```							National Vehicle Mercury Switch Recovery Program
SWITCH RETIREMENT MODEL
The goal of this model is to predict the number of mercury light switches available for collection from end of life
vehicles on a yearly basis.

Methodology
1) Determine the population of vehicles which may have mercury switches still on the road as of July 1, 2006
from R. L. Polk & Co. (herafter referred to as "Polk") registration data.*
2) Use adjusted mercury switch per vehicle data from Michigan Switch Study and population from step #1 to
estimate the number of mercury switches in vehicles as of July 1, 2006.
3) Use 1997 to 2006 Polk data to calculate an average scrappage rate for this period. Blend 1997 to 2006
average scrappage rate with Oakridge model for older vehicle scrappage rates. Apply the blended scrappage
rate to the number of switches calculated in step #2 to estimate the number of switches retired.
4) Calculate the estimated number of switches available for collection by subtracting inaccessible switches due
to vehicle damage, end of life vehicle exports, and lost or stolen vehicles which do not enter the recycling
stream from the numbers generated in step #3.

Data Used in Model
1) Polk registration data for Vehicles in Operation by model year and make from 1997 - 2006.
2) Michigan Switch Study data on percentage of switches found in end of life vehicles and inaccesible switches
due to vehicle damage (see http://www.deq.state.mi.us/documents/deq-ess-p2-mercury-
michiganswitchstudy.pdf for report and http://www.deq.state.mi.us/documents/deq-ess-p2-mercury-
michiganswitchstudydata.xls for data in excel format).
3) Data from Ford, GM, and Chrysler regarding which models from the 1997 MY and forward contain ball
bearing type switches (see sheets entitled "MI Data Adjustments" and "GM & Ford Ball Bearing 97 - 02" for
details).
4) Oakridge Model of Car Scrappage Rates (unpublished study by Richard L. Schmoyer, Oak Ridge National
Laboratory)
5) Vehicle export data from Census Bureau (see http://www.ita.doc.gov/td/auto/data/vehiclehistoricaldata.html)
6) Lost or stolen vehicle data from FBI Uniform Crime Report (see
http://www.fbi.gov/ucr/05cius/data/table_01.html).

The Michigan Switch Study data was adjusted in two ways.
model years were small and thus not a good indicator of switches per vehicle. The average of 1986 to 1989
data was used for this period. Since in 1973 and older models switches were phased into vehicles at an
unknown rate, these vehicles are assumed to have less switches than the 1974-1985 time period.
- An adjustment was made from 1997 to 2002 to reflect the phase out of mercury switches (some of these
switches were ball bearing switches).

Projected Mercury Switches Available for Collection from End of Life Vehicles
• The resulting projected switch retirement numbers are shown in the "50 State Summary" sheet.
• Mercury retirement rates are estimated to accurate within +/- 10% through 2017.
• Post 2017 estimates have greater uncertainty.

Future Refinements
1) The adjusted Michigan switch per vehicle data can be improved by obtaining additional data and adding it
into the data set.
2) Further study would be needed to reconcile vehicle scrappage rates from the 1997 to 2006 data with the
scrappage rates predicted from the Oakridge Model.
