Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On -site Representatives:
The following personnel were in attendance during the inspection: Kellie Hedrick/Environmental
Process Solutions - ORC, Jimmy Jordan/CDIA — Environmental Manager and Josh Eller/CDIA —
Environmental Compliance Specialist.
STORMWATER:
The Stormwater Pollution Prevention Plan (SPPP) records were organized and well maintained.
Facility stormwater inspections were performed (usually with tenants) in 2018. Employee/Tenant
training events were performed in December 2018 and the SPPP was last updated in February 2019.
The facility must ensure that the effectiveness of any on -site structural BMPs are re-evaluated (and
documented) as part of the annual SPPP update.
Semi-annual qualitative monitoring was performed at twenty-six (26) stormwater outfalls and
documented on the Division approved forms. Analytical monitoring (quarterly) at the representative
outfall locations (002, 003, F, H, K, 004) was performed in March, April, May, September and November
2018 and April 2019. The following benchmark exceedances were reported during the 4/23/18, 9/26/18
and 12/14/18 sampling events:
4/23/18 — Outfall 002 (COD, turbidity, TSS) and Outfall 003 (BOD);
9/26/18 — Outfall 004 (turbidity);
12/14/18 — Outfall 002 (BOD), Outfall 004 (turbidity) and Outfall H (turbidity).
Note: Outfall 004 is an instream background station upstream of the CDIA facility located in Coffey
Creek.
The last sampling during a de-icing event was performed at all representative outfalls (002, 003, F, H,
K, 004) on 4/3/19. The subject permit only requires monitoring during de-icing events at Outfalls 002
and 004. Benchmark exceedances for BOD and COD were reported at Outfall 002. The additional
monitoring at the remaining outfalls also revealed benchmark exceedances at Outfall 003 for BOD and
COD. The summary of aircraft de-icing fluid usage for the winter season (October 2018 — April 2018)
was included with the May 2019 edmr. Urea is no longer being purchased and sodium formate is now
the primary solid deicer.
NON-STORMWATER DISCHARGE:
The wastewater from the airplanes is removed and transported to a centralized location (Triturator)
prior to being conveyed into the sanitary sewer system. Residual paper debris was observed on the
ground leading to the stormwater drainage system. Note: No discharges were observed during this
inspection. Due to the history of poor housekeeping measures and unpermitted wastewater
discharges into the stormwater drainage systemat at this location, CDIA staff should perform (and
document) periodic inspections throughout the week to ensure all wastewater/paper products are
being properly disposed.
PETROLEUM RELEASE:
CDIA staff have continued to address small petroleum releases originating from the bank and into
Coffey Creek adjacent to the American Airlines Maintenance Hangar. The petroleum sheens were
originally observed in Coffey Creek in early December 2018 and CDIA staff initiated remedial activities
including the containment, collection and disposal of the petroleum discharges. The origin of the
petroleum discharges has not been determined and the assessment and delineation activities are
currently being performed according to the Division of Waste Management/UST Section's
requirements. Petroleum sheens were observed at this location during this inspection. Absorbent
pads were immediately placed in the stream to contain/collect the petroleum discharges. CDIA staff

must continue to ensure that all absorbent pads, booms, etc. are properly maintained at all times until
the source and all affected areas are properly remediated.
