Odor Impact Minimization Plan —Compost Facility Tracy Material Recovery Facility and Transfer Station 30703 S. MacArthur Drive, Tracy, California 95377 side of MacArthur Drive. The closest residential subdivision is approximately one mile north of the site along MacArthur Drive. Our analysis of prevailing wind conditions for the site indicates wind is predominantly from the west, which could impact the two residences northeast of the facility. However, the compost facility is located 30-40 feet below grade because it is sited within a depression from a closed gravel quarry. This tends to mitigate the transfer of odors to surrounding properties. Each day the Operator will evaluate onsite odors, especially at the northeastern site boundary between the facility and the residences, and evaluate planned operations for the potential to release objectionable odors. If the operator detects an objectionable onsite odor, he will take the following actions: 1. Investigate and determine the likely source of the odor. 2. Determine if onsite management practices could remedy the problem and immediately take steps to remedy the situation. 3. Determine whether or not the odor is traveling beyond the site by patrolling the site perimeter and noting existing wind patterns. 4. Determine whether or not the odor event is significant enough to warrant contacting the adjacent neighbors or the LEA. In the event of significant odors where a complaint has been filed, the protocol is for the Operator and/or the LEA to inspect the location of a received complaint. The Operator and/or LEA shall attempt to determine if an offensive odor exists. In the event that the complaint cannot be verified in this manner, the Operator will continue to perform self-monitoring and continue the best management practices (BMPs) described in his operating document. In the event an offensive odor is detected, the Operator and LEA shall discuss additional or enhanced BMPs to minimize the likelihood of future odor detection. The mitigation measures for windrow method would be to load out any odoriferous material to a landfill for disposal. The operator will reduce the holding time from seven days at certain times of the year where there are a high percentage of grass clippings or wet leaves to a time period which will effectively minimize odors. Section 17863.4 (b) (2) - Meteorological Data The climate in the Northern San Joaquin Valley is characterized by hot, dry summers and cool, moist winters. Most of the annual precipitation occurs as rain that falls during the winter and early spring months. Most of the rain falls during the months of November through April, with December, January, and February accounting for more than one-half of the total. 10
