As a retired member of that dreaded bunch of goverment contractors, I many times felt stupid that I could not throw away empty sand bags without washing first to get rid of silica dust. Empty quart oil cans in the trash were a serious no-no. We were not even allowed to wash a vehicle in an area without a waste water treatment equipped drain. Brent, you got a waste water treatment plant in your driveway for those phosphates in your car soap?
