Official English notes
8-13-09 - The 4-2-91 entry "oil well fracturing" was changed to more accurately describe the service and transfer it from Class 40. The service is not material treatment, but rather the breakdown of geological formations and such an activity is more appropriate in Class 37 with other mining services.
