_________________________________________________________________ ____________ _ Supporting Statement Revisions to Ambient Air Monitoring Regulations for Ozone

EPA ICR # 0940

PART A

1. Identification of the Information Collection

(a) Title of the Information Collection

“ Revisions to Ambient Air Monitoring Regulations for Ozone ( Proposed Rule) ”

(b) Short Characterization/Abstract

This Information Collection Request (ICR) includes ambient air monitoring data reporting and recordkeeping activities associated with the 40 CFR part 58 Ambient Air Quality Surveillance regulations. These data and information are collected by State, local , and Tribal air quality management agencies and reported to the U.S. Environmental Protection Agency (EPA).

As part of the Ozone NAAQS proposed rulemaking, EPA is proposing revisions to the length of the required O 3 monitoring season (see section VI ) of the preamble) . Unlike the ambient monitoring requirements for other criteria pollutants that mandate year

- round monitoring, the currently required O 3 monitoring seasons vary in length due to the dependence of

ozone

- forming photochemical activity on se asonally

- dependent factors such as ambient temperature, strength of ins u lation, and length of day. The changes in the proposed rule affect the following states by changing the length of the required ozone season by the listed number of

months:

 Add one mo nth (Connecticut, Delaware, District of Columbia, Idaho, Illinois, Iowa, Kansas, Maryland, Massachusetts, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Texas (northern portion), Virginia , West Virginia )

 Add two months, ( Indiana, Michigan, Montana, North Dakota, Wyoming )

 Add four months (Florida , South Dakota )

 Add five months (Colorado)

 Add seven months (Utah)

 Add 1

. 5 months (Wisconsin)

Additionally, O 3 monitors at NCore stations currently operate on a year

- round basis, i.e., January to December , regardless of the length of the required O 3 season for the state in which the

NCore station is located

. EPA is proposing that the length of the ozone monitorin g season for NCore be year round.2

O 3 monitors will be required to operate according to the revised monitoring season requirements effective January 1, 201 7 , or the first day of the required monitoring season in

201 7

.

The EPA is also proposing changes to the PAMS network design and method collection requirements. The EPA recognizes that the proposed changes to the PAMS requirement will require resources and a reasonable implementation schedule if they are promulgated. The implementation of these changes, if finalized, will occur beyond the time frame of this ICR with likely implementation dates between late 2017 and 2019, depending on the resulting schedule of any mandatory O 3 designations triggered if the level of the O 3 NAAQS is revised. Accordingly,

t he cost estimates for the PAMS network (including proposed revisions) will be captured in

future routine update s to the Ambient Air Surveillance ICR that are required every 3 years by the Office of Management and Budget

. At this time, the EPA believes tha t the current national funding level of the PAMS program is sufficient to support these proposed changes, especially in light of the staggered compliance schedule described above. An additional discussion of PAMS funding issues is included in section VI.C of the O 3 NAAQS preamble.

.

EPA and others (e.g., State, local, and Tribal air quality management agencies, environmental groups, academic institutions, and industrial groups) use ambient monitoring data for many purposes. Some of the more prominent uses include informing the public and other interested parties of an area ' s air quality, judging an area ' s (e.g., county, city, neighborhood) air quality in comparison with the established health or welfare standards (including both national

and local standard s), evaluating an air quality management agency ' s progress in achieving or maintaining air pollutant levels below the national and local standards, developing and revising State Implementation Plans (SIPs) in accordance with 40 CFR part 51, evaluating air pollutant control strategies, developing or revising national control policies, providing data for air quality model development and validation, supporting enforcement actions, documenting episodes and initiating episode controls, air quality trends assess ment, and air pollution research.

The State, local, and tribal air quality management agencies with responsibility for reporting ambient air quality data and information as requested in this ICR submit these data electronically to the EPA ' s Air Quality Sy stem (AQS) and AIRNow databases. Quality assurance/quality control records and monitoring network documentation are also maintained by each State, local, and Tribal agency, in AQS electronic format where possible.

Although the State, local, and Tribal a ir quality management agencies are responsible for the operation of the air monitoring networks, the EPA funds a portion of the total costs through federal grants. Some of these grants require an appropriate level of contribution, or match from

the State/ local air quality management agencies. The costs shown in this ICR are the total costs incurred for the monitoring program regardless of the source of the funding.

For the purpose of this ICR, the burden figures represent the burden estimate based on the requirements contained in the proposed rule. The burden estimates are for the 3

- year period of

201 5 through 201 7 . ICR bur den estimates are associated with the current O 3 monitoring portion

of ICR # 0940 (2060

- 0084)

.3

This Information Collection is estimated to involve 1 5 8 respondents for a total average cost of approximat ely $ 2 4

, 115

, 182 (total capital, and labor and operation and maintenance) plus a total burden of 3 3 9

, 930 hours for the support of all operational aspec ts of the entire ozone monitoring network . The labor costs associated with these hours are $ 19

, 813 ,6 92 . Also included in the total are other costs of operations and maintenance of $ 2,2 10 ,1 32 and equipment and contract costs of $ 2,0 9 1, 358

. EPA typically funds 60 percent of the $2 4

, 115

, 182 through grants to the State/local agencies. In addition to the costs at the State, local, and Tribal air quality management agencies, there is a burden to EPA of 41,418 hours and $ 2,617,591

.

The actual labor cost inc rease associated with the proposed changes to the ozone monitoring season is $1, 668

, 433 from the previously approved ICR

.

2. Need for and Use of the Collection

(a) Need/Authority for the Collection

The information requirements included within this ICR are necessary to provide the EPA with ambient air quality surveillance data to determine the United States ' air quality status, to make attainment decisions with respect to the NAAQS, to assist in developing necessary control strategies to ensure attainme nt of the NAAQS, to assess national trends in air pollution, to inform the public of air quality, and to determine the population ' s exposure to various ambient air pollutants. The EPA ' s goal of attaining the NAAQS in all areas of the United States is dire ctly dependent upon the availability of ambient air quality data requested in this information collection. Additionally, the EPA, State, local, and Tribal air quality management agencies, environmental groups, industrial groups, and academic organizations use these data to study atmospheric chemistry, e.g., the formation of O 3 , to determine the most appropriate and effective control strategies necessary to reduce air pollution.

The principal legal authority for this information collection is the Clean Air Act 42

U.S.C.A. §§ 7403, 7410, and 7511a, from which the 40 CFR part 58 regulations were promulgated.

Under § 7403 (c), the Administrator is required to conduct a program of research, testing, and development of methods for sampling, measurement, monitor ing, analysis, and modeling of air pollutants, specifically including a requirement to establish a national network to monitor, collect, and compile data with quantification of certainty in the status and trends of air emissions and air quality. This prog ram will also include the development of improved methods and technologies to increase understanding of the sources of O 3 precursors, O 3 formation, O 3 transport, regional influences on urban O 3 , regional O 3 trends, and interactions of O 3 with other polluta nts.

Section 7410 (a) contains the SIP requirements, which include a requirement that each State submit a SIP that provides for the establishment and operation of appropriate devices, methods, systems, and procedures necessary to monitor, compile, analy ze, and make available to the Administrator data on ambient air quality.4

Section 7511a (c)(1) states that the Administrator will promulgate rules requiring that State, local, and Tribal air quality management agencies conduct enhanced monitoring of O 3 a nd its precursors (oxides of nitrogen and volatile organic compounds) in serious, severe, or extreme

O 3 nonattainment areas.

2(b) Practical Utility/Users of the Data

The EPA Office of Air Quality Planning and Standards (OAQPS) uses the ambient air quality data included within this collection to make attainment decisions with respect to each air pollutant subject to NAAQS. For those areas that do not attain the NAAQS for one or more pollutants, the OAQPS, the affected EPA Regional Office, and the af fected State or local air quality management agency will work to develop an appropriate SIP to address how the area ' s air quality can be improved to meet the applicable NAAQS.

To identify how the nation is progressing in improving air quality, the OAQPS p repares annually the National Air Quality and Emissions Trends report (http://www.epa.gov/airtrends) using the ambient air quality data collected through this ICR. The State, local, and Tribal air quality management agencies use these data for multiple pu rposes including tracking their progress toward achieving and maintaining air quality within the established NAAQS and any statewide standards they have established. For example, the State of California has established a separate statewide O 3 air quality standard that is more stringent than the NAAQS for O 3 ; therefore, they use ambient air data to determine compliance with both standards.

3. NON

- DUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA

3(a) Non

- duplication

This collection is not unnecessarily duplicative of information otherwise reasonably accessible to the agency. The AQS and AIRN ow systems, which contain information based solely on this collection, are the only national air quality data repositories available to the EPA.

The a mbient air quality surveillance data and related information collected through this information collection are not otherwise reasonably accessible to the EPA.

A few State and local air quality management agencies have their own data storage systems (e.g., the California Air Resources Board); however, most State, local, and Tribal air quality management agencies use the AQS and AIRNow as their primary repositories for all air quality data.

3(b) Public Notice Required Prior to ICR Submission to OMB

The 19 95 Paperwork Reduction Act requires that any agency developing a non

- rule related ICR must solicit public comments for a 60

- day period prior to submitting the ICR to

OMB. This section is not applicable to this ICR because this is a r ule

- related ICR.

3(c) Consultations5

Through the course of planning, monitoring, and improving upon this collection and its associated regulation, the EPA regularly consults with affected State, local, and Tribal air quality management agencies throug h various methods including the regulatory process, regular meetings, and training courses. The EPA routinely conducts workshops and training on the AQS reporting system . The EPA Regional Offices conduct annual ambient air monitoring meetings

with their affected State, local, and Tribal air quality management agencies to assist these affected agencies with this collection and its a ssociated regulation. The EPA’s OAQPS also

meets regularly with leading State and local air monitoring managers to discuss th e N ation’s ambient air monitoring program and this collection, via large monthly phone calls and smaller in person meeting s two or three times per year. Key advisory committees include the Monitoring Steering Committee of NACAA (National Association of Cl ean Air Agencies) and the Ambient Monitoring & Methods Subcommittee (AMMS) of CASAC. EPA meets with these committees on a regular basis to exchange information on ambient monitoring requirements.

3(d) Effects of Less Frequent Collection

State, local, and Tribal air quality management agencies would collect and report ambient air quality data without the 40 CFR 58 regulation associated with this collection. Sanctions do not automatically accrue to State or local air quality management agencies that fai l to meet these requirements. The 40 CFR part 58 regulations and this associated collection do provide for a consistent system for reporting and record keeping that would not exist without these requirements. The effects of less frequent collection inclu de:

• A national database that is not consistently updated and available for public consumption;

• Less timely attainment designations with respect to the NAAQS;

• More difficulty in identifying and repairing problems with an ambient air monitor

-- i.e ., data are used to check a monitor’s operating condition, and reporting data less frequently would delay a State or local agency’s ability to recognize a problem with a monitor or a laboratory procedure; and

• The EPA would not be able to consistently a nswer questions from the public in a timely fashion regarding air quality in various areas of the country.

3(e) General Guidelines

All of the OMB ' s general guidelines for information collections in 5 CFR 1320.6 are met by this ICR. None of the guidelines are exceeded.

• Data reporting on a quarterly basis is the requirement. Nearly all respondents voluntarily report on a monthly basis.

• Record retention is for no more than 3 years (most records are kept by the EPA data reposit ory, not the affected State, local, and Tribal air quality management agencies)6

• Information is maintained and reported in the standardized electronic AQS format.

3(f) Confidentiality

Information that is considered personal, private, proprietary, or confidential is not required for this collection. One purpose of collecting ambient air data through AQS and AIRNow is to inform the public of general air quality in ambient air (air considered generally accessible to the public), and as such, does not pr esent a need for maintaining a confidential nature. Security measures are taken to prevent tampering with the AQS electronic database by limiting the access to the AQS mainframe only to authorized users

3(g) Sensitive Questions

T his section is not applicable to this ICR because no information involving matters of a

sensitive nature is collected.

4. THE RESPONDENTS AND THE INFORMATION REQUESTED

4(a) Respondents/SIC Codes

This ICR affects State, local, and Tribal governments (S IC code 951, Administration of Environmental Quality Program) that are currently operating and maintaining established ambient air quality networks. The 40 CFR part 58 regulations associated with this request require that State, local, and Tribal air qual ity management agencies conduct the ambient air quality surveillance and report the data to the EPA ' s AQS. Although industrial, environmental, and research organizations may use the data available through the AQS, they are not required to report any infor mation for this information collection. Data submittal to AIRNow is voluntary for all organizations, but most State

, local and Tribal agencies reporting to AQS also report to

AIRNow.

4(b) Information Requested

(i) Data items, including record keeping requirements

These data items are submitted electronically to EPA ' s AQS as required by 40 CFR part

58. Th e se data are stored electronically within the EPA ' s AQS, and separate records kept by the State or local air quality management agency are not required

.

• Hourly ambient air pollutant concentrations of O 3 collected at SLAMS / PAMS and

tribal sites.

• Ozone precursor and meteorological data collected at PAMS.

• Precision and accuracy data for all SLAMS sites, PAMS, and Special Purpose

Monitors (SPM).7

• SLAMS monitoring network description information, including the site AQS identification number, site location, sampling and analysis method, operating schedule, monitoring objective, site ' s scale of representation, identity of the urban

area repr esented, and quality assurance plan.

• PAMS network description which includes an implementation schedule, identification of the monitoring area represented, AQS site identification number, site location, site type, sampling and analysis method, operating schedule, and an O 3 event forecasting scheme, if appropriate.

• Results of the annual ambient air monitoring network and quality assurance plan

review.

( ii) Respondent Activities

A model respondent would engage in the following activities to comply wi th this information request:

• Read the 40 CFR part 58 regulatory provisions and other EPA guidance (for example, please reference our Internet site at www.epa.gov/ttn/amtic.)

• Plan ambient air monitoring activities, such as developing a quality assurance plan for the network operation and maintenance, developing and reviewing the ambient air quality surveillance network design, planning where to locate sites, plan ning how to maintain and operate each site, develop ing a data reporting and validati on plan.

• Write the quality assurance plan for network operation and maintenance, the ambient air quality surveillance network plan, and the data reporting and validation plan. Submit these plans to the EPA Regional or Headquarters office for review, an d approval if appropriate.

• Obtain on

- site leases or agreements to locate ambient air quality surveillance equipment.

• Investigate vendors, and procure equipment necessary to meet the ambient air quality network plan.

• Receive training for site operation and maintenance, quality assurance procedures, and data processing and reporting.

• Make arrangements for appropriate utility hookups for each ambient air quality surveillance site, i.e., electricity, telephones, data lines for electronic submis sion of concentrations from automated analyzers.8

• Install ambient air quality surveillance equipment and equipment shelter. Ensure security of the site.

• Conduct ambient air quality monitoring, incorporating all appropriate quality assurance procedure s such as calibrations, precision and accuracy checks, and, if necessary, concurrent monitoring.

• Validate the ambient air data for quality assurance considerations.

• Electronically submit the complete and validated ambient air data to the AQS and/or

A IRNow data repositories.

• Prepare and submit to EPA annually the SLAMS sites summary report.

Each of these activities are conducted using existing reporting and recordkeeping practices, including electronic submittal to the AQS and to AIRNow . If the 40 CFR part 58 regulations did not exist, and presumably the related AQS and AIRNow, the quality assurance procedures, and the siting guidance did not exist, the State, local, and Tribal air quality management agencies would in a majority of cases conduct monitoring; however, methods used by each agency would vary and data would not be readily available to EPA and the public. The influence of the 40 CFR part 58 regulations has been to provide a nationally consistent mechanism for collecting ambient air qu ality data including uniform quality assurance procedures, data collection and storage mediums (AQS), and uniform methodology. Without

th ese regulations and associated ICR s , managing and maintaining a national air quality program would be extremely diffic ult, if possible.

5. THE INFORMATION COLLECTED

-- AGENCY ACTIVITIES, COLLECTION METHODOLOGY, AND INFORMATION MANAGEMENT

5(a) Agency Activities

The EPA conducts the following activities to implement this ICR and associated regulation:

• Periodically review the 40 CFR part 58 regulations to update the information collection and monitoring requirements in light of new technological developments or new air pollutant standards. Develop revisions to the regulations in response to legislative action and pr ogram changes.

• Establish, maintain, and support the AQS and AIRNow as the national repositories for all State, local, and Tribal air quality management agency ambient air quality data and monitoring information. Periodically evaluate and improve upon t his system as new technologies, and new regulatory requirements would dictate.9

• Answer respondent (generally State, local, and Tribal air quality management agencies, but also industrial organizations, environmental groups, and others) questions about am bient air monitoring, the 40 CFR part 58 regulatory requirements, and the AQS and AIRNow. This includes the establishment of the Ambient Monitoring Technology Information Center bulletin board, the AQS toll

- free hotline,

and other written or verbal commun ication.

• Support the quality assurance program by working within the EPA and with the respondents to evaluate precision and accuracy data, oversee the National Performance Audit Program, participate in systems audits, and conduct data

validation checks on the AQS data submittal.

• Provide within the AQS mechanisms for statistical calculations, such as the number of times a particular ambient air quality monitoring site exceeds the NAAQS. Distribute the AQS data in various ways including upon written re quest, by Freedom of Information Act request, by press release, and in the annual National Air Quality and Emissions Trends Report.

• Provide adequate electronic storage space within the AQS for all ambient air quality

surveillance data and information.

• Provide various reports and graphics for users of AIRNow.

5(b) Collection Methodology and Management

All State, local, and Tribal ambient air monitoring networks have access to and use well

established quality assurance procedures as defined in the Quality Assurance Handbook for Air Pollution Measurement Systems, Volumes I and II, EPA/600/R

- 94/038a & b. These documents ensure that all ambient air quality data are accurate and reliable.

The EPA has provided and will continue to provide resources for the maintenance and operation of the AQS and AIRNow national data repositories. All data required by thi s collection are submitted electronically to reduce the burden of the collection and to improve data quality, agency efficiency, and responsiveness to the public. Various statistical and graphical summaries are also provided by the AQS and AIRNow systems which enhance the utility of the information for consumption by the public and all affected State, local, and Tribal air quality management agencies. In submitting ambient air data into the AQS and AIRNow national repositories, we ensure that the data are publicly available, electronically stored, and electronically retrievable. State, local, and Tribal air quality management agencies and the EPA have been submitting data to the AQS since its inception in 1987.

5(c) Small Entity Flexibility

--

This collection contains a minimum amount of information in order to manage the air quality program for the United States. The smallest entities affected by this collection are local10

air quality management agencies, typically consisting of the governing a gencies for a county or group of counties, or a smaller metropolitan area (e.g., cities with a population of 100,000). This collection reduces to the extent practicable and appropriate the burden on entities that provide ambient air quality data and infor mation to or for the EPA, including with respect to small entities, as defined in the Regulatory Flexibility Act (5 U.S.C. 601(6)), the use of such techniques as:

• Establishing differing compliance or reporting requirements or timetables that

account for the resources available to those who are to respond (e.g., the monitoring and reporting requirements decrease as the population of an area decreases, and various timetables for deploying ambient air monitoring stations are negotiated

between the affected State

, local or Tribal air quality management agency and the EPA with consideration of the respondent ' s resources);

• Clarification, consolidation, or simplification of compliance and reporting requirements (e.g., by establishing, maintaining, and impro ving as needed the AQS and AIRNow national repositories for ambient air quality data and information);

• Exemption from coverage of the collection of information, or any part thereof (e.g., the EPA negotiates with State, local, and Tribal air quality mana gement agencies to determine the most effective and most efficient ambient air quality networks with respect to the monitoring needs, technical abilities, and resources available to each affected agency).

5(d) Collection Schedule

Ambient air quality sur veillance data and precision and accuracy data for criteria air pollutants are submitted according to the schedule defined in 40 CFR 58.16. These current regulations require that State and local air quality management agencies report their data within

90 days after the end of the quarter during which the data were collected. Ambient data are certified on annual basis by a deadline of May 1 of each year for the previous calendar year.

The annual air quality surveillance network reviews are conducted and reports are submitted to the EPA on a schedule that is determined by the affected State or local air quality management agency and the EPA Regional Office.

Ambient air quality data an d information are made available to the public at any time in various ways, including:

• Upon request to the appropriate EPA Regional office, or to the OAQPS;

• By Freedom of Information Act Request to the appropriate EPA Regional Office or the OAQPS;

• From the State or local air quality management agency responsible for collecting the ambient air quality data and information;11

• By obtaining access, through appropriate EPA channels, to the AQS and AIRNow to obtain the data electronically;

• Through EPA public reports, such as the annual National Air Quality and Emissions Trends Report; or

• Through the AIRNow data base and the AQI reporting mechanisms which include newspaper, television, Internet and other publicly available notices (see

www.epa.gov /airnow).

6. ESTIMATING THE BURDEN AND COST OF THE COLLECTION

6(a) Estimating Respondent Burden

All activities listed with section 4 (b) (ii) of this ICR Supporting Statement are presented in Worksheet 1. The detailed burden and cost estimates for the different types of monitors are based on information provided in the updated version of Guidance f or Estimating Ambient Air Monitoring Costs for Criteria Pollutants and Selected Air Toxic Pollutants (prepared by Desert Research Institute for the EPA Office of Air Quality Planning and Standards, Air Quality Assessment Division, Ambient Air Monitoring Gr oup, January 2005). The cost estimates presented in this guidance document are based on existing literature and direct monitoring experience. The costs for equipment and supplies were verified with vendors. The monitoring costs are based on vendor quote s for the monitor type that EPA expects respondents to use to comply with the requirements

. Costs for level of effort estimates are verified with selected State and local agencies. All cost values presented in the guidance document are adjusted to 2004

d ollars, based on the average of the first two quarters.

For use in preparing the burden estimates for this ICR, costs for the monitoring requirements were inflated to 201 5 , 201 6 , and 201 7

. The cost escalation factors were estimated based on the approp riate Gross Domestic Product (GDP) price indices. Tables showing the detailed burden estimate calculations are presented below . A summary of the average annual respondent burden costs follows.

Surveillance."

6(g) Burden Statement

The annual public repor ting and recordkeeping burden for this collection of information is estimated to average 31 hours per response

. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide informati on 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 informatio n, and disclosing and providing information; adjust the existing ways to comply with 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 disclose the information. 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 are listed in 40 CFR part 9 and 48 CFR chapter 15.
