Russian regulators warn TGC-11 over Omsk's toxic air pollution spikes

Regulators in Russia have issued a formal warning to Omsk-based energy company TGC-11. The notice, dated 24 June 2026, follows repeated instances of elevated pollution in the city. Authorities suspect the company’s facilities may have contributed to the high readings. From 31 May to 11 June 2026, monitoring stations in Omsk recorded excessive levels of hazardous substances. On 12 June, a station on Kosmichesky Prospect detected hydrogen sulfide at 2.5 times the maximum permissible concentration (MPC). Another station on Uchebnaya Street showed hydrogen sulfide levels between 1.12 and 1.5 times the MPC during the same period.

Earlier, in April 2026, ammonia levels had already exceeded the MPC by 1.86 times, according to data from Rosprirodnadzor. Regulators linked these spikes to potential violations by TGC-11’s operations. The warning urges the company to adhere strictly to environmental protection laws.

The document clarifies that the warning is preventive and does not confirm any breach. However, TGC-11 retains the right to formally object to the notice. The preventive measure highlights ongoing concerns about air quality in Omsk. TGC-11 must now address the warnings and ensure compliance with environmental standards. Failure to do so could lead to further regulatory action.
