Status message

There are 3 Updates appearing in the Federal Register for 40 CFR 80. View below or at eCFR (GPOAccess)
§ 80.50 General test procedure requirements for augmentation of the emission models.
(a) The following test procedure must be followed when testing to augment the complex emission model described at § 80.45.
(1) VOC, NOX, CO, and CO2 emissions must be measured for all fuel-vehicle combinations tested.
(2) Toxics emissions must be measured when testing the extension fuels per the requirements of § 80.49(b) or when testing addition fuels 1, 2, or 3 per the requirements of § 80.49(a).
(3) When testing addition fuels 4, 5, 6, and 7 per the requirements of § 80.49(a), toxics emissions need not be measured. However, EPA reserves the right to require the inclusion of such measurements in the test program prior to approval of the test program if evidence exists which suggests that adverse interactive effects of the parameter in question may exist for toxics emissions.
(b) The general requirements per 40 CFR 86.130-96 shall be met.
(c) The engine starting and restarting procedures per 40 CFR 86.136-90 shall be followed.
(d) Except as provided for at § 80.59, general preparation of vehicles being tested shall follow procedures detailed in 40 CFR 86.130-96 and 86.131-96.
