Hower Consulting Group, Inc. was started in 2006 by Col. Ray Hower, USMC, retired. The company began by offering California Title 22 Professional Engineering (PE) assessments and certifications for hazardous waste tanks. Tank assessments often revealed a need for repairs or modifications, prompting Hower Consulting Group to manage tank system repair and modification projects for clients, which it continues to do today. Spurred by their initial success with well-documented and easy-to-follow PE certifications and assessments, the company landed its first General Services Administration (GSA) contract for Environmental Services (899-1) in 2008. Its tank engineering services quickly grew to include Steel Tank Institute (STI) tank inspections for petroleum, oil, and lubricants (POL) and hazardous materials tanks.

Before the amendments to the Spill Prevention Plan and Countermeasures (SPCC) regulation went into effect in 2011, tank owners looked to Hower Consulting Group, Inc. for assistance. Today, the company prepares, reviews, updates, and amends SPCC plans in accordance with federal and the Californian Aboveground Petroleum Act (APSA) standards. The business now encompasses all areas of hazardous waste and hazardous materials tank management, inspection, and engineering. Hower Consulting has inspected and certified over 1,000 aboveground and underground storage tanks, providing peace of mind to tank owners with the reassurance that their tanks are in compliance with local, state, and federal safety and environmental standards.
