DOORS

Most CARB staff are currently working remotely. At this time, DOORS online reporting, along with assistance with reporting through email and the DOORS Hotline will continue operating as normal. However, processing of paper forms received by mail or fax will be limited. We highly encourage you to submit any paper forms by scanning or taking a photograph, and then sending it by email to doors@arb.ca.gov. Thank you for your understanding.
