Ban Dung district

Ban Dung (บ้านดุง, ) is a district (amphoe) in northeastern Udon Thani province, Isan, Thailand.

Geography
Neighbouring districts are (from the south clockwise) Thung Fon, Phibun Rak, Phen, and Sang Khom of Udon Thani province, Phon Phisai and Fao Rai of Nong Khai province, and Ban Muang, Charoen Sin, and Sawang Daen Din of Sakon Nakhon province.



North of Ban Dung are marshlands and open water called Nong Pla Tao.

The major river is the Songkhram, which marks the boundary of the district to the east.

History
The minor district (king amphoe) Ban Dung was established on 16 May 1959, when three sub-districts were split off from Nong Han district. It was upgraded to a full district on 16 July 1963.

Central administration
Ban Dung is divided into 13 sub-districts (tambons), which are further divided into 159 administrative villages (mubans).

Local administration
There is one town (thesaban mueang) in the district:
 * Ban Dung (Thai: เทศบาลเมืองบ้านดุง) consisting of sub-district Si Suttho and parts of sub-district Ban Dung. The town is divided into 34 communities (chumchon).

There are 12 sub-district administrative organizations (SAO) in the district:
 * Ban Dung (Thai: องค์การบริหารส่วนตำบลบ้านดุง) consisting of parts of sub-district Ban Dung.
 * Dong Yen (Thai: องค์การบริหารส่วนตำบลดงเย็น) consisting of sub-district Dong Yen.
 * Phon Sung (Thai: องค์การบริหารส่วนตำบลโพนสูง) consisting of sub-district Phon Sung.
 * Om Ko (Thai: องค์การบริหารส่วนตำบลอ้อมกอ) consisting of sub-district Om Ko.
 * Ban Chan (Thai: องค์การบริหารส่วนตำบลบ้านจันทน์) consisting of sub-district Ban Chan.
 * Ban Chai (Thai: องค์การบริหารส่วนตำบลบ้านชัย) consisting of sub-district Ban Chai.

Economy
The district is the site of a Voice of America (VOA) relay station, built in 1994. The Voice of America will give the station to Thailand, but will be allowed to operate it under a 25-year renewable lease expiring in 2019. Each of the station's seven shortwave transmitters is capable of broadcasting 500 kilowatts of power, covering 40 per cent of the Earth's surface. One of the transmitters will be dedicated for use by Radio Thailand. It will have sufficient power to reach the Middle East and the West Coast of the United States, both areas with large expatriate Thai communities.

The VOA installation has been suspected of being a CIA black site used to interrogate alleged terrorists. That suspicion has been supplanted by a BBC report that the Udon Royal Air Force Base was the home of a CIA black site, known to insiders as "Cat's Eye", but better known as "Detention Site Green", used to interrogate Abu Zubaydah, a 31-year-old Saudi-born Palestinian, believed to be one of Osama bin Laden's top lieutenants. In December 2014 the United States Senate Select Committee on Intelligence (SSCI) published an executive summary of a secret 6,000-page report on CIA techniques. The report alleges that at least eight Thai senior officials knew of the secret site. The site was closed in December 2002. Thailand has denied the existence of the site while the US government has neither confirmed or denied its existence.

Ban Dung district is also the largest source of rock salt production in the Isan from the past to the present.
