S. Rept. 116-88: Early Participation in Regulations Act of 2019, Report to Accompany S. 1419, Including Cost Estimate of the Congressional Budget Office, September 10, 2019 [open pdf - 427KB]
From the Purpose and Summary: "The Early Participation in Regulations Act of 2019 requires Federal agencies to solicit and consider public comment early in the rulemaking process through an advanced notice of proposed rulemaking (ANPRM). Considering alternative solutions, articulated by or flowing from public comment at an earlier stage, ensures that agencies will consider a broader range of policies before they give preference to a particular position to the exclusion of others. The bill requires that for certain major rules, agencies must publish an ANPRM in the Federal Register at least 90 days before publishing a notice of proposed rulemaking (NPRM). The ANPRM must identify the nature and significance of the problem the agency seeks to address, the legal authority under which the agency may do so, generally describe regulatory alternatives under consideration, and solicit relevant data. The agency must then allow at least 30 days for public comment. [...] The bill does not require nor preclude agencies from responding to comments submitted under the ANPRM."
