Microbial Rules Renewal Information 

Collection Request 

Abstract: The Microbial Rules 

Renewal ICR examines public water 

system and primacy agency burden and 

costs for recordkeeping and reporting 

requirements in support of the microbial 

drinking water regulations. These 

recordkeeping and reporting 

requirements are mandatory for 

compliance per the Code of Federal 

Regulations (CFR) at 40 CFR parts 141 

and 142. The following microbial 

regulations are included: the Surface 

Water Treatment Rule (SWTR), the Total 

Coliform Rule (TCR), the Revised Total 

Coliform Rule (RTCR), the Interim 

Enhanced Surface Water Treatment Rule 

(IESWTR), the Filter Backwash 

Recycling Rule (FBRR), the Long Term 

1 Enhanced Surface Water Treatment 

Rule (LT1ESWTR), the Long Term 2 

Enhanced Surface Water Treatment Rule 

(LT2ESWTR), the Ground Water Rule 

(GWR) and the Aircraft Drinking Water 

Rule (ADWR). Future microbial-related 

rulemakings will be added to this 

consolidated ICR after the regulations 

are promulgated and the initial, rulespecific, ICRs are due to expire. 

Form Numbers: None. 

Respondents/affected entities: Entities 

potentially affected by this action are 

new and existing public water systems 

and primacy agencies. 

Respondent’s obligation to respond: 

Mandatory for compliance with 40 CFR 

parts 141 and 142. 

Estimated number of respondents: 

153,083 (total). 

Frequency of response: Varies by 

requirement (i.e., on occasion, monthly, 

quarterly, semi-annually and annually). 

Total estimated burden: 12,930,414 

hours (per year). Burden is defined in 5 

CFR 1320.03(b). 

Total estimated cost: $590,507,000 

(per year), includes $20,386,000 

annualized capital and $115,808,000 

operation and maintenance costs.

Public Water System Supervision 

Program Renewal Information 

Collection Request 

Abstract: The Public Water System 

Supervision (PWSS) Program Renewal 

ICR examines public water system, 

primacy agency and tribal operator 

certification provider burden and costs 

for ‘‘cross-cutting’’ recordkeeping and 

reporting requirements (i.e., the burden 

and costs for complying with drinking 

water information requirements that are 

not associated with contaminantspecific rulemakings). The following 

activities have recordkeeping and 

reporting requirements that are 

mandatory for compliance with 40 CFR 

parts 141 and 142: The Consumer 

Confidence Report Rule (CCR), the 

Variance and Exemption Rule (V/E 

Rule), General State Primacy Activities, 

the Public Notification Rule (PN) and 

Proficiency Testing Studies for Drinking 

Water Laboratories. The information 

collection activities for both the 

Operator Certification Program and the 

Capacity Development Program are 

driven by the grant withholding and 

reporting provisions under sections 

1419 and 1420, respectively, of the Safe 

Drinking Water Act. Although the Tribal 

Operator Certification Program is 

voluntary, the information collection is 

driven by grant eligibility requirements 

outlined in the Drinking Water 

Infrastructure Grant Tribal Set-Aside 

Program Final Guidelines and the Tribal 

Drinking Water Operator Certification 

Program Guidelines. 

Form numbers: None. 

Respondents/affected entities: Entities 

potentially affected by this action are 

new and existing public water systems 

and primacy agencies. 

Respondent’s obligation to respond: 

Mandatory for compliance with 40 CFR 

parts 141 and 142. 

Estimated number of respondents: 

154,938 (total). 

Frequency of response: Varies by 

requirement (i.e., on occasion, monthly, 

quarterly, semi-annually and annually). 

Total estimated burden: 4,113,408 

hours (per year). Burden is defined in 5 

CFR 1320.03(b). 

Total estimated cost: $227,666,000. 

This includes an estimated burden cost

17042 Federal Register / Vol. 80, No. 61 / Tuesday, March 31, 2015 / Notices 

of $40,019,000 for maintenance and 

operational costs. 

Changes in estimates: There is no 

estimated increase or decrease of hours 

in the total estimated respondent 

burden compared with that identified in 

the ICR currently approved by OMB.

Disinfection Byproducts, Chemical and 

Radionuclides Rules ICR examines 

public water system and primacy 

agency burden and costs for 

recordkeeping and reporting 

requirements in support of the chemical 

drinking water regulations. These 

recordkeeping and reporting 

requirements are mandatory for 

compliance with 40 CFR parts 141 and 

142. The following chemical regulations 

are included: The Stage 1 Disinfectants 

and Disinfection Byproducts Rule (Stage 

1 DBPR), the Stage 2 Disinfectants and 

Disinfection Byproducts Rule (Stage 2 

DBPR), the Chemical Phase Rules 

(Phases II/IIB/V), the Radionuclides 

Rule, the Total Trihalomethanes 

(TTHM) Rule, Disinfectant Residual 

Monitoring and Associated Activities 

under the Surface Water Treatment Rule 

(SWTR), the Arsenic Rule, the Lead and 

Copper Rule (LCR) and the Lead and 

Copper Rule Short Term Revisions. 

Future chemical-related rulemakings 

will be added to this consolidated ICR 

after the regulations are promulgated 

and the initial, rule-specific, ICRs are 

due to expire. 

Form numbers: None 

Respondents/affected entities: Entities 

potentially affected by this action are 

new and existing public water systems

program supports Agency decision 

making regarding whether or not to 

regulate particular contaminants in 

drinking water. EPA published the first 

group of contaminants in UCMR 1, in 

the Federal Register on September 17, 

1999 (64 FR 50556), and the second

Note: Sanitary survey burden for surface water systems is included under IESWTR. Sanitary survey burden for ground watincluded under the GWR (see App. G). Number of responses for monitoring for states is based on number of PWS respondents and assumes 1 response per systeState burden for monitoring assumes 15 minutes to review each system's data each month. Burden estimates take into accMay 2015 consultations with water industry representatives.The 3-year period covered by the Microbial Rules ICR includes approximately 3 years of burden for TCR activities (estimatAppendix C1) and 2.5 years of net change burden for RTCR activities (estimated in Appendix C2). Burden and costs assocTCR/RTCR represent the sum of the TCR burden and the net change RTCR burden (i.e., incremental over the 1989 TCR), chapter 6 of the Microbial Rules ICR (see exhibits 6-14). In order to account for the full burden and costs related to RTCR, purposes burden and costs related to TCR are included for the full 3-year evaluation period. RTCR net change burden includes that to conduct routine monitoring, additional routine monitoring, and repeat monitoring; Level 2 assessments; and perform reporting and recordkeeping related to corrective actions.

The 3-year period covered by the Microbial Rules ICR includes approximately 3 years of burden for TCR 

activities (estimated in Appendix C1) and 2.5 years of net change burden for RTCR activities (estimated in this 

appendix, Appendix C2). Burden and costs associated with TCR/RTCR represent the sum of the TCR burden 

and the net change RTCR burden (i.e., incremental over the 1989 TCR), and are shown in chapter 6 of the 

Microbial Rules ICR (see exhibits 6-14). In order to account for the full burden and costs related to RTCR, for 

modeling purposes burden and costs related to TCR are included for the full 3-year evaluation period. 

RTCR net change burden includes that to conduct routine monitoring, additional routine monitoring, and repeat 

monitoring; perform Level 1 and Level 2 assessments; and perform reporting and recordkeeping related to 

corrective actions. Detailed information related to PN activities has been removed from the RTCR standalone 

ICR and is accounted for under the PN Rule in the 2015 PWSS Programmatic ICR.

(B) Under the RTCR, states will not incur additional annual administration burden for ongoing 

implementation of the final RTCR.

(B) Labor hours for start-up activities are based on GWR estimates. Because the final RTCR is a revision 

of the 1989 TCR, one fourth of the State unit start up burden from GWR is used in the final RTCR. 

Implementation is assumed to have been completed in a previous ICR period.

Exhibit C2.34 Costs, Year by Year by Activity (1989 TCR)

Note: TCR costs shown in the exhibit above are used to calculate the RTCR net change in burden and costs (i.e., incremental over the 1989 TCR) for conducting routine monitoring, additional routine monitoring, and repeat 

monitoring; performing Level 1 and Level 2 assessments; and performing reporting and recordkeeping related to corrective actions. Note that detailed information related to PN activities has been removed from the RTCR standal

ICR and is accounted for under the PN Rule in the 2015 PWSS Programmatic ICR.

Notes: 

1) Detail may not add exactly to total due to independent rounding.

2) The first portion of year 1 of the renewal ICR evaluation period is covered under the stand-alone RTCR ICR. Annual average net change burden and costs 

represent burden and costs for years 4, 5, and half of year 6 divided over the 3 year evaluation period. 

3) RTCR net change burden and costs (i.e., incremental burden and costs over the 1989 TCR) includes that incurred to conduct routine monitoring, additional 

routine monitoring, and repeat monitoring; to perform Level 1 and Level 2 assessments; and to perform reporting and recordkeeping related to corrective actions. 

Note that net change burden and costs associated with PN activities are accounted for in the 2015 PWSS Programmatic ICR.

Exhibit F.4 Responses for the ICR Approval Period

Years listed in the following notes are years post-promulgation.(1) Start-up is assumed to have been completed in Years 1-3.(2) This activity was completed in a previous ICR period.(3) Activities associated with uncovered finished water reservoirs are assumed to have been completed in Years 1-3.(4) Systems are assumed to report monthly. This may be an overestimate, since reporting requirements vary with technology used.(5) Disinfection profiling and benchmarking are considered 1 response. Profiling is assumed to be conducted prior to treatment installation.(6) Two responses are associated with the second round of reporting: sampling plan and bin calculation.(7) State start-up activities are assumed to have been completed in Years 1-3.(8) Each State will have 3 responses associated with binning and reviewing monitoring data (see Exhibit F.12). The number of responses froStates and Territories equals three times the number of small systems performing E. coli monitoring in a given year.(9) Activities associated with uncovered finished water reservoirs are assumed to have been completed in Years 1-3.(10) State reviews of disinfection benchmarks will parallel system activities. One response per system conducting benchmarking is assumed

Exhibit F.6b (continued) Labor Rates

E. coli commercial shipping costs were estimated by 

assuming that two 125-mL sample containers would be 

shipped to the laboratory in a 10-quart polyethylene cooler 

packed with approximately 4 lb of UTEK gel packs. 

The approximate weight of the shipment, given these 

assumptions, is 7 lb. Using this weight, we estimated shipping 

costs for standard overnight service for shipments to 12 

locations using the Fed Ex web site.

Total Laboratory 

Average Cost per Plant

[1] Lab costs based on EPA subcontractor (DynCorp) survey of laboratories. 

Cryptosporidium costs assume all plants must send samples to commercial 

laboratories and that 27 percent of samples will require multiple subsamples 

analysis at additional cost (based on Supplemental Survey results). E. coli costs 

are provided for utility analysis (no shipping) and commercial analysis, which 

includes overnight shipping charges. 

[3] Assumes monthly Cryptosporidium monitoring, plus two matrix spike samples 

to be analyzed at the beginning of monitoring and bi-weekly E. coli monitoring. 

These are conservative estimates, therefore laboratory costs could be lower.

[2] Minimum costs are estimated from DynCorp for the minimum analytical cost 

and the mean cost for shipping a 37.6 pound package (average weight of 

sample as observed during the Supplemental Survey, estimated by Kevin 

Connell) overnight (FedEx). Maximum costs are estimated from DynCorp for the 

maximum analytical costs, the mean cost for shipping a 37.6 pound package 

(average weight of sample as observed during the Supplemental Survey, 

estimated by Kevin Connell) overnight (FedEx), and the maximum cost of an 

additional subsample analysis, also estimated by DynCorp.

Thus, the schedule reflects treatment installation. [6] Assessments for re-binning: A second round of E. coli and Cryptosporidium monitoring for re-binning for a given system began 6.5 years after that system's completion of initial monitoring.[7] In the first round of monitoring, States will perform these activities for small systems only; States will perform these activities for all systems during the second round of monitoring.[8] State activities associated with uncovered finished water reservoirs are assumed to have been completed during Years 2-3.[9] State activities will parallel system activities. [10] State activities will parallel system activities. This ICR only characterizes burden and costs associated with systems complying with LT2ESWTR. Estimates of disinfection and profiling burden and costs associated with systems changing treatment to compStage 2 DBPR are not yet available; they will be added in future ICRs.[1] Start-up burden is assumed to have been completed in Years 1-3.[2] The first round of E. coli and Cryptosporidium monitoring was completed during a previous ICR clearance period.

[3] Activities associated with uncovered finished water reservoirs are assumed to have been completed in Years 1-3. [4] Systems must begin to demonstrate compliance with technologies 42 months following the completion of Cryptosporidium monitoring.

Notes:[10] State activities will parallel system activities. [4] Systems must begin to demonstrate compliance with technologies 42 months following the completion of Cryptosporidium monitoring. [5] Disinfection profiling must be completed prior to changing the disinfection process. Thus, the schedule reflects treatment installation. [6] Assessments for re-binning: A second round of E. coli and Cryptosporidium monitoring for re-binning for a given system began 6.5 years after that system's completion of initial monitoring.[7] In the first round of monitoring, States will perform these activities for small systems only; States will perform these activities for all systems during the second round of monitoring.[8] States are assumed to have completed review of uncovered finished water reservoir reports during Years 2-3.[9] State activities will parallel system activities. This ICR only characterizes burden and costs associated with systems complying with LT2ESWTR. Estimates of disinfection and profiling burden and costs associated with systems changing treatment to comply with Stage 2 DBPR are not yet a

1) Burden estimates take into account the results of May 2015 consultations with water industry representatives.2) Weighted unit costs equal 5% of the unit costs. This factor accounts for 50% effort for an incremental survey and 10% of systems that do not already comply with rule requirements (see Chapter 6, Sec. 6.4.2 of the GWR EA for discussion).(D) Unit costs for NTNCWSs may be over-estimated because some of these systems may not have a distribution system.

Total labor burden for reviewing invenlabor burden * # of air carriers.(E) Total cost for reviewing monitoring results = unit cost * total number of TC+ samples (Exhibit H.10a). Total cost for reviewing inventory = unit cost * total burreviewing inventory.(F) Air carriers were required to report their water system inventory within 18 months of promulgation and are required to update that inventory annually. The insubmission of inventory information was assumed to be submitted as part of the sampling plan. This burden reflects only the annual inventory updates.Note:(1) Total Agency burden and labor costs for ADWR are accounted for in the PWSS Program ICR since this rule is directly implemented through the EPA Regioburden and cost calculations shown here are for informational purposes only.
