The Clean Air Act Amendments of 1990 did all of the following except:

The Clean Air Act Amendments of 1990 indeed expanded the regulatory scope of the Act, addressing additional issues that had not been covered by earlier legislation. It introduced measures to control acid rain, ozone depletion, and toxic air pollutants, effectively broadening the range of pollutants regulated by the Environmental Protection Agency (EPA). This reflects the Act’s intent to adapt to emerging environmental challenges and provide comprehensive air quality management.

The amendments also aimed to create more consistency with other environmental regulations, facilitating integrated approaches to pollution management across different sectors. By establishing clearer standards and regulatory frameworks, the amendments sought to align air quality measures with water and waste management goals.

However, while the amendments are significant for their regulatory expansions, managing and improving air quality, the Act did not specifically reauthorize funding for the EPA in a new way. This aspect relates to the broader context of environmental legislation, where funding is often subject to separate appropriations processes rather than being directly integrated into legislative amendments. Thus, the misconceptions about funding can lead one to assume it was reauthorized as part of these amendments.
