PAR 1133.1 would establish the best management practices (BMPs) for chipping and grinding activities, including stockpile operations, to produce materials other than active or finished compost material. PAR 1133.1 would establish requirements for processing, utilizing or removing greenwaste from the site within 48 hours of receipt, unless otherwise allowed by the Local Enforcement Agency to hold for a longer period of time. PAR 1133.1 would apply to any chipping and grinding activities to produce materials other than active or finished compost, occurring at a chipping and grinding facility, a material recovery facility (MRF), a landfill using this material for alternative daily cover (ADC), a transfer station, a biomass power generation facility, or a composting facility. PR 1133.3 would implement Control Measure (CM) MCS-04 of the 2007 Air Quality Management Plan (AQMP) and seeks to establish operational BMPs for greenwaste composting operations that produce active or finished compost material from greenwaste-only or greenwaste in combination with manure or foodwaste. Operators of greenwaste composting operations would be required to apply finished compost cover after the initial pile is formed and up to the minimum of seven days and water irrigation within a specified time before turning the material for all active phase piles. Additionally, for greenwaste composting operations processing greenwaste mixed with greater than 5,000 tons per year of foodwaste throughput, the operator would be required to install an emission control device for all active phase compost piles containing foodwaste content of 10% or more by weight. PR 1133.3 would apply to greenwaste composting operations involving organic waste materials, including greenwaste, woodwaste, manure, or foodwaste.
