How are stakes identified

Piles treated with toxic tar oil

Wilhelmshaven / Friesland/ jm After the storm surge on November 1, 2006, the sheep pasture fences on the dike in the Rüstersieler Groden were renewed. Now you have to assume that the woods used are impregnated with toxic tar oils and do not comply with environmental regulations.

Suspicious fence sections have also been identified in the Friesland district. According to the district, the woods will soon be removed, the III. Oldenburgische Deichband refers to the ongoing proceedings and does not want to take a position at the moment.

Even more than a year after the fence was erected on the dike in the area of ​​the NWO bridge, a thick, sticky covering can still be seen on many piles. When the sun is shining, the black surface heats up, the covering seems to liquefy and its smell can be perceived from several meters.

At the beginning of the year it became known to experts that wooden stakes from Poland are being traded in north-west Germany that do not meet the legal requirements. However, the Oldenburg Trade Inspectorate (GAA) has apparently been dealing with the illegal timber since mid-2007.

A checked wholesaler had initially submitted certificates according to which the proper quality of the wood could be assumed, said the head of the authorities, Uwe Rottmann. However, further investigations and chemical analyzes would have shown that limit values ​​were exceeded in the dealer's inventory. Thereafter, further placing on the market was prohibited.

The responsible dyke band does not want to disclose when exactly the wood was used on the Jade dike. Gert Bartels, Managing Director of the Water and Soil Associations, refers to an ongoing process. He doesn't want to name the supplier either.

Until recently, the Lower Saxony State Agency for Water Management, Coastal and Nature Conservation (NLWKN) in Norden assumed that tar oil-impregnated wood had not been used for coastal protection "for decades". Press spokeswoman Herma Heyken suspected that the suspicious piles were not wood, but recycled material (polyolephone piles). Heyken had to correct himself at the beginning of April: You were amazed to learn from the Brake operating office that your information no longer existed. However, further details are not available from the press spokeswoman or from the NLWKN's Brake operating office, and the Lower Saxony Ministry of the Environment cannot provide any clarification.

The city of Wilhelmshaven, which is responsible for the coastal area at the NWO bridge, would also like information. You hear about the problems with the wood on the dike for the first time, says Gerold Janßen from the Department of Environment. Now his department is first trying to determine the current status.

In the district of Friesland one is already further: After a site inspection on May 7th, the III. Oldenburgische Deichband asked for a statement and commissioned an expert institute to carry out analyzes. According to press spokesman Rainer Graalfs, the wooden posts do not pose any acute danger, but the wooden posts have to be removed.
