Don’t forget to assess your air emission levels before paying your facility’s 2017 Annual Registration Fee for the Illinois Environmental Protection Agency’s Registration of Smaller Sources (ROSS) program.
By paying your 2017 annual registration fee, you are renewing your registration and verifying that your source’s calendar year 2016 actual emissions meet the criteria under the Registration of Smaller Sources (ROSS) Rule 35 Ill. Admin. Section 201.175. Emission criteria include:
Actual emissions from the source’s emission units are less than the following limits for the prior calendar year*:
- 5.0 Tons/yr of combined pollutants (particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide and volatile organic material)
- 0.50 Tons/yr of combined Hazardous Air Pollutants (HAPs)
- 0.05 Tons/yr of mercury air emissions
- 0.05 Tons/yr of lead air emissions
*Do not include emission units that are exempt from the permitting requirements and can be found at 35 Ill. Adm. Code 201.146 or the publication Does My Business Need An Air Pollution Control Permit? in your in actual emissions calculations.
If your actual emissions have exceeded the calendar year limits, you must either apply for a permit pursuant to (35 Ill. Admin. Section 201.175g) or if your source was previously permitted and still meets the terms and conditions of the previously issued permit under 35 ILCS Section 201.169 , you must notify the agency of your change in status from a ROSS eligible source to a permitted source within 90 days of the source’s annual fee payment date.
Tools to assist with emission calculations for some common ROSS eligible industries can be found here.
Your source’s annual fee payment date is based upon the date source’s initial air permit or registration was approved.
