If on skin or clothing:
• Take off contaminated clothing.
• Rinse skin immediately with plenty of water for 15-20 minutes.
• Call a poison control center or doctor for treatment advice.

If in eyes:
• Hold eyes open and rinse slowly and gently with water for 15-20 minutes.
• Remove contact lenses, if present, after 5 minutes, and then continue rinsing eyes. • Call a poison control center or doctor for treatment advice.

If swallowed:
• Call a poison control center or doctor immediately for treatment advice.
• Have person sip a glass of water if able to swallow.
• Do not induce vomiting unless told to do so by a poison control center or doctor. • Do not give anything by mouth to an unconscious person.
When performing tasks with potential for contact with liquid fumigant, all handlers (including applicators) must wear: • Long-sleeved shirt and long pants, • Chemical-resistant gloves, • Chemical-resistant apron, • Protective eyewear (Do NOT wear goggles), and • Chemical-resistant footwear with socks.
The PPE required when handling liquid fumigant must be immediately available and must be worn if the handler is to perform any handling activity with a potential for liquid fumigant contact.
1. All handlers (including applicators) must wear a half-face air-purifying respirator (except when handlers are in enclosed cabs or applying the fumigant with equipment that disrupts the chisel trace and seals the soil at the same time, e.g., Yetter applicator) equipped with an organic-vapor (OV, NIOSH approval number prefix TC-23C) cartridge and a particulate pre-filter (Type N, R, P or HE, NIOSH approval number prefix TC-84A).
If sensory irritation (tearing, burning of the eyes or nose) is experienced and handlers remain in the application block or buffer zone, handlers must wear at a minimum either: • A NIOSH certified full facepiece air-purifying respirator equipped with an organic vapor (OV, NIOSH approval prefix TC-23C) cartridge and a particulate pre-filter (Type N, R, P, or HE, NIOSH approval number prefix TC-84A), or • A gas mask with a canister approved for organic vapor (NIOSH approval number prefix TC-14G). See Directions for Use, Air Monitoring Requirements, Respiratory Protection and Stop Work Triggers, number 1, Handlers Wearing Half-Face Air-Purifying Respirators for when an airpurifying respirator (full facepiece or gas mask) is required.
IMPORTANT: A self-contained breathing apparatus (SCBA) is not permitted for routine handler tasks.
If responding to an emergency, when corrective action is needed to reduce air concentrations to acceptable levels, wear an SCBA. Escape-only SCBA respirators must not be used by handlers for responding to emergencies. In addition wear PPE required for potential contact with liquid fumigant.
2. Handlers using enclosed cabs are not required to wear respiratory protection (not applicable in California) provided that the cab has been maintained according to the manufacturer's written operating instructions and there is written documentation that the ventilation system has been maintained according to the manufacturer's instructions and the enclosed cab is in conformance with the following requirements: • The enclosed cab must maintain a positive pressure of 6 mm H 2 O.
• The enclosed cab must have a minimum air intake flow of 43 m 3 /hour. • The enclosed cab must be equipped with activated charcoal filter media containing no less than 1000 grams of activated charcoal. • The filter must be changed after no more than 50 hours of application time.

USER SAFETY RECOMMENDATIONS Users should:
• Wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet.
• Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. • Remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing.

ENVIRONMENTAL HAZARDS
• This pesticide is toxic to mammals and birds. Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment washwaters or rinsate. • Chloropicrin has certain properties and characteristics in common with chemicals that have been detected in groundwater (chloropicrin is highly soluble in water and has low adsorption to soil). • For untarped applications of chloropicrin, leaching and runoff may occur if there is heavy rainfall after soil fumigation. • Groundwater Advisory: 1,3-dichloropropene is known to move through soil and under certain conditions has the potential to reach groundwater as a result of agricultural use. Application in areas where soils are permeable and groundwater is near the surface could result in groundwater contamination.
PHYSICAL OR CHEMICAL HAZARDS • Combustible. Do not use or store near heat or open flame. • Do not mix or allow coming in contact with oxidizing agent. A chemical reaction hazard may occur.
• Handle carefully! Do not drop or let container be impacted by heavy objects. An explosion hazard may occur.

DIRECTIONS FOR USE Restricted Use Pesticide
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only handlers may be in the application block from the start of the application until the entry restricted period ends, and in the buffer zone during the buffer zone period. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.
another person and granted that same person the right and full authority to manage and govern the use of such agricultural establishment is not an owner. See definition of "owner" in WPS (40 CFR §170.3). Roadway: Portion of a street or highway improved, designed or ordinarily used for vehicular travel, exclusive of the sidewalk or shoulder even if such sidewalk or shoulder is used by persons riding bicycles. In the event a highway includes two or more separated roadways, the term roadway shall refer to any such roadway separately. Representative Handling Task: For air monitoring, the locations and handler activities sampled must represent each handler's exposure occurring within the application block. For example, for an application consisting of a seven-handler crew (1 tractor driver, 1 tractor co-pilot, 4 shovelers, and 1 certified applicator supervising) two breathing zone samples could be collected: one sample for the tractor co-pilot and one sample for a downwind shoveler. Results of previous sampling may indicate which tasks and locations are worst case and therefore representative of all handlers.

Application Restrictions
• The use of this product is restricted to the methods described in this label.
• Do not formulate and/or tank mix this product into other end-use agricultural products.
• Soil fumigation using Pic-Clor 60 must be conducted only according to directions and conditions of use. • Chemigation: Do not apply Pic-Clor 60 through any type of irrigation system. • Not for use in greenhouses or other enclosed areas.
• An application block treated with Pic-Clor 60 must not be within 100 feet of an occupied structure. No person shall be present at this structure at any time during the seven consecutive day period after the application is complete. EXCEPTION: This restriction does not apply to use on soils that have not experienced a 1,3-Dichloropropene treatment in the previous two years, for example, on soils to be planted with fruit trees, nut and nursery crops, perennial vines, hops, mint or pineapple. • Pic-Clor 60 shall not be applied to soil more frequently than once each year.
• Do not apply within 100 feet of any well used for potable water. Do not apply this product within 100 feet from the edge of karst topographical features. Karst topography is identified from landscape features that result from the dissolving activity of water in carbonate rock formations (limestone, dolomite and marble). Surface features that are associated with karst topography include sinkholes, caverns, springs, and sinking or disappearing streams. • Use PIC-CLOR 60 only on soils that have a relatively shallow hard pan or soil layer restrictive to downward water movement (such as spodic horizon) within six feet of the ground surface and are capable of supporting seepage irrigation regardless of irrigation method employed.
• Use standard chisel injection equipment to inject PIC-CLOR 60 as deep as possible without placing the fumigant directly into the shallow subsurface irrigation water. • PIC-CLOR 60 may not be applied within 100 feet of drinking water wells.

Product Information
This product is a multi-purpose liquid fumigant for preplant treatment of soil to control nematodes, symphylans, wireworms and certain soil borne diseases in cropland. This product, a soil fungicide and nematicide, may be applied as a preplant soil treatment to control or to aid in reducing the damaging effects of certain soil borne diseases, such as potato scab (caused by Streptomyces scabies), soil rot (soil pox) of sweet potatoes, Granville (bacterial) wilt, black root rot and black shank diseases of tobacco, Verticillium wilt of mint, pink root of onions, and pod rot of peanuts. This product also controls plant parasitic nematodes, such as root-knot, root lesion, citrus, cyst formers (golden, sugar beet, soybean), burrowing, lance, reniform, ring, spiral, sting, pin, stubby root, stylet, dagger and certain others, as well as symphylans (garden centipedes) and wireworms. Before fumigation, soil sampling for the type and number of pests present is recommended. In fields where pre-treatment soil samples indicate the presence of high population levels of nematodes, a successful fumigation cannot be expected to eradicate entire populations. Therefore, post-treatment sampling is recommended to determine the need for additional pest management practices. Consult State Agricultural Experiment Station or Extension Service specialists for information on other practices such as post-harvest destruction of crop residues, weed control or other cultural practices, and use of nematode resistant crop varieties that may aid in reducing crop losses from soil borne pests.

Use Precautions Recontamination Prevention
Pic-Clor 60 will help manage certain soil borne pests that are present in the soil treatment zone at time of fumigation. It will not control pests that are introduced into soil after fumigation. To avoid reinfestation of treated soil do not use irrigation water, transplants, seed pieces, or equipment that could carry soil borne pests from infested land. Avoid contamination from moving infested soil onto treated beds through cultivation, movement of soil from below the treated zone, dumping contaminated soil in treated fields and soil contamination from equipment or crop remains. Clean equipment carefully before entering treated fields. Cultural practices, which provide post-harvest destruction of crop residues and weeds prior to fumigation and practices which prevent weed infestation following fumigation and prior to planting, will help prevent recontamination.

Equipment Clean-Up
Because Pic-Clor 60 is corrosive under certain conditions, flush all application equipment with fuel oil, kerosene or a similar type of petroleum solvent immediately after use. Fill pumps and meters with new motor oil or a 50% motor oil/fuel oil mixture before storing. Do not use water. Dispose of rinsate by incorporation into field just treated or by other approved means. Never introduce rinsate or unused Pic-Clor 60 into surface or underground water supplies. Fertility Interactions Fumigation may temporarily raise the level of ammonia nitrogen and soluble salts in the soil. This is most likely to occur when high rates of fertilizer and fumigant are applied to soils that are either cold, wet, acidic, or high in organic matter. To avoid injury to certain crops including red beets, carrots, corn, radishes, cole crops, legumes (beans), lettuce, onions, and sugarbeets, fertilize when possible as indicated by soil tests made after fumigation. Use only fertilizers containing nitrates until after the crop is well established and the soil temperature is above 65 o F. In mineral soils, do not apply more than 2/3 of the nitrogen requirements from fertilizers containing ammonium salts until the crop is well established and soil temperature is above 65 o F. To avoid ammonia injury or nitrate starvation (or both) to crops grown on high organic soils, do not use fertilizers containing ammonium salts. When using high rates of Pic-Clor 60 as required by certain state nursery regulations, liming of highly acid soils before fumigation may stimulate nitrification and reduce the possibility of ammonia toxicity. Certain nursery crops such as citrus seedlings, Cornus sp., Crataegus sp., spruce, and vegetable crops such as cauliflower have shown evidence of phosphorus deficiency following fumigation. To avoid this possible effect, additional phosphate fertilizer (foliar applied) is recommended where experience indicates a deficiency may occur.

Certified Applicator Training
Any certified applicator supervising a soil fumigant application must have successfully completed one of the soil fumigant training programs listed on the following EPA website www.epa.gov/fumiganttraining for the active ingredient(s) in this product. The training must be completed in the time frames listed on the website. The FMP must document the date and location where the soil fumigant training program was completed.

Handlers
The following activities are prohibited from being performed by anyone other than persons who have been appropriately trained and equipped as handlers in accordance with the requirements in WPS (40 CFR Part 170): • Monitoring fumigant air concentrations; • Cleaning up fumigant spills (this does not include emergency personnel not associated with the application); • Handling or disposing of fumigant containers; • Cleaning, handling, adjusting, or repairing the parts of application equipment that may contain fumigant residues; and • Performing any handling tasks as defined by the WPS (40 CFR 170). The following activities are prohibited from being performed in the application block from the start of the application until the entry restricted period ends and in the buffer zone during the buffer zone period by anyone other than persons who have been appropriately trained and equipped as handlers in accordance with the requirements in WPS (40 CFR Part 170). (NOTE: persons repairing and monitoring tarps are considered handlers for the duration listed below). Prohibited activities (except for trained and equipped handlers) include: • Participating in the application as supervisors, loaders, drivers, tractor co-pilots, shovelers, cross ditchers, or as other direct application participants; • Installing, repairing, operating, or removing irrigation equipment; • Performing scouting, crop advising, or monitoring tasks; • Installing, perforating (cutting, punching, slicing, poking), or removing tarps; and • Repairing or monitoring tarps until 14 days after application is complete if tarps are not perforated and removed during those 14 days.
NOTE: see Tarp Perforation and/or Removal section on this labeling for requirements about when tarps are allowed to be perforated.
Handlers do not include local, state, or federal officials performing inspection, sampling, or other similar official duties.

Protection for Handlers Supervision of Handlers:
For all applications, from the start of the application until the application is complete, a certified applicator must be at the application block in the line of sight of the application and must directly supervise all persons performing handling activities.
For handling activities that take place after the application is complete until the entry restricted period expires, the certified applicator is not required to be on-site, but must have communicated in a manner that can be understood by the site owner and handlers responsible for carrying out those activities the information necessary to comply with the label and procedures described in the FMP (e.g., emergency response plans and procedures).
IMPORTANT: This requirement does not override the requirements in the Worker Protection Standard for Agricultural Pesticides for information exchange between operators of agricultural establishments and commercial pesticide applicators.
The certified applicator must provide Fumigant Safe Handling Information to each handler or confirm that within the past 12 months, each handler has received Fumigant Safe Handling Information in a manner that he/she can understand. Fumigant Safe Handling Information will be provided where this product is purchased or at http://www.epa.gov/fumiganttraining. For all handling tasks at least two handlers must be present.
Exception: After the application is complete, only one trained handler is required to perform fumigant site monitoring tasks outside of the buffer zone.

Exclusion of Non Handlers from the Application Block and Buffer Zone:
The certified applicator supervising the application and the owner of the establishment where the application is taking place must make sure that all persons who are not trained and PPE-equipped and who are not performing one of the handling tasks as stated in this labeling are: • excluded from the application block during the entry restricted period, and • excluded from the buffer zone during the buffer zone period (see buffer zone exemption for transit on roadways in Buffer Zone Requirements section).
Local, state, or federal officials performing inspection, sampling, or other similar official duties are not excluded from the application block or the buffer zone by this labeling. The certified applicator supervising the application and the owner of the establishment where the application is taking place are not authorized to, or responsible for, excluding those officials from the application block or the buffer zone.

Providing, Cleaning, and Maintaining PPE:
The employer of any handler (as stated in this label) must make sure that all handlers are provided and correctly wear the required PPE. The PPE must be cleaned and maintained as required by the Worker Protection Standard for Agricultural Pesticides.

Air Purifying Respirator Availability:
The employer of any handler must confirm that an air-purifying respirator and appropriate cartridges/canisters of the type specified in the PPE section of this labeling are immediately available for each handler who will wear one (see Respirator Fit Testing, Medical Qualification, and Training section for additional requirements). Exception: Air-purifying respirators do not need to be made available for handlers performing fumigant site monitoring tasks outside of the buffer zone. Cartridges or canisters must be replaced when odor or sensory irritation from this product becomes apparent during use, if the measured concentration of chloropicrin is greater than or equal to 1.5 ppm, or after 8 hours of cumulative use, whichever occurs first.
Respirator Fit Testing, Medical Qualification, and Training: Using a program that conforms to OSHA's requirements (see 29 CFR Part 1910.134), employers must verify that any handler who uses a respirator is: • Fit-tested and fit-checked, • Trained, and • Examined by a qualified medical practitioner to ensure physical ability to safely wear the style of respirator to be worn. A qualified medical practitioner is a physician or other licensed health care professional who will evaluate the ability of a worker to wear a respirator. The initial evaluation consists of a questionnaire that asks about medical conditions (such as a heart condition) that would be problematic for respirator use. If concerns are identified, then additional evaluations, such as a physical exam, might be necessary. The initial evaluation must be done before respirator use begins. Handlers must be reexamined by a qualified medical practitioner if their health status or respirator style or use-conditions change. • Upon request by local/state/federal/tribal enforcement personnel, employers must provide documentation demonstrating how they have complied with these requirements.

Air Monitoring Requirements
• When air-purifying respirators (full facepiece or gas mask) are worn, air monitoring samples for chloropicrin must be collected at least every 2 hours in the breathing zone of a handler performing a representative handling task. • When breathing zone samples are required, they must be taken outside respiratory protection equipment and within a 10-inch radius of the handler's nose and mouth. • When using devices to monitor air concentration levels, a direct read detection device, such as an electronic device or a colorimetric device (e.g., Matheson-Kitagawa, Draeger, or Sensidyne) must be used. The devices must have sensitivity of at least 0.15 ppm for chloropicrin. Persons using direct read detection devices must follow the manufacturer's directions.

Handlers Wearing Half-Face Air-Purifying Respirators
(Handlers are required to start work in half-face air-purifying respirators.) The Air Monitoring Requirements section above must be followed.
• If at any time any handler experiences sensory irritation (tearing, burning of the eyes or nose) while wearing a half-face respirator then either: o (OPTION 1) An air-purifying respirator (full facepiece or gas mask) must be worn by all handlers who remain in the application block or surrounding buffer zone, or o (OPTION 2) Operations must cease and handlers not wearing air-purifying respirators (full facepiece or gas mask) must leave the application block and surrounding buffer zone. o During the collection of air samples an air-purifying respirator (full facepiece or gas mask) must be worn by the handlers taking the air samples.

Tarp Perforation and/or Removal IMPORTANT: Persons perforating, repairing, removing, and/or monitoring tarps are defined, within certain time limitations, as handlers (see Handlers section), and they must be provided the PPE and other protections for handlers as required on this labeling and in the Worker Protection Standard for Agricultural Pesticides.
Tarps must not be perforated until a minimum of 5 days (120 hours) have elapsed after the application is complete, unless a weather condition exists which necessitates early tarp perforation or removal (see Early Tarp Removal for Broadcast Applications Only and Early Tarp Perforation during Flood Prevention Activities for Bedded Applications Only requirements). If tarps are perforated within 14 days after the application is complete, tarp removal must not begin until at least 2 hours after tarp perforation is complete. If tarps are perforated but not removed within 14 days after the application is complete, planting or transplanting must not begin until at least 48 hours after the tarp perforation is complete.
If tarps are not perforated or removed within 14 days after the application is complete, planting or transplanting may take place while the tarps are being perforated. Each tarp panel used for broadcast application must be perforated. Tarps may be perforated manually ONLY for the following situations: o At the beginning of each row when a coulter blade (or other device which performs similarly) is used on a motorized vehicle such as an ATV. o In fields that are 1 acre or less. o During flood prevention activities. In all other instances tarps must be perforated (cut, punched, poked, or sliced) only by mechanical methods Tarp perforation for broadcast applications must be completed before noon. For broadcast applications, tarps must not be perforated if rainfall is expected within 12 hours. Early Tarp Removal for Broadcast Applications Only: o Tarps may be removed before the required 5 days (120 hours) if adverse weather conditions have compromised the integrity of the tarp, provided that the compromised tarp poses a safety hazard. Adverse weather includes high wind, hail, or storms that blow tarps off the field and create a hazard, e.g., tarps blowing into power lines and onto roads. A compromised tarp is a tarp that due to an adverse weather condition is no longer performing its intended function and is creating a hazard.

Early Tarp Perforation during Flood Prevention Activities for Bedded Applications Only:
o Tarp perforation is allowed before the 5 days (120 hours) have elapsed. o Tarps must be immediately retucked and packed after soil removal.

Entry Restricted Period and Notification Entry Restricted Period
Entry into the application block (including early entry that would otherwise be permitted under the WPS) by any person -other than a correctly trained and PPE-equipped handler who is performing a handling task listed on this labeling -is PROHIBITED from the start of the application until: • 5 days (120 hours) after the application is complete for untarped applications, or • 5 days (120 hours) after the application is complete if tarps are not perforated and removed for at least 14 days after the application is complete, or • 48 hours after tarp perforation is complete if tarps will be perforated within 14 days after the application is complete and will not be removed for at least 14 days after the application is complete, or • tarp removal is completed if tarps are both perforated and removed less than 14 days after the application is complete.

NOTES:
• See Tarp Perforation and/or Removal section on this labeling for requirements about when tarps are allowed to be perforated. • If early tarp removal occurs for a broadcast application the entry restricted period is a minimum of 5 days after the application is complete. • When listing application information for soil fumigant applications to comply with part 170.122 of the WPS, list the entry restricted period time frame in place of the REI.

Notification
Notify workers of the application by warning them orally and by posting Fumigant Treated Area signs. The signs must bear the skull and crossbones symbol and state: • "DANGER/PELIGRO" • "Area under fumigation, DO NOT ENTER/NO ENTRE" • "1,3-dichloropropene and chloropicrin fumigants in use" • The date and time of fumigation • The date and time entry restricted period is over • Pic-Clor 60, and • Name, address, and telephone number of the certified applicator in charge of the fumigation.
Post the Fumigant Treated Area sign instead of the WPS sign for this application, but follow all WPS requirements pertaining to location, legibility, text size, and sign size (40 CFR §170.120). Post Fumigant Treated Area signs at all entrances to the application block no sooner than 24 hours prior to application.
Fumigant Treated Area signs must remain posted for no less than the duration of the entry restricted period.
Fumigant Treated Area signs must be removed within 3 days after the end of the entry restricted period.

Mandatory Good Agricultural Practices (GAPs)
The following GAPs must be followed during all fumigant applications.

Application Timing
Apply Pic-Clor 60 at any time of the year when soil conditions permit. Conditions that allow rapid diffusion of the fumigant as a gas through the soil normally give the best results. Because Pic-Clor 60 does not provide residual control of soil pests, use it as a preplant application before planting each crop.
Tarps (when tarps are used in Pic-Clor 60 applications) • A written tarp plan must be developed and included in the FMP.
• Once a tarp is perforated, the application is no longer considered tarped.
• Tarps must be installed immediately after the fumigant is applied to the soil.

Weather Conditions
• To determine if unfavorable weather conditions exist or are predicted (see Identifying Unfavorable Weather Conditions section) and whether an application should proceed, the National Weather Service weather forecast must be checked by the certified applicator supervising the application: o on the day of, but prior to the start of the application, and o on a daily basis during the application if the time period from the start of the application until the application is complete is greater than 24 hours. • Do not apply if an air stagnation advisory issued by the National Weather Service is in effect for the area in which the application is planned, during the application, or the 48 hours after the application is complete. • Do not apply if light wind conditions (< 2 mph) are forecast to persist for more than 18 consecutive hours from the time the application starts until 48 hours after the application is complete. • Detailed National Weather Service forecasts for local weather conditions, wind speed, and air stagnation advisories may be obtained on-line at: http://www.nws.noaa.gov, on NOAA weather radio, or by contacting your local National Weather Service Forecasting Office.

Identifying Unfavorable Weather Conditions
Unfavorable weather conditions block upward movement of air, which results in trapping fumigant vapors near the ground. The resulting air mass can move off-site in unpredictable directions. These conditions typically exist within an hour prior to sunset and continue past sunrise and may persist as late as noontime. Unfavorable conditions are common on nights with limited cloud cover and light to no wind and their presence can be indicated by ground fog or smog and can also be identified by smoke from a ground source that flattens out below a ceiling layer and moves laterally in a concentrated cloud.

Soil Preparation
• Soil must be in good tilth and free of large clods. Large clods can prevent effective soil sealing and reduce effectiveness of the application. If subsurface soil compaction layers (hardpans) are present within the intended fumigation treatment zone, a deep tillage to fracture these layers must occur prior to or during the soil fumigant application. • Plant residue that is present must not interfere with the application or the soil seal. Nondecomposed plant material may harbor pests that will not be controlled by fumigation. Crop residue that is present must lie flat to permit the soil to be sealed effectively and limit the natural "chimneys" that may occur in the soil when plant residue is present. These "chimneys" allow the soil fumigants to move through the soil quickly and escape into the atmosphere. This may create potentially harmful conditions for workers and bystanders and limits the efficacy of the fumigant. Plant residue on the field serves to prevent soil erosion from both wind and water. • Trash pulled by the shanks to the ends of the field must be covered with tarp, or soil, depending on the application method before making the turn for the next pass.

Soil Temperature
• The minimum soil temperature at the depth of injection is 40°F.
• The maximum soil temperature at the depth of injection must not exceed 90°F at the beginning of the application. o If air temperatures have been above 100°F in any of the three days prior to the start of the application, then soil temperature must be measured and recorded in the FMP.
Record temperature measurements at the application depth or 12 inches, whichever is shallower.

Soil Sealing
• Broadcast Untarped Applications: Use a disc or similar equipment to uniformly mix the soil to at least a depth of 3 to 4 inches to eliminate the chisel or plow traces. Following elimination of the chisel trace, the soil surface must be compacted with a cultipacker, ring roller, and roller in combination with tillage equipment. When using equipment similar to the Yetter applicator (chisel trace disruption and soil sealing are done with one implement), additional tillage and compaction are not required. • Bedded Applications: Preformed beds must be sealed by disruption of the chisel trace using press sealers, bed shapers, cultipackers, or by reshaping (e.g., relisting, lifting and replacing) the beds immediately following injection. Beds formed at the time of application must be sealed by disrupting the chisel trace using press sealers or bed shapers. When bedding, prebedders such as ripper hippers, hillers, or other prebedders may be used to disrupt the chisel trace and seal the soil. When using equipment similar to the Yetter applicator (chisel trace disruption and soil sealing are done with one implement), additional tillage and compaction are not required. Beds may be formed following the Yetter-type applicator in a normal interval consistent to area production practices. • Tarped Applications: The use of a tarp does not eliminate the need to minimize chisel traces prior to application of the tarp, such as by using a Noble plow or other injection shank that disrupts the chisel traces. When bedding, prebedders such as ripper hippers, hillers, or other prebedders may be used to disrupt the chisel trace and seal the soil. When using equipment similar to the Yetter applicator (chisel trace disruption and soil sealing are done with one implement), additional tillage and compaction are not required. Beds may be formed following the Yetter-type applicator in a normal interval consistent to area production practices.

Soil Moisture
• The soil must be moist 9 inches below the surface. The amount of moisture needed in this zone will vary according to soil type. Surface soil generally dries rapidly and must not be considered in this determination. • Soil moisture must be determined using one of the following methods: o the USDA Feel and Appearance Method for testing (see below), or o an instrument, such as a tensiometer.
• Available water capacity must be equal to or greater than 50% for shank applications. If there is less than 50% available water capacity 9 inches below the surface, the soil moisture must be adjusted. If irrigation is not available and there is adequate soil moisture below 9 inches, soil moisture can be adjusted by discing or plowing before the start of the application. To conserve existing soil moisture, pretreatment irrigation or pretreatment tillage should be done as close to the start of the application as possible. • Measure soil moisture at a depth of 9 inches at either end of the field, no more than 48 hours prior to the start of the application.
The USDA Feel and Appearance Method for estimating soil moisture as appropriate for the soil texture: • For coarse textured soils (fine sand and loamy fine sand), the soil is moist enough (50 to 75% available water capacity) to form a weak ball with loose and clustered sand grains on fingers, darkened color, moderate water staining on fingers, will not ribbon. • For moderately coarse textured soils (sandy loam and fine sandy loam), the soil is moist enough (50 to 75% available water capacity) to form a ball with defined finger marks, very light soil/water staining on fingers, darkened color will not stick. • For medium textured soils (sandy clay loam, loam, and silt loam), the soil is moist enough (50 to 75% available water capacity) to form a ball, very light staining on fingers, darkened color, pliable, and forms a weak ribbon between the thumb and forefinger. • For fine textured soils (clay, clay loam, and silty clay loam), the soil is moist enough (50 to 75% available water capacity) to form a smooth ball with defined finger marks, light soil/water staining on fingers, ribbons between thumb and forefinger. • For fields with more than one soil texture, soil moisture content in the lightest textured (most sandy) areas must comply with this soil moisture requirement. Whenever possible, the field should be divided into areas of similar soil texture and the soil moisture of each area should be adjusted as needed. Coarser textured soils can be fumigated under conditions of higher soil moisture than finer textured soils; however, if the soil moisture is too high, fumigant movement will be retarded and effectiveness of the treatment will be reduced. Previous and/or local experience with the soil to be treated or the crop to be planted can often serve as a guide to conditions that will be acceptable. If there is uncertainty in determining the soil moisture content of the area to be treated, a local extension service agent, soil conservationist, or pest control advisor (agriculture consultant) should be consulted for assistance.

Application Depth
• Tarped Bedded and Tarped Broadcast Applications: The injection point must be a minimum of 8 inches from the nearest final soil/air interface.

Application Methods and Equipment
• Broadcast Applications: Use chisel (shank) or coulter (e.g., Yetter 30-inch Avenger), offset wing shank, Noble (sweep) plow, or plow-sole application equipment. For best results when using chisel equipment, use ripper-type, forward-swept shanks. Noble plow equipment is particularly useful for fall fumigation when the soil still contains some standing undecomposed plant material. Subsoiling may be necessary before application. Choose application equipment that allows the deepest application and best soil seal under existing conditions. o The fumigant outlet spacing varies with the type of application equipment used. o With chisel and coulter equipment, a fumigant shank spacing of 12 to 24 inches is recommended. Do not exceed the maximum shank and outlet spacing of 24 inches. The outlet spacing for this equipment may be up to 1 1/2 times the application depth but generally should be equal to the application depth and should not exceed the soilshattering capability of the chisels. o With plow-sole equipment, 12-inch outlet spacing is recommended. Do not exceed an outlet spacing of 18 inches. o With Noble (sweep) plow equipment, use an outlet spacing of 9 to 12 inches along the sweeps. o Broadcast application can be made in the same direction or at an angle to the direction of row planting.

• Bedded Applications (for Row Spacing Greater Than 24 Inches): Use chisel equipment
to treat a band of soil where the crop is to be planted, i.e., the plant row. When multiple chisels per plant row are used, space the chisels (fumigant outlets) no more than 12 inches apart. o With certain deep rooted crops such as potatoes and sugar beets, higher rates may be necessary to ensure adequate treatment of the zone of soil where primary root growth occurs; however in no case should the amount of fumigant applied exceed the maximum rate given in Table 1. o To prevent seed germination problems caused by improper seed-to-soil contact or improper planting depth, do not place the seed directly over the furrow left by the applicator chisel(s). When one chisel is used per plant row, place the seed about 4 inches to one side of the chisel furrow. When two chisels are used per plant row, plant the seed offset from the chisel trace.

Prevention of End Row Spillage
• Do not apply or allow fumigant to spill onto the soil surface. For each injection line either have a check valve located as close as possible to the final injection point, or drain/purge the line of any remaining fumigant prior to lifting injection shanks from the ground. • Do not lift injection shanks from the soil until the shut-off valve has been closed and the fumigant has been depressurized (passively drained) or purged (actively forced out via air compressor) from the system. • The dispensing system must shut off the feed stream when chisels are raised out of the ground. • Do not stop or park near any area where dribble from chisel tips has fallen.
• A flow shutoff device must be placed as close as is technically feasible to the fluid discharge point. This can be a ball, poppet, or diaphragm check valve, or full flow shutoff device such as an electric or pneumatically actuated valve. • Service any system immediately if continuous drip occurs.
• If mechanical check valves and orifices are used, place the check valve above the orifice.
Also, isolate the check valve from upstream pressure by installing a main line shut off or bypass valve prior to the manifold. • Pipe diameter from check valve to injection point must not exceed 1/4 inches ID National Pipe Standard (NPS). Preferably, use the smallest diameter pipe or tubing possible which achieves the required flow rate. • Do not use any method of end-row spillage control other than that which is stated on this labeling. • Alternative end-row spillage devices or methods, such as, but not limited to, micro-bore restricted flow tubing or line purge systems may be used if they provide equal or superior control versus check valves.

Calibration, Set Up, Repair and Maintenance for Application Rigs
• Brass, carbon steel, or stainless steel fittings must be used throughout. Polyethylene tubing, polypropylene tubing, Teflon® tubing or Teflon® -lined steel braided tubing must be used for all low pressure lines, drain lines, and compressed gas or air pressure lines. All other tubing must be Teflon® -lined steel braided. • Galvanized, PVC, nylon, or aluminum pipe fittings must not be used.
• All rigs must include a filter to remove any particulates from the fumigant and for pressurized systems a check valve to prevent backflow of the fumigant into the pressurizing cylinder or the compressed air system. • Rigs must include a flowmeter or a constant pressure system with orifice plates to ensure the proper amount of fumigant is applied. • To prevent the backflow of fumigant into the compressed gas cylinder (e.g., nitrogen, other inert gas or compressed air), if used, applicators must: o Ensure that positive pressure is maintained in the compressed gas cylinder at not less than 200 psi during the entire time it is connected to the application rig if a compressed gas cylinder is used. (This is not required for a compressed air system that is part of the application rig because if the compressor system fails, the application rig will not be operable.) o Ensure that application rigs are equipped with properly functioning check valves between the compressed gas cylinder or compressed air system and the fumigant cylinder. The check valve is best placed on the outlet side of the pressure regulator and is oriented to only allow compressed gas to flow out of the cylinder or compressed air out of the compressed air system. o A pressure relief valve must be installed between the regulator and the check valve to ensure a regulator failure does not overpressurize the fumigant cylinder. o Always pressurize the system with compressed gas or by use of a compressed air system before opening the fumigant cylinder valve. • Before using a fumigation rig for the first time, or when preparing it for use after storage, the operator must check the following items carefully: o Check the filter, and clean or replace the filter element as required.
o Check all tubes and chisels to make sure they are free of debris and obstructions. o Check and clean the orifice plates and screen checks, if installed. o Pressurize the system with compressed gas or compressed air, and check all fittings, valves, and connections for leaks using soap solution.
• Install the fumigant cylinder and connect and secure all tubing. Slowly open the compressed gas or compressed air valve and increase the pressure to the desired level. Slowly open the fumigant cylinder valve, always watching for leaks. • When the application is complete, close the fumigant cylinder valve and blow residual fumigant out of the fumigant lines into the soil using compressed gas or compressed air. If the rig uses a centrifugal pump instead of compressed gas to inject fumigant into the soil, you may clear residual fumigant from the fumigant lines using an application wand connected to the system's low point via a drain hose. Place the wand in the soil until all residual fumigant has drained from the system. The wand and drain hose must be free of dirt to allow proper drainage. At the end of the application season, disconnect all fumigant cylinders from the application rig. At the end of the season, seal all tubing openings with tape to prevent the entry of insects and dirt.
Application equipment must be calibrated and all control systems must be working properly.
Proper calibration is essential for application equipment to deliver the correct amount of fumigant uniformly to the soil. Refer to the manufacturer's instructions on how to calibrate your equipment. Usually the equipment manufacturer, fumigant dealer, or Cooperative Extension service can provide assistance.

Planting Interval
• Leave the soil undisturbed and unplanted for at least 7 days after the application of Pic-Clor 60 is complete. A longer undisturbed interval is required if the soil becomes cold or wet, and for deep-rooted tree, shrub and vine planting sites. • After fumigation to prevent phytotoxicity, allow the fumigant to dissipate completely before planting the crop. Dissipation is usually complete when Pic-Clor 60 can no longer be detected at the application depth. Under optimum soil conditions for dissipation, a period of 1 week for each 10 gallons per treated acre is generally required for complete dissipation. If tarps that qualify for either a 40% or a 60% buffer zone credit are used, a longer dissipation period may be needed. Rapidly germinating seed (i.e., lettuce or radish) and/or seed or transplants to be grown may be used as a bioassay to determine if Pic-Clor 60 is present in the soil at concentrations sufficient to cause plant injury. • To hasten dissipation especially if heavy rains or low temperatures occur during the treatment period, till the soil to the depth of fumigant application. Use a knife-like chisel without turning the soil to reduce the possibility of recontaminating the treated soil. Dissipation is usually complete when Pic-Clor 60 is no longer evident at the application depth. Seed may be used as a bioassay to determine if Pic-Clor 60 is present in the soil at concentrations sufficient to cause plant injury. Do not plant if Pic-Clor 60 is detected.

Bulk and Non-Bulk Containers
• Pic-Clor 60 must be transferred through connecting hoses, pipes, and/or couplings sufficiently tight to prevent workers or other persons from coming in contact with liquid Pic-Clor 60. • All hoses, piping, and tanks used in connection with Pic-Clor 60 shall be of the type appropriate for use under the pressure and vacuum conditions to be encountered. • Do not use containers, pumps or other transfer equipment made of aluminum, magnesium or their alloys, as under certain conditions 1,3-dichloropropene may be severely corrosive to such metals.
• External sight gauges shall be equipped with valves so that pipes to sight gauge can be shut off in case of breakage or leakage. • The mechanical transfer system must be adequate to make necessary measurements of the pesticide being used. • Shut-off devices must be installed on the exit end of all hoses and at all disconnect points to prevent leakage of Pic-Clor 60 when the transfer is stopped and hose is removed or disconnected. A dry coupler that will minimize pesticide leakage must be installed at the disconnect point. • The pressure in hoses used to move Pic-Clor 60 beyond a pump must not exceed the manufacturer's maximum pressure specification.
NOTE: In-tank cleaning of bulk tanks must be performed only by persons who have been specifically trained for this activity. Refer to OSHA 29 CFR Part 1910.146. Do not exceed specified maximum application rates in Table 1 or in the footnotes below. 1 Row treatment is not recommended for potatoes in irrigated areas of western and northwestern states. 2 For cyst-forming nematodes, increase dosage to 39 gallons product per treated acre for all applications except untarped shank broadcast. 3 For muck soils containing less than 30% organic matter use 39 gallons product per treated acre for all applications except untarped shank broadcast. 4 For mint apply 48.6 gallons product per treated acre for all applications except untarped shank broadcast. 5 For burrowing nematode in citrus, inject on 18-inch centers, 12 inches deep. Keep free of plants susceptible to burrowing nematodes for 2 years before replanting citrus. Note: To control symphylans (garden centipedes), use 38.5 to 48.6 gallons product per treated acre for all applications except untarped shank broadcast, or 24.3 gallons of product per treated acre for untarped shank broadcast applications. Apply during late Summer or early Fall when the soil is warm. To control wireworms, use dosage recommended for nematodes. For wireworm control in soils to be planted to potatoes in Idaho, Nevada, Oregon, Utah, and Washington, refer to footnote 1 above.

Calculating the Broadcast Equivalent Application Rate
To calculate the broadcast equivalent rate for bedded or strip applications the following information is needed: • pounds (or gallons) of product per treated acre • strip or bed bottom width (inches) • center-to-center row spacing (inches) • application block size (acres) Pounds (or gallons) of product per treated acre is the ratio of total amount of product applied to the size of the total area treated (e.g., the rate of product applied in the bed). For bedded or strip applications, the total area treated is the summation of the area (i.e., length x width) of each treated bed bottom or strip that is located within the application block as shown by the black areas in Figure 1 (e.g., black areas are 0.6A or 60% of the area within the application block). The area of the space between the beds/strips is not factored in the total area treated.
The application block size is the acreage within the perimeter of the fumigated portion of a field (including furrows, irrigation ditches, roadways). The perimeter of the application block is the border that connects the outermost edges of total area treated with the fumigant product.

Figure 1. Bedded/Strip Application (1 acre application block)
The "broadcast equivalent rate" must be calculated with the following formula: strip or bed bottom width (inches) Broadcast equivalent rate (pounds (or gallons) product/acre) = center-to-center row spacing (inches) x pounds (or gallons) of product/ treated acre applied in the strip or bed -The bed width must be measured from the bottom of the bed.
-The center-to-center row spacing must be calculated as shown in Figure 2.
-If there are any ditches, waterways, drive rows and other areas that are not fumigated that are in the application block, multiply the above broadcast equivalent equation by (total area of strips or beds + row spacing)/(application block size). A sample calculation is provided below.

Figure 2. Center Row Spacing
Sample broadcast equivalent rate calculation Assumptions: -Application method is shank bedded -Bed width is 30 inches (measured at the bottom of bed) -Center-to-center row spacing is 60 inches -200 pounds of product per treated acre is applied in the beds -Total application block size is 10 acres -Ditch in the middle of application block is 0.25 acres -Area of beds + row spacing is 9.75 acres strip or bed bottom width Buffer Zone Requirements A buffer zone must be established for every fumigant application. The following describes the buffer zone requirements: An area established around the perimeter of each application block.
• The buffer zone must extend outward from the edge of the application block perimeter equally in all directions. • All non-handlers, including field workers, residents, pedestrians, and other bystanders, must be excluded from the buffer zone during the buffer zone period except for transit (see Buffer Zone Exemption for Transit on Roadways). o Local, state, or federal officials performing inspection, sampling, or other similar official duties are not excluded from the application block or the buffer zone by this labeling. The certified applicator supervising the application and the owner of the establishment where the application is taking place are not authorized to, or responsible for, excluding those officials from the application block or the buffer zone. • The buffer zone period begins at the start of the application and lasts for a minimum of 48hours after the application is complete.
Buffer zone proximity • Before the start of application, the certified applicator must determine whether their buffer zone will overlap any chloropicrin buffer zone(s). Structures under the control of the owner of the application block • Buffer zones must not include buildings used for storage (e.g., sheds, barns, garages) UNLESS: 1. The storage buildings are not occupied during the buffer zone period, and 2. The storage buildings do not share a common wall with an occupied structure.
Areas not under the control of the owner of the application block • Buffer zones must not include residential areas (e.g., employee housing, private property), buildings (e.g., commercial, industrial), outdoor residential areas (e.g., lawns, gardens, play areas) and other areas that people may occupy, UNLESS: 1. The occupants provide written agreement, prior to the start of the application, that they will voluntarily vacate the buffer zone during the entire buffer zone period, and 2. Reentry by occupants and other non-handlers must not occur until, o The buffer zone period has ended, and o Sensory irritation is not experienced upon re-entry. • Buffer zones must not include agricultural areas owned and/or operated by persons other than the owner of the application block, UNLESS: 1. The owner of the application block can ensure that the buffer zone will not overlap with a chloropicrin buffer zone from any other property owners, except as provided in the Buffer Zone Proximity section, and 2. The owner of the other property provides written agreement to the applicator that they, their employees, and other persons will stay out of the buffer zone during the entire buffer zone period. • Buffer zones must not include roadways and rights of way UNLESS: 1. The area is not occupied during the buffer zone period, and 2. Entry by non-handlers is prohibited during the buffer zone period.
Buffer Zone Exemption for Transit on Roadways Vehicular and bicycle traffic on public and private roadways through the buffer zone is permitted. (NOTE: Buffer zones are not permitted to include bus stops or other locations where persons wait for public transit.) • For all other publicly owned and/or operated areas such as parks, sidewalks, permanent walking paths, playgrounds, and athletic fields, buffer zones must not include these areas UNLESS: 1. The area is not occupied during the buffer zone period, 2. Entry by non-handlers is prohibited during the buffer zone period, and 3. Written permission to include the public area in the buffer zone is granted by the appropriate state and/or local authorities responsible for management and operation of the area.
Certified applicators must comply with all local laws and regulations.
See the Posting section for additional requirements that may apply.

Buffer Zone Distances
Buffer zone distances must be calculated using the application rate and the size of the application block.
• See www.tarpcredits.epa.gov for a list of tarps that have been tested and determined to qualify for buffer reduction credits. Only tarps listed on this website qualify for buffer reduction credits. • 15% reduction in buffer zone distance, IF potassium thiosulfate (KTS) is applied at a minimum rate of 300 pounds per acre. • 15% reduction in buffer zone distance, IF ¼ to ½ inch of water is applied. • 10% reduction in buffer zone distance, IF the organic content of the soil in the application block is ≥ 1% -2%; 20% reduction in buffer zone distance, IF the organic content of the soil in the application block is >2% -3%; and a 30% reduction in the buffer zone distance, IF the organic content of the soil in the application block is >3%. • 10% reduction in buffer zone distance, IF the soil temperature is measured to be 50°F or less.
Record temperature measurements at the application depth or 12 inches, whichever is shallower. • 10% reduction in the buffer zone distance, IF the clay content of the soil in the application block is greater than 27%. • 10% reduction in buffer zone distance IF the Symmetry™ application system is used with a tarp that qualifies for a credit and the application rate is ≤ 100 pounds a.i./treated acre. The 10% credit for the Symmetry™ application system is added to the buffer zone credit for the tarp. For example if the Symmetry™ application system is used with a tarp that qualifies for a 40% credit the total credit for the tarp and the application system would be 50%.

Examples of Buffer Zone Calculations with Credits Applied
If the buffer zone is 50 feet and the application qualifies for a buffer zone credit since the soil organic content is 1.5%, then the buffer zone can be reduced by 10%, i.e., reduced by 5 feet based on the following calculation: 50 feet -(50 feet x 10%) = 45 feet.
If the buffer zone is 50 feet and the application qualifies for two buffer zone credits since the soil organic content is 1.5% and the clay content is greater than 27%, then the buffer zone can be reduced by 20% (10% organic content credit + 10% clay content credit), i.e., reduced by 10 feet based on the following calculation 50 feet -(50 feet x 20%) = 40 feet.
Posting Fumigant Buffer Zones • Posting of a buffer zone is required unless there is a physical barrier that prevents bystander access to the buffer zone. • Buffer Zone signs must be placed along or outside the perimeter of the buffer zone, at all usual points of entry and along likely routes of approach from areas where people not under the owner's control may approach the buffer zone.
o Some examples of points of entry include, but are not limited to, roadways, sidewalks, paths, and bike trails. o Some examples of likely routes of approach include, but are not limited to, the area between a buffer zone and a roadway, or the area between a buffer zone and a housing development.
o When posting, the certified applicator supervising the application must ensure compliance with all local laws and regulations. • Buffer Zone signs must meet the following criteria: o The printed side of the sign must face away from the application block toward areas from which people could approach. o Signs must remain legible during the entire posting period and must meet the general standards outlined in the WPS for sign size, text size, and legibility (see 40 CFR §170.120). o Signs must be posted no sooner than 24 hours prior to the start of the application and remain posted until the buffer zone period has expired. o Signs must be removed within 3 days after the end of the buffer zone period. o Buffer Zone signs which meet the criteria above will be provided at points of sale for applicators to use. Templates may be downloaded from http://www.epa.gov/pesticides/reregistration/soil fumigants/index.htm o The Buffer Zone signs must contain the following information: The 'Do Not Walk' symbol DO NOT ENTER/NO ENTRE, Chloropicrin/1,3-Dichloropropene Pic-Clor 60 Fumigant BUFFER ZONE, Contact information for the certified applicator in charge of the fumigation.
Exception: If multiple contiguous blocks are fumigated within a 14-day period, the entire periphery of the contiguous blocks' buffer zones may be posted. Buffer Zone signs must be posted no sooner than 24-hours prior to the start of the first application. The signs must remain posted until the last buffer zone period expires, and signs must be removed within 3 days after the buffer zone period for the last block has expired.

Restrictions for Difficult to Evacuate Sites
Difficult to evacuate sites are pre-K to grade 12 schools, state licensed daycare centers, nursing homes, assisted living facilities, hospitals, in-patient clinics, and prisons.
• No fumigant application with a buffer zone greater than 300 feet is permitted within 1/4-mile (1320 feet) of difficult to evacuate sites unless the site is not occupied by children from statelicensed day care centers, students (pre-K to grade 12), patients, or prisoners during the application and the 36-hour period following the end of the application. • No fumigant application with a buffer zone of 300 feet or less is permitted within 1/8-mile (660 feet) of difficult to evacuate sites unless the site is not occupied by children from statelicensed day care centers, students (pre-K to grade 12), patients, or prisoners during the application and the 36-hour period following the end of the application.

Emergency Preparedness and Response Measures
If the buffer zone is 25 feet, then the Emergency Preparedness and Response Measures are not applicable.

Triggers for Emergency Preparedness and Response Measures:
The certified applicator must either follow the directions under the Fumigant Site Monitoring section or follow the directions under the Response Information for Neighbors section if: • the buffer zone is greater than 25 feet but less than or equal to 100 feet, and there are residences or businesses within 50 feet from the outer edge of the buffer zone, or • the buffer zone is greater than 100 feet but less than or equal to 200 feet, and there are residences or businesses within 100 feet from the outer edge of the buffer zone, or • the buffer zone is greater than 200 feet but less than or equal to 300 feet, and there are residences or businesses within 200 feet from the outer edge of the buffer zone, or • the buffer zone is greater than 300 feet or the buffer zones overlap, and there are residences or businesses within 300 feet from the outer edge of the buffer zone. From the start of the application until the buffer zone period expires, a certified applicator or handler(s) under his/her supervision must: • Monitor for sensory irritation in areas between the buffer zone outer perimeter and residences and businesses that trigger this requirement. • Monitoring for sensory irritation must begin in the evening on the day of application and continue until the buffer zone period expires. Monitor a minimum of 8 times during the buffer zone period, including these periods: -1 hour before sunset, -during the night, -1 hour after sunrise, and -during daylight hours.
Implement the emergency response plan immediately if a handler monitoring experiences sensory irritation.
Handlers performing fumigant site monitoring outside of the buffer zone are not required to wear an air-purifying respirator. The certified applicator supervising the application must ensure that residences and businesses that trigger the requirement have been provided the response information at least 1 week before the application starts. The information provided may include application dates that range for no more than 4 weeks. If the application does not occur when specified, the information must be delivered again.

Response Information for Neighbors
Information that must be included: o The location of the application block. o Fumigant(s) applied including the active ingredient, name of the fumigant product(s), and the EPA Registration number. o Contact information for the applicator and property owner. o Time period in which the application is planned to take place (must not range more than 4 weeks).
o Early signs and symptoms of exposure to the fumigant(s) applied, what to do, and who to call if you believe you are being exposed (911 in most cases). o How to find additional information about fumigants.
The method used to share the response information for neighbors can be accomplished through mailings, door hangers, or other methods that will effectively inform the residences and businesses within the required distance from the edge of the buffer zone.

Notice to State and Tribal Lead Agencies
If your state and/or tribal lead agency requires notice, information must be provided to the appropriate state or tribal lead agency prior to the application. Please refer to www.epa.gov/fumigantstatenotice for a list of states and tribal lead agencies that require notice and information on how to submit the information.
The information that must be provided to state and tribal lead agencies includes the following: • Location of the application blocks, • Fumigant(s) applied including EPA registration number, • Applicator and property owner contact information, and • Time period that fumigation may occur.

Emergency Response Plan
The certified applicator must include in the FMP a written emergency response plan that identifies: • Evacuation routes, • Locations of telephones, • Contact information for first responders and local/state/federal/tribal personnel, and • Emergency procedures/responsibilities (e.g., adding water to the field, repairing tarps, fixing equipment, evacuating upwind) if: o there is an incident, o sensory irritation is experienced outside of the buffer zone, and/or o there are equipment/tarp/seal failure or complaints, or other emergencies.

Site Specific Fumigant Management Plan (FMP)
Prior to the start of application, the certified applicator supervising the application must verify that a site-specific FMP exists for each application block. In addition, an agricultural operation fumigating multiple application blocks may format the FMP in a manner whereby all of the information that is common to all the application blocks is captured once, and any information unique to a particular application block or blocks is captured in subsequent sections.
The FMP must be prepared by the certified applicator, the site owner, registrant, or other party.
The certified applicator supervising the application must verify in writing (sign and date) that the site-specific FMP(s) reflects current site conditions before the start of application.
Each site specific FMP must contain the following elements: List of residences and businesses informed, Name and phone number of person providing information, and Method of providing the information. • State and/or tribal lead agency advance notification (if state and/or tribal lead agency requires notice, provide a list of contacts that were notified and date notified) • Plan describing how communication will take place between the certified applicator supervising the application, the owner, and other on-site handlers (e.g., tarp perforators/removers, irrigators) for complying with label requirements (e.g., buffer zone location, buffer zone start and end times, timing of tarp perforation and removal, PPE handlers have the appropriate respirators and cartridges/canisters during handler activities, and the employer has confirmed that the appropriate respirator and cartridges/canisters are immediately available for each handler who will wear one. • If using an enclosed cab in lieu of wearing an air-purifying respirator, verify that the cab: o Has positive pressure (6 mm H 2 O Gauge). o Has a minimum air intake flow of 43 m 3 /hour. o Is equipped with activated charcoal filter-media containing no less than 1000 grams of activated charcoal. o Document the application hours of the filter to confirm that the filter has been used for no more than 50 hours of application time. o In addition document that the ventilation system has been maintained according to manufacturer's instructions. • Air monitoring plan o If sensory irritation is experienced, indicate whether operations will cease or operations will continue with use of an air-purifying respirator o For monitoring the breathing zone: Representative handler tasks to be monitored, Monitoring equipment to be used, and Timing of the monitoring.
• Pesticide Product Labels and Material Safety Data Sheets (MSDS) o Ensure that labels and MSDS are on-site and readily available for employees to review.

Record-Keeping Procedures
The owner of the application block as well as the certified applicator supervising the application must keep a signed copy of the site-specific FMP for 2 years from the date of application.
For situations where an initial FMP is developed and certain elements do not change for multiple application blocks (e.g., applicator information, certified applicator, handlers, record-keeping procedures, emergency procedures) only elements that have changed need to be updated in the site-specific FMP provided the following: • The certified applicator supervising the application has verified that those elements are current and applicable to the application block before it is fumigated. • Record-keeping requirements are followed for the entire FMP (including elements that do not change).
The certified applicator must make a copy of the FMP immediately available for viewing by handlers involved in the application. The certified applicator or the owner of the application block must provide a copy of the FMP to any local/state/federal/tribal enforcement personnel who request the FMP. In the case of an emergency, the FMP must be made immediately available when requested by local/state/federal/tribal emergency response and enforcement personnel. The certified applicator supervising the application must ensure the FMP is at the application block during all handler activities.
