Pollution Prevention > Environmental Stewardship Program Environmental Stewardship Program

If your facility looks for opportunities to continuously improve, reduce waste and improve efficiency, reducing your footprint on Indiana's environment, then you may be an Environmental Steward.

Don't miss your opportunity for reduced recordkeeping and reporting, monitoring, inspections, and expedited and flexible permits!

Watch Gerry Dick of Inside Indiana Business as he speaks with Jean-Francois Brossoit, Plant Manager, Carrier Corporation; Tom Easterday, Senior Vice President, Subaru of Indiana Automotive; and Sam George, Vice President of Environmental Compliance, American Commercial Lines, about being members of the Indiana Environmental Stewardship Program.

What is the Environmental Stewardship Program?

The Environmental Stewardship Program (ESP) is a voluntary, performance based leadership program designed to recognize and reward Indiana regulated entities for going above and beyond current environmental regulations. In return for their exemplary environmental performance, these establishments will receive program incentives including regulatory flexibility, public recognition, and networking opportunities.

ESP focuses on improving Indiana's environment and business climate through innovation and efficient resource allocation. Participating organizations achieve environmental objectives through creating and implementing an environmental management system (EMS). Together, the EMS and the steward's commitment to continual environmental improvement will increase their efficiency, decrease environmental impacts, and may save the business time, money, and resources. Regulatory flexibility incentives earned by members were designed to provide business value, reduce regulatory oversight, allow a shift in resources from compliance driven to achieving results, and provide the member with increased operational flexibility.

Is my organization eligible?

Any regulated entity in Indiana may apply regardless of type, size, or complexity. To qualify for Indiana's Environmental Stewardship Program, applicants must demonstrate that they have:

  • A standard of environmental compliance;
  • Implemented and will maintain an environmental management system (EMS); and
  • Committed to continuous environmental improvement.

A complete description of eligibility requirements [PDF] is available.

How does my organization apply?

Once a facility has determined it meets these three eligibility requirements [PDF], the facility can submit an application for membership to IDEM. The spring application round occurs April 1 - May 31 and the fall application round occurs September 1 - October 31 each year.

Application materials are available at or by calling (800) 988-7901.

Current members who complete their fourth year may renew when they submit their Annual Performance Report in April of their fourth year.

To apply for ESP, please use the following six steps:

  1. Implement an EMS.
  2. Ensure you meet the EMS guidelines by completing the ESP EMS Checklist [PDF].
  3. Contact the ESP Program Manager at to initiate application process.
  4. Ensure your compliance history is accurately represented on U.S. EPA's ECHO database. Contact IDEM's Compliance & Technical Assistance Program at (800) 988-7901 for confidential assistance with an environmental compliance or regulatory question.
  5. Conduct an independent audit of your EMS according to the ESP Eligibility Requirements [PDF].
  6. Submit an ESP Application to the ESP Program Manager at The application, instructions, and environmental performance table are available on the IDEM Forms page (navigate down to the Office of Program Support section).

When do I submit an Annual Performance Report?

As a component of membership in the Environmental Stewardship Program, each member facility completes an ESP Annual Performance Report (APR) (available on the IDEM Forms page) in which it demonstrates to IDEM and the public its environmental accomplishments over the year, its continued high level of environmental performance, and its maintenance of the Environmental Stewardship Program membership criteria. The ESP APR must be submitted to IDEM by April 1st for each calendar year in which the entity has been a member for at least three (3) full months. Please only send an electronic version (email) of the APR. The APR includes the following:

  • A summary of the facility's EMS assessment activities and progress towards meeting EMS objectives and targets, including brief descriptions of audits conducted and improvements made.
  • A brief report on progress made in meeting the facility's environmental performance goals.
  • A summary of the facility's public outreach activities.
  • A self-certification that the facility continues to meet the Environmental Stewardship Program criteria for membership.

Please do not include any confidential business information in your ESP APR. Please keep in mind that IDEM makes the report publicly available, including posting all portions of your report on the Environmental Stewardship Program web site.

Normalizing Data

Each Environmental Stewardship Program member must normalize the data reported on the ESP Annual Performance Report. Normalization is the process of adjusting environmental performance measurements to account for increases or decreases in production over time. Normalization is important because it recognizes that facilities can become more environmentally efficient, even if total production increases. Conversely, if production declines, normalization separates out the effects of declining production from any gains in environmental efficiency.

Facilities should choose a basis of normalization that directly demonstrates changes in the activity level or output of the facility. The basis of normalization should describe both WHAT is being produced and HOW production is measured. The basis of normalization should not change from year to year, and in most cases the same basis of normalization should be used for all Environmental Stewardship Program goals. It is best to choose a basis of normalization that is measured in physical quantities using production quantities (e.g., pounds) as opposed to dollar values. For example, for an electroplating facility, an appropriate basis of normalization could be "tons of material electroplated." For a car manufacturer, an appropriate basis of normalization could be "number of cars produced."

If you have questions, please contact the ESP Program Manager at

IDEM Review of ESP Annual Performance Reports

Once a member facility submits an ESP Annual Performance Report, IDEM staff will review the report. A facility may be contacted if IDEM identifies any significant problems. It will take IDEM approximately 30-60 days to review and accept the ESP Annual Performance Reports.

Member Results at a Glance

During 2015, Environmental Stewardship Program members made the following achievements:

  • Reduced the amount of water usage enough to fill nearly 80 Olympic sized swimming pools. 1
  • Reduced the amount of natural gas used similar to eliminating CO2 emissions from 20 propane cylinders used for home barbeques. 2
  • Eliminated the amount of solid waste sent to the landfill by a weight equivalent to about 535 full-sized passenger trucks. 3
  • Saved enough electricity to power 3,715 Indiana households for one year. 4

How do I renew my ESP membership?

Facilities are asked to reapply for their Environmental Stewardship Program membership after each three (3) year membership term to ensure the facility continues to meet stringent membership requirements. To apply for an additional three (3) year membership term, current members must check the appropriate box in Section A of their third ESP Annual Performance Report and submit the full report with proof of the independent assessment to the ESP manager by the April 1st deadline. Please only send an electronic version (email) of your renewal application to the ESP Program Manager at

Facilities must have had an independent assessment of their environmental management system completed within the past thirty-six (36) months to renew membership. An independent assessment is one that is performed by someone who is neither directly employed by your facility nor someone who has played a substantive role in developing your environmental management system.

The process for renewing ESP membership is the same as the initial ESP application process. Starting April 1 of each year, IDEM has 90-days to internally review the ESP renewals (i.e., Annual Performance Report and third-party EMS assessment) for those facilities seeking to renew ESP membership. This 90-day internal review period includes reviewing the Annual Performance Reports and EMS assessments, obtaining an internal compliance history report from all IDEM program offices and, possibly, a site visit conducted by Office of Program Support (OPS) staff. IDEM management will review the compliance report, EMS assessment results, and each facility's achievements during their previous membership term. Each facility’s independent EMS assessment documents are deliberative information and will not be made public.

Facilities continuing to meet ESP program requirements will be notified of their membership renewal by the ESP program manager and will be provided with a new ESP certificate citing the newest membership term. Membership renewal notifications will be provided by the end of June each year assuming all renewing facility’s submit their ESP Annual Performance Report and EMS assessment by the April 1 deadline.
