Iowa Admin. Code r. 567-81.2 - General

(1) Plant classifications.
a. Plants with multiple treatment processes. A water treatment plant or wastewater treatment plant (hereafter noted as "plant") having a combination of treatment processes that are in different classifications shall be assigned the highest numerical plant classification of that combination.
b. Increase in classification for complex systems. The director may increase a plant or water distribution system classification above that indicated in 567-81.3 (455B) through 567-81.6 (455B) for those systems that, in the director's judgment, include unusually complex treatment processes, complex distribution systems, or present unusual operation or maintenance conditions.
(2) Operator certification.
a. Operator-in-charge (OIC). An OIC shall hold a certificate of the same classification of any plant or water distribution system under the OIC's control and of equal or higher grade than the grade designated for that plant or distribution system.
b. Shift operator. Any person who is responsible during an operating shift of a plant or distribution system or for major segment of a plant or distribution system and is under the supervision of the OIC identified in 81.2(2)"a" shall be certified in a grade no less than a Grade II for Grade III and IV plants and distribution systems and Grade I for Grade I and II plants and distribution systems.
(3) Public water supply system (PWS) certificates. A PWS certificate shall be issued as follows:
a. An operator successfully completing the water treatment certification shall be issued a PWS certificate valid for water treatment.
b. An operator successfully completing the water distribution certification shall be issued a PWS certificate valid for water distribution.
c. An operator successfully completing the requirements for both water treatment and water distribution certification shall be issued a dual PWS certificate valid for both classifications. For purposes of renewal of a dual certificate, all renewal fees and CEU requirements shall be applied as one certification. The number of CEUs required for renewal shall be determined by the highest certification grade on the dual PWS certificate.
(4) Owner notification and reporting.
a. A plant or distribution system owner shall notify the department of a change in the OIC(s) within 30 days after the change.
b. When requested by the department, a plant or distribution system owner shall report the method of treatment provided, the average daily pumpage, and the name(s) of the OIC(s).
(5) Operator notification. Certified operators shall notify the department of a change in address or employment within 30 days after the change.
(6) Compliance plan. When the director allows the owner of a plant or distribution system required to have a certified operator time to obtain an operator, the owner shall submit a compliance plan to the department indicating what action will be taken to obtain a certified operator. The plan shall be on a form provided by the department and shall be submitted within 30 days of the owner's receipt of a notice of violation for not having a properly certified operator.
