Section 1. Facility Activities and Process:
Consolidated Metco, Inc. is an aluminum foundry that produces cast aluminum products. Stock
aluminum is melted, molded or cast, and machined into various components. Typical processes or
equipment in operation at the facility included melting furnaces, aluminum casting, machining, heat
treating, and general maintenance. Several types of lubricating and cutting oils, hydraulic oils, coolants,
and corrosion inhibitors are used in various processes and equipment associated with production at the
facility.
Per a 2019 EPA inspection report, stormwater from western half of facility sheet flows, and just
downgradient of the outfall from the pond, a second corrugated pipe was observed discharging into the
tributary. Per information provided by the permittee on 4/24/2024, they have removed the scrap
equipment along with the hub storage from this area and do not believe this area needs to be permitted
as an additional stormwater discharge point based on the definition.
Outfall SW001:
Drainage area consists of product(aluminum casting and hub) storage areas, wood pallet storage areas,
metals storage areas, equipment storage areas, chemical storage shed, loading docks, diesel fuel tanks,
two (2) 18,000 gallon propane tanks, vapor/blending station, sand recycling roll-off bins, scrap metal
roll-off bins, trash compactors, and a detention basin. Discharge is from storage areas and the detention
basin.
Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
Page 1 of 7

For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."
Section 2. Monitoring Information and Compliance History:
• March 2019 to November 2023, benchmarks exceeded for:
o Aluminum Ix
• Per the May 2024 inspection report: The facility currently only samples from the basin outlet but
there is a flared end section that discharges to the same channel that the pond discharges. The
flared end section discharges stormwater from yard inlets in the storage yard where aluminum is
stored and must be sampled. The flared end section is comingled with stormwater from the road
so a background sample may be necessary to evaluate the road impacts on the flared end section
discharge. If the samples prove the road is not impacting the discharge, the facility could sample
towards the end of the channel after the two outlets comingle.

Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for March 2019 to November 2023. Quantitative sampling included pH, TSS, O&G, and
aluminum.
Page 2 of 7

Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the Consolidated Metco site.
Outfall SWO01

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan(SWPPP).
Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Parameter Benchmark Basis
Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)
Non-Polar Oil & Review of other state's daily maximum benchmark
Grease 15 mg/L concentration for this more targeted O&G;NC WQS that
EPA Method 1664 does not allow oil sheen in waters
SGT-HEM
BOD 30 mg/L BPJ; Based on Secondary Treatment Regulation (40 CFR
133.03
COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic
wastewaters
Aluminum Total 750 /L '/2 FAV
Copper Total 10 /L Acute Aquatic Criterion, '/2 FAV
Lead Total 75 /L Acute Aquatic Criterion, '/2 FAV
Zinc Total 126 /L Acute Aquatic Criterion, '/2 FAV
Page 4 of 7

Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier
Three. The Regional Engineer may direct the response actions on the part of the permittee as
provided in Tier Three, including reduced or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.

Section 4. Changes from previous permit to draft:
• Regulatory citations added
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• Feasibility study requirement removed per updated stormwater program requirements
• Annual online SWPPP certification requirement removed per updated stormwater program

• Monitoring added for total copper, total lead, and total zinc as the application stated metals are
stored outdoors
• Monitoring for total hardness added for outfalls where monitoring for hardness dependent metals
is required
• Benchmarks updated per guidance from DWR Standards group
Section 5. Changes from draft to final:
• None

Hey Brianna,
did an inspection there last week and they said you were working on their reissuance. The only funky thing I
caught was that they were only sampling from the pond outfall and there is another flared end section that
discharges to the same storm drain channel that picks up water from an aluminum storage area. He said that also
picks up road water and I told him to take a background sample of just the road water coming into their drain to
see if it negatively impacts the results from the flared end section. If that sample is good,then they could have one
outfall below where the two outfalls comingle. I don't know what EPA said in their inspection 6 years ago, so if you
weren't aware, I just wanted to let you know. If you need anything from me,just let me know.
Thanks,
Lily

Comment: The facility currently only samples from the basin outlet but there is a flared end section that
discharges to the same channel that the pond discharges. The flared end section discharges
stormwater from yard inlets in the storage yard where aluminum is stored and must be
sampled. The flared end section is comingled with stormwater from the road so a background
sample may be necessary to evaluate the road impacts on the flared end section discharge. If
the samples prove the road is not impacting the discharge, the facility could sample towards
the end of the channel after the two outlets comingle.

Brianna
also apologize for the incorrect information given to Lily during the inspection.As shown in the picture attached,
this is where we have been pulling our samples for some time and is down stream from the pipe from our retention
pond to ensure proper sampling has been completed.
We are in the process of getting our equipment and procedures together to ensure conformance to the new
requirements.

Thanks for the call yesterday Brianna and the discussion.
As requested we spoke with Lily Kay yesterday afternoon and cleared up the confusion I caused. I am sorry about
that.
There is only one outfall and we take the sample at the bottom of it.
Many thanks,

Good morning,
It has come to my attention that the facility has two outfalls, not just one as stated in the permit application. Please
provide the outfall coordinates (in DMS), receiving stream, industrial activity(ies)that occur in the drainage area, and
any chemicals stored in the drainage area.

Brianna,
Thanks for the scrub and review.
We have attached these items requested and provided responses in blue.
• Provide analytical and visual monitoring data from the last permit issuance date to current.
o Attached entitled, "Storm Water Monitor Discharge Outfall Report—2019—2023—Permit Renewal"and
"Visual Storm water Discharge Outfoll Monitoring Report—2019—2023."
• Provide a summary of BMPs.
o Attached entitled, "Potential Best Management Practices Implemented—Storm Water Permit Renewal".
• Provide a short narrative of any significant changes.
o Attached entitled, "Stormwater Permit Renewal NCS000324—Short Description Change Narrative for
Industrial Activity—2-15-2024."
• Confirm the name of the receiving stream (the application lists Stewarts Creek but this stream is further away
from the facility than other streams).
o We have reviewed and determined that Stewarts Creek is the closest to the outfall as the recognized
stream.
• Confirm if any part of the property sheet flows (information from a 2019 EPA inspection indicated this occurs).
o We have reviewed and removed the scrap equipment along with the hub storage from this area. We do
not believe this area needs to be permitted as an additional stormwater discharge point based on the
definition.
• On the site map, identify what industrial activity is occurring in each of the numbered areas (the key only says
they're locations of exposed industrial activity).
o Attached entitled, "Site Map Industrial Activity Appendix 4-23-24."
Let us know if you have any questions.

Good morning Adam,
Based on a quick review, EPA Forms 1 and 2F look to have all boxes/fields filled in. However,the following information is
missing(per the supplemental information form):
• Analytical monitoring data (from the last permit issuance date to current)
• Visual monitoring data (from the last permit issuance date to current)
• Summary of BMPs
• A short narrative of any significant changes
Please note I did not do an in-depth review of your application, so I may have additional questions or require additional
information once I begin my review.The above items are just the missing requirements I see at quick glance. Please note
a hard copy must of the application (with wet-ink signature) must be mailed to us. Please let me know if you have any
additional questions.

Thanks Brianna for the email.
All the documentation is ready.We are working to get the samples from the lab.
I spoke to the lab this week and they have to pull one more sample of BOD.
We are opening to pull that sample todaywith a rain event scheduled to occur.
If the rain event does not occur today we have several events we are watching for next week.
My goal is to send all the documentation and the samples to you by 4/12.
Please let me know if this is sufficient or we need to adjust our timeline.

Adam,
After a quick glance,the documents attached on your email seem to cover the request for"The SPPP Certification
Form, Supplemental Information Form, and all the required information/attachments of these items needs
to be provided."
However, I did not see the following items attached to your email:
• Signature on Section 5.1 of EPA Form 2F is needed(a name was typed in the signature box—a wet ink
signature is required for this item).
• Tables A, C, and D of EPA Form 2F must be filled out. Historical monitoring data taken during the
previous permit cycle may be used for tables A and C, and Table D must contain information on the
storm event used for data reported in Tables A and C.
Regarding your question for Table A: Yes,you need to complete this table. Please fill in the data using historical
monitoring data for parameters that were required to be monitored in your current permit as well as for any pollutants
you expect to be present in your stormwater discharge. You do not need to take separate samples or provide data for
pollutants not in your current permit and that you do not expect to be present in your discharge. Please let me know if
you have any further questions.
Thank you,

Brianna,
I went through the documentation to make the updates and changes required I think.
Before I formally sent this to you in the mail and resent through email with a complete package updated,would mind
taking a look to ensure I did not miss anything that is needed please?
One question I did have is—
Item 7.2 and Table A.All applicants must complete Table A. If the discharge is an existing discharge and your discharge is
composed exclusively of stormwater(i.e., no process or non-process wastewater) then you only need to provide
monitoring data for oil and grease, total phosphorus, total Kjeldahl nitrogen, and total nitrogen. Indicate "NA"for"not
applicable"in the columns for all other parameters.Answer"Yes"to Item 7.2 once you have completed this task.
This is something I need to complete correct?
Thanks again for your help and attention.
Thanks,

asked them to sample both pipes and the background road water to help them determine where they should
sample, i.e. if the flared end section exceeds a parameter,they need to evaluate the road sample to see if it is the
contributor. If not,they'd be good to sample below both discharges. It's up to you.

Thanks, Lily. So you feel the facility has 2 outfalls but there is a place they can sample downstream of both to have just 1
permitted outfall? Did they state when they intended to do the sampling?Just wondering if I should hold the permit for
those results, with a modified outfall location, or if I should move forward and get information from them for two
permitted outfalls.

Hey Brianna,
did an inspection there last week and they said you were working on their reissuance. The only funky thing I
caught was that they were only sampling from the pond outfall and there is another flared end section that
discharges to the same storm drain channel that picks up water from an aluminum storage area. He said that also
picks up road water and I told him to take a background sample of just the road water coming into their drain to
see if it negatively impacts the results from the flared end section. If that sample is good,then they could have one
outfall below where the two outfalls comingle. I don't know what EPA said in their inspection 6 years ago, so if you
weren't aware, I just wanted to let you know. If you need anything from me,just let me know.
Thanks,
Lily

Brianna,
Thanks for the scrub and review.
We have attached these items requested and provided responses in blue.
• Provide analytical and visual monitoring data from the last permit issuance date to current.
o Attached entitled, "Storm Water Monitor Discharge Outfall Report—2019—2023—Permit Renewal"and
"Visual Storm water Discharge Outfall Monitoring Report—2019—2023."
• Provide a summary of BMPs.
o Attached entitled, "Potential Best Management Practices Implemented—Storm Water Permit Renewal".
• Provide a short narrative of any significant changes.
o Attached entitled, "Stormwater Permit Renewal NCS000324—Short Description Change Narrative for
Industrial Activity—2-15-2024."
• Confirm the name of the receiving stream (the application lists Stewarts Creek but this stream is further away
from the facility than other streams).
o We have reviewed and determined that Stewarts Creek is the closest to the outfall as the recognized
stream.
• Confirm if any part of the property sheet flows (information from a 2019 EPA inspection indicated this occurs).
o We have reviewed and removed the scrap equipment along with the hub storage from this area. We do
not believe this area needs to be permitted as an additional stormwater discharge point based on the
definition.
• On the site map, identify what industrial activity is occurring in each of the numbered areas (the key only says
they're locations of exposed industrial activity).
o Attached entitled, "Site Map Industrial Activity Appendix 4-23-24."
Let us know if you have any questions.

Stormwater Permit Renewal NCS000324—Short Description Change Narrative for Industrial Activity
At the facility a trash compactor was added that is fully enclosed and has a catch pan for the hydraulic
basin to set in to prevent oils from getting onto the ground in the event of a leak.
Recycling has been moved from the outside and is no longer a practice at the facility.

Site Map Industrial Activity Appendix
Number Activity Description
Two propane tanks and the associated vaporizer/blending station are located in
the foundry yard on the southwest side of the facility within paved areas and chain
link fence. Stormwater may contact the tanks and equipment but should not be
1 ropane Tanks&Vaporizer/Blending Static contaminated. If propane is released during a storm event,a minor amount of
contamination may result. Stormwater contacting the tank will flow northeast
toward drop inlets and to the wet detention basin prior to discharge through Outfall
001.
Wood pallets are stored uncovered on paved surfaces in several areas outside of
plant buildings. Wood pallets in good condition will be picked up for recycling.
Damaged wood pallets may be disposed in an open top roll-off bin. The potential
2 Wood Pallet Storage exists for wood pallets surfaces to be contaminated with oily residuals or other
chemical residual contamination. Stormwater contacting the wood pallets will flow
over the paved surfaces to nearby drop inlets or across gravel and grass surfaces
to the wet detention basin prior to discharge through Outfall 001.
Six fuel oil tanks are located on the northwest side of the property near the
detention basin. Stormwater will contact three of the tanks and three are located
3 Fuel Oil Tanks within the nearby generator enclosures. Fuel transfer areas will be exposed to
stormwater. Stormwater contacting the tanks will flow into nearby storm drains,
which discharge to the wet detention basin prior flowing through Outfall 001.
Exposed stacked aluminum castings and hubs are stored on paved surfaces in
several areas exposed to stormwater. Some are in process products and some
completed products,the later provided with plastic wrap and largely protected from
4 Aluminum Casting&Hub Storage stormwater. Stormwater run-off from storage area(s) along the east wall of the
plant flows directly through Outfall 001 and is not captured by the wet detention
basin. Stormwater run-off from storage areas inside the fence and along the west
side of the property flows into the basin.
Steel section and pipe rack(s), material handling parts and equipment, bailed
cardboard, staged boxes, and other inert materials are stored outside on paved
and gravel surfaces on the west, east and north sides of the property outside of
5 Outdoor Materials&Equipment Storage the building and within the security fence. Stormwater contacting miscellaneous
materials and equipment storage on the north and west areas will run off into the
wet detention basin prior to Outfall 001,while run-off from the east areas will flow
directly to Outfall 001.
Open top roll-off bins used to collect scrap metal,off quality aluminum parts,
waste packaging materials,production waste,etc.are located in several outdoor
areas.Some of the bins(e.g.production waste and aluminum shavings)are
located under a shelter. All roll-off bins are located on paved surfaces. The
6 Roll-Off Bins for Recycle and Disposal potential exists for stormwater that has contacted oily surfaces or picked up
particulate in the bin to leach to paved surfaces. Poor housekeeping around the
bin will also contribute pollutants to stormwater run-off. Stormwater run-off from
the bin locations flows to the wet detention basin prior to discharge through Outfall
001.
Loading docks are located at several locations. Docks are provided with seal
pads which protect loading and unloading operations from stormwater. Significant
7 Loading Docks vehicle traffic and unloading of chemical products provides the opportunity for
leaks and spill to paved areas exposed to stormwater. Stormwater contacting the
loading docks will flow to the wet detention basin prior to discharge through Outfall
001.
Lubricants, coolants, corrosion inhibitors, hydraulic fluids and chemicals
associated with metal working are stored in the shed located in the south corner of
the facility. Although most of the shed floor is sloped toward a containment pit,
some of the floor area slopes away from the building. A concrete curb provides
8 Chemical Storage Shed spill containment for that section of floor. Potential exists for leaks and spills to
flow out of the sheltered area and become exposed to stormwater. The metal
shavings roll-off bin described in Item#6 above provides the opportunity for oil to
leak onto paved surfaces during handling and be exposed to stormwater. The
potential also exists for spills during product deliveries. Stormwater run-off from
the shed area flows to drop inlets that discharge to the wet detention basin.

Good morning Adam,
Based on a quick review, EPA Forms 1 and 2F look to have all boxes/fields filled in. However,the following information is
missing(per the supplemental information form):
• Analytical monitoring data (from the last permit issuance date to current)
• Visual monitoring data (from the last permit issuance date to current)
• Summary of BMPs
• A short narrative of any significant changes
Please note I did not do an in-depth review of your application, so I may have additional questions or require additional
information once I begin my review.The above items are just the missing requirements I see at quick glance. Please note
a hard copy must of the application (with wet-ink signature) must be mailed to us. Please let me know if you have any
additional questions.

Thanks Brianna for the email.
All the documentation is ready.We are working to get the samples from the lab.
I spoke to the lab this week and they have to pull one more sample of BOD.
We are opening to pull that sample todaywith a rain event scheduled to occur.
If the rain event does not occur today we have several events we are watching for next week.
My goal is to send all the documentation and the samples to you by 4/12.
Please let me know if this is sufficient or we need to adjust our timeline.

Adam,
After a quick glance,the documents attached on your email seem to cover the request for"The SPPP Certification
Form, Supplemental information Form, and all the required information/attachments of these items needs
to be provided."
However, I did not see the following items attached to your email:
• Signature on Section 5.1 of EPA Form 2F is needed(a name was typed in the signature box—a wet ink
signature is required for this item).

• Tables A, C, and D of EPA Form 2F must be filled out. Historical monitoring data taken during the
previous permit cycle may be used for tables A and C, and Table D must contain information on the
storm event used for data reported in Tables A and C.
Regarding your question for Table A: Yes,you need to complete this table. Please fill in the data using historical
monitoring data for parameters that were required to be monitored in your current permit as well as for any pollutants
you expect to be present in your stormwater discharge. You do not need to take separate samples or provide data for
pollutants not in your current permit and that you do not expect to be present in your discharge. Please let me know if
you have any further questions.

I went through the documentation to make the updates and changes required I think.
Before I formally sent this to you in the mail and resent through email with a complete package updated,would mind
taking a look to ensure I did not miss anything that is needed please?
One question I did have is—
Item 7.2 and Table A.All applicants must complete Table A. If the discharge is an existing discharge and your discharge is
composed exclusively of stormwater(i.e., no process or non-process wastewater) then you only need to provide
monitoring data for oil and grease, total phosphorus, total Kjeldahl nitrogen, and total nitrogen. Indicate "NA"for"not
applicable"in the columns for all other parameters.Answer"Yes"to Item 7.2 once you have completed this task.

This is something I need to complete correct?
Thanks again for your help and attention.
Thanks,

Thanks Brianna for the email.
All the documentation is ready.We are working to get the samples from the lab.
I spoke to the lab this week and they have to pull one more sample of BOD.
We are opening to pull that sample todaywith a rain event scheduled to occur.
If the rain event does not occur today we have several events we are watching for next week.
My goal is to send all the documentation and the samples to you by 4/12.
Please let me know if this is sufficient or we need to adjust our timeline.

Adam,
After a quick glance,the documents attached on your email seem to cover the request for"The SPPP Certification
Form, Supplemental Information Form, and all the required information/attachments of these items needs
to be provided."
However, I did not see the following items attached to your email:
• Signature on Section 5.1 of EPA Form 2F is needed(a name was typed in the signature box—a wet ink
signature is required for this item).
• Tables A, C, and D of EPA Form 2F must be filled out. Historical monitoring data taken during the
previous permit cycle may be used for tables A and C, and Table D must contain information on the
storm event used for data reported in Tables A and C.
4

Regarding your question for Table A: Yes,you need to complete this table. Please fill in the data using historical
monitoring data for parameters that were required to be monitored in your current permit as well as for any pollutants
you expect to be present in your stormwater discharge. You do not need to take separate samples or provide data for
pollutants not in your current permit and that you do not expect to be present in your discharge. Please let me know if
you have any further questions.

Adam,
After a quick glance,the documents attached on your email seem to cover the request for"The SPPP Certification
Form, Supplemental Information Form, and all the required information/attachments of these items needs
to be provided."
However, I did not see the following items attached to your email:
1

• Signature on Section 5.1 of EPA Form 2F is needed(a name was typed in the signature box a wet ink
signature is required for this item).
• Tables A, C, and D of EPA Form 2F must be filled out. Historical monitoring data taken during the
previous permit cycle may be used for tables A and C, and Table D must contain information on the
storm event used for data reported in Tables A and C.
Regarding your question for Table A:Yes,you need to complete this table. Please fill in the data using historical
monitoring data for parameters that were required to be monitored in your current permit as well as for any pollutants
you expect to be present in your stormwater discharge. You do not need to take separate samples or provide data for
pollutants not in your current permit and that you do not expect to be present in your discharge. Please let me know if
you have any further questions.
Thank you,

Brianna,
I went through the documentation to make the updates and changes required I think.
Before I formally sent this to you in the mail and resent through email with a complete package updated, would mind
taking a look to ensure I did not miss anything that is needed please?
One question I did have is—
Item 7.2 and Table A.All applicants must complete Table A. If the discharge is an existing discharge and your discharge is
composed exclusively of stormwater(i.e., no process or non-process wastewater) then you only need to provide
2

monitoring data for oil and grease, total phosphorus, total Kjeldahl nitrogen, and total nitrogen. Indicate "NA"for "not
applicable"in the columns for all other parameters.Answer"Yes"to Item 7.2 once you have completed this task.
This is something I need to complete correct?
Thanks again for your help and attention.
Thanks,
Adam Hamilton
