1. IDENTIFICATION OF THE INFORMATION COLLECTION 1(a) Title of the Information Collection This Information Collection Request (ICR) has EPA ICR number 1487.11(OMB control number 2050
- 0179) and is titled, “Consolidated Superfund Information Collection Request (Renewal).” This ICR combines three ICRs with the following information below:

- EPA ICR number 1488.08 (OMB contro l number 2050
- 0095) and title “Superfund Site Evaluation and Hazard Ranking Sy stem (Renewal) ”

- EPA ICR number 1487.11 (OMB control number 2050
- 0179) and title “Cooperative Agreements and Superfund State Contracts for Super fund Response Actions (Renewal) ”

- EPA ICR number 1463.0 9 (OMB contro l number 2050
- 0096) and title “National Oi l and Hazardous Substances Pollution Contingency Plan (NC P)(Renewal) ” 1(b) Short Characterization/Abstract

 **Superfund Site Evaluation and Hazard Ranking System** In 1980, Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to address threats posed to human health and the environment by uncontrolled releases of hazardous substances into the environment. Section 105 of CERCLA required EPA to establish criteria for determining priorities among releases or threatened releases of hazardous substances for the purpose of taking remedial action. In response, EPA developed a model to systematically rank hazardous waste sites with regard to their relative threat to human health and the environment. This model, the Hazard Ranking System (HRS), was adopted by EPA in 1982 and later revised in December 1990. The HRS criteria take into account the population at risk, the hazard po tential of the substances, as well as the potential for contamination of drinking water supplies, direct human contact, destruction of sensitive ecosystems, damage to natural resources affecting the human food chain, contamination of surface water used for recreation or potable water consumption, and contamination of ambient air. The Superfund site evaluation process uses a series of progressively more complex site assessment phases to determine and implement the appropriate responses to releases of hazardous substances to the environment. Exhibit 1 outlines the major components of the site assessment process.

At the conclusion of each phase of the site assessment process, the HRS model is applied to derive a preliminary site HRS score. The HRS score is crucial since it is the primary mechanism used to determine whether

a site is eligible to be included on the National Priorities List (NPL). The NPL is a list of those sites that are priorities for long
- term

evaluation and remedial response. Sites wi th HRS scores of 28.50 or greater are eligible for placement on the NPL. Only sites on the NPL are eligible for Superfund
- financed remedial actions. Sites with HRS scores below

28.5 generally require no further Superfund site evaluation. Uniform application of the HRS by the EPA, States and Tribes enables EPA to identify and prioritize hazardous waste sites that warrant further investigation. 1 Under this ICR, the States (including U.S. Territories) and Tribes will apply the HRS by collecting and documenting HRS data needs required for each site assessment phase conducted. EPA Regions work with States and Tribes to determine which sites will receive each type of assessment. The HRS data collected by States and Tribes during site assessment activities are derived from the sources described in this information collection, including conducting field reconnaissance, taking samples at the site, and reviewing available reports and documents. States and Tribes conclude each site assessment phase by completing and submitting the appropriate site assessment report to EPA. The number and type of assessment reports to be conducted by States and Tribes is a function of available funding, site assessment backlogs, Superfund site assessment goals, and site assessment priorities; therefore, the type of information collected under this ICR is considered to be a periodic report. The States and Tribes are reimbursed 100 percent of their costs to develop these reports, except for record maintenance. EPA Region s review each site assessment report submitted by States and Tribes for accuracy and completeness, and to ensure conformance with Superfund site assessment guidance. EPA Region s then use this information to make a decision regarding next Superfund steps fo r a site. EPA Region s also enter summary information about each report and the associated decision on next steps into the Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS). EPA maintains reports submitted by St ates and Tribes in site files. The annual burden incurred by States and Tribes for collecting information necessary to move a site through the site assessment process is a function of the average estimated hours and dollars per site assessment activity, the estimated number of assessment activities completed per year, and State/Tribal infrastructure costs supporting these assessment activities. In order to calculate the burden for this ICR, EPA Regions provided annual average estimates of site assessment activities to be completed by States and Tribes from FY 12 through FY1 4 . EPA Regions also provided estimated average hours and dollars incurred by States and Tribes to complete each type of site assessment activity, along with estimated infrastructure cos ts used by States and Tribes to perform Superfund work. Projected FY 12
- FY1 4 data provided by EPA regions show that the estimated annual hour and cost burden to State and Tribal respondents for performing site assessment activities is approximately 121,681 hours and $ 11,238,970 , respectively. However, o ne hundred percent of the respondent cost ( $ 11,238,970 ) is reimbursed by the EPA through cooperative agreements (CAs) as set forth by Section 104(d) of CERCLA , thus state and tribal respondents do not effectively bear any cost burden
. 2 Section 6.0 of this document, Estimating the Burden and Cost of Collection, provides a more detailed discussion of the burden to respondents. This ICR is prepared using the guidance contained in EPA’s ICR Handbook revi sed November, 2005. This document is the most recent document for preparing an ICR and follows the provisions of the Paperwork Reduction Act (44 U.S.C. §1320) and the Office of Management and Budget (OMB) guidelines.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  This ICR authorizes the collection of information under EPA’s Superfund Rule at 40 CFR Part 35, Subpart O, that establishes the administrative requirements for Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) funded cooperative agreements for State, political subdivisions, and Federally
- recognized Indian Tribes and Tribal Consortia response actions. The regulation includes only those provisions mandated by CERCLA, required by OMB circulars, or added by EPA to ensure sound and effective financial assistance management under this regulation. The information is c ollected from applicants and/or recipients of EPA assistance and is used to make awards, pay recipients, and collect information on how Federal funds are being utilized. EPA requires this information to meet its Federal stewardship responsibilities. Recip ient responses are required to obtain a benefit (Federal funds) under 40 CFR Part 31, “Uniform Administrative Requirements for Grants and Cooperative Agreements to State and Local Governments” and under 40 CFR Part 35, “State and Local Assistance.” It is estimated that the information collection will involve 284 new respondents and 389 amendments to existing agreements with recipients and impose a burden of 7,162 hours and $$220,221.59. Previous Information Collection burdens were approved under OMB contr ol number 2050
- 0179. The prior ICR was approved without any term s of clearance.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** This ICR a ddresses the portion of the NCP that details the requirements for remedial activities at sites on the National Priority List (Superfund Sites). The NCP is the rule that stipulates requirements for fulfilling the legislative mandates of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 as amended (CERCLA or Superfund). This ICR covers remedial activities conducted at state
- lead sites, participation by community members at all Superfund sites, Federally
- conducted community involvement activities, and Federal oversight of state activities. The information collected vi a these activities is critical to characterizing contamination at sites, determining appropriate remedies and goals for cleanup, and involving the community in the process. All of these steps help ensure that some of the nation’s worst hazardous waste sit es are cleaned up in a manner that is protective of human health and the environment, and, where practical, returned to productive use. 2. NEED FOR AND USE OF THE COLLECTION 2(a) Need/Authority for the Collection

 **Superfund Site Evaluation and Hazard Ranking System** CERCLA’s passage in 1980 launched the Superfund program that provided EPA the authority needed to respond to threats posed by the uncontrolled releases of hazardous substances into the environment. The fundamental purpose of the Superfund program is to address threats and protect human health and the environment from releases or potential releases of hazardous substances from abandoned or uncontrolled hazardous waste sites. The HRS is a crucial part of EPA’s Superfund program because its application enables EPA to evaluate the relative threats of hazardous waste sites. Collecting uniform information during the site assessment process enables EPA to consist ently apply the HRS model. Consistent application of HRS by respondents enables EPA to identify and classify those releases or threatened releases of hazardous substances that warrant further investigation in anticipation of corrective actions. EPA submitted the Agency's 20 11
- 201 5 Strategic Plan 3 to Congress on September 30 , 20 10 , as required under the Government Performance and Results Act (GPRA) of 1993. EPA’s strategic plan includes a target for

making a cumulative total of 93,400 Superfund site ass essment s by the end of FY 201 5 . The site assessment reports submitted by States and Tribes are included in this target
. CERCLA establishes the legal authority to perform site assessment and NPL li sting activities. Specifically Section 105 of CERCLA required that the National Oil and Hazardous Substance Pollution Contingency Plan (NCP) be amended to include the following: “[C]riteria for determining priorities among releases throughout the United States for the purpose of taking remedial a ction... Criteria and priorities... shall be based upon relative risk or danger to public health, welfare, or the environment... taking into account... the population at risk, the hazard potential of the hazardous substances... the potential for contamination of drinking water supplies, the potential for direct human contact, the potential for destruction of sensitive ecosystems... and other appropriate factors.” To meet these requirements, the HRS was adopted and enacted as part of the revised NCP in July 1982. Section 105(8)(B) of CERCLA requires the NCP to include a “list.... of national priorities among the known releases or threatened releases throughout the United States...” Application of the HRS determines whether an uncontrolled hazardous waste si te may be eligible for inclusion on the NPL. Each State is also required to “establish and submit for consideration by the President priorities for remedial action among known releases and potential releases in that State based upon the criteria” in Secti on 105(8)(A). In 1986, CERCLA was amended by the Superfund Amendments and Reauthorization Act (SARA). EPA mo dified the HRS in 1990 so that, “to the maximum extent feasible, [it] accurately assesses the relative degree of risk to human health and the environment posed by sites and facilities subject to review .” Section 105 of SARA mandates that the HRS take into account, to the extent possible, the following:

- Human health risks associated with the contamination or potential contamination of surface wate r that is or can be used for recreation or potable water consumption;

- Damage to natural resources that may affect the food chain; and

- Contamination or potential contamination of the ambient air, w hich is associated with the release or threatened release
. Section 118 of CERCLA requires that a high priority be given to facilities where the release of hazardous substances or pollutants has resulted in the closing of drinking water wells or a principal drinking water supply. Section 125 of CERCLA requires the HRS to assess sites containing a substantial volume of waste as described in Section 3001(b)(3)(A)(I) of the Solid Waste Disposal Act. These wastes include fly ash wastes, bottom ash wastes, slag wastes, and flue gas emission control wastes generated primarily from the combustion of coal or other fossil fuels. Section 125 of CERCLA requires EPA to consider each of the following site
- specific characteristics:

- Degree of risk to human health and the environment;

- Quantity, toxicity, and concentration s of hazardous constituents; and

- Extent of and the potential for the release of hazardous constituents into the environment. The specific sections of CER CLA cited above can be found at http://frwebgate.access.gpo.gov/cgi

.
 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  This ICR is necessary due to the information collection and reporting requirements in the Superfund rule 40

### 8

CFR Part 35, Subpart O, “Cooperative Agreements and Superfund State Contracts for Superfund Response Actions.” Due to the statutory cost recovery requirements in CERCLA and the need to carefully track all costs, Superfund recipients must comply with administrative requirements sufficient to meet these provisions of the la w. The regulation sets forth the pre
- aw ard, post
- aw ard, and closeout cooperative agreement requirements which are conditions for receiving/managing a Superfund Cooperative Agreement (CA) or a Superfund State Contract (SSC). This information is needed by EPA project officers, grant specialists, and finance officials to manage/oversee the funding activities and cleanup activities at Superfund sites. EPA also uses the information to update the Com prehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) which tracks progress made at Superfund sites, and to update IFMS, EPA’s database for tracking financial management.

 **National Oil and Hazardous Substances Pol lution Contingency Plan (NCP)**  CERCLA authorizes the President to undertake removal and remedial actions in response to releases, or threats of releases, of hazardous substances and certain pollutants and contaminants into the environment. Revisions were m ade to the NCP in 1982 to incorporate the provisions of CERCLA. These revisions to the NCP established procedures for data collection, analysis, and reporting to be conducted during remedial and removal responses at Superfund sites. Subsequent revisions t o the NCP in 1985 added additional procedures. Finally, the Superfund Amendments and Reauthorization Act of 1986 (SARA) amended CERCLA and mandated, among other provisions, that the NCP be revised within 18 months of the date of enactment of SARA to incor porate provisions of the new law (42 USC 9605(b)). The revised NCP, published in March 1990, included new reporting and record keeping provisions for Superfund remedial responses as described in 40 CFR 300.430 and 300.435. EPA uses the information provided by the states to ensure state actions are consistent with the provisions of CERCLA and SARA and that their decisions are protective of human health and the environment. EPA uses the information gathered from private citizens to plan activities geared to educating them where necessary, keeping them informed of activities within the community, and ensuring they have had an opportunity to assume an active role in the decision making process that affects their community. EPA also uses information from private citizens to measure the effectiveness of community involvement activities and to improve those activities as needed. EPA believes involvement of the members of the community surrounding a Superfund site is critical to ensuring effective site cleanups. 2(b) Practical Utility/Users o f the Data

 **Superfund Site Evaluation and Hazard Ranking System** The data collected through the site assessment process described in this ICR are used to support a site decision regarding the need for further Superfund action. The various data elements gathered, w hich relate to the HRS criteria, are used to complete the HRS score. All of this information is used within the Superfund program to:

- Identify sites that pose a potential threat to human health and the environment;

- Determine if sites pose a potential hazard and whether further action is necessary;

- Re fer sites to EPA’s removal program if removal actions may be needed ;

- Develop preliminary and final HRS scores ;

- Set priorities for further assessment work;

- Allocate resources (e.g., money, staff); and

- Evaluate Superfund program performance. In addition, EPA Headquarters’ staff use the information collected to aid in the general management and oversight of the Superfund program. Currently, EPA uses the information to assess resource needs; allocate funds; prepare site assessment guidance materials; list NPL sites; conduct quality assurance (QA) reviews of HRS packages; and track Regional and State Supe rfund performance. Headquarters also uses the information to respond to information requests, and perform analyses for EPA management, OMB, Congress, and the general public.

### 9 Staff at the ten EPA Regions use Superfund site assessment data for purposes similar to Headquarters , including: d evelop ing operating budgets and program plans; allocating resources; tracking State
- by
- State performance; respond ing to information inquiries under the Freedom of Information Act (FOIA); and supply ing input to CERCLIS. EP A regions also use the data to help identify which cleanup option should be used to address sites needing potential remediation (e.g., NPL listing, RCRA, state cleanup program). Regions must also respond to inquiries from EPA

Headquarters. As a function o f their program authority, EPA Regions also have the responsibility for overseeing site assessments and generating HRS scores. State and Tribal use of site assessment data is more site
- specific. These authorities use the data to perform site assessments; generate HRS scores; maintain site files; track site status; and respond to informati on inquiries under FOIA. They also use the information gathered to maintain their own site files. Exhibit 2 summarizes the use and users of site assessment and HRS information.

 **Cooperative Agreem ents and Superfund**  **State Contracts for Superfund Response Actions** The information collected is used by EPA to manage and administer cooperative agreements and Superfund State Contracts for Superfund response actions. The pre
- aw ard information is used to qualify cooperative agreement applicants and award cooperative agreements. The post
- aw ard information is used to meet the statutory and

### 10

regulatory requirements and monitor recipient performance. The closeout information is used to meet reporting and record keeping requireme nts necessary for cost recovery purposes and for closing out awards. The information is necessary to ensure fiscal control and accountability for Superfund money to deter waste, fraud, and abuse. 40 CFR Part 35, Subpart O, also supplements EPA’s general assistance regulation, 40 CFR Part 31, “Uniform Administrative Requirements for Grants and Cooperative Agreements to State and Local Governments.” Part 31, which implements the requirements of OMB Circular A
- 102, became effective for awards made on or aft er October 1, 1988. The Part 31 rule (common rule) established uniformity among Federal agencies that award Federal grants and cooperative agreements to States, political subdivisions thereof, and Federally
- recognized Indian Tribes and Tribal Consortia. Many of the information collection requirements for Superfund cooperative agreements were approved under the OMB Paperwork Clearance #2030
- 0020 associated with 40 CFR Part 31 prior to this ICR. Due to statutory cost recovery requirements, and the need to carefully track costs by site and activity, Superfund recipients must comply with all administrative requirements to satisfy the provisions of the law. There are additional requirements in this regulation, which supplements Part 31, and are necessary for effective cost recovery from potentially responsible parties. States may be able to follow their own rules for certain aspects of the program, such as in procurement, if their administrative requirements and financial management capabilities are sufficie nt.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** The lead agency, whether EPA or the state, conducts many data
- gathering activities, including development of the Remedial Investigation/Feasibility Study (RI/FS) and the preparation of the Proposed Plan and the Record of Decision (ROD). This data is used by the lead agency to make informed decisions regarding remedial responses. When states assume the lead agency responsibilities, EPA Regions use the information collected to oversee states in the conduct of remedial responses at hazardous waste sites. Spe cifically, this information is used to ensure that remedies are selected in accordance with CERCLA and the NCP, that cleanup standards are attained, and that community concerns are appropriately addressed. The data are also made available to the public and may help community members understand health risks and participate in site
- related decisions. States also identify all potential applicable, relevant, and appropriate requirements (ARARs) at all state
and Federal
- lead sites during the RI/FS. The ARA Rs are used to determine cleanup levels and to select the remedy to be used at a site. ARARs include chemical
- specific, location
- specific, and action
- specific levels that may need to be met at a site for it be determined protective of human health and the environment. These levels may be contained in federal statues, such as the Safe Drinking Water Act or the Endangered Species Act, or in state la ws, which must be used if the levels are more stringent than those promulgated in a corresponding federal stat ute. Community interviews and information provided by community groups are used by the lead agency to ensure public involvement in site
- related decisions, as required by CERCLA and SARA, and provide appropriate opportunities for the community to learn abo ut the site. EPA uses the information gathered through research instruments, such as satisfaction surveys, to obtain timely feedback on the community involvement process at the site level. Communities are viewed as integral participants in the Superfund cleanup process and their early and often involvement can often expedite cleanup and result in future reuse that meets the communities’ needs. 3. NON
- DUPLICATION, CONSULT AT IONS, AND OTHER COLLECTION CRITERIA 3(a) Non - duplication

 **Superfund Site Evaluation and Hazard Ranking System**

### 11 The primary sources of data required to complete site assessments and prepare HRS packages are Federal, State, and local government agencies and private parties. Data are gathered through the various electronic data sources and through the performance of actual on
- site investigations (e.g., samples, on
- site measurements). Much of the information (i.e., site history, population surrounding the site, location of drinking water supplies) is collected from readily available public information sources, thereby minimizing the amount of collection of this primary information. The field data gathered during the site assessme nt activities covered under this ICR are not generally collected by any other Federal agency from these state and tribal respondents
. Through pre
- CERCLIS screening s and Abbreviated Preliminary Assessments , EPA screens out sites being addressed by other parties to prevent duplication of assessment activities. Generally, the SI is the first investigation to collect and analyze waste and environmental samples. In instances where prior sampling has been comp leted and analytical data has been collected, performance of additional sampling may not be necessary.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  All information collected is used to continue administering cooperative agreements and Superfund State Contracts for Superfund response actions. This data is not available from other sources, as it is specifically related to the requirements of 40 CFR Part 35, Subpart O, and the award, management, and closeout of cooperat ive agreements and Superfund State Contracts within this program.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** Duplication of other Federal data collection efforts is expected to be minimal. Site information is gathered cumulat ively from identification through remedial action. To the extent practicable, respondents are encouraged to use information in the site file to inform other subsequent activities at the site. 3(b) Public Notice Required Prior to Submission to OMB A notice stating this ICR was up for renewal was published in the Federal Register on August 10, 2012 (7 7 FR 47835 ) . This initiated a 60
- day comment period . No comments were received during the comment period. 3(c) Consultations

 **Superfund Site Evaluation and Hazard Ranking System** In order to calculate the burden of site assessment activities on the States and Tribes and present the results in this report, State and Tribal burden information was based on average annual site assessment activity projection s for FY 20 12 through FY 201 4
. As part of obtaining the State and Tribal burden information, EPA Region s were contacted to determine the nature of site assessment activities p erformed by States and Tribes in each respective Region and the costs (dollars and hours) associated with these activities. EPA Region s reviewed cooperative agreement progress reports submitted by States and Tribes as necessary to gather the State and Tribal data for this ICR.

 **Coope rative Agreem**  **ents and Superfund State Contracts for Superfund Response Actions** This is a request for renewal of an information collection request, and in addition to the initial Federal Register notice, the following organizations were contacted to provide additional input towards the calculation of burden imposed by this ICR: Bureau of Waste Site Cleanup Massachusetts Department of Environmental Protection One Winter St. Boston, MA 02108

### 13  **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** An EPA Superfund database that is updated daily provides the basis for the actual (for the time period FY 2008
- 2010) and planned number of proposed plans, RODs and active NPL sites in this ICR. These numbers, in conjunction with best professional judgment, serve as the foundation from which estimates of the num ber of activities (e.g., RI/FS, Community Involvement Plans, etc.) were developed in consultation with subject matter experts in both EPA Headquarters and Regional offices. Discussions with these experts involved feedback on the accuracy of burden and cost estimates. Agency experience in addressing community issues has included semi
annual or annual meetings with Regional community involvement staff, meetings with groups of states, and meetings with citizen groups. Finally, information from actual histori cal contract activity inform the estimates of the number of hours to perform an RI/FS as well as the breakout of labor type when developing an RI/FS. 3(d) Effects of Less Frequent Collection

 **Superfund Site Evaluation and Hazard Ranking System**  Site assessment information collection does not occur on a regularly scheduled basis. Yearly collection activities associated with the site assessment process are based on the number of sites discovered , the numbe r of sites in the CERCLIS inventory needing assessment work , the amount of available Superfund funding, and Superfund site assessment goals and priorities
. The frequency of collection is driven by the schedule established in Section 116(b) of CERCLA. Sec tion 116(b) requires an HRS evaluation (if warranted) within four years of the site's entry into CERCLIS. 4 For sites brought to EPA’s attention via a citizen’s petition, Section 105(d) of CERCLA requires completion of a P reliminary Assessment (P A) , or an explanation of why a PA is not appropriate, within one year after receiving the petition. Less frequent collection of site assessment reports may compromise EPA’s ability to comply with statutory schedules and could negatively impact EPA’s progress toward s achieving the strategic target for com

pleting Superfund site assessments
.
 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  There is no fixed schedule for the collection of this information. It is required on an as needed basis as stated in the rule at 40 CFR Part 35, Subpart O, “Cooperative Agreements and Superfund State Contracts for Superfund Response Actions.” Therefore, there is no possibility that the information can be collected less frequently than required by the regulation.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** Information is collected as appropriate to the remedial stage of the Sup erfund process. The frequency of these collections vary depending on several factors at the site, such as complexity of issues, cleanup technology used, level of community interest, and duration of cleanup. Information collection frequencies outlined in the NCP are the minimal amount necessary to ensure cleanup of NPL sites and the proper implementation of CERCLA. 3(e) General Guidelines The reporting frequency guideline set forth in 5 CFR 1320.6 of the Paperwork Reducti on Act Guidelines may not be met depending on the nature of new sites discovered and urgency of assessment work needed. Collection of information occurs continually as ne w sites are identified. EPA is currently operating NPL development activities so that as sites with higher priorities are identified, the information is forwarded to the appropriate office for review and validation.

bin/usc.cgi?ACTION=BROWSE&TITLE=42USCC103

.

### 14 States and Tribes have at least 30 days in which to respond to any information requests specified in the NCP. This time fr ame is in compliance with the Paperwork Reduction Act guidelines. The record retention period for administrative records is not specified in the National Contingency Plan. The site records are to be maintained for the duration of the assessment and any s ubsequent remediation at sites and for as long as necessary for litigation purposes. Responsibility for these files will continue beyond the three year ICR period, as assessment and, if necessary, remediation may take more than three years. 3(f) Confidentiality

 **Superfund Site Evaluation and Hazard Ranking System** Application of the HRS does not typically require collection of information that is considered confidential. EPA handles instances where confidentiality claims are asserted by private parties on a case
- by
- case basis. States and Tribes (the respondents) have been informed that any confidential information submitted to document an HRS score must be marked clearly as such and sent under separate cover so that it is properly handled.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  None of the information being collected will contain sensitive questions or require collecting sensitive information.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)**  The nature of the data being gathered as part of this information collection is not confidential. Information may be gathered from Potentially Responsible Parties (PRPs) that the PRP considers to be Confidential Bu siness Information (CBI). When information is designated as CBI by a PRP, EPA follows restricted access procedures in handling the information. These procedures include keeping the information in locked areas and only allowing CBI
cleared personnel ac cess to the information. PRP information is gathered in anticipation of litigation. EPA, therefore, does not have to grant Freedom of Information Act requests for this information. Lists of participants in community interviews and lists of attendees of public meetings are not confidential. Some data gathered during community intervie ws may not be releasable, however, due to privacy concerns. 3(g) Sensitive Questions None of the information being collected will contain sensitive questions or require collecting sensitive information
. 5 4. THE RESPONDENTS AND THE INFORMATION REQUESTED 4(a) Respondents Standard Industrial Classification (SIC) Codes

 **Superfund Site Evaluation and Hazard Ranking System** Activities conducted as part of the Superfund site assessment process require that information be gathered from Federal, State, and local government agencies. While the performance of the various phases of site assessment will require the involvement of S tate and local agencies, identification of the particular State or local agency
5 As stated in EPA’s IC R Handbook , revised November 2005, sensitive questions are those concerning sexual behavior, attitudes, religious beliefs, or matters usually considered private.

involved is not possible until a site has been identified. SIC codes associated with e nvironmental p rotection a gencies (governmental) are classified in Division J, Public Admi nistration; Major Group 95, Administration of Environmental Quality and Housing Programs; Industry Group 951, Administration of Environmental Quality; and 9511 Air and Water Resource and Solid Waste Management. The corresponding North American Industry Cl assification System (NAICS) code is 924110: Administration of Air and Water Resource and Solid Waste Management Programs.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  The respondents to the recordkeeping and reporting requirements are Other General Government Support (SIC Code 9119, NAICS Code 921190), American Indian and Alaska Native Tribal Government (SIC Code 8641, NAICS Code 921150).

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** Responde nts to this ICR are state/tribal governments and individual community members who voluntarily participate in the remedial phase of the Superfund program and in associated community involvement activities throughout the Superfund process. SIC Codes are OSH A’s Standard Industrial Classification System used to identify different groups. State/tribal governments are categorized as Division J: Public Administration, Major Group 95: Administration of Environmental Quality and Housing Programs, Industry Group 95 1: Administration of Environmental Quality, subgroup 9511: Air and Water Resource and Solid Waste Management. The other respondents, community members, do not have a SIC Code as they do not constitute an industry. 4(b) Information Requested

 **Superfund Site Evaluation and Hazard Ranking System** The data collection requirements associated with the various phases of the site assessment process are d esigned to enable the consistent application of the HRS. Information gathering activities are intended to help EPA determine whether hazardous substances are present at the site, and whether they are migrating to the surrounding environment. Data required for the site assessment process and HRS score preparation are often collected from readily available public information sources such as State and local government offices, Regional EPA offices, and potentially responsible parties (PRPs). The amount of data collected during the site assessment process and the activities as sociated with collection vary from site to site depending on the level of proposed threat. Data collection activities also vary from phase to phase of the site assessment process based on the type of information needed to satisfy the HRS requirements such as waste characterization and target assessments
. Although reporting activities (e.g., data collection, report preparation) comprise the majority of the site assessment effort, approximately 13 percent of the total effort can be attributed to recordkeeping activities (e.g., developing and maintaining databases, entering data, and filing). This section provides a detailed description of the type of data that needs to be collected to complete a site assessment and the activities associated with this collec tion process. It also provides estimates of the average annual projections of number of respondent activities from FY 20 12 through FY 201 4
. State and Tribal respondents submit a site assessment report to EPA for each activity conducted. EPA enters ke y information contained in these reports into CERCLIS. Collection activities are discussed for the major phases of site assessment including: Pre
- CERCLIS Screening, Preliminary Assessment, Site Inspection, and HRS Package Preparation. Other assessment activities are also described, including: Integrated Removal/Remedial Evaluation (Integrated Assessment), Expanded Site Inspection and Site Reassessment
.

### 16 Exhibit 3 provides an overview of the activities performed and data items collected for the various phases of site assessment . It also illustrates where the sub
-phases may be utilized and the various outcomes that can occur
. Section 6.0, Estimating the Burden and Cost of Collection, provides the estimated average hours associated with each of the phase s of the site assessment process.

Pre - CERCLIS Screening Pre - CERCLIS screening is the process of reviewing data on a potential hazardous waste site brought to EPA’s attention to determine whether it should be entered into CERCLIS for further evaluation or response action
. 6 Pre - CERCLIS screening is intended to be a low
- cost effort to ensure uncontaminated or lightly contaminated sites are not arbitrarily entered into CERCLIS for Superfund
- financed evaluation, cleanup, or oversight activities. The

process can be initiated through the use of several mechanisms, such as a phone call or referral by a State or other Federal agency. Following notification of a potential site to EPA, Regions generally contact State, Tribal, or other appropriate Federal staff to determine whether the site is already being addressed by another party and to define EPA’s role at the site. From FY 20 12 through FY 201 4 , EPA projects an annual average of 268 Pre - CERCLIS screenings will be performed by State s or Tribes. Preliminary Assessment The preli mi nary assessment ( PA) is a relatively rapid, low
- cost compilation of readily available information pertaining to the site and its surroundings
. 7 From FY 20 12 through FY 201 4 , EPA projects an annual average of 140 PAs will be performed by States or Tribes to identify target populations and other targets that may be affected by contamination at sites . The scope of the PA must be sufficient to complete several activities , including :
 Revie wing existing information about the site;  Conducting a site and environmental reconnaissance;  Collecting information about the site, with the emphasis on target information;  Evaluating all information and developing a preliminary HRS score; and  Preparing a brief site summary report and site characteristics form. Data collected during PA activities include: site
- specific data, historical site information, potential contamination sources, types of hazardous waste, target information, and location of drinking water supplies
. Samp ling activities are not performed during this phase of site assessment. In certain situations, an Abbreviated PA (APA) 8 may be conducted in lieu of a full PA. APAs are appropriate when the following conditions exist:

 A site has been inappropriately l isted in CERCLIS because it is either not eligible or it could be deferred to another response program;  A site can be addressed as part of another site already in CERCLIS;  Available information allows EPA to make an early decision to undertake a Site Inspection (SI) ; or  A NFRAP designation can be made without completing a full PA. For such sites, the typical PA reporting requirements are abbreviated. Site Inspection SIs build upon and supplement the information collected during the PA. The primary p urpose of the SI is to gather enough information to determine whether further Superfund action is warranted as a result of a significant threat to human health and the environment
. 9 From FY 20 12 through FY 201 4 , EPA projects an annual average of 58 SIs wi ll be performed by States or Tribes. During the SI, the respondent will collect data to determine whether the site is an NPL candidate or if it should receive a NFRAP or other decision (i.e., deferral to RCRA, further assessment needed). The SI consists of five major activities:

### 18  Revie wing available information including analytical data;  Organizing the project team and developing an SI work plan, sample plan, health and safety plan, and investigation
- derived wastes (IDW) plan;  Performing field work to visually inspect the site and collect samples;  Evaluating all information and developing a site score based on the HRS; and  Preparing a site summary report. Data collected during the SI could include additional non
- sampling data (e.g., field observations, site
specific information) and sampling data collected during the on
- site reconnaissance. Integrated Removal/Remedial Evaluations (Integrated Assessments) Site assessment and removal assessment activities may be combined into a single Integrated Assessment activity if the appropriate site conditions exist. 10 Integrated Assessments further reduce repetitive tasks and costs on site characterization. The two mo st common types of Integrated Assessments include : Integrated Removal Assessment & PA; and I ntegrated Removal Assessment & SI . From FY 20 12 through FY 201 4 , EPA projects an annual average of 2 Integrated Assessments will be performed by States or Tribes. The stand
- alone requirements from the site assessment and removal assessment a ctivities must be met even though the data will be integrated. 11 Expanded Site Inspection The ESI further investigates critical hypotheses proposed in the SI regarding the nature and extent of contamination at a site. ESIs typically include additional sit e sampling, which in some cases, may require specialized techniques or equipment (e.g., installation of monitoring wells, geophysical surveys). Data generated are used to modify the preliminary HRS score developed during the SI. An ESI report is the fina l product of this phase. ESI activities should include:

 Organizing the project team and developing ESI work plan, sample plan, health and safety plan, and IDW plan;  Investigating and documenting critical ne w hypotheses or assumptions;  Collecting samples to attribute hazardous substances to site operations;  Collecting samples to establish representative background levels;  Collecting other missing non
- sampling data for pathways of concern; and  Preparing a site summary report. The data collected during the ESI may be used to support previous documentation or references, and fulfill remaining HRS data requirements for pathways of concern. 12 From FY 20 12 through FY 201 4 , EPA projects an annual average of 22 ESIs will be performed by States or Tribe s. Site Reassessment The Site Reassessment represents the gathering and evaluation of new information on a site previously assessed under the Federal Superfund program to determine whether further Superfund attention is needed. The scope of work for a Site Reassessment activity is flexible, but will usually represe nt a component of PA or SI activities. As such, it serves as a supplement to previous assessment wo rk, and not as a substitute for an initial PA or SI

HRS Package Preparation The final phase in the site assessment process is HRS package preparation. The primary activities associated with this phase of site assessment are:

 File review;  Determining site score;  Revising site score; and  Preparing the documentation record and supporting information. After completion of the site evaluation, compiled data are used to score a site using scoresheets based on the HRS model. Under the HRS, numerical values are assigned to a site based on various aspects of the site and its immediate surroundings through th e evaluation of four pathways: (1) ground water migration; (2) surface water migration; (3) soil exposure; and (4) air migration. The scoring system for each pathway is based on a number of individual factors grouped into three factor categories: (1) likelihood of release or, for the soil exposure pathway, likelihood of exposure; (2) waste characteristics; and (3) targets (i.e., potentially affected populations, etc.). Individual factors are evaluated and the factor values are calculated to produce four category values. An example of the scoresheets used during HRS package preparation can be found at http://www.epa.gov/superfund/training/hrstrain/htmain/index.htm
. From FY 20 12 through FY 201 4 , EPA projects an annual average of 9 HRS packages will be p erformed by States or Tribes.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  **(i) Data Item s (Including recordkeeping requirements)**  Information requested

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** This ICR requests information from states at state - lead sites as it relates to CERCLA activities. Each of the following categories will be addressed in detail in this section: RI/FS, Proposed Plans, RODs, ARARs, Administrative Record, initial and revised Community Involvement Plans (CIP), Fact Sh eets, focus groups, and workshops. Information is also requested on a voluntary basis from community members at all active Federal and state lead sites. The following community activities will be addressed in detail in this section: initial and revised C IP interviews, focus group participation, workgroup participation, TAG application, TAG management, and satisfaction surveys. Federal activities will be discussed in a subsequent section of this document. **(i) Data item s, including record**  **- keeping require**  **me nts**  Remedial Investigation/Feasibility Study The first step in conducting the RI/FS, which is authorized under CERCLA §104 (42 USC 9604(a)(1); 40 CFR 300.430), is the development of a project plan, which describes the scope and content of the RI/FS and in cludes work plans. Work plans are developed as part of the project plan and detail the site management strategy. The work plans identify initial boundaries of the study area, likely remedial response objectives, operable units (if any), and the procedure s that will be followed to satisfy the strategy. In addition, an initial site evaluation is presented in the typical work plan. This evaluation includes:

- Site description;

- Preliminary definition of the contamination problems;

- Likely contaminant migration pathways;

- Environmental and health effects associated with migration; and

- Description of any initial remedial measures for the site. A preliminary assessment of remedial alternatives may be included in the work plan. The data requirements necessary to support the selection of a remedy are also discussed. Based on preliminary site information, the objectives and the scope of work for the RI and FS are developed. The scope of work for the RI includes many components, including plans for project operations that will be followed in conducting a survey of the study area, in characterizing the source of contamination, and in identifying F ederal and state ARARs. The work plan also includes procedures that will be followed in evaluating contamination pathway and transport, and in evaluating the potential risk to public health posed by the site. Plans for testing the feasibility of remedial technologies may also be included. Initial data quality objectives, quality

### 21

assurance procedures that will be followed, procedures to be followed in preparing the RI report, and information on the technical and financial management of the RI project also are discussed in the RI scope of work section of a site work plan. The sampling and analysis plan for a site is developed during the scoping phase of the RI. This plan describes the sampling, calibration, and analytical procedures that will be followed in collecting air, water, soil and source samples. Additionally, quality assurance objectives to be met throughout the sampling task are discussed. These objectives include procedures that will be followed to ensure the accuracy and precision of the anal ysis, as well as the completeness, representativeness, and comparability of the sampling. Hundreds of samples are taken during the typical RI, and the analysis of the site samples provides basic information on the concentration, source, and potential path s of migration of contaminants at a site. Sampling and analysis plans generally include a project description that summarizes the site history, environmental setting, and project objectives such as the media to be sampled, sampling locations on the site, and sampling schedule. A health and safety plan is drafted that identifies potentially hazardous operations and exposures, and prescribes appropriate protective measures. In the scope of work for the FS, procedures are established for developing remedia l alternatives for the site. Alternative screening and analysis procedures, methods for conducting a comparative evaluation of acceptable alternatives, and details on preparing the FS report are included. Concurrent with the preparation of the RI work p lan, EPA conducts community interviews, as required by the NCP, in preparation for the required Community Involvement Plan, which must be finalized before any RI field work begins. Upon completion and approval of the work plans and sampling and analysis plans, the RI/FS can begin. The RI/FS includes site work, analysis of data, and preparation of the RI report. Drilling and sampling detailed in the sample and analysis plan requires not only time spent at the site boring holes in the earth and taking air and water samples, but also time to mobilize drilling equipment and to train personnel in the sampling and decontamination techniques to be used at the site. Upon completion of the site work, the samples are sent to a laboratory for evaluation, and the r esults of the analyses are verified. Standard evaluation techniques include analyzing samples for organics, metals, and cyanide. The RI serves as the mechanism for collecting data for site and waste characterization and for conducting treatability testing as necessary to: (1) evaluate the performance and cost of the treatment technologies considered for use at a site; and (2) support the design of selected potential remedies. The FS serves as the mechanism for the development, screening, and detailed evaluation of potential remedial alternatives. The RI and FS are conducted concurrently. Data collected in the RI influence the deve lopment of remedial alternatives in the FS, which in turn affects the data needs and scope of treatability studies and additional field investigations. The site characterization developed during the RI provides the data necessary to estimate the risks to human health and the environment posed by a site, to establish cleanup goals or ranges, and to identify viable cleanup alternatives. The FS draws upon the data collected and analyzed during the RI in the process of developing alternatives and conducting a detailed analysis of the most viable alternatives. Because of the interactive nature of this process, the sequence of the various phases and associated activities frequently will not be distinct in practice. A risk assessment is conducted during the RI to estimate the health consequences of exposure to contaminants at a site. In this assessment, the physical and chemical properties of hazardous substances and their toxicological effects are studied to determine the potential for the substances to cause adverse health effects, and the likely pathways and magnitude of exposure of populations and/or individuals near the site. An evaluation of dose
response information is completed to estimate the health effects (e.g., incident of certain diseases) that may result from exposure to the hazardous or toxic substances at a site.

### 22 A risk characterization brings together the exposure and the dose
- response information to predict the likely range and severity of health effects that may occur as a result of the sub stances at a site, and the number of people affected. The uncertainty evaluation is an integral part of the risk assessment process; it identifies the degree of uncertainty associated with the final risk estimates by identifying uncertainties related to the data and the assumptions. This uncertainties evaluation places bounds on the final estimate and target areas needing im provement. The FS process includes the initial evaluation and screening of a number of potential alternatives. Alternatives are eliminated from further evaluation for a number of reasons, including technical problems, lack of effectiveness in the long term or short term, failure to protect human health and the environment, cost, or im plementation time. The universe of potential remedi es is reduced to a reasonable number (usually between three and five) of good alternatives on which detailed analyses are conducted. If existing site and treatment data are insufficient to evaluate the alternatives adequately, treatability tests may be ne cessary to evaluate a particular technology or specific site wastes. Treatability tests generally involve bench
- scale testing to assess the feasibility of a technology, although a pilot
- scale study may be required in a few situations. Once sufficient data are available, alternatives are evaluated in detail with respect to nine evaluation criteria: protection of human health and the environment; compliance with ARARs; long
- term effectiveness and permanence; reduction of toxicity, mobility, or volume; short - term effectiveness; im

plementability; cost; support agency acceptance; and community acceptance. The alternatives are evaluated individually against each criterion and then relative to other alternatives to understand the strengths and weaknesses of ea ch alternative. At the end of this analysis process, the RI/FS report is prepared. For the purposes of this analysis, EPA estimates that there will be an average of 95 RI/FS per year. This estimate includes new and on
- going RI/FS. The state
- lead porti on of these RI/FS is estimated to be 19 RI/FS per year over the three
- year ICR period. The Federal government will have the lead on the 76 remaining sites per year. These estimates are based on historical and planned data obtained from a Superfund databa se. On average, 90 percent of RI/FS are completed within 2
- 5 years (13
- 60 mos.) of the start date. This average represents an analysis of actual and planned date s from Fiscal Year (FY) 2001 to FY 2006, grouped both by three
- year ICR periods and across th e years. The number of RI/FS that EPA expects at both Federal and state lead sites represents an average taken across each three
- year grouping for number of starts and for total time to completion. Proposed Plans The requirement to issue a Proposed Plan was added to the remedial process by SARA, (42 USC 9617(a); 40 CFR 300.430(f)(2)). This document is to be prepared by the lead agency, in consultation with the support agency, at a site after completion of the RI/F S report and prior to selection of a response action. The lead agency's primary objective in preparing and releasing the Proposed Plan is to seek public comment on the preferred alternative for addressing a problem at a site, and on the other alternatives discussed in the detailed analysis section of the RI/FS. The Proposed Plan serves as a precursor to the Record of Decision (ROD), which details the remedial action to be conducted at the site. The ROD is usually is draft form while the Proposed Plan is finalized and released for public comment. The Proposed Plan is w

ritten using information from the RI/FS report. The purpose of the Proposed Plan is to highlight the RI/FS report, provide a brief analysis of remedial alternatives under consideration, ide ntify a preferred alternative, and provide the public with information on how they can participate in the remedy selection process. In developing the Proposed Plan, the lead and support agencies first review the RI/FS report prepared for a site, identify an initial preferred alternative, and prepare a draft Proposed Plan. The lead agency's management is briefed on the draft Proposed Plan, which is then forwarded to the support agency for comments. At the end of the support agency review period, the Prop osed Plan is finalized and released to the public for comment.

### 23 CERCLA, as amended, also requires the lead agency to publish a brief notice and description of the Proposed Plan in a local newspaper of general circulation. As required by CERCLA §117(a) (4 2 USC 9617(a)), this notice includes information sufficient to provide a reasonable explanation of the preferred alternative and the other alternatives studied. This notice will also announce the availability of the RI/FS report and any planned public participation activities, especially the required Proposed Plan Public Meeting and 30
- day comment period. Finally, CERCLA §l17 requires the lead agency to offer the opportunity for a public meeting to discuss and answer questions and to obtain feedback about the RI/FS report and the Proposed Plan. The lead agency establishes a date and time for the meeting, reserves a facility, and arranges for any special needs. The lead agency also designs the meeting program, including identifying specific issues and ta sks to be addressed, preparing an agenda, identifying presenters, and rehearsing presentations. Printed materials, visual aids or graphics, and other materials are prepared and special arrangements made, such as hiring a court reporter. Finally, the meeting is held, and a transcript of the meeting notes is prepared by the lead agency. The transcript is made available to the public as required by CERCLA §117. Because the Proposed Plan typically is followed closely in time by the ROD, the total number es timated to be w ritten annually at state
- lead sites is based on data collected for RODs. Proposed Plans are completed in a discrete amount of time and are assumed not to extend beyond one year. The ROD data comes from the Superfund database and will be di scussed in detail in the following section. EPA estimates that Proposed Plans will be finalized at 10 state
- lead sites in each year of the three years covered by this ICR. Records of Decision The lead agency prepares a ROD in response to the statutory re quirements in CERCLA §l13 (42 USC 9613) for a statement of basis and purpose of the selected remedy at a site and in CERCLA §117 (42 USC 9617), which calls for a remedial action plan to be adopted and released to the public. The ROD is prepared by the l ead agency in consultation with the support agency for a site. It is the decision document used to describe the selected remedy for a site or a particular component of a site (e.g., geographic area, pathway, or source control), and to explain the rational e for the selected remedy. In addition, RODs demonstrate the lead agency's decision
- making process has been carried out in accordance with CERCLA and the NCP. RODs typically have three major sections: the Declaration, the Decision Summary, and the Respons iveness Summary. All RODs are signed by EPA Regional Administrators or the Assistant Administrator for OSWER. In addition, a representative from a state may sign a ROD. The Declaration is the formal statement (signed by the EPA regional administrator o r the OSWER assistant administrator) that affirms the selected remedy for a site is selected in accordance with CERCLA and is consistent, to the extent practicable, with the NCP. It provides a brief description of the selected remedy. The Decision Summary is the focus of the ROD. The Summary begins with a brief discussion of the site history and a detailed site description, including:

- Site area and topography,

- Adjacent land uses;

-Natural resource uses;

- Distance to nearby populations;

- General water resources, and

- Surface and subsurface features. Next, the history of state and Federal site investigations and CERCLA enforcement actions at the site are summarized. This historical summary is followed by a discussion of the community involvement activities that have been conducted for the site.

### 24 The Decision Summary summarizes the scope of the response action and the site characteristics. The site characteristics section draws on information presented in the RI/FS report and includes details on:

- Ty pes, quantity, and concentration of hazardous sub stances at a site:

- All known or suspected sources of contamination;

- All known or potential routes of migration, including the mobility, toxicity, and volume of waste;

- Lateral and vertical extent of contamination at the site; and

- Potential surface and subsurface pathways of migration. Maps illustrating the location of units or contaminants and charts of contaminant types and concentrations often are used in the site characterization section of the Decision Summary. In addition, the results of the sit e risk assessment and any significant changes made to the preferred alternative in the Proposed Plan are summarized. Another major component of the Decision Summary is the evaluation of the remedial alternatives considered for the site and identification of the selected remedy. The evaluation of alternatives section first presents a brief description of each of the remedial alternatives. Each alternative for which a detailed analysis was completed (ty pically five) is discussed. These discussions include :

- Summaries of the technology considered, such as in
- situ treatment, clean closure, or thermal treatment;

- The type and quantity of waste to be contained or treated; and

- The major ARARs and standards being met or utilized for specific components o f the waste management process. The estimated capital and O&M costs, as well as estimated implementation time of alternatives, also are presented. A comparative analysis is presented in which the remedial alternatives are evaluated based on the nine cri teria described under the RI/FS process and comments on the Proposed Plan. At the end of this analysis, the selected remedy is highlighted as a remedy that meets the statutory requirements of CERCLA and provides the best balance among the evaluation crite ria. The Decision Summary concludes with a detailed discussion of the selected remedy. The summary presents the risk levels to be attained after implementation of the remedy and summarizes the cleanup objectives for the different media at the site. Fin ally, the selected remedy section of the Decision Summary demonstrates that the selected remedy complies with the statutory requirements in CERCLA §121 (42 USC 9621), that is, the remedy will protect human health and the environment, attain Federal and state ARARs, be cost
- effective, and utilize permanent solutions and alternative treatment technologies or resource recovery technologies to the maximum extent practicable. A discussion of the extent to which the selected remedy fulfills the statutory prefere nce for treatment that reduces the mobility, toxicity, or volume of the principal threats at a site is presented in this section. The final component of the ROD is the Responsiveness Summary, which is a requirement in CERCLA §117 (42 USC 9617). This part summarizes the written and oral public comments received on the RI/FS report, the Proposed Plan, and the Administrative Record and the lead agency's responses to each major category of comments. The Responsiveness Summary not only provides decision makers with information about community preferences regarding the remedial alternatives considered for a site, but also demonstrates to the public how their comments were taken into account as an integral part of the decision making process. In preparing th e Responsiveness Summary, background research is done to identify citizen input and concerns. In this process, transcripts of the public meeting on the RI/FS report and the Proposed Plan are reviewed, major public comments are organized and summarized, an d the lead agency's responses to these comments are prepared. The level of effort to be devoted to this section of the ROD varies, depending in part on the number,

### 25

length, and complexity of comments and the number of policy issues outstanding at a site. For the purposes of this ICR, it is estimated that 20 RODs will be completed annually at state
- lead sites over the three
- year ICR period, while 80 RODs will be completed annually by the Federal government. This average is based on data in a Superfund database concerning the actual number of RODs issued between FY 2007
- 2010 and those planned through 2015. The average takes into account that planned numbers routinely are higher than actual numbers. Applicable or Relevant and Appropriate Requirements SARA added a requirement to CERCLA §121(d) (42 USC 9621(d)) that all remedial actions must be in compliance with promulgated state ARARs that are more stringent than Federal ARARs. To this end, the current revisions to the NCP require states to identify potential state ARARs for all Federal, state or Federal facility
- lead sites. States are not reimbursed for any costs associated with researching and identifying ARARs for a site. Potential state ARARs are to be identified as early in the RI/FS process as possible. Therefore, the estimate of sites where ARAR identification is necessary is based on RI/FS start data from a Superfund database. The average for each type of site is taken across actual and planned dates for RI/FS starts. It is estimated that a tota l of 95 sites will require ARAR identification each year. Administrative Records SARA amended CERCLA §113 to require that an Administrative Record be established to document the basis for selection of response action. The record must be made available to the public at a location near the site (42 USC 9613 (1)). As a result, two records, one near the site and one at the lead agency office, are compiled and maintained at each remedial site. In developing the records, an appropriate location for the record must be identified. This location must be publicly accessible. Then, documents included in the record must be maintained by updating information as necessary, and verifying the information is available that should be included in the record. The information record will be maintained as long as site remediation continues and for as long as is needed in the event there is litigation. Because remedial responses often last longer than three years, the record keeping associated with remedial responses typica lly will be maintained for more than three years. The Administrative Record must be maintained at all active Superfund sites each year. For the purposes of this ICR, active sites are those that have not yet achieve the Construction Complete milestone. These sites may have studies pending, design and study underway, or construction underway. Based on historical program data, EPA estimates there to be approximately 530 active Federal and state
- lead Superfund sites. For RI/FS, RD, and RA activities, stat es have historically had the lead on 20 percent of sites. This percentage of active sites also is applicable for the revised CIP, fact sheets, and focus groups. Therefore, it is estimated that the state will maintain the administrative record at 106 site s each year.

### 26

Initial Community Involvement Plan (CIP)/Revised CIP Community Involvement Plans are developed at remedial sites to identify community concerns and to select techniques and approaches to use in addressing these concerns. The initial CIP dev eloped for a site presents the community involvement program that is to be followed during the RI/FS stage of the remedial phase. The NCP requires the CIP be completed and in place before field work begins for the RI. However, as the Agency seeks to acco mp lish RI field work during pre
- remedial actions to expedite cleanups, EPA is finding it necessary to begin its community involvement activity, including preparation of the CIP, very early in the pre
- remedial phase. The NCP also requires that EPA review i ts CIP prior to the Remedial Design/Remedial Action phase, and make any changes necessary to accommodate changes in the community. The initial steps in the preparation of CIPs involve conducting a review of the site and the surrounding community. Lead a gency technical personnel summarize the problems at a site, the origins of those problems, and potential steps for addressing the problems. As part of this process, lead agency files on the site are reviewed and local newspaper files are searched. Once a basic understanding of the site and previously performed activities is established, community involvement personnel from the lead agency conduct interviews with local community members to better determine community concerns and the level of community knowledge of site activities. In this process, a contact list is prepared, interviews are scheduled and conducted, and the results of the intervie ws are summarized. This process also includes the use of intervie ws for the purpose of establishing baseline mea sures of citizen concerns and attitudes from which changes can be measured, as well as to gain additional information that will help in the preparation of the CIP. Once the background research is completed, a community involvement program is designed. This program may recommend such activities as distributing information brochures and fact sheets that explain Superfund program activities and the role of the lead agency in the remediation of Superfund sites. Small group meetings between lead agency staff, citizens, and local officials may be held to promote an informal exchange of ideas. To maximize the potential to bring about improvement in government services, EPA will utilize telephone interviews of fact sheet recipients and meeting attendees to asses s the effectiveness of specific outreach products. EPA may also use focus groups to gather citizen input. At some sites, formal community groups may be established that provide regular involvement and input to site activities. In some cases, updates or comprehensive CIP revisions are undertaken at specific benchmarks in the Superfund cleanup process, such as after a record of decision (ROD) is signed, at Explanations of Significant Differences or ROD amendments, when the remedial action has begun, or at the time of the five
- year review. Others are updated or revised according to a timetable, such as every three or five years. The decision to undertake a comprehensive revision of the CIP sometimes is made based on a change in the level or nature of comm

unity interest. When there is a high level of interest at a site, the CIP should be revised regularly so that the document continues to reflect current conditions and community interests. On the other hand, it may be time to conduct a comprehensive CIP revision when community interest has waned over a long period of time. It also may be appropriate to revise a CIP after demographic, economic, or political change in the community. A CIP revision is in order w hen CICs believe that a change their strategy on i nvolving communities may be necessary. Since the Initial CIP is generally developed concurrent with the RI/FS, the estimated number of sites at which the state will conduct an RI/FS each year is applied to the Initial CIP. Therefore, EPA expects 19 CIPs to be completed by states each year of the three
- year ICR period. Federal
- lead sites are expected to complete 76 initial CIPs each year. Assuming CIPs are revised every five years for all active Superfund sites, Superfund data indicates that states have the lead on approximately 106 active Sup erfund sites; therefore, a rough estimate is that each year 21 of these sites will require a CIP revision. EPA estimates that CIPs will be revised at 85 active Federal
- lead Superfund sites each year.

### 27

Fact Sheets The lead agency provides fact sheets to communities at various points, both pre and post Construction Com pletion, in the Superfund remedial process. The number and frequency of fact sheets developed varies depending on community interest, complexity of remedial technologies, PRP/enforcement iss ues, and the extent of relocation and reuse potentials. Fact sheets may describe the details of a specific technology used, the physical changes that may occur at the site, the extent of contamination and health risks, the status of enforcement actions an d negotiations with PRPs, etc. The lead agency develops fact sheets on an “as needed” basis. These fact sheets may be mailed to a list of interested community members. EPA estimates that the states are the lead agency for 106 active Superfund sites and, thus, are expected to write fact sheets for these sites. A group of experienced EPA Headquarters and Regional Community Involvement staff estimate that an average of four (4) fact sheets will be completed at each active Superfund site. Because of the site
- specific need for fact sheets, it is anticipated that some sites will generate far more than four (4) fact sheets in a single year and other sites will require far fewer. Focus Groups For this ICR, focus groups are defined as meetings or sessions the purpose of which is to obtain community input and in which the lead agency asks the community specific questions. These groups typically involved a small select group of community members who are gathered to provide feedback from the community perspectiv e on particular on
- going issues and concerns. A group of EPA Headquarters and Regional Community Involvement staff provided information and estimates for this analysis. EPA estimates that focus groups will be conducted an average of four (4) times per ye ar at 1 percent of active sites (one [1] at state
- lead sites, four [4] at Federal
- lead sites). Workshops This ICR defines workshops as meetings or sessions that are open to the general public and w hose subject matter is broad in scope. These workshops ar e often used as planning tools in which specific broad overview questions are asked of the community to gather ideas about their visions for the site and potential future uses. EPA headquarters and regional Community Involvement staff estimates that a workshop is conducted at 2 percent (currently ~10 sites) of all active sites each year. Since the state has the lead on 20 percent of active sites, EPA estimates that the state will prepare and conduct a workshop at two (2) sites annually. EPA estimates that it will conduct a workshop at eight (8) Federal
- lead sites each year.

### 28

Technical Assistance Grant Application/TAG Management SARA amended CERCLA §117(e) to provide for Technical Assistance Grants (TAGs) to eligible community groups for an initial grant up to $50,000. The purpose of these grants is to give communities that are affected by Superfund sites the opportunity to obtain expert information and consultation about the site. The TAG allows community groups to hire an independent advisor who can he lp them understand various technical aspects of the site, such as characteristics of the contamination, the proposed remedies, the remedial design, the technical aspects of the remedy, the health risk and analysis, and site construction. TAGs may be renew ed to facilitate public participation throughout the Superfund remedial process. Community groups apply for TAGs and manage those that they already have. TAGs are processed and granted by the Federal government. There is no state burden or cost for TAGs . EPA Community Involvement staff estimate that 10 TAG applications will be filed and 75 maintained each year. Satisfaction Surveys Satisfaction surveys are used by EPA to gather community input about EPA’s community involvement efforts. These surveys consist of up to ten questions asking community members to provide opinions and to rank EPA’s community interactions, the level of knowledge citizens have gained about the site and issues, how citizens learned information about the site, and the desires of the community for how they wo uld like to interact with EPA. The information gathered in these satisfaction surveys helps EPA improve its community involvement activities and relationships with communities at Superfund sites. EPA estimates that these surveys will be completed at five (5) active Superfund Federal
- lead sit es each year. The template for this survey accompanies this ICR
. (ii) Respondent Activities In complying with reporting and record
- keeping requirements at state
- lead sites, state employees may need to:

- Read instructions;

- Plan activities;

- Receive training;

- Gather information;

- Conduct tests, investigations, and studies;

- Write documents;

- Process, compile, and review information for accuracy and appropriateness;

- Complete written forms or other paperwork;

- Substantiate claims of confidential business information;

- Record and disclose information; and

- Store, file, and maintain the information. In identifying ARARs at Federal, state, and Federal facility
- lead sites, state employees may need to:

- Gather information on ne w state laws and regulations;

- Process, compile, and review information for accuracy and appropriateness;

- Record and disclose information; and

- Store, file, and maintain information. In participating in the remedial phase, community members may disclose information to state and EPA personnel during interviews. Community members may perform any or all of the following activities:

- Participate in interviews;

- Participate in focus groups;

- Participate in workshops;

### 29 - Apply for a Technical Assistance Grant (TAG)

- Manage a TAG; and

- Respond to surveys. 5. THE INFORMATION COLLECTED
- AGENCY ACTIVITIES, COLLECTION METHODOLOGY, AND INFORMATION MANAGEMENT 5(a) EPA Activities

 **Superfund Site Evaluation and Hazard Ranking System** EPA region offices review and manage sites assessed under Superfund by States and Tribes, and provide oversight for State and Tribal site assessment cooperative agreements. EPA generally performs the following duties for each of the site assessment activities covered under this ICR:

- Coordinate site specific work and review draft doc uments and reports;

- Prepare summary reports and decision documents;

- Identify stakeholders and communicate site assessment plans and progress;

- Respond to information requests; and

- Perform data management activities to record and track assessments.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  EPA will collect the requested information using standardized reports and record keeping appropriate to support cost recovery. The grants information is entered into IGMS , the Agency’s database for tracking the status of grant/cooperative agreement actions. Financial information is entered into IFMS, the Agency’s database for tracking financial management.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)**  Agency activities that relate to the information gathered from states are predominantly oversight functions at state - lead sites to ensure that the Superfund sites are being addressed according to CERCLA and to EPA’s current policies. In this role, the Agency may obtain, review, and maintain the information gathered by states. The Agency also reviews the state ARARs at all Superfund sites. A standard 10 percent of annual hours is applied to Federal oversight of the following state activities: RI/FS, Proposed Plans, RODs, ARAR evaluation, and initial and revised CIPs. A group of experienced EPA headquarters and regional Community Involvement employees provided the oversight hours estimates for all other activities: Administrative Record, fact sheets, focus groups, and workshops. At all Federal
- lead sites, the Agency conducts the following activities: maintaining the Administrative Record, initial CIP, revised CIP, fact sheets, focus groups, workshops, TAG applications, TAG management, and satisfactio n surveys. 5(b) Collection Methodology and Management

 **Superfund Site Evaluation and Hazard Ranking System** Data gathered during the site assessment process fall into three main categories: historical; field related; and HRS related. At each phase of assessment, data from these broad categories are collected and analyzed in order to screen out sites that do not need to be addressed by the Superfund program. As a site moves from one phase to another in the site assessment process, it must satisfy an increasing number of data requirements for the HRS model. Sites may be screened out of the site assessment process based on a Pre - CERCLIS screening to determine whether a potential hazardous waste site shoul d be added into CERCLIS for further evaluation or response. In addition, sites

### 30

may also be screened out based on the HRS score generated; a referral to other Federal and State programs; or a referral to the removal program. Following entry of a site disc overy into CERCLIS, the PA process is initiated. During the PA, professional judgment is used to make assumptions for unavailable data. Information collection at this phase is accomplished mo stly from the desktop by reviewing historical documents and conducting telephone interviews. The majority of the data collected is historical information and target information for the HRS model. A site drive
- by may also be conducted to verify the site location and status. During the PA, the HRS is applied through development of a preliminary HRS score. A PA report is the final product of this phase. Information collected during the PA is incorporated into subsequent work. A site that is recommended for continued Superfund evaluation after PA completion proceeds to the SI phase. Data collection goals for this phase are similar in scope to the PA with the addition of detailed field data (e.g., site samples). During this pha se, a field team conducts an on
- site visit and sampling. Site sampling is limited in scope; generally, about 15 samples are collected per site. The media selected for sampling depends on the perceived threat and may include all or some of the following: ground water, surface water, sediment, soil, and air. Source samples may also be taken when deemed necessary. Detailed chemical analysis and data validation is performed on each sample taken. During the SI, the HRS model is applied by revising the preli minary HRS score developed during the PA. An SI report is the final product of this phase. Information collected during the SI is incorporated into subsequent assessment work. A site that is recommended for continued investigation may have an ESI performed. At this stage, specific information is usually gathered for the pathway of greatest concern. The goal of this investigation is to test remaining theories about the nature and extent of contamination proposed in the SI. Additional field data that ar e collected usually require specialized techniques or equipment (e.g., installation of monitoring wells, geophysical surveys). Data generated are used to modify the preliminary HRS score developed during the SI. An ESI report is the final product of this phase. Information collected during the ESI is incorporated into subsequent assessment work. A site that generates a preliminary HRS score of 28.50 or greater after all assessment work is com plete is eligible for proposal to the NPL, although additional factors are considered before EPA moves forward with proposing a site. To propose a site, a detailed and defensible HRS Scoring Package must be prepared. This phase of data collection brings together all of the information collected during the site asse ssment process. The HRS Package is thoroughly and meticulously referenced. The final product of this phase is the final HRS score. A public docket for a proposed site is maintained by EPA to provide an opportunity for all interested parties to examine and comment on the HRS Package before it is finalized in the Federal Register. In order to expedite the data management effort and minimize the burden, EPA developed “Quickscore” software for use as an automated site scoring tool under the revised HRS . Quickscore includes a user’s manual, help screens, HRS score sheet calculation package, and a computerized option for site score generation. In addition, EPA has sought to minimize the burden of data collection requirements by making resources avai lable to the respondents through the use of EPA contractors. EPA will continue to provide training to States and Tribes on a yearly basis through a national training program. To facilitate the HRS scoring effort, EPA has, wherever possible, included tabl es to minimize the level of effort necessary for data collection. EPA’s assessment process allow s for the integration of traditional site assessment activities to facilitate continuous assessment for high
-priority sites until all the necessary data are collected. Combining some phases of the site assessment process will often reduce the level of effort expended on the duplication of similar data
- gathering activities. Exhibit 4 presents EPA’s Integrated Assessment process. This integrated approach provides:

### 31  Prom

pt risk reduction through early action (removal or cleanup activities);  Continuous process for assessing site
- specific conditions and the need for action;  Appropriate cleanup of long
- term environmental problems;  Cross
-program coordinatio n of response planning;  Early initiation of enforcement activities; and  Early public notification and participation.

The Site Reassessment represents the gathering and evaluation of new information on a site previously assessed under the Federal Superfund Program to determine whether further Superfund attention is needed. The scope of work for a Site Reassessment activity is flexible, but will usually represent a component of a traditional site assessment action. As such, it serves as a supplement to previous assessment work, and not as a replacement for traditional assessment activities (e.g., PA, SI). All data collection activities require the maintenance of file information. The final report for each phase of the site assessment process is only part of the documentation of a site. All relevant site information collected or generated during the investigations should be securely stored and accurately tracked for future reference. This information is critical for the preparation of any final HRS packages and for future site disposition. Each agency performing site assessments or involved in the decision
- making process of a site should maintain a file of site data.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response**  **Actions** EPA will conduct activities in connection with the acquisition, analysis, storage, and utilization of the requested cooperative agreement and Superfund State Contract
- related information and financial data. This information and financial data are reviewed in accordance with the requirements of 40 CFR Part 35, Subpart O. Initial Field In vestigation (Recon) Report Received/ Release Identified Exhibit 4: EPA ’ s Integrated Assessment Process

### 32 Superfund recipients must retain records for 10 years following the submission of the final Financial Status Report, and must retain those records longer if an enforcement acti on is ongoing. This ensures that response action information will be available to support EPA litigation efforts to recover Superfund costs from responsible parties. The Agency also conducts periodic on
- site reviews to ensure recipient compliance with ap plicable requirements.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** The information collection methodology varies depending on the type of activity being conducted. For example, an RI/FS requires many more hours than other acti vities because it involves field work and sampling. In contrast, evaluation of ARARs involves systematic and routine research. A large component of Proposed Plans and RODs is the actual preparing and finalizing of the document. States provide informatio n to EPA Regional Offices in the form of document copies. Regions revie w the documents to ensure consistency with the NCP. Regions and states use various media avenues (e.g., local newspaper announcements, mailings, etc.) to notify the public about meeti ngs, focus groups, and workshops. The regions and states may also communicate with Community Advisory Groups (CAGs) and other involved citizen groups. Phone calls and office hours are other means by which the governments communicate with communities. Th e activities reflected in this ICR do not lend themselves to automation because of the decentralized nature of each remedial activity. These activities are site
- specific and, therefore, are not conducive to mass data collection efforts. The NCP does not specify a particular method of accomplishing information collection; the use of improved information technology is not prohibited in any way.

### 33

5(c) Small Entity Flexibility

 **Superfund Site Evaluation and Hazard Ranking System**  Except in circumstances where a small business is a potentially responsible party (PRP) or may provide some original information about a specific site, small businesses are not burdened by the collection of data for this program.
 **Cooperativ e Agreem**  **ents and Superfund State Contracts for Superfund Response Actions** There are no small businesses affected by this information collection. Small Governmental Jurisdictions are affected, but the burden is minimal, and steps have been taken to reduce the burden imposed by this information collection. As 40 CFR Part 35, Subpart O is a fully
- funded regulation, all burden imposed by the regulation is required in order for recipients to obtain and manage financial awards.

 **National Oil and Hazardous Substa nces Pollution Contingency Plan (NCP)**  Information collection from small entities (individual community members, community organizations, etc.) is primarily done on a voluntary basis. Since these respondents are providing information voluntarily, the Feder al government is not placing any undue burden on small entities and does provide plenty of flexibility. 5(d) Collection Schedule

 **Superfund Site Evaluation and Hazard Ranking System** The site assessment process is intended to be a flexible method for determining priorities among releases or threatened releases of hazardous substances for the purpose of determining if further investigation is necessary. Site assessment information collection does not occur on a regu larly scheduled basis. The frequency of collection is driven by the schedule established in Section 116(b) of CERCLA. Section 116(b) requires an HRS evaluation (if warranted) within four years of the site's entry into CERCLIS. 14 For sites brought to EPA’ s attention via a citizen’s petition, Section 105(d) of CERCLA requires completion of a PA, or an explanation of why a PA is not appropriate, within one year after receiving the petition.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund**  **Response Actions** The collection schedule for this information relating to cooperative agreements and Superfund State Contracts is variable depending on such factors as: date of applications, magnitude of efforts, and project periods, etc.

 **National Oil an d Hazardous Substances Pollution Contingency Plan (NCP)**  Information is collected according to the sequence of remedial activities at Superfund sites: RI/FS, ARAR evaluation, Proposed Plan, ROD, and initial Community Involvement Plan (CIP). Other activitie s are conducted throughout the remedial process as needed. These include maintenance of the Administrative Record, revising the CIP, issuing fact sheets, processing Technical Assistance Grants (TAGs), gathering community satisfaction surveys, and conducti ng focus groups and workshops with community members. The frequency of these activities will depend on many site
- specific factors such as complexity of clean
- up technologies, level of community interest, and duration of each of the remedial stages.

6. ESTIMATING THE BURDEN AND COST OF THE COLLECTION 6(a) Estimating Respondent Burden

 **Superfund Site Evaluation and Hazard Ranking System** EPA estimat es an annual average of 60 States and Tribes will conduct the site assessment activities described in this ICR. The annual burden for respondents is a function of the number of State
- and Tribal
- lead activities performed each year. The estimated total annual burden for State and Tribal authorities to conduct these activities is approximately 121,681 hours. This estimate was calculated by multiplying the estimated average annual number of State
- and Tribal
- lead activities projected from FY 20 12 through FY 201 4 by the average hours needed to perform each activity. Exhibit 5 provides detailed information on the estimated annual respondent burden (calculated as a weighted average based on information provided by EPA regions ).

Exhibit 5: Annual Respondent Burden of Superfund Site Evaluation and HRS Respondent Activities Estimated Hours Per Activity 1 Estimated Annual Number of

State/Tribal Activities 1 Total Annual National Hours by Activity Pre - CERCLIS Screening 89.19 268 23,904 P reliminary A ssessment (PA) 154.52 140 21,633 Site Inspection (SI) 605.68 58 35,129 Integrated Assessment (IA) 347.00 2 694 Expanded Site Inspection (ESI) 816.10 22 17,954 Site Reassessment 218.66 70 15,306 HRS Package 784.44 9 7,060 TO TAL 569 121,681 1 Weighted average based on activity hours provided by the EPA Regions To reduce the burden on respondents, EPA has streamlined the process of screening sites to ensure that sites are assessed as efficiently and inexpensively as conditions allow. Sites not requiring Federal action are screened out of the process early, thus avoiding lengthy and more expensive evaluations. For example, only about f our percent of the sites in the site assessment process have been listed on the NPL. 15 Exhibit 6 provides an illustration of the site assessment screening process. The process is portrayed as a funnel to show

how the number of respondent activities performed generally decreases as sites progress down the funnel and are screened out of the process. Depending upon how far a particular site progresses through the site assessment pro cess, the burden per site may range on average from 89 hours (average for conducting pre
- CERCLIS screening and no other work) to 2,450 hours (cumulative average for conducting pre
- CERCLIS screening, PA, SI, ESI, and HRS package work).

### 35 Exhibit 6: Site Assessment Screening Process *Historically includes about four percent of all sites in the CERCLIS site assessment inventory.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  Exhibit 7 , “Total Respondent Burden,” documents the computation of individual burdens for providing the information required for the application and administration of each type of cooperative agreement and each Superfund State Contract included in this ICR. The individual burden is e xpressed under a heading believed to be consistent with the concept of burden under the Paperwork Reduction Act. Responses to this information collection are mandatory, as they are required to properly manage and administer the funds awarded under cooperative agreements and Superfund State Contracts.

*Amendment respondents are assumed to have only 1/3 of the burden imposed as Full respondents, since the process of amending is not as extensive as it is for a new application for a CA The 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. A “unit” burden is the burden incurred by a respondent for performing a cooperative agreement specific activity. States incur burdens under an estimated 674 cooperative agreement and Superfund State Contract activities per year for reporting, certifications, schedules, notifications, assurances, and record keeping activities. The estimated burden is incurred by activities under the following types of Coop erative Agreements/Superfund State Contracts and other requirements:

 Pre - Remedial Cooperative Agreements;  Remedial Response Cooperative Agreements;  Enforcement Cooperative Agreements;  Removal Cooperative Agreements;  Core Program Cooperative Agreements;  Support Agency Cooperative Agreements;  Superfund State Contract;  Conclusion of Superfund State Contracts;  Consolidated Funding Cooperative Agreements;  Conclusion of the Cooperative Agreements; and  Records Retention. The estimated average burden associated with each Cooperative Agreement/Superfund State Contract/Other requirement is discussed below and summarized in Exhibit 7 , “Total Respondent Burden.” The estimated burden associated with Pre
- Remedial Cooperative Agr eements represents the number of hours that are spent in identification of environmental results, research, data collection, analysis, negotiation, preparation, and post
- award monitoring of the Pre
- Remedial Cooperative Agreement. EPA estimates that approx imately 46 (15 new respondent CAs and 31 amended respondent CAs) Pre
- Remedial Cooperative Agreements involving States, Tribes, or political subdivisions, will be in place each year. EPA estimates that an average of 12 hours are necessary to prepare all th e plans, compliance documents, lists and schedules required in the application for this type of Cooperative Agreement within Subpart O. The estimated burden associated with Remedial Response Cooperative Agreements represents the number of hours that ar e spent in identification of environmental results, research, plan preparation, data collection, analysis, negotiation in preparing the materials required for, and post
- award monitoring of Remedial Response Cooperative Agreements. EPA estimates that appro ximately 81 (29 new respondent CAs and 52 amended respondent CAs)

### 38

Remedial Response Cooperative Agreements, which involve States, Tribes, and political subdivisions, will be in place each year. EPA estimates that an average of 21 hours is necessary to pre pare all the materials required in an application for this type of Cooperative Agreement. Those materials include: a project narrative, which includes much more site
- specific information than a project narrative for a Pre
- Remedial Cooperative Agreement; c om pliance documents and certifications; CERCLA assurances; and notifications. The majority of the burden under this Cooperative Agreement is associated with the preparation of the schedule of deliverables. Though the format of that schedule is fairly standard, the planning and negotiation involved can be time consuming. The estimated burden associated with Enforcement Cooperative Agreements represents the number of hours that are spent in identification of environmental results, research, plan and certification documentation preparation, such as the quality assurance plan, data collection, analysis in the preparation of materials involved in acquiring and operating within an Enforcement cooperative agreement. EPA estimates that an average of 23 (9 new respondent CAs and 14 amended respondent CAs) Enforcement Cooperative Agreements will be in place each year. EPA also estimates that 32 hours are needed to fulfill the requirements imposed by this type of Cooperative Agreement. Those requirements includ e: creating the site description; creating the site specific statement of work; producing the statement designating lead site project manager; creating the site specific health and safety plan; producing the quality assurance plan; developing the schedule of deliverables; and producing a copy of the applicable state, local, or tribal statutes. The majority of the burden is imposed by the creation of the site specific statement of work, the quality assurance plan, and the schedule of deliverables. The es timated burden associated with Removal Response Cooperative Agreements represents the number of hours that are spent in identification of environmental results, research, plan preparation, data collection, analysis, negotiation in preparing the materials r equired for, and post
- award monitoring of, a Removal Response Cooperative Agreement. EPA estimates that approximately 7 (4 new respondent CAs and 3 amended respondent CAs) Removal Response Cooperative Agreements, which involve States, Tribes, and politica l subdivisions, will be in place each year. EPA estimates that an average of 32 hours is necessary to prepare all the materials required for this type of Cooperative Agreement. Those required materials include: a site description; a site specific stateme nt of work; a statement designating lead site project manager; a site specific community relations plan; a site specific health and safety plan; a quality assurance plan; a schedule of deliverables. Program experience has shown that the majority of the burden imposed under the requirements for this type of Cooperative Agreement can be attributed to the development of the schedule of deliverables and the quality assurance plan. The estimated burden associated with Core Program Cooperative Agreements represents the number of hours that are spent in identification of environmental results, research, data collection, analysis, negotiation in preparing the materials required for, and post
- award monitoring of a Core Program Cooperative Agreement. EPA estimates that 43 (18 new respondent CAs and 25 amended respondent CAs) Core Program Cooperative Agreements, which involve States, Tribes, and political subdivisions, will be in place each year. Superfund program experience indicates that, on average, about 23 hours are needed to fulfill the requirements imposed by this type of Cooperative Agreement. Those requirements include preparing a statement of work, and a background statement. Those two requirements are responsible for the majority of burden attributed to Core Program Cooperative Agreements. The estimated burden associated with Support Agency Cooperative Agreements represents the number of hours that are spent in identification of environmental results, research, data collection, analysis, negotiation in preparing the materials required for, and post
- award monitoring of a Support Agency Cooperative Agreement. EPA estimates that approximately 67 (23 new respondent CAs and 44 amended respondent CAs) Support Agency Cooperative Agreements, which involve St ates, Tribes, and political subdivisions, will be in place each year. EPA estimates that an average of 11 hours are needed to prepare all the materials required for this type of Cooperative Agreement. The majority of the burden imposed by a Support Agenc y Cooperative Agreement can attributed to the development of the required statement of work.

### 39 The estimated burden associated with the contents of a Superfund State Contract represents the number of hours that are spent in identification of environmenta l results, research, data collection, analysis, negotiation, and preparation of the Superfund State Contract each year. EPA estimates that approximately 24 (6 new respondent CAs and 18 amended respondent CAs) Superfund State Contracts are in place each ye ar. The Superfund grants program workgroup estimates that about 27 hours are needed to meet the burden imposed by the requirements under a Superfund State Contract. Those requirements include: general authorities; purpose statement; site description; statement to follow

guidance; statement of work; schedule of deliverables; SPOC; CERCLA assurances; list of Support Agency Cooperative Agreements; sanctions for failure to comply with the terms of the Superfund State Contract; site access; joint inspection of the remedy; exclusion of third party benefits; State review; and a list of responsible party activities. The estimated burden associated with the Conclusion of a Superfund State Contract represents the number of hours that are spent in assembling and rec onciling financial data, identifying any outstanding contractual issues, assembling relevant agreement data deliverables and other documentation, coordinating with USEPA personnel in the disposition of equipment and other acquisitions under the Superfund S tate Contract, determining final cost shares and preparing the site for the operation and maintenance. EPA estimates that approximately 22 (22 new respondents and 0 amended respondents) Superfund State Contracts are concluded each year. The Superfund Sub part O Workgroup estimates that an average of 9 hours is needed to meet the burden imposed by the requirements under a Superfund State Contract. Those requirements include: general authorities; purpose statement; site description; statement to follow guid ance; statement of work; schedule of deliverables; SPOC; CERCLA assurances; list of Support Agency Cooperative Agreements; sanctions for failure to comply with the terms of the Superfund State Contract; site access; joint inspection of the remedy; exclusio n of third party benefits; State review; and a list of responsible party activities. The estimated burden associated with Consolidated Funding Cooperative Agreements represents the number of hours that are spent in identification of environmental results, research, data collection, analysis, negotiation, and preparation of Consolidated Funding Cooperative Agreements each year. EPA estimates that approximately 8 (1 new respondent CA and 7 amended respondent CAs) Consolidated Funding Cooperative Agreements are in place each year. EPA estimates that approximately 45 hours a year are necessary to meet the requirements of a Consolidated Funding Cooperative Agreement. This type of agreement is composed of a Pre
Remedial, Core Program, and Support Agency Cooper ative Agreement. The estimated burden associated with the Conclusion of a Cooperative Agreement represents the number of hours that are spent in assembling and reconciling financial data, identifying any outstanding contractual issues, assembling relev ant data deliverables and other documentation, coordinating with USEPA personnel in the disposition of equipment and other acquisitions under the agreement, determining final cost shares and preparing the site for the operation and maintenance. EPA estimates that approximately 15 (15 new respondent CAs and 0 amended respondent CAs) Cooperative Agreements are concluded each year. The EPA Superfund Subpart O Workgroup estimates an average of 13 hours are needed to meet the burden imposed by the requirements under a Cooperative Agreement. Those requirements include: general authorities; purpose statement; site description; statement to follow

guidance; statement of work; schedule of deliverables; SPOC; CERCLA assurances; list of Support Agency Cooperative Agreements; sanctions for failure to comply with the terms of the Cooperative Agreement; site access; joint inspection of the remedy; exclusion of third party benefits; State review; and a list of responsible party activities. The estimated burden associated with the Records Retention requirements represents the number of hours that are spent each year beyond the 10
- year (Superfund) retention requirement for record maintenance, storage, and any document requests that would be made throughout the year. All cooperative agreements must meet these Records Retention requirements, and incur the resulting burden. EPA estimates that approximately 337 (142 new

### 40

respondent CAs and 195 amended respondent CAs) Cooperative Agreements will be in place each year. Superfund program experience indicates that an average of 6 hours will be required each year to meet the burden imposed by this regulation’s Records Retention requirements.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** Responde nt burden estimates are calculated from a combination of sources: historic and projected data from Superfund databases, contract records, consultation with EPA headquarters and regional staff, and information contained in the 2007 version of this ICR. Bur den hours are estimated for the number of hours expected annually for each activity. The annual hours per activity figure is multiplied by the number of sites expected to be engaging in the activity every year. This calculation gives the total annual hours for all sites by activity. All burden hours, with the exception of ARARS, placed on states refer to only activities conducted at state
- lead sites. All burden hours placed on communities refer to activities that are conducted at all Federal and state
- l ead sites. The estimated number of respondents reported for this information collection is 11,659. This number is the sum of all state
- lead activities, 409, and people participating in community activities at all sites, 11,250. The estimated number of re sponses is 12,977. This is the sum of state responses, 727 state
- lead activities at all sites each year, and community responses, 12,635 people participating in all activities at all sites. (i) State Burden Hours The total hours for an RI/FS is assumed to consist of 80 percent contractor work and 20 percent government work. The total contractor hours for an RI/FS project, 4,200 hours, is calculated from Office of Superfund Remediation and Technology Innovation (OSRTI) contract records from 1996 through 2006. Data for costs billed as direct labor across all projects and years provides information about the number of hours spent on an average RI/FS. Burden hours can be divided among different labor categories based on contract records: 62 percent profes sional labor, 30 percent direct labor, 4 percent clerical labor, and 4 percent technical labor. Total contractor hours per RI/FS is estimated to be 4,200 hours per year, which is estimated to account for 80 percent of the hours for an RI/FS. The remaining 20 percent of RI/FS work, 1,050 hours, is done by the state government. Therefore, the total annual time devoted to a single RI/FS is estimated to be 5,250 hours. This ICR estimates that 19 state
- lead sites will be in the process of conducting an RI/FS every year. The total annual burden hours is 99,7 50 ( Exhibit 8 ). Total burden hours for each Proposed Plan is estimated to be 80 hours. This figure covers the time taken for w riting, printing, notification, and distribution of the Proposed Plan. This estimate remains the same from the previous ICR renewal. Since Proposed Plans are expected to be completed at 20 state
- lead sites each year, a total annual estimate of burden is 1,600 hours. The hours required to complete a ROD are highly variable across the Superfund program given site complexity and enforcement issues. The burden hours for a ROD are assumed to include the time needed for writing, reviewing, negotiating, and obtaining concurrence. The ROD finalization process is one that takes quite a lot of time and energy. The estimates are based on consultation with EPA staff experienced in w riting RODs and involved in writing the ROD guidance document (“A Guide to Preparing Superfund Proposed Plans, Records of Decision, and Other Remedy Sele ction Decision Documents,” EPA 540
- R- 98
- 031, OSWER 9200.1
- 23.P, July 1999). Experience with very complex and more straight
- forward RODs was used in calculating an average value for ROD burden hours. For the purpose of this ICR it is estimated that the av erage ROD requires a total of 1,300 hours. This estimate is based on a nine
- mo nth time frame in which one full
- time employee dedicates 50 percent of work time to the ROD for a total of 720 hours, and, two full
- time em ployees dedicate 20 percent of work ti me for a total of 576 hours. The former employee is typically the Remedial Project Manager (RPM) for the site and the latter two em ployees consist of policy analysts, attorneys and managers. This ICR estimates that RODs will be completed at 20 state
- lead sites each year; thus, the estimated total annual ROD burden to states is 26,000 hours. The total estimated annual burden for identification of ARARs is 33 hours at each Federal, state or Federal

### 41

facility
- lead site. This estimate is the same as the ARAR estimate in the previous version of this ICR. The figure is also confirmed by EPA staff experienced in evaluating ARARs. ARARs are expected to be evaluated at 95 sites annually, resulting in an estimated burden of 3,135 hours. The establishm ent and maintenance of one site’s Administrative Record is estimated to take 40 hours annually. Since states are estimated to have the lead on 106 active Superfund sites, EPA expects states to spend 4,240 total hours on Administrative Records. This estim ate is provided by a group of experienced EPA headquarters and regional staff. Total estimated annual burden hours for each initial and revised CIP are 200 and 100, respectively. Initial CIPs are estimated to be completed at 19 state
- lead sites each year for a total annual burden of 3,800 hours. Revised CIPs are estimated to be completed at 21 state
- lead sites each year for a total annual burden of 2,100 hours. These hours are estimated by a group of EPA headquarters and regional staff experienced in th e development and revisions of CIPs. EPA estimates that each fact sheet will require an average of 40 hours of work per year. This estimate is the result of discussion by a group of experienced EPA headquarters and regional Community Involvement staff. An average of four (4) fact sheets are expected at each of the 106 estimated state
- lead active sites. Therefore, fact sheets will require a total annual estimate of 160 burden hours at each site. EPA estimates that states will issue fact sheets at 106 ac tive sites per year. Thus, the total estimated annual burden hours for fact sheets is 16,960. The estimated time that each focus group session will require of the state is 30 hours. This includes preparation for the meeting and attendance. EPA expects the state to conduct four (4) focus group sessions at one site in each year, resulting in a total annual estimated burden of 120 hours. These estimates are provided by a group of experienced EPA Community Involvement staff. The estimated annual burden for each workshop is 80 hours. EPA estimates that the state will be conducting one (1) workshop at two (2) sites in the course of one year and will, thus, devote 160 hours to workshop efforts. These estimates are based on the knowledge of EPA Community I nvolvement staff experienced in preparing and conducting workshops at Superfund sites.

The Paperwork Reduction Act (PRA) requires the inclusion of information gathering activities in which the community participates. These activities are those for which information is expressly collected from community members. The PRA (5 CFR part 1320, “Controlling Paperwork Burdens on the Public, FRN 8/29/1995, Sect. 1320.3 (h)(8)) excludes the following activities from the definiti on of information for the purpose of Information Collection Requests: attendance at public informational meetings or briefings, response to comments on EPA documents, participation in community groups for which EPA is not a sponsor, reading fact sheets, an d making use of EPA open office hours. This ICR records estimated burden hours for community members for initial and revised CIP interviews, participation in focus groups and workshops, TAG application and management, and completion of satisfaction survey s. All estimates are provided by a group of experienced EPA Headquarters and Regional Community Involvement Staff. EPA estimates that 40 people will be interviewed for one hour each at 95 Federal and State lead Superfund sites each year for initial CIPs. The total annual estimated burden for initial CIP interviews at all sites is 3,800 hours. It is estimated that 25 people will be interviewed for 1 hour each at 106 active Superfund sites each year for the purpose of revising the CIPs. Therefore, the to tal estimated annua l burden is 2,650 hours (Exhibit 9 ). EPA estimates that an average of 15 people will participate in a two - hour focus group 4 times a year at 5 active Superfund sites. The total estimated burden for all sites for each year is 600 hours. An average of 50 people is expected to participate in a three
- hour workshop session once a year at 10 active Superfund sites. The total estimated annual burden for all sites is 1,500 hours. EPA estimates that community groups will apply for available TA Gs at 10 Superfund sites. The application process is estimated to take approximately 60 hours. The total estimated annual burden for all sites is 600 hours. Management of TAGs takes place each year at an estimated 75 sites. This requires approximate ly 200 hours per year. The total estimated annual burden for all sites is 15,000 hours.

### 43 EPA expects to distribute satisfaction surveys at five (5) sites each year. It is estimated that 800 people will spend 0.25 hours (15 minutes) completing each survey . The total estimated annual burden hours at all sites is 1,000.

 **Superfund Site Evaluation and Hazard Ranking System** The costs incurred by State and Trib al respondents for conducting site assessment activities equals the estimated average cost per activity ( including laboratory costs) multiplied by the number of State/Tribal lead activities. In addition to activity
- specific costs, the States and Tribes incur infrastructure costs associated with developing and maintaining a State or Tribal site assessment pro gram. These infrastructure costs include such items as training, developing standard operating procedures, administrative support, and computers and automated data processing (ADP) support. The total estimated annual respondent cost is $ 11,238,970 , howev er b oth activity
- specific costs and infrastructure costs are reimbursed by the EPA , thus the effective respondent cost is $0. Exhibit 10 provides detailed information on the estimated annual respondent burden and costs as calculated based on projected FY 20 12 through FY 201 4 activity data. Depending upon how far a particular site progresses through the site assessment process, the respondent cost per site may range from $ 7,052 (average for conducting pre - CERCLIS screening and no other work) to $ 190,022 ( cumulative average for conducting pre
- CERCLIS screening, PA, SI, ESI and HRS package work).

 **Cooperative Agreem ents and Superfund State Contrac**  **ts for Superfund Response Action**  (i) Estimating Labor Costs For all activities covered by this ICR, wage rates for State, Tribal, and political subdivision personnel are estimated to be comparable to those of Federal government personnel. These wage rates were estimated based upon corresponding Federal GS wage rat es as of January 2012. The rates, as outlined below are m ultiplied by a 1.6 benefits multiplication factor to account for government overhead expenses.

Management GS 13, step 1 $54.94/hour Technical GS 11, step 1 $38.56/hour Cleri cal GS 7, step 1 $26.05/hour These rates are from the Office of Personnel Management (OPM) “2009 General Schedule” which excludes locality rates of pay. These rates can be obtained from the OPM website, http://www.opm.gov/oca/12tables/indexGS.asp . It is further estimated that approximately 20% of the respondent activity is Managerial, 70% is Technical, and 10% is Clerical in nature. Based upon the above, the weighted average is $40.59 per hour [(54.94*0.2)+(38.56*0.7)+(26.05*0.1)]. (ii) Estimating Capital and Operation and Maintenance Costs The only type of costs associated with this information collection activity is labor costs. There is no estimated Capital/Startup and Operation and Maintenance Costs associated with this collection of information. (iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs The total capital/startup costs for this ICR are $0. The total operation and maintenance (O&M) costs for this ICR are $0. The total respondent costs in block 14 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 costs to respondents over the next three years of the ICR is estimated to be $0.

### 46  **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** Respondent costs are divided into labor costs and other costs, which includes all operation and maintenance, non
- labor, and capital costs. The methodology for calculating these costs for the three year ICR period is addressed in detail below
. All costs the state incurs, with the exception of the ARARs analy sis, is ultimately paid for by the Federal government through any one of two relevant cooperative agreements (CAs) as stipulated in Subpart O of the NCP. These cooperative agreements are CORE agreements, which provide fund for infrastructure work and are non - site
specific in nature, and Remedial CAs that provide site
- specific money for remedial process actions in Superfund. (i) Estimating labor costs Labor rates for government employees are estimated using the Office of Personnel Management’s General Sche dule pay tables for 2011. For the purposes of this ICR, state government salaries are assumed to be the same as Federal pay scales. It is assumed that the average unit of remedial work is comprised of 10 percent managerial, 80 percent technical, and 10 p ercent support staff effort. Thus, a weighted average is used to represent the hourly labor rate of government work. To determine the hourly wage, 50 percent of the value of a Step 5, GS
- 12 ($32.73) and GS
- 13, ($38.72) are summed ($71.65) and then adjuste d for locality pay using a factor of 1.20, which results in $43.00. To further adjust for overhead, $43 is multiplied by 1.6, which results in $68.80, the governmental hourly labor rate applied to the following activities conducted by state agencies for the Superfund remedial program: Proposed Plans, RODs, ARARs, Administrative Records, initial CIPs, revised CIPs, fact sheets, focus groups, and workshops. The same hourly labor rate applies to all Federal activities. The hourly labor rate for the RI/FS ac tivity is calculated as 20 percent government and 80 percent contractor effort. These assessments involve a great deal of field work and typically involve lots of contractor support. Using past historical rates, the average contractor hourly labor rate i s estimated to be approximately 62 percent of the average government hourly labor rate. Therefore, the average contractor hourly labor rate is estimated to be $42.65. The average government hourly labor rate of $68.80 is used for the government’s 20 perc ent. Therefore, the average hourly labor rate for RI/FS work is $47.88, calculated by: [0.2(68.80) + 0.8 (42.65)]. The hourly labor rate for community members who participate in Superfund remedial activities on a voluntary, and non
-paid, basis is $19.20. The value is based on Bureau of Labor Statistics January 2010 data, which reports an average hourly wage of $18.80 for “production, non
- supervisory on private non farm payrolls, seasonally
adjusted” employees. The recent trend in this category of BLS data is for the rate to increase approximately $0.40 per year. Therefore, $19.20 is the average rate over the three
- year period of this ICR for all activities in which the community may participate. Labor costs for community activities represent hyp othetical costs only. (ii) Estimating capital, operations and maintenance, and other costs Capital, operation and maintenance (O&M), and non
- labor costs to states apply for the following Superfund remedial activities: RI/FS, Proposed Plans, RODs, Administrative Records, and fact sheets. The Federal government incurs none of these costs for oversight of state activities. The Federal government does incur non
labor costs for the Administrative Records, fact sheets, and satisfaction surveys. Commun ity members have no O&M, non
- labor or capital costs. States, communities, and the Federal government do not incur any capital costs in these Superfund remedial activities as no ne w equipment is purchased for their purposes. All O&M and non
- labor costs fo r RI/FS conducted at state
- lead sites are calculated from OSRTI contracts records from 1996
- 2006, adjusted for inflation, using a factor of 2.37, w hich is the average inflation rate in the United States from 2000
- 2010, based on the Bureau of Labor Statisti cs’ Consumer Price Index. The RI/FS contractor non - labor cost includes $84,301 in fees and profits, $121,301 for equipment, and $80,812 for indirect costs such as travel and reports. The equipment costs reflect charges for the use of equipment, such as c om puters

### 47

and sampling instruments, which the contractor already owns. The total non
- labor cost for each RI/FS in a single year is, therefore, estimated at $286,413 ( Exhibit 11 ). Operation and maintenance is defined as activities that are required to ke ep projects supported and moving forward. For the RI/FS it is estimated that contractors incur approximately $40,977 in a single year for each project. These costs include charges for mail, supplies, and faxes. O&M costs incurred by the Agency are discu ssed in the following paragraph. The bulk of O&M costs associated with Proposed Plans, RODs, Administrative Records, and fact sheets are those costs that are required for printing, document distribution, ne wspaper announcements, and records management. C osts for mailing and data collection with contractor support also apply to the satisfaction survey. Annual non
- labor costs for satisfaction surveys are estimated by EPA staff conducting the survey to be $6,142. For all other activities with O&M costs, th e values from the 2007 version of this ICR are used and adjusted for inflation. Inflation is calculated by using a percent of cost change value of 2.37. This value is estimated for the three
- year period of the ICR based on calculations from the Bureau of Labor Statistics’ Consumer Price Index. This number represents an average of the percent of cost change from three 3
- year periods (2002
- 2005; 2003
- 2006; 2007
- 2010). Using 2.37 as an inflation value, the following O&M annual costs for each activity are:

- Proposed Plan: $1,726

- RODs: $1,860

- Administrative Record: $1,398

- Fact Sheets: $1,676 (iii) Annualizing capital costs No significant capital costs are incurred during the activities described in this ICR.

6(c) Estimating Agency Burden and Costs

 **Superfund Site Evaluation and Hazard Ranking System** The EPA Regional offices review and manage sites assessed under Superfund by States and Tribes, and provide oversight for State and Tribal site assessment cooperative agreements. Based on average annual projections from FY 20 12 through FY 201 4 , the estimated average annual burden to the EPA for reviewing and managing site assessment activities conducted by States and Tribes under Superfund is 28,631 hours at an estimated cost of $1,969,813
. Reimbursement of state costs brings the total Agency cost to $ 13,208,782
. Exhibit 13 provides detailed information on the estimated annual Agency burden and costs as calculated based on projected FY 20 12 through FY 201 4 activity data. Based on the 20 1 1 GS pay schedule, EPA estimates an average hourly Regional labor cost of $ 43 , excluding the impact of benefits, to review and manage the work covered under this ICR. To derive hourly estimates, EPA divided annual compensation estimates by 2,080 which is the num

ber of hours in the Federal work year. EPA uses a multiplication factor of 1.6 to derive hourly estimates inclusive of benefits. Taking into account benefits, the average hourly rate is $ 68.80 ($ 43 x 1.6).

In addition to reviewing site assessment reports submitted by states and tribes, EPA staff conduct site management, oversight and quality assurance activities . Oversight activities include: reporting and recordkeeping activities such as establishing and maintaining a master database; answering respondent questions; auditing and reviewing data submissions; recording and entering data submissions; analyzing requests for confidentiality and pro viding confidentiality protection; reformatting and distributing data; and storing data.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  The only costs to the Agency are those costs associated with maintenance, analysis, and utilization of the collected information. The average Agency cost for the collection and administration of the information required by this ICR is estimated to be $2 58,993.80. This cost is based on the average hourly labor rate at a GS
- 12, Step 1, times a 1.6 benefits multiplication factor to account for government overhead expenses for a total hourly rate of $46.21. These rates are from the Office of Personnel Management (OPM) “2012 General Schedule” which excludes

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)**  Burden on the Environmental Protection Agency covered in the ICR includes those hours and costs incurred in overseeing state activities. For the RI/FS, Proposed Plans, ARARs, initial and revised CIPs, the assumption is that Federal oversight hours are 10 percent of the state’s burden hours for respective activities. For the Administrative Record, fact sheets, focus groups, and workshops the assumption is that Federal oversight hours are 5 percent of the state’s burden hours. These assumptions were p rovided by a group of Headquarters and Regional Community Involvement EPA employees with the experience to estimate the average Federal oversight hours for these activities. The total estimated annual burden hours placed on EPA for oversight of state acti vities is 14,713 ( Exhibit 15 ).

These activities include initial and revised CIPs, fact sheets, focus groups, workshops, satisfaction surveys, and TAGs. For these activities that are also conducted by states at state
- lead sites, the average hours required per activity is the same as the burden hours placed on the states. Total number of activities and the Federal hours required to complete them are estimated by a group of Headquarters and Regional Community Involvement EPA employees. EPA is also responsible for maintaining the Administrative Record at all active Federal
- lead sites at all stages of the cleanup process. It is estimated that these sites

### 53

comprise about 80 percent of all active sites. At the time of this writing there ar e approximately 530 active NPL sites (EPA database). Therefore, EPA is responsible for maintaining the AR at 424 sites. The total estimated annual burden hours placed on EPA for Community Involvement activities is 119,730 ( Exhibit 16 ).

To determine the hourly wage, 50 percent of the value of a Step 5, GS
- 12 ($32.73) and GS
- 13, ($38.72) are summed ($71.65) and then adjusted for locality pay using a factor of 1.20, which results in $43. To further adjust for overhead, $43 is multiplied by 1.6, w hich results in $68.80. The annual labor cost for each activity that involves use of Federal hours i s calculated using this labor rate. Labor costs to EPA are the only Federal costs accounted for oversight of state activities. The total estimated annual costs incurred by EPA for oversight of state activities is $1,012, 402 ( Exhibit 17 ). The total estimated annual costs EPA incurs for Community Involvement activities is $11,846,976 ( Exhibit 18 ). Exhibit 17

**National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** (i) Respondent tally The total burden hours and costs displayed in the table below reflects the combined burden and costs on both categories of respondents: states at state - lead sites and individual community members participating voluntarily at Superfund sites. Community costs of $552,000 (Exhibit 20) are all hypothetical and do not represent the actual expenditure of dollars because all participation is voluntary. The majority of state costs may be paid through various grants from the Federal government. The actual cost to states is $261,440 (Exhibit 20) for the ARAR analysis.

Additional, activities that depend almost exclusively on the need at the site, such as fact sheet, are likely to vary year to year. However, EPA expects the relative number of annual activities to be similar in each year of the ICR period. 6(d) Estimating the Respondent Universe and Total Burden and Costs

 **Superfund Site Evaluation and Hazard Ranking System** EPA estimates that an annual average of 60 States (including U.S. Territories) and Tribes will perform the site assessment activities described in this ICR. The estimated annual burden to these respondents for performing these activities is approximately 1 21,681 hours at a cost of approximately $ 11, 238,970 . One hundred percent of the respondent cost ($ 11, 238,970 ) is reimbursed by the EPA through cooperative agreements. On average, EPA estimates each respondent will complete and submit approximately 9 to 10 assessment reports per year.

### 57  **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  Based on our research for this ICR, approximately 674 respondents will provide the information required under 40 CFR Part 35, Subpart O each year. The number of Total Annual Responses is 674. The total annual labor costs are $220,221.59. Details regarding these es timates may be found in Exhibit 7 (Total Respondent Burden of Cooperative Agreements and Superfund State Contracts for Superfund). Note that the total annual capital and O&M costs to the regulated entity are $0. These costs are detailed in Section 6(b)(iii), Capital/Startup vs. Operation and Maintenance (O&M) Costs. The total annual burden is 7,162 hours.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** The respondent universe is based on the number of state
- lead and active Superfund sites predicted for the three
- year period of the ICR. These numbers come from Superfund data about past activities and scheduled plans for future activities. The number of community members involved at each site clearly varies and this respondent universe is based on past program averages. The total burden and cost to each respondent is a summation of all activities described in detail in previous sections of this document. 6(e) Bottom Line Burden Hours and Costs Consolidated ICRs Respondent Burden:

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  The increase in burden from the most recently approved ICR of $91,754.92 and 2,973 hours reflects an increase in the estimated number of respondents from the previous ICR. The estimate of respondents is expected to increase by 106. Overall estimated burden has increased for both the respondents and the agency. The agencies increase was du e to increased detail needed for post award monitoring and a 1.5 hour increase was applied across all CAs. The respondents increase was due in part to requirements to link work plans to environmental results, provide more detail regarding how

work plans ar e progressing, include more specific accomplishments regarding work plans, increased reporting requirements for quarterly reports and final performance requirements, more complicated negotiations, and for post award monitoring . M ore questions have been add ed and states are asked to provide mo re information.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** There is no change in burden.

 **Consolidation** As a result of the consolidation of three ICR’s into one, the burden for ICR 1487, OMB # 2050
- 0179, Cooperative Agreements and Superfund Contracts for Superfund Response Actions is being increased. The ICR’s being added to this one are ICR 1488, OMB # 2050
- 0095 Superfund Site Evaluation and Hazard Ranking System , and ICR 1463, OMB # 2050
- 0096 National Oil and Hazardous Substances Pollution Contingency Plan (NCP)
. The consolidation will help to streamline the program’s information collection efforts. 6( g ) Burden Statement  **Superfund Site Evaluation and Hazard Ranking System** Depending on the number and type of activities performed, average burden per Response is estimated as 2 13.85 hours. Burden ranges from 8 9 to 2, 450 hours p er site. The number of hours required to assess a particular site depends on how far a site progresses through the site assessment process. Sites where only a pre
- CERCLIS screening is performed will on average require approximately 8 9 hours (average for conducting pre
- CERCLIS screening and no other work), wh ile sites that progress to NPL listing may require approximately 2, 450 hours

### 59

(cumulative average for conducting pre
- CERCLIS screening, PA, SI, ESI and HRS package work). This burden estimate includes reporting activities and minimal recordkeeping activities.

 **Cooperative Agreem ents and Superfund State Contracts for Superfund Response Actions**  The annual public reporting and recordkeeping burden for this collection of information is estimated to average 11 hours per response.

 **National Oil and Hazardous Substances Pollution Contingency Plan (NCP)** The total estimated annual burden hours placed on state governments for all remedial activities is 154,465. The total estimated annual burden hours placed on communities is 25, 150 . Total burden hours placed on 11,659 respondents through 12,977 responses is 179,615 hours. The annual public reporting and recordkeeping burden for this collection of information is estimated to average 13.84 hours per response. The ICR covers an array of activities that may occur at various discrete points in time or periodically throughout the entire Superfund remedi al process. Therefore, the number of likely respondents per Superfund site in both the state and community categories will vary by site depending on its position in the remedial process, the lead agency, and the level of community involvement warranted. Additionally, the frequency of response to all activities covered by the ICR can only be described as occurring when required to meet CERCLA requirements and the needs of the Superfund site and the community. Burden means the total time, effort, or fin ancial 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 personne l 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 respo nd 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 Number EPA
