Strategies Equipment Replacement Technical Considerations – Ensure technical feasibility. Strategy will involve carefully removing the original engine and replacing it with a newer-cleaner engine. Options for Implementation – Implementation through voluntary programs, incentives, lease renewals/renegotiations and/or contractual agreements. Pros and Cons – The purchase of newer construction equipment that meet cleaner on-road or off-road engine standards will demonstrate great emission reduction benefits. The challenge may be the availability of cleaner engines internationally.
Operational Improvements Technical Considerations – Ensure technical feasibility. Strategy will involve carefully removing the original engine and replacing it with a newer-cleaner engine. Options for Implementation – Implementation through voluntary programs, incentives, lease renewals/renegotiations and/or contractual agreements. Pros and Cons – As mentioned above, repowering older diesel engines with cleaner on-road or off-road engines can greatly improve emission reductions. However, international availability may be a concern.
Idle-Reduction Strategies Technical Considerations – Test feasibility of idle-reduction technology on construction equipment. Options for Implementation – Implement strategy through education and outreach, lease requirements, tariff charges, and incentives. Pros and Cons – Eliminating idling time by using an idle-reduction policies, education and technology greatly reduces emissions that would be generated from idling. International availability of technology tools such as on board computer systems with anti-idling settings may create a challenge for some ports. A major advantage of anti-idling programs for construction equipment is that they can save fuel costs with very little capital investment.
Cleaner Fuels Technical Considerations – Work with ports and fuel suppliers on the availability and supply of clean fuels. Depending on the type of clean fuel used, cleaning of the fuel tank may be required in order to avoid fuel contamination. Options for Implementation – Implementation strategies may include the use of lease requirements, tariff changes, or through contractual agreements. Pros and Cons – Positive emission reduction benefits for NOx, PM and GHGs. The use of biodiesel may present a slight increase in NOx. Challenges may arise with fuel availability and cost.
Emission Control Technologies Technical Considerations – Operational and feasibility testing is required to ensure the function and applicability of an emissions control technology on construction equipment. In particular, many ECTs require exhaust gas temperature analysis by conducting exhaust gas temperature datalogging to measure exhaust gas temperatures. Many ECTs have exhaust temperature thresholds that are required for the operation and effectiveness of the technology. Emission control technologies which have been certified or verified by regulatory agencies (such as those programs at the US Environmental Protection Agency and the California Air Resources Board) are most likely to deliver the claimed benefits. Options for Implementation – Implement strategy through lease requirements, tariff charges, incentives and/or contractual agreements. Pros and Cons – Applying ECTs has proved to have positive emission benefits in reducing particulate matter (PM), Oxides of Nitrogen (NOx), carbon monoxide (CO) and hydrocarbon (HC). Retrofitting construction equipment with ECTs can be challenging, careful evaluation and analysis is a must. |
