Exam route under review
Program authority: North Dakota Department of Environmental Quality, Division of Municipal Facilities - Operator Certification and Training
Local levels: Grade IA, Grade I, Grade II, Grade III, Grade IV; corresponding facility Classes IA, I, II, III, IV.
Certification and local grades are verified. The July 2026 report documents North Dakota's exam-review process and state-administered examinations, but does not explicitly identify the current exam bank as state-specific, standardized WPI/ABC, or customized ABC. Its appended September 2025 minutes describe ABC testing exploration as ongoing; third-party examination authority/planning is not proof of adoption. No local-grade-to-WPI-class correspondence established.
No state-matched course is linked for this stream yet.
Pages 6–7: a North Dakota group evaluates exam changes and validates questions; NDDEQ staff conducted examinations. Page 40: 'Exploration of ABC testing – Ongoing.' Page 42 discusses a move to third-party examination services without identifying an adopted exam product.
Section 11 establishes five operator grades for each of the four streams; section 12 names Grade IA, I, II, III and IV. Section 05 requires separate examinations for each facility/system classification, but names no exam bank.

Program authority: North Dakota Department of Environmental Quality, Division of Municipal Facilities - Operator Certification and Training
Local levels: Grade IA, Grade I, Grade II, Grade III, Grade IV; corresponding wastewater-treatment facility Classes IA, I, II, III, IV.
Wastewater treatment is independently confirmed, not inferred from drinking-water exam evidence. State-issued study outlines exist, but neither they nor current rules explicitly establish the current exam bank as standardized WPI/ABC, customized ABC, or exclusively state-written. Grade IA nonmechanical facilities under 500 population equivalent are exempt from mandatory certification; certification remains available voluntarily.
No state-matched course is linked for this stream yet.
Section 09 separately classifies wastewater-treatment facilities IA–IV, with IA covering nonmechanical treatment under 500 population equivalent. Sections 11–12 establish five grades; section 05 requires separate classification examinations without identifying their bank.
Dated 12/15/2020: 'The outlined topics indicate the general subjects which are the basis for examination questions.' Includes treatment processes, sampling, safety, NPDES permit stipulations and recordkeeping; does not identify WPI/ABC exams.
Names NDDEQ Division of Municipal Facilities as implementing authority. Wastewater section exempts stabilization ponds/other nonmechanical treatment serving fewer than 500 population equivalent and says operators can choose to become certified.

Program authority: North Dakota Department of Environmental Quality, Division of Municipal Facilities - Operator Certification and Training
Local levels: Grade IA, Grade I, Grade II, Grade III, Grade IV; corresponding distribution-and-storage Classes IA, I, II, III, IV. A restricted water distribution 1A certificate is an alternative IA pathway, not a sixth regular grade.
The alternative IA open-book booklet is explicitly a North Dakota, system-specific pathway. The ordinary IA–IV exam-bank identity remains unverified, so the whole stream cannot safely be labeled standardized, customized, or wholly state-specific. No WPI class mapping verified.
No state-matched course is linked for this stream yet.
Page 8 describes an EPA-approved open-book exam booklet for distribution systems under 500: returned to the Department for grading, yielding a six-month restricted distribution 1A certificate limited to the operator's system; after satisfying experience, a standard 1A certificate is issued. Pages 7 and 40 document local exam review and ongoing ABC exploration, not standardized adoption.
Section 08.1 names distribution-and-storage Classes IA, I, II, III and IV; sections 11–12 establish and name the five operator grades. Section 05 permits department-designated third-party grading but identifies no provider or standardized exam.

Program authority: North Dakota Department of Environmental Quality, Division of Municipal Facilities - Operator Certification and Training
Local levels: Grade IA, Grade I, Grade II, Grade III, Grade IV; corresponding wastewater-collection-and-transfer Classes IA, I, II, III, IV.
Collection certification and its five grades are independently verified. The collection-specific state study guide identifies examination subjects but not the current question-bank supplier or standardized/customized status. Collection systems below 500 population equivalent are exempt from mandatory certification under NDCC 23.1-07-07; the IA certification route is nevertheless offered. No WPI correspondence verified.
No state-matched course is linked for this stream yet.
Section 09.1 explicitly names collection-and-transfer Classes IA, I, II, III and IV; IA serves fewer than 500 persons. Sections 11–12 establish the same five operator grades; section 05 names no exam bank.
Dated 12/15/2020: outline subjects are 'the basis for examination questions.' Includes sewer hydraulics, design/installation, lift stations, safety, plans/specifications and Recommended Standards for Sewage Works; no standardized WPI/ABC scope stated.
Appendix E reproduces NDCC 23.1-07-07: operators of wastewater collection systems and nonmechanical wastewater treatment serving fewer than 500 population equivalent are excluded from mandatory certification. NDCC 23.1-07-06 authorizes department or third-party exam preparation but does not identify an adopted exam product.
Dedicated prep is not available or being sold yet.
