6. Meet with the LEA and complainant (if known and choosing to participate) after action is taken to assess the success of the action(s) to minimize odors in the future. 7. Document the actions taken and results in the Site Operations Log and Special Occurrences Log. A sample Odor Complaint Form is provided in Appendix A. 3.0 OPERATING PROCEDURES AND DESIGN TO MINIMIZE ODORS In order to minimize the development of conditions that could lead to odor problems, the compostable material handling areas of the site were designed based on the nature and quantity of materials to be received and stored, climatological factors, adjacent land use, grading, and drainage controls. The Compost Facility uses the windrow composting method turned using a windrow machine. Odor generation at composting facilities tends to fluctuate, rising at the start of composting and dropping quickly. Proper management and the location and storage of materials minimize the development of conditions that could lead to off- site odor nuisances. It should be noted that all incoming loads are required to be covered with a tarp(s) or mesh when entering and existing the facility (assumed Carped during transportation of waste). They should only untarp and tarp at the working area. This tarping policy is strictly enforced (see Litter Management Plan). In addition, on-site containers utilized to store waste and/or feedstock are also covered to mitigate odors. In addition, Forward has recently planted poplar trees along the eastern and western boundaries of the RRF. The trees are expected to grow at a rate of approximately 7 feet per year to a total height of approximately 60 feet and are spaced sufficiently close to provide an effective barrier along the perimeter. Forward felt the trees would be more aesthetic, limit dust transport, and act as a barrier for litter, as well as allow for air mixing and odor dispersal. 3.1 AERATION Aeration is necessary for odor control. Maintaining the oxygen level at approximately 5 to 15 percent inside the compost pile minimizes odors. 3.2 MOISTURE CONTENT OF MATERIALS AND MOISTURE MANAGEMENT The specific mixtures for composting are developed based on the availability of feedstock, desired use of the product and the operating parameters required for proper composting. The material received is listed in Section 1.0 as allowed under 14 CCR, Section 17852. Composition and residual moisture of the materials is dependent on the source of the feedstock and time of year. Acceptance of these wastes depends on having sufficient dry compost feedstock to absorb excess water. Water from these sources is used to replace use of on-site water to create initial compost mixture moisture content within the desired range. The desired moisture content for composting mixtures for optimum composting and minimum odor generation are as follows: Forward Compost Facility-OIMP 5 SWT Engineering z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2013-14\tpr 2014\appendices\app a-3-oimp\oimp text-rev 111414.doc;11/18/2014
