HHW Privacy Policy


Data Collection

The Central Contra Costa Sanitary District operates the Household Hazardous Waste (HHW) Collection Program and owns the HHW Collection Facility located at 4797 Imhoff Place, Martinez, CA 94553. Use of the facility is restricted to residents and small businesses within the HHW service area. To verify their address and eligibility, customers of the facility must present a valid photo identification, such as a driver’s license, at the time of waste delivery.

When a driver’s license is presented by a customer to verify eligibility, HHW staff will scan the license to capture the identification information it contains (name and address only) and save it into a computer database.

Our customers have the right to refuse to allow their driver’s license to be scanned by our staff. In order to use the HHW Collection Facility, customers may instead request that their eligibility information be manually collected by our staff and that only area of origin of the materials be retained in our data base.

Data Use

In addition to verifying the eligibility of customers who wish to use the HHW Collection Facility, the information we collect is used to improve the quality of our services. The data allows us to analyze trends, track program usage, and gather broad geographic information for aggregate use. For example, we can identify communities whose use of the HHW Collection Facility is low in order to provide them with additional outreach regarding the benefits of using the Facility.

Data Security

We recognize our responsibility to treat with care the information we collect about individuals who use the HHW Collection Facility. When customers allow the HHW staff to scan their driver’s license, only the name and address are recorded for HHW program use. The computer servers on which the collected information is stored are kept in a secure environment.

The District is the sole user of the personal information collected by the HHW Program. We will not disclose this information to others in ways different from what is explained in this policy. We never give specific information about individuals to outside parties. Disclosure of any individual’s personal information would require a court subpoena.
