Environmental protection has become a top priority for states and local governments, but it has been a difficult task for state and local governments to balance competing priorities. Fortunately, the last 25 years have seen a dramatic shift in state government's approach to environmental protection, bringing new and more effective tools to the table. With an expanded professional staff and robust two-party systems, states have embraced the concept of public participation in the development of environmental policy and have become more open to new ideas than ever. The EPA has many functions. It is responsible for protecting the environment and reducing risks of pollution. It also oversees compliance with regulations and provides procedures for working with hazardous materials. It also inspects storage areas and vessels to ensure safety and prevent contamination. It also creates environmental emergency plans to respond to any spills that might occur. While the EPA plays a key role in a number of federal programs, it isn't always a front-line government agency. The EPA has several programs that promote energy efficiency and environmental care. In addition, the agency also focuses on pollution prevention. It is important to note that not all environmental concerns are handled by the EPA. For example, the U.S. Fish and Wildlife Service handles environmental concerns regarding endangered species. The Army Corps of Engineers is responsible for protecting wetlands. While the EPA imposes significant costs on businesses, critics say the agency is a burden on the economy. However, it stands by its mission of promoting a cleaner environment and protecting human health.
