Introduction

The purpose of this guidance manual is to provide aid to EPA, States, and public water systems (PWSs)
for the implementation of the Lead and Copper Rule Minor Revisions (LCRMR). The LCRMR were
published in the Federal Register on January 12, 2000.

This manual was developed through a workgroup process  involving Regions, States, and Stakeholders, and
contains the following sections:

Section I summarizes the LCRMR and presents a timetable for implementation of these revisions.
Section II addresses changes to violation and SNC determination and associated SDWIS reporting
requirements, including violation tables to assist States in their compliance activities. Section III covers
State Primacy Revision Requirements, including a detailed  timetable for the application review and
approval process and a Primacy Revision Application crosswalk. This section also contains guidance and
references to help States adopt each new special primacy requirement included in these rules. Section IV
contains: 1) a summary of the LCRMR Technical Guidances; 2) a Question and Answer document
containing EPA's responses to implementation and reporting  questions that arose during data verifications
conducted in State program offices, the development of rule language, fact sheets, flow charts,  and
assorted guidance materials, and training for the LCRMR;  and 3) five Fact Sheets to help States and
large, medium, small, and Tribal systems comply with the new requirements.

The Appendices of this document also provide information that will be useful to States and EPA Regions
throughout the primacy revision application process.  Appendix A contains a comparison of the rule
language of the LCR against the LCRMR using the redline (or red text) and strikeout features of Word
Perfect 8.0  or MS Word 97. Appendix B contains the LCR Reporting Guidance. Appendix C contains
Safe Drinking Water Information System (SDWIS) contaminant codes and flowcharts describing SDWIS
reporting.  Appendix D contains a sample Implementation Agreement which will allow States and EPA to
document how they will share rule implementation responsibilities if the State does not submit a primacy
application by the deadline.  Appendix E contains the sample Memorandum of Understanding between
EPA and the States which will allow States and EPA to document how they will share rule
implementation responsibilities if the State does not submit a primacy application by the deadline.
Appendix F contains a "Statement of Principles" which outlines the criteria EPA will use to determine
whether States with audit laws have retained adequate enforcement and information gathering authority to
meet the requirements of the Safe Drinking Water Act (SDWA).  Appendix G contains training
presentation materials of the LCR and its minor revisions.

I-A.    Rule Executive Summary

I-A.l.   Purpose

The purpose of this summary is to acquaint State decision-makers and public health officials with the
Lead and Copper Rule Minor Revisions (LCRMR).  The LCRMR were published in the Federal
Register on January 12, 2000 (FR Vol. 65 No. 8; wj\w.gBjy^Wsafew<^^            The purpose of
the minor revisions is to streamline requirements, promote consistent national implementation, and, in
many cases, reduce monitoring and reporting requirements.  The LCRMR do not change the action levels
of 0.015 milligrams per liter (mg/L) for lead and 1.3 mg/L for copper, or the Maximum Contaminant Level
Goals (MCLGs) established by the 1991 Lead and Copper Rule (LCR), which are 0 mg/L for lead and
1.3 mg/L for copper. They also do not affect the Rule's basic requirements to optimize corrosion control
and, if appropriate, treat source water, deliver public education, and replace lead service lines (LSLs).
The LCRMR continue to exclude transient non-community water systems from the requirements of the
Rule.

The provisions can be divided into two major categories. The first include those provisions that are more
stringent than the 1991 Rule and must be implemented on April 11, 2000.  The second category include
those provisions that States have the option to adopt as they are not more stringent than the provisions in
the 1991 LCR. The rule summary, which is presented in Section  C of this Section I, discusses only those
provisions that have been added, modified, or deleted by the LCRMR. The summary is organized by
major rule section (i.e., §141.81, §141.82,  §§141.84-141.90, and §141.43).  Where appropriate, the major
rule sections are further divided into the two provision categories.  The LCRMR do not impact any of the
requirements in §141.80 (General requirements), §141.83 (Source water treatment requirements), and
§141.91 (Record keeping requirements for systems).  Therefore, these sections  are not included in this
summary. A comparison of the rule language of the LCR against the LCRMR using the redline (or red
text) and strikeout features of Word Perfect 8.0 or MS Word 97 is provided  as Appendix A.

I-A.2.   Background

EPA promulgated maximum contaminant level goals (MCLGs) and National  Primary Drinking Water
Regulations (NPDWRs) for lead and copper in 1991 (56 FR 26460, June 7,  1991).  The goal of the LCR
is to provide maximum human health protection by reducing lead  and copper levels  at consumers' taps to
as close to the MCLGs as is feasible.  To accomplish this goal, the LCR establishes requirements for
CWSs  and NTNCWSs. These systems must conduct periodic monitoring and optimize corrosion control.
In addition, these systems must perform public education when the level of lead at the tap exceeds the
lead action  level, treat source water if it is found to contribute significantly to high levels of lead or copper
at the tap, and replace lead service lines in the distribution system if the level of lead at the tap continues
to exceed the lead action level after optimal corrosion control and/or source  water treatment has been
installed.

The minor revisions were intended to improve implementation of the LCR.  Most of these changes were
recommended by a work group EPA formed in 1993 composed of Headquarters and Regional EPA staff,
and several State drinking water officials, to identify implementation issues.  Two revisions resulted from
legal challenges to the 1991 LCR brought by the American Water Works Association (AWWA) and the
Natural Resources Defense Council (NRDC). As a result of the AWWA challenge, EPA redefined

State Implementation Guide for the LCRMR               1-1                                     October 2001

-------
"control" of lead service lines to mean that portion of the lines owned by the water system. The NRDC
challenged the LCR's exclusion of transient non-community water systems.  In response to this challenge,
EPA reviewed existing studies and decided to retain this exclusion.

I.A.3.   Development of the LCRMR

In April 1996, EPA proposed a number of minor revisions to the LCR (60 FR 16348, April 12, 1996). The
proposed revisions do not affect the lead and copper MCLGs, action levels, or basic regulatory
requirements.  EPA proposed some of the minor revisions to streamline and reduce regulatory burden
where such changes can be made without jeopardizing the level of public health protection or protection
of the environment.  The Agency proposed other minor changes to clarify requirements and to improve
the rule's implementation. Finally, the Agency addressed two issues that were the subject of a judicial
remand.  The April 1996 Proposal also requested comment on several provisions for which no specific
regulatory changes were proposed.

In an April 1998 Notice, the Agency published, and made available for public review and comment, new
data relating to two of the provisions discussed in the April 1996 proposal and several additional regulatory
options that the Agency was considering (63  FR 20038, April 22, 1998). Finally, in August 1998, EPA
requested additional public comment on a refinement of one of the options discussed in the April 1996
Notice (63 FR 44214, August 18, 1998).

I.A.4.  Benefits of the LCRMR

The LCRMR are not expected to change the level of public health protection resulting from
implementation of the lead and copper regulations. The Agency therefore has not identified any
quantifiable benefits associated with the LCRMR. EPA believes  there should be some non-quantifiable
benefits, however, because improved implementation should result in some health benefits being achieved
sooner.

I.A.5.   Applicability and Compliance Dates

The LCRMR apply to public water systems (PWSs) that are classified as either community water
systems (CWSs) or non-transient non-community water systems (NTNCWSs).

There are some provisions of the LCRMR that are  either more or less stringent than the original LCR or
that clarify the existing provisions of the 1991 LCR.  Systems must comply with the more stringent
requirements  by April 11, 2000. Water systems in States where the State program requirements are
more stringent than the revisions in the LCRMR must wait until their State or other primacy agency
formally adopts the less stringent changes into their State regulations before they can implement them.
Some States may have other mechanisms that will allow systems to take advantage of these changes
prior to State  adoption.

I-B. Key Dates of the Rule

I-B.l   Timetable

The effective date for the Lead and Copper Rule Minor Revisions (LCRMR) is April 11, 2000.  The
LCRMR include two categories of provisions.  The first category includes those provisions that are more
stringent than the 1991 Rule and therefore, must be implemented as of April 11, 2000. The second
category includes those provisions that States have the option to adopt as they are not more stringent than
the provisions in the 1991 LCR.  The table in Figure 1 presents the timetable for implementation of the
LCRMR including the schedule for States to prepare and submit a revised primacy package and to
implement the new reporting requirements.

                              Section  141.81
            Applicability of Corrosion Control Treatment Steps to
                Small, Medium-Size and Large Water Systems
                  Provisions with which all systems must comply as
                                  of April 11,2000.
§141.81(b)1

If the system has corrosion control treatment but is not required to conduct water quality parameter
(WQP) monitoring, the system must:

   •  Properly operate and maintain corrosion control treatment at all times; and

   •  Meet any requirements the State deems are needed to ensure this treatment is maintained.


§141.81(b)(2)

If, prior to December 7, 1992, the system completed treatment steps equivalent to those described in
the  1991 LCR, the system must:

   •  Routinely monitor for WQPs after the State designates optimal water quality parameters
      (OWQPs) (unless the system serves 50,000 or fewer people and no longer exceeds an
      action level); and

      Continue lead and copper tap sampling.


§141.81(b)(3)

If the system has demonstrated that the difference between the 90th percentile lead level at the tap and
the highest concentration  of lead in the system's source water is less than 0.005 mg/L for two,
consecutive six-month periods and to continue as a (b)(3) system under the LCRMR the system must:

      Collect a round of lead and copper tap samples between October 1, 1997 and September 30,
      2000 at the reduced number of sites and continue monitoring every three years thereafter;
      These are not new provisions. They clarify provisions in the 1991 LCR.

State Implementation Guide for the LCRMR             1-7                                 October 2001

-------
   •   Notify the State in writing of any change in treatment or addition of a new source within 60 days
       of the change, unless the State requires earlier notification.  The State may require the system to
       conduct additional monitoring or perform other activities to ensure that optimal corrosion control
       is maintained;

   •   Not exceed the copper action level after July 12, 2001; and

   •   Begin corrosion control treatment steps if during any round of monitoring:
       >  the difference between the system's 90th lead and source water levels is more than 5 ppb,
          (and the system serves more than 50,000people); or
       »•  the system is above the lead action level (any size system); or
       *•  above the copper action level on or after July 12, 2001 (any size system).

Note:  Those systems, serving more than 50,000 people, that are triggered into corrosion control
       treatment steps (for one of the three reasons listed above) must follow the corrosion
       control treatment schedule for medium-size systems outlined in §141.81(e), beginning
       with the requirement to complete a corrosion control study.  These systems must complete
       this study within 18 months of the date they were triggered into the corrosion control
       treatment steps.
         Revisions that Cannot Be Implemented Prior to Approval of State's
                                   Primacy Revision
§141.81(b)(3)

Jf the system's source water lead levels are below the Method Detection Limit (MDL) and its 90th
percentile lead level is 0.005 mg/L or less, the State may deem the system to be optimized under
§141.81(b)(3). (The system would then be affected by the other provisions contained in
§141.81(b)(3).

§141.82(g)

The LCRMR modify the procedure for assessing compliance with WQP monitoring after the State has
designated OWQPs.

   •   Compliance determinations are always based on a six-month period, regardless of the system's
      monitoring schedule (e.g., daily, biweekly, semi-annually, annually, triennially) or whether the
      sample is from an entry point or the distribution system.

   •   Daily values are calculated for each WQP at each sampling location, and are based on the
      sampling frequency for that WQP and sampling point. Daily values are recorded even if no
      sampling has occurred. In this situation, the daily value would be the last daily value calculated.

   •   An excursion is any "daily value" for a WQP that is below the minimum value or outside the range
      of OWQPs set by the State.

   •   The system cannot have excursions for more than a total of nine days at a specific sampling point
      or combination of sampling points, or for a specific WQP or combination of WQPs during a six-
      month period.

   •   Daily values for a sampling location are calculated as follows:

          >    On days when more than one measurement for a WQP at a specific sampling site is
              collected, the daily value is the average of all results collected during the day, unless the
              State tells the system to use a method other than averaging.
          >    A daily value is calculated in the same manner, regardless of whether the measurements
              are collected using continuous monitoring, grab sampling, or both.
          »•    On days when only one measurement is collected, the daily value is the result of that
              measurement.

§141.84(b)

The system now must document in its files the portions of lead service lines (LSLs) it owns and the
relevant legal authorities.
§141.84(d)

Under the LCRMR:

       The system must replace the portion of the LSL that it owns.

       The system must notify the owner (or owner's authorized agent) about the replacement, and
       offer to replace the owner's portion of the line.

   •   The system is not required to pay for replacing the privately-owned portion of the line.

   •   The system is not required to replace the privately-owned portion of the line if precluded by
       law, or where the owner chooses not to pay the cost of replacing the privately-owned portion.

   •   If the system does not replace the privately-owned portion of the line, it must:

          *•   Notify all residents served by the line to be replaced, at least 45 days prior to partial
             replacement.  The State can allow the system to provide less advanced notice if the line
             is being replaced in conjunction with emergency repairs.

          >   Inform the residents) served by the line that the system will, at its expense, collect a
             sample representative of the water in the service line and have it analyzed for lead
             within 72 hours of the partial LSL replacement.

          »•   Report the results of the analysis to the owner and residents within three business days
             of receiving these results.

                                 Primacy Revision
Note: EPA restructured §141.85(a) to allow separate written language for community water systems
(CWSs) and non-transient non-community water systems (NTNCWSs). This required EPA to
extensively renumber the paragraphs within §141.85(a). Refer to Section IV: Other Sources - "The
Lead and Copper Rule Minor Revisions Compared to the 1991 Rule", for a comparison of the
numbering scheme used in the 1991 Rule and the LCRMR. Those numbers that are shaded (if you are
using the Word Perfect 8.0 version) or            in     (if you are using the MS Word 97
version) indicate the new numbering under the LCRMR. Those numbers with a line through them (or
strikeout) are the citations from the 1991 Rule.
§141.85(a)(l)

If the system is a Community Water System:

   •  It may make the following modifications to its mandatory public education language:

          >  The system can delete information regarding LSLs, if it does not have any in its service
             area, and the system receives State approval.

          >  The system can change the language regarding the availability of building permit records
             and consumer access to these records, if the system receives State approval.

          *•  The system can delete the references to "control" of a LSL.

   •  The system can use up its old public education material, even after the LCRMR have taken
      effect.

   •  Newly printed public education materials must discuss the system's responsibilities to its
      customers if it replaces only part of a LSL. This language is included in our revised mandatory
      language.


§141.85(a)(2)

If the system is a NTNCWS, it may:

-------
       Use the mandatory language specified for CWSs or the new language that is geared toward
       NTNCWSs.

       Delete information pertaining to LSLs, if approved by the State.

       Substitute electronic transmission of public education information instead of or combined with
       printed materials, as long as this achieves at least the same coverage.
S141.85fcV21
       EPA has also clarified in the rule that a CWS is only required to deliver public education
       materials within 60 days of exceeding the lead action level, if:

           *•   This is the first time the system has exceeded the lead action level, or

           *•   The system exceeds it again after having monitoring periods in which the system was at
               or below the lead action level.

       The system now has the flexibility to do a separate mailing of public education materials if it is
       difficult to send these materials with the regular bills. The system must include the "alert"
       language in the bill and deliver the mailing within 60 days of exceeding the action level.
§141.85(c)(4)

EPA has clarified in the rule that a NTNCWS is only required to deliver public education materials
within 60 days of exceeding the lead action level, if:

   •   This is the first time the system exceeds the action level, or

   •   The system is exceeding it again after having monitoring periods in which it was at or below the
       lead action level.
§141.85(c)(7)

If the system is a special-case CWS, such as a prison or a hospital, the system can:

   •   Request, in writing, permission from the State to use the new alternate language for
       NTNCWSs, and

   •   Request, in writing, permission from the State to use the alternate delivery methods allowed for
       NTNCWSs.

If the system is a CWS and serves 500 or fewer persons, the system:

   •   Does not have to deliver public service announcements.

   •   Does not have to notify the public via newspapers, and

       Can limit that distribution of pamphlets to facilities that most regularly serve pregnant women
       and children, but the system must also:

           *•   mail or hand deliver the public education materials to all of the system's customers who
               do not already receive water bills; and

           *•   repeat these tasks at least once during each calendar year in which the system exceeds
               the lead action level.

If the system is a CWS and serves 501 to 3,300 persons, the system:

   •  Does not have to deliver public service announcements.

   •  If it has received State permission, the system also:

88141.86(aH5) & (7)

If the system is a CWS without enough Tier 1, 2, or 3 sampling sites, or a NTNCWS without enough Tier
1 or 2 sites, it must complete its sampling pool with representative sites.
S141.86(b₯2)

LCRMR clarify that first-draw samples taken at nonresidential buildings must be 1 liter in volume.


SS141.86fci&
States now have the authority to specify which sampling locations the system must use if it is on reduced
lead and copper tap monitoring.

The system's reduced sampling sites must be representative of the standard monitoring sites.

If the system is required to resume standard monitoring for lead and copper at the tap, it may again:

   •  Resume annual monitoring if it completes two six-month rounds of monitoring that meet the
      criteria of §141.86(d)(4)(ii) and receives written approval from the State.

   •  Resume triennial monitoring if it completes subsequent rounds of monitoring that meet the criteria
      of either §§141.86(d)(4)(iii) or (d)(4)(v) and receives written approval from the State.

If the system is on reduced lead and copper tap monitoring, and it adds a new source or change treatment,
it must notify the State in writing within 60 days of this addition or change.

The State may require the system to:

   •  Notify the State of this change earlier than 60 days, and/or

   •  Require the system to take additional measures, such as commencing standard monitoring,
      increasing WQP monitoring, or re-evaluating corrosion control treatment.

Deleted from SS141.86(a₯8)

The system no longer has to justify to the State in writing why it could not locate enough Tier 1 sites.
The system must still draw 50 percent of its samples from sites with LSLs, lead pipes, or copper pipes with
lead solder, but no longer has to explain to the State in writing why it cannot find enough of these sampling
sites.
S141.86(b₯2)

The system's non-first-draw samples must be one liter in volume and must be collected from an interior tap
that is typically used to provide drinking water.

The LCRMR now make the minimum holding time for acidified lead and copper samples consistent with the
analytical methods for other metals. This replaces the original requirement to have the sample stand in the
original container for at least 28 hours after acidification.
S141.86(b₯5)

If the system is a NTNCWS (or a special-case CWS), it now can apply to the State to use non-first-draw
samples if it does not have enough taps to supply first-draw samples. The system must collect as many
first-draw samples as possible and collect the remaining samples from sites with the longest standing times
possible.  The State can waive this up-front approval either through regulation or written notification to the
system.
8141.86(d₯4)

The system is no longer required to request reduced monitoring status from the State. Rather, the State
must notify the system in writing when it determines the system is eligible to begin reduced lead and copper
tap monitoring. This change applies to both annual and triennial reduced monitoring.

  State Implementation Guide for the LCRMR             1-15                                     October 2001

S141.86fdM41

If the system is on reduced lead and copper tap monitoring, the State can allow the system to collect its
samples in months other than June through September, if the following conditions are met:

      •  The alternate period can be no longer than 4 consecutive months, and

      •  It must represent a time of normal system operation when the highest levels of lead are most
         likely to occur.

The LCRMR specify a transition period for switching to a new monitoring period, in those instances where
the State designates such an alternate monitoring period.

      •  Systems on annual monitoring must collect their next round of samples no later than 21 months
         after the previous round of sampling.

      •  Systems on triennial monitoring must collect their next round of samples no later than 45 months
         after the previous round of sampling.

      •  Small systems with waivers must collect their next round of samples before the end of the 9-year
         period.

EPA has added an accelerated monitoring provision that allows the system to reduce sampling to once
every three years after only 2 consecutive six-month periods of monitoring if it has the following 90th
percentile lead and copper levels at the tap:

      •  lead level of less than or equal to 0.005 mg/L; and

      •  copper level of less than or equal to 0.65 mg/L.

If the system is a small or medium-sized system on a reduced lead and copper monitoring schedule, the
LCRMR clarify that it must resume standard monitoring for lead and copper at the tap and WQPs if it fails
to meet its OWQPs using the new procedure established under the LCRMR (refer back to §141.82(g)).
si4i.86mm

The system may request the State to invalidate a lead or copper tap sample if it can document that at least
one of the following conditions has occurred:

      •   The lab documents that the sample was analyzed improperly;
      •   The State determines that the sample was taken from an improper site;
      •   The sample container was damaged in transit; and/or
      •   The sample was subject to tampering.

Invalidated samples do not count for compliance.
  State Implementation Guide for the LCRMR              1-16                                       October 2001

-------
To request sample invalidation, the system must report the results of all the samples to the State, and
provide supporting documentation for all the samples it believes should be invalidated.
The State must present its decision on whether or not to invalidate the sample(s) in writing. The State may
not invalidate a sample simply because the results of a follow-up sample are higher or lower than that of the
original sample.
S141.86ffK41

If the State invalidates a sample and the system therefore does not have enough valid samples to meet
minimum sampling requirements, the system must collect replacement sample(s):

    •  No later than 20 days after the date the sample was invalidated, or by the end of the monitoring
      period, whichever occurs later.

    •  From the same locations as the invalidated samples, or if the system cannot do this, at locations that
      have not already been used for sampling during that monitoring period.

The system cannot use these replacement samples to meet the monitoring requirements of a subsequent
monitoring period.
S141.86(g)

If the system serves 3,300 or fewer people, the State can grant a monitoring waiver if the system meets
certain criteria. If a system qualifies for a waiver, it must collect lead and/or copper samples at the tap only
once every nine years.
To qualify for a full waiver for both lead and copper, the system must certify to the State that it meets
specific materials criteria for both in its distribution system and drinking water plumbing.

To qualify for a partial waiver for either lead or copper, the system only needs to meet the materials criteria
for that particular contaminant for which it is requesting a waiver.
S141.86(g₯2)

The system must meet specific monitoring criteria to receive a full waiver:

   •   Its 90th percentile lead level must be less than or equal to 0.005 mg/L.

   •   Its 90th percentile copper level must be less than or equal to 0.65 mg/L.

  State Implementation Guide for the LCRMR              1-17                                        October 2001

-------
  •   To receive a full waiver, the system must satisfy the criteria for both lead and copper.  For a partial
     waiver, the system only need meet the criteria for the contaminant for which it is requesting a
     waiver.
The system cannot start monitoring according to the waiver until receiving approval from the State in
writing.

The State can require the system to perform additional activities, as a condition of the waiver.
If a system receives a full waiver, it must:

    •   Monitor for lead and copper at the tap at least once every nine years, at the reduced number of
       sampling sites.

    •   Submit a materials re-certification to the State along with the sample results.

If a system receives a partial waiver, it must:

    •   Monitor and submit re-certification for the waived contaminant as stated above.

    •   Monitor for the non-waived contaminant according to §§141.86(d)(l) through (d)(4), as
       appropriate.

If a system has received a waiver, and later  adds a new source of water or changes treatment,  it must
notify the State in writing within 60 days of the change. In this case, the State may add to or modify the
waiver conditions, if it deems necessary.

If a system becomes aware that it is no longer free of lead- or copper-containing materials, it must notify
the State in writing within 60 days.
A system's waiver will automatically be renewed, unless the system no longer satisfies the monitoring
criteria, materials criteria, and/or the State notifies the system in writing that its waiver has been revoked.

If these occur, the waiver will be revoked. If this happens, the system can re-apply for a waiver, when it
again meets the appropriate materials and monitoring criteria.
If a system's waiver has been revoked and:

    •   The system exceeds the lead and/or copper action level, it must implement corrosion control
       treatment, and any other applicable requirements.

If the system is a ground water system and has installed corrosion control treatment, it now may limit
entry point sampling for WQPs to entry points that are representative of water quality conditions
throughout the system, with prior approval from the State of the system's sampling plan.

8141.87((n

If the State has specified OWQPs, the system must determine compliance with OWQPs:

   •  Every six months, with the first six-month period beginning on the date, the State specified the
      OWQPs.

   •  Using the new procedure that is specified under §141.82(g).

EPA has also specified when the system must collect its WQPs if it was on reduced lead and copper tap
monitoring and then exceeds the action level.

S141.87(e₯2)

EPA has added an accelerated reduced monitoring provision for WQPs. The system now can reduce the
frequency of WQP monitoring at the tap to once every three years more rapidly than before. In order to
qualify, the system must:

   •  Demonstrate for two consecutive monitoring periods that the 90th percentile lead level is no more
      than 0.005 mg/L and the 90th percentile copper level is no more than 0.65 mg/L, and

   •  Be in compliance with OWQP requirements.

   •  The system has source water lead levels of 0.005 mg/L or less and source water copper levels of
      0.065 mg/L or less.

   •  The system maintains these source water levels for three consecutive, three-year compliance

                                  of on April 11,2000.
§141.90(a)(3)

If a system collects lead and copper tap samples less frequently than every six months, it must notify the
State within 60 days of any change to its treatment or addition of a new source.
§141.90(e)(4)

If a system replaces only a portion of a LSL ("partial replacement"):

   •  The system must report the results of the post-replacement lead sample to the State within the
      first 10 days of the month following the month in which the system received these analytical
      results, or as specified by the State.

   •  The State can eliminate the above requirement or require the system to report additional
      information to verify that it has completed all partial LSL replacement activities.


§141.90(0(1)

If a system is required to deliver public education:

   •  The system must submit written documentation to the State, that demonstrates compliance with
      its public education requirements, within  10 days of the end of each period in which the system is
      required to perform public education tasks.

   •  The system is not required to submit its public education distribution list as part of its public
      education compliance letter, if it has already submitted this information previously to the State
      and certifies that this list has not changed [Federal cite §141.90(f)(2)].

Deleted from rule language

The LCRMR eliminate many of the reporting requirements.  The system is no longer required to:

   •  Certify that its samples are first-draw [deleted from §141.90(a)(l)(ii)].

   •  Certify that samples were collected properly by residents [deleted from §141.90(a)(l)(iii)].

   •  Justify in writing to the State why the system has used other than Tier 1 sites [deleted from
      §§141.90(a)(2)&(3)].

   •  Explain to the State in writing why 50% of its sampling sites are not served by LSLs [deleted from
      §141.90(a)(4)].

   •  Submit a written request to the State to go on reduced monitoring [deleted from §141.90(a)(5)].
      System must still receive written approval from the State before it can go on reduced
      monitoring.

   •  Demonstrate that it has limited control of a LSL [deleted from §141.90(e)(4)].
The LCRMR require the system to submit the following information, if the system is:

   •  Requesting sample invalidation, it must send documentation to the State for each sample it wishes
      to have invalidated.

   •  A NTNCWS or special-case CWS without enough taps for first-draw samples, either:

         *• provide to the State in writing an identification of the standing times and locations for the
           non-first-draw samples, or
         * if the State has waived prior approval of non-first-draw sample sites, identify, in writing, each
           site that did not meet the minimum standing time and its actual length of standing time.  The
           system must send this information to the State along with the sample results for lead and
           copper.

-------
The LCRMR also clarify that the system is to report WQP monitoring results within the first 10 days
following the end of the six-month monitoring period specified in §141.87(d).
If the system is a small system requesting a monitoring waiver, it must submit:

    •   The required documentation to the State.

    •   The proper re-certification to the State for each subsequent monitoring period it wishes to keep its
       waiver.

 If the system has a waiver and discovers that it has lead-containing or copper-containing materials in its
 distribution system, it must notify the State within 60 days of the discovery.

 If the system had a waiver prior to the January  12, 2000, it must provide, by October 10, 2001, the
 required monitoring information to the State in order to retain that waiver, if it has not already done so.

 If the system is a ground water system and wishes to limit WQP monitoring to a subset of representative
 entry points, it must send to the State identification and documentation on the selected entry points.


S141.90(h)

If the State has notified a system that it will calculate the system's 90th percentile values, the system does
not need to report these values, but.

    •   The system must send the State the sample results and site selection information by the State-
       specified deadline, along with an explanation for any sample sites that have changed.

    •   The State must provide the results of the calculations, in writing, to the system before the end of
       the monitoring period.

EPA has deleted the one-time requirement for the system to identify and notify persons that may be
affected by lead contamination of their drinking water. This requirement was to be completed by June
1988 and is less comprehensive than the public education requirements. EPA therefore has deleted
these requirements.
§141.43(d)

EPA also revised the definition of "lead free" to reflect the provisions of Sections 1417(d) and (e) of the
1996 Safe Drinking Water Act Amendments.

                                 Records Kept by States

EPA has revised State record keeping requirements to make them consistent with other LCRMR
changes.

§§142.14(d)(8Wll)

States with primary enforcement responsibility must keep records of:
   •  System-specific conditions that States impose on water systems, deemed to have optimized
      corrosion control under §141.81(b)(l) or (b)(3), to ensure that they continue to operate and
      maintain their corrosion control treatment;
   •  Determinations of additional monitoring requirements and/or other actions required to maintain
      optimal corrosion control by systems monitoring for lead and copper at the tap less frequently than
      once every six months that change treatment or add a new source of water;
   •  System-specific decisions  regarding the content of written public education materials and/or the
      distribution of these materials;
   •  System-specific determinations regarding use of non-first draw samples at NTNCWSs and
      special-case CWSs that operate 24 hours a day;
   •  System-specific designations of sampling locations for systems subject to reduced monitoring;
   •  System-specific determinations pertaining to alternative sample collection periods for systems
      subject to reduced monitoring;
   •  Determinations of small system monitoring waivers, waiver recertifications, and waiver revocations;
   •  Determinations regarding representative entry point locations at ground water systems;
   •  System-specific determinations regarding the submission of information to  demonstrate compliance
      with partial lead service line replacement requirements;
   •  System-specific decisions  regarding the resubmission of detailed documentation demonstrating
      completion of public education requirements;
   •  Reports and any other information submitted by PWSs under § 141.90 and records of any 90th
      percentile values calculated by the State  under §141.90(h);
   •  State activities, and the results thereof, to verify compliance with State determinations  issued under
      §§141.82(f),  141.82(h), 141.83(b)(2), and 141.83(b)(4);

States must report quarterly and in a format and on a schedule prescribed by the EPA Administrator.


§142.15(c)(4)(i)

For any reports provided prior to May 15, 2000, States must report the milestones from §142.15(c)(4)
of the original LCR for each applicable PWS, along with the system's name and PWS identification (ID)
number.

For any reports provided after May 14, 2000, and before January 12, 2002, States may report
according to the requirement of the original LCR or begin reporting as required under the LCRMR.


§142.15(cX4)(ui)

For all reports submitted on or after January 12, 2002, States must report in accordance with the new
requirements under the LCRMR.  Specifically, States must report the following:

   •  The name and PWS ID number and 90th percentile lead levels for each monitoring period for all
      large and medium-size systems, and the first and last day of the monitoring period for which the
      90th percentile lead level was calculated.

   •  The name and PWS ID number and 90th percentile lead levels for each monitoring period for all
      small systems that exceeded the lead action level, and the first and last day of the monitoring period
      in which the exceedance occurred.

   •  The name and PWS ID number and 90th percentile copper levels for each monitoring period for all
      PWSs that exceeded the copper action level, and the first and last day of the monitoring period in
      which the exceedance occurred.

   •  All name and PWS ID numbers for each PWS for which States have designated optimal WQPs,
      or which States have deemed to have optimized corrosion control under §141.81(b)(l) or (b)(3),
      the date of the determination, and the paragraph(s) under which States made their determination.

States have the option to designate a different method than that outlined in §141.82(g)(l) for aggregating
multiple measurements collected during the same day for a water quality parameter (WQP) at a sampling
location.  Section 141.82(g)(l) specifies that the daily value of a WQP is the average of all results
collected during the day at a given site. If they elect to use a different formula, States must explain this
alternate formula in their application for primacy.
Deleted from §142.16(d₯31

The LCRMR eliminate the requirement to designate how States will verify PWS demonstrations of limited
control over lead service lines, since EPA has eliminated all reference to "control" of lead service lines in
the Minor Revisions.
§142.16(d₯3)

States must explain how they will verify that systems have completed all partial lead service line
replacement activities.  Under the LCRMR, systems must replace the portion of the lead service line that
they own, and must offer the owner to replace the privately-owned portion of the line. Systems replacing
only a portion of a line must notify residents served by the line in advance of the replacement.  Such
systems must also notify residents that the system will collect a sample representative of the water in the
service line within 72 hours after completion of partial line replacement, and provide results of the lead
concentration of the sample to residents within three business days.
§142.16(d₯4)

Under the LCRMR, States can allow systems on reduced monitoring to collect samples during a period
other than June through September.  Such a period must be no longer than four consecutive months and
must represent a time of normal operation when the levels of lead are most likely to be highest. If States
plan to designate an alternative period for sample collection for CWSs subject to reduced lead and
copper tap monitoring, they must describe in their application for primacy how they plan to designate

II-A.  Summary of Revised State Reporting Requirements

II-A.l.  Purpose

The purpose of this summary is to provide State agencies with an understanding of how the State reporting
requirements have changed since EPA issued guidance in May 1992, entitled, Lead and Copper Rule
Definitions and Federal Reporting for Milestones, Violations, and SNCs.  The reason for this change is
twofold.  First, on January 12, 2000, EPA published minor revisions to the 1991  Rule.  The Lead and Copper
Rule Minor Revisions (LCRMR) modify some State reporting requirements, and  impact some compliance
determinations due to changes in some requirements for water systems. The LCRMR do not change the
action levels of 0.015 milligrams per liter (mg/L) for lead and 1.3 mg/L for copper, or the Rule's basic
requirements to optimize corrosion control and, if appropriate, treat source water, deliver public education,
and replace lead service lines.

Second, through the EPA Data Sharing Committee (DSC),  EPA re-evaluated the number of LCR violations
that States should report to EPA and have consolidated some of these violation types. EPA has also revised
some of the compliance period begin and end dates for some of the violation types to promote better tracking
of these violations.

EPA has also developed Revised State Reporting Requirements for the Lead and  Copper Rule, a reporting
guidance to help systems and States understand the reporting requirements for the entire LCR, including the
revisions.  This guidance is contained in Appendix B of this Implementation Guidance.  As noted, this
Reporting  Guidance contains information needed for reporting on the entire rule, whereas this  only discusses
the changes to the LCR reporting as impacted by the LCRMR. In addition, flow charts designed to assist
regulators  with reporting and enforcement issues are presented as Appendix C.

II-A.2.   How Have State Reporting Requirements Changed?

To oversee the implementation of the LCR, EPA originally established reporting requirements for 11
milestones and 15 violation types. The revisions to the LCR have impacted the number of milestones that
States must report to EPA and have changed some of the criteria for what constitute a violation; however,
EPA has not added any new violation types.  Instead, EPA has consolidated and expanded the definitions of
some of the violation types.  An overview of the changes to the milestone, sample,  and violation reporting are
provided below.

II-A.2.a.  Changes to Milestone Reporting and 90th Percentile Values

The LCRMR eliminate the requirement for States  to report the completion of several of the  interim milestones;
however, the minor revisions do not eliminate corresponding State recordkeeping requirements.  They also
add two new milestones  and require States to report all 90th percentile lead levels for large and medium-size
systems, and clarify in rule language that States must report the first and last day of the compliance period for
which the  90th percentile levels were calculated.

To further simplify State reporting requirements, all exceedances are reported only as  sample records, not
as milestone records.  (SDWIS/FED will no longer generate milestone records from 90th percentile sample
records that are also exceedances.)

                Yes
     The LCR did not require States to report any 90th percentile levels below the action level (i.e., "non-
     exceedances).  However, in the 1992 LCR reporting guidance, EPA requested that States report the
     90th percentile lead non-exceedances for all large systems, and for medium and small systems once
     they exceeded the lead action level.
II-A.2.b.  Changes to Violation Reporting

EPA established the EPA DSC to compile drinking water program data needs, review current reporting
requirements, and recommend changes to these requirements that would best meet EPA's data objectives.
One of the DSC's goals was to reduce the complexity of the LCR reporting requirements. The DSC evaluated
the number of violations required to be reported for the LCR, and consolidated some of the violation types,
reducing the number of violation types from 15 to 10.

In addition, for some violations, EPA changed how compliance periods are characterized in SDWIS/FED.
For these violations, the compliance period begin date reflects the first day after the end of the time period for
which the requirement was to be evaluated; the compliance period end date is December 31, 2015.  This
change will more accurately portray the length of time a system is in violation, and will facilitate tracking of
significant noncompliers (SNCs).

Table 2 summarizes the consolidation of violation codes and also specifies any changes to compliance period
begin/end dates.

1 The begin date is the day after the requirement was to occur. The end date is defaulted by
SDWIS/FED to December 31, 2015. The return to compliance date or "intentional no-action" date
replaces the defaulted December 31, 2015. This change will better characterize the period of time in
which a system is in violation.
2 The begin date is the first day of the compliance period and the end date is the last day of the

II-A.3.  When Should States Begin Reporting These New Violation Type?

As of January 20, 2000, SDWIS/FED has been able to accept all revised reporting requirements (i.e., the
revised milestone and sample information required under the LCRMR, the consolidated violation codes, and the
revised begin and end dates for violation type codes 51, 57, 58, and 65). Although EPA specified in the
State Implementation Guidance for the LCKMR
II-5
October 2001

-------
LCRMR that States may begin reporting the revised requirements on May 14, 2000, EPA has completed
programming changes in SDWIS/FED, and can accept the revised information ahead of schedule.
Until January 14, 2002, States have the option to continue to report violations, samples, and milestones, as
described in the 1991 LCR, or States may report according to the revised reporting requirements. By January
14, 2002, States must report the revised milestone and sample information in accordance with the LCRMR. In
addition, the data needs to comply with the revised reporting formats to be accepted by SDWIS/FED. A
summary of this schedule is provided in Table 3.
Table 3
Schedule for Reporting Revised Milestones, Lead 90th Percentile Data,
and Consolidated Violations
May 14, 2000 to January 13,
2002
January 14, 2002 and
thereafter
States may continue to report the requirements described in the
1992 reporting guidance
or
States may report in accordance with the new requirements under
the LCRMR:
S all lead 90th percentile levels for large and medium
systems
S lead 90th percentile exceedance for small systems
S copper 90th percentile exceedances for all systems
S streamlined LSLR milestone
S Done and Deemed milestones (Initial - deemed and done
requested by February 15, 2001)
States must report in accordance with all new LCRMR requirements
Note: The LCRMR do not change the frequency of reporting. States are still required to report 90"1
percentile levels, milestones, and violations quarterly.
In January 2000, the existing milestone and violation data in SDWIS/FED were converted as appropriate.
Violation data were converted as appropriate to the consolidated violation type codes and compliance periods.
In addition, SDWIS/FED created 90th percentile sample records for all 90th percentile copper exceedances and
for those 90th percentile lead milestone records, for which a corresponding sample record  did not already exist.
EPA then  archived the obsolete milestone and violation data. These data are available upon request to EPA or in
the frozen databases for the periods prior to fiscal year 2000.

From May 14, 2000 to January 13, 2002, for new data submissions, SDWIS/FED will convert the violation
codes of 54, 55, 60, 61, and 62 into the appropriate consolidated type code. During this time period, 90th
percentile exceedances that are reported using the C800 milestone record instead of the C2100 sample record
will be converted to sample records. Milestone data for the other deleted milestones and lead service line
replacement rates will not be posted to SDWIS/FED but will be rejected.  Beginning January  14, 2002, obsolete
data will be rejected (i.e., violations with obsolete violation type codes, 90th percentile lead and copper
State Implementation Guidance for the LCRMR

  exceedances reported as milestones, milestone data for the other deleted milestones, and annual rates for lead
  service line replacement).

II-B.  Significant Noncompliers (SNCs)

II-B.l.   WhatisaSNC?

A SNC is a system that has more serious, frequent, or persistent violations.  The SNC designation is reserved for
those systems that are considered to pose the most serious threats to public health.

II-B.2.   Have the SNC definitions been revised as a result of the LCRMR?

EPA has not developed any new SNC conditions as a result of the rule revisions.  However, under the LCR
systems with initial tap lead and copper violations were allowed additional time to return to compliance prior to
their being identified as SNC. We are well past the initial tap monitoring periods for all but the very new systems,
therefore, the additional time is no longer appropriate. From April 2001 forward, systems will be evaluated against
the revised SNC criteria in the 4th month following the quarterly compliance period as are all other SNC/violation
conditions. Returned to compliance will be based on the system having completed all appropriate requirements
and having monitored for 2 consecutive 6-month periods for the monitoring and reporting conditions listed above.
In certain circumstances , completion of the specific  requirement may be overtaken by other events, making
completion moot. In those circumstances, the State should report the new follow-up action code of "intentional
no action."

In addition, some changes have been made to SNC determination with respect to: consolidation of the OCCT and
SOWT installation violations into one violation code  (58); changes in system public education reporting
requirements; and changes in characterization of violation compliance periods for initial tap M/R and Installation
violations (i.e., the violation compliance period begin date will be the first day after the end of the time period for
which the requirements were evaluated, and the violation compliance period end date will be December 31, 2015).

When a return to compliance (RTC) is linked to one of these violations, the compliance period end date of
December 31, 2015 will be replaced by the RTC date. Until then,  if a system is still in violation for one of these
violations, it will continue to qualify for SNC status.

II-B.3.   What are the SNC Definitions for the three SNC types?

Table 4 provides the  SNC definitions for the three types of SNCs.

III-A.    State Primacy Program Revision

40 CFR 142 sets out requirements for States to obtain and/or retain primary enforcement responsibility
(primacy) for the Public Water System Supervision (PWSS) program as authorized by Section 1413 of the
Safe Drinking Water Act (SDWA).  The 1996 SDWA Amendments update the process for States to obtain
and/or retain primacy.  On April 28, 1998, EPA promulgated the Primacy Rule to reflect these statutory
changes (63 FR 23361).

ID-A.l    Primacy Revision  Process

Pursuant to § 142.12, Revision of State Programs, States must submit to the EPA Administrator complete and
final requests for approval of program revisions to adopt new or revised EPA regulations no later than 2 years
after promulgation of the new or revised federal regulations (see Figure 1). Until the Lead and Copper Rule
Minor Revisions (LCRMR) primacy application is submitted, or the submitted State LCRMR regulations
become effective, whichever is later, EPA Regions have responsibility for directly implementing the LCRMR.
EPA and the States can enter into agreements under which the States implement the LCRMR between the
time that the rule becomes effective and when the States submit a final primacy revision package to EPA. A
sample LCRMR implementation agreement that States and EPA may use to assist them in their discussions is
provided as Appendix D. This sample agreement has 3 components. Part I lists general implementation
responsibilities.  Part n lists each of the  provisions that were required to be implemented by April 11, 2000.
In addition to a listing of provisions, Part n provides a two-column table to allow States and EPA to identify
which party has responsibility for each provision. Part m lists provisions that can be implemented now under
the federal regulations. States should evaluate whether they can implement these changes under their current
regulations.

As Regions and States develop implementation agreements, they can complete the sample implementation
agreement and use it to document responsibilities.  States and Regions can also use the sample agreement as a
basis for discussions and craft their own implementation agreement format. EPA requested that States and
Regions complete implementation agreements by April 11, 2000. Extension agreements should cover the
period between the rule effective date and the date that the State receives Primacy for the LCRMR.

III-A.l.a. LCRMR Provisions

The LCRMR provisions fall into two general categories:  1) those provisions that systems were required to
begin implementing on April 11, 2000 and that States must adopt to retain primacy; and 2) those that are not
more stringent, but allow flexibility and improvements in implementation.  States are not required to adopt
these changes to maintain primacy. Some States may not be able to implement these changes until they
update their own regulations.

Provisions That Must Be Adopted—Provisions that became effective on April 11, 2000 and that States
must incorporate into their drinking water regulations are marked with a O in the Primacy Revision Crosswalk
(see page in-20). Because the effective date for these provisions is well in advance of the deadline for State
adoption of these revised requirements, EPA will take steps to enter into implementation agreements with
States to ensure that the new requirements are implemented.
 State Implementation Guidance for the LCRMR            III-l                                  October 2001

-------
Provisions Designed to Improve Implementation — These provisions are less stringent than the 1991
LCR.  They were effective on April  11, 2000 at the federal level.  State regulations with more stringent
requirements remain in effect in most States until the States adopt their own regulations in response to the
LCRMR. EPA anticipates that States will work with their water systems to ensure that the water systems
understand which requirements will be enforced in their State.

   revised reporting requirements in §142.15(c) by January 12,2002.

   EPA suggests that States submit complete and final primacy revision applications by October 2001 to ensure timely program
   revision. Primacy revision applications, in complete and final form are due to EPA January 12, 2002. States may request an
   extension of up to 2 additional years.
III-A.l.b.   The Revision Process
 State Implementation Guidance for the LCRMR
III-2
October 2001

-------
The approval of State program revisions is recommended to be a two-step process comprised of submission
of a draft request (optional) and then submission of a complete and final request for program approval.  Figure
2 diagrams these processes and their timing.

Draft Request — At a State's option, it may submit a draft request for EPA review and tentative
determination. This request should contain drafts of all required primacy application materials.  The State
should submit a draft request by January 2001.  EPA will make a tentative determination on whether the
State's program meets the applicable requirements.  The tentative determination should be made within 90
days.

Complete and Final Request— This submission must be in accordance with §§142.12(c)(l) and (2) and
include the Attorney General's statement.  States must also include their response to any comments and/or
program deficiencies identified in the tentative determination (if applicable). EPA Regions should make States
aware that submission of only  a final request may make it more difficult for States to address any necessary
changes within the allowable time for their rule adoption.

EPA requests that States submit their complete and final revision package within 21 months from the date of
publication of the LCRMR (i.e., by October, 2001). This will ensure that States will have interim primacy
within 24 months and will prevent them from becoming backlogged with revision applications to adopt future
federal requirements.

States and EPA Regions should agree to a plan and timetable for submitting State primacy revision application
as soon as possible after rule promulgation—ideally within 5 months.

III-A.2.  The Final Review Process

Once  the State primacy revision application is complete and final, EPA has a regulatory (and statutory)
deadline of 90 days  to review  and approve or disapprove of the revised program.  The Offices of Ground
Water and Drinking Water (OGWDW) and Enforcement and Compliance Assurance (OECA) will conduct
detailed reviews of the first State package from each Region. Upon a satisfactory completion of the review,
OGWDW and OECA will waive concurrence on all other State programs in that Region, although they will
retain the option to review additional State programs with cause. The Office of General Counsel (OGC) has
delegated its review and approval to the Office of Regional Counsel (ORC).

In order to meet the  90-day deadline of the first State package from each Region, the review period will be
equally split giving both the EPA Regions  and Headquarters 45 days to conduct their respective reviews. For
the  first package in each Region, Regions should forward copies of the primacy revision application to the
Implementation and Assistance Division Director in OGWDW, who will take the lead on the review process.
OGWDW will provide OECA with a copy for their concurrent review. OECA will concur on OGWDW
approvals.

II-B.   State Primacy Program Revision Extensions

III-B.l.  The Extension Process

Under §142.12(b), States may request that the 2-year deadline for submitting the complete and final request
for EPA approval of program revisions be extended for up to 2 additional years under certain circumstances.
The extension request must be submitted to the Region within 2 years of the date that EPA published the
regulation (by January 12, 2002), although EPA suggests that States submit this application by January 2001.
The Regional Administrator has been delegated authority to approve extension applications.  Headquarters
concurrence on extensions is not required.

III-B.2.  Criteria that an Extension Request Must Meet

For an extension to be granted, a State must demonstrate that the reasons that it cannot meet the original
deadline are beyond its control, and that the State made a good faith effort to do so. A critical part of the
extension application is the State's proposed schedule for submission of its complete and final request for
approval of a revised primacy program. The application must also demonstrate at least one of the following:

    (i)      That the State currently lacks the legislative or regulatory authority to enforce the new or revised
            requirements; or,

    (ii)  That the State currently lacks the program capability adequate to implement the new or revised
        requirements; or,

    (lii) That the State is requesting the extension to group two or more program revisions in  a single
        legislative or regulatory action.

In addition, during this extension period, the State must agree to implement the EPA requirements to be
adopted in its program revision within the scope of its current authority and capabilities.

III-B.3.   Conditions of the Extension

Jf an extension is granted, the State and EPA Region will negotiate certain  conditions that must be met during
the extension period. These conditions will be determined during the extension approval process and are
decided on a case-by-case basis. The Region and State must establish a memorandum of agreement to cover
this period. EPA recommends that the memorandum of agreement be based on the LCRMR
implementation agreement, modified as to include relevant actions. A sample Memorandum of Understanding
agreement is presented as Appendix E.
 State Implementation Guidance for the LCRMR            III-6                                   October 2001

-------
Conditions of an extension agreement may include:

        •     Informing PWSs that the Region will be overseeing implementation of the requirements until it
             approves the State program revision or until the State submits a complete and final revision
             package or until the  State regulations in the submitted revision package become effective
             (whichever comes later), if the State qualifies for interim primacy;
        •     Collecting, storing and managing laboratory results, public notices, and other compliance and
             operation data required by EPA's regulations;
        •     Assisting the EPA Region in the development of the technical aspects of enforcement actions
             and conducting informal follow-up on violations (telephone calls, letters, etc.);
        •     Providing technical assistance to PWSs;

        •     If the State's request for an extension is based on a current lack of program capability adequate
             to implement the new requirements, taking steps agreed to by the  State and EPA Region during
             the extension period to remedy the deficiency;
        •     Providing the EPA Region with all the information required under § 142.15 on State reporting.

Figure 3 on the next page provides a checklist the EPA Region can use to review State extension requests.

I-C.   State Primacy Package

The Primacy Revision Application package should consist of the following sections:

III-C.l.  The State Primacy Revision Checklist (40 CFR 142.10)

This section is a checklist of general primacy requirements, taken from 40 CFR 142.10, as shown in Figure 4.
In completing this checklist, States must identify the program elements that they have revised in response to
new Federal requirements. If an element has been revised, since the last primacy application approval, States
should indicate a "Yes" answer in the second column next to the list of program elements and should submit
appropriate documentation.  For elements that need not be revised, States need only list the citation and the
date of revision in the second column.  During the application review process, EPA will insert findings and
comments in the third column.

States may still receive interim primacy for the LCRMR even if they have not yet revised their base program
to comply with the new statutory requirements (PWS definition and administrative penalty authority) provided
that the time to adopt these requirements (including the extension period if applicable) has not expired.

States may bundle the LCRMR primacy revision packages with other regulations (e.g., new PWS definition,
administrative penalty authority, variance and exemption requirements). States should be careful to insure the
submittal date (two years plus two year extension) has not lapsed on any of the regulations. If States choose
to bundle the LCRMR requirements with those of other requirements, States must include the text of their
regulation/statute for which they are requesting primacy. The Attorney General statement should reference
each regulation/statute included in the primacy package.
III-C.2.  Text of the State's Regulation

Each primacy application package should include the text of the State regulation.


ID-C.3. Primacy Revision Crosswalk

The Primacy Revision Crosswalk summarizes only those provisions in §§141.80-141.82 and §§141.84-
141.90 that have been amended since the LCR was published on June 7, 1991. It includes the three technical
amendments that were published in the Federal Register (on July 15, 1991; June 29, 1992; and June 30,
1994), and the new requirements under the LCRMR.  Section 141.83,  Source Water Treatment
Requirements and §141.91, Recordkeeping requirements (for systems), were not revised and are not
included in the Crosswalk. Further, the Crosswalk contains §141.43, Prohibition on Use of Lead Pipes,
Solder, and Flux.  This section was also included as part of the LCRMR. The summaries of each revision in
the Crosswalk are intended to assist States in revising their regulations.

In the Crosswalk, those provisions that States must adopt in order to retain or obtain primacy are marked
with a O.  A State must adopt these provisions by January 12, 2002, unless EPA has granted a State an
extension. For any provisions not marked with a O, States can choose to implement them, or decide not to
implement them.  States may  also choose the timeframe in which they implement these requirements.

Some of the revisions to the rule are only clarifications that explain what EPA intended in the 1991 LCR; they
are not actually new requirements.  EPA has marked these revisions in the crosswalk with the word,
* clarification*.  If such a requirement as clarified by EPA is already explicitly written in the State's drinking
water regulations, the State does not need to adopt the provision before  implementing it.
 State Implementation Guidance for the LCRMR            III-11                                  October 2001

-------
States should complete the Crosswalk by specifying the sections of their statute or regulation that contain
enforceable provisions comparable to those contained in the revised federal regulations. EPA will use the
Crosswalk to review the State applications for consistency with federal law.  If the State's provisions differ
from Federal requirements, the State should explain how its requirements are "no less stringent". It is
important that States include the title of the revised statute or regulations, the new or revised section or
paragraph number, and the page number on which the relevant provision can be found. Providing this
information will be helpful to the EPA Regions when reviewing the State's request for approval of its primacy
revisions.

The crosswalk is large and therefore has been included at the end of Section m.

IH-C.4  State Reporting and Recordkeeping Checklist (40 CFR 142.14 and 142.15)

This checklist, presented as Figure 5, addresses State reporting and recordkeeping requirements for the
LCRMR.  This checklist only includes the requirements that have been revised by the LCRMR. States should
use this checklist to explain how their reporting and  recordkeeping requirements are consistent with Federal
requirements. If a State's requirements are different from  the Federal requirements, it must explain how its
requirements are none the less in compliance with federal  requirements.

                 Figure 5: Reporting and Recordkeeping Checklist for the LCRMR
Requirement
Are the State's policies
consistent with Federal
requirements?
If not, please explain.
Recordkeeping
States with primary enforcement responsibility must keep records of:
System-specific conditions that States impose on water systems, deemed to have
optimized corrosion control under §141.81(b)(l) or (b)(3), to ensure that they
continue to operate and maintain their corrosion control treatment, as per
§142.14(d)(8)(i).
Determinations of additional monitoring requirements and/or other actions required
to maintain optimal corrosion control by systems monitoring for lead and copper at
the tap less frequently than once every six months that change treatment or add a
new source of water, as per §142.14(d)(8)(ix).
System-specific decisions regarding the content of written public education
materials and/or the distribution of these materials, as per §142.14(d)(8)(x).
System-specific determinations regarding use of non-first draw samples at
NTNCWSs and special-case CWSs that operate 24 hours a day, as per
§142.14(d)(8)(xi).

requirements. If, for the records identified in paragraphs § 142. 14(d)(8)(i) through
(d)(8)(xvii), no change is made to State determinations during a 12-year retention
period, the State must retain the record until a new decision, determination, or
designation has been issued, as per §142.14(d)(ll).
If the State has primary enforcement responsibility, it no longer needs to keep
records of determinations that a system does not control entire lead service lines, as
was specified in §141.84(e) in the original LCR.
Are the State's policies
consistent with Federal
requirements?
If not, please explain.

 For any reports provided prior to May 15, 2000, States must report the milestones
 from §142.15(c)(4) of the original LCR for each applicable PWS, along with the
 system's name and PWS identification number, as per §142.15(c)(4)(i).
 For any reports provided after May 14, 2000, and before January 12, 2002, States may
 report according to the requirement of the original LCR or begin reporting as
 required under the LCRMR, as per §142.15(c)(4)(ii).
 For all reports submitted on or after January 12, 2002, States must report in
 accordance with the new requirements under the LCRMR, as per §142.15(c)(4)(iii).
 Specifically, States must report the following:
     1 The PWS ID number and 90th percentile lead levels for each monitoring period
      for all large and medium-size systems, and the first and last day of the
      monitoring period for which the 90th percentile lead level was calculated.
    The PWS ID number and 90th percentile lead levels for each monitoring period for
    all small systems that exceeded the lead action level, and the first and last day of
    the monitoring period in which the exceedance occurred.
     1 The PWS ID number and 90th percentile copper levels for each monitoring period
      for all PWSs that exceeded the copper action level, and the first and last day of
      the monitoring period in which the exceedance occurred.
     1 All PWS ID numbers for each PWS for which States have designated optimal
     WQPs, or which States have deemed to have optimized corrosion control under
     §141.81(b)(l) or (b)(3), the date of the determination, and the paragraphs) under
     which States made their determination.
     1 All PWSs required to begin replacing lead service lines, and the date each

     control, completed source water treatment requirements, and completed lead
     service line replacement requirements, and the date of the State's determination
     that these requirements have been met. The date reported must be the latest of:

           The date the State designates optimal WQPs or deem the system to have
           optimized corrosion control under §141.81(b)(l) or (b)(3);
           For systems triggered into source water treatment, the date the State

Guidance for Special Primacy Requirements (40 CFR 142.16)
  State Implementation Guidance for the LCKMR
                                      111-14
                                                                                                        October 2001

-------
This section contains guidance States can use when addressing the special primacy requirements of 40 CFR
142.16 — requirements unique to specific regulations of the LCRMR.  This section addresses:
    •  the three new special primacy conditions added by the LCRMR (the addition of paragraph
        142.16(d)(4) and revision of paragraphs (d)(l) and (d)(3)),
    •  the one condition eliminated by these minor revisions, and
    •  the technical correction to the special primacy requirements.

States must describe in their application how they will implement the following new provisions.  The first
provision regarding partial lead service line replacement is one States must adopt in order to retain primacy,
and States must describe in their  application for primacy revision how they plan to implement this provision.
A State is only required to include descriptions for the second and third provisions if they have adopted the
relevant portion of the LCRMR and plan to implement them in their State.

States should note that, in several sections, the guidance makes suggestions and offers alternatives that go
beyond the minimum requirements indicated by reading the subsections of §142.16. EPA does this to
provide States with information and/or suggestions that may be helpful to States' implementation efforts.  Such
suggestions are prefaced by "may" or "should" and are to be considered advisory. They are not required
elements of States' applications for program revision.
            ALL STATES MUST RESPOND TO THE FOLLOWING SPECIAL PRIMACY REQUIREMENT
§142.16 Special Primacy Requirements (d)(3): Section 141.90 (e) - Verifying compliance with lead
service line replacement schedules and completion of all partial lead service line replacement
activities.

Guidance

Section 141.84(b) requires that systems shall replace annually at least 7 percent of the initial number of lead
service lines in its distribution system. The annual replacement program must begin on the date the lead action
level was exceeded which triggered the lead service line replacement program.  Under the LCRMR, systems
must:

    •  Replace the portion of the lead service line that they own, and

    •  Offer to the owner to replace the privately-owned portion of the line.

Section 141.90(e) requires systems to report any additional information as specified by the State, and in a
time and manner prescribed by the State, to verify that all partial lead service line replacement activities have
taken place. For §142.16(d) States must explain how they will document or verify that systems have
completed all partial lead service line replacement activities.
 State Implementation Guidance for the LCKMR            III-15                                  October 2001

-------
To address this provision, States may impose a requirement for systems to report annually, monthly or on an
alternative schedule no less frequently than annually, their progress in completing all lead service line
replacements and meeting the annual replacement schedules required in §141.84. System reporting used to
verify progress and completion may include any or all of the following:

    •  A signed statement by the system owner verifying all lead service lines (or an annually required
       number of lines) have been replaced in part or in whole. If any lead service lines were only partially
       replaced, the number of partial replacements should be reported.

    •  A signed statement by the owner of the service line or their authorized agent (when other than the
       owner of the water system) acknowledging receipt of the system's offer to replace the privately-
       owned portion of the line, and whether the offer was accepted or declined.

    •  Documentation from contractor records, billing receipts or other means by which the State can verify
       replacement of lead service lines has been completed.

Note:  States that have no systems with lead service lines should include a statement to that effect
       in their primacy package.
        SPECIAL PRIMACY REQUIREMENTS REQUIRED ONLY IF THE STATE HAS
          ADOPTED THE RELEVANT PORTIONS OF THE LCRMR AND PLANS TO
                                     IMPLEMENT THEM
§142.16 Special Primacy Requirements (d)(l) State designation of optimal corrosion control (ii):
Section 141.82(g) - Designating an alternative approach for aggregating multiple measurements
collected during the same day for a water quality parameter at a sampling location, if the State elects
to adopt a formula other than the one specified in Sec. 141.82(g)(l) of this chapter.

States adopting §141.82(g)(l) as is do not need to respond to this special primacy requirement.

Guidance

States have the option to designate a different formula than that outlined in §141.82(g)(l) for aggregating
multiple measurements collected during  the same day for a water quality parameter (WQP) at a sampling
location.  Section 141.82(g)(l) specifies that the daily value of a WQP is the average of all results collected
during the day at a given site, regardless of whether they are collected through continuous monitoring, grab
sampling, or a combination of both.
 State Implementation Guidance for the LCRMR           III-16                                 October 2001

-------
Some States may elect to use an alternative methodology for calculating daily values for optimal water quality
parameter requirements. If so, the State must explain their alternative method and provide justification
sufficient to show it is at least as stringent as the average of the daily values described in §141.82(g)(l).

In considering this option, States may have reason to believe an alternative formula may be more
representative for calculating daily values for WQPs for some systems. Examples of situations which may
trigger an alternative methodology include the following:

•   For systems performing continuous monitoring of a WQP(s), the State may prescribe the monitoring
    frequency at which data would be used for calculating the daily value. For example, values recorded
    every four hours may be used to calculate the daily average.

•   For systems with large fluctuations in the values obtained for a WQP(s) the extreme value most
    detrimental to corrosion of distribution system piping may be required to be reported (e.g., the lowest pH
    value obtained).

•   For sample locations at a common header which is served by multiple sources (and where water quality
    fluctuates based on the particular sources in service at the time of sampling), a formula representing the
    water quality contribution of the source providing the most water may be required.
§142.16 Special Primacy Requirements (d)(4): Section 141.86 (d)(4)(iv)(A) - Designating an
alternative period for sample collection for community water systems subject to reduced monitoring.

Guidance

Section 141.86(d)(4)(iv)(A) adds the provision that States may approve a different period for conducting the
lead and copper tap sampling for systems performing reduced monitoring.  The alternative period would be
other than the current four-month period of June, July, August and September, specified in §141.86
(d)(4)(iv). The June through September time period was defined because it was believed the highest levels of
lead at the tap were most likely to occur during warm weather months. Under the LCRMR, States can allow
systems on reduced monitoring to collect samples during a period other than June through September. Such a
period must be no longer than four consecutive months and must represent a time of normal operation when
the levels of lead are most likely to be highest.

Recently published data and analyses pertaining to the effect of temperature on lead and copper leaching
indicate there are several  factors which might explain why metal levels could frequently be higher in cold
weather months, various  combinations of which may be simultaneously present in a given water system.
These factors include:
 State Implementation Guidance for the LCRMR            III-17                                  October 2001

-------
    •   The intrinsic net solubility of many minerals, especially carbonates, increases as the temperature
        decreases.

    •   Corrosion inhibitors, especially orthophosphate, may react more slowly at lower temperatures, so
        passivating film formation is less effective in colder water.

    •   Corrosion inhibitors and other treatment chemicals may be more viscous at lower temperatures.
        Therefore, the chemical feed rates may be lower when cold.

    •   Many pipes are near heating systems, and in the winter the operation of the heating systems causes
        the pipes to be hotter.  Plus, the change in temperature could also disrupt the existing protective films
        in the pipes built up over the earlier months of more stable temperatures.

    •   Dissolved oxygen levels are often higher in colder waters,  resulting in increased concentrations of
        oxidants (e.g., oxygen, free chlorine, chloramines) in the water.  This causes more rapid increases in
        metal levels through enhanced oxidation during short standing times (less than 16 hours).

The revised language of the LCRMR allow States to retain the requirement to conduct reduced monitoring
during the months of June through September. However, EPA believes that the requirement to limit reduced
monitoring to warm weather months is no longer justified.  If States plan to designate an alternative period for
sample collection for reduced lead and copper tap monitoring, they must describe in their application for
primacy how they plan to designate such a period (i.e., how they will ensure that the lead levels will likely be
at their highest during the alternate period).

A State may detail program criteria using appropriate items cited above, additional information pertinent to
their State or systems, or by describing how criteria will be established on a system-by-system basis.

The person or entity responsible for making the determinations should be identified and should include those
most knowledgeable about the particular water system, its operational practices and water chemistry, and
other system-specific issues that may affect lead corrosion.

           PROVISIONS OF THE LCRMR SPECIAL PRIMACY REQUIREMENTS
                             THAT DO NOT REQUIRE RESPONSE
§142.16 Special Primacy Requirements (d)(l) State designation of optimal corrosion control (i):
Sections 141.82(d), 141.82(f) and 141.82(h) - Designating optimal corrosion control treatment
methods, optimal water quality parameters, and modifications thereto.

Note this is solely a renumbering of the requirements and requires no response.
Deleted from §142.16(d)(3)

The LCRMR eliminate the requirement to designate how States will verify PWS demonstrations of limited
control over lead service lines, since EPA has eliminated all reference to "control" of lead service lines in the
Minor Revisions.

Repromulgation of §142.16(d)

The June 30, 1994 (59 FR 33864) Technical Correction repromulgates the special primacy requirements
under §142.16(d) that were initially promulgated in the 1991 LCR. Section 142.16(d) had been inadvertently
deleted during the promulgation of the Phase II rulemaking (56 FR 3526, January 30, 1991).
III-C.6.   Attorney General's Statement of Enforceability

The complete and final primacy revision application must include an Attorney General statement certifying that
his/her State regulations were duly adopted and are enforceable. The Attorney General statement should also
certify that his/her State does not have any audit privilege or immunity laws, or if it has such laws, that these
laws do not prevent the State from meeting the requirements of the SDWA. Similarly, if the State is not
adopting the new PWS definition because it has no "constructed conveyance systems," the Attorney General
should certify that his/her State statute or regulation is "as stringent as" the federal  requirements and that any
future constructed conveyance systems will be prohibited. If the State has submitted this certification with a
previous revision package, then it should indicate the date of submittal and the Attorney General  need only
certify that the status of the audit laws has not changed since the prior submittal. An example of an Attorney
General statement is presented in Figure 6. A "Statement of Principles", which outlines the criteria EPA will
use to determine whether States with audit laws have retained adequate enforcement and information
gathering authority to meet the requirements of the SDWA, is presented as Appendix F.

    Statement is approved and signed, and will be fully effective by the time the program is
    approved.

    Guidance For States on Audit Privilege and/or Immunity Laws

    In order for EPA to properly evaluate the  State's request for approval, the  State Attorney
    General or independent legal counsel should certify that the State's environmental audit
    immunity and/or privilege and immunity law does not affect its ability to meet enforcement and
    information  gathering requirements under the Safe Drinking Water Act. This certification
    should be reasonably consistent with the wording of the State audit laws and should
    demonstrate how State program approval criteria are satisfied.

    EPA will apply the criteria outlined in its "Statement of Principles" memo issued on 2/14/97
    (See Appendix F) in determining whether States with audit laws have retained adequate
    enforcement authority for any authorized federal programs. The principles articulated in the
    guidance are based on the requirements of federal law, specifically the enforcement and
    compliance  and State program approval provisions of environmental statutes and their
    corresponding regulations. The Principles  provide that if provisions of State law are
    ambiguous,  it will be important to obtain opinions from the State Attorney General or
    independent legal counsel interpreting the law as meeting specific federal requirements.  If the
    law cannot be so interpreted, changes to State laws may be necessary to obtain federal
    program approval.  Before submitting a package for approval, States with audit privilege
    and/or immunity laws should initiate communications with  appropriate EPA Regional Offices to
    identify and discuss the issues raised by the State's audit privilege and/or immunity law.
    Model Language

    I.   For States with No Audit Privilege and/or Immunity Laws

    Furthermore, I certify that [State/Commonwealth of 0}] has not enacted any environmental
    audit privilege and/or immunity laws.

    II. For States with Audit Laws that do Not Apply to the State Agency Administering
        the Safe Drinking Water Act

    Furthermore, I certify that the environmental [audit privilege and/or immunity law] of the [State/
    Commonwealth of 0}] does not affect (3} ability to meet enforcement and information
    gathering requirements under the Safe Drinking Water Act because the [audit privilege and/or
    immunity law] does not apply to the program set forth in the "Program Description." The Safe
    Drinking Water Act program set forth in the "Program Description" is administered by (5); the
    [audit privilege and/or immunity law] does not affect programs implemented by (51 thus the
    program set forth in the "Program Description" is unaffected by the provisions of
    [State/Commonwealth of 0}] [audit privilege and/or immunity law].

    in. For States with Audit Privilege and/or Immunity Laws that Worked with EPA to
        Satisfy Requirements for Federally Authorized, Delegated or Approved
        Environmental Programs

    Furthermore, I certify that the environmental [audit privilege and/or immunity law] of the [State/
    Commonwealth of 0}] does not affect (3} ability to meet enforcement and information
    gathering requirements under the Safe Drinking Water Act because [State/Commonwealth of
    (3}] has enacted statutory revisions and/or issued a clarifying Attorney General's statement to
    satisfy requirements for federally authorized, delegated or approved environmental programs.

§141.82 DESCRIPTION OF CORROSION CONTROL TREATMENT REQUIREMENTS
Continued operation and monitoring
• Compliance will be determined every 6 months as specified under §141 .87(d).
System is out of compliance during any 6-month period in which it has excursions for
any State-specified parameter on more than 9 days during period.
• An excursion occurs when the daily value for any WQP is below minimum value or
outside range designated by the State.
Daily values for a sampling location are calculated as follows:
S On days when more than one measurement for WQP is collected, daily value is
average of all results collected during day.
S Daily value is calculated in same manner, regardless of whether measurements are
collected using continuous monitoring, grab sampling, or both.
S If EPA has approved alternative formula under §142.16, the State's formula is to
be used to aggregate multiple measurements taken at sampling point for WQP in
lieu of formula in this paragraph.
S On days when only one measurement is collected, daily value is the result of that
measurement.
S On days when no WQP measurement is collected, daily value is one calculated on
most recent day on which WQP was measured at sample site.

• Health effects of lead
places where lead is normally found
lead poses significant risk to health
greatest risk is to pregnant women and young children
Lead in drinking water
lead in drinking water can significantly increase a person's total lead exposure,
especially in infants
lead enters drinking water primarily through corrosion of distribution mains and
household plumbing containing lead
in 1986, Congress passed laws regulating lead content in plumbing
tap water that has been standing for several hours can contain high lead levels
• Steps to Reduce Exposure
flush tap before using water for drinking or cooking when water has been unused

§141.90 REPORTING REQUIREMENTS
Except as provided in §141.90(a)(l)(viii), systems must report information specified in
§ 1 4 1 . 90 for all lead and copper tap samples and WQP samples specified in § 1 4 1 . 87 within
first 10 days after end of each monitoring period.
Deletes requirement for systems to certify that all samples are first-draw. This is replaced
by requirement for systems to submit documentation to State for each lead or copper tap
sample for which they request invalidation.
Deletes requirement for systems to certify that residents collected samples after system
had informed them of the proper sampling procedures.
[Note: EPA has added no new requirements to this paragraph.]
Systems do not have to submit 90th percentile concentrations if State calculates 90th
percentile levels for system.
Systems must now report results of all WQP samples collected under §141.87(c)-(f) during
each six-month monitoring period specified in §141.87(d) within first 10 days following
end of monitoring period unless State has specified more frequent reporting requirement.
• Deletes requirement that CWSs justify their selection of tier 2 and/or tier 3 sites.
NTNCWSs and special-case CWSs that do not have enough taps to supply first-draw
samples must either:
S Provide written documentation to State identifying standing times and locations
for enough non-first-draw samples to make up sampling pool under § 141 .86(b)(5)
by the start of the monitoring period, unless State has waived prior approval of
non-first-draw sample sites selected by system; or

IV-B.  Technical Information Available on the LCRMR

A series of guidance manuals will support the LCRMR. The manuals will aid EPA State agencies, and
affected PWSs in implementing the rule revisions and will help ensure that implementation among these
groups is consistent. EPA made these manuals available for public review in Spring 1999, and has
revised them based on the comments received. A brief description of each manual is provided below.

^  How to Determine Compliance with Optimal Water Quality Parameters as Revised by
    the Lead and Copper Rule Minor Revisions (EPA 815-R-99-019)
    This guidance document explains the new procedure for determining compliance with optimal
    water quality parameters (OWQPs), as modified by the LCRMR. It provides seven examples
    that illustrate how to assess OWQP compliance under various monitoring scenarios (e.g., multiple
    WQP samples collected per day, triennial monitoring, monitoring by seasonal systems).  This
    guidance also includes the federal regulatory language from the LCRMR that pertains to water
    quality parameter monitoring, related system reporting requirements, and the revised OWQP
    compliance procedure.

^  Lead and Copper Rule: Summary of Revisions (EPA 815-R-99-020)

    This guidance contains a discussion of each of the important revisions to water system
    requirements that were made to the LCR by the LCRMR, and identifies when systems must begin
    following these new requirements. The appendix to this document contains a comparison of the
    rule language of the LCR against the LCRMR. This comparison is also provided as Appendix A
    to the Implementation Guidance and is available as a Word Perfect  8.0 or MS Word 97 file.

^  Monitoring Waivers under The Lead and Copper Rule Minor Revisions for Systems
    Serving 3,300 or Fewer  People (EPA 815-R-99-021)

    This guidance provides a detailed discussion of monitoring waivers to help small systems
    understand  if they might qualify for a waiver and how to apply for one.  It contains examples of
    waiver application forms that a system can use to  apply for a monitoring waiver and instructions on
    how to complete them. This guidance also contains federal regulatory language from the LCRMR
    that explains the monitoring waiver requirements.

^  Notification  and Reporting Requirements for Partial Lead Service Line Replacement
    under the Lead and Copper Rule (EPA 815-R-99-022)

    This guidance document explains how the LCRMR have changed the information a system must
    provide to its customers who are served by lead service lines, and to the State, in the event that
    the system does not replace the entire length of a lead service line (i.e., partial lead service line
    replacement). This document also provides  systems with suggested language to use when notifying
    their customers who are connected to a partially-replaced lead service line and the federal
    regulatory language that pertains to partial lead service line replacement requirements.

IV-C. Questions and Answers

EPA has developed interpretations for implementing and reporting issues related to the Lead and
Copper Rule (LCR) that were raised during data verification (DVs) audits. In addition, while
developing rule language, fact sheets, flow charts, and assorted guidance materials, and providing
training for the Lead and Copper Rule Minor Revisions (LCRMR), EPA raised and discussed many
issues related to implementation and reporting. The Office of Enforcement and Compliance Assistance,
Office of Water (Regulatory Implementation Branch, Data Management Branch, Standards Division),
the Office of General Counsel, the LCR Workgroup, EPA Regions, and States have had the
opportunity to provide input on the interpretation of these LCR issues.  Based on discussions and
responses, EPA has compiled and summarized the issues relating to the implementation and reporting
for the LCR and Lead and Copper Rule Minor Revisions (LCRMR). Questions and interpretations are
outlined below.

1.      Definitions for Compliance Period, Monitoring Period, Event Due Date,
       Noncompliance Period

A.     How and why is EPA defining the terms: "compliance period", "monitoring period, "event due
       date", and "noncompliance period".

A:     EPA is using these terms to characterize when a requirement must be completed and
       to define noncompliance as follows:

       Compliance Period: The period associated with the overall period of time or frequency
       interval established for a requirement (e.g., 6 months, annual, triennial, or 9-year
       waiver period).

       Monitoring Period: The specific period within the compliance period in which the
       system was designated to perform the requirement (e.g., June-September).

       Event Due Date:  The due date or deadline for an event (e.g., installation completion
       date).

       Noncompliance Period: The first day after the due date of the requirement to the day
       compliance achieved.

2.      Schedule for New State Reporting Requirements

Q:     When must States report according to the new reporting requirements? According to the
       Federal Register, this date is January 14, 2002.

A:     Although the LCRMR regulatory language refers to January  12, 2000 as the date
       States must begin reporting the new requirements, the Federal Register lists January
State Implementation Guidance for the LCKMR          IV-4                                 October 2001

-------
       14, 2002 as the date for required reporting.  This is because January 12, 2002 is a
       Saturday.

3.      Minimum Sampling Requirements

Q:     Some States allow systems to collect fewer samples than required according to the table in 40
       CFR 141.86.  For example, if a system does not have enough sites, a State required the system
       to sample only from the sites the system did have. Second, if a system had multiple taps at a
       site (e.g. a highrise), the State allowed the system to collect only one sample for that particular
       site. Are either of these scenarios allowed?

A:     The LCRMR clarify that all systems are required to collect samples from a minimum
       number of sites in accordance with §141.86(c), even if a sufficient number of high-risk
       sites are not available. If a system has an insufficient number of high-risk sites, it
       must collect samples from representative sites. The system should collect samples
       from multiple taps at the site, if different plumbing materials are used at various taps
       at the site. The system should evaluate a site to determine the number of samples that
       accurately reflect lead and copper exposure to consumers.  For some systems, more
       than one sample will need to be collected from the same site to meet the minimum
       sampling requirements.  If this is necessary, the  samples should be collected on
       different days.
Q:     If a system has collected enough samples to determine if the 90th percentile levels exceed the
       action levels (or not), but has not collected the required minimum number, must the system take
       the rest of the  samples?
A:     Yes, the system must still take the minimum number of samples.
Q:     If a system collects fewer than five samples, how should they calculate their 90th percentiles?

A:     According to the LCR, 90th percentile values cannot be calculated with fewer than five
       samples. The system must collect a least 5 samples to calculate the 90th percentile
       level.

4.      Failing to Finish Initial Tap Sampling
Q:     What are the monitoring requirements for a system that was placed on reduced monitoring before
       it had enough rounds at or below the action level?

A:     Since it did not qualify for  reduced monitoring, it must properly perform initial
       monitoring (i.e., collect two consecutive, 6-month rounds of monitoring) and progress
       from that point onward.
Q:     Systems sometimes fail to complete two rounds of initial sampling. Either they miss a round
       entirely, the two rounds are not collected in consecutive  six-month periods, or they do not collect
       enough samples in one or both rounds. Is a "51" violation (initial lead/copper tap M/R) recorded
State Implementation Guidance for the LCRMR           1V-5                                  October 2001

-------
       for each round that was missed?  If the system does not monitor beyond the two first rounds,
       should the State continue to report a 51 violation?

A:     Under the revised LCRMR SDWIS/FED Reporting requirements, if a system has a
       monitoring violation in the first and/or second round, the State should report a single
       "51" violation. The initial monitoring requirement is to collect 2 sets or rounds of tap
       samples within 2 consecutive 6-month periods. There is no additional initial monitoring
       after the two consecutive 6 month  rounds - or the one for those med/small who exceed
       in the first round. Therefore, the single 51 violation lasts until both rounds are taken.
       See Appendix B (the reporting guidance) for specific details. Additionally, the system
       no longer has the 3-6-12  month additional time to complete the initial monitoring before
       it becomes an SNC. If a system gets a 51 violation,  it becomes a SNC. Additionally, the
       system would only receive a single 51  violations and not two 51 violations.

Q:     If a system was incorrectly placed on reduced monitoring, and failed to sample during the period
       specified by the State, should a follow-up M/R violation be reported?

A:     The system should be required to complete all required monitoring within the
       appropriate regulatory timelines AND the system should receive the appropriate
       monitoring violation for  the specific monitoring requirement it failed to complete.
       Example: If the state incorrectly placed the system on triennial monitoring after only 2
       annual sample sets, the system should receive a routine monitoring violation (type 52).
       If the system failed to conduct the  initial monitoring, two consecutive 6-month rounds
       before it was placed on annual, it should receive a 51 violation and should be required to
       conduct the two consecutive rounds.  In the second  scenario, because  the system did
       not complete initial monitoring, it cannot incur a violation for follow-up/routine
       monitoring.
Q.     Some systems fell behind and did not complete two initial rounds according to the schedule cited
       in the rule. To avoid becoming SNCs, some States considered systems to be in compliance as
       long as the system completed two full rounds of sampling within one year.  Is this acceptable?

A:     When the Rule was first implemented, many  States and their labs were falling behind in
       completing the required two initial rounds of monitoring.  If the two initial rounds of
       monitoring were conducted and completed in  the year time period (one round during
       warm weather),  this was  acceptable.

5.      Reduced Lead and Copper Tap Monitoring

Q:     Is a system on annual monitoring required to monitor every 12 months or some time during the
       specified year? Is a system on triennial monitoring required to monitoring every 36 months, or at
       some time during the specified 36-month period?

A:     The system must monitor during the  months of June through  September (unless the
       State has  designated other consecutive months to conduct monitoring), each year (if on
       annual monitoring) or every third  year (if on triennial monitoring).

Q:     In those situations where a system on reduced lead and copper tap monitoring is transitioning to
       an alternate monitoring period, is the 21  and 45 months counted from the month the most recent

State Implementation Guidance for the LCRMR           1V-6                                   October 2001

-------
       samples were collected, or the respective monitoring period or compliance period for which they
       conducted monitoring?

A:     The 21 and 45 month deadlines are calculated starting the day after the end of the
       previous monitoring period, (i.e., the June to September period, or the actual period
       they had sampled).  The 21-month transition period allows for the alternate monitoring
       period to be reached without requiring the system to monitor twice in the same current
       annual monitoring period, or to extend  the period of monitoring beyond a full annual
       compliance period. The same philosophy applies to the 45-month transition period for
       those on triennial monitoring.  Failure  to meet these deadlines would result in a 52
       violation. Violations of these transition periods should have a violation begin date of the
       first day after the end of the designated alternate monitoring period, not the first day of
       the 22nd or 46th month.

Q:     Can 2 consecutive 6-months rounds of lead and copper tap monitoring in which both 90th
       percentile levels are at or below the action  level count as the first year toward a small or medium-
       size system's qualifying for triennial lead and copper tap monitoring?

A:     Yes, the wording of §141.86(d)(4)(iii), "A small or medium-size system that meets the
       lead and copper action levels during three consecutive years... ", is consistent with
       this interpretation. Therefore, a system that serves 50,000  or fewer people that is at or
       below both  action levels for two, consecutive 6 months, followed by two consecutive
       annual rounds of monitoring would qualify for triennial lead and copper tap monitoring.
Q:     Is a system eligible for accelerated reduced lead and copper tap monitoring after two consecutive
       annual rounds of monitoring?

A:     No. Two consecutive 6-month periods are required for a system to be eligible for
       accelerated reduced lead and copper tap monitoring because a system that meets the
       accelerated reduced monitoring criteria after 2 consecutive  rounds of annual monitoring
       would already qualify for triennial lead  and copper tap monitoring.  However, eligibility
       for accelerated reduced water quality parameter monitoring is based on 2 consecutive
       rounds of any duration.

6.      Reporting 90* Percentile Values

Q:     Can copper non-exceedances be accepted  by  SDWIS?

A:     No. EPA is not accepting these data at  this time.

Q:     According to the 1992 LCR Reporting Guidance, 90th percentile lead levels were to be reported
       for small systems starting with the first lead action level exceedance, and forever, thereafter,
       regardless of whether subsequent exceedances occurred.  Is this still the case?

A:     States are only required by the rule to report 90th percentile lead and copper levels
       which exceed the action level for  small  systems. However, EPA encourages the
       reporting of all 90th percentile lead levels for all water  systems, regardless of size.
State Implementation Guidance for the LCRMR           1V-7                                    October 2001

7.      Rounding and Significant Figures

Q:     What is EPA's policy concerning rounding and significant digits, (e.g., 5 is always rounded
       upward)?

A:     EPA's policy when calculating data for compliance purposes, is to round-off by dropping
       the digits  that are not significant. The last significant digit is increased by one unit if the
       digit dropped is 5 or higher. If the digit is 4 or lower, the preceding number is not
       changed.  This policy is outlined in Water Supply Guidance 21, Joseph A. Cotruvo,
       Ph.D., Director of Criteria and Standards Division, ODW; Memorandum - "Procedures
       for Rounding-Off Analytical Data to Determine Compliance with Maximum Contaminant
       Levels Present in NIPDWR", April 6, 1981.

8.      Sample Invalidation

Q:     Can a sample be invalidated if the sample is taken from a vacant house or one that has been
       unoccupied for a while?

A:     Samples taken  from vacant houses or ones that have been unoccupied for an extended
       period of  time are valid samples, and should not be invalidated unless the criteria for
       invalidation have been met. Systems should provide instructions to residents or
       persons taking the samples to first flush their taps if they have been away for several
       days, let the water sit unused for at least six hours, and then collect the sample.

Q:     A system is on reduced lead and copper tap monitoring and is required to sample from June to
       September. It samples in September and the samples are invalidated on September 30. Should
       the system collect replacement samples, or have they missed this monitoring period, and incur a
       violation?

A:     If replacement samples are taken by October 20, the system is in compliance because
       the replacement samples were collected with 20 days of the State's invalidation
       decision, even though sampling was not conducted within the 4-month monitoring
       period. If samples are taken  on October 21 or later, the system has a violation. The
       late samples may not be used to determine 90th percentile levels. This system must
       wait until June - September of the following year to monitor.  If the system properly
       monitors  and reports, it can RTC at that time. EPA recommends that systems sample
       early in the monitoring period to prevent a monitoring violation from occurring.

Q:     If a State allowed samples to be invalidated prior to January 12, 2000, is this considered
       acceptable?

A:     No.  A State cannot implement new provisions before they are effective.

9.      Monitoring Waivers

Q:     Once a monitoring waiver is granted, should the new compliance period begin on the day after the
       end of the  previous monitoring period, or on the day after the  last sample was taken? For
       example, a system on triennial monitoring (compliance period = Jan. 1999 to Dec. 2001,
State Implementation Guidance for the LCRMR           1V-8                                   October 2001

-------
       monitoring period from June to September) is granted a 9-year monitoring waiver on April 10,
       2000. It collected samples and reported to the State on June 10, 2000.

A:     The new compliance period would begin on the day after the end of the most recent
       monitoring period, (not compliance period).  So, the new compliance period would be
       October 1, 2000 to September 30, 2009.

Q:     If a system that was granted a monitoring  waiver is late in submitting its sampling results, should
       the waiver be revoked?

A:     According to the LCRMR, the system no longer meets the waiver criteria and the
       waiver must be revoked.

10.     Demonstrating that a System Meets the (b)(3) Criteria

Q:     Does a system that meets the criteria of §141.81(b)(3) (also referred to as a (b)(3) system) need
       to continue to prove it meets the (b)(3) criteria?

A:     The State may require the system to continue to collect source water samples to
       confirm its  (b)(3) status.  In this instance, the system would collect source water
       samples during the same monitoring period that it collects triennial lead and copper tap
       samples.

       Under §141.81(b)(3), a system is deemed to have optimized corrosion control  if it meets
       the following criteria :
           •   the difference between the 90th percentile tap water lead level and the highest
               source water lead level is less than or equal to 0.005 mg/L.
           •   for 2, consecutive, 6-month periods the systems that has source water lead
               levels below the MDL and 90th percentile lead levels that are less than or equal
               to 0.005 mg/L.
           In addition, a (b)(3) system that exceeds the copper action level after July 12, 2001
           will no longer qualify as a (b)(3)  system.  Such a system must begin corrosion control
           treatment steps, unless such treatment is already in place.

11.     Water Quality Parameter Monitoring

Q:     How should large systems that monitor daily or more frequently for water quality parameters
       (WQPs) report their results?

A:     The State may  specify how frequently these values must be recorded and reported.  In
       those instances where the State has adopted the new procedure for determining
       compliance with optimal water quality  parameters (OWQPs), the LCRMR clarify that a
       system must report WQP monitoring results within the first 10 days following the end of
       the 6-month monitoring compliance period specified in §141.87(d).

12.     Water Quality Parameter Compliance

Q:     If a system has excursions at the very end of June, how many excursions in July are needed for
       the system to be considered in violation with its OWQP requirements?


State Implementation Guidance for the LCKMR           IV-9                                    October 2001

-------
A:     The daily value count would start over with a new 6-month compliance period. The
       system would not be in violation until it had excursions for more than nine days between
       July and December, even if it had excursions for nine days at the end of June.  The
       system would have to use the excursion from the last monitoring period as the daily
       value for each subsequent day until it sampled again.  Thus, the system could potentially
       have excursions for 18 straight days without being in violation (9 in June, 9 in July).

Q:     Is a small or medium-size system considered to have returned to compliance for a WQP M/R
       violation, if its 90th percentile levels for lead and copper are at or below the action levels?  Or
       would it still be required to collect WQPs? The 1992 LCR reporting guidance indicated that these
       systems would not be required to sample.

A:      It would still be required to conduct the WQP sampling for it to be considered
       "returned to  compliance."  If it fails to conduct the WQP sampling, an "intentional no
       action" record would be reported which indicates  other circumstances made specific
       compliance with the violated requirement moot, in this case 2 consecutive 6-month
       rounds of lead and copper tap results at or below  the action levels.  A medium or small
       system which exceeds the action level is required to collect WQP samples in the period
       in which the  action level exceedance occurred.  At the same time, the system is
       triggered into corrosion control treatment steps.  Medium and small systems are
       required to submit a recommendation for corrosion control to the state within 6 months
       after the exceedance and the WQP data is an integral part of the information necessary
       for the system to make (and the state to approve) it's recommendation. Failure to do so
       should result in  a recommendation violation. To return to compliance for the WQP
       monitoring violation, the system would complete the required round of sampling as soon
       as possible to ensure it's recommendation is timely.

Q:     If a system fails to collect enough entry point samples, it incurs a WQP M/R violation. If it
       monitors properly for the next 6-month compliance period, is it considered to have returned to
       compliance?

A:     Yes.

Q:     How does a system  return to  compliance if it is in violation of  its OWQP requirements (i.e., has a
       WQP noncompliance violation)?  Must it have no more than 9 days with excursions in the
       subsequent  6-month compliance  period?

A:     A WQP Noncompliance Violator whose 90th percentile levels no longer exceed the
       action level, is not  required to monitor, nor would the excursion values carry over into
       the next subsequent period for an exceedance.  This should be reported as Intentional
       No-Action, since it technically did not RTC in this case. (Refer to the table on page IV-
       15 for more detail.)  If it is still above the action level,  it must complete the next 6
       months with  no  violation of WQPs in order to return to compliance.

Q:     Has EPA approved field test kits for WQPs?
State Implementation Guidance for the LCKMR          IV-10                                  October 2001

-------
A:     Yes, EPA has approved field test kits for WQPs. This will help systems to more quickly
       obtain information about WQPs, determine excursions, and perform follow-up
       monitoring as needed.

13.     DEEM and DONE Milestones

Q.     What are the DEEM and DONE Milestones?

A:     The DEEM Milestone is a new milestone which indicates that the system has met
       certain criteria which exempts the system from further corrosion control treatment
       steps under the LCRMR other than continued Lead and Copper tap monitoring and
       water quality monitoring for those systems already having corrosion control treatment in
       place.   The specific criteria for classifying a system as "Deemed to be Optimized" is
       located in §141.81(b)(l)-(3).  These criteria are as follows: (b)(l) - a system serving
       50,000 or fewer people that has met the lead  and copper action levels during each of two
       consecutive 6-month monitoring periods; (b)(2) - any water system that optimized
       corrosion control treatment before December 7,1992, based on the state's  review of
       water quality parameters, report on evaluation and selection of OCCT, report on OCCT
       installation and maintenance, and tap samples;  and (b)(3) - a system with minimally
       corrosive water in its distribution system, that demonstrates for two consecutive 6-
       month periods that the difference between the 90th percentile tap water lead level  and
       the highest source water lead concentration is less than 0.005 mg/L.  Also, the LCRMR
       expand the definition to include systems whose source water lead levels are below the
       Method Detection Limit and whose 90th percentile lead level is <0.005 mg/L.

       The DONE Milestone is a new milestone  to indicate when a system has completed  all
       applicable requirements for corrosion control, source water treatment, and lead service
       line replacement.
Q:     What date should be reported for systems that meet the Done or Deem criteria on or before April
       11,2000?

A:     If a system meets the criteria for Done or Deem on or before April 11, 2000, EPA
       prefers that  the State report the actual date  that the State made this decision.  However,
       if the State believes reporting the actual date a system was deemed and/or done will be
       overly burdensome, it may instead report a date of April 11, 2000 for these systems.
       Where States choose not to use the actual date, EPA asks States to use April 11, 2000
       because this is the effective date for the LCRMR. Any system deemed and/or done
       beyond April 11, 2000 should use the actual  date the system meets the criteria.
Q:     When must a State report Done and Deem for systems that meet these criteria?

A:     EPA is requesting that States report by February 15, 2001, those systems the meet the
       Done and/or Deem milestone criteria by January 11, 2001. After January 11, 2001 the
       Done and/or Deem milestone is reported  within 45 days after the end of the quarter in
       which the State determined the system met the Done or Deem milestone criteria.
       Systems are required to begin reporting the LCRMR milestones by January 12, 2000.
State Implementation Guidance for the LCRMR          IV-11                                  October 2001

-------
Q:     Must the State report that a system is Undone in the quarter following the quarter in which it
       becomes aware of this fact, or should it wait until the system meets the Done criteria?

A:     The end date of the appropriate Done milestone should be modified to reflect that the
       system has become "Undone".  This  should be reported in the quarter following the
       quarter in which it becomes aware of this. When the system again becomes Done, a new
       Done milestone should be reported.

14.     Lead Service Line Replacement Milestone

Q:     Systems that fail to meet the lead action level after installing OCCT and/or SOWT must begin
       annual replacement of lead service lines (LSLs).  Should the begin date for the lead service line
       replacement (LSLR) milestone be the day it exceeds the action level, or the day after the end of
       the compliance period or monitoring period for which the exceedance occurred?

A:     If the designated monitoring period  is January to June (follow-up  or routine), the begin
       date would be the last sampling date within that period.

75.     Return to Compliance and Violation Reporting

Q:     A system is required to perform two consecutive 6-month rounds of initial tap monitoring, but only
       performs one round.  An initial tap M/R (51) violation is reported.  It later correctly performs an
       additional round.  Should return to compliance be reported for this 51 violation.

A:     No. The system must perform two consecutive 6-month rounds of initial monitoring, in
       order to be considered to have returned to compliance.

Q:     When should Intentional No-Action be  reported, instead of return to compliance?

A:     In some cases, a requirement no longer applies to system because  it is at or below the
       lead and/or copper action level for a specified period of time.  In most of these cases, an
       Intentional No-Action should be reported, instead of return to compliance.  Refer to the
       table on page IV-15  for more detail.

Q:     What dates should be  used for violation begin and end dates?

A:     For all LCRMR violations except WQP M/R and  noncompliance with its OWQPs, the
       violation begin date  is the day after the end of the monitoring period. The end date is
       December 31, 2015.  For WQP M/R  and OWQP noncompliance violations, the begin
       and end dates reflect the actual monitoring period.

Q:     Can States continue to report compliance period begin and end dates for violations as they do
       now, and let SDWIS/FED  determine new begin and end dates based on these data for the
       noncompliance period?

A:     States may continue to report compliance begin and end dates as they currently do until
       the 2002 deadline. SDWIS/FED  will replace the  end date with the defaulted violation
       end date of 12/31/2015.  However, because these  violations are characterized by the
       period of noncompliance, which begins the day after the due date of the requirement,
State Implementation Guidance for the LCRMR           IV-12                                   October 2001

-------
       SDWIS/FED is not able to determine the begin date of the violation period because the
       timing of many requirements are triggered on the completion of the previous
       requirement.  Therefore, by the 2002 deadline, if not before, the state needs to report
       the begin of the violation period as described in the reporting guidance.

Q:     What date should be reported for the noncompliance period begin date for a system on annual or
       reduced monitoring?  Should it be the first day after the end of the 4-month monitoring period, or
       should it be the first day after the end of the 1-year, 3-year, or 9-year compliance period?

A     The noncompliance period begin date should be the first day after the end of the
       respective 4-month monitoring period, rather than the first day after the end of the
       respective compliance period.

Q:     Small and medium systems with exceedances must submit treatment recommendations to the
       State within six months after the end of the compliance period for which they had an exceedance.
       Large systems  are assumed to include the recommendations with the study that is due within 12
       months.
       a.  If the State has decided to make the recommendation on behalf of a small or medium
           system, but fails to do so within 6 months, should a violation be reported?
       b.  If a small/medium system is required to conduct a study, is the system still required to submit
           a separate recommendation?

A.     a.  The system is responsible for making treatment recommendations. Even if the
           State decides to make the recommendation on behalf of the system a violation
           should be reported because a specific rule requirement was not met.
       b.  Yes,  The recommendation  is required to make the determination of whether a
           study will be required.  The recommendation is due within 6 months after the  end of
           the compliance period for which the exceedance occurred and the study is  due
           within 12  months if the State designates a study is to be conducted.

Q:     A system is required to replace 7 percent of its LSLs annually starting January 1, 2000, but fails
       to do so in 2000. It then replaces 7 percent by August 15, 2001, and another 7 percent by
       December 31, 2001. How should this be reported?

A:     The system would have a LSLR violation with begin date of January 1, 2001, with  an
       associated RTC of August 15, 2001.

Q:     A system is required to replace 7 percent of its LSLs each year.  In the first year, it replaces 5
       percent.  In the second year, it replaces 5 percent.  It performs lead and copper tap monitoring
       annually, and is below the lead action level for two consecutive years. What should be reported?

A:     The system would incur a LSLR violation for the first year. It would not incur a LSLR
       violation for the second year, because it was below the lead action  level for two
       consecutive periods and can stop replacing LSLs. This system would be considered
       RTC for the first year when 2 percent of LSLs were replaced in Year 2.
Q:     How many violations should be reported for LSLR?  One violation per year? Multiple violations?
       Distinguish between violations for failure to replace lines from partial LSLR ones?
State Implementation Guidance for the LCRMR           IV-13                                   October 2001

-------
A:     One violation should be reported for any and all violations in a given year of
       replacement. Remember that the first year of lead service line replacement begin on
       the date the action level was exceeded in samples collected after corrosion control
       treatment or source water treatment was installed (whichever occurs in later). The
       system is considered to have returned to compliance when all requirements are fulfilled
       and the end of the replacement year arrives or when the system meets the lead action
       level in tap samples for two consecutive compliance periods.

16.     Changes in Population Served

Q.     In the event a medium-size water system on reduced monitoring experiences an increase in
       population bumping it into the large-size category, what must it do to comply with the LCR?

A:     Although the January 1, 1997 deadline for large systems to complete installation of
       corrosion control treatment has passed, the water system should follow the compliance
       steps and time frames  provided in the rule for large systems (e.g., the system would
       have four years to install corrosion control).  However, a system that can demonstrate
       that it is deemed to have optimized corrosion control under §141.81(b)(3) would not be
       required to conduct a study, install corrosion control treatment, or collect WQPs.  The
       system would be expected to comply with all LCR monitoring and reporting
       requirements for large systems.
A     In the event a large-size water system with State-established water quality control parameters
       experiences a drop in population and thus becomes a medium system, can the system discontinue
       WQP monitoring?

A.     If the water system is at or below the action level, then the State may allow the system
       to discontinue monitoring for WQPs. However, if the water system exceeds the action
       level, then it must continue monitoring for WQPs.

Q:     If a small water system that is on annual reduced monitoring becomes a medium system, must it
       perform semi-annual monitoring?

A:     No.  It may remain on annual reduced monitoring, as long as the system continues to
       maintain lead and copper 90th percentile levels at or below the action levels. However it
       must increase its number of required samples according to §141.86(c).  Additionally, the
       system would report all 90th percentile values for lead, as is required for medium-sized
       systems under the LCRMR.

17.     Public Education Requirements

Q:     If a system has a public education violation, but in a subsequent period, the 90th percentile lead
       level is at or below the lead action level, is the system still required to conduct public education?

A:     Yes, the system must still conduct one more round of public education in order to RTC.


Q:     What is the reasoning for requiring a system to conduct public education after lead levels are at or
       below the action level?  It  seems like an unnecessary effort, since systems are required to notify
State Implementation Guidance for the LCKMR          IV-14                                   October 2001

-------
       the public of lead exceedances or violations through public notification (PN) and the consumer
       confidence report (CCR).

A:     Although the PN and CCR rules also require that the system notify the public of
       problems, by providing health effects language (PN & CCR), and exceedances (CCR),
       public education requires the system to notify the public more quickly and is distributed
       to a wider audience, than would be required by PN and CCR.
Q:     Can the CCR be used to satisfy some of the requirements for public education?

A:     The system can satisfy the annual delivery requirement for those customers that
       receive water bills if the system includes the mandatory public education language in its
       CCR and the CCR is delivered  no later than 12 months from the last time the system
       provided public education.
Q:     Are the semi-annual and annual periods for performing public education considered to start on the
       day after or 61 days after the end  of the compliance period for which the exceedance occurred?

A:     The semi-annual and annual periods for performing public education start 61 days after
       the end of the compliance period for which the exceedance occurred.
