Records Governing Off-the-Record 

Communications; Public Notice 

April 18, 2008. 

This constitutes notice, in accordance 

with 18 CFR 385.2201(b), of the receipt 

of prohibited and exempt off-the-record 

communications. 

Order No. 607 (64 FR 51222, 

September 22, 1999) requires 

Commission decisional employees, who 

make or receive a prohibited or exempt 

off-the-record communication relevant 

to the merits of a contested proceeding, 

to deliver to the Secretary of the 

Commission, a copy of the 

communication, if written, or a 

summary of the substance of any oral 

communication. 

Prohibited communications are 

included in a public, non-decisional file 

associated with, but not a part of, the 

decisional record of the proceeding. 

Unless the Commission determines that 

the prohibited communication and any 

responses thereto should become a part 

of the decisional record, the prohibited 

off-the-record communication will not 

be considered by the Commission in 

reaching its decision. Parties to a 

proceeding may seek the opportunity to 

respond to any facts or contentions 

made in a prohibited off-the-record 

communication, and may request that 

the Commission place the prohibited 

communication and responses thereto 

in the decisional record. The 

Commission will grant such a request 

only when it determines that fairness so 

requires. Any person identified below as 

having made a prohibited off-the-record 

communication shall serve the 

document on all parties listed on the 

official service list for the applicable 

proceeding in accordance with Rule 

2010, 18 CFR 385.2010. 

Exempt off-the-record 

communications are included in the 

decisional record of the proceeding, 

unless the communication was with a 

cooperating agency as described by 40 

CFR 1501.6, made under 18 CFR 

385.2201(e) (1) (v). 

The following is a list of off-therecord communications recently 

received by the Secretary of the 

Commission. The communications 

listed are grouped by docket numbers in

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 very small businesses (those that 

employ less than 25) on examples of 

specific additional efforts that EPA 

could make to reduce the paperwork 

burden for very small businesses 

affected by this collection. 

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. 

You may also provide the name, date, 

and Federal Register citation. 

What Information Collection Activity or 

ICR Does This Apply to? 

Affected entities: New and existing 

public water systems (PWS), primacy 

agencies, and EPA. 

Title: Microbial Rules (Renewal). 

ICR numbers: EPA ICR No. 1895.04, 

OMB Control No. 2040–0205. 

ICR status: This ICR is currently 

scheduled to expire on September 30, 

2008. 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 public water 

system, 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), and 

Ground Water Rule. Future microbialrelated rulemakings will be added to 

this consolidated ICR after the 

regulations are finalized and the initial, 

rule-specific, 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 


PWALKER on PROD1PC71 with NOTICES
Federal Register / Vol. 73, No. 110 / Friday, June 6, 2008 / Notices 32325 

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: 161,274. 

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: 

9,151,424 hours. 

Estimated total annual costs: 

$118,653,327. This includes an 

estimated burden cost of $14,698,327 

and an estimated cost of $22,793,000 for 

capital investment and $81,162,000 for 

maintenance and operational costs. 

Are There Changes in the Estimates 

From the Last Approval? 

There is an increase of 526,559 hours 

in the total estimated respondent 

burden compared with that identified in 

the ICR currently approved by OMB. 

This increase is primarily due to 

restructuring adjustments (i.e., 

incorporation of the approved burden 

hours from the previously stand-alone 

ICRs for the Long Term 2 Enhanced 

Surface Water Treatment Rule, and 

Ground Water Rule 

What Is the Next Step in the Process for 

This ICR? 

EPA will consider the comments 

received and amend the ICR as 

appropriate. The final ICR package 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 ICR to 

OMB and the opportunity to submit 

additional comments to OMB. If you 

have any questions about this ICR or the 

approval process, please contact the 

technical person listed under FOR

Notes: Labor estimates take into account the results of February 2008 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.

Exhibit F-B.1b (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.

(A & B) Burden estimates take into account the results of the February 2008 consultation with water industry representatives.(D) For systems serving up to 3,300 people, the full technical rate was applied. For systems serving more than 3,300 people, costs are based on an 80%/20% split between technical and managerial rates. Technical rates are from BLS (2006), adjusted to $2007. Managerial rates are based on 

Labor Costs for National Drinking Water Rules (USEPA, 2003), inflated to $2007.(E) Taken from Exhibit F-B.1, column A.

The decrease in burden for small plants that report E. coli but are exempt from Cryptosporidium monitoring is also assumed to be negligible.(D) For systems serving up to 3,300 people, the full technical rate was applied. For systems serving more than 3,300 people, costs are based on an 80%/20% split between technical and managerial rates. Technical rates are from BLS (2006), adjusted to $2007. Managerial rates are based on Labor Costs for National Drinking Water Rules (USEPA, 2003), inflated to $2007.

are based on an 80%/20% split between technical and managerial rates. Technical rates are from BLS (2006), adjusted to $2007. Managerial rates are based on Labor Costs for National Drinking Water Rules (USEPA, 2003), inflated to $2007.

Exhibit F-B.12 Plant Burden and Cost for Disinfection Benchmarking Reports

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 fall outside of the clearance period and will be added in future ICRs.

Exhibit F-B.16 Burden and Cost to Plants Associated with Reporting for Source Water Sampling Schedule and Bin Re-Classific

Monitoring 

(A), (B) Based on the results of February 2008 consultation with water system industry representatives. (E) Taken from Exhibit F-B.1, column I.(D) For systems serving up to 3,300 people, the full technical rate was applied. For systems serving more than 3,300 people, costs are based on an 80%split between technical and managerial rates. Technical rates are from BLS (2006), adjusted to $2007. Managerial rates are based on Labor Costs for NaDrinking Water Rules (USEPA, 2003), inflated to $2007.
