TO:          Regional Water Supply Branch Chiefs
             Regional Counsels

       Last month, pursuant to our policy of reviewing the first three proposed and final
administrative orders (AO) issued by each Region, Region in submitted a proposed AO to
headquarters for our review and comments. This AO was different from any we had previously
reviewed and raised several policy questions. Working together, we have reached an agreement
on these issues and we believe that the issues and their resolution should be shared with all the
Regions. While this AO was issued in the PWS program, the resolutions apply to the UIC
program as well.

       The proposed AO was to be issued to a large public water system for violations of the
turbidity MCL. The proposed AO required the system to:

       (1)    Within 30 days of the effective  date of the AO, submit the name of a consultant or
             an engineer who had been hired to conduct a feasibility study of the water system
             to determine alternatives for achieving full compliance with the requirements of
             the Safe Drinking Water Act;

       (2)    Within 60 days of the effective  date of the order, submit copies of any existing
             reports or studies  that may have been prepared since May 1980, to determine the
             safety and reliability of the existing water supply;

       (3)    Within 120 days of the effective date of the order, submit the results of the
             feasibility study. At a minimum the study was asked to propose one of four
             alternatives for achieving compliance, for example, design,

                                                                                WSG31

construction, and operation of a permanent water filtration plant or design, construction, and
operation of a permanent interconnection with another water system. The feasibility study was
required to contain a schedule for obtaining compliance with the turbidity MCL and the schedule
was to include both interim milestones and a date for final compliance.

       (4)     Within 60 days of acceptance by EPA or the State agency of the results of the
              feasibility study, enter into an enforceable consent agreement which was to
              specify
              a schedule for obtaining compliance with the Safe Drinking Water Act.

       (5)     Report to EPA monthly on its compliance status and its progress towards each of
              the requirements of the AO and to identify any event which caused or might cause
              a delay or other noncompliance with the requirements of the AO.

       The major policy issues raised by this proposed AO are discussed below:

       •      Specifying a Time for Compliance

       Existing AO issuance guidance states that a "reasonable time for compliance" may be
stated in the findings section of the proposed AO. The "reasonable time" stated or specified is the
time required for final compliance with the MCL or other regulation. It is perfectly acceptable for
EPA to issue a proposed AO specifying a "best guess" date for achieving final compliance. EPA
can refine that "best guess" date in the final order using information obtained from the system or
other parties as part of the public hearing and comment process. In any event, including a
deadline date for final compliance will greatly strengthen the enforceability of the administrative
order.

       •      Interim Milestones

       A date for compliance set in the future  due to the need for construction or other
substantial improvements to the system, raises the issue of what assurances EPA has that a
system will take necessary interim steps to come into compliance by the required final date. This
is where interim milestones may be used effectively to help obtain compliance. Setting
milestones may help you to monitor the progress of the system in returning to compliance and to
target further Federal action where progress is insufficient.

-------
                                                                                WSG31

       Whether or not interim milestones would be appropriate or useful depends on the
particular circumstances of the case; for example, how long it will take the system to come into
compliance. Such a determination is best left to the discretion of the Regional office. If you
decide that interim milestones would be appropriate, you should design them from the standpoint
that the more closely they are related to end necessary for achieving final compliance, the more
likely they are to be enforceable. Basically, the milestones should be the steps along the critical
path to final compliance.

       You should set out milestones and associated milestone dates in the proposed AO. Even
if you are not certain of what the exact milestones or dates should be, they should appear in the
proposed AO so that the system, the State, or the public (if there is a public hearing) may
comment upon them. This process allows you to modify the proposed milestones based on the
information you receive as a result of issuing the proposed AO. The outcome of this process
should be a set of milestones which are reasonable and thus defensible.

       •     Enforceability of Interim Milestones

       OECM wishes to counsel that the enforceability of any interim compliance milestones
may be challenged given that the statutory language only expressly authorizes EPA to require
compliance with the statute or regulations. However, OECM recognizes the legitimate interest in
using schedules with interim milestones to help obtain compliance. Therefore, as we stated
above, the milestones should be as closely related and necessary to achieving final compliance as
possible. This will increase the likelihood that the milestones themselves may be enforceable
independent of any violations of the AO requirement for final compliance (particularly where
EPA can show that missing an interim milestone will clearly result in a system owner/operator
missing the final compliance deadline).

       •     Requirement to Enter into an Enforceable Consent Agreement

       We do not believe that this is an appropriate requirement in an Administrative Order. The
compliance schedule which the Region was trying to obtain by this mechanism will be set out in
the proposed AO for comment by the system, the State, and the public, as discussed above.

       •     Monthly Reporting Requirement

       We have advised the Region that this is an appropriate mechanism for tracking the
actions the system is taking to return to compliance.

       We hope that this guidance is helpful to you. If you have any questions, please contact
Patricia Mott, OECM at FTS 475-8320 or Betsy Devlin, ODW at  FTS 382-2303.
