[Code of Federal Regulations] [Title 40, Volume 31] [Revised as of July 1, 2007] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR1068.445] [Page 846] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 1068_GENERAL COMPLIANCE PROVISIONS FOR NONROAD PROGRAMS--Table of Contents Subpart E_Selective Enforcement Auditing Sec. 1068.445 When may EPA revoke my certificate under this subpart and how may I sell these engines again? (a) We may revoke your certificate for an engine family in the following cases: (1) You do not meet the reporting requirements under this subpart. (2) Your engine family fails an SEA and your proposed remedy to address a suspended certificate is inadequate to solve the problem or requires you to change the engine's design or emission-control system. (b) To sell engines from an engine family with a revoked certificate of conformity, you must modify the engine family and then show it complies with the applicable requirements. (1) If we determine your proposed design change may not control emissions for the engine's full useful life, we will tell you within five working days after receiving your report. In this case we will decide whether production-line testing will be enough for us to evaluate the change or whether you need to do more testing. (2) Unless we require more testing, you may show compliance by testing production-line engines as described in this subpart. (3) We will issue a new or updated certificate of conformity when you have met these requirements. [67 FR 68347, Nov. 8, 2002, as amended at 69 FR 39270, June 29, 2004]
