Company’s environmental programs

2019 Priorities

Updating the Tatneft Group’s Environmental Program, taking into account the new regulatory standards, including the categorization of NVOS facilities (negative impact on the environment).
Opening of the target project «Best Available Technologies” at various stages of production activity, including the procurement of technologies, materials and equipment.
Improvement of industrial environmental control, eco-monitoring, assessment of the environmental impact of the Company’s business activities.
Participation in international, national and regional environmental programs, projects and ratings aimed at achieving sustainable development.

On January 1, 2019, a large package of amendments to the Law on Environmental Protection (No. 219-FZ) came into force, establishing new rules for environmental regulation. One of the key element in the new rules is the application of the best available technologies (BAT). The requirement is aimed at reducing the negative impact on the environment. The Company participated in the development of the BAT Guide for the oil industry and is implementing a targeted project for the use of BAT in its activities.

Air protection

One of the key areas for minimizing the environmental impact is the reduction of atmospheric emissions during the Company’s production activities.

As a result of air protection efforts taken in 2018, the Company reduced the emission of pollutants into the air by 12.6% to the level of 94.036 thousand tons. Since 2016, harmful emissions into the air from stationary sources for TATNEFT Group had been reduced by 26.5%.

44 light hydrocarbons recovery units are currently operating at the Company’s facilities; the volume of recovered hydrocarbons was 24,700 tons in 2018. In general, since the introduction of vapor recovery units, since 1991, the Company has reduced its hydrocarbon emissions by 4 times.

Protection and rational use of land and forest resources

The Company addresses the issues of the rational use of land resources and soil pollution prevention with the utmost care. The land protection measures include equipping the modular rigs with tank circulation systems with three-stage mud cleaning systems. This helps to prevent liquid spillage on the land surface and eliminate the construction of earth pits as well as provide for the reliable protection of fertile lands on fertile areas against contamination from drilling fluids and formation waters.

Water protection

Reasonable and careful conservation of the ecosystem with clean water, access to water resources is one of the main factors of sustainable development. The Company makes rational use of water resources and implements measures to reduce the impact on water resources, protects and replenishes them in all regions of its presence, including by modernizing the infrastructure and introducing the best available technologies. The Company aims to increase the share of recycled and re-used water, to perform environmentally friendly handling of produced water, and to introduce modern wastewater treatment systems.

Access to water bodies used in the interests of the Company is carried out in accordance with the legislation of the Russian Federation, as well as resolutions of local regulatory bodies. The Company does not violate the right to water and access to it, including for the local population. The territories of the Company’s production activities do not belong to regions with a shortage of water resources.

According to laboratory studies, the water quality in the main rivers in the territory of the Company is maintained at a stable level, the content of chloride ions, oil and oil products in the dissolved and emulsified state does not exceed the established LOC standards for harmful substances.

Within the territory of the Company’s operations, over 500 springs were cleared, captured, and architecturally completed with the resources of the Company’s divisions.

Unique treatment facilities of the TANECO Complex

The TANECO Complex was the first in Russia to build and operate unique treatment facilities using membrane treatment technologies that provide the possibility of returning up to 80% of treated effluents to production subject to receipt and deep treatment of all generated effluents — industrial, domestic, storm. The efficiency of wastewater treatment for some substances is up to 99.9%. It allows to reduce the content of pollutants in effluents to the required maximum permissible concentrations for fishery reservoirs.

80% of wastewater is returned to production

Waste management

One of the environmental priorities of TATNEFT Group is the reduction of environmental footprint through the reduced waste generation. The Company has established a complex system of selective accumulation, collection, and disposal of production and consumption wastes and using them as a raw material to produce marketable products.

In 2018, TATNEFT Group generated 101 thousand tons of waste, including 25 thousand tons of oil sludge, 13.7 thousand tons of waste used, 4.3 thousand tons of waste neutralized at the production facilities of TATNEFT Group, including 0.095 thousand tons of oil sludge. 95.7 thousand tons of waste, including 25 thousand tons of oil sludge, was transferred to third-party enterprises.

Enterprises of TATNEFT Group operate 3 landfills. Industrial environmental control revealed no violations of the established permissible impact standards.

> 35% reduction of waste generation in own production in 2018 vs. 2017

Unique industrial waste landfill

A unique industrial waste landfill has been commissioned at the TANECO Complex, having a reliable impervious screen at its base, which eliminates the possibility of biological and chemical contamination of adjacent territories and groundwater and ensures the collection of leachate for its subsequent transportation to the treatment facilities of oil refining and petrochemical complex.

Biodiversity conservation

The Company implements the Program for the Conservation of Biological Diversity” developed taking into account legislative and other applicable requirements for biodiversity conservation and aimed at the conservation of rare species of animals by supporting existing specially-protected natural areas (SPNA) of zoological, entomological, botanical, hydrological and geological profiles and gentle (rational) environmental management in habitats of rare species.

The largest specially protected natural area of federal significance located in the region of operation of the Company is Nizhnyaya Kama National Park.

Evaluation of biodiversity by reliable indicators of the state of the environment shows that the state of eco-systems in the territory of the Company’s production activities complies with the standards.

List of objects

Protected species in the region of the Company operation

There are two species of mammals listed in the Red List of the Russian Federation and the Republic of Tatarstan — the bobac and desman (the desman is also included in the Red List of the International Union for Conservation of Nature (IUCN)).

The location of production facilities outside the habitat and activities aimed at reducing the negative impact on the environment exclude the slightest threat to the existence of these species in the region where the Company operates.

Replenishment of river biodiversity

1.7 tons of juvenile carp were released into the Kama waters in 2018, as part of the Federal Program for the Improvement of the Volga River and its Tributaries. The initiative of the Company was supported by the Middle Volga Territorial Administration of the Russian Federal Fisheries Agency and included in the plan for the artificial reproduction of aquatic biological resources for 2018.
