Portable Diesel Engine ATCM - Fleet Reporting

This page last updated December 17, 2014

These reports are for Portable Equipment, not Off-road mobile equipment.  

The fleet reporting tools below can be used to determine the average PM emission rate for the engines in your fleet.

Each report includes printable pages and a compliance statement page which can be mailed to the Air Resources Board.
The report tools also allow you to experiment with different turnover, repower, and retrofit strategies to plan for compliance with the Portable Diesel Engine ATCM.

Be advised that we are providing the reporting tools as a convenience.  The ultimate responsibility for accuracy and compliance is yours.

If you encounter any problems with the reporting tools or have any questions or comments, please call the ARB staff listed below.

The fleet recordkeeping and reporting requirements are found in the Portable Diesel Engine ATCM, Section 93116.4
