Emisstar continues to assist the New York City Department of Environmental Protection (DEP) in identifying and deploying emission control technologies (ECT) for nonroad, heavy duty construction equipment at the Croton Water Treatment Project in the Bronx, New York. This work is recognized as the first implementation of "Best Available Technology"(BAT) under New York City Local Law 77 and remains the paradigm for all other construction projects with stringent emission control requirements throughout the US for years to come.
ECTs deployed at Croton are either EPA or California Air Resources Board verified, in the process of receiving verification or are emerging technologies that hold promise in the construction sector. Final ECT selection depended on the outcome of Emisstar’s ECT Feasibility Evaluation and formal request for proposal process involving 16 potential technology suppliers. Other integral components of the project include on-site data collection and other analytical techniques to determine the applicability of each candidate ECT to the equipment over routinely encountered operating conditions. In-use emissions testing was conducted with Integrated Sampling Systems provided by testing partner Environment Canada.
As managing consultant to NYC DEP and URS Malcolm Pirnie on all emissions reduction activities, Emisstar’s contributions to the project include:
1. Final Project Workplan
2. Perform Fleet Survey, Inventory and Timeline Identification
3. ECT Feasibility Evaluation – Data Collection, Processing and Analysis
4. RFP Development & Issuance, Vendor Assessment, Economic Analysis
5. ECT Recommendation and Selection
6. ECT Design, Fabrication and Installation
7. Fuel and In-Use Emissions Testing
8. Training – Technicians and Operators
9. Communication and Outreach
10. Progress Reporting
11. Final Project Report
As part of the project, Emisstar works directly with emission control technology manufacturers and acts as an intermediary between these entities and the client. Additionally, Emisstar oversees fleet staff training and public outreach requirements as well as all periodic reporting functions. Croton is the first such project to demonstrate on-board, electrically regenerating active diesel particulate filters and mobile selective catalytic reduction/particulate traps in nonroad construction applications.
In all, some 40 machines are retrofitted with BAT Category I or higher ECT devices. A novel GPS-based remote data acquisition system, currently under research and development at Emisstar, is also being used to collect and evaluate real time engine and environmental performance data.
