Helping small businesses overcome hurdles in environmental regulations.

The Compliance Assistance Office (CAO) was established within the Department of Health (DOH) in 1998 to help small businesses overcome the hurdles they face in their efforts to succeed in business while following environmental regulations. Our free and confidential services help support our mission to:

  • promote communication between the DOH and small businesses, and help distribute materials explaining regulations to small businesses;
  • intercede in disputes between small businesses and DOH;
  • promote the inclusion of small business perspectives in rule-making; and
  • work with DOH staff to increase their understanding of small businesses.


The CAO is staffed by an Environmental Ombudsman and a secretary. With such a small staff, we rely heavily on a team of staff from the various regulatory offices who have expertise in the full range of environmental topics.
