SUMMARY OF CHANGES IN INDUSTRIAL ACTIVITY AT
3114 / 3124 CULLMAN AVE.
Detrex Corporation (DTRX) owns two buildings located at 3114 and 3124. Cullman Avenue.
Prior to June of 2002, DTRX operated out of both buildings. As seen by the. enclosed figures,
the 3124 address is a warehouse for storing USDOT containerized products and the 3114 address
is utilized for the operation of the RCRA Part B Permit (TSDF).
In June of 2002, DTRX sold the product portion of its business and related transportation
equipment to the former president of the division. The transition from a single entity to two
entities was seamless and did not alter overall operations as they existed prior to the transfer.
Former DTRX personnel now work for Parts Cleaning Technologies (PCT). Under a
management agreement PCT provides the manpower DTRX needs to operate its permit.
Detrex has and continues to operate under its RCRA Part B Permit (TSDF) at 3I14 Cullman
Ave. Under our permit, this site accepts, stores, and reclaims halogenated solvents via a
distillation unit. In addition, the Facility accepts and stores other hazardous, non-RCRA,
non -hazardous, and other solid waste streams, in conjunction with the TSDF operation. All
wastes are contained within the building at 3114 Cullman Ave. or on trailers located between the
buildings. NO wastes are disposed of on site. All activities associated with the TSDF operations
occur within the building except for the transfer of waste and product into the building under
applicable DOT regulations.
The new entity PCT, operates their local office out of 3124 Cullman Ave. for warehouse
distribution DOT containerized products, cleaning of parts supplied by customers, and as a base
for their fleet associated with the transportation of parts, products, and waste materials. They
continue to sell process chemistry to companies who clean their own parts using halogenated
solvents. The main products sold by PCT are Trichloroethylene, Tetrachloroethylene, and N-
Propyl_Bromie. The PCT also sells a very limited volume of 1,1,1- Trichloroethane, as this
material is no longer in production and the available supply is dwindling.
Bulk products sold by PCT continue to be stored at 3114 Cullman Ave. due to the location of
existing storage tanks. Most bulk storage tanks are located inside of the building. The amount
of material stored in the outside tank farm has been reduced by decommissioning and in most
cases removing the storage tanks. As of the submission of this request for renewal of the
NPDES permit, there is only one active storage tank remaining in the diked tank farm. The
outside tank is utilized by PCT for the storage of Tetrachloroethylene.

Dear Mr. Craig:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains:
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameter, Chemical Oxygen Demand (COD), has been added to this permit.
2. pH has been added to the analytical monitoring requirements. .
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B,The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period,; the permittee must submit a monitoring report indicating "No Flow"
within 30 d- ays of the end of the sixmonth sampling period. Additionally, samples must be taken.a
minimum of 60 days apart, as specified in Table 2. -
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the pennittee to increase monitoring, increase management actions, increase record
keeping; and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall follow the
Tier guidelines which require a.repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all paranieters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
.5. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of .
representative outfall status.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnoted of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall -
parameter is in this permit, however.)

8. Vehicle maintenance monitoring has been revised to semi -amorally in order to coincide with analytical
and qualitative monitoring. This requireiirent appears in all Individual Stormwater permits, however it
only applies to facilities that do vehicle maintenance. If the facility begins vehicle maintenance during the
permitted timeframe then the requirements shall apply.
Other permit changes:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected, to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part 1I
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
A. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part lI Section A. . .
5. Information regarding the No Exposure Exclusion has been added to this draft permit. I( industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
6. Per the requirements of the Catawba Riparian Buffer Rule, all stormwater drainage from portions of
this site that have been constructed after June 30, 2001 must be discharged through a correctly
designed level spreader or another device that meets diffuse flow requirements per 15A NCAC 2B
.0243. Diffuse flow requirements are described in Chapter 8 of the North Carolina Stormwater BMP
Manual, available at: http://h2o.enr.state.nc.us/su/bmp forms htrm
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

Central Office Review Summary:
I. Owner's Other Permits:
Air/AFS 3711900114
NE12NC0I 14
RCRA NCD049773245
2. General Observations: Detrex operates under a RCRA Part B Permit (TSDF) at 3114 Cullman Ave.
3. Impairment. Little Sugar Creek (I I-137-8a, 11-137-8b, 11-137-8c) is on the 303(d). 11-137-8a is the closest
to the facility and is on the 303d list for Standard violation: Fecal Colifonn and Impaired biological integrity.
11-137-8b for Standard violation: Fecal Colifonn and Impaired biological integrity. l 1-137-8c for Standard
violations: Fecal Coliform and Tubidity and Impaired biological integrity. Sources for each of the reaches
include Urban Runoff/Storm Sewers and Municipal.
The basinwide plan described the 03-08-34 watershed. The four streams (Irwin Creek [AU# 1 1-137-1], Little
Sugar Creek [AU# I 1-137-8], McAlpine Creek [AU# 11-137-9a and I I-137-9c], Sugar Creek [AU# 11-137a
and 1 1-137b]) and their smaller tributaries collectively drain the metropolitan center of Charlotte in
Mecklenburg County. The watershed receives large amounts of point and nonpoint pollution from the urban
areas, severely impacting stream health in each of the streams. Similar habitat conditions are found at all
sample sites within this watershed, sand/silt substrate, Section B: Chapter 5 - Catawba River Subbasin 03-08-34
151 severe bank erosion, and disturbed or nonexistent riparian vegetation. Elevated levels of both fecal
coliform bacteria and turbidity indicate impairment by urban runoff and wastewater discharges in all four
streams. Water quality in general has remained low but stable over the last planning cycle. In 2002, declines
were noted on Sugar Creek (B-2) and Little Sugar Creek (B-3), but this decline was most likely due to the
severe drought. Sugar Creek has a TMDL for fecal coliform.
4. Threatened and Endan ee red: Based on the Natural Heritage Virtual Workroom there are no federally
endangered species near the facility and receiving stream.
5. Location: C stream
6. Industrial Changes Since Previous Permit: Detrex Corporation (DTRX) owns two buildings located at 3114 and
3124 Cullman Avenue. Prior to June of 2002, DTRX operated out of both buildings. As seen by the enclosed
figures with the application, the 3124 address is a warehouse for storing USDOT containerized products and
the 31 14 address is utilized for the operation of the RCRA Part B Permit (TSDF).
In June of 2002, DTRX sold the product portion of its business and related transportation equipment to the
former president of the division. The transition from a single entity to two entities was seamless and did not
alter overall operations as they existed prior to the transfer. Former DTRX personnel now work for Parts
Cleaning Techologies (PCT). Under a management agreement PCT provides the manpower DTRX need to
operate its permit.
Dctrex has and continues to operate under its RCRA Part B Permit (TSDF) at 3114 Cullman Ave. Under our
permit, this site accepts, stores, and reclaims halogenated solvents via a distillation unit. In addition, the
Facility accepts and stores other hazardous, non-RCRA, non -hazardous, and other solid waste streams, in
conjunction with the TSDF operation. All wastes are contained within the building at 3114 Cullman Ave. or on
trailers located between the buildings. No wastes are disposed of on site. All activities associated with the
TSDF operations occur within the building except for the transfer of waste and product into the building under
applicable DOT regulations.
The new entity PCT, operates their local office out of 3124 Cullman Ave. for warehouse distribution DOT
containerized products, cleaning of parts supplied by customers, and as a base for their fleet associated with the
transportation of parts, products, and waste materials. They continue to sell process chemistry to companies
who clean their own parts using halogenated solvents. The main products sold by PCT are Trichloroethylene,
Tetrachloroethylene, and N-Propyl Bromic. The PCT also sells a very limited volume of 1, 1, 1 -Trichloroethane,
as this material is no longer in production and the available supply is dwindling.

NCS000213
Bulk products sold by PCT continue to be stored at 31 14 Cullman Ave due to the location of existing storage
tanks. Most bulk storage tanks are located inside of the building. The amount of material stored in the outside
tank farm has been reduced by decommissioning and in most cases removing the storage tanks. As of the
submission of this request for renewal of the NPDES permit, there is only on active storage tank remaining in
the diked tank farm. The outside tank is utilized by PCT for the storage of Tetrachloroethylene.
7. Analytical Monitoring Notes: No analytical monitoring was required in the previous permit.
The industry (SIC code 2899) is covered in the EPA Multi -Sector General Permit in Sector C but there are not
parameters recommended for monitoring. COD has been added to the monitoring as a potential pollutant.
8. Qualitative Monitoring Notes: Visual observations were done from 3/23/09 to 1 1/1 1 /04. All of the entries say
"clear; no sheen, phase separation, discoloration, or strange odors."
Page 5 of 8

NCS0002 l3
Revised Permit Recommendations: Analytical Monitoring:
I . Adding COD as a parameter.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the penmittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier I guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition
of the steps listed for Tier I and also immediately institute monthly monitoring for all parameters at every
outfall where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during
representative storm events as defined in Part 11 Section B. Qualitative monitoring is required regardless of
representative outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote I of Tables 1,
4, and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
I . Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II
Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do
not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials
and activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may
qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional
information is provided in Part I Section A.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours. "&' .�%
