HOUSTON (ICIS news)--US biosciences major Monsanto plans to open a new phosphorus mine in Idaho in 2010, the company said on Tuesday.

The US Bureau of Land Management (BLM) has begun the distribution of a draft environmental impact statement for the proposed mine that is located on 739 acres (299 ha) of land adjacent to other Monsanto phosphorus mines near Soda Springs, Idaho.

Monsanto-owned phosphorus mines and plants in Idaho are operated by a subsidiary, P4 Productions.

Monsanto produces phosphorus as a raw material for its Roundup herbicides.

A key environmental issue for the proposed mine is minimising the release of selenium from the operation.

Monsanto proposed covering selenium-bearing waste rock with a laminated geosynthetic clay liner that is said to be impervious to water.
