Guidance documents cannot create binding requirements that do not already exist by statute or regulation. Accordingly, the Department may not use its enforcement authority to convert agency guidance documents into binding rules. Likewise, enforcement attorneys may not use noncompliance with guidance documents as a basis for proving violations of applicable law. Guidance documents can do no more, with respect to prohibition of conduct, than articulate the agency or Department's understanding of how a statute or regulation applies to particular circumstances. The Department may cite a guidance document to convey this understanding in an administrative enforcement action or adjudication only if it has notified the public of such document in advance through publication in the Federal Register or on the Department's website. Additional procedures related to guidance documents are contained in part 5, subpart C, of this chapter.
