City of Morgan Hill Hazardous Materials Facilities

Last modified: 12/18/2012 3:27 PM
Effective January 1, 2013, the Santa Clara County Fire District will no longer be a Participating Agency within the Unified Program in the City of Morgan Hill.  Santa Clara County Department of Environmental Health (DEH) will be responsible for implementing the Underground Storage Tank (UST) program and the Hazardous Materials Business Plan (HMBP) program within the City of Morgan Hill.   The remaining four State Environmental programs have been, and will continue to be, implemented by DEH within the City. The following is a complete list of the environmental programs that make up the Unified Program:

• Hazardous Materials Business Plan (HMBP) Program
• Underground Storage Tank (UST) Program
• Hazardous Waste Generator Program
• Hazardous Waste On-Site Treatment Tiered Permit Program
• California Accidental Release Prevention (Cal ARP) Program
• Aboveground Petroleum Storage Act (APSA) Program

Due to the rapid transition of the programs, DEH will not invoice for UST and HMBP permits that expire in January.  DEH will invoice for these permits in March.  During this period DEH will coordinate with the City to ensure that your permit and invoice are as accurate as possible.

Frequently Asked Questions (FAQ) 
What has changed? Effective January 1, 2013, Santa Clara County Fire District will cease being a Unified Program Agency (UPA) within the City of Morgan Hill and will give up the Hazardous Materials Business Plan (HMBP) and Underground Storage Tank (UST) programs in that city. Santa Clara County Department of Environmental Health (DEH) will now have sole responsibility for permitting, inspection, and enforcement of those programs in addition to the hazardous waste generator, hazardous waste tiered permit (on-site treatment), Aboveground Petroleum Storage Act (APSA), and Cal-ARP programs, plus all Unified Program permitting and billing activities. These changes only impact regulated facilities in the City of Morgan Hill. Santa Clara County Fire District will continue to be a UPA within the cities of Campbell, Cupertino, and Los Gatos.

How does this change benefit businesses? DEH will implement all Unified Program elements in the City of Morgan Hill, so in most cases only one inspector will visit each business to verify compliance with those State regulations. In addition, questions regarding any of the above programs or your Unified Program consolidated permit can now be directed to a single agency.

Will additional permits be required? No. The format of some parts of Unified Program consolidated permit will be different, but the permitted activities will be the same as those covered by the permits previously issued by DEH for Santa Clara County Fire District.

Will there be any changes to the plan check process? Yes, but for UST systems only. Plans for hazardous materials plan check review will continue to be submitted to the City of Morgan Hill. However, an additional submittal to DEH will now be required for the installation or modification of UST systems regulated by State law. Plan check guidance documents and forms are available on-line at

How does this impact notifications and document submittals? As of January 1, 2013, all unauthorized release (leak) reports, HMBPs, annual HMBP inventory certifications, UST equipment testing notifications, and required submittals associated with UST systems must be made to DEH's Hazardous Materials Compliance Division (HMCD). DEH requests that businesses not submit data electronically via the California Environmental Reporting System (CERS) until further notice. Submittals may be mailed to Santa Clara County HMCD at the address on the letterhead. PDF documents may be sent via email to

If my business generates hazardous waste or treats hazardous waste on-site but is not required to submit a HMBP, how do these changes affect me? The only impacts will be the billing and permitting changes noted above.
