1. Identification of the Information Collection 1(a) Title of the Information Collection NSPS for Sewage Sludge Treatment Plants (40 CFR part 60, subpart O) (Renewal) , EPA I CR Number 1063.11, OM B Control Number 2060

- 0035 1(b) Short Characterization/Abstract The New Source Performance Standards (NSPS) for Sewage Sludge Treatment Plant Incinerators (40 CFR part 60, subpart O) were promulgated on February 28, 1974 (39 FR 9312) and amended on Octo ber 6, 1975, November 10, 1977, October 6, 1988, and October 17, 2000. These standards apply to each incinerator which combusts wastes containing more than 10 percent sewage sludge (dry basis) produced by

municipal sewage treatment plants or each incinerator which charges more than 1000 kg (2205 lb.) per day

municipal sewage sludge (dry basis), and any

facility that commenced construction or modification after June 11, 1973. Particulate matter (PM) is the pollutant regulated under this subpart. The standard sets an emission limitation for PM. This information is being collected to assure compliance with this regulation

. Approximately 112 facilities with 218 units are currently subject to the standard. Itis estimated that two new units will be built o ver the next five years or 1.2 additional source s will become subject to the regulation over the next three years. The average annual cost to industry over the next three years of this In formation Collection Request (I CR) is estimated to be $ 1,178,948 in labor, and $ 3,96 0,000 in annualized capital/startup costs and operating & maintenance (O&M)

. OMB approved the current I CR without any “ Terms of Clearance. ” 2. Need for and Use of the Collection 2(a) Need/Authority for the Collection The EPA is charge d under Section 111 of the Clean Air Act (CAA), as amended, to establish standards of performance for new stationary sources that reflect: . . . application of the best technological sy stem of continuous emissions reduction which (taking into consideratio n the cost of achieving such emissions reduction, or any non - air quality

health and environmental impact and energy

requirements) the Administrator determines has been adequately demonstrated. Section 111(a)(l). The Agency

refers to this charge as selecti ng the best demonstrated technology (BDT). Section 111 also requires that the Administrator review and, if appropriate, revise such standards every eight ye ars.2

Inthe Administrator’ s judgment, particulate matter emissions from sewage sludge treatment pl ant incinerators either cause or contribute to air pollution that may reasonably

be anticipated to endanger public health or welfare. Therefore, the NSPS were promulgated for this source category at 40 CFR part 60, subpart O. 2(b) Practical Utility/User s of the Data The control of emissions of particulate matter from sewage sludge treatment plant incinerators requires not only

the installation of properly designed equipment, but also the operation and maintenance of that equipment. Emissions of particu late matter from sewage sludge treatment plant incinerators are the result of operation of the affected facilities. The subject standards are achieved by the reduction of particulate matter emissions using control technology and leak detection and repair procedures. The recordkeeping and reporting requirements in the standard ensures compliance with the applicable regulations which where promulgated in accordance with the Clean Air Act. The collected information is also used for targeting inspections a nd as evidence in legal proceedings. Performance tests are required in order to determine an affected facility ’s initial capability to comply with the emission standard(s). Continuous emission monitors are used to ensure compliance with the standard(s) at all times. The notifications required in the standard(s) are used to inform the Agency or delegated authority

when a source becomes subject to the requirements of the regulations. The reviewing authority may then inspect the source to check if the pollut ion control devices are properly installed and operated and the standard(s) are being met. The performance test may also be observed. The required semiannual reports are used to determine periods of excess emissions, identify problems at the facility , ve rify operation/maintenance procedures and for compliance determinations. 3. Non
- duplication, Consultations, and Other Collection Criteria The requested recordkeeping and reporting are required under 40 CFR part 60, subpart O

. 3(a) Non
- duplication If the subject standards have not been delegated, the information is sent directly to the appropriate EPA regional office. Otherwise, the information is sent directly to the delegated state or local agency . I f a state or local agency

has adopted its own sim ilar standards to implement the Federal standards, a copy of the report submitted to the state or a local agency can be sent to the Administrator in lieu of the report required by

the Federal standards. Therefore, no duplication exists. 3(b) Public Noti ce Required Prior to ICR Submission to OMB An announcement of a public comment period for the renewal of this I CR was published in the Federal Register on July

8, 2009 ( 74 FR 32580 ). No comments were received on the burden published in the Federal Regist er .3

3(c) Consultations The Agency

based the number of sources for this I CR on estimates in the upcoming NSPS/Emission Guidelines (EG) for Sewage Sludge In cinerators . T he Agency has consulted with the National Association of Clean Water Agencies to upd ate the inventory of facilities and sources and refine the inventory further based on new information collected from the I CR, permits, states, and state public databases

. Itis our policy

to respond after a thorough review of comments received since the l ast I CR renewal as well as thos e submitted in response to the first Federal Register n otice. Inthis case, no comments were received. 3(d) Effects of Less Frequent Collection Less frequent information collection would decrease the margin of assurance that facilities are continuing to meet the standards. Requirements for information gathering and recordkeeping are useful techniques to ensure that good operation and maintenance practices are applied and emission limitations are met. I f the information required by these standards was collected less frequently , the proper operation and maintenance of control equipment and the possibility of detecting violations would be less likely

. 3(e) General Guidelines These reporting or recordkeeping requirements do not violate any of the regulations promulgated by OMB under 5 CFR part 1320, section 1320.5. 3(f) Confidentiality Any information submitted to the Agency for which a claim of confidentiality is made will be safeguarded according to the Agency polici es set forth in Title 40, Chapter 1, part 2, subpart B

- Confidentiality

of Business Information (CBI ) (see 40 CFR 2; 41 FR 36902, September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979). 3(g) Sensitive Questions The reporting or recordkeeping requirements in the standard do not include sensitive questions. 4. The Respondents and the Information Requested 4(a) Respondents/NAIC Codes The respondents to the recordkeeping and reporting requirements are sewage sludge treatment plants The United States Standard Industrial Classification (SI C) code for the respondents affected by the standards is 4952, which corresponds to the NAI CS (The North American Industry Classification Sy stem) 22132 0 for Sewage Sludge Treatment Plants.4

Maintain records for two years. 60.7(f)6

Electronic Reporting Some of the respondents are using monitoring equipment that automatically records parameter data. Although personnel at the affected facility must still evaluate the data, internal automation has significantly reduced the burden associated with monitoring and recordkeeping at a plant site. Also, regulatory

agencies in cooperation with the respondents, c ontinue to create reporting sy stems to transmit data electronically . However, electronic reporting sy stems are still not widely used. At this time, it is estimated that approximately 10 percent of the respondents use electronic reporting. (ii) Responde nt Activities Respondent Activities Read instructions. In stall, calibrate, maintain, and operate a Continuous Monitoring Sy stem (CMS) for opacity , or for pressure drop and liquid supply pressure for wet scrubber. Perform initial performance test, Reference Method 5 and 9 test, and repeat performance tests if necessary

. Write the notifications and reports listed above. Enter information required to be recorded above. Submit the required reports developing, acquiring, installing, and utilizing technology and sy stems for the purpose of collecting, validating, and verifying information. Develop, acquire, install, and utilize technology and sy stems for the purpose of processing and maintaining information. Develop, acquire, install, and utilize technology and sy stems for the purpose of disclosing and providing information. Adjust existing way s to comply with any previously

applicable instructions and requirements. Train personnel to be able to respond to a collection of information. Transm it, or otherwise disclose the information. Currently , sources are using automated monitoring equipment that provides parameter data. Although personnel at the source still need to evaluate the data, this ty pe of monitoring equipment has significantly

re duced the burden associated with monitoring and recordkeeping.7

5. The Information Collected: Agency Activities, Collection Methodology, and Information Management 5(a) Agency Activities EPA conducts the following activities in connection with the acq uisition, analy sis, storage, and distribution of the required information. Agency Activities Observe initial performance tests and repeat performance tests if necessary

. Review notifications and reports, including performance test reports, and excess emissions reports, required to be submitted by industry

. Audit facility

records. Input, analy

ze, and maintain data in the AIRS Facility S ubs ys tem (AFS). 5(b) Collection Methodology and Management Following notification of startup, the reviewing authority might inspect the source to determine whether the pollution control devices are properly installed and operated. Performance test reports are used by the Agency

to discern a source ’ s initial capability to comply

with the emission standard and note the operating conditions under which compliance was achieved. Data and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs. The semiannual reports are used for problem identification, as a chec k on source operation and maintenance, and for compliance determinations.
In formation contained in the reports is entered into the AFS which is ope rated and maintained by the EPA’ s Office of Compliance. AFS is EPA ’ s database for the collection, maintenan ce and retrieval of compliance data for over 125,000 industrial and government

- owned facilities. EPA uses the AFS for tracking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices and EPA headquarters. EPA and its delegated Authorities can edit, store, retrieve and analy ze the data. The records required by this regulation must be retained by the owner or operator for two years. 5(c) Small Entity Flexibility There are no small businesses affected by this regulation at present, and no small businesses are expected to become subject to the regulation in the next three years. (64 FR 72057 , December 23, 1999 ). 5(d) Collection Schedule The specific frequency

for each information collection activity within th is request is shown below in Table 1: Annual Respondent Burden and Cost for NSPS for Sewage Sludge Treatment Plants (40 CFR part 60, subpart O) (Renewal)

6. Estimating the Burden and Cost of the Collection Table 1 documents the computation of individu al burdens for the recordkeeping and reporting requirements applicable to the industry for the subpart included in this I CR. The individual burdens are expressed under standardized headings believed to be consistent with the concept of burdens under the P aperwork Reduction Act. Where appropriate, specific tasks and major assumptions have been identified. Responses to this information collection are mandatory

. The Agency

may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it display s a currently valid OMB Control Number. 6(a) Estimating Respondent Burden The average annual burden to industry over the next three years from these recordkeeping and reporting requirements is estimated to be 12,464 (Tot al L abor Hours from Table 1). The recordkeeping hours , shown in Table 1 , are 2 , 097 .6 and the reporting requirement hours , also shown in Table 1 , are 10,366.3

. These hours are based on Agency studies and background documents from the development of the re gulation, Agency

knowledge and experience with the NSPS program, the previously approved I CR, and any comments received. 6(b) Estimating Respondent Costs (i) Estimating Labor Costs This I CR uses the following labor rates: Managerial $114.49 ($54.52 + 110%) Technical $98.20 ($46.76 + 110%) Clerical $48.53 ($23.11 + 110%) These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2009, “Table 2. Civilian Workers, by occupational and industry group.” The rates are from column 1,

“ Total compensation. ” The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry

. (ii) Estimati ng Capital/Startup and Operating and Maintenance Costs The ty pes of industry

cost associated with the information collection activities in the subject standard are both labor costs which are addressed elsewhere in this I CR and the costs associated with continuous monitoring. The capital/startup costs are one

- time cost wh en a facility becomes subject to the regulation. The annual operation and maintenance costs are the ongoing costs to maintain the monitors and other costs such as photocopying and postage.9 (ii i) Capital/Startup vs. Operati n g and Maintenance (O&M) Co sts

The total capital/startup costs for this I CR are $ 40 ,000. This is the total of column D in the above table. The total operatin g and maintenance (O&M) costs for this I CR are $ 3,92 0,000. This is the total of column G. The total respondent costs have been calculated as the addition of the capital/startup costs, and the annual operation and maintenance costs. The average annual cost for capital/startup and operation and maintenance cost to industry over the next three years of the I CR is estimated to be $ 3,96 0,000. All costs are considered recordkeeping costs. 6(c) Estimating Agency Burden and Cost The only costs to th e Agency

are those costs associated with analy sis of the reported information. EPA’ s overall compliance and enforcement program includes activities such as the examination of records maintained by

the respondents, periodic inspection of sources of emissio ns, and the publication and distribution of collected information. The average annual Agency cost during the three years of the I CR is estimated to be $ 94,999

. Details upon which this estimate is based appear below in Table 2: Annual Agency Burden and Co st for NSPS for Sewage Sludge Treatment Plant In cinerators (40 CFR part 60, subpart O) (Renewal)

. This cost is based on the average hourly labor rate as follows: Managerial $6 2.27 (GS

- 13, Step 5, $38. 92 + 60%) Technical $4 6

. 21 (GS

- 12, Step 1, $28. 88 + 6 0%) Clerical $2 5.01 (GS

- 6, Step 3, $15. 63 + 60%) These rates are from the Office of Personnel Management (OPM), 2010 General Schedule, which excludes locality rates of pay

. The rates have been increased by 60 % to account for the benefit packages availab le to government employees. Details upon which this estimate is based appear below in Ta ble 2: Annual Agency Burden and Cost for NSPS for Sewage Sludge Treatment Plants (40 CFR part 60 , subpart O ) (Renewal)

. 6(d) Estimating the Respondent Universe and T otal Burden and Costs Based on our research for this I CR, approximately 112 existing facilities are currently subject to the10

standard. It is estimated that no expected additional sources per year will become subject to the standard in the next three year s. Number of respondents is calculated using the following table which addresses the three years covered by

this I CR.

Total Annual Responses Total 226 (rounded) The number of Total Annual Responses is 226

. The total annual labor costs are $ 1,178,948 . Details regarding these estimates may be found below in Table 1 : Annual Respondent Burden and Cost for NSPS for Sewage Sludge Treatment Plants (40 CFR part 60, subpart O) (Renewal)

. Note that the total annual capital and O&M costs to the regulated entity are $ 3,96 0,000 . These costs are detailed in Section 6(b)(iii ), Capital/Startup vs. Operating and Maintenance (O&M) C osts. 6(e) Bottom Line Burden Hours Burden Hours and Cost Tables The detailed bottom line burden hours and cost calculations for the respondents and the Agency are shown in Tables 1 and 2 below, respectively , and summarized below.

(i) Respondent Tall y The total annual labor hours are 12,464 . Details regarding these estimates may be found below in Table 1 : Annual Respondent Burden and Cost for NSPS for Sewage Sludge Treatment Plants (40 CFR part 60, subpart O) (Renewal)

. Furthermore, the annual publi c reporting and recordkeeping burden for this collection of information is estimated to average 55 hours (rounded) per response.

(ii) The Agency Tally The average annual Agency burden and cost over next three years is estimated to be 2,097 labor hours at a cost of $ 94,999 . See below Table 2 : Annual Agency Burden and Cost for NSPS for Sewage Sludge Treatment Plants (40 CFR part 60, subpart O ) (Renewal)

. 6(f) Reasons for Change in Burden There is an increase in the total estimated burden as currently id entified in the OMB Inventory of Approved Burdens which is due to more accurate estimates of existing sources. T he number of existing facilities changed from 54 to 112 and increased the number of responses, burden hours, labor costs, and O&M costs. A red

uction in capital/start

- up costs occurred due to the decrease of anticipated new sources which declined from 1 to 0.4 new sources per year. 6(g) Burden Statement The annual public reporting and recordkeeping burden for this collection of information is estimated to average 55 hours per response (rounded) . 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 ne eded to review instructions; develop, acquire, install, and utilize technology

and sy stems for the purposes of collecting, validating, and verify ing information, processing and maintaining information, and disclosing and providing information; adjust the e xisting way s to comply with12

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 dis close the information. An agency

may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it display s a valid OMB Control Number. The OMB Control Numbers for EPA ’ s regulations are listed at 40 CFR part 9 and 48 CFR chapter 15.
