manure management program (a) Definitions In this section: (1) Pasture-based management The term pasture-based management means a dairy or livestock production system in which the animals spend all or a substantial portion of their time grazing on fields in which some or all of the manure is deposited and left in the field and decomposes aerobically. (2) Non-digester dairy or livestock methane management method The term non-digester dairy or livestock methane management method means a method that may be used by operators of dairy or livestock operations to transition from wet manure handling and storage, where anaerobic conditions are present, to dry manure handling and storage, including open solar drying or composting of manure onsite, conversion of dairy and livestock operations to pasture-based management, solid separation technologies, scrape conversion, and other strategies to mitigate methane emissions from manure management, as determined by the Secretary. (3) Onsite open solar drying or composting of manure The term onsite open solar drying or composting of manure means the collection, storage, and drying of dairy or livestock manure in a nonliquid environment on a farm or ranch. (4) Scrape conversion The term scrape conversion means the conversion of flush water lagoon systems to solid-scrape or dry manure management practices, including vacuum technologies for manure management. (5) Solid separation technologies The term solid separation technologies means technologies designed to separate liquid components of manure from mineral and organic solid components, for the purposes of reducing methane emissions. (6) Eligible producer The term eligible producer means a dairy or livestock producer whose baseline manure management practices prior to enrollment in the program include the anaerobic decomposition of volatile solids stored in a lagoon or other predominantly liquid anaerobic environment. (b) Establishment The Secretary shall establish an alternative manure management program to support non-digester
