite facilities, which each have their own soil stockpile lonly satellite

<br />' No soil was recovered for the majority of this area Ipre-law disturbancel. Soil volumes shown were recovered during recent mine facilities
<br />expansion. ,
<br />Z Facilities have been reclaimed, with available stockpiled topsoil or suitable surficial materials used in reclamation.
<br />~ Powerline roads have been disturbed by Delta-Montrose Electric Association and are not mine disturbance.
<br />° As short-term disturbances, all soil recovered from borehole sites and roads has been windrowed adjacent to disturbance and directly replaced on
<br />completion of disturbance (volumes not measuredl.
<br />° Since no soil was recovered from original disturbance areas, use of suitable surficial materials as revegetation medium has been approved and
<br />will be supplemented with available excess soil from other areas, with priority on areas where surficial materials are marginal to unsuitable.
<br />° Soil replacement depth for West Valley Fill will be 1 foot with 0.7 foot replacement depth for the remainder of disturbance area.
<br />Although soil was not originally salvaged from this area, available excess soil from other areas will be used to enhance revegetation success.
