the epa is like a little cock roach problem ... i got them at or near my shop 2 the 3 times a week .... there were old tanks that leaked when it was a gas station and the creek next to it got most of the run off .... i just bought the place so i am no hurry to see if it was done right ,,,,, i had to set up my paint booth so it was to there liking and the filter set up is not like any i see before... i use hvlp guns i don't need any thing like it
