The quarry and the ocher factory of the Société des Ocres de France are installations respectful of the environment, classified as ICPE, and regularly inspected. For the washing of ocher, they use closed-circuit water pumped and discharged into old ocher galleries with minimal loss through infiltration. As for the rainwater, it is collected in a large basin to avoid its runoff and the pollution of the Coulon river. Finally, an anti-dust device installed on the factory's chimneys purifies the ocher calcination fumes and limits air pollution.
