What do I need to do to comply with EPA standards?
If you have access to a sanitary sewer you have the option of using a discharge system. Our system is meant to remove constituents down to a reading that should be acceptable to local parameters. (Parameter settings are not the same everywhere. Check with your local municipality)
If you don't have access to a sanitary sewer, you will then need a closed loop system that removes constituents so the water is recycled for pressure washing.
