Russian regulators warn TGC-11 over suspected toxic emissions in Omsk

Regulators in Russia have issued a formal warning to Omsk-based PJSC TGC-11 over suspected emissions breaches. The notice, dated 24 June 2026, follows reports of pollution levels exceeding safe limits in the city. Authorities have called on the company to address its environmental obligations. Elevated emissions of hazardous substances were detected in Omsk between 31 May and 12 June 2026. On 12 June, readings at a monitoring station on Kosmichesky Prospect showed hydrogen sulfide levels 2.5 times above the maximum permissible concentration (MPC). During the same period, another station on Uchebnaya Street recorded hydrogen sulfide at 1.12 to 1.5 times the MPC.

In April 2026, ammonia levels had already exceeded the MPC by 1.86 times, according to data from Rosprirodnadzor. Regulators suspect that violations at TGC-11’s facilities may have contributed to these spikes. The warning cited potential breaches of multiple environmental protection laws and urged the company to take corrective action.

The warning is preventive and does not confirm any violation. TGC-11 retains the right to file an objection to the notice. The company must now respond to the warning and implement measures to comply with environmental standards. Regulators will continue to monitor emissions in Omsk to ensure pollution levels remain within legal limits. The case highlights ongoing scrutiny of industrial compliance in the region.
