RE NCG06-Notice of Intent for SW Permit -Supplemental Information �ri�inF8 2Q15
To Whom It May Concern,
Enclosed Is the Notice of Intent document for New Belgium Brewery (NBB)
stormwater permit application. Multiple site drawings are provided, and this
document provides additional information about these drawings
The first two drawings display a general site overview of the manufacturing
facility. The first drawing is labelled Perkins + Will C-0 1 'Master Plan', and
provides the overall layout of the facility with site property lines. In addition,
total pervious and impervious square footage is provided under the
development data table at the top of the drawing The second drawing is
labelled Perkins + Will C-2 0 'Staking and Materials Plan Overall', and displays
the pervious and impervious areas
The next drawing shows the stormwater features associated with the site, and Is
printed on 11 x 17 paper Items displayed are runoff conveyance features,
location of stormwater outfalls, drainage areas, stormwater management
structures and material storage areas
An updated drawing is provided for the stormwater feature drawing, which
updates the layout of the bioswales across from the truck dock impervious area.
This drawing is number C14 and has a title of'Truck Court Storm System'
Instead of the stormwater sheet Flowing from the truck dock to a bioswale
located to the West, this liquid is now conveyed to pipes which discharge to a
bioswale on the NW side of the site This liquid then passes through another
bioswale before ultimately being discharged to the river
The final drawing is the county map with the facility location clearly marked on
the map. This drawing has the words Buncombe County' on the top, and is
dated 12/16/15

Mark,
The last paragraph in the below email identifies what substances require second containment For further clarification
and regulatory references see as follows
1) bulk storage of liquid materials including petroleum products - Liquid raw materials, manufactured
products, waste materials or by-products with a single above ground storage container having a
capacity of greater than 660 gallons or with multiple above
ground storage containers located in close proximity to each other having a total combined storage
capacity of greater than 1,320 gallons
2) Storage in any amount - Section 313 of Title III of the Superfund Amendments and Reauthorization Act
(SARA) water priority chemicals - A chemical or chemical category which
b Is listed in 40 CFR 372 65 pursuant to Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) of 1986, also titled the Emergency Planning and Community Rightto-
Know Act of 1986,
c Is present at or above threshold levels at a facility subject to SARA title III, Section 313 reporting
requirements, and
d Meets at least one of the following criteria
i Is listed in appendix D of 40 CFR part 122 on Table 11 (organic priority pollutants), Table
111 (certain metals, cyanides, and phenols) or Table IV (certain toxic pollutants and
hazardous substances),
u Is listed as a hazardous substance pursuant to section 311(b)(2)(A) of the CWA at 40 CFR
116 4, or
ui Is a pollutant for which EPA has published acute or chronic water quality criteria
3) storage in any amount of hazardous substances - Any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act
Mark, all this can be found in the definitions section of the Stormwater Permit I am attaching a copy of the
Food & Kindred General Stormwater permit (NCG060000) for your review I think this may be the SIC code
that you all are in? if not, let me know which SIC code you are and I will forward the correct general permit

Subject: RE Stormwater design question - New Belgium Buncombe
Mark,
Thank you for your inquiry and the opportunity to comment on this proposed design The proposed design appears to
be susceptible to operator error if GMPs are not followed Failure of GMPs could result in direct discharge of
NaOH, MgOH, or acid into receiving waters (the French Broad), which is very much a concern of ours Because you did
not mention any secondary containment in this area (except the sloped area in the unloading area), a stormwater drain
located in this unloading area would always be worrisome because of the potential for a chemical spill during unloading
To address these concerns, we would recommend that the unloading areas be covered to minimize the amount of
stormwater and that the stormwater drain be eliminated The process drain with a valve could be utilized to accept the
small amount of stormwater that is blown into this area If there is concern of spills going to the pretreatment facility
during unloading, the valve on the process pipe could be closed during unloading This would be the more
environmentally secure approach if feasible with your design considerations and constraints
If covering the unloading area and eliminating the stormwater drain in this area is not feasible, we would at the very
least recommend that the stormwater drain valve be kept closed at all times and only manually opened under similar
constraints used for Aboveground Storage tank (AST) bulk storage secondary containment in our general permits (see
below) By doing this, the sloped collection area acts as a secondary containment area with manual release only
Mark, again thanks for the opportunity to review and comment Because we are not familiar with the design details of
your process or pretreatment system, our recommendations may not be feasible However, if they are, your
consideration of our recommendations is appreciated
If you have any questions or would like to discuss, please let me know or give me a call We look forward to working
with you all and welcome you to North Carolina and Asheville
Thanks,

Secondary Containment Requirements and Records Secondary containment is
required for bulk storage of liquid materials including petroleum products, storage in any
amount of Section 313 of Title III of the Superfund Amendments and Reauthorization Act
(SARA) water priority chemicals, and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff A table or
summary of all such tanks and stored materials and their associated secondary containment
areas shall be maintained If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually activated
valves or other similar devices (which shall be secured closed with a locking mechanism)
Any stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, outfall staining, visible sheens and dry weather flow, prior to
release of the accumulated stormwater Accumulated stormwater shall be released if found
to be uncontaminated by any material Records documenting the individual making the

I r %
observation, the description of the9cumulated stormwater, and the date a0time of the
release shall be kept for a period of five (5) years For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC plan fully
compliant with the requirements of this permit may be used to demonstrate compliance
with this permit

Subject: Stormwater design question
I am an engineer with New Belgium working on design of our new brewery in Asheville
I got your name from Nick Ampe in our risk management group
We have a question regarding design that could impact stormwater and wanted your opinion and comments on it
If you are not the proper person to be calling can you please forward this on
We will have two locations at our brewery where we will be unloading chemical trucks
Each area will sloped sides and enough volume to hold more than the volume in the truck
We would like to use a double drain system similar to what we use at our Fort Collins brewery
The sloped collection area would have two drains
Drain 1 would go to the stormwater drain
Drain 2 would go to our process drains which will go to a pretreatment facility and then to the MSD
There would be GMP that our workers would be trained on that would mandate the process drain be plugged at all
times to allow stormwater to go to the stormwater drain
The procedure would also require the plug to be moved to the stormwater drain when a chemical truck is being
unloaded and returned to the process drain following unloading of the truck
Please let us know your thoughts on this system
The containment areas would not be covered
Chemicals would be bulk caustic and bulk MgOH and bulk acid
Thanks for any assistance you can give us

Subject: RE Stormwater design question
Hi Laura,
I concur It seems like this design and proposed operating procedure invite operator error, with potential impact to the
receiving water
As to stormwater regulation and permitting This facility would have an NPDES stormwater permit, and those
permits are essentially 'performance spec' regulations We would either use the General Permit NCG06 Food
and Kindred products, or if this facility presents risks that we think wouldn't be addressed by NCG06, we'd craft
an individual permit I don't think the General Permit, or our beginning template for an individual permit, would
include restrictions on how they conduct their operations We would Just have numerical benchmarks
for testing the stormwater discharge So, as to us prohibiting this design, I don't think that's the path for
us They can do it this way, and we have no authority to direct otherwise
As to prudent facility design They know their business and plant design needs, and we
don't Obviously However, some questions pop to mind
c Mr Fischer reports that the unloading areas will not be covered Why not? This is a brand new
plant He can design it any way he wants to If this is on the scale of a very large brewery, the cost of a
couple of shed roofs over the unloading areas would be inconsequential compared to aggregate site
construction costs
o Bulk NaOH, MgOH, and acid are worrisome chemicals if you consider an accidental direct discharge to
the receiving waters While these unloading areas do not qualify as AST Bulk Storage tank installations,
and so are not required to have secondary containment, from one perspective they do present a similar,
or maybe even greater risk, I think And so, I would at least reverse their operating logic to have the
storm drain plugged all the time, and only opened periodically under similar constraints used for AST
bulk storage secondary containment in our permits
o Breweries use a tremendous amount of water in the process I would expect a large amount of
wastewater, too Mr Fischer reports that the facility will have a pretreatment system before
wastewater discharge to the Asheville or Buncombe County MSD I don't know the design parameters
related to their on -site pretreatment facility, but it seems to me the more environmentally secure
approach would be to accept the little tiny bit of rainwater from the containment areas (compared to
the daily production wastewater volume) directly into their process pretreatment system Then there is
no need for plugging/unplugging Of course, a big slug of 50% NaOH directly into their pretreatment
system may be problematic But, I'm more concerned about a big slug of 50% caustic into the waters of
North Carolina
o As an engineer, I Just distrust 'training and operating procedures' compared to concrete physical
solutions
o So my first reaction without broader knowledge of their facility operating needs is that the best design
here would be to put a roof over the unloading areas and have a direct pipe to the pretreatment system
with a valve The valve can stay open all the time, so that any windblown rain goes to the pretreatment
system lFt—hey're worried about a slug of concentrated acid or base entering the pretreatment system,
their training and operating procedures can include having the truck driver close the valve before he

+ L
unloads Any spills 11be assessed for impact on the pretreatmetsystem, and can be released if
minor, or addressed as a major spill if necessary

Ken and Bethany,
What do you think of this design? The biggest drawback that I can see with this system is that it will be rone to
operator error (manual plugging and unplugging of the correct drain dependent on the operation) Yotfeedback is
always appreciated
Thanks and have a great weekend,

Subject: Stormwater design question
I am an engineer with New Belgium working on design of our new brewery in Asheville
I got your name from Nick Ampe in our risk management group
We have a question regarding design that could impact stormwater and wanted your opinion and comments on it
If you are not the proper person to be calling can you please forward this on
We will have two locations at our brewery where we will be unloading chemical trucks
Each area will sloped sides and enough volume to hold more than the volume in the truck
We would like to use a double drain system similar to what we use at our Fort Collins brewery

The sloped collection area would halewo drains 0
Drain 1 would go to the stormwater drain
Drain 2 would go to our process drains which will go to a pretreatment facility and then to the MSD
There would be GMP that our workers would be trained on that would mandate the process drain be plugged at all
times to allow stormwater to go to the stormwater drain
The procedure would also require the plug to be moved to the stormwater drain when a chemical truck is being
unloaded and returned to the process drain following unloading of the truck
Please let us know your thoughts on this system
The containment areas would not be covered
Chemicals would be bulk caustic and bulk MgOH and bulk acid
Thanks for any assistance you can give us

Permit No NCG060000
PART I — INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to have facilities covered by this General Permit must register with the Division
of Water Quality (DWQ) by the filing of a Notice of Intent (NOI) and applicable fees. The NO[ shall be
submitted and a certificate of coverage issued prior to any point source discharge of stormwater
associated with industrial activity to the surface waters of the state
Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H
0100, stating the reasons supporting the request Any application for an individual permit should
be made at least 180 days prior to commencement of discharge
This General Permit does not cover activities or discharges covered by an individual NPDES permit
until the individual permit has expired or has been revoked. Any person conducting an activity
covered by an individual permit but which could be covered by this General Permit may request
that the individual permit be revoked and coverage under this General Permit be provided
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 Any owner or operator wishing to obtain a No Exposure Exclusion
must submit a No Exposure Certification Notice of Intent (NO1) form to the Division, must receive
approval by the Division, must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit, and must recertify the No Exposure Exclusion annually
Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Load (TMDL) for pollutants for stormwater is established A TMDL sets a pollutant -loading
limit that affects a watershed, or portion of a watershed, draining to a specific impaired water For
discharges to watersheds affected by a TMDL, coverage under this permit may depend on the
facility demonstrating it does not have reasonable potential to violate applicable water
quality standards for those pollutants as a result of discharges. If DWQ determines that
discharges have reasonable potential to cause water quality standard violations, the facility shall
apply for an individual permit 180 days prior to the expiration date of this General Permit. Once
that individual permit is effective, the facility will no longer have coverage under this General
Permit Note that the permtttee must identify impaired waters (scheduled for TMDL development)
and waters already subject to a TMDL in the Site Plan, as outlined in the Stormwater Pollution
Prevention Plan, Part II, Section A
During the period beginning on the effective date of the permit and lasting until expiration, the
permtttee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified in this permit
Part I Page 1 of 2

PermitNo NCG060000
SECTION B. PERMITTED ACTIVITIES
Until coverage under this permit expires or is modified or revoked, the permittee is authorized to
discharge stormwater to the surface waters of North Carolina, or to a separate storm sewer system,
which has been adequately treated and managed in accordance with the terms and conditions of
this General Permit
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or approval
The discharges allowed by this General Permit shall not cause or contribute to violations of
Water Quality Standards.
This permit does not relieve the permittee's responsibility for compliance with any other applicable
federal, state, or local law, rule, standard, ordinance, order, or decree

PART II — MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Pian (SPPP) The
SPPP shall be maintained on site unless exempted from this requirement by the Division The SPPP
is public information in accordance with Part III, Standard Conditions, Section E, paragraph 3 of this
permit The SPPP shall include, at a minimum, the following items
1 Site Overview The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may be expected to contribute to contamination of stormwater
discharges The Site Overview shall contain the following
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters, the
name of the receiving waters to which the stormwater outfalls discharge, or if the discharge
is to a municipal separate storm sewer system, the name of the municipality and the
ultimate receiving waters, and accurate latitude and longitude of the points of stormwater
discharge associated with industrial activity. The general location map (or alternatively the
site map) shall identify whether any receiving waters are impaired (on the state's 303(d)
list of impaired waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices A narrative description of the potential pollutants that could be expected to be
present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict the site property boundary, the
stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands,
industrial activity areas (including storage of materials, disposal areas, process areas,
loading and unloading areas, and haul roads), site topography and finished grade, all
drainage features and structures, drainage area boundaries and total contributing area for
each outfall, direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, stormwater Best Management Practices (BMPs), and impervious
surfaces The site map must indicate the percentage of each drainage area that is
impervious, and the site map must include a graphic scale indication and north arrow
(d) A list of significant spills or leaks of pollutants during the previous three (3) years and
any corrective actions taken to mitigate spill impacts
(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges. The
certification statement will be signed in accordance with the requirements found in Part III,
Standard Conditions, Section B, Paragraph 3
Part 11 Page 1 of 12

Permit No NCG060000
2. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or
minimize the stormwater exposure of significant materials, including structural and
nonstructural measures. The Stormwater Management Strategy, at a minimum, shall
incorporate the following
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes to rainfall and run-on flows. Wherever practical, the permittee
shall prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations In areas where elimination of exposure is not
practical, this review shall document the feasibility of diverting the stormwater run-on
away from areas of potential contamination
(b) Secondary Containment Requirements and Records Secondary containment is
required for bulk storage of liquid materials including petroleum products, storage in au
amount of Section 313 of Title III of the Superfund Amendments and Reauthorization Act
(SARA) water priority chemicals; and storage in anv amount of hazardous substances in
order to prevent leaks and spills from contaminating Stormwater runoff A table or
summary of all such tanks and stored materials and their associated secondary containment
areas shall be maintained If the secondary containment devices are connected to
Stormwater conveyance systems, the connection shall be controlled by manually activated
valves or other similar devices (which shall be secured closed with a locking mechanism)
Any stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, outfall staining, visible sheens and dry weather flow, prior to
release of the accumulated stormwater Accumulated stormwater shall be released if found
to be uncontaminated by any material Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time of the
release shall be kept for a period of five (S) years For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC plan fully
compliant with the requirements of this permit may be used to demonstrate compliance
with this permit
(c) BMP Summary. A listing of site structural and non-structural Best Management Practices
(BMPs) shall be provided The installation and implementation of BMPs shall be based on
the assessment of the potential for sources to contribute significant quantities of pollutants
to stormwater discharges and on data collected through monitoring of stormwater
discharges. The BMP Summary shall include a written record of the specific rationale for
installation and implementation of the selected site BMPs The BMP Summary shall be
reviewed and updated annually
3 Spill Prevention and Response Procedures The Spill Prevention and Response Procedures
(SPRP) shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility Facility personnel responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
acknowledging their responsibilities for the plan A responsible person shall be on -site at all
times during facility operations that have the potential to contaminate stormwater runoff
through spills or exposure of materials associated with the facility operations The SPRP must
be site stormwater specific Therefore, an oil Spill Prevention Control and Countermeasure
plan (SPCC) may be a component of the SPRP, but may not be sufficient to completely address
the stormwater aspects of the SPRP The common elements of the SPCC with the SPRP maybe
incorporated by reference into the SPRP
Part 11 Page 2 of 12

Permit No NCG060000
4 Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
and good housekeeping program shall be developed and implemented. The program shall
address all stormwater control systems (if applicable), stormwater discharge outfalls, all on -site
and adjacent surface waters and wetlands, industrial activity areas (including material storage
areas, material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The program
shall establish schedules of inspections, maintenance, and housekeeping activities of
stormwater control systems, as well as facility equipment, facility areas, and facility systems
that present a potential for stormwater exposure or stormwater pollution where not already
addressed under another element of the SPPP Inspection of material handling areas and
regular cleaning schedules of these areas shall be incorporated into the program Timely
compliance with the established schedules for inspections, maintenance, and housekeeping
shall be recorded and maintained in the SPPP
Facility Inspections Inspections of the facility and all stormwater systems shall occur as part
of the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-
annual schedule, once during the first half of the year (January to June), and once during the
second half (July to December), with at least 60 days separating inspection dates (unless
performed more frequently than semi-annually) These facility inspections are different from,
and in addition to, the stormwater discharge characteristic monitoring at the outfalls required
in Part II B, Q and D of this permit.
Employee Training Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for spill response and
cleanup, preventative maintenance activities, and for any of the facility's operations that have
the potential to contaminate stormwater runoff. The facility personnel responsible for
implementing the training shall be identified, and their annual training shall be documented by
the signature of each employee trained
7 Responsible Party The SPPP shall identify a specific position or positions responsible for the
overall coordination, development, implementation, and revision of the SPPP, Responsibilities
for all components of the SPPP shall be documented and position assignments provided
SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there
is a change in design, construction, operation, site drainage, maintenance, or configuration of
the physical features which may have a significant effect on the potential for the discharge of
pollutants to surface waters All aspects of the SPPP shall be reviewed and updated on an
annual basis. The annual update shall include
(a) an updated list of significant spills or leaks of pollutants for the previous three (3)
years, or the notation that no spills have occurred (element of the Site Overview),
(b) a written re -certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview),
(c) a documented re-evaluation of the effectiveness of the on -site stormwater BMPs
(BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response status
The permittee shall use the Division's Annual Summary Data Monitoring Report
(DMR) form, available from the Stormwater Permitting Unit's website (See
'Monitoring Forms' here httl2 //nortal,ncdenr org/web/wq/ws/su/npdessw)

The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit Within 30 days of such notice, the permittee shall submit
a time schedule to the Director for modifying the SPPP to meet minimum requirements The
permittee shall provide certification in writing (in accordance with Part 111, Standard
Conditions, Section B, Paragraph 3) to the Director that the changes have been made
9. SPPP Implementation The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs to prevent contaminants from entering surface waters via
stormwater Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to employees,
including the log of the sampling data and of actions taken to implement BMPs associated with
the industrial activities, including vehicle maintenance activities Such documentation shall be
kept on -site for a period of five (5) years and made available to the Director or the Director's
authorized representative immediately upon request

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 measureable storm event at each stormwater
discharge outfall (SDO), Only SDOs discharging stormwater associated with industrial activity must
be sampled (See Definitions)
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 See Definitions

1 Maintain semi-annual analytical monitoring throughout the permit renewal process (unless other
provisions of this permit prompt monthly sampling)
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period "No discharge" from an outfall or
inability to collect a sample because of adverse weather conditions during a monitoring period, for
example, does not constitute failure to monitor, as long as it is properly reported
The permittee shall compare monitoring results to the benchmark values in Table 3 The benchmark
values in Table 3 are not permit limits but should be used as guidelines for the permittee's Stormwater
Pollution Prevention Plan (SPPP) Exceedances of benchmark values require the permittee to increase
monitoring, increase management actions, increase record keeping, and/or install stormwater Best
Management Practices (BMPs) in a tiered program See below the descriptions of Tier One, Tier Two,
and Tier Three response actions below In the event that the Division releases the permittee from
continued monthly monitoring under Tier Three, DWQ's release letter remains in effect through
subsequent reissuance of this permit, unless the release letter provides for other conditions or

monitoring periods through the end of this permitting cycle
2 Grab samples shall be collected within the first 30 minutes of discharge
3 Sample Location Samples shall be collected at each stormwater discharge outfall (SDO) that discharges
stormwater runoff from area(s) where vehicle maintenance activities occur
4 For each sampled measureable storm event the total precipitation must be recorded An on -site or local
rain gauge reading must be recorded Where isolated sites are unmanned for extended periods of time, a
local rain gauge reading may be substituted for an on -site reading
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period, as provided in Part 11 Section B
Monitoring results shall be compared to the benchmark values in Table S. The benchmark values
in Table 5 are not permit limits but should be used as guidelines for the permittee's Stormwater
Pollution Prevention Plan (SPPP) Exceedances of benchmark values require the permttiee to
increase monitoring, increase management actions, increase record keeping, and/or install
stormwater Best Management Practices (BMPs), as provided in Part II Section B. In the event that
the Division releases the permtttee from continued monthly monitoring under Tier Three, DWQ's
release letter remains in effect through subsequent reissuance of this permit, unless the release
letter provides for other conditions or duration

SECTION D: STORMWATER DISCHARGES: QUALITATIVE MONITORING
REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assess new sources of stormwater pollution Qualitative monitoring of
stormwater outfalls must be performed during a measurable storm event
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status Qualitative monitoring shall be performed semi-annually as specified
in Table 6, and during required analytical monitoring events (unless the permittee is required to
perform further qualitative sampling per the Qualitative Monitoring Response, below). Inability
to sample because of adverse weather conditions must be documented in the SPPP and recorded on
the DMR (see Adverse Weather to Definitions) Only SDOs discharging stormwater associated with
industrial activity must be monitored (See Definitions)
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the discovery.
This documentation will be maintained with the SPPP

2 Monitoring Location Qualitative monitoring shall be performed at each stormwater discharge outfall
[SDO) regardless of representative outfall status
A minimum of 60 days must separate monitoring dates, unless additional sampling has been
instituted as part of other analytical monitoring requirements in this permit
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or that
significant stormwater contamination is present, the permittee shall investigate potential causes, evaluate
the feasibility of corrective actions, and implement those corrective actions within 60 days, per the
Qualitative Monitoring Response, below. A written record of the permittee's investigation, evaluation,
and response actions shall be kept in the Stormwater Pollution Prevention Plan
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, assessing new sources
of stormwater pollution, and prompting the permittee's response to pollution If the permittee
repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if
the discharge causes or contributes to a water quality standard violation, DWQ may but is not
limited to:
• require that the permittee revise, increase, or decrease monitoring frequency for some or
all parameters (analytical or qualitative),
• require the permittee to install structural stormwater controls,
• require the permittee to implement other stormwater control measures,
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters, or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion
