  2. Topics For Discussion Today • Introduction dates for Tier 4 Interim (T4I) and Tier 4 Final (T4F). • Tier 4 “Compliant” is not the same as Tier 4 “Certified”. • Know the difference. • Project Owners are driving early introduction of Tier 4 Equipment. • Your projected equipment life expectancy doesn’t count.

  3. Introduction Dates for Tier 4 Interim (T4I) and Tier 4 Final (T4F)

  4. Exhaust After Treatment Required EPA Non-Road Emission Regulations

  5. T4I / T4F Availability

  6. T4I/T4F Emission Standards(175-750 hp)

  7. T4F Emission Reductions • Comparison of Tier 1 Emission Standards to Tier 4 Final Emission Standards.

  8. T4I / T4F Availability • Implications for transition from T4I to T4F: • T4F will become Best Available Control Technology (BACT), restricting the ability to get air quality permits for portable equipment and stationary engines. • Generally, permitting requirements don’t impact off-road self-propelled equipment. • Local construction policies will shift to Tier 4.

  9. Transition to Tier 4 • Excerpt from LA County Metro’s Green Construction Policy.

  10. Tier 4 “Compliant” is not the same as Tier 4 “Certified”

  11. Certified vs. Compliant • Engine Certifications. • Engine Certifications are obtained by the manufacturer. • An In-Use engine cannot be re-certified to a higher tier level. • “Flex” or “Transition” Engines. • These are lower-tier engines which EPA and CARB allow to be installed in a current model year machine.

  12. Certified vs. Compliant • A Tier 4 “Certified” engine meets the Tier 4 Emission Standards. • A Tier 4 “Compliant” engines satisfies EPA’s phase in allowance, and; • Is legal to sell in the United States, and; • Is legal to operate in the United States, but; • Is not certified to the Tier 4 Emission Standards (it’s likely Tier 3).

  13. Certified vs. Compliant • Purpose is to prevent product availability disruptions when the tier standards change. • Allowances to produce these engines are provided to manufacturers based on their sales history. • Special labels are affixed to these engines that reference the flex provisions. • Indicated by the reference to 40 CFR 1039.625 and 13 CCR 2423(d) on the engine emissions label.

  14. Compliant Engine Labels

  15. Project Owners are Driving Early Introduction of Tier 4 Equipment

  16. Early Introduction of Tier 4 Equipment • These Permit Conditions are from a Permit issued by EPA Region 1. These conditions generally require the use of Tier 2 and Tier 3 Engines. However…

  17. Early Introduction of Tier 4 Equipment • The 226 ton NOX limit was not attainable using Tier 2 and Tier 3 equipment. • The project owner requested that the Contractor use certified Tier 4 final equipment to maintain compliance with the 226 ton NOX limit.
