materials that have undergone pathogen reduction (over 15 days), daily temperature readings will be taken. The weather conditions also play an important role. If the wind shifts toward the receptors, additional monitoring at the site perimeter will occur to detect any objectionable odors. During high wind conditions (over 25 mph), the windrow turning will temporarily cease, watering may continue as necessary to keep down dust, and incoming material will be completely tarped if it takes longer than three days to incorporate because of inclement weather conditions. Windrow turning and moisture content and odor will be evaluated when winds are over 25 mph and suspended if odor is identified at or near the property line. The piles will be watered to suppress dust and odor. If odor is still identified, a finished compost cap will be placed on the windrows to prevent odor from leaving the site. All temperature and moisture logs will be maintained on site. In addition, the logs contain information about modifications required because of weather conditions or detection of objectionable odor. The site manager, or a designee will certify each day that the measurements are true and accurate. Maintaining a clean site will prevent any unanticipated odors from occurring on the site. The areas between the windrows will be maintained to be free of any material and ponding water. Curing process and finished product The piles in the curing area and finished product areas will be kept at around 10 feet high but by the time they are at this stage, the compost should be stable and not emitting odors. They will also be inspected daily. When composting attains a characteristic of 50-60 percent solids, the material may be moved to a stabilized pile. This material, that has reached pathogen reduction, may be used to mix with incoming green and commingled material, if necessary, to reduce potential odor in the incoming material. The stabilized material may also be blended and processed to produce final products. Stockpiling of finished compost material on-site may be required for further curing and to accommodate fluxuations in the market due to seasonal weather conditions and agricultural needs. Curing provides a more mature product for applications requiring a less active material. Along with the procedures listed to control odors, additional steps eliminate: stale grass loads, ponding water around composting areas, covering of processed and unprocessed materials. Personnel Training All site personnel will be given specific training on the OIMP protocol by the site manager. Additionally, there will be a site meeting each month where the site manager will review the process and go over any issues that have arisen at the site. A record of this training will be maintained on site. 5
