Information Sharing

MarkWest does not sell the personally identifiable information you provide nor does MarkWest share such information with third parties for the purpose of sending you advertisements for products or services unaffiliated with MarkWest or with its affiliates or business partners. MarkWest may, however, share personally identifiable information that you provide to us for legitimate business purposes, including without limitation the following:

  • Transferring such information to MarkWest's affiliates and subsidiaries, unless such transfer is prohibited by law; transferring such information as part of a merger, consolidation, acquisition, divestiture or other corporate restructuring (including bankruptcy);
  • Making such information available to third parties who are providing the product, service or information that you have requested (but never your password);
  • Making such information available to third parties who are providing services to MarkWest or its subsidiaries or affiliates (e.g., providing such information to third parties performing computer-related services for MarkWest or its affiliates (but never your password));
  • Disclosing information when we have a good-faith belief that disclosure of such information is necessary to investigate, prevent, or take action regarding any illegal activities or regarding interference with the operation of our site or violation of its terms of use; and/or
  • Disclosing such information that is allowed by law or that our legal counsel forms a good-faith belief that such disclosure is required by federal or state law, subpoena or court order.

By providing personally identifiable information, you expressly consent to these privacy practices.

Also, MarkWest reserves the right to share any aggregated information (i.e., non-personally identifiable information) with any third parties for any reason, unless prohibited by law.


Given the nature of the internet and the fact that no security system is perfect, MarkWest does not promise that the information you provide will never be obtained by unauthorized persons. MarkWest does, however, utilize industry-standard practices to protect your personally identifiable information from loss, misuse, alteration and destruction. Such measures include using firewalls and Secure Sockets Layers (SSL) to protect certain sensitive transmissions of information. Protection of your information is important to MarkWest and we will work to protect such information to the best of our ability. However, if we should receive any subpoena or enforceable order to disclose information, we will need to comply. In some areas of our Web site, we require a user ID and password for you to access certain information. MarkWest will not disclose such password to third parties; however, you are responsible for maintaining the privacy and security of your password.

Links To Non-MarkWest Sites

For the convenience of our users, some pages of our Web site offer you the ability to link to and view pages of web sites not operated or controlled by MarkWest (such as weather and financial information). Often, but not always, you can tell that you have linked to a non-MarkWest web site because the web site will open a separate browser window. Links by MarkWest to such external web sites do not imply endorsement by MarkWest of that company, its site or its privacy policy. MarkWest and its affiliates do not monitor or control the content or the privacy policies of the external sites and are therefore not responsible for the privacy practices or the content of linked external web sites. When using a link to a non-MarkWest web site, we recommend that you investigate the privacy practices and policies of such external site.

Changes To Our Privacy Policy

MarkWest reserves the right to change this privacy policy at any time. If we decide to change our policy regarding privacy, we will post the revised Privacy Policy on our Web site. You may want to visit this Web site periodically to review the current Privacy Policy. Use of our Web site after the posting of a revised privacy policy constitutes your agreement with the revised policy. This Privacy Policy is not intended to and does not create any contractual or legal rights in or on behalf of any party.
