See "Government Publications" under Websites.
Government documents in print would be referenced the same as online government documents, except you would not need to add a URL at the end of either the Full Note or the Bibliography reference.

Websites with information on using Chicago style:
This guide is intended to cover only the Notes and Bibliography system for citing sources.
For each type of source in this guide, both the general form and a specific example will be provided.
The following format will be used:
Full Note - use the first time that you cite a source.
Concise Note - use after the first time you cite a source.
Bibliography - use when you are compiling the Bibliography that appears at the end of your paper.
Information on citing and several of the examples were drawn from The Chicago Manual of Style (16th ed.).
Numbers in parentheses refer to specific sections and pages in the manual.
