The decision by the Andean country’s Environment Ministry late Saturday is actually nothing new. In January 2017, a proposed auction of the La Oroya smelter, supported by President Pedro Pablo Kuczynski, drew the interest of five companies.
But the interested parties were turned off by Peru’s air quality standards. At the time, the prospective buyers were aware of the possibility of changes to the regulations and decided to hold off on bidding until they could see for themselves what would come of the new standards.
However, according to Reuters, the government’s new proposal is serious and would include changing several parts of the country’s environmental quality standards, including raising the sulfur dioxide emission limit to levels in line with other countries in the region including Chile, Colombia and Mexico.
The country is desperate to sell the plant, as well as a small copper mine. The government is planning a new series of auctions before an August deadline for selling the facility. The proposed standards have been pre-published and are now open for a 10-day public comment period.
Of course, the proposed standards change does not mention the need to sell the smelter, but to some environmentalists, it looks like Peru is putting the environment second over economic growth, something President Trump has done in the United States.
Pollution problems with the La Oroya smelter
La Oroya was bought by Doe Run, (whose parent company was The Renco Group, Inc.), in 1997 for US$247 million. The company also bought a small copper mine, the Cobriza copper mine, south of La Oroya, for US$7.5 million. Until Doe Run took bankruptcy in 2009, they owned 99.97 percent of La Oroya.
La Oroya was made up of a copper and lead smelter and zinc refinery. The plant also dealt with ‘dirty concentrates’ produced by a number of local mines. They included gold and silver, antimony, arsenic trioxide, bismuth, cadmium, indium, selenium, tellurium, sulfuric acid, and oleum.
