Already being fined by the European Union for landfill violations, Greece could face more penalties with the European Commission asking the bloc’s top court to impose costs for failing to protect waters against pollution caused by nitrates from agriculture in compliance with an earlier court ruling.

In April 2015, the European Court of Justice (ECJ) ruled Greece violated EU law by failing to protect its waters against pollution caused by nitrates from agricultural sources. “Four years later, the problem is still not fully resolved,” the Commission said in a statement, the news agency Reuters said.

The Commission asked the court to impose a fine of 2,639 euros ($2984.50) per day on Greece for each day since the initial April 2015 ruling that Greece has failed to comply, providing Greece does so before the next ruling of the EU court.

If the country does not comply, the Commission wants the ECJ to raise the fines to 23,753 euros ($26,862.74) per day. There was no report of any response from the ruling Radical Left SYRIZA government which has ignored other EU court findings.
