Ms. Higgins,
On 11/8 at approximately 1030, a piece of equipment had a fitting failure which resulted in the release of approximately
1 quart of hydraulic oil while working in Rocky Swamp (Halifax County). ACP reported the release to the NCDEQ spill
hotline (incident number 201803324) at approximately 1115. Attached is the follow-up written notification from the
incident as well. Since Monday will be a holiday, the letter will be mailed out to your office on Tuesday. Should you

RE: Follow-up written submission for Permit DWR #20140957 (Incident No.
201803324) spill of hydraulic oil within wetland WHLH023E, Atlantic Coast Pipeline
Spread 8
Dear Ms. Higgins:
This letter is to follow-up on the hydraulic oil spill to waters of the state previously reported
on November 8, 2018, and as required by Individual Water Quality Certification Permit No.
20140957. Dominion Energy takes environmental compliance very seriously and
immediately notified the Division of Water Resources, Raleigh Regional Office upon
discovery of this hydraulic oil spill, and took immediate action to remedy this issue. The
discharge information and corrective actions are as follows:
11/8/2018 (Incident No. 201803324) —Spread 8 —During the placement of a timber mat
travel lane through delineated wetland WHLH02 in, apiece of equipment developed a leak
on a hydraulic fitting, resulting in an approximate 1 quart release of hydraulic oil within the
delineated wetland. Most of the fluid was released onto the timber mat travel lane; however
some hydraulic fluid was sprayed within the inundated wetland surface water creating a
sheen on top of the water. Upon discovery, the equipment was removed from the wetland, a
spill kit was deployed for containment (boom and absorbent diapers), and was left in place
until all fluid was absorbed and no sheen was present. To prevent any further release, the
equipment was removed from service until proper repairs were made.
If you have any questions
or
need additional information, please feel free to contact
