Except when authorized by law, an employee or former employee must not disclose confidential information relating to or maintained by WSSC that is not available to the public. An employee or former employee must not use confidential information for personal gain or the gain of another. Unless expressly prohibited by law, an employee may disclose validly obtained confidential information to a Commissioner or employee if the other Commissioner or employee reasonably needs the information to carry out that person’s official duties. Confidential information includes information that is subject to mandatory or discretionary denial to requests from the public for disclosure under the Maryland Public Information Act or other information determined by WSSC by contractual agreement, standard operating procedure, or otherwise, to be confidential or proprietary in nature.
