INTRODUCTION
The Lead and Copper Rule Flow Charts in this document are intended to present the logic
associated with State compliance determination and reporting of required information to EPA for
all aspects of rule implementation. The flow charts have undergone significant modification from
the original set presented in 1992, including corrections to errors in logic and rule citing, as well
as identification of changes in rule logic associated with modifications to the rule that EPA is
proposing in 1996.. The corrections have been presented in ITALIC format, while changes and/or
additions that EPA is proposing have been presented as hand-written and cross-outs, where
appropriate.
Although care has been taken to ensure that these charts accurately reflect the rule and the
proposed changes, if there is any ambiguity in the charts, or differences between the rule and the
charts, the language in the rule should be used for clarification.
