Jerry,
Here is an update of sources by drainage area. I reviewed and noted sources/buildings no longer used at the
facility.
Please let me know if you need any additional information.
We request that
• SWO A represent Drainage area IV
• SWO B represent drainage areas V&VI
• SWO C represent drainage area VII
Thankyou,
Jenny
Areal
Area I is approximately 9.19 acres in size with one 17,000 square-foot structure(Gundrill Room-empty building).
The remainder of the area consists of asphalt paved parking areas, gravel paved storage areas,storage areas
(including coke, limestone,and slag), and natural landscaped areas. Outside areas between the Gundrill Room
and on-ramp to I-77N were previously used as storage space for coke, limestone,slag. Minimal amounts may
remain for disposal. Outside areas between the Gundrill Room and Clarkson Street are primarily unused parking
areas. The Gun Drill building structure is currently unused.
In September 2018, North Carolina Stormwater Division removed our requirement to sample from this area as it
was not deemed to accurately represent stormwater flow from industrial areas(it includes run-off from
stormwater drains not on Charlotte Pipe property and run-off from I-277).
Area II
Area II is approximately 2.90 acres in size with one 51,000 square-foot warehouse structure.The remainder of the
area consists of asphalt paved parking areas and natural landscaped areas. The building structure is used
primarily as a warehouse with approximately 20 percent of the floor space used for offices. All items are currently
in the process of being removed from the Warehouse. Storm drainage from Area II drains via storm drainage
structures and storm drainage pipes to a drop inlet structure located on the southwestern corner of the area
(Appendix A, Figure 2). The Warehouse is currently being leased to a movie company.
In May 2009, North Carolina Stormwater Division removed our requirement to sample from this drop inlet
structure as there is no industrial activity in this area.

Area III
Area III is approximately 3.33 acres in size with four structures totaling approximately 16,918 square-feet.Three
buildings(storage)are located on the northern portion of the area and one building(Quality Control) is located on
the southern portion of the area.The remainder of the area consists of asphalt paved and gravel paved
areas. Charlotte Pipe has ended its lease of the Quality Control building, and it is now being leased to a new
tenant. Storm drainage from Area III drains via sheet flow to South Clarkson Street where it is runs into a street
storm drainage system (Appendix A, Figure 2). North Carolina Stormwater Division is not requiring sampling of the
sheet flow as there is no industrial activity in this area.
Area IV
Area IV is approximately 7.44 acres in size with five structures totaling approximately 17,780 square-feet. Three
buildings are located on the western portion of the area on the main Charlotte Pipe property(Product Bundling
Shed,Small Office Building,and Water Treatment). The Product Bundling Shed and Small Office Building are
unused. The Water Treatment Plant is still in operation.Two buildings are located on the west side of
Clarkson Street(Shipping Department, a portion of the Pattern Storage Building). Both buildings are
currently unused.The remainder of the area consists of asphalt paved areas which are no longer used, gravel
paved areas, and natural landscaped areas. Storm drainage from Area IV drains via storm drainage structures and
storm drainage pipes to a pipe discharging into Irwin Creek.
NC Stormwater Division is aware that there is continuous flow through many of the storm drainage structures due
to groundwater entering the stormwater system upstream of the Charlotte Pipe facility.
In May 2020, North Carolina Stormwater Division identified sheet flow at Outfall A to be representative of storm
water drainage from Areas V. In addition, in a letter dated May 27, 2020,the Division granted regulatory relief from
the Tier responses based on the condition that the TSS Abatement/Best Management Plan be continued,and that
quarterly reports documenting maintenance be submitted to NC.
Area V
Area V is approximately 2.28 acres in size with four structures totaling approximately 23,000 square-feet.Two of
the buildings are the main office buildings for Charlotte Pipe, one building is the Machine Shop and one building is
the Welding Shop. The Main Office areas are currently being leased to a movie company. The Machine Shop
and Welding Shop are no longer used. The remainder of the area was previously used for scrap iron storage
areas and asphalt parking areas. Storm drainage from Area V drains via storm drainage structures and storm
drainage pipes to a pipe discharging into Irwin Creek.
NC Stormwater Division is aware that there is continuous flow through many of the storm drainage structures due
to groundwater entering the stormwater system upstream of the Charlotte Pipe facility.
In May 2020, North Carolina Stormwater Division identified sheet flow at Outfall B to be representative of storm
water drainage from Area V. In addition, in a letter dated May 27,2020,the Division granted regulatory relief from
the Tier responses based on the condition that the TSS Abatement/Best Management Plan be continued,and that
quarterly reports documenting maintenance be submitted to NC.
Area VI
Area VI is approximately 1.78 acres in size with two structures totaling approximately 12,109 square-feet.The
Pattern Storage Building, is located west of and across Clarkson Street from the main foundry buildings, is
currently unused. One building,the Main Entrance Guard Shack, is located in the main foundry area. The Guard
Shack is manned 24 hrs/day. The remainder of the area consists of asphalt paved drives and parking, a 15,000-
gallon hot dip asphalt tank(emptied)and natural landscaped areas. Storm drainage from Area VI drains via storm
drainage structures and storm drainage pipes to a pipe discharging into Irwin Creek.

NC Stormwater Division is aware that there is continuous flow through many of the storm drainage structures due
to groundwater entering the stormwater system upstream of the Charlotte Pipe facility.
In May 2020, North Carolina Stormwater Division identified sheet flow at Outf all B to be representative of storm
water drainage from Area VI. In addition, in a letter dated May 27,2020,the Division granted regulatory relief from
the Tier responses based on the condition that the TSS Abatement/Best Management Plan be continued, and that
quarterly reports documenting maintenance be submitted to NC.
Area VII
Area VII is approximately 12.50 acres in size with the main foundry buildings, support buildings, bulk material
spent storage area,fuel aboveground storage tanks (ASTs),fueling station,and oil storage building(Oil
House). The majority of the building structures are currently unused but still store process equipment until it
can be removed. The only operation currently active at the site is the Pipe E-Coat Operation(which includes
a reaming/shotblast,a-coat,and printing/paint operations). This equipment is all located in one location of
the foundry buildings. The majority of stormwater from this area is run off from the roofs of the foundry buildings.
The remainder of the area consists of asphalt paved parking and storage areas,gravel paved parking and storage
areas,the fuel AST area (used minimally),the bulk material spent storage area(currently used to stage
materials to be removed from the site),and natural landscaped areas.The area was previously used primarily
for parking space(no longer used for parking),and storage space for spent bulk materials,fuel storage tanks
(minimal usage), bin storage for finished products(removed from site),and miscellaneous equipment used at
the facility. Storm drainage from Area VII drains via storm drainage structures and storm drainage pipes
discharging ultimately into Irwin Creek.
NC Stormwater Division is aware that there is continuous flow through many of the storm drainage structures due
to groundwater entering the stormwater system upstream of the Charlotte Pipe facility.A small quantity of
stormwater from Area VII (north of the Rolocast Finishing building and east of Clarkson Street)drains via sheet
flow to South Clarkson Street where it is collected in the street storm drainage system under 1-277 (John Belk
Freeway) overpass.
In May 2020, North Carolina Stormwater Division identified sheet flow at Outfall C to be representative of storm
water drainage from Area VII. In addition, in a letter dated May 27,2020,the Division granted regulatory relief from
the Tier responses based on the condition that the TSS Abatement/Best Management Plan be continued,and that
quarterly reports documenting maintenance be submitted to NC.

Ms. Pappalardo:
I have reviewed the ROS requestfor NCS000040 and need additional information before approvingthe
request. The map that was provided does not clearly show the drainage areas or activities within those drainage
areas. I understand these outfalls were previously approved as representative. However,the information
submitted with the ROS request must support the request. Please provide a site map that clearly shows the
drainage areas for each outfall, and either shows or lists the industrial activities within each outfall.
3

Also, note that the ROS application requests that outfall SWO04 be represented by both Outfall SWO08 (aka Outfall
A), and Outfall SW009(aka Outfall B). One outfall cannot be represented by two other outfalls. Please clarify this
request.
