The document discusses Superfund sites and the process for evaluating and listing them. The EPA uses a Hazard Ranking System (HRS) to assess sites based on size, toxic materials, and hazard to human health. Sites that score above 28.5 are considered remedial sites and placed on the National Priorities List for long-term cleanup. Examples of remedial sites include landfills, dumps, and abandoned chemical plants. The document also lists links to pages about regulating the poultry industry and an animated documentary about algae-based biofuels.

- 14. Superfund Sites (red: currently on National Priority List; yellow: proposed; green: deleted from the list usually because it has been cleaned). The EPA checks out a site to see if it qualifies for Superfund. The EPA uses what it calls the Hazard Ranking System (HRS). The HRS is based on the size of the site, the toxic materials found there, and the site’s hazard to human health. The HRS assigns sites a score from 0-100. Most sites that score above a 28.5 are considered remedial sites. Remedial sites go on the National Priorities List (NPL), meaning they are scheduled for long-term cleanup. Landfills, dumps and abandoned chemical plants are examples of remedial sites.
