10 Considerations Economics Environment Energy

11 -$s ECONOMICS +$s Collect, transport and landfill at home» OR Collect, transport, reload, transport and landfill in Southern Virginia or other State» OR Collect, reload, transport, process and sell electricity and recovered metals. Recycle residue as daily cover.

12 ENVIRONMENT: Emissions Trucks are a source of fine particulates, carbon dioxide and dioxins but are not regulated Fewer truck miles are better Landfills emit methane, 14 times more potent than carbon dioxide; Landfill leachate must be collected and treated WTE emits small amounts of emissions, these are closely regulated Health Risk Studies in Montgomery County show no elevated toxins in local fish, meat or milk. This is consistent with findings in Spain.

13 ENVIRONMENT: Land and Water Use New Landfills require 600 acres for 30 years Leachate must be collected and treated Wells must be monitored for WTE Facility uses 25 acres and last for more than 40 years New regional facility will re-cycle wastewater No leachate

14 ENERGY Central Maryland is the epi-center of electricity congestion in the Mid-Atlantic Maryland Public Service Commission report Central Maryland s transmission system is clogged like the beltway at rush hour New energy sources need to be located near homes and businesses. Electricity from the new WTE Facility will be used to heat and light schools, offices, utilities in Carroll and Frederick County and save money.

15 This map shows the hourly price of electricity in the Mid Atlantic region on July 9, 2007 at 11:55 am. The price is highest in Central Maryland because of a lack of generation and congestion in transmission.

16 ENERGY and ENVIRONMENT Over 60% of your electricity comes from burning coal When compared to electricity generated by coal, WTE facilities are many times cleaner. WTE facilities generate power for the local community

25 Residue is Treated to Meet EPA Requirements Ceramics Ferrous and Non- Ferrous Metals* Glass Heavy Metals Ashes Bowls, Coffee Cups Silverware, can lids Drinking glass, eyeglasses Light bulbs, batteries Wood ash, paper ash *Recycled

26 Outcome of Long Term Ash Landfill Study (1) The leachates do not contain dioxin/furans. The ash samples contained low levels of dioxins at less than parts per billion TEQ The soils in the vicinity of this ashmonofill, which is not covered on a daily basis, have not been affected by the air blown fugitive dust from the landfill. (1) From Municipal Waste Combustion Ash, Soil, and Leachate Characterizaiont Monofill- Cell No. III North Marion County Disposal Facility Woodburn, Oregon

27 Ash Residue Ash residue is treated to insure that it passes the Toxic Characteristic Leaching Procedure (TCLP) Test as prescribed by EPA The major constituants of leachate from landfilled ash are salts of chloride, sulfate, calcium, sodium and potassium

30 Waste-to-Energy Saves Landfill Space 13,000 KWh $900 in Revenue App. One Household for one year IN 100 cubic yards of waste (20 tons) 90% volume reduction OUT 10 cubic yards of inert ash (6 tons)

31 Increased Metals Recycling Waste-to-Energy recovers metals that are not part of the curbside recycling or drop-off program. Bike frame, eating utensils, aerosol cans, tools, oil filter, dumbbell, coat hanger, cooking pot, paint can

32 528,187 tons recycled in FY07 WTE Opens Montgomery County, MD Division of Solid Waste Services 10/17/07

33 After a moratoriam on thermal treatment, and extensive studies, the government of Sweden called low value plastics White Coal and now have 29 WTE facilities.

34 In 2004, 10 million tons of waste were thermally treated in France. The newest facility started up in downtown Paris in October, 2007!

35 The Three E s Environment: WTE facilities are highly regulated and result in reduced pollution (less trucks, less landfill, less coal) Economics: Over their lifetime, a WTE facility is less expensive than out of county landfills, and creates jobs for our regional economy Energy: A WTE facility provides a dependable source of energy in a time of rising prices.
