Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. TSS has been added to the analytical monitoring parameters of this permit. This is because the stream being
impaired due to turbidity. Also, COD has been added; while Ammonia has been removed.
2. pH has been added to the analytical monitoring requirements per the Division's revised monitoring
strategy.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B. The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the. permittee must submit a monitoring report indicating "No Flow'
within 30 days of the end of the six-month sampling period. Additionally, samples must.be taken a
minimum of 60 days apait, as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record keehuig,
and/or install storm -water Best Management Practices (BMPs) in a tiered program. If the sampling results
are above a benchmark value, or outside of the benchmark range, for any parameter at any outfall then the
facility shall follow the,Tier 1 guidelines which require a facility inspection within two weeks and
implementation of a mitigation plan within two months. If during the term of this permit, the sampling
results are above the benchmark values, or outside of the benchmark range, for any specific parameter at a
specific discharge outfall two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines
which require a repetition of the steps listed for Tier 1 and also immediately institute monthly monitoring
for all parameters at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples.
5. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status. " -

Permit No. NCS000390
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables'l, 4, and
5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter
is in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring. This requirement appears in all Individual Stormwater permits, however it only
applies to facilities that do vehicle maintenance. If the facility begins vehicle maintenance during the
permitted timeframe then the requirements shall apply.
Other permit changes:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in
each outfall. The map requirements are stated, more explicitly. And, the site Plan must"contain a list of
significant spills that have. occurred in the past three years and also must certify that the outfalls have been
inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided ht Parl II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A.
More details regarding secondary containment are provided.
3. Additional requirements•for the Stormwater Pollution Prevention Plan have been specified in Part II Section
A. The plan must also be updated annually to include a list of significant spills and to certify that the
outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements.
Additional information is provided in Part I Section A.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft. Comments
should be sent to the address listed at the bottom of this page. If no adverse comments are received from the
public or from you, this permit will likely be issued in about two months.

3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) 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 may be incorporated by reference into the
SPRP.
d . Preventative Maintenance. and Good housekeeping Program. A;preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, 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

program shall establish schedules of inspections, inaintenatice, aiid 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.
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 in writing and maintained
in the SPPP.
5. 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. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee trained.
6. Responsible Party. The Stonnwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the flan. Responsibilities for all components of the flan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the Stormwater
Pollution Prevention Plan shall be reviewed and updated on an annual basis. The annual
update shall include an updated list of significant spills or leaks of pollutants for the
previous three years, or the notation that no spills have occurred. The annual update shall
include re -certification that the stormwater outfalls have been evaluated for the presence
of non-stormwater discharges. Each annual update shall include a re-evaluation of the
Part II Page 3 of 10

effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management
Plan.
The Director may notify the permittee when the Plan 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 Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. 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
required in Part II B and C of this permit.
9. Implementation. The permittee shall
shall include documentation of all in
activities, and training provided to e
of actions taken to
vehicle maintenani
five years and mad
immediately upon

Permit No. NCS000390
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

the permittee has submitted the appropriate paperwork for a renewal permit before the submittal deadline, the
permittee will be considered for a renewal application. The applicant must continue semi-annual monitoring until
the renewed permit is issued. See Table 2 for schedule of monitoring periods through the end of this permitting
cycle.
2 If the stormwater runoff is controlled by a stormwater detention pond, a grab sample of the discharge from the
pond shall be collected within the first 30 minutes of discharge.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative
outfall status has been granted.
4 For each sampled representative storm event the total precipitation must be recorded. An on -site rain gauge or
local rain gauge reading must be recorded.

Central Office Review Summary:
1. General Observations:
• The entire site drains to a single outfall (wet detention pond) located on the west side of the property.
• Unloading/loading area and processing is all under cover.
• Secondary containment for tank farm.
• This site looks like a good candidate for No Exposure. Will the RO provide comments on this after
seeing the site first hand?
• List of BMPs utilized onsite not included and marked "N/A" on the renewal application. This is not the
case, and is required per the permit and the renewal application. This info should be in their SPPP.
2. Impairment: 303(d) lists this stream segment as impaired for biological integrity, Basinwide Plan states that the
stream is also impaired due to turbidity.
3. Threatened and Endangered: None.
4. Industrial Changes Since Previous Permit: None.
5. Analytical Monitoring Notes: None submitted as required with the renewal application; marked "N/A" on the
renewal application — but this is not the case. The previous permit term required a minimum of 7 samplings of
Ammonia, NH3 as N. None were done as required because the permittee stated that the pond had not ever
discharged. I told them that they still must still submit a DMR stating no flow if that is the case so that it is
documented. Does the RO know of the history as to why Ammonia was in the permit to begin with?
o The EPA MSGP (for this SIC code) requires monitoring for COD, TSS, Aluminum, Copper, Iron, Lead,
and Zinc. Most of these metals are not a concern at this site. They do internal required testing of the
used oil to be sure they meet limits of certain metals (arsenic, cadmium, chromium, lead, and halofens) in
order to resell the recycled oil.
6. Qualitative Monitoring Notes: None submitted as required with the renewal application. Received later via fax
after requesting monitoring data. Done as required. About half the time there was no discharge recorded from
the detention pond. Sometimes noted a brown to slight green color; algae; and semi -clear.
Revised Permit Recommendations: Analytical Monitoring:
1. Add TSS to the monitoring due to the stream impairment for turbidity and MSGP. Add COD based on the
MSGP. Remove Ammonia from monitoring because there was no identified source or reason to suspect problem.
2. pH has been added to the analytical monitoring requirements per our revised monitoring strategy.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs during
the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days of the
end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart, as
specified in Table 2,
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or install
stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall follow
the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a mitigation plan
within two months. If during the term of this permit, the sampling results are above the benchmark values, or
outside of the benchmark range, for any specific parameter at a specific discharge outfall two times in a row
(consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of the steps listed for
Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall where a sampling
result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
Page 3 of 5

NCS000390
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements Ibr the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater management
controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information is
provided in Part I Section A.
Discussions with permittee: Bill Henkel & Anne Pifer, 704-455-1333, 1/23/09 & 2/6/09
Q: Analytical samples for Ammonia? None submitted with renewal application.
a. ANSWER: Will be submitting. None performed since there was never a discharge.
2. Q: Qualitative results? None submitted with renewal application.
a. ANSWER: Will be submitting.
3. Q: Is the maintenance building and wash area for vehicle maintenance?
a. ANSWER: They do wash trucks there, but vehicle maintenance is now done offsite.
4. Q: Name and contact change again?
a. ANSWER: Thomas is no longer with the company; new permit contact is Bill Henkel.

controlled by manually activated valves or other similar devices (which shall be
secured closed with a locking mechanism), and 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 the material stored within the contaiiunent area. 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 years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) 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 data collected

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

RE: Separation of Hydrocarbon Recovery Services, Inc. from Siemens Water
Technologies Corp.
NPDES # NCS000390
Dear Sir/Madam:
On August 31, 2006, you were notified that the legal entity U.S. Filter Recovery Services
(Mid -Atlantic), Inc. was merged into its immediate parent company, Siemens Water
Technologles Corp. As a result, U.S. Filter Recovery Services (Mid -Atlantic), Inc.
ceased to exist, and Siemens Water Technologies Corp. succeeded by operation of law
to all of the former U.S. Filter Recovery Services (Mid -Atlantic), Inc.'s assets and
liabilities.
Effective October 1, 2007, Siemens Water Technologies Corp. is separating the assets
of the aforementioned facilities into the legal entity Hydrocarbon Recovery Services, Inc.,
which is a direct, wholly -owned, subsidiary of Siemens Water Technologies Corp. No
change of ownership is occurring and there will be no change in facility personnel or
operations as a result of transferring these business assets into a wholly -owned
subsidiary.
As a' result of this separation, Hydrocarbon Recovery Services, Inc. will succeed to, and
become the new permittee under NPDES #NCS000390 currently issued to Siemens
Water Technologies Corp. I understand that the permit[s] will remain in effect and its
[their] status will not otherwise be affected by the separation. Please notify me at your
earliest opportunity if this is not the case. Thank you for your attention to this request.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan 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 water(s) to which the
stormwater outfall(s) discharges, 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 point(s) of discharge.
(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.
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous 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 certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 3.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
Part II Page 1 of 6

Permit No. NCS000390
(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 stormwater. 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, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
cut►t,ected directly to stuiiriwate l Conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and 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
uncontaiiunated by the material stored within the containment area. 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 years.
(c) BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. 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, a SPCC plan maybe 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 may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
Part II Page 2 of 6

Permit No. NCS000390
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan 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 Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the
spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part II of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
log of the sampling data and of activities 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 years and made available to the Director or his
authorized representative immediately upon request.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
iepiesetilalive outfall status and shall be performed as specified below in Table 3. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls does not need to be performed during
a representative storm event.
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 Stormwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per year, once in the spring (April - June) and
once in the fall (September - November).

SECTION D: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS
Facilities which have any vehicle maintenance activity occurring on -site which uses more than
55 gallons of new motor oil per month when averaged over the calendar year shall perform
analytical monitoring as specified below in Table 4. This monitoring shall be performed at all
outfalls which discharge stormwater runoff from vehicle maintenance areas.
All analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of 7 analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO) which discharges stormwater runoff from
vehicle maintenance areas. The permittee shall complete the minimum 7 analytical samplings in
accordance with the schedule specified in Table 2 (Part H, Section B).

Footnotes:
I Measurement Frequency: Once per year during years 1, 2, and 3 of the permit term. Each quarter during the 4"
year of the permit term. A year is defined as the 12 month period beginning on the month and day of issuance of
the Permit. See Table 2 for schedule of monitoring periods.
2 If the stormwater runoff is controlled by a stormwater detention pond, a grab sample of the discharge from the
pond shall be collected within the fast 30 minutes of discharge. If the detention pond discharges only in response
to a storm event exceeding a ten year design storm, then no analytical monitoring is required and only qualitative
monitoring shall be performed.
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 Total flow shall be; (a) measured continuously, (b) calculated based on the amount of area draining to the outfall,
the amount of built -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the measurement
of flow at 20 minute intervals during the rainfall event. Total precipitation and duration of the rainfall event
measured shall result from the sampled representative storm event.
