a direct or indirect negative impact on the environment shall be conducted in

compliance with environmental protection requirements. Measures for

4

environmental protection, restoration of the environment, sustainable use and

renewal of natural resources, and environmental safety shall be put in place@.

The principal objectives of environmental monitoring are:

shall be the responsibility of legal entities or individual entrepreneurs, which have sources of

harmful chemical, biological, and physical impact on the atmospheric air, and which shall

appoint persons responsible for industrial monitoring of atmospheric air protection and/or

organize environmental protection services.”

During the course of monitoring, legal entities shall protect atmospheric air in

accordance with the air protection laws of the Russian Federation.

2.3 Sanitation and hygienic control (monitoring)

Sanitation and hygienic monitoring is regulated by RF Law No. 52-FZ “On Sanitary and

Epidemiological Wellbeing of Population” dated March 30, 1999? In accordance with the Article

11 of which the entities and organizations must:

environment during operation;

Assessment of the identified changes in the environment, and forecasting of potential

adverse consequences;

Obtaining data on the release of various types of waste into the environment during

construction and operation;

5 Test results

5.1 Groundwater monitoring

The main groundwater monitoring objectives are as follows:

Monitoring of groundwater levels and quality;

Timely detection of groundwater quality changes to take the measures required to

prevent any potential impact on water quality.

The groundwater level was determined based on its depth below ground level.

Two monitoring wells used to monitor the levels and chemical composition of

groundwater are located near the leach fields of the Odoptu-2 (North) WS.

The test well is 15 m to the south of the leach fields.

10

The baseline well is 15 m away from the northwest corner of the leach fields

(upstream along the groundwater flow).

The wells drilled near the temporary waste storage site (TWSS) at the Odoptu-2 (North)

WS are intended for monitoring of the chemical composition and levels of the groundwater in

the potential TWSS impact area.

The baseline well is located upstream of TWSS (along the groundwater flow) and

designed for monitoring of the chemical composition of groundwater before it flows

past TWSS.

The monitoring well is located downstream of TWSS (along the groundwater flow)

and designed for monitoring of the chemical composition of groundwater after it flows

past TWSS.

Observation well flushing at Odoptu-2 (North) Well Site

In 2018, the Odoptu-2 (North) Well Site observation wells were flushed.

The ice plugs in the TWSS wells were also drilled out in 2018. The primary goal of these

activities was to restore/maintain the observation wells in order to accomplish operational

control and monitoring program.

The work was performed in June - July of 2018.

5.1.1 Water Table Monitoring

The groundwater level was determined based on its depth below ground level.

Measuring instruments: electrical level gauge EU-100.

Parameters to be measured: depths of occurrence.

The results of level measurements in wells are presented graphically in the figure below

(Figure 5.1).

Groundwater level fluctuations in monitoring wells near Odoptu-2 (North) WS leach

fields are minor and seasonal.

5.1.2 Groundwater quality monitoring

Monitoring of groundwater chemical quality indicators was performed in monitoring wells

near leach fields located at the Odoptu-2 (North) WS.

Groundwater for laboratory analysis was sampled quarterly.

Sampling was performed using the PE-1105 sampler after well flushing and water level

recovery.

Samples were stored and preserved per GOST 31861-2012. Description of the

measurement procedures used for studies is presented in Table 5.1-1.

Measured pH values range from 5.4 to 7.0 and are consistent with the typical values for

natural waters. Based on рН values, groundwater in the monitoring well in the first quarter was

found to be slightly acidic (pH = 5.0-6.5), in the second quarter –neutral (рН = 6.5-7.5) before

well flushing and slightly acidic after well flushing; in the fourth quarter - neutral both before

and after well flushing. In baseline well No. 5, groundwater in the first quarter was found to be

neutral, while in others –slightly acidic (pH = 5.0-6.6) both before and after flushing.

Groundwater conductivity ranges within 100-791 µS/cm.

Water analysis results showed that the characteristics in the monitored well did not

exceed that in the baseline well.

5.2 Monitoring of subsoil and interbed crossflows

Monitoring of subsoil and interbed crossflows, areal spread of drilling and other process

wastes within the site, as well as spread of formation water injected into a dedicated well was

performed in 2018.

The above scope included monitoring of the level and quality of groundwater in

monitoring wells at the Odoptu-2 (North) WS.

Groundwater for laboratory analysis was sampled quarterly in 2018.

Sampling was performed using the PE-1105 sampler after well flushing and water level

13

recovery.

Samples were stored and preserved per GOST 31861-2012.

The results of level measurements in wells are presented graphically in the figure below

(Figure 5.2-1).

Figure 5.21: The groundwater level trend graph in monitoring wells near leach fields at the Odoptu-2 (North) WS.

Groundwater level fluctuations over the entire monitoring period ranged:

in well D-1 – from 10.18 m to 11.5 m.

in well D-2 – from 7.33 m to 8.97 m.

Groundwater level fluctuations in monitoring wells at the Odoptu-2 (North) WS are minor

and seasonal.

Groundwater level and quality measurements demonstrates that value fluctuations do

not exceed the natural changes in groundwater levels at the monitoring site, and groundwater

chemical composition in the specified wells shows that the groundwater is not affected by

drilling wastes, other process wastes, and produced water injected into the dedicated well.

5.3 Monitoring of injected wastewater quality

Wastewater, process wastes, and drilling water is injected in injection well at the Odoptu-

2 (North) WS.

Before injecting wastewater is sampled to determine its quality.

Immediately after sampling, the water was placed in a dedicated sample storage

container (per GOST 17.1.5.04-81).

Injected wastewater does not impact the air, water, bottom sediments and animals

because it is injected into a single disposal horizon from active, backup and buffer zones in the

interval 1700-2450 m (TVDSS) with no direct contact with the above-mentioned environments.

According to the process flow diagram, drilling and other process wastes are injected

into an injection well with no negative effect on surface ecosystems (soils, surface and

groundwater).

5.4 Monitoring of gray water quality

Wastewater quality control includes monitoring wastewater composition and physical

and chemical properties at treatment facility inlets and outlets to assess operating efficiency of

these facilities.

Wastewater from the BOKS-200 treatment facility located at the Odoptu-2 (North) WS

was sampled from January through December for microbiological, parasitological and chemical

characteristics.

5.4.1 Overview of treatment facilities

The BOKS station is intended to receive and deep treat sewage and wastewater of

similar composition from small population centers, hotels, and tourist complexes. The capacity

of the BOKS-200 treatment facility is 200 m³/day. The facility has a common wastewater

receiving tank. After treatment, wastewater is discharged to leach fields.

BOKS-200 treatment station is fitted with a UV disinfection unit, as well as а sludge filter

to dewater sludge.

16

BOKS-200 treatment station at the Odoptu-2 (North) WS is modified for operations in

The measured level of thermal radiation (irradiance) emitted by the flare unit at Odoptu-

2 WS (North) is within the allowable limits established by SanPiN 2.2.4.3359-16 “Sanitary and

Epidemiological Requirements for Workplace Physical Factors” for white and red hot surfaces

(incandescent or molten metal, glass, flame, etc.) which are equal to 140 W/m2 in all directions.

Thermal radiation levels are completely within the regulatory limits.
