sary. In this case, regular inspection and monitoring of the site will be conducted by the San Joaquin County Health Services Department. Rodents and Insects. The Compost Facility/RRF will receive minimal quantities of wastes that may attract rodents and insects, thus minimizing the food and habitat. In addition, timely removal of the wastes, and keeping the storage of waste overnight to a minimum, minimizes the presence of rodents and insects. Forward has a professional pest manage- ment company on retainer for advice and services, as needed. Insects have not been a nuisance at the site. Birds. The site mainly accepts wastes which do not attract birds. The majority of waste handling activities are done in the RRF building. The wood chipping operations are con- ducted outside but are not attractive to birds. Under normal operations, wastes are pro- cessed within 24 hours. Additionally, nuisance birds will be controlled by reducing litter through the litter collection program. 2. Odor Control Describe procedures to identify and prevent odor nuisances. Odor generation at composting facilities tends to fluctuate, 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 the oxygen level at 5 to 15 percent inside the compost pile, controlling the moisture content, and maximizing the decomposition rate will serve to minimize odors. In general, odors are controlled b processing the wastes and removing them as soon as g YP g g possible after they have been brought into the RRF. Odor control procedures will be im- plemented 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 processing temperatures to maintain the rate of decomposition. Odors are not anticipated from residue storage since residue will be stored for no more than 48 hours. If persistent odors are produced, additional odor control techniques that may be implemented include: • Maintaining a carbon-to-nitrogen ratio above 25:1 in initial mixes of high nitro- gen materials aea10029M.wp5/69 9/29/94 69
