Fred Christiansen, Technician 1 HENDERSON COUNTY — PESTICIDE DICHARGE MANAGEMENT PLAN (PDMP) B. PEST MANAGEMENT AREA DESCRIPTION (5.1.2). I. Henderson County has a population of 107,177 and is located in southwestern North Carolina bordered to the north by Buncombe County and to the east by Rutherford and Polk, the west by Transylvania County and to the south by South Carolina. It has an altitude ranging from 1400 feet to 5000 feet. Henderson County is located on an intermountain plateau and is almost circled by mountains. The French Broad river basin extends through the county entering on the west and existing to the north. The total area is 239,962.94 acres or 374.94 square miles. Henderson County has at least 24 summer camps which attract thousands of young people each year. The county is a tourist destination. There are two state parks in the county and the Pisgah National Forest is accessed from this county. Mosquito problems can be found county -wide especially in developed areas adjacent to woodlands and flood plains. PA HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT PLAN (PDMP) a. Natural Environments i. Temporary Woodland Pools: Shallow, temporary pools are common in woodland areas during the spring, summer, and fall months in Henderson County. These low lying areas or small depressions is where a variety of mosquito species will breed, most commonly Ochlerotatus Canadensis, Ochlerotatus infirmatus, Psorophora ferox, and Aedes vexans. These mosquitoes lay their eggs along the edges of the pool which hatch when rainwater from heavy rainstorms or hurricanes fill these pools. ii Freshwater Ponds: The larvae of Anopheles are found primarily in small ponds among the emergent vegetation. Ponds clogged with vegetation can breed large numbers of mosquitoes because of the vast amounts of organic matter available to mosquito larvae for feeding and because fish and other aquatic predators cannot readily feed on the, larval mosquitoes. iii Streams and Floodplains: Streams with running water rarely produce mosquitoes. However, mosquitoes need to be near water in order to lay their eggs. Anopheles and Culex mosquitoes are two types of species that can sometimes be found in isolated pockets adjacent to streams or within floodplain areas that undergo periodic flooding. iv.Tree Holes and Other Natural Containers: Natural containers such as pitcher plants, tree holes, or water trapped in or on plant leaves can serve as egg laying habitats for mosquitoes such as Ochlerotatus triseriatus. Frequent rainfalls maintain standing water within these types of microhabitats and can breed mosquitoes throughout the summer v. Swamps: Mosquitoes, such as Coquilletidia perturbans, breed in freshwater marshes and swamps consisting of emergent vegetation. These types of habitats can occur in both woodlands and open fields. Larvae attach themselves to the stems and roots of the vegetation to obtain oxygen, and do not need to swim up and down in the water column to feed and to breath. Due to this adaptation, these larvae can avoid exposure to predatory fish. b. Man-made Environments i. Stormwater/Wastewater Detention: A catch basin typically includes a curb inlet where storm water enters the basin to capture sediment, debris and associated pollutants. Similarly, detention/retention basins that perform similar functions for other types of wastewaters, such as waste treatment settlement ponds, provide a similar type of habitat to that of the storm water catch basin. These detention basins provide egg laying habitat for urban mosquito species such as Culex quinquefasciatus. Moisture and organic debris capture within the detention basin can aid in development and provide nutrients for growing larvae. ii. Livestock pastures: Pastures can pose a serious problem to mosquito abatement agencies, as the livestock not only provide a reliable blood meal for female mosquitoes, but form numerous larval habitats from their hoof prints. Mosquito species associated with pastures include Aedes vexans, Culex quinquefasciatus, and Psorophora columbiae. HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT PLAN (PDMP) iii. Artificial Containers: Containers left out to collect rainwater such as tires, bottles, buckets, children's toys, boats, and birdbaths can provide an excellent mosquito egg laying habitat free from any predators. Many treehole mosquitoes have learned to adapt to suing these man made mosquito nurseries. Aedes albopictus, our most common pest species, lay their eggs in these artificial containers. The abundance of organic debris, which can also collect in these containers, allows for the proliferation of mosquito production during a season. iv. Clear -cuts: These areas are the result of logging operations for the timber industry or future residential subdivisions. Often such work tends to scar the land with trenches and ruts from heavy equipment used in the process. These newly established "lows" can hold water for prolonged periods of time, especially without the aid of water translocation previously carried out by the now absent forest. Often such sites are productive as larval mosquito sites until they are developed or regenerated. Initially, such sites may harbor Culex mosquitoes, including Culex quinquefasciatus, because of the excess of rotting plant material left after clear -cutting work. 2. Pest Problem Description: The county is known to contain over 15 species of mosquitoes, although Henderson County Vector Control actively surveys and conducts control efforts primarily on 15 species (listed below). Other mosquito species (primarily in the Ochlerotatus and Culex genus) found in the county may cause nuisance problems when populations build up after county -wide rain or river flooding events and could potentially be a disease threat for our area. a. Mosquito species i. Aedes albopictus "Asian Tiger Mosquito": This mosquito is a container -inhabiting species which lays its eggs in any water -containing receptacle in urban and rural areas. This species is a know vector of West Nile Virus, Dengue Fever, and St. Louis Encephalitis here in the United States. Its primary habitats are artificial containers such as tires, plant trivets, buckets, boats, children's toys, rain gutters, air conditioning units, ornamental ponds, and any container that holds water. They typically are associated with junk piles and/or tire dumps and have invaded many countries throughout the world through the transport of goods. Larvae can also be found in natural containers such as tree holes and leaf axils. Aedes albopictus is a major nuisance mosquito in Henderson County during the summer months and is associated with rain events. This mosquito only travels a short distance and is a very aggressive daytime biter with peaks generally occurring during the early morning and late afternoon. This mosquito species is hard to treat using adulticide spray because it is found in all stages of its life cycle and is a daytime biter. Public education and source reduction works best for treatment of this species. ii. Aedes cinereus: This is an early -season mosquito, preferring to inhabit swamps and bogs. iii Aedes vexans: This mosquito can be found in many different habitats. Among these are: open rain pools, tire ruts and storm water basins, to name a few. Aedes vexans is a w serious nuisance pest and has been implicated as a vector of Eastern Equine Encephalitis (EEE), West Nile Virus (WVN), HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT PLAN (PDMP) and dog heartworm. Females will feed in shady places during the day; however, they are very active at dusk and vigorously seek blood meals at this time. iv. Anopheles bradleyi/crucians complex: The larvae of this mosquito are found in margins of swamps and semi -permanent and permanent pools associated with aquatic vegetation. This mosquito prefers acid water in the larval habitat. Females bite at night and during the day in the woods and they may also enter houses. This species is capable of harboring malaria but is not considered the primary mosquito responsible for the disease's transmission. V. Anophelies punctipinnis: One of the first Anopheles mosquitoes to emerge in spring. This is a vicious biter that will enter a home. vi. Anopheles crucians: This is a complex of three closely -related species. This mosquito is medium-sized with a dark body. The mosquito prefers to breed in semi and permanent pools, lakes, ponds and swamps. It is a nigh -biter of mammals. vii. Anopheles quadrimaculatus: "common malaria mosquito": This is the chief malaria vector in the U.S. this is a large, dark -brown mosquito. It prefers to lay eggs in well - developed beds of submergant, floating leaf or emergent aquatic vegetation. viii Coquillettidia perturbans: This large, salt and pepper mosquito is found in established, permanent freshwater marshes containing emergent vegetation (usually around cattails) where there is a layer of detritus on the marsh bottom. The eggs are laid in a raft on the water surface, and the larvae attach to the roots of the emergent plants. This aggressive mosquito is active for short periods at dusk and commonly flies three to five miles, often much farther. Females bite both humans and birds. This species is generally considered a bridge vector of EEE to mammals, but has also tested positive for WNV in the United States. ix. Culex erraticus: This small species is found around creek edges and near flood plains and is common in summer and early fall. Culex erraticus are opportunistic feeders and usually feed on mammals, reptiles, amphibians and birds. The females may bite at night and have been implicated in disease transmission. X. Culex pipiens — "common house mosquito": Vector of WNV, SLE. Very common mosquito, prefers to breed in containers. Birds are the preferred blood source. xi. Culex restuans — "white -dotted mosquito": An important vector of SLE & WNV. Birds are its preferred blood -source. xii. Culex salinarius: This mosquito is widespread and is found in greatest abundance along the Atlantic and Gulf Coasts of the Untied States. Larvae are found in fresh or brackish water that contains a great deal of emergent and decaying vegetation. These mosquitoes are opportunistic blood feeders and will typically feed on other mammals and occasionally will feed on man. They are one of the most likely bridge vectors involved in the human transmission cycle of West Nile Virus (WNV) and Eastern Equine Encephalomyelitis Virus (EEE) in the northeastern USA. They are also efficient vectors of St. Louis Encephalitis (SLE). Controlling Culex salinarius is difficult because the dense vegetation in their larval habitat offers protection from both predators and pesticides. xiii. Ochlerotatus canadensis Canadensis: This mosquito prefers pools with a bottom of dead and decaying leaves, although larvae are also found in roadside puddles, sink holes, wooded swamps and isolated pools of water in woodland streams. The females HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT PLAN (PDMP) of this species are described as persistent biters that attack readily in shaded situations throughout most of the day. This mosquito rarely migrates far from its larval habitats. The feeding behavior of the female adult may cause great nuisance to their host species and bites can be painful. xiv. Ochlerotatus sticticus: An uncommonly -found mosquito, except in river flood -plains. Will bite humans. xv. Ochlerotatus trivitattus: Habitat is usually flood -plains and woodland pools. A common "day -biter", but will bite in early mornings and evenings. xvi. Psorophora ferox "YYhite-Footed Mosquito ": This common, blue -black, medium sized mosquito is easily recognized by its white "feet". It breeds in woodland pools and adjacent ditches after heavy rains. They can be a nuisance to humans and animals I the woods, day or night and are very fierce biters. This species is usually found in late summer and early fall around Henderson County. 3. Action Threshold a. Action thresholds help determine when the use of pesticide maybe necessary to control mosquitoes. Listed below are the thresholds used for controlling adult mosquitoes through ULV adulticiding efforts. The goal is to control anthropophagus and disease carrying mosquitoes. i. > 5 landing rate count from staff at an inspection site; ii. > 5 complaint calls from a single ULV spray zone during a week; iii. Whenever WNV, EEE or Lacrosse Encephalitis have been detected in an area; iv. Based on a service request, limited area treatments may be conducted prior to special events or community functions. b. Action thresholds help determine when the use of pesticide is necessary to control mosquitoes. Listed below are the thresholds used for controlling juvenile mosquitoes through larviciding efforts. The goal is to control anthropophagus and disease carrying mosquitoes. i. Treatment of larval mosquito habitat may be conducted in areas that are found to contain an average of at least 1 larva per dip (Using a standard dipper). Actual treatments will be based on local demographics, mosquito species present, and other historic and current conditions. ii. Storm water systems may be treated in selected areas of the county where vector species have been found. iii. A number of known historic breeding sites may be treated due to the insufficient time to inspect and treat all larval sites within the county after a major rain event. 4. General location — The attached map shows the areas to be treated with adulticides. These areas have been established historically as a result of service requests and landing counts. G HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT PLAN (PDMP) 5. Water Quality Standards — Waterways in Henderson County are not known to be impaired by any pesticides used by Henderson County Mosquito control based on information for the NC Division of Water Quality (DWQ). C. CONTROL MEASURE DESCRIPTION 1. A description of the site specific control measures to demonstrate how staff specifically plan to reduce pesticide discharge and meet the applicable technology -based or water quality -based effluent limitations. a. Prevention and cultural methods are important components of our mosquito control program. Public education is conducted through complaint response, website, link to NCM & VCA media, and public service announcements. Prevention can be accomplished by removing containers and articles from yards that provide larval habitat, and to being mindful that birdbaths and pet water bowls could produce mosquitoes when not properly maintained. b. Pesticides are often the last choice used for control measures. These products are applied as directed by their respective label, and all equipment used in this process is closely monitored and calibrated by staff. Staff must consider impact to non -target organisms and water quality, pest resistance, feasibility, and cost effectiveness when evaluating and selecting the most efficient and effective means of pest management in order to minimize pesticide discharge to waters of the U.S. c. Biological control agents (larvicides) are utilized for controlling mosquito larvae. Formulations containing Bacillus sphaericus, Bacillus thuringensis israeleusis and/or 9 methoprene are placed in areas of long-term standing waters resulting from flooding and in catch -basins/ storm drains. These products are applied consistent to their labels. 2. Control measures are evaluated separately on the basis of mosquito life stages as follows: a. Control efficacy of adults is determined by pre and post -treatment landing counts and is supplemented by complaints within the treatment area. b. Larval control efficacy is more difficult to access since some of our larvicide products are growth hormones that do not cause mortality until the later stages of the larva's development. Often, in this case, a failure is not realized until "healthy" adults are found emerging after their pupal stage. However, post -treatment surveys do verify successful treatments when using biological control measures, such as Bti products. D. SCHEDULES AND PROCEDURES (5.1.3.1) Pertaining to control measures used and documentation required to comply with effluent limitations. 1. Spill Prevention Procedures a. Perform daily and weekly inspections of chemical storage buildings and pumping systems and maintain to full and proper function ability. b. Henderson County has established procedures for the vector -control program, which include the following: HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT (PDMP) i. Procedures for filling the pesticide storage tank and the pesticide tank on the spray truck. ii. Recommendations for spill management from the North Carolina Department of Agriculture's "Applying Pesticides Correctly" manual. iii. Material safety data sheets (MSDS) and labels of pesticides utilized which describe storage and spill procedures as well as personal protective equipment (PPE) requirements. iv. Spill response supplies and PPE listing and locations. v. Procedures for reporting hazardous materials incidents. 2. Pesticide Application Equipment Procedures a. Ground Adulticiding — ULV Sprayer i. Operations 1. Refer to manufacturer's manual 2. Application equipment must be calibrated annually to confirm the application rate is in accordance with the pesticide label. 3. Flow rates and Smart Flow systems should be checked periodically to ensure proper application rates 4. Visually inspect the spray equipment prior to use for leaks or wear in the lines, tanks, and nozzle each day before use and make any necessary adjustments and / or repairs 10 5.

Application equipment must be calibrated to confirm the application rate is in accordance with the pesticide label. c. Ensure that the product tank has sufficient chemical for each assigned task. d. Ensure equipment has battery supply. 2. Maintenance a. Refer to all maintenance procedures as outlines in the original manufacturer's specifications and recommendations. 3. Pest Surveillance Procedures a. Adult Surveillance Procedures i. Landing rate counts are utilized at inspection sites or at service requests to survey for adult mosquito densities. ii. Service requests often require inspections and are received during normal working hours or through phone messages or emails outside of the normal work day. Most calls are requests for treatments and sometimes reveal problems needing attention. Staff will check for adult mosquitoes to determine if a treatment is warranted. Typically, these requests for service stem from localized container -producing mosquitoes that are controlled by dumping water from buckets, birdbaths, and tarps, or removing tires and other containers that hold water. This will prevent the further production of adult mosquitoes. b. Larval Surveillance Procedures 12 i. Mosquito production sites are inspected by staff after flooding events caused by rains or high river stages. Larval surveillance includes locating the larval source (if not know), sampling for larvae, estimating larval density, determining larval developmental stage(s), and collecting larvae for identification purposes. ii. Service requests often require inspections that are received during normal working hours or through phone messages or emails outside of the normal work day. Most calls are requests for treatments and sometimes reveal problems needing attention. Staff will check for juvenile mosquitoes to determine if a treatment is warranted. Typically, these requests for service stem from localized container -producing mosquitoes that are controlled by HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT PLAN (PDMP) dumping water from buckets, birdbaths, and tarps, or removing tires and other containers that hold water. Occasionally service requests will reveal problems such as blocked drainage systems, leaking septic tanks, or broken water lines. c. Assessing Environmental Conditions Procedures General Considerations. Climatic conditions are always checked prior to any ground applications. Wind speed, wind direction, and the possibility of impending rain must be taken into consideration because of drift, dilution, or chemical breakdown depending on the -product being used. Temperature also plays a role in our application methods. No applications are made when temperatures fall below 50°F. ii. Adult mosquito treatments. Treatments for adult mosquitoes occur in both urban and rural areas of the county. Applicators are always aware of nearby wetlands and turn spray equipment off when necessary to avoid drift into such areas. Similarly, equipment is also turned off then approaching large bodies of water, such as lakes and ponds to avoid any adverse reactions to non -target organisms in these environments. 1. Ground Adulticiding Procedures a. Apply when insects are most active and meteorological conditions are conducive to keeping the spray cloud in the air column close to the ground. b. Apply during the cooler hours of the night or early morning when thermal activity is low. Do not apply when ambient temperature is less than 50°F c. Apply when ground wind speeds are equal to or greater than 1 mph. d. Do not apply over bodies of water (lakes, rivers, permanent streams, natural ponds, commercial fish ponds, swamps or marshes), except when necessary to target areas where adult mosquitoes are present, and weather conditions will facilitate movement of applied material 13 away from the water in order to minimize incidental deposition into the water body. Pesticide is highly toxic to bees exposed to direct treatment on blooming crops or weeds. Do not apply product or allow drift when bees are actively visiting the treatment area, except when applications are made to prevent or control a threat to public and/or animal health determined by a state or local health or vector control agency on the basis of documented evidence of disease causing agents in vector mosquitoes, or occurrence of mosquito -borne disease in animal or human populations, or if specifically approved by the state during a natural disaster recovery effort. HENDERSON COUNTY — PESTICIDE DISCHARGE MANAGEMENT PLAN (PDMP) f. A record for all Beekeepers, Do Not Sprays, and Notifications in the county is maintained and available to staff. All citizens that request to be notified are notified prior to their zone being adulticided. iii. Larval mosquito treatments. Two major environmental considerations are tree canopy and the amount of aquatic vegetation present within the treatment site. Tree canopy may deflect or otherwise prevent the penetration of pesticide from reaching the target area. Heavy vegetation within a wetland can interfere with the migration of the larviciding agent through the water column. E. OTHER ACTIONS NECESSARY TO MINIMIZE DISCHARGES (5.1.3.2) 1. Spill Response Procedures — the Henderson County Vector Control Handbook includes procedures for stopping, containing, and cleaning up leaks, spill, and other releases as well as procedures for notification of appropriate facility personnel, emergency response agencies, and regulatory agencies. a. Recommendations for spill management form the North Carolina Department of Agriculture's "Applying Pesticides Correctly" manual. b. MSDS and labels of pesticides utilized which describe storage and spill procedures as well as PPE requirements. c. Spill response supplies and PPE listing and locations. d. Procedures for reporting hazardous material incidents. 2. Adverse Incident Response Procedures (6.4) a. Twenty -Four (24) Hour Adverse Incident Notification (6.4.1) — All pertinent information regarding any adverse incident observed and necessary remediation will be documented. We will also utilize the procedures for reporting hazardous materials incidents found in the NHC Vector Control Handbook if adverse incidents are spill related. If an adverse incident has been observed as defined in Appendix A of the NC PGP, which may have resulted from a discharge of the pesticide we use, we will immediately notify the NC DENR Regional Incident Reporting Contact. 14 This notification should be made by telephone within 24 hours of becoming aware of the adverse incident and should include the following information: i.
