The market for environmental health and safety outsourcing at U.S. companies is about $1 billion annually, with at least 95 percent of the U.S. market base still handling its OSHA responsibilities in-house, according to a California venture capital company.

Mission Ventures Managing Partner David Ryan gave the estimate in an announcement stating that the management at 3E Corp., Carlsbad, Calif., a provider of outsourced EHS information and services, had completed a buyout of the firm from Safety-Kleen Corp. The 3E management team, led by CEO Jess Kraus, received $25 million in financing from Mission Ventures and Frontenac Co. to complete the deal.
