Tetra Tech, Inc., and its subsidiaries (“Tetra Tech”, “we”, “us”, or “our”) are committed to protecting the privacy and security of your personal information.

The Tetra Tech Privacy Statement–Global, is a global policy supporting country/state-specific laws. This privacy statement outlines the additional disclosures required by the California Consumer Privacy Act (CCPA) and should be read alongside the Tetra Tech Privacy Statement-Global.

This statement will inform you about how we collect, use, and disclose your personal information both online, when you visit this website regardless of where you visit it from, and offline, in line with the CCPA.

Where there are differences in the way we process your personal information due to local laws, we will notify you of this through supplementary or specific website privacy statements.

Tetra Tech will process your personal information in accordance with its privacy statements, unless otherwise required by applicable law.

Personal information we may collect about you

Personal information means any information about an individual from which that person can be identified. It does not include information where the identity has been removed (anonymized information).

The below table lists the categories of personal information and sensitive personal information that may be collected or processed based on your specific transactions and interactions with Tetra Tech, including the personal information collected and processed in the preceding 12 months. For each category of information, the categories of third parties and service providers (data processors) to whom we have disclosed the information in the last 12 months are referenced by a letter that coincides with the letter in the list of categories of service providers and third parties under the section “Disclosure of your personal information” that follows below. No category of personal information listed has been sold or shared in the preceding 12 months.

We do NOT and will not sell your personal information in exchange for monetary or other valuable consideration. We do not share your personal information for cross-context behavioral advertising.

Tetra Tech expects its data processors of your personal information to only use that information for the purpose(s) for which it was originally collected or subsequently authorized by you, as well as respect the security of your data and to treat it in accordance with the applicable law(s). All our data processors and other entities in our group are required to take appropriate security measures to protect your personal information in line with our policies. We do not allow our data processors to use your personal information for their own purposes.

International transfer of your personal information

Tetra Tech is a global organization. Therefore, we may transfer your personal information to other Tetra Tech entities and third parties across the globe and will ensure that your personal information receives an adequate level of protection that is consistent with, and which respects, applicable data privacy laws.

How we protect your personal information

We have put in place appropriate security measures to prevent your personal information from being accidentally lost, used or accessed in an unauthorized way, altered, or disclosed. In addition, we limit access to your personal information to those employees, agents, contractors, and other third parties who have a business need to know. They will only process your personal information on our instructions, and they are subject to a duty of confidentiality.

Third parties will only process your personal information on our instructions and where they have agreed to treat the information confidentially and to keep it secure in compliance with applicable law.

We have put in place procedures to deal with any suspected data security breach and will notify you and any applicable regulator of a suspected breach where we are legally required to do so.

How long we will retain your personal information

We will retain each category of personal information in accordance with applicable law. As this is a global privacy statement, it is impossible to determine how long we will retain each category of data as to all consumers who visit our website or interact with us offline or in other ways from anywhere in the world. In deciding how long to retain each category of personal information that we collect, we consider many criteria, including, but not limited to: the business purposes for which the personal information was collected; relevant national, federal, state, and local recordkeeping laws requiring retention of certain records for minimum periods; applicable statutes of limitations for legal claims to which the information may be relevant; and legal preservation of evidence obligations.

We will only retain your personal information for as long as necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, contractual, or reporting requirements. To determine the appropriate retention period for personal information, we consider the amount, nature, and sensitivity of the personal information, the potential risk of harm from unauthorized use or disclosure of your personal information, the purposes for which we process your personal information and whether we can achieve those purposes through other means, and the applicable legal requirements.

In some circumstances, we may anonymize your personal information so that it can no longer be associated with you, in which case we may use such information without further notice to you.

Your rights in connection with your personal information

Under certain circumstances, and expressly subject to applicable law, you may have the right to:

  • Request access to your personal information (commonly known as a “data subject access request”). This enables you to receive a copy of the personal information we hold about you and to check that we are lawfully processing it. Under the CCPA, you have the right to request, up to 2 times in a 12-month period, that we disclose to you, free of charge, the specific pieces of personal information we have collected about you going back to January 1, 2022, unless doing so would be impossible or involve disproportionate effort, or unless you request a specific time period.
  • Request correction of the personal information that we hold about you. This enables you to have any incomplete or inaccurate information we hold about you corrected.
  • Request erasure of your personal information. This enables you to ask us to delete or remove personal information where there is no good reason for us to continue to process it. Under the CCPA, you have the right to request, up to 2 times in a 12-month period, that we delete personal information that we collected from you, subject to certain exceptions.
  • Right to know where you have the right to request, up to 2 times in a 12-month period, that we identify to you (1) the categories of personal information we have collected about you going back to January 1, 2022, unless doing so would be impossible or involve disproportionate effort, or unless you request a specific time period, (2) the categories of sources from which the personal information was collected, (3) the business or commercial purpose for collecting, selling, or sharing this information, and (4) the categories of third parties with whom we share or have shared your personal information.
  • Right to designate an authorized agent to submit one of the above requests on your behalf. See below for how you can designate an authorized agent.
  • Right to not be discriminated or retaliated against for exercising any of the above rights, including an applicant’s and independent contractor’s right not to be retaliated against for exercising the above rights.

Unless otherwise indicated, if you want to exercise one of the above requests, please contact [email protected]. You may also submit your request via our website at Contact Us.

Verification and Response

We will respond to your request within the timeframe(s) required by applicable law. Please note, we may also need to request specific information from you to help us confirm your identity and ensure your right to access the information (or to exercise any of your other rights). This is another appropriate security measure to ensure that personal information is not disclosed to any person who has no right to receive it.

If you are a California resident, when you submit a Right to Know, Right to Access, Right to Delete, or Right to Correct request through one of the methods provided above, we will ask you to provide some information in order to verify your identity and respond to your request. Specifically, we will ask you to verify information that can be used to link your identity to particular records in our possession, which depends on the nature of your relationship and interaction with us. For example, we may need you to provide your name, email, phone number, IP address, browser ID, amount of your last purchase with the business, and/or date of your last transaction with the business.

Responding to Your Right to Know, Right to Access, Right to Delete, and Right to Correct Requests

Upon receiving a verifiable request from a California resident, we will confirm receipt of the request no later than 10 business days after receiving it. We endeavor to respond to a verifiable request within forty-five (45) calendar days of its receipt. If we require more time (up to an additional 45 calendar days, or 90 calendar days total from the date we receive your request), we will inform you of the reason and extension period in writing. We will deliver our written response by mail or electronically, at your option. The response we provide will also explain the reasons we cannot comply with a request, if applicable.

We do not charge a fee to process or respond to your verifiable request unless it is excessive, repetitive, or manifestly unfounded. If we determine that the request warrants a fee, we will tell you why we made that decision and provide you with a cost estimate before completing your request.

For a request to correct inaccurate personal information, we will accept, review, and consider any documentation that you provide, and we may require that you provide documentation to rebut our own documentation that the personal information is accurate. You should make a good-faith effort to provide us with all necessarily information at the time that you make the request to correct. We may deny a request to correct if we have a good-faith, reasonable, and documented belief that a request to correct is fraudulent or abusive. If we deny your request to correct, we shall inform you of our decision not to comply and provide an explanation as to why we believe the request is fraudulent.

Authorized Agent

If you are a California resident, you can authorize someone else as an authorized agent who can submit a request on your behalf. To do so, you must either (a) execute a valid, verifiable, and notarized power of attorney or (b) provide other written, signed authorization that we can then verify. When we receive a request submitted on your behalf by an authorized agent who does not have a power of attorney, that person will be asked to provide written proof that they have your permission to act on your behalf, and we will also contact you and ask you for information to verify your own identity directly with us and not through your authorized agent. We may deny a request from an authorized agent if the agent does not provide your signed permission demonstrating that they have been authorized by you to act on your behalf.

Other California Privacy Rights

The California Civil Code permits California Residents with whom we have an established business relationship to request that we provide you with a list of certain categories of personal information that we have disclosed to third parties for their direct marketing purposes during the preceding calendar year. To make such a request, please send an email [email protected] or write to us at the address listed below. Please mention that you are making a “California Shine the Light” inquiry.

Automated decision making

We do not envisage that any decisions will be taken about you using automated means. However, we will notify you in writing if this position changes.

Third-party website links

This website may include links to third-party websites, plug-ins, and applications. Clicking on those links or enabling those connections may allow third parties to collect or share data about you. We do not control these third-party websites and are not responsible for them. When you leave our website, we encourage you to read the privacy policy of every website you visit.

Changes to this privacy statement

We reserve the right to update this privacy notice at any time. We encourage you to check our website frequently to see the current Privacy Statement in effect and any changes that may have been made to them.
