National Primary Drinking Water Regulations for Lead and Copper: 
Short-Term Regulatory Revisions and Clarifications

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing seven targeted regulatory changes to the 
National Primary Drinking Water Regulations (NPDWR) for lead and 
copper. This proposal strengthens the implementation of the Lead and 
Copper Rule (LCR) in the following areas: monitoring, treatment 
processes, customer awareness, and lead service line replacement. These 
changes will provide more effective protection of public health by 
reducing exposure to lead in drinking water. The proposed changes do 
not affect the basic requirements of the LCR, the lead or copper 
maximum contaminant level goals, or the lead and copper action levels.

DATES: Comments must be received on or before September 18, 2006. Under 
the Paperwork Reduction Act, comments on the information collection 
provisions must be received by OMB on or before August 17, 2006.

II. Background

A. Reason for This Rulemaking

    The purpose of the Lead and Copper Rule (LCR) is to protect 
populations from exposure to lead and copper in drinking water and 
reduce potential health risks. Recent high profile incidences of 
elevated drinking water lead levels in the District of Columbia 
prompted EPA to initiate a comprehensive national review of the LCR to 
evaluate the implementation and effectiveness of the rule. EPA began 
the review to determine the following: were drinking water lead levels 
elevated nationally; did a large percentage of the population receive 
water that exceeded the Lead Action Level; did a significant number of 
systems fail to meet the action level; how well has the existing LCR 
worked to reduce drinking water lead levels; and has the rule 
implementation been effective especially with respect to monitoring and 
public education requirements. EPA gathered the information for the 
review through a series of stakeholder workshops in late 2004; an 
evaluation of monitoring data; and an evaluation of LCR implementation 
by States and water utilities.
    As a result of the national review and workshops, EPA released a 
Drinking Water Lead Reduction Plan in March 2005 which identified nine 
actions to improve implementation of the rule. EPA has consolidated 
several of the Plan's actions into the seven proposed changes described 
in section III of this proposal. These changes to the rule are intended 
to strengthen in the short-term the implementation of the LCR in the 
areas of monitoring, treatment processes, customer awareness, and lead 
service line replacement. Some of the regulatory changes identified in 
EPA's review clarify the intent of the original LCR for provisions that 
may not have been sufficiently clear, while others revise LCR 
requirements in light of the recent experiences in the District of 
Columbia and elsewhere. The changes proposed are expected to enhance 
protection of public health through a reduction in lead exposure.
    EPA has also identified a number of issues that will be considered 
for future revisions to the rule. These issues require additional data 
collection, research, analysis and/or stakeholder involvement to 
support decisions. The issues include, but are not limited to, 
requirements for consecutive systems, monitoring, and lead service line 
replacement requirements. This proposal does not amend the portion of 
the regulations related to copper, however provisions addressing copper 
will be considered for future revisions to the rule. EPA will propose 
any future regulatory changes under a separate regulatory action.

B. Regulatory History

    EPA promulgated maximum contaminant level goals (MCLGs) and NPDWRs 
for lead and copper in 1991 (56 FR 26460, June 7, 1991d). 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 
community water systems (CWSs) and non-transient non-community water 
systems (NTNCWSs) to optimize corrosion control in their distribution 
systems and conduct periodic monitoring.
    The rule requires systems to optimize corrosion control to prevent 
lead and copper from leaching into drinking water. Large systems 
serving more than 50,000 people were required to conduct studies of 
corrosion control and install state-approved optimal corrosion control 
treatment by January 1, 1997. Small and medium systems are required to 
optimize corrosion control when monitoring at the consumer taps shows 
action is necessary.
    To assure corrosion control treatment technique requirements are 
effective in protecting public health, the rule also established an 
Action Level (AL) of 15 ppb for lead and 1300 ppb for copper in 
drinking water. Systems are required to monitor a specific number of 
customer taps, based on the size of the system. If lead concentrations 
exceed 15 ppb in more than 10% of the taps sampled, the system must 
undertake a number of additional actions to control corrosion and 
inform the public about steps they should take to protect their health.
    The LCR has four main functions: (1) Require water suppliers to 
optimize their treatment system to control corrosion in customers' 
plumbing; (2) determine tap water levels of lead and copper for 
customers who have lead service lines or lead-based solder in their 
plumbing system; (3) rule out the source water as a source of 
significant lead levels; and (4) if action levels are exceeded, require 
the suppliers to educate their customers about lead and suggest actions 
they can take to reduce their exposure to lead through public notices 
and public education programs. If a water system, after installing and 
optimizing corrosion control treatment, fails to meet the Lead Action 
Level, it must begin replacing the lead service lines under its 
ownership.
    EPA proposed minor revisions to the LCR (LCRMR) in 1996 (60 FR 
16348, U.S. EPA, 1996b) and finalized these minor revisions on January 
12, 2000 (65 FR 1950, U.S. EPA, 2000a). These minor revisions 
streamlined the requirements of the LCR to promote consistent national 
implementation and reduce the reporting burden on affected entities. 
These minor revisions also addressed the areas of optimal corrosion 
control demonstrations, lead service line replacement requirements, 
public education requirements, monitoring requirements, analytical 
methods, reporting and recordkeeping requirements, and special primacy 
considerations. The LCRMR did not change the action levels, MCLGs, or 
the rule's basic requirements.

C. Impacts of This Proposal

    This proposal will further strengthen protection of the public from 
exposure to lead and copper via drinking water by enhancing the 
implementation of the LCR in the areas of monitoring, customer 
awareness, and lead service line replacement. This action also 
clarifies the intent of some unclear provisions in the LCR. The 
regulatory revisions proposed today impose costs associated with State 
and system review of the regulatory changes, State review of system-
level changes to treatment plans, system reporting and monitoring, and 
public education. EPA has estimated the economic impacts for each of 
the regulatory changes, which will have direct and indirect costs 
associated with them. A detailed description of these impacts is 
provided in Section IV, Economic Analysis, of this proposal and in the 
Economic Analysis support document.

III. Proposed Regulatory Revisions to the Lead and Copper Rule

    This section describes the proposed clarifications and revisions to 
the Lead and Copper Rule. This section also describes issues and 
potential changes the Agency is requesting comment upon. Sections A 
through G describe changes proposed and alternatives for which the 
Agency is requesting comment. Section H describes several potential 
changes for which the Agency is soliciting comment.

A. Minimum Number of Samples Required

1. What Is EPA Proposing?
    EPA proposes to clarify the number and location of samples required 
for the smallest systems in Sec.  141.86(c) of the LCR. The 1991 LCR 
established a minimum number of sites required for

[[Page 40831]]

lead and copper tap monitoring based on system population size. EPA's 
proposal maintains five samples per monitoring period as the minimum 
number of samples required for systems serving fewer than 100 people.
2. Why Is EPA Proposing This Clarification?
    EPA is proposing this clarification to reduce confusion with 
respect to this provision of the rule. EPA considered the issue of 
sample size extensively in the 1991 rule. EPA considered all concerns 
regarding the number of samples that should be taken and explained the 
rationale for the number of samples in the Preamble to the 1991 Final 
Rule. Due to the high variability in lead and copper levels, EPA 
explained that it was necessary to take more samples than required in 
other rules in which the variability is not as high. In the 1991 
preamble, EPA also recognized the fact that sampling all households was 
not feasible and sought to balance this concern with the need for more 
samples to capture variability among lead levels. Specifically, the 
preamble stated: ``EPA believes that the number of samples required in 
the final rule sufficiently accounts for the variability in lead and 
copper levels, and reflects system-wide contaminant level 
distributions.'' (56 FR 26460 at 26523, U.S. EPA, 1991b); ``The 
requirements of the final rule seek to strike a balance between the 
competing needs of ensuring the representativeness of sampling results 
and ensuring that the sampling requirements are reasonable and 
implementable by public water systems.'' (56 FR 26460 at 26524, U.S. 
EPA, 1991b).
    In the preamble to the 1991 Rule, EPA also addressed concerns about 
the high costs to small systems of implementing the minimum number of 
samples requirement as follows: ``EPA understands commenter's concerns 
with the potentially high costs of sampling for small systems but 
believes the increased number of samples is necessary to ensure that 
lead and copper levels are reasonably well represented.'' (56 FR 26460 
at 26524, U.S. EPA, 1991d); ``For most systems, collecting more samples 
will be far less expensive than undertaking corrosion control or source 
water treatment, which they could otherwise be required to install 
based on an inappropriately small sample size.'' (56 FR 26460 at 26524, 
U.S. EPA, 1991d).
    In the preamble to the 2000 minor revisions, EPA revisited the 
question of the appropriate number of samples. The 2000 preamble 
clarified that even if a system did not have enough high-risk sites to 
meet the minimum number of samples, the system must take the required 
minimum number of samples. The 2000 Preamble again explains EPA's 
rationale for choosing the minimum number of samples, stated as 
follows: ``The number of samples specified for initial monitoring, 
follow-up monitoring and reduced monitoring was established to 
sufficiently account for variability of lead and copper at taps while 
at the same time being reasonable for a system to implement.'' (65 FR 
1950 at 1970, U.S. EPA, 2000a).
    Even with the explanations in the 1991 and 2000 preamble, there 
continues to be some confusion about the minimum number of samples 
required. EPA hopes to clarify this issue further with these revisions. 
In the 1991 rule, the term ``site'' is used to refer to the number of 
samples collected. However, there has been confusion as to whether site 
refers to taps or samples. EPA is proposing additional regulatory 
language to clarify that water systems with fewer than five taps must 
sample all taps at least once and repeat sampling at some taps in order 
to collect the minimum number of samples required. EPA believes this 
approach will provide an accurate representation of the lead level. 
Because lead levels may change over time, EPA believes this sampling 
approach will give a system the most accurate picture of its water 
quality. EPA further defines the taps in this clarification to be 
``taps used for human consumption'' in order to ensure that samples are 
taken from taps which would pose the highest risk for exposure to lead, 
rather than from a tap which is not used for drinking, such as an 
outside hose bib or utility sink.
3. How Does the Proposed Change Differ From the Current Requirement?
    The proposal does not alter current requirements. This is a 
clarification of the minimum number of samples requirement and does not 
represent a change in rule requirements or EPA policy.
4. What Issues Related to This Proposed Change Does EPA Request Comment 
On?
    While EPA is proposing to retain the five-sample minimum, EPA is 
also soliciting comment on an alternative which would specify that 
NTNCWSs with fewer than five taps used for human consumption would only 
be required to collect one sample per available tap used for human 
consumption. Under this alternative, the highest sample value would be 
compared to the action level, rather than an average of the two highest 
results. EPA is requesting comment: (1) On whether this alternative 
provides equal or greater protection than the proposed change, (2) on 
whether the alternative sampling requirement should be allowed only 
when the State determines that the system's historical monitoring data 
demonstrate the system is reliably and consistently below the action 
level.
    EPA consulted with representatives of five State drinking water 
programs in the development of this proposal. The representatives of 
the State drinking water programs disagreed with the proposed 
clarification to the regulations described in Section III.A2 above. The 
State representatives proposed this alternative change to the 
regulatory language. State drinking water program representatives have 
argued that, while it may make sense to collect a minimum number of 
samples for larger community water systems (CWSs) so that there would 
be relative confidence in the results being representative of the 
system as a whole (due to variability), this does not apply to a system 
where 100 percent of the available taps are being tested. These State 
drinking water program representatives provided the following four 
reasons for their support of the alternative approach in lieu of this 
proposed clarification.
    First, sampling at 100 percent of available taps will provide a 
high level of confidence that the sample results are representative of 
levels in the system, since the whole universe of available sampling 
sites is being sampled during each monitoring period.
    Second, in the event that a system with fewer than five taps has 
only one single tap that exceeds the action level, taking a total of 
five samples can easily result in the system not having an Action Level 
(AL) exceedance (and therefore not needing to solve a lead problem), 
because the 90th percentile is calculated by averaging the two highest 
samples when there are five samples. When a system takes fewer than 
five samples, a single sample above the AL would be considered an AL 
exceedance under the alternative to this proposal.
    Third, sampling each tap at systems that have fewer than five 
better represents variation over time in these systems than does the 
sampling for larger systems, since the same sites are sampled 
repeatedly (every monitoring period). Larger CWSs frequently have to 
change monitoring locations because consumers do not allow the system 
employees access to their homes on a repeated basis. Monitoring at 100 
percent of the same sites over time (at NTNCWSs) would catch any 
changes in plumbing materials introduced over

[[Page 40832]]

time, as well as account for any variability at these sites over time.
    Fourth, the alternative option would continue to provide robust 
protection for the most vulnerable populations, such as schools and 
childcare facilities, since all taps would be sampled. For example, if 
a preschool has a tap that exceeds the Lead Action Level, teachers 
would know not to use that tap to provide water to children for 
consumption, and the system would be required to address that issue 
immediately.
    EPA requests comment upon the alternative option including the four 
reasons described above and any other information that should be 
considered in evaluating this alternative to the proposed change.

B. Definitions for Compliance and Monitoring Periods

1. What Is EPA Proposing?
    EPA is proposing a number of clarifications throughout the LCR to 
clearly explain when compliance and monitoring periods begin and end.
2. Why Is EPA Proposing This Change?
    EPA is proposing clarifications regarding monitoring and compliance 
periods in order to clarify the meaning of these terms and to address 
two issues. The term ``compliance period'' is defined in Sec.  141.2 as 
a three-year calendar year period within a nine-year compliance cycle. 
The term ``monitoring period'' refers to the specific period within the 
compliance period in which a water system must perform the required 
monitoring (e.g., June-September).
    The first issue concerns the timing of actions following a lead or 
copper action level exceedance. For systems on reduced monitoring, they 
must monitor either once during each calendar year or once during each 
three-year compliance period. The monitoring period is from June to 
September or some other four-month period during normal operation when 
the highest lead levels are most likely to occur. Under the current 
regulations, some systems have been uncertain about when a system is 
determined to have exceeded the action level and the corresponding 
deadlines for completing corrosion control studies, lead service line 
replacement and public education (e.g., end of December or the end of 
September for systems monitoring June to September). This change would 
clarify that the system would be determined to be exceeding the action 
level as of the date on which the monitoring period ended (e.g., on 
September 30). This clarification is intended to ensure that the system 
and the State begin actions to reduce exposure, such as corrosion 
control, public education for lead and/or lead service line 
replacement, as soon as possible. The deadlines for completing these 
follow-up activities would be calculated from the date the system is 
determined to be exceeding the action level (end of the monitoring 
period).
    The second issue concerns the timing of samples that should be 
taken during the three-year compliance period for systems on triennial 
monitoring. This proposal would require samples to be taken during four 
consecutive months within the compliance period, not over multiple 
years. This requirement would assure that States and systems have an 
accurate assessment of the effectiveness of corrosion control. Under 
this requirement, samples will need to be taken during four consecutive 
months, during the three-year period. For most systems, this will mean 
monitoring during June to September during one of the three years in 
the three-year compliance period. For systems where the State has 
approved some other four-month period, all samples must be taken during 
that four-month period. Sampling during a short, fixed time period will 
allow the system to more accurately evaluate the effectiveness of the 
corrosion control treatment than would collecting the same number of 
samples over a three year period.
    We are also proposing that systems on triennial monitoring be 
required to conduct their monitoring every three years. Systems would 
therefore not be allowed to monitor during Year 1 of the first 
compliance period and during Year 3 of the second compliance period 
because that would mean five years would have passed between monitoring 
rounds. A similar change is also proposed for small systems with 
monitoring waivers to ensure that they monitor every nine years.
3. How Does the Proposed Change Differ From the Current Requirement?
    EPA is proposing clarifications of the terms, ``monitoring period'' 
and ``compliance period.'' EPA also proposes to revise a number of 
sections in the LCR to more precisely specify when the ``start date'' 
for the compliance calendar occurs. These changes clarify existing 
language rather than changing any requirements of the rule. These 
clarifications will ensure that corrosion control, public education, 
and/or lead service line replacement are started in a timely fashion in 
order to reduce exposure to lead. EPA also proposes revisions that will 
make it clear when systems may begin reduced monitoring as well as when 
they need to resume more frequent monitoring. Again, EPA is not 
changing requirements but rather making sure the current requirements 
are clear and are consistently implemented.
    EPA is also proposing that systems on triennial monitoring must 
monitor during one four-month period (called the ``monitoring 
period''). EPA is further proposing that systems on triennial 
monitoring monitor every three years, so that the start of the next 
round of monitoring is based on the previous round of monitoring. 
Systems would not be allowed to monitor in Year 1 of one round of one 
three-year compliance period and Year 3 of the next three-year period, 
since that would allow five years between rounds of monitoring. This 
same approach would also be applied to the nine-year cycles for systems 
with a monitoring waiver.
4. What Issues Related to This Proposed Change Does EPA Request Comment 
On?
    EPA is requesting comment on the clarifications throughout the rule 
regarding the terms monitoring period and compliance period. EPA also 
requests comments on other sections of the LCR that may need 
modification to clarify when actions are required to begin or be 
completed. In addition, EPA requests comment on the appropriateness of 
requiring systems on reduced monitoring to take all of their required 
samples during one four-month period in order to evaluate the 
effectiveness of the corrosion control treatment.

C. Reduced Monitoring Criteria

1. What Is EPA Proposing?
    EPA is proposing to disallow water systems that exceed the Lead 
Action Level from initiating or remaining on a reduced lead and copper 
monitoring schedule based solely on the results of their water quality 
parameter monitoring. This proposed change would modify the reduced 
monitoring provisions in Sec.  141.86(d)(4), specifically subsections 
(ii) , (iii) and (iv). These sections discuss when small and large 
water systems may reduce the required number of lead and copper samples 
in accordance with paragraph (c) of Sec.  141.86.
2. Why Is EPA Proposing This Change?
    EPA is proposing this change because the Agency believes that 
reduced monitoring should only be permitted in instances in which it 
has been demonstrated that corrosion control

[[Page 40833]]

treatment is both effective and reliable. Compliance with water quality 
parameters alone may not always indicate that corrosion control is 
effective.
    Monitoring lead levels is particularly critical for systems that 
are exceeding the Lead Action Level for several reasons. One reason is 
that it will assist systems in evaluating the effectiveness of 
corrosion control treatment. The 1991 LCR intended to allow systems 
eligibility for reduced monitoring even if they exceeded the lead or 
copper action level if they could demonstrate their corrosion control 
treatment was effective by meeting the State-designated water quality 
parameters. However, as shown by the events in the District of Columbia 
and as stated above, compliance with water quality parameters alone may 
not always indicate that corrosion control is effective, especially 
after a treatment or source change. Continued exceedance of the Lead 
Action Level may indicate that a particular method of corrosion control 
treatment is not effective for a particular system and this data may 
assist this system in finding a better alternative treatment. In 
addition, a system must know if it continues to exceed the Lead Action 
Level after installing corrosion control treatment in order to 
determine how long its lead service line replacement requirements 
remain in effect. Continued understanding of the range of lead levels 
detected within the system can also help the system implement an 
effective public education program.
    Secondly, primacy agencies may gain a more accurate picture of what 
lead levels in drinking water currently exist in their States. Many 
systems within States share water sources, have similar treatment 
technologies, and have similar materials in their distribution systems. 
States and other primacy agencies with knowledge of effective corrosion 
control for one system may be able to aid other systems within their 
jurisdiction in lowering lead levels in water. Having a more accurate 
characterization of lead levels in drinking water that exceeds action 
levels will also allow States and systems to better inform consumers 
and, thereby, create greater confidence in their efforts to reduce lead 
levels.
3. How Does the Proposed Change Differ From the Current Requirement?
    In addition to monitoring lead and copper levels at households, 
systems that exceed the lead and copper action level are required to 
monitor for water quality parameters established by the State. These 
water quality parameters include pH, alkalinity, and other parameters 
that reflect the method used to control the corrosivity of the water 
(e.g., phosphate levels). States establish acceptable ranges for these 
parameters for individual systems that must be maintained to assure 
compliance with the rule. Currently a system that meets the water 
quality parameter requirements is eligible to reduce the frequency of 
its lead and copper monitoring even if the system is currently 
exceeding the action levels. The proposed revision would limit the 
eligibility of reduced monitoring to only those systems meeting the 
Lead Action Level.
    Currently, paragraph (4) of Sec.  141.86(d) contains provisions for 
when water systems may reduce the monitoring frequency and the number 
of required lead and copper samples for systems of various sizes under 
both standard and reduced monitoring. Under subparagraph (ii) of this 
section, any water system that meets the water quality parameters 
specified by the State under Sec.  141.82(f) for two consecutive six-
month monitoring periods may reduce their monitoring to once per year 
and reduce the number of samples in accordance with paragraph (c) of 
Sec.  141.86 with written approval from the State. Under subparagraph 
(iii) of this section, any water system that meets these water quality 
parameters for three consecutive years of annual monitoring may reduce 
the monitoring frequency to once every three years with written 
approval from the State. The Agency is proposing to require that these 
systems must also meet the Lead Action Level over the specified time 
period as a criterion for reduced monitoring. For example, under 
subparagraph (ii) a system would have to meet the Lead Action Level and 
the State water quality parameters for two consecutive six-month 
monitoring periods in order to be eligible, with written approval from 
the State, to reduce its monitoring frequency to once per year and 
reduce the number of samples required in accordance with Sec.  
141.86(c). This proposed change will also require systems currently on 
reduced monitoring schedules that exceed the Lead Action Level during 
any four consecutive month monitoring period to resume sampling the 
standard monitoring number of sites under Sec.  141.86(c) each 
consecutive six-month monitoring period.
    It should be noted that subparagraph (i) of Sec.  141.86(d)(4) 
allows small- or medium-size water systems to reduce monitoring to once 
per year after meeting both the lead and copper action levels for two 
consecutive six-month monitoring periods. Subparagraph (iii) of the 
same section allows small- and medium-size systems to reduce monitoring 
from annually to once every three years after meeting both the lead and 
copper action levels for three consecutive years. The Agency is not 
proposing to change either of these requirements. Small- and medium-
size systems that meet both the lead and copper action levels may still 
reduce monitoring in the manner described in these sections without 
State approval.
4. What Issues Related to This Proposed Change Does EPA Request Comment 
on?
    EPA requests comment on the proposal to disallow water systems that 
are above the Lead Action Level from initiating or maintaining a 
reduced monitoring schedule based solely on the results of their water 
quality parameter monitoring.
    EPA did consider requiring that all systems meet both the lead and 
the copper action levels as criteria for eligibility for reduced 
monitoring. However, the Agency determined that copper issues should be 
considered as part of longer term revisions to the rule. EPA also 
believes that adding the copper action level requirement could impose a 
large monitoring increase on some small and medium systems that are 
currently limited in their ability to reduce copper below the action 
level (i.e., high alkalinity ground waters). For these systems, the 
States currently have flexibility in the existing rule to limit systems 
from proceeding to reduced lead and copper tap monitoring. Under 
subparagraphs (ii) and (iii) of Sec.  141.86(d)(4), a State may review 
and revise its determination to allow a system to proceed with reduced 
monitoring when the system submits new monitoring or treatment data, or 
when other data relevant to the number and frequency of tap sampling 
becomes available.

D. Advanced Notification and Approval Requirement for Water Systems 
That Intend To Make Any Change in Water Treatment or Add a New Source 
of Water That Could Affect the System's Optimal Corrosion Control

1. What Is EPA Proposing?
    EPA is proposing to amend Sec.  141.81(b)(3)(iii), Sec.  
141.86(d)(4)(vii), Sec.  141.86(g)(4)(iii), and Sec.  141.90(a)(3) to 
require water systems to obtain prior approval by the State primacy 
agency to add a new source of water or change a treatment process prior 
to implementation. The proposed regulatory language allows as much time 
as needed for water systems and States to consult before making those

[[Page 40834]]

changes. In addition to allowing this type of State discretion, EPA is 
currently developing a revised simultaneous compliance guidance 
document that can be used by the State to identify those situations 
where optimal corrosion control can be affected by changes in treatment 
or source water.
2. Why Is EPA Proposing This Change?
    In the 2000 revisions to the LCR, EPA published in the Federal 
Register a requirement that water systems notify the State primacy 
agency of the addition of a new source or treatment change no later 
than 60 days after implementing the change (65 FR 1950 at 1977, U.S. 
EPA, 2000a). When water systems make changes in their source water or 
treatment processes there could be unintentional effects on the water 
system's optimal corrosion control. The goal of this provision was to 
ensure that a water system maintained optimal corrosion control 
following changes in water quality resulting from a change in source or 
treatment process by providing the primacy authority an opportunity to 
review the change and its possible impacts on corrosion control. An 
example of change in treatment would be a switch in disinfectant.
    EPA now believes that this provision may not be adequate to ensure 
continued optimal corrosion control because the primacy agency review 
comes too late in the process. If a water system notifies the State 
primacy agency of changes that have already been made that could result 
in leaching of lead from plumbing components such as service lines, 
there may be little opportunity to minimize any anticipated problems 
with corrosion or prevent leaching from occurring. For this reason, EPA 
believes that such changes in treatment should be reviewed and approved 
by the State before they are implemented. Also, EPA believes that this 
proposed requirement would fit well into the existing State program 
plan review and approval requirements that are part of the State's 
primary enforcement responsibilities described in Sec.  
142.11(a)(2)(v).
3. How Does the Proposed Change Differ From the Current Requirement?
    Under the current requirement, water systems must simply provide 
written notification to the State within 60 days after the change in 
treatment or source has been made. This proposed regulatory revision 
requires that the notice of change be given in advance, and the State 
must approve the change. This gives water systems the opportunity to 
consult with their States and identify any measures that may be 
necessary to avoid or minimize potential problems with corrosion 
control. It also allows the State to design a monitoring program 
upfront, for those situations where it is necessary to ensure that 
corrosion control is being maintained adequately after the change has 
been made.
4. What Issues Related to This Proposed Change Does EPA Request Comment 
on?
    Although EPA believes the proposed regulatory revision is the best 
approach to address potential problems with corrosion control when 
treatment/source changes are made, EPA requests comment on a number of 
issues related to the proposal. First, EPA also considered the 
alternative of simply requiring advance notification to the State at 
least 60 days before the change. However, EPA decided to propose both 
prior notice and approval for two reasons. The first reason is that EPA 
could not determine a period for advance notice that would be 
appropriate for all changes; in some cases 60 days would be unnecessary 
(e.g., emergency changes to chemical feed systems) and in some cases it 
would be grossly insufficient (e.g., major system improvements such as 
installation of ion-exchange treatment). The second reason is that 
several States pointed out that they already require approval of such 
changes and thought such approval was necessary to ensure that optimal 
corrosion control would be maintained. EPA requests comment on the 
advanced notice (without approval) alternative and if commenters favor 
the alternative, EPA requests that commenters address the issue of how 
much time to provide (e.g., 60 days or another time period).
    The second issue on which the Agency would like public comment is 
what the phrase ``addition of a new source'' should mean for systems 
that mix water sources. For example, a water system can mix source 
water by going from 100% surface water to 50% ground water and 50% 
surface water on either a permanent or temporary (e.g., seasonal) 
basis. In this case, the mixing of source waters might or might not be 
considered an addition of a new source under the regulation. Similarly, 
a system may change the proportion of two sources such as moving from 
75% ground water and 25% surface water to 25% ground water and 75% 
surface water. These changes could also affect the water chemistry in a 
way that could impact corrosion control. From time to time, water 
systems may switch entirely from one source to another, such as going 
from 100% surface water to 100% ground water. EPA requests comment on 
(1) whether and when such changes should require prior approval and, 
(2) if approval should not be required for all such changes, what 
criteria should be used to distinguish these kinds of changes in source 
water from the source water changes that might affect corrosion control 
and need prior approval. Specifically, EPA requests public comment on 
whether the words ``source change'' should replace ``addition of a new 
source'' to describe a broader range of scenarios where source waters 
are changed in some way (e.g., mixing of source waters in different 
proportions) or if EPA should describe in more detail in rule or 
preamble language or guidance which types of changes require prior 
State approval.

E. Requirement To Provide a Consumer Notice of Lead Tap Water 
Monitoring Results to Consumers Who Occupy Homes or Buildings That Are 
Tested for Lead

1. What Is EPA Proposing?
    EPA is proposing to amend the public education requirements 
described in Sec.  141.80 (g) and add a new notification requirement at 
Sec.  141.85(d) that will require water systems to provide consumers 
who occupy homes or buildings that are part of the utility's monitoring 
program with testing results when their drinking water is tested for 
lead.
2. Why Is EPA Proposing This Change?
    Although some utilities may provide customers with the results of 
analyses conducted to meet requirements of the regulations, utilities 
are not currently required by EPA to notify occupants of the lead 
levels found in their drinking water. While samples are primarily 
collected to evaluate the effectiveness of corrosion control or to 
evaluate the corrosivity of the utility's water across the entire 
service area, the results of lead monitoring can provide useful 
information to the occupants of the household from which the samples 
were taken. Occupants can evaluate the results of lead tests for their 
drinking water and use that information to inform any decisions they 
might make to take action to reduce their exposure to lead in drinking 
water.
3. How Does the Proposed Change Differ From the Current Requirement?
    There are currently no provisions in the regulation that require 
water utilities to notify occupants of results of routine monitoring 
conducted to comply with the LCR. Community water systems

[[Page 40835]]

must collect samples from between five and 100 households to evaluate 
lead and copper concentrations. Non-transient, non-community water 
systems (including some schools that operate their own water system) 
must also collect samples. This proposed rule change would require 
systems to provide written notification to occupants of the households 
no later than 30 days after the utility learns the results for the 
samples collected from that household and to post or otherwise notify 
occupants of non-residential buildings of the results of the lead 
testing. This would include staff and parents of students for schools 
that are tested as non-transient non-community water systems.
    While there are no current requirements associated with 
notification of results of routine monitoring in the LCR, there are 
requirements for utilities to provide notice to homeowners when their 
water is tested in carrying out partial lead service line replacement. 
Section 141.84(d)(1) requires that utilities test water within 72 hours 
after the completion of partial replacement of a lead service line. The 
utility must report the results of the analysis to the owner and the 
resident(s) served by the line within 3 business days of receiving the 
results. Utilities must provide the information by mail or by other 
methods approved by the State. In instances where multi-family 
dwellings are served by the line, the water system has the option to 
post the information at a conspicuous location. This provision is not 
affected by the proposed rule change.
    The proposed language would require utilities to provide consumers 
(owners or occupants) at locations that were tested during routine tap 
monitoring pursuant to Sec.  141.86 with a consumer notice of the tap 
monitoring results as soon as practical, but no later than 30 days 
after the utility learns of the results. The notice must contain an 
explanation of the health effects of lead, list steps consumers can 
take to reduce exposure to lead in drinking water, provide contact 
information for the utility, include the Maximum Contaminant Level Goal 
(0 ([mu]g/L), the action level (15 ([mu]g/L) and an explanation of what 
these values mean. The results must be provided by mail or other 
methods approved by the State.
    EPA selected thirty days as the timeframe for notifying consumers 
of results because it is consistent with the notification time frame 
for a Tier 2 Public Notice and because it would better allow utilities 
sufficient time to generate a large number of notices for mailing at 
one time. The purpose for including the MCLG and the action level is to 
give consumers context as to their level of exposure in comparison to 
the goal and standard established for lead in drinking water. The MCLG 
is the level at which no known adverse health effects occur (with an 
adequate margin of safety) and the action level is the concentration of 
lead that States and systems use to determine if systems must install 
corrosion control treatment if they have not already done so, or if 
they must begin public education and lead service line replacement.
4. What Issues Related to This Proposed Change Does EPA Request Comment 
On?
    EPA seeks comment on several specific elements associated with the 
proposed requirements. Is 30 days sufficient time to provide 
notification, or is a shorter or longer time frame appropriate? Is it 
appropriate to include the MCLG and the action level and a brief 
explanation of their significance, or is there some other information 
that systems should or could be asked to provide that would be more 
useful to consumers in determining whether their tap monitoring results 
warrant further action to protect household members, especially 
children, from lead exposure through drinking water?
    Additionally, during development of the proposal, it was suggested 
that this provision would cause an undue burden on non-transient non-
community water systems. EPA believes it is important to include non-
transient non-community systems because many of them are schools or 
childcare facilities, which provide water to the population more 
susceptible to lead exposure. Given the flexibilities included in the 
proposal related to means of delivery, EPA seeks comment on whether 
this provision would cause an undue burden to non-transient non-
community water systems.

F. Public Education Requirements

1. What Is EPA Proposing?
    EPA is proposing to change the public education requirements of the 
Lead and Copper Rule (LCR) in the Code of Federal Regulations at Sec.  
141.85. The proposal would still require water systems to deliver 
public education materials after a Lead Action Level exceedance. EPA is 
proposing to change, however, the content of the message to be provided 
to consumers, how the materials are delivered to consumers, and the 
timeframe in which materials must be delivered. The changes to the 
delivery requirements include additional organizations that systems 
must partner with to disseminate the message to at-risk populations as 
well as changes to the media used to disseminate information to ensure 
that it reaches consumers when there is an action level exceedance.
    In addition to the changes to Sec.  141.85 for the LCR, EPA is also 
proposing a change to Sec.  141.154(d) for the Consumer Confidence 
Report (CCR) rule, which requires community water systems to send an 
annual report to billed customers containing information relevant to 
the quality of the drinking water provided by the system (63 FR 44512, 
August 19, 1998, U.S. EPA 1998a). EPA is proposing to change the CCR 
rule to require all community water systems that detect lead in their 
compliance monitoring samples to include information about the risks of 
lead in drinking water in the report on a regular basis.
2. Why Is EPA Proposing This Change?
    EPA is proposing to change the public education requirements of the 
LCR in order to improve compliance and ensure that consumers receive 
the information they need to appropriately limit their exposure to lead 
in drinking water. Because the sources of lead are frequently within 
the home and reduction of lead in drinking water is the responsibility 
of both the public water systems and the consumer, EPA wants to ensure 
that information is delivered and that it is meaningful and useful to 
the consumer.
    EPA identified compliance as an important issue during its review 
of LCR implementation. Based on EPA's review of state files, over 40 
percent of water utilities did not conduct the required public 
education; therefore the at-risk population did not get information 
they needed to reduce their exposure from lead in drinking water (Lead 
and Copper Rule State File Review: National Report, EPA, March 2006a) 
EPA believes the changes in this proposal better ensure that at-risk 
populations receive information quickly and are able to act to reduce 
their exposure. EPA also believes water systems will be better able to 
comply with these proposed requirements.
    During EPA's national review of the LCR, many stakeholders stated 
that the public education requirements needed improvement. In September 
2004, EPA held an expert workshop to discuss the public education 
requirements of the rule. A number of concerns were raised at this 
workshop about the effectiveness of the existing public education 
language and requirements. Workshop

[[Page 40836]]

participants stated that the mandatory language in the rule is too 
long, cumbersome, and complex to convey to the general public an 
understanding of the risk posed by lead in drinking water and an 
appropriate course of action. Public education must put the risk in 
context and convey to the public the appropriate sense of urgency for 
consumers to act to reduce exposure. In addition, workshop members 
called for public education messages to be tailored to those who are at 
highest risk for lead exposure. Many participants stated that the 
mandatory language and delivery requirements in the current rule were 
ineffective in providing useful and timely information to the public. 
(Summary from Public Education Workshop, U.S. EPA, 2004a).
    In order to address these concerns, the National Drinking Water 
Advisory Council (NDWAC), EPA's advisory body on the Safe Drinking 
Water Act, formed a working group to consider possible revisions to the 
public education requirements. The charge for the NDWAC Working Group 
was to (1) review the current public education requirements for lead in 
drinking water to make recommendations for improvements; (2) develop 
recommended revised language for communicating to the public the risk 
of lead in drinking water and how affected persons should respond; and 
(3) review and make recommendations for changes to the means of 
delivery of lead information to the public (70 FR 54375, U.S. EPA, 
2005).
    The NDWAC Working Group met in person four times between October 
2005 and April 2006. The Working Group was comprised of 16 individuals 
representing an array of backgrounds and perspectives. Collectively, 
these individuals brought into the discussion the perspectives of State 
drinking water agencies, environmental and consumer groups, drinking 
water utilities, small system advocates, State health officials, and 
risk communication experts.
    The NDWAC Working Group raised a number of concerns with the public 
education requirements of the LCR that are consistent with the concerns 
expressed at the 2004 workshop. The NDWAC Working Group recommended 
that the rule be modified to better ensure that information reaches the 
most vulnerable populations (e.g., pregnant women, infants and young 
children) or their caregivers. They also recommended changes to ensure 
that these consumers received information in a more timely manner and 
continued to receive information throughout any exceedance. They also 
recommended changes to ensure that the information is easy to 
understand and effective in informing affected consumers and 
encouraging parents or other caregivers to take actions to reduce 
exposure of infants and children to lead. In addition, the NDWAC 
Working Group recommended changes to make sure critical information 
reaches not only bill paying customers, but those consumers who live in 
apartments and other housing where residents do not receive bills.
    Finally, the NDWAC Working group was also concerned about the 
amount of time it may take to test water, get back the results, 
calculate the 90th percentile, and finally send out public education 
materials. They were concerned that an individual could be drinking 
water with high lead levels for months before knowing of the problem. 
As a result, they recommended changes to increase the timeliness of 
public education on lead in drinking water.
    The NDWAC recommendations are, in part, modeled after the public 
education information under two existing EPA rules, the CCR rule and 
the Public Notification Rule (65 FR 25982, U.S. EPA, 2000b). The NDWAC 
recommendations form the basis for the changes to Sec.  141.85 proposed 
in this rulemaking.
3. How Does the Proposed Change Differ From the Current Requirement?
    The public education requirements in this proposal differ in a 
number of ways from the current requirements of the LCR. This proposal 
still requires water systems to complete the public education 
requirement after a Lead Action Level exceedance, but changes the 
mandatory content of written materials, delivery requirements, and 
timing of when systems must complete all required activities. This 
proposal also changes the requirements for the language or content of 
written materials, giving water systems more flexibility to tailor the 
public education message to their community and situation. EPA believes 
these changes will make the public education program more effective. In 
addition, this proposal changes the delivery requirements in a number 
of ways. Water systems will be required to send written materials to 
additional organizations in an attempt to better reach at-risk 
populations. This proposal also requires the systems to do several 
additional activities but allows them to pick from a list of activities 
in order to do what is most effective for their community. This 
proposal requires that water systems maintain communication with 
consumers throughout the Lead Action Level exceedance by including 
information with every water bill; provide two press releases a year; 
and for larger systems, include information on their Web site. This 
proposal allows primacy agencies to give water systems more time to 
complete the additional activities and deliver water bills. Finally, 
this proposal includes changes to the Consumer Confidence Report to 
ensure consumers are aware of concerns about lead in drinking water.
a. Changes to the Mandatory Text of the Written Materials
    This proposal requires the system to continue to deliver written 
materials to all customers as well as a number of key organizations. 
However, EPA is proposing to change the content of the required written 
materials. Currently, Sec.  141.85 requires written materials to 
include mandatory language consisting of over 1,800 words describing 
health effects, lead in drinking water, steps to reduce exposure, and 
how to obtain additional information. Under this proposal, the 
mandatory language would be much shorter and easier to understand. The 
mandatory language would address essential topics such as the opening 
statement and health effects language. Community Water Systems and Non-
Transient Non-Community Water Systems would still be required to 
provide information on other topics, but the system may either use 
EPA's suggested language or their own words to explain these topics. 
EPA believes that this format will result in more effective public 
education materials.
    EPA does recognize that small systems do not have the resources to 
create their own language for the required topics, so EPA will provide 
language in guidance that systems can use to explain all of the 
required topics in the regulation. For example, EPA is giving systems 
more flexibility in the language they use for flushing instructions, 
yet for systems that do not have data to identify clear flushing 
instructions, EPA will suggest flushing times to share with customers.
b. Changes To Better Reach At-Risk Populations
    EPA is proposing to add organizations to the list of recipients of 
the public education materials in order to increase the likelihood that 
the most vulnerable populations or their caregivers will receive the 
information they need to reduce their exposure to lead in drinking 
water. EPA is proposing to add licensed childcare centers, preschools, 
Obstetricians-Gynecologists and Midwives to the current list of 
organizations to which a system must deliver information. In addition, 
EPA is

[[Page 40837]]

proposing a new requirement that systems include a cover letter with 
the printed materials that they send to these organizations to explain 
the importance of sharing this information with their customers/
patients. This proposal is designed to help ensure that the information 
reaches non-bill paying customers; these customers may be reached 
through these organizations if the organizations are provided with the 
necessary information and encouraged to share the task of improving 
public awareness.
    While it is important for this information to get to all of these 
organizations, EPA believes that the local health agencies play an 
important role in making sure consumers who are most vulnerable receive 
the information they need to reduce their exposure to lead in drinking 
water. In order to make sure the local health agencies know about the 
Lead Action Level exceedance, EPA is proposing to require systems to 
directly contact (e.g., phone, in person, etc.) the local health agency 
rather than simply delivering brochures to this organization. By 
directly contacting the local health agency, utilities can enlist the 
health agency's support in disseminating information on lead in 
drinking water and the steps that vulnerable populations can take to 
reduce their exposure.
    In addition to using organizations to disseminate information to 
at-risk populations, EPA is also proposing that systems complete 
additional activities from a list of options. The list of additional 
activities that systems can choose from includes:
     Public Service Announcements
     Paid advertisements such as newspaper or transit ads
     Information displays in public areas such as grocery 
stores
     Using the internet or email to disseminate information
     Public meetings
     Delivery to every household (not just bill paying 
customers)
     Individual contact with customers such as door hangers
     Provide materials directly to multi-family homes and 
institutions
     Other methods approved by the primacy agency
    This proposal requires that systems serving 3,300 people or above 
be required to do three additional public education activities from the 
list of possible items and systems serving 3,300 or fewer individuals 
must do one additional activity from this list. The system must work in 
consultation with the primacy agency to ensure the content of each of 
these additional activities is appropriate. EPA is proposing that a 
system can choose three items from one, two, or three of these general 
categories. For instance, a system can do a series of paid 
advertisements if that is the most effective way to reach the target 
populations in their community.
    System, State and consumer representatives on the NDWAC Working 
Group all agreed that what works in one community does not always work 
best in another community. In order to make the public education as 
effective as possible, EPA is proposing to give systems some 
flexibility in how they deliver their public education materials. They 
are still required to disseminate information to people served by their 
system, but they have some flexibility in how they complete their 
program. For instance, a large system in an urban area may choose to 
use a public service announcement and paid advertisements to reach 
consumers, while a system in a rural area may find the best way to 
reach customers is through displaying information in frequently visited 
public areas or public meetings.
    In the current regulation, small systems are able to limit their 
distribution to only those facilities and organizations frequented by 
the most vulnerable populations. While systems serving less than 500 
people may do this without approval from the state, systems serving 
501-3,300 may limit their distribution if they receive written approval 
from the state. This proposal changes this so that all small systems 
serving 3,300 or fewer people may limit their distribution to only 
those places frequented by the most vulnerable populations without 
written approval from the state.
c. Changes To Help Systems Maintain Communication With Consumers 
Throughout the Exceedance
    In order to ensure continued contact with consumers, EPA is also 
proposing that systems include information in or on the water bill as 
long as there is an exceedance of the Lead Action Level. EPA recognizes 
that this requirement can be difficult for some systems that are unable 
to print messages on their bills, so there is a provision to allow 
systems to work with their primacy agency to deliver this information 
in a different way.
    Another way that this proposal encourages continuous communication 
with consumers is by requiring systems with a population greater than 
100,000 to put the public education information on their Web site. 
Under the proposal, this information must remain on the Web site until 
the system tests below the Lead Action Level.
    Currently, systems that exceed the Lead Action Level must issue a 
press release. EPA is proposing to require that systems distribute two 
press releases per year in order to ensure systems are maintaining 
communication with their customers. The systems must send the press 
releases to the major newspapers and TV and radio stations which serve 
the population served by the water system. This is another way to reach 
consumers who do not receive water bills. In response to concerns about 
small systems' ability to complete this requirement, in this proposal, 
primacy agencies can waive the press release requirement if there are 
no media outlets that specifically target the population served by the 
system. In addition, this proposal removes the requirement for medium 
and large systems to provide two Public Service Announcements (PSA) per 
year.
d. Changes to the Required Timing of Completion of Public Education 
Requirements
    While this proposal would still require systems to complete most of 
their public education in 60 days, there is increased flexibility for 
the primacy agency to allow longer periods of time for completion of 
water bill delivery and the additional activities from the list of 
options. This proposal would allow more time so that a system could 
align its billing cycle with the public education requirements. EPA 
understands that many systems have a billing cycle which may begin 
within the 60 days time frame but not all customers would be billed at 
the same time. The primacy agency may allow the system to include 
information with their regular billing cycle even if this means some 
customers receive this part of the public education program a bit later 
than the 60-day window. In addition, EPA is proposing to allow the 
system to work with the primacy agency on a schedule to complete the 
additional items such as PSAs or advertisements. This is intended to 
encourage systems to pick the items from this list that will be most 
effective and will reach the most vulnerable populations rather than 
the items that are easiest and quickest to complete. In order to make 
sure that the public education program is effective, the primacy agency 
may allow the system to take a bit longer to complete these more 
complicated items. The system must still complete all other aspects of 
the public education program, such as delivering materials to 
organizations that work with at-risk populations, posting information 
on their Web site and submitting press releases within the 60 days. 
This will

[[Page 40838]]

ensure that customers receive some information as quickly as possible.
e. Changes to Consumer Confidence Reports
    The NDWAC suggested changes to the CCR rule to address the concern 
that materials may not be delivered immediately and therefore 
vulnerable populations may drink water with high levels of lead for 
months before knowing of the risk. Under current regulations, all water 
systems that detect lead above the action level in more than five 
percent of the homes sampled must include a short informational 
statement about lead in drinking water in their CCR. In this action, 
EPA is proposing that all Community Water Systems who detect lead above 
the method detection limit of 0.001 mg/L in their compliance monitoring 
samples provide information in their annual CCR on lead in drinking 
water. This approach is consistent with the CCR rule requirements for 
the other inorganic contaminants in Sec.  141.151, which is also based 
on the method detection limit. This short statement will help to ensure 
that all vulnerable populations or their caregivers receive information 
on how to reduce their risk to lead in drinking water at least once a 
year. In addition, the NDWAC recommended changes to the language in the 
informational statement to make the risk of lead in drinking water 
clear as well as to include basic steps on how to reduce exposure to 
lead in drinking water and where to go for more information. EPA is 
proposing these changes in this rule.
4. What Issues Related to This Proposed Change Does EPA Request Comment 
on?
    EPA is asking for comment on the proposed revisions to the public 
education requirements under the Lead and Copper Rule. In particular, 
EPA requests comment upon revisions to the mandatory language for 
written materials. EPA requests comment on the flexibility provided in 
the requirements for the content of written public education materials. 
EPA also requests comment on the shortened mandatory language and 
suggested language for other required topics. Do commenters believe 
this revised language is clearer and will be easier for consumers to 
understand? Is the proposed health effects language and information on 
steps consumers can take to reduce lead exposure useful to consumers? 
Should the language also indicate that exceedence of the action level 
at the 90th percentile tap reading does not mean that all consumers are 
exposed to elevated levels of lead? Do commenters have any concerns 
about compliance with the proposed content requirements? Should EPA 
require systems to submit their written materials to primacy agencies 
before distributing them? EPA also requests comment on whether or not 
systems should be required to modify their public education materials 
if the primacy agency determines it is not consistent with the 
mandatory language.
    The mandatory language includes a section on contacts for more 
information. This section includes a requirement for the system to 
include how to contact both the system and EPA. EPA requests comment on 
whether there should be a mandatory requirement to include the contact 
information for the State drinking water primacy agency. EPA is aware 
that a number of States adopt EPA drinking water regulations by 
reference and these States would not be able to insert a requirement 
for systems to provide State contact information. Would States who 
adopt by reference face a challenge encouraging customers to contact 
their office under the current proposal?
    EPA also seeks comment on the delivery requirements for the public 
education message. Will the changes to the delivery requirements make 
the public education program more effective at reaching the most 
vulnerable populations? Are there other delivery mechanisms EPA should 
consider? EPA is also interested in any studies or information 
commenters have on ways to reach the populations of concern.
    The delivery requirements in this proposal expand on the 
requirement that systems deliver public education materials to certain 
organizations such as schools, pediatricians, childcare centers, etc. 
EPA requests comment as to how a system that exceeds the Lead Action 
Level should determine to which of these organizations it must deliver 
materials. Should the system deliver materials to only organizations 
that are served by that system, all organizations in the county or 
other local government jurisdiction, or all organizations that provide 
service to the population served by the water system?
    EPA is proposing that Community Water Systems consult with the 
primacy agency to ensure the information they disseminate as part of 
the additional activities under Sec.  141.85(b)(2)(vi) is appropriate. 
EPA is interested in whether commenters believe this is too great a 
burden on the primacy agency. Should EPA determine the required content 
for these additional activities? If EPA should make this determination, 
do commenters have suggestions for what the content should be?
    EPA is interested in whether commenters agree that some water 
systems will need more than 60 days to complete delivery of water bills 
which include the public education information and the additional 
activities from the list (e.g., PSAs, paid advertisements, etc.)
    EPA also requests comment on whether this proposal adequately 
addresses the concerns of small systems. Many small systems have 
limited resources and limited technical capabilities. Will these 
systems be able to complete the requirements, and if so, will this make 
for an effective public education program in their communities?
    EPA also requests comment on the proposed modifications to the CCR 
rule requirements for lead. First, EPA requests comment on requiring 
systems that detect any lead to include language in their consumer 
confidence report. This requirement would be triggered for systems 
detecting lead above the method detection limit of 0.001 mg/L. EPA is 
interested in whether commenters think the criterion should be 
detecting lead above the practical quantitation level of 0.005 mg/L, or 
above some other level that may be more relevant for consumers in 
determining whether they should take any further action?
    Second, EPA requests comment as to whether the CCR is an effective 
way to reach the targeted populations before there is a major problem 
in a water system. Are there other vehicles for reaching these 
individuals that EPA should consider?
    Third, EPA requests comment upon the content of the informational 
statement to be included in the CCR for systems that detect lead or 
exceed the Lead Action Level. EPA requests comment on whether this 
language would be effective in raising the targeted populations' 
awareness of the effects of lead in drinking water and steps they can 
take to minimize exposure to lead. In particular, EPA notes that the 
proposed language is essentially the same whether the system has 
exceeded the action level or not. Should EPA develop language that 
communicates a greater urgency about taking further action in 
situations where the action level has been exceeded than in situations 
where it has not? EPA also notes that the language focuses on the 
household plumbing as the potential sources of lead in drinking water. 
EPA requests comment as to whether other potential sources of lead 
(e.g., service lines) should be identified for the consumer.

G. Reevaluation of Lead Service Lines Deemed Replaced Through Testing

1. What Is EPA Proposing?
    EPA is proposing to require water systems to reevaluate lead 
service lines classified as ``replaced'' through testing if they resume 
lead service line replacement programs. This would only apply to a 
system that had (1) initiated a lead service line replacement program, 
then (2) discontinued the program, and then (3) subsequently resumed 
the program. When resuming the program, this system would have to 
reconsider for replacement any lead service lines previously deemed 
replaced through the testing provisions in Sec.  141.84(c) during the 
initial program. This proposed change would add a subsection to the 
lead service line replacement requirements in Sec.  141.84(b) to 
include provisions for systems resuming lead service line replacement 
programs.
2. Why Is EPA Proposing This Change?
    Lead service line replacement is intended as an additional step to 
reduce lead exposure when corrosion control treatment is unsuccessful. 
The provision in Sec.  141.84(c), which allows systems to leave in 
place an individual lead service line if the lead concentration in all 
service line samples from that line is less than or equal to 0.015 mg/
L, is intended to maximize the exposure reduction achieved per service 
line replaced by avoiding the disruption and cost of replacing lines 
that are not leaching high levels of lead. However, samples taken from 
a lead service line pursuant to Sec.  141.84(c) cannot predict future 
conditions of the system or of the service line. Systems can 
discontinue a lead service line replacement program by meeting the Lead 
Action Level for two consecutive 6-month monitoring periods. Therefore, 
EPA is proposing that these systems reconsider any lines previously 
determined to not require replacement if they exceed the action level 
again in the future and resume the lead service line replacement 
program.
3. How Does the Proposed Change Differ From the Current Requirement?
    A system that exceeds the action level must replace at least seven 
percent of its lead service lines each year until it is under the 
action level for two consecutive 6-month monitoring periods. Currently, 
a system is not required to replace an individual lead service line if 
the lead concentration in all service line samples from that line are 
less than or equal to 0.015 mg/L. The proposed revision would continue 
to allow systems to determine if a lead service line does not require 
replacement in this manner. However, the proposal would not allow 
systems to consider such lines as permanently removed from the 
replacement program. This rule change would apply to a system that (1) 
exceeds the action level, (2) tests out one or more service lines, (3) 
brings lead levels below the action level for two consecutive 6-month 
monitoring periods and discontinues replacing lead service lines, and 
(4) later exceeds the action level again. That system would have to 
reinitiate lead service line replacement considering all lead service 
lines including those that had previously tested out of the replacement 
program under Sec.  141.84 (c). The system would divide the updated 
number of remaining lead service lines by the number of remaining years 
in the initial lead service line replacement program to determine the 
number of lines that must be replaced per year. Systems resuming lead 
service line replacement programs as detailed above would not have 15 
years from the date of recommencement and, thus, would not be able to 
restart the ``clock'' for their lead service line replacement program. 
Such systems would have to consider the number of years remaining as 15 
minus the number of years they had completed in their initial 
replacement program (i.e., a system resuming after conducting two years 
of replacement has 13 years in which to complete the program). In 1991, 
EPA established the maximum replacement schedule of 15 years for all 
systems. This was because the Agency believed that if systems were 
allowed to replace lead service lines as part of normal maintenance, it 
may take as long as 50 years before all of the problematic lead lines 
were replaced in some systems. EPA believed that it was necessary to 
accelerate the rate at which systems would otherwise replace lead 
service lines in order to ensure that public health is adequately 
protected (56 FR 26460 at 26507-26508, U.S. EPA, 1991d). Therefore, the 
Agency believes that systems that are exceeding the action level should 
have no more than 15 years to replace all of their lead service lines, 
as intended by the current rule.
4. What Issues Related to This Proposed Change Does EPA Request Comment 
on?
    EPA requests comment on the proposal to require water systems to 
reevaluate lead service lines classified as ``replaced'' through 
testing if they resume lead service line replacement programs.

H. Request for Comment on Other Issues Related to the Lead and Copper 
Rule

    The following subsection describes additional issues related to the 
Lead and Copper Rule for which the Agency is considering changes to 
regulations.
1. Plumbing Component Replacement
    Some water systems may choose to replace plumbing fixtures, pipes, 
and components to greatly reduce the amount of lead or copper in tap 
water to a level below the action level. Generally this approach only 
applies to water systems that have 100% ownership over the plumbing 
infrastructure; some schools and other institutions can fall into this 
category. The Agency believes that this type of strategy can be cost-
efficient and a more effective way to address corrosion of lead and 
copper. EPA is requesting comment as to whether plumbing replacement 
should be specifically defined as a corrosion control technique, or 
explicitly identified as an alternative to corrosion control 
optimization for small and medium systems.
    Small water systems can use fixture replacement with existing 
provisions of the lead and copper rule to become optimized. Under Sec.  
141.81(b)(1), a small or medium-size system is deemed to have optimized 
corrosion control if the system meets the lead and copper action levels 
during each of two consecutive six-month monitoring periods conducted 
in accordance with Sec.  141.86. Thus, non-transient, non-community 
water systems, where 100% of the plumbing fixtures and components are 
directly controlled by the system, could replace them and be optimized 
once the system met the action level for two consecutive six-month 
monitoring periods.
    Although water systems (typically non-transient non-community water 
systems) can replace pipes, fixtures and plumbing components to meet 
the lead or copper action level, this method of compliance is not 
specified in the LCR as a corrosion control technique. When a system 
exceeds the action level, it must initiate the treatment steps under 
Sec.  141.81(e) that require the evaluation of corrosion control 
options and the recommendation of optimal corrosion control treatment. 
The current regulations could be read to require a small or medium 
system to perform evaluations of the corrosion control techniques 
listed in Sec.  141.82(c)(1), even when the system is planning to 
replace plumbing components and is thus unlikely to install such 
corrosion control treatment. However, EPA

[[Page 40840]]

believes that there is sufficient flexibility under the current rule 
for systems that replace plumbing to qualify as optimized under Sec.  
141.81(b)(1) without having to undertake an unnecessary evaluation of 
corrosion control options. Under Section 141.81(e)(2), after an initial 
action level exceedance, the system has 12 months (or two monitoring 
periods) before the State makes a determination about requiring a 
corrosion control study. The plumbing replacement option, as a 
practical matter, is limited to small or medium non-transient, non-
community water systems; under Section 141.81(e)(2)(ii), where the 
State does not require a system to conduct a corrosion control study, a 
system has 24 months after the action level exceedance (or four 
monitoring periods) before the State specifies optimal corrosion 
control treatment. As a result, very small water systems could replace 
the plumbing and conduct monitoring to demonstrate that the system is 
below the action level for two consecutive six-month monitoring periods 
within this 24-month period, although to do this, they would have to 
complete the plumbing replacement within 12 months of exceeding the 
action level. The Agency is requesting comment on whether there is 
enough existing flexibility under the current rule for very small 
systems to optimize using plumbing replacement or whether EPA should 
consider defining plumbing replacement as a corrosion control technique 
or as an alternative to corrosion control for small and medium systems. 
In particular, the Agency requests comment on whether 12 months is 
sufficient time for a small or medium system to replace plumbing 
components. If EPA were to allow States to specify plumbing replacement 
as a treatment option for small and medium systems, the systems would 
then have 24 months to complete the replacement, rather than the 12 
months that they effectively have under the current rules.
    EPA believes that there are a number of questions that would need 
to be resolved before listing plumbing component replacement as a 
corrosion control technique or an alternative to corrosion control. 
What materials should be used for replacement materials, since ``lead-
free'' products still contain lead? What components would be replaced--
just end-point devices such as faucets or would it also include in-line 
devices, such as valves and water meters? What would be the enforceable 
water quality parameters for this alternative to corrosion control? How 
would excursions from the optimal water quality parameters be measured? 
If these techniques are listed under Sec.  141.81(c)(1) as corrosion 
control techniques, would all systems need to evaluate them as part of 
the corrosion control study? For systems that fail to meet the action 
level, would the State still need to specify the minimum pH values, 
even though the system may not be adjusting pH?
2. Point of Use and Point of Entry Treatment
    Another strategy for reducing the lead or copper levels below the 
action level would be the use of point of use (POU) or point of entry 
(POE) devices. As with plumbing replacement, EPA is requesting comment 
as to whether use of POU or POE devices should be specifically defined 
as a corrosion control technique, or explicitly identified as an 
alternative to corrosion control optimization for small systems.
    Both POU and POE devices are identified in the Safe Drinking Water 
Act (SDWA) as potential compliance technologies for small systems. In 
addition, the SDWA also lists a number of requirements for POU and POE 
devices if they are used as compliance technologies. These include: (1) 
POU and POE devices shall be owned, controlled and maintained by the 
public water system or by a person under contract to a public water 
system to ensure proper operation and maintenance and compliance with 
the treatment technique; (2) POU and POE devices must be equipped with 
mechanical warnings to ensure that customers are automatically notified 
of operational problems; and (3) if the American National Standards 
Institute (ANSI) has issued product standards applicable to a specific 
type of POU or POE treatment unit, individual units of that type shall 
not be accepted for compliance with a treatment technique requirement 
unless they are independently certified in accordance with such 
standards. The NSF/ANSI drinking water treatment unit standards do 
cover lead removal, so devices would need to be certified against one 
of the following standards: NSF/ANSI 53 Reduction Claims for Drinking 
Water Treatment Units--Health Effects, NSF/ANSI 58 Reduction Claims for 
Reverse Osmosis Drinking Water Treatment Systems, or NSF/ANSI 62 
Reduction Claims for Drinking Water Distillation Systems.
    One limitation with POE devices is that there can still be lead-
containing plumbing after the POE device. Faucets, solder joints, etc. 
could still contribute high lead levels, so this approach may not be 
successful if the water is corrosive.
    EPA believes that small systems can use POU devices, if they meet 
the SDWA requirements discussed above for their use, to comply with the 
lead and copper rule under existing provisions of the rule. Under Sec.  
141.81(b)(1), a small or medium-size system is deemed to have optimized 
corrosion control if the system meets the lead and copper action levels 
during each of two consecutive six-month monitoring periods conducted 
in accordance with Sec.  141.86. Thus, small water systems where POU 
devices are installed and meet the SDWA requirements could be optimized 
once the system met the action level for two consecutive six-month 
monitoring periods after their installation at all sites.
    Although small water systems can use POU devices to meet the lead 
or copper action level, this method of compliance is not specified in 
the current LCR as a corrosion control technique. As a result, the same 
issue arises as discussed above with respect to plumbing replacement. 
The current regulations could be read to require a small system to 
perform evaluations of the corrosion control techniques listed in Sec.  
141.82(c)(1) even when the system is planning to install POU devices 
(in accordance with all applicable requirements of the SDWA) and is 
thus unlikely to install such corrosion control treatment.
    EPA believes that there may be sufficient flexibility under the 
current rule for systems that use POU devices to qualify as optimized 
under Sec.  141.81(b)(1) without having to undertake an unnecessary 
evaluation of corrosion control options. However, EPA recognizes that 
the same timing issue as discussed above for plumbing replacement may 
be a concern. Specifically, systems would effectively have only 12 
months to install the POU devices at all required taps in order to be 
able to demonstrate two consecutive six-month monitoring periods where 
the action level was not exceeded, before the end of the 24-month 
deadline for installing corrosion control treatment. The Agency is 
requesting comment on whether there is enough existing flexibility 
under the current rule for small systems to optimize using POU devices 
or whether EPA should define POU devices as a corrosion control 
technique, or as an acceptable alternative to corrosion control for 
small systems, which would have the effect of giving systems 24 months 
rather than 12 months to install such treatment.
    EPA believes that there are a number of questions that would need 
to be resolved before listing POU as an alternative to corrosion 
control. What

[[Page 40841]]

would be the enforceable water quality parameters for this alternative 
to corrosion control? How would excursions from the optimal water 
quality parameters be measured? If these techniques are listed under 
Sec.  141.81(c)(1) as corrosion control techniques, would all systems 
need to evaluate them as part of the corrosion control study? For 
systems that fail to meet the action level, would the State still need 
to specify the minimum pH values, even though the system may not be 
adjusting pH?
3. Site Selection in Areas With Water Softeners and POU Treatment Units
    The previous section discussed the use of POU or POE devices on a 
system-wide basis to remove lead and/or copper. However, many homes 
have whole house (point-of-entry) water softeners or treatment units at 
the kitchen tap (point-of-use), even though the system is not 
installing and maintaining these units. Section 141.86(a)(1) states 
that sampling sites may not include faucets that have point-of-use or 
point-of-entry treatment devices designated to remove inorganic 
contaminants. EPA requests comment upon whether the LCR should be 
amended to allow lead and copper tap samples to be collected at taps 
that have POU/POE devices under certain conditions.
    Households may have reverse osmosis POU units that are capable of 
removing a number of contaminants, including lead and copper. These 
devices are typically installed with a separate tap at the kitchen 
sink. In systems where POU devices are not owned, controlled and 
maintained by the water systems, these sites could be included and 
still meet the requirements of Sec.  141.86(a)(1) because samples could 
be taken from the regular untreated tap at the kitchen or a sample 
could be taken from an untreated bathroom tap. Since POU devices have 
not been installed system-wide, samples should not be taken from a POU 
treated tap at these sites.
    Some areas of the country may find that the prevalence of POE water 
softeners restricts the ability of the water system to find homes where 
these units are not installed. This scenario is discussed in EPA's 
``Lead and Copper Rule Guidance Manual Volume 1: Monitoring'' that was 
published in September 1991. Figure 3-2 in that manual described 
preferred sampling pool categories for targeted sampling sites. 
Category F.2 was listed as an exception case for water systems that 
only have sites where water softeners have been installed. This 
situation has been observed in the mid-western United States. The 
guidance states that these systems should select the highest risk sites 
(newest lead solder or lead service lines) and monitor at those 
locations even though the water softener is present.
    The Agency is requesting public comment on whether the Lead and 
Copper Rule should be amended to allow sampling at locations with POU/
POE devices used to remove inorganic contaminants in exceptional cases 
(such as systems with high prevalence of water softeners), and if so, 
how high risk sites in these locations should be identified. EPA 
specifically requests comment on whether the Agency should codify the 
guidance provision discussed above.
4. Water Quality Parameter Monitoring
    The Agency requests comment on requiring systems to synchronize 
required water quality parameter sampling with lead and copper tap 
sampling. This would allow systems the ability to associate changes in 
water quality parameter levels with lead and copper levels and help 
systems monitor the effectiveness of their corrosion control program. 
EPA is aware of one State that has been instructing water systems with 
corrosion control treatment programs to collect water quality parameter 
samples during the same week the systems collect lead and copper tap 
samples. This State has observed that elevated lead levels have been 
frequently associated with low corrosion inhibitor or orthophosphate 
residuals in the distribution systems, and occasionally with low pH.
    Under the current rule, systems that have installed and operate 
corrosion control treatment per Section 141.82(c)(1) and 141.82(g) must 
monitor water quality parameters per Section 141.87(d). The number of 
water quality parameter tap samples depends on the population size 
served by the water system as detailed in 141.87(a)(2) and 
141.87(e)(1). The frequency of water quality parameter monitoring at 
taps in the distribution system ranges from twice every six months to 
twice every three years as described in 141.87(e). Systems required to 
monitor for water quality parameters must also collect one sample for 
each applicable water quality parameter at each entry point to the 
distribution system every two weeks.
    Water quality parameters are designated by the State primacy agency 
under 141.82(d). They typically include pH, alkalinity, and corrosion 
inhibitor residual. These parameters will vary based on the type of 
corrosion control a system installs and the State may designate 
additional parameters.
    EPA is requesting comment upon a modification that would not 
increase the number of samples a system would be required to take, but 
would synchronize sampling they are required to do under the current 
rule. Large systems would be required to take their required lead and 
copper samples at the same time they take their required water quality 
parameter samples. Small and medium systems would be required to take 
their water quality parameter samples at the same time as their lead 
and copper samples required by Section 141.81(c) during the compliance 
period following the monitoring period in which they exceeded the lead 
or copper action level and all subsequent monitoring periods in which 
they are scheduled to take both water quality parameter and lead and 
copper tap samples.
    Currently, if a small or medium system has an action level 
exceedance, they are required to take water quality parameter samples 
within the same six-month period according to Section 141.87(d). EPA is 
not requesting comment on whether to require these systems synchronize 
water quality monitoring with lead and copper monitoring under this 
circumstance. The Agency is only requesting comment on whether to 
require these small and medium systems to synchronize water quality 
monitoring and lead and copper monitoring during the compliance period 
following the circumstance described in Section 141.87(d) and all 
subsequent monitoring periods in which they are scheduled to take both 
water quality parameter and lead and copper tap samples.
    The Agency requests comment on including this potential 
modification in the final rule. EPA requests comment on what, if any, 
added burden it may present to water systems. The Agency also requests 
comment on the appropriate time frame for synchronizing water quality 
parameter monitoring with lead and copper monitoring. Should systems be 
required to take water quality parameter and lead and copper samples on 
the same day or within the same week within a monitoring period? What 
are the practical constraints associated with different time frames?

I. State Implementation

    States with approved primacy programs under 40 CFR part 142 subpart 
B must revise their programs to adopt any changes to the Lead and 
Copper Rule that are more stringent than their approved program. The 
primacy revision crosswalk table issued after the rule is final will 
list all the provisions

[[Page 40842]]

that States must adopt to retain primacy. Table III.1 summarizes the 
revisions being proposed today and identifies those that the Agency 
believes to be more stringent requirements.

------------------------------------------------------------------------

1. How Do These Regulatory Revisions Affect a State's Primacy Program?
    States must revise their programs to adopt any part of the proposal 
which is more stringent than the approved State program. Primacy 
revisions must be completed in accordance with 40 CFR 142.12 and 
142.16. States must submit their revised primacy application to the 
Administrator for approval. State requests for final approval must be 
submitted to the Administrator no later than two years after 
promulgation of a new standard unless the State requests and is granted 
an additional two-year extension.
    For revisions of State programs, Sec.  142.12 requires States to 
submit, among other things, ``[a]ny additional materials that are 
listed in Sec.  142.16 of this part for a specific EPA regulation, as 
appropriate (Sec.  142.12(c)(1)(ii)).'' For the proposed revisions to 
the lead and copper rule, EPA believes that requirements in Sec.  
142.12(c) will provide sufficient information for EPA review of the 
State revision. The side-by-side comparison of requirements required in 
Sec.  142.12(c)(1)(i) will consist of sections revised to adopt the 
changes required for the revised lead and copper rule and any other 
revisions requested by the State. Because the rule consists of changes 
to an already approved federal NPDWR in primacy States, EPA believes 
that the State's existing statutes and regulations will already have 
received extensive legal review. Under Sec.  142.12 (c)(3), EPA can 
request supplemental

[[Page 40843]]

information as necessary for a specific State submittal on a case-by-
case basis. Therefore, the Agency plans to waive the Attorney General's 
statement required in Sec.  142.12(c)(1)(iii), as allowed by Sec.  
141.12(c)(2). The Agency requests comment on whether the Attorney 
General's statement or any other documentation is necessary to approve 
revisions to State programs resulting from the rule.
2. What Does a State Have To Do to Apply?
    To maintain primacy for the Public Water System Supervision (PWSS) 
program and to be eligible for interim primacy enforcement authority 
for future regulations, States must adopt this proposal, when final. A 
State must submit a request for approval of program revisions that 
adopt the regulations and implement those regulations within two years 
of promulgation unless EPA approves an extension under Sec.  142.12(b). 
Interim primacy enforcement authority allows States to implement and 
enforce drinking water regulations once State regulations are effective 
and the State has submitted a complete and final primacy revision 
application. To obtain interim primacy, a State must have primacy with 
respect to each existing NPDWR. Under interim primacy enforcement 
authority, States are effectively considered to have primacy during the 
period that EPA is reviewing their primacy revision application.
3. How Are Tribes Affected?
    At this time the Navajo Nation has primacy to enforce the PWSS 
program. EPA Regions implement the rules for all the other Tribes under 
section 1451(a)(1) of SDWA.

J. Limitations to Public Comment on the Lead and Copper Rule

    EPA requests comment on the seven specific regulatory changes 
proposed today to revise the national primary drinking water 
regulations for lead and copper, as well as several related issues. 
Please note that the Agency is not proposing to revise the Lead Action 
Level or any major component of lead drinking water regulations. EPA is 
not reopening the entire Lead and Copper Rule, but rather is requesting 
comment on the rule changes and related issues specifically discussed 
in this proposal. In this rulemaking, the Agency will not consider 
comments that address other aspects of drinking water regulations for 
lead and copper.

K. Proposed Effective Dates

    Section 1412 (b)(10) of the Safe Drinking Water Act, requires that 
a proposed national primary drinking water regulation (and any 
amendments) take effect on the date that is three years after the date 
of promulgation, unless the Administrator determines that an earlier 
date is practicable. EPA is proposing that the revisions take effect 
three years after the promulgation of the final rule. Because several 
of the provisions in this rule would likely not require three years for 
implementation the Agency is considering whether to make some of these 
regulatory changes effective in less than three years after the date of 
publication of the final rule. Specifically, EPA requests comment on 
whether it would be practicable to implement the following changes and 
clarifications in this proposal to the Lead and Copper Rule within 60 
days of the date of publication of the final rule:
     Section III.A. Minimum Number Of Samples Required
     Section III.B. Definitions For Compliance And Monitoring 
Periods
     Section III.E. Requirement To Provide A Consumer Notice Of 
Lead Tap Water Monitoring Results To Consumers Who Occupy Homes Or 
Buildings That Are Tested For Lead
     Section III.F. Public Education Requirements
    The requirements described in Section III.A (minimum number of 
samples clarification) is merely a clarification of existing regulatory 
text and does not change the stringency of the rule. In Section III.B 
(compliance and monitoring period clarification) there are changes that 
clarify existing text of the rule as well. The requirements described 
in Section III.E (the consumer notice) and Section III.F (public 
education requirements) are some of the most important in this 
proposal. Those requirements are critical to the explanation of lead 
exposure from drinking water and communication of health effects to the 
public; and while they add requirements to the rule, systems are not 
likely to need three full years to implement the new requirements.
    The Agency requests comment on whether these regulatory revisions 
should have effective dates of sixty days after the publication of the 
final rule and if not, what timeframes are practicable. The Agency also 
requests comment on whether any of the other proposed revisions in this 
rule should have an effective date earlier than three years after 
publication of the final rule.

IV. Economic Analysis

    This section describes the estimates of annual costs for the seven 
proposed regulatory changes to utilities and States, including costs 
associated with administrative, monitoring, sampling, reporting, and 
notification activities. One-time, upfront costs of rule review and 
rule implementation are also described. There are two types of annual 
costs that may result from the rule changes--direct and indirect. 
Direct costs are from those activities that are specified by the rule 
change, such as costs for additional monitoring or distribution of 
consumer notices. A second type of cost may also result when systems 
and States use the information generated by directly-related rule 
activities to modify or enhance practices to reduce lead levels. These 
indirect costs, and related health risk reductions, are not quantified 
for the purposes of this analysis, but are described qualitatively in 
Section IV.K of this proposal and in Chapter 5 of the Economic Analysis 
(Economic and Supporting Analysis Short Term Regulatory Changes to the 
Lead and Copper Rule, U.S. EPA, 2006b). Table IV.1 summarizes the 
expected direct and indirect cost impacts for the seven regulatory 
changes.

A. Direct Costs

    The proposed revisions will result in direct costs to utilities and 
States from activities that are specified by the rule change, including 
administrative, monitoring, sampling, reporting, and notification 
activities. These costs will result in an increase in the overall costs 
associated with the LCR.
    The most recent cost estimates to utilities and States of the LCR 
can be found in the 2004 Information Collection Request for 
Disinfectants/Disinfection Byproducts, Chemical, and Radionuclides 
Rules (Information Collection Request for Disinfectants/ Disinfection 
Byproducts, Chemical, and Radionuclides Rules, U.S. EPA 2004b). The 
2004 ICR estimates administrative burden and costs associated with the 
LCR for systems and States. System costs are estimated for community 
water systems and non-transient non-community water systems to perform 
the following activities: monitoring for water quality parameters, tap 
sampling of lead levels for action level compliance, review of sample 
data, including the calculation of lead and copper 90th percentile 
levels, submission to the State of monitoring data and any other 
documents or reports, and recording and maintaining information. In 
addition, some systems must submit corrosion control studies, recommend 
and submit information regarding the completion of corrosion control 
treatment (CCT) or source water treatment installation, conduct public 
education, or conduct LSL monitoring, notification, and replacement. In 
the 2004 ICR, for the LCR requirements to CWSs and NTNCWSs, the average 
annual respondent cost was estimated to be $57.9 million and the burden 
was estimated to be 1.72 million hours for reporting (including lead 
service line replacement reporting), recordkeeping, and public 
education activities of the LCR. For States, the annual cost and burden 
incurred by primacy agencies for activities associated with the lead 
and copper regulation were estimated to be $6.8 million and 0.21 
million hours, respectively.

B. Overall Cost Methodologies and Assumptions

    As part of its comprehensive review of the Lead and Copper Rule, 
EPA collected and analyzed new data on various aspects of LCR 
implementation. When available and appropriate, this new information is 
used in estimating costs. If new information was not available about a 
cost item or assumption, previous analyses of LCR requirements were 
reviewed to determine if a suitable estimate was available. The 1991 
RIA, the 1996 RIA Addendum, and the various Information Collection 
Requests were all used as sources of information and assumptions.
    For the rule revisions that clarify rule language, if the costs 
associated with those activities were included in the original LCR cost 
estimates as presented in the 1991 RIA, those costs are not included in 
this analysis.

C. Direct Costs Associated With Regulatory Change III.A

    Regulatory change III.A clarifies EPA's intent that a minimum of 5 
samples must be taken when conducting compliance monitoring. If a 
system has fewer than the minimum number of sites required for 
sampling, then those systems will have to collect multiple samples on 
different days from the same site so that the total number of samples 
per monitoring period is 5.
    Although some systems may have to increase the number of samples 
taken in response to this clarification, there is very limited 
available data on the number of these systems and on the frequency with 
which they conduct lead and copper monitoring. Because of lack of data, 
EPA has not quantified the costs associated with Regulatory Change 
III.A. In EPA's best judgment, these costs would be minimal.

D. Direct Costs Associated With Regulatory Change III.B

    Regulatory Change III.B clarifies the meaning of ``monitoring 
period'' and ``compliance period,'' addressing in particular the date 
on which actions are triggered by an exceedance and the timing of 
samples under triennial monitoring. Based on the rule change, if a 
system exceeds the action level during a monitoring period, non-
compliance starts at the end of the monitoring period (for most systems 
on September 30). Under the previous language, it was not clear whether 
non-compliance began at the end of the calendar year (December 31) or 
at the end of the monitoring period (September 30).
    As a result of the rule change, activities triggered by an action 
level exceedance could begin three months earlier (i.e., at the end of 
September versus the end of December), but the duration of these 
activities would not likely be longer. The net result is a change in 
the timing of activities, with a difference of three months having a 
negligible, if any, impact on costs.
    Regulatory Change III.B also requires that systems on reduced 
monitoring, such as triennially or once every nine years, must take all 
compliance samples within the same calendar year during the June-
September monitoring period. Under previous LCR regulatory language, a 
system could collect compliance samples over multiple calendar years, 
as long as they were taken during the June-September time frame and 
during the three-year compliance period. Since this rule change does 
not alter the number of samples to be taken, but the timing of samples, 
the direct cost impact is expected to be minimal.

E. Direct Costs Associated With Regulatory Change III.C

1. Activities Resulting From Regulatory Change
    As a result of Regulatory Change III.C, utilities that have 90th 
percentile LCR monitoring samples that exceed the Lead Action Level, 
and are currently on reduced monitoring, will be required to resume 
standard monitoring schedules for monitoring lead at taps. In addition 
to monitoring activities, utilities will have to meet reporting 
requirements to the State/Primacy agency. State/Primacy agencies will 
be required to review utility monitoring reports.
2. Costs to Utilities
    The direct costs to utilities, summarized in Table IV.3, are 
estimated to be $2.4 million annually including $2.2 million in labor 
costs and $0.2 million in materials costs. Detailed estimates are 
provided in the Economic Analysis, Appendix C (Economic and Supporting 
Analysis Short Term Regulatory Changes to the Lead and Copper Rule, 
Appendix C, U.S. EPA 2006b).
    The systems that will incur costs under this regulatory change are 
those systems that exceed the Lead Action Level and that had been on 
reduced monitoring. The number of systems EPA estimates to exceed the 
Lead Action Level each year is 995 as shown in Table IV.2. This 
estimate is based upon 2003 Lead Action Level exceedances reported by 
States to EPA's Safe Drinking Water Information System for systems 
serving more than 3300 people. EPA used this data to estimate that 1.4 
percent of systems (including system serving fewer than 3300 people) 
will exceed the action level each year.

\1\ The Estimate for systems <3,300 is based upon data from systems >3,300.

    Source: For medium and large systems, January 2005 Summary of Lead 
Action Level, http://www.epa.gov/safewater/lcrmr/lead_data.html; for 
small systems, Summary, Lead Action Level exceedances for public water 
systems subject to the Lead and Copper Rule (For data through September 
13, 2004).
    The number of systems on reduced monitoring was estimated using 
state responses to the EPA survey on LCR implementation (State 
Implementation of the Lead and Copper Rule. U.S. EPA 2004d). States 
provided estimates of the percent of systems on reduced LCR monitoring. 
Based on this data, 91 percent of systems are on reduced lead and 
copper monitoring. This analysis assumes that systems that are likely 
to exceed the action level, and are on reduced monitoring, are likely 
to exceed at the same rate as all systems. Therefore, we assume that 91 
percent of the systems estimated as likely to exceed the action level 
are on reduced monitoring, and will therefore incur costs due to 
regulatory change III.C. This assumption is conservative, because 
systems that are likely to have exceedances are less likely to be on 
reduced monitoring in the first place.
    For the number of additional monitoring events, it is assumed that 
each utility will conduct 5 additional monitoring events in each three 
year period by switching from a reduced monitoring schedule (triennial) 
to standard tap monitoring (semi-annual). While reduced monitoring 
could refer to either monitoring once every year or once every three 
years, it is not possible to distinguish, from the state responses to 
the EPA survey, between systems monitoring once every year and systems 
monitoring once every three years. This analysis assumes that all 
systems on reduced monitoring are on a one sample every three years 
schedule, a conservative assumption that might slightly over-estimate 
costs. Likewise, the number of samples collected in each monitoring 
period will change when the utility switches from reduced monitoring to 
standard monitoring. Thus, a system that was on reduced monitoring, but 
is placed on regular monitoring after an Action Level exceedance under 
regulatory change III.C, will incur an additional 5 monitoring events 
over a 3 year period (6 monitoring events in three years under regular 
monitoring instead of 1 monitoring event in three years under reduced 
monitoring), with an increased number of samples collected in each 
event. The required number of samples varies by system size, with the 
smallest systems (serving less than or equal to 100 people) required to 
take 5 samples per monitoring event under both standard and reduced 
monitoring, and the largest systems (serving > 100,000 people) required 
to take 100 samples per monitoring event under standard monitoring, and 
50 samples per monitoring event under reduced monitoring.
3. Costs to States
    Regulatory Change III.C will require State/Primacy agencies to 
review utility monitoring reports as a result of resuming standard 
monitoring schedules. The direct costs to State/Primacy agencies is 
estimated to be $77,000 annually including $76,000 in labor costs and 
$1000 in materials costs, as summarized in Table IV.3. Detailed 
estimates are included in the Economic Analysis, Appendix C (Economic 
and Supporting Analysis Short Term Regulatory Changes to the Lead and 
Copper Rule, Appendix C, U.S. EPA, 2006b).

F. Direct Costs Associated With Regulatory Change III.D

1. Activities Resulting From Regulatory Change
    Regulatory Change III.D requires water systems to obtain prior 
approval by the State primacy agency to add a new source of water or 
change a treatment process prior to implementation. The current 
requirement is that systems notify States about changes in treatment or 
additions of new sources within 60 days of a change or addition. The 
proposed regulatory language allows as much time as needed for water 
systems and States to consult before a proposed change is approved.
    New system activities will include the preparation of the 
corrosiveness implications of treatment or source changes prior to the 
change and a letter to the state. New State/Primacy agency activities 
will include review of the system data on the corrosiveness

[[Page 40846]]

implications of a treatment or source change prior to a change, 
preparation of conclusions and coordination with utilities. The 
estimated costs to the affected systems and State/primacy agencies are 
summarized in Table IV.4.
2. Costs to Utilities
    The direct costs to utilities range from $474,000 to $733,000 
annually. These direct costs are strictly labor costs; materials costs 
are expected to be negligible. Estimates are summarized in Table IV.4. 
Detailed estimates are provided in Appendix D (Table 6.1) of the 
Economic Analysis (Economic and Supporting Analysis Short Term 
Regulatory Changes to the Lead and Copper Rule, Appendix D, U.S. EPA, 
2006b).
    In order to estimate the cost of this provision to utilities, 
information is needed on the number of systems that will change a 
treatment or add a source annually, as well as the number of systems 
that are located in States that already have a review and approval 
requirement. Systems located in these States will not incur additional 
costs under this provision.
    Many States already have a review and approval process for 
treatment or source changes. In 2004, as part of a review of the 
implementation of LCR requirements by States, EPA asked State programs 
a number of questions about how they implement different aspects of the 
LCR. Included were the following questions: ``How do systems notify the 
State of treatment changes? Does the State require that systems provide 
information about potential effects of treatment changes on corrosion 
control?''
    14 States indicated that they currently have a review and approval 
process for treatment changes. Another nine States have a process that 
requires a permit for treatment changes and an additional eight States 
review submissions of engineering plans for proposed changes. Although 
not a review and approval process focused specifically on the impact of 
a change on corrosion control, the permitting and plan review processes 
are comprehensive enough that they should include corrosion issues. For 
the purposes of this analysis, two estimates were used of the number of 
States that already have a review and approval process that would 
include information on corrosion issues: 14 States for a high end of 
the cost range and 31 States for a low end. Under the alternative in 
which only the 14 States with explicit review and approval are excluded 
from the count, 53,372 systems (of 72,213 CWSs and NTNCWSs) may incur 
costs for the regulatory change. Under the alternative in which States 
with permitting and plan review are also excluded from the count, 
27,615 systems may incur costs for this regulatory provision.
    An estimate is also needed of the number of systems that will 
change a treatment or add a source annually, in order to estimate the 
cost of this provision to utilities. Treatment changes over the next 
several years are likely, as systems will be faced with new regulatory 
requirements, including changes to comply with the already promulgated 
Arsenic Rule and the upcoming Long Term 2 Surface Water Treatment Rule 
and the Stage 2 Disinfectants/Disinfection Byproducts Rule. EPA 
estimated the number of systems that would undertake treatment changes 
for the following new regulatory requirements:
     Arsenic--4,100 systems (Data source: Arsenic in Drinking 
Water EA, pp. 6-25, 6-27;
     LT2--2,968 systems (Data source: June 2003 draft EA, pp. 
6-23, 4-23);
     Stage 2 D/DBP--1,824 systems (Data source: July 2003 draft 
EA, pp. 6-35, 6-30).
    Together, these regulatory requirements are estimated to cause 
8,892 systems to institute a treatment change, although not all of 
these treatment changes will affect corrosion control. Also the 
compliance periods for these regulations varies. For example, the Stage 
2 and LT2 treatment changes are projected to take place within a 6 year 
compliance period for large systems (with the possibility of 2-year 
extension) and 8 years for small systems (with the possibility of 2-
year extension). To account for these expected treatment changes, and 
to account for treatment changes unrelated to the arsenic, LT2, and 
Stage 2 rules, EPA assumed (based on the projected rule-related 
treatment changes and expert judgment) that approximately 20% of the 
systems affected by the LCR will institute a treatment change in the 
next ten years. It is assumed that these changes occur uniformly over 
that 10-year period, so that approximately one-tenth of these systems 
(or 2 percent of the total) institute a treatment change each year.
    Using the 2 percent estimate, 1,067 (53,372 x .02) systems each 
year would report a treatment change or source addition and incur costs 
in that year in States currently not covered by an explicit review and 
approval program. The estimate for the number of systems is 552 if 
States with a permitting or plan approval process are also excluded.
    EPA anticipates that systems will incur additional costs under this 
rule change as systems and States more carefully review and consider 
possible corrosion impacts of treatment changes or source additions. 
The activities and burden associated with the review and approval 
process are expected to vary based on the size and complexity of a 
system, and the nature of the change or source addition. In the absence 
of information on the current prevalence of these activities, EPA has 
used the best professional judgment to estimate the range of potential 
activities and associated costs resulting from the review and approval 
process. All systems, regardless of size or complexity, are assumed to 
undertake additional activities related to data collection and 
evaluation, preparation of a submittal to the State, and coordination 
with the State. For small systems or systems making relatively simple 
changes, considering the corrosion impacts of the change may be a 
rather basic process of reviewing water quality data and previous lead 
monitoring results. For these systems, additional effort will be 
incurred by system staff in coordination with State personnel to 
assemble water quality parameter and lead data and evaluate the 
potential impacts. EPA estimates the burden for this additional effort 
at 7.5 hours per system, at an average cost of $201 per system. For 
larger or more complex systems making major treatment changes, 
activities would be more extensive, including conducting engineering 
studies to evaluate impacts on corrosion control. Based on best 
professional judgment, EPA estimates that between 10 percent and 20 
percent of medium and large systems may need to conduct additional 
engineering studies on corrosion impacts at a cost of $20,000. To some 
extent, systems may already evaluate the impacts of treatment or source 
changes on corrosion. EPA has considered these current activities in 
estimating the portion of systems that would require an engineering 
study.
3. Costs to States
    The direct costs to State/Primacy agencies are estimated to range 
from $153,000 to $328,000 annually. These direct costs are strictly 
labor costs; materials costs are expected to be negligible. Estimates 
are summarized in Table IV.4. Activities that States will undertake 
include review of system data, preparation of conclusions and letter to 
systems, and coordination with utilities. Because the level of effort 
associated with these activities is expected to vary based on the 
complexity of the change and the type of submittal (amount and type of

[[Page 40847]]

information), EPA included a range on State review from 4 to 8 hours.
    Those States incurring additional costs due to regulatory change 
III.D are those that do not already have a review and approval process 
which considers the corrosion control implications of treatment 
changes. All States currently review treatment or source changes within 
60 days after the change. However, some States are already reviewing 
and issuing approval before such changes are made. Based on the State 
program responses to the EPA questions on the implementation of LCR 
requirements (on existing review and approval processes), the analysis 
assumes either that 14 States have existing explicit review and 
approval processes or that 31 States have existing review and approval 
processes (if permit and plan review processes are also counted). The 
remaining States under each alternative will incur costs under this 
regulatory change as they review and approve changes before they are 
made, rather than simple review after the change has been made.
    For the States that will incur new costs, new State/Primacy agency 
activities will include review of the system data on the corrosiveness 
implications of a treatment or source change prior to a change, 
preparation of conclusions and coordination with utilities.

G. Direct Costs Associated With Regulatory Change III.E

1. Activities Resulting From Regulatory Change
    Regulatory Change III.E will require CWSs to provide written 
notification to each owner/occupant of the lead level found in the tap 
sample collected for LCR compliance monitoring. Compliance for NTNCWSs 
will be determined by their circumstances, and may consist of posting a 
notice on community bulletin boards or web sites. While State primacy 
agencies may review sample customer letters/notices from each utility 
for each monitoring period, such a review is not required by the 
regulatory change and thus is not considered a direct cost of the 
regulatory change. Supporting calculations and information regarding 
costs to utilities and States associated with this regulatory change 
are included in the Economic Analyses, Appendix E (Economic and 
Supporting Analysis Short Term Regulatory Changes to the Lead and 
Copper Rule, Appendix E, U.S. EPA, 2006b).
2. Costs to Utilities
    The direct costs to utilities for compliance with Regulatory Change 
III.E are summarized in Exhibit 4 and estimated to be $1,028,000 
annually including $894,000 in labor costs and $134,000 in materials 
costs for envelopes and postage. This is based on 310,510 notices being 
provided to customers each year, with estimated associated labor. 
Detailed estimates are provided in the Economic Analysis, Appendix E-2 
(Economic and Supporting Analysis Short Term Regulatory Changes to the 
Lead and Copper Rule, Appendix E, U.S. EPA, 2006b).
    In order to estimate the additional costs associated with 
regulatory change III.E, an estimate is needed of the number of systems 
that already notify customers of tap monitoring results. Based on 
feedback from participants in workshops and interactions with States, 
some systems already notify customers of monitoring results. These 
systems would not incur costs under the proposed regulatory change. 
This analysis uses information from the State survey (State 
Implementation of the Lead and Copper Rule. U.S. EPA, 2004) to develop 
an estimate of the number of systems that currently notify customers of 
tap sampling results. Of 72,213 CWS and NTNCWSs (per 2004 SDWIS/Fed 
data) subject to the LCR, approximately 11 percent of these systems are 
estimated to already notify owner/occupants of tap sample results. 
Therefore, this regulatory change will apply to the remaining 89 
percent of systems.
3. Costs to States
    No new costs to States are assumed. States are not required to 
review the notification letter or notice.

H. Direct Costs Associated With Regulatory Change III.F

    Regulatory Change III.F changes the public education requirements 
of the Lead and Copper Rule (LCR) in Sec.  141.85. Water systems would 
still be required to deliver public education materials after a Lead 
Action Level exceedance, but the text of the message to be provided to 
consumers, how the materials are delivered to consumers, and the 
timeframe in which materials must be delivered would change. The 
changes to the delivery requirements include additions to the list of 
organizations systems must partner with to disseminate the message to 
at-risk populations as well as changes to the media used to ensure 
water systems reach consumers when there is an action level exceedance.
    In addition to the changes to Sec.  141.85 of the LCR, revisions 
will be made to Sec.  141.154(d) of the CCR rule (40 CFR 141, Subpart 
O) which requires community water systems to send an annual report to 
billed customers containing information relevant to the quality of the 
drinking water provided by the system. EPA is proposing to change the 
CCR rule to require all community water systems that detect lead to 
include information about the risks of lead in drinking water on a 
regular basis.
1. Activities Resulting From Regulatory Change
    (a) Changes to the mandatory text of the written materials.
    (a)(1) Customer Notification: Deliver brochures to all bill-paying 
customers within 60 days.
    The brochure will include a section on ``What happened? What is 
being done?'' to be developed by each water system. Mandatory language 
will address essential topics such as the opening statement and health 
effects language. The mandatory language will be shorter and easier to 
understand than the language that is currently used. EPA will develop 
suggested language.
    (b) Changes to better reach at-risk populations.
    (b)(1) Brochures will be delivered to additional organizations, 
with a cover letter.
    The organizations to be added to the list of required recipients of 
the brochures will increase the likelihood that the most vulnerable 
populations or their caregivers will receive the information they need 
to reduce their exposure to lead in drinking water. These organizations 
will include licensed childcare centers, preschools and Obstetricians-
Gynecologists and Midwives. Also, local public health agencies will be 
contacted by phone.
    (b)(2) Systems will perform additional activities.
    Systems serving more than 3,300 will be required to implement three 
or more activities from a list of possible activities. Systems serving 
fewer than 3,300 will be required to implement one activity from the 
list. A list of nine possible activities follows (including a general 
``other methods'' because the primacy agency may also approve other 
methods). An estimate of the annual cost of each identified activity is 
given in Table IV.6.
    (i) Public Service Announcement: Production of a radio PSA includes 
developing a script for the spot and then producing an audio of the 
spot.
    (ii) Paid advertisement.
    (iii) Information display in public areas: Posting a notice at a 
local grocery store or laundromat.
    (iv) Internet: Email contact with all customers.
    (v) Public Meetings: For systems serving fewer than 3,300, system 
representatives would bring up the issue for discussion at an existing 
town meeting. For systems serving over 3,300, a separate public meeting 
would be held. This activity includes making logistical arrangements, 
preparing a 30-45 minute presentation, attending the meeting, and doing 
follow-up activities such as meeting notes.
    (vi) Delivery to every household: Delivery to every postal address, 
either through mail or distribution of flyers.
    (vii) Targeted individual contact with customers: Especially 
vulnerable customers, such as pregnant women and children, would be 
individually contacted.
    (viii) Materials to be provided directly to multi-family homes and 
institutions.
    (ix) Other methods approved by the primacy agency.

    Details of how these unit costs were calculated are provided in 
Appendices H-6 through H-20 of the Economic Analysis for the rule.
    (b)(3) Review activities for States.
    States will review the language in the utility's notice to 
consumers to make sure the utility is including the required 
information. States will also consult with each system with an action 
level exceedance. States will no longer be required to approve a waiver 
for notifications for each system that exceeds the Lead Action Level 
that serves a population of 501-3,300.
    (c) Changes to help systems maintain communication with consumers 
throughout the exceedance.
    (c)(1) Every water bill will contain a message about lead while a 
system is exceeding the action level.
    (c)(2) Post brochure on Web site if system serves >100,000 people.
    (c)(3) Public service announcements and press releases.
    The requirement to send public service announcements (PSAs) to TV 
stations and radio stations every six months while a system has an Lead 
Action Level exceedance will be cut to once every year. The PSA must be 
sent to five TV stations and five radio stations. A press release will 
still have to be submitted to newspapers, TV stations and radio 
stations.
    (d) Changes to the required timing.
    No cost impact.

[[Page 40849]]

    (e) Changes to Consumer Confidence Report.
    (e)(1) Inclusion of an informational statement on CCR for all 
systems.
    Systems that detect lead in their drinking water will have to 
include an informational statement about lead in their CCR. Currently, 
only those systems with more than five percent of their sites above the 
Lead Action Level must include an informational statement in their CCR.
2. Costs to Utilities
    The direct costs to utilities as a result of Regulatory Change 
III.F are estimated to be $780,500. The annual system labor cost is 
estimated to be $759,500, with the annual system materials cost 
$21,000. Estimates of costs associated with each activity are given in 
Table IV.7. Detailed estimates of costs to utilities are provided in 
the Economic Analysis, Appendix F (Economic and Supporting Analysis 
Short Term Regulatory Changes to the Lead and Copper Rule, Appendix F, 
U.S. EPA, 2006b). The costs for the CCR component may be overstated 
because EPA does not have specific data to determine the percentage of 
systems that will not detect lead. Thus, we have assumed that all 
systems will detect lead in their water, which may lead to an 
overstatement of the cost estimates shown in Table IV.7. In addition, 
the requirement to provide information about lead in the CCR would be 
new only for systems that currently detect lead below the action level 
in 95% or more of their sites, since systems in which the 95th 
percentile result is above the action level are already required to 
provide such information. However, EPA does not have data on such 
systems. Rather, EPA has data on the (smaller) number of systems that 
currently detect lead below the action level in 90% of their sites, and 
has subtracted this value from the universe of systems to estimate the 
number of systems that would incur new costs under this requirement. 
Thus, there are two factors contributing to a possible overestimate in 
the national cost for the CCR statement. The first factor is that 
assuming all systems will detect lead overestimates the number of 
systems that will actually detect lead, because some systems do not 
detect any lead. The second factor is that underestimating the current 
baseline of systems that currently detect lead at the 95th percentile 
level, by using data on systems that detect lead at the 90th percentile 
level (a smaller number of systems), overestimates the remaining number 
of systems that do not currently report lead information in their CCR. 
EPA's estimate assumes that 52,257 additional systems would have to 
provide information about lead in their CCR each year, with additional 
associated labor of 0.25 hours per system per year.

I. Direct Costs Associated with Regulatory Change III.G

1. Activities Resulting From Regulatory Cchange
    Under this proposed change, utilities that have 90th percentile LCR 
samples that exceed the Lead Action Level will need to identify all 
lead service lines (LSL) that had previously been determined to be 
replaced via sampling. If a LSL was previously ``tested out'' or 
determined to be replaced by sampling, the sample previously collected 
from the LSL had a lead level less than the Lead Action Level. These 
utilities would be affected by Regulatory Change III.G if they exceed 
the action level again and renew a LSL replacement program. These 
utilities must put these ``tested out'' LSLs back into their inventory 
of lead service lines that could be considered for replacement. To 
estimate the impact of this change, we assume these formerly ``tested 
out'' LSLs will be retested, and that some of them will exceed the Lead 
Action Level. The primary activities as a result of this regulatory 
change include collecting and analyzing samples from these LSLs. 
Replacement of lines that were previously tested out may also occur as 
a result of this change.
2. Costs to Utilities
    The direct costs to utilities as a result of Regulatory Change 
III.G are estimated to be $97,000 annually, which includes $87,000 in 
labor costs and $10,000 in materials costs. Detailed estimates of costs 
to utilities are provided in the Economic Analysis, Appendix F 
(Economic and Supporting Analysis Short Term Regulatory Changes to the 
Lead and Copper Rule, Appendix F, U.S. EPA, 2006b). Estimating the 
costs to utilities requires an estimate of the number of systems who 
have been involved in a lead service line replacement program, the 
number of systems likely to discontinue such a program due to low 
tested lead levels, and the fraction of those systems likely to 
subsequently exceed the action level and restart their lead service 
line replacement program.
    In the responses to the 50 state survey on lead implementation 
(State Implementation of the Lead and Copper Rule U.S. EPA, 2004), 11 
States responded that at least one system in their state has been 
involved in a lead service line replacement program. Six States 
provided sufficient information to derive a number of systems within 
that State required to perform lead service line replacement--a total 
of 28 systems. Based on an average of five systems per State for the 
six States that provided data, we assume that the remaining five States 
have five systems, plus one system for DC (which did not respond to the 
survey) for a total of 54 systems that have been required to perform 
lead service line replacement.
    Because there is not sufficient information to determine how many 
of 54 systems suspended their lead replacement programs, and later 
restarted the programs due to an exceedance, we assumed the worst case 
scenario that all of these systems suspended their lead replacement 
programs and that the rate of subsequent exceedance was the same as for 
the universe of systems subject to the LCR, as shown in Table IV.2. 
Thus, we assume that 1.4 percent of the 54 systems or 1 system will 
exceed the Action Level and be triggered back into lead service line 
replacement each year.
    EPA does not have information on the number of systems using the 
test out provisions rather than physically replacing lines, so this 
approach is conservative because it assumes that all systems in a lead 
service line replacement program are using the test out provisions. 
Systems removing lead service lines are not impacted by this change. 
While the rate at which systems are triggered back into lead service 
line replacement might be higher than the initial rate, it is offset by 
the conservative assumptions regarding systems using the test out 
provisions and the universe of systems that would stop their lead 
service line replacement program and later resume it because of this 
change.
    Replacement of lines that were previously tested out may also occur 
as a result of this change. EPA cannot quantify the costs associated 
with this change for a number of reasons. As noted above, EPA does not 
have information on the number of systems and the number of lines that 
have been previously tested out and could be impacted by this change. 
This difficulty is further compounded by the fact that some lines may 
have been replaced as part of the ongoing utility replacement programs. 
In the 1991 final regulatory impact analysis, EPA cited an AWWA survey 
that produced an estimate of 1 percent of lead service lines being 
replaced per year as part of ongoing utility replacement programs. 
After promulgation of the rule, many systems modified their ongoing 
utility replacement programs to replace lead lines at a higher rate.
    Where lines would have to be replaced, the unit cost of replacement 
is measured in $ per foot of line being replaced. The 1991 final 
regulatory impact analysis provided a range of $26 to $51 per foot, 
depending upon system size, as the unit cost for lead service line 
replacement. Using the Engineering News Record Construction Cost Index, 
updated estimates would range from $41 per foot for small systems to 
$80 per foot for large systems. The length of the lead service line 
owned by systems will also vary, which will affect costs.
    The derivation of the number of lead service lines per system and 
the number of lines to be retested are based on several assumptions. 
Since EPA does not know the number of years that the system was on the 
lead service line replacement program before meeting the AL, a 
conservative assumption was made that all lines were either tested or 
physically replaced. EPA estimated that the one system impacted by this 
change is a large system with 21,467 lead service lines. The percent of 
lead service lines tested out rather than replaced is estimated at 76 
percent based on one year of data from DC WASA. It is likely that the 
estimates of the proportion of lines that are tested out rather than 
replaced is high because the 76 percent test out was during an initial 
year of replacement when a system is more likely to be able to test out 
lines rather than replace them. The time required to physically replace 
lines also leads to a higher percentage of test outs in the first year 
at DC WASA. We do not know the remaining years in the lead service line

[[Page 40851]]

replacement program, therefore, we assumed that 76 percent of lead 
service lines will need to be retested over a 15 year period. The 
resulting number of lead service lines that are assumed to be retested 
each year is 1,088.
3. Costs to States
    No direct costs are expected for State/Primacy agencies as a result 
of Regulatory Change III.G. The State/Primacy Agencies will review 
utility Lead Service Line replacement program annual reports but these 
costs were captured previously in the Final Regulatory Impact Analysis 
of National Primary Drinking Water Regulations for Lead and Copper, 
April 1991 (Final Regulatory Impact Analysis of National Primary 
Drinking Water Regulations for Lead and Copper, U.S. EPA, 1991b).

K. Total Upfront Costs to Review and Implement Regulatory Changes

1. Activities Resulting From Regulatory Change
    Systems and State/Primacy Agencies will incur one-time upfront 
costs associated with reviewing and implementing the overall LCR 
regulatory changes. For systems, activities include reviewing the rule 
changes and training staff. For States/Primacy Agencies, activities 
include regulation adoption, program development, and miscellaneous 
training.
2. Total Costs to Utilities
    Direct costs to utilities are estimated to be $8.1 million as 
summarized in Table IV.8. Detailed estimates of costs to utilities are 
provided in the Economic Analysis Appendix G (Economic and Supporting 
Analysis Short-Term Regulatory Changes to the Lead and Copper Rule, 
Appendix G, U.S. EPA, 2006b). Direct costs to utilities are based 
solely on labor; no materials costs are expected for these one-time 
upfront costs.
3. Total Costs to States
    Direct costs to the States are estimated to be $0.7 million as 
summarized in Table IV.10 and detailed in Appendix G of the Economic 
Analysis (Economic and Supporting Analysis Short-Term Regulatory 
Changes to the Lead and Copper Rule, U.S. EPA, 2005b, Appendix A). 
Similar to one-time costs for utilities, these direct costs are based 
solely on upfront labor costs. Fifty-seven state primacy agencies will 
review and implement these LCR revisions.

L. Indirect Costs

    Previous sections focused on the direct costs of the proposed 
rulemaking, costs resulting from activities specified by the rule 
change, such as costs for additional monitoring or distribution of 
consumer notices. A second type of cost, an indirect cost, may also 
result when systems and States use the information generated by the 
rule-required activities to modify or enhance practices to reduce lead 
levels. Indirect costs may also result if systems or States decide to 
undertake additional

[[Page 40852]]

information-gathering activities not required by the rule.
    The proposed revisions will require some systems to generate new 
information which, in some cases, may be provided to States and 
customers. The information that is generated may suggest lead and 
copper risks that would not otherwise have been discovered (or such 
risks might be discovered sooner than otherwise). Upon obtaining this 
information, a system itself, the State, or some of the system's 
customers may take actions to address these risks, incurring the costs 
of those actions. For example, a system may redesign a planned 
treatment change following State review of the planned change. Or a 
system may replace a lead service line that was previously ``tested 
out.'' System customers, upon receiving notification of the lead 
content of their tap samples, may take some action, and in the process, 
incur a cost.
    It is both difficult to project what the content will be of the 
information generated pursuant to the regulation, and difficult to 
predict how systems and individuals might act in response to the new 
information generated as a result of these regulatory changes. Because 
of the uncertainty in tracing the linkages from the regulation to new 
information to exposure prevention measures, EPA is unable to quantify 
the indirect costs that might ensue from these regulatory changes.
    It is also possible that some additional information-gathering 
activities may result from the rule. For example, a system may decide 
to undertake a new study of the corrosion implications of a rule 
change. Or a state may decide to review sample system customer letters 
of notification to owner/occupants about the lead levels found in their 
collected tap samples. These activities would also result in indirect 
costs associated with the rule.

M. Benefits

    The intent of this proposed rulemaking is to improve implementation 
of the lead and copper regulations by clarifying monitoring 
requirements, improving customer awareness, and modifying the lead 
service line test out procedure. The proposed revisions do not affect 
the action levels, corrosion control requirements, line replacement 
requirements, or other provisions in the existing rule that directly 
determine the degree to which the rule reduces risks from lead and 
copper.
    However, the increase in administrative activities that will result 
from the revisions will result in the generation of new information 
(e.g., more monitoring data, some of which may show exceedances), and 
may prompt some systems or individuals to respond to this new 
information by taking measures to abate lead and copper exposures and 
thus reduce the associated risk. Also, the requirement that treatment 
changes be approved by the primacy agency prior to implementation will 
provide an additional opportunity to identify possible adverse impacts 
due to treatment changes, which may lower the risk to consumers. 
Because the precise impact of these proposed revisions on the behavior 
of individuals and systems is not known, EPA has not quantified the 
changes in health benefits associated with these proposed revisions. 
EPA does expect that overall benefits from the LCR will increase, as a 
result of the indirect effect of the revisions on the actions of 
individual consumers and systems.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    Under Executive Order 12866, [58 Federal Register 51735 (October 4, 
1993)] the Agency must determine whether the regulatory action is 
``significant'' and therefore subject to OMB review and the 
requirements of the Executive Order. The Order defines ``significant 
regulatory action'' as one that is likely to result in a rule that may: 
(1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or Tribal governments or 
communities; (2) create a serious inconsistency or otherwise interfere 
with an action taken or planned by another agency; (3) materially alter 
the budgetary impact of entitlements, grants, user fees, or loan 
programs or the rights and obligations of recipients thereof; or (4) 
raise novel legal or policy issues arising out of legal mandates, the 
President's priorities, or the principles set forth in the Executive 
Order.
    Pursuant to the terms of Executive Order 12866, OMB has notified 
EPA that it considers this a ``significant regulatory action'' within 
the meaning of the Executive Order. EPA has submitted this action to 
OMB for review. Changes made in response to OMB suggestions or 
recommendations are documented in the public record.

B. Paperwork Reduction Act

    The information collection requirements in this proposed rule have 
been submitted for approval to the Office of Management and Budget 
(OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The 
Information Collection Request (ICR) document prepared by EPA has been 
assigned EPA ICR number XXXX.XX.
1. Need for the Information Collection
    EPA requires current information on lead and copper contamination 
to be provided to consumers and States. Recent highly publicized 
incidences of elevated drinking water lead levels prompted EPA to 
review and evaluate the implementation and effectiveness of the LCR on 
a national basis. As a result of this multi-part review, EPA identified 
seven targeted rule changes that clarify the intent of the LCR and 
enhance protection of public health through additional information 
gathering and public education. Consumers and States will use the 
information collected as a result of the short-term revisions to the 
LCR to determine the appropriate action they should undertake. The rule 
revisions described in Section III of this proposal are intended to 
improve the implementation of the LCR, and do not alter the original 
maximum contaminant level goals or the fundamental approach to 
controlling lead and copper in drinking water.
    Section 1401(1)(D) of the SDWA requires that regulations contain 
``criteria and procedures to assure a supply of drinking water which 
dependably complies with such maximum contaminant levels, including 
accepted methods for quality control and testing procedures to insure 
compliance with such levels and to insure proper operation and 
maintenance of the system * * * .'' Furthermore, Section 1445(a)(1) of 
the SDWA requires that every person who is a supplier of water ``shall 
establish and maintain such records, make such reports, conduct such 
monitoring, and provide such information as the Administrator may 
reasonably require by regulation to assist the Administrator in 
establishing regulations * * *, in determining whether such person has 
acted or is acting in compliance. * * *'' In addition, Section 
1413(a)(3) of the SDWA requires States to ``keep such records and make 
such reports * * * as the Administrator may require by regulation.''
    Section 1412(b) of the SDWA, as amended in 1996, requires the 
Agency to publish maximum contaminant level goals and promulgate NPDWRs 
for

[[Page 40853]]

contaminants that may have an adverse effect on the health of persons, 
are known to or anticipated to occur in PWSs, and, in the opinion of 
the Administrator, present an opportunity for health risk reduction. 
The NPDWRs specify maximum contaminant levels or treatment techniques 
for drinking water contaminants (42 U.S.C. 300g-1). Section 1412(b)(9) 
requires that EPA no less than every 6 years review, and if 
appropriate, revise existing drinking water standards. Promulgation of 
the LCR implements these statutory requirements.
2. Burden Estimate
    The universe of respondents for this ICR is comprised of the 52,838 
CWSs and 19,375 NTNCWSs, for a total of 72,213 systems, and 57 State 
primacy agencies. Table V.1 presents a summary of total burden and 
costs for the ICR period of 2006-2008.
    The annual system burden is estimated at 107,924 hours in 2006, 
107,924 hours in 2007, and 107,924 hours in 2008. The annual system 
costs are projected at $2.7 million in 2006, $2.7 million in 2007, and 
$2.7 million in 2008.
    The annual State burden is estimated at 5,928 hours in 2006, 5,928 
hours in 2007, and 5,928 hours in 2008. The annual State costs are 
projected at $243,226 in 2006, $243,226 in 2007, and $243,226 in 2008. 
These annual costs reflect the costs to systems and States for the 
first three years after rule promulgation and consist of the one-time 
direct costs for rule review and implementation. Upon the effective 
date of the rule, three years after rule promulgation, EPA estimates 
annual costs to systems for all proposed regulatory revisions ranging 
from $4.8 to $5.1 million and annual costs to States for all proposed 
regulatory revisions ranging from $281,000 to $456,000. A detailed 
discussion of these costs is presented in Section IV of this notice.
3. Bottom Line Burden Hours and Costs
    The total burden and costs for the three year compliance period of 
2006 to 2008 is summarized in Table V.1. The total burden and costs for 
each regulatory change is explained in the ICR document for this 
proposed action.

    Burden and costs are the same in all three years as it is assumed 
that the one-time costs to prepare for rule implementation will be 
spread over the three year period prior to compliance with the 
regulatory changes.
4. Burden Statement
    For the ICR period of 2006 through 2008 associated with the short-
term revisions to the LCR, the average burden for systems to implement 
the proposed requirements of the short-term LCR revisions is estimated 
to be 1.49 hours per system per year. The average annual cost to 
systems is expected to be $37.28 per system per year. System burden 
includes time to read and understand the rule requirements and 
communicate those requirements to system personnel and management. The 
average burden for State agencies is estimated to be 104 hours per 
State per year. This burden includes the time to inform systems of the 
requirements, and perform primacy related activities. The estimated 
annual State cost is estimated to be $4,267 per State per year.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, or disclose or 
provide information to or for a Federal agency. This includes the time 
needed to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.
    An agency may not conduct or sponsor, and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations in 40 CFR are listed in 40 CFR part 9. To comment on the 
Agency's need for this information, the accuracy of the

[[Page 40854]]

provided burden estimates, and any suggested methods for minimizing 
respondent burden, including the use of automated collection 
techniques, EPA has established a public docket for this rule, which 
includes this ICR, under Docket ID number 2005-0034. Submit any 
comments related to the ICR for this proposed rule to EPA and OMB. See 
ADDRESSES section at the beginning of this proposal for where to submit 
comments to EPA. Send comments to OMB at the Office of Information and 
Regulatory Affairs, Office of Management and Budget, 725 17th Street, 
NW., Washington, DC 20503, Attention: Desk Office for EPA. Since OMB is 
required to make a decision concerning the ICR between 30 and 60 days 
after July 18, 2006, a comment to OMB is best assured of having its 
full effect if OMB receives it by August 17, 2006. The final rule will 
respond to any OMB or public comments on the information collection 
requirements contained in this proposal.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to prepare a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements under the Administrative 
Procedure Act or any other statute unless the agency certifies that the 
rule will not have a significant economic impact on a substantial 
number of small entities. Small entities include small businesses, 
small organizations, and small governmental jurisdictions.
    The RFA provides default definitions for each type of small entity. 
Small entities are defined as: (1) A small business as defined by the 
Small Business Administration's (SBA) regulations at 13 CFR 121.201; 
(2) a small governmental jurisdiction that is a government of a city, 
county, town, school district or special district with a population of 
less than 50,000; and (3) a small organization that is any ``not-for-
profit enterprise which is independently owned and operated and is not 
dominant in its field.'' However, the RFA also authorizes an agency to 
use alternative definitions for each category of small entity, ``which 
are appropriate to the activities of the agency'' after proposing the 
alternative definition(s) in the Federal Register and taking comment. 5 
U.S.C. 601(3)-(5). In addition, to establish an alternative small 
business definition, agencies must consult with SBA's Chief Counsel for 
Advocacy.
    For purposes of assessing the impacts of this proposal on small 
entities, EPA considered small entities to be public water systems 
serving 10,000 or fewer persons. As required by the RFA, EPA proposed 
using this alternative definition in the Federal Register (63 FR 7620, 
February 13, 1998), requested public comment, consulted with the Small 
Business Administration (SBA), and finalized the alternative definition 
in the Consumer Confidence Reports regulation (63 FR 44511, August 19, 
1998). As stated in that Final Rule, the alternative definition is 
applied to this regulation as well.
    After considering the economic impacts of this proposed rule on 
small entities, EPA certifies that this action will not have a 
significant economic impact on a substantial number of small entities. 
The small entities directly regulated by this proposed rule are small 
public water systems serving 10,000 or fewer people on an annual basis. 
We have determined that 68,286 small systems will experience an impact 
from .004 percent to .13 percent of their revenues (see section 
V.C.10). Table V.4 provides a summary of these small systems, by size 
category and system type.

    However, not all of these small entities will be affected and incur 
direct costs for all of the proposed rule changes. In many cases, only 
a relatively small subset of these systems will have to change 
practices to comply with the rule changes. Table V.5 provides an 
estimate of the number of small systems that will incur direct costs 
for each of the proposed rule changes.

1. Activities and Costs Associated With Rule Changes for Small Systems
    EPA has estimated the burden and costs associated with the proposed 
rule changes as described in the Economic Analysis support document. 
The basis for many of these input values and assumptions are described 
in detail in the Economic Analysis, Section 4. The following summarizes 
the costs estimated for small systems.

[[Page 40855]]

2. One-Time Activities
    All small systems subject to the Lead and Copper Rule will be 
expected to incur some costs to read the proposed rule changes and 
communicate requirements as necessary. The level of effort associated 
with these activities could range from 4-8 hours for all small systems. 
The average cost per system for these activities is estimated at $105, 
for a total cost of $7,193,000 for all 68,286 small systems. This 
assumes an hourly fully loaded labor cost for small system employees 
ranging from $22.70 to $26.83 (see Appendix B of the Economic Analysis 
for derivation).
3. Activities for Regulatory Change III.C
    Under Regulatory Change III.C, all systems that exceed the Lead 
Action Level are triggered into regularly scheduled lead tap 
monitoring. Additional costs are associated with taking lead samples 
more frequently and reporting the results to States. EPA estimates that 
854 small systems exceed the Action Level each year. Changing from 
reduced tap monitoring to a regular tap monitoring schedule would 
result in an average cost increase of $2,092 per year per system. Total 
costs for all small systems are estimated at $1,786,000 per year.
4. Activities for Regulatory Change III.D
    Small systems that are changing treatment or adding a source would 
incur additional costs under Regulatory Change III.D to prepare data in 
support of proposed treatment changes or source addition, submit the 
data to the State for review, and coordinate with the State during the 
review. These activities are estimated to take an additional 7.5 hours 
per system for each treatment change or source addition. The cost for 
each small system that is changing treatment or adding a source is 
estimated at $201. The total cost for small systems is estimated at 
$203,000 per year.
5. Activities for Regulatory Change III.E
    Most small systems are expected to incur additional costs under 
Regulatory Change III.E when they are required to notify consumers of 
tap monitoring results. The activities associated with notifying 
customers vary based on the type and size of the system. The average 
cost for small systems to notify customers is estimated at 
approximately $14 annually. This estimate assumes one labor hour to 
prepare a customer notification letter per system and $0.43 in material 
costs per sample for CWSs. EPA assumed one labor hour for NTNCWSs, with 
negligible material costs. It is important to note that the majority of 
small systems are assumed to meet the Lead Action Level and are assumed 
to be on triennial monitoring. Therefore, this requirement will only 
affect them once every three years. The total cost to small systems is 
estimated at $878,000.
6. Activities for Regulatory Change III.F
    Different provisions of Regulatory Change III.F apply to different 
subsets of systems. Most small Community Water Systems will incur costs 
to include a statement on lead on the CCR, at an average cost of $6 per 
system, based on the assumption of 0.25 hours to add an informational 
statement on lead to the CCR. Small Non-Transient Non-Community Water 
Systems that exceed the Lead Action Level will incur costs to modify 
their public notification language, at an average cost per system of 
$83. Small Community Water Systems that exceed the Lead Action Level 
will incur costs from a variety of public education activities, at an 
average cost per system of $348. The total cost for small systems is 
estimated at $517,000.
7. Activities for Regulatory Change III.G
    Regulatory Change III.G applies to systems that have ``tested out'' 
lead service lines as part of a lead service line replacement program 
and then re-exceed the Action Level. For the purposes of subsequent 
lead service line replacement efforts, the previously ``tested out'' 
lines would go back into the inventory for possible re-testing and/or 
replacement. Only a handful of systems are expected to be in this 
situation, estimated at one system per year. There is no evidence that 
small systems would be triggered into this regulatory change cost any 
more frequently than other systems. If this system were a small system, 
a lower number of lead service lines would be replaced or tested out 
than was assumed in the Economic Analysis. The average number of 
service connections per system for systems serving fewer than 10,000 is 
289. For the purposes of the Regulatory Flexibility Analysis we assume 
that all 289 of these service connections are lead service lines. The 
resulting cost per system for the retesting is estimated at $1,311 per 
year for a small system based on the approach described earlier in the 
Economic Analysis for Regulatory Change III.G. The percent assumed to 
be tested out rather than replaced is estimated at 76 percent based on 
one year of data from DC WASA. This means that 76 percent of the 289 
service connection lines would need to be retested over a 15 year 
period.
8. Total Small System Costs
    Table V.6 summarizes the estimated annual costs associated with all 
proposed regulatory changes after those changes have been implemented. 
An additional $7,193,000 in one-time rule implementation costs will 
also be incurred during the three year period prior to implementation 
of the changes.

9. Average Costs Per Small System
    The average compliance cost for all small systems covered by the 
LCR for the proposed rule change is minimal: $50 per system in annual 
costs. However, there is a fairly wide range in the costs that a system 
could face. All systems will incur a $105 one-time cost, but the 
additional annual costs could be as low as $0 for small systems that 
already notify customers of tap monitoring results and who do not 
detect lead in their compliance sampling. Systems that do not already 
notify customers of results will incur a cost of $14 per year. Systems 
that detect any level of lead above the method detection limit of 0.001 
mg/L in their compliance sample will incur a cost of $6 per year to 
include a statement in their CCR. The roughly 1.5 percent of systems 
that are making a treatment change or source addition would incur an 
additional $201 in the year they make the change.
    At the high end, the roughly 1.4 percent of small systems that 
exceed the Action Level would incur an additional $2,440 per year. 
Under the assumptions in the Economic Analysis, only .0015 percent of 
systems (1 per year) could possibly incur both the additional tap 
monitoring costs and lead service line testing costs after an Action 
Level exceedance, at a total cost of $1,311 per year. If a system 
incurred all annual costs, the total would be $3,972 per year.
10. Measuring Significant Impact of Rule Costs
    The costs to small systems are first compared against average 
revenues for small systems from all revenue sources. Small systems can 
be one of three types of small entities--small businesses, small 
governments, or small non-profits. In the Economic Analysis for the 
final Stage 2 Disinfectants and Disinfection Byproducts Rule, EPA 
calculates the average revenues from all revenue sources for small 
systems serving fewer than 10,000 for each of the small entity types 
and then estimates a weighted average revenue from all revenue sources 
based on the proportion of small systems in each type of entity (U.S. 
EPA 2005c). The weighted average revenue from all revenue sources for 
small systems is estimated at $3 million per year.
    Using the average cost of the regulatory changes for small systems, 
the one-time implementation costs represent roughly 0.004 percent of 
annual revenues from all revenue sources. The $50 average annual costs 
represent 0.002 percent of average annual revenues from all revenue 
sources. Roughly 1.4 percent of the systems would incur annual costs of 
$2,440, which is approximately .082 percent of revenues from all 
sources. Only 1 system could face the maximum annual costs of $3,972. 
This maximum cost is approximately 0.13 percent of annual revenues from 
all sources.
    In summary, the costs for the average small system due to the 
regulatory changes are estimated to be less than 1 percent of revenues 
(0.002 percent). In addition, fewer than 100 systems (1 system per 
year) are expected to experience economic impacts of approximately 0.13 
percent of the revenue.
    Based on this analysis, EPA has concluded that the proposed rule 
changes will not have a significant impact on a substantial number of 
small entities.
    Although this proposed rule will not have a significant economic 
impact on a substantial number of small entities, EPA nonetheless has 
tried to reduce the impact of this rule on small entities by 
considering several alternatives to the proposed regulatory changes 
that could minimize impact to small systems while still meeting the 
objectives of the rule.
11. Regulatory Changes III.A
    These changes clarify the original intent of the LCR that very 
small NTNCWSs serving 100 persons or fewer take a minimum of five 
samples for each sampling period, even if the system has fewer than 
five sampling locations. EPA is requesting comment on an option 
suggested by a work group comprised of representatives from EPA's 
regional offices and several States that would limit the number of 
samples these systems would have to take to one for each location 
(i.e., tap). Taking fewer than five samples for each monitoring event 
would reduce the monitoring burden for small systems. However, as 
explained in the preamble to the proposed regulatory changes, EPA 
believes that taking fewer than five samples for a system would likely 
compromise the statistical objectives of monitoring for lead and 
copper.
12. Regulatory Change III.C
    Regulatory Change III.C requires systems that have exceeded the 
Lead Action Level to resume tap monitoring for lead on a regular, 
rather than reduced, schedule. Originally, EPA had considered extending 
this requirement to both lead and copper monitoring. Based on 
suggestions from the work group to minimize impacts on small systems, 
EPA limited the requirement to only Lead Action Level exceedances.
13. Regulatory Change III.E
    Regulatory Change III.E requires systems to provide lead monitoring 
results to consumers. The work group discussed including copper 
monitoring results in the notification, but deferred that suggestion 
for future consideration, thereby limiting the increase in burden for 
small systems. Section H of this proposal also provides some important 
clarifications of alternatives to corrosion control for small systems.
    We continue to be interested in the potential impacts of the 
proposed rule on small entities and welcome comments on issues related 
to such impacts.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.

[[Page 40857]]

    EPA has determined that this rule does not contain a Federal 
mandate that may result in expenditures of $100 million or more for 
State, local, and tribal governments, in the aggregate, or the private 
sector in any one year. The total upfront costs of this action to 
States and public water systems are estimated at $8.8 million, with 
estimated annual costs to States and public water systems ranging from 
approximately $5.1 to $5.5 million. Systems and State/Primacy agencies 
will incur one-time upfront costs associated with reviewing and 
implementing the overall LCR regulatory changes. For systems, 
activities include reviewing the rule changes and training staff. For 
States/Primacy agencies, activities include regulation adoption, 
program development, and miscellaneous training. Systems and States 
will also incur annual costs consisting of the costs to implement the 
regulation. Annual costs to systems include the costs of reporting, 
monitoring, and public education. Annual costs to States consist of the 
costs of reviewing water system information. Thus, this proposal is not 
subject to the requirements of sections 202 and 205 of the UMRA.
    EPA has determined that this rule contains no regulatory 
requirements that might significantly or uniquely affect small 
governments. The regulation applies to all owners/operators of public 
water systems, not uniquely to those owners/operators that are small 
entities, and, for most systems, requires minimal expenditure of 
resources. Since these regulatory revisions affect all system sizes and 
the impact on the average small system will be 0.13 percent of 
revenues, the regulatory revisions to the LCR are not subject to the 
requirements of section 203 of UMRA.
    Nevertheless, in developing this rule, EPA consulted with State and 
local officials (including small entity representatives) early in the 
process of developing the proposed regulation to permit them to have 
meaningful and timely input into its development. EPA held five 
workshops in 2004-2005 to elicit concerns and suggestions from 
stakeholders on various issues related to lead in drinking water. These 
workshops covered the topic areas of simultaneous compliance, sampling 
protocols, public education, lead service line replacement, and lead in 
plumbing. Expert participants from utilities, academia, state 
governments, consumer and environmental groups, and other stakeholder 
groups participated in these workshops to identify issues, propose 
solutions, and offer suggestions for modifications and improvements to 
the LCR. These workshops are described in greater detail in the 
Economic Analysis for this proposed rule.
    The Agency has developed fact sheets that describe requirements of 
the short-term regulatory revisions and clarifications to the LCR. 
These fact sheets are available by calling the Safe Drinking Water 
Hotline at 800-426-4791.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' are defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the National 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of Government.''
    This proposed rule does not have federalism implications. It will 
not have substantial direct effects on the States, on the relationship 
between the national government and the States, or on the distribution 
of power and responsibilities among the various levels of government, 
as specified in Executive Order 13132. The rule is consistent with, and 
only makes revisions to, the requirements under the current national 
primary drinking water regulations for lead and copper. The existing 
rule imposes requirements on public water systems to ensure that water 
delivered to users is minimally corrosive, remove lead service lines 
and provide public education where necessary to ensure public health 
protection. This proposed rule does not make any significant changes to 
these requirements but makes revisions and clarifications to the rule's 
requirements to enhance the efficiency and effectiveness of current 
requirements.
    Nevertheless, EPA did consult with State and local officials early 
in the process of developing the proposed regulation as described in 
section V.D, Unfunded Mandates Reform Act. Several States also 
participated in EPA's workgroup that developed this proposal.
    In the spirit of Executive Order 13132, and consistent with EPA 
policy to promote communications between EPA and State and local 
governments, EPA specifically solicits comment on this proposed rule 
from State and local officials.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.''
    This proposed rule does not have tribal implications as specified 
in Executive Order 13175. It does not significantly or uniquely affect 
the communities of Indian tribal governments, nor does it impose 
substantial direct compliance costs on those communities. The 
provisions of the proposed rule apply to all community and non-
transient non-community water systems. tribal governments may be the 
owners or operators of such systems, however, nothing in this 
proposal's provisions uniquely affects them. EPA therefore concludes 
that this proposed rule does not significantly or uniquely affect the 
communities of Indian tribal governments. Thus, Executive Order 13175 
does not apply to this rule. EPA specifically solicits additional 
comment on this proposed rule from Tribal officials.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    Executive Order 13045: ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies 
to any rule that: (1) Is determined to be ``economically significant'' 
as defined under Executive Order 12866, and (2) concerns an 
environmental health or safety risk that EPA has reason to believe may 
have a disproportionate effect on children. If the regulatory action 
meets both criteria, the Agency must evaluate the environmental health 
or safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    This proposed rule is not subject to the Executive Order because it 
is not economically significant as defined in Executive Order 12866. 
This proposed rule does not change the core LCR requirements in place 
to assure the protection of children from the effects of lead in 
drinking water, rather the proposed changes will improve the 
implementation of these provisions. Moreover, EPA believes that this

[[Page 40858]]

proposal is consistent with Executive Order 13045 because it will 
further strengthen protection to children from exposure to lead and 
copper via drinking water, as this proposal enhances the implementation 
of the LCR in the areas of monitoring, customer awareness, and lead 
service line replacement. This proposal also clarifies the intent of 
some unclear provisions in the LCR. These changes are expected to 
ensure and enhance more effective protection of public health through 
the reduction in lead exposure.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This rule is not a ``significant energy action'' as defined in 
Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355 
(May 22, 2001)) because it is not likely to have a significant adverse 
effect on the supply, distribution, or use of energy. The rule provides 
clarifications and modifications to the existing LCR rule language 
only.
    This proposed rule does not affect the supply of energy as it does 
not regulate power generation. The public and private utilities that 
will be affected by this proposed regulation do not, as a rule, 
generate power. The proposed revisions to the LCR do not regulate any 
aspect of energy distribution as the utilities that are regulated by 
the LCR already have electrical service. Finally, these regulatory 
revisions do not adversely affect the use of energy as EPA does not 
anticipate that a significant number of drinking water utilities will 
add treatment technologies that use electrical power to comply with 
these regulatory revisions. As such, EPA does not anticipate that this 
rule will adversely affect the use of energy.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note) 
directs EPA to use voluntary consensus standards in its regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. The NTTAA directs EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable voluntary consensus standards.
    The proposed rule may involve voluntary consensus standards in that 
it requires additional monitoring for lead and copper in certain 
situations, and monitoring and sample analysis methodologies are often 
based on voluntary consensus standards. However, the proposed rule does 
not change any methodological requirements for monitoring or sample 
analysis, only, in some cases, the required frequency and number of 
samples. Also, EPA's approved monitoring and sampling protocols 
generally include voluntary consensus standards developed by agencies 
such as the American National Standards Institute (ANSI) and other such 
bodies wherever EPA deems these methodologies appropriate for 
compliance monitoring.

Sec.  141.81  Applicability of corrosion control treatment steps to 
small, medium-size and large water systems.

* * * * *
    (b) * * *
    (3) * * *
    (iii) * * *
    Any water system deemed to have optimized corrosion control 
pursuant to this paragraph shall notify the State in writing pursuant 
to Sec.  141.90(a)(3) of any upcoming change in treatment or addition 
of a new source. The State must review and approve the addition of a 
new source or change in water treatment before it is implemented by the 
water system.
* * * * *
    (e) * * *
    (1) * * * A system exceeding the lead or copper action level shall 
recommend optimal corrosion control treatment (Sec.  141.82(a)) within 
six months after the end of the monitoring period during which it 
exceeds one of the action levels.
    (2) Step 2: Within 12 months after the end of the monitoring period 
during which a system exceeds the lead or copper action level, the 
State may require the system to perform corrosion control studies 
(Sec.  141.82(b)). * * *
    (i) For medium-size systems, within 18 months after the end of the 
monitoring period during which such system exceeds the lead or copper 
action level.
    (ii) ``For small systems, within 24 months after the end of the 
monitoring period during which such system exceeds the lead or copper 
action level.''
* * * * *
    4. Section 141.83(a)(1) is revised to read as follows:


Sec.  141.83  Source water treatment requirements.

* * * * *
    (a) * * * (1) Step 1: A system exceeding the lead or copper action 
level shall complete lead and copper source water monitoring (Sec.  
141.88(b)) and make a treatment recommendation to the State (Sec.  
141.83(b)(1)) no later than 6 months after the end of the monitoring 
period during which the lead or copper action level was exceeded.
* * * * *
    5. Section 141.84 is amended as follows by:
    a. Redesignating paragraph (b) as (b)(1);
    b. Revising the last sentence in the newly designated (b)(1) and 
adding two sentences to the end of the paragraph;
    c. Adding paragraph (b)(2); and
    d. In paragraph (f), revise ``(b)'' to read ``(b)(2)''.


Sec.  141.84  Lead service line replacement requirements.

* * * * *
    (b)(1) * * * The first year of lead service line replacement shall 
begin on the date after the monitoring period in which the action level 
was exceeded under paragraph (a) of this section. If monitoring is 
required annually or less frequently, the end of the monitoring period 
is September 30 of the calendar year in which the sampling occurs. If 
the State has established an alternate monitoring period, then the end 
of the monitoring period will be the last day of that period.
    (2) Any water system resuming a lead service line replacement 
program shall update its inventory of lead service lines to include 
those sites that were previously determined not to require replacement 
through the sampling provision under paragraph (c) of this section. The 
system will then divide the updated number of remaining lead service 
lines by the number of remaining years in the program to determine the 
number of lines that must be replaced per year (7 percent replacement 
is based on a 15-year replacement program, so, for example, systems 
resuming after conducting two years of replacement would divide the 
updated inventory by 13).
* * * * *
    6. Section 141.85 is revised to read as follows:


Sec.  141.85  Public education and supplemental monitoring 
requirements.

    A water system that exceeds the Lead Action Level based on tap 
water samples collected in accordance with Sec.  141.86 shall deliver 
the public education materials contained in paragraph (a) of this 
section in accordance with the requirements in paragraph (b) of this 
section. Water systems that exceed the Lead Action Level must sample 
the tap water of any customer who requests it in accordance with 
paragraph (c) of this section. All water systems must provide a 
consumer notice of lead tap water monitoring results to persons served 
by the water system at sites that are tested, as specified in paragraph 
(d) of this section.
    (a) Content of written public education materials.--(1) Community 
water systems and Non-transient non-community water systems. Water 
systems must include the following elements in printed materials (such 
as brochures and pamphlets) in the same order as listed below. In 
addition, paragraphs (a)(1)(i)-(ii) and (a)(1)(vi) must be included 
exactly as written except for the text in brackets in these paragraphs 
for which the water system must include system-specific information. 
Any additional information presented by a water system must be 
consistent with the information below and be in plain language that can 
be understood by lay people.
    (i) Opening Statement. IMPORTANT INFORMATION ABOUT LEAD IN YOUR 
DRINKING WATER. [INSERT NAME OF WATER SYSTEM] found high levels of lead 
in drinking water in some homes/buildings. Lead can cause serious 
health problems, especially for pregnant women and children 6 years and 
under. Please read this notice closely to see what you can do to reduce 
lead in your drinking water.
    (ii) Health effects of lead. Lead can cause serious health problems 
if too much enters your body. It can cause damage to the brain and 
kidneys and can decrease the number of red blood cells (a risk factor 
for anemia). The greatest risk is to infants, young children, and 
pregnant women. Small amounts slow down normal mental development in 
growing children and alter the development of other organs and systems. 
The effects of lead on the brain are associated with lowered IQ in 
children. Adults with kidney problems and high blood pressure are more 
likely to be affected by low levels of lead than the general 
population. Lead is stored in the bones allowing it to be released even 
after exposure stops. The presence in

[[Page 40860]]

bone increases the concern for exposure at all points of the life 
cycle.
    (iii) Sources of Lead. (A) Explain what lead is.
    (B) Explain possible sources of lead and how lead enters drinking 
water. Include information on home/building plumbing and service lines 
that may contain lead.
    (C) Discuss other important sources of lead exposure in addition to 
drinking water (e.g., paint).
    (iv) Steps you can take to reduce your exposure to lead in drinking 
water. (A) Encourage running the water to flush out the lead.
    (B) Explain concerns with using hot water and specifically caution 
against the use of hot water for baby formula.
    (C) Explain that boiling water does not reduce lead levels.
    (D) Discuss other options consumers can take to reduce exposure to 
lead in drinking water, such as alternative sources or treatment of 
water.
    (v) What happened and What is being done?
    (A) Explain why there are high levels of lead in the system's 
drinking water (if known).
    (B) Discuss what the water system is doing to reduce the lead 
levels in homes/buildings in this area.
    (vi) For More Information. Call us at [INSERT YOUR NUMBER], or 
visit our web site at [INSERT YOUR WEB SITE HERE IF APPLICABLE]. For 
more information on reducing lead exposure around your home/building 
and the health effects of lead, visit EPA's Web site at www.epa.gov/lead, call the National Lead Information Center at 1-800-424-LEAD, or 
contact your health care provider.
    (2) Community water systems. In addition to including the elements 
specified in paragraph (a)(1) of this section, community water systems 
must:
    (A) Tell consumers how to get their water tested.
    (B) Discuss lead in plumbing components and the difference between 
low lead and lead free.
    (b) Delivery of public education materials. (1) In communities 
where a significant proportion of the population speaks a language 
other than English the system must also provide the public education 
materials in the appropriate language(s).
    (2) A community water system that exceeds the Lead Action Level on 
the basis of tap water samples collected in accordance with Sec.  
141.86, and that is not already conducting public education tasks under 
this section, must, within 60 days after the end of the monitoring 
period in which the exceedance occurred:
    (i) Deliver printed materials meeting the content requirements of 
paragraph (a) of this section to all bill paying customers.
    (ii) Make a good faith effort to contact all customers who are most 
at risk by delivering materials that meet the content requirements of 
paragraph (a) of this section to the following organizations along with 
a cover letter that encourages distribution by the organization to all 
its potentially affected customers or users.
    (A) Local Public Health Agencies--The water system must deliver 
materials that meet the content requirements of paragraph (a) of this 
section to the local public health agencies and must directly contact 
(by phone or in person) the local public health agencies. The local 
public health agencies may provide a specific contact list of 
additional community based organizations serving targeted populations.
    (B) Public and private schools or school boards.
    (C) Licensed childcare centers.
    (D) Public and private pre-schools.
    (E) Women Infants and Children (WIC) and Head Start programs.
    (F) Public and private hospitals and medical clinics.

determined in consultation with the State.
    (A) Public Service Announcements.
    (B) Paid advertisements.
    (C) Display Information in Public Areas.
    (D) Internet such as emails to customers.
    (E) Public Meetings.
    (F) Delivery to every household.
    (G) Individual contact with customers (targeted contact).
    (H) Provide materials directly to all multi-family homes and 
institutions.
    (I) Other methods approved by the State.
    (vii) For systems that are required to conduct monitoring annually 
or less frequently, the end of the monitoring period is September 30 of 
the calendar year in which the sampling occurs, or, if the State has 
established an alternate monitoring period, the last day of that 
period.
    (3) As long as a system exceeds the action level, it must repeat 
the activities described in paragraph (b)(2) of this section as 
described in (b)(3)(i)-(iv) of this section.
    (i) A community water system shall repeat the tasks contained in

the state. The State can allow activities in (b)(2)(iii) and (b)(2)(vi) 
of this section to extend beyond the 60-day requirement if needed for 
implementation purposes; however, this extension must be approved in 
writing by the State in advance of the 60-day deadline.
    (4) Within 60 days after the end of the monitoring period in which 
the exceedance occurred (unless it already is repeating public 
education tasks pursuant to paragraph (b)(5) of this section), a non-
transient non-community water system shall deliver the public education 
materials specified by paragraph (a) of this section as follows:
    (i) Post informational posters on lead in drinking water in a 
public place or common area in each of the buildings served by the 
system; and
    (ii) Distribute informational pamphlets and/or brochures on lead in 
drinking water to each person served by the non-transient non-community 
water system. The State may allow the system to utilize electronic 
transmission in lieu

[[Page 40861]]

of or combined with printed materials as long as it achieves at least 
the same coverage.
    (iii) For systems that are required to conduct monitoring annually 
or less frequently, the end of the monitoring period is September 30 of 
the calendar year in which the sampling occurs, or, if the State has 
established an alternate monitoring period, the last day of that 
period.
    (5) A non-transient non-community water system shall repeat the 
tasks contained in paragraph (b)(4) of this section at least once 
during each calendar year in which the system exceeds the Lead Action 
Level.
    (6) A water system may discontinue delivery of public education 
materials if the system has met the Lead Action Level during the most 
recent six-month monitoring period conducted pursuant to Sec.  141.86. 
Such a system shall recommence public education in accordance with this 
section if it subsequently exceeds the Lead Action Level during any 
monitoring period.
    (7) A community water system may apply to the State, in writing, 
(unless the State has waived the requirement for prior State approval) 
to use only the text specified in paragraph (a)(1) of this section in 
lieu of the text in paragraphs (a)(1) and (a)(2) of this section and to 
perform the tasks listed in paragraphs (b)(4) and (b)(5) of this 
section in lieu of the tasks in paragraphs (b)(2) and (b)(3) of this 
section if:
    (i) The system is a facility, such as a prison or a hospital, where 
the population served is not capable of or is prevented from making 
improvements to plumbing or installing point of use treatment devices; 
and
    (ii) The system provides water as part of the cost of services 
provided and does not separately charge for water consumption.
    (8) A community water system serving 3,300 or fewer people may 
limit certain aspects of their public education programs as follows:
    (i) With respect to the requirements of paragraph (b)(2)(vi) of 
this section, a system serving 3300 or fewer must implement at least 
one of the activities listed in that paragraph.
    (ii) With respect to the requirements of paragraph (b)(2)(ii) of 
this section, a system serving 3300 or fewer people may limit the 
distribution of the public education materials required under that 
paragraph to facilities and organizations served by the system that are 
most likely to be visited regularly by pregnant women and children.
    (iii) With respect to the requirements of paragraph (b)(2)(v) of 
this section, the State may waive this requirement for systems serving 
3300 or fewer persons as long as system distributes notices to every 
household served by the system.
    (c) Supplemental monitoring and notification of results. A water 
system that fails to meet the Lead Action Level on the basis of tap 
samples collected in accordance with Sec.  141.86 shall offer to sample 
the tap water of any customer who requests it. The system is not 
required to pay for collecting or analyzing the sample, nor is the 
system required to collect and analyze the sample itself.
    (d) Notification of results--(1) Reporting requirement. All water 
systems must provide a consumer notice of lead tap water monitoring 
results carried out to meet requirements under Sec.  141.86 to all 
persons served by the water system at the sampling sites in Sec.  
141.86(c).
    (2) Timing of notification. A water system must provide the 
consumer notice as soon as practical, but no later than 30 days after 
the system learns of the tap monitoring results.
    (3) Content. The consumer notice must include the results of lead 
tap water monitoring for the tap that was tested, an explanation of the 
health effects of lead, list steps consumers can take to reduce 
exposure to lead in drinking water and contact information for the 
water utility. The notice must also provide the maximum contaminant 
level goal and the action level for lead and the definitions for these 
two terms from Sec.  141.153(c)(1).
    (4) Delivery. The consumer notice must be provided to all persons 
served at the site by mail or other methods approved by the State. The 
system must provide the notice to all customers, including consumers 
who do not get water bills.
    7. Section 141.86 is amended as follows:
    a. In the introductory paragraph of (c), adding a sentence after 
the third sentence;
    b. In paragraph (d)(4)(i) add as the last sentence;
    c. Revising paragraph (d)(4)(ii);
    d. Revising paragraph (d)(4)(iii);

    h. Removing the first sentence in paragraph (d)(4)(vii), and adding 
in its place the following two sentences;
    i. In paragraph (g)(4)(i) adding as the last sentence; and
    j. Revising paragraph (g)(4)(iii).


Sec.  141.86  Monitoring requirements for lead and copper in tap water.

* * * * *
    (c) * * * A non-transient non-community public water system that 
serves 100 people or less and that does not have enough drinking water 
taps meeting the sample site criteria of Sec.  141.86(a) to reach the 
required number of sample sites listed in Sec.  141.86(c) must collect 
at least one sample from each tap and then must collect additional 
samples from those taps on different days during the monitoring period 
to meet the required number of sites. * * *
* * * * *
    (d) * * *
    (4) * * *
    (i) * * * This sampling shall begin during the calendar year 
immediately following the end of the second consecutive six-month 
monitoring period.
    (ii) Any water system that meets the Lead Action Level and 
maintains the range of values for the water quality control parameters 
reflecting optimal corrosion control treatment specified by the State 
under Sec.  141.82(f) during each of two consecutive six-month 
monitoring periods may reduce the frequency of monitoring to once per 
year and reduce the number of lead and copper samples in accordance 
with paragraph (c) of this section if it receives written approval from 
the State. This sampling shall begin during the calendar year 
immediately following the end of the second consecutive six-month 
monitoring period. The State shall review monitoring, treatment, and 
other relevant information submitted by the water system in accordance 
with Sec.  141.90, and shall notify the system in writing when it 
determines the system is eligible to commence reduced monitoring 
pursuant to this paragraph. The State shall review, and where 
appropriate, revise its determination when the system submits new 
monitoring or treatment data, or when other data relevant to the number 
and frequency of tap sampling becomes available.
    (iii) A small or medium-size water system that meets the lead and 
copper action levels during three consecutive years of monitoring may 
reduce the frequency of monitoring for lead and copper from annually to 
once every three years. Any water system that meets the Lead Action 
Level and maintains the range of values for the water quality control 
parameters reflecting optimal corrosion control treatment specified by 
the State under Sec.  141.82(f) during three consecutive years of 
monitoring may reduce the frequency of monitoring from annually to once 
every three years if it receives

[[Page 40862]]

written approval from the State. Samples collected once every three 
years shall be collected no later than every third calendar year. The 
State shall review monitoring, treatment, and other relevant 
information submitted by the water system in accordance with Sec.  
141.90, and shall notify the system in writing when it determines the 
system is eligible to reduce the frequency of monitoring to once every 
three years. The State shall review, and where appropriate, revise its 
determination when the system submits new monitoring or treatment data, 
or when other data relevant to the number and frequency of tap sampling 
becomes available.
    (iv) * * *
    (A) The State, at its discretion, may approve different period for 
conducting the lead and copper tap sampling for systems collecting a 
reduced number of samples. This sampling shall begin no later than the 
six-month period beginning January 1 of the calendar year following the 
reduced monitoring exceedance. Such a period shall be no longer than 
four consecutive months and must represent a time of normal operation 
where the highest levels of lead are most likely to occur. For a non-
transient non-community water system that does not operate during the 
months of June through September, and for which the period of normal 
operation where the highest levels of lead tare most likely to occur is 
not known, the State shall designate a period that represents a time of 
normal operation for the system. This sampling shall begin during the 
calendar year immediately following the end of the second consecutive 
six-month monitoring period for systems resuming annual monitoring and 
during the three-year period following the end of the third consecutive 
calendar year of annual monitoring for systems resuming triennial 
monitoring.
    (B) Any water system subject to the reduced monitoring frequency 
that fails to meet the Lead Action Level during any four-month
