MJR SECTION
Enclosed please find the 1" Stormwater Sampling Report for the 2019 year- recorded on 1-24-
2019. Please note we are back within our threshold limits and in compliance. We will still continue
the following procedures to hold these limits below standard threshold.
1) We are having the parking lots swept and cleaned by.a 3`d party with heavy equipment.
2) We have installed cover/ roofing over any outside containment areas for chemical storage.
(Diesel, Kerosene, Paint etc...)
3) We had a 3`d party inspection which all areas of concern have been addressed and completed.
We will have monthly sampling done moving forward until we are confident the thresholds are
consistant and I will report as such to the DEHNR.
If you have questions or concerns, please contact me at 336.293.0316 or email at
[e-mail]

Re: Lyndon Steel Stormwater permit #NCG030474 CAN . 2018
To Whom It May Concern: C7"ipAS
Enclosed please find the 2nd recordable Stormwater Sampling Report for the 2018 year- recorded
on 06-22-2018.1 have initiated the following corrective actions because of the higher zinc levels
showing up in the sample reports.
1) We are having the parking lots swept and cleaned by a 3`d party with heavy equipment.
2) We are having a 3"d party inspect all areas of our properties and will address any concerns.
3) We are looking into pressure washing the parking lots and moving dumpsters to other locations.
We have initiated monthly sampling and I will report as such to the DEHNR Stormwater Mgt.
If you have questions or concerns, please contact me at 336.293.0316 or email at
[e-mail]
Sincerely,
Daniel Maiden

on 03-19-2018.1 have initiated the following corrective actions because of the higher zinc levels
showing up in the sample reports.
1) We are having the parking lots swept and cleaned by a 3`d party with heavy equipment.
2) We have installed cover/ roofing over any outside containment areas for chemical storage.
(Diesel, Kerosene, Paint etc... )
3) We are having a 3'd party inspect all areas of our properties and will address any concerns.
4) We are looking into pressure washing the parking lots and moving dumpsters to other locations.
We have initiated monthly sampling and I will report as such to the DEHNR Stormwater Mgt.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a
"representative storm event" or during a "measurable storm event." However, some permits do not have this requirement.
Please refer to these definitions, if applicable.
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 (3 days) 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.
A "measurable storm event" is a storm event that results in an actual discharge from the permitted site outfall. The previous
measurable storm event must h
able to document that a shorter

tendon Steel CoTRarr� - North Carolina
Storm water inspection report
The North Carolina NPDES Stormwatel`-Discharge Permit for Lyndon Steel requires serni-
annual inspections of the plant's storm water management systems. On October 4, 2017
inspected the plant, conducted an inventory of significant exposed materials and performed
visual monitoring of storm water. Several photographs relevant to the inspection are
included in this report.
Because Winston Steel and Stair is using a portion of this property for their operations, their
location was also inspected. Applicable photographs are included. As the main property
owner, Lyndon Steel is responsible for any storm water issues at this Winston Steel and Stair
location unless a separate NPDES permit is given for this part of the property. if both ,
companies have the same parent company / owner, one NPDES permit will cover this
property,
The findings and recommendations of this inspection are summarized as follows:
Lyndon Steel
• Both of the ASTs and their respective containment areas were in good condition and did
not exhibit any obvious signs of leakage (Photo 1).
• The outside drum storage areas appear to be in good condition. Containment appears
to be intact, with no obvious signs of leakage (Photos 2a-2c). The empty drum storage
area does not show signs of residual product leaks (Photo 2d).
• The dust collector unit was clean and did not show signs of damage or leaks (Photo 3).
• Drums in the painting area were observed to have closed lids when not in use (Photo 4a).
Some damage was noted in the spill pallet in this area (Photo 4b). OEI recommends that
the spill pallet be replaced in the near future.
• Several storm drains observed onsite did not show obvious signs of foam or oil sheen
(Photos 5a-5d).
• Drainage, outfall and nearby areas did not show obvious signs of pollution (Photos 6a-
6d).
• Personnel should be reminded to check that materials stored outside do not have any
oily or chemical residue (Photos 7a-7f).
• There was no rain on the day of inspection. The facility had normal outside production
storage. There were no obvious signs of pollution (Photos 8a-8g).

Lyndon Steel Company - North Carolina
Storm water inspection report
Winston Steel and Stair
• Outside chemical storage areas — the AST and new shed — have intact containment, with
no leaks or cracks (Photos 9a-9c). Personnel should be reminded that this storage
should be kept locked when not in use.
• Chemical bulk containers should be kept in this covered area -(Photo 10). The'containers
should be checked regularly for leaks that could migrate past the roofline.
• The overall facility has the same standard storage conditions. Other outside storage at
thefacility should be checked to ensure that these materials do not have any oily or
chemical residue (Photos 11a-11h).
This report should be filed with the plant's copy of the Stormwater Pollution Prevention
Plan. This documentation must be retained onsite for a period of five (5) years and made
available to the Director of the Division of Environmental Management or his/her
authorized representative upon request.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a
"representative storm event" or during a "measurable storm event" However, some permits do not have this requirement.
Please refer to these definitions, if applicable,
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 (3 days) 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.
A "measurable storm event" is a storm event that results in an actual discharge from the permitted site outfall. The previous
measurable storm event must h
able to document that a shorter
approval from the local DWQ Regional Office.

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
'Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. Yor those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event" However,
some permits do not have this requirement. PIease refer to these definitions, if applicable.
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 (3 days) 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.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a
"representative storm event" or during a "measurable storm event." However, some permits do not have this requirement.
Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.I inches of rainfall and that is preceded by at ]cast 72
hours (3 days) 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.
A "measurable storm event" is a storm event that results in an actual discharge from the permitted site outfall. The previous
measurable storm event must h
