Hazardous Materials Business Plans (HMBPs) and Reporting in CERS

Yorke Engineering has completed thousands of Hazardous Materials Business Plans (HMBPs) and the associated data entry in electronic reporting portals such as the California Environmental Reporting System (CERS). HMBPs are required for any facility that stores materials in quantities greater than 55 gallons for liquids, 500 pounds for solids, or 200 cubic feet for gases. We have worked with clients ranging from small private operations to large companies with many facilities. In addition, Yorke staff have worked with the local Certified Unified Program Agencies (CUPAs) in California to better understand local CUPA requirements and what they expect in HMBPs submitted within their jurisdiction. Yorke has several staff that have been working closely with CERS since its inception, and we continue to provide CERS courses at CUPA conferences. No company is more experienced with CERS than Yorke.
