Abstract
With the understanding and cooperation of local residents, Japan’s first PCB-treatment waste facility was established in Kitakyushu City in December 2004. Since then, the city has taken an initiative to conduct a detailed questionnaire survey on PCB-containing products in order to better control and eliminate their presence in the region. The questionnaire survey targets not only business operators that must disclose usage of electric facilities for private use, but almost all of the businesses in the city. Some businesses, however, have failed to respond to the survey. For such companies, the city has made every effort to continue its investigation into the total amount of PCB-containing materials at large: including conducting second rounds the questionnaire survey, follow-up phone contact，and on-site inspections. The survey is also important as it provides businesses with information regarding the places where PCB-containing units have been used or are stored. Through its detailed questionnaire survey conducted with 50,000 businesses four times during the years 2008 to 2014, Kitakyushu City has been able to successfully grasp an actual figure for the number of waste PCB units to be controlled.
