3 COUNTY OF SANTA BARBARA OFFICE OF THE AGRICULTURAL COMMISSIONER SANTA BARBARA SANTA MARIA LOMPOC SOLVANG CARPINTERIA 2011 Application for Shank Applied Metam Sodium/Potassium Use PERMITTEE CONTACT NAME PERMIT NUMBER PHONE NUMBER SITE ID ACRES APPLICATOR CHEMICAL & RATE Please provide the following information about the water source used to provide water for odor mitigation. Or, check here if you are more than one mile from a school and more than ½ mile from an occupied structure or bystander area. Water Source Capacity in gallons/minute Number of acres per sprinkler irrigation set How many post-application water treatments will be made? Will you have exclusive use of the water source during the time of odor mitigation (during application and 48 hours after)? Definitions Odor Mitigation Water Source The term occupied structure is defined to include, but is not limited to, a home or other building that may be occupied for any or all parts of a 24-hour period. An occupied structure does not include buildings where people may visit for limited periods of time such as barns, equipment sheds, pump houses and workshops. However, people must not be directed or allowed to work in any structure within the buffer zone if odors are detected in the structure. The term bystander area is defined as an area used or visited by people on a daily basis, including parks, playgrounds, lakes, reservoirs, bus stops, and other similar areas where groups of people visit, or other areas identified by the CAC. The term application block is defined as a field or portion of a field fumigated in a 24-hour period. Rev

4 The permit applicant shall provide a map of the area to be treated that includes the surrounding area for a radius of 1 mile. The diagram must include the location of schools, occupied structures, bystander areas and the water source used for odor mitigation. Include distances of schools, occupied structures and bystander areas from the treatment site. Indicate application blocks. N Rev

5 Accident Response Plan What to do in case of accidental spill or release of the fumigant Employees who work with the fumigant must be trained in the procedures to follow in case of an accidental spill or odor problems. If the release or threatened release poses a significant present or potential hazard to human or environmental health and safety call and County Fire/Hazardous Materials Emergency Contact Information (Fill in names and phone numbers for your company) Evacuate personnel from the leak or spill area. Shut down the application system to stop the leak or spill. If possible, determine wind direction and move personnel and anyone injured upwind an away from the impacted area. Establish control of the area. Immediately administer first aid to anyone who may be injured and contact the appropriate emergency personnel by dialing Emergency PPE must be readily accessible at all times. Wear emergency PPE and clothing required by the label when assisting with repair of leaks and small spill clean ups. For large spills, see below. For small leaks from application and chemigation equipment, put a container under the leak and catch the leaking material. Turn off any equipment valves that may affect the leak. Repair the leak. Return caught material to tank or dispose of properly. Clean up the contaminated area. For small spills, contain the material. If puddles are present, clean it up with absorbent material and dispose according to appropriate local, state and/or federal requirements. If the soil is contaminated, determine whether removal is necessary. If contaminated soil must be removed, dispose contaminated soil according to appropriate local, state and/or federal requirements. For large spills, notify HazMat or Fire Department personnel immediately. If properly trained in HazMat responses, wear appropriate PPE (chemical resistant suit, gloves and boots, and selfcontained breathing apparatus). Dike the area to prevent spreading and further environmental contamination. If metam sodium or metam potassium has pooled within the dike area, then use a tank truck with vacuum hoses to remove it. Remove and dispose the contaminated soil according to appropriate local, state and/or federal requirements. The plan may include the assistance of an environmental service company that could provide support in large spill emergencies. Notify the appropriate personnel. County Fire Protective Services Division ( ) has a Hazardous Materials Incident Reporting Guide that will assist you with your incident reporting obligations to local agencies. Rev

9 Buffer zone tables Buffer zones are determined by the application time, pounds of active ingredient per acre, the number of acres, and the number of post application water treatments. When fumigating multiple blocks, the buffer zone is calculated by adding the acreage of blocks fumigated within any 2 day period when they are within ¼ or less apart. Table 1: Metam sodium and metam potassium buffer zone values for shank applications with three post-application water treatments ¹ Application rates are expressed for broadcast applications, and were calculated for metam sodium applications. To determine buffer zones for metam potassium applications, multiply the buffer zone distance listed by 0.9.

10 Table 2: Metam sodium and metam potassium buffer zone values for shank applications with two post-application water treatments ¹ Application rates are expressed for broadcast applications, and were calculated for metam sodium applications. To determine buffer zones for metam potassium applications, multiply the buffer zone distance listed by 0.9.

11 Table 3: Metam sodium and metam potassium buffer zone values for shank applications with one post-application water treatment ¹ Application rates are expressed for broadcast applications, and were calculated for metam sodium applications. To determine buffer zones for metam potassium applications, multiply the buffer zone distance listed by Not Allowed.
