The Department of Petroleum Resources (DPR) on Monday said it had discovered 87 filling stations operating without its approval in the last six months.
Its Director, Modecai Ladan, disclosed this in an interview with journalists on the sideline of the ongoing 17th biennial conference on Health, Safety and Environment organised by DPR.
He said that the agency had already clamped down on the illegal filling stations.
The DPR boss said that the agency was collaborating with other agencies and relevant stakeholders in nipping the problem in the bud.
He urged potential filling stations owners to be law abiding and adhere strictly to rules governing registration of filling stations.
