1 IDENTIFICATION OF THE INFORMATION COLLECTION 

1(a) Title and Number of the Information Collection 

 Title: Information Collection Request for the Proposed Revised Total Coliform Rule 

 OMB Control Number: 2040-AD94 

 EPA ICR Number: 1895.06 

Note: This Information Collection Request (ICR) covers only the first three years after rule promulgation. 

The description of reporting and recordkeeping burden required for the full rule implementation, which 

exceeds the 3-year period for this ICR, is provided for informational purposes only. The costs and burden 

associated with the 3-year period of this ICR is described in Section 6 while the costs and burden of the 

10-year full implementation period is provided in Appendix A.

 

1(b) Short Characterization 

The proposed Revised Total Coliform Rule (RTCR) requires information collection 

regarding the effectiveness of treatment, the integrity of the distribution system, and the possible 

presence of fecal contamination. All public water systems (PWSs) are included in this 

information collection. The proposed RTCR uses total coliforms as an indicator to start an 

evaluation process that, where necessary, will require the PWS to correct sanitary defects. Under 

the proposed RTCR, E. coli will remain a regulated contaminant with a maximum contaminant 

level goal (MCLG) of zero and a maximum contaminant level (MCL) based on the presence of 

total coliforms and/or E. coli. All fecal coliform provisions (including the MCLG and MCL) are 

removed in the proposed RTCR. The intent of the proposed RTCR is to better address the 1989 

Total Coliform Rule (TCR) objectives and enhance the multi-barrier approach to protecting 

public health, especially with respect to smaller ground water PWSs. 

A large portion of the data collection under the proposed RTCR will involve monitoring, 

assessments, corrective actions, and public notification. Under the proposed RTCR, PWSs would 

continue to monitor for total coliforms and E. coli in the distribution system. All PWSs that meet 

certain trigger conditions (either a Level 1 or Level 2 trigger) are required to complete a Level 1 

or Level 2 assessment and submit an assessment form to the state1

 within a specified time period. 

For corrective actions not completed within the specified time period, PWSs must submit to the 

state a timetable for completing the corrective actions. Additionally, PWSs would continue to be 

required to provide public notification for violations (the level of notification depends on the 

degree of public health implication of the violation). Some state activities under the proposed 

RTCR include review and revision of PWSs’ sample siting plans; review of PWSs’ sampling 

results; review of completed assessment forms; consultation and coordination with PWSs to 

determine the appropriate corrective action to be implemented; review of PWSs’ certification of 

public notification; and recordkeeping of PWSs’ submissions. 

 1

The term “state” in the context of this ICR refers to any state or other primacy agency that has oversight 

authority for drinking water programs. 
ICR for the Proposed RTCR June 2010

 2 

PWSs and states have monitoring, reporting, and recordkeeping requirements under the 

national primary drinking water regulations (NPDWRs) (see 40 CFR2

 141.402, 40 CFR 141.403, 

40 CFR 142.405, 40 CFR 142.14, 40 CFR 142.15). All affected PWSs shall maintain and report 

to the state information documenting compliance with the treatment and monitoring 

requirements under the NPDWRs. States shall maintain records essential for program 

implementation and oversight. These records, retained in the Safe Drinking Water Information 

System (SDWIS), allow the Environmental Protection Agency (EPA) to track PWS compliance 

with NPDWRs. 

Data collected under the Safe Drinking Water Act (SDWA) are used by EPA’s Office of 

Ground Water and Drinking Water (OGWDW), and other EPA programs such as Superfund and 

Resource Conservation and Recovery Act (RCRA). The data may also be used by the Farmers 

Home Administration, the Department of the Interior, the Department of Housing and Urban 

Development, the U.S. Army Corps of Engineers, White House Task forces, the Federal 

Emergency Management Agency, the Food and Drug Administration, public interest groups, and 

many private companies and individuals. 

This ICR presents the burden and costs of the proposed RTCR to PWSs and states during 

the first three years following rule promulgation. For this 3-year ICR period, the average annual 

net change respondent burden and cost to PWSs and states is estimated at 839,526 hours and 

$23,767,060. The annual net change burden and cost to PWSs is estimated at 747,848 hours and 

$20,171,639. The estimated net change annual state burden for this ICR is 91,678 hours, at an 

estimated annual net change cost of $3,595,421. All costs estimated are labor costs. There are no 

operation and maintenance (O&M) or capital costs for the 3-year period covered by this ICR. 

The net change burden and cost estimates are discussed in greater detail in Section 6 of this 

document. 

Beyond the first three years after rule promulgation (when PWSs and states need to 

comply with the rule), the burden and costs associated with complying with the rule for states 

and PWSs will be captured in the Microbial Rules ICR (for monitoring burden and costs) and the 

Public Water System Supervision (PWSS) ICR (for public notification reporting and 

recordkeeping burden and costs). Since there are ongoing reporting and recordkeeping 

requirements under the current TCR, Appendix A of this ICR shows the net change in the 

reporting and recordkeeping burden and costs to be incurred by PWSs under the proposed 

RTCR. Note that these calculations are for informational purposes only and are not part of this 

ICR. 

 

The total number of respondents for this ICR is 154,894; 154,837 respondents are PWSs 

and 57 respondents are states and territories. The average annual net change in the number of 

responses for PWSs is 103,225 and averages 2.0 responses per respondent annually. The average 

annual net change in the number of responses for states is 51,669 and averages 906.5 responses 

per respondent annually. 

 

 This ICR was prepared in accordance with the November 2005 version of EPA’s Guide 

to Writing Information Collection Requests Under the Paperwork Reduction Act (PRA) of 1995 

 2 Title 40 of the Code of Federal Regulations

(or “ICR Handbook”) prepared by EPA’s Office of Environmental Information, Office of 

Information Collection, Collection Strategies Division. The ICR Handbook provides the most 

current instructions for ICR preparation to ensure compliance with the 1995 PRA amendments 

and the Office of Management and Budget’s (OMB) implementing guidelines.

2 NEED FOR AND USE OF THE COLLECTION 

The following sections describe the need for this information collection and the legal 

authority under which this information will be collected. Section 4 contains a summary of the 

major recordkeeping and reporting requirements for the proposed RTCR. 

 

2(a) Need/Authority for the Collection 

The proposed RTCR achieves the objectives of the 1989 TCR more effectively and 

efficiently, taking into account the changes in regulatory framework for implementing the 

SDWA over the past 20 years and experience with the TCR since it was promulgated in 1989. 

The information collected under the proposed RTCR is required by EPA to carry out its 

monitoring and enforcement responsibilities under the SDWA. Without comprehensive, 

up-to-date information on drinking water contamination, EPA would not be able to meet the 

SDWA statutory requirements. 

Section 1401(1)(D) of the SDWA requires that an NPDWR 

contains criteria and procedures to assure a supply of drinking water which dependably 

complies with such maximum contaminant levels; including accepted methods for quality 

control and testing procedures to insure compliance with such levels and to insure 

proper operation and maintenance of the system... 

This section also authorizes EPA to require PWSs and laboratories to use EPA-approved 

methods and quality assurance criteria for collecting and analyzing water samples. 

Section 1445(a)(1)(A) of the SDWA requires that persons subject to the NPDWR 

requirements 

establish and maintain such records, make such reports, conduct such monitoring, and 

provide such information as the Administrator may reasonably require by regulation to 

assist the Administrator in establishing regulations under this subchapter, in determining 

whether such person has acted or is acting in compliance with this subchapter... 

 
ICR for the Proposed RTCR June 2010

 5 

2(b) Use/Users of the Data 

Once compliance with the RTCR begins, each PWS maintains PWS-level records on the 

analytical results of monitoring actions and corrective actions taken and of the reports or written 

communications with the state regarding violations, assessments, corrective actions, and public 

notification (see 40 CFR 141.31 and 141.33). PWSs will use the data collected from this ICR and 

from the Microbial Rules ICR and PWSS ICR, when the rules goes into compliance, to: 

 Determine system-specific needs 

 Evaluate the effectiveness of treatment 

 Determine the integrity of the distribution system 

 Signal the possible presence of fecal contamination 

 Correct significant deficiencies 

 Alert the public through notices in the mass media or water bills when PWSs are not in 

compliance with Federal and state regulations 

States are required to maintain records compiled from PWS respondents (40 CFR 

142.14). States can use these records to track PWS monitoring, compliance violations, and 

enforcement activities. States can also track schedules for PWSs trying to achieve compliance. 

States are required to report the number of violations to SDWIS, which will help them target 

PWSs for compliance and take the necessary remedial action. SDWIS is a Federal information 

system that allows EPA and the states to store and retrieve information over time. Trends in 

compliance data can be evaluated at the PWS level, at the state level, and at the national program 

level. Usually, these data are used by EPA for maintaining oversight of the drinking water 

program (including supporting the Six-Year Review of NPDWRs mandated by SDWA) and for 

supporting Federal enforcement actions in cases where states fail to enforce. 

The states and EPA have a number of critical questions to answer as part of their 

supervision of PWSs. Information and data collected from this ICR and from the Microbial 

Rules ICR and PWSS ICR can be used to answer these questions, some of which are listed 

below. 

At the PWS level: 

 Does a PWS have Level 1 or Level 2 triggers requiring Level 1 or Level 2 assessments? 

 Does the result of a Level 1 or a Level 2 assessment indicate the presence of (a) sanitary 

defect(s) that require(s) corrective actions? 

 

 For PWSs not in compliance, why are they not in compliance and how can compliance be 

achieved? 
ICR for the Proposed RTCR June 2010

 6 

 What is the threat to public health of a PWS that is not in compliance? 

At the national and state level: 

 What are the national and state compliance trends? 

 What changes in national policy or regulation may be needed to increase the national 

compliance rate? 

 Is noncompliance a function of location, size, or other identifiable variable? 

Requests for PWS data and related statistical analyses are frequent. Requests for SDWIS 

data are often received under the Freedom of Information Act (FOIA). Approximately 200 FOIA 

requests are received per year. EPA also maintains an Internet access point for SDWIS data at 

their “Envirofacts” Internet site.

3 NON-DUPLICATION, CONSULTATIONS, AND OTHER 

COLLECTION CRITERIA 

The following sections verify and affirm that this ICR satisfies the PRA requirements, 

meets the OMB data-collection guidelines, has public support, and does not duplicate another 

collection. 

 

3(a) Non-duplication 

EPA has searched the Federal Information Locator System (FILS) in an effort to ensure 

nonduplication of the data collection efforts. The information collected under the proposed 

RTCR is needed to determine a PWS’s risk of microbial contamination and to evaluate the 

PWS’s compliance. To the best of EPA’s knowledge, data required by this proposed rule are not 

available from any other source. 

 

3(b) Public Notice Required Prior to ICR Submission to OMB 

Since this ICR is part of a proposed rule, public notice is not required prior to its 

submission to OMB. Instead, a notice for public comment for the ICR is included in the 

preamble of the proposed RTCR. Based on public comment received on the proposed rule, 

modifications will be made to the rule and underlying analyses prior to promulgation of the final 

rule. Where appropriate, these modifications will also be reflected in this ICR. A full discussion 

of public comments on the proposed RTCR, as well as EPA’s responses, will be provided in a 

separate document which will be available in the public docket established for this rulemaking 

once the final rule is published. 

 

3(c) Consultations 

 EPA noticed its intent to revise the 1989 TCR in July 2003 (68 FR 42908, July 18, 2003). 

To support the revisions of the TCR, EPA held several outreach activities and consultations. One 

of these outreach activities is a technical workshop that EPA held in Washington, DC, from 

January 30 to February 1, 2007 to discuss available information on the current TCR and 

available information regarding risks in distribution systems. 

In June 2007, EPA established the Total Coliform Rule / Distribution System Advisory 

Committee in accordance with the provisions of the Federal Advisory Committee Act (FACA), 

to provide recommendations to EPA on revisions to the 1989 TCR and on what information 

about distribution systems is needed to better understand and address public health impacts from 

potential degradation of drinking water quality in distribution systems. The committee members 

agreed on and signed the Agreement in Principle (AIP) that contains the advisory committee’s 

recommendations on revisions to the TCR that will improve implementation while maintaining 

or improving public health protection and distribution system water quality. The provisions of 

the proposed RTCR are based on the AIP. 
ICR for the Proposed RTCR June 2010

 8 

EPA has also committed in the AIP to hold a stakeholder meeting no less than once per 

year to engage stakeholders in the development of the proposed RTCR. EPA held two 

stakeholder meetings, the first one in April 2009 and the second one in May 2010, to provide 

draft proposed regulation updates and an opportunity for stakeholders to provide feedback on the 

development of the proposed RTCR. 

 As mandated by SDWA, EPA also consulted with the Science Advisory Board, the 

National Drinking Water Advisory Council, and the Secretary of the US Department of Health 

and Human Services on the proposed RTCR. EPA also consulted with Tribal governments in 

accordance with Executive Order 13175: Consultation and Coordination with Tribal 

Governments. EPA also convened a Small Business Advocacy Review Panel (SBARP) to look at 

the impacts of the proposed RTCR on small entities. A more detailed discussion on this latter 

consultation can be found in Section 5(c) of this ICR. EPA considered the recommendations it 

got from these consultations in developing the proposed RTCR. 

 

3(d) Effects of Less Frequent Collection 

During the three-year period covered by this ICR, EPA requires no reporting and 

recordkeeping associated with complying with the proposed RTCR. 

For compliance with the proposed RTCR (which happens beyond the three years covered 

by this ICR) EPA has determined that the monitoring frequencies for total coliforms and E. coli 

required of PWSs under the proposed RTCR are appropriate since less frequent data collection 

may fail to identify, in a timely manner, significant contaminant concentrations that may threaten 

the health and safety of drinking water consumers. EPA has considered alternatives for a wide 

range of frequency and burden estimates for data collection. EPA has selected the approach that 

requires the least frequent collection possible while maintaining its public health protection 

objectives. 

3(e) General Guidelines 

 This ICR was prepared in accordance with the November 2005 ICR Handbook prepared 

by EPA’s Office of Environmental Information, Office of Information Collection, Collection 

Strategies Division. The ICR Handbook provides the most current instructions for ICR 

preparation to ensure compliance with the 1995 PRA amendments and OMB’s implementing 

guidelines. 

3(f) Confidentiality 

 No confidential information will be collected as a result of this ICR. 

3(g) Sensitive Questions 

 No information of a sensitive nature will be collected as a result of this ICR.

4 RESPONDENTS AND INFORMATION REQUESTED 

The following sections provide information on the respondents and the information they 

are requested to provide. 

4(a) Respondents/NAICS Codes 

 

Under the proposed RTCR, respondents to the monitoring, reporting, and recordkeeping 

requirements include the operators and owners of PWSs, which include noncommunity water 

systems (NCWSs). The North American Industry Classification System (NAICS) Code for 

investor-owned water systems is 22131; the Standard Industrial Classification (SIC) Code is 

4941. The NAICS Code for both publicly owned water systems and state agencies is 92411 and 

the SIC Code is 9511. State officials serve in a role of respondent when reporting compliance 

data to EPA. 

PWSs are defined as those systems that provide piped water for human consumption and 

have at least 15 service connections or regularly serve at least 25 people at least 60 days per year. 

A community water system (CWS) is a PWS that serves at least 15 connections used by 

year-round residents or regularly serves at least 25 year-round residents. NCWSs, by definition, 

are all other PWSs. NCWSs include transient systems and non-transient systems. Non-transient 

systems serve the same 25 people at least 6 months per year (40 CFR 141.2). 

4(b) Information Requested 

4(b)(i) Data Items

States 

 During the first three years after rule promulgation, states need not comply with the 

proposed RTCR since the compliance date is three years after promulgation. Therefore, EPA 

requires no reporting and recordkeeping from states with regards to RTCR compliance. EPA, 

however, expects states to prepare and submit their primacy applications during this period. In 

addition to the general requirements contained in 40 CFR 142.16, EPA requires a state’s primacy 

application to contain information specific to the RTCR. This information includes: 

 The baseline and reduced monitoring provisions of the proposed RTCR the state will 

adopt and how the state will implement those provisions; 

 Written descriptions of the following: 

o Frequency and process used to review and revise sample siting plans; 

o Criteria for reduced monitoring; 

o Process for implementing the new assessment and corrective action provisions of the 

proposed RTCR; 
ICR for the Proposed RTCR June 2010

 10 

o Criteria and process for invalidating routine or repeat samples; 

o Criteria and process for approval of individuals allowed to conduct Level 1 and Level 

2 assessments; 

o Procedure for performing special monitoring evaluations during sanitary surveys for 

ground water systems serving 1,000 persons or fewer to determine whether systems 

are on an appropriate monitoring schedule; 

o Process of identifying seasonal systems and determining their monitoring schedule 

and start-up procedures; 

o Additional criteria for reduced monitoring; and 

o Procedures for seasonal systems to start-up operations at the beginning of each 

system. 

The following are the reporting and recordkeeping requirements for states beyond the 

first three years after rule promulgation (when PWSs need to comply with the RTCR). The costs 

and burden determination to comply with these requirements are not included in this ICR. 

In addition to the reporting requirements specified in 40 CFR 142.15, the proposed 

RTCR requires states to report the following to EPA (see proposed RTCR §142.15(c)(3)). 

 A list of systems that the state is allowing to monitor under a reduced monitoring 

frequency. 

In addition to those already specified in 40 CFR 142.14, states are required to keep 

records of the following (see §142.14(a)(10)): 

 Any decision to waive or extend the 24-hour time limit for collecting samples following 

either a total coliform-positive routine sample, invalidation, or a high turbidity 

measurement; 

 Any decision to allow a system to waive the requirement for three routine samples the 

month following a total coliform-positive sample; 

 Any decision to invalidate a total coliform-positive sample; 

 Completed and approved Level 1 and/or Level 2 assessments, including reports from the 

system that corrective action has been completed; 

 Any decision to reduce the total coliform monitoring frequency for a community water 

system serving 1,000 persons or fewer to less than once per month; 

 Any decision to reduce the total coliform monitoring frequency for a noncommunity 

water system using only ground water and serving 1,000 persons or fewer to less than 

once per quarter; 
ICR for the Proposed RTCR June 2010

 11 

 Any decision to reduce the total coliform monitoring frequency for a noncommunity 

water system using only ground water and serving more than 1,000 persons during any 

month the system serves 1,000 persons or fewer; and 

 Any decision to allow a system to forgo E. coli testing of a total coliform-positive sample 

if that system assumes that the total coliform-positive sample is E. coli- positive. 

Public Water Systems

 During the first three years after rule promulgation, PWSs need not comply with the 

RTCR since the compliance date is three years after promulgation. Therefore, EPA requires no 

reporting and recordkeeping from PWSs with regards to RTCR compliance. EPA, however, 

expects that PWSs will start revising their sample siting plans as necessary so that they will be 

available for state review and revision when the systems have to comply with the rule. 

 The following are the reporting and recordkeeping requirements for PWSs beyond the 

first three years after rule promulgation (when PWSs need to comply with the RTCR). The costs 

and burden determination to comply with these requirements are not included in this ICR. 

 In addition to the reporting requirements specified in 40 CFR 141.31, PWSs are required 

by the proposed RTCR to report the following to the states (see §141.861(a)): 

 E. coli MCL violation by no later than the end of the next business day after it learns of 

the violation, and provide public notification; 

 E. coli-positive sample by no later than the end of the next business day after the PWS 

learns of the analytical result; 

 Treatment technique violation for total coliforms by no later than the end of the next 

business day after the PWS learns of the violation. The PWS must provide public 

notification; 

 Completion of each scheduled corrective action for corrections not completed by the time 

of submission of the assessment form; and 
ICR for the Proposed RTCR June 2010

 12 

 Monitoring violation within 10 days after the PWS discovers the violation. The PWS 

must provide public notification. 

In addition to the recordkeeping requirements for PWSs specified in 40 CFR 141.33, 

PWSs are required by the proposed RTCR to keep records of the following (see §141.861(b)): 

 Any assessment form, documentation of corrective actions completed as a result of 

assessments, or other available summary documentation of the sanitary defects and 

corrective actions taken for state review. 

 

4(b)(ii) Respondent Activities 

States

During the first three years after rule promulgation, the only activities that take place are 

state primacy application and start-up activities, which include: 

 Reading and understanding the rule; 

 Adopting the rule and developing state program that will support implementation of the 

rule; 

 Modifying data management system; 

 Training staff; and 

 Reviewing PWS sample siting plans and providing recommendations for revisions to 

PWSs. 

Beyond the first three years, when PWSs need to comply with the RTCR, EPA expects 

the states to be involved in the following incremental activities (note that these activities are not 

part of the cost and burden determination for this ICR). Figure 4.1 shows the schedule of 

information collection and other compliance activities under the proposed RTCR. 

 Tracking compliance; 

 Analyzing and reviewing PWS data; 

 Making determinations concerning PWS monitoring requirements; 

 Responding to PWSs with positive samples (for the calculations shown in Appendix A, 

note that the net change in burden and costs for states to review PWSs monitoring results 
ICR for the Proposed RTCR June 2010

 13 

is zero because the TCR methodology is calculated on a per PWS basis and the total 

number of PWSs is the same for modeling under the TCR and proposed RTCR); 

 Recordkeeping; 

 Reviewing completed assessment forms and consulting with the PWS about the 

assessment form; 

 Reviewing and coordinating with PWSs to determine the optimal corrective action to be 

implemented; and 

 Providing consultation, reviewing the public notification certification, and filing the 

report of the violation. 

Public Water Systems 

During the first three years after rule promulgation, EPA anticipates PWSs to perform 

start-up activities, which include: 

 Reading and understanding the rule; 

 Planning, and mobilization; and 

 Revising existing sampling plans to identify sampling locations and collection schedules 

that are representative of water throughout the distribution system. 

Beyond the first three years, when PWSs need to comply with the RTCR, EPA 

anticipates PWSs to be involved in the following incremental activities (note that these activities 

are not part of the cost and burden determination for this ICR). Figure 4.1 shows the schedule for 

information collection and other compliance activities under the proposed RTCR. 

 Conducting routine, additional routine, and repeat coliform monitoring.3

 

 Completing a Level 1 assessment if the PWS experiences a Level 1 trigger, and 

submitting a timetable to the state to identify sanitary defects detected, corrective actions 

completed, and a timetable for any corrective actions not already completed. 

 Completing a Level 2 assessment if the PWS experiences a Level 2 trigger, and 

submitting a timetable for any corrective actions not already completed. 

 3 For the calculations shown in Appendix A, note that the net change in reporting and recordkeeping burden 

and costs for PWSs to submit monitoring results to States is zero because the TCR methodology is calculated on a 

per PWS basis and the total number of PWSs is the same for modeling under the TCR and proposed RTCR.

 Correcting sanitary defects found through the performance of Level 1 or Level 2 

assessments.4 

 Developing and distributing Tier 1 public notices when E. coli MCL violations occur. 

 4 For the calculations shown in Appendix A, note that only the net change in the number of corrective 

actions performed under the proposed RTCR is accounted for. EPA estimates that additional corrective actions 

would be performed for only 10% of the assessments undertaken as a result of the proposed RTCR. EPA estimates 

that corrective actions found through Level 1 assessments would result in corrective actions that focus more on 

transient solutions than on permanent fixes to the PWS. Corrective actions taken as a result of Level 2 assessments 

are expected to find a higher proportion of structural/technical issues resulting in material fixes to the PWSs and 

distribution system.

5 INFORMATION COLLECTED -- AGENCY ACTIVITIES, 

COLLECTION METHODOLOGY, AND INFORMATION 

MANAGEMENT 

The following sections describe EPA activities related to analyzing, maintaining, and 

distributing the information collected. 

5(a) EPA Activities 

The EPA will be responsible for promulgating the RTCR once it has been finalized and 

overseeing its implementation. Implementation of monitoring requirements will rely extensively 

on state governments in those states that have assumed primacy under section 1413 of the 

SDWA and §142.16 of the proposed RTCR. The EPA will be involved in the following 

activities: 

 Developing the RTCR and guidance materials; 

 Reviewing and analyzing data submissions from the states; and 

 Processing and maintaining the SDWIS. 

These are all general activities that are covered under the PWSS Program ICR, and therefore, are 

not included in the EPA burden and costs estimates for this ICR. 

5(b) Collection Methodology and Management 

Upon compliance, states will send their records of PWSs’ violations and whether a PWS 

had a sanitary survey to SDWIS. EPA will modify SDWIS and data verification procedures to 

accommodate the new information from the proposed RTCR. 

EPA will check data quality by doing the following: 

 Developing standard operating procedures for each rule; 

 Editing the data submitted for content and required format in SDWIS; 

 Sending rejected data back to the states for error corrections; 

 Requiring states to resubmit corrected data; 

 Data verification audit of states based on data verification protocol established by EPA; 

and 

 Conducting a review of states annually for corrective actions. 
ICR for the Proposed RTCR June 2010

17

EPA plans to modify its existing data verification process to: 

 Include the number of PWSs with discrepancies; 

 Include onsite verification in states and PWSs, if necessary, every 2 to 3 years; 

 Train states on data verification procedures so they can conduct self-audits; 

 Include timeliness reviews; 

 Incorporate proposed RTCR-related activities into EPA Regional quarterly/annual 

reviews; and 

 Include a regional check with states within six months of the previous data verification. 

SDWIS runs on an IBM ES9000 12 way processor using mainframe edit programs (in 

JCL). EPA defines information requirements and states update the data in batch file mode in a 

pre-defined format. The public may access the violations data in SDWIS through the Internet at 

http://www.epa.gov/enviro/html/sdwis/sdwis_query.html. 

5(c) Small Entity Flexibility 

 

 In developing this ICR (and for the subsequent renewal of the Microbial Rules ICR and 

PWSS ICR), EPA considered the requirement of the Small Business Regulatory Enforcement 

Fairness Act (SBREFA) to minimize the burden of information collections on small entities. 

EPA considers small entities to be PWSs serving fewer than 10,000 people (63 FR 44524, 

August 19, 1998). 

The proposed RTCR will have the greatest impact on small PWSs. Under the Regulatory 

Flexibility Act (RFA), 5 U.S.C. 601 et seq., as amended by SBREFA, EPA generally is required 

to conduct a regulatory flexibility analysis that describes the impact of a regulatory action on 

small entities. To assess this impact, EPA conducted outreach to small entities and convened a 

Small Business Advocacy Review Panel (SBARP) in February 2008 to obtain advice and 

recommendations of representatives of the small entities that potentially would be subject to the 

proposed rule’s requirements. These recommendations are discussed below. 

5(c)(i) Small Business Advocacy Review Panel Recommendations 

 The Panel recommended to use total coliforms as a trigger for investigation and/or 

corrective action, to balance monitoring requirements and costs with risk, to further differentiate 

requirements with other related rules, and to consider reporting and recordkeeping costs in 

estimating burden. 

EPA considered the Panel’s recommendations in developing the proposed RTCR. The 

proposed RTCR eliminates the MCLG and MCL for total coliforms and instead uses total 

coliforms as an indicator of the potential pathway of contamination into the distribution system. 

PWSs that may be vulnerable to fecal contamination (as indicated by their monitoring results) 
ICR for the Proposed RTCR June 2010

18

are required to do an assessment and if necessary, appropriate corrective action. Other provisions 

of the proposed RTCR also result in reduced costs for many small PWSs and address the 

recommendations of the Panel mentioned previously. These provisions include: 

 Reduced routine monitoring for qualifying PWS serving 1,000 persons or fewer. 

 Reduced number of repeat samples required. 

 Reduced additional routine monitoring for PWS serving 4,100 or fewer people. 

 Reduced public notification requirements for all systems, including small systems. 

 Reductions in corrective actions over time as a result of enhanced system performance 

for all small systems. 

Furthermore, consistent with the Panel recommendation to evaluate which parameters are 

most appropriate for routine monitoring and as potential triggers for investigative and corrective 

actions, EPA is conducting a review of existing models for total coliform and E. coli analysis and 

is evaluating its Alternative Test Procedure protocol for approving new methods. EPA is also 

one of the founding members of a Research Information Collection Partnership that is 

considering research and information needs to evaluate potential indicators of distribution system 

contamination.

5(d) Collection Schedule 

The RTCR is scheduled to be promulgated in 2012, with monitoring beginning 3 years 

after promulgation. Figure 4.1 illustrates the information collection periods for compliance with 

the proposed RTCR over the first 10 years following rule promulgation.

6 ESTIMATING BURDEN AND COST OF COLLECTION 

The following sections discuss costs and burden for all information collection, 

recordkeeping, and reporting requirements for the proposed RTCR. 

6(a) Estimating Respondent Burden and Cost 

The following sections discuss the costs and burden faced by PWSs and states. Note that 

the majority of the monitoring, recordkeeping, and reporting burden occurs beyond the 3-year 

period of the ICR. Exhibits A.34 and A.37, located in Appendix A, include a ten-year time frame 

showing the burden and costs beyond the initial period covered by the ICR. This reflects the 

reality of rule implementation. Figure 6.1 presents a summary of estimated responses, burden, 

and costs for the 3-year window of the ICR.

Responses

6(a)(i) Burden and Cost to PWSs 

Information collection activities of PWSs required under the proposed RTCR will result 

in average annual net change national labor costs of $20.2 million and a corresponding annual 

net change burden of 747,848 person-hours as shown in Figure 6.1 and in Exhibits A.34 and 

A.37. The exhibits also include annual net change costs and burden up to 10 years following rule 

promulgation. 

The net change burden and costs are estimated for start-up activities, including reading 

the rule and training staff. The assumptions and methodologies used in deriving these estimates 

are discussed in the following section. 
ICR for the Proposed RTCR June 2010

20

6(a)(i)(a) Start-Up Activities 

Start-up activities are estimated at a one-time expense of $60.5 million (Exhibit A.37) 

and 2.2 million burden hours (Exhibits A.34). Start-up activities include reading the final rule to 

become familiar with the requirements and performing additional or transitional implementation 

activities such as training staff to on rule requirements. Additionally, all PWSs will incur onetime costs to revise existing sampling plans to identify sampling locations and collection 

schedules that are representative of water throughout the distribution system. 

For costing purposes, EPA estimates the labor needs and hourly labor rates of PWSs and 

states for two labor categories: managerial and technical. For PWSs, all analyses use labor rates 

presented in EPA’s document, Labor Costs for National Drinking Water Rules5. The technical 

and managerial wage rates vary with PWS size and include fringe benefits. To account for the 

general composition of staff at PWSs of smaller sizes (e.g., PWSs serving 3,300 or fewer), EPA 

uses only the technical rate. For PWSs serving more than 3,300 people, EPA uses a ratio of 80 

percent technical labor to 20 percent managerial labor to arrive at a labor cost, or weighted labor 

rate. A full description of the derivation of the labor rates used is provided in the Technology and 

Cost Document for the Proposed Revised Total Coliform Rule6

. The weighted labor rates ($2007) 

are shown in Exhibit A.1. 

 

6(a)(i)(b) Annual Activities 

In the tenth year of rule implementation, a net savings of $1.5 million (Exhibit A.37) and 

0.09 million burden hours (Exhibit A.34) is expected for annual PWS activity costs and burden, 

respectively. Included in this category are costs and burden to revise sampling plans; to conduct 

routine monitoring, additional routine monitoring, and repeat monitoring; to perform Level 1 and 

Level 2 assessments; to perform reporting and recordkeeping related to corrective actions; and to 

provide public notification. The net change cost and burden estimates for PWS annual activities 

are shown in Exhibits A.34 and A.37. These net change costs are for data collection and review 

and will occur outside of the three years covered by this ICR. 

6(a)(ii) Burden and Cost to States 

Total annual average net change state labor cost is $3.6 million, and the annual average 

net change burden is 91,678 hours for the three years covered by this ICR. 

6(a)(ii)(a) Start-Up Activities 

States are estimated to incur a one-time cost of $10.8 million (Exhibit A.37) and a onetime burden of 275,033 hours (Exhibit A.34). For states, the administrative and field engineer 

labor rates from the 2001 State Drinking Water Needs Analysis7

 are used in the proposed RTCR

Economic Analysis (EA) (as used in the Ground Water Rule (GWR) EA8). These rates include a 

60 percent overhead rate and were inflated to 2007$ using the Employee Cost Index (ECI). The 

state labor rates in 2007$ are $39.22 for an administrative state employee and $43.58 for a state 

field engineer. EPA assumes that the state field engineer would conduct annual site visits, and 

the administrative state employee would work with PWSs on all remaining aspects of the 

proposed RTCR. Because this separation between field engineer and administrative employee is 

used, the 80/20 weighting ratio between technical and managerial rates is not used to develop 

state costs. 

6(a)(ii)(b) Annual Activities 

In the tenth year after promulgation, a net savings of $0.54 million (Exhibit A.37) and 

0.01 million burden hours (Exhibit A.34) is expected annually for states to respond to positive 

sample results; to review completed assessment forms required to be filed by PWSs and consult 

with PWSs about their assessment form; to review and coordinate with PWSs to determine the 

appropriate corrective action to be implemented; and to provide consultation, review the public 

notification certification, and file the report of the violation. States must also submit information 

to SDWIS to assist both EPA and states in tracking PWS compliance (see Exhibits A.34 and 

A.37). 

State net change costs and burden for activities occurring outside of the 3-year ICR 

window are calculated in the same way as state net change start-up costs and burden. The 

administrative state employee labor rate is used for all rule activities under the proposed RTCR. 

6(b) Time Frame for Cost and Burden Estimates 

To provide a coherent understanding of how the burden for the rule will occur, the time 

frame for rule implementation is described below. 

In the first 3 years, EPA has estimated that states will adopt regulations for transitional 

implementation of the proposed RTCR and will apply for program primacy approval, and that 

states and PWSs will conduct transitional start-up activities for implementing the proposed 

RTCR, such as training, and data management system modifications. 

States are expected to incur one-time costs to review sampling plans and recommend any 

revisions to PWSs. PWSs are expected to revise sampling plans before monitoring begins. For 

modeling purposes costs are split between years 2 and 3 of the 25-year compliance period 

(monitoring is required starting in year 4). 

 Beginning in the fourth year following promulgation, PWSs would begin routine, 

additional routine, and repeat monitoring. Additionally, EPA expects that, beginning in the 

fourth year, PWSs would be required to correct sanitary defects found through the performance 

of Level 1 or Level 2 assessments. Reporting and recordkeeping burden from corrective actions 

resulting from Level 1 and Level 2 assessments would also begin in the fourth year following 

promulgation. For each corrective action performed, states would incur recordkeeping and 

 8

ICR for the Proposed RTCR June 2010

22

reporting burden to review and coordinate with PWSs. Revised public notification activities 

would also begin in the fourth year following promulgation. 

6(c) Estimating EPA Burden and Cost 

EPA’s costs include those incurred by both regional offices and headquarters to process, 

analyze, and maintain SDWIS data. These costs cannot be derived on a per rule basis but are 

presented as an overall program cost in the PWSS Program ICR. Headquarters personnel who 

design and administer SDWIS believe that the net additional cost of the regulations proposed 

here is not significantly greater than that of the PWSS Program. 

The EPA also performs the role attributed to states and territories, for those states and 

territories over which it has primacy. This cost is included as part of the total burden and cost for 

states. 

6(d) Respondent Universe 

There are a total of 154,837 PWSs and 57 states and territories considered for this ICR. 

6(e) Bottom Line Burden Hours and Costs 

This section provides a description of bottom line estimates for implementation of the 

proposed RTCR. The bottom line net change burden hours and costs for PWSs and states are the 

summaries of the hours and costs collectively incurred for all additional activities under the 

proposed RTCR in comparison to the current TCR. The first part of this section describes the 

estimated average annual net change costs and hourly burdens for respondents to the rule. The 

second part discusses the potential net change cost and burden to EPA. Figure 6.2 presents a 

summary of the average annual net change respondent burden over three years for PWSs and 

states. All additional exhibits relating to this ICR are in Appendix A.

6(e)(i) Bottom Line Burden and Cost Estimates for Respondents 

For this ICR, EPA estimates that PWSs will have an annual net change respondent 

burden of 747,848 hours and an annual net change respondent costs of $20.2 million. EPA 

estimates that states will have an annual net change respondent burden of 91,678 hours and a 
ICR for the Proposed RTCR June 2010

24

corresponding average annual net change respondent costs of $3.6 million. Therefore, the total 

average annual net change respondent burden is estimated to be 839,526 burden hours and the 

corresponding total average annual net change respondent labor costs are estimated to be $23.8 

million. See Figure 6.2. There are neither capital costs nor O&M costs during the 3-year ICR 

period. 

6(e)(ii) Bottom Line Estimate for EPA 

As mentioned previously in Section 6c, the costs and burden incurred by EPA to process, 

analyze, and maintain SDWIS are presented as part of the PWSS Program ICR. Additional costs 

that are likely to be incurred by EPA for tribes and the state of Wyoming are included in the tally 

for the costs and burden to states and territories because most costs are estimated on a per system 

basis and because the number of PWSs on tribal land or in Wyoming affected by various 

provisions of the rule is uncertain. 

6(f) Reasons for Change in Burden 

The primary goal of the proposed RTCR is to achieve the objectives of the 1989 TCR 

more effectively and efficiently, taking into account the changes in regulatory framework for 

implementing the SDWA over the past 20 years and experience with the TCR since it was 

promulgated in 1989. National burden estimates increase primarily because PWS requirements 

are being strengthened under the proposed RTCR. 

6(g) Burden Statement 

 The annual net change public reporting and recordkeeping burden for this collection of 

information is estimated to average 14.5 hours per PWS respondent per year and 1608.4 hours 

per state respondent per year for the 3-year ICR period.9

 

 Burden means the total time, effort, or financial resources expended by people to 

generate, maintain, retain, disclose, or provide information to or for a Federal Agency. This 

includes the time needed to review instructions; develop, acquire, install, and utilize technology, 

and PWSs for the purposes of collecting, validating, and verifying information, processing and 

maintaining information, and disclosing and providing information; adjust the existing ways to 

comply with any previously applicable instructions and requirements; train personnel to be able 

to respond to a collection of information; search data sources; complete and review the collection 

of information; and transmit or otherwise disclose the information. An agency may not conduct 

or sponsor, and a person is not required to respond to, a request for information collection unless 

it displays a currently valid OMB control number. The OMB control numbers for EPA’s 

regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15. 

To comment on EPA's need for this information, the accuracy of the provided burden 

estimates, and any suggested methods for minimizing respondent burden, including the use of 

automated collection techniques, EPA has established a public docket for this ICR under Docket 

ID Number EPA-HQ-OW-2008-0878, which is available for online viewing at 

 9

 The average burden hours were calculated by dividing the annual burden hours (from Figure 6.1) by the 

annual number of respondents (from Figure 6.2), e.g., for PWSs, 747,848 ÷51,612 =.14.5.
