Secretary’s Order No. 2012-W-0006
 
Regulations Governing the Discharges from the Application of Pesticides to Waters of the State
 
AUTHORITY AND FINDINGS:
 
The Department of Natural Resources and Environmental Control (DNREC) is authorized, pursuant to 29 Del.C. §10119, to adopt emergency regulations if an agency determines that an imminent peril to human health, safety, or welfare requires adoption, amendment, or repeal of a regulation with less than the notice required by 29 Del.C. §10115. I hereby find that there is evidence of an imminent peril to human health, safety, and welfare that requires adoption of these emergency regulations.
The proposed regulatory revision of Section 9.0, Del.C., Chapter 60, General Permit Program, to add Subsection 9.8, Regulations Governing the Discharges from the Application of Pesticides to Waters of the State, is being promulgated as a result of the 2009 decision by the Sixth Circuit Court of Appeals (Court) that the application of biological pesticides and chemical pesticides with residuals to waters regulated under the provisions of the federal Clean Water Act must be regulated by a National Pollutant Discharge Elimination Program (NPDES) permit.
In 2009, the Court [National Cotton Council, et al. v. Environmental Protection Agency (EPA)] vacated EPA’s 2006 Final Rule on Aquatic Pesticides, which determined that NPDES permits were not required for applications of pesticides to U.S. waters. As a result of the court's decision, discharges to waters of the U.S. from the application of pesticides will require NPDES permits when the court's mandate takes effect. On March 28, 2011, the Court granted EPA’s request for an extension to allow more time for pesticide operators to obtain permits for pesticide discharges into U.S. waters from April 9, 2011, to October 31, 2011.
The State of Delaware has delegated authority from EPA for administration of the NPDES and issuance of the State’s own NPDES permits. Delaware must, therefore, promulgate regulations to address the new NPDES permitting requirement for the application of pesticides on or near water bodies of the state.
The DNREC Division of Water (DW) has been working to draft regulations to address the new NPDES permitting requirements. However, the required court date of October 31, 2011, was not met by Delaware due to the time-intensive nature of the undertaking combined with staff shortages/turnover in addition to EPA’s final rule not having been completed prior to the October 31 deadline. Therefore, DNREC currently is in violation of the federal requirements to have an NPDES program in place for the application of aquatic pesticides in or near Delaware waters.
The emergency Regulations Governing the Discharges from the Application of Pesticides to Waters of the State will allow pesticide applicators to obtain the required NPDES permits for applying aquatic pesticides from March–September 2012. Much of the aquatic pesticide spraying during this timeframe is concentrated on eliminating mosquito populations, which are a significant risk to human health and welfare due to their ability to transmit diseases and other blood-borne vectors.
The best known mosquito-borne diseases are West Nile Virus, Malaria, and Yellow Fever. Others, such as Dengue Fever and Encephalitides, are common within America but not as well-known throughout the general populous. Historically, mosquito-borne diseases have been at very low levels as the result of our nation’s progressive and intensive mosquito-control effort; however, for the first time in nearly 50 years, endemic cases of Dengue Fever and Malaria have been documented in the United States, mostly as a direct result of the declining vector control programs combined with an increase in immigrants who transport such blood-borne diseases into the U.S. (http://www.mda.state.md.us/plants-pests/mosquito_control/mosquito_info/mosquitoes_disease/index.php; and http://www.cdc.gov/ncidod/dvbid/westnile/index.htm).
For this reason, it is vital to promulgate such emergency regulations within Delaware to not allow the lapse in Delaware’s Mosquito Control Program offered through DNREC’s Division of Fish and Wildlife. The DNREC’s DW will continue to work with stakeholders toward completion of the full regulations through the normal regulatory process with a target promulgation of September 2012. Additionally, pursuant to 29 Del.C. §10119(4), DW will receive, consider, and respond to petitions by any interested person(s) for the reconsideration or revision of this emergency order.
 
EFFECTIVE DATE OF ORDER
 
This emergency order shall take upon promulgation in the Delaware Register and shall remain in effect for 90 days from date of publication or until regulations are implemented that eliminate the need for the emergency order.
 
ORDER
 
It is hereby ordered that the above-referenced emergency regulation is adopted pursuant to 29 Del.C. §10119.
 
Collin P. O’Mara, Secretary

Action Threshold means the point at which pest populations or environmental conditions cannot be tolerated necessitating that pest control action be taken based on economic, human health, aesthetic, or other effects. An action threshold may be based on current and/or past environmental factors that are or have been demonstrated to be conducive to pest emergence and/or growth, as well as past and/or current pest presence. Action thresholds are those conditions that indicate both the need for control actions and the proper timing of such actions.
Active Ingredientmeans 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, either direct as a result of pesticide residue or indirect. The phrase toxic or adverse effects includes effects that occur within Waters of the State 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), 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; or 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 State that are temporally and spatially related to exposure to a pesticide residue (e.g., vomiting, lethargy).
Best Available Technology (BAT)means a level of technology based on the very best (state of the art) controls and/or treatment measures that have been developed or are capable of being developed and that are economically achievable.
Best Management Practices (BMPs)means schedules of activities, prohibition of practices, maintenance procedures, and other management practices or measures to prevent or reduce the discharge of pollutants. BMPs include the following, among other practices and measures: structural and non-structural controls; treatment requirements; and operating procedures and practices to control site runoff, or spillage, or leaks, or drainage from raw materials storage.
Biological Control Agents means those agents that 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) includes microbial pesticides, biochemical pesticides and plant-incorporated protectants (PIP).
Microbial pesticide means a microbial agent intended for preventing, destroying, repelling, or mitigating any pest, or intended for use as a plant regulator, defoliant, or desiccant, that:
(1) Is a eukaryotic microorganism including, but not limited to, protozoa, algae, and fungi;
(2) Is a prokaryotic microorganism, including, but not limited to, Eubacteria and Archaebacteria; or,
(3) is a parasitically replicating microscopic element, including but not limited to, viruses. [40 CFR 158.2100(b)]
(1) Biochemical pesticide means a pesticide that:
Is a naturally-occurring substance or structurally-similar and functionally identical to a naturally-occurring substance;
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
Has a non-toxic mode of action to the target pest(s). [40 CFR 158.2000(a)(1)]
Plant-incorporated protectant 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 production of such a pesticidal substance. It also includes any inert ingredient contained in the plant, or produce thereof.
Chemical Pesticidesmeans all pesticides not otherwise classified as biological pesticides.
Cultural Methods means manipulation of the habitat to increase pest mortality by making the habitat less suitable to the pest.
Declared Pest Emergencymeans 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 endangered species, threatened species, beneficial organisms, or the environment.
Departmentmeans the State of Delaware Department of Natural Resources and Environmental Control.
Dischargewhen used without qualification, means the "discharge of a pollutant.”
Discharge of a Pollutantmeans the addition of any pollutant, or combination of pollutants, to state waters or the contiguous zone, or the ocean, from any source or activity other than a vessel or other floating craft when being used as a means of transportation and in compliance with Section 312 of the Act. This definition includes additions of pollutants into State waters from: Surface runoff that is collected or channeled by man; discharges through pipes, sewers, or other conveyances which do not lead to a treatment works; and discharges through pipes, sewers, or other conveyances, leading into a treatment works other than a publicly owned treatment works (POTW).

Impaired Water(or “Water Quality Impaired Water” or “Water Quality Limited Segment”) means a water is impaired for purposes of this Subsection 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 water quality standards (these waters are called “water quality limited segments” under 40 CFR 130.2(j)). Impaired waters include both waters with approved or established TMDLs, and those for which a TMDL has not yet been approved or established.
Inert Ingredientmeans 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. 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, provided that genetic material is intentionally introduced into a living plant in addition to the active ingredient.
Integrated Pest Managementmeans an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM uses current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.
Large Entitymeans any:

Pest Management Area means the area of land, including any water, for which an Operator has responsibility for and is authorized to conduct pest management activities as covered by this Subsection (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” means any practice used to meet the effluent limitations that comply with manufacturer specifications as required under FIFRA, 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 State.
Pesticide means:
(1) any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest,
(2) any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant; and,
(3) any nitrogen stabilizer, except that the term ‘‘pesticide’’ shall not include any article that is a “new animal drug” within the meaning of section 201(w) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 321(w)), that has been determined by the 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).
The term “pesticide” is used when referring to the “pesticide, as applied.” When referring to the chemical in the pesticide product with pesticidal qualities, the term “active ingredient” is used.
Pesticide Product means 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 Developmentmeans 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 Residueincludes 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.
Pesticide Use Patternmeans the method and type of pest that is controlled, and includes the following: mosquito and other flying insect control (adulticide and larvaecide); weed and algae control; animal pest control; and forest canopy pest control.
Point Sourcemeans 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.
Pollutantmeans 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.”
Secretarymeans the Secretary of the State of Delaware Department of Natural Resources and Environmental Control or his duly authorized designee.
Statemeans the State of Delaware.
Target Pest means the organism(s) toward which pest management measures are being directed.
Tier 3 Watersmeans for anti-degradation 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)means the amount of a given pollutant that may be discharged to a waterbody from point, nonpoint and natural background sources and still allow attainment or maintenance of the applicable narrative and numerical water quality standards. A "TMDL" is the sum of the individual wasteload allocations or WLAs for point sources and load allocations or LAs for nonpoint sources of pollution and natural background. A “TMDL” may include a reasonable margin of safety (MOS) to account for uncertainties regarding the relationship between mass loading and resulting water quality. In simplistic terms, a "TMDL" attempts to match the strength, location and timing of pollution sources within a watershed with the inherent ability of the receiving water to assimilate the pollutant without adverse impact.
Treatment Areameans the entire area, whether over land or water, where a pesticide application is intended to provide pest control 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 pest control benefits.
Upset means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based 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.
Waters of the State” or “State Watersmeans all water, on the surface and under the ground, wholly or partially within, or bordering the State, or within its jurisdiction including but not limited to:
(1) waters which are subject to the ebb and flow of the tide including, but not limited to, estuaries, bays and the Atlantic Ocean;
(2) all interstate waters, including interstate wetlands;
(3) all other Waters of the State, such as lakes, rivers, streams (including intermittent and ephemeral streams), drainage ditches, tax ditches, creeks, mudflats, sand flats, wetlands, sloughs, or natural or impounded ponds;
(4) all impoundments of waters otherwise defined as Waters of the State under this definition;
(5) wetlands adjacent to waters (other than waters that are themselves wetlands) identified in the above four statements; and,
(6) Although waste and stormwater treatment systems or waste storage structures including, but not limited to, treatment ponds or lagoons designed to meet the requirements of the Clean Water Act (other than cooling ponds which otherwise meet the requirements of this definition) are not considered to be “Waters of the State”, coverage will be required if determined to discharge into Waters of the State.
Water Quality ImpairedSee ‘Impaired Water’.
Water Quality Standardsmeans any rule or limit established by the Secretary which consists of a designated use or uses for Waters of the State and the water quality criteria for such waters based upon such designated uses.
Wetlands means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas. Wetland areas are as delineated under and through 7 Del.C. Ch. 66 and the "Corps of Engineers Wetlands Delineation Manual", dated January, 1987.

Ch. 60 and the federal Clean Water Act and may be subject to penalties.
9.8.7 Notice of Termination (NOT)
9.8.7.1 Coverage under this Subsection continues until a completed Notice of Termination (NOT) form has been submitted to the Department. The NOT shall be submitted on a form provided by the Department. Failure to submit a complete and accurate NOT form will result in the facility being denied termination under this Subsection.
9.8.7.2 All NOT submissions must follow Signatory Requirements as described in 9.8.14, and must be sent to the address as provided in 9.8.15.
9.8.7.3 The NOT Form shall be submitted within 30 days after one or more of the following conditions have been met:

9.8.7.3.3 Coverage under an individual permit has been granted by the Department.
9.8.8 Individual NPDES Permit Coverage
9.8.8.1 Requirements for Coverage under an Individual Permit
The Department may require the Operator to apply for and/or obtain authorization to discharge under an individual NPDES permit in accordance with Section 6.0 of the “Regulations Governing the Control of Water Pollution”. If the Department requires Operator to apply for an individual NPDES permit, the Department will notify the Operator in writing that a permit application is required. This notification will include a brief statement of the reasons for this decision and will provide application information. In addition, if the Operator’s discharges are authorized under this regulation, the notice will set a deadline to file the permit application, and will include a statement that on the effective date of the individual NPDES permit coverage under this regulation will terminate. The Department may grant additional time to submit the application if the Operator submits a request setting forth reasonable grounds for additional time. If the Operator is covered and fails to submit an individual NPDES permit application as required by the Department, then the applicability of this permit to the Operator is terminated at the end of the day specified by the Department as the deadline for application submittal. The Department may take enforcement action for any unpermitted discharge or violation of any permit requirement.
9.8.8.2 Request for Coverage under an Individual NPDES Permit
The Operator may apply for an individual permit. In such a case, the Operator must submit an individual permit application in accordance with the requirements of Section 6.0 of the “Regulations Governing the Control of Water Pollution”, with reasons supporting the request, to the Department. The request may be granted by issuance of an individual permit if the Operator’s reasons are warranted.
When an individual NPDES permit is issued to the Operator to discharge a pollutant to Waters of the State as a result of a pesticide application, the Operator’s authorization to discharge under this regulation is terminated on the effective date of the individual permit.
9.8.9 Operator’s Responsibilities (All Operators)
9.8.9.1 Requirement to Use Best Management Practices
Operators are required to comply with all other applicable federal or state laws and regulations that pertain to application of pesticides.
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 9.8.2, the Operator must use such pesticide consistent with any applicable research plan and experimental use permit.
To meet the requirements of this regulation, all Operators must implement 9.8.9.1 to minimize the discharge of pesticides to Waters of the State from the application of pesticides, through the use of Pest Management Measures, as defined in 9.8.2.
9.8.9.1.1 To the extent determined by the Operator, 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.
9.8.9.1.2 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.
9.8.9.1.3 Assess weather conditions (e.g. temperature, precipitation and wind speed) in the treatment area to ensure application is consistent with all applicable state and federal requirements.
9.8.9.1.4 Problem Identification for All Pest Management Options
Prior to the first pesticide application covered under this permit that will result in a discharge to Waters of the State, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, Operators that are required to have a PDMP as described in 9.8.10 must do the following for each pest management area, as defined in 9.8.2:
9.8.9.1.4.1 Mosquito and Other Flying Insect Pest Control (Adulticide and larvaecide)
Establish densities for larval and adult mosquito or flying insect pest populations or identify environmental condition(s), either current or based on historical data, to serve as action threshold(s) for implementing Pest Management Measures;
Identify target pest(s) to develop Pest Management Measures based on developmental and behavioral considerations for each pest;
Identify known breeding sites for source reduction, larval control program, and habitat management;
Analyze existing surveillance data to identify new or unidentified sources of mosquito or flying insect pest problems as well as sites that have recurring pest problems; and
In the event there are no data for the pest management area in the past calendar year, use other available data as appropriate to meet the conditions in 9.8.9.1.4.1.
9.8.9.1.4.2 Weed and Algae Pest Control
Identify areas with pest problems and characterize the extent of the problems, including, for example, water use goals not attained (e.g. wildlife habitat, fisheries, vegetation, and recreation);
Identify target pest(s);
Identify possible factors causing or contributing to the pest problem (e.g., nutrients, invasive species, etc.);
Establish any pest-and site-specific action threshold, as defined in 9.8.2, for implementing 9.8.9.2; and
In the event there are no data for the pest management area in the past calendar year, use other available data as appropriate to meet the permit conditions in 9.8.9.1.4.2.
9.8.9.1.4.3 Animal Pest Control
Identify areas with pest problems and characterize the extent of the problems, including, for example, water use goals not attained (e.g. wildlife habitat, fisheries, vegetation, and recreation);
Identify target pest(s);
Identify possible factors causing or contributing to the problem (e.g., nutrients, invasive species);
Establish any pest-and site-specific action threshold, as defined in 9.8.2 for implementing 9.8.9.2; and
In the event there are no data for the pest management area in the past calendar year, use other available data as appropriate to meet the permit conditions in 9.8.9.1.4.3.
9.8.9.1.4.4 Forest Canopy Pest Control
Establish any pest-and site-specific action threshold, as defined in 9.8.2, for implementing 9.8.9.2;
Identify target pest(s) to develop Pest Management Measures based on developmental and behavioral considerations for each pest;
Identify current distribution of the target pest and assess potential distribution in the absence of Pest Management Measures; and
In the event there are no data for the pest management area in the past calendar year, use other available data as appropriate to meet the permit conditions in 9.8.9.1.4.4.
9.8.9.2 Utilization of Best Available Technology for All Pest Management Options
Prior to the first pesticide application covered under this Subsection that will result in a discharge to Waters of the State and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, Operators must select and implement efficient and effective means of Pest Management Measures that minimize discharges resulting from the application of pesticides to control mosquitoes or other flying insect pests, weed and algae pests, animal pests, and forest canopy pests. In developing the Pest Management Measures for each pest management area, the Operator must evaluate the following management options, including a combination of these management options, considering impact to water quality, impact to non-target organisms, feasibility, and cost effectiveness:
9.8.9.2.1 No action
9.8.9.2.2 Prevention
9.8.9.2.3 Mechanical or physical methods
9.8.9.2.4 Cultural methods
9.8.9.2.5 Biological control agents
9.8.9.2.6 Pesticides
If a pesticide is selected to manage pests and application of the pesticide will result in a discharge to a Waters of the State, Operators must:
Conduct surveillance in an area that is representative of the pest problem prior to each pesticide application to assess the pest management area and to determine when the action threshold(s) is met. Surveillance may include larval and/or adult life stages, or evaluation of existing larval surveillance data, environmental conditions, or data from adjacent areas; and
Reduce the impact on the environment and on non-target organisms by applying the pesticide only when the action threshold(s) has been met; and
In situations or locations where practicable and feasible for efficacious control, use larvicides as a preferred pesticide for mosquito or flying insect pest control when the larval action threshold(s) has been met; and
In situations or locations where larvicide use is not practicable or feasible for efficacious control, use adulticides for mosquito or flying insect pest control when the adult action threshold(s) has been met; and
Evaluate using pesticides against the most susceptible developmental stage.
9.8.9.3 Visual Monitoring Requirements
During any pesticide application with discharges authorized under this permit, all Operators must, when considerations for safety and feasibility allow, visually assess the area to and around where pesticides are applied for possible and observable adverse incidents, as defined in 9.8.2, caused by application of pesticides, including the unanticipated death or distress of non-target organisms and disruption of wildlife habitat, recreational or municipal water use.
9.8.9.4 Observational Monitoring Requirements
9.8.9.4.1 The amount of pesticide applied shall be monitored to ensure that the lowest effective amount is used to control the pest, consistent with reducing the potential for development of pest resistance without exceeding the maximum allowable rate of the product label.
9.8.9.4.2 Pesticide application activities shall be monitored to ensure that regular maintenance activities are being performed and that application equipment is in proper operating condition to reduce the potential for leaks, spills, or other unintended discharge of pesticides to surface waters.
9.8.9.4.3 Pesticide application activities shall also be monitored to ensure that the application equipment is in proper operating condition by adhering to any manufacturer's conditions and industry practices and by calibrating, cleaning, and repairing equipment on a regular basis.
9.8.9.5 Water Quality-Based Effluent Limitations and Monitoring
Although no numeric water-quality based effluent limits are established under this Subsection, all Operators must control discharges as necessary to meet applicable numeric and narrative state water quality standards, for any discharges authorized under this Subsection, with compliance required upon beginning such discharge.
If at any time an Operator becomes aware or the Department determines that the Operator’s discharge causes or contributes to an excursion of any applicable water quality standard, the Operator must take corrective action as required in 9.8.11 up to and including the ceasing of the discharge, if necessary, and the Department can require water quality-based monitoring by the Operator deemed to be necessary at any time. In this circumstance, test procedures shall be approved under 40 CFR Part 136. Calculations for all limitations that require averaging of measurements must use an arithmetic mean unless otherwise specified by the Department.
9.8.10 Pesticide Discharge Management Plan (PDMP) Requirements
9.8.10.1 PDMP development applies to any one of the following:
9.8.10.1.1 Any Operator (including municipalities) that qualify as a Large Entity, as defined in 9.8.2; or,

9.8.11 Corrective Action
All Operators must comply with the provisions of 9.8.11 for any authorized discharges, with compliance required upon beginning such discharge.
9.8.11.1 Situations Requiring Revision of Control Measures
Operators must review and, as necessary, revise the evaluation and selection of Pest Management Measures, Best Management Practices, and utilization of Best Available Technology as described in 9.8.9.1 and 9.8.9.2 for the following situations:
9.8.11.1.1 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.
9.8.11.1.2 Operators become aware, or the Department concludes, that Pest Management Measures are not adequate/sufficient for the discharge to meet applicable water quality standards.
9.8.11.1.3 Any monitoring activities indicate failure to meet applicable technology-based non-numeric effluent limitations in 9.8.9.5.
9.8.11.1.4 An inspection or evaluation of activities by an EPA official or the Department reveals that modifications are necessary to meet the non-numeric effluent limitations in this permit.
9.8.11.1.5 Any Operator observes or is otherwise made aware of an adverse incident as defined in 9.8.2.
9.8.11.2 Corrective Action Deadlines
If an Operator determines that changes to Pest Management Measures, Best Management Practices, and Utilization of Best Available Technology as in 9.8.9.1 and 9.8.9.2 are necessary to eliminate any situation identified, such changes must be made before or, if not practicable, as soon as possible after the next pesticide application that results in a discharge.
9.8.11.3 Effect of Corrective Action
The occurrence of a situation identified in 9.8.11.1 may constitute a violation of this Subsection. Correcting the situation according to 9.8.11.1 does not absolve the Operator of liability for any original violation. However, failure to comply with 9.8.11.1 constitutes an additional violation. The Department will consider the appropriateness and promptness of corrective action in determining enforcement responses to permit violations.
The Department or a court 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 Subsection. Those requirements and schedules will supersede those of 9.8.11.1 if such requirements conflict.
