REGAN Secretary MICHAEL SCOTT Director Sent Via E-Mail Laura Minor Resolve Environmental Services, PLLC 500 Devonport Drive Matthews, North Carolina 28104 resolve(a, Carolina. rr. com NORTH CAROLINA Environmental Quality August 5, 2020 Subject: Monitoring Well Abandonment Approval Former Scott Aviation Brownfields Property 309 & 310 W Crowell Street Monroe, Union County Brownfields Project Number 09042-05-090 Dear Mrs. Minor, The Department of Environmental Quality (DEQ) Brownfields Program received the Monitoring Well Abandonment Request dated July 15, 2020 for the above referenced Brownfields Property. DEQ Brownfields reviewed this document and discussed the request with Mike Rogers of the DEQ Inactive Hazardous Site Branch (IHSB). Based on the Initial Grading Plan Sheet No 2.20, select monitoring wells are likely within the 100-year flood plain and will not be disturbed during redevelopment. IHSB has a need for these monitoring wells MW-06, MW-07, MW-08 should be maintained during redevelopment activities. If they are damaged and/or abandoned, the developer will be responsible for replacement of these monitoring wells in accordance with Land Use Restriction (LUR) 14 of the Notice of Brownfields Property (NBP). With the exception of the aforementioned wells, the remaining site monitoring wells may be properly abandoned. Please provide monitoring well abandonment records in the annual Redevelopment Summary Report referenced LUR 10 of the NBP. Please be advised that this approval from DEQ Brownfields does not waive any applicable requirement to obtain any necessary permits, licenses or certifications which may be required from other state or local entities. If you have questions about this correspondence or require additional information, please feel free to contact me by phone at 704-661-0330 or by email at carolyn.minnich&ncdenr. gov Sincerely, C'+ Carolyn Minnich Brownfields Project Manager ec: Mike Rogers, DEQ IHSB e r�� D— Fm I North Carolina Department of Environmental Quality I Division of Waste Management 217 West ones Street 11646 Mail Service Center I Raleigh, North Carolina 27699-1646 919,707,8200 ab Resolve Environmental SeMcef, PIR July 15, 2020 Ms. Carolyn Minnich Brownfields Project Manager NCDEQ 610 East Center Avenue, Suite 301 Mooresville, NC 28115 Re: Monitoring Well Abandonment Request Fmr. Scott Aviation 309 & 310 W. Crowell Street Monroe, Union County, NC Project ID: 09042-05-090 Dear Ms. Minnich: On behalf of the City of Monroe, property owner of the Former Scott Aviation site, located at 309 and 310 West Crowell Street in Monroe, North Carolina, Resolve Environmental Services, PLLC (Resolve) requests permission to abandon the monitoring well network associated with the site. The site is currently being redeveloped by the City of Monroe. The request includes on -site monitoring wells MW-1 through MW-11, on -site bedrock monitoring wells P-1 through P-6 and off -site bedrock monitoring wells W-2A and W-3A. A table summarizing well construction data as well as site maps showing the well locations (highlighted) are attached, for reference. Please note that MW-5 needs to be abandoned as soon as possible due to ongoing site work (construction of sedimentation basin #2). A NC licensed well driller will properly abandon the wells per the NCDEQ guidelines. Please contact me at 704-289-5881 with any questions. Your timely review of this information is appreciated, as redevelopment is actively underway at the site.
