He played a key role in the development, Congressional passage and implementation of the Clean Air Act Amendments of 1990. After passage of that landmark law, Rob focused on innovative, cost-effective ways to implement its provisions, particularly through the use of market-based approaches such as emissions trading and other economic incentives. He was a leader in EPA's efforts to promote development of new, more effective pollution-control technologies such as diesel retrofits, and pioneered the use of economic analysis in evaluating the effectiveness of EPA programs.

Rob was also very active in nurturing and developing voluntary partnerships with local organizations to help them reduce pollution in their neighborhoods. The flagship program was Community Action for a Renewed Environment (CARE), a cross-media toxics reduction initiative. Rob successfully incubated this concept, and turned it into an EPA program helping more than 100 communities nationwide to reduce exposures to toxic chemicals.
