Chapter 2 - Section IV: Public Comment

  • What is public comment?
    • Prior to making final decisions about certain permits or actions, state law requires IDEM to provide time for the public to submit comments. A public comment period is held to allow time for interested parties to submit questions, opinions, or concerns about agency actions. Comments can be in favor or against an action.
  • How can the public submit comments?
    • The public may mail written comments to IDEM at the address provided in the public notice.
    • The public may provide oral comments by speaking at a public hearing, where all statements are officially recorded.
    • The public may submit written questions and comments during public meeting or information sessions. Oral questions and comments may not be officially recorded during informal meetings or information sessions.
  • When can the public submit comments?
    • Public comments should be submitted during the official public comment period. Public comment periods are usually between 21 and 45 days. The length of time will be detailed in the public notice.

What is a public comment?

Public comments can be questions, opinions, concerns or information concerning an issue, activity or project. Prior to making final decisions about certain permits or actions, state law requires IDEM to provide time for the public to submit comments.

What is the purpose of a public comment?

IDEM protects Hoosiers and their environment. As a Hoosier, you have a right to be involved in decisions that may affect you. A formal public comment period offers you the opportunity to do just that. The purpose of the public comment period is to allow any member of the public to add their voice to the decision-making process.

How long does a public comment period last?

The length of the public comment period will be stated in the public notice. Most IDEM public comment periods are for 30 calendar days, beginning with the day after the public notice first appears. If the 30th day of a public comment period falls on a weekend day, state holiday, or other day when state governmental offices are closed, then the public comment period will end on the close of the next day on which state offices are open for business. Although most IDEM public notice periods are for 30 days, some comment periods can be as short as 21 days, and others as long as 45 days. Comment periods are often determined by state or federal rules or requirements.

Upon request, some IDEM programs holding public comment periods may agree to extend the public comment period beyond 30 days. Such extensions, when granted, generally add an additional seven to 15 days, during which public comment will be accepted. Again, it is left to the particular program area (air, water, or waste) whether to grant an extension, and the length of the extension generally varies from program to program. In addition, the person seeking an extension may be required to demonstrate why the extra time is needed. Such requests must be made through the contact person listed in the public notice.

If IDEM agrees to a request for a formal hearing either during or after the public comment period, IDEM may extend the public comment period or an additional comment period may be held in association with the hearing. The opportunity to submit comments also may be extended for a few days after the hearing in order to give persons who attended the hearing, or who learned new information at the hearing, additional time to submit comments.

How can you comment on environmental rules or permits?

Preparing to comment

Knowing specifically when to get involved in IDEM’s rulemaking and permitting processes is easy if you have the tools you need. The more information you have on a particular activity or a facility that might be proposed in your community, the more informed you can become about regulations prior to commenting. IDEM provides multiple avenues for reviewing permit documents and learning more about environmental protection efforts in Indiana through a number of Internet resources and through IDEM’s Central File Room.

Legal Resources

Indiana’s environmental regulations are available for the public to review, as are our federal environmental regulations. Following are links for Indiana’s environmental statutes (found under the Indiana Code), Indiana’s administrative rules (found under the Indiana Administrative Code), as well as other state and federal resources.

How to comment

You may comment in favor, voice opposition, raise questions, or share concerns about how a proposed activity could affect you, your family, and your neighborhood or the environment. You may take the opportunity to request that certain requirements or conditions be included in a permit. Regardless of your position, permit decisions are more likely to be influenced by factual comments that reference specific laws, rules, and regulations, technical or scientific information, or information about special considerations at a proposed site. In addition, comments need to address the issue described in the public notice. Public notices provide instructions for submitting written comments to IDEM. Where IDEM holds formal public hearings, oral (spoken) comments are accepted in addition to written comments.

Written comments

To submit a public comment, simply put your thoughts in writing and submit them to the address provided in the public notice. Written comments also may be submitted during a public hearing or public meeting, if one is being held. If you do need wish to attend a scheduled public hearing or meeting, all can participate simply by mailing your written comments to IDEM, per the instructions of the public notice.

Oral comments

Members of the public may present comments orally, if they wish to, during formal public hearings. An official transcript of the hearing is prepared and included in the public record. To ensure an accurate record of all oral comments, however, individuals who wish to speak at public hearings typically are also asked to submit a written copy of their comments. While many public meetings provide an opportunity for the public to speak, an official transcript is not maintained.

When can you comment?

Public comment periods

Certain permitting decisions and other actions require an official public comment period: in those cases, the agency works in a number of ways to notify the public about the dates comments will be accepted, the address for mailing or delivering written comments, whether a public hearing has been scheduled, and contact information for a staff person who can answer questions from the public. Where public participation is not legally required but there is significant public interest, IDEM may work in a number of ways to keep the public informed and enable interested parties to provide feedback. For more information, see “How are public notices issued,” under Section II on Public Notices in this Chapter.

Public hearings

A public hearing is a formal proceeding that provides the public with the opportunity to submit written and oral comments in a formal setting. Formal official public meetings involve a court reporter or tape recorder documenting all questions and comments. A hearing officer presides over hearings and following a hearing, the court reporter prepares a hearing transcript. IDEM makes the hearing transcript, with responses, available to the public announcing the final decision on a proposed action. Where public hearings are not automatically required, there may be the opportunity for the public to request one. In such cases, IDEM will carefully weigh the issues and make a final determination about whether a formal hearing will enhance public participation.

Public meetings

Public meetings are informal meetings with the public during which IDEM staff present information and answer questions about a proposed action. A public meeting promotes dialogue and discussion, and permit staff try to respond directly to questions from the public. Oral questions and responses are informal at a public meeting. IDEM does not document or provide written responses to questions and comments addressed during a meeting. However, the public may submit written comments during a public meeting or at any point during a public.

In some cases, an informal public meeting will be held immediately before a public hearing, to allow permit applicants and/or IDEM staff to present information and help answer questions in a group setting.

Public availability sessions

A public availability session is the least formal meeting setting. Designed like an open house, staff will provide and be available to discuss literature, maps and documents one-on-one with the public.

Special accommodations
