Permit Renewal
Dear Ms. Young,
In response to above referenced draft permit, issued on April 30, 2024 for the PCS
Morehead City Port Terminal Facility, please see the comments referenced in the
attached copy of the draft permit(w/highlights):
1. Outfall Labeling:
■ Page 15
The permit states:"Table 1. Summary of Quarterly Baseline Sampling Requirements
for Stormwater Discharges for Outfalls SW001 and SW002."
■ Page 16
The outfalls are labeled"Outfall SW 100 and Outfall SW200."
The outfalls should be labeled Outfall SW100 and Outfall SW200,as detailed in the previous
permits.
2. Benchmarks for pH Monitoring
Page 15 -The Benchmark for pH is currently listed as 6.8 s.u.—8.5 s.u. In the footnotes
there is a statement"instead of 6 SU."
Should the footnote also read 6.8 SU.?
3. After discussion and agreement with the North Carolina Port Authority(NCPA),NCPA
intends to submit a permit modification to add the referenced outfall to their facility permit
within 90 days of this letter being submitted.
Outfall SW200 should be removed from this permit and incorporated in the NCPA
stormwater permit.

1. Measurement frequency:Quarterly during a measurable storm event.If the facility is monitoring monthly
due to Tier Two or Tier Three response actions,the facility shall continue a monthly monitoring and
reporting schedule in Tier Two or Tier Three status until relief is granted.
2. If pH values outside this range are recorded in sampled stormwater discharges,but ambient precipitation
pH levels are lower,then the lower threshold of this benchmark range is the pH of the precipitation
(within instrument accuracy)instead of 6 s.u:.Readings from an on-site or local rain gauge(or local
precipitation data)must be documented to demonstrate background concentrations were below the
benchmark pH range.
3. For each sampled measurable storm event,the total precipitation must be recorded.An on-site rain gauge
is required.Where isolated sites are unmanned for extended periods of time,a local rain gauge reading
may be substitute for an on-site reading.

4. The permittee shall document tidal influences at that time of the sample to record whether samples were
taken at high or low tide conditions(or a more average condition in between).
• Outfall-SW100, Drainage area consists of phosphate storage buildings and conveyor belts.
• Qutfall SW200r Drainage area consists of a phosphate storage building,a dumpster,and piles of
scrap wood, stone base,and metal debris.
Should the permittee identify or create any new stormwater outfalls,remove any stormwater outfalls
identified in this permit,or alter any drainage areas that change the potential pollutants in runoff
discharged through corresponding outfalls,the permittee will submit a request to NC DEMLR to modify
this permit.For any newly discovered pipes or outfalls,the permittee must evaluate the structure and
provide a report of the status and planned actions to NC DEQ within 14 days.The permittee must either
(1)request modification of this permit and modify the SWPPP accordingly,or(2)eliminate potential
discharges by removal,plugging,or combination of both.
D-3. Methodology for Collecting Samples
[40 CFR 122.416); 15A NCAC 02H.0143(a)(22)J
(a) Outfall monitoring efforts shall begin with the first measurable storm event that occurs during the
facility's normal operating hours and begins at least 72 hours after the previous measurable storm
event.
(b) Grab samples shall be collected within the first 30 minutes of discharge. If physical separation
between outfalls prevents collecting samples from all outfalls within the first 30 minutes of
discharge, then the permittee may continue collecting samples until all outfalls that are
discharging have been sampled.
(c) Outfalls that are not discharging during or after the first measurable storm event shall be sampled
during the next measurable storm event,until a sample has been collected from every outfall.
(d) If,during an entire monitoring period,there is no discharge from an outfall during any measurable
storm event that occurs during the facility's normal operating hours and begins at least 72 hours
after the previous measurable storm event,then the permittee shall report"No Discharge"in the
DMR and shall record"No Discharge"in the SWPPP.In this case,the DMR shall be submitted
within 30 days after the end of the monitoring period.Lack of a discharge from an outfall for the
monitoring period shall not constitute failure to monitor as long as this condition is met.
(e) Sampling is not required to be performed outside of the facility's normal operating hours or
during adverse weather conditions.
(f) Samples collected shall be characteristic of the volume and nature of the permitted discharge.
(g) If the sampled storm event coincides with a known non-stormwater discharge that is deemed
permitted under 15A NCAC 02H .0106,then this shall be noted on the stormwater discharge
monitoring report.
D4. Locations for Collecting Samples
[40 CFR 122.416); 15A NCAC 02H.0143(a)(22)J
Samples shall be collected at all stormwater discharge outfalls(SDOs)that discharge stormwater
associated with industrial activity.If the Division has issued a representative outfall status(ROS)
approval letter,then the permittee shall collect samples from all SDOs in accordance with the ROS
approval letter.
