NEXT MEETING ____________________

Monday July 26 – John Van Winkle – City Traffic Engineer, Chattanooga

“Photo Enforcement for Stop Lights and Speed Limits”

Mr. Van Winkle will discuss photo enforcement of traffic regulations in Chattanooga, including: 1) its history--how it started and how it developed, 2) current strategy--how we decide where to deploy the cameras, and 3) how we use the revenue generated by the program to further enhance traffic safety in the community.

John is a registered Professional Engineer in the State of Tennessee and holds a BS in Civil Engineering and an MS in Traffic Engineering from the University of Tennessee. He has over 33 years of experience in the traffic engineering, including service as City Traffic Engineer since 1991.

DUES INCREASE RECOMMENDED

Club Officers met July 13 and reviewed club finances. Club expenditures have exceeded income for the last two years. (Last year, we increased the 2010 dues for Full and Associate members from $50 to $60 per year. We considered raising Retiree dues, but did not.) The officers now recommend that we increase the 2011 dues for Retired Members from $30 to $40. This recommendation will be advertised for two weeks, and then voted on by members present on the third week.\

PREVIOUS MEETING____________________

Monday July 19 – Scott McKenzie – March Adams & Associates

“Seasonal Adjustment of Gasoline with On-Line Butane Blending”

Scott McKenzie explained why gasoline properties are required to vary seasonally and regionally - to limit smog-forming characteristics, while maximizing fuel performance. He also explained that bulk adjustments are made at the refinery and at the beginning of the pipeline, but fine-tuning of these properties is often done at the final distribution terminal, just as gasoline is loaded into tank trucks.

Butane is often added to gasoline as a vapor-pressure modifier. Since butane is generally cheaper than gasoline there is a profit motive to maximize the addition rate while not incurring penalties for creating an “out of spec” product.

Mr. McKenzie discussed the installation parameters for an on-line butane blending system and reviewed the components, testing requirements and the challenges that come with working in this highly regulated industry.

Mr. McKenzie is a senior engineer with March Adams and Associates, with 30 years experience. He holds Bachelor’s degree in Mechanical Engineering from Georgia Tech and is a registered Professional Engineer in 18 states
