Congressional Budget Office Cost Estimate: S. 577: Providing Accountability Through Transparency Act of 2017 [open pdf - 12KB]
"S. 577 would require agencies to post the Internet address of the website (regulations.gov), which would contain a summary of every rule the agencies propose. Under the bill, those summaries could not exceed 100 words in length. Executive Orders 12866, 13563, and the June 1, 1998, Presidential Memorandum on Plain Language require agencies to use plain language in all proposed and final rules. Thus, CBO [Congressional Budget Office] expects that preparing the short summary of proposed rules under S. 577 would have no significant cost. Enacting the bill would affect direct spending by agencies not funded through annual appropriations; therefore, pay-as-you-go procedures apply. CBO estimates, however, that any net increase in spending by those agencies would not be significant. Enacting S. 577 would not affect revenues. CBO estimates that enacting S. 577 would not increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2028."
