IDEM > Compliance > CTAP: Compliance and Technical Assistance Program CTAP: Compliance and Technical Assistance Program

The Compliance and Technical Assistance Program (CTAP) is Indiana's small business assistance program (SBAP). CTAP provides free, confidential, environmental assistance to Indiana businesses. CTAP is a non-regulatory program that provides many services, but the one most frequently used by Indiana businesses is the confidential phone assistance. CTAP staff are available weekdays to answer your environmental questions regarding air, water, and waste regulations, pollution prevention, and recycling. Call CTAP today at (800) 988-7901 (in state only) or (317) 232-8172 or refer to the industry sector list for industry-specific information and assistance!

CTAP provides assistance regarding ISO 14000, which is the internationally accepted environmental management system standard that was published in 1996 and updated in 2004. CTAP offers a Quality Assurance Guarantee that IDEM will not issue a Notice of Violation assessing a gravity-based penalty against a regulated entity that has sought out, received, and relied upon CTAP’s written compliance assistance prior to the alleged violation.
