June 1999 APPENDIX D SYSTEM BURDEN AND COST MODELS ! Reading the Revised Regulation and Training Staff on New Requirements ! Lead and Copper Tap Monitoring Models ! Water Quality Parameter Monitoring Models ! Source Water Monitoring Models ! Lead Service Line Monitoring Models ! Public Education Models ! System Reporting Models June 1999 D 1 READING THE REVISED REGULATION AND TRAINING STAFF ON NEW REQUIREMENTS By definition, only under the LCRMR will systems incur cost and burden related to reading the revised regulation and training staff on these rule modifications. Thus, the baseline for this set of cost and burden estimates is zero, and the estimates presented below represent both the revised and net costs associated with the rule. Costs and burden are assumed to only be incurred during the first year of implementation  1999. Further, each system is assumed to incur an average of 4 hours of burden for reading, and 4 hours for training. The 1999 estimates for both cost and burden are presented below in a side by side table.

In the baseline model ( i. e., represents the original LCR), systems are assigned to one of five possible monitoring scenarios that are dependent on whether or not the system: exceeds the action level during initial monitoring, is required to conduct a study, and continues to exceed after treatment. The five monitoring scenarios are:

° Scenario 1: Small & medium systems that are below the action level & and large ( b)( 3) systems. ° Scenario 2a: Small and medium systems that exceed the action level, are required to conduct a corrosion control study, and no longer exceed after the installation of corrosion control treatment ( CCT) ° Scenario 2b: Small and medium systems that exceed the action level, are not required to conduct a study, and no longer exceed after the installation of CCT. ° Scenario 3a: Systems that exceed the action level, are required to conduct a corrosion control study, and continue to exceed after the installation of CCT. ° Scenario 3b: Small and medium systems that exceed the action level, are not required to conduct a study and continue to exceed after the installation of CCT.

Note: Any exceedance is assumed to occur during the initial round of monitoring.

Under the baseline, the 171 large ( b)( 3) systems were not assumed to monitor beyond the initial monitoring that was required in 1992. Therefore, these 171 systems are not included in the baseline model. The remaining 564 systems are in Scenario 3a because these systems are required to conduct a study and can only proceed to reduced lead and copper tap monitoring if they meet optimal water quality parameters ( OWQPs) versus qualifying for reduced monitoring once they are below the action level for two consecutive 6 month monitoring periods ( i. e., Scenarios 2a and 2b).

The LCRMR Tap Water Monitoring Model contains three additional scenarios. Scenario 1R applies to small systems that have received a lead and copper monitoring waiver. Scenario 2aAR applies to medium and small systems that are required to conduct a study and qualify for accelerated reduced monitoring after the installation of treatment. Scenario 2bAR includes those medium and small systems that qualify for accelerated reduced monitoring after treatment installation, but which are not required to conduct a study. Scenario 3aAR applies to large systems that install treatment and qualify for accelerated reduced monitoring.

Both the baseline and LCRMR estimates assume that laboratory costs are $ 7.31 per tap sample analysis. The commercial fee of $ 30 was adjusted to eliminate the labor component to avoid double counting, as all analyses are assumed to be performed in house ( i. e., $ 30  $ 22.69). In addition, both models assume that a total of 3.5 hours of labor are required for collection and analysis of each sample ( includes both lead and copper). Burden and cost summaries for the baseline model, the LCRMR model, and the difference between the two are presented after the monitoring schedules. The differences in burden and costs between the two models are due to continued monitoring by ( b)( 3) systems, monitoring waivers, and accelerated reduced monitoring. The impact of allowing systems that are on reduced monitoring to collected samples during other than the summer months was calculated outside this model and is not included in the summaries. A collection burden savings of 5.5 hours per sample was assumed for each system that was impacted by this revision ( 110 NTNCWSs were assumed to be impacted June 1999 D 3 during 1999 2001.)

baseline and revised Water Quality Parameter Monitoring Schedules, for both Tap and Entry Point sampling present the total number of samples per year during 1999  2009 for each system for each of the possible monitoring scenarios. In the baseline model, systems are assigned to one of four possible monitoring scenarios that are dependent on whether or not the system: exceeds the action level during initial monitoring, is required to conduct a study, and continues to exceed after treatment. The four possible monitoring scenarios are:

° Scenario 1: Small and medium systems that are below the action level and large ( b)( 3) systems. ° Scenario 2: Small and medium systems that exceed the action level and no longer exceed after the installation CCT. ° Scenario 3a: Systems that exceed the action level, are required to conduct a corrosion control study, and continue to exceed after the installation of CCT. ° Scenario 3b: Small and medium systems that exceed the action level during initial monitoring, are not required to conduct a study, and continue to exceed after the installation of CCT.

Note: Any exceedance is assumed to occur during the initial round of monitoring.

Under the LCRMR model, large systems that qualify for accelerated reduced monitoring are included under a separate Scenario 3aAR. By 1999, only systems in Scenario 3a, 3a A, and 3b are assumed to be collecting water quality parameter ( WQP) samples. All systems are assumed to have treatment in place and small and medium systems that are below the action level ( i. e., Scenarios1 and 2) are not required to conduct WQP monitoring. Further, none of the 171 large ( b)( 3) systems were assumed to monitor beyond the initial WQP monitoring that was required in 1992.

An entry point and WQP tap monitoring schedule for Scenarios 3a, 3a A, and 3b are provided immediately following this introduction. Because the number of entry points varies by water source, a separate entry point monitoring schedule is provided for ground water and surface water systems.

Both the baseline and revised estimates assume that laboratory costs are $ 40 per tap WQP sample analysis, and $ 25 each for entry point sample analysis. This analytical cost assumes that all analyses are conducted in house. In addition, both models assume that a total of 2 hours of labor are required for analysis of each tap WQP sample. However, WQP collection burden is assumed to be applicable to only those systems that chlorinate only or apply no treatment ( i. e., 80% of ground water systems, based on treatment information in SDWIS) and is 0.5 hours per entry point. An additional burden of 0.5 hours is applied to all systems for entry point sample analysis. Burden and cost summaries for the baseline model, LCRMR model, and the difference between the two models are presented after the monitoring schedules. The difference in costs between the two models is due to accelerated reduced monitoring and the collection of entry point samples at representative entry points by medium and large ground water systems.

number of sampling events per year during 1999  2009 for each system for each of the possible monitoring schedules. In both the baseline and LCRMR models, systems are assigned to one of seven possible monitoring scenarios that are dependent on whether or not the system: exceeds an action level during initial monitoring, is required to conduct a corrosion control study, is required to install source water treatment, and continues to exceed after the treatment. The seven monitoring scenarios are:

° Scenario 1: Large ( b)( 3) systems. [ Note: Small and medium systems that are below the action level are not included in the model.] ° Scenario 2a: Systems that exceed the action level, are not required to install source water treatment ( SOWT), and continue to exceed after treatment ° Scenario 2b: Systems that exceed the action level, are not required to install SOWT, are required to conduct a study, and no longer exceed after treatment ° Scenario 2c: Small and medium systems that exceed the action level, are not required to install SOWT, are not required to conduct a study, and no longer exceed after treatment ° Scenario 3a: Systems that exceed the action level, are required to install SOWT, and continue to exceed after treatment ° Scenario 3b: Systems that exceed the action level, are required to install SOWT, are required to conduct a study, and no longer exceed after treatment ° Scenario 3c: Small and medium systems that exceed the action level, are required to install SOWT, are not required to conduct a study, and no longer exceed after treatment Note: Any exceedance is assumed to occur during the initial round of monitoring. All systems exceeding the action level are assumed to install corrosion control treatment.

For each of the scenarios in which the system no longer exceeds after treatment ( 2b, 2c, 3b, and 3c), the model assumes that by 1999 these systems would no longer be conducting source water monitoring. The source water monitoring schedules for the remaining three scenarios are provided immediately following this introduction. Because the number of entry points varies by water source, a separate monitoring schedule is provided for ground water and surface water systems.

Both the baseline and LCRMR estimates assume that: systems will composite samples, all analyses are conducted by the system, the analytical burden is 1 hour, and the non labor analytical cost for materials is $ 7.31 to conduct both lead and copper. The commercial fee of $ 30 was adjusted to eliminate the labor component to avoid double counting of labor ( i. e., $ 30  $ 22.69). No collection burden is estimated because by 1999 all systems are assumed to be monitoring at least annually and that lead and copper source water samples are collected with other inorganic chemicals, such as nitrate. In addition, sample collection for large, medium, small is assumed to follow the standardized monitoring framework under the Phase II/ V rules and scheduling for monitoring is assumed to be based on system size. States are assumed to require different size systems to monitor during different years of the compliance period or cycle to better balance laboratory workload. Large systems are assumed to monitor in the first year of the compliance period or cycle, medium systems in the second year of the compliance period or fifth year of the compliance cycle, and small systems in the last year of the compliance period or cycle. June 1999 D 23 Burden and cost summaries for the baseline model, the LCRMR model, and the difference between the two are presented after the monitoring schedules. The differences in burden and costs between the two models are due to the LCRMR provision that allows systems with low source water lead and copper levels that exceed the action level to reduce the frequency with which they collect source water samples.

Monitoring Schedules, present the total number of samples per year during 1999  2009 for each system for each of the possible lead service line monitoring schedules. LSL monitoring only applies to community water systems ( CWSs), thus the schedules and costs do not include non transient non community water systems ( NTNCWSs). Under both the baseline and LCRMR models, systems are assumed to conduct two types of LSL monitoring: 1) Monitoring to determine if a line needs to be replaced and 2) Monitoring required after a line has been partially replaced. Within these two categories of monitoring, medium and small systems are divided into those required to conduct a corrosion control study and those for which no study is required; large systems are placed in the required to conduct a study category. Systems that conduct a study are assumed to begin LSL replacement 1 year ( for small systems) to 18 months later ( for medium systems) than those systems that are not required to perform a study.

Both the baseline and revised estimates assume that laboratory costs are $ 3.65 per lead sample. The commercial fee of $ 15 was adjusted to eliminate the labor component to avoid double counting, as all analyses are assumed to be performed in house ( i. e., $ 15  $ 11.35). In addition, both models assume that a total of 2.5 hours of system labor for collection and analysis related to each LSL sample.

The models also include burdens and costs associated with partial lead service line notification requirements. The baseline model assumes that 15 minutes is needed per household to offer to collect the sample/ inform people of the sample results. For the LCRMR model, the same burden assumptions are applied to small and medium systems to fulfill the pre and post notification requirements, but large systems are assumed to require 0.5 hours per household. Both models also include a mailing cost of $ 0.33 per notification.

Burden and cost summaries for the baseline model, the LCRMR model, and the difference between the two are presented after the monitoring schedules. The differences in burden and costs between the two models are due primarily to the collection of post replacement samples at each line under the LCRMR instead of at each home, as is assumed under the baseline model. This burden and cost savings is offset slightly by the more extensive partial lead service line notification requirements under the LCRMR.

burden and costs for delivering public education. Those burdens and costs for reporting compliance to the State are included under the System Reporting Model. By 1999, only those systems that continue to exceed after treatment are assumed to be delivering public education.

The delivery requirements for CWSs are different than those for NTNCWSs and burden and cost estimates have been calculated separately for these systems. The revisions to the public education requirements for NTNCWSs are not assumed to have a quantifiable impact and therefore, the burden and costs for these systems are the same under the baseline and LCRMR models. CWSs serving 3,300 and fewer people have a lower cost and burden in the LCRMR model because they are assumed to no longer deliver ( PSAs) or newspaper notifications.

Five burden and cost tables follow this narrative. The first four tables show in detail how the annual public education burdens and costs were derived for CWSs and NTNCWSs ( all burdens and costs are the same each year). First, the burden and cost to CWSs to mail inserts and pamphlets are presented in one table that applies to both to the baseline and LCRMR models. Next are two separate baseline and LCRMR tables that contain the CWS burden and cost for providing PSAs and newspaper notification. The fourth table includes the burden and costs for NTNCWSs and applies to both the baseline and LCRMR models. The final table contains the total burden and cost for the two models and the difference.

Of these, 25% are assumed to continue to exceed.

2. The number of households receiving inserts are assumed to equal the average population served for a given size category divided by 2.4 ( 1990 Census figure for the average number of people per household).

3. For systems serving > 3,300 people, the number of pamphlets and brochures was derived by assuming 58.1 doctors and 31 schools for every 100,000 people. This estimate is considered to be conservative enough to cover other facilities and organizations that are likely to provide services to pregnant women and children. For systems serving 3,300 or fewer people, the number of pamphlets and brochures was estimated at 5.

4. CWSs will buy material already printed ( 1991 RIA assumption). The cost per piece is taken from the AWWA 1998 bookstore catalog.

5. The cost to mail public education materials is 33 cents, the first class rate for 1999. It is assumed that 50% of systems will mail public education materials separately, and 50% will mail materials with their water bills.

6. 50% of systems are assumed to mail materials with the water bill, and the burden per system is assumed to be 3.75 hours for systems serving 500 or fewer, 6.35 hours for systems serving 501 3,300, and 15 hours for systems serving over 3,300. The burden per system associated with mailings separately for 50% of systems is June 1999 D 39 assumed to be 15 hours for systems serving 500 or fewer, 25 hours for systems serving 501 3,300, and 60 hours for systems serving over 3,300.

The reporting models correspond to the schedules developed for each monitoring model and the public education models. In addition, the reporting models assume that some of the reporting requirements under the LCR and LCRMR will have occurred prior to 1999 and thus, are not included in the burden and costs summaries. These requirements are: optimal corrosion control treatment recommendation, corrosion control study submission, certification that corrosion control treatment has been installed, and certification that source water treatment has been installed.

The per event system burden varies for each reporting requirement. The burden per reporting requirement is derived by multiplying the number of events by the per unit burden. The cost per reporting requirement is estimated by multiplying the system labor rate of $ 14.29 for systems serving 3,300 or fewer people or $ 16.69 for systems serving more than 3,300 people by the burden. In addition, for both reporting models, a postage cost of $ 0.33 is applied to the reporting of: lead and copper monitoring data, WQP monitoring data, source water monitoring results, public education compliance letter, and the annual lead service line letter. Additional categories that require separate postage in the LCRMR model are: monitoring waiver application; demonstration of representative entry points for WQPs, and partial lead service line replacement monitoring results/ demonstration of compliance with notification requirements. No mailing costs are assigned to changes in monitoring location, sample site justification or certifications, request for reduced monitoring, or changes in treatment/ addition of a new source. This information is assumed to be submitted with the lead and copper monitoring data.

Burden and cost summaries for the baseline model, LCRMR model, and the difference between the two models are presented after the number of events tables. The activity in the LCRMR model, entitled, " Calculation of 90th Percentile Levels and Reporting of Lead and Copper Data" is comprised of four provisions: the calculation of the 90th percentile levels by the State for some systems, continued lead and copper tap monitoring by ( b)( 3) systems, and the submission of fewer monitoring results due to accelerated reduced lead and copper monitoring and monitoring waivers.

SUPPLEMENTARY INFORMATION:

I. Additional Information About the Proposed Settlement

    Petitioner raised issues concerning the December 4, 2006, Federal
Register notice entitled ``Recent Posting to the Applicability
Determination Index (ADI) of Agency Applicability Determinations,
Alternative Monitoring Decisions, and Regulatory Interpretations
Pertaining to Standards of Performance for New Stationary Sources and
National Emission Standards for Hazardous Air Pollutants, and the
Stratospheric Protection Program,'' 71 FR 70383 (December 4, 2006). EPA
maintains a computerized database, known as the Applicability
Determination Index (``ADI''), which is a compilation of applicability
determinations, alternative monitoring decisions, and regulatory
interpretations pertaining to standards of performance for new
stationary sources, national emission standards for hazardous air
pollutants, and the stratospheric protection program. From time to
time, EPA publishes in the Federal Register notices of recent postings
to the ADI (``ADI Posting Notices''), similar to the notice at issue in
this petition for review.
    The settlement agreement provides that in the first ADI Posting
Notice signed after this settlement agreement is final and effective,
EPA will not use the expressions ``broadly termed applicability
determinations,'' ``broadly termed alternative monitoring decisions,''
or ``broadly termed regulatory interpretations,'' but will instead use
the following expressions, as needed: ``commonly referred to as
applicability determinations,'' ``commonly referred to as alternative
monitoring decisions,'' and ``commonly referred to as regulatory
interpretations.'' In addition, EPA will include the following
language: ``This notice does not change the status of any document with
respect to whether it is `of nationwide scope and effect' for purposes
of section 307(b)(1) of the Clean Air Act. For example, this notice
does not make an applicability determination for a particular source
into a nationwide rule. Neither does it purport to make any document
that was previously non-binding into a binding document.'' The
settlement agreement further states that no later than 30 days after
the date the agreement becomes final, EPA will provide a new search
capability for users of the ADI, such that users have the option of
performing a search limited to the documents contained in a single ADI
Posting Notice. If EPA complies with the terms of the settlement
agreement, Petitioner shall file for dismissal of the petition for
review with prejudice in accordance with Rule 42(b) of the Federal
Rules of Appellate Procedures.
    For a period of thirty (30) days following the date of publication
of this notice, the Agency will receive written comments relating to
the proposed settlement agreement from persons who were not named as
parties or intervenors to the litigation in question. EPA or the
Department of Justice may withdraw or withhold consent to the proposed
settlement agreement if the comments disclose facts or considerations
that indicate that such consent is inappropriate, improper, inadequate,
or inconsistent with the requirements of the Act. Unless EPA or the
Department of Justice determines, based on any comment which may be
submitted, that consent to the settlement agreement should be
withdrawn, the terms of the agreement will be affirmed.

II. Additional Information About Commenting on the Proposed Settlement
Agreement

A. How Can I Get A Copy of the Settlement Agreement?

    Direct your comments to the official public docket for this action
under Docket ID No. EPA-HQ-OGC-2008-0471 which contains a copy of the
settlement agreement. The official public docket is available for
public viewing at the Office of Environmental Information (OEI) Docket
in the EPA Docket Center, EPA West, Room 3334, 1301 Constitution Ave.,
NW., Washington, DC. The EPA Docket Center Public Reading Room is open
from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal
holidays. The telephone number for the Public Reading Room is (202)
566-1744, and the telephone number for the OEI Docket is (202) 566-
1752.
    An electronic version of the public docket is available through
http://www.regulations.gov. You may use http://www.regulations.gov to
view the settlement agreement, submit or view public comments, access
the index listing of the contents of the official public docket, and
access those documents in the public docket that are available
electronically. Once in the system, select ``search,'' then key in the
appropriate docket identification number.
    It is important to note that EPA's policy is that public comments,
whether submitted electronically or on paper, will be made available
for public viewing online at http://www.regulations.gov without change,
unless the comment contains copyrighted material, CBI, or other
information whose disclosure is restricted by statute. Information
claimed as CBI and other information whose disclosure is restricted by
statute are not included in the official public docket or in the
electronic public docket. EPA's policy is that copyrighted material,
including copyrighted material contained in a public comment, will not
be placed in EPA's electronic public docket but will be available only
in printed, paper form in the official public docket. Although not all
docket materials may be available electronically, you may still access
any of the publicly available docket materials through the EPA Docket
Center.

B. How and To Whom Do I Submit Comments?

    You may submit comments as provided in the ADDRESSES section.
Please ensure that your comments are submitted within the specified
comment period. Comments received after the close of the comment period
will be marked ``late.'' EPA is not required to consider these late
comments.
    If you submit an electronic comment, EPA recommends that you
include your name, mailing address, and an e-mail address or other
contact information in the body of your comment and with any disk or
CD-ROM you submit. This ensures that you can be identified as the
submitter of the comment and allows EPA to contact you in case EPA
cannot read your comment due to technical difficulties or needs further
information on the substance of your comment. Any identifying or
contact information provided in the body of a comment will be included
as part of the comment that is placed in the official public docket,

and made available in EPA's electronic public docket. If EPA cannot
read your comment due to technical difficulties and cannot contact you
for clarification, EPA may not be able to consider your comment.
    Use of the  http://www.regulations.gov Web site to submit comments
to EPA electronically is EPA's preferred method for receiving comments.
The electronic public docket system is an ``anonymous access'' system,
which means EPA will not know your identity, e-mail address, or other
contact information unless you provide it in the body of your comment.
In contrast to EPA's electronic public docket, EPA's electronic mail
(e-mail) system is not an ``anonymous access'' system. If you send an
e-mail comment directly to the Docket without going through http://
www.regulations.gov, your e-mail address is automatically captured and
included as part of the comment that is placed in the official public
docket, and made available in EPA's electronic public docket.
