Current Activities and Projects

• NOTICE OF 2015 OZONE INFRASTRUCTURE STATE INPLEMENTATION PLAN. The Federal Clean Air Act requires states to revise their State Implementation Plans in response to changes to the federal National Ambient Air Quality Standards. In October 2015 EPA revised the 8-hour ozone National Ambient Air Quality Standard from 75 parts per billion down to 70 parts per billion. This action triggered the submittal of an infrastructure State Implementation Plan from each state by October 2018.

  The proposed changes to South Dakota's Ozone State Implementation Plan were open for public comment or to request a hearing on the changes through December 26, 2019. A hearing was not requested, the hearing has been cancelled, and a notice of the cancelled hearing has been noticed on South Dakota's webpage by 5:00 p.m. CST, Monday December 30 at http://denr.sd.gov/public/default.aspx.

• Revisions to Air Quality Administrative Rules. The South Dakota Department of Environment and Natural Resources (DENR) drafted revisions to several sections of Administrative Rules of South Dakota Chapter 74:36. The revisions to the Administrative Rules are being proposed to ensure DENR maintains updated rules to align with the current federal regulations. The proposed changes can be viewed here . Please respond by October 14th, 2019 to Ashley.Brakke@state.sd.us if your facility would like to submit any comments for us to consider before the rule hearing that will be held on October 17, 2019, in front of the Board of Minerals and Environment. Thank you for assisting us in this rule making process.

• South Dakota's Volkswagen Mitigation Trust website will be used to track the progress of Volkswagen's Settlement Agreement, provide an avenue for public input on the mitigation plan, and track DENR's progress in developing and implementing its mitigation plan. Round Twelve rebate recipients for the clean diesel grant program announced January 14, 2020. The program will be funded with a combination of EPA DERA funds and VW mitigation trust funds.

Applications for the VW Truck Program are being accepted for Round Two through January 31, 2020. Click here for more information.

• Clean Diesel Grant Program (Bus Replacement) Round Twelve recipients announced January 14, 2020.

• Now Available - Submit Reports Electronically: The Air Quality Program will electronically accept reports required by an air quality permit through email.  To use the email system, an acrobat copy (PDF) of the report must be attached to the email.  The acrobat copy of the report must contain the following:
  1)  The information required in the permit;
  2)  The actual signature of the responsible official; and
  3)  The following statement:  "I declare and affirm under the penalties of perjury that this claim (petition, application, information) has been examined by me, and to the best of my knowledge and belief, is in all things true and correct."
  

  If you would like to take advantage of electronic submittals, please send your reports to the following email address: AirQualityReporting@state.sd.us

  The only exception involves the annual “Operational Reports” because it is required to be notarized. Those reports still need to be submitted as hard copies.

• Interactive webpage listing facilities regulated in South Dakota under the Clean Air Act.  The webpage identifies those facilities that have a Title V operating permit or a Minor operating permit.  In addition, the webpage identifies those facilities that are applicable to a federal regulation but do not require a permit in South Dakota, which are often referred to as an area source.  Where applicable, a copy of the facility's current permit, a copy of DENR's narrative regulatory review, called a statement of basis, and DENR's most recent inspection report are provided.  Although DENR makes every attempt to ensure the information placed on this web site is accurate and current, the user should understand that the information is not guaranteed to be correct or complete.  Conclusions or actions taken (based upon the maps and the information contained therein) are the sole responsibility of the user.
