IEc developed the current versions of enforcement economic computer models under contract with the U.S. EPA Office of Enforcement and Compliance Assurance.
IEc also staffs a toll-free helpline to assist government employees in the use of the models and related financial and economic issues that arise in enforcement actions.
You may contact the helpline at 888-ECONSPT (326-6778) or via e-mail at
For cases that require more extensive assistance, especially expert reports and testimony,
IEc consultants can be retained under a variety of contract vehicles. For additional assistance
on the computer models, IEc can also be retained to provide live training courses over the Internet and in person.
Please contact the helpline to inquire about these services.
