EPA ICR No. 1895.08, OW–2011–0442

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 regulationsare 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.

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.

EPA ICR No. 0270.46, OW–2011–0443 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.

EPA ICR No. 1896.10, OW–2011–0439 Disinfectants/Disinfection Byproducts,

Chemical and Radionuclides Rules Information Collection Request

Abstract: The Disinfectants/ 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 and primacy agencies.

Respondent’s obligation to respond: Mandatory for compliance with 40 CFR parts 141 and 142.

Estimated number of respondents:

153,036.

Frequency of response: Varies by requirement ( i.e., on occasion, monthly, quarterly, semi-annually, annually, biennially and every 3, 6 and 9 years).

Total estimated burden: 5,734,335 hours (per year). Burden is defined in 5 CFR 1320.03(b).

Sanitary survey burden for ground water systems isincluded 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 system per month.State burden for monitoring assumes 15 minutes to review each system's data each month. Burden estimates take into account the results ofMay 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 (estimated in this appendix,Appendix C1) and 2.5 years of net change burden for RTCR activities (estimated in Appendix C2). Burden and costs associated withTCR/RTCR represent the sum of the TCR burden and the net change RTCR burden (i.e., incremental over the 1989 TCR), and are shown inchapter 6 of the Microbial Rules ICR (see exhibits 6-14). In order to account for the full burden and costs related to RTCR, for modelingpurposes 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 andLevel 2 assessments; and perform reporting and recordkeeping related to corrective actions. Detailed information related to PN activities hasbeen removed from the RTCR standalone ICR and is accounted for under the PN Rule in the 2015 PWSS Programmatic ICR.Microbial Rules ICR - Total Coliform RuleC1 -

C2.37 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.

Note:
[1] IESWTR individual filter turbidity monitoring requirements apply only to systems serving more than 10,000 people. The turbi dity monitoring requirements do not apply to systems using slow
sand or diatomaceous earth filtration; however, they do apply to systems using other alternative technologies, but the number o f such systems is assumed to be negligible and is not included
here. The percentage of plants using conventional or direct filtration (from the CWSS) was assumed to apply to NTNCWSs and TNCW Ss. Percentage of systems using conventional or direct
filtration was not available. Percentage of plants was used as a proxy.

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
Cost per Plant Average

[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. Analyte

# Exhibit F.18 State Burden and Cost for Disinfection Benchmarking Reports

(D) All systems changing disinfection (regardless of the reason) must be included in the LT2 benchmarking report to show that t hey are
providing the required level of disinfection. Note that column D only includes the number of systems changing disinfection to c omply with
LT2ESWTR. Systems are also expected to change treatment under Stage 2 DBPR; however, the number of systems changing treatment t o comply with Stage 2 DBPR is not yet available; it will be added in future ICRs.

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). 

# Exhibit G.7a PWS Unit Burden and Cost Estimates for Performing Full and
Incremental Sanitary Surveys (Treatment)

(D) Unit costs for NTNCWSs may be over-estimated because some of these systems may not have a distribution system. 1) Burden estimates take into account the results of May 2015 consultations with water industry representatives.

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).

Each aircraft with a total coliform-positive sample takes two follow-up samples after completingcorrective action.(E) From column D, Exhibit H.12b. Includes only those corrective actions that do not overlap with routine disinfection and flushing. Assumes a one-to-one correspondence between corrective action and aircraft.(F) Percentage of aircraft restricting public access from 2013 ARCS data. Air carriers that choose to take longer than 72 hours to conduct corrective action must restrict public access and provide public notification.(K) EPA estimate, based on burden for preparing a Tier 2 public notice in the Public Water System Supervision ICR. Includes time needed to prepare notice for crew, post placard for passengers (where required), and report toEPA.Total Coliform-Positive SamplesE. coli-Positive SamplesTotal PN BurdenTotal PN Costs(I) Percentage of routine samples positive forE. colifrom 2013 ARCS data. All air carriers with positiveE. colisamples must restrict public access and provide public notification on the affected aircraft. Note thatE. colipositive repeat samples also trigger the same requirements; however they occur so rarely that they do not significantly affect the number of PN events, so they were not included.Microbial Rules ICR - ADWRH-22August 2015
