This book examines the efforts by the Environmental Protection Agency (EPA) to protect human health and the environment for overburdened populations by developing and implementing guidance on incorporating environmental justice into the EPA's rulemaking process. All too often, low-income, minority and tribal Americans live in the shadows of the worst pollution, facing disproportionate health impacts and greater obstacles to economic growth in communities that cannot attract businesses and jobs. Every American deserves clean air, water and land in the places where they live, work, play and learn. The EPA hopes to lead by example in expanding the conversation on environmentalism and working for environmental justice, now and in the future.
