What's New

  • On June 17, 2015, Caltrans Director Malcolm Dougherty signed the formal request to the FHWA for renewal of the 23 USC 327 NEPA Assignment MOU, pursuant to 23 CFR 773.115. Later this year, the FHWA will provide Federal Register notification, formally soliciting public comment. The renewal request letter can be found on the MOU page.
  • The Environmental Management Office (EMO) has updated and re-organized its internet pages. Please go to the EMO Homepage to see the changes.
  • The following forms have been updated to fix minor issues: HPSR, Supplemental HPSR, HPSR Narrative, and Supplemental HPSR Narrative forms.
  • Nepa Assignment program fact sheet has been updated to reflect time savings through March 31, 2015.
  • SER Chapter 11 has been completely revised and updated. Revisions include updated information on project-level PM analysis, clarification on when conformity is required for construction impacts, and more information on the use of the Air Quality Conformity Findings Checklist and conformity procedures under 23 USC 326 (CE Assignment) and 23 USC 327 (NEPA Assignment). In addition, a new Air Quality Conformity Analysis Cover Letter (sample) has been posted to the SER Forms and Templates page.
  • DEA has posted a new Sample Environmental Commitments Record (ECR) which can be found on the SER Forms and Templates page. This sample ECR has a new “field” for listing mitigation that is required for significant impacts under CEQA, which should be called out separately from other avoidance, minimization, and/or mitigation measures. Although Districts are free to continue using the form of their choice for recording environmental commitments, mitigation measures for significant impacts under CEQA need to be listed separately, regardless of the form that is used. Chapter 39 of the SER has also been updated.
  • Chapters 2 “State Requirements” and 28 “Cultural Resources” of the SER have been updated to include reference to Governor’s Executive Order B-10-11, the new PRC 5024 MOU, and to provide guidance on Assembly Bill 52 which amended CEQA to identify a “Tribal Cultural Resource” as a new, separate, and distinct resource to be analyzed under the California Environmental Quality Act (CEQA).
  • Volume 2 of the SER had been updated to reflect the new Memorandum of Understanding Between the California Department of Transportation and the California State Historic Preservation Officer Regarding Compliance with Public Resources Code 5024 and Governor's Executive Order W-26-92 (PRC 5024 MOU) that went into effect January 1, 2015.
  • SER Chapters 30 and 38 have been updated to be consistent with the new CE Checklist.
  • The Environmental Management Office has updated Chapter 23 (Farmlands) in Volume 1 of the SER.  It includes updated farmland definitions, an updated flow chart, more information on completing NRCS Forms CPA-106 and Form AD-1006, and additional information on Williamson Act coordination with the California Department of Conservation. Additionally, both the CPA-106 and the Form AD-1006 have been added to the SER Forms and Templates page.
  • The Environmental Management Office has updated the Air Quality Conformity Findings Checklist to include a hyperlink that provides additional information on applicable PM control measures and to clarify the conformity documentation required for the project file.
  • The Division of Environmental Analysis has updated the CTC Submittal page to provide updated instructions on CTC submittals when Caltrans is the CEQA Lead Agency and to provide the 2015 submittal due dates.
  • The Emergency Projects Environmental Process and Requirements Guidance has been updated to repair broken hyperlinks and to re-format the document.
  • The CE Checklist has been updated to include four new Categorical Exclusions under 23 CFR 771.117(c), three CEs that have been moved FROM the “d list” TO the “c list, and one new Categorical Exclusion under 23 CFR 771.117(d). These CEs are effective 11-05-2014.
  • The Division of Environmental Analysis (DEA) has developed the "Fact Sheet for New Categorical Exclusions under 23 CFR 771.117(c), CEs moved FROM the “d list” TO the “c list,” and Programmatic Agreements for CEs.”  These CEs are effective November 5, 2014.
