Sanitary protection zone

Effective 1st January 2018, a new sanitary protection zone (SPZ) was been established within the Karachaganak Field.

Since 2018, KPO carries out the upgrade of Unit-2 and drilling new wells located within the previous SPZ boundary. Prospective facilities of the future field development — KEP-1A and KEP-1 are scheduled post 2020.

The residents of Berezovka and Bestau villages, which fell within the boundaries of the estimated SPZ, were resettled in 2015-2017 to Aksai in locations with more favourable housing conditions in terms of the sanitary and hygienic standards.

The dimensions of the new Karachaganak SPZ are not the same in different directions and vary from 5,000 m on south-west to 9,440 m on south-east. In other words, size of the estimated SPZ is between 5,007 m and 7,579 m from the line of the outermost sources. The SPZ map is shown in figure below.

In 2019, KPO continued the phased move of the existing environmental monitoring stations (EMS) to the new boundaries of the SPZ area. In total, 11 stationary EMSs were subject to relocation. In December 2018, three existing EMS Nos. 10, 13, and 14 were moved and hooked up. In 2019, KPO relocated three more stations — Nos. 11, 16, and 18. All relocated stations function as normal. The remaining five stations will be moved during the 2020 as per the 2020 EPMP for KOGCF.

In 2019, as part of the implementation of the KOGCF SPZ further development plan for 2018-2026 KPO organized archaeological research within the KOGCF and SPZ area with the involvement of the KAPE LLP together with the specialized co-executor the Archaeological Expedition LLP.

The activities were conducted in order to exclude negative impact on the historical and cultural heritage sites (further as HCH), as well as to identify such sites, clarify their characteristics and location, and issue recommendations for their protection and/or study. The identified HCH sites will be taken into account during the prospective design, excavation and construction works.
