Enclosed are the results for the 31 consecutive samples to satisfy the Tier II
requirements listed in our Permit. We have enclosed an original and one copy of the 311
consecutive sample taken to satisfy the Tier II requirements in Masonite's Charlotte
North Carolina Entry Door Plant Stormwater Plan. Since this is the 3rd consecutive
sample taken with results of Zinc below the expressed limit we will revert back to semi-
annual testing. Our next sample results will be conducted between January ist and June
30th 2019.
If you have any questions concerning the results, please contact me at 704-921-3507 or

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
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. 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 rontain 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.

Please verify whether Qualitative Monitoring must be performed during a "representative storm event "
or "measureable storm event" (requirements vary, depending on the permit).
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. Please refer to these definitions, if applicable.
i
JA "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 treasuring greater than 0.1 inches
jhas occurred. A single storm event may contain up to 10 consecutive hours of no precipitation.
IA "measurable storm event" is a storm event that results in an actual discharge from the permitted site I
joutfall. 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

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 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.
See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 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).

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.- For 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

;Qualitative monitoring requirements vary. Mosi pennits require qualitative monitoring to be performed
during, a "representative storm event - or during a "measureable storm event." However• some permits do
not have this requiremenm. Please refer to these definitions, if applicable.
A "representative storm event" is a storm evem that measures greater than 0.1 inches of raintall and
that is preceded by at least 72 hours 13 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.
JA "measurable storm event" is a stone 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
inter% -al does not apply if the pennilice is able to document that a shorter intervat is representative for
local storm events during the sampling period, and the permittee obtains approval from the local DWQ
Recional Office.

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. 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
Pat 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.

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. For 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), 1 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

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. 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 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.

Inspection Summary:
Facility Description:
This facility is primarily engaged in the production of entry doors. The facility operates 6:00 a.m. through 11:00 p.m.,
Monday through Friday and Saturdays as needed. No vehicle maintenance or washing is conducted at the facility but
hazardous materials are handled at the facility. Detrex Corporation, Allied Waste, and Nesbit Oil are waste haulers for

ComplianceHistory:
The permitteelfacility does not have any prior compliance issues with the NC Division of Water Quality but on
September 12, 2007, Masonite Door Corporation was issued a City of Charlotte Notice of Violation for the discharge of
approximately 1,000 gallons of liquid Polyol resin to the ground surface.
Industrial Operations/City of Charlotte Stormwater Ordinance Review:
Eye Wash —
One eye wash sink located inside the building near the Line One Foaming Area was plumbed outside to the earthen
ground. The permittee shall properly plumb and remove all illicit connections.
Baghouse --
Particulate material from the baghouse was observed outside on a paved surface. The permittee should routinely
inspect and properly maintain the area to prevent stormwater contamination.
Paint Totes —
Four 300-gallon totes were observed outside on a paved surface and exposed to stormwater. Facility personnel
explained that the totes contain leftover paint and are set outside to dry out, then disposed. Dried paint residue was
observed on the outside of the totes. The permittee should consider storing the totes in a location not exposed to
stormwater.
Stormwater Pollution Prevention Plan (cont. from Page 4)
The facility houses an outside 12,000-gallon cyclopentane tank that sits within a concrete secondary containment
structure. Currently the drain valve for the secondary containment structure is kept open and is actuated by a
hydrocarbon monitoring system located inside the sump in the containment area. The facility's SPPP states that the
monitoring system and valve.actuator are maintained and tested in accordance with manufacturer's recommendations.
During the inspection facility staff explained that standing water inside the containment structure would ruin the sensor
on the monitoring system, which is expensive to replace.
Chemical research indicates that cyclopentane is a clear chemical compound with a petrol -like odor and a boiling point
of 49°C. The facility is in ongoing discussions with the Division of Water Quality to ensure the current system meets the
intent of the secondary containment requirements of General Permit NCG030000. The permit states that secondary
containment structures are to be controlled by a manually activated valve or other similar devices, which are to be
secured closed at all times with a locking mechanism. In addition, the permit requires that accumulated stormwater in
the containment area shall be at a minimum visually observed for color, foam, outfall staining, visible sheens and dry
weather flows prior to release of the accumulated stormwater.
The permittee should provide the Division with details regarding the reliability of the hydrocarbon sensor, the back-up
systems in place, the testing and maintenance procedures of the monitoring system and the frequency with which they
are completed to justify a departure from the requirements of the permit.

Comment: The Stormwater Pollution Prevention Plan (SPPP) general location map
did not include information on whether the receiving stream is 303(d) listed and/or if a
TMDL has been developed. The SPPP did not include documentation of the 914/07
release of 5,000 gallons of resin of which 1,000 gallons escaped secondary
containment and flowed onto the asphalt drive and grassed drainage Swale. The spill
did not reach surface waters.
The permittee could not provide documentation to support employee training. The
SPPP was reviewed and updated on 11/29/06, 3/18/08, and 2/16/09 and stormwater
facility inspections were conducted on 10/9/08, 11/12/08, 12116108, 1/2010909, and

Comment: The facility does not use any Total Toxic Organics (TTO) and therefore
testing for TTOs is not required. The permittee conducted analytical sampling on
6/21/04, 6/14106, 2/13/07, 5/28108, and 11125/08. On 11/25/08 the Total Suspended

Comment: Five storm drain outfails have been identified at the facility and the Division
of Water Quality granted representative outfall status on July 16, 2007.
Documentation has not been included for the annual evaluation for the presence of
non-stormwater discharges. On September 4, 2007, Mecklenburg County Water
Quality Program (MCWQP) staff reviewed the facility's SPPP and suggested to Mr. Jim
Martin, EHS Coordinator for Masonite, that the certification of non-stormwater discharge
be completed and signed.

Cyclopentane Containment
After further investigation of the Cyclopentane containment basin and the sensors in the area I have discerned the
following information.
There is a motorized valve on the basin release drain that has never been wired and is in the constant open position.
Behind the motorized valve there is a manual valve that is kept in the closed position at all times. The water in the
catch basin is released manually when it accumulates in the sump and gravity feeds to the drainage swale to the #4
outfall area_
An inspection form using the criteria outlined in the Storm Water Permit will be filled out each time the water
accumulates in the basin to determine its safe release.
The Sensors in the basin are explosive atmosphere detectors that are connected to the panel near the line one
operator station. If the sensors detect that there is a buildup of Cyclopentane in the containment area, the
Cyclopentane feed valve to the process is shut down and an alarm sounds in the panel.
These sensors do not control the Storm Water drainage valve.

Description of Issue
SPPP general location map did not include information on whether the receiving stream is 303(d)
listed and/or if a TMDL has been developed.
Remedial Action Taken
Section 303(d) of the Clean Water Act (CWA) requires states to develop a list of waters not
meeting water quality standards or which have impaired uses. Listed waters must be prioritized,
and a management strategy or total maximum daily load (TMDL) must subsequently be
developed for all listed waters.
The storm water from the Charlotte facility discharges into an unnamed tributary of McIntyre
Creek. McIntyre Creek is not listed on 303(d), and therefore does not have a TMDL established.
A statement has been added to the general location map in the SPPP stating that McIntyre Creek
is no 303(d) listed.

An updated General Location map is included in the site copy of the SWPPP.
