There are numerous case studies of failed remedial systems, which in turn can be linked to the remedial design team not fully understanding the site conditions. Often the most effective way to clean up these recalcitrant sites is source/migration control rather than intrusive remediation. The best solution can only be determined if the site is properly understood.

2004 will prove to be an interesting year for air pollution control. Just as last year, New Source Review (NSR) reform will continue to dominate the landscape with legislative, regulatory and judicial efforts to swing the pendulum in favor of particular viewpoints. Media attention on the NSR issue may overshadow equally important developments in Hazardous Air Pollutant (HAP) control, more stringent Title V permitting, implementation of new National Ambient Air Quality Standards (NAAQS) and enforcement.
