The Air Resources Board adopted a regulation on the Commercialization of Alternative Diesel Fuels (ADF), found at California Code of Regulations (CCR), title 13, sections 2293-2293.9 (ADF regulation), which became effective January 1, 2016. The regulation establishes a comprehensive, multi-stage process governing the commercialization of new ADFs in California. The regulation also establishes specifications and in-use requirements (such as using a NOx reduction additive) for biodiesel, as the first ADF subject to the ADF regulation.
These documents are intended to assist regulated parties with complying with the ADF regulation reporting and recordkeeping requirements.
