The camp was used to house "minimum-custody-type improvable male offenders," who had no more than one year to serve. These were violators of national defense, wartime and military laws. Included were conscientious objectors, violators of rationing and price support laws, those convicted of espionage, sabotage and sedition and those convicted by military courts martial. Aliens who failed to register were also in this category but none of them were sent here because the camp was located on the southern edge of the 670 square miles (1,740 km2) Hanford Site.
