<br />PERMIT BRIEFING MEMO <br />Honeywell International – Groundwater Remediation <br />1. Facility Description <br />Honeywell International, Inc. installed the Naphtha Recovery Well System in 1978 and VOC Recovery Well <br />system in 1988. The Naphtha Recovery Well system was used to remove free product from the top of the <br />water table until no further free product was detected in 2003. The well systems currently act as water-table <br />depression wells to control groundwater from migrating off-site. In 2021 a catalytic-oxidation soil vapor <br />extraction (SVE) treatment system was installed to remove volatile organic compounds from the soil above <br />the water table. VOCs are destroyed in the catalytic oxidation process and any remaining VOCS are sent <br />through an exhaust stack. Water cycles through a scrubber in the exhaust stack to reduce HCL emissions. <br /> <br />2. Discharge description: <br />Currently, the Naphtha Recovery Well system consists of three (3) recovery wells: E3A, RWB-16, and RWB- <br />23 with a total average discharge rate of 0.086 mgd. <br />Maximum allowable discharge of 0.173 mgd. <br /> <br />The VOC Recovery Well system consists of four (4) recovery wells: EW-1R, EW-2, EW-3 and EW-5R <br />with a total average discharge flow of 0.069 mgd. <br />Maximum allowable discharge of 0.154 mgd. <br />Soil Vapor Extraction system <br />Spent Scrubber water is stored onsite inside two frac tanks, totaling 40,000 gallon capacity, until batch <br />discharge occurs. Discharge will be on an as needed basis, with a 7,000 -gallon capacity tanker truck. <br />Estimated Discharge Rate: Average 500 gallons per minute, Maximum 1,000 gallons per minute. <br />3. Sample Site Description <br />The Naphtha System and VOC System maps indicating the well locations can be found in the Honeywell <br />Groundwater Remediation permit application dated January 14, 2020. <br />Naphtha Recovery Well System: <br />Monitoring is conducted at each of the three (3) operating Naphtha Recovery Wells. Samples are collected <br />from spigots at each well. Each discharge point has a totalizer meter to record flows. <br />VOC Recovery Well System: <br />Monitoring is conducted at each of the four (4) operating VOC Recovery Wells. Samples are collected from <br />spigots at each well. Each discharge point has a totalizer meter to record flows. <br />Soil Vapor Extraction System
