Golden State Boulevard <br />Fresno, CA 93722 <br />REVISED December 22, 2016 <br />Subject: Harvest -Lathrop facility expansion application (PA1600212) <br />Environmental Health Department has reviewed your application to expand the existing facility at 920 W. Frewert <br />Rd. and have the following comments: <br />1. Solid Waste Facility Permit, Report of Compost Site Information (RCSI), and Odor Impact Management <br />Plan (GIMP) will require revision to account for changes in operation including tonnage, accepted wastes, <br />vehicle counts, and facility size. <br />2. Track -out and drag -out has been an issue at this facility. To address this issue, all interior roads will need <br />to be constructed of asphalt or concrete except in active composting areas with rumble strips near the exit <br />of the facility. As an alternative to this requirement, facility may provide an engineered, commercially <br />constructed wheel wash near the exit of the facility. <br />3. The proposed changes include the addition of digestate. The term digestate can be used to describe digested <br />sewage sludge. The San Joaquin County Ordinance Code has a prohibition of the land spreading of sewage <br />sludge composted or other. Digestate containing sewage sludge or bio -solids is prohibited. <br />4. If in the future the facility decides to accept commercial food waste and or food digestate odor control <br />measures must be implemented. The proposed control measures shall be submitted to the EHD, for review <br />and approval prior to implementation. If the proposed control measures are not affective then additional <br />control measures must be implemented or the receipt of food shall be discontinued until such time affective <br />controls measure can be developed. <br />5. If acceptance of commercial food waste occurs at the site, the operator shall conduct a comprehensive odor <br />study to determine to odor impacts and propose alternative control measures based on the studies <br />recommendations. The odor study will need to include meteorological conditions, inversion layers, and <br />nearby receptors. The study should utilize discrete sampling and an odor panel to determine the odor units <br />created by the addition of food waste and digestate to the compost. <br />6. Offsite litter, mostly on the east side of the facility has been an issue at this facility. A litter fence will need <br />to be constructed on the east and north side of the facility to prevent litter from migrating offsite. The fence <br />will need to be a minimum of 8 feet chain link with 2 feet of barbed wire on top. The area around the <br />compost screening area shall be equipped with litter fence at least as tall as the screen (approximately 12 <br />feet in height). The litter fences can be portable. <br />7. The site is prone to ponding. The facility will need to be graded in order to ensure proper drainage. Submit <br />detailed site map noting all changes listed above. <br />Robert McClellon, REHS <br />Program Coordinator <br />
