Regulatory Integrity Act of 2017 (Sec. 2) This bill directs each executive agency to make publicly available on the agency website or in the rulemaking docket on Regulations.gov a list of pending agency regulatory actions and for each such action: the date the agency began to develop or consider the action, its status, an estimate of the date it will be final and in effect, a brief description of such action, and a list of any applicable agency regulatory actions issued by the agency, or any other executive agency, that duplicate or overlap with the regulatory action; and a list of each public communication about the action issued by the agency, including the date of the communication, its intended audience, the method of communication, and a copy of the original communication. Each agency shall publish the information required within 24 hours after such communication is issued and maintain the public availability of such information for at least five years after the action is finalized. Any public communication issued by an agency that refers to a pending agency regulatory action shall specify whether the agency is considering alternatives and accepting comments and must expressly disclose that the agency is the source of the information to the intended recipients. Except for impartial communications that request comment on or provide information regarding the pending regulatory action, such a public communication referring to a pending action may not: (1) directly advocate, in support of or against the pending action, for the submission of information; (2) appeal to the public, or solicit a third party, to undertake such advocacy; or (3) be for publicity or propaganda purposes unless authorized by law. An agency that communicated about a pending agency regulatory action during the previous fiscal year shall submit to each congressional committee with jurisdiction over the agency's activities, by January 15 of each year, a report indicating: the number of pending agency regulatory actions the agency issued public communications about during that fiscal year, the average number of public communications issued by the agency for each such action, and the five pending actions with the highest number of public communications issued by the agency in that fiscal year and a copy of each such communication. The report shall be made publicly available on the agency's website.
