SUPPLEMENTAL INFORMATION
SITE MAPS AND OUTFALLS
The GE Aerospace facility, located in Castle Hayne, North Carolina in the County of
New Hanover, encompasses approximately 100 acres. It is co-located with the Global
Nuclear Fuel-Americas, LLC facility that is covered under the NPDES Stormwater
Permit No. NCS00022 for its stormwater discharges.The impervious portions of the GE
Aerospace facility encompass approximately 45 acres. The remaining portions of the
facility are primarily forest and ponds. The attached Site Location Map and Site
Drainage and Significant Materials Map presents the location of the industrial
activities,stormwater drainage structures, drainage areas, outfalls, building locations,
and roads for the developed portions of the facility.
The entire 1,660-acre property inclusive of Global Nuclear Fuel-Americas, LLC and GE
Aerospace is bordered on the east by NC Highway 133, on the southwest by the
Northeast Cape Fear River, and on the north and most of the south by undeveloped
forestlands. Stormwater discharges to two receiving water bodies: the Northeast
Cape Fear River and Prince George Creek. Neither is shown on the site map due to
their distance from the developed portion of the facility. The Northeast Cape Fear
River receives the majority of the stormwater runoff from the adjacent Global Nuclear
Fuel-Americas, LLC property. Prince George Creek, located approximately 5 miles
north of the facility, receives stormwater runoff from the GE Aerospace portion of the
facility.
There are a total of seventeen stormwater outfalls/drainage basins(1, 2,3,4, 5, 6, 7,
8/8i,9. 10, 11, 12, 13/13i, 14, 15/151, 16,and 18)for the Global Nuclear Fuel-Americas,
LLC and GE Aerospace facilities. It is noted that there is no outfall 17. Outfalls 2, 3, 4, 5,
6, 7, 8/8i, and 15/15i will be transferred to a new permit for GE Aerospace. Outfalls 1,
9, 10, 11, 12, 13/13i, 14, 16 and 18 will remain on NPDES stormwater permit
NCS000022.
Representative outfall status (ROS) was initially granted by NC DWQ (Division) in a
letter dated August 13, 1991 such that Outfalls 9, 13, and 14 are representative of all
stormwater outfalls at the facility. ROS was modified to Outfalls 9, 13i, and 15i in the
NPDES renewal permit in Division's letter dated November �, 2014. A ROS Renewal
Certification Form will be submitted to the Division under separate cover, as the ROS
is now a separate review process and not handled during the permit application
process.
Table 1 identifies the latitude and longitude, total drainage area, percentage of
impervious area,and receiving water body for each outfall.
Table 2 presents the significant materials and potential pollutants at GE Aerospace.
These potential stormwater sources are numbered by outfall and are shown on the Site
Drainage and Significant Material Map using the source numbers pertaining to GE
Aerospace from the first column of Table 2.

SECTION NO. 2
SUPPLEMENTAL INFORMATION
ANALYTICAL MONITORING
A summary of twelve analytical benchmark monitoring events conducted during the
term of the previous permit NCS000022 is included on the subsequent pages. The
previous permit required analytical monitoring at three representative outfolls (#9,
#13i, and #150 on a semi-annual basis for the entire duration of the permit term
during a representative storm event. Onlu Outfall 15i will be transferred to the new
permit for GE Aerospace. Outfall 9 is representative of stormwater discharges from
Outfall 6, 7, and 8, but will be retained under permit NCS000022. The new NPDES
permit NCS000022 was issued on January 31, 2024 and took effect on March 1, 2024.
Therefore, results provided are for previous permit parameters from 2018 through
2023.
Grab samples were collected within the first 30 minutes of a measurable storm event
(a storm event that results in actual discharge) and preceded by at least 72 hours
prior to a previous measurable storm event. The following parameters and storm
characteristics were monitored.
1. Lead,total recoverable (mg/L)
2. Non-Polar Oil and Grease(mg/L)
3. Total Suspended Solids(mg/L)
4. pH (standard units)
5. Total Rainfall
Analytical benchmark monitoring results are summarized on Table 3 for Outfall 15i.
Per the previous permit, monitoring for vehicle maintenance activities was not
required because the site did not use more than 55 gallons of new motor oil per
month when averaged over the calendar year.

SECTION NO. 3
SUPPLEMENTAL INFORMATION
VISUAL MONITORING
Qualitative visual monitoring occurs at all stormwater outfalls each year on a
semiannual basis, once in the first half of the year between January 1 and June 30,
and again in the second half between July 1 and December 30.There is a minimum
of 60 days between any two monitoring events. Visual observation is conducted of
the following characteristics: color, odor, clarity, floating solids, suspended solids,
foam,oil sheen,erosion and any other indicator of stormwater pollution.
To facilitate the visual monitoring inspections, placards have been posted at all
stormwater outfalls. This ensures consistent location evaluation during visual
monitoring,outfall inspections,and non-stormwater discharge assessments.
Semi-annual outfall visual monitoring events are tracked in the Compliance Calendar.
This program alerts the GE owner of the task that the visual monitoring must occur,
and the task remains 'open" until completed and closed in the system. The completed
visual monitoring results are maintained in that year's SWPPP binder.
The subsequent pages summarize the semi-annual visual monitoring results by
outfall from 2018 through 2023 for outfalls 2, 3, 4, 5, 6, 7, 8/8i, and 15/15i. The
information has been summarized in the table based on completed Stormwater
Discharge Outfall ISDOI reports. Values greater or equal to 3 are investigated and
documented in the SWPPP for that year.

SECTION NO. 4
SUPPLEMENTAL INFORMATION
BEST MANAGEMENT PRACTICES
GE Aerospace is committed to preventing pollution at the source, and as such, has
implemented numerous best management practices (BMPs) and at-source
stormwater pollution prevention controls to reduce the quantity of pollutants in the
stormwater runoff. The structural controls (e.g., containment, dike, curb, and/or roof)
and management practices employed at the individual significant materials at GE
Aerospace are listed in Table 2 in the Supplemental Information Section No. 1. The
site-wide BMPs that are utilized by GE Aerospace are described in this section and
include:
=> Good Housekeeping,
=> Inspections/Preventative Maintenance Program,
=> Outside Material Storage/Tanks/Secondary Containment,
=> Material Handling,
=:> Spill Prevention and Response,
=> Sewer and Outfall Identification, and
=> Employee Training.
Good Housekeeping
GE Aerospace maintains a clean and orderly facility through implementation of a
variety of programs, practices, and procedures, including:
■ Regular pickup and disposal of garbage and debris
■ Routine inspection for leaks
■ Proper material container storage practices
■ Identification and labeling of all chemical substances
■ Disposal of old equipment and used chemicals
These housekeeping practices help to reduce waste and pollutant generation,
as well as the potential for spills and leaks.
Inspections/Preventative Maintenance Program
The preventive maintenance program at GE Aerospace ensures that the stormwater
control facilities are clean and operating effectively. The program consists of visual
inspection, cleaning, and repair activities. Inspections are conducted at the
stormwater controls and the significant materials identified on the Site Map and
Table 2 in the Supplemental Information Section No. 1. At a minimum, these
inspections are conducted semiannually (quarterly once the new permit takes
effect). Upon completion of the inspection, any cleaning and repair activities, if
needed, are documented. Completion of the inspections, cleaning, and repairs are
tracked electronically.
GE Aerospace—NPDES Stormwater Permit Application Section 4
Page 4-1

Specific inspection areas include:
■ Material handling and storage areas
■ Secondary containment areas
■ Stormwater outfalls
■ Catch basins and trench drains
■ Roofs and covers
■ Potential spills and areas of possible contamination
Outside Material Storage/Tanks/Secondary Containment
GE Aerospace's practices and activities related to outside material storage areas and
aboveground tanks are in place to prevent or minimize contact of significant
materials with stormwater. Many material storage areas are covered and/or have
containment curbing or grading. Aboveground tanks are in compliance with federal
and state laws for containment, integrity testing, overflow protection, and protective
guards. Stormwater retained by the curbing or dikes is visually inspected for
contaminants prior to release.
BMPs currently in use include:
■ Provide secondary containment for liquid storage
■ Provide containment curbing,dikes,and/or grading
■ Cover materials to eliminate exposure to stormwater
■ Store materials on pallets or racks
■ Visually inspect stormwater retained by curbing/dikes/containment prior to
release
■ Move storage areas inside if possible
Material Handling
Material loading and unloading is typically conducted in areas designed to reduce
potential contact with stormwater. Loading areas for bulk chemical transfers are
either:(1)contained to allow visual inspection of stormwater prior to release, or(2) are
graded to direct stormwater to the process drain system for treatment prior to
discharge. The stormwater is contained during transfer operations by secondary
containment, curbing, grading, trays, and/or drain covers. Further, manual valves in
the closed position have been installed in select storm drains.
Direct pipeline transfers are in place for several materials and waste streams. This
method of material transfer greatly reduces the potential of stormwater
contamination.
There are detailed written guidelines on loading and unloading procedures in the Spill
Prevention Control and Countermeasures Plan.
Spill Prevention and Response
GE Aerospace has written procedures on spill prevention and response. These
procedures describe the protocol of responding to a spill and the individuals at the
site who should be contacted. The procedures are included in the facility Spill

Prevention Control and Countermeasures Plan. Site staff are trained on spill
prevention and response.
Employee Training
The Employee Education and Training Program is designed to familiarize employees
with the intent and components of the Stormwater Pollution Prevention Plan.
Training is provided for employees involved in operations with the potential to affect
stormwater.
Topics included in the training session include:
■ General stormwater awareness
■ How to use the Stormwater Pollution Prevention Plan
■ Chemical spill response procedures
■ Preventative maintenance
■ Inspection procedures
■ Materials management practices
■ Good housekeeping measures
■ Data entry in the stormwater database
Sewer and Outfall Identification
There are three separate drainage collection systems at the facility: process
wastewater, sanitary wastewater, and stormwater. Sewer manhole covers and
catch basins have been color-coded to distinguish between these systems.
Also, as described previously, placards have been posted at all stormwater outfalls.
This ensures consistent location evaluation during visual monitoring, outfall
inspections, and non-stormwater discharge assessments. A photograph of each
outfall and placard is included in an Appendix of the Stormwater Pollution Prevention
Pla n.
