In addition to these emissions a second simulation was performed on the impacts to air quality from on-site vehicles and equipemt used at the transfer station. This is based on the equipment list previously mentioned and assumes the following for the base year 1990. 1) light equipment moves at 10 mph and operates for eight hours 2) heavy equipment moves at 5 mph and operates for eight hours 3) fined equipment in the plant operates eight hours. The computer program AQAT-3 estimated the following on-site emissions in pounds per day. TOG 107 ROG 98 CO 382 NOx 246 All particulates 114 Sox 32 For the existing condition, taking into account both the emissions from traffic coming to the transfer station and the emissions of vehicles and equipment at the site, the following total emissions were estimated as follows: TOG 137 ROG 126 CO 631 NOx 317 All particulates 121 Sox 39 Provosed Expansion Assuming the proposed expansion takes place, the additional equipment which will be used in the 89,000-square-foot building will include a new bailer for recyclable materials, an Amfab refuse compactor, material sorting conveyors, a wood sorting conveyor, and a wood grinder(See page 5). Equipment for composting and rock rubble recovery will include a rock and rubble crusher and associated processing equipment, and a compost aerator (Scarab) and screening equipment. Additional equipment which will be parked, maintained, and used to operate the facility is listed on page 6 and totals 124 pieces of equipment projected for use by the year 2000. For pollutant estimates for the expanded transfer station, it is assumed that 50% of the waste stream is recycled, meeting the goals of AE 939, compared to the existing 20% of the waste stream. Additionally, the waste stream is assumed to total 3,250 TPD portioned into 1,625 TPD recycled and 1,625 TPD of waste hauled to the disposal facilities. Vehicles used in this scenario are shown hereunder: 21
