Here is the latest report on the petroleum remediation cleanup at Sellers Auto/Artist Studio on Philadelphia Avenue.
In addition, here is other news on the site.
After working with Orange County for some weeks to come up with a plan to alleviate the noise generated by the oxidizer system, we have reached a compromise. Noise from the project site was measured and determined to exceed the Orange County noise ordinance. It was consistently aggravating and unacceptable to residents living on Philadelphia Street and New York Avenue for several weeks.
Orange County has added sound attenuating panels that have significantly reduced the noise in the area described. Although noise readings coming from the system still exceed acceptable limits (by 2%), nearby residents have agreed to allow the project to continue as-is with the new sound attenuating panels in place. If all goes well, the oxidizer will run for the next 90 days, 24-7, as planned to achieve project goals. After 90 days the oxidizer portion of the project will be dismantled and operations will resume with the remaining, less noisy, equipment.
Orange County has also approved budget to have the project contractor add “Jersey poles” (cylindrical concrete poles) around the exposed 1,000 gallon propane tank located near the street on Philadelphia Avenue. Orange County agreed with nearby residents that, due to the exposed/unprotected position of the propane tank near peak truck and traffic flows east and west on South Lake Formosa Drive and north and south on Philadelphia Avenue, the tank presents a potential safety and health hazard to nearby residents should a vehicular accident cause damage to the tank.
Mr. Taylor has agreed to speak at the next LFNA general meeting on April 15, 2008 to go over project milestones, cleanup status, and the above-referenced topics. He needs about 20 minutes with 10 minutes for Q&A.
–Forwarded Message Attachment–Subject: Monthly update for Sellers Auto / Artist Studio petroleum cleanup site 489201547 / 489201548 (Seventeenth update- March 3, 2008)Date: Mon, 3 Mar 2008 16:21:32 -0500From: Damon.Taylor@ocfl.netTo: firstname.lastname@example.orgCC: Carlos.Gonzalez2@ocfl.net; Renee.Parker@ocfl.net; email@example.com; firstname.lastname@example.org; JRWebster@r-kidproperties.comMs. Mills,I would like to take this opportunity to give you our Seventeenth monthly update on the project. It is now one year since startup occurred so we are one fourth through the projected cleanup time of four years. The site is back up again as it was re-started at the beginning of February and has been retrofitted with noise attenuating panels to address the noise concerns you brought up in the last couple of weeks. Mr. Horton, provided a schedule of the work for the quarter and it looks like the next round of groundwater sampling is scheduled for April 9th. I will ask that he get the samples turned around as soon as possible so that we may have data available for our meeting on April 15th. Please note that I will be out of town at the beginning of next month and will not be able to provide an update until the HOA meeting. However, after our meeting I will provide a mid April e-mail update to include forthcoming data as well as follow up on our meeting for your website for those that may miss the HOA meeting. Report Status:Currently there are no new reports are in house for review, except for the ones that Terramax (the former contractor) is sending / has sent to respond our past letters. Then next reports due to the county are as follows:1) Operational report to cover the system in period of the beginning of February through the end of April – due on July 1, 2008. I believe Argus will be able to submit that report significantly before that date though. 2) Operational report to cover the system in period of the beginning of May through the end of July – due on October 2, 2008. I believe Argus will be able to submit that report significantly earlier as well. 3) Operational report to cover the system in period of the beginning of August through the end of October – due on December 31, 2008. I believe Argus will be able to submit that report significantly earlier as well. A cost proposal to continue the system operation is going to be negotiated in early October for the next fiscal year.General System Status:We collected noise readings at 5am on Philadelphia Avenue outside the equipment compound at the property boundary when the system was off and when the system is on. The noise reading showed that the system on resulted in a 22% increase in sound compared with the background reading. If this is acceptable to you for now, I believe the noise level will go down even further after the oxidizer is no longer needed. Unfortunately the oxidizer cannot be stopped and started each day. However cycling the system is an option after the oxidizer is taken off line. I am happy to provide another noise measurement after the oxidizer is taken off line. The Division believes that a higher water recovery rate may be possible on the 24 multiphase extraction wells and that once the water table is lowered, that the soil vapor extraction rate will become more efficient. The limiting factor that affects our recovery rate is that there is a backpressure on the liquid phase carbon vessels that polish the treated water before it gets pumped to the gallery. The backpressure may be caused by a natural mineral and (possible) biomass buildup that restricts the flow of the treated water. Argus is requesting the use of a sequestering agent, but has not obtained approval yet. In the meantime, a manual cleaning of the equipment is the only option to ensure that the treated water may be pumped out as fast as it is coming in. The current flow of treated water is approximately 30-35 gallons per minute. Milestone Update:There is no new information regarding the milestones as no new groundwater data will exist until mid April. I look forward to providing a brief presentation to the Lake Formosa Homeowners Association on April 15th. Please feel free to call me anytime if you need additional information or if you would like me to find something in our files.Thank you,Damon Taylor, CFEA, LEP Orange County Environmental Protection Division Petroleum Cleanup Team 800 N.
