Design and implementation of a supplemental control program for SO, episodes in the region of Ho, Peru J. Jackson, P.

In this region, large SO, emissions from a copper smelter plant affect the local air quality and sometimes cause elevated SO, concentration values in the City of Ilo. SC>2 emissions are expected to be drastically reduced in the next decade. To alleviate the present situation, a Supplemental Control Program (SCP) has been implemented. The SCP includes our interactive Intermittent Control System (ICS) software which is based on a large set of data (emission, meteorology, and air quality) collected in the region and transmitted in real time to a central computer system. These on-line data allow th
