PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of Energy,
Mineral, and Land Resources by the filing of a Notice of Intent (NOI) and applicable fees. The NOI
shall be submitted and a certificate of coverage issued prior to any discharge of stormwater
associated with industrial activity that has a point source discharge 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until the individual permit has expired or has been revoked.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
from permitting must submit a No Exposure Certification NOI 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 discharges is established. A TMDL sets a
pollutant -loading limit that affects a watershed, or portion of a watershed, draining to an impaired
water. For stormwater 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
the Division 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 permiee must identify impaired waters
(scheduled for TMDL development) and waters already subject to a TMDL in the Site Overview, as
outlined in the Stormwater Pollution Prevention Plan (SPPP), Part II, Section A.1. A list of approved
TMDLs for the state of North Carolina can be found at
http://portal.ncdenr.org/web/wg/Us/mtu/tmdl.

Permit No. NCG190000
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system which has been
treated and managed in accordance with the terms and conditions of this General Permit and the
requirements of the permittee's Certificate of Coverage (COC).
The permittee's COC is hereby incorporated by reference into this General Permit. Any violation of
the COC is a violation of this General Permit and subject to enforcement action as provided in the
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 stormwater discharges allowed by this General Permit shall not cause or contribute to
violations of Water Quality Standards.
This General Permit does not authorize discharges determined by the Division to be wastewaters.
This permit does not relieve the permittee from responsibility for compliance with any other
applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree.

PART I1 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 unless exempted from this requirement by the Division. The SPPP
is public information in accordance with Part III, 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 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; 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. In addition, the following
industrial activity areas must also be identified on the site map: fueling, engine maintenance
and repair, vessel maintenance and repair, washing, painting, sanding, blasting, welding,
and metal fabrication.
(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. If non-
stormwater discharges are present, the permittee shall identify the source and record whether
Part II Page 1 of 10

Permit No. NCG 190000
the discharge is otherwise permitted (by rule or a different permit). The permittee shall
evaluate the environmental significance of the non-stormwater discharges and include a
summary written record with the certification. The certification statement and summary
written record shall be retained with the SPPP, and shall be dated and signed in accordance
with the requirements found in Part III, Section B, paragraph S.
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 runoff 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 runoff 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 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
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. For the purposes of effective stormwater
pollution prevention the SPPP is intended to be broader and more comprehensive than a
federal oil Spill Prevention, Control, and Countermeasure Plan (SPCC). For facilities subject
to a federal SPCC plan, any portion of the federal 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
Part II Page 2 of 10

Permit No. NCG 190000
acknowledging their responsibilities for the procedures. A responsible person shall be on -site
at all times during facility operations that have increased 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. Solvent Management Plan. The Solvent Management Plan shall be incorporated as a separate
chapter into the Stormwater Pollution Prevention Plan (SPPP). The Solvent Management Plan shall
include an annually updated and quantified inventory of the solvents present on site during the
previous three years; a narrative description of the facility locations and uses of the solvents, the
method of disposal including quantities disposed on -site and off -site; and the management
procedures and engineering measures for assuring that solvents do not spill or leak into
stormwater. If solvents are not stored or used onsite, then the owner must certify that in the SPPP.
DEMLR may at its discretion require submittal, review, and approval of the Solvent Management
Plan. The discharger shall include the following signed certification statement on each discharge
monitoring report: "Based upon my inquiry of the person or persons directly responsible for
managing compliance with the permit requirement for managing solvents, I certify that to the best
of my knowledge and belief, no leak, spill, or dumping of concentrated solvents into the stormwater
or onto areas which are exposed to rainfall or stormwater runoff has occurred since filing the last
discharge monitoring report. I further certify that this facility is implementing all the provisions of
the Solvent Management Plan included in the Stormwater Pollution Prevention Plan."
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.
6. 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, C, and D of this permit.
7. 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 annual training shall be documented by
the signature and printed or typed name of each employee trained. Additional required
training items include: used oil management, spent solvent management, disposal of spent
Part II Page 3 of 10

Permit No. NCG 190000
abrasives, disposal of vessel wastewaters, fueling procedures, sanding, painting and blasting
procedures, and used battery management.
8. 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.
9. SPPP Amendment and Annual Update. All aspects of the SPPP shall be reviewed on an
annual basis. 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. The annual update shall include at a minimum:
(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 Program's website (See 'Monitoring
Forms' here: http://portal.ncdenr.org/web/lr/npdes-stormwater).
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, Section B,
Paragraph 5) to the Director that the changes have been made.
10. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs consistent with the provisions of this permit, in order to control
contaminants 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.

Footnotes:
1 Measurement Frequency: Twice per year (unless other provisions of this permit require monthly
sampling) during a measureable storm event, until either another permit is issued for this facility
or until this permit is revoked or rescinded. If the facility is monitoring monthly because of Tier Two
or Tier Three response actions under the previous General Permit, the facility shall continue a
monthly monitoring and reporting schedule in Tier Two or Tier Three status until relieved by the
provisions of this permit or the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. Where physical
separation between outfalls prevents collecting all samples within the first 30 minutes, the permittee
shall begin sampling within the first 30 minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Division's letter granting ROS shall be kept
on site with the SPPP.
4 For each sampled measureable storm event, an on -site 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.
All analytical monitoring shall be performed during a measurable storm event.
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 DEMLR Regional Office. See Definitions.
Part II Page 5 of 10 Pages

1 Maintain semi-annual monitoring during permit renewal process. If at the expiration of the general
permit, the permittee has submitted an application for renewal of coverage before the submittal
deadline, the permittee will be considered for renewed coverage. The applicant must continue semi-
annual monitoring until the renewed Certificate of Coverage is issued.
2 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.
In all cases, the permittee shall report the analytical results from the first sample with valid results
within the monitoring period. The permittee shall compare those results to the benchmark values in
Table 3 or Table 4. 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.

The benchmark values in Table 3 and Table 4 are not enforceable permit limits. An exceedance of a
stormwater benchmark value is not a permit violation; however, failure to respond to the exceedances
as outlined in this permit is a violation of permit conditions. The benchmarks are intended to reduce
polluted discharges by triggering the permittee's required response actions under Tiers One, Two, and
Three. See below the descriptions of Tiers One, Two, and Three response actions.
Tier One
If. The first valid sampling results are above a benchmark value for any parameter at any outfall;
Then: The permittee shall:
1. Conduct a stormwater management inspection within two weeks of receiving the sample results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern.
4. Implement the selected feasible actions within two months of the inspection.
S. Record each instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedance, the inspection date, the personnel conducting the inspection, the selected
feasible actions, and the date the selected feasible actions were implemented.
6. Note: Exceedances for a different parameter separately trigger the tiered response requirements.
Part II Page 7 of 10 Pages

Permit No. NCG190000
Tier Two
If. The first valid sampling results from two consecutive monitoring periods are above the benchmark values
for any specific parameter at a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters at every outfall where a
sampling result exceeded the benchmark value for two consecutive samples. Monthly (analytical and
qualitative) monitoring shall continue until three consecutive sample results are below the benchmark
values.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may exercise the option of contacting the DEMLR
Regional Office Engineer as provided below in Tier Three. The Regional Office Engineer may direct the
response actions on the part of the permittee as provided in Tier Three. The permittee will be
considered to be obligated under the Tier Three provisions.
S. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit COC renewal process.
Tier Three
If the valid sampling results required for the permit monitoring periods exceed the benchmark value for
any specific parameter at any specific outfall on four occasions, the permittee shall notify the DEMLR
Regional Office Engineer in writing within 30 days of receipt of the fourth analytical results. DEMLR
may but is not limited to:
• require the permittee to revise, increase, or decrease the monitoring and reporting frequency for
some or all parameters, including requiring sampling of additional or substitute parameters;
• rescind coverage under the General Permit, and require that the permittee apply for an individual
stormwater discharge 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;
• require the permittee implement site modifications to qualify for a No Exposure Exclusion; or
• require the permittee to continue Tier Three obligations through the permit COC renewal process.
Failure to monitor and report Der the Dermit terms may result in the Division reouirin
monthly monitorine and reportine for all Darameters for a specified time Deriod. Lack of a
discharge from an outfall for the monitoring period, or inability to collect a sample because of
adverse weather conditions during a monitoring period will not constitute failure to monitor, as
long as those conditions are reported on the monitoring period DMR and noted in the SPPP. (See
Adverse Weather in Definitions.) Similarly, sampling is not required outside of the facility's normal
operating hours.
However, if a facility is inactive for an extended period of time, the permittee must request, and
obtain, dormant site status from the DEMLR Regional Engineer in order to be excused from
sampling during the dormant period. The DEMLR letter granting dormant status must be kept with
the SPPP, and available for inspection.
Part II Page 8 of 10 Pages

Permit No. NCG190000
In the event that the Division releases the permittee from continued monthly monitoring and reporting
under Tier Two or Tier Three, DEMLR's release letter may remain in effect through subsequent
reissuance of this permit, unless the release letter provides for other conditions or duration.
The permittee must report all results from all valid discharge samples taken during each monitoring
period. However, for purposes of benchmark comparison and Tiered response actions, the permittee
shall use the analytical results from the first sample with valid results within the monitoring period.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to implement a quick and inexpensive way to evaluate the
effectiveness of the permittee's SPPP and to identify the potential for new sources of stormwater
pollution. Qualitative monitoring of stormwater discharge 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 as specified in Table 5 with
each required analytical monitoring event: whether semi-annual or more frequently as may be
subsequently required under Tier Two, Tier Three, or per the Qualitative Monitoring Response
requirements below. Inability to monitor because of adverse weather or lack of discharge during the
monitoring period must be documented in the SPPP and recorded on the Qualitative Monitoring
Report (see Adverse Weather in Definitions). Only stormwater discharge outfalls (SDOs) discharging
stormwater associated with industrial activity must be monitored (See Definitions).
In the event an atypical condition is noted at an SDOs, 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.

Footnotes:
1 Monitoring Frequency: Twice per year (unless other provisions of this permit prompt other frequency)
during a measureable storm event. See Table 2 for schedule of monitoring periods. The permittee must
continue qualitative monitoring throughout the permit renewal process.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) associated with industrial activity, regardless of representative outfall status (ROS).
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 SPPP.
Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying the potential
for 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, DEMLR
may but is not limited to:
• require that the permittee revise, increase, or decrease the 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.

of the volume of monitored discharges.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC regulations published
pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations
published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as
Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this general permit, all test procedures must
produce 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 general 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 analytical 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 (SPPP). Copies of analytical monitoring results shall also be
maintained on -site. The permittee shall retain records of all monitoring information, including

Adverse Weather
Adverse conditions are those that are dangerous or create inaccessibility for personnel, such as local
flooding, high winds, or electrical storms, or situations that otherwise make sampling impractical.
When adverse weather conditions prevent the collection of samples during the sample period, the
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.
