Abstract: The U.S. Environmental Protection Agency (EPA) is proposing to regulate perchlorate in drinking water distributed by public water systems (PWSs). The paperwork burden associated with this proposed rule consists of the burden imposed on systems to read and understand the perchlorate rule as well as the burden associated with certain new collections of information. Specifically, PWSs will have to assign personnel and devote resources to implement the rule, including collecting or compiling initial water samples and submitting this monitoring data to the State. In addition, PWSs will need to attend training sessions and receive technical assistance from their State during implementation of the perchlorate rule. Likewise, the paperwork burden for States include reading and understanding the perchlorate rule. States will have to adopt the NPDWR and develop programs to implement the rule. This may result in States modifying or updating their data systems while implementing the perchlorate rule. States will also have to provide staff with training and technical assistance as well as provide water systems with training and technical assistance for implementation of the perchlorate rule. The information collected under this ICR is critical to States and other authorized entities that have been granted primacy (i.e., primary enforcement authority) for the perchlorate rule. These authorized entities are responsible for overseeing the perchlorate rule implementation by certain PWSs within their jurisdiction. States would utilize these data to determine compliance. The collected information is also necessary for PWSs. PWSs would use these data to demonstrate compliance, communicate water quality information to consumers served by the water system and, if needed, assess treatment options, and operate and maintain installed treatment equipment. States would also be required to report a subset of these data to the EPA. The EPA would utilize the information to protect public health by ensuring compliance with the perchlorate rule, measuring progress toward meeting the perchlorate rule’s goals, and evaluating the appropriateness of State implementation activities.
