FACT SHEET
AUTHORIZATION TO DISCHARGE UNDER THE
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES)
GENERAL PERMIT FOR POINT SOURCE DISCHARGES TO WATERS OF THE
COMMONWEALTH OF PENNSYLVANIA FROM THE
APPLICATION OF PESTICIDES
DEP's regulations at 25 Pa. Code §92a.54 provide for the issuance of a General Permit. The Department may issue
a General Permit, in lieu of issuing individual permits, for a clearly and specifically described category of point source
discharges, if the point sources meet the following conditions:
Involve the same, or substantially similar, types of operations.
Discharge the same types of wastes.
Require the same effluent limitations or operating conditions, or both.
Require the same or similar monitoring.
Do not discharge toxic or hazardous pollutants as defined in sections 307 and 311 of the Federal Act (33
U.S.C.A. §§1317 and 1321) or any other substance that—because of its quantity; concentration; or physical,
chemical or infectious characteristics—may cause or contribute to an increase in mortality or morbidity in
either an individual or the total population, or pose a substantial present or future hazard to human health or
the environment when discharged into surface waters.
Are more appropriately controlled under a General Permit than under individual permits, in the opinion of the
Department.
Individually and cumulatively do not have the potential to cause or contribute to a violation of an applicable
water quality standard established under 25 Pa. Code Chapter 93 (relating to water quality standards) or
cause significant adverse environmental impact.
Do not discharge to a surface water classified as a High Quality Water (HQ) or an Exceptional Value Water
(EV) under 25 Pa. Code Chapter 93 (relating to water quality standards).
1. ACTIVITIES COVERED UNDER THE GENERAL PERMIT –
The General Permit is available to operators (as
defined in Attachment A of this fact sheet) who discharge to waters of the Commonwealth of Pennsylvania
(Commonwealth) from the application of (1) biological pesticides or (2) chemical pesticides that leave a residue
(collectively called Pesticides), when the pesticide application is for one of the following pesticide use patterns:
A.
Mosquito and Other Flying Insect Pest Control
to control public health/nuisance and other flying insect
pests that develop or are present during a portion of their life cycle in or above standing or flowing water.
Public health/nuisance and other flying insect pests in this use category include mosquitoes and black flies.
B.
Weed and Algae Pest Control
to control weeds, algae, and pathogens that are pests in water and at
water's edge, including ditches, canals, and/or right-of-ways.
C.
Animal Pest Control
to control animals pests in water and at water‘s edge. Animal pests in this use
category include fish, lampreys, insects, mollusks, and pathogens.
D.
Forest Canopy Pest Control
application of a pesticide to a forest canopy to control the population of a
pest species (e.g., insect or pathogen) where, to target the pests effectively, a portion of the pesticide
unavoidably will be applied over and deposited to water.

2. AUTHORIZATION TO DISCHARGE UNDER THE GENERAL PERMIT WITHOUT SUBMITTING A NOTICE OF
INTENT (NOI)
Under 40 CFR Part 122.28 (b)(2)(v), Some pesticides application operators may, at the discretion of the Director,
―be authorized to discharge under a General Permit without submitting a notice of intent (NOI) where the
Department finds that the NOI requirement would be inappropriate‖.
Operators who meet the eligibility provisions outlined on Part 1 of the Fact Sheet and whose discharges are
under the annual threshold level as identified in Table 1, are automatically authorized to discharge beginning
October 29, 2011, in compliance with the requirements of the General Permit without submission of an NOI. If
the Operator intends to use an Algaecide, Herbicide or Fish Control Chemical in waters of the Commonwealth
then joint approval from Pennsylvania Fish and Boat Commission (PFBC) and Department‘s Water Supply
Management Program must be obtained, even if the discharge(s) would be under the threshold areas in Table 1.
3. SUBMISSION OF NOI IS REQUIRED FOR COVERAGE UNDER THE GENERAL PERMIT
If you are a Decision-Maker and know or reasonably should have known that your pesticides application will
exceed Annual (i.e., calendar year) Treatment Area Thresholds listed in Table 1 for any one or more of the
pesticide use type you must submit a complete and accurate Notice of Intent (NOI) Form
(3800-PM-BPNPSM0345b) to DEP. Federal and State agencies and pest control districts must submit an NOI
regardless of the Annual Treatment Threshold Area. If the NOI is accepted, DEP will formally notify the
discharger of the coverage by transmitting a copy of the General Permit bearing an individual identification
number. Notice of each NOI approval will be published by DEP in the
Pennsylvania Bulletin
.
An NOI provides notice of a Decision-Maker‘s intent for discharges from its pesticide application activities to be
covered under the General Permit. Coverage is for the operator who filed the NOI, including its employees,
contractors, subcontractors, and other agents, for all activities identified on the NOI for the duration of the
General Permit unless coverage is terminated by submitting Notice of Termination Form
(3800-PM-BPNPSM0345e).
Operators can download the appropriate form to a personal computer, complete the form electronically and print
the document for submittal to DEP using the following steps:
Type in DEP's elibrary website address: http://www.elibrary.dep.state.pa.us/dsweb/HomePage
Select: Permit and Authorization Packages
Select: Water Management
Select: NPDES (National Pollutant Discharge Elimination System)
Select: General Permits
Select: PAG-15
If a submitted NOI is not timely, accurate, or complete, then any employee, contractor, subcontractor or other
entity that discharges without the required NOI is not covered by the General Permit.

4. DISCHARGE IS NOT COVERED BY THE GENERAL PERMIT WHEN ONE OR MORE OF THE FOLLOWING
CONDITIONS EXIST:
A.
The discharge is to waters classified as HQ or EV under 25 Pa. Code Chapter 93;
B.
Discharges are not eligible for coverage under the General Permit from a pesticide application to waters of
the Commonwealth if the water is identified as impaired by that pesticide or its degradates;
C.
The discharges are covered by another NPDES permit, or the discharges were included in a permit that
within the last five years has been or is in the process of being denied, terminated, or revoked by DEP (this
does not apply to the routine reissuance of permits every five years);
D.
The discharge contains any toxic or hazardous pollutant or any other substance which - because of its
quantity; concentration; or physical, chemical or infectious characteristics - may cause or contribute to an
increase in mortality or morbidity in either an individual or the total population, or pose a substantial present
or future hazard to human health or the environment when discharged into surface waters of the
Commonwealth;
E.
The discharge, either individually or cumulatively, has the potential to cause significant adverse
environmental impact, including those discharges which would create a public health hazard or nuisance;
F.
The discharge is not, or will not be, in compliance with any of the terms or conditions of this General Permit;
G.
The applicant has failed and continues to fail to comply or has shown a lack of ability or intention to comply
with a regulation, permit, schedule of compliance or order issued by DEP;

3800-PM-BPNPSM0345g 8/2012
Fact Sheet
- 4 -
H.
The discharge is not, or will not, result in compliance with applicable effluent limitations or water quality
standards;
I.
The discharge is determined by DEP to require an individual NPDES permit to ensure compliance with the
federal Clean Water Act, Pennsylvania‘s Clean Streams Law, or rules and regulations promulgated thereto;
or where a change has occurred in the availability of demonstrated technology or practices for the control or
abatement of pollutants applicable to the point source;
J.
The discharge is subject to a categorical point source effluent limitation;
K.
The discharge is associated with an activity that is subject to an existing NPDES individual or General
Permit, except as allowed herein; or is from a residence where an NPDES permit has been terminated or
denied;
L.
The discharge would adversely affect a state or federal listed endangered or threatened species or its critical
habitat; and
The discharge would interfere with a downstream riparian landowner's reasonable use of surface waters, property
rights, or otherwise cause a private or public nuisance.
5. REQUIRING AN INDIVIDUAL PERMIT OR ALTERNATIVE GENERAL PERMIT
DEP may amend, revoke, suspend or terminate previously issued coverage under the General Permit and
require the discharger to obtain an individual NPDES permit or an alternative NPDES General Permit in
accordance with 40 CFR §122.64 and §124.5 for any of the reasons above. In addition, any interested person
may petition DEP to take this action. If the discharge is to a water body with an approved TMDL, DEP will
require an individual permit for the discharge if DEP deems coverage under the General Permit is inconsistent
with the TMDL.
If DEP requires a discharger to obtain an individual NPDES permit, the discharger must submit a complete
NPDES application within 90 days of receipt of the notification. Failure to submit the application within 90 days
shall result in automatic termination of coverage under the General Permit. Timely submission of a complete
application shall result in continuation of coverage under the General Permit, until such time as DEP takes final
action on the pending permit application.
When an individual NPDES permit is issued for a discharge covered by the General Permit, the applicability of
the General Permit to that point source is automatically terminated on the effective date of the individual permit.
A discharger excluded from coverage under the General Permit solely because it already has an individual
permit may submit an NOI for coverage under the General Permit. If the NOI is accepted, DEP will revoke the
individual permit and notify the discharger of the facility coverage under the General Permit.
As in the case of individual NPDES permits, General Permits may be issued, amended, suspended, revoked,
reissued or terminated in accordance with Title 25 Pa. Code Chapter 92a.
6. PUBLIC NOTICE OF GENERAL PERMIT AND PUBLIC HEARING
DEP will publish a notice in the Pennsylvania Bulletin of the draft, renewed, reissued or any amendments to the
General Permit in accordance to 25 Pa. Code §92a.84, and after a comment period (normally 30 days), notice of
the final, renewed, reissued or amended General Permit will be published in the Pennsylvania Bulletin.
There will be a 30-day period following publication of notice during which written comments may be submitted by
interested persons before the Department makes its final determinations. Written comments submitted during
the 30-day comment period will be retained by the Department and considered in making the final
determinations. The period for comment may be extended at the discretion of the Department for one additional
15-day period. The Department will provide an opportunity for any interested person or group of persons, any
affected State, any affected interstate agency, the Administrator or any interested agency, to request or petition
for a public hearing with respect to the proposed general permit. The request or petition for public hearing, which
must be filed within the 30-day period allowed for filing of written comments, shall indicate the interest of the
party filing the request and the reasons why a hearing is warranted. A hearing will be held if there is a significant
public interest, including the filing of requests or petitions for the hearing.

The PAG-15 General Permit applies to eligible discharge applications of pesticides meeting the requirements of
the General Permit. Discharges to HQ or EV waters are excluded from coverage under the General Permit.
8. EFFLUENT LIMITATIONS AND COMPLIANCE WITH WATER QUALITY STANDARDS
The General Permit establishes effluent limitations in the form of continued implementation of the technology-
based and water quality based effluent limitations along with site specific control measures that minimize
discharge of pesticides to waters of the Commonwealth.
A. Technology-Based Effluent Limitations
Implementation of site-specific control measures that minimize discharges of pesticides to waters of the
Commonwealth would be required to meet the effluent limitations in this section.
1.
Applicator’s Responsibilities:
To meet the effluent limitations of this permit, all Applicators must
implement Part 8 A.1 to minimize the discharge of pesticides to waters of the Commonwealth from the
application of pesticides, through the use of Pest Management Measures as defined in Appendix A of the
General Permit.
a. To the extent not determined by the Decision-Maker, use only the amount of pesticide and frequency
of pesticide applications necessary to control the target pest, using equipment and procedures
appropriate for this task.
b. Maintain pesticide application equipment in proper operating condition including requirement to
calibrate, clean and repair such equipment and prevent leaks, spills or other unintended discharges.
c. Assess weather conditions (e.g. temperature, precipitation and wind speed) in the treatment area to
ensure the application is consistent with all applicable federal requirements.
2.
Decision-Maker’s Responsibilities: For All Decision-Makers
To meet the effluent limitations in Part 8 A.2, all Decision-Makers must minimize the discharge of
pesticides to waters of the Commonwealth from the application of pesticides, through the use of Pest
Management Measures, as defined in Appendix A of the General Permit.
To the extent the Decision-Maker determines the amount of pesticide or frequency of pesticide
application, the Decision-Maker must use only the amount of pesticide and frequency of pesticide
application necessary to control the target pest.
Decision-Maker’s Responsibilities: For Decision-Makers Required to Submit NOIs
To meet the effluent limitations of this permit, prior to pesticide application, all Decision-Makers who are
required to submit an NOI as required in Part 1 and Table 1 must also implement Pest Management
measures as detailed in Attachment B of this fact sheet to minimize the discharge of pesticides to waters
of the Commonwealth from the application of pesticides, through the use of Pesticide Management
Measures, as defined in Attachments A and B of this fact sheet.
B. Water Quality-Based Effluent Limitations
All Operators must control discharges as necessary to meet applicable numeric and narrative state water
quality standards, for any discharges authorized under this General Permit, with compliance required upon
beginning such discharges.
If at any time an Operator become aware (e.g. through self-monitoring or notification from DEP) or DEP
determines that the Operator‘s discharge causes or contributes to an excursion of applicable water quality
standards, operators must take corrective action as required in Part 12 of the Fact Sheet.
9. MONITORING, REPORTING, RECORD KEEPING AND OTHER REQUIREMENTS
A. Representative Sampling
1. Samples and measurements taken for the purpose of monitoring shall be representative of the monitored
activity.

3800-PM-BPNPSM0345g 8/2012

2. Records Retention - Operators must retain records of all monitoring information, including all calibration
and maintenance records and all original strip chart recordings for continuous monitoring
instrumentation, for a period of at least 3 years from the date the permit expires or the date the
Operator‘s authorization is terminated. This period may be extended by request of DEP at any time.
3. Recording of Results
For each measurement or sample taken pursuant to the requirements of the General Permit, the
permittee shall record the following information:
a. The exact place, date and time of sampling or measurements;
b. The person(s) who performed the sampling or measurements;
c. The date(s) the analysis was performed;
d. The person(s) who performed the analysis;
e. The analytical techniques or methods used and the associated detection level; and,
f. The results of such analysis.
B. Recordkeeping Requirements
This part applies to all Operators (Applicator and Decision-Makers); for details see Attachment D of the fact
sheet.
C. Visual Monitoring Requirements for Pesticide Applicators.
During any pesticide application with
discharges authorized under this permit, all Applicators must, when considerations for safety and feasibility
allow, visually assess the area to and around where pesticides are applied for possible and observable
adverse incidents, as defined in Attachment A, caused by application of pesticides, including the
unanticipated death or distress of non-target organisms and disruption of wildlife habitat, recreational or
municipal water use.
D. Visual Monitoring Requirements for all Operators.
During any Operator post-application surveillance of
any pesticide application with discharges authorized under this permit, all Operators must visually assess the
area to and around where pesticides were applied for possible and observable adverse incidents, as defined
in Attachment A, caused by application of pesticides, including the unanticipated death or distress of non-
target organisms and disruption of wildlife habitat, recreational or municipal water use.
E. Reporting of Monitoring Results
1. The permittee shall effectively monitor the operation and efficiency of equipment and the quantity and
quality of the discharge(s) as specified in this General Permit.
2. Annual Report: Decision-Makers who are required to submit an NOI due to overage in Annual
Treatment Area Threshold or are defined as a Large Entity in Attachment A of the fact sheet must submit
an annual report to DEP using form 3800-PM-BPNPSM0345f. Once the Decision-Maker meets the
obligation to submit an annual report, the Decision-Maker must submit an annual report each calendar
year thereafter for the duration of coverage under the General Permit, whether or not the Decision-Maker
has discharges from the application of pesticides in any subsequent calendar year. Decision-Makers
can submit the annual report electronically using DEP‘s eDMR (electronic Discharge Monitoring Report)
system. Decision-Makers must submit the annual report to DEP no later than January 28 of the following
year (and retain a copy for records) for all pesticide activities covered under this General Permit
occurring during the previous calendar year. Annual reporting requirements begin with those discharges
occurring during calendar year 2012.
The annual report (3800-PM-BPNPSM0345f) must include information for the calendar year, with the first
annual report required to include activities for the portion of the calendar year after the effective date of
the NOI. If the effective date is after December 1, the Decision-Makers are not required to submit an
annual report for that first partial year but must submit annual reports thereafter, with the first annual
report submitted also including information from the first partial year.
When the Decision-Makers terminate permit coverage, an annual report must be submitted for the
portion of the year up through the date of termination. The annual report is due no later than 45 days
after your termination date.

5. Upset
a.
Effect of an upset. An upset constitutes an affirmative defense to an action brought for non-
compliance with technology-based permit effluent limitations if the requirements of Part A III.E.3
are met. No determination made during administrative review of claims that non-compliance was
caused by upset, and before an action for non-compliance, is final administrative action subject to
judicial review. See 40 CFR §122.41(n)(2).
b.
Conditions necessary for a demonstration of upset. See 40 CFR §122.41(n)(3). An operator who
wishes to establish the affirmative defense of upset must demonstrate, through properly signed,
contemporaneous operating logs, or other relevant evidence that:
i. An upset occurred and that you can identify the cause(s) of the upset;
ii. The permitted activity was at the time being properly operated; and
iii. The permittee provided notice of the upset as required in Part A III.E.3.
iv. The permittee complied with any remedial measures required under Part B I.G.
c. Burden of proof. In any enforcement proceeding, the permittee, as the one seeking to establish the
occurrence of an upset, has the burden of proof. See 40 CFR §122.41(n)(4).The permittee shall
report all instances of non-compliance not reported under paragraph G.4.b. of this section, at the
time of annual reporting. The reports shall contain the information in paragraph G.4. of this section.
6. Other Non-Compliance
The permittee shall report all instances of non-compliance not reported under paragraph G.5 of this
section, at the time of annual reporting. The reports shall contain the information listed in paragraph G.4
of this section.
10. RENEWAL OF COVERAGE
The General Permit will expire 5 years from the date of its issuance. DEP will publish a notice in the
Pennsylvania Bulletin of the draft, renewed, or reissued General Permit or of any amendments to this General
Permit, and after a comment period notice of the final, renewed, reissued or amended General Permit will be
published in the Pennsylvania Bulletin. Any person with an unexpired approval of coverage under the General
Permit shall be responsible for complying with the final renewed, reissued or amended General Permit. Such
persons will be covered by the General Permit even if the discharger has not submitted a separate notice of
intent to be covered by such final, renewed, reissued or amended General Permit. Such person may request
coverage under an individual permit. See 40 CFR §122.28(b)(vi); 25 Pa. Code §92a.54(c) and (d).

ATTACHMENT A
DEFINITIONS
Action Threshold
– the point at which pest populations or environmental conditions cannot be tolerated necessitating
that pest control action be taken based on economic, human health, aesthetic, or other effects. An action threshold
may be based on current and/or past environmental factors that are or have been demonstrated to be conducive to
pest emergence and/or growth, as well as past and/or current pest presence. Action thresholds are those conditions
that indicate both the need for control actions and the proper timing of such actions.
Active Ingredient
– any substance (or group of structurally similar substances if specified by the permitting authority)
that will prevent, destroy, repel or mitigate any pest, or that functions as a plant regulator, desiccant, or defoliant
within the meaning of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) Sec. 2(a). Active ingredient
also means a pesticidal substance that is intended to be produced and used in a living plant, or in the produce
thereof, and the genetic material necessary for the production of such a pesticidal substance. 40 CFR §152.3 and 40
CFR §174.3
Adverse Incident
– means an unusual or unexpected incident that an Operator has observed upon inspection or of
which the Operator otherwise become aware, in which
:
(1) There is evidence that a person or non-target organism has likely been exposed to a pesticide residue, and
(2) The person or non-target organism suffered a toxic or adverse effect.
The phrase ―toxic or adverse effect‖ includes effects that occur within waters of the Commonwealth on non-target
plants, fish or wildlife that are unusual or unexpected (e.g., effects are to organisms not otherwise described on the
pesticide product label or otherwise not expected to be present) as a result of exposure to a pesticide residue, and
may include:
Distressed or dead juvenile and small fishes;
Washed up or floating fish;
Fish swimming abnormally or erratically;
Fish lying lethargically at water surface or in shallow water;
Fish that are listless or nonresponsive to disturbance;
Stunting, wilting, or desiccation of non-target submerged or emergent aquatic plants; and
Other dead or visibly distressed non-target aquatic organisms (amphibians, turtles, invertebrates, etc.)
The phrase ―toxic or adverse effect‖ also includes any adverse effects to humans (e.g., skin rashes) or domesticated
animals that occur either directly or indirectly from a direct contact with or a secondary effect from a discharge (e.g.,
sickness from consumption of plants or animals containing pesticides) to waters of the Commonwealth that are
temporally and spatially related to exposure to a pesticide residue (e.g., vomiting, lethargy).
Annual Treatment Area Threshold
– an area (in acres) or linear distance (in miles) in a calendar year to which a
Decision-Maker is authorizing and/or performing pesticide applications in that area for activities covered under this
permit.
For calculating annual treatment areas for Mosquitoes and Other Flying Insect Pest Control and Forest Canopy Pest
for comparing with any threshold in Table 1, count each pesticide application activity to a treatment area (i.e., that
area where a pesticide application is intended to provide pesticidal benefits within the pest management area) as a
separate area treated. For example, applying pesticides three times a year to the same 3,000 acre site should be
counted as 9,000 acres of treatment area for purposes of determining if such an application exceeds an Annual
Treatment Area Threshold. The treatment area for these two pesticide use patterns is additive over the calendar
year.
For calculating annual treatment areas for Weed and Algae Control and Animal Pest Control for comparing with any
threshold in Table 1, calculations should include either the linear extent of or the surface area of waters for
applications made to waters of the Commonwealth or at water‘s edge adjacent to waters of the Commonwealth. For
calculating the annual treatment area, count each treatment area only once, regardless of the number of pesticide
application activities performed on that area in a given year. Also, for linear features (e.g., a canal or ditch), use the
length of the linear feature whether treating in or adjacent to the feature, regardless of the number of applications
made to that feature during the calendar year. For example, whether treating the bank on one side of a ten-mile long

ditch, banks on both sides of the ditch, and/or water in that ditch, the total treatment area is ten miles for purposes of
determining if an NOI is required to be submitted. Additionally, if the same 10 mile area is treated more than once in
a calendar year, the total area treated is still 10 miles for purposes of comparing with any threshold in Table 1. The
treatment area for these two pesticide use patterns is not additive over the calendar year.

facility, and nearest hazardous chemical responder must be in locations that are readily accessible and
available.
E. Signature Requirements.
Decision-Maker must sign, date and certify the PDMP in accordance with Part B II.B
the General Permit. This requirement is consistent with standard NPDES permit conditions described in 40 CFR
122.22 and is intended to ensure that the operator understands his/her responsibility to create and maintain a
complete and accurate PDMP. The signature requirement includes an acknowledgment that there are significant
penalties for submitting false information.
F. Documentation to Support Eligibility Considerations under Other Federal Laws
[reserved]
G. Pesticide Discharge Management Plan Modifications.
A Decision-Maker required to submit an NOI and is a
Large Entity must modify the PDMP whenever necessary to address any of the triggering conditions for
corrective action in Part A I.D of the General Permit or when a change in pest control activities significantly
changes the type or quantity of pollutants discharged. Changes to the PDMP must be made before the next
pesticide application that results in a discharge, if practicable, or if not, no later than 90 days after any change in
pesticides application activities. The revised PDMP must be signed and dated in accordance with
Part 1 E
of this
section.
H. Pesticide Discharge Management Plan Availability.
A Decision-Maker required to submit an NOI and is a
Large Entity must retain a copy of the current PDMP, along with all supporting maps and documents, at the
address provided in Section II of the NOI. The PDMP and all supporting documents must be readily available,
upon request, and copies of any of these documents provided, upon request, to DEP. DEP may provide copies
of the PDMP or other information related to this General Permit that is in its possession to members of the public.

ATTACHMENT E
CORRECTIVE ACTION DOCUMENTATION AND REPORTING
1. Corrective Action –
All Operators must comply with the provisions in this attachment for any discharges
authorized under this General Permit, with compliance required upon beginning such discharges.
A.
Situations requiring revision of Control Measures. If any of the following situations occur, Operators must
review and, as necessary, revise the evaluation and selection of Pest Management Measures to ensure that
the situation is eliminated and will not be repeated in the future:
a. An unauthorized release or discharge associated with the application of pesticides (e.g., spill, leak, or
discharge not authorized by this or another NPDES permit) occurs;
b. Operators become aware, or DEP concludes, that Pest Management Measures are not adequate or
sufficient for the discharge to meet applicable water quality standards;
c. Any monitoring activities indicate failure to meet applicable technology-based effluent limitations of this
General Permit that Operators failed to implement;
d. An inspection or evaluation of your activities by DEP reveals that modifications to the Pest Management
Measures are necessary to meet the effluent limitations in the General Permit; and
e. An Operator observes, or is otherwise made aware of an adverse incident, as defined in Part A II of the
General Permit.
B.
Corrective Action Deadlines. If an Operator determines that changes to Pest Management Measures are
necessary to eliminate any situation identified in Part 1 A of this attachment, such changes must be made
before the next pesticide application that results in a discharge if practicable, or if not, as soon as possible
thereafter.
C.
Effect of Corrective Action. The occurrence of a situation identified in Part 1 A of this attachment may
constitute a violation of the permit. Correcting the situation according to Part 1 A of this attachment does not
absolve Operators of liability for any original violation. However, failure to comply with Part 1 B of this
attachment constitutes an additional permit violation. DEP will consider the appropriateness and promptness
of corrective action in determining enforcement responses to permit violations.
DEP may impose additional requirements and schedules of compliance, including requirements to submit
additional information concerning the condition(s) triggering corrective action or schedules and requirements
more stringent than specified in this permit. Those requirements and schedules will supersede those of Part
1 A and Part 1 B of the attachment if such requirements conflict.
2. Adverse Incident
A.
Twenty-Four (24)-Hour Adverse Incident Notification. Adverse Incident Notification Required.
a. Except as provided for in Part 2 E of this attachment, if an Operator observes or is otherwise made
aware of an adverse incident, as defined in Part A II of the General Permit (also Attachment A of the
Fact Sheet), which may have resulted from a discharge from a pesticide application, the Operator must
immediately notify the appropriate EPA Incident Reporting Contact, as identified at
www.epa.gov/npdes/pesticides. This notification must be made by telephone within 24 hours of the
Operator becoming aware of the adverse incident and must include at least the following information:
1. The caller‘s name and telephone number;
