## Report of the Lead and Copper Rule Working Group to the National Drinking Water Advisory Council

1. Executive Summary

The Lead and Copper Rule Working Group (LCRWG) of the National Drinking Water Advisory Council (NDWAC) has completed its deliberations on issues associated with long term revisions to the Lead and Copper Rule (LCR) . This report includes the group’s findings and recommendatio ns.

This executive summary provides a brief overview of the report. Details of the findings and recommendations are provided in the body of the report. A list of the members of the working group can be found in Appendix A.

1.1. Charge

The charge to the L CRWG was to provide advice to the NDWAC as it develops recommendations for the U.S. Environmental Protection Agency (EPA) on targeted issues related to long term revisions to the Lead and Copper Rule under the Safe Drinking Water Act (SDWA)

.

1.2. Findings and Recommendations

The anticipated Long Term Revisions to the Lead and Copper Rule (LTR LCR) is a very important opportunity for removing sources of lead in contact with drinking water and for reducing exposure to lead from drinking water in the meantime. Creative financing and robust public education also are essential.

The LCRWG took the following considerations, among others, into account in making recommendations

for revisions to the LCR. A more detailed list of considerations is included in the full report.

T here is no safe level of lead. Lead can pose health risks to anyone, but there are heightened risks for pregnant women, infants and young children and other vulnerable populations with both acute and chronic exposures

. Effective elimination of lead ed materials in contact with water and minimization of exposure to lead in drinking water is a shared responsibility ; public water systems ( PWSs ) , consumers, building owners, public health officials and others each have important roles t o play

. T he lack of resources to reduce the sources of exposure in some communities , however, also rais es important questions of disparate impact and environmental justice. Thus, creative financing mechanisms will be

needed.

The LCR should remain a tre atment technique rule, but it can be improved based on the scient ific knowledge that has emerged since the current LCR was promulgated . Corrosion control treatment is complicated, and will vary based on specific circumstances in each public water system. Thus, regular updates to guidance by EPA based on the latest science and the creat ion of a national clearinghouse of information both for the public and for PWSs are needed.

The LCRWG considered but did not quantify the cost implic ations of its recommendations. An important factor in the group’s deliberations was the principle that PWS and state resources should be focused on actions that achieve the greatest public health protection

. Recognizing that lead service line (LSL) replacement program s will be costly in some locations, t he LCRWG also encourages PWSs to incorporateReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

6 anticipated costs into their capital improvement program as appropriate to their situation

, and urges states

to include the costs of LSL replacement in their criteria for all ocation of Drinking Water State Revolving

Funds.

The LCRWG specifically recommends that EPA revise the LCR to :

• Require pro active lead service line ( LSL ) replacement programs

, which set replacement goals, effectively engage customers in implementing those goals

, and provid e improv ed access to
information about LSL s
, in place of current requirements in which LSLs must be replaced only after a lead action level (AL) exceedance ;

• Establish more robust public education requirements for le ad and LSLs

, by updating the Consumer Confidence Report (CCR) , a dding targeted outreach to consumers with lead service lines and other vulnerable populations (pregnant women and families with infants and young children) , and increasing the information avai lable to the public ;

• Strengthen corrosion control treatment ( CCT ) , retaining the current rule requirements to re

- assess CCT if changes to source water or treatment are planned, adding a requirement to review updates to EPA guidance to determine if new scientific information warrants changes ;

• Modif y monitoring requirements to provide for consumer requested tap samples for lead and to

utilize results of tap samples for lead to inform consumer action to reduce the risks in their

homes , to inform the approp riate public health agency when results are above a designated household action level, and to assess the effectiveness of CCT and/or other reasons for elevated

lead results ;

• T ailor water quality parameters (WQPs) to the specific CCT plan for each system, and increase the frequency of WQP monitoring for process control ;

• Establish a health

- based, household action level that triggers a report to the consumer and to the applicable health agency for follow up ;

• S eparate the requirements for copper from those fo r lead and focus new requirements where water is corrosive to copper ; and

• Establish appropriate compliance and enforcement mechanisms

.

A lthough leadership by EPA is essential, reduction of exposure to lead in drinking water cannot be achieved by EPA regulation alone. Thus, this report also includes recommendations for renewed commitment, cooperation and effort by government at all levels and by the general public . We urge EPA to play a leadership role not only in the revis ions to the LCR but also in educating, motivating, and supporting the work of other EPA offices; federal state and local agencies and other stakeholders

. (See

Section 4 : Complementary Actions Critical to the Success of the National Effort to Reduce Lead in Drinking Water.)



### 2. Considerations and Background Information

2.1. Considerations in Preparing this Report

The members of the LCRWG brought different perspectives and expertise to the preparation of this report. Although not all members agreed with each and every consideration listed below, the LCRWG took one another’s perspectives into account and, thus, the following concepts collectively underlie the recommendations in this report

. Additional detail is provided in the recommendations section below.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

7 • Th ere is no safe level of lead. Lead can pose health risks to anyone, but there are heightened

risks for pregnant women, infants and children with both acute and chronic exposures

.

• L ead

- bearing plumbing materials in contact with drinking water pose a ri sk at all times (not just when there is a lead action level (LAL) exceedance).

• Effective elimination of lead ed materials in contact with water and minimization of exposure to lead in drinking water is a shared responsibility. PWSs, consumers, building owners, public health officials and others each have important roles to play.

• The LTR LCR is a n important oppor tunity for removing sources of lead in contact with drinking water and for reducing exposure to lead from drinking water in the meantime. However, additional action beyond the scope of the Safe Drinking Water Act is needed. R emoving lead from drinking wa ter systems also will require renewed commitment, cooperation and effort by government at all levels and by the general public. (See Section 4 : Complementary Actions Critical to the Success of the National Effort to Reduce Lead in Drinking Water.)

• Proa ctive action is needed to remove the sources of lead, with appropriate incentives both for

PWSs and their customers needed to encourage such action

.

• Successful implementation of the revised LCR can only take place in the context of a more

holistic effort on lead in water issues involving stakeholders other than just EPA and water systems, and resources beyond those able to be brought to bear by water systems. Partnerships at all levels are essential. Recognizing that public agency budgets are tighter tha n ever, greater engagement by local health agencies, those funding housing programs, and those involved in permitting and construction is particularly important.

• Creative financing mechanisms also will be needed to achieve this goal for all individuals

pot entially exposed to lead, regardless of race, ethnicity or income. Leaving a lead service line in place because a low

- income resident does not have the means to pay raises serious questions of disparate impact and environmental justice.

• The public plays a critical role in protecting their families’ health by reducing exposure to lead and copper, and informing the public enables them to be effective participants in implementing their share of the responsibility.

• The issues associated with lead and copper are very different and warrant more separate attention than has been the case in the past

.

• The LCR should remain a treatment technique rule, but it can be improved

.

• C orrosion control treatment (CCT) is complex

, dynamic, and varies based on the circumst ances in each PWS. The understanding of the challenges with CCT has improved in recent years, but questions still remain.

• Attention to unintended consequences is important generally and, in particular, with respect to

CCT

.

• The presence of lead

- bearing materials in premise plumbing raises issues about what systems can implement in customers’ homes

.

• Attention to what States are able to oversee and enforce also is important.

• PWS and state resources should be focused on actions that achieve the greates t p ublic health protection

.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

8 2.2 Regulatory Background and Formation of the NDWAC Lead and Copper Work Group

Under the Safe Drinking Water Act EPA sets public health goals and enforceable standards for drinking water quality. 1 The Lead and Copper Rule is a treatment technique rule. Instead of setting a maximum contaminant level (MCL) for lead or copper, the rule requires (PWSs) to take certain actions to minimize lead and copper in drinking water, to reduce water corrosivity an d prevent the leaching of these metals from the premise plumbing and drinking water distribution system components and w hen that isn’t enough, to replace lead service lines under their control

. The current rule sets an action level (AL) , or concentration, of 0.015 mg/L for lead and 1.3 mg/L for copper. An AL is not the same as an MCL. An

MCL is based on health effects and feasibility ; whereas an action level is a screening tool for determining when certain treatment technique actions ar e needed.

T he LCR action level is based on the practical feasibility of reducing lead through controlling corrosion. In the LCR, if the AL is exceeded in more than ten percent of tap water samples collected during any monitoring period (i.e., if the 90 t h percentile level is greater than the AL ), it is not a violation, but triggers other requirements that include water quality parameter monitoring, corrosion control treatment (CCT), source water monitoring/treatment, public education, and lead service lin e replacement (LSLR). The rule also requires States to report the 90 th percentile for lead concentrations to EPA’s Safe Drinking Water Information System (SDWIS) database for all water systems serving 3,300 or more persons, and for those systems serving fe wer than 3,300 persons only when the lead action level (LAL) is exceeded. States only report the 90 th percentile for copper concentrations in SDWIS when the copper action level is exceeded in water systems regardless of the size of the service population. Public education requirements ensure that drinking water consumers receive meaningful, timely, and useful information that is needed to help them limit their exposure to lead in drinking water.

Copper is a common material used in household plumbing and drinking water service lines in the United States. Copper is an essential nutrient in small amounts; however, acute ingestion of excess copper in drinking water has been associated with adverse health effects, including acute gastrointestinal symptoms

such as abdominal discomfort, nausea, and vomiting.

The SDWA requires EPA to set MCLGs at concentration levels at which no known or anticipated adverse effects would occur, allowing for an adequate margin of safety. EPA proposed an MCLG of 1.3 mg/l for

copper in 1985, and finalized that MCLG in 1991 when the LCR was promulgated. The LCR set the action level (AL) for copper, the level at which treatment technique actions are triggered for the water system, equal to the MCLG. The AL is triggered if the 90 th percentile level of water samples is exceeded. All community water systems must report the 90 th percentile level and the number of samples that

exceeded the 90 th percentile in their Consumer Confidence Reports.

In early 2004, EPA began a wide

- ranging rev iew of the implementation of the LCR to determine if there was a national problem related to elevated levels of lead in drinking water. As part of its national review, EPA collected and analyzed lead concentration data and other information, carried out a review of implementation in States, held four expert workshops to discuss elements of the regulations, and worked to understand local and State efforts to monitor for lead in school drinking water, including a national meeting to discuss challenges and nee ds. EPA released a Drinking Water Lead Reduction Plan (DWLRP) in March 2005. This plan outlined short

- term and long

- term goals for improving implementation of the

9 LCR. The plan can be found at the following web address: http://water.epa.gov/lawsregs/rulesregs/sdwa/lcr/lead_review.cfm

In 2007, EPA promulgated regulations, which addressed the short

- term revisions to the LCR that were identified in the 2005 DWLRP. These requir ements enhanced the implementation of the LCR in the areas of monitoring, treatment, LSLR, public education, and customer awareness . These revisions were intended to better ensure drinking water consumers receive meaningful, timely, and useful information needed to help them limit their exposure to lead in drinking water.

A number of Safe Drinking Water Act (SDWA) amendments aim to reduce lead in drinking water by limiting the amount of allowable lead in plumbing materials that come into contact with drin king water. In 1986, the SDWA was amended to prohibit the “use of any pipe, any pipe or plumbing fitting or fixture, any solder, or any flux, in the installation or repair of (i) any public water system; or (ii) any plumbing in

a residential or non

- residen tial facility providing water for human consumption, that is not lead free”. Lead Free was defined as solder and flux with no more than 0.2% lead and pipes with no more than 8%

lead.

Congress again amended the SDWA in 1996, to prohibit the introduction into commerce of any pipe, pipe or plumbing fitting or fixture that is not lead free and to also require pipes, pipe or plumbing fittings or fixtures be in compliance with 3 rd party lead leaching standards. These provisions ensure that only products meeting the lead free definition are sold in the U.S. and that pipes, pipe or plumbing fittings or

fixtures are certified to be lead free.

The Reduction of Lead in Drinking Water Act of 2011 revised the maximum allowable lead content from not more than 8% to not more than a weighted average of 0.25% lead and included a calculation procedure for determining the weighted average; further reducing the amount of lead in contact with

dr inking water. It also eliminates the federal requirement to comply with the lead leaching standard and included exemptions from the lead free definition for plumbing devices that are used exclusively for non

potable services and also for specific plumbing devices such as toilets, bidets and urinals. The Community Fire Safety Act of 2013 further amended the SDWA to add fire hydrants to the list of exempted plumbing devices.

EPA has continued to work on the long

- term issues that required additional data co llection, research, analysis, and full stakeholder involvement, which were identified in the 2005 DWLRP and the 2007 rule revisions. This action is referred to as the LCR Long

- T erm Revisions (LTR)

. The LCR LTR would apply to all community water systems (CW Ss) and non

- transient non

- community water systems (NTNCWSs). In this report, the term public water system (PWS) is meant to refer to both of these categories but not to

transient non

- community water systems.

Seeing the need for additional input on potential revisions to the Lead and Copper Rule, EPA requested

that t he National Drinking Water Advisory Committee (NDWAC) form the Lead and Copper Rule Working Group (LCRWG) to consider several key questions for the LCR LTR, taking into consideration previous input. The LCRWG met seven times in 2014 and 2015 to produce this report, and sought input from the NDWAC in advance of the last meeting to understand and address quest ions the NDWAC might

have about the working group’s recommendations

.

### 3. Recommendations for Revisions to the Lead and Copper Ru le

The long term revisions to the LCR is a n important opportunity for removing sources of lead in contact with drinking water and for reducing exposure to lead from drinking water in the meantime. Creative financing and robust public education also are essential.

The LCRWG offers the following recommendations, based on information provided to the work group and on the work group’s own deliberations. The LCRWG considers these re commendations to be an integrated package, not a menu of choices from which some recommendations can be selected and combined with others. This package reflects a concerted attempt to strengthen public health protection, which includes targeting the resou rces available to PWSs for the greatest public health value. While individual members might differ on specific recommendations, the work group ( with one dissent ) agrees that this package of recommendations constitutes an improvement over the current LCR.

The LCRWG carefully considered the information and questions posed by EPA in a white paper prepared for the working group. In its deliberations, the LCRWG came to the conclusion that the lessons learned from the implementation of the current LCR warrant ed a fresh look at the premises of the regulation. To truly solve the problem of exposure to lead in drinking water, the LCRWG concluded that lead

- bearing materials should be removed from contact with drinking water to the greatest degree possible, while minimizing the risk of exposure in the meantime. That premise has led to a different paradigm for a

revised LCR and, thus, to a somewhat different set of assumptions than underlay questions posed to the working group

.

The diagram on page 1 2 illustrates the conceptual framework of the recommendations that follow.

The LCRWG specifically recommends that EPA revise the LCR to :

• Require proactive LSL replacement programs, which set replacement goals, effectively engage customers in implementing t hose goals, and provide improved access to information about LSL s
, in place of current requirements in which lead service lines (LSLs) must be replaced only after a lead action level (AL) exceedance and CCT;

• Establishes more robust public education, by cre ating a national clearinghouse of information for the public and templates for PWSs, by updating the Consumer Confidence Report, adding targeted outreach to consumers with lead service lines and other vulnerable populations (pregnant

women and families wit h infants and young children) , and increasing the information available to health care providers and the public;

• Strengthen corrosion control treatment (CCT), retaining the current rule requirements to re

- assess CCT if changes to source water or treatment are planned, adding a requirement to review updates to EPA guidance to determine if new scientific information warrants changes;

• Modify monitoring requirements to provide for consumer requested tap samples for lead and to utilize results of tap samples for lead to inform consumer action to reduce the risks in their

homes , to inform the appropriate public health agency when results are above a designated household action level, and to assess the effectiveness of CCT and/or other reasons for elevated

lead res ults ;

• T ailor water quality parameters to the specific CCT plan for each system, and increases the frequency of WQP monitoring for process control;Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

11 • Establish a health

- based, household action level that triggers a report to the consumer and to the applicabl e health agency for follow up;

• Separate the requirements for copper from those for lead and focus new requirements where water is corrosive to copper; and

• Establish appropriate compliance and enforcement mechanisms.

A lthough leadership by EPA is essential, reduction of exposure to lead in drinking water cannot be achieved by EPA regulation alone. Thus, this report also includes recommendations for renewed commitment, cooperation and effort by government at all levels and by the general public. We urge EPA to play a leadership role not only in the revisions to the LCR but also in educating, motivating, and supporting the work of other EPA offices; federal, state and local agencies and other stakeholders

. (See

Section 4 : Complementary Actions Critical to the Success of the National Effort to Reduce Lead in Drinking Water.)12 Figure 113 3.1. Replace Lead Service Lines 2

Removing the sources of lead in drinking wa ter should be a national goal. More proactive action than has taken place to date is needed to a chieve it

.

Although success in achieving this goal will require a concerted effort by many and can not be accomplished solely through the authorities provided under the Safe Drinking Water Act, revisions to the Lead and Copper Rule are an important component to achieving thi s goal and sh ould be structured accordingly. [See Section 4 for recommendations that complement revisions to the LCR.]

The existing LCR has not creat ed sufficient incentives to fully replace LSLs and other sources of lead

, because LSL replacement is only required when the lead AL has been exceeded and optimizing CCT is insufficient to bring a system back under the action level . Systems that do not exceed the lead A L will never have to implement a LSL replacement program. Further

, the link to actio n level exceedance does not allow adequate time for a well

- planned LSLR program, and a significant unintended consequence where systems have had to implement a LSL replacement program quickly has been an increase in partial LSL replacement

.

EPA asked th e Science Advisory Board (SAB) to evaluate the current scientific data regarding the effectiveness of PLSLR and the review centered around five issues: (1) associations between PLSLR and blood lead levels in children; (2) lead tap water sampling data befor e and after PLSLR; (3) comparisons between partial and full LSLR; (4) PLSLR techniques; and (5) the impact of galvanic corrosion. The SAB found that the quantity and quality of the available data are inadequate to fully determine the effectiveness

of PLSLR in reducing drinking water lead concentrations. The small number of studies available had major limitations (small number of samples, limited follow

- up sampling, lack of information about the sampling data, limited comparability between studies, etc.) for fully evaluating PLSLR efficacy.

While r ecognizing the limits to current data, the SAB concluded that PLSLRs have not been shown to reliably reduce drinking water lead levels in the short

- term, ranging from days to months, and potentially even longer. A dditionally, PLSLR is frequently associated with short

- term elevated drinking water lead levels for some period of time after replacement, suggesting the potential for harm, rather than benefit during that time period. The available data suggest that the e levated tap water lead levels tend to increase then gradually stabilize over time following PLSLR, sometimes at levels below and sometimes at levels similar to those observed prior to PLSLR. The SAB also concluded that in studies comparing full LSLR

versus PLSLR, the evaluation periods were too short to fully assess differential reductions in drinking water lead levels. However, the SAB explained that full LSLR appears generally effective in achieving long

- term reductions in drinking water lead levels, unli ke PLSLR. Both full LSLR and PLSLR generally result in elevated lead levels for a variable period of time after replacement. The limited evidence available suggests that the duration and magnitude of the elevations may be greater with PLSLR than full

LSLR.

T aking all of these considerations into account, t he LCRWG has concluded that an effective framework for replacement of LSLs would include the following and , thus, the LCR should be revised accordingly:

2 40 CFR 141.2 defines: “ Lead service line means a service made of lead which connects the water main to the building inlet and any lead pigtail, gooseneck or o ther fitting which is connected to such lead line.”Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

14 • Requiring all PWSs to establish a LSL replacement program that effectively informs and engages

customers to share appropriately in fully removing LSLs

, unless they can demonstrate that LSLs are not present in their system;

• Modifying the definition of lead service lines to incl ude any service line where any portion, including a lead pigtail, gooseneck or other fitting, is made of lead;

• Clear guidance, case studies, and templates for LSL replacement programs, including a toolkit of

ideas for creative financing strategies;

• Targete d outreach to customers with LSLs , with information about the risks of lead exposure, an offer to test a tap sample, and information about and encouragement to participate in the LSL replacement program ;

• Dates by which systems should have met interim goals and completed replacement of all LSLs

and P LS Ls, without penalty to PWSs for those homeowners who refuse to participate in the replacement program as long as the PWS has made a meaningful effort to work with such a homeowner;

• Creating incentives for u nde rstanding where LSLs and PLSLs exist, while making action on full replacement

, rather than on investigation of the location of LSLs and PLSLs the priority;

• Maintaining ongoing

- outrea c h to homeowners where LSLs or PLSLs still exist;

• Implementation of s tandard operating procedures (SOPs) , either from EPA guidance or tailored to

the system, that helps defin e operations that disturb LSLs and practices to minimize disturbance and consumer exposure to lead ;

• Stronger programs to educate consumers, and to prov ide test results of tap samples at the request

of consumers ;

• Focus efforts on action to replace LSLs rather than on the time and expense of upfront plan approval and on using simplified reporting to the states so they would only need to intervene when pro blems arise ; and

• Requirements that provide strong encouragement for full LSL replacements, with the understanding that there may be justifiable exceptions and that those exceptions would occur only

after the effort s outlined in the r ecommendations below on the part of the PWS to work with customers to complete a full LSL replacement. Such exceptions might include emergency repairs where property owners have refused to participate in a full LSL replacement; during a main replacement project; or when a sufficiently high percentage of property owners participate in an

area

- wide LSL replac ement project to justify replacing LSLs to the property lines of those who do not participate at the time. Revisions to the LCR should include options for risk management to occupants of those properties with remaining, partial lead service lines, e.g. ad ditional sampling, filters, dielectrics to reduce the risk of galvanic corrosion, plastic piping, aggressive premise flushing, etc.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

15 3.1.1. Update I nventories and I mprove A ccess to I nformation about Lead S ervice L ines

Updating and i mproving access to informat ion about the location of both full and partial lead service lines

is both essential to ensuring LSLs are replaced and important for successful, proactive outreach to

customers who are most likely to have a LSL.

The LCRWG recommends combining:

1) The p resumption that a service line put in place prior to the date when lead service lines were prohibited has lead ed materials unless the PWS has information to confirm that it not , with

2) Providing credit to a PWS toward its replacement goals for demonstrating that a service line presumed to include lead does not have lead ed materials.

This approach is intended to create incentives for prompt action to develop an accurate inventory of LSLs

and PLSLs in part by being overly conservative initially on the potential existence of LSLs , time to organize an effective replacement program, and an opportunity to take action to replace LSLs rather than devoting time and resources on plan ning documents that must be approved by the primacy agency.

The LCRWG recognizes that PWSs vary in the amount of information they have about the location of full and partial LSLs. EPA should take the impact on small and medium systems into account when developing the proposed rule

.

The LCRWG also recognizes that the curre nt definition of a lead service line exempts a service line that has a lead pigtail or gooseneck or other fitting but is otherwise not made of lead. We recommend that the LCR be revised to remove this exemption since a lead pipe, even if only a small port ion, poses a sufficiently similar risk as a full lead service line. Because utilities may not know where these portions are and may not be able to locate them without excavating, we recommend that the presumption described above not apply to lines where t he utilities do not have information or are unaware of their use. Finally, we recommend that these fittings be replaced when they are encountered during excavations and that the applicable operations and customer engagement requirements described in the n ext section apply.

In addition, the LCRWG recommends that a ll PWSs should establish a clear mechanism for customers to access information on LSL locations (at a minimum). Detailed public education recommendations for both lead and copper follow in separ ate section s . With respect to information about LSLs, PWSs should:

o Have outreach materials that indicate that property specific information is available

.

o Inform customers who may have LSLs about the risks of partial line replacement, who is responsible for paying for replacing the service line, and the legal basis of that determination.

o Provide information it has about LSLs to existing home owners and residents on request

.

o Provide information to realtors, home inspectors, and potential home buyers on request

o Communicate that this information is subject to disclaimer for accuracy based on information

available to the PWS

.

o Develop a system to track LSL replacement.

Where a service line serves mu ltiple dwellings or places such as schools or child care centers that have many children, EPA should establish a formula for giving an extra weight or numerical count to theseReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

.

3.1.2. Establish A ctive LSL Replacement P rograms

Proactive LSL replacement programs by PWSs and their customers are key to moving to a future in

which lead is not in contact with drinking water. To accomplish this, the LCRWG recommends replacing

the current regulations , in which LSL replacement is required only if a PWS has a lead AL exceedance

and after the PWS takes action to operate CCT , because t his has not resulted in the complete rep lacement of many LSLs across the country. 3

Instead, a revised LCR should include a requirement that all PWSs with lead service lines prepare and implement a LSL replacement program, along with a combination of changes to the regulatory approach

described in this report and supportive actions by other public and private agencies , customers and other

stakeholders. Taking this approach has the advantages of making replacement of LSLs something all systems do and of establish ing programs that are put in place in an organized and measured way.

Supportive a ctions include increased funding of federal lead risk reduction programs under the Department of Housing and Urban Development (HUD) to help fund customer

- owned portions of LSLs

and to consider federal tax deductions for this purpose. Additional ly, states should pass legislation requiring inspection, disclosure and/or replacement of LSLs on sale of property

, and when lines have been disturbed as part of a renovation . Details on these and other ideas are included in Section 4 of this

report

.

The LCRWG rec ommends that EPA include the following revisions to the LCR:

1. Goal: PWSs will work with their customers to implement full replace ment of all lead service

lines in their service areas according to the milestones outlined in Table 1. Revisions to the LCR

s hould maximize the likelihood of achieving this goal, consistent with the recommendations in

this section. EPA should urges PWSs to work with their customers to replace LSLs in their service areas more quickly, while recogniz ing that the recommended approach of replacing LSLs

in all PWSs with LSLs adds a new and potentially costly requirement for utilities and their

customers with LSLs who currently are not and may not ever be triggered into a LSLR program

under the current rule.

2. Interim Milestones: PWSs that identify LSLs in their inventory should be required to perform targeted outreach to customers on the inventory of LSLs and to work with them to replace LSLs according to a sequence of three

- year milestones, 4 beginning 36 months after the effective date of

a revised LCR . Miles tones would be set at a faster pace in earlier years and would recognize progress may be more difficult to achieve in later years with those LSLs that remain at that time.

Table 1 provide s an illustra tion of this concept. PWSs should be encouraged to contact a larger number of homeowners than needed for compliance, since some homeowners may fail to reply or may refuse to participate. If replacement goals are not met, the revised LCR should require th e PWS to take addition al actions intended to enhance interest in and incentives for customer participation in full LSL replacement. The details of this approach should be determined by EPA

with the intent of the LCRWG being that the PWS be given the flexibility to choose among

3 EPA estimates that there were approximately 10.5 million LSLs in 1988 before the promulgation of the LCR and approximately 7.3 million LSLs now.

4 Three years is a standard reporting timetable for dr inking water regulations.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

17 options that are appropriate for the size and type of ownership of the system and that the number of required efforts would increase over time if replacement goals are not met. EPA should seek

to add to the initial list of options suggested in Table 2 to ensure a robust menu for PWSs to choose from (again considering system size and type of ownership) to avoid a situation where a

PWS is forced into specific actions; and EPA should set the number of required efforts with consideration for the number and feasibility of choices provided.

3. Replacement Credit : The following actions can be counted toward the cumu lative replacement requirement:

• Full LSL replacement

• Replacement of lead pigtail where the pigtail is the only leaded material on the service line

• Confirmation that an LSL included in the initial inventory is not lead.

PLSLR will not be counted toward this requirement. Lack of response or refusal to participate by the customer also will not count toward replacement milestones.

4. Targeted Outreach : EPA should create a list of options in the rule of approved outreach methods for contacting customers with LSLs and inviting them to participate in the utility’s LSLR

program. Table 2 provides an initial list of options for such resident engagement, along with

additional system policies an d other actions if milestones aren’t met

. EPA also should provide guidance and/or templates for these options. For compliance purposes, the revised LCR should require that a PWS individually notify customers with known or possible LSLs describing the

ris ks of lead in drinking water, specifically inviting them to participate in the LSLR program, and clearly describing the terms of the program

, and how to follow up. If the customer does not respond or chooses not to participate, the PWS must follow up with another invitation at least every three years and always when the re is a new customer at that address until the full LSL is replaced

.

5. Control and Responsibility : The revised LCR should require PWSs to clearly state how the PWS defines ownership of LSLs, who has what financial responsibility for the replacement, what the legal basis is for that determination and any financial assistance programs that may be available

.

6. Planning and Financing Options: EPA should provide a template and guidance for planning LSL replacement programs, including reference to options to assist customers replace their portion of lead service lines. Small systems may wish to refer to a national information source, such as on e provided by EPA; large systems may wish to tailor such information to their circumstances. (See

section 4 for further detail.)

7. Operations and Customer Engagement: EPA also should provide guidance on PWS polic ies and procedures for how to engage cu stomers in full lead service line replacement and to inform them

on appropriate risk reduction measures. PWSs should ad opt templates provided in guidance by EPA or, for larger systems, their own standard operating procedures (SOPs) and make them

available to their customers and the primacy agency for :

a) planned capital projects by the PWS that would require :

o Prior notification (e.g., 45 days prior to planned main replacement or repair)

- Contact letter to affected households likely to have lead service lines, providing information about lead service lines, associated risk, risk reduction options, and full

lead service line replacement options.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

18 o Reminder of flushing post LSLR (e.g., 48 hours prior to actual field work affecting structure)

-- Door hanger (or alternative direct contact) with information on flushing and POU devices immediately after lead service lin e replacement.

b) emergency main and service line repairs by the PWS that would define how to manage potential dis turbance to LSLs safely:

o Direction to information on lead service lines, associated risk, risk reduction options,

and full

- lead service line rep lacement options.

o Door hanger (or alternative direct contact) with information on flushing and POU devices immediately after lead service line replacement.

c) flushing of service lines after lead service line replacement :

o F lush outside hose bib or similarly located spigot close to the meter

o Initial flush followed by house flush by homeowner or plumber using multiple taps to maximize water velocity

o Information on p roper use of filters when lead levels might be high

d) Requiring PWSs to inform other utilities (e.g. power, cable) whose work might affect water

service lines or water mains , both proactively and at “mark out” for specific projects, about how to manage potential disturbances safely and about information to provide residents of

affe cted homes about potential risks and risk mitigation measures. Those other utilities would have the responsibility to alert residents.

8. Community and NTNC water systems (schools, hospitals, churches, jails, etc.) who own the system and control the entire distribution system should replace LSL’s as soon as practical, at a timetable to be determined by EPA. This requirement would not apply to community systems where the majority of the connections are individual residential connections (such as mobile

home parks and HOA’s) where there may be complications due to property ownership of the

residence.

The LCRWG discussed and agreed that EPA guidance should encourage PWSs to make every effort to ensure that LSL replacement provides equal protection to low inc ome customers (or rental units with low income residents), people of color and others protected by civil rights law and policy. Environmental justice and civil rights considerations are particularly important in those jurisdictions where the PWS requires the property owner to pay a share of the costs of removing the LSL. Making environmental justice a priority can be achieved through creative financing programs for low

- income customers and setting priorities for which neighborhoods are target ed first for LSLR to ensure equal treatment of low income neighborhoods.

The LCRWG also discussed but did not agree that the definition of control as ownership should be changed in the revised LCR. In the current LCR , when a system exceeds the LAL, EPA requires water systems to replace only that portion of the LSL that it owns. This is based on EPA’s current interpretation of the term “control” in the definition of public water system as limited to ownership. Some members of the LCRWG urged that t he current definition of control as “ownership” should be replaced with a requirement that PWSs must replace the entire LSL, where they have the authority to “replace, repair, or maintain” the line or where they have other forms of authority over the LSL. However, the LCRWG al so recognized that some utilities are prevented by law from spending public funds on private property and that gaining physical access to private property poses significant legal issues when a property owner objects.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

19 Th e LCRWG does agree that the revise d LCR should require PWSs to inform customers about the scope of their responsibility with regard to LSL replacement and the legal basis for that decision.

3.1.3 LSL Compliance

3.1.3.a LSL Replacement Compliance

Recordkeeping:

• Inventory of LSLs

• Customer ref usals to participate in full LSL replacement

Reporting: At the end of each three year period, each P WS must provide to the primacy

agency:

• Certification of the outreach and other efforts implemented (see Table 2 for initial examples ) ;

• Report on the change in the number of LSL s removed from the inventory with better information;

• Report on the number of full LSL s replaced ; and

• Report on locations where the utility side LSL was replaced , but the homeowner did not replace the private portion

Violations :

- Failure to conduct required outreach;

- Failure to step up intensity of efforts if 3

- year LSL replacement target has not been met;

- Failure to provide on

- going outreach to new customers and to follow up (at least every 3 years) with customers at locations w ith full or partial LSL who do not respond or chose not to participate in the LSL replacement program;

- Outreach materials do not meet the content requirements of the rule

3.1.3.b Operations and Customer Engagement Compliance

P WS must maintain records of who was notified, when notice was given, and content of notice for each capital project. (for 7a and 7b)

Violations:

- Lack of timely notice to customer that LSL removal is scheduled

- Notice materials do not meet rule content requirements

P WS also must develop SOP, and maintain records that it was provided to all utilities conducting activities which may impact LSL (for 7d)

Violation:

• P WS has not developed an SOP (or adopted an SOP template available on the National Clearingh ouse) or not provided it to other utilities

3.2 Develop Stronger Public Education Requirements and Programs for Lead and LSLs

Given the public’s role in the shared responsibility nature of the LCR, n otifying and educating the public about lead in drinking wa ter is important for risk reduction

. Public education about the risks of lead in drinking water also is important regardless of whether LSLs are present, since lead can be present in otherReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

20 premise plumbing materials. Moreover, t argeted outreach and, possib ly, other efforts are a key to the success of LSL removal programs

. The current LCR does not adequately focus on creating on

- going opportunities to educate customers on the risks of LSLs or on opportunities to replace them, especially

when action is most l ikely, e.g. at the sale of a home.

The objectives of public education programs should include consumer understanding of: 1) the risks of lead in drinking water; 2) the likelihood that the water in one’s home may contain lead; 3) the LCR as a

“shared re sponsibility” rule; and 4) the availability of additional resources that consumers can use to better minimize their exposure to lead.

Although t he LCRWG was briefed on and has experience with public education requirements and practices, it does not includ e members whose specific area of expertise is consumer

- centered risk communication. Thus, the LCRWG generally recommends that public education programs for lead should move away from past practices of one

- way communication from “experts” to the “public” t oward newer concepts of risk communication that involve sustained

, multiple, two

- way channels of ongoing

communication and partnership with the public

. 5 EPA should consult with those with such expertise

about the outreach and communication recommendations in this report, and encourage and apply best practices in effective ways to communicate with the public

.

Communication in languages appropriate to the demographics of the community, in clear terms understandable by the public, and with engaging, reader

- friendly graphics, photos, and video all help achieve greater understanding. Outreach programs and material s can be improved by involving people with diverse, and consumer

- oriented expertise and perspectives, includ ing consumer

- centered risk communication experts, community members with extensive experience with lead in water including

individuals not necessari ly affiliated with an organization , lead/copper corrosion experts, grassroots public

- health workers, and staff of PWSs, state and federal regulatory agencies and public health agencies. This information can and should be conveyed in different ways and t hrough different communication channels, tailored to the specific circumstances.

Thus, with th e se and other considerations in mind, the LCRWG recommends that EPA , in consultation with the aforementioned stakeholders and drawing on principles of consumer

- centered risk

communication:

• Establish an easily accessible, national clearinghouse of information about lead in drinking water to serve the needs of the public and of public water systems (section 3.2 .1).

• Require information be sent to all new customers on the potential risks of lead in drinking water (section 3.2.2)

• Revise the current CCR language to address lead service lines and update the health statements (section 3.2

. 3 ).Add requirements for targeted outreach to customers with lead service lines (section 3.1.1 ).

21 • Strengthen requirements for public access to information about lead service lines, tap monitoring results, and other relevant information (section 3.2. 4 ).

• Expand the current requirements for outreach to caregivers/health care providers of vulnerable populations (section 3.2. 5 )

As part of EPA ’s consult ation with the aforementioned communication experts and stakeholders , the

LCRWG recommends that EPA include consul tation about methods that would increase public awareness of and motivation to learn about the effects of lead in drinking water and the benefits of removing these materials and/or taking regular precautions when cooking or drinking, regardless of whether LSLs are present or there has been a lead AL exceedance. Consistent with this advice, EPA also should take small systems into account and consider whether such methods should be included in guidance or in revisions

to the LCR.

3.2.1 National Lead in Drinking W ater Clearinghouse

The LCRWG recommends that EPA take the lead, working with other partners to e stablish a national,

accessible information clearinghouse . The LCRWG suggests that this information clearinghouse includ e a website , that the materials on the web site be accessible for distribution through the Safe Drinking Water Hotline for those who may not have internet access, and that EPA investigate and apply newer communication technologies and ideas for interactive or other innovative means of communic ation with the public about lead in drinking water (e.g. social media methods and outreach programs)

.

The clearinghouse should include information in multiple languages, in clear terms understandable by the public, and should include engaging, reader

- fr iendly graphics, photos, and video . EPA is encouraged to include the design of the clearinghouse in its consult ation with people with diverse, and consumer

oriented expertise and perspectives described above

.

Such a clearinghouse would be intended for use by the general public

, PWS ’s, public health agencies, and health professionals

. It should include:

• information and educational materials for the public that the public could access directly and that

PWSs could use to meet many of the public education requirements of the LCR.

• guidance and templates, particularly for small systems, on SOPs for compliance with the LCR (e.g. templates for communicating lead monitoring results to individual customers, template s for expla ining to customers how to obtain information on whether their service line could be lead, templates for standard operating procedures related to the LSL replacement program recommendations above, etc).

• Principles and guidelines for best practices in deve loping the content of the public education

materials.

• Case examples of how communities have been successful in lead inventory updates and removal programs, information about funding sources, model ordinances or other types of authorities

PWSs have to ena ble them to implement full LSL replacements, and contacts to other relevant agencies

.

Further, EPA should consider best practices in methods for achieving greater public awareness of the clearinghouse so that it reaches as many people as possible.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

• Clear and prominent statement that no level of lead in drinking water is safe for human consumption and that a short

- term exposure to a young child can result in permanent harm to

the bra in if the levels are high enough.

• Clear and distinct language on the health risks of consuming lead in drinking water

3.2.2 Outreach to New Customers

The LCRWG recommends that a revised LCR require P WSs to provide information to all 6 new customers in a letter or via other direct means on the potential risks of lead in drinking water.

The outreach materials should i nclude information about the potential for lead from plumbing materials to contaminate drinking water even when a P WS meets the LCR LAL

, to contaminate drinking water in homes with and without LSLs, and to pose chronic and acute health risks to vulnerable populations. The specific information to be covered in those mat erials could be included in the consultation with the diverse group of experts as described in the introduction to Section 3.2 above and in Section 4 below

. Although the LCRWG defers to such a group, it suggests that at a minimum the following topics be

covered:

1. Information about lead in drinking water (its sources, variable and erratic release, and wide range of lead concentrations)

2. Information about the health effects of lea d in drinking water (including chronic and acute health risks)

3. Information about the LCR’s shared responsibility regime

4. Actions the P WS is taking to minimize lead in drinking water

• P WSs with LSLs would mention their proactive LSL replacement program

5. Steps consumers can take to reduce exposure to lead in drinking water

• In addition to a list of actions like the ones mentioned in the current Rule, P WSs with LSLs would spell out how consumers in homes with a LSL can participate in their proactive LSL replacement program

6. Phone numbers and online links for additional information (including a link to EPA’s online National Clearinghouse)

The outreach to new customer s should be delivered within 30 days or with the first bill.

3.2.3 Revise the C urrent CCR L a nguage

The CCR is a necessary but not sufficient source of information for the public. It can provide general information, but is not designed to be frequent or detailed enough for all public education purposes.

All community water systems (CWSs) shoul d continue to include a statement about lead in their CCR. There may be circumstances (e.g. a subdivision built entirely after January 2014 when “lead

- free” requirements came into effect), where a CWS can demonstrate that there are no lead

- bearing materia ls in contact with drinking water

. EPA may want to consider allowing the primacy agency to waive this CCR language requirement if an entire CWS can meet this criterion.

6 EPA may wish to consider circumstances under which exceptions might be applicable.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

24 The LCRWG recommends that the CCR language should be strengthened to include:

• P ublic health statements updated to reflect current understandings that there is no safe level

of lead and a summary of the health effects , that this risk pertains to everyone, and that some individuals are particularly vulnerable ;

• A link to the national cl earinghouse should be added to the CCR for all CWSs ;

• R ecognition that a CWS’s compliance with federal regulations does not guarantee what level of lead (lower or higher) might be found at the tap in a particular home; and

• T he message that customers play an important role in protecting themselves from exposure to

lead.

In addition, the work group recommends that PWSs where full or partial lead service lines exist (or are presumed to exist until an inventory demonstrates otherwise) also add information about what a lead service line is and how to contact the utility for information about how to find out if you have one and why you should replace it.

Further, t he LCRWG recommends that the following redraft of the CCR be considered as a starting point

for inco rporating the elements listed above, to be reviewed by the diverse group of experts that the LCRWG suggests EPA consult

.

Important Information from EPA about Lead If lead is present in your drinking water, it elevated levels of can cause serious health problems, especially for pregnant women and young

children. Lead can affect children’s brains and developing nervous systems, causing reduced IQ, learning disabilities and behavioral problems. Lead is also harmful to adults.

Contact us for information about lead service lines, how to find out if you have one and why you should replace it

. [Last sentence for systems with
LSLs.]

When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. Protecting you against exposure to lead is a shared responsibility. Your water utility is required to minimize the corrosivity of the water. However, because every home is different, the amount of lead in your tap water may be lower or higher than the monitoring results for your public water system as a whole. You can take responsibility for identifying and removing lead materials within your home plumbing and taking steps to reduce your family’s risk

. If you have

3.2.4 Strengthen Requirements for Public Access to I nformation

The LC R WG supports the public’s right to know about the quality of their water and considered various options to increase the public’s access to data related to lead and copper.

Under the current rule, the PWS is only required to make publicly available through the Consume r Confidence Report (CCR) that the “90 th percentile value of the most recent round of sampling and the number of sampling site s exceeding the action level.” 40 CFR 141.153. In many jurisdictions, aReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

25 concerned consumer may be able to obtain or view a redacte d version of the complete sampling data set but this approach is time

- consuming and burdensome on the PWS (or the state) and the community. EPA receives only a summary of the sampling results.

As the LCRWG evaluated different approaches, we kept in min d EPA’s Office of Enforcement and Compliance Assurance (OECA) five principles for highly effective regulations and that OECA is working with regulatory programs to evaluate new and revised rules against these principles. Principle 4 calls for

rules to “ l e verage accountability and transparency by providing the government and the public with real

time access to quality information on regulated entities” emissions, discharges and key compliance activities and outcomes.” OECA identified two tools to accomplis h this:

• Electronic reporting to the government.

• Public accountability via websites, paper/electronic mailings, and other ways to provide the public and stakeholders (e.g., customers, ratepayers) with compliance information.

The LCRWG encourages EPA to use the S DW IS

- Prime data system 7 that is under development to meet the first provision of the above goal

. Electronic reporting from utilities to a centralized data system would allow the public to access data from the State or EPA in a coordinated manner and allow for consistent access to all water quality data, not just data for lead and copper.

Until such time as the new data system is in place, though, the LCRWG believes that water systems should increase the availability of data to the public. This w ould include:

• T he number of samples over the Household Action Level (described in Section 3.5 below) in the last monitoring period, the highest level found during the last monitoring period, the median

levels , and the most recent 90 th percentile level comp ared to the “ system action level ” (renamed

from the current action level )

.

• Requiring water systems to include WQP

- related information on their webpage, or in the CCR or some equally accessible manner (e.g., CCT treatment, approved WQP ranges, WQP results f rom the last monitoring period )

• Encouraging water systems to post additional information on their webpages such as:

o Public education materials (and link to National Clearinghouse)

.

o Sampling protocol s the water system provides to customers to use when coll ecting lead sample s and any variations from EPA recommendations.

o Individual sampling results (with appropriate privacy provisions such as address redaction)

.

o Inventory (such as a map) of confirmed and presumed lead service lines

.

Where a community has lea d service lines, EPA should requir e PWSs provide a public statement of lead service line ownership and the legal basis of said determination

. (See section 3.1.2, point 5 “Control and Responsibility.” )

7 SDWIS is a database for storage about drinking water systems. The federal version (SDWIS/FED) stores the information EPA needs to monitor approximately 156,000 public water systems. The state version (SDWIS/STATE) is a database designed to help states run their drinking water programs. SDWIS

26 3.2.5 Routine O utreach to C aregivers/ H ealth C are P roviders of V ulnerable P opulations

The LCRWG recommends that a revised LCR encourage P WSs to cooperate in locally appropriate public education programs targeted at caregivers and health providers of the populations most vulnerable to lead in drinking water (i.e., pregnant women , infants, young children, and children with elevated BLLs). The intent of such outreach is to raise awareness among caregivers and health providers about the health risks of lead in drinking water, easy steps to prevent exposure , and the availability of EPA’s online National Clearinghouse for further information. It is expected that public education messaging in service areas with LSLs will differ from public education messaging in service areas without such lines.

In conductin g outreach to caregivers and health care providers it is important that the message be provided by an organization or individual that carries credibility with those audiences. The LCRWG suggests the way to best ensure that caregivers and health providers hear and respond appropriately to information about lead and drinking water is for water suppliers to participate in joint communication efforts, lead by state health departments, state lead poisoning prevention agencies, and state drinking water primacy a gencies. This outreach should be targeted to individuals, organizations and facilities likely to be visited by the vulnerable populations of pregnant women, infants, and young children , such

as :

1. l ocal public health agencies;

2. public and private pre

- schools, schools;

3. Women Infants and Children (WIC) and Head Start programs;

4. public and private hospitals and medical clinics;

5. pediatricians, obstetricians

- gynecologists, and midwives;

6. family planning clinics;

7. local welfare agenc ies; or

8. licensed childcare centers.

1. The outreach efforts should make use of the information provided in the clearinghouse

Examples of communication vehicles that might be suggested in guidance materials include:

• Development and routine delivery of a jo int communication from the P WS (or a group of

P WSs) and the City/State to:

27 Th e LCRWG also recommends that EPA, informed by the advice of the diverse group of experts

described above and working with CDC, HHS and HUD

, develop guidance (and make it available through the National Clearinghouse) on how to develop and deliver effective communication efforts to caregivers and health care providers focusing on ways those individuals and groups can reach pregnant women, parents of infants and young children and those who care for them. The audience for those materials would be state primac y agencies, state or local health departments, and state or local lead poisoning prevention agencies, as well as P WSs.

To support P WSs in the development of feasible, locally appropriate, and successful public outreach programs targeting vulnerable groups on a routine basis, the LCRWG recommends the following: that the diverse group of experts EPA may convene for the development of consumer

- centered public education messaging and materials (see introduction to Section 3.2 ), also develop guidelines and best practices that

P WSs can use to create proactive risk communication programs. Echoing extant principles and understandings of effective risk communication, 8 we imagine such programs to involve robust

collaboration between P WSs, many of the local public hea lth agencies and organizations listed above, as well as local childhood lead poisoning prevention groups (State

- funded and grassroots), environmental health organizations, and key community leaders (e.g., advisory neighborhood commissioners).

Education of public health and health care providers on lead and water issues

The LCRWG had extensive discussions about the frustration that members of the group had that many in the public health community minimized the risk of lead exposure from drinking water, p laced a lower priority on actions to reduce that risk, and frequently provided incomplete or conflicting information to members of the public or patients. This made and continues to make the work of water professionals in motivating appropriate action by c ustomers more difficult. Those in the health sector are highly regarded, and viewed as knowledgeable about all health related topics. Customers will look to them for advice and to validate what they hear from their water provider. Efforts by water syste ms to reach out to their customers must be appropriately re

- enforced by those in the health sector if those efforts are to be

successful.

The LCRWG recommends that EPA, CDC, HHS and HUD conduct training and outreach to local health agencies, medical profe ssionals and local and state lead poisoning prevention agencies on:

Violations:

• Failure to make this information available to the public

3.3 Improve Corrosion Control

Corrosion Control Treatment (CCT) involves the addition of chemicals (e.g. orthophosphates or silicate)

to create a barrier between the pipes and the drinking water, or to modify drinking water chemistry (such as pH and hardness) to inhibit the potential for corrosion. The concept is to manage the treatment system to reduce corrosion (and, thus, the release of metals such as lead and copp er) from the distribution system and premise plumbing

.

Under the current LCR, PWSs serving more than 50,000 people were required to work with their primacy agency (typically the state) from 1994 to 1997 to designate and install optimal corrosion control treatment. Systems serving 50,000 people or less must opt imize corrosion control treatment only if theReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

29 results of lead and copper tap sample exceed the action levels. A PWS exceeds the lead AL if ten percent or more of the tap samples collected are greater than the 15 ppb action level.

In evaluating CCT c hoices, a PWS must consider list of assessment parameters ; and, as part of the approval of a PWS CCT plan, the state also approves a shorter list of process control parameters applicable to that system to demonstrate that the selected treatment is being pr operly operated over time. For purposes of this report, the term water quality parameters (WQPs) applies to the se latter process control measures . Recommendations concerning WQPs are included in Section 3.4.

Based on the experience with current LCR req uirements provided to this work group and shared by work group members , t he LCRWG has concluded the following:

• CCT remains an important component of the LCR , in that it is intended to achieve a water quality

that minimizes dissolution of lead and copper in water

.

• Effective CCT varies based on the specific conditions from system to system . Increased knowledge about CCT since promulgation of the current LCR , if applied today

, could lead to improvements in CCT in some systems

. Thus, PWS s and the ir prima cy agency should apply the most current science, tailored to the unique circumstances of each system , to the choice of treatment plan and its associated water quality parameters

. A variety of factors affect the dissolution of lead in water, including but not limited to pH and alkalinity. Factors other than the stability of designated WQPs can include, among others, the formation/dissolution of protective scales; the presence of manganese, iron, chlorides, sulfates, aluminum and other materials; and

temper ature. Variations in water quality also can occur within the distribution system. These water quality conditions vary among PWSs, which in turn affect the CCT choices a PWS must make in the context of other regulatory requirements.

• Lead also occurs in different forms in plumbing systems, from soluble to insoluble and particulate

in nature. S ources of lead vary from the very common leaded solder and brass fixtures/valves, to LSLs, and to less common lead

- lined iron pipe. CCT is more effective in reduci ng exposure to soluble lead than it is for particulate lead

, although CCT that contributes to the formation of certain scales may also provide benefits in reducing exposure to particulates. Thus, while very important, CCT is not the only lead control me chanism that a PWS must have in place. In other words, CCT should not be relied upon by itself to control lead in water. Rather, it should be one of a tool box of other required mechanisms depending on a PWS’s particular conditions and lead sources (e.g. LSLs, lead ed solder, leaded brass, etc.). These tools are described in other sections of this report and include: LSL replacement (as well as the replacement of other less common

sources of lead such as lead

- lined iron pipe), current and future use of l ead

- free materials, stronger public education including targeted public education to vulnerable populations (pregnant

women and families with infants and young children) , availability of certified POU filters, instructions on how to flush plumbing systems when lead could be disturbed, etc.

3.3.1 Corrosion Control Recommendations

T he LCRWG recommends that:

• EPA release a revised CCT guidance manual as soon as possible and update this manual every six

years , so that PWSs and primacy agencies can take advantage of improvements in the science ;

• EPA provide increased expert assistance on CCT to PWSs and primacy agencies ;

• The LCR continue to require re

- evaluation of CCT when a PWS makes a change in treatment or

source water;Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

30 • The LCR continue to re quire WQP monitoring to ensure that the CCT is achieving the treatment objectives and that EPA consider requiring such monitoring on a more frequent basis with additional guidance on process control methods ; and

• L arge systems review their existing CCT plan in light of current science in a newly revised guidance manual with their primacy agency to determine whether the WQPs reflect the best

available current science. The LCRWG suggests that this review be done every six years following EPA’s six year rule r eview cycle, and subject to there being sufficient science change that EPA updated the guidance manual. EPA should plan to review and refresh Agency guidance every 6 years, subject to significant improvement in the state of knowledge, to allow research to inform rule implementation. In addition, regularly revised guidance would help states and systems stay current with corrosion control science as they respond to problem situations, but more importantly help them anticipate challenges as new water sources and treatments are brought on line, or they contemplate further refinement to corrosion control. Small and medium sized systems should work with their primacy agency to determine whether updates to CCT guidance is applicable to them.

3.3.2 Corrosion Control C ompliance

PWS must maintain records that it reviewed new EPA guidance manuals and assessed whether and, if so, what changes to CCT are applicable, based on the current state of the

science

.

Violation s :

- Failure to notify and consult with primacy agency on re

- evaluating CCT if the PWS makes a change in treatment or source water

- Failure to review CCT when EPA updates the guidance manual (for large systems)

- Failure to act if state notifies them that they should assess CCT or make adjustments,

based on state r eview of guidance manual (for medium and small systems)

3.4 M odify M onitoring Requirements

Under the current LCR, a PWS i s required to conduct monitoring to assess the effectiveness of its

corrosion control treatment (CCT) and trigger additional actions to reduce exposure when necessary. Water systems must compare sampling results to an Action Level (AL). The AL for lead is 15 μg/L and the AL for copper is 1.3 mg/L. In the Lead and Copper Rule (LCR), water systems must pri oritize sample site locations (often residences) within the distribution system which are at a high

- risk of elevated lead and/or copper in the water

. Selection and use of these elevated lead and copper sites enables a smaller number of sample sites than r andom or geographic site selection procedures.

Implementation of th is approach over time has revealed numerous challenges. Recruitment of customers

to take in

- home samples can be difficult and costly . Customers are not professional samplers and, thus,

m ay implement the sampling protocols inconsistently. Research on sampling protocols also has shown that sampling results may vary, and not necessarily consistently, based on the configuration and length of lines from the water main to the sampling tap and whether the sample is a first draw or a subsequent sample intended to reflect water that had been in a LSL for some time.

The LCRWG recommends two types of on

- going monitoring: 1) a more robust WQP monitoring program to improve process controls for CCT

, and 2) voluntary customer initiated tap water sampling coupled with a more robust and targeted public education program to encourage sampling , in part to provide directReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

31 information to consumers that they can use to reduce potential exposures to lead from drinking water in their home and to provide ongoing information to the PWS to identify and correct unanticipated problems

.

The LCRWG also recommends that EPA establish criteria for a PWS to transition from the current rule

framework into the new rule framework. The LCRWG recommends that the transition includes a

condition that a PWS must comply with the requirements of the curren t LCR until the PWS has achieved three rounds of monitoring results under the lead AL using the current LCR requirements. Results from past rounds of monitoring can be used or new data will be required if prior data are above the AL. At that point, the P WS can define their CCT or WQPs for the new rule as that which was used to achieve this record. The existing lead AL should be redefined as a System Action Level in the new rule wherein it will be used when determining re

- optimization , e.g. for use during a review of a new source or treatment, if

the state determines that additional utility tap sampling is warranted

. In other words, i t will provide a baseline target for confirming CCT if lead sampling is chosen as one means by which to determine CCT.

PWSs must continue to demonstrate that they are maintaining the WQPs used to establish the transitions. All systems, regardless of their lead AL status, should be required to transition to the new LSL replacement program and public education program requiremen ts of the revised LCR as of the effective

date of the new rule.

3 .4.1 Water Quality Parameter Monitoring

As noted above , WQP monitoring is distinguished from the more extensive list of parameters that a water system would consider as it evaluates corrosion control technology choices

. WQP s for the purpose of this

section involve the on

- going process control monitoring that demon strates that the selected treatment is being properly operated over time.

The WQP program recommended below builds on what is in the current rule by recommending :

1) more frequent monitoring than currently required and monitoring that is representative of the distribution system (e.g. at points currently used for DBP monitoring or at a subset of points used

for TCR monitoring) to capture currently undetected variability;

2) continuing to tailor WQPs to the individual PWS CCT plan and asking EPA to review and consider adding to the list of WQPs referenced in the LCR, based on EPA’s anticipated revision to the CCT guidance manual;

3) that WQP monitoring be periodically revisited based on the advancing science as documented in research reports and disseminated thro ugh periodically revised EPA guidance manuals ; and

4) that a more rigorous data review process such as control charting and similar process control techniques be used to take advantage of the collected data to improve the consistency of operation , encourage fine

- tuning of processes, reduce variability of water quality within the distribution system and detect and manage excursions

.

In addition, th ese data should be reviewed whenever there is a change in source or treatment (see 4.3 above); and, w hen a system or state primacy agency sees significant changes in WQP data, it should initiate a “find and fix” process, looking for what changed and why, and requiring the PWS make any

needed adjust ments or correct ions

. This provides one type of reality check and cor rection not explicitly

in the current LCR.

In addition, the LCR WG recommend s that systems which are not currently practicing CCT under the LCR but have been under the lead action level by virtue of either naturally non

- aggressive source water or by virtue of other aspects of treatment in use

, be required to conduct a WQP monitoring program toReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- corrosive are continuing to be in plac e.

3 .4.2 Tap Sampling for Lead

The LCRWG also recommends that a voluntary customer

- initiated sampling program based on the more robust and targeted public education efforts being recommended elsewhere in this report be substituted

for the current LCR t ap sampling requirements

. .

The results of the voluntary tap sampling program will be used for three separate p urposes:

• informing and empowering individual households to take action to reduce risk,

• reporting to health officials when monitoring results exceed a “household action level” (see

section 3.5 ) and

• ongoing information to the utility to assess effectiveness of CCT.

Information for Households

Data from customer

- initiated sampling will be valuable in informing and empowering individual

households and thus provide greater customer service

. All data provided to customers would need to include appropriate information about the variability of lead levels, that a single sample does not represent all water quality, and that levels at a particular tap at a particular time might be higher or lower. The

transmittal sh ould also provide appropriate information about the risks of lead exposure, sensitive populations, and actions the consumer can take to minimize risk.

This type of sampling is currently discouraged by the current rule because water systems are often concerned that “complaint” or “customer “ samples would be included into the require d 90 th percentile calculation with potentia l mandatory response actions if it exceeded the action level. This resulted in system not offering sampling or having the samples be analyzed through a private lab (and therefore the data would not be available for any utility management or regulatory pur pose)

. Currently, PWSs are mandated to return to the same locations which

, while it may have value for other reasons , means that many other households do not get the opportunity to understand their lea d exposure. Voluntary c ustomer

initiated sampling can also capture data from multi

- family residences, which is not included in the mandatory LCR sampling in most cases. A new approach could achieve greater customer service and

more data to understand and manage lead corrosion.

Outreach to enc ourage customers to sample will likely involve many different customer contact opportunities including the CCR, outreach related to having a LSL, outreach related to construction

contracts, new customer contact, community meetings, other educational outrea ch efforts, and whenever a customer contacts the CWS for a water quality question or complaint.

Customers should be given the opportunity to determine the type of information they are interested in,

thus sh ould be offered a menu of sampling protocols

, e,g

. a random daytime sample to determine typical exposure levels, first draw to determine the effects of a brass faucet, or a timed or temperature determined sample from within a service line. The National Clearinghouse should include templates with instruc tions for each type of sample.

Information for Public Health Officials

Data from customer samples which exceeded the “household action level” recommended in section 3.5

, would be required to be forwarded to health officials. While LCR tap water results are currently provided to the collecting household, the LCR does not require any action for individual high samples, and there isReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

33 no mandate to refer to health authorities. While the LCR cannot guarantee actions by health departments,

t his recommendation provides direct health intervention in those cases where sampling indicates high lead

levels.

Information for Assessing the Effectiveness of CCT

The third use of the customer tap sampling data is to provide on

- going information to the utility of potential changes in the effectiveness of CCT

. Under the current rule, most systems are sampling for one

four

- month period every three years

. Any changes or variability in le a d levels at the tap during the other 32 months of that period are missed. Unde r this proposal, it is anticipated that there would be a more regular stream of data from more locations , provi di ng information which can be used to understand system performance. The data would be provided to the state primacy agency and presented as tim e series data to facilitate identifying any changes in the data over time. Small systems might report the data on something as simple as a spreadsheet chart, while larger systems might use more sophisticated analytical methods to understand and use the dat a.

Unexpected or unexplained changes in the tap sampling data can be used in a “find and fix” approach to identify and respond to potential problems. This could be system initiated or in response to periodic review of the system data by the primacy agen cy, such as during a sanitary survey. This provides a reality check on whether something unexpected is happening within the distribution system, even though

consistent treatment was maintained. The more robust (in both temporal and geographic distributio n) of the customer sample data set provides a more powerful check on treatment than the current episodic sampling does.

Specifically the LCRWG recommends that the revised rule require that:

• any customer sampling data be reported to the state on a routine basis and include which of the menu of sampling protocols referenced above was used ;

• data be provided as soon as possible and no later than within 30 days to the custome r and

, if over

the household action level

, to the health department ( as discussed above and in section 3.5 ) ;

• the PWS maintain the data set for analysis and review, taking type and location of each sample into consideration, to identify trends and changes in the data ;

• the data be available for public review as described in section 3.2.4 ;

• the PWS and the state review the data and trend analy sis during sanitary surveys;

• annually , at the discretion of the primacy agency, the PWS provide the primacy agency with a data summary report of the three most recent years of all tap sampling data, the specific details of which should be determined by EPA ;

• if the three most recent years of customer sampling data show that the 90th percentile (running

three

- year calculation) is above the System Action Level, then the PWS must analyze any changes or trend s in the data to evaluate whether they are based on system

- wide, local , or

household

- based conditions, and provide the report and analysis to the state for their review and determination if additional analysis, re

- evaluation of CCT, or other actions such as household

based actions (LSL removal, education about lead

- free faucets and flushing after non

- use of

water, etc

. ) are appropriate.

• if the system makes any source or treatment changes, the PWS and state should use the customer sampling data in the consultation, review and approval by the State currently required by the

LCR.

The LCRWG also recommends that EPA provide guidance to states and PWSs on additional forms and types of data analyses which can be conducted on sampling data to provide more det ailed understandingReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

34 of trends and to support system decision making on customer actions, treatment evaluations or development of system plans and priorities for LSL replacement programs.

It seems appropriate to include some sort of floor to the number o f customer samples. Some me mbers of the group suggested that systems should be required to collect no fewer samples in a three year period than they would under the current three

- year reduced monitoring requirement.

When a system changes its source or t reatment, and is required to consult with the state, the state primacy

agency also may choose to require additional one

- time monitoring to evaluate those changes if the degree of the change warrants.

Some members suggested that some small systems might w ant the opportunity to maintain the current home tap water monitoring program. The revised LCR should allow this, while not discouraging customer sampling.

3.4.3 Sample Invalidation Criteria

Under the existing regulation (141.86 (f)(1)), “The State may inval idate a lead or copper tap water sample

if at least one of the following conditions is met. (i) The laboratory establishes that improper sample analysis caused erroneous results. (ii) The State determines that the sample was taken from a site that did not meet the site selection

criteria of this section. (iii) The sample container was damaged in transit. (iv) There is substantial reason to believe that the sample was subject to ta mpering.”

These are all good and necessary reasons for invalidating a sample and should be retained, but because this list is limited, samples must be accepted that are obvious “outliers” and don’t represent the water that is normally consumed and should not be used as a basis for treatment changes or public education. This is especially true for small systems where the limited number of samples required means that a single, unusually high, value can cause the Action Level to be exceeded. This could lead to installation of expensive treatment when treatment is not needed or adequate corrosion control is already being provided. While probably not as frequent, non

- representative samples could also cause water systems to be below the action level when treatment changes really are needed. Good invalidation criteria can help states address both problems.

The purpose of the invalidation is to make sure that decisio ns are based on the most representative set of samples possible and to do so through a process that provides adequate information to make good invalidation decisions and assures documentation of the reasoning behind the invalidation.

The following is a proposal from states that will serve those two functions.

States believe that the essential criteria for invalidation are already well stated in the Revised LCR Monitoring and Reporting Guidance (EPA 816

- R

- 10

- 004, March 2010) or the October 2006

memorandum on Manageme nt of Aerators During Collection of Tap Samples to Comply with the Lead and Copper Rule

. The LCRWG recommends that EPA tak e the following into account when revising the proposed rule and expand the invalidation criteria accordingly :

• M ake sure the sample is taken at a tap that is used regularly, and not an abandoned or infrequently used tap.”

• “ If f irst

- draw samples are collected at single

- family residences , the sample must always be drawn

from the cold

- water kitchen tap or bathroom tap.”Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

35 • “ If f irst

- draw samples are collected from buildings other than single

- family homes , the sample must always be drawn from an interior tap from which water is typically taken for consump tion.”

• “ P ublic water systems should not recommend that customers remove or clean aerators prior to or during the collection of tap samples for lead.”

36 3.5 Establish a Household Action Level



### The current lead action level is based on the 90 th 

### percentile of the collected samples. Without a maximum limit, some users may be exposed to levels of lead in the drinking water that presents a potentially significant health threat, especially to children, without exceeding the action level. 9


### If the levels are high enough and state and local authorit ies do not act, EPA could determine that the levels pose “an imminent and substantial endangerment to the health of persons” pursuant to section 1431 of the Safe Drinking Water Act. (40 USC 300i)

3.5.1 Household Action Level Recommendations



### To avoid the possible need to invoke section 1431 of the SDWA, the LCRWG recommends that EPA establish in a revised rule a “household action level” and require the PWS to notify the local health department and state drinking water authority of sample results over that level. The requirement would be triggered by any sample results that the PWS receives from a user or from its own monitoring. However, the PWS would not be required to make the notification until it has investiga ted the sample in a timely manner to elimi nate sampling or assay errors.

The existing rule already requires the PWS to notify residents of the results of water system conducted lead sampling. We would anticipate that the PWS would alert the resident to possibility that the health department ma y be notified when the sample was taken or the resident provided the PWS with the sample results. While this notice may have the unintended consequence of discouraging some customers from testing, it is important for the customer to

make an informed choice

.

In response to the notification, the PWS and the health department would consider the situation and take action that they deem appropriate (e.g., testing children’s blood, recommending a filter, discussing lead service line replacement with the resident or landlord, advising grandparents about risk to visiting children, or continuing to monitor the situation). We anticipate that the health department be the lead agency, and that the rule would not prescribe actions other than

notice as the situations ar e too diverse and complicated for prescription actions. The LCRWG encourages EPA to work with the Centers for Disease Control and Prevention on recommended approaches and make this information available through the clearinghouse discussed in section

4.2.

This requirement would be somewhat similar to the regulatory approach taken by the Department of Housing and Urban Development which mandates that public housing authorities notify the local health department within five days when it receives information from any source

that a child of less than six years of age living in an assisted dwelling unit may have an environmental intervention blood lead level. (24 CFR 35.1225)

9 The LCRWG discussed the rela tionship between the household action level and the current lead AL (to be renamed the system action level) . These levels have two distinct purposes. The LCRWG assumed during its discussions that the household action level would be significantly greater than the system action leve l . It recognize d, therefore that, depending on what level is set, the household action level may have impacts on other recommendations in this

report.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

37 

### We recommend that EPA set the household action level based on the amount it would take for an infant to have a blood lead level greater than five micrograms per deciliter (μg/dL) based on consumption by an average, healthy infant of infant formula made wit h water. When a child’s blood lead level exceeds five μg/dL, the Centers for Disease Control and Prevention (CDC) recommends that laboratories and health care providers notify local and state health departments and that action be taken to identify and pre vent further exposure. 10

3.5.2 Household Action Level Compliance

If household sample exceeds the household action level, PWS must promptly notify the household and the local public health agency; certify that this has been done, and maintain records of having done so.

Violation s :

- Failure to report data no later than 30 days after the result was received

, to

 Household

 Local public health agency

- Failure to certify to state that data was reported to the household and to the local public health agency within 30 days

- Failure to maintain records of correspondence between P WS and the local public health

agency,

3.6 Es tablish Separate Monitoring Requirements for Copper

The current LCR does not deal effectively with copper. Generally speaking, the current rule focuses on the health benefits associated with lead risk reduction , with the result that the currently required in

- home sampling is often done in locations with old copper that has passivated. Thus, the possibility may be missed that a system’s water chemistry could result in copper releases. Further, the current rule does not require public education for copper, which can have broad benefits

.

The LCRWG has concluded that the regulatory approach should separate lead and copper risk management, refocusing attention to where there may be a problem with copper without increasing the burden on systems where there is not a problem. This can be achieved in a cost effective manner by targeting copper monitoring requirements to those PWSs where there may be exposures

. 11

Elevated exposures to copper generally result from new copper plumbing 12 where water chemistry is aggressive to copper. It is technically possible to identify water chemistries that are aggressive versus not aggressive to copper. Thus, the LCRWG recommends that the requirements for copper monitoring focus first on sampling f or basic finished water quality parameters such as pH

, alkalinity , and orthophosphate in a way that is representative of the distribution system to identify waters that are aggressive to copper. Systems that can demonstrate that their finished waters are not aggressive to copper or that their

11 The LCRWG recommends this approach, assuming EPA determines that the health benefits of regulating copper justify the costs. A full health risk assessment for copper was beyond the scope of the LCRWG’s charge, however; and, thus, EPA’s analysis of whether benefits justify the costs may have implications for these recommendations.

38 distribution systems contain no copper should have no further copper monitoring requirements

. This could be written into the rule, rather than require a monitoring “waiver.”

3.6.1 Copper Recommendations

F urther , the LCRWG recommends that the LCR be revised based on the following concepts :

1. Instead of basing action on the results of routine, in

- home copper sampling, actions should be based on the aggressiveness of the water to copper. Systems can determine if their water is aggressive to copper by doing WQP monitoring in the distribution sys tem. All PWSs should be assumed to have water that is aggressive to copper unless they demonstrate that it isn’t.

2. EPA should develop criteria to define water that is not aggressive to copper for the purpose of establishing whether a system falls into t hat category (or “bin”) for the purposes of the LCR. EPA should consider the accuracy and potential variability of pH and alkalinity monitoring as well as corrosivity to copper in establishing pH and alkalinity ranges. The criteria also should

include co nsideration of passivation time. Examples of bins (for verification by EPA) would be:

a. if alkalinity is < 35 pH must be > 7.0 ( no upper pH limit)

b. if alkalinity is 36 to 100, pH must be > 7.2

c. if alkalinity is 101 to 150 , pH must be > 7.5

d. if alkalinity i s 151

- 250 , pH must be > 8

If orthophosphate is used, examples of bins would be:

a. if alkalinity <150, PO4 must be >1 mg/L

b. if alkalinity is 150 to 200, PO4 must be > 2 mg/L

c. if alkalinity is 200 to 240, PO4 must be > 3 mg/L

d. i f alkalinity is greater than 240, PO4 must be > 3.3 mg/L

3. PWSs can choose one of several approaches to demonstrate that their water is not aggressive to

copper:

a. Conduct water quality parameter monitoring to assess whether their water meets the

definition established by EPA.

b. Conduct a one

- time evaluation with copper sampling at vulnerable houses (houses < 2 years old with new copper plumbing ) to demonstrate that water chemistry is non

aggressive (copper levels fall under the AL/SMCL) . EPA may want to consider:

i. Limited number of sample sites needed given copper chemistry

ii. Provision for sample invalidation based on site

- specific conditions such as biologically

- induced corrosion.

c. Conduct a pipe loop study to demonstrate the water chemistry is non

- aggressiv e

d. C hange water chemistry to within the range established for non

- aggressive water quality

4. PWSs with water classified as non

- aggressive to copper must continue to demonstrate that the

water is non

- aggressive. PWS’s can choose to:

a. M aintain those WQPs that d emonstrate it maintains non

- aggressive water under ( 2 )

above , orReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

39 b. Conduct copper sampling at vulnerable houses (houses < 2 years old with new copper plumbing ) to demonstrate that water chemistry is non

- aggressive (copper levels fall under the AL/SMCL)

PWSs that are not able to maintain their WQPs must implement a public education program

as described in the next section.

5. PWS’s with water classified as aggressive to copper must initiate and maintain a public education program . The public education program m ust either provide:

a. I nformation to all new homes (new construction or change of service) upon initiation of

new service

AND

b.

i. Information to newly renovated homes at time of renovation

OR

ii. Information to all customers on a routine basis

In addition, in guidance, EPA should encourage PWSs to n otify contractors, plumbing suppliers, and plumbers of copper corrosivity and to w ork with relevant officials and organizations to consider building and plumbing code changes that would prohibit copper piping in new construction if the corrosive water conditions cannot be eliminated . EPA also should provide guidance and/or templates, particularly for small systems, for public education messages and modes of delivery.

6. EPA should consider whether or under what circumstances CCT should be required for a PWS classified as aggressive to copper Not all systems with water aggressive to copper necessarily will have homes with new copper, so treatment might not be necessary or perhaps even advisable, particularly for small systems that can control plumbing materials used or for systems in

communi ties that modify their plumbing codes. Passivation time of copper varies considerably, and CCT may not be necessary or advisable when passivation time is short if interim actions to protect public health other than CCT are feasible. In determining when C CT should be required and any associated monitoring requirements, EPA also should take into consideration that a PWS may not have access to information about renovations where new copper has been installed and, even when such information is available, can’ t control whether the customer will participate in a monitoring program. Setting the correct level and establishing a regulatory approach that triggers CCT only when necessary will require a complex assessment and is beyond the scope of this workgroup

.

7. In the revised LCR, systems should continue to be required to notify the primacy agency if they are making any long

- term treatment change or addition of a new source. This section of the rule should be made clear that for copper, the system may be required to demonstrate that its finished

water continue s to be non

- aggressive to copper (per 4 above)

.

8. Additional information needs to be gathered on the current distribution of pH, alkalinity, and phosphate residual among systems nationally to fully understand t he implications of this approach.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

40 3.6.2 Copper Compliance

Violations :

- Failure to implement public education, for PWSs that have not demonstrated their water chemistry is not aggressive to copper.

- Failure to maintain a monitoring program representative of the distribution system that demonstrates the system has water chemistry not aggressive to copper.

- Failure to provide notice to and, if required, consultation with the primacy agency, when a PWS makes a significant change in source or treatment (as in the cur rent LCR).

- Failure to implement CCT or other risk reduction actions prior to CCT as determined by the primacy agency.

4 Complementary Actions Critical to the Success of the National Effort to Reduce Lead in Drinking Water

T he LCRWG urges EPA not only to promulgate a revised LCR, but also to play a leadership role in educating, motivating, and supporting the work of other agencies , where EPA does not have the authority

to act . The LTR LCR is very important. However, removing lead from drinking water sys tems and reducing exposure to lead from drinking water in the meantime will require renewed commitment, cooperation and effort by government at all levels and by the general public

.

Specific recommendations for action in addition to the LTR LCR include ( grouped generally by who might take such actions ) :

EPA Actions

• EPA working across all offices to take an integrated approach to action and education on lead from all sources (paint, air, site clean

– up, etc.), with proper emphasis on lead in drinking

wate r, especially in relation to the populations most vulnerable to this source ( pregnant women, infants and young children ) . For example, OGWDW should coordinate with EPA’s

lead

- based paint program so lead hazards are communicated consistently.

• Work with oth er federal agencies including HUD in terms of lead programs including but not limited to expanding federal funding from those programs to include lead service line replacement ; HUD/DOT in terms of efficiency in possible coordination of lead service line

re placement with road projects and other construction projects; and CDC in terms of childhood lead poisoning prevention, screening, and protection programs

• Enhanced cooperation with state, county, and local health departments to promote an integrated approach to childhood lead poisoning screening, prevention, and protection that emphasizes drinking water and its potential as a primary lead source (e.g. infants dependent

on reconstituted formula ).

• EPA ne eds to work with agencies at all levels of government to support financial assistance programs for LSL removal. Building costs into a PWS’s capital budget planning should also

be a consideration.

• EPA should include diverse perspectives in its stakeholder engagement programs, including affected consumers (who should not be required to be members of formal organizations), lead poisoning prevention/clean water advocates, EJ advocates, lead/copper corrosion experts, andReport of the Lead and Copper Working Group to the National D rinking Water Advisory Council

- Final

41 representatives from PWSs, States, and f ederal agencies with Healthy Homes and childhood lead poisoning prevention programs.

Other Federal Actions

• A federal tax deduction to support replacement of the customer portion of LSLs

.

• EPA should work with CDC and HHS to ensure that the standard protocol for investigation of any child with elevated blood lead levels or of a home with lead levels above the HAL

include determination of whether there is a lead service line.

• EPA should work with HHS and HUD to modify funding guidelines for the Healthy Homes and other federal funding programs to explicitly authorize and prioritize the use of those funds for lead service line removal programs targeting the privately owned portion of any lead service line. The current situation of having tens of thousands of dollars spent by a local Healthy Home or lead poisoning prevention program to remove lead paint, and leave behind a lead service line because of arbitrary f u nding guidelines is unacceptable.

State or Local Actions

• Local or state building and plumbing codes , including possibility of prohibiting copper plumbing where water is aggressive to copper

.

• State Actions to support customer lead service line replacement , e.g.

o State legislation requiring inspection or replacement on sale of home

o Disclosure requirem ents at sale of home

o Requirements for LSL removal as part of school and day care licensing

o Building code requirements for LSL removal upon substantial renovation (could be national action as well)

o Priority in DW SRF funding

, especially if increased funding is available . (Criteria states might wish to consider include : PWSs where there is a high incidence of elevated BLLs for children, a high percentage of homes with LSLs, a high percentage of low income families, the PWSs pr ior efforts to replace LSLs, etc ) 13

• States should consider including requirements for lead in drinking water in state child care licensing rules.

Public Water System Actions

• O ptions EPA may want to describe in guidance and PWSs could consider include but ar e not
limited to:

a. Rate design considerations:

i. Low rates for low volumes

ii. Household size

- based rates

13 Good examples of programs which facilitate and enable private action include a Massachusetts program which provides a state income tax credit for the replacement of failing private wastewater treatment systems (septic tanks and leaching fields) coupled with a requirement for inspection and compliance with stricter rules upon property transfer; and many lo cal housing rehabilitations programs funded by Federal Community Development Block Grants (CDBG) which provide low or no interest loans for health and safety related improvements, payable upon property transfer, often with loan sunsets where repayment is n ot required or the balance is reduced over a period of continued occupancy by an income

- eligible homeowner. A similar loan program could be authorized by EPA under the Drinking Water SRF program.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council

42 b. Non

- rate policies

i. Budget billing

ii. Fixture retrofits and plumbing assistance by the PWS

iii. Service line replacement and insurance programs not provided by PWS

iv. Direct assistance, emergency bill payment relationships

v. Fixture retrofits and plumbing assistance by NGO organizations providing affordable housing

vi. Subsidies including LSL / connection replacement costs associated with street, sidewalk, and other repairs n ot related to drinking water infrastructure

vii. On

- bill financing provided by the PWS

c. Funding guidance

i. EPA’s Financing for Environmental Compliance

– Water

ii. Tools for Financing Water Infrastructure

d. Funding sources beyond rate revenue:

i. EPA’s Drinking Water State Revolving Fund (DWSLF)

ii. EPA Targeted Grants to Reduce Childhood Lead Poisoning

iii. USDA’s Water and Environmental Programs, U.S. Department of Agriculture, Rural Development

iv. HUD’s Community Development Block Grant Program

– U.S. Department of Housing and Urban Development

v. HUD Healthy Homes Technical Studies

vi. HUD Office Healthy Homes and Lead Hazard Control Lead Hazard Reduction Demonstration Program

vii. HUD Health Homes Initiative Lead Elimination Action Program

viii. HUD Office of Healthy Homes and Lead Hazard Control Le ad Hazard Control Lead Technical Studies Grant Program

• PWSs should educate and encourage partnerships with healthcare providers and health departments even when levels are below the AL.

Research

• Additional technical review and/or additional study is needed on how to conduct household and

service line flushing to remove particulate lead

.

• Published, peer reviewed research explaining that water in plumbing systems with leaded

materials and LSLs can have sufficient levels of lead in the water to be a risk to those consuming the water. This paper is important to gaining support from the public health agencies and others and to placing water in context with other sources of lead.

• Considering that lead remains a complex issue and that research and informa tion gaps still exist, the EPA should establish a Research and Information Collection Partnership to encourage the filling of these gaps in knowledge. The RICP should be initiated once the EPA begins working on the revised rule and continue for three years or more into the promulgation of the revised rule.

• The EPA and other agencies, such as the Water Research Foundation, should conduct research (such as bench scale and limited system case studies) to confirm the bins selected to define aggressive waters fo r copper. The bins are based on theory and need some level of confirmation prior to promulgating an actual regulation. This work can be done within the timeframe of developing a final rule.Report of the Lead and Copper Working Group to the National D rinking Water Advisory Council
