She has worked on a number of the Sierra Club’s political campaigns, among them, efforts to improve Ohio’s brownfield (toxic waste) sites. She was also involved in a petition to USEPA to revoke Ohio’s authority to implement environmental laws due to past failure to enforce these laws. This effort led to numerous agency reforms. Marilyn's major projects are stopping pollution (again) at Cleveland-Cliffs steel mill in Middletown, pushing for Green Steel and stopping sewer overflows in Hamilton County. After years of no progress in stopping overflows, Marilyn worked to bring a citizen suit against the sewer district. Cincinnati and Hamilton County both now have a consent decree which is the first in the nation to recognize sewage reaching people’s basements as violations of the Clean Water Act.
