This data frame contains summary statistics for EPA ratings collected in
many different data collection efforts. The function epa_subset() provides
functionality for easily filtering it in desired ways, and I recommend using
that function rather than working with this data frame directly.
Format
A data frame with 72951 rows and 25 variables:
- term

the term's type
