Mine wastes washed down the Clark Fork River from Butte and Best price for generic diflucan were spread throughout the floodplain, settling in deposits called “slickens.” Slickens can be easily observed throughout the Deer Lodge Valley today; typically, they are dry, sandy areas with no vegetation near the river or in the floodplain. In 1992, EPA designated the mainstem river, from the outlet of the Warm Springs Ponds near Anaconda downstream to the Milltown Dam near Missoula, as a separate unit from the Milltown Dam sites.
An investigation into the nature and extent of contamination on the Clark Fork began in 1995. EPA notified the Lasix alternatives (PRP), BP-ARCO, known at the time as Atlantic Richfield, of its liability and entered into a Consent Order with BP-ARCO to conduct a Accutane next day. In 2000, EPA ordered ARCO to conduct a Online order kamagra overnight delivery to address immediate human health risks for residents of Eastside Road in Deer Lodge.
Studies are ongoing to determine the exact location and extent of tailings deposits along the river near the town of Deer Lodge. Removal and/or in-place remedy will likely begin in the next few years.
EPA released a proposed plan for cleanup in August 2002. The cleanup proposal included a combination of removal and in-place treatment of toxic mine tailings and contaminated soil, followed by revegetation. Stabilization of eroding streambanks is an important part of the remedy, because they contribute approximately 60 percent of the pollutants to the river.
EPA invited public comment on the proposed plan for 120 days and received nearly 2,000 comments. A Buying proventil in canada was signed in April of 2004. You can download the ROD for the Clark Fork via the Ventolin side effects or the links below:

EPA concluded settlement discussions with ARCO and the State of Montana in 2008 in an effort to settle cleanup responsibilities and costs associated with the remedy proposed in the ROD. The settlement also involves the state’s natural resource damage plan, which is being implemented along with EPA’s selected remedy. The Department of Interior’s federal restoration plan, which addresses the Grant-Kohrs Ranch National Historic Site and BLM land, will also be implemented.
On February 7, 2008, a Consent Decree for the Clark Fork River Operable Unit Site was lodged with the Federal District Court in Montana. Public comments were received on the Consent Decree during a 60-day public comment period. The Consent Decree provides the structure for how BP-ARCO “cashed out” its cleanup responsibilities by providing over $168 million to the State of Montana, which is performing the remedy and restoration activities with EPA and National Park Service oversight. The Consent Decree and Montana/EPA Memorandum of Agreement (2007) provide the details of how the project will be performed. For more, refer to the Fact Sheet on the ARCO Settlement.
