ISSUE: BANNING CYANIDE USE IN MINING

Existing State Law

Montana
Initiative 137, now § 82-4-390 of the Montana Code Annotated - On November 6, 1998, the citizens of Montana voted 53% to 47% to support a citizen’s initiative, proposed by Montana Environmental Information Center (MEIC), to phase out open pit, cyanide-leach mining in Montana. The citizen’s initiative has withstood numerous legal challenges and has been unsuccessfully appealed by mining companies several times.

Nevada
These Nevada statutes, 502.390 and 501.181, require a mining operation which uses cyanide to track wildlife mortality rates in order to get a permit. The program has been in place for ten years and, during this period, wildlife mortalities at mine sites have decreased dramatically. Down from 2,000 total individual animal mortalities in 1986 to just over 300 in 1997, the goal of the Division of Wildlife is to attain zero mortality at mine sites. Twenty-nine active mines accomplished this level of excellence in 1997 out of a total of one hundred permit holders.

Proposed Legislation

Colorado
A Colorado legislative committee killed SB 03-026 in the 2003 session. The bill proposal was sponsored by Senator Ken Gordon, and would have banned new open-pit mines that use cyanide. Although 11 Colorado counties supported the bill, Colorado legislators were under intense pressure from mining industry interests (Colorado is the corporate headquarters for the two largest international gold mining companies). The bill has not been reintroduced since.

Wisconsin
AB 91, introduced by Rep. Spencer Black (D-Madison), would ban the use of cyanide in Wisconsin mines. Deferred to Committee of Natural Resources as of February 2003

AB 420 and SB 157, introduced by Rep. Terry McCormick (R-Appleton) and Judy Krawczyk (R-Green Bay), would mandate that mining operations receive no special treatment when compared with other Wisconsin industries. In other words, mines would not be exempted from regulations which are imposed on other activities in the state. AB 420 and S 157 have been in committee since June and May, respectively.
