The purpose of this project is to proactively replace the SGP South Hydrocarbon Drain
(DHC) header line which has experienced corrosion damage in recent years. The DHC
is designed as a closed system to prevent the release of hydrocarbon liquids and vapors
to the atmosphere.

Water Recycling Facility Upgrade The purpose of this project is to treat sanitary wastewater effluent from the Water
(WRF) Project
Treatment Facility (WTF) to technical water quality standards and further reuse within
TCO Operations. TCO is currently working on the Ultrafiltration (UF) pretreatment
system for the wastewater which will be installed and commissioned in 2016.

Wastewater System Monitoring
Improvement
The purpose of this project is to evaluate monitoring improvement alternatives for
wastewater systems to ensure robust wastewater monitoring, improve process and
source control practices/objectives through defensible flow, sample collection and
measurement and improved data management practices.
Alternative Water Sourcing Study The purpose of this study is to continue evaluation of technically feasible alternate
water supplies that would enable TCO to further reduce its fresh water consumption
and draw from the Volga (Kigach) river. To include: Caspian Sea, ground water,
additional recycling to water recycling facility.
Waste Recycling Program
The purpose of this program is to evaluate additional recycling opportunities to further
reduce the amount of waste disposed into the landfill. Continue developing recycling
culture in TCO and its contractors.

Environmental effect (expected results)
Current State: Under the current plant design, a series of low-probability events could
potentially result in release of acid gas or sour gas to atmosphere from KTL T-301 tank
vent.
Measures to be taken: Modify process scheme to remove tank T-301 from the main Unit
300 circulation loop.
End result: In the event of a power outage or other process upset this modification will
reduce risk of acid gas or sour gas release from tank T-301.
Current State: The existing SGP South DHC header line has experienced corrosion and
has been repaired as a short-term measure.
Measures to be taken: The SGP South DHC header line will be replaced.
End result: Reduce potential for environmental impacts from loss of containment from
the SGP South DHC system and ensure safe and reliable operation.
Measures to be taken: Evaluate alternatives to reduce potential upset SO2 emissions
End result: Implement the preferred alternative to reduce sour gas flaring.
Current State: The WRF has been constructed as per initial Basis of Design. Further
evaluation of WTF effluent characteristics identified need for additional filtration. Pilot
UF system installed and operated over several months determined that an UF unit with
sand bed filters was necessary for operation.
Measures to be taken: Project team is currently working on the UF system design,
procurement, installation, and commissioning to be completed in 2016.
End result: WRF will provide technical quality water from recycled sanitary wastewater.
UF system is required to be commissioned prior to operation of WRF plant.
Current State: The existing wastewater monitoring system is mostly manually operated.
Measures to be taken: Installation of measuring equipment (flow meters, auto samplers,
analyzers) to automate existing system.
End result: Improved data collection capability, including sampling and measuring,
improving data management practices for wastewater discharges.
End result: Identification of technically feasible water supply alternatives for TCO

Air Protection
Bypass the tank T-301 tank by installing
additional valves and re-routing of Unit
300 process piping.
The purpose of this project is to reduce the risk of acid gas or sour gas release to
atmosphere in the event of a power outage or other process upset. The proposed
modification would effectively remove tank T-301 from the main Unit 300 amine
circulation loop resulting in risk reduction. Under current plant design, a series of lowprobability events could potentially result in release of acid gas or sour gas from the
atmospheric amine surge tank (T-301).

Current State: Currently TCO recycles more than 40% of its generated waste.
Measures to be taken: Evaluate and assess additional waste recycling opportunities.
Increase recycing waste volume and identify and develop capable Kazakh Content
recyclers.
End result: Increase recycing waste and diversion rate. Promoted recycling culture among
TCO and contractor employees.Support development and growth of Kazakh Content
recyclers.
Current State: TCO has disturbed lands that are subject to reclamation.
Measures to be taken: Development/implementation of reclamation projects, and return of
reclaimed lands.
End result: Preserve soil and vegetation. Ecosystem restoration.
