I am looking for some insight into our Environmental Monitoring program. We are a very low risk product and currently do only monthly swabbing. We do Zones 1-5 and one of our swabs is a drain that goes off of a boiler relief discharge. It is the only drain swab that we have in our program because we do not put anything down our drain since the nature of the product we deal with would clog our drains.
So I am wondering if we even need to have this drain swab in our program because it is located in our utility room and has nothing to do with the product we work with?
Any insight on this would be very much appreciated!
