Contents Notes |
A presentation of the questions posed and an assessment of the issues related to the consideration of the amendment to delete deceleration testing from the medium and heavy truck noise regulation (40 CFR 205) is reported. Although noise emissions from engine brake operation are unique in character, it appears that noise control using engine exhaust muffling for the vehicle acceleration mode also reduces engine brake deceleration sound levels. Economic impacts of vehicle deceleration testing using engine brakes appear minimal if engine brakes are installed at the point of manufacture. The report contains EPA regulatory docket no. ONAC 77-3 exhibiting all comments submitted by interested parties. |
