Facilities having a rating of one through four points, inclusive,
do not require a certified operator. Classification of all other
facilities requires a comparable grade operator in responsible
charge.
Facilities having an activated sludge process will be assigned
a minimum classilicalion of Class 11.
Facilities having treatment processes for the removal of metal
or cyanide will be assigned a minimum classification of Class 11.
Facilities having treatment processes for the biological removal
of phosphorus will be assigned a minimum classification of Class
III.
In -plant processes and related control equipment which are an
integral pA, t of industrial production shall not be considered waste
treatment. Likewise, discharges of wastewater from residences
having a design flow of 1,000 gpd or less, shall not be subject to
rating.
