I'm not from usa, but EU. Here, mining operations, quarries, etc. get "booms will be here" licences, with limits (when (usually only daytime), where (quarry/mine limits and how strong the 'booms' are). So for those (rutine, standard blasts), our enviromental (earthquake) agencies don't get the data for each blast (they eg. get data, that company XYZ is allowed to do blasts up to ABC power (KJ or whatever) in location DEF, from 1. jan 2020 to 31. dec 2020 when they have to renew their licence).

That level of permitting at least let's environmental agencies get data after the fact. If they can get the place and time range of blasts they can filter that out of their measurements. It's probably some poor intern's job. Go through a stack of permits and mark measurements likely covered by the permitted blasting.
