AUTHORIZATION TO DISCHARGE UNDER THE PESTICIDES GENERAL PERMIT (PGP)
This General Permit authorizes an Operator of a point source discharge of pollutants (discharge) associated with the
application of pesticides to discharge in accordance with the requirements of this General Permit.
Coverage under this General Permit applies to any Operator that meets the eligibility requirements identified in
Paragraph I below and if so required, submits a Notice of Intent (NOI) in accordance with the Annual Treatment Area
Thresholds in Table 1. An Operator, defined in Part A II, is the entity associated with the application of pesticides
that results in a discharge to waters of the Commonwealth of Pennsylvania (Commonwealth) and that meets either of
the following two criteria: (1) An entity who performs the application of a pesticide or who has day-to-day control of
the application (i.e., authorized to direct workers to carry out those activities); or (2) an entity with control over the
decision to perform pesticide applications, including the ability to modify those decisions, which results in a discharge
to waters of the Commonwealth and are necessary to ensure compliance with the permit. Operators identified by
criterion (1) above are referred in this permit as Applicators, while Operators identified by criterion (2) above are
referred to in this permit as Decision-Makers. As defined, more than one Operator may be responsible for complying
with this General Permit for any single discharge from the application of pesticides.
For the purpose of this General Permit, all Operators are defined as either an Applicator or a Decision-Maker or both
an Applicator and a Decision-Maker.
DEP may deny coverage under this General Permit and require submittal of an application for an individual NPDES
permit based on a review of the NOI or other information.
I. ELIGIBLE PESTICIDES USE PATTERNS
This General Permit is available to Operators who discharge to waters of the 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:
1.
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.
2.
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 (ROWs).
3.
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.
4.
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.
II. NOI REQUIREMENTS
To obtain authorization under this General Permit, an Operator must meet the eligibility requirements identified in
Paragraph I and submit a complete and accurate Notice of Intent (NOI).
Operators meeting the eligibility provisions outlined in Paragraph I and whose discharges are not subject to the
requirement to submit an NOI, as outlined in Paragraph III, are automatically authorized to discharge beginning
October 29, 2011, in compliance with the requirements of this General Permit without the submission of an NOI.
However, if applications are below the thresholds listed in Table 1, Operators intending to use an Algicide,
Herbicide or Fish Control Chemical in waters of the Commonwealth must still obtain joint approval from
Pennsylvania Fish and Boat Commission (PFBC) and DEP under 25 Pa. Code § 91.38(2).

An NOI provides notice of an Operators‟ intent for discharges from its pesticide application activities to be
covered under this General Permit. Coverage is for the applicant who filed the NOI, including its employees,
contractors, subcontractors, and other agents, for all activities identified on the NOI for the duration of this
General Permit unless coverage is terminated pursuant to Part B III.F. If an NOI is not submitted in a timely,
accurate, or complete manner, then any employee, contractor, subcontractor or other entity that discharges
without the required NOI is not covered by this permit.
III. OPERATORS WHO ARE REQUIRED TO SUBMIT A NOTICE OF INTENT (NOI)
Decision-Makers intending to perform pest control activities that will result in a discharge and know or reasonably
should have known that those activities will exceed one or more of the Annual (i.e., calendar year) Treatment
Area Thresholds listed in Table 1 below, as defined in Part A II, are required to submit an NOI to obtain coverage
under this General Permit for discharges to waters of the Commonwealth resulting from the application of
pesticides. Federal and state agencies and pest control districts must submit an NOI regardless of the Annual

IX. 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 affected by an approved TMDL, DEP will
require an individual permit for the discharge if DEP determines that coverage under this General Permit will not
be consistent with the TMDL. DEP may require any discharger authorized to discharge under this General
Permit to apply for an individual NPDES permit, but only if the owner or operator has been notified in writing that
an individual permit application is required. This notice shall include the following:
1. a brief statement of the reasons for this decision;
2. an application form;
3. a statement setting a deadline for the person to file the application; and
4. a statement that on the effective date of the individual NPDES permit, coverage under this General Permit
shall automatically terminate.
The applicant shall submit the individual permit application within 90 days of receipt of the notice. DEP may
grant additional time to submit the application for an individual permit upon written request from the applicant. If
the person fails to submit a permit application within the time allowed, coverage under this General Permit is
automatically terminated at the end of the day specified for individual permit application submittal.

X. TERMINATION OF COVERAGE
Operators covered under this General Permit that are not required to submit an NOI are terminated from permit
coverage when they no longer have a discharge from the application of pesticides or their discharges are
covered under an NPDES individual permit or alternative NPDES General Permit.
A Decision-Maker who is required to submit an NOI as identified in Paragraph III must submit a complete and
accurate Notice of Termination (3800-PM-BPNPSM0345e). Authorization to discharge under this General Permit
terminates immediately upon issuance of a termination letter by DEP, after receipt of the complete Notice of
Termination. A Notice of Termination may not be valid without meeting one or more of the conditions identified in
Part C of the Notice of Termination. You are responsible for complying with the terms of this permit until the
authorization is terminated by the DEP. If a Decision-Maker who is required to submit an NOI ever met the
Annual Treatment Area Threshold for having to submit Annual Reports pursuant to Part A III.F, the Decision-
Maker who is required to submit an NOI must file an Annual Report for the portion of the year up through the
date of the termination. The Annual Report is due no later than 45 days after your termination date.
XI. THE AUTHORITY GRANTED BY THIS GENERAL PERMIT IS SUBJECT TO THE FOLLOWING
CONDITIONS:
1. Any applicant authorized to discharge under this General Permit may request to be excluded from coverage
by applying for an individual permit. That applicant shall submit an approved Pennsylvania individual
NPDES application form, with reasons supporting the request to DEP. The request shall be granted by
issuance of an individual permit if the reasons cited by the applicant are adequate to support the request.
2. When an individual NPDES permit is issued to an applicant otherwise authorized to discharge under this
General Permit, the applicability of this General Permit is automatically terminated on the effective date of
the individual permit. When an individual NPDES permit is denied to an applicant authorized to discharge
under this General Permit, the applicant can continue discharging if all eligibility requirements under this
General Permit are met. If the applicant does not meet the eligibility requirements of this General Permit, or
is otherwise prohibited from this General Permit coverage, coverage under this General Permit is
automatically terminated on the date of such denial, unless otherwise specified by DEP.
3. An application for renewal of coverage under this General Permit must be submitted to DEP at least
180 days prior to the expiration date of coverage indicated on the approval for coverage form (unless
permission has been granted by DEP for submission at a later date). A request for renewal of coverage is to
be made using the latest PAG-15 Notice of Intent (NOI) form.
In the event that a timely and complete application for renewal has been submitted and DEP is unable,
through no fault of the permittee, to reissue the permit or approval for coverage before its current coverage
expiration date, the terms and conditions of the approved coverage will automatically continue and will
remain fully effective and enforceable pending the issuance or denial of the renewal of permit coverage,
provided the permittee is, and has been, operating in compliance with the terms and conditions of the
previously issued General Permit.
4. Issuance, reissuance, or amendments of the General Permit - Unless extended by DEP by reissuance, this
General Permit will expire 5 years from the date of its final issuance and availability. DEP will publish a
notice in the
Pennsylvania Bulletin
of the draft, renewed, reissued or 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
.
5. Coverage under this General Permit shall be revoked by DEP if monitoring data indicates that toxic
pollutant(s) are, or are expected to be, discharged in toxic amounts. If there is evidence indicating potential
or actual adverse impacts on water quality due to the discharge, the permittee may be required to obtain an
individual NPDES permit.
6. No condition of this General Permit shall release the permittee from any responsibility or requirement under
any other Federal or Pennsylvania environmental statute or regulation or any local ordinances.

PART A
EFFLUENT LIMITATIONS, DEFINITIONS, MONITORING, RECORDKEEPING AND REPORTING
REQUIREMENTS
I. EFFLUENT LIMITATIONS
This General Permit establishes technology-based and water quality-based effluent limitations along with site
specific control measures that minimize discharge of pesticides to waters of the Commonwealth of Pennsylvania.
A. Technology-Based Effluent Limitations
To meet the effluent limitations in this section, All Operators with discharge(s) authorized under this General
Permit must implement site-specific control measures that minimize the discharges of pesticides to waters of
the Commonwealth. The term “minimize” is defined in Part A II.
1. Applicator’s Responsibilities-
To meet the effluent limitations of this permit, all Applicators must
implement the requirements in a. through c. below to minimize the discharge of pesticides to waters of
the Commonwealth from the application of pesticides, through the use of Pest Management Measures
(see Appendix A), as defined in Part A II of this General Permit.
a. 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 required calibration,
cleaning, and repair of equipment. In addition, caution must be used to prevent leaks, spills or other
unintended discharges.
c. Assess weather conditions (i.e., temperature, precipitation and wind speed) in the treatment area to
ensure the application is consistent with all applicable federal requirements.
2. Decision-Makers Responsibilities: For all Decision-Makers
All Decision-Makers must minimize the discharge of pesticides into the waters of the Commonwealth
from the application of pesticides, through the use of Pest Management Measures (see Appendix A), as
defined in Part A II of this 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.
3. 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 Table 1 must also implement Pest Management options as
detailed in Appendix A 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 Part A II and
Appendix A.
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
commencing such discharges.
If at any time an Operator becomes aware (i.e., 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 (see Appendix C).

II. 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.

Permit Number:
Permit
- 11 -
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.
Applicator – any entity who performs the application of a pesticide or who has day-to-day control of the
application (i.e., authorized to direct workers to carry out those activities) that results in a discharge to waters of
the Commonwealth.
Best Management Practices (BMPs) –
control measures that may be implemented to meet effluent limitations.
These include schedules of activities, prohibitions of practices, maintenance procedures, and other
management practices to minimize the discharge of pollutants to waters of the Commonwealth. BMPs also
include treatment requirements, operating procedures, and practices to control spillage or leaks, waste disposal,
or drainage from raw material storage. (40 CFR 122.2)
Biological Control Agents –
organisms that can be introduced to Operator sites, such as herbivores, predators,
parasites, and hyperparasites (see US FWS IPM Guidance, 2004).
Biological Pesticides (also called biopesticides) -
include microbial pesticides, biochemical pesticides and plant-
incorporated protectants (PIP). Microbial pesticide means a microbial agent intended for preventing, destroying,
repelling, or mitigating any pest, or intended for use as a plant regulator, defoliant, or desiccant, that (1) is a
eukaryotic microorganism including, but not limited to, protozoa, algae, and fungi; (2) is a prokaryotic
microorganism, including, but not limited to, Eubacteria and Archaebacteria; or (3) is a parasitically replicating
microscopic element, including but not limited to, viruses (40 CFR 158.2100(b)). Biochemical pesticide means a

– any practice used to meet the effluent limitations that comply with manufacturer
specifications, industry standards and recommended industry practices related to the application of pesticides,
relevant legal requirements and other provisions that a prudent Operator would implement to reduce and/or
eliminate pesticide discharges to waters of the Commonwealth.
Pesticide –
means (1) any substance or mixture of substances intended for preventing, destroying, repelling, or
mitigating any pest, (2) any substance or mixture of substances intended for use as a plant regulator, defoliant,
or desiccant, and (3) any nitrogen stabilizer, except that the term „„pesticide‟‟ shall not include any article that is
a “new animal drug” within the meaning of section 201(w) of the Federal Food, Drug, and Cosmetic Act
(21 U.S.C. 321(w)), that has been determined by the U.S. Secretary of Health and Human Services not to be a
new animal drug by a regulation establishing conditions of use for the article, or that is an animal feed within the
meaning of section 201(x) of such Act (21 U.S.C. 321(x)) bearing or containing a new animal drug. The term
“pesticide” does not include liquid chemical sterilant products (including any sterilant or subordinate disinfectant
claims on such products) for use on a critical or semi-critical device, as defined in section 201 of the Federal
Food, Drug, and Cosmetic Act (21 U.S.C. 321). For purposes of the preceding sentence, the term “critical
device” includes any device that introduced directly into the human body, either into or in contact with the

used to control pests. The definition encompasses all uses of pesticides authorized under FIFRA including uses

3800-PM-BPNPSM0345d 9/2012
Permit Number:
Permit
- 14 -
authorized under sections 3 (registration), 5 (experimental use permits), 18 (emergency exemptions), 24(c)
(special local needs registrations), and 25(b) (exemptions from FIFRA).
Note: drugs used to control diseases of humans or animals (such as livestock and pets) are not considered
pesticides; such drugs are regulated by the Food and Drug Administration. Fertilizers, nutrients, and other
substances used to promote plant survival and health are not considered plant growth regulators and thus are
not pesticides. Biological control agents, except for certain microorganisms, are exempted from regulation
under FIFRA. (Biological control agents include beneficial predators such as birds or ladybugs that eat insect
pests, parasitic wasps, fish, etc).
This permit uses the term “pesticide” when referring to the “pesticide, as applied.” When referring to the
chemical in the pesticide product with pesticidal qualities, the permit uses the term “active ingredient.”
Pesticide Product –
a pesticide in the particular form (including composition, packaging, and labeling) in which
the pesticide is, or is intended to be, distributed or sold. The term includes any physical apparatus used to
deliver or apply the pesticide if distributed or sold with the pesticide.
Pesticide Research and Development –
Activities undertaken on a systematic basis to gain new knowledge
(research) and/or the application of research findings or other scientific knowledge for the creation of new or
significantly improved products or processes (experimental development).
Pesticide Residue –
includes that portion of a pesticide application that is discharged from a point source to
waters of the Commonwealth and no longer provides pesticidal benefits. It also includes any degradates of the
pesticide.
Point source –
any discernible, confined, and discrete conveyance, including but not limited to any pipe, ditch,
channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation,
landfill leachate collection system, vessel, or other floating craft from which pollutants are or may be discharged.
This term does not include return flows from irrigated agriculture or agricultural stormwater runoff.
(40 CFR 122.2)
Pollutant –
dredged spoil, solid waste, incinerator residue, filter backwash, sewage, garbage, sewage sludge,
munitions, chemical wastes, biological materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt,
and industrial, municipal, and agricultural waste discharged into water. For purposes of this definition, a
“biological pesticide” is considered a “biological material,” and any “pesticide residue” resulting from use of a
“chemical pesticide” is considered a “chemical waste.” (40 CFR 122.2)
Small Entity –
any (1) public entity that serves a population of 10,000 or less or (2) private enterprise that does
not exceed the Small Business Administration size standard as identified at 13 CFR 121.201.
Target Pest –
the organism(s) toward which pest management measures are being directed.
Total Maximum Daily Load (TMDL)
– the maximum amount of a pollutant that a water body can receive and still
meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL includes
wasteload allocations (WLAs) for point source discharges; load allocations (LAs) for nonpoint sources and/or
natural background, and must include a margin of safety (MOS) and account for seasonal variations. (Section
303(d) of the CWA and 40 CFR 130.2 and 130.7)
Treatment Area –
The “treatment area” includes the entire area, whether over land or water, where the pesticide
application is intended to provide pesticidal benefits within the pest management area. In some instances, the
treatment area will be larger than the area where pesticides are actually applied. For example, the treatment
area for a stationary drip treatment into a canal includes the entire width and length of the canal over which the
pesticide is intended to control weeds. Similarly, the treatment area for a lake or marine area is the water
surface area where the application is intended to provide pesticidal benefits.
Toxic Pollutant –
means those pollutants, or combinations of pollutants, including disease-causing agents,
which after discharge and upon exposure, ingestion, inhalation or assimilation into any organism, either directly
from the environment or indirectly by ingestion through food chains, may, on the basis of information available to

DEP cause death, disease, behavioral abnormalities, cancer, genetic mutations, physiological malfunctions,
including malfunctions in reproduction, or physical deformations in these organisms or their offspring.
(25 Pa. Code 92a.1)
Upset –
means an exceptional incident in which there is unintentional and temporary noncompliance with
technology based permit effluent limitations because of factors beyond your reasonable control. An upset does
not include non-compliance to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.
(40 CFR 122.41(n)(1))
Waters of the Commonwealth –

courses, storm sewers, lakes, dammed water, ponds, springs and all other bodies or channels of conveyance of
surface water, or parts thereof, including wetlands, whether natural or artificial, within or on the boundaries of
this Commonwealth.
Water Quality Impaired –
See „Impaired Waters‟.
Water Quality Standards –
water quality goals for a water body, or portion thereof, established by designating
the use or uses to be made of the water and by setting criteria necessary to protect the uses. Water quality
standards also include an anti-degradation policy and implementation procedures. States, Territories, Tribes
and EPA adopt water quality standards to protect public health or welfare, enhance the quality of water and
serve the purposes of the Clean Water Act (See CWA sections 101(a) and 303(c)).
Wetlands -
means those areas that are inundated or saturated by surface or groundwater at a frequency and
duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation
typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and
similar areas. (40 CFR 122.2)
III. SELF-MONITORING, REPORTING AND RECORDS KEEPING
A. Monitoring Requirements for Pesticide Applicators.
Operators must monitor the amount of pesticide
applied to ensure that the lowest amount to effectively control the pest is used, consistent with reducing the
potential for development of pest resistance. Operators must also monitor pesticide application activities to
ensure regular maintenance activities are performed and to ensure that application equipment is in proper
operating condition to reduce the potential for leaks, spills, or other unintended discharge of pesticides to
waters of the Commonwealth. Additionally, Operators must monitor pesticide application activities to ensure
that the application equipment is in proper operating condition by adhering to any manufacturer‟s
recommendations and industry practices, and by calibrating, cleaning, and repairing equipment on a regular
basis.
B. Visual Monitoring Requirements for all Operators.
All operators covered under this General Permit must
conduct spot checks in the area to and around where pesticides are applied for possible and observable
adverse incidents, as defined in Part A II, caused by application of pesticides, including but not limited to the
unanticipated death or distress of non-target organisms and disruption of wildlife habitat, recreational or
municipal water use. Visual assessments of the application site must be performed:
1. During any post-application surveillance or efficacy check that you conduct, if surveillance or an efficacy
check is conducted.
2. During any pesticide application, when considerations for safety and feasibility allow.
C. Representative Sampling
1. Visual Monitoring shall be representative of the monitored activity.
2. Records Retention - All records of monitoring activities and results (including all original strip chart
recordings for continuous monitoring instrumentation and calibration and maintenance records), copies
of all reports required by this General Permit, and records of all data used to complete the application
(Notice of Intent) for this General Permit shall be retained by the permittee for 3 years from the date of
the visual monitoring, report or application. The 3-year period shall be extended as requested by DEP.

APPENDIX C
CORRECTIVE ACTION DOCUMENTATION AND REPORTING
1.
Corrective Action –
All Operators must comply with the provisions in this appendix 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.
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 appendix, 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 appendix may
constitute a violation of the permit. Correcting the situation according to Part 1 A of this appendix does not
absolve Operators of liability for any original violation. However, failure to comply with Part 1 B of this
appendix 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 appendix 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 appendix, if an Operator observes or is otherwise made aware
of an adverse incident, as defined in Part A II of the General Permit, 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;

3800-PM-BPNPSM0345d 9/2012

24-hour notice;
5. How and when the Operator became aware of the adverse incident;
6. Description of the location of the adverse incident;
7. Description of the adverse incident identified and the pesticide product, including EPA pesticide
registration number, for each product applied in the area of the adverse incident;
8. Description of any steps the Operator has taken or will take to correct, repair, remedy, clean up, or
otherwise address any adverse effects; and
9. If known, the identity of any other Operators authorized for coverage under this permit for discharges
from the pesticide application activities that resulted in the adverse incident.
b. If an Operator is unable to notify DEP within 24 hours, the Operator must do so as soon as possible and
also provide an appropriate rationale for why the Operator was unable to provide such notification within
24 hours. DEP‟s contact information for reporting adverse incidents can be found by visiting DEP‟s
website
(
www.dep.state.pa.us
) and clicking on “Report an Incident”.
c. The adverse incident notification and reporting requirements are in addition to what the registrant is
required to submit under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) section 6(a)(2)
and its implementing regulations at 40 CFR Part 159.
B. Adverse Incident Notification Not Required
Reporting of adverse incidents is not required under this permit in the following situations:
a. An Operator is aware of facts that indicate that the adverse incident was not related to toxic effects or
exposure from the pesticide application;

APPENDIX D
PESTICIDES DISCHARGE MANAGEMENT PLAN (PDMP)
A Pesticides Discharge Management Plan (PDMP) applies to any Decision-Maker who is required to submit an NOI,
and is a Large Entity, as defined in Part A II of the General Permit. Except for any application made in response to a
declared pest emergency situation, as defined in Part A II, a Decision-Maker who is required to submit an NOI, and is
a Large Entity, must prepare a PDMP and submit it with the NOI
.
Some sections of the Pesticide Discharge
Management Plan (PDMP) will require input from the pesticide applicator.
The PDMP documents how Decision-Makers will implement the Technology based and water quality based effluent
limitations of the General Permit, including the evaluation and selection of Pest Management Measures to meet
those effluent limitations in order to minimize discharges. In the PDMP, Decision-Makers may incorporate by
reference any procedures or plans in other documents that meet the requirements of this permit. If Decision-Makers
rely upon other documents to comply with the effluent limitations in this permit, such as a preexisting pest
management plan, the Decision-Maker must attach to the PDMP a copy of any portions of any documents that are
used to document the implementation of the effluent limitations.
1. Contents of the Pesticide Discharge Management Plan
The PDMP must include the following elements:
a. Pesticide Discharge Management Team
b. Problem Identification
c. Pest Management Options Evaluation
d. Response Procedures
i.
Spill Response Procedures
ii.
Adverse Incident Response Procedures
e. Documentation to support eligibility considerations under other state and federal laws
f. Signature Requirements.
A. PDMP Team.
Decision-Maker must identify all the persons (by name and contact information) that compose
the team as well as each person‟s individual responsibilities, including:
1. Person(s) responsible for managing pests in relation to the pest management area
2. Person(s) responsible for developing and revising the PDMP; and
3. Person(s) responsible for developing, revising, and implementing corrective actions and other effluent
limitation requirements.
B. Problem Identification.
Decision-Makers must document the following:

a. Pest problem description. Document a description of the pest problem at the pest management
area, including identification of the target pest(s), source(s) of the pest problem, and source of data
used to identify the problem in Parts 1, 2, 3, and 4 of Pest Management Measures (Appendix A);
b. Action Threshold(s). Describe the action threshold(s) for the pest management area, including data
used in developing the action threshold(s) and method(s) to determine when the action threshold(s)
has been met;
c. General location map. In the plan, include a general location map (e.g., USGS quadrangle map, a
portion of a city or county map, or other map) that identifies the geographic boundaries of the area to
which the plan applies and location of the waters of the Commonwealth; and
d. Water quality standards. Document any Special Protection water (High Quality and Exceptional
Value Waters) and any water(s) identified as impaired by a substance which either is an active
ingredient or a degradate of such an active ingredient.
C. Pest Management Options Evaluation
Decision-Makers must document the evaluation of the pest management options, including combination of
the pest management options, to control the target pest(s). Pest management options include the following:
No action, prevention, mechanical/physical methods, cultural methods, biological control agents, and
pesticides. In the evaluation, Decision-Makers must consider the impact to water quality, impact to non-
target organisms, feasibility, cost effectiveness, and any relevant previous Pest Management Measures.
D. Response Procedures.
Decision-Makers must document the following procedures in the PDMP:
a. Spill Response Procedures – At a minimum Decision-Maker must have:
i. Procedures for expeditiously stopping, containing, and cleaning up leaks, spills, and other
releases. Employees who may cause, detect, or respond to a spill or leak must be trained in
these procedures and have necessary spill response equipment available. If possible, one of
these individuals should be a member of your PDMP team.
ii. Procedures for notification of appropriate facility personnel, emergency response agencies, and
regulatory agencies.
b. Adverse Incident Response Procedures – At a minimum Decision-Makers must have:
i. Procedures for responding to any adverse incident resulting from pesticide applications;
ii. Procedures for notification of the adverse incident, both internal to Decision-Makers
agency/organization and external. Contact information for state/federal permitting agency,
nearest emergency medical 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
