Following
the CPC Marine Terminal (MT) emergency control and recovery, and after the
local emergency regime was lifted on August 30, 2025, constant monitoring of
the sea water state in the CPC MT water area and nearby areas is provided by
the accredited third-party laboratory.
Starting
evening of August 30, 2025 to date, samples are taken at five control points
twice a day – in the morning and in the evening, a total of 10 samples per day.
Environmental monitoring information as of August 30 is available at the link.
According
to the updated monitoring data, no exceedance of the maximum permissible
concentrations (MPC) of pollutants in the water was recorded on August 31 and
September 1, 2025, the data sampling plan is attached. It should be noted that
the MPC standard for the content of petroleum products in fishery basins is
0.05 mg/dm3.
Sampling point map is attached:
- CP1 - to the east of CPC-2 SPM, in the direction of Shirokaya
Balka,
- CP2 - at 1,000 m towards the shore from CPC-3 SPM
- CP3 – opposite the Durso village beach,
- CP4 – opposite the Frigate Resort (Sukhaya Schel ecosite),
- CP5 – Maliy Utrish area.
CP1 control point was selected in order to confirm that
the oil slick had not propagated to the east of CPC-2 SPM. CP2, CP3, CP4, CP5
control points were selected based on the oil slick trajectory at the time of
the spill.
Furthermore,
shoreline monitoring is provided on a constant basis in the CPC MT water area
and in the area of Yuzhnaya Ozereevka and Khutor Durso. No oil contamination of
the shoreline was identified. Notably, no sorbents were used during the
emergency response operation. Samples maps Aug 31-Sep 1
