Who

Names, permit and licence numbers are from the restricted materials permit(s) the use reports were filed under. Individual QAL and RPF numbers are linked to the named person using official DPR and Board of Forestry rosters; the roster date is shown when historical and does not establish current renewal status. Websites, phone numbers and email addresses are from each company's own website, shown once the site has been confirmed as the right business.

Where

The property inside these sections has not been identified yet, so the map shows the reported public-land-survey section H18N04E01. A section is one square mile and is where the application was reported, not the area treated.
