Subject: Notice of Inspection - Not Compliant
Lots 54, 55, 56 & 57R Technology Drive
State Stormwater Management Permit No. SW8 020516
New Hanover County
Dear Mr. Jenson:
Donald van der Vaart
Secretary
On March 20, 2015, the Wilmington Regional Office of the Division of Energy, Mineral and Land
Resources (DEMLR) inspected Lots 54, 55, 56 & 57R Technology Drive, located in the North Chase
Industrial Park at 4540 Technology Drive in New Hanover County to determine the status of compliance
with the State Stormwater'Management Permit Number SW8 020516 issued on October 5, 2006.
DEMLR file review and site inspection revealed that the site is not in compliance with the terms and
conditions of this permit. Please find a copy of the completed form entitled "Compliance Inspection
Report" attached to this letter, which summarizes the findings of the recent inspection.
As indicated in the attached inspection report, the following deficiencies must be resolved:
1. The required Designer's Certification for the wet pond system constructed for Lot 57R has not
been submitted. The Division sent you a letter on April 11, 2014, which requested that you
submit the required certification. However, no response to that letter has been received to date.
The runoff from the remainder of the site is treated in the offsite wet detention pond permitted
under SW8 961004 under the purview of the Technology Court Owner's Association.
2. The permit must be modified to account for the retaining wall which has been added in the
pond.
3. The orifice may be clogged. The water level in the pond was close to going over the weir, but no
flow was observed from the orifice.
4. The relative elevation difference between the temporary pool elevation and the permanent pool
elevation did not appear to be 1.3 feet, as permitted.
5. The premises appeared vacant. If you have transferred ownership of this property to a new
owner, please download, complete and submit the below -referenced Name/Ownership Change
form from our website.
Please inform this Office in writing before May 8, 2015, of the specific actions that will be undertaken
and the time frame that will be required to correct the deficiencies. Failure to provide the requested
information, or to respond to this letter by the due date, may initiate enforcement action including the
assessment of civil penalties of up to $25,000 per day. If a written plan of action is not submitted to this
office by May 8, 2015, then DEMLR staff will re -inspect the site and issue a Notice of Violation if the
listed deficiencies have not been addressed.
Please be advised that you are required to comply with the terms, conditions and limitations of the
Stormwater Management Permit under Title 15A North Carolina Administrative Code 2H .1003 and
North Carolina General Statute 143-214.7, including operation and maintenance of the permitted
stormwater system. Violations of your Stormwater Management Permit may be subject to the
assessment of civil penalties of up to $25,000 per day per violation.
