Native delegation from the Bristol Bay region attended the annual shareholder's meeting of Anglo American, the major mining company behind the Pebble project. The delegation met with Cynthia Carroll, CEO of Anglo American, claiming that the Bristol Bay watershed is no place for an open-pit mine. Multiple UK jewelers pledged not to buy gold from the Pebble mine if it is built, joining several American jewelry retailers and manufacturers who had done the same in 2008. The Natural Resources Defense Council (NRDC) and other well known groups and figures (such as actor Robert Redford) have opposed the construction of the mine. In an effort to stop or pause the construction of the mine, the NRDC has created a petition that now has more than a million signatures. The environmental justice nonprofit, Earthworks, has more than 100 gold buyers who have agreed to boycott gold from the Pebble Mine. These retailers include Tiffany & Co, Jostens, and Zales, along with others. After the EPA invoked its power to veto the mine proposal, Alaska politicians expressed various positions. Governor Mike Dunleavy and Attorney General Treg Taylor expressed opposition to the decision and support for the mine. Senator Lisa Murkowski expressed support for the decision but also concern for the precedent it set, and stated that "this must be the only time the EPA ever uses its veto authority under the Clean Water Act in Alaska." Representative Mary Peltola expressed support for the decision to protect Bristol Bay. Arguments against the proposal Opponents to the mine point out that it is about jobs—current sustainable fishing (world class fishery with long history and that is perpetually sustainable) versus the time-limited mining employment that the mine will generate. (All mines have limited lifespans.) The fish in the watershed, and the wildlife that depend on them, are too important to risk in exchange for the mine's economic benefits. (Bristol Bay is the most valuable Sockeye Salmon fishery in the world — employing more than 14,000 people and generating $1.5 billion in annual profit.) Accidental discharge of process chemicals and byproducts, heavy metals, and acid mine drainage to the environment are concerns in mine design and operation. Heavy metals are mobilized by acids. Downstream salmon and freshwater fish species are vulnerable to mine-generated pollutants. A threat to the fisheries would amount to a threat to the regional subsistence lifestyle. Hard-rock mining already has a notable track record
