EPA proposes three different tiers of public notification, as summarized in the following table. Note that primacy agencies can designate additional triggers for public notice. The timing and form of the public notice is also spelled out in the proposal. Appendix B contains specific language to be used in public notices for each type of contaminant. Each state that has primary enforcement authority under Part 142 would be required to obtain EPA approval of their programs to implement the revised Subpart Q public notification requirements.
States can choose to add to or change minimum notification requirements.
They may also modify the form and content of public notifications used within their states. Comments on the proposal are due by July 12, 1999. They must reference Docket No. State agencies are also affected by the proposal if they are a primacy agency under the SDWA . Under the proposal, the type of public notice and its timing are prioritized based on the potential hazard of a water quality violation or other circumstance requiring public notification.
