(a) Category One. Those lands such as ammunition plants, storage, test, impact and training areas, bombing or target ranges, which may contain explosives or unexploded ordnance. The report will include proposed methods of neutralization and the costs thereof.
(b) Category Two. Those lands or buildings which are suspected of being contaminated with radiological, industrial-military chemicals, or explosives. The U.S. Army Toxic and Hazardous Materials Agency (USATHAMA), Aberdeen Proving Ground, Maryland 21010, will be requested to determine if the land contains any of the above contaminants, to determine the extent of the contamination, and to decontaminate, if necessary before such property is reported for disposal.
