Title V Petition 

For Part 70 permits issued in Indiana, please note the following instructions: 

The Part 70 operating permit rules provide the EPA with a 45-day review period for proposed Title V permits followed by a 60-day period in which anyone may petition the EPA to object to the permit.

• There are five basic principles

1. The 45-day review period begins the day after the proposed permit is submitted to the EPA for review; 
2. The 60-day petition period begins the day after the end date of EPA’s review period;  
3. Count every day, including weekends and federal holidays (start dates can fall on a weekend or holiday);  
4. If the end date of EPA’s 45-day review period falls on a weekend or federal holiday, the 45-day review period’s end date rolls over to the next business day. As a result, the 60-day petition period will begin the day after that next business day. 
5. If the 60-day petition period ends on a weekend or federal holiday, the petition period’s deadline is rolled over to the next business day. 

• On the Indiana Department of Environmental Management’s Air Quality Permit Status Search page, choose “Start New Search.” 
•  Select a search option from the drop-down menu to locate the permit action of interest and follow the prompts, which vary depending on the search option chosen. For example, if you search by source name, you will need to further narrow the results until you locate the permit action. If you have the specific permit number, you will be taken directly to the permit detail page. 
• On the permit detail page, under Milestone Details, locate the Start Date for Submitted to EPA. Add 105 days to that date (45-day full EPA review period + 60-day permit petition period) to calculate the deadline for submitting a petition to EPA.             

For information on the status, review dates, and petition period deadlines of a specific Part 70 permit submitted to EPA Region 5 by the Indiana Department of Environmental Management, contact one of the Region 5 contacts.
