Find EPA-regulated facilities in FRS by NAICS code (industrial category)
Source:R/latlon_from_naics.R
latlon_from_naics.RdGet lat lon, Registry ID, given NAICS industry code(s) Find all EPA Facility Registry Service (FRS) sites with this/these NAICS code(s)
Arguments
- naics
a vector of naics codes or query of titles of NAICS, or a data.table with column named code, as with output of
naics_from_any()- children
optional logical. set to FALSE to get only exact matches rather than all facilities whose NAICS starts with provided naics (or naics based on provided title). Many facilities have only a longer more specific NAICS code listed in the FRS, such as a 6-digit code, so if the category (e.g., 4-digit) is queried then without children = TRUE one would not find all the sites within that overall category.
- id_only
optional logical. Must set TRUE to get only regid instead of table
- ...
passed to
naics_from_any()
Value
A data.table (not just data.frame) with columns called lat, lon, REGISTRY_ID, NAICS, naics_found, naics_query (unless id_only parameter set TRUE). naics_query is the input parameter that was used (that had been provided to this function as naics). naics_found and NAICS are identical (redundant), and are the code found that was listed in the frs_by_naics table, so it might be a subcategory (child) of the naics_query term. For example, naics_query might be 33611 (5 digits) and for one facility the NAICS and naics_found might be 336111 (a 6-digit code) and for another facility they might be 336112.
Details
Important notes:
Finding the right NAICS and finding all the right sites by NAICS is complicated, and requires understanding the NAICS codes system, the FRS data, and the EJAM functions. See the discussion in the "Advanced" or other vignettes/articles.
Many FRS sites lack NAICS code!
Note the difference between children = TRUE and children = FALSE
The NAICS in the returned table may be a child NAICS not the NAICS used in the query! This may cause confusion if you are querying multiple parent NAICS and you want to analyze results by NAICS!
The functions like regid_from_naics(), latlon_from_naics(), and frs_from_naics()
try to find EPA FRS sites based on naics codes or titles.
EPA also provides a FRS Facility Industrial Classification Search tool where you can find facilities based on NAICS or SIC.
