In implementing the RPA it is clearly understood that not everything can be done all at once. As such, a phased approach will be used. The initial phase focuses on POPs and heavy metals which present a major pollution threat to the arctic marine environment. In subsequent phases the RPA will be expanded to address other contaminants and activities which destroy or degrade the arctic marine and coastal environment.
Costs are always an important consideration.
The RPA is based on existing resources and programs. It also acknowledges that concrete steps to remediate major pollution sources in the Russian Federation will require major investments.
