SUPPORTING STATEMENT FOR
EPA ICR NUMBER 1813.09,
RENEWAL OF THE ICR FOR THE REGIONAL HAZE REGULATIONS
EPA # 1813.09
Executive Summary
Draft 05/01/06
The change in burden reflects changes in labor rates, changes in the activities conducted due to the normal progression of the program, and the fact that the states will be shifting their primary focus to development of interim progress reports required by the regional haze rule and to development of periodic comprehensive SIP revisions due in 2018 (and, for 2 states, development of initial SIPs).

of the Information Collection
1.2 Description
Subpart P of 40 CFR 51, Protection of Visibility, also known as the regional haze rule, is the subject of this clearance request. In the next three years, activities conducted by the states, Federal Land Managers (FLMs), and the EPA will focus on submitting SIP revisions and progress reports for regional haze. 40 CFR 51.308 (f) requires states to develop regional haze implementation plan revisions evaluating and reassessing reasonable progress goals, calculations of baseline and natural visibility conditions, the long-term strategy, the monitoring strategy and other implementation plan requirements. There are similar reporting requirements under 40 CFR 51.309, a section of the regional haze rule in which three states (Utah, Wyoming, and New Mexico) elected to submit their SIPs. Under section 309, these states adopted regional haze strategies for the period from 2003 to 2018 for sulfur dioxide emissions. These strategies are based on recommendations from the Grand Canyon Visibility Transport Commission (GCVTC) for protecting the 16 Class I areas in the Colorado Plateau area. During the next three years, fourteen states will also be responsible for submitting progress reports. 40 CFR 51.308 (g) requires states to develop periodic reports evaluating progress towards the reasonable progress goals for improving visibility in Class I areas inside the state and in neighboring states, and 40 CFR 51.309(d)(10) requires similar actions on the part of the 3 states that submitted regional haze SIPs under 40 CFR 51.309.
Under the 1999 regional haze rule, states are required to set periodic goals for improving visibility in the 156 Mandatory Class I Federal Areas. As states work to reach these goals, they must develop regional haze implementation plans that contain enforceable measures and strategies for reducing visibility-impairing pollution. States were required to develop their initial implementation plans by December, 2007. Periodic comprehensive revisions to implementation plans are due July 31, 2018 and every 10 years thereafter.
The primary focus for estimating burden for this 3 year renewal period (March 31, 2016 – March 31, 2019) will apply to the next program milestone which are the periodic comprehensive SIP revisions due in July 2018 (see 40 CFR 51.308(f)) for all states, including those covered under 40 CFR 51.309. In addition, 2 states have still yet to submit the first SIPs due December 17, 2007 (see 40 CFR 51.308(b)). In the 5-year progress report required by 11 states during this 3 year renewal period, those states are required to describe the status of the implementation of measures needed to achieve reasonable progress goals, report on the emissions reductions achieved, assess visibility changes, and evaluate whether the current implementation plan is sufficient to meet all established reasonable progress goals. Similar progress report requirements apply to the 3 states covered under 40 CFR 51.309.
2.1 Need / Authority for the Collection
2 Need and Use of the
Collection
are triggered by a FLM. The regional haze rule, promulgated in 1999, added new sections to the code of federal environmental regulations. These included sections 40 CFR 51.308 and 40 CFR 51.309. This ICR renewal request provides for continued implementation of the regional raze rule. During this clearance period, we anticipate that the reporting requirements under 40 CFR 51.308(f) and (g) will be the major program focus along with the similar reporting requirements (see 40 CFR 51.309(d)(10)) for the three states that submitted regional haze SIPs under 40 CFR 51.309 (and for 2 states, the reporting requirements for the first SIPs under 40 CFR 51.308(b)).
2.2 Practical Utility / Users of the
Data
2.3 Caveats and Considerations
Throughout this ICR, the reader will observe estimated values that show accuracy to the single hour or dollar. However, reporting values at the single unit level can be misleading. In most situations, the proper way to present estimated data would be to determine an appropriate level of precision and truncate values accordingly, usually in terms of thousands or millions of units. For instance, a spreadsheet generated estimation of $5,456,295 could be presented in the text as $5.5 (millions) or $5,456 (thousands). One problem with such an approach is the loss of data richness when the report contains a mixture of very large and very small numbers. Consequently, to avoid the loss of information through rounding, this ICR reports all values at the single unit level and reminds the reader that there is no implied precision inherent in this style of reporting.
3.1 Non-Duplication
3 Non-Duplication, Consultation, and
Other Collection Criteria
3.2 Public Notice Requirements
The ICR for the regional haze rule was revised last in March 2013. We
solicited public comments on this ICR prior to submitting it to OMB. We
issued a Federal Register notice requesting comments on the ICR renewal
on September 29, 2015 (80 FR 58473) and provided a 60-day public notice and comment period. The EPA received no comments during the comment period.

Mr. David Healy of the New Hampshire Department of Environmental Services responded and agreed with the estimates of burden on potential respondents, with the caveat that it could take somewhat longer than 500 hours for a state to prepare periodic comprehensive SIP revisions in some circumstances, especially for a state that contains one or more Class I Federal areas. The EPA received no other responses to its solicitation for consultations.
3.4 Less Frequent Collection
The information collection requested under this ICR is necessary to ensure implementation of the 40 CFR 51.308 and 40 CFR 51.309 requirements.
3.5 General Guidelines
OMB's general guidelines for information collections must be adhered to by all federal agencies for approval of any rulemaking's collection methodology. In accordance with the requirements of 5 CFR 1320.5, the Agency believes:
The regional haze regulations do not require periodic reporting more frequently than every 5 years.
The regional haze regulations do not require respondents to participate in any statistical survey.
Written responses to Agency inquiries are not required to be submitted in less than 30 days.
Respondents do not receive remuneration for the preparation of reports required by the Act or part 51.
To the greatest extent possible, the Agency has taken advantage of automated methods of reporting.
The recordkeeping and reporting requirements contained in the current regional haze program and the changes proposed in this rulemaking do not exceed any of the Paperwork Reduction Act guidelines contained in 5 CFR 1320.5, except for the guideline which limits retention of records by respondents to 3 years. The Act requires both respondents and state or local agencies to retain records for a period of 5 years. The justification for this exception is found in 28 U.S.C. 2462, which specifies 5 years as the general statute of limitations for federal claims in response to violations by regulated entities. The decision in U.S. v. Conoco, Inc., No. 83-1916-E (W.D. Okla., January 23, 1984) found that the 5-year general statute of limitations applied to the CAA.
3.6 Confidentiality
Confidentiality is not an issue for this rulemaking. In accordance with the Clean Air Act Amendments of 1990, any monitoring information to be submitted by sources is a matter of public record. To the extent that the information required is proprietary, confidential, or of a nature that could impair the ability of the source to maintain its market position, that information is collected and handled subject to the requirements of §503(e) and §114(c) of the Act. Information received and identified by owners or operators as confidential business information (CBI) and approved as CBI by EPA, in accordance with Title 40, Chapter 1, Part 2, Subpart B, shall be maintained appropriately (see 40 CFR 2; 41 FR 36902, September 1, 1976; amended by 43 FR 39999, September 8, 1978; 43 FR 42251, September 28, 1978; 44 FR 17674, March 23, 1979).

5 The Information Collected - Agency
Activities, Collection Methodologies, and Information Management
5.1 Agency Activities
FLMs. The FLMs will be reviewing the progress reports, the periodic comprehensive regional haze SIP revisions, and offering comments to the states in fulfillment of the requirement under 40 CFR 51.308(i)(4) for the states to coordinate their regional haze efforts with the FLMs.
5.2 Collection
Methodology and Management
The Agency believes the time necessary to perform a task is independent of the origins of its labor. For example, if a source would employ 20 hours of burden to fully perform a function, then a contractor hired by the source would also take 20 hours to perform that same task. Furthermore, the Agency assumes no economies or diseconomies of scale. The linear combination of any amount of contractor and source effort will also sum to 20 hours. Therefore, the burden estimates in this ICR act as an accurate assessment of the total burden to respondents.
For some burden categories, the Agency believes the hours assigned to them will be divided between the source and outside contractors. For these categories, the Agency established a composite cost per hour by developing a weighted average of the source and contractor wages, with the weight defined by the percentage of total effort each burden source applied. Consequently, the cost developed in this ICR should be interpreted as an upper bound on the actual cost of administration by the source. The methodology for determining cost per hour can be found in greater detail in section 6.2, below.
While this ICR renewal estimates burden to federal and state agencies, it does not include costs estimates to the industrial sources. This is because the effort for this ICR renewal period, March 31, 2016 through March 31, 2019 mainly involves preparation and review of the periodic comprehensive SIP revisions and progress reports required under CFR 51.308(f) and (g) and 51.309(d)(10) of the regional haze rule. Sources, for the most part, will not be involved in preparation of these reports.
The periodic comprehensive SIP revisions prepared by the states are due by July 31, 2018. The periodic comprehensive SIP revisions must at a minimum include the following elements (similar elements are required for the initial SIPs):
A summary of affirmation of, and revision to, reasonable progress goals, including determination of reasonableness of any additional measures that could be adopted to achieve the degree of visibility improvement projected by the analysis in the original SIP
A description of baseline and natural visibility conditions
An assessment of current visibility conditions and actual progress made toward natural conditions
Details on modeling conducted for the 2028 milestone
A summary of the effectiveness of, and re-development of, long term strategies
A description of the monitoring strategy
The progress reports prepared by the states are, in most cases, due five years after the state submits its comprehensive regional haze SIP. The progress reports must at a minimum include the following elements:
A description of the status of all measures included in the regional haze implementation plan for achieving reasonable progress.
A summary of the emissions reductions achieved throughout the state through implementation of the measures.
An assessment of the following visibility conditions and changes for each mandatory Class 1 Federal area within the state with values for most impaired and least impaired days expressed in terms of 5-year averages of the annual values: current visibility conditions for the most impaired and least impaired days; the difference between current visibility conditions for the most impaired and least impaired days and baseline visibility conditions; and the change in visibility impairment for the most impaired and least impaired days over the past 5 years.
An analysis tracking the change over the past 5 years in emissions of pollutants contributing to visibility impairment from all sources and activities within the state.
An assessment of any significant changes in anthropogenic emissions within or outside the state that have occurred over the past 5 years that have limited or impeded progress in reducing pollutant emissions and improving visibility.
An assessment of whether the current regional haze implementation plan elements and strategies are sufficient to enable the state, or other states with mandatory Class I Federal areas affected by emissions from the state, to meet all established reasonable progress goals.
A review of the state’s visibility monitoring strategy and any modifications to the strategy as necessary.
Other elements, including reporting, record keeping, and other measures, necessary to assess and report on visibility.
5.3 Small Entity Flexibility
The Regulatory Flexibility Act (RFA) requires regulatory agencies, upon regulatory action, to assess that action’s potential impact on small entities (businesses, governments, and small non-governmental organizations) and report the results of the assessments in (1) an Initial Regulatory Flexibility Analysis (IRFA), (2) a Final Regulatory Flexibility Analysis (FRFA), and (3) a Certification. For ICR approval, the Agency must demonstrate that it "has taken all practicable steps to develop separate and simplified requirements for small businesses and other small entities" (5 CFR 1320.6(h)). In addition, the agencies must assure through various mechanisms that small entities are given an opportunity to participate in the rulemaking process.
The EPA determined that it was not necessary to prepare a regulatory flexibility analysis in connection with the regional haze rule (July 6, 2005, 70 FR 39104) because the rule did not have a significant economic impact on a substantial number of small entities. Similarly, this ICR renewal will not impose any direct requirements on small entities and will apply primarily to states which are developing the SIP revisions.

All states (including those subject to a FIP) are required to develop and submit periodic comprehensive SIP revisions by July 31, 2018.
Two states are required to submit initial SIPs originally due December 17, 2007.
For the purposes of this ICR, we assume that each of these states will in fact submit progress reports and/or periodic comprehensive SIP revisions on the due dates indicated above, and the two states that still need to submit initial SIPs will do so before July 31, 2018.
6 Estimating the Burden and Cost of the
Collection
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 ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; and transmit or otherwise disclose the information. The burden estimate should be composed of (1) the total capital and start-up cost component annualized over its useful life; (2) the total operation, maintenance and purchases of services component. Each component should be divided into burden borne directly by the respondent and any services that are contracted out.
6.1 Estimating Respondent Burden
For three states (Utah, Wyoming, and New Mexico) which submitted their regional haze SIPs under section 309 of the regional haze rule, there are also 5-year periodic reporting requirements that are essentially the same as the requirements under section 308(g); the next due date for progress reports for these states is December 31, 2018. Table 6.1 summarizes the results for each of the major categories of respondents with details discussed in the narrative below.
Develop and Submit Progress Reports as required under the Regional Haze Rule. Based on the elements that are required for the report, which are described in section 5.2 above, we believe that an estimate of 280 hours per state to complete the 5-year progress report is reasonable. Much of the analysis for the report will entail the states assessing changes in their emission inventories for the reporting period and reporting on changes in visibility based on available monitoring data. This burden estimate does not include any hours for preparation and finalization of the emission inventories because it is assumed that the EPA will provide an approved inventory, with appropriate forward projections of future visibility conditions, which the states may use for their analyses. For each individual state, we believe that approximately 160 hours on average is needed to analyze, evaluate, and summarize changes in the inventory and monitoring data over the reporting period, and another 80 hours is sufficient to prepare the report in the form of a SIP revision. These estimates are based on informal conversations with state and the EPA’s technical staff. Finally, we assumed that states would need approximately 40 additional hours to address and respond to any public comments received on its SIP revision.
Develop and Submit Periodic Comprehensive SIP Revisions (or Initial SIPs) as required under the Regional Haze Rule. Based on the elements that are required for the periodic comprehensive SIP revisions (or initial SIPs), which are described in section 5.2 above, and a review of previous ICRs, we believe that an estimate of 500 hours per state to complete the periodic comprehensive SIP revision (or initial SIP) is reasonable.

6.2 Estimating Respondent Costs
Consistent with methodologies for previous NSR ICRs, the labor rate used to calculate federal, state, and local respondents’ labor costs is approximated from the 2015 federal government pay schedule. Managerial rates are accounted for by multiplying the hourly rate by 9%; the clerical support rates are multiplied by 13%.3 The hourly rate is $49.53, and the calculation is shown in Table 6.3

Since the purchase of capital equipment is believed to be an insignificant factor in meeting the requirements associated with this ICR renewal, the EPA assumes the operation, maintenance, or services are also negligible. Most of the data and other guidance for estimating emissions and visibility impacts are available in electronic form and any equipment needed to respond to requests will be part of the respondent’s operating inventory.
6.2.3 Annualized
Capital Costs
6.3 Estimating
Agency Burden and Cost
EPA Regional Offices. We assume that all 10 EPA Regional Offices will be responsible for reviewing progress reports and SIPs from the states in their jurisdiction, responding to public comments, and preparing federal register notices in taking final action on the SIPs.
EPA Headquarters. The EPA Headquarters staff will provide oversight and review of the submittals.
FLMs. The FLMs will review and comment on the submittals.
Table 6.4 presents our estimate of the Agency burden in the ICR clearance period which is the average to review one state plan. In developing these estimates, we considered previous estimates for similar activities, particularly related to the time necessary to review progress reports and SIPs and prepare federal register notices and respond to public comments.
For the progress reports, summing the total hours from Table 6.4 (360 hours) and multiplying by 14 total progress reports yields a total estimate of 5,040 hours. Using the calculated labor rate of $49.53/hr. from Table 6.3, multiplied by the 5,040 hours gives an estimated cost of $249,631, which when averaged over the 3 year collection period is about $83,210 per year as the Agency’s burden estimate for the progress reports.
For the periodic comprehensive SIP revisions, summing the total hours from Table 6.4 (400 hours) and multiplying by 54 total periodic comprehensive SIP revisions (or initial SIPs) yields a total estimate of 21,600 hours. Using the calculated labor rate of $49.53/hr, from Table 6.3, multiplied by the 21,600 hours gives an estimated cost of $1,069,848, which when averaged over the 3 year collection period is about $356,616 per year as the Agency’s burden estimate for the periodic comprehensive SIP revisions or initial SIPs.

6.4 Estimating the Respondent Universe
States. We assume that 50 states, the District of Columbia, and the U.S. Virgin Islands will develop and submit the periodic comprehensive regional haze SIP revision required in 2018. We assume that 14 states will be affected by the regional haze rule 5-year progress reporting requirements.
Tribes. No tribes have elected to develop and implement the regional haze plan.
Industry. The sole regional haze requirements for this reporting period are for the states to submit periodic progress reports and periodic comprehensive SIP revisions, and thus there is no anticipated burden for industrial sources.
