Hello Chistine,
I've reviewed the proposed modification to the Orbit Energy facility, for the addition of a liquid offloading station at the
reception building, as noted in your email below and attachment.
The Section does not have any objections to this operational modification, and it can go forward. These changes should
be included in the permit renewal application.
If you have any questions, please let me know.

Hi Donna,
Per my voicemail this morning, I am following up on the request for approval of the minor construction project outlined
below and attached at Orbit Energy Charlotte. Can you please let us know the status? OEC has planned the construction
to begin next week, so we would appreciate a response as soon as possible..
Thanks,
Christine

Subject: Orbit Energy Charlotte Modification for Liquid Receiving
Hi Donna,
As we discussed a couple of weeks back, Orbit Energy Charlotte (OEC) is proposing to construct an additional liquid tank
truck unload station at their reception building where incoming feedstock is received. This minor modification is part of
an overall facility improvement plan for better efficiency in transfer of organic food waste. OEC would like to begin
construction this month, so we appreciate your expediting the review of this request.
Separately, I understand that NCDEQ has not completed the permit renewal for this facility. OEC would like to
incorporate this change as part of the permit renewal application. We included this request in the attached letter, but
let me know if you require any additional information.
Please feel free to contact me if you have any questions.
Thanks,
Christine

SUBJECT: REQUEST TO CONSTRUCT AND OPERATE MODIFICATION FOR LIQUID
RECEIVING
ORBIT ENERGY CHARLOTTE, LLC
SOLID WASTE PERMIT # 6033-AD-COMPOST-2015
Dear Ms. Wilson:
On behalf of Orbit Energy Charlotte, LLC (OEC), Kleinfelder, Inc. (Kleinfelder) is providing this
request to approve the construction and operation of an additional liquid offloading station at the
reception, storage, and loading system building. As previously discussed during our September
14, 2023 call, we understand that a written request with complete supporting information for the
project will allow the Solid Waste Section to expedite the review and approval of the change. This
minor modification will allow OEC to address improvements needed to address the current truck
back-ups that are occurring due to the lack of space for offloading.
Once OEC receives approval for construction of the liquid offloading station by the NCDEQ Solid
Waste Section, we will prepare an addendum to the application for renewal of the Solid Waste
Permit #6033-AD-COMPOST-2015 to include this project. We understand that the permit renewal
application submitted by OEC was received by your office on November 19, 2020 but the permit
has not yet been reissued due to staffing constraints and other priorities at NCDEQ Solid Waste
Section.
The following sections provide the project background and description of the proposed
modifications. Attachments to this letter provide drawings for the reception building processes.
Background
The proposed project involves the addition of a liquid tank truck offloading station at the reception
building to pump waste liquid feedstock to bio-squeezer slurry tank or the reception building slurry
pit. The liquids offloaded at this location will include food wastes that are currently accepted and
permitted by the facility (i.e., oils, fats, liquid foods). Currently, these liquids are being transferred
to the two bio-pulper tanks located at the southeast corner of the reception building. Only one
tank truck can be offloaded at time with the current set up (space constraints), causing truck back-
ups. The new station will alleviate this congestion.

This new delivery mechanism is part of an overall improvement plan by OEC to assist in the
efficient transfer and processing of organic food waste. GEC's longer -term goal is to accept more
liquid because they require less processing than packaged solid waste.
Project Description
A tank truck unloading station will be constructed at the northeast corner of the reception building.
The area will be constructed with a new secondary containment sump pit below the pipe
connection point to capture spills. The new secondary containment pit will be equipped with a
sump pump that will be operated as needed to convey liquids to the existing slurry pit in the
reception building.
Currently, liquid is added to the organic mix in the bio-squeezer via a slurry tank from other
sources (i.e., wastewater from treatment plant) to enable proper mixing and viscosity of food
solids prior to pumping to the two pre -load tanks.
Closing
We appreciate your expediting the review and approval of the proposed tank truck loading
connection station, as OEC is planning construction in October 2023. Please contact me at
704.309.7423 if you have any questions or require additional information.
Sincerely,
KLEINFELDER, INC.
