We may also specify individual configurations.\n(2) The engine/equipment assembly plant, storage facility, or (if you import the engines/equipment) port facility from which you must select engines/equipment.\n(3) The procedure for selecting engines/equipment for testing, including a selection rate.\n(4) The test procedures, duty cycles, and test points, as appropriate, for testing the engines/equipment to show that they meet emission standards.\n(b) We may state that we will select the test engines/equipment.\n(c) We may identify alternate families or configurations for testing in case we determine the intended engines/equipment are not available for testing or if you do not produce enough engines/equipment to meet the minimum rate for selecting test engines/equipment.\n(d) We may include other directions or information in the test order.\n(e) We may ask you to show us that you meet any additional requirements that apply to your engines/equipment (closed crankcases, for example).\n(f) In anticipation of a potential audit, you may give us a list of your preferred families and the corresponding assembly plants, storage facilities, or (if you import the engines/equipment) port facilities from which we should select engines/equipment for testing. The information would apply only for a single model year so it would be best to include this information in your application for certification. If you give us this list before we issue a test order, we will consider your recommendations, but we may select different engines/equipment.\n(g) If you also do routine production-line testing with the selected family in the same time period, the test order will tell you what changes you might need to make in your production-line testing schedule.","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER U—AIR POLLUTION CONTROLS","PART 1068—GENERAL COMPLIANCE PROVISIONS FOR HIGHWAY, STATIONARY, AND NONROAD PROGRAMS","Subpart E—Selective Enforcement Auditing"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-40.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:04Z","sha256":"884c027e5eb200d0f4d26f112f23f38412b1538b271c3013dc411457adb63287","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-1068.401","next":"us/40-cfr-1068.410"},"notice":"GroundRules: Original legal text.
