Exam route under review
Program authority: Water Treatment Facility Operators Board of Certification (WTFOCB), North Carolina Department of Environmental Quality
Local levels: Grade C-Surface, Grade B-Surface, Grade A-Surface; Grade D-Well, Grade C-Well, Grade B-Well, Grade A-Well.
Separate surface-water and well-water ladders, not a single four-class ladder. Official evidence establishes state administration, NC drinking-water-rule content and an examination designed for the applicant's local class, but does not explicitly identify standardized WPI/ABC, customized ABC, or independently state-developed examinations. No WPI class correspondence verified. Grade names come from the DEQ-linked 2018 rule compilation; current codification could not be extracted.
No state-matched course is linked for this stream yet.
Sections 90A-20.1 and 90A-21 identify the Water Treatment Facility Operators Board of Certification within DEQ; section 90A-24 assigns it certification requirements and examination procedures.
'The examinations are administered by the State'; exam subjects include 'North Carolina public drinking water rules.' These statements establish administration/content, not examination authorship or WPI standardization.
Rule .0201 lists C/B/A-Surface and D/C/B/A-Well with corresponding Board-approved schools; .0202 requires 'an examination designed for the class of certification for which the applicant is applying.'
Exam route under review
Program authority: Water Pollution Control System Operators Certification Commission (WPCSOCC), North Carolina Department of Environmental Quality
Local levels: Biological Grade 1 (WW1), Grade 2 (WW2), Grade 3 (WW3), Grade 4 (WW4); Physical/Chemical Grade 1 (PC1), Grade 2 (PC2). Additional ungraded specialties: Surface Irrigation (SI), Subsurface (SS), Land Application (LA).
Biological and physical/chemical certifications are distinct tracks; SI, SS and LA are additional specialties, not numbered biological grades. Official pages establish type-and-grade Needs to Know and Commission examinations, but do not explicitly establish standardized WPI/ABC scope, customized ABC use, or state examination authorship. Biological grades numbered 1-4 alone do not prove equivalence to WPI Classes I-IV. OIT is a certification status, not another grade.
No state-matched course is linked for this stream yet.
'The Water Pollution Control System Operators Certification Commission (WPCSOCC) is responsible for examination and certification'; certification requires an exam 'based on the Needs to Know for that type and grade of operator.'
Lists Biological WW1-WW4, Physical/Chemical PC1-PC2, LA, SI and SS separately; instructs LA/SI/SS applicants to choose N/A for grade. Links type/grade NTKs and states the supplied official math formula sheet is the only formula sheet usable at the exam.

Program authority: Water Treatment Facility Operators Board of Certification (WTFOCB), North Carolina Department of Environmental Quality
Local levels: Grade D-Distribution, Grade C-Distribution, Grade B-Distribution, Grade A-Distribution. Separate related certification: Grade Cross-Connection Control (CC), not a fifth distribution grade.
Distribution is explicitly addressed in the water-operator statute and rules; it is not inferred solely from treatment evidence. Rule .0206(c) requires certified distribution operators in responsible charge for community/non-transient non-community systems, subject to specified small-system exemptions and D-system alternatives. Standardized versus customized ABC versus state-developed exam remains unverified; D/C/B/A must not be translated into WPI I/II/III/IV without explicit correspondence.
No state-matched course is linked for this stream yet.
Section 90A-32 gives the Board authority over certification of personnel operating the distribution portion of a water treatment facility; the statute permits voluntary or mandatory programs, while the implementing rule specifies actual obligations.
Rule .0201(8)-(12) lists D/C/B/A-Distribution and separate Cross-Connection Control; .0206(c) specifies distribution ORC certification requirements and exceptions. C-Distribution and specified B-Distribution pathways require Board-approved trench-shoring training.
The state-administered exam subject list explicitly includes 'distribution system operation,' backflow prevention, hydraulics, pumping and storage; it does not identify a standardized WPI distribution exam.

Program authority: Water Pollution Control System Operators Certification Commission (WPCSOCC), North Carolina Department of Environmental Quality
Local levels: Collections Grade 1 (CS1), Grade 2 (CS2), Grade 3 (CS3), Grade 4 (CS4).
Collections is expressly listed as its own Commission certification and examination track, independently of drinking-water and wastewater-treatment evidence. Corresponding certification schools and progression requirements apply. No explicit standardized WPI/ABC collection-exam scope or CS-to-WPI class correspondence was found in the opened official sources; customized versus state-developed examinations likewise remain unverified.
No state-matched course is linked for this stream yet.
Identifies WPCSOCC as the examination/certification authority, separately lists COLLECTIONS (CS), and states exams follow the Needs to Know for each type and grade.
Explicitly lists Collections CS1, CS2, CS3 and CS4 and corresponding training-school requirements; cites eligibility rules 15A NCAC 08G .0401-.0409 and .0501.
Identifies 15A NCAC 08G operator requirements and separately links 'Collection Systems: 15A NCAC 02T .0300' under other regulations affecting operators.
