Smoke From Canadian Fires May Continue to Impact South Dakota


As fires continue to burn in western Canada, smoke from the fires may continue to impact South Dakota's air quality. Weather patterns often determine how severe the impact will be. DENR encourages anyone interested in air quality levels in the state to visit DENR’s Real Time website to determine air quality levels in your area or EPA's AirNow website for predicted risks in South Dakota and the rest of the country. The state website shows real time air quality data for monitoring sites throughout the state, shows six color codes for air quality ranging from good to hazardous, and explains potential health risks for the various color coded air quality levels.

Gov. Daugaard Opposes Lower EPA Ozone Standard


Excerpts from Gov. Daugaard's comment letter (entire comment letter).


- "South Dakota opposes EPA’s proposal to lower the National Standards for ground-level ozone."


- "We are one of only seven states in the nation in which there are no nonattainment areas. The entire state is in full compliance or attainment with all federal criteria air pollutants. We are very proud of our clean air, and our goal is to maintain our clean air and that full attainment status into the future."


- "Lowering the standard now will only create regulatory uncertainty and hardship with questionable corresponding benefits to public health.  I urge you to leave the ozone standard at its current level of 0.075 parts per million."


Gov. Daugaard Comments to EPA on 111(d) Plans to Reduce Greenhouse Gases from Existing Power Plants


“South Dakota is indeed unique:

- Approximately 74 percent of South Dakota’s electric production in the 2012 base year was renewable energy (i.e., 50 percent hydropower and 24 percent wind power). The remaining 26 percent was produced from fossil fuels.

- South Dakota is a national leader in low carbon emissions; only three states emitted less carbon than South Dakota in 2012.

- South Dakota has only one coal-fired power plant and one natural gas combined cycle plant, with each plant serving different Regional Transmission Organization electric grids.


Due to the limited number of fossil fuel power plants in the state, EPA’s proposal affects South Dakota disproportionately compared to other states and leaves South Dakota with scant and inadequate options to use to meet the goal set by EPA….South Dakota recommends EPA withdraw this proposed rule and draft a rule that identifies and supports a best system of emission reductions for: coal-fired; integrated gasification combined-cycles; and natural gas fired combined cycle power plants; and that it does so for each category separately.” - from Gov.
