Dear Mr. Denard:

Motiva Enterprises LLC (Motiva) is providing the following comments on Draft NPDES Permit
NCO022209 received via email on October 4, 2016. As stated in your letter dated October 5,
2016, Motiva has made no significant changes to the facility since the last permit renewal and
has had no compliance issues; therefore, Motiva is requesting removal of the new limits and
analysis added to the draft permit. The additional limits create an added burden to the facility
that is not warranted by our historical compliance record.
The addition of the monthly average limit of 30.0 mg/L total suspended solids (TSS) is
effectively lowering the daily maximum from 45.0 mg/L to 30.0 mg/L since sampling is only
required once per month. Furthermore, the 30.0 mg/L TSS level is extremely low compared to
the United States Environmental Protection Agency (EPA) Multi -Sector General Permit (MSGP)
benchmark of 100 mg/L, which the EPA deems appropriate for compliance monitoring of
stormwater discharge from petroleum terminals. Motiva maintains that the current TSS limit is
protective of the receiving stream and the waters of the state of North Carolina and requests
that a more stringent limit is not added to the permit for TSS.
The addition of the turbidity analysis requirement is not warranted as the receiving stream is a
dry creek bed with intermittent flow and often zero flow and, therefore, does not support a fish
population. The existing 45.0 mg/L daily maximum TSS limit provides sufficient protection of
aquatic life in the receiving stream. Motiva requests that the turbidity analysis not be added to
the permit. Alternatively, if turbidity analysis must be added, it should be as a "monitoring only"
parameter as the EPA MSGP includes a benchmark level only for turbidity.
