The document summarizes an EPA report on chemical releases within a 3 mile radius of an apartment complex located in zip code 97124. Ten facilities reported chemical releases, including ammonia, certain glycol ethers, copper, ethylene glycol, hydrogen fluoride, lead, methanol, nitrate compounds, nitric acid, N-methyl-2-pyrrolidone, and toluene. While most chemicals were treated on-site or transferred off-site for further treatment, higher than expected amounts of some chemicals like methanol were released into the air via fugitive emissions, posing some limited health risks to nearby residents.

10. The University of Tennessee's Center for Clean Products and Clean Technologies has developed a hazard evaluation system for TRI chemicals that produces separate rankings for ecological effects and human health effects, as well as a total hazard score that integrates information about a chemical's toxicity to humans and ecosystems with information about chemical characteristics that influence the likelihood of exposure to a substance. WHAT DO THE SCORES MEAN? UTN human health effects scores indicate how a chemical compares with others in terms of its capacity to harm human health. The graphic shows where a compound's hazard score falls relative to all chemicals that have been ranked using this system, indicating whether it is more or less hazardous than most chemicals. Chemicals that score at the far right end of the scale are significantly more hazardous (in the worst 10% of all chemicals according to this scoring system). All chemicals scored by a system have been placed in "bins" defined by percentiles (e.g., a chemical's score is in the least toxic 25% of chemicals scored by a system). The graphic illustrates which bin a chemical falls in according to each scoring system in Scorecard. Looking across these different systems, it is possible to identify chemicals that consistently score as high or low hazards, as well as chemicals that score high on some measures (such as human health hazards) but low on others (such as ecological hazards).
