In the Solar PEIS, the BLM committed to preparing solar regional mitigation strategies (SRMSs) for the solar energy zones (SEZs). These regional mitigation strategies were intended to simplify and improve the mitigation process for future solar projects in SEZs.
In January 2017, the BLM released the Regional Mitigation Strategy for the Colorado Solar Energy Zones – Final Report (PDF, 26.1 MB). This document addresses regional mitigation for the De Tilla Gulch SEZ and two other SEZs in Colorado's San Luis Valley. Additional supporting studies were released with the Regional Mitigation Strategy; all the documents are available through the BLM's Renewable Energy Mitigation webpage.
With IM-2019-018, the BLM established policy that compensatory mitigation could not be required as a condition for project approvals. However, with the issuance of IM 2021-038 on July 14, 2021, the BLM rescinded the previous IM-2019-018. The BLM expects to establish policies which are aligned with EO 13990, SO 3398, and the priorities of the Department. During this interim period offices should consider and implement compensatory mitigation on a case-by-case basis, in consultation with state office and national office program specialists and the Office of the Solicitor as needed.
