WHY DOES DEC MONI TOR ACI D RAI N? STATE ACID DEPOSITION CONTROL ACT (SADCA) MANDATE � INCREASED SPATIAL ACID RAIN MONITORING COVERAGE � ACROSS THE STATE ESPECIALLY IN ECOLOGICALLY SENSITIVE REGIONS, SUCH AS THE ADIRONDACKS. MORE THAN HALF OF DEC ACID RAIN SITES MONITOR OTHER � POLLUTANTS INCLUDING SO 2 , O 3 , PM 2.5 AND METEOROLOGICAL PARAMETERS. DEC MONITORS ARE LOCATED IN SUBURBAN, URBAN AND � RURAL AREAS. 11/9/2005 3
