Which of the following provides detailed requirements that support the intent of a regulation presented in a Part, but gain the force and effect of the governing regulations only if specifically referred to in the governing regulation?

The concept of "Implementing Standards" refers to detailed requirements or specifications that provide clarity and support the intent of a broader regulation found within a specific Part. These standards are crucial because they translate the general principles of the governing regulation into actionable guidelines. However, their enforceability is contingent upon them being explicitly referenced within that governing regulation; without such a reference, they do not carry legal weight.

This means that while the regulations lay out the framework and expectations, it is the Implementing Standards that deliver the specifics necessary for compliance and operational effectiveness. They basically serve as a bridge between the abstract directives of regulations and practical application.

Other options, such as Standard Operating Procedures or Operations Specifications, are typically internal instructions or specific guidelines that may not necessarily have the same level of regulatory impact unless aligned with the governing regulation. Implementing Rules and Regulations, though similar, often pertain to the initial establishment or clarification of the regulations themselves rather than distilling them into detailed standards. Thus, Implementing Standards is the most precise choice to describe the requirements defined within the context of existing regulations that require explicit citation for enforceability.
