Environmental cleanup law: Environmental cleanup laws<section begin=overview /> govern the removal of pollution or contaminants from environmental media such as soil, sediment, surface water, or ground water.  Unlike pollution control laws, cleanup laws are designed to respond after-the-fact to environmental contamination, and consequently must often define not only the necessary response actions, but also the parties who may be responsible for undertaking (or paying for) such actions.  Regulatory requirements may include rules for emergency response, liability allocation, site assessment, remedial investigation, feasibility studies, remedial action, post-remedial monitoring, and site reuse. <section end=overview />

Colomac Mine: The Colomac Mine was a privately owned and operated open pit gold mine located 220 km northwest of Yellowknife in the Northwest Territories in Canada .  The Colomac mine operated between 1990–1992, and 1994–1997.  It was operated by Neptune Resources Limited that had little success in making a profit during its operation.

Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy.  The Federal Government of Canada became owners of the mine, along with the related environmental issues.

Multilateral Environment Agreement: A Multilateral Environmental Agreement (MEA) is a legally constructed agreement between multiple nations, which allows for the countries to reach an environmental goal.  MEAs are essential within creating environmental policies, as they are difficult to implement, and sustain.  These agreements are constructed in order to ensure environmental sustainability for the future, and allow for major environmental issues to be tackled.  This will occur by using more than one major contributor and/or country to the issue.  MEAs are tactics used in order to directly combat a set of issues as a group of nations, and as a united front.  MEAs are important when it comes to international politics, while dealing with such serious issues, as well as the future of global environmental sustainability as a whole.
