Okay Solus, apology accepted.

"If the tailings are ultimately determined to be reactive, the company has proposed to line Cells 1E and 2E for the entire life of the operation to prevent reactive runoff from seeping into the ground and surrounding environment. Any discharge from the tailings basin would be monitored and if necessary, directed to a water treatment plant for appropriate treatment prior to discharge. Potential impacts and mitigation measures of this alternative will be included in the EIS." quote from EIS scoping

Again, In regards to the Draft EIS, my understanding is that the purpose of an EIS is to identify potential issues.  The permitting process would determine the ultimate design of project components.
