Description: This module downloads or reads cached EPA continuous emissions monitory system (CEMS) data to use with the ampd_plant_emissions.py module. Much of this module came from the Public Utility Data Liberation Project but was modified to pull the daily data which is recorded quarterly to minimize download times.

Functions:

  • build_cems_df: This is the only function intended to be directly used in this module. It will download or read cached CEMS data and return a dataframe with facility-level emissions.
