__ this size concerned him as a potential target He inquired whether the above-ground tank would bypass EPA or CEQA requirements. Ms. Vanessa Kawaihu, 871 Sycamore Rd., emphasized that this particular above-ground tank would replace three underground tanks. She noted that the staff report did not provide the proximity to the Sycamore Creek area or Applied Biosysten-is' retention pond. If there were to be a leak, she would prefer anabove-ground leak to an underground one so that the HazMat crews could address it immediately. Mr. Monceaux noted that two of the underground tanks were manifolded to each other and that it was difficult to do an isolated integrity test to ensure there was no lealcage_ He noted that they removed 46,000 gallons worth of tanks to be replaced. by a 12,000-gallon above-ground storage tank. In response to an inquiry by Chairperson Maas regarding testing of the soil after the tanks were removed, Mr_ Maloney replied that all of the soil and end water sample results came up with less than abottom-line number that any regulatory agency would require action on. There was no detectable evidence of chemicals or fuel., based on the requirements of the Water Board and the County Health Departrnents_ In response to an inquiry by Chairperson Maas regarding monitoring for an underground tank, Mr. Maloney replied that the monitoring system featured an alarm which was on 24/7_ He noted that it would monitor the fuel lines and the annular space between the first and secondary pipes. The sumps under the pumps had leakage monitors. While the technology was very good, it also depended on electrical switches and detectors that required constant maintenance. He noted that a monitor that was inoperable for even two days could be catastrophic. He noted that even in the newest technology, which they consistently install, the possibility of a problem always exists. In response to an inquiry by Chairperson Maas regarding the monitoring system for the above-ground tanks, Mr. Maloney noted that the best part of that system was its visibility and that there was nothing hidden on an above-ground tank, including the monitoring system. In response to an inquiry by Commissioner Blank whether the two 20,000-gallon underground tar~lcs had been removed, Mr_ Maloney said yes. In response to an inquiry by Commissioner Blank whether the drivers fueled their own trucks, Mr. Maloney conFx-nied that there was a fueler for on-site fueling. He noted that they often fueled the trucks en route to the site. He noted that the fueler was scheduled for five eight-hour work shins per week. Mr_ Monceaux noted that there were many above-ground tanks in use and that while the technology for underground tanks was very sophisticated, it was not as secure as that of the above-ground tanks. He added that those systems had more ii~herent problems. PLANNING COMMISSION MINUTES January 12, 2005 Page 8 of 21
