Regulatory Update BY ED THOMAS, NRWA Potential Contaminants for Regulation – The EPA has released their fi nal list of potential contaminants that may need additional research or will be regulated in the future. This is the third list (Contaminant Candidate List 3) that EPA has released as required by the 1996 Safe Drinking Water Act. The Agency must evaluate hundreds of thousands of potential contaminants to narrow down the field of contaminants to approximately 7,500 (CCL Universe). The Agency then uses a scientifically validated process to list approximately 100 contaminants. (See figure 1). The fi nal list was modified based on the Agency’s review of data and resulted in the following determinations: • Removed two pesticides (ethion and nitrofen); • Added 10 pharmaceuticals; one antibiotic (erythromycin) and nine hormones (17 alpha-estradiol, 17-beta estradiol, equilenin, equilin, estriol, estrone, ethinyl estradiol, mestranol and norethindrone); • Added two disinfection by-products (bromochloromethane (Halon1011) and chlorate); • Added perfluorooctane sulfonate (PFOS); • Removed two microbes (Vibrio cholerae and Entamoeba histolytica); • Added three microbes (Mycobacterium avium, Enterovirus and Adenovirus). Of particular interest was the addition of 10 pharmaceutical contaminants. Pharmaceutical and personal care products have begun to get national attention. Regulation of these types of contaminants may be likely in the near future. Potential New Vulnerability Assess– ment Requirements – The U.S. EPA and U.S. DHS have indicated that there is a gap in protecting the nation’s chemical security in the water sector. The U.S. House of Representatives has passed legislation that requires risk-based vulnerability assessments for the water and wastewater sector. The U.S. Senate has indicated that their version of the legislation is imminent. In response, NRWA has been working over the past three years to ensure that the initial SEMS vulnerability assessment software tool would be updated to be compliant with the U.S. Department of Homeland Security’s Risk Assessment Methodology for Critical Asset Protection (RAMCAP). Thanks to funding from DHS, the new software, SEMS-RAMCAP, is free to all utilities and can be downloaded at and full software support will be provided until October 6, 2010 (with the option for funding by the federal government for full software support through June 6, 2014). Completion of the new “RAMCAP Compliant” SEMS is not mandatory under any federal regulation. However, we and DHS are encouraging all utilities to update their vulnerability assessments (VAs) and emergency response plans (ERPs) using the SEMS-RAMCAP software to enhance their protection. The water security legislation recently passed by the U.S. House of Representatives will require all utilities serving more than 3,300 persons to complete new VA’s using a “risk-based” methodology. The new SEMS software was developed in collaboration with the EPA/DHS RAMCAP Working Group. EPA said “both ARAM-W and SEMS are being developed in a manner consistent with the RAMCAP methodology… DHS and the Environmental Protection Agency, the Water Sector Specific Agency, are confident that if approved, the (ANSI/AWWA) Standard will have little impact on the development of the risk assessment methodology tools for the Water Sector….the development of these tools (including SEMS-RAMCAP) …. is consistent and compliant with the RAMCAP methodology.” If you are planning to update your VA and emergency response plan, we would encourage you to use a tool that is RAMCAP compliant. Perchlorate – We have previously reported that the U.S. EPA had used “sound science” and a comprehensive risk evaluation to make an initial determination that perchlorate should not be regulated. Recently, the Agency issued a request for comment in an effort to ensure consideration of all the potential options for evaluating whether there is 34 • First Quarter 2010
