Summary:

The proposed regulation develops and issues a Virginia Pollutant Discharge Elimination System (VPDES) general permit for discharges from pesticides applied directly to surface waters to control pests, or applied to control pests that are present in or over, including near, surface waters. The general permit regulation is needed to comply with court-ordered requirements for the federal Environmental Protection Agency (EPA) and states to issue national pollutant discharge elimination system (NPDES) permits for both chemical pesticide applications that leave a residue or excess in water and all biological pesticide applications that are made in or over, including near, waters of the United States.

Since the court ruling, EPA collected and analyzed data on pesticide applications, including labeling requirements, pesticide uses, best management practices employed to minimize the impact of pesticides on water quality, and existing state water quality standards for pesticides. EPA proposed a NPDES pesticides general permit, issued by EPA, for areas where EPA remains the NPDES permitting authority and for Virginia and other delegated NPDES states to use in drafting their permit.

The following pesticide uses will be covered under the general permit per the court order for operators that apply pesticides in or near water: (i) mosquito and other flying insect pest control, (ii) aquatic weed and algae control, (iii) aquatic animal pest control, and (iv) forest canopy pest control.

The proposed regulation generally follows EPA's proposed pesticide general permit with (i) definitions, (ii) eligibility requirements (authorizations to discharge), (iii) technology effluent limitations (integrated pest management considerations), (iv) water quality based limitations, (v) monitoring requirements, (vi) pesticide discharge monitoring plan, (vii) corrective actions, (viii) adverse incident and spills and leaks reporting, (ix) recordkeeping and annual reporting requirements, and (x) conditions applicable to all permits. However, the EPA proposed general permit was adjusted for Virginia users for clarification, flexibility, and ease of implementation. No regulation currently exists for this permit.

CHAPTER 800
VIRGINIA POLLUTANT DISCHARGE ELIMINATION SYSTEM (VPDES) GENERAL PERMIT FOR DISCHARGES RESULTING FROM THE APPLICATION OF PESTICIDES TO SURFACE WATERS

9VAC25-800-10. Definitions.

The words and terms used in this chapter shall have the same meanings as given in the State Water Control Law (§ 62.1-44.2 et seq. of the Code of Virginia) and the VPDES Permit Regulation (9VAC25-31), unless the context clearly indicates otherwise, except that for the purposes of this chapter:

"Action threshold" means the point at which pest populations or environmental conditions can no longer be tolerated necessitating that pest control action be taken based on economic, human health, aesthetic, or other effects. Sighting a single pest does not always mean control is needed. Action thresholds help determine both the need for control actions and the proper timing of such actions. Action thresholds are site specific and part of integrated pest management decisions.

"Active ingredient" means any substance (or group of structurally similar substances if specified by the federal Environmental Protection Agency (EPA) that will prevent, destroy, repel, or mitigate any pest, or that functions as a plant regulator, desiccant, or defoliant within the meaning of § 2 (a) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) (7 USC § 136 et seq.). 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.

"Adverse incident" means an incident that the operator observes upon inspection or of which otherwise becomes aware, in which there is evidence that:

1. A person or nontarget organism has likely been exposed to a pesticide residue; and

2. The person or nontarget organism suffered a toxic or adverse effect.

The phrase "toxic or adverse effects" includes effects that occur within surface waters on nontarget plants, fish, or wildlife that are unusual or unexpected as a result of exposure to a pesticide residue and may include any of the following:

1. Distressed or dead juvenile and small fishes;

2. Washed up or floating fish;

3. Fish swimming abnormally or erratically;

4. Fish lying lethargically at water surface or in shallow water;

5. Fish that are listless or nonresponsive to disturbance;

6. Stunting, wilting, or desiccation of nontarget submerged or emergent aquatic plants; and

7. Other dead or visibly distressed nontarget aquatic or semi-aquatic organisms (amphibians, turtles, invertebrates, etc.).

The phrase "toxic or adverse effects" also includes any adverse effects to humans (e.g., skin rashes), domesticated animals or wildlife (e.g., vomiting, lethargy) that occur either directly or indirectly from a discharge to surface waters that are temporally and spatially related to exposure to a pesticide residue.

"Best management practices" or "BMPs" means, for purposes of this chapter, schedules of activities, prohibitions of practices, maintenance procedures, preventative practices (pre-emergent applications) and other management practices to prevent or reduce the pollution of surface waters. BMPs also include treatment requirements, operating procedures, and practices to control site runoff, spillage, or leaks.

"Biological control" means organisms that can be introduced to sites, such as herbivores, predators, parasites, and hyperparasites.

"Biological pesticides" or "biopesticides" include microbial pesticides, biochemical pesticides, and plant-incorporated protectants (PIP).

1. "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:

a. Is a eucaryotic microorganism, including but not limited to protozoa, algae, and fungi;

b. Is a procaryotic microorganism, including but not limited to Eubacteria and Archaebacteria; or

c. Is a parasitically replicating microscopic element, including but not limited to viruses.

2. "Biochemical pesticide" means a pesticide that:

a. Is a naturally occurring substance or structurally similar and functionally identical to a naturally occurring substance;

b. Has a history of exposure to humans and the environment demonstrating minimal toxicity, or in the case of a synthetically derived biochemical pesticide, is equivalent to a naturally occurring substance that has such a history; and

c. Has a nontoxic mode of action to the target pest(s).

3. "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 pesticides" means all pesticides not otherwise classified as biological pesticides.

"Control measure" means any best management practice (BMP) or other method used to meet the effluent limitations in this permit. Control measures must comply with label directions and relevant legal requirements. Additionally, control measures could include other actions, including nonchemical tactics (e.g., cultural methods), that a prudent operator would implement to reduce or eliminate discharges resulting from pesticide application to surface waters to comply with the effluent limitations in this permit.

"Cultural methods" means manipulation of the habitat to increase pest mortality by making the habitat less suitable to the pest.

"Declared pest emergency situation" means 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 10 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:

a. Endangered species;

b. Threatened species;

c. Beneficial organisms; or

d. The environment.

"DEQ" or "department" means the Virginia Department of Environmental Quality.

"Discharge of a pollutant" means, for purposes of this chapter, any addition of any "pollutant" or combination of pollutants to surface waters 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.

"FIFRA" means the Federal Insecticide, Fungicide and Rodenticide Act (7 USC § 136 et seq.) as amended.

"Impaired water" or "water quality impaired water" or "water quality limited segment" means any stream segment where the water quality does not or will not meet applicable water quality standards, even after the application of technology-based effluent limitations required by §§ 301(b) and 306 of the Clean Water Act (CWA) (33 USC § 1251 et seq. as of 1987). Impaired waters include both impaired waters with approved or established TMDLs, and impaired waters for which a TMDL has not yet been approved or established.

"Inert ingredient" means any substance (or group of structurally similar substances if designated by EPA), 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 management" or "IPM" means 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.

"Label" means the written, printed, or graphic matter on, or attached to, the pesticide or device, or the immediate container thereof, and the outside container or wrapper of the retail package, if any, of the pesticide or device.

"Labeling" means all labels and other written, printed, or graphic matter:

1. Upon the pesticide or device or any of its containers or wrappers;

2. Accompanying the pesticide or device at any time; or

3. To which reference is made on the label or in literature accompanying the pesticide or device, except when accurate, nonmisleading reference is made to current official publications of the agricultural experiment station, the Virginia Polytechnic Institute and State University, the Virginia Department of Agriculture and Consumer Services, the State Board of Health, or similar federal institutions or other official agencies of the Commonwealth or other states when such states are authorized by law to conduct research in the field of pesticides.

"Mechanical/physical methods" means mechanical tools or physical alterations of the environment, for pest prevention or removal.

"Minimize" means to reduce or eliminate pesticide discharges to surface waters through the use of control measures to the extent technologically available and economically practicable and achievable.

"Nontarget organisms" means any organisms that are not the target of the pesticide.

"Operator" means, for purposes of this chapter, any person involved in the application of a pesticide that results in a discharge to state waters that meets either or both of the following two criteria:

1. The person has control over the financing for or the decision to perform pesticide applications that result in discharges, including the ability to modify those decisions; or

2. The person has day-to-day control of or performs activities that are necessary to ensure compliance with the permit (e.g., they are authorized to direct workers to carry out activities required by the permit or perform such activities themselves).

"Person" means, for purposes of this chapter, an individual; a corporation; a partnership; an association; a local, state, or federal governmental body; a municipal corporation; or any other legal entity.

"Pest" means any deleterious organism that is:

1. Any vertebrate animal other than man;

2. Any invertebrate animal excluding any internal parasite of living man or other living animals;

3. Any plant growing where not wanted, and any plant part such as a root; or

Any bacterium, virus, or other microorganisms (except for those on or in living man or other living animals and those on or in processed food or processed animal feed, beverages, drugs as defined by the federal Food, Drug, and Cosmetic Act at 21 USC § 321(g)(1), and cosmetics as defined by the federal Food, Drug, and Cosmetic Act at 21 USC § 321(i)).

Any organism classified as endangered, threatened, or otherwise protected under federal or state laws shall not be deemed a pest for the purposes of this chapter.

"Pest management area" means the area of land, including any water, for which pest management activities covered by this permit are conducted.

"Pesticide" means:

1. Any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any insects, rodents, fungi, bacteria, weeds, or other forms of plant or animal life or viruses, except viruses on or in living man or other animals, which the Commissioner of Agriculture and Consumer Services shall declare to be a pest;

2. Any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant; and

3. Any substance which is intended to become an active ingredient thereof.

Pesticides that are used or applied shall only be those that are approved and registered for use by the Virginia Department of Agriculture and Consumer Services.

"Pesticide product" means a pesticide in the particular form (including active and inert ingredients, 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" means activities undertaken on a systematic basis to gain new knowledge (research) or the application of research findings or other scientific knowledge for the creation of new or significantly improved products or processes (experimental development). These types of activities are generally categorized under 5417 under the 2007 North American Industry Classification System (NAICS).

"Pesticide residue" includes that portion of a pesticide application that has been discharged from a point source to surface waters and no longer provides pesticidal benefits. It also includes any degradates of the pesticide.

"Point source" means, for purposes of this chapter, any discernible, confined, and discrete conveyance including, but not limited to, any pipe, ditch, channel, tunnel, conduit, or container from which pollutants are or may be discharged. This includes biological pesticides or pesticide residuals coming from a container or nozzle of a pesticide application device. This term does not include return flows from irrigated agriculture or agricultural storm water run-off.

"Pollutant" means, for purposes of this chapter, biological pesticides and any pesticide residue resulting from use of a chemical pesticide.

2. All interstate waters, including interstate wetlands;

3. 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:

a. That are or could be used by interstate or foreign travelers for recreational or other purposes;

b. From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or

c. That are used or could be used for industrial purposes by industries in interstate commerce.

4. All impoundments of waters otherwise defined as surface waters under this definition;

5. Tributaries of waters identified in subdivisions 1 through 4 of this definition;

6. The territorial sea; and

7. Wetlands adjacent to waters, other than waters that are themselves wetlands, identified in subdivisions 1 through 6 of this definition.

Surface waters do not include waste treatment systems, including treatment ponds or lagoons designed to meet the requirements of the Clean Water Act (CWA) and the law. Surface waters do not include prior converted cropland. Notwithstanding the determination of an area's status as prior converted cropland by any other agency, for the purposes of the CWA, the final authority regarding the CWA jurisdiction remains with the EPA.

"Target pest" means the organism toward which pest control measures are being directed.

"Total maximum daily load" or "TMDL" means a calculation of the maximum amount of a pollutant that a waterbody 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, and load allocations (LAs) for nonpoint sources or natural background or both, and must include a margin of safety (MOS) and account for seasonal variations.

"Treatment area" means the area of land including any waters, or the linear distance along water's edge, to which pesticides are being applied. Multiple treatment areas may be located within a single pest management area.

Treatment area includes the entire area, whether over land or water, where the pesticide application is intended to provide pesticidal benefits. 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 should be calculated by multiplying the width of the canal by the length over which the pesticide is intended to control weeds. The treatment area for a lake or marine area is the water surface area where the application is intended to provide pesticidal benefits.

Treatment area calculations for pesticide applications that occur at water's edge, where the discharge of pesticides directly to waters is unavoidable, are determined by the linear distance over which pesticides are applied. For example, treating both sides of a five-mile-long river, stream, or ditch is equal to 10 miles of treatment area. Treating five miles of shoreline or coast would equal a five-mile treatment area.

"VDACS" means the Virginia Department of Agriculture and Consumer Services.

"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.

9VAC25-800-20. Purpose; delegation of authority; effective date of permit.

A. This general permit regulation governs discharges resulting from the application of pesticides to surface waters.

B. The Director of the Department of Environmental Quality, or his designee, may perform any act of the board provided under this chapter, except as limited by § 62.1-44.14 of the Code of Virginia.

C. This general VPDES permit will become effective on April 10, 2011, and expire on June 30, 2013.

9VAC25-800-30. Authorization to discharge.

A. Any operator that meets the eligibility requirements in subsection B of this section is hereby authorized for his discharges resulting from the application of pesticides to surface waters of the Commonwealth of Virginia.

The definition of operator in 9VAC25-800-10 provides that more than one person may be responsible for the same discharge resulting from pesticide application. Any operator authorized to discharge under this general permit is responsible for compliance with the terms of this permit for discharges resulting from the application of pesticides.

B. Eligibility. This permit is available to operators who discharge to surface waters from the application of (i) biological pesticides, or (ii) chemical pesticides that leave a residue (hereinafter collectively "pesticides"), when the pesticide application is for one of the following pesticide use patterns:

1. Mosquito and other flying insect pest control - to control public health/nuisance and other flying insect pests that develop or are present during a portion of their life cycle in or above standing or flowing water. Public health/nuisance and other flying insect pests in this use category include, but are not limited to, mosquitoes and black flies.

2. Aquatic weed and algae control - to control invasive or other aquatic (emergent, floating or submerged) nuisance weeds and algae in surface waters. Aquatic nuisance weeds include, but are not limited to, cattails, hydrilla, and watermeal.

3. Aquatic animal pest control - to control aquatic invasive or other aquatic animal pests in surface waters. Aquatic animal pests in this use category include, but are not limited to, fish (e.g., snakehead) and zebra mussels.

4. Forest canopy pest control - aerial application of a pesticide over 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 surface water.

C. Operators applying pesticides are required to maintain a pesticide discharge management plan (PDMP) if they exceed the annual treatment area thresholds in Table 1 of this subsection:

Table 1. Annual Treatment Area Thresholds
Pesticide Use	Annual Threshold
Mosquitoes and Other Flying Insect Pests	640 acres of treatment area
Aquatic Weed and Algae Control:
- In Water	20 acres of treatment area1
- At Water's Edge	20 linear miles of treatment area at water's edge2
Aquatic Animal Pest Control:
- In Water	20 acres of treatment area1
- At Water's Edge	20 linear miles of treatment area at water's edge2
Forest Canopy Pest Control	640 acres of treatment area
1 Calculations include the area of the applications made to: (i) surface waters and (ii) conveyances with a hydrologic surface connection to surface waters 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 10 acre site is counted as 20 acres of treatment area.
2 Calculation include the linear extent of the application made along the water's edge adjacent to: (i) surface waters and (ii) conveyances with a hydrologic surface connection to surface waters 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 10 mile ditch is equal to 20 miles of water treatment area.

D. An operator's discharge resulting from the application of pesticides is not authorized under this permit in the event of any of the following:

1. The operator is required to obtain an individual VPDES permit in accordance with 9VAC25-31-170 B 3 of the VPDES Permit Regulation.

2. The discharge would violate the antidegradation policy stated in 9VAC25-260-30 of the Virginia Water Quality Standards. Discharges resulting from the application of pesticides are temporary and allowable in exceptional waters (see 9VAC25-260-30 A 3 (b) (3)).

3. The operator is proposing a discharge from a pesticide application to surface waters that have been identified as impaired by that pesticide or its degradates. Impaired waters include both impaired waters with board-adopted, EPA-approved or EPA-imposed TMDLs, and impaired waters for which a TMDL has not yet been approved, established, or imposed.

If the proposed discharge would not be eligible for coverage under this permit because the surface water is listed as impaired for that specific pesticide, but the applicant has evidence that shows the water is no longer impaired, the applicant may submit this information to the board and request that coverage be allowed under this permit.

E. Discharge authorization date. Operators are not required to submit a registration statement and are authorized to discharge under this permit immediately upon the permit's effective date of April 10, 2011.

F. Compliance with this general permit constitutes compliance with the Clean Water Act, the State Water Control Law, and applicable regulations under either, with the exceptions stated in 9VAC25-31-60 of the VPDES Permit Regulation. Approval for coverage under this general VPDES permit does not relieve any operator of the responsibility to comply with any other applicable federal, state, or local statute, ordinance, or regulation. For example, this permit does not negate the requirements under FIFRA and its implementing regulations to use registered pesticides consistent with the product's labeling.

G. Continuation of permit coverage.

1. This general permit shall expire on June 30, 2013, except that the conditions of the expired pesticides general permit will continue in force for an operator until coverage is granted under a reissued pesticides general permit if the board, through no fault of the operator, does not reissue a pesticides general permit on or before the expiration date of the expiring general permit.

2. General permit coverages continued under this section remain fully effective and enforceable.

3. When the operator that was covered under the expiring or expired pesticides general permit is not in compliance with the conditions of that permit, the board may choose to do any or all of the following:

a. Initiate enforcement action based upon the pesticides general permit that has been continued;

b. Issue a notice of intent to deny coverage under a reissued pesticides general permit. If the general permit coverage is denied, the operator would then be required to cease the activities authorized by the continued general permit or be subject to enforcement action for operating without a permit;

c. Issue an individual permit with appropriate conditions; or

d. Take other actions authorized by the VPDES Permit Regulation (9VAC25-31).

9VAC25-800-40. Registration statement.

Operators are not required to submit a registration statement to apply for coverage under this general VPDES permit for discharges resulting from the application of pesticides to surface waters.

9VAC25-800-50. Termination of permit coverage.

Operators are not required to submit a notice of termination to terminate permit coverage under this general VPDES permit for discharges resulting from the application of pesticides to surface waters.

9VAC25-800-60. General permit.

Any operator who is authorized to discharge shall comply with the requirements contained herein and be subject to all requirements of 9VAC25-31-170.

General Permit No.: VAGxx
Effective Date: April 10, 2011
Expiration Date: June 30, 2013

GENERAL PERMIT FOR DISCHARGES RESULTING FROM THE APPLICATION OF PESTICIDES TO SURFACE WATERS OF VIRGINIA

AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA POLLUTANT DISCHARGE ELIMINATION SYSTEM AND THE VIRGINIA STATE WATER CONTROL LAW

In compliance with the provisions of the Clean Water Act (33 USC § 1251 et seq.), as amended, and pursuant to the State Water Control Law and regulations adopted pursuant thereto, operators that apply pesticides that result in a discharge to surface waters are authorized to discharge to surface waters within the boundaries of the Commonwealth of Virginia.

The authorized discharge shall be in accordance with this cover page, Part I-Effluent Limitations, Monitoring Requirements, and Special Conditions, and Part II-Conditions Applicable to All VPDES Permits, as set forth herein. Coverage under this general VPDES permit does not relieve any operator of the responsibility to comply with any other applicable federal, state, or local statute, ordinance, or regulation, including the pesticide product label.

Part I
Effluent Limitations, Monitoring Requirements, and Special Conditions

A. Effluent limitations.

1. Technology-based effluent limitations. To meet the effluent limitations in this permit, the operator shall implement site-specific control measures that minimize discharges of pesticides to surface waters.

a. Minimize pesticide discharges to surface waters. All operators shall minimize the discharge of pollutants resulting from the application of pesticides, and:

(1) Use the lowest effective amount of pesticide product per application and optimum frequency of pesticide applications necessary to control the target pest, consistent with reducing the potential for development of pest resistance without exceeding the maximum allowable rate of the product label;

(2) No person shall apply, dispense, or use any pesticide in or through any equipment or application apparatus unless the equipment or apparatus is in sound mechanical condition and capable of satisfactory operation. All pesticide application equipment shall be properly equipped to dispense the proper amount of material. All pesticide mixing, storage, or holding tanks, whether on application equipment or not, shall be leak proof. All spray distribution systems shall be leak proof, and any pumps that these systems may have shall be capable of operating at sufficient pressure to assure a uniform and adequate rate of pesticide application; and

(3) All pesticide application equipment shall be equipped with cut-off valves and discharge orifices to enable the operator to pass over non-target areas without contaminating them. All hoses, pumps, or other equipment used to fill pesticide handling, storage, or application equipment shall be fitted with an effective valve or device to prevent backflow into water supply systems, streams, lakes, other sources of water, or other materials. However, these backflow devices or valves are not required for separate water storage tanks used to fill pesticide application equipment by gravity systems when the fill spout, tube, or pipe is not allowed to contact or fall below the water level of the application equipment being filled, and no other possible means of establishing a back siphon or backflow exists.

b. Integrated pest management (IPM) practices. The operator shall implement integrated pest management practices to ensure that discharges resulting from the application of pesticides to surface waters are minimized. Operators that exceed the annual treatment area thresholds established in 9VAC25-800-30 C are also required to maintain a pesticide discharge management plan (PDMP) in accordance with Part 1 C of this permit. The PDMP documents the operator's IPM practices.

The operator's IPM practices shall consider the following for each pesticide use pattern:

(Note: If the operator's discharge of pollutants results from the application of a pesticide that is being used solely for the purpose of "pesticide research and development," as defined in 9VAC25-800-10, the operator is only required to fully implement IPM practices to the extent that the requirements do not compromise the research design.)

(1) Mosquito and other flying insect pest control. This subpart applies to discharges resulting from the application of pesticides 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, but are not limited to, mosquitoes and black flies.

(a) Identify the problem. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall consider the following for each pest management area:

(i) Identify target mosquito or flying insect pests;

(ii) Establish densities for larval and adult mosquito or flying insect pest populations to serve as action thresholds for implementing pest management strategies;

(iii) Identify known breeding sites for source reduction, larval control program, and habitat management; and

(iv) 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.

(b) Pest management. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall select and implement for each pest management area efficient and effective means of pest management that minimize discharges resulting from application of pesticides to control mosquitoes or other flying insect pests. In developing these pest management strategies, the operator shall evaluate the following management options, considering impact to water quality, impact to nontarget organisms, pest resistance, feasibility, and cost effectiveness:

(i) No action;

(ii) Prevention;

(iii) Mechanical or physical methods;

(iv) Cultural methods;

(v) Biological control; and

(vi) Pesticides.

(c) Pesticide use. If a pesticide is selected to manage mosquitoes or flying insect pests and application of the pesticide will result in a discharge to surface waters, the operator shall:

(i) Conduct larval or adult surveillance prior to each pesticide application to assess the pest management area and to determine when action thresholds are met that necessitate the need for pest management;

(ii) Assess environmental conditions (e.g., temperature, precipitation, and wind speed) in the treatment area prior to each pesticide application to identify whether existing environmental conditions support development of pest populations and are suitable for control activities;

(iii) Reduce the impact on the environment and on nontarget organisms by applying the pesticide only when the action threshold has been met;

(iv) 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 larval action thresholds have been met; and

(v) 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 adult action thresholds have been met.

(2) Aquatic weed and algae control. This subpart applies to discharges resulting from the application of pesticides to control invasive or other aquatic (emergent, floating, or submerged) nuisance weeds and algae in surface waters. Aquatic nuisance weeds include, but are not limited to, cattails, hydrilla, and watermeal.

(a) Identify the problem. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall consider the following for each pest management area:

(i) Identify target weed and algae;

(ii) Identify areas with aquatic weed or algae problems and characterize the extent of the problems, including, for example, water use goals not attained (e.g., wildlife habitat, fisheries, vegetation, and recreation);

(iii) Identify possible factors causing or contributing to the weed or algae problem (e.g., nutrients, invasive species, etc); and

(iv) Establish past or present aquatic weed or algae densities to serve as action thresholds for implementing pest management strategies.

(b) Pest management. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall select and implement, for each pest management area, efficient and effective means of pest management that minimize discharges resulting from application of pesticides to control aquatic weeds or algae. In developing these pest management strategies, the operator shall evaluate the following management options, considering impact to water quality, impact to nontarget organisms, pest resistance, feasibility, and cost effectiveness:

(i) No action;

(ii) Prevention;

(ii) Reduce the impact on the environment and nontarget organisms by evaluating site restrictions, application timing, and application method in addition to applying the pesticide only when the action threshold has been met.

(4) Forest canopy pest control. This subpart applies to discharges resulting from the aerial application of pesticides to the 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 surface water.

(a) Identify the problem. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application in that calendar year, the operator shall consider the following for each pest management area:

(ii) Establish target pest densities to serve as action thresholds for implementing pest management strategies; and

(iii) Identify current distribution of the target pest and assess potential distribution in the absence of control measures.

(b) Pest management. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall select and implement for each pest management area efficient and effective means of pest management that minimize discharges resulting from application of pesticides to control forestry pests. In developing these pest management strategies, the operator shall evaluate the following management options, considering impact to water quality, impact to nontarget organisms, pest resistance, feasibility, and cost effectiveness:

(i) No action;

(ii) Prevention;

(iii) Mechanical or physical methods;

(iv) Cultural methods;

(v) Biological control; and

(vi) Pesticides.

(c) Pesticide use. If a pesticide is selected to manage forestry pests and application of the pesticide will result in a discharge to surface waters, the operator shall:

(i) Conduct surveillance prior to each application to assess the pest management area and to determine when the pest action threshold is met that necessitates the need for pest management;

(ii) Assess environmental conditions (e.g., temperature, precipitation, and wind speed) in the treatment area to identify conditions that support target pest development and are conducive for treatment activities;

(iii) Reduce the impact on the environment and nontarget organisms by evaluating the restrictions, application timing, and application methods in addition to applying the pesticide only when the action thresholds have been met; and

(iv) Evaluate using pesticides against the most susceptible developmental stage.

2. Water quality-based effluent limitations. The operator's discharge of pollutants must be controlled as necessary to meet applicable numeric and narrative water quality standards.

If at any time the operator become aware, or the board determines, that the operator's discharge of pollutants causes or contributes to an excursion of applicable water quality standards, corrective action must be taken as required in Part I D 1 of this permit.

B. Monitoring requirements.

1. Monitoring requirements for pesticide applicators.

a. 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.

b. 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.

c. 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.

2. Visual monitoring assessment requirements for all operators. All operators covered under this permit must conduct a visual monitoring assessment (i.e., spot checks in the area to and around where pesticides are applied) for possible and observable adverse incidents caused by application of pesticides, including but not limited to the unanticipated death or distress of nontarget organisms and disruption of wildlife habitat, recreational, or municipal water use.

A visual monitoring assessment is only required during the pesticide application when feasibility and safety allow. For example, visual monitoring assessment is not required during the course of treatment when that treatment is performed in darkness as it would be infeasible to note adverse effects under these circumstances. Visual monitoring assessments of the application site must be performed:

a. During any post-application surveillance or efficacy check that the operator conducts, if surveillance or an efficacy check is conducted.

b. During any pesticide application, when considerations for safety and feasibility allow.

C. Pesticide discharge management plan (PDMP). Any operator applying pesticides and exceeding the annual application thresholds established in 9VAC25-800-30 C must prepare a PDMP for the pest management area. The plan must be kept up-to-date thereafter for the duration of coverage under this general permit, even if discharges subsequently fall below the annual application threshold levels. The operator applying pesticides shall develop a PDMP consistent with the deadline outlined in Table I-1 below.

Table I-1. Pesticide Discharge Management Plan Deadline
Category	PDMP Deadline
Operators who know prior to commencement of discharge that they will exceed an annual treatment area threshold identified in 9VAC25-800-30 C for that year.	Prior to first pesticide application covered under this permit.
Operators who do not know until after commencement of discharge that they will exceed an annual treatment area threshold identified in 9VAC25-800-30 C for that year.	Prior to exceeding an annual treatment area threshold.
Operators commencing discharge in response to a declared pest emergency situation as defined in 9VAC25-800-10 that will cause the operator to exceed an annual treatment area threshold.	No later than 90 days after responding to declared pest emergency situation.

The PDMP does not contain effluent limitations; the limitations are contained in Parts I A 1 and I A 2 of the permit. The PDMP documents how the operator will implement the effluent limitations in Parts I A 1 and I A 2 of the permit, including the evaluation and selection of control measures to meet those effluent limitations and minimize discharges. In the PDMP, the operator may incorporate by reference any procedures or plans in other documents that meet the requirements of this permit. If other documents are being relied upon by the operator to describe how compliance with the effluent limitations in this permit will be achieved, such as a pre-existing integrated pest management (IPM) plan, a copy of any portions of any documents that are being used to document the implementation of the effluent limitations shall be attached to the PDMP.

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

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

c. The date(s) and time(s) analyses were performed;

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

e. The analytical techniques or methods used; and

f. The results of such analyses.

2. The operator shall retain records of all monitoring information, including all calibration and maintenance records and copies of all reports required by this permit for a period of at least three years from the date that coverage under this permit expires. This period of retention shall be extended automatically during the course of any unresolved litigation regarding the regulated activity or regarding control standards applicable to the operator, or as requested by the board.

C. Reporting monitoring results. Monitoring results under this permit are not required to be submitted to the department. However, should the department request that the operator submit monitoring results, the following subdivisions would apply.

1. The operator shall submit the results of the monitoring required by this permit not later than the 10th day of the month after monitoring takes place, unless another reporting schedule is specified elsewhere in this permit. Monitoring results shall be submitted to the department's regional office.

2. Monitoring results shall be reported on a discharge monitoring report (DMR) or on forms provided, approved, or specified by the department.

3. If the operator monitors any pollutant specifically addressed by this permit more frequently than required by this permit using test procedures approved under 40 CFR Part 136 or using other test procedures approved by the U.S. Environmental Protection Agency or using procedures specified in this permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted on the DMR or reporting form specified by the department.

4. Calculations for all limitations that require averaging of measurements shall utilize an arithmetic mean unless otherwise specified in this permit.

D. Duty to provide information. The operator shall furnish to the department, within a reasonable time, any information that the board may request to determine whether cause exists for modifying, revoking and reissuing, or terminating this permit or to determine compliance with this permit. The board may require the operator to furnish, upon request, such plans, specifications, and other pertinent information as may be necessary to determine the effect of the wastes from his discharge on the quality of state waters, or such other information as may be necessary to accomplish the purposes of the State Water Control Law. The operator shall also furnish to the department, upon request, copies of records required to be kept by this permit.

E. Compliance schedule reports. Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of this permit shall be submitted no later than 14 days following each schedule date.

F. Unauthorized discharges. Except in compliance with this permit, or another permit issued by the board, it shall be unlawful for any person to:

1. Discharge into state waters sewage, industrial wastes, other wastes, or any noxious or deleterious substances; or

2. Otherwise alter the physical, chemical, or biological properties of such state waters and make them detrimental to the public health, to animal or aquatic life, or to the use of such waters for domestic or industrial consumption, recreation, or other uses.

G. Duty to comply. The operator shall comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the State Water Control Law and the federal Clean Water Act, except that noncompliance with certain provisions of this permit may constitute a violation of the State Water Control Law but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or denial of a permit renewal application.

The operator shall comply with effluent standards or prohibitions established under § 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions, even if this permit has not yet been modified to incorporate the requirement.

H. Duty to reapply.

1. If the operator wishes to continue an activity regulated by this permit after the expiration date of this permit, and the operator does not qualify for automatic permit coverage renewal, the operator shall submit a registration statement at least 30 days before the expiration date of the existing permit, unless permission for a later date has been granted by the board. The board shall not grant permission for registration statements to be submitted later than the expiration date of the existing permit.

2. An operator qualifies for automatic permit coverage renewal and is not required to submit a registration statement if:

a. The operator information has not changed since this general permit went into effect on April 10, 2011; and

b. The board has no objection to the automatic permit coverage renewal for this operator based on performance issues or enforcement issues. If the board objects to the automatic renewal, the operator will be notified in writing.

Any operator that does not qualify for automatic permit coverage renewal shall submit a new registration statement in accordance with Part II H 1.

I. Effect of a permit. This permit does not convey any property rights in either real or personal property or any exclusive privileges, nor does it authorize any injury to private property or invasion of personal rights, or any infringement of federal, state, or local law or regulations.

J. State law. Nothing in this permit shall be construed to preclude the institution of any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Nothing in this permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance.

K. Oil and hazardous substance liability. Nothing in this permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law.

L. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) that are installed or used by the operator to achieve compliance with the conditions of this permit. Proper operation and maintenance also include effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of backup or auxiliary facilities or similar systems that are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this permit.

M. Disposal of solids or sludges. Solids, sludges, or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering state waters.

N. Duty to mitigate. The operator shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit that has a reasonable likelihood of adversely affecting human health or the environment.

O. Need to halt or reduce activity not a defense. It shall not be a defense for a operator in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.

P. Inspection and entry. The operator shall allow the director, or an authorized representative, upon presentation of credentials and other documents as may be required by law, to:

1. Enter upon the operator premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this permit;

2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this permit;

3. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this permit; and

4. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as otherwise authorized by the Clean Water Act and the State Water Control Law, any substances or parameters at any location.

For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency.

Q. Permit actions. Permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a permit modification, revocation and reissuance, termination, or notification of planned changes or anticipated noncompliance does not stay any permit condition.

R. Transfer of permits.

1. Permits are not transferable to any person except after notice to the department. Except as provided in Part II R 2, a permit may be transferred by the operator to a new owner or operator only if the permit has been modified or revoked and reissued, or a minor modification made, to identify the new operator and incorporate such other requirements as may be necessary under the State Water Control Law and the Clean Water Act.

2. As an alternative to transfers under Part II R 1, this permit may be automatically transferred to a new operator if:

a. The current operator notifies the department within 30 days of the transfer of the title to the facility or property;

b. The notice includes a written agreement between the existing and new operator's containing a specific date for transfer of permit responsibility, coverage, and liability between them; and

c. The board does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part II R 2 b.

S. Severability. The provisions of this permit are severable, and if any provision of this permit or the application of any provision of this permit to any circumstance is held invalid, the application of such provision to other circumstances, and the remainder of this permit, shall not be affected thereby.
