State and Local Emissions Inventory System (SLEIS) Annual Emissions Submissions Due April 2, 2021

On February 8, 2021, the Nevada Division of Environmental Protection (NDEP) Air Program announced the beginning of the annual emissions reporting season for calendar year 2020. For facilities holding NDEP air quality operating permits, the State and Local Emission Inventory System (SLEIS) has been populated with each facility’s permit information as it existed on December 31, 2020 and the system is ready for data entry. NDEP has extended the deadline for reporting to Friday, April 2, 2021. 

When announcing that the system was open, NDEP noted there had been one significant change for calendar year 2020 data entry which may affect a facility’s ability to enter data. During last year’s emissions reporting process, NDEP noted that they encountered an administrative challenge maintaining SLEIS accounts for more than 500 individual facilities, including separate log in accounts for both Responsible Officials (RO) and Facility Editors (FE). As a result, NDEP is using the RO information they have on file as it existed in January 2020 and the FEs as they existed at the end of the 2019 reporting year. Check to see if your RO or FE needs to be updated.

Because of how NDEP set up the user accounts for this year’s submittal, facilities may have to go through the same process as last year to set up accounts. To maintain the security of the submittal process, NDEP is asking all RO’s to keep their security questions and answers secure and private to ensure that only the dedicated RO is in fact (1) auditing the data prior to submittal, and (2) submitting the data under the proper signature authority.
