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

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.
Sincerely,
Laura Minor, Project Manager

Silt Fence Notes
a. Use a synthetic filter fabric of at least 95% by weight
of polyolefins or polyester, which is certified by the
manufacturer or supplier as conforming to the
requirements in ASTM D 6461.
b. Synthetic filter fabric should contain ultraviolet ray
inhibitors and stabilizers to provide a minimum of 6
months of expected usable construction life at a
temperature range of 0 to 120 degrees Fahrenheit.
C. Ensure that posts for sediment fences are 1.33
Ib/linear ft steel with a minimum length of 5 feet.
Make sure that steel posts have projections to
facilitate fastening the fabric.
d. For reinforcement of standard strength filter fabric,
use wire fence with a minimum 14 gauge and a
maximum mesh spacing of 6 inches.
e. Silt fencing to have wire backing.
