This standard describes critical requirements for establishing and operating a protective security program for a water, wastewater, or reuse utility. Topics covered include commitment to security, security culture, defined security roles and employee expectations, vulnerability assessment, resources dedicated to security and security implementation, access control and intrusion detection, contamination detection, monitoring and surveillance, and information protection and continuity. Additionally, the standard covers design and construction, threat level-based protocols, emergency response and recovery plans and business continuity plans, internal and external communications, partnerships, documentation, human resources, and equipment. Determined effective by DHS G430 has been awarded SAFETY Act designation by the U.S. Department of Homeland Security (DHS). The Support Anti-terrorism by Fostering Effective Technologies Act of 2002 (SAFETY Act) was enacted by Congress in the wake of the terrorist attacks on Sept. 11, 2001 as an incentive for the creation and deployment of technologies and services with anti-terrorism capabilities. Under the SAFETY Act, both the entity that creates the anti-terrorism security measure and the entity that deploys the anti-terrorism measure are eligible for liability protections. Under the new designation, utilities in the drinking water and wastewater sector have the assurance of knowing that Standard G430 has been vetted by DHS and determined to be effective. DHS has concluded that the proper utilization of this standard will assist in effectively mitigating acts of terrorism from occurring at water facilities.
