cubic meters) is planned to be released from the leaking gypsum pond, which contains high levels of uranium and other toxic metals. Releasing such a large amount of contaminated waste water into the environment would help take pressure off from the pond's containment structure, which has softened as a consequence of the recent spring thaw. Freezing winter temperatures had kept the waste water from leaking during the previous four months, but the renewed leak on 8 April 2013 has demonstrated that this temporary advantage has now been lost. It is presently not clear if the mining company will wait for the integrity of the pond to fail in a catastrophic way, or if they will move ahead with an unauthorized release of waste water. It is unlikely that a permit will be granted in time that would allow a more managed response. The regional office of the Finnish Economic Development, Transport and the Environment (ELY Centre) has apparently adopted a wait and see policy, as its mandate to monitor both economic development in the area and environmental concerns seem to be at odds, and such internal confusion tends to limit the ability of ELY to make such important decisions. It is also unclear if the company's insurance policy will cover cleanup if the Talvivaara company goes into bankruptcy. On 12 April 2013, Talvivaara Mining Company submitted another application to release additional quantities of waste water into the local environment.

sufficient to advance the schedule by several months. Certainly the company was eager to recover from the serious financial losses that came with the accidental leak that began last year, and an earlier restart should help to restore the bottom line for this troubled fiscal year. According to the company, the resumption of ore production will improve overall water levels and site water management. Apparently this improvement will come through dissolving the contaminated waste water with more clean water. Additional waste water was leaked this spring to relieve stress on the walls of the leaky holding pond that was repaired last winter, to make room for the larger volumes of diluted waste water that is expected from the new waste management plan. There was no public mention of creating larger or additional holding ponds at this point, nor the possibility of simply cutting back on production.

764: 705: 908:. Thus, the local environmental agencies, which were previously governed independently, were placed under the jurisdiction of an officer responsible to the Ministry of Employment and the Economy. Indeed, the ministers responsible, Paula Lehtomäki and Jyri Häkämies, gave the responsibility for all the environmental permits and regulation of the Talvivaara mine to a single official. Häkämies, the Minister of Economic Affairs, resigned shortly after the event. Prof. Hukkinen demands that the independent environmental administration should be re-established such that it could be openly critical of business interests. 812:(gills and livers, respectively). However, with aggressive liming, acidification has been successfully limited and no fish kills have materialized. The Finnish National Institute for Health and Welfare (THL) has declared that waste water leaked from the Talvivaara mining "has no immediate serious effects on human health". The Finnish Radiation and Nuclear Authority (STUK) reported uranium levels 3.5 times higher than the recommended limit of 100 micrograms per liter, but not high enough to be acutely dangerous to humans. In March 2012, the concentration of 858: 943:) deficiencies in the planning and safety control of the plant for the metal recovery were the cause of the accident. A lethal concentration of hydrogen sulfide was released outside the leach residue pond of the metal recovery plant. The mining company had already before noticed the hazard, but the reasons for increased concentrations of hydrogen sulfide were not found out systematically. Shortage of defining responsibilities, flow of information, operations and working habits of the organisation were also discovered in the investigation by 38: 3207: 300: 726:, published an editorial column that labeled the company "a large-scale failure, that casts a shadow on the efficiency of the Finnish society as a whole", criticizing Finnish officials for not taking administrative action against the mining company for its environmental problems.

In a pilot heap, over 90% of nickel and 80% of zinc was recovered within 500 days of leaching. Cobalt and copper recoveries were lower, 14% and 2%, respectively.

On Monday 15 April, Hautala criticised Solidium's actions in the Talvivaara case, saying that the government investor (Solidium) should have engaged in serious reflection, since Talvivaara could not by any means be considered a good investment.

The higher acidity allowed much higher concentrations of toxic metals to dissolve and spread into the environment when a leak occurred. Talvivaara had attempted to conceal this from the public and the government, hindering for instance the EU inquiry.

Talvivaara's head of production, admitted that "...less than 400,000 cubic metres of waste water had escaped the pond" recently, which is considerably more than the 250,000 cubic meters that were suggested to have leaked on 8 April 2013. This is the fourth major discharge from the mine since 2008, with three in the last six months.

On 9 April 2013 it was announced that the recent leak has been plugged, and the Talvivaara mining company was quick to claim that there is no fear that the leak might resume again.
