Emissions Inventory

Overview

The USEPA requires States to inventory and submit emissions from air pollution sources. These sources include Point Sources (industrial stationary sources), Nonpoint Sources (small facilities, lawn mowers, wood stoves, etc.), and Mobile Sources (cars, trucks, boats, etc.). Only the Po​int Source emissions are required to be reported to the USEPA every year. Nonpoint and Mobile sources are reported every three years. The most recent comprehensive three-year inventory was for the 2017 calendar year.

Inventory data is used to verify whether air programs previously enacted are being effective and to aid in designing air programs needed to ensure air quality is improved or maintained. Additionally, for new rule development, the USEPA uses these emissions estimates to model the risk to nearby communities; especially for toxic air pollutants.

SLEIS Database

West Virginia uses the State & Local Emissions Inventory System (SLEIS) database software to collect the Title V point source emissions.

  • SLEIS Database

    State & Local Emissions Inventory System

  • SLEIS Registration Forms

    To use SLEIS, an account must be established. If you are not registered, please download, save, and complete the registration form from the SLEIS application and email the completed form to dep.aei@wv.gov.

Required Documents

  • Declaration of Data Confidentiality

    Date: October 30, 2013
    Use to describe Confidential Business Information (CBI) in the Emission Inventory submittal. Do not put confidential information in the SLEIS submittal. Confidential data is to be submitted separately. If not claiming data confidential, put an "X" in the box labeled "Check here". Copy the completed table and attach it to your SLEIS emission inventory submittal.

  • Title V Cross Reference Table

    Date: October 30, 2013
    Use to reconcile differences between Title V and SLEIS numbering schemes. If the numbering schemes match exactly, submit with an "X" in the box labeled "Check here". Copy the completed table and attach it to your SLEIS emission inventory submittal. You must submit this spreadsheet every year, even if one was submitted for a prior year.

  • Certification of Data Accuracy

    Date: November 17, 2017
    This document cannot be submitted as an attachment in SLEIS, as it requires a confirmation number that will not be available until AFTER the SLEIS inventory has been submitted.

Document Submission

The Declaration of Data Confidentiality and Title V Cross Reference table spreadsheets must be completed and sent as attachments via SLEIS or submitted via email. The Certification of Data Accuracy must be printed, completed, and submitted on paper as it requires a signature and confirmation number that is unavailable until after the SLEIS inventory has been submitted. You may scan and email the completed Certification of Data Accuracy or print and submit it through postal mail.
