SUPPLEMENTARY INFORMATION:

Pursuant to 23 U.S.C. 327 (Section 327), the California High-Speed Rail Authority (CHSRA or Authority) has assumed FRA's environmental review responsibilities under the National Environmental Policy Act (NEPA; 42 U.S.C. 4321 et seq.). However, under Section 327, FRA remains responsible for compliance with the Clean Air Act General Conformity requirements. In compliance with NEPA and the California Environmental Quality Act (CEQA), the Authority published a Final Environmental Impact Record/Final Environmental Impact Statement (EIR/EIS) for the Burbank to Los Angeles Section of the California High-Speed Rail (HSR) System on November 5, 2021. The Final EIR/EIS is available at https://hsr.ca.gov/​programs/​environmental-planning/​project-section-environmental-documents-tier-2/​burbank-to-los-angeles-project-section-draft-environmental-impact-report-environmental-impact-statement/​.

FRA prepared a Draft General Conformity Determination, pursuant to 40 CFR part 93, subpart B, which establishes the process for complying with the General Conformity requirements of the Clean Air Act. FRA published a notice in the Federal Register on September 20, 2021 advising the public of the availability of the Draft Conformity Determination for a 30-day review and comment period. The Draft Conformity Determination was published at https://www.regulations.gov, Docket No. FRA-2021-0082. The comment period of the Draft Conformity Determination closed on October 20, 2021. FRA received one comment expressing support for the project and Draft General Conformity Determination.

FRA prepared the Final General Conformity Determination pursuant to 40 CFR part 93, subpart B, and based on the Authority's coordination with the U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and the South Coast Air Quality Management District (SCAQMD). The analysis found that construction period emissions would exceed the General Conformity de minimis threshold for Nitrogen Oxides (NO_X). However, operation of the Project would result in an overall reduction of regional emissions of all applicable air pollutants and would not cause a localized exceedance of an air quality standard. Consistent with the General Conformity Rule, the Authority will ensure all remaining emissions that exceed the de minimis thresholds, after implementation of the impact avoidance and minimization features and onsite mitigation measures, will be offset through an agreement with SCAQMD. The Authority and SCAQMD will enter into an agreement after receipt of construction funding but prior to the start of construction. Based on this commitment, FRA determined the Project will conform to the requirements in the approved State Implementation Plan.

The Final General Conformity Determination is available at https://www.regulations.gov, Docket No. FRA-2021-0082, and FRA's website at https://railroads.dot.gov/​environment/​environmental-reviews/​clean-air-act-california-general-conformity-determinations.
