German auto component major Bosch Ltd on Monday resumed operations at its two manufacturing plants near a polluted lake in the city after a two-day shutdown on the directive of the state pollution control watchdog.

"We have resumed operations at our Adugodi and Koramangala facilities in the city on receiving clarification from the Karnataka State Pollution Control Board that the provisions of its May 5 notice were not applicable to the plants here," said the company's India arm in a statement in Bengaluru.

The company on Saturday temporarily closed its twin plants located in the vicinity of the 910-acre polluted Bellandur lake in the city's south-east suburbs on the Board's notice against it and other firms in its catchment areas.

The Board issued the notice on the April 19 order of the National Green Tribunal to shut down all industries in the lake's vicinity for saving and restoring it.

Asserting that it had the highest standards to protect the environment, Bosch said it was confident of operating the plants within the prescribed norms.

"As we have regard for environment protection and legal norms, the operations were shut as a precautionary measure and informed the watchdog that we follow stringent environment standards, practiced globally in production locations," asserted Bosch India President Soumitra Bhattacharya in the statement.

Following the notice, the company took sewage and effluent treatment measures to resume production at both plants near the lake.

"We do not foresee financial impact or turnover loss owing to the temporary closure," added Bhattacharya.
