IDENTIFICATION OF THE INFORMATION COLLECTION 1( a) Title of the Information Collection ICR: Baseline Standards and Best Management Practices for the Coal Mining Point Source Category  Coal Remining Subcategory and Western Alkaline Coal Mining Subcategory ( Renewal) ( EPA ICR No. 1944.03; OMB Control Number 2040 0239).

1( b) Short Characterization/ Abstract The U. S. Environmental Protection Agency ( EPA) amended wastewater regulations for the Coal Mining Point Source Category ( 40 CFR Part 434) on January 23, 2002. The final rule established two new subcategories: one that addresses pre existing discharges at coal remining operations and a second that addresses drainage from coal mining reclamation and other nonprocess areas in the arid and semi arid western United States. The new subcategories created a set of standards and requirements for the specific waste streams defined in the final regulation. The new subcategories did not otherwise change the existing regulations.

This Information Collection Request ( ICR) presents estimates of the burden and costs to the regulated community over a 3 year period ( approximately 234 coal remining sites and 46 western alkaline surface coal mining sites) and 10 National Pollutant Discharge Elimination System ( NPDES) permit authorities for data collection and record keeping associated with modeling, implementation of best management practices, baseline monitoring, and performance monitoring requirements. An initial ICR was published on August 23, 2001 ( EPA ICR No. 1944.02 and OMB Control Number 2040 0239). This document is a renewal ICR.

Coal Remining Subcategory EPA established the new Coal Remining Subcategory to reduce severe and extensive damage resulting from abandoned mine lands. Acid mine drainage from abandoned coal mines is the number one water quality problem in Appalachian states. There are approximately 1.1 million acres of abandoned coal mine lands, over 9,000 miles of streams polluted by acid mine drainage, and many miles of dangerous embankments, highwalls, and surface impoundments in the Appalachian and mid continent coal regions of the U. S. Prior to 1977, reclamation of mine lands was not a federal requirement. Consequently, many coal mines have been abandoned, and they continue to degrade the environment and pose health and safety risks.

In addition to posing severe environmental and safety problems, abandoned mine lands may contain significant quantities of coal. Modern surface mining techniques now provide operators with a more economical means of " remining," thus enabling them to extract remaining coal reserves. During remining operations, many of the problems associated with abandoned mine lands are mitigated, because the operator becomes responsible for reclaiming the abandoned land. Remining has the multiple benefits of improving water quality, removing hazardous conditions, 2 and utilizing remaining coal as a resource instead of mining virgin land.

Prior to EPA's rule, 40 CFR Part 434 did not distinguish between pre existing discharges and new discharges from active mining areas. Requiring the treatment of pre existing discharges to meet existing standards was cost prohibitive, and, thus, a disincentive to remining activities. EPA established the Coal Remining Subcategory to address these regulatory disincentives and to encourage remining activities to reduce acid mine drainage and improve water quality.

The Coal Remining Subcategory only covers discharges resulting from previous mining activities on lands that have been abandoned ( termed a " pre existing discharge). A coal remining operator must determine baseline conditions by conducting monitoring and developing a sitespecific Pollution Abatement Plan designed to reduce the pollution load from pre existing discharges. The plan must incorporate the design and implementation of Best Management Practices ( BMPs). EPA published the Coal Remining Best Management Practices Guidance Manual ( EPA 821 B 01 010), which describes effective BMPs based on mine land conditions. Operators must ensure that the levels of iron, manganese, and net acidity in pre existing discharges do not worsen as a result of mining activities. They must follow a statistical procedure outlined by EPA to routinely monitor their pollutant loadings.

When the rule was promulgated, EPA projected the annual compliance cost for the Coal Remining Subcategory to be $ 0.33 to $ 0.76 million. The Agency projected total monetized annual benefits to be $ 0.70 to $ 1.2 million. EPA expects the regulation to significantly increase the rate at which abandoned mine lands are reclaimed, which will result in many non water quality benefits. These benefits, however, cannot be quantified.

Western Alkaline Coal Mining Subcategory Prior to the establishment of this Subcategory, all reclamation areas throughout the U. S., regardless of climate, topography, or type of mine drainage ( i. e., acid or alkaline), were required to meet the same discharge limits. EPA concluded, however, that there are unique environmental conditions in the arid west that are much different than those in other coal mining areas; thus, a need for this Subcategory was established.

In arid regions, the natural vegetative cover is sparse and rainfall is commonly received during localized, high intensity, short duration storms. These conditions contribute to flashfloods and turbulent flows that transport large amounts of sediment. Prior to establishment of this Subcategory, regulations basically required the construction of large sediment ponds to control sediment. The construction of these ponds to contain all runoff from areas that naturally contain large amounts of sediment can be difficult and can result in non water quality impacts that harm the environment, including disturbing the natural hydrologic balance, reducing groundwater recharge, reducing water availability, and impacting large areas of land for pond construction. The Subcategory was established to address these impacts. 3 The Western Alkaline Coal Mining Subcategory does not affect limitations for active mine wastewater. A coal mining operator must design and implement BMPs to maintain the average annual sediment yield equal to or below pre mined, undisturbed conditions. This ensures that natural conditions are maintained and does not allow a coal mining operator to increase the discharge of sediment over natural conditions. To achieve these results, the operator must conduct sediment yield monitoring, then develop a site specific Sediment Control Plan ( BMPs) using established watershed modeling techniques.

EPA estimated that the rule would result in a net cost savings to all affected surface mine operators and, at worst, would be cost neutral to affected underground operators. EPA projected that the Subcategory would result in annualized monetary benefits of $ 40,000 to $ 750,000.

2. NEED FOR AND USE OF THE COLLECTION 2( a) Need/ Authority for the Collection In January 2002, EPA amended wastewater regulations for the Coal Mining Point Source Category ( 40 CFR Part 434) by adding two new subcategories, the purpose of which was to address environmental issues not covered adequately by existing regulations. The addition of these subcategories is expected to ( 1) reduce severe and extensive damage resulting from abandoned mine lands in the Appalachian and mid continent coal regions and ( 2) reduce adverse environmental impacts resulting from the predominant use of sedimentation ponds for sediment control in the arid and semi arid western coal regions.

These regulations were promulgated under the authority of sections 301, 304, 306, 308, 402, 501, and 502 of the Clean Water Act ( CWA), 33 U. S. C. 1311, 1314, 1316, 1317, 1318, 1342, 1361, and 1362.

The CWA authorizes EPA to include Best Management Practices in effluent limitations guidelines and standards regulations. EPA's legal authority for regulations based on BMPs is found in section 402( a)( 1), section 402( a)( 2), and section 501( a) of the Clean Water Act, 33 U. S. C. 1251 et seq. EPA also relies on 40 CFR 122.44( d). The BMP regulation is consistent with the Pollution Prevention Act of 1990, 42 U. S. C. 13101 et seq., Public Law 101 508.

2( b) Practical Utility/ Users of the Data The primary users of the information generated under this ICR will be the coal mining companies that perform remining operations at abandoned mine lands and those companies that perform coal mining reclamation activities in the arid and semi arid coal regions of the western U. S. The data will also be used by NPDES control authorities in establishing baseline standards and in making compliance determinations. 4 3. NONDUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA 3( a) Nonduplication EPA's regulations for the two Subcategories build on, but do not duplicate, related regulations pertinent to the Coal Mining Point Source Category. These other regulations include those at 40 CFR Part 434, the Surface Mining Control and Reclamation Act, and the Rahall Amendment. Prior to the establishment of the two additional Subcategories, existing EPA regulations applied to four Subcategories only, including Coal Preparation Plants and Coal Preparation Plant Associated Areas; Acid or Ferruginous Mine Drainage; Alkaline Mine Drainage; and Post Mining Areas.

In 1977, Congress enacted the Surface Mining Control and Reclamation Act ( SMCRA), 30 U. S. C. 1201 et seq. To address the environmental problems associated with coal mining on a nationwide basis. The Act created the Office of Surface Mining Reclamation and Enforcement ( OSMRE) within the Department of Interior. Furthermore, it gave the office broad authority to regulate specific management practices before, during, and after mining operations. OSMRE has promulgated comprehensive regulations to control both surface coal mining and the surface effects of underground coal mining ( 30 CFR parts 700 et seq). Title IV of SMCRA addresses the problem of presently abandoned coal mines by authorizing and funding abandoned mine reclamation projects. EPA worked extensively with OSMRE in the preparation of the regulations for the Subcategories to ensure that the requirements were consistent with and not duplicative of OSMRE requirements.

As part of the 1987 amendments to the CWA, Congress added section 301( p), often called the Rahall Amendment, to provide incentives for remining abandoned mine lands that predate passage of SMCRA in 1977. The Rahall Amendment was intended to encourage remining by no longer requiring operators to treat degraded pre existing discharges to the Best Available Technology ( BAT) levels established in Subpart C of 40 CFR part 434. Despite the statutory authority provided, coal mining companies remained hesitant to pursue remining without formal EPA approval and guidelines. The Subcategories thus are EPA's response to industry's concern. The regulations are consistent with, but not identical to, the Rahall Amendment.

Coal Remining Subcategory As in the first ICR ( EPA ICR No. 1944.02 and OMB Control No. 2040 0239), EPA estimates that the baseline determination and annual monitoring required under the Coal Remining Subcategory impacts sites in 10 states. The monitoring requirements of the regulation are already required in whole or part by seven of the 10 states issuing Rahall permits for pre existing discharges at remining sites on abandoned mine lands. Three of the 10 states do not issue Rahall permits. EPA believes monitoring burden needs to be assessed for these states. Monitoring burden further needs to be assessed for some portion of the 10 states whose requirements are less 5 than those required under the Subcategory regulations. This incremental data collection and reporting burden for the baseline determination and annual monitoring is not provided elsewhere.

The SMCRA permit application process requires a coal mining operator to submit an extensive operation and reclamation plan, documentation, and analysis to OSMRE or the primacy permitting authority for approval. The requirements for the operation and reclamation plan are specified in 30 CFR part 780 for surface mining permit applications and part 784 for underground mining permit applications. Coal mining operators are required to provide a description of coal mining operations; a plan for reclaiming mined lands; a plan for revegetating mined lands; geologic information; hydrologic information including a description of baseline ground water and surface water characteristics under seasonal conditions; and an analysis of the hydrologic impacts caused by the mining activity. The plan must include a probable hydrologic consequences determination to determine the impacts of the mining on existing hydrologic conditions and a hydrologic reclamation plan to show measures for reducing impacts and to meet water quality laws and regulations. Furthermore, the coal mining regulatory authority is required to conduct a cumulative hydrologic impact analysis of the proposed operation and all anticipated mining on surface water and ground water systems.

EPA, therefore, believes that many requirements for the Pollution Abatement Plan will be contained in the operations and reclamation sections of an approved SMCRA permit. However, EPA or the state NPDES permitting authority retains the authority to require additional or expanded BMPs as necessary to ensure that implementation of the identified BMPs is consistent with CWA requirements.

Western Alkaline Coal Mining Subcategory For discharges at western alkaline coal mining sites, EPA incorporated BMP standards into the regulation by requiring that a site specific Sediment Control Plan be developed and implemented. The requirements of the plan are consistent with SMCRA requirements for mining operations as discussed above. Therefore, in most cases, the BMP requirements for the Sediment Control Plan will be satisfied by an approved SMCRA plan and will not result in duplication in reporting burden. However, EPA or the state NPDES permitting authority retain the authority to recommend additional or incremental BMPs, as necessary, to ensure that implementation of the identified BMPs is the best available technology economically achievable.

EPA has examined all other reporting requirements contained in the Clean Water Act and 40 CFR Parts 122, 123, 124, 125, 501, and 503. The Agency has also consulted other sources of information, such as the SMCRA and Rahall requirements discussed above, to determine if similar or duplicative information is available elsewhere. These examinations have revealed no additional duplicative reporting requirements. 6 3( b) Public Notice Required Prior to ICR Submission In compliance with the Paperwork Reduction Act ( 44 U. S. C. 3501 et seq), EPA solicited comments on the proposed information collection in the Federal Register prior to submitting this renewal ICR to the Office of Management and Budget ( 69 FR 52883, August 30, 2004). EPA received no comments.

3( c) Consultations EPA discussed development of the Subcategory regulations and the attendant record keeping and reporting requirements with the following organizations:

The Interstate Mining Compact Commission ( IMCC)

The National Mining Association ( NMA)

Western Interstate Energy Board ( WIEB)

The Office of Surface Mining Reclamation and Enforcement ( OSMRE)

Pennsylvania Department of Environmental Protection ( PADEP)

Other states

Tribes

Industry representatives

Other interested stakeholders 3( d) Effects of Less Frequent Data Collection The remining regulations require operators to collect data at a minimum frequency of once per month per pre existing discharge point for a 12 month period to enable a baseline standard to be established and at a frequency of once per month per pre existing discharge point thereafter to demonstrate compliance. The annual array of monthly monitoring data is necessary to determine an average discharge value and the variability associated with that value. Moreover, the frequency of collection allows for data representative of seasonal conditions. Without an adequate duration and frequency of sampling, the statistical procedures would often fail to detect genuine exceedance of baseline conditions or could establish baseline levels that are either too low or too high.

With regard to routine monitoring, EPA considers the frequency of data collection to be the smallest that would allow a significant probability of revealing a substantial increase above baseline levels within one year. If a facility fails to demonstrate compliance with the baseline standards, the monitoring frequency may be increased so that the permitting authority may monitor the pre existing discharge more closely and affect corrective action to re establish compliance. The duration, frequency, and seasonal distribution of sampling are important aspects of a sampling plan, and may effect the precision and accuracy of statistical estimates as much as the number of samples. To avoid systematic bias, sampling, during and after baseline determination, should systematically cover all periods of the year during which substantially high 7 or low discharge flows may be expected.

3( e) General Guidelines This information collection is consistent with OMB guidelines contained in 5 CFR 1320.5( d)( 2).

3( f) Confidentiality EPA does not expect that any confidential business information or trade secrets will be required from coal mining operators as part of this ICR. If information submitted in conjunction with this ICR were to contain confidential business information, the respondent may request that the information be treated as such. All data so designated will be handled by EPA pursuant to 40 CFR part 2. This information will be maintained according to procedures outlined in EPA's Security Manual Part III, Chapter 9, dated August 9, 1976. Pursuant to Section 308( b) of the CWA, effluent data may not be treated as confidential.

3( g) Sensitive Questions The reporting requirements addressed in this ICR do not include sensitive questions.

4. THE RESPONDENTS AND THE INFORMATION REQUESTED 4( a) Respondents and SIC Codes The respondents for this ICR will be approximately 234 coal remining sites on abandoned mine lands with pre existing discharges located in the Appalachian and mid continent coal regions and approximately 46 surface coal mining reclamation sites in the arid and semi arid western coal regions of the United States. These sites fall under Standard Industrial Classification or SIC codes 1221 ( Bituminous Coal and Lignite Surface Mining), 1222 ( Bituminous Coal Underground Mining), and 1231 ( Anthracite Mining). The corresponding North American Industrial Classification System or NAICS codes for these industries are 212111, 212112, and 212113, respectively. Government respondents are expected to be the 10 states that issue remining permits. These authorities will prepare new NPDES permits in the implementation of the regulation and will technically review a site's SMCRA reclamation plan to assess the adequacy of the BMPs incorporated. 8 4( b) Information Requested The regulations at 40 CFR 434.72 to 434.75 and 434.82 to 434.85 include the following major components:

Coal Remining Subcategory

Coal remining operators are required to perform and report baseline determinations for each pre existing discharge for net acidity, total suspended solids, iron ( total), and manganese ( total) at a frequency of once per month for 12 months. Thereafter, monitoring shall occur monthly. Monitoring may be increased if baseline standards are not met.

Coal remining operators are required to employ appropriate, site specific best management practices to result in the potential for improved water quality. This requirement is satisfied by implementation of a site specific Pollution Abatement Plan, subject to the review and approval of the NPDES permit authority.

Western Alkaline Coal Mining Subcategory

Western coal mining operators are required to apply appropriate, site specific best management practices that will result in average annual sediment yields that will not be greater than background levels from pre mined, undisturbed conditions. This requirement is satisfied by implementation of a site specific Sediment Control Plan developed using a watershed model and that describes best management practices. The Sediment Control Plan and model results are subject to the review and approval of the NPDES permit authority.

4( c) Respondent Activities Coal Remining Subcategory

Prepare basic information. Operators must collect baseline determination and monitoring data, develop the Pollution Abatement Plan ( which includes applicable BMPs) that will be described in the SMCRA Permit Reclamation Plan, and make reports to the NPDES permit authority.

Maintain records. All coal mining and remining operators must keep records of the monitoring information required by the regulation.

Western Alkaline Coal Mining Subcategory

Prepare basic information. Applicable operators must conduct modeling of sediment 9 yield, develop a Sediment Control Plan ( which includes applicable BMPs) that will be described in the SMCRA Permit Reclamation Plan, and make reports to the NPDES permit authority.

State NPDES Permitting Authorities

Prepare NPDES permits. State NPDES permitting authorities must review and approve baseline determinations, monitoring data and Pollution Abatement Plans or Sediment Control Plans, and incorporate baseline standards and BMP provisions into NPDES permits.

Conduct periodic reviews. State respondents are authorized to conduct periodic reviews of monitoring reports and SMCRA reclamation plans to assess compliance with baseline standards and BMP conditions contained in the site's NPDES permit.

5. THE INFORMATION COLLECTED: AGENCY ACTIVITIES, COLLECTION METHODOLOGY, AND INFORMATION MANAGEMENT 5( a) Agency Activities Upon approval of this ICR, permittees must maintain records as described above under Section 4( c). At least annually, they must submit a report to the NPDES authority summarizing the results of monitoring, the number and dates of any exceedances of baseline standards and corrective actions taken when standards have been exceeded. The NPDES permitting authority is authorized to review best management practices described in a site's SMCRA Permit Reclamation Plan, conduct compliance audits of facility records, review the data, and where necessary, conduct follow up activities. Follow up activities may include informal contact with the permittee ( by telephone or letter) to discuss the causes of any exceedances of baseline standards and the actions taken to correct the exceedences. The NPDES permit authority may also find it helpful to review monitoring records when developing future NPDES permit conditions.

5( b) Collection Methodology and Management Coal Remining Subcategory The data collection and management methodology for this Subcategory includes collection and reporting of baseline determination and monitoring data and reporting of the site specific Pollution Abatement Plan. This information is to be reported to the NPDES permit authority. Components of the site specific Pollution Abatement Plan are reported as part of the site's SMCRA permit application to the OSMRE permit authority. EPA believes that the BMP requirements for the Pollution Abatement Plan will generally be satisfied by an approved SMCRA plan and will therefore not duplicate reporting burden. However, EPA or the state NPDES 10 permitting authority retains the authority to recommend additional or incremental BMPs, as necessary, to ensure that implementation of the identified BMPs are the best available technology economically achievable.

Western Alkaline Coal Mining Subcategory EPA expects that the components required under the Sediment Control Plan will largely be satisfied by the SMCRA permit application to the OSMRE permit authority for this Subcategory. EPA assumes that the requirements for the Sediment Control Plan will largely be satisfied by materials generated as part of SMCRA permit application. However, the Sediment Control Plan and model results will remain subject to review and approval by the NPDES permit authority.

5( c) Small Entity Flexibility Pursuant to section 605( b) of the Regulatory Flexibility Act, the EPA Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities.

5( d) Collection Schedule The information collection activities included in this ICR are anticipated to occur according to the following schedule for each Subcategory:

Coal Remining Subcategory

Collect and report baseline determination data for pre existing discharges: Due at the time of permit application.

Submit Pollution Abatement Plan as part of a site's SMCRA permit application: Due at the time of permit application.

Collect and report subsequent monitoring data for pre existing discharges: Due with Monthly Discharge Monitoring Reports ( DMRs).

Western Alkaline Coal Mining Subcategory

Report sediment yield modeling results for a reclamation site: Due at the time of permit application.

Submit a Sediment Control Plan: Due at the time of permit application. 11 6. ESTIMATING THE BURDEN AND COST OF THE COLLECTION 6( a) Estimating Respondent Burden and Costs Tables 1 and 2 present estimates of the initial and recurring respondent burden ( respectively) for labor hours and costs associated with this ICR. The assumptions used in determining the respondent burden and costs are summarized below and footnoted in each table. The numbers presented in this ICR are based on assumptions consistent with those used in EPA's Economic and Environmental Impact Assessment but are presented in a different format. Dollar estimates in this ICR are not directly comparable because they differ in their use and presentation, including the use of midpoint values versus estimate ranges, the time period of analysis, and annualization of dollar values.

Table 3 presents estimates of the initial and recurring Agency burden and costs associated with this ICR. A summary of the respondent's burden hours and costs is presented in Table 4.

6( a)( 1) Estimate of the Number of Respondents Coal Remining Subcategory The potential number of coal remining respondents is documented in an EPA memorandum dated September 27, 1999 from John Tinger, EPA to Kristen Strellec, EPA, Subject: Final Estimation of Facilities Affected by Proposed Remining Subcategory. This memorandum estimates that approximately 78 permits per year may be issued. The duration of this ICR is three years and therefore the potential respondents over this time frame is ( 78 x 3) 234. EPA estimates the same number of respondents for this renewal ICR.

Western Alkaline Coal Mining Subcategory The potential number of respondents in this Subcategory is documented in the 1998 Keystone Coal Industry Manual. Using information from this reference, EPA estimates that there are approximately 46 potential respondents.

The Agency also compiled profile information on 24 existing underground coal mines in the arid and semi arid western states. Information provided by EPA's Office of Surface Mines indicates that underground mines will incur zero incremental modeling costs due to the small acreage and lack of complexity associated with these reclamation areas.

Although there are a total of 46 authorized NPDES states ( 45 states and 1 U. S. territory), the number of state NPDES authorities estimated to be impacted by the rule is 10. On September 3, 1998, the Interstate Mining Compact Commission ( IMCC) distributed a Solicitation Sheet to member states in support of continuing efforts to collect data and information required for proposal of a remining subcategory under 40 CFR 434. The solicitation sheet was intended to 12 gather information necessary to assess current industry remining activity and potential. IMCC member states estimated that there were 150 mining companies in 10 states actively involved in remining activities. Of these 10 states, seven issued Rahall type permits, while three did not ( see Table A). EPA believes the 1998 estimate by IMCC members is still representative of the industry.

6( a)( 2) Baseline Determination and Estimate of the Incremental Monitoring Burden and Cost The extent to which EPA will require additional monitoring for remining sites depends on the requirements the states incorporate in their Rahall remining permits. Table A below summarizes the number of samples or sites per year each state requires in their Rahall remining permits in terms of baseline determination and routine monitoring and then incremental monitoring for each of these categories. This table also shows the number of sites expected to be permitted under the regulations annually by state. 13 Table A.

EPA assumes for mine sites in Indiana and Tennessee that baseline determination monitoring and annual monitoring costs will be required for all of the reporting requirements. In addition, EPA assumes that flow metering from an installed weir will also be required for mine sites in these two states. For all other states, EPA assumes that flow metering will already be required and installed as part of the state Rahall remining permit program. Tables B and C below present the respondent burden and monitoring costs associated with incremental monitoring required by the Subcategory regulations for baseline determination monitoring and annual monitoring, respectively. Assumptions made for determining the respondent burden and costs are footnoted at the end of the tables. 14 Table B.

( b) Assumes 0.75 hours/ sample of labor burden based on PADEP estimates.

( c) Assumes a labor cost of $ 30.55/ hour. This estimate is up by $ 1.55 from the initial ICR. The initial ICR used an estimated labor cost provided by the PADEP. This ICR escalates that cost to 2004 dollars using the Consumer Price Index.

( d) Assumes a sample analysis cost of $ 23.17/ sample and mileage costs of $ 3.37/ sample for a total of $ 26.54/ sample ( up by $ 1.32/ sample from the previous ICR). The current ICR escalated the costs in the previous ICR to 2004 dollars using the Consumer Price Index, thereby resulting in these increases. Indiana sample analysis costs = 720 x $ 26.54 = $ 19,109 ( an increase of $ 965 from initial ICR). Kentucky sample analysis costs = 504 x $ 26.54 = $ 13,376 ( an increase of $ 675 from initial ICR). Tennessee sample analysis costs = 1,296 x $ 26.54 = $ 34,396 ( an increase of $ 1,737 from initial ICR). For Indiana and Tennessee assumes installed weir costs of $ 1,230 based on escalation of 2002 cost estimates from Weir & Flume Sales Company and Tarco Tech. Industries to 2004 dollars ( resulting in an increase of $ 62 from initial ICR). Indiana will have 5 sites/ yr x 3 years x 4 preexisting discharge points/ site x $ 1,230/ weir = $ 73,800 ( an increase of $ 3,720 from initial ICR). Tennessee will have 9 sites/ yr x 3 years x 4 pre existing discharge points/ site x $ 1,230/ weir = $ 132,840 ( an increase of $ 6,696 from initial ICR). 15 Table C.

( b) Assumes 25 hrs/ plan for review ( based on the SMCRA ICR burden for review of the reclamation plan) and 10 hrs/ site for NPDES permit preparation for a total of 35 hours/ site. For coal remining sites: 35 hrs/ permit x 234 potential permits = 8,190 hours. For western alkaline sites: 35 hrs/ permit x 46 potential reclamation sites in the arid and semi arid western states = 1,610 hours.

( c) The median salary for state and local white collar workers, excluding sales, is $ 25.15 or $ 52,312 per year based on 2,080 labor hours per year ( see Supplementary Table 3.1, State and local government, selected occupations: mean hourly earnings and percentiles, all workers, National Compensation Survey, July 2003, U. S. Bureau of Labor Statistics at http:// stats. bls. gov/ ncs/ ocs/ sp/ ncbl0636. pdf). This hourly rate is $ 5.35 higher than the rate included in the initial ICR, reflecting changes in compensation for state and local employees over time. Overhead costs for state and local employees are estimated to be 60 percent ( EPA ICR Handbook), or $ 15.09 per hour, which results in a total hourly rate of $ 40.24/ hour. 8,190 hours x $ 40.24 = $ 329,566, an increase of $ 70,107 from the initial ICR. 1,610 hours x $ 40.24 = $ 64,786, an increase of $ 13,781 from initial ICR. 17 Table 2.

The initial burden associated with preparation of a site's Pollution Abatement Plan or Sediment Control Plan is already covered by an applicable SMCRA ICR. The annual burden for coal mining and remining sites under the rule is estimated at 3,024 hours and $ 199,394 for annual monitoring at coal remining sites.

The initial burden for NPDES control authorities is estimated at 9,800 hours and $ 394,352 for review of SMCRA remining and reclamation plans ( which include BMPs) and preparation of the NPDES permit. The annual burden for NPDES control authorities is estimated at 2,340 hours 19 and $ 94,162 for review of annual monitoring data at coal remining sites.

The annual burden is 5,685 hours and $ 339,783.

6( d) Reasons for Changes in Burden The previous ICR had mistakenly used 3 year burden hours to calculate associated costs. This renewal ICR has corrected that error, resulting in decreased burden hours and costs.

6( e) Burden Statement For the Coal Remining Subcategory, the public reporting burden is estimated to average 21 hours per respondent per year. This estimate includes time for collecting and submitting baseline and annual monitoring results. For the Western Alkaline Coal Mining Subcategory, there is projected to be no additional public reporting burden. For the NPDES permitting authorities, the public reporting burden is estimated to average 405 hours per respondent per year.

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; 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.

To comment on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including the use of automated collection techniques, EPA has established a public docket for this ICR under Docket ID No. OW 2004 0026, which is available for public viewing at the Water Docket in the EPA Docket Center ( EPA/ DC), EPA West, Room B102, 1301 Constitution Ave., NW, Washington, DC.
