Estimated PM2.5 Emissions from Port Operations in Philadelphia

1 Estimated PM2.5 Emissions from Port Operations in Philadelphia Tom Weir City of Philadelphia, Department of Public Health, Air Management Services Contracted work by EC/R Incorporated for U.S. EPA, Region III October 2005 October Port PM2 5 presentation5 ppt

2 Why is there interest in the Port? Philadelphia has been designated as nonattainment for fine particulate matter (PM 2.5) Diesel emissions make up a substantial amount of PM 2.5 Diesel particulate emissions are an important part of EPA s Integrated Urban Strategy under the National Air Toxics Program Recent studies indicate that the Port is an important contributor to these emissions

3 Purpose for Study Improve the quality of the emission inventory for Philadelphia s Port Emission inventories are a basic piece of information needed to help identify reasonable strategies to improve conditions

4 Steps Taken Information is from the contractor s final report -Results being evaluated Evaluated diesel particulate emissions for the Port of Philadelphia Marine Vessels Land-based Operations Assessed the validity of assumptions used in the national inventory

5 Port of Philadelphia

6 Emission Inventory EPA produces a National Emissions Inventory (NEI) Emissions from marine vessels are estimated for the entire country then allocated to major ports based on cargo throughput Land-based cargo handling generally falls into the NEI category of diesel construction and mining equipment.

7 Contractor Study, Activity-Based Estimates for Marine Vessels 44 tons/year Oceangoing vessels account for the highest emissions at 30.9 tons/year Tugs and Ferries - 13 tons/year Estimates are much lower than the 1999 NEI

8 1999 NEI Emission Estimates for Land-Based Cargo Handling Equipment Cranes, Top loaders, Forklifts, etc. Allocated 138 tons/year from diesel construction and mining equipment in the City NEI does not explicitly estimate emissions from land-based cargo handling at port facilities

9 Contractor Study, Activity-Based Estimates for Land-Based Cargo Handling Equipment 64 tons/year almost half of the emissions estimated in NEA for construction and mining 22% of total diesel particulate for the City Contractor and NEI estimates for Land-Based equipment appear compatible

10 Commercial vessels NEI may have overestimated emissions Uncertainties Default allocation methodology used in the NEI assumes that the amount of fuel used by vessels within a port is proportional to the amount of cargo handled. Philadelphia is not a major commercial fishing port. Too much of the emissions may have been allocated to Philadelphia rather than among all the ports on the Delaware

11 Uncertainties Land-based cargo handling Contractor study Information was not available on the sizes of diesel engines used, age of equipment, or average engine loads. Operating hours were not directly available, but were estimated from ship traffic. Estimates were compatible with the NEI estimate for diesel construction and mining equipment in Philadelphia County.

17 Tioga Marine Diesel Particulate Emissions from Land-Based Cargo Handling Equipment Forklifts 9% Toploaders, 47 tons 20% Yard Tractors 71%

18 Next Steps Sub Committee of the Philadelphia Diesel Difference will focus on establishing a stakeholder group Determine which emission source categories and terminal to focus on at the Port of Philadelphia Evaluate possible control technologies for the Port of Philadelphia
