Editorial Standards

Source hierarchy

State statutes, regulations, issuing-program pages, forms, and exam bulletins control credential claims. EPA and the applicable NPDES authority control federal permit-program explanations. Training vendors and trade organizations add context but do not replace the authority.

Variable claims

Grade names, fees, exam rules, experience, OIT status, renewal cycles, contact hours, approved courses, reciprocity, and processing times require a current direct source. If that review is incomplete, the claim does not publish.

AI use

Software and AI may help organize research. They are not authorities. A cited source must be opened and the claim checked before publication. We do not create fictitious operators, experts, credentials, testimonials, or citations.

Commercial independence

Content must not imply a WastewaterPath product is required by a state or EPA. Paid material, when available, is independent study planning, not an official exam, certification, approved CEU course, or guarantee.

Corrections and retirement

Material errors are corrected promptly. Pages are retired when sources cannot support them or maintenance is not reliable. The original generated state pages were retired under this rule.
