January’s Environmental Historical past has a overview by Leif Fredrickson of Michael Combine’s Leaded: The Poisoning of Idaho’s Silver Valley (OSU Press, 2016). From the overview:

The toxic historical past of the Bunker Hill Firm must be as well-known to environmental historians because the Battle of Bunker Hill is to historians of the American Revolution. Situated within the Silver Valley in northern Idaho, Bunker Hill mining and smelting operations polluted the encompassing space and poisoned residents and employees with lead for a century. Within the 1970s, Bunker Hill’s operations wrought “the worst group lead publicity drawback in the USA,” in response to the Facilities for Illness Management and Prevention. The silver lining to the Silver Valley catastrophe was that it fueled new and stronger nationwide rules for lead air pollution.

In Leaded, Combine seeks to unearth the “root causes” of mining and smelter air pollution within the Silver Valley. He argues that air pollution went unabated for a lot of the twentieth century as a result of the federal government sought to empower Bunker Hill within the pursuit of financial improvement and western settlement. Countervailing forces had been both too weak or too depending on the corporate to withstand the large air pollution externalities the corporate foisted on others. Employees and Silver Valley residents usually spurned criticism of the corporate—“Uncle Bunker” as locals referred to as it—for concern of shedding the world’s key employer. Equally, state politicians feared shedding a thriving enterprise and a supply of taxes. Bunker Hill’s financial and political energy produce favorable laws and the corporate benefited from judges and regulators who sided with the business over labor and people harmed by air pollution. Bunker Hill’s energy was additionally rooted in information. The state authorities lacked the assets to know a lot of what Bunker Hill knew, or may have identified, concerning the poisoning of employees and the group.

Till the 1970s, the federal authorities did nothing to vary this case. Federal courts doled out, at finest, piddling compensation for land and livestock poisoned by mines and smelters. Federal environmental legal guidelines had been weak till President Richard Nixon created the Environmental Safety Company (EPA) and Congress handed laws that might power states to fulfill air and water air pollution requirements. In the meantime, in 1973, a fireplace destroyed a part of Bunker Hill’s already outdated air pollution management system. However with lead costs hovering, the corporate selected to proceed working its smelter anyway. The ensuing widespread poisoning of kids in the neighborhood, which got here to gentle over the 1970s, catalyzed the EPA’s first air lead commonplace, promulgated in 1977, and supplied proof for a comparatively low acceptable lead degree. In response to Combine, the air lead commonplace, together with extra stringent occupational well being requirements, “signified an finish for many western lead smelters,” since they might not profitably meet the brand new know-how necessities. Bunker Hill shut down in 1981.
