Answer:

<em>CERCLA set up a trust fund to fund both cleanup and enforcement actions. Sometimes, the fund is called the Superfund.</em>

Explanation:

<em>On December 11, 1980, Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund.</em>

The law passed a tax on both the chemicals and petroleum industries which established wide Federal power to respond directly to leaks or potential releases of hazardous materials that could threaten public health or the atmosphere.

$1.6 billion was collected over five years, and also the tax went to a trust fund to clean up hazardous waste sites that had been neglected or unregulated.

Short description

The Millennium Project (MP) is integrating all of its information, groups, and software into a “Global Futures Intelligence System” (GFIS). GFIS is The Millennium Project’s new way for you to participate with and have access to all of our resources in one place. Those who buy a one-year subscription can interact with all the elements of the system, make suggestions, initiate discussions with experts around the world, and search through over 10,000 pages of futures research and 1,300 pages of methods. The text has built-in Google translation with 52 languages. MP Node chairs and content reviewers will have free access.

Instead of publishing the State of the Future once a year, the material is being updated in the Global Futures Intelligence System on a continual basis – the same is true with Futures Research Methodology – you do not have to wait five or so years to get a new version. Some Real-Time Delphi studies and other research are also being made available as soon as they are completed, and will be accessible for discussion of conclusions.

The GFIS is not just new software, vast information, and global experts; it is also a system to produce synergies among these three elements for greater intelligence than their separate values. It is rather a global intelligence utility from which governments, UN agencies, businesses, NGOs, universities, media, and consultants can draw different values. The GFIS staff is more interested in synergistic intelligence than competitive intelligence, and how the world can work for all, not just for a single nation, ideology, or issue. It can provide decision makers, advisors, and educators with insights that reflect the consensus and/or range of views on the important issues of our time. The engagement of the user with our information, participants, and software is intended to help humanity become more proactive.
