Greenpeace activists, on their ship the MY Arctic Sunrise, prevent the tanker Probo Koala from leaving port in the harbour of Paldiski, September 25. Oil trader Trafigura denied waste it offloaded in Ivory Coast was poisonous, saying independent analysis showed the chemical sludge blamed for seven deaths met international safety standards. However, Greenpeace has maintained pressure over the scandal by blockading the tanker, the Probo Koala, in Paldiski and demanding a European probe. -

ABIDJAN, Ivory Coast (Reuters):

A chain of administrative failures and negligence in Ivory Coast led to the dumping of toxic waste in the economic capital Abidjan, which killed 10 people and made thousands ill, a government inquiry said.

Poisonous chemical slops unloaded from a tanker chartered by Dutch-based oil trader Trafigura in August were dumped at 17 mostly open-air sites around Abidjan, causing vomiting, diarrhoea, nosebleeds and nausea among its residents.

Fatou Diakite, head of a national inquiry commission appointed by Prime Minister Charles Konan Banny, said negligence by the port and customs authorities, city administrators and government ministries enabled the disaster to happen.

"Problems linked to lack of rigorous management, failure to observe professional ethics and non-application of regulations ... favoured the entry and dumping of toxic waste in the District of Abidjan," Diakite said in excerpts of the report published on Thursday by state media.

The Government resigned at the height of the scandal, but a mostly-unchanged cabinet was appointed 10 days later. Abidjan's port director, the customs chief and the head of the District of Abidjan have been suspended pending investigations.

The report singled out as 'the main actor' in the scandal Salomon Ugborugbo, the Nigerian manager of the Tommy company, which was contracted by Trafigura to dispose of the waste.

Fraudulent collusion

The waste disposal company was set up just before the Probo Koala tanker docked in Abidjan.

The inquiry said Tommy was not equipped to treat the waste and said its ability to obtain permits to operate from the Transport Ministry and port pointed to 'fraudulent collusion'.

Ugborugbo and two French directors of Trafigura are detained in Abidjan and face charges under Ivory Coast's poisoning and toxic waste laws. They are among 18 people to have been arrested in a separate judicial investigation into the affair.

Premier Banny previously told Reuters everything led him to believe Tommy was set up with the sole aim of ridding the Probo Koala of its poisonous load.

Toxic substances

The report said Trafigura had violated the Basel Convention which outlaws the shipping of toxic substances to developing countries and said its subsidiary, Puma Energy, which stocks oil products in Abidjan, played a 'determining role' in the dumping.

Trafigura denies any wrong-doing or responsibility for the dumping and has called for the two directors to be released.

Pierre Djedji Amondji, head of the Abidjan District administration, was also slammed by the inquiry for his slow reaction and "surprising indifference" to the tragedy, which triggered panic in the densely-populated city.

The waste's noxious fumes, which smelled strongly of garlic, had wafted across parts of Abidjan, prompting many residents to don paper masks. But they have since subsided and a clean-up operation by French hazardous waste experts has now finished.

The dumped slops and contaminated earth have been loaded into sealed containers and shipped to France, Ivory Coast's former colonial ruler for treatment there said.
