Manufacturers have been using DMS to electronically submit supporting certification documents to CARB since 2006. The system facilitates CARB’s ability to receive, organize, and track the review of manufacturers’ supporting certification documents, including durability plans, warranty statements, and alternative test procedures. Although DMS has been instrumental in the efficient submittal of documents by manufacturers and the tracking of the review process, it will be replaced by a new electronic document management system called CARB‑eFILE. CARB will discuss a tentative timeline on the transition from DMS to CARB‑eFILE, as well as demonstrate the new system and inform manufacturers of new system requirements.

The California Air Resources Board (CARB) is hosting a public workshop to update manufacturers on the development and deployment of a new electronic document management system to aid in the submission of mobile source emissions certification support documents. During the workshop, staff will present important user account changes, the procedure to obtain new accounts, and a tentative project timeline. Staff will also provide an overview of the new system and demonstrate the new process that manufacturers will need to follow to upload and submit documents into the new electronic document management system.

What is CARB DMS?
Manufacturers of new motor vehicles and engines must show compliance with the California emission requirements before they are legal for sale, use, or registration in the state. To show compliance, manufacturers must supply applications and supporting documents to the California Air Resources Board (CARB) for certification of their vehicles and engines. Traditionally, manufacturers have submitted these documents in paper format. They are reviewed by the certification staff and stored at CARB. To reduce the bulk of paper and facilitate the review of documents, CARB has introduced an electronic document management system (CARB DMS). It is an electronic system that allows manufacturers to send via the internet the certification documents to CARB. The CARB DMS collects the documents and routes them to staff for review. Manufacturers may track the progress of their certification and receive approval notification electronically.

Usage of the CARB DMS is required for all manufacturers seeking certification of new mobile source categories of motor vehicles and engines: passenger cars, light‑duty trucks, medium‑duty vehicles, on‑road and off‑road motorcycles, all‑terrain vehicles, on‑road heavy‑duty engines and vehicles, off‑road compression‑ignition engines, trailers, aerodynamic devices, zero‑emission powertrains, small off‑road engines, large spark‑ignition engines, and spark‑ignition marine engines.


CARB Electronic Certification Effort
The CARB DMS is one half of the electronic certification effort ongoing at CARB. The other half of the electronic certification effort is called E-Cert. The E‑Cert is the CARB companion product for the United States Environmental Protection Agency’s Engines and Vehicles Compliance Information System (EV‑CIS) project. This effort will allow manufacturers to submit data in an electronic database format called XML. The first two categories, motorcycle and light‑duty vehicles, have been developed and are operating. The subsequent categories will be implemented in a phased‑in approach one category at a time.
