3-13 Forward Composting Facility SWT Engineering Report of Composting Site Information - January 2022 Rodents and Insects. The Compost Facility/RRF receive s minimal quantities of wastes that may attract rodents and ins ects, thus minimizing the food and habitat. In addition, timely removal of the wastes, and keeping the storage of waste to within 24 hours of receipt, minimizes the attraction and presence of rodents and insects. As mentioned above, Forward has a professional pest management company on retainer for advice and services, as needed. Insects have not been a nuisance at the site. Typical high temperatures maintained in the active compost are sufficient to kill pathogens, insect larvae, and insects. Birds. Due t o the site’s proximity to the Stockton Metropolitan Airport, Forward implements an aggressive bird control program which incorporates falconry and pyrotechnic based techniques. Nuisance birds will also be controlled by reducing litter through the litt er collection program. Recordkeeping . Records of monitoring and any corrective measures taken to address infestations, should they occur, are maintained at the RRF/Compost Facility. 3.6.2 Odor Control Odors at the Forward Landfill facility was evaluated in the Supplemental Environmental Impact Report (SEIR) for t he Forward, Inc. Landfill 2018 Expansion Project (Grassetti Environmental Consulting, 2019). Mitigations are detailed in the SEI R and include implementation of the Odor Control Impact Minimization Plan. Odor generation at composting facilities tends to flu ctuate, rising at the start of composting and dropping quickly. Prevention is the most desirable form of odor control. Process monitoring of composting conditions, especially aeration, is necessary for odor control. Research suggests that maintaining th e oxygen level at 5 to 15 percent inside the compost pile, controlling the moisture content, and maximizing the decomposition ra te will serve to minimize odors. In general, odors are controlled by processing the wastes and removing them as soon as possible after they have been brought into the RRF. Facility personnel conducts daily odor inspections at the RRF. As discussed in 3.3 .4, housekeeping activities are conducted on a continual basis. Odor control procedures are implemented to prevent odor impacts . Efforts to prevent and reduce odors will include: ⧫ Avoiding creating large stockpiles of incoming material ⧫ Producing a homogeneous material with the proper moisture content ⧫ Providing adequate aeration and agitation ⧫ Incorporating careful control of proces sing temperatures to maintain the rate of decomposition. Additionally, as required in 14 CCR, Sections 17863.4 and 18227(n), an Odor Management Plan (OMP) is included as Appendix E-1. Odors are not anticipated from residue storage since residue will be st ored for no more than 24 hours. If persistent odors are produced, additional odor control techniques that may be implemented include: ⧫ Maintaining a carbon-to-nitrogen (C:N) ratio above 25:1 in initial mixes of high nitrogen materials;
