Speciation Update: URG 3000N Carbon Sampler NESCAUM MAC Meeting Troy, New Hampshire April 24 – 25, 2007

STN Carbon Conversion Update Why? -Changes in the network to address inconsistencies in carbon sampling and analysis procedures used in urban STN/SLAMS and rural IMPROVE programs How? –EPA will manage coordination and implementation of conversion –EPA is using a contractor to procure, install and train operators on URG 3000-N sampler use –Contractor (with EPA) will contact and coordinate installation with Region/State agencies –Process will be repeated for rest of the network in batches of ~60 -Expect to complete first phase of conversion in mid ‘07

What Happens to the Filter? Once installations are complete, analysis will be switched to TOR analysis by DRI (Can DRI handle the workload?) All sites will move to new analysis at once Concurrent TOT and TOR collection and analysis will be done for about two months Sampling modules, cassettes, and analysis will continue to be supported and supplied by RTI Field blank collection and subtraction also to change

URG3000N Looks like IMPROVE? Identical to the IMPROVE sampler except: •Mass flow control •Sampler operation support provided by URG •Modules loaded/provided by RTI–Differs from typical STN •22.8 LPM flow rate •25-mm PallflexQuartz filter •Carbon Analysis–IMPROVE_A TOR method–Blank collection and subtraction

The URG 3000N installation requirements:   1. A minimum horizontal inlet spacing of 1-meter & a maximum of 4-meter between the SASS (or your current speciation sampler) and the new URG 3000N. 2. A maximum of 1-meter vertical inlet spacing between the SASS (or your current speciation sampler) and the new URG 3000N. 3. Two (2) outlets totaling 15 Amp. 115 VAC with in two (2) feet of the sampler. 4. Wooden or similar decking material to affix the sampler to the final sampler location. 5. Room to safely access the back of the instrument. The controller keyboard and memory card are on the back of the sampler. The keyboard can be removed and brought to the front on a coiled cord.

NY has 7 Speciation samplers Two are now collocated with URG3000N Samplers This one is in the South Bronx

URG3000N Sampler in Manhattan

Project Status: •About 30/57 sites done so far Rest of sites scheduled for April 30th completion •Planning for May 1ststart date •Working on URG3000N SOP for mid-April •Issues and Problems so far: Few sites not prepared for install (space and power issues) Handful of sampler startup issues Some agencies without FTS to check 22 LPM Lead time on parts/supplies from vendor
