RE: Proposed Area Designations for the 2008 revised Lead Standard 

Dear Ms. Rushin: 

Thank you for your letter asking Governor Rounds to provide the Environmental Protection 

Agency (EPA) with recommendations for designation of areas of the state for the October 15, 

2008 revised lead National Ambient Air Quality Standard. Governor Rounds has delegated 

the authority to determine and submit designations for South Dakota to the Secretary of the 

South Dakota Department of Environment and Natural Resources (DENR). Therefore, I am 

submitting the proposed designations on the Governor's behalf. 

As provided by Section 107(d) (l) (A) of the Clean Air Act, I propose that all counties in 

South Dakota be designated in attainment for the 2008 revised lead standard (See Attachment 

1). I propose the designations for the following reasons: 

•	 DENR reviewed 2008 Toxic Release Inventory report of air quality emission. Data
 

received from the facilities in South Dakota in the 2008 Toxic Release Inventory
 

report shows that all facilities have yearly emission of less than one ton of lead per
 

year. Therefore, the potential to exceed the national standard remains low from
 

facilities in the state (See Attachment 2).
 

•	 DENR reviewed past air monitoring data collected in the state to determine proposed
 

county designations. Two types of air monitoring data were found in the EPA Air
 

Quality System data base for lead. The first type was lead concentrations analyzed
 

from total suspended particulates samples. The reported quarterly lead averages are all
 

less than the revised standard. Following the removal of most of the lead from gas and
 

because the potential was low for finding lead concentrations greater than the national
 

standard, the DENR closed down the last lead monitoring site in 1994.
 
•	 The second type has data from PM2.5 samples analyzed for lead concentrations taken 

in the Badlands and Wind Cave National Parks and the PM2.5 speciation sampling site 

in Sioux Falls, South Dakota. Lead concentration analyzed from the PM2.5 samples 

provide a good indicator ofpollution coming from combustion sources. All sample 

concentrations reported in the EPA Air Quality System database are less than the 

revised lead standard. 

•	 Air quality emissions of lead are low in South Dakota. During the years when leaded 

gas was sold, DENR operated monitoring sites testing for lead concentrations. None 

of the data collected in those years exceeded the lead standard. The combination of 

the state's low population, small number of facilities, and low lead emissions from 

those facilities keeps the ambient air quality concentrations below the lead standard. 

Currently, the only testing for lead concentrations is the chemical speciation of PM2.5 

samples collected at the Badlands and Wind Cave National Parks and a site in Sioux 

Falls. 

Thank you for allowing South Dakota to propose designations for the 2008 revised lead 

standard. If you have questions on this notice, please contact Brian Gustafson at 605-773­

3151 for more information.
