Complying With the Revised Drinking
Water Standard for Arsenic: Small
Entity Compliance Guide
One of the Simple Tools for Effective
Performance (STEP) Guide Series
-------
NOTICE: This guide was prepared pursuant to section 212 of the Small Business Regulatory Enforcement
Fairness Act of 1996 (SBREFA), Pub. L 104-121. It is intended to aid you in complying with the Arsenic
and Clarifications to Compliance and New Source Contaminants Monitoring Rule ("Arsenic Rule") issued on
January 22, 2001, under the Safe Drinking Water Act (SDWA). The SDWA provisions, the Arsenic Rule,
and other EPA regulations described in this guide contain legally binding requirements. This document
does not substitute for those provisions or regulations, nor is it a regulation itself. It does not impose
legally-binding requirements on EPA, States, or the regulated community, and may not apply to a particular
situation based on the circumstances. EPA and State decision-makers retain the discretion to adopt
approaches on a case-by-case basis that differ from this guidance where appropriate. Any decisions
regarding a particular community water system or non-transient non-community water system will be made
based on the applicable statutes and regulations. Therefore, interested parties are free to raise questions
and objections about the appropriateness of the application of this guide to a particular situation, and EPA
will consider whether or not the recommendations or interpretations in this guide are appropriate in that
situation based on the law and regulations. EPA may change this guidance in the future. To determine
whether EPA has revised this guide and/or to obtain copies, contact the Safe Drinking Water Hotline at
1-800-426-4791.
Please note that the term "State" is used in this guide to refer to your Primacy Agency. The
Primacy Agency for most systems is your State Drinking Water Agency. However, as of August
2002, the Primacy Agency for systems located in the Navajo Nation is your tribal office, and the
Primacy Agency for systems located on other Tribal lands, in Wyoming, or in the District of
Columbia is your EPA Regional Office.

Certain raw water characteristics can affect a system's waste dis
options and should be considered when selecting an arsenic trea
technology. Raw water characteristics that may affect disposal
alternatives include:
• Excessively high or low pH.
• High concentrations of competing ions (including fluoride
sodium, sulfate, and chloride).
