<br /> This SWSP previously included the Teti Pit (WDID 0203027) and the North Dahlia Pit (WDID
<br /> 0203028). A plan for augmentation for these two sites was decreed in water court case no.
<br /> 2007CW198 on December 17, 2013 and all depletions from these sites will be replaced under
<br /> the decreed plan for augmentation. The East 81h Street Pit (M-2000-082, WDID 0303016) is no
<br /> longer a part of this Combined SWSP. Holcim sold the East 81h Street Pit to Superior Oilfields
<br /> and as of November 2012 this pit is no longer covered by Holcim. All depletions impacting
<br /> the river are now covered under the East 81h Street SWSP (WDID 0302562). The Tucson Pit
<br /> (M-1991-140, WDID 0203033) was also previously included in this SWSP. Mining operations at
<br /> the Tucson Pit have been completed, and a request for a full performance and financial
<br /> warranty release for the Tucson Pit was approved by the DRMS on April 29, 2016. A portion
<br /> of the Tucson Pit (Rogers Reservoir, WDID 0203917) has been lined with a slurry wall and has
<br /> obtained SEO liner approval. All post-pumping depletions associated with the Tucson Pit
<br /> have been replaced under previous SWSPs. The remaining 2.0-acre pond is located within
<br /> the permit boundaries of the Tucson South Pit and will be accounted for and reclaimed
<br /> under that permit. The Fredstrom Pit (Plan ID 6090, WDID 0505629) operated under an
<br /> individual SWSP in 2019 and was incorporated into this SWSP starting in the 2020 plan
<br /> period. Holcim never began mining at that site and no longer intends to mine it and this pit
<br /> is no longer included in this SWSP.
<br /> The Irwin-Thomas Pit (Plan ID 5829, WDID 0505626) operated under an individual SWSP in
<br /> 2019 and was incorporated into this SWSP starting in the 2020 plan period. The DPG Pit (Plan
