As part of the revised Wisconsin Administrative Rule NR 114, at least one operator shall be certified in the new collection system subclass.  For satellite collection systems the certification is voluntary, but highly recommended.  The collection system study guide and exam will tentatively be complete in 2018.  Collection system operators will have a permit term of five years to obtain collection system exam.  This new requirement was made in order to encourage the advancement of operator knowledge in operating and rehabilitating this aging infrastructure.
