O. BOX 4185 MIDLAND, TEXAS 79704 2404 COMMERCE MIDLAND, TEXAS 79703 www.hy-bon.com Date: October 11, 2006 Mr. Gerard G. Alberts Williams Company Principal Environmental Specialist 1515 Arapahoe St, Tower 3, Suite 1000 Denver, CO 80202 Mr. Alberts, Per our conversation yesterday, electric drive vapor recovery units have very minimal down time. As a packager of vapor recovery units for over 50 years, as well as a company that maintains over 100 similar size units in a rental fleet that are often on "run time" contracts, we estimate average run time on Hy -Bon electric drive vapor recovery units to average 95%. This down time percentage assumes that the unit Is properly installed and properly maintained. This percentage coincides with the "over 95%° quoted in an article we had published in the American 00 and Gas Reporter (attached — see last sentence In the article). It also matches the figures used by the Natural Gas STAR program. The STAR presentation on vapor recovery states "vapor recovery can capture up to 95% of the gas from the tanks". We can make no assertions as to the run time viability of other manufacturer's equipment — especially in vapor recovery service. Vapor recovery is a very specialized application that requires a great deal of experience in working with wet gas at very low pressures. Many companies represent that they sell "vapor recovery units" but actually have little or no experience in thls niche application — resulting in projects with extremely poor run times capturing gas. However, we are confident in the run time estimates we provide for Hy -Bon equipment, and it's my sincere hope we have an opportunity to work with Williams Company on this project. Best Regards.
