class SCC_ID

Bases: object

Use descriptions of SCC code levels to identify unit type and fuel type indicated by a complete SCC code (e.g., 30190003). The U.S. EPA uses Source Classification Codes (SCCs) to classify different types of activities that generate emissions. Each SCC represents a unique source category-specific process or function that emits air pollutants. The SCCs are used as a primary identifying data element in EPA’s WebFIRE (where SCCs are used to link emissions factors to an emission process), the National Emissions Inventory (NEI), and other EPA databases.

Eight digit SCC codes, such as ABBCCCDD, are structured as follows:

A: Level 1 BB: Level 2 CCC: Level 3 DD: Level 4

See SCC documentation for additional information: https://sor-scc-api.epa.gov/sccwebservices/sccsearch/docs/SCC-IntroToSCCs_2021.pdf

get_complete_scc()

Download full set of SCC codes from EPA and save to self._complete_scc_filepath. Note that downloading directly from website assignes filename for csv based as ‘SCCDownload-{y}-{md}-{t}.csv’

load_complete_scc()

Complete list of SCC codes (available from https://sor-scc-api.epa.gov/sccwebservices/sccsearch/) have been manually downloaded.

Returns:

all_scc

Return type:

pandas.DataFrame

static scc_query_split(scc)
