t Purpose/Context of the OIMP This Odor Impact Minimization Plan (GIMP) provides guidance to on-site operations personnel for the components of this Plan, in accordance with Title 14, California Code of Regulations Section 17863.4. The operator will implement and maintain this OIMP. The facility will be able to implement all required procedures required. The facility is a windrow composting facility receiving urban green material, agricultural residues, and food scraps. The resulting material is sold to landscapers and agricultural operations as organically certified compost. The facility receives a maximum of 500 tons per day and 156,000 tons per year of combined feedstocks into the facility. All feedstocks are processed and incorporated into windrows within 72 hours of receipt. No material will remain on site for more than six months, but most finished compost and other material is sold and/or removed from the site within one to three months depending on seasonal and climatic conditions. Odor Monitoring Protocol The composting facility is located in an agricultural area with scattered residences. Since facility staff are the closest to the composting operations, they will be the first to assess the odor impacts on and off site. Each day, the site operator, or designated employee, will investigate if there is any off-site odor by walking the perimeter of the property between 7 a.m. and 9 a.m. each morning. As a result, the operator will determine if additional management measures are required. If objectionable odor is identified by the site operator, the following monitoring protocol will be followed; 1. Investigate and determine the likely source of the odor; 2. Determine if on-site practices can minimize the odor; if so, implement immediately; 3. Determine if significant odor is traveling beyond site boundary and note wind direction 4. Determine whether odor event is significant enough to contact LEA/ or neighbors; and 5. Record event with date, time, wind direction, location and action taken in the Site Operations Log. If it is determined that odor has moved off-site, the following general steps will be followed and specific protocols detailed in the Operational Procedures section will be implemented. • Identify the source of the odor • If odor is in the processing/grinding area: o Mix the material with non -odorous compost or carbonated organics o Cover the material with additional wood chips, compost or tarp if necessary o Mist the material to prevent odor from spreading • If odor is in the windrow area: o Oxygenate the windrows by mixing with the windrow turning machine; o Check to see if aisles are clear of material and ponding water and correct if necessary; and
