Following are a set of P2 options you may wish to implement. No option is perfect for everyone, but sometimes options
that have worked at one facility can work at yours. They might also serve as inspiration.
Unreviewed VCM and EDC Options
Options below have not been reviewed by pollution prevention specialists. They are commonly recommended and
implemented for facilities.
Dirt and solids accumulate in the concrete lined trenches in the VCM and EDC process areas and periodically this must
be cleaned out and disposed of. This generates a hazardous waste, which must be incinerated and disposed. Also periodic
cleaning of the trenches can release contaminants to the air and contribute to personnel exposure. The accumulation
of dirt can be reduced or eliminated by installing a trench flush system that reuses cooling tower blowdown water
to flush the trenches once per week. This project has been determined to be economically and technically feasible.
