i The operator needs to list (and consider) ail feedstock received. Many compostable materials have very distinctive odor -generating properties. Descriptions that contain the type and source of the material are especially helpful; such as, "two week collection cycle, curbside green material," or "private hauler, landscraper-collected, yard trimmings," or "morning -delivered, by end -dump, 95% moisture biosolids," or "unground, grocery produce with associated packaging by walking -floor trailer." ii Compostable materials used on-site for beneficial use are generally considered removed from the site. iii The distribution of receptors and their relationship to surrounding land use is extremely important. The description of surrounding land uses may also assist in identifying other potential odor sources. iv An odor complaint receipt procedure is an integral part of the GIMP. The information provided by the complainant can be extremely valuable to site operations personnel. A typical odor response protocol might be: When a complaint is received, designated site personnel will: 1. Obtain time, location, and nature or characteristics of the odor and record that information to review for operational trends (see 4.). 2. If practical, proceed to the location of the complaint to verify that the site is indeed responsible for the odor. Otherwise, investigate the probable source of the odor complaint and implement operational changes to minimize odors. 3. If warranted, meet with the LEA and complainant (if known and choosing to participate) within a reasonable time frame to discuss the nature of the source of the odor and operational changes proposed and/or implemented. 4. Document the complaint(s) in the Operations/Complaint Log, including the nature of the complaint Odors generated after turning Increase turning frequency, increase pile porosity, add odor -absorbing amendment (like wood chips, sawdust, wood ash) Long retention time Remove chipped and ground material more frequently Curing Piles/ Product Storage Odors present at time of loading Decrease pile size, increase Area (temperatures above 122 °F) windrow time prior to moving to curing piles or product storage i The operator needs to list (and consider) ail feedstock received.
