Federal Register Notice Soliciting 

Comments on Information Collection 

Requests 
39092 Federal Register / Vol. 76, No. 128 / Tuesday, July 5, 2011 / Notices 

Abstract: Source Compliance and 

State Action Reporting is an activity 

whereby State, District, Local, and 

Commonwealth governments (hereafter 

referred to as either ‘‘states/locals’’ or 

‘‘state and local agencies’’) make air 

compliance and enforcement 

information available to the U.S. 

Environmental Protection Agency (EPA 

or the Agency) on a cyclic basis via 

input to the Air Facility System (AFS). 

The information provided to EPA 

includes compliance activities and 

determinations, and enforcement 

activities. EPA uses this information to 

assess progress toward meeting 

emission requirements developed under 

the authority of the Clean Air Act (CAA 

or the Act) to protect and maintain the 

atmospheric environment and the 

public health. The EPA and many of the 

state and local agencies access the data 

in AFS to assist them in the 

management of their air pollution 

control programs. This renewal 

information collection request (ICR) 

affects oversight of approximately 

39,005 stationary sources by 99 state 

and local agencies and the Federal EPA. 

On average, the burden imposed by this 

collection amounts to approximately 

one-tenth of a full-time equivalent 

employee for each small state and local 

agency, one-fourth of a full-time 

equivalent employee for each medium 

sized state and local agency and one and 

one-tenth of a full-time equivalent 

employee for each large sized state and 

local agency for national reporting of 

compliance and enforcement related 

data under all of the applicable Clean 

Air Act programs. 

Burden Statement: The annual public 

reporting and recordkeeping burden for 

this collection of information is 

estimated to average 92 hours per 

response. Burden means the total time, 

effort, or financial resources expended 

by persons to generate, maintain, retain, 

or 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 systems 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 which have subsequently 

changed; 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. 

Respondents/Affected Entities: State 

and Local Agencies. 

Estimated Number of Respondents: 

99. 

Frequency of Response: Every 60 

days. 

Estimated Total Annual Hour Burden: 

54,384. 

Estimated Total Annual Cost: 

$2,843,187 in labor costs. There are no 

capital or O&M costs. 

Changes in the Estimates: There is a 

decrease of 18,689 hours in the total 

estimated burden currently identified in 

the OMB Inventory of Approved ICR 

Burdens. This decrease is due to a 

continuing decrease in the number of 

major sources in the reportable universe 

and a reported decrease of time and 

resources available for use in data 

management by small and medium 

sized agencies.

SUPPLEMENTARY INFORMATION: 

How can I access the docket and/or 

submit comments? 

EPA has established a public docket 

for each of the ICRs identified in the 

ADDRESSES section, which are available 

for online viewing at http:// 

www.regulations.gov, or in person 

viewing at the Water Docket in the EPA 

Docket Center (EPA/DC), EPA West, 

Room 3334, 1301 Constitution Ave., 

NW., Washington, DC. The EPA/DC 

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 Reading Room 

is 202–566–1744, and the telephone 

number for the Water Docket is 202– 

566–2426. 

Use http://www.regulations.gov to 

obtain a copy of the draft collection of 

information, submit or view public 

comments, access the index listing of 

the contents of the docket, and to access 

those documents in the public docket 

that are available electronically. Once in 

the system, select ‘‘search,’’ then key in 

the docket ID number identified in this 

document. 

What information is EPA particularly 

interested in? 

Pursuant to section 3506(c)(2)(A) of 

the PRA, EPA specifically solicits 

comments and information to enable it 

to: 

(i) Evaluate whether the proposed 

collection of information is necessary 

for the proper performance of the 

functions of the Agency, including 

whether the information will have 

practical utility; 

(ii) evaluate the accuracy of the 

Agency’s estimate of the burden of the 

proposed collection of information, 

including the validity of the 

methodology and assumptions used; 

(iii) enhance the quality, utility, and 

clarity of the information to be 

collected; and 

(iv) minimize the burden of the 

collection of information on those who 

are to respond, including through the 

use of appropriate automated electronic, 

mechanical, or other technological 

collection techniques or other forms of 

information technology, e.g., permitting 

electronic submission of responses. In 

particular, EPA is requesting comments 

from small public water systems (those 

that serve less than 10,000 customers) 

on examples of specific additional 

efforts that EPA could make to reduce 

the paperwork burden for small public 

water systems affected by this 

collection. The small public water 

systems include community water 

systems, and non-transient noncommunity water systems such as 

schools and hospitals, in addition to 

transient non-community water systems 

such as restaurants and campgrounds. 

What should I consider when I prepare 

my comments for EPA? 

You may find the following 

suggestions helpful for preparing your 

comments: 

1. Explain your views as clearly as 

possible and provide specific examples. 

2. Describe any assumptions that you 

used. 

3. Provide copies of any technical 

information and/or data you used that 

support your views. 

4. If you estimate potential burden or 

costs, explain how you arrived at the 

estimate that you provide. 

5. Offer alternative ways to improve 

the collection activity. 

6. Make sure to submit your 

comments by the deadline identified 

under DATES. 

7. To ensure proper receipt by EPA, 

be sure to identify the docket ID number 

assigned to this action in the subject 

line on the first page of your response.

What information collection activity or 

ICR does this apply to? 

Docket ID No. EPA–HQ–OW–2011– 

0439. 

Affected entities: Entities potentially 

affected by this action are new and 

existing public water systems (PWS), 

primacy agencies, and EPA. 

Title: Disinfectants/Disinfection 

Byproducts, Chemical, and 

Radionuclides Rules (Renewal). 

ICR numbers: EPA ICR No. 1896.09, 

OMB Control No. 2040–0204. 

ICR status: This ICR is currently 

scheduled to expire on December 31, 

2011. An Agency may not conduct or 

sponsor, and a person is not required to 

respond to, a collection of information, 

unless it displays a currently valid OMB 

control number. The OMB control 

numbers for EPA’s regulations in title 40 

of the CFR, after appearing in the 

Federal Register when approved, are 

listed in 40 CFR part 9, are displayed 

either by publication in the Federal 

Register or by other appropriate means, 

such as on the related collection 

instrument or form, if applicable. The 

display of OMB control numbers in 

certain EPA regulations is consolidated 

in 40 CFR part 9. 

Abstract: The Disinfectants/ 

Disinfection Byproducts, Chemical and 

Radionuclides Rules ICR examines 

PWS, primacy agency and EPA 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: Stage 1 Disinfectants and 

Disinfection Byproducts Rule (Stage 1 

DBPR), Stage 2 Disinfectants and 

Disinfection Byproducts Rule (Stage 2 

DBPR), Chemical Phase Rules (Phases 

II/IIB/V), 1976 Radionuclides Rule and 

2000 Radionuclides Rule, Total 

Trihalomethanes (TTHM) Rule, 

Disinfectant Residual Monitoring and 

Associated Activities under the Surface 

Water Treatment Rule, Arsenic Rule, 

Lead and Copper Rule (LCR) and 

revisions. Future chemical-related 

rulemakings will be added to this 

consolidated ICR after the regulations 

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

Burden Statement: The annual public 

reporting and recordkeeping burden for 

this collection of information is 

estimated to average 0.40 hours per 

response. Burden means the total time, 

effort, or financial resources expended 

by persons to generate, maintain, retain, 

or 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 systems 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 which have subsequently 

changed; 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. 

The ICR provides a detailed 

explanation of the Agency’s estimate, 

which is only briefly summarized here: 

Estimated total number of potential 

respondents: 246,048. 

Frequency of response: varies by 

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

quarterly, semi-annually, annually, 

biennially, and every 3, 6, and 9 years). 


srobinson on DSK4SPTVN1PROD with NOTICES
39094 Federal Register / Vol. 76, No. 128 / Tuesday, July 5, 2011 / Notices 

Estimated total average number of 

responses for each respondent: varies by 

requirement. 

Estimated total annual burden hours: 

6,987,131 hours. 

Estimated total annualized capital/ 

startup costs: $6,918,000. 

Estimated total annual maintenance 

and operational costs: $203,672,204. 

Are there changes in the estimates from 

the last approval? 

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. 

What information collection activity or 

ICR does this apply to? 

Docket ID No. EPA–HQ–OW–2011– 

0442. 

Affected entities: Entities potentially 

affected by this action are new and 

existing public water systems (PWS), 

primacy agencies, and EPA. 

Title: Microbial Rules (Renewal). 

ICR numbers: EPA ICR No. 1895.07, 

OMB Control No. 2040–0205 

ICR status: This ICR is currently 

scheduled to expire on April 30, 2012. 

An Agency may not conduct or sponsor, 

and a person is not required to respond 

to, a collection of information, unless it 

displays a currently valid OMB control 

number. The OMB control numbers for 

EPA’s regulations in title 40 of the CFR, 

after appearing in the Federal Register 

when approved, are listed in 40 CFR 

part 9, are displayed either by 

publication in the Federal Register or 

by other appropriate means, such as on 

the related collection instrument or 

form, if applicable. The display of OMB 

control numbers in certain EPA 

regulations is consolidated in 40 CFR 

part 9. 

Abstract: The Microbial Rules 

Renewal ICR examines PWS, primacy 

agency and EPA 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 with 40 CFR parts 141 and 

142. The following microbial 

regulations are included: Surface Water 

Treatment Rule (SWTR), Total Coliform 

Rule (TCR), Interim Enhanced Surface 

Water Treatment Rule (IESWTR), Filter 

Backwash Recycling Rule (FBRR), Long 

Term 1 Enhanced Surface Water 

Treatment Rule (LT1ESWTR), Long 

Term 2 Enhanced Surface Water 

Treatment Rule (LT2ESWTR), Ground 

Water Rule, and the Aircraft Drinking 

Water Rule. Although the Aircraft 

Drinking Water Rule has a stand-alone 

ICR at this time, it is being included into 

the Microbial ICR due to the nature of 

information collected. The information 

collected for the Aircraft Drinking Water 

Rule is directly correlated to 

information collected under the Total 

Coliform Rule, and therefore is 

appropriate to be included in the 

Microbial ICR. Future microbial-related 

rulemakings will be added to this 

consolidated ICR after the regulations 

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

Burden Statement: The annual public 

reporting and recordkeeping burden for 

this collection of information is 

estimated to average 0.79 hours per 

response. Burden means the total time, 

effort, or financial resources expended 

by persons to generate, maintain, retain, 

or 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 systems 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 which have subsequently 

changed; 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. 

The ICR provides a detailed 

explanation of the Agency’s estimate, 

which is only briefly summarized here: 

Estimated total number of potential 

respondents: 161,337. 

Frequency of response: Varies by 

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

quarterly, semi-annually, and annually. 

Estimated total average number of 

responses for each respondent: 72. 

Estimated total annual burden hours: 

9,172,188 hours. 

Estimated total annualized capital/ 

startup costs: $32,888,601. 

Estimated total annual maintenance 

and operational costs: $88,222,000. 

Are there changes in the estimates from 

the last approval? 

There is an increase of 17,583 hours 

in the total estimated respondent 

burden compared with that identified in 

the ICR currently approved by OMB. 

This increase reflects EPA’s inclusion of 

the information collection requirements 

of the Aircraft Drinking Water Rule, 

which was previously a stand-alone 

ICR. 

What information collection activity or 

ICR does this apply to? 

Docket ID No. EPA–HQ–OW–2011– 

0443. 

Affected entities: Entities potentially 

affected by this action are new and 

existing public water systems (PWS), 

primacy agencies, and EPA. 

Title: Public Water System 

Supervision Program (Renewal). 

ICR numbers: EPA ICR No. 0270.45, 

OMB Control No. 2040–0090. 

ICR status: This ICR is currently 

scheduled to expire on March 31, 2012. 

An Agency may not conduct or sponsor, 

and a person is not required to respond 

to, a collection of information, unless it 

displays a currently valid OMB control 

number. The OMB control numbers for 

EPA’s regulations in title 40 of the CFR, 

after appearing in the Federal Register 

when approved, are listed in 40 CFR 

part 9, are displayed either by 

publication in the Federal Register or 

by other appropriate means, such as on 

the related collection instrument or 

form, if applicable. The display of OMB 

control numbers in certain EPA 

regulations is consolidated in 40 CFR 

part 9. 

Abstract: The Public Water System 

Supervision (PWSS) Program Renewal 

ICR examines PWS, primacy agency, 

EPA, and tribal operator certification 

provider burden and costs for ‘‘crosscutting’’ recordkeeping and reporting 

requirements (i.e., the burden and costs 

for complying with drinking water 

information requirements that are not 

associated with contaminant-specific 

rulemakings). These activities which 

have record keeping and reporting 

requirements that are mandatory for 

compliance with 40 CFR parts 141 and 

142 include the following: Consumer 

Confidence Reports (CCRs), Primacy 

Regulation Activities, Variance and 

Exemption Rule (V/E Rule), General 

State Primacy Activities, Public 

Notification (PN) and Proficiency 

Testing Studies for Drinking Water 

Laboratories. The information collection 

activities for both the Operator 

Certification/Expense Reimbursement 

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.

received and amend the ICRs as 

appropriate. The final ICR packages will 

then be submitted to OMB for review 

and approval pursuant to 5 CFR 

1320.12. At that time, EPA will issue 

another Federal Register notice pursuant 

to 5 CFR 1320.5(a)(1)(iv) to announce 

the submission of the ICRs to OMB and 

the opportunity to submit additional 

comments to OMB. If you have any

Compatibility of Underground Storage 

Tank Systems With Biofuel Blends 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of final guidance. 

SUMMARY: EPA is issuing final guidance 

on how owners and operators of 

underground storage tanks (USTs) can 

demonstrate compliance with the 

Federal compatibility requirement for 

UST systems storing gasoline containing 

greater than 10 percent ethanol or diesel 

containing greater than 20 percent 

biodiesel. 

ADDRESSES: EPA established a docket 

for this action under Docket ID No. 

EPA–HQ–UST–2010–0651. All 

documents and public comments in the 

document are available at http:// 

www.regulations.gov or in hard copy at 

the UST Docket in the EPA 

Headquarters Library, located at EPA 

West Building, Room 3334, 1301 

Constitution Ave., NW., Washington, 

DC 20460. The Public Reading Room is 

open from 8:30 a.m. to 4:30 p.m., 

Monday through Friday, excluding 

Federal holidays. The telephone number

603–7137; e-mail address: 

barbery.andrea@epa.gov. 

SUPPLEMENTARY INFORMATION: 

I. General Information 

A. Does this action apply to me? 

This guidance is for owners and 

operators of underground storage tank 

(UST) systems (hereafter referred to as 

tank owners) regulated by 40 CFR Part 

280, who intend to store gasoline 

blended with greater than 10 percent 

ethanol or diesel blended with greater 

than 20 percent biodiesel. 

40 CFR Part 280, and therefore this 

guidance, applies in Indian country and 

in states and territories (hereafter 

referred to as states) that do not have 

state program approval (SPA). You can 

view a map of SPA states with approved 

UST programs at: http://www.epa.gov/ 

oust/states/spamap.htm. SPA states 

may find this guidance relevant and 

useful because they also have a 

compatibility requirement that is similar 

to the Federal compatibility 

requirement. You can view statespecific requirements for SPA states at: 

http://www.epa.gov/oust/fedlaws/ 

spa_frs.htm. 

B. How can I get copies of this document

A. Statutory Authority 

This guidance discusses the Federal 

UST compatibility requirement 

promulgated under the authority of 

Subtitle I of the Solid Waste Disposal 

Act (SWDA), as amended. 42 U.S.C. 

6991b et seq. You can find this 

requirement, which is referenced and 

discussed in the guidance, in 40 CFR 

280.32. 

B. Underground Storage Tank 

Compatibility Requirement 

To protect groundwater, a source of 

drinking water for nearly half of all 

Americans, the U.S. Environmental 

Protection Agency (EPA) regulates UST 

systems storing petroleum or hazardous 

substances under authority of Subtitle I 

of the Solid Waste Disposal Act 

(SWDA), as amended. Tanks storing

Notes:Burden estimates take into account the results of December 2011 consultations with water industry representatives. Overall sample costs are conservative estimates. Many systems now use a method allowing for both total coliforms and fecal/E.coli to be tested at one time. Average sample cost based on research conducted for the Aircraft Drinking Water Rule in Nov. 2006.

(E) Exception reports are required when systems exceed turbidity levels of 0.5 or 1 NTU in consecutive measurements in individual filters (absent such exceedances, systems 

need only report that they have completed monitoring). 

(F) Comprehensive performance evaluations are performed by states when a system exceeds 2 NTU in two consecutive measurements in an individual filter in each of two 

consecutive months.

(I, J) Burden estimates take into account the results of December 2011 consultations with water industry representatives (including states).

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 the 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 from States 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 paks. 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.

Exhibit F.22 12-Year Summary of Burden Associated with Implementing the LT2ESWTR (Hours)

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 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 the previous ICR clearance period.

[6] Assessments for re-binning: A second round of E. coli and Cryptosporidium monitoring for re-binning for a given system will begin 6.5 years after that system's completion of initial 

monitoring.

Exhibit G.7d State Unit Burden and Cost Estimates for Performing Full and Incremental Sanitary Surveys (No Treatment)

1) Burden estimates take into account the results of December 2011 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 alreacomply 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.

(D) Air carrier labor costs from Exhibit H.2. EPA used the transportation inspector category because it was the highest-paid technical labor category. Transportation inspectors are ashave a technical background, as well as some management or oversight responsibility.(E) EPA assumes that air carriers already conduct major maintenance checks, which include sanitary survey components, every 5 years for each aircraft. Therefore, with the exceptiand recordkeeping burden, no additional costs for sanitary surveys are incurred by air carriers under the ADWR.(F), (G) All aircraft undergo compliance audits once in 5 years. The Agency will review electronic data for all aircraft at the air carrier office site. Fractional costs incurred by aircraft (adistribution across aircraft of all sizes) are represented in the exhibit for presentation and calculation purposes only.
