1.0 Coverage under This Permit 

This permit covers any Operator who meets the eligibility requirements identified in Part 

1.1 and if so required, has submitted a Notice of Intent (NOI) in accordance with Part 1.2. 

For the purpose of this permit, “Operator” is defined in Appendix A to mean any entity 

associated with the application of pesticides which results in a discharge to Waters of the 

United States that meets either of the following two criteria: (1) any entity who performs 

the application of a pesticide or who has day-to-day control of the application (i.e., they 

are authorized to direct workers to carry out those activities); or (2) any entity with 

control over the decision to perform pesticide applications including the ability to modify 

those decisions. Operators identified in (1) above are referred to in this permit as 

Applicators while Operators identified in (2) are referred to in this permit as Decisionmakers. As defined, more than one Operator may be responsible for complying with this 

permit for any single discharge from the application of pesticides.

For purposes of this permit, all Operators are defined as either an Applicator or a 

Decision-maker or both an Applicator and a Decision-maker.

When an Operator is both an Applicator and a Decision-maker, the Operator must 

comply with all applicable requirements imposed on both Applicators and Decisionmakers. When the permit references all “Operators,” both Applicators and Decisionmakers must comply. 

1.1 Eligibility

1.1.1 Activities Covered

This permit is available to Operators who discharge to Waters of the United States 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 and/or canals.

c. Animal Pest Control—to control animal 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.
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

1-2 

1.1.2 Limitations on Coverage

1.1.2.1 Discharges to Water Quality Impaired Waters 

Operators are not eligible for coverage under this permit for any discharges from a 

pesticide application to Waters of the United States if the water is identified as impaired 

by a substance which either is an active ingredient in that pesticide or is a degradate of 

such an active ingredient. For purposes of this permit, impaired waters are those that 

have been identified by a state, tribe, or EPA pursuant to section 303(d) of the CWA as 

not meeting applicable state or tribal water quality standards. Impaired waters, for the 

purposes of this permit, consist of both waters with EPA-approved or EPA-established 

total maximum daily loads (TMDLs) and waters for which EPA has not yet approved or 

established a TMDL. A list of those waters is available at www.epa.gov/OWOW/tmdl/. 

If a discharge from a pesticide application would not be eligible under this permit 

because the water is listed as impaired for that specific pesticide, but there is evidence 

that shows the water is no longer impaired, Operators may submit this information to 

EPA consistent with Table 1-2 in Part 1.2.3, and request that coverage be allowed under 

this permit.

1.1.2.2 Discharges to Waters Designated as Tier 3 for Antidegradation Purposes 

Except for discharges from pesticide applications made to restore or maintain water 

quality or to protect public health or the environment that either do not degrade water 

quality or only degrade water quality on a short-term or temporary basis, Operators are 

not eligible for coverage under this permit for discharges to Waters of the United States if 

the water is designated by a state or tribe as Tier 3 (Outstanding National Resource 

Waters) for antidegradation purposes under Title 40 of the Code of Federal Regulations

(CFR) 131.12(a)(3). A list of Tier 3 waters in geographic areas covered under this permit 

is available on EPA’s website at www.epa.gov/npdes/pesticides. 

1.1.2.3 Discharges Currently or Previously Covered by another Permit

Discharges are not eligible for coverage under this permit if any of the following 

circumstances apply:

a. The discharge is covered by another NPDES permit, or 

b. The discharge was included in a permit that in the past 5 years has been or is in the 

process of being denied, terminated, or revoked by EPA (this does not apply to the 

routine reissuance of permits every 5 years). 

1.1.2.4 Endangered and Threatened Species and Critical Habitat Protection 

Coverage under this permit is available only for discharges and discharge-related activities 

that are not likely to adversely affect species that are federally-listed as endangered or 

threatened ("listed") under the Endangered Species Act (ESA) or habitat that is federallydesignated as critical under the ESA ("critical habitat"), except as provided in Criterion B, C, 

and, for 60 days, D, below. As one of the provision in this permit that help limit adverse 

effects to these resources, the six criteria (A-F) below relate to the impacts a prospective 

discharger's activities may have on a subset of these listed species and critical habitat. 

Specifically, the conditions below relate to potential impacts on NMFS Listed Resource of 

Concern, as defined in Appendix A. These are resources that have been identified through 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

1-3 

consultation with NMFS as having potential vulnerability that warrants the additional 

protections entailed in compliance with A-F. Other provisions that protect listed species 

more broadly include Section 1.6, which requires compliance with any conditions resulting 

from an ESA Section 7 consultation or ESA Section 10 permit, and the waiting period 

between NOI submittal and authorization to discharge, which provides an opportunity for 

NMFS and the U.S. Fish and Wildlife Service, EPA, and members of the public to identify 

any potential impacts on listed species and for EPA to notify the permittee if further 

conditions or an individual permit are necessary.

A step-by-step guide for determining eligibility with these conditions relating to the 

protection of NMFS Listed Resources of Concern, as defined in Appendix A, is provided in 

Appendix I of the permit. To demonstrate eligibility, Decision-makers must meet one or 

more of the following six criteria (A-F) for the entire term of coverage under the permit: 

Criterion A. Pesticide application activities will not result in a point source discharge to 

one or more Waters of the United States containing National Marine Fisheries Service 

(NMFS) Listed Resources of Concern, as defined in Appendix A, for this permit. 

Criterion B. Pesticide application activities for which permit coverage is being requested 

will discharge to one or more receiving Waters of the United States containing NMFS Listed 

Resources of Concern, as defined in Appendix A, but consultation with NMFS under section 

7 of the ESA has been concluded for pesticide application activities covered under this 

permit. Consultations can be either formal or informal, and would have occurred only as a 

result of a separate federal action. The consultation addressed the effects of pesticide 

discharges and discharge-related activities on federally-listed threatened or endangered 

species and federally-designated critical habitat, and must have resulted in either:

i. A biological opinion from NMFS finding no jeopardy to federally-listed species and no 

destruction/adverse modification of federally-designated critical habitat; or

ii. Written concurrence from NMFS with a finding that the pesticide discharges and 

discharge-related activities are not likely to adversely affect federally-listed species or 

federally-designated critical habitat.

Criterion C. Pesticide application activities for which permit coverage is being requested 

will discharge to one or more Waters of the United States containing NMFS Listed 

Resources of Concern, as defined in Appendix A, but all “take” of these resources associated 

with such pesticide application activities has been authorized through NMFS’ issuance of a 

permit under section 10 of the ESA, and such authorization addresses the effects of the 

pesticide discharges and discharge-related activities on federally-listed species and federallydesignated critical habitat. (The term "take" means to harass, harm, pursue, hunt, shoot, 

wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct. See 

Section 3 of the Endangered Species Act, 16 U.S.C. § 1532(19).) 

Criterion D. Pesticide application activities were, or will be, discharged to one or more 

Waters of the United States containing NMFS Listed Resources of Concern, as defined in 

Appendix A, but only in response to a Declared Pest Emergency Situation. Decision-makers 

must provide EPA with their rationale supporting the determination whether the discharge is 

likely to adversely affect NMFS Listed Resources of Concern, including the description of 

appropriate measures to be undertaken to avoid or eliminate the likelihood of adverse effects. 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

1-4 

Criterion E. Pesticide application activities for which permit coverage is being requested 

in the NOI will discharge to one or more Waters of the United States containing NMFS 

Listed Resources of Concern, as defined in Appendix A. Eligible discharges include those 

where the Decision-maker includes in the NOI written correspondence from NMFS that 

pesticide application activities performed consistent with appropriate measures will avoid or 

eliminate the likelihood of adverse effects to Listed Resources of Concern. Eligibility under 

this criterion is contingent upon the Decision-maker following the measures described in 

correspondence from NMFS designed to avoid or eliminate the likelihood of adverse effects. 

Criterion F. Pesticide application activities for which permit coverage is being requested 

in the NOI will discharge to one or more Waters of the United States containing NMFS 

Listed Resources of Concern, as defined in Appendix A. Eligible discharges include those 

from pesticide application activities that are demonstrated by the Decision-maker as not 

likely to adversely affect NMFS Listed Resources of Concern or that the pest poses a greater 

threat to the NMFS Listed Resources of Concern than does the discharge of the pesticide. 

Decision-makers must provide EPA with their documentation demonstrating the basis for 

their finding. 

1.2 Authorization to Discharge under This Permit

1.2.1 How to Obtain Authorization

The following discharges, consistent with the permit eligibility provisions in Part 1.1, are 

automatically authorized by this permit beginning October 31, 2011. 

- Eligible discharges made prior to the NOI submission deadline. See Table 1-2 

in Part 1.2.3; 

- Eligible discharges that result from the application of a pesticide as part of 

pesticide research and development, as defined in Appendix A; 

- Eligible discharges for which submission of an NOI is not required. See Parts 

1.2.2 and 1.2.3. 

To obtain authorization under this permit for all other eligible discharges, a Decisionmaker must submit a timely, complete, and accurate NOI consistent with the 

requirements of Parts 1.2.2 and 1.2.3. 

1.2.2 Decision-makers Required to Submit an NOI

Any “Decision-maker who is or will be required to submit an NOI” as defined in 

Appendix A, is identified in Table 1-1. 

For calculating annual treatment area totals for purposes of determining if an NOI must 

be submitted, see the definition for “annual treatment area threshold” in Appendix A of 

the permit.

An NOI provides notice to EPA that a Decision-maker intends to discharge to Waters of 

the United States from pesticide application activities eligible for coverage under this 

permit. Information required is provided on the NOI form included in Appendix D. The 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

1-5 

NOI must identify the pest management area where the Decision-maker will conduct 

activities resulting in discharges to Waters of the United States to be covered under this 

permit. If the activities will result in discharges to any Tier 3 water, eligible under Part 

1.1.2.2, the NOI must specifically identify the Tier 3 water by the name listed at 

www.epa.gov/npdes/pesticides. 

If required to submit an NOI, a Decision-maker must submit the NOI once, in accordance 

with the deadlines in Part 1.2.3, Table 1-2. The Decision-maker must submit an updated 

NOI if the criteria in Part 1.2.3, Table 1-3 are met. The Decision-maker must prepare and 

submit the NOI using EPA’s electronic Notice of Intent system (eNOI) available on 

EPA’s website (www.epa.gov/npdes/pesticides/eNOI) unless eNOI is otherwise 

unavailable or the Decision-maker has obtained a waiver from the requirement to use 

eNOI for submission of the NOI. Decision-makers waived from the requirement to use 

eNOI for NOI submission must certify on the paper NOI submitted to EPA that use of 

eNOI will incur undue burden or expense compared to using the paper Notice of Intent 

form and then provide a basis for this determination. EPA will immediately post on that 

website all NOIs received. Late NOIs will be accepted, but authorization to discharge 

will not be retroactive.

Coverage will be available for the duration of the permit for Decision-makers who file an 

NOI, including the Decision-makers’ employees, contractors, subcontractors, and other 

agents, for all activities identified on the NOI unless coverage is terminated pursuant to 

Parts 1.2.5 or 1.3. If a submitted NOI is not timely, accurate, or complete, any employee, 

contractor, subcontractor or other entity that discharges without the required NOI is not 

covered by this permit. 

Applicators who are not also Decision-makers do not need to submit an NOI. 

1.2.3 Discharge Authorization Date

Except for discharges identified in Tables 1-1 through 1-3, any Operator with eligible 

discharges is automatically authorized to discharge under this permit without submission 

of an NOI. Decision-makers with eligible discharges identified in Tables 1-1 through 1-3 

are authorized under this permit consistent with the requirements in those tables. 

On the basis of a review of an NOI or other information, EPA may delay authorization to 

discharge beyond any timeframe identified in Table 1-2, determine that additional 

technology-based and/or water quality-based effluent limitations or other conditions are 

necessary, or deny coverage under this permit and require submission of an application 

for an individual NPDES permit, as detailed in Part 1.3. 

All Operators with eligible discharges are authorized for permit coverage through 

January 12, 2012 without submission of an NOI. After January 12, 2012, all Operators 

with eligible discharges for which an NOI is not required also are automatically covered 

under this permit. After January 12, 2012, all Decision-makers with eligible discharges 

for which an NOI is required are required to submit an NOI consistent with the earliest 

applicable due date identified in Table 1-2. Decision-makers may submit multiple NOIs 

with different activities on each of those NOIs such that discharges from different 

activities are authorized at different times.
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

1-6 

Decision-makers who are required to submit an NOI, but are discharging between 

October 31, 2011 and January 12, 2012, must begin complying with Part 2.2 

requirements as of October 31. 2011.

2 On the basis of a review of an NOI or other information, EPA may delay authorization to discharge beyond any timeframe 

identified in Table 1-2, determine that additional technology-based and/or water quality-based effluent limitations or other 

conditions are necessary, or deny coverage under this permit and require submission of an application for an individual NPDES 

permit, as detailed in Part 1.3.

3 Within 30 days after EPA posts on the Internet receipt of a complete and accurate NOI, for those areas with NMFS Listed 

Resources of Concern, as defined in Appendix A, NMFS will provide EPA with a determination as to whether it believes the 

eligibility criterion of “not likely to adversely affect listed species or designated critical habitat” has been met, could be met with 

conditions that NMFS identifies, or has not been met. EPA expects to rely on NMFS’s determination in deciding whether to 

withhold authorization. If NMFS does not provide EPA with this information within 30 days of EPA posting on the Internet receipt 

of a complete and accurate NOI, the discharges will be authorized 30 days after EPA posts on the Internet receipt of a complete 

NOI. 

4 In any Declared Pest Emergency Situation in areas with Waters of the United States containing NMFS Listed Resources of 

Concern, NMFS will have 30 days after submission of an NOI to provide EPA with a determination as to whether it believes the 

eligibility criteria of “not likely to adversely affect listed species or designated critical habitat” has been met, could be met with 

conditions that NMFS identifies, or has not been met. EPA expects to rely on NMFS’s determination in deciding whether to 

disallow continued permit coverage or if additional conditions are necessary. If NMFS does not provide EPA with a 

recommendation within 30 days of EPA posting on the Internet receipt of a complete and accurate NOI, authorization for these 

discharges will continue. If EPA identifies additional permit conditions or prohibitions, or includes additional permit conditions or 

prohibitions recommended by NMFS, as necessary to qualify discharges for particular Operators as eligible for coverage beyond 

60 days under the PGP, those conditions remain in effect for the life of the permit.

5 EPA may authorize certain discharges in less than 30 days, but no fewer than 10 days, for any discharges authorized under 

Criterion B, C, or E of Part 1.1.2.4 (for which NMFS has already evaluated the effects of these discharges).

1.2.4 Continuation of This Permit

If this permit is not reissued or replaced before the expiration date, it will be 

administratively continued in accordance with 40 CFR 122.6 and remain in force and 

effect. If an Operator was authorized to discharge under this permit before the expiration 

date, any discharges authorized under this permit will automatically remain covered by 

this permit until the earliest of the following:

a. A Decision-maker is authorized for coverage under a reissued permit or a 

replacement of this permit, following the timely and appropriate submittal of a 

complete NOI requesting authorization to discharge under the new permit and in 

compliance with the requirements of the NOI;

b. A Decision-maker submits a Notice of Termination and that notice is processed and 

posted on the Internet consistent with Part 1.2.5.1; 

c. An NPDES individual permit for a discharge resulting from application of a pesticide 

that would otherwise be covered under this permit is issued or denied; 

d. EPA issues a formal permit decision not to reissue this general permit, at which time 

EPA will identify a reasonable period for covered dischargers to seek coverage under 

an alternative NPDES general permit or an NPDES individual permit. Coverage 

under this permit will cease when coverage under another permit is 

granted/authorized; or 

e. EPA has informed the Operator that its discharge is no longer covered under this 

permit.

1.2.5 Terminating Coverage

1.2.5.1 Submitting a Notice of Termination. To terminate permit coverage, a Decision-maker 

who is required to submit an NOI as identified in Part 1.2.2, must submit a complete and 

accurate Notice of Termination. Information required to be included in a Notice of 

Termination is provided in Appendix E. Decision-makers required to submit a Notice of 

Termination must prepare and submit that information using EPA’s electronic eNOI 

system (www.epa.gov/npdes/eNOI) unless eNOI is otherwise unavailable or EPA waives 

the electronic submission requirement for an Operator consistent with the requirements 

identified on the Notice of Termination form in Appendix E. The authorization to 

discharge under this permit terminates at 11:59 p.m. of the day that a complete Notice of 

Termination is processed and posted on EPA’s website (www.epa.gov/npdes). If a 

Decision-maker submits a Notice of Termination without meeting one or more of the 

conditions identified in Part 1.2.5.2, the Notice of Termination is not valid. Decisionmakers are responsible for complying with the terms of this permit until authorization is 

terminated. If required to submit annual reports pursuant to Part 7 prior to the termination 

of authorization under this permit, Decision-makers must file an annual report for the 

portion of the year up through the date of termination. The annual report is due no later 

than February 15 of the following year.

1.2.5.2 When to Submit a Notice of Termination. A Decision-maker who is required to submit 

an NOI as identified in Part 1.2.2 must submit a Notice of Termination within 30 days 

after one or more of the following conditions have been met: 

a. A new Decision-maker has taken over responsibility of the pest control activities 

covered under an existing NOI;

b. The Decision-maker has ceased all discharges from the application of pesticides for 

which permit coverage was obtained and does not expect to discharge during the 

remainder of the permit term for any of the use patterns as identified in Part 1.1.1; or 

c. The Decision-maker has obtained coverage under an NPDES individual permit or an 

alternative NPDES general permit for all discharges required to be covered by an 

NPDES permit, unless coverage was obtained consistent with Part 1.3, in which case 

coverage under this permit will terminate automatically.

1.2.5.3 Termination for Operators not Required to Submit an NOI. Operators covered under 

this permit, who are not required to submit an NOI, are terminated from permit coverage 

when there is no longer a discharge from the application of pesticides or the discharges 

are covered under an NPDES individual permit or alternative NPDES general permit.

1.3 Alternative Permits

1.3.1 Requirements for Coverage under an Alternative Permit

In accordance with 40 CFR 122.64 and 124.5, EPA may require Operators to apply for 

and/or obtain authorization to discharge under either an NPDES individual permit or an 

alternative NPDES general permit.

If EPA requires an Operator to apply for an NPDES individual permit, EPA will notify 

the Operator in writing that a permit application is required. Such a notification will 

include a brief statement of the reasons for the decision and will provide application 

information. In addition, for Operators whose discharges are authorized under this 

permit, any notice will set a deadline to file the permit application and will include a 

statement that on the effective date of the NPDES individual permit, coverage under this 

general permit will terminate. EPA may grant additional time to submit the application if 

an Operator submits a request setting forth reasonable grounds for additional time. If 

covered under this permit and the Operator fails to submit an NPDES individual permit 

application as required by EPA, the applicability of this permit to such Operator is 

terminated at the end of the day specified by EPA as the deadline for application 

submittal. EPA may take enforcement action for any unpermitted discharge or violation 

of any permit requirement.

1.3.2 Operator Requesting Coverage under an Alternative Permit

If an Operator does not want to be covered by this general permit but needs permit 

coverage, the Operator can apply for an NPDES individual permit. In such a case, the 

Operator must submit an individual permit application in accordance with the 

requirements of 40 CFR 122.26(c)(1)(ii), with reasons supporting the request, to EPA at 

the applicable EPA Regional Office listed in Part 8 of this permit. The request may be 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

1-11 

granted by issuance of an NPDES individual permit or authorization of coverage under 

an alternative NPDES general permit.

When an individual NPDES permit is issued, or the Operator is authorized under an 

alternative NPDES general permit to discharge a pollutant to Waters of the United States 

as a result of a pesticide application, authorization to discharge under this permit is 

terminated on the effective date of the NPDES individual permit or the date of 

authorization of coverage under the alternative NPDES general permit.

1.4 Severability

Invalidation of a portion of this permit does not render the whole permit invalid. EPA’s 

intent is that the permit will remain in effect to the extent possible; if any part of this 

permit is invalidated, the remaining parts of the permit will remain in effect unless EPA 

issues a written statement otherwise.

1.5 Other Federal and State Laws

Operators must comply with all other applicable federal and state laws and regulations 

that pertain to the application of pesticides. For example, this permit does not negate the 

requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and 

its implementing regulations to use registered pesticides consistent with the product’s 

labeling. In fact, applications in violation of certain FIFRA requirements could also be a 

violation of the permit and therefore a violation of the CWA (e.g. exceeding label 

application rates). Additionally, other laws and regulations might apply to certain 

activities that are also covered under this permit (e.g., United States Coast Guard 

regulations). 

1.6 Federally Listed Endangered and Threatened Species and 

Designated Critical Habitat

Operators must comply with all conditions and/or requirements that address discharges 

from activities also covered under this permit resulting from any of the following preexisting situations:

a. ESA Section 7 consultation that Operators have completed with FWS and/or NMFS, 

and/or 

b. ESA Section 10 permit issued to the Operator by FWS and/or NMFS.

2.0 Technology-Based Effluent Limitations

This Part includes technology-based effluent limitations applicable to all Operators, as 

defined in Appendix A, for any discharges authorized under this permit, with compliance 

required upon beginning such discharge. All Operators are classified as either 

“Applicators” or “Decision-makers,” as defined in Appendix A, or both. Applicators 

must perform the tasks identified in Part 2.1 – Applicators’ Responsibilities. Decisionmakers must perform the tasks identified in Part 2.2 – Decision-makers’ Responsibilities. 

There may be instances when a single entity acts as both an Applicator and a Decisionmaker.

If an Operator’s discharge of pollutants results from the application of pesticide that is 

being used solely for the purpose of “pesticide research and development,” as defined in 

Appendix A, the Operator must use such pesticide consistent with any applicable 

research plan and experimental use permit.

As stated in Part 1.5, this permit requires all Operators to comply with all other 

applicable federal or state laws and regulations that pertain to application of pesticides by 

the Operator.

2.1 Applicators’ Responsibilities – To meet the effluent limitations of this permit, 

all Applicators must implement Part 2.1 to minimize the discharge of pesticides to Waters 

of the United States from the application of pesticides, through the use of Pest 

Management Measures, as defined in Appendix A.

2.1.1 To the extent not determined by the Decision-maker, use only the amount of pesticide 

and frequency of pesticide application necessary to control the target pest, using 

equipment and application procedures appropriate for this task. 

2.1.2 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. 

2.1.3 Assess weather conditions (e.g. temperature, precipitation and wind speed) in the 

treatment area to ensure application is consistent with all applicable federal requirements.

2.2 Decision-makers’ Responsibilities: For All Decision-makers

To meet the effluent limitations in Part 2.2, all Decision-makers must minimize the 

discharge of pesticides to Waters of the United States from the application of pesticides, 

through the use of Pest Management Measures, as defined in Appendix A. 

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 Any Decision-maker Who 

is or Will be Required to Submit an NOI

To meet the effluent limitations of this permit, prior to pesticide application, any

Decision-maker is or will be required to submit an NOI as required in Part 1.2.2, except

PDMP:

a. Spill Response Procedures – At a minimum, Decision-makers must have:

1. Procedures for expeditiously stopping, containing, and cleaning up leaks, spills, 

and other releases to Waters of the United States. 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 the PDMP team.

2. 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:

1. Procedures for responding to any adverse incident resulting from pesticide 

applications;

with regard to Part 1.1.2.4 (Endangered and Threatened Species and Critical Habitat 

Protection).

5.1.6 Signature Requirements. Decision-makers must sign, date and certify the PDMP in 

accordance with Appendix B, Subsection B.11. 

5.2 Pesticide Discharge Management Plan Modifications. Decisionmakers must modify the PDMP whenever necessary to address any of the triggering 

conditions for corrective action in Part 6.1, 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 pesticide application 

activities. The revised PDMP must be signed and dated in accordance with Appendix B, 

Subsection B.11. 

5.3 Pesticide Discharge Management Plan Availability. Decision-makers 

must retain a copy of the current PDMP, along with all supporting maps and documents, 

at the address provided in Section III.3 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 EPA; a State, Tribal, or local agency governing discharges or 

pesticide applications within their respective jurisdictions; and representatives of the 

United States Fish and Wildlife Service (FWS) or NMFS. EPA may provide copies of 

the PDMP or other information related to this permit that is in its possession to members 

of the public. Any Confidential Business Information (CBI), as defined in 40 CFR Part 2, 

may be withheld from the public provided that a claim of confidentiality is properly 

asserted and documented in accordance with 40 CFR Part 2; however, CBI must be 

submitted to EPA, if requested, and may not be withheld from those staff within EPA, 

FWS, and NMFS cleared for CBI review.

6.0 Corrective Action

All Operators must comply with the provisions of Part 6 for any discharges authorized under this 

permit, with compliance required upon beginning such discharge. 

6.1 Situations Requiring Revision of Pest Management Measures

Operators must review and, as necessary, revise the evaluation and selection of Pest 

Management Measures consistent with Part 2.1 and 2.2 for the following situations:

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 EPA concludes, that Pest Management Measures are not 

adequate/sufficient for the discharge to meet applicable water quality standards.

c. Any monitoring activities indicate failure to meet applicable technology-based 

effluent limitations in Part 2.

d. An inspection or evaluation of activities by an EPA official, or local, state, or tribal 

entity, reveals that modifications to the Pest Management Measures are necessary to 

meet the effluent limitations in this permit.

e. Any Operator observes or is otherwise made aware of an adverse incident as defined 

in Appendix A. 

6.2 Corrective Action Deadlines

If an Operator determines that changes to Pest Management Measures are necessary to 

eliminate any situation identified in Part 6.1, such changes must be made before or, if not 

practicable, as soon as possible after the next pesticide application that results in a 

discharge.

6.3 Effect of Corrective Action

The occurrence of a situation identified in Part 6.1 may constitute a violation of the 

permit. Correcting any situation identified in Part 6.1 does not absolve Operators of 

liability for any original violation. However, failure to comply with Part 6.2 constitutes 

an additional permit violation. EPA will consider the appropriateness and promptness of 

corrective action in determining enforcement responses to permit violations. 

EPA 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 6.1 and 6.2 if 

such requirements conflict.

fish kill or other negative aquatic impact.

b.) pH and alkalinity: The pH of the pond or lake water must be 

maintained within a pH range of 6.0 - 7.5 to minimize potential 

aluminum solubility and toxicity. If the pond has an ambient pH 

outside this range the applicant should adjust the treatment as needed 

to attain the pH range, and if the final pH after treatment is still not 

within the range then water samples from treated and untreated areas 

should be sampled and analyzed for total aluminum and dissolved 

aluminum with detection limits of 10 ppb or less.

c.) Reporting: Any observations of dead, dying or stressed fish (e.g. fish 

swimming at the surface) or wildlife deemed to be caused by the 

approved treatment shall be reported as quickly as possible to the MA 

Department of Environmental Protection and the Massachusetts 

Division of Fisheries & Wildlife. Any pH reading outside the target 

range of 6.0 - 7.5 should be further investigated and reported to the 

MA Department of Environmental Protection. All required water 

quality monitoring data, fish and wildlife observations and a narrative 

description of the treatment, including any on-site modifications to the 

application plan to maintain pH within the desired range shall be

i. Limitations on Coverage 

Discharges to Water Quality Impaired Waters. You are not eligible for 

coverage under this permit for any discharges from a pesticide application to 

waters of the Warm Springs Reservation if the water is identified as impaired 

by that pesticide or its degradates. For purposes of this permit, impaired 

waters are those that have been identified by EPA pursuant to Section 303(d) 

of the CWA or by the Warm Springs Tribe as not meeting applicable Tribal 

water quality standards. Impaired waters for the purposes of this certification 

include both waters with EPA-approved or EPA-established Total Maximum 

Daily Loads (TMDLs) and waters for which EPA has not yet approved or 

established a TMDL.

Discharges to Waters Designated as Tier 3 for Antidegradation Purposes. 

Certification for discharges from a pesticide application to waters designated 

by the Warm Springs Tribes or EPA as Tier 3 (Outstanding National Resource 

Waters) for anti-degradation purposes under 40 CFR 131.12(a)(3) and Tribal 

Ordinances 80 and 81 is not contemplated in this document. 

ii. Authorization to Discharge Under the PGP Permit

To obtain authorization under this permit, an operator must: 

A. Meet the eligibility requirements identified in EPA PGP and

B. Meet any Tribal restrictions required by Warm Springs Tribal Ordinance 

74, 80 and 81. 

If you are an operator identified in PGP Part 1.2.2, submit a complete and 

accurate Notice of Intent (NOI) to EPA and the Warm Springs Tribe. 

If you apply pesticides that result in a discharge and know or reasonably 

should have known that those activities will exceed one or more of the 

pesticide application annual (i.e., calendar year) treatment area thresholds 

listed in Table 9-4 below for the “treatment area,” as defined in PGP 

Appendix A.

1 Calculations should include the area of the applications made to: (1) waters of the Warm Springs Reservation and 

(2) conveyances with a hydrologic surface connection to waters of the Warm Springs Reservation. At the time of pesticide 

application. For calculating annual treatment area totals, count each pesticide application activity as a separate activity. For 

example, applying pesticides twice a year to a ten acre site should be counted as twenty acres of treatment area.

2 Calculations should include the linear extent of the application made at water’s edge adjacent to: (1) waters of the Warm Springs 

Reservation and (2) conveyances with a hydrologic surface connection to waters of the Warm Springs Reservation at the time of

pesticide application. For calculating annual treatment totals, count each pesticide application activity and each side of a linear water 

body as a separate activity or area. For example, treating both sides of a ten mile ditch is equal to twenty miles of water treatment area.

iii. Discharge Authorization Date

Beginning October 31, 2011, you must be covered under an NPDES permit 

for discharges to waters of the United States and specifically to the waters of 

the Warm Springs Reservation as a result of the application of a pesticide.

v. Aquatic Plant and Algae Management 

A. This section applies to products applied to the eradication of noxious and 

WSDA quarantine list weeds and the control nuisance and noxious weeds 

in lakes, rivers, streams, other standing and flowing waterbodies (not 

including irrigation canals), emergent vegetation around waterbodies, and 

roadside and ditch banks. This does not cover activities in saltwater areas. 

 B. Weed Eradication

 Eradication projects target only state-listed noxious weeds or plants listed 

 on the WSDA quarantine-list. The goal is the complete and permanent 

 removal of these species from the entire water body. As such, littoral zone 

 limitations do not apply to eradication of noxious weeds or weeds on the 

 quarantine list. Impacts to non-target plants are acceptable to the extent 

 needed to eradicate the target plants. Eradication is allowed only for:

1. All noxious weeds as identified in chapter 16-750 WAC.

2. Plants listed on the quarantine list as identified in chapter 16-752 

WAC.

3. Non-native and potentially invasive plants not listed on the above 

lists, as determined by the WSNWCB, WSDA, or Ecology. 

 C. Nuisance and Noxious Weed Control

 The goal is to maintain native aquatic vegetation for habitat while 

 allowing partial plant removal for recreation and other beneficial uses. 

 Permit requirements differ depending on plant growth forms and the legal 

 status of the plant species in Washington. Minimal impact to non-target 

 plants is acceptable to the extent needed to control the target plants.

 Nuisance plants are native plants that grow in such quantity that they 

 restrict the beneficial uses of a waterbody as defined in chapter 173-201A 

 WAC.

1. Aquatic noxious weed control 

The Permittee may apply herbicides to: 

a. 100 percent of noxious weeds if they are Class A weeds, Class B 

weeds in areas where they are designated for control, as 

identified in chapter 16-750 WAC, and Class C weeds where 

they are selected for control by a county Noxious Weed Control 

Board (RCW 17.10.080). 

b. 100 percent of any submersed noxious or quarantine-list weeds

E. Additional Restrictions

1. Identified Wetlands

The Permittee may only treat high use areas to provide for safe 

recreation and boating in identified and/or emergent wetlands. Treated 

area must be limited to protect native vegetation. For eradication 

projects, the Permittee must make every effort to protect native 

wetland vegetation while removing noxious species. 

 2. Permittee must use Washington Department of Natural Resources

(WDNR) Natural Heritage Program database to determine if sensitive, 

threatened, or endangered (rare) plants are present in the proposed 

treatment area. If a rare plant does occur in or around the waterbody, 

the Permittee must survey for the rare plant and mitigate for impacts to 

it. The rare plant database is currently located at 

http://www1.dnr.wa.gov/nhp/refdesk/plants.html. 

3. The Application of Products 

a. The Permittee must comply with the specific 

restrictions/limitations on the use of each chemical listed in 

Tables 9.7 – 9.9 below. 

b. When there are potable water restrictions on the product label, 

the Permittee must not apply any chemical until it has notified

people who withdraw drinking water from the water body. If 

requested by the affected water user(s), the Permittee must 

provide an alternative drinking water supply until the intake 

water tests at or below the concentration specified for that 

chemical in Table 9.7, or until the period specified in Table 9.7 

for that chemical has elapsed. If there is no drinking water 

restriction listed in Table 9.7, the Permittee must follow all 

label conditions for potable water supply. If requested by a 

water user, the Permittee must provide advance notice of 

pending treatments on a time schedule agreed to by all parties. 

c. If the treatment affects potable water use on water bodies with 

municipal or community drinking water intakes, the Permittee

must obtain written consent to the treatment from the 

municipality or community. The Permittee must keep this 

consent letter for 5 years.
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

9-40 

d. People withdrawing water under a legal water right or claim for 

irrigation or livestock watering purposes may request an 

alternate water supply during the treatment if the label has 

restrictions for those uses. The Permittee must provide an 

alternative water supply until the intake water tests at or below 

the irrigation restriction concentration or livestock drinking 

water concentration on the product label or until the time 

interval specified on the label has elapsed. If requested by a 

water user, the Permittee must provide advance notice of 

pending treatments on a time schedule agreed to by all parties. 

e. The Permittee must follow EDFW’s Fish and Wildlfe Treatment 

Windows for Ecology’s Aquatic Plant and Algae Management 

Permit (Treatment Windows) to protect salmon, steelhead, and bull 

trout populations and other sensitive species and habitats. WDFW 

may periodically update the Treatment Windows as new 

information becomes available see:

http://www.ecy.wa.gov/programs/wq/pesticides/final_pesticide_pe

rmits/aquatic_plants/permitdocs/wdfwtiming.pdf. If a waterbody is 

not listed in the Treatment Windows, the default window is July 15 

– October 31, both dates inclusive. Contact the regional WDFW 

biologist to develop a new timing window if the default window 

will not provide for adequate treatment.

f. The Permittee must follow the specific restrictions and advisories 

identified in Tables 9.7-9.9 below. Recreational 

restrictions/advisories apply to swimming, boating, water skiing, 

etc. Swimming restrictions/advisories apply to primary contact 

activities such as swimming, wading, and water skiing. Drinking 

water restrictions apply to residents drinking lake water as their 

sole source of potable water or where they hold a water right for 

potable water.

F. Monitoring Requirements 

1. Application of Herbicides and Algaecides 

a. The Permittee must monitor dissolved oxygen levels pre- and posttreatment when contact herbicides are used in water bodies on the 

303(d)-list for dissolved oxygen. Immediately before treating, the 

Permittee must monitor surface and bottom dissolved oxygen 

concentrations at a sampling location in the center and at the edge 

of the proposed treatment area(s).

b. The Permittee must select at least one representative treatment area 

to monitor each time the water body is treated. The Permittee must 

monitor post-treatment surface and bottom dissolved oxygen 

concentrations no earlier than seven days and no later than 14 days 

after the treatment, at the same time of day that the pre-treatment 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

9-41 

monitoring occurred and at the same sites and depths. The 

Permittee must keep the data for 5 years and make it available 

upon request. 

2. Application of Phosphorus Inactivation Products 

a. Aluminum sulfate or sodium aluminate (alum)

For whole or partial lake treatments, the Permittee must measure, 

at a minimum, surface water pH once in the morning prior to any 

alum addition and once in the afternoon one hour after alum 

addition has stopped for that day. The Permittee must continue this 

monitoring regime for the duration of the treatment and for 24 

hours following treatment completion. The monitoring location 

must be representative of water body-wide conditions. If the pH 

decreases to less than 6.2, the Permittee must stop treatment, 

analyze for alkalinity, and must take immediate steps to increase 

the pH. 

b. Calcium hydroxide/oxide or calcium carbonate treatment 

The Permittee must measure pH once on the day before treatment, 

and once in the morning and once in the afternoon for the duration 

of the treatment and for 24 hours following treatment. If the pH is 

above 9.0 due to the effects of the treatment (rather than through 

photosynthesis), the Permittee must stop treatment.

c. Continuous Injection Systems 

The Permittee must measure pH at a minimum once every two 

weeks during the first month of continuous injection and thereafter 

once a month for the duration of the injection process. The 

Permittee must ensure that pH measurements represent water 

body-wide conditions, unless the injection system is in an isolated 

area in relation to the main water body (e.g., in a bay with a narrow 

channel to the main water body). For isolated areas of water 

bodies, the Permittee must measure pH at the end of the bay and in 

the main water body.

3. The premittee must keep all monitoring records for a period of 5 years 

and make them available upon request. 

4. In some situations, the permittee prevents treated water from reaching 

some points of compliance by closing side canals/spillways. (For 

example, a permittee closes a gate to a spillway while treating the 

primary canal and all the treated water passes the closed gate.) The 

permittee shall conduct full monitoring (Condition vii.C under Section 

9.10.6 of this permit) at the points of compliance corresponding to the 

closed canals/spillways when the canals/spillways are reopened unless 

the closed canal/spillway is kept closed for double the travel time it 

takes the treated water to reach the point of closure. In this situation, 

no monitoring is required. For this special situation only, the travel 

time is counted from when the pesticide application ends. (For 

example, if a treatment ends at 1:00 and it takes four hours to pass the 

closed gate at 5:00, the permittee shall keep the gate closed for another

viii. Fish Management 

A. Allowed Active Ingredients 

1. Rotenone 

2. Antimycin-A 

3. (Potassium Permanganate (KMnO4) is the only chemical permitted to 

neutralize rotenone treated waters when necessary to prevent damage 

to non-targeted organisms and maintain water quality outside of the 

area intended for rotenone treatment.

B. Additional Restrictions

1. In order to prevent unnecessary damage to the environment, the 

permittee shall follow the best management practices defined below on 

the day of application. 

Powdered rotenone formulations shall be applied in such a way that 

minimizes airborne dust, using the best available technology such as 

the method outlined in “Utah’s Procedure for Mixing Powdered 

Rotenone into a Slurry” (Thompson et al. 2001). 

In order to prevent an exceedance of water quality standards outside 

the area intended for rehabilitation, rotenone treatment should only 

take place in lakes that are not discharging to downstream waters. This 

is accomplished by limiting treatments to lakes with closed basins or 

conducting treatments only during periods of low water, usually 

September or October.

In instances where treated waters may potentially discharge to 

downstream waters resulting in an exceedance of water quality 

standards outside the treatment area, such discharge shall be prevented 

by installing adequate temporary water control measures.

When it is necessary and unavoidable to discharge rotenone treated 

waters to downstream waters, the permittee shall conduct pretreatment 

water quality and biological monitoring. 

Treated waters shall be effectively neutralized and detoxified using 

potassium permanganate so that water quality standards are not 

exceeded below the neutralization zone. For purposes of this section, 

neutralization zone is defined as the downstream waters where 

potassium permanganate has been applied but has not yet fully 

neutralized the rotenone, due to the lag time normally associated with 

detoxification. The neutralization zone is typically considered the 

distance that water can be expected to travel in 20 minutes. Since the 

neutralization zone may contain toxic levels of rotenone and potassium 

permanganate, some fish mortalities may occur in this zone.

Below the neutralization zone, rotenone must be totally neutralized 

and residual potassium permanganate levels maintained at a non-toxic 

level of 1 mg/L, not to exceed 2 mg/L. Live trout cars will be set up 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

9-51 

below the neutralization zone to monitor the effectiveness of 

detoxification measures.

Detoxification procedures must utilize calibrated equipment to achieve 

the minimum effective concentration of potassium permanganate to 

oxidize the rotenone within the neutralization zone. Potassium 

permanganate concentrations must be closely monitored using a field 

calibrated spectrophotometer to keep residual permanganate levels at a 

level that effectively neutralizes rotenone while preventing damage to 

aquatic life downstream of the treatment area and neutralization zone.

2. In order to minimize the discharge of inert ingredients contained in 

liquid rotenone formulations, only powdered rotenone formulations 

shall be utilized, except in very limited cases when the Permittee finds 

it necessary to treat waters that are inaccessible by boat, such as weedy 

shorelines or marshy areas.

3. Monitoring 

The Permittee must conduct monitoring on each water body treated with 

aquatic pesticides to determine the extent and duration of the short-term 

water quality reduction resulting from rotenone applications. The 

Permittee must monitor according to Tables 9-12 and 9-13.

Measures 

Specific Monitoring Requirements 

Sodium chloride & 

Potassium chloride 

• For whole lake treatments or treatments of areas sequestered behind barriers 

within a larger fresh water body, the Permittee must at a minimum measure 

potassium or sodium chloride concentrations at one or more representative 

sampling locations pre-treatment, one, and five days post-treatment to 

determine actual water body concentrations.

Chlorine • The Permittee must monitor for chlorine concentrations under impermeable 

covers on a representative number of sites before removing the covers. 

Permittee may use swimming pool test kits for this purpose.

• If monitoring demonstrates that undercover chlorine concentrations are always 

under 0.5 mg/L before removal (at a representative number of sites and for the 

same chlorine formulation), the Permittee may suspend monitoring upon Ecology 

approval.

Acetic Acid • When removing impermeable covers, monitor pH levels in the receiving water 

before and immediately after cover removal

• When directly spraying the organisms, monitor the pH of receiving waters 

directly adjacent to the organisms immediately before and after treatment. 

Calcium hydroxide/oxide 

(lime) 

For Freshwater Treatments Only

• Measure pH once a day before treatment; once in the morning and once in the 

afternoon during treatment; and for ten days following treatment at a 

representative site within the water body.

• For applications using continuous injection systems, measure pH once in the 

morning and once in the afternoon 

Rotenone and Antimycin-A • See Tables 9-18 – 9-20 for specific monitoring requirements for rotenone and 

antimycin-A. 

Copper • Before applying copper, measure sediment copper concentrations in a 

composite sample of sediment from a representative treatment area 

(composite sample from 5 areas with sediment taken from the top 5 cm of 

sediment and homogenized).

• Measure pH and hardness prior to treatment.

xiv. Public Notice

Ecology includes public notification and treatment area postings in the 

pesticide permits it issues. State law does not require the public notification 

and treatment area postings. They are intended to respect the public’s right to 

know (transparency in government), and to protect the public health and 

welfare by reducing the public’s exposure to pesticides. Ecology strongly 

recommends that the public be provide with public notice of pesticide 

treatments through public notification and treatment area postings. 

The permittee could publish a public notice in a newspaper of general 

circulation in the area where treatment will occur, prior to the first application 

of the season. The newspaper notice could contain:

1. Proposed schedule of treatments for the season. 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

9-64 

2. Common name of the water body to be treated. 

3. Chemicals to be used.

4. Any water use restrictions or precautions 

5. Contact information of the Permittee and any agency staff involved. 

6. Ecology’s regional twenty-four (24) hour Emergency number. 

7. Notification shall explain the project and explain that any treated areas 

will be flagged no more than 48 hours before treatment begins. 

The Permittee is encouraged to use Ecology posting templates contained 

in each pesticide permit to post the treated areas, where feasible, at 100-

foot intervals to 400 feet beyond the boundary of the treatment area. 

Signs posting treatment areas should be posted before treatment 

commenced, but no more than 48 hours before the start of treatment. 

Signs should also be posted in the commonly spoken language of the area 

where treatment is occurring.

Appendix A

Definitions, Abbreviations, and Acronyms

A.1 Definitions

Action Threshold – the point at which pest populations or environmental conditions necessitate 

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 

Agency) that will prevent, destroy, repel or mitigate any pest, or that functions as a plant 

regulator, desiccant, or defoliant within the meaning of FIFRA sec. 2(a). [40 CFR 152.3] 

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 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 effects includes effects that occur within Waters of the United States 

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 

• Other dead or visibly distressed non-target aquatic organisms (amphibians, turtles, 

invertebrates, etc.)

The phrase, toxic or adverse effects, also includes any adverse effects to humans (e.g., skin 

rashes) or domesticated animals that occur either from direct contact with or as a secondary 

effect from a discharge (e.g., sickness from consumption of plants or animals containing 

pesticides) to Waters of the United States that are temporally and spatially related to exposure to 

a pesticide residue (e.g., vomiting, lethargy). 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

A-2 

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 1-1, 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 1-1, calculations should include either the linear extent of 

or the surface area of waters for applications made to Waters of the United States or at water’s 

edge adjacent to Waters of the United States. 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 miles 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 1-1. 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., they are authorized to direct workers to carry out those activities) 

that results in a discharge to Waters of the United States.

Biological Control Agents – these agents are organisms that can be introduced to Operator sites, 

such as herbivores, predators, parasites, and hyperparasites. [Source: 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 dessicant, that (1) is a eucaryotic microorganism including, but not 

limited to, protozoa, algae, and fungi; (2) is a procaryotic 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

mean a pesticide that (1) is a naturally-occurring substance or structurally-similar and 

functionally identical to a naturally-occurring substance; (2) has a history of exposure to humans 

and the environment demonstrating minimal toxicity, or in the case of a synthetically-derived 

biochemical pesticides, is equivalent to a naturally-occurring substance that has such a history; 

and (3) Has a non-toxic mode of action to the target pest(s). [40 CFR 158.2000(a)(1)] Plantincorporated protectant means a pesticidal substance that is intended to be produced and used in 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

covered under the PGP who knows or should have known that an NOI will be required for those 

discharges beginning January 12, 2012. Excluded from this definition are those activities for 

which an NOI is required based solely on that Decision-Maker exceeding an annual treatment 

area threshold. 

Declared Pest Emergency Situation – an event defined by a public declaration by a federal 

agency, state, or local government of a pest problem determined to require control through 

application of a pesticide beginning less than ten days after identification of the need for pest 

control. This public declaration may be based on: 

(1) Significant risk to human health; 

(2) Significant economic loss; or 

(3) Significant risk to:

(i) Endangered species,

(ii) Threatened species,

(iii) Beneficial organisms, or

(iv) The environment.

Discharge of a pollutant – any addition of any “pollutant” or combination of pollutants to 

“Waters of the United States” from any “point source,” or any addition of any pollutant or 

combination of pollutants to the water of the “contiguous zone” or the ocean from any point 

source other than a vessel or other floating craft that is being used as a means of transportation. 

This includes additions of pollutants into Waters of the United States from: surface runoff that is 

collected or channeled by man; discharges through pipes, sewers, or other conveyances, leading 

into privately owned treatment works. [Excerpted from 40 CFR 122.2]

For-Hire Applicator – includes persons who make contractual pesticide applications for which 

they or their employer receives compensation (e.g., lawn care firms, pest control companies). 

Impaired Water (or “Water Quality Impaired Water” or “Water Quality Limited Segment”) – a 

water is impaired for purposes of this permit if it has been identified by a State, Tribe or EPA 

pursuant to Section 303(d) of the Clean Water Act as not meeting applicable State or Tribal

definition includes all land held in trust for an Indian tribe. [18 U.S.C. 1151; 40 CFR 122.2] 

Inert Ingredient – any substance (or group of structurally similar substances if designated by 

the Agency), other than an active ingredient, that is intentionally included in a pesticide product,. 

[40 CFR 152.3] Inert ingredient also means any substance, such as a selectable marker, other 

than the active ingredient, where the substance is used to confirm or ensure the presence of the 

active ingredient, and includes the genetic material necessary for the production of the substance,

these resources overlap with PGP areas of coverage is available at 

www.epa.gov/npdes/pesticides. 

Non-target Organisms – includes the plant and animal hosts of the target species, the natural 

enemies of the target species living in the community, and other plants and animals, including 

vertebrates, living in or near the community that are not the target of the pesticide.

Operator – for the purpose of this permit, means any entity associated with the application of 

pesticides which results in a discharge to Waters of the United States that meets either of the 

following two criteria:

(i) any entity who performs the application of a pesticide or who has day-to-day control of 

the application (i.e., they are authorized to direct workers to carry out those activities); or

(ii) any entity with control over the decision to perform pesticide applications including the 

ability to modify those decisions.

Person – an individual, association, partnership, corporation, municipality, State or Federal 

agency, or an agent or employee thereof. 

Pest – Consistent with 40 CFR 152.5, any organism under circumstances that make it deleterious 

to man or the environment, if it is: 

(a) Any vertebrate animal other than man;

(b) Any invertebrate animal, including but not limited to, any insect, other arthropod, 

nematode, or mollusk such as a slug and snail, but excluding any internal parasite of living 

man or other living animals;

or other living animals and those on or in processed food or processed animal feed, 

beverages, drugs (as defined in FFDCA sec. 201(g)(1)) and cosmetics (as defined in 

FFDCA sec. 201(i)). 

Pest Management Area – The area of land, including any water, for which an Operator has 

responsibility and is authorized to conduct pest management activities as covered by this permit 

(e.g., for an Operator who is a mosquito control district, the pest management area is the total 

area of the district).

Pest Management Measure – 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 

United States.

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 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

A-6 

determined by the 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 bloodstream or 

normally sterile areas of the body and the term ‘‘semi-critical device’’ includes any device that 

contacts intact mucous membranes but which does not ordinarily penetrate the blood barrier or 

otherwise enter normally sterile areas of the body [FIFRA Section 2(u)]. 

The term “pesticide” applies to insecticides, herbicides, fungicides, rodenticides, and various 

other substances used to control pests. The definition encompasses all uses of pesticides 

authorized under FIFRA including uses 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, fishstock 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 US 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] 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

A-7 

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.” [Excerpted from 40 CFR 122.2]

Small Entity - any (1) private enterprise that does not exceed the Small Business Administration 

size standard as identified at 13 CFR 121.201, or (2) local government that serves a population of 

10,000 or less. 

State - means any of the 50 States, the District of Columbia, Guam, the Commonwealth of 

Puerto Rico, the Virgin Islands, American Samoa, the Commonwealth of the Northern Mariana 

Islands, the Trust Territory of the Pacific Islands. 

Target Pest – the organism(s) toward which pest management measures are being directed.

Tier 3 Waters – for antidegradation purposes, pursuant to 40 CFR 131.12(a)(3), Tier 3 waters 

are identified by States or Tribes as having high quality waters constituting an Outstanding 

National Resource Water (ONRW), which may include waters of National Parks and State Parks, 

wildlife refuges, and waters of exceptional recreational or ecological significance.

Total Maximum Daily Loads (TMDLs) – a TMDL is a calculation of 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. [See section 

303(d) of the Clean Water Act and 40 CFR 130.2 and 130.7] 

Treatment Area – the entire area, whether over land or water, where a 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.

Waters of the United States – EPA regulations at 40 CFR 122.2 define Waters of the United 

States as follows:

(a) All waters which are currently used, were used in the past, or may be susceptible to use in 

interstate or foreign commerce, including all waters which are subject to the ebb and flow 

of the tide; 

(b) All interstate waters, including interstate “wetlands;”

(c) All other waters such as intrastate lakes, rivers, streams (including intermittent streams), 

mudflats, sandflats, “wetlands,” sloughs, prairie potholes, wet meadows, playa lakes, or 

natural ponds the use, degradation, or destruction of which would affect or could affect 

interstate or foreign commerce including any such waters:
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

A-8 

(1) Which are or could be used by interstate or foreign travelers for recreational or other 

purposes; 

(2) From which fish or shellfish are or could be taken and sold in interstate or foreign 

commerce; or

(3) Which are used or could be used for industrial purposes by industries in interstate 

commerce;

(d) All impoundments of waters otherwise defined as Waters of the United States under this 

definition; 

(e) Tributaries of waters identified in paragraphs (a) through (d) of this definition; 

(f) The territorial sea; and

(g) “Wetlands” adjacent to waters (other than waters that are themselves wetlands) identified in 

paragraphs (a) through (f) of this definition. [40 CFR 230.3 (s)] 

Waste treatment systems, including treatment ponds or lagoons designed to meet the 

requirements of CWA (other than cooling ponds as defined in 40 CFR 423.11(m) which also 

meet the criteria of this definition) are not Waters of the United States. Waters of the United 

States do not include prior converted cropland. Notwithstanding the determination of an area's 

status as prior converted cropland by any other federal agency, for the purposes of the Clean 

Water Act, the final authority regarding Clean Water Act jurisdiction remains with EPA. [40 

CFR 122.2] 

Delineated Waters of the United States may or may not be wet at the time of discharge; however, 

discharges to such are still considered discharges to Waters of the United States. Also, this 

permit refers to the term “Waters of the United States’ to identify those point source discharges 

required to obtain NPDES permit coverage. Any modification to the regulatory definition of 

“Waters of the United States” at 40 CFR 122.2 during the effective term of this permit becomes 

the legal standard for identifying those point source discharges required to obtain NPDES permit 

coverage consistent with the effective date of such regulations. See EPA’s website for up-todate guidance on identifying Waters of the United States.

Water Quality Impaired – See ‘Impaired Water’.

Water Quality Standards – A water quality standard defines the water quality goals of a water 

body, or portion thereof, 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 antidegradation 

policy and implementation procedures. See P.U.D. o. 1 of Jefferson County et al v. Wash Dept of 

Ecology et al, 511 US 701, 705 (1994). States, 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)2 and 303(c)). Where necessary, EPA has the authority to 

promulgate federal water quality standards.

Wetlands – means those areas that are inundated or saturated by surface or groundwater at a

Appendix B. 

Standard Permit Conditions

Standard permit conditions in Appendix B generally are consistent with the permit provisions 

required in 40 CFR 122.41 but are modified to reflect the nature of discharges covered under this 

general permit.

B.1 Duty to Comply

Operators must comply with all conditions of this permit. Any permit noncompliance constitutes 

a violation of the CWA and is grounds for enforcement action; for permit termination, revocation 

and reissuance, or modification; or for denial of a permit renewal application.

A. Operators must comply with effluent standards or prohibitions established under CWA 

section 307(a) for toxic pollutants within the time provided in the regulations that establish 

these standards, even if the permit has not yet been modified to incorporate the 

requirement.

B. Penalties for Violations of Permit Conditions: EPA will periodically adjust for inflation the 

civil and administrative penalties listed below in accordance with the Civil Monetary 

Penalty Inflation Adjustment Rule (61 FR 252, December 31, 1996, pp. 69359–69366, as 

corrected in 62 FR 54, March 20, 1997, pp.13514–13517) as mandated by the Debt 

Collection Improvement Act of 1996. This rule allows EPA’s penalties to keep pace with 

inflation. The Agency is required to review its penalties at least once every 4 years 

thereafter and to adjust them as necessary for inflation according to a specified formula. 

The civil and administrative penalties following were adjusted for inflation starting in 

1996. 

1. Criminal Penalties

1.1 Negligent Violations. The CWA provides that any person who negligently 

violates permit conditions implementing sections 301, 302, 306, 307, 308, 318, or 

405 of the Act is subject to criminal penalties of not less than $2,500 nor more 

than $25,000 per day of violation, or imprisonment of not more than one year, or 

both. In the case of a second or subsequent conviction for a negligent violation, a 

person will be subject to criminal penalties of not more than $50,000 per day of 

violation or by imprisonment of not more than two years, or both. 

1.2 Knowing Violations. The CWA provides that any person who knowingly violates 

permit conditions implementing sections 301, 302, 306, 307, 308, 318, or 405 of 

the Act is subject to a fine of not less than $5,000 nor more than $50,000 per day 

of violation, or by imprisonment for not more than 3 years, or both. In the case of 

a second or subsequent conviction for a knowing violation, a person will be 

subject to criminal penalties of not more than $100,000 per day of violation, or 

imprisonment of not more than 6 years, or both. 

1.3 Knowing Endangerment. The CWA provides that any person who knowingly 

violates permit conditions implementing sections 301, 302, 306, 307, 308, 318, or 

405 of the Act and who knows at that time that he or she is placing another person 

in imminent danger of death or serious bodily injury will upon conviction be 

subject to a fine of not more than $250,000 or by imprisonment of not more than 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

B-2 

15 years, or both. In the case of a second or subsequent conviction for a knowing 

endangerment violation, a person will be subject to a fine of not more than 

$500,000 or by imprisonment of not more than 30 years, or both. An organization, 

as defined in section 309(c)(3)(B)(iii) of the Act, will, upon conviction of 

violating the imminent danger provision, be subject to a fine of not more than 

$1,000,000 and can fined up to $2,000,000 for second or subsequent convictions. 

1.4. False Statement. The CWA provides that any person who falsifies, tampers with, 

or knowingly renders inaccurate any monitoring device or method required to be 

maintained under this permit will, upon conviction, be punished by a fine of not 

more than $10,000, or by imprisonment for not more than 2 years, or both. If a 

conviction of a person is for a violation committed after a first conviction of such 

person under this paragraph, punishment is a fine of not more than $20,000 per 

day of violation, or by imprisonment of not more than 4 years, or both. The Act 

further provides that any person who knowingly makes any false statement, 

representation, or certification in any record or other document submitted or 

required to be maintained under this permit, including monitoring reports or 

reports of compliance or noncompliance will, upon conviction, be punished by a 

fine of not more than $10,000 per violation, or by imprisonment for not more than 

6 months per violation, or by both. 

2. Civil Penalties. The CWA provides that any person who violates a permit condition 

implementing sections 301, 302, 306, 307, 308, 318, or 405 of the Act is subject to a 

civil penalty not to exceed the maximum amounts authorized by Section 309(d) of the 

Act and the Federal Civil Penalties Inflation Adjustment Act (28 U.S.C. 2461 note) as 

amended by the Debt Collection Improvement Act (31 U.S.C. 3701 note) (currently 

$37,500 per day for each violation). 

3. Administrative Penalties. The CWA provides that any person who violates a permit 

condition implementing sections 301, 302, 306, 307, 308, 318, or 405 of the Act is 

subject to an administrative penalty, as follows 

3.1 Class I Penalty. Not to exceed the maximum amounts authorized by CWA section 

309(g)(2)(A) and the Federal Civil Penalties Inflation Adjustment Act (28 U.S.C. 

2461 note) as amended by the Debt Collection Improvement Act (31 U.S.C. 3701 

note) (currently $11,000 per violation, with the maximum amount of any Class I 

penalty assessed not to exceed $37,500). 

3.2 Class II Penalty. Not to exceed the maximum amounts authorized by CWA 

section 309(g)(2)(B) and the Federal Civil Penalties Inflation Adjustment Act 

(28 U.S.C. 2461 note) as amended by the Debt Collection Improvement Act 

(31 U.S.C. 3701 note) (currently $11,000 per day for each day during which the 

violation continues, with the maximum amount of any Class II penalty not to 

exceed $157,500). 

B.2 Duty to Reapply

Except as otherwise provided for in Part 1.2.4 of the permit, if an Operator wishes to continue an 

activity regulated by this permit after the expiration date of this permit, the Operator must apply 

for and obtain authorization as required by the new permit once EPA issues it. 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

B-3 

B.3 Need to Halt or Reduce Activity Not a Defense

It will not be a defense for an Operator in an enforcement action that it would have been 

necessary to halt or reduce the permitted activity to maintain compliance with the conditions of 

this permit.

B.4 Duty to Mitigate

Operators must take all reasonable steps to minimize or prevent any discharge in violation of this 

permit, which has a reasonable likelihood of adversely affecting human health or the 

environment. 

B.5 Proper Operation and Maintenance

Operators must at all times properly operate and maintain all facilities and systems of treatment 

and control (and related appurtenances) which the Operators installs or uses to achieve 

compliance with the conditions of this permit. Proper operation and maintenance also includes 

adequate laboratory controls and appropriate quality assurance procedures. This provision 

requires the operation of backup or auxiliary facilities or similar systems which the Operator 

installs only when the operation is necessary to achieve compliance with the conditions of this 

permit.

B.6 Permit Actions

This permit may be modified, revoked and reissued, or terminated for cause. An Operator’s 

filing of a request for a permit modification, revocation and reissuance, or termination, or a 

notification of planned changes or anticipated noncompliance does not stay any permit condition. 

B.7 Property Rights

This permit does not convey any property rights of any sort, or any exclusive privileges. 

B.8 Duty to Provide Information

Operators must furnish to EPA or an authorized representative (including an authorized 

contractor acting as a representative of EPA), within a reasonable time, any information that 

EPA may request to determine whether cause exists for modifying, revoking and reissuing, or 

terminating this permit or to determine compliance with this permit. Operators must also furnish 

to EPA or an authorized representative upon request, copies of records required to be kept by this 

permit.

B.9 Inspection and Entry

Operators must allow EPA, or an authorized representative (including an authorized contractor 

acting as a representative of EPA), upon presentation of credentials and other documents as may 

be required by law, to do the following: 

A. Enter upon an Operator’s premises where a regulated activity is located or conducted, or 

where records must be kept under the conditions of this permit; 

B. Have access to and copy, at reasonable times, any records that must be kept under the 

conditions of this permit; 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

B-4 

C. Inspect at reasonable times any facilities, equipment (including monitoring and control 

equipment), practices, or operations regulated or required under this permit; and 

D. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or 

as otherwise authorized by the CWA, any substances or parameters at any location. 

B.10 Monitoring and Records

A. Operators must retain records of all reports required by this permit, and records of all data 

used to complete the NOI for this permit, for a period of at least 3 years from the date the 

permit expires or the date the Operator’s authorization is terminated. That period may be 

extended by request of EPA at any time.

[As written, this permit does not require Operators to perform the type of sample collection 

and monitoring described in the following sections of this appendix, B.10.B through 

B.10.F. However, where EPA requires any monitoring, consistent with Part 1.2.3 of the 

Permit, the sample collection and monitoring requirements in B.10.B through B.10.F of 

this appendix apply to those Operators that collect samples.] 

B. Samples and measurements taken for the purpose of monitoring must be representative of 

the volume and nature of the monitored activity.

C. 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 EPA 

at any time.

D. Records of monitoring information must include the following: 

1. The date, exact place, and time of sampling or measurements;

2. The individual(s) who performed the sampling or measurements; 

3. The date(s) analyses were performed

4. The individual(s) who performed the analyses; 

5. The analytical techniques or methods used; and 

6. The results of such analyses

E. Monitoring must be conducted according to test procedures approved under 40 CFR Part 

136, unless other test procedures have been specified in the permit. 

F. The CWA provides that any person who falsifies, tampers with, or knowingly renders 

inaccurate any monitoring device or method required to be maintained under this permit 

will, upon conviction, be punished by a fine of not more than $10,000, or by imprisonment 

for not more than 2 years, or both. If a conviction of a person is for a violation committed 

after a first conviction of such person under this paragraph, punishment is a fine of not 

more than $20,000 per day of violation, or by imprisonment of not more than 4 years, or 

both. 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

B-5 

B.11 Signatory Requirements

A. All applications, including NOIs, must be signed as follows: 

1. For a corporation: By a responsible corporate officer. For the purpose of this 

subsection, a responsible corporate officer means: (i) a president, secretary, treasurer, 

or vice-president of the corporation in charge of a principal business function, or any 

other person who performs similar policy- or decision-making functions for the 

corporation, or (ii) the manager of one or more manufacturing, production, or operating 

facilities, provided, the manager is authorized to make management decisions that 

govern the operation of the regulated activity including having the explicit or implicit 

duty of making major capital investment recommendations, and initiating and directing 

other comprehensive measures to assure long-term environmental compliance with 

environmental laws and regulations; the manager can ensure that the necessary systems 

are established or actions taken to gather complete and accurate information for permit 

application requirements; and where authority to sign documents has been assigned or 

delegated to the manager in accordance with corporate procedures.

2. For a partnership or sole proprietorship: By a general partner or the proprietor, 

respectively; or

3. For a municipality, state, federal, or other public agency: By either a principal 

executive officer or ranking elected official. For purposes of this subsection, a principal 

executive officer of a federal agency includes (i) the chief executive officer of the 

agency, or (ii) a senior executive officer having responsibility for the overall operations 

of a principal geographic unit or the agency (e.g., Regional Administrator of EPA). 

B. Any Pesticide Discharge Management Plan (PDMP), including changes to the PDMP to 

document any corrective actions taken as required by Part 6, and all reports submitted to 

EPA, must be signed by a person described in Appendix B, Subsection B.11.A above or by 

a duly authorized representative of that person. A person is a duly authorized representative 

only if the following are true: 

1. The authorization is made in writing by a person described in Appendix B, Subsection 

B.11.A; 

2. The authorization specifies either an individual or a position having responsibility for 

the overall operation of the regulated activity such as the position of superintendent, 

position of equivalent responsibility, or an individual or position having overall 

responsibility for environmental matters for the company. (A duly authorized 

representative may thus be either a named individual or any individual occupying a 

named position); and 

3. The signed and dated written authorization is included in the PDMP. A copy must be 

submitted to EPA, if requested. 

C. All other changes to the PDMP, and other compliance documentation required under this 

permit, must be signed and dated by the person preparing the change or documentation.

D. Changes to Authorization. If an authorization under Appendix B, Subsection B.11.A is no 

longer accurate because the application activities have been purchased by a different entity, 

a new NOI satisfying the requirements of Subsection B.11.A must be submitted to EPA. 

However, if the only change that is occurring is a change in contact information or a 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

B-6 

change in the Operator’s address, the Operator need only make a modification to the 

existing NOI submitted for authorization. 

E. Any person signing documents in accordance with Appendix B, Subsections B.11.A or 

B.11.B above must include the following certification: 

“I certify under penalty of law that this document and all attachments were prepared 

under my direction or supervision in accordance with a system designed to assure that 

qualified personnel properly gathered and evaluated the information contained therein. 

Based on my inquiry of the person or persons who manage the system, or those persons 

directly responsible for gathering the information, the information contained is, to the 

best of my knowledge and belief, true, accurate, and complete. I am aware that there 

are significant penalties for submitting false information, including the possibility of 

fine and imprisonment for knowing violations.” 

F. The CWA provides that any person who knowingly makes any false statement, 

representation, or certification in any record or other document submitted or required to be 

maintained under this permit, including monitoring reports or reports of compliance or 

noncompliance will, upon conviction, be punished by a fine of not more than $10,000 per 

violation, or by imprisonment for not more than 6 months per violation, or by both. 

B.12 Reporting Requirements

A. Anticipated noncompliance. Operators must give advance notice to EPA of any planned 

changes in the permitted activity which may result in noncompliance with permit 

requirements.

B. Transfers. This permit is not transferable to any person except after notice to EPA. Where 

an Operator wants to transfer coverage under the permit to a new Operator, the original 

Operator (i.e., the first Operator) must submit a Notice of Termination pursuant to Part 

1.2.5. The new Operator must submit a NOI in accordance with Part 1.2. See also 

requirements in Appendix B, Subsections B.11.B and B.11.D. 

C. Pesticide Monitoring Reports. This permit does not require Operators to report monitoring 

results routinely; however, EPA may, pursuant to Part 1.2.3, require certain Operators to 

monitor and report such results. In such instances, provisions of B.12.C apply. 

1. Monitoring data must be submitted to EPA at the appropriate Regional address 

identified in Part 9.2. 

2. If an Operator monitors any pollutant more frequently than required using test 

procedures approved under 40 CFR Part 136 or as otherwise specified by EPA, the 

results of this monitoring must be included in reporting of monitoring data submitted to 

EPA.

3. Calculations for all limitations that require averaging of measurements must use an 

arithmetic mean unless otherwise specified by EPA.

D. Compliance schedules. Reports of compliance or noncompliance with, or any progress 

reports on, interim and final requirements contained in any compliance schedule of this 

permit must be submitted no later than 14 days following each schedule date. 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

B-7 

E. Twenty-four hour reporting. 

1. In addition to adverse incident and spill reporting requirements in Parts 6.4 and 6.5, 

respectively, Operators must report any noncompliance which may endanger health or 

the environment. Any information must be provided orally within 24 hours from the 

time the Operator becomes aware of the circumstances. A written submission must also 

be provided within 5 days of the time the Operator becomes aware of the 

circumstances. The written submission must contain a description of the 

noncompliance and its cause; the period of noncompliance, including exact dates and 

times, and if the noncompliance has not been corrected, the anticipated time it is 

expected to continue; and steps taken or planned to reduce, eliminate, and prevent 

reoccurrence of the noncompliance.

2. For purposes of this permit, Operators must submit a 24-hour report under this section 

for any upset, as defined in Appendix B, Subsection B.13, which exceeds any effluent 

limitation in the permit.

3. EPA may waive the written report on a case-by-case basis for reports under Appendix 

B, Subsection B.12.E.2 if the oral report has been received within 24 hours. 

F. Other noncompliance. Operators must report all instances of noncompliance not reported 

under Appendix B, Subsections 12.A, 12.D, and 12.E, at the time any applicable annual or 

monitoring reports are submitted. The reports must contain the information listed in 

Appendix B, Subsection 12.E.1. 

G. Other information. Where an Operator becomes aware of its failure to submit any relevant 

facts in a permit application, or submitted incorrect information in a permit application or 

in any report to the Permitting Authority, the Operator must promptly submit such facts or 

information. 

B.13 Upset

A. Definition. Upset means an exceptional incident in which there is unintentional and 

temporary noncompliance with technology-based permit effluent limitations because of 

factors beyond the Operator’s reasonable control. An upset does not include 

noncompliance to the extent caused by operational error, improperly designed treatment 

facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or 

improper operation. See 40 CFR 122.41(n)(1). 

B. Effect of an upset. An upset constitutes an affirmative defense to an action brought for 

noncompliance with such technology-based permit effluent limitations if the requirements 

of Appendix B, Subsection B.13.C are met. Any determination made during administrative 

review of claims that noncompliance was caused by an upset, and before an action for 

noncompliance, is not final administrative action subject to judicial review. See 40 CFR 

122.41(n)(2). 

C. Conditions necessary for a demonstration of upset. See 40 CFR 122.41(n)(3). An Operator 

who wishes to establish the affirmative defense for an upset must demonstrate, through 

properly signed, contemporaneous operating logs, or other relevant evidence that 

1. An upset occurred and that the Operator can identify the cause(s) of the upset; 

2. The permitted activity was at the time being properly operated; and
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

B-8 

3. The Operator submitted notice of the upset as required in Appendix B, Subsection 

B.12.E.2 (24 hour notice). 

4. The Operator complied with any remedial measures required under Appendix B, 

Subsection B.4. 

D. Burden of proof. In any enforcement proceeding, the Operator, as the one seeking to 

establish the occurrence of an upset, has the burden of proof. See 40 CFR 122.41(n)(4).

Pesticide General Permit is desired. Copy this section for non-electronic submissions. 

Pest Management Area #___ of ##___ 

1. Identify the criterion for which you are eligible for permit coverage as it applies to Federally Listed Threatened or Endangered Species (i.e., Species) 

and/or Federally Designated Critical Habitat (i.e., Habitat) (check one): 

a. Pesticide application activities will not result in a point source discharge to one or more Waters of the United States containing National Marine 

Fisheries Service (NMFS) Listed Resources of Concern, as defined in Appendix A, of the PGP. 

b. Pesticide application activities for which permit coverage is being requested will discharge to one or more Waters of the United States containing 

NMFS Listed Resources of Concern, as defined in Appendix A of the PGP, but consultation with NMFS under Section 7 of the Endangered Species 

Act (ESA) has been concluded for pesticide application activities covered under the PGP. Consultations can be either formal or informal, and would 

have occurred only as a result of a separate federal action. The consultation addressed the effects of pesticide discharges and discharge-related 

activities on federally-listed threatened or endangered species and federally-designated critical habitat, and must have resulted in either: 

i. A biological opinion from NMFS finding no jeopardy to federally-listed species and no destruction/adverse modification of federally-designated 

critical habitat; or 

ii. Written concurrence from NMFS with a finding that the pesticide discharges and discharge-related activities are not likely to adversely affect 

federally-listed species or federally-designated critical habitat. 

c. Pesticide application activities for which permit coverage is being requested will discharge to one or more Waters of the United States containing 

NMFS Listed Resources of Concern, as defined in Appendix A of the PGP, but all “take” of these resources associated with such pesticide 

application activities has been authorized through NMFS’ issuance of a permit under section 10 of the ESA, and such authorization addresses the 

effects of the pesticide discharges and discharge-related activities on federally-listed species and federally-designated critical habitat. (The term 

“take” means to harass, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct. See Section 3 of the 

Endangered Species Act, 16 U.S.C. § 1532 (19).) 

d. Pesticide application activities were, or will be, discharged to one or more Waters of the United States containing NMFS Listed Resources of 

Concern, as defined in Appendix A of the PGP, but only in response to a Declared Pest Emergency Situation. 

e. Pesticide application activities for which permit coverage is being requested in the NOI will discharge to one or more Waters of the United States 

containing NMFS Listed Resources of Concern, as defined in Appendix A of the PGP. Eligible discharges include those where the Decision-maker 

includes in the NOI written correspondence from NMFS that pesticide application activities performed consistent with appropriate measures will 

avoid or eliminate the likelihood of adverse effects to NMFS Listed Resources of Concern. 

f. Pesticide application activities for which permit coverage is being requested in the NOI will discharge to one or more Waters of the United States 

containing NMFS Listed Resources of Concern, as defined in Appendix A of the PGP. Eligible discharges include those from pesticide application 

activities that are demonstrated by the Decision-maker as not likely to adversely affect NMFA Listed Resources of Concern or that the pest poses a 

greater threat to the NMFS Listed Resources of Concern than does the discharge of the pesticide. 

2. If you checked criterion d or criterion f above, provide the following information for all discharges to Waters of the United States containing NMFS Listed 

Resources of Concern identified within the pest management area for which permit coverage is being requested. For discharges pursuant to criterion d, 

Declared Pest Emergency Situations, information for items a through g should also include any discharges that have already occurred prior to NOI 

submission as well as the activities you performed in the 15 day period before submission of this NOI was required. In some cases, implementation of 

pest management measures as specified in the permit involves a degree of “adaptive management” such that exact timing and quantities of applications 

cannot be determined in advance for the duration of the permit. In such cases, the permittee must provide the required information to the extent feasible 

and consistent with the implementation of the selected pest management measures. 

a. Describe the location of the pest management area in detail or provide a map of the location: 

b. Pest(s) to be controlled: 

____________________________________________________________________________________________________________________ 

c. 

___________________________________________________

Pesticide product(s) to be discharged and method of application:

d. Planned quantity and rate of discharge(s) for each method of application: _________________________________________________________ 

e. Number of planned discharges: ____________ 

f. Approximate date(s) of planned discharge(s): _______________________________________________________________________________ 

g. Your rationale supporting your determination that you meet the criterion for which you are submitting this NOI, including appropriate measures to be 

undertaken to avoid or eliminate the likelihood of adverse effects. For certifications pursuant to Criterion D, indicate whether the discharge is likely to 

adversely affect NMFS Listed Resources of Concern and, if so, any feasible measures to avoid or eliminate such adverse effects (attach additional

One NOI can be submitted for multiple pest management areas in a state for which 

you are seeking permit coverage; however, no more than one state can be included on 

any single NOI form. 

When to File the NOI Form? 

Do not file your NOI until you have obtained and thoroughly read a copy of the permit. 

A copy of the permit is on EPA’s website (www.epa.gov/npdes/pesticides).The permit 

describes procedures to ensure your eligibility, prepare your Pesticide Discharge 

Management Plan (PDMP), and complete the NOI form questions—all of which must 

be done before you sign the NOI certification statement attesting to the accuracy and 

completeness of your NOI. You will also need a copy of the permit once you have 

obtained coverage so that you can comply with the implementation requirements of 

the permit. Note: PDMP is not required for 1) any application made in response to a 

Declared Pest Emergency Situation, as defined in Appendix A of the permit; and 2) 

any Decision-maker that is required to submit an NOI solely because their application 

results in a point source discharge to Waters of the United States containing NMFS 

Listed Resources of Concern, as defined in Appendix A of the permit. 

All eligible discharges are authorized for permit coverage through January 12, 

2012 without submission of an NOI. For any discharges after January 12, 2012, 

Decision-makers meeting the eligibility requirements identified in the Part 1.1of the 

permit and Table 1 must submit a complete and accurate NOI according to Tables 2, 

and 3 and consistent with the requirements of the Part 1.2 of the permit. For example, 

for discharges occurring on or before January 12, 2012 but continuing after January 

12, 2012, NOIs are due no later than January 3, 2012 to ensure uninterrupted 

coverage. 

Table 2. NOI Submittal Deadlines and Discharge Authorization Dates for 

Discharges from the Application of Pesticides 1 

After January 12, 2012, any eligible discharge for which an NOI is required must 

submit an NOI consistent with the earliest due date identified below. If EPA receives 

an NOI on or before January 2, 2012 (or on or before December 12, 2011, for 

discharges to Waters of the United States containing NMFS Listed Resources of 

Concern), uninterrupted coverage continues.2 NOI due dates for any discharges 

occurring on or after January 12, 2012 are as follows:

1 State, territory and tribal specific requirements in addition to the requirements in this 

table are provided in Part 9.0. 2	 On the basis of a review of an NOI or other information, EPA may delay 

authorization to discharge beyond any timeframe identified in Table 2, determine 

that additional technology-based and/or water quality-based effluent limitations or 

other conditions are necessary, or deny coverage under this permit and require 

submission of an application for an individual NPDES permit, as detailed in Part 1.3 

of the permit. 3	 Within 30 days after EPA posts on the Internet receipt of a complete and accurate 

NOI, for those areas with NMFS Listed Resources of Concern, as defined in 

Appendix A of the permit, NMFS will provide EPA with a determination as to 

whether it believes the eligibility criterion of “not likely to adversely affect listed 

species or designated critical habitat” has been met, could be met with conditions 

that NMFS identifies, or has not been met. EPA expects to rely on NMFS’ 

determination in deciding whether to withhold authorization. If NMFS does not 

provide EPA with this information within 30 days of EPA posting on the Internet 

receipt of a complete and accurate NOI, the discharges will be authorized 30 days 

after EPA posts on the Internet receipt of a complete NOI. 4	 In any Declared Pest Emergency Situation in areas with Waters of the United 

States containing NMFS Listed Resources of Concern, NMFS will have 30 days 

after submission of an NOI to provide EPA with a determination as to whether the 

eligibility criteria of “not likely to adversely affect listed species or designated critical 

habitat” has been met, could be met with conditions that NMFS identifies, or has 

not been met. EPA expects to rely on NMFS’ determination in deciding whether to 

allow continued permit coverage and if additional conditions are necessary. If 

NMFS does not provide EPA with a recommendation within 30 days of EPA posting 

on the Internet receipt of a complete and accurate NOI, authorization for these 

discharges will continue. If EPA identifies additional permit conditions, or includes 

additional permit conditions recommended by NMFS, as necessary to qualify 

discharges as eligible for coverage beyond 60 days under the PGP, those 

conditions remain in effect for the life of the permit. 5	 EPA may authorize certain discharges in less than 30 days, but no fewer than 10 

days, for any discharges authorized under Criterion B, C, or E of Part 1.1.2.4 (for 

which NMFS has already evaluated the effects of these discharges).

Where to File the NOI Form 

The Decision-maker must prepare and submit the NOI using EPA’s electronic Notice 

of Intent system (eNOI) available on EPA’s website 

(www.epa.gov/npdes/pesticides/enoi) unless eNOI is otherwise unavailable or the 

Decision-maker has filed a waiver from the requirement to use eNOI for submission of 

the NOI. The Electronic Submission Waiver is at the top of this form. Decision-makers 

waived from the requirement to use eNOI for NOI submission must certify to EPA on 

this form that use of eNOI will incur undue burden or expense over the use of the 

paper NOI form and then provide a basis for that determination. 

EPA will immediately post on the pesticides eNOI Website all NOIs received. Late 

NOIs will be accepted, but authorization to discharge will not be retroactive. 

If you file a waiver from using eNOI; you must send the NOI to one of the addresses 

listed below.

(optional), name, and e-mail address. Correspondence will be sent to this address. 

Section C. Pest Management Area: Information for each Pest Management Area 

for which coverage under EPA’s Pesticide General Permit is desired. 

1. Indicate whether you are submitting an NOI for multiple pest management areas. A 

pest management area is the area of land, including any water, for which you have 

responsibility and are authorized to conduct pest management activities as covered 

by this permit (e.g., if you are a mosquito control district, your pest management 

area is the total area of the district). You must complete a Section C for each pest 

management area. If you are submitting an NOI for only one area, enter “1” of “1.” If 

you are submitting NOIs for multiple pest management areas, enter the number for 

the NOI for which you are requesting coverage followed by the total number of pest 

management areas for which you are requesting coverage. Enter the name of the 

pest management area. Attach a map of the pest management area or describe the 

location of the pest management area in the space provided. 

2. Indicate whether pesticide application will occur on Indian County Lands, and if so, 

provide the name of the reservation, if applicable. 

3. Indicate whether pesticide application will occur on a Federal Facility, as defined in 

Appendix A of the permit. 

4. Enter the mailing address of the contact person for the pest management area. If 

this address is the same as the Decision-maker’s mailing address, indicate that by 

checking the box. If it is a different address, enter the mailing address, telephone 

number, fax number (optional), contact name, and e-mail address. 

5. Indicate the pesticide use patterns for the pest management area for which the NOI 

is required. For additional information regarding pesticide use patterns, see Part 

1.1.1 of the permit. Check all the use patterns that apply to the pest management 

area. 

6.	 Indicate if permit coverage is being requested for all Waters of the United States 

within the pest management area or if permit coverage is being requested to 

specific Waters of the United States within the pest management area. If specific 

waters are being requested, write the names of the waterbodies. If permit coverage 

is being requested for all waters of the United States within the pest management 

area except for specific waterbodies, name those specific waterbodies in the space 

provided. EPA’s Water Locator Tool can help you identify the closest receiving 

water to your facility (http://cfpub.epa.gov/npdes/stormwater/tmdltool.cfm). 

7.	 Indicate if permit coverage is being requested to discharge to a Tier 3 (Outstanding 

National Resource Water) Water of the United States. If yes, write the name(s) of 

the Tier 3 water(s) in the space provided. Describe and demonstrate why it is 

necessary to apply the pesticide discharge to protect the water quality, 

environment, and/or public health and that any such discharge will not degrade 

water quality or will degrade water quality only on a short-term or temporary basis. 

8. Verify that waters within the pest management area are either not impaired by 

substances which are either active ingredients in the pesticide planned for use or 

degradates of such active ingredients, OR that evidence shows that the target 

waters in question are no longer impaired. See Part 1.1.2.1 of the permit for more 

information on discharges to Water Quality Impaired Waters. 

Section D. Endangered Species Protection. Complete Section D for each Pest 

Management Area for which coverage under EPA’s PGP is desired. 

Identify the Pest Management Areas, corresponding to those in Part C. 

1. Coverage under the permit is available only for discharges and discharge-related 

activities, as defined in Appendix A of the permit, that are not likely to jeopardize 

the continued existence of any species that are federally- listed as endangered or 

threatened (“listed”) under the Endangered Species Act (ESA) and not likely to 

result in the adverse modification or destruction of habitat that is federallydesignated as critical under the ESA (“critical habitat”) except as provided in 

criterion b, c, and for at least 60 days, d, below. For a subset of listed species and 

critical habitat, identified as NMFS Listed Resources of Concern and defined in 

Appendix A, there are specific criteria for determining eligibility. To demonstrate 

eligibility, you must meet one or more of the six criteria (a-f) for the entire term of 

coverage under the permit. 

2. If you checked criterion d or criterion f, you are required to provide a description of 

the location of the pest management area or a map of the location, the pest(s) to be 

controlled, pesticide product(s) to be discharged and method of application, 

planned quantity and rate of discharge(s) for each application method, number of 

planned discharges, approximate date(s) of planned discharge(s), and the rational 

supporting your determination that you meet the criterion for which the Decisionmaker is submitting this NOI and documentation demonstrating the finding of “not 

likely to adversely affect.” If you certify under criteria f and do not hear from EPA 

within 30 days, you may assume your discharge is authorized. For certifications 

pursuant to Criterion d, indicate whether the discharge is likely to adversely affect 

NMFS Listed Resources of Concern and, if so, any feasible measures to avoid or 

eliminate such adverse effects. If you are certifying under criterion d (which allows 

you to discharge 15 days before you even submit your NOI), your NOI should 

describe both the pest emergency activities you plan to do after you submit your 

NOI as well as the activities you performed in that 15 day period before you had to 

submit the NOI. See Part 1.1.2.4 of the permit for more information regarding 

Endangered and Threatened Species and Critical Habitat Protection. If you certify 

under criterion d and do not hear from EPA, you may assume that permit 

authorization continues unless notified otherwise.EPA may authorize certain 

discharges in less than 30 days, but no fewer than 10 days, for any discharges 

authorized under criterion b, c, or e (for which NMFS has already evaluated the 

effects of these discharges). If you certify under one of these criteria and do not 

hear from EPA within 30 days, you may assume your discharge is authorized. 

Section E. Certification 

Enter the certifier’s printed name and title. Sign and date the form. For more 

information about the certification statement and signature, see Appendix B of the 

permit. (CAUTION: An unsigned or undated form will not be accepted.) Federal

INSTRUCTIONS FOR COMPLETING THE NOTICE OF TERMINATION (NOT) OF COVERAGE UNDER THE PESTICIDE GENERAL PERMIT (PGP) FOR
 

DISCHARGES FROM THE APPLICATION OF PESTICIDES
 

Who Must File an NOT Form with EPA? 

Any Operator required to submit a Notice of Intent (NOI) is required to submit a 

Notice of Termination (NOT) to end coverage under this permit. However, if EPA 

notifies the Operator to apply for an NPDES individual permit or alternative general 

permit, coverage under this permit terminates automatically. Dischargers 

automatically covered under this permit as identified in Part 1.2.3 of the permit are 

likewise automatically terminated upon permanent cessation of discharge consistent 

with any of the criteria identified in Part 1.2.5.3 of the permit. As required in the 

permit, only certain Operators that are also Decision-makers must submit NOIs. 

If you have questions about whether you need to file an NOT or questions about 

completing the form, see www.epa.gov/npdes/pesticides or contact the NOI Center 

toll free at 866-352-7755. 

When to File the NOT Form? 

Operators must file the NOT form within 30 days after one or more of the conditions 

in Part 1.2.5.2 of the permit have been met. 

Where to File the NOT Form? 

Consistent with Part 1.2.5.1 of the permit, the Operator must submit the NOT using 

EPA’s electronic Notice of Intent (eNOI) System available on EPA’s website 

(www.epa.gov/npdes/pesticides/enoi) unless eNOI is otherwise unavailable or the 

Operator files a waiver from the requirement to use eNOI for submission of the 

NOT. The Electronic Submission Waiver is at the top of this NOT form. An Operator 

waived from the requirement to use eNOI for any NOT submission must certify to 

EPA on this form that use of eNOI will incur undue burden or expense over the use 

of the paper NOT form and then provide a basis for that determination. 

Filing electronically is the fastest way to terminate permit coverage and help ensure 

that your NOT is complete. 

If you do file a waiver from using eNOI; you must send the NOT to one of the 

addresses listed below.

Instructions for Completing the Annual Report Form for the Pesticide General Permit (PGP) for
 

Discharges from the Application of Pesticides
 

Who Must File an Annual Report with EPA?	 Section A. General Information 

Any Operator that is a Decision-maker required to submit a Notice of Intent (NOI) 

and is a large entity as defined in Appendix A of the permit and any Decision-maker 

required to submit an NOI solely because of their application results in a discharge 

to Waters of the United States containing NMFS Listed Resources of Concern, must 

submit an annual report to EPA each calendar year. Once required to submit an 

annual report for one year, an annual report must be filed each subsequent year of 

this permit whether or not you have discharges from the application of pesticides in 

accordance with Section 7.6 of the permit. 

When to File an Annual Report? 

Any Operator required to file an annual report must submit the annual report no later 

than February 15 of the following year for all pesticide activities covered under this 

permit occurring during the previous calendar year. If the Operator is required to 

submit an NOI based on an annual treatment area threshold, the annual report 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 point at which the 

Operator exceeded the annual treatment area threshold. If the Operator first 

exceeds an annual treatment area threshold after December 1 in a calendar year, 

an annual report is not required for that first partial year but annual reports are 

required thereafter, with the first annual report submitted also including information 

from the first partial year. 

When Operator terminates permit coverage, as specified in Part 1.2.5 of the permit, 

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 February 15 of the following year. 

Where to File the Annual Report? 

The Operator must prepare and submit the Annual Report using EPA’s electronic 

Notice of Intent (eNOI) system available on EPA’s website 

(www.epa.gov/npdes/pesticides/enoi) unless eNOI is otherwise unavailable or the 

Operator has filed a waiver from the requirement to use eNOI for submitting the 

Annual Report. The Electronic Submission Waiver is at the top of this form. Any 

Operator waived from the requirement to use eNOI for Annual Report submission 

must certify to EPA on this form that use of eNOI will incur undue burden or 

expense over the use of the paper Annual Report form and then provide a basis for 

that determination. 

If you do file a waiver from using eNOI; you must send the Annual Report to one of 

the addresses listed below.

Instructions for Completing and Submitting the Thirty (30) Day Adverse Incident Written Report for the Pesticide 

General Permit (PGP) for Discharges from the Application of Pesticides 

Who Must Submit a 30-day Adverse Incident Report? 

All Operators who observe or are otherwise made aware of a reportable adverse 

incident pursuant to Part 6.4 of the permit must submit on adverse incident report. 

However, even for those identified adverse incidents for which the Operator is not 

required to report, EPA recommends that Operators consider using this form to 

document the incident and the rationale for why reporting of the adverse incident is 

not required. This information may be useful to support a rationale should this 

determination be questioned. 

An adverse incident, as defined in the Appendix A of the permit, is an unusual or 

unexpected incident that an Operator has observed upon inspection or of which the 

Operator otherwise became 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. See Appendix A of 

the permit, for the complete definition of adverse incident. 

Where multiple Operators are authorized for a discharge that results in an adverse 

incident, notification and reporting by any one of the Operators constitutes 

compliance for all of the Operators, provided a copy of the written report required in 

Part 6.4.2 of the permit is also provided to all of the other authorized Operators 

within 30 days of the reportable adverse incident. 

When to File the Adverse Incident Report 

Operators must a provide a written report of any reportable adverse incidents to the 

appropriate EPA Regional office and to the state lead agency for pesticide 

regulation within 30 days of the adverse incident pursuant to Part 6.4.1.1 of the 

permit. 

Where to File the 30-day Adverse Incident Report 

The Operator must immediately notify the appropriate EPA Incident Reporting 

Contact, as identified at www.epa.gov/npdes/pesticides of the adverse incident 

within 24 hours. The Operator(s) must provide a written report of the adverse 

incident to the appropriate EPA Regional office at the address listed in Part 8 of the 

permit and to the state lead agency for pesticide regulation (see 

http://npic.orst.edu/state1.htm). 

If an Operator becomes aware of an adverse incident affecting a federally listed 

threatened or endangered species or its federally designated critical habitat which 

may have resulted from a discharge from the Operator’s pesticide application, the 

Operator must immediately notify the National Marine Fisheries Service (NMFS) in 

the case of an anadromous or marine species, or the United States Fish and Wildlife 

Service (FWS) in the case of a terrestrial or freshwater species.

Appendix I. Endangered Species Procedures

Assessing the Effects of Your Discharge and Discharge-Related Activities

You must meet at least one of the criteria in Part 1.1.2.4 of the permit to be eligible for 

coverage under this permit. You must follow the procedures in this appendix to certify eligibility 

to discharge to Waters of the United States containing NMFS Listed Resources of Concern, as 

defined in Appendix A of the permit, and determine under which of the eligibility criteria, if any, 

you qualify. NMFS Listed Resources of Concern for the PGP are provided at 

www.epa.gov/npdes/pesticides. When evaluating the potential effects of your activities, you 

must consider effects to NMFS Listed Resources of Concern within each treatment area 

identified in your NOI that contains such Resources. Discharges not meeting at least one of 

these criteria are not eligible for coverage under this permit. No discharges to Waters of the 

United States containing NMFS Listed Resources of Concern are eligible for coverage under the 

PGP unless those discharges are specifically identified and certified on a complete and accurate 

NOI form submitted to EPA. These discharges will be authorized 30 days after EPA posts the 

NOI on the Internet at www.epa.gov/npdes/pesticides, unless EPA notifies you otherwise within 

the 30-day period, or unless the discharges are in response to a Declared Pest Emergency 

Situation in which case the discharges are authorized immediately for a period of at least 60 days 

from the date this discharge began. 

Step One: Determine if NMFS Listed Resources of Concern are Present in the Treatment Area

 First, you should determine whether any discharges from your pesticide application 

activities in any treatment areas included under your NOI are likely to overlap directly with any 

NMFS Listed Resources of Concern, as identified at www.epa.gov/npdes/pesticides. The website 

provides maps and lists of Waters of the United States where the NMFS Listed Resources of 

Concern are present and contact information for regional NMFS offices in those areas. If you 

determine that any of your discharges are to Waters of the United States containing NMFS 

Listed Resources of Concern, you should proceed to Step Two. If you determine that no 

discharges from your pesticide application activities are to Waters of the United States 

containing NMFS Listed Resources of Concern, you can certify that the activity meets Criterion 

A (check box A on the NOI corresponding to Criterion A). In this case, you do not have to 

further consider any requirements related to Criteria B-F. Note that if you are not otherwise 

required to submit an NOI, you do not need to submit an NOI merely to document that you meet 

Criterion A. However, if you are required to submit an NOI anyway, you should document on 

the NOI that you meet Criterion A.

Step Two: Determine if a Previous ESA-Related Action has Already been Completed for your 

Activities

For each discharge to Waters of the United States containing NMFS Listed Resources of 

Concern, Decision-makers should determine whether they are eligible under either Criterion B or 

C because of a previously completed ESA Section 7 consultation, or a previously issued ESA 

Section 10 permit, respectively as follows:
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

I-2 

− The effects of your activities have been addressed in a consultation under ESA 

Section 7 on a separate Federal action and the consultation resulted in a concurrence 

by NMFS that the discharge was not likely to adversely affect listed species or critical 

habitat or NMFS concluded in a biological opinion that the discharge or discharges 

were not likely to jeopardize listed species or destroy or adversely modify critical 

habitat, either as part of your activities as planned or as modified with a reasonable 

and prudent alternative (check box B corresponding to Criterion B). For example, 

most federal agencies that apply pesticides have already consulted with NMFS, as 

required under 50 C.F.R. § 402.01(a), and can therefore certify under this criterion. 

− The effects of your activities have been addressed through approval of a Habitat 

Conservation Plan under Section 10 of the ESA (check box C corresponding to 

Criterion C). Your pesticide discharges may be authorized by this PGP if some 

activity is authorized through the issuance of a permit under section 10 of the ESA 

and that authorization addressed the effects of your pesticide discharges on federallylisted species and designated critical habitat. You must follow NMFS procedures 

when applying for an ESA Section 10 permit (see 50 CFR 222.22). Application 

instructions for section 10 permits for NMFS can be obtained by accessing the NMFS 

website (www.nmfs.noaa.gov) or by contacting the appropriate NMFS regional 

office.

 If you believe an existing ESA-related action may have already been completed for your 

planned pesticide application activities but you are uncertain of the details, you should contact 

your regional NMFS office (contact information available at www.epa.gov/npdes/pesticides). If 

an existing ESA-related action has not already been completed for your activities, proceed to 

Step Three.

Step Three: Determine if the Pesticide Application is in Response to a Declared Pest Emergency 

Situation 

Determine if all the discharges to Waters of the United States containing NMFS Listed 

Resources of Concern and that are to be included in the NOI are being performed in response to 

a Declared Pest Emergency Situation, as defined in Appendix A of the permit (check box D 

corresponding to Criterion D). In such a case, an NOI must be filed no later than 15 days after 

beginning to discharge with that NOI identifying: 

1. The location of the pest management area in detail or include a map of the location; 

2. Pest(s) to be controlled; 

3. Pesticide product(s) to be discharged and method of application; 

4. Planned quantity and rate of discharge(s) for each method of application; 

5. Number of planned discharges; 

6. Approximate date(s) of planned discharge(s); and 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

I-3 

7. The rational supporting the determination whether the discharge is likely to adversely 

affect NMFS Listed Resources of Concern, including the description of appropriate 

measures to be undertaken to avoid or eliminate the likelihood of adverse effects. 

Information provided for items 1 through 6 above must also include any discharges that have 

already occurred in the days (up to 15) prior to NOI submission. The discharge or discharges to 

address these Declared Pest Emergency Situations are authorized under the general permit for at 

least 60 days after beginning to discharge. You may continue to discharge after 60 days unless 

EPA advises the Operator that additional conditions or an individual permit are necessary. 

NMFS will, within 30 days of submission of the NOI, advise EPA whether the past and planned 

future discharges meet the eligibility criterion of not likely to adversely affect NMFS Listed 

Resources of Concern; whether the eligibility criterion could be met with additional conditions; 

or whether the eligibility criterion is not met. EPA will advise the Decision-maker within 15 

days after receiving notification from NMFS whether the discharge or discharges qualify for 

coverage beyond the 60-day authorization provided under the permit. If EPA identifies 

additional conditions to qualify discharges as eligible for coverage beyond 60 days under the 

permit, those conditions remain in effect for the life of the permit. EPA expects to rely on 

NMFS' determination in identifying eligibility for continuing authorization, either with or 

without additional conditions. If you do not hear from EPA within 45 days of submitting your 

NOI, you may assume that your authorization to discharge continues unless and until notified 

otherwise by EPA.

 If your pesticide application is not in response to a Declared Pest Emergency Situation, 

proceed to Step Four. 

Step Four: Determine if the Pesticide Application is not likely to adversely affect NMFS Listed 

Resources of Concern. 

 The PGP provides two options for Decision-makers to demonstrate that discharges from 

pesticide applications to Waters of the United States containing NMFS Listed Resources of 

Concern are not likely to adversely affect those resources for the activities for which the 

Decision-maker is seeking permit coverage. These options include: (1) obtaining confirmation 

from a NMFS Regional Office prior to NOI submission that discharges are not likely to 

adversely affect NMFS Listed Resources of Concern, or (2) self-certifying in the NOI that based 

on your analysis, you have concluded that discharges are not likely to adversely affect NMFS 

Listed Resources of Concern. Descriptions of procedures that are to be followed for these two 

options are described below. 

− Option 1 (Criterion E): For each treatment area that will include discharges to Waters of 

the United States containing NMFS Listed Resources of Concern, you may contact your 

Regional NMFS Office and request input regarding your planned discharges. If NMFS 

determines that your planned discharges are found to meet eligibility criteria for use (i.e., 

not likely to adversely affect NMFS Listed Resources of Concern), you have satisfied 

your eligibility obligations under Criterion E and you may submit your NOI for coverage 

under the PGP (check box E corresponding to Criterion E). As part of certifying your 

compliance with Criterion E, you must submit information received from NMFS 
United States Environmental Protection Agency 2011 NPDES Pesticides General Permit

I-4 

acknowledging the discharges that they have determined are not likely to adversely affect

NMFS Listed Resources of Concern and establishing any additional requirements for 

your permit eligibility. To maintain eligibility under the permit for those discharges, you 

must abide by those additional requirements for the duration of your coverage under the 

PGP.

− Option 2 (Criterion F): You must self-certify in your NOI that your discharge is not likely 

to adversely affect NMFS Listed Resources of Concern. To do so, you will have to take 

appropriate measures to avoid or eliminate the likelihood of adverse effects prior to 

applying for PGP coverage. These measures may be relatively simple, such as applying 

pesticides to waters at concentrations below those found to cause adverse effects, or 

during seasons when species of concern are not present Provided you are able to 

implement appropriate measures, you may proceed with submitting your NOI for 

coverage under the PGP (check box F corresponding to Criterion F). As part of certifying 

your compliance with Criterion F, you must submit information to support your findings, 

including: 

1. The location of the pest management area in detail or include a map of the location; 

2. Pest(s) to be controlled; 

3. Pesticide product(s) to be discharged and method of application; 

4. Planned quantity and rate of discharge(s) for each method of application; 

5. Number of planned discharges; 

6. Approximate date(s) of planned discharge(s); and 

7. The rational supporting the determination that the criterion for which the NOI is 

submitted is being met, including the description of appropriate measures to be 

undertaken to avoid or eliminate the likelihood of adverse effects. 

This information will be posted online and also will be sent to NMFS for their review. 

NMFS will, within 30 days of submission of the NOI, advise EPA whether it believes the 

planned discharges meet the eligibility criteria of not likely to adversely affect NMFS Listed 

Resources of Concern, whether the eligibility criterion could be met with additional conditions; 

or whether the eligibility criterion is not met. EPA will advise the Decision-maker as to whether 

the intended discharges qualify to proceed under the General Permit or whether an individual 

permit will be required. EPA expects to rely on NMFS' determination in identifying eligibility 

for authorization, either with or without additional conditions. If you do not hear from EPA 

within 30 days, you may assume that your discharge is authorized without further conditions. 

 You must comply with any terms and conditions imposed under the eligibility 

requirements to ensure that your pesticide discharges and discharge-related activities are 

protective of listed species and/or critical habitat. If the eligibility requirements cannot be met 

and maintained, then you are not eligible for coverage under this PGP. In these instances, you 

may consider applying to EPA for an individual permit, or revising your pesticide application 

activities so as to comply with these eligibility conditions and resubmitting an NOI to EPA that 

documents this revised eligibility.
