Existing surface impoundments were required to complete the Location Restrictions demonstrations no later than October 17, 2018. Because the Gypsum Pond was certified closed by removal on March 11, 2017 and could no longer contain CCR or liquids, these demonstrations were not completed.

 
Existing surface impoundments were required to complete Design Criteria demonstrations no later than October 17, 2016. Because all CCR removal from the Gypsum Pond had been completed by this date, and the pond could no longer contain CCR or liquids, these demonstrations were not completed.


Existing surface impoundments were required to prepare a Fugitive Dust Control Plan and initiate annual inspections no later than October 19, 2015. The Initial Inflow Design Flood Control Plan was required no later than October 17, 2016. Because all CCR removal from the Gypsum Pond had been completed by October 17, 2016, and the pond could no longer contain CCR or liquids, these demonstrations were either not completed or are no longer necessary.

Existing surface impoundments were required to install and comply with groundwater monitoring requirements no later than October 17, 2017. Because all CCR removal from the Gypsum Pond had been completed by this date, and the pond could no longer contain CCR or liquids, these demonstrations were not originally completed. 

Because the Gypsum Pond was certified closed by removal on March 11, 2017, this unit is not subject to post-closure care requirements in 257.104.

Because the Class 2 Landfill was closed on February 28, 2017, the Fugitive Dust Control Plan and Annual Fugitive Dust Reports are no longer necessary.
