Public utilities provide electric, gas, water or telephone service to customers in a specified area. Utilities have a duty to provide safe and adequate service on reasonable terms to anyone who lives within the service area on without discriminating between customers. Because most utilities operate in near monopolistic conditions, they can be heavily regulated by local, state, and federal authorities. Generally, the local and state agencies are called Public Service Commissions (PSC) or Public Utility Commissions (PUC). Municipal Utilities and Rural Electric Cooperatives may be unregulated though.
Silver Bay is a city in Lake County, Minnesota, United States. The population was 2,068 at the 2000 census. The city attained wide-spread publicity in the 1960s when it was discovered that the Reserve Corporation was dumping taconite tailings into Lake Superior. In 1972 they were forced to stop and charged with violating the Rivers and Harbors Act of 1899, which prohibited the dumping of harmful materials into interstate waters. In 1977, after a long trial, a new waste-storage facility was built 7 miles inland. State Highway 61 serves as a main arterial route in the city.
