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 Plan
(SPPP). The SPPP shall be maintained on site. 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 Plan. The site plan 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 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 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 discharge. The general location map (or alternatively
the site map) shall identify whether each receiving water is impaired (on the state's
303(d) list of impaired waters) or 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.
Part II Page 1 of 12

Permit No. NCS000057
(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.
2. Stormwater Management Plan. The stormwater management plan 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 plan, 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, the stormwater management plan 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; 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 substancesin 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 (5) years.
(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.
Part II Page 2 of 12

Permit No. NCS000057
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 responsible for implementing the SPRP shall
be. identified in a written list incorporated into the SPRP and signed and slated 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.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed and implemented.
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 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.
S. 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.
6. 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.
7. SPPP Amendment. 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:
Part Il Page 3 of 12

Permit No. NCS000057
(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
Plan);
(b) a Written re -certification that the stormwater outfalls have been evaluated f or
the presence of non-stormwater discharges (element of the Site Plan);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater
BMPs (BMP Summary element of the Stormwater Management Plan).
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 III, Standard Conditions, Section B, Paragraph 3) 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, C, and D of this permit.
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.

Permit No. NCS000057
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).
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.

Footnotes:
1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit.
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 immediately institutes monthly
monitoring for all stormwater parameters. After six (6) months of monthly monitoring,
the permittee may return to a semi-annual sampling monitoring schedule, unless DWQ
requires continued monthly monitoring or benchmark exceedances prompt a "Tier Two"
response. "No discharge" from an outfall during a monitoring period does not constitute a
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.
Total Recoverable Copper (Cu) and Zinc (Zn) are not subject to triggering the
increased monitoring requirements of Tier Two and Tier Three. Refer to Part II,

During the term of this permit, if the valid sampling results required for the permit monitoring periods
exceed the benchmark value, or are outside the benchmark range, for any specific parameter at any
specific outfall on four occasions, the permittee shall notify the DWQ Regional Office Supervisor in
writing within 30 days of receipt of the fourth analytical results. DWQ may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for the
remainder of the permit;
• 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.
This site discharges to impaired waters experiencing problems with copper, turbidity, and
biological integrity. If a Total Maximum Daily Load (TMDL) is approved for this segment of
Rocky River, the permittee may be required to monitor for the pollutant(s) of concern in
the future and submit results to the Division of Water Quality. The Division will consider
the monitoring results in determining whether additional BMPs are needed to control the
pollutant(s) of concern to the maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the Stormwater Pollution Prevention Plan.

SECTION C: 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 4, 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 due to adverse weather conditions must be
documented in the SPPP and recorded on the DMR (see Adverse Weather in 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.

(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.
Part 11 Page 9 of 12

Permit No. NCS000057
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 the monitoring frequency
(analytical or qualitative) for the remainder of the permit;
• 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.
SECTION D: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS
Facilities that 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 S. All analytical
monitoring shall be performed during a measureable storm event at all stormwater
discharge outfalls (SDOs) that discharge stormwater runoff from vehicle maintenance areas,
and in accordance with the schedule presented in Table 2 (Section B).

Footnotes:
1 Measurement Frequency: Twice per year during a measureable storm event, until either another permit
is issued for this facility or until this permit is revoked or rescinded. See Table 2 for schedule of
monitoring periods through the end of this permitting cycle.
2 Grab samples shall be collected within the first 30 minutes of discharge.
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.
Monitoring results shall be compared to the benchmark values in Table 6. The benchmark
values in Table 6 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), as provided in Part
11 Section B.

SECTION E: MANDATORY BEST MANAGEMENT PRACTICIES (BMPS)
The Permittee shall implement the following BMPs at this facility and shall include these
BMPs in the facility's SPPP:
1. The Permittee shall ensure entryways and loading/unloading areas near
manufacturing areas where copper exposure could occur are cleaned -up after use,
and that cleaning procedures are conspicuously posted within the affected work
areas. Any spills of material shall be cleaned -up by the end of the work shift, or
before if rainfall is expected prior to the end of the work shift.
2. The Permittee shall ensure routine evaluations by employee task groups of BMPs
intended to reduce copper and zinc exposure and shall identify practices or areas in
need of improvement.
Part Il Page 11 of 12

Permit No. NCS000057
3. The Permittee shall implement BMPs to reduce copper and zinc exposure, including
but not limited to: storing empty drums/totes/bales under cover and requiring
clean-up resulting from handling and storing of the powdered, liquid, and scrap
copper and zinc materials. For BMPs that have already been implemented, the
Permittee shall ensure those practices are maintained as long as they effectively
reduce copper and zinc exposure.
4. The Permittee shall devise a Monitoring Plan for sampling runoff from segregated
areas (for example, the roof drains and loading/unloading areas) to determine
where the primary contributions of copper and zinc to stormwater occur at the site.
The permittee may also include performing upstream and downstream monitoring
during rain events of the receiving stream to help identify to what extent the facility
may be contributing to the stream's impairment for copper. This Monitoring Plan
shall be submitted to DWQ for review and approval within four months of the
effective date of this permit [by September 1, 2012]. The Monitoring Plan should
require sampling (grab samples) be conducted during measurable storm events. In
addition to other parameters the Permittee deems useful, the Permittee shall
analyze copper and zinc concentration and estimate flow volume for each sampled
event. If averages will be used, the plan should include criteria about how many
samples are required. If the Permittee will evaluate the proportion of contribution
to the total mass of copper and zinc in runoff from the entire site, measurements
should be taken concurrently at stormwater discharge outfalls. Revisions to the
Monitoring Plan shall not require a revision to the Stormwater Permit. Any revision
of the Monitoring Plan after the initial review and approval of DWQ shall be
accomplished by mutual agreement between DWQ and the Permittee.
5. For areas the Permittee has determined to be primary contributions to copper
and/or zinc in runoff from this facility, either through the above Monitoring Plan or
by other means, the Permittee shall assess BMPs intended to reduce copper and zinc
release and exposure from industrial activities, reduce other sources of copper and
zinc contamination, and/or capture and treat the runoff with engineered controls.
The Permittee shall establish a schedule to implement selected BMPs and shall
submit a status report to DWQ outlining progress two and a half years following
the effective date of this permit [by November 30, 2014]. The BMPs assessment
and recommendations may focus on copper and zinc sources attributable to
industrial activities and materials, but the report should list any other influences
that are suspected to, or were determined to, contribute significant amounts of
copper and zinc to the stormwater discharge.

minimum detection and reporting levels and all data generated must be reported down to the
minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below permit discharge
requirements, then the most sensitive (method with the lowest possible detection and reporting
level) approved method must be used.
5. Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that
are required to be sampled, the permittee may petition the Director for representative outfall status.
If it is established that the stormwater discharges are substantially identical and the permittee is
granted representative outfall status, then sampling requirements may be performed at a reduced
number of outfalls.
6. Records Retention
Visual monitoring shall be documented and records maintained at the facility along with the
Stormwater Pollution Prevention Plan. Copies of analytical monitoring results shall also be
maintained on -site. The permittee shall retain records of all monitoring information, including

permittee must take a substitute sample or perform a visual assessment during the next qualifying
storm event. Documentation of an adverse event (with date, time and written narrative) and the
rationale must be included with your SPPP records. Adverse weather does not exempt the permittee
from having to file a monitoring report in accordance with the sampling schedule. Adverse events
and failures to monitor must also be explained and reported on the relevant DMR.
