Mobile Sources Forum: Offroad Diesel Retrofit Guidance Document

About the Guidance Document

The purpose of the WRAP Offroad Diesel Retrofit Guidance Document is to:

1. Provide guidance to WRAP members and other interested parties on the major elements needed to develop a well-structured retrofit program and program options for offroad engines,
2. Introduce a basic description of retrofit technologies and identify the factors to consider in evaluating and selecting retrofit strategies, and
3. Provide insights based on current program experience involving the application of retrofit technologies to offroad engines.

Volume 1 addresses the elements of structuring a retrofit program and is designed to assist those WRAP members and others involved in air quality program development.

Volume 2 contains a detailed description of retrofit technologies and experience. This volume is designed to provide more background information on retrofit strategies for air quality professionals, and to provide product users with a basic introduction on retrofit technologies and the current knowledge base regarding their use.

As used in the Guidance Document, the term “retrofit” is designed to encompass the full range of available strategies to reduce emissions from existing offroad diesel engines including technology-, fuel-, and operations-based approaches.

The Guidance Document will be updated periodically as new information becomes available. Updated sections will contain the date of the most recent revisions.
