Statement Supporting the Revisions to the Tier I and Tier II Emergency and Hazardous Chemical 

Inventory Forms (Final Rule) for Community Right-to-Know Reporting Requirements of the 

Emergency Planning and Community Right-to-Know Act

1. IDENTIFICATION OF THE INFORMATION COLLECTION

1(a) Title of the Information Collection Request

Hazardous Chemical Reporting: Revisions to the Emergency and Hazardous Chemical Inventory 

Forms (Tier I and Tier II) (Final Rule). EPA No. 2436.02, OMB No. 2050-0072.

1(b) Short Characterization

This information collection request (ICR) estimates the burden and costs associated with adding 

some new data elements to the Hazardous Chemical Inventory forms, Tier I and Tier II, under section 312 

of EPCRA. 

Sections 311 and 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA)

apply to the owner or operator of any facility that is required to prepare or have available a Material 

Safety Data Sheet (MSDS) for a hazardous chemical under the Occupational Safety and Health Act of 

1970 and its implementing regulations. Under section 311 of EPCRA, these facilities are required to

submit an MSDS to the State Emergency Response Commission (SERC), the Local Emergency Planning 

Committee (LEPC), and the local fire department for each hazardous chemical stored on-site in a quantity 

greater than the reporting threshold. Alternatively, a list of subject chemicals, grouped by hazard type, 

may be submitted. The reporting threshold is 10,000 pounds unless the chemical is specifically listed as 

an Extremely Hazardous Substance (EHS) under EPCRA section 302, in which case the reporting 

threshold becomes 500 pounds or the Threshold Planning Quantity (TPQ), whichever is less. The 

reporting threshold for gasoline (all grades combined) is 75,000 gallons and for diesel fuel (all grades 

combined) is 100,000 gallons, when stored entirely underground at retail gas stations that are in 

compliance with Underground Storage Tanks (UST) regulations. 

Section 312 of EPCRA requires owners and operators of facilities subject to section 311 to 

annually report the inventories of those chemicals reported under section 311. The Environmental 

Protection Agency (EPA) is required to publish two emergency and hazardous chemical inventory forms, 

known as “Tier I” and “Tier II,” for use by these facilities. These forms were published in October 1987 

and amended in July 1990. On August 8, 2011 (76 FR 48093), EPA proposed some additional data 

elements to the Tier I and II forms and proposed to revise some existing data elements to the Tier II form.

EPA is now finalizing most of the data elements proposed. EPA is also adding some optional data 

elements.

The Tier I form provides the minimum amount of information necessary to comply with section

312. Any facility that is required to submit an MSDS or list of chemicals under section 311 must submit a 

Tier I form annually on March 1, incorporating the chemicals reported under section 311. Tier I form is

submitted to the SERC, LEPC, and local fire department. The Tier II form, which provides chemicalspecific information, is submitted in lieu of the Tier I form only if specifically requested by the SERC or 

LEPC.

States were always given the flexibility to implement EPCRA as appropriate for their State to 

meet the goals of EPCRA, which is to prepare for and respond to releases of EHSs and to provide the 

public with information on potential chemical risks in their communities. This flexibility includes adding 

more chemicals, setting lower reporting thresholds and creating a reporting form or format that includes 

more information than the federal reporting requirements. Many States have more stringent requirements, 

such as additional chemicals and lower reporting thresholds. Some States developed their own inventory 

reporting form, including electronic reporting format and certification. Other States use the federal 

inventory reporting form or the federal electronic reporting format, Tier2 Submit. 

The data elements that EPA is finalizing are for the federal emergency and hazardous chemical 

inventory reporting forms, Tier I and Tier II. EPA is also revising some existing data elements in the 

chemical reporting section of the Tier II form to ease reporting for facilities and make the forms more 

user-friendly for state and local agencies. The data elements that EPA is adding to the forms are 

requested by state and local agencies for improving their emergency response plans and for coordinating 

response during an emergency. 

EPA estimates that approximately 390,000 manufacturing and non-manufacturing facilities are 

currently subject to reporting and recordkeeping requirements under EPCRA sections 311 and 312. EPA 

believes that this final rule would impose only minimal burden since the data elements that EPA is 

finalizing are readily available to facilities. The data elements are related to the general facility 

identification and contact information for the parent company, owner or operator of the company, facility 

emergency coordinator etc. These data elements usually would not change from year to year. The data 

elements that we are revising in the chemical reporting section of Tier II form would ease reporting for 

facilities and make forms more user-friendly. The total one-time burden for facilities to report the data 

elements is estimated to be 97,500 hours at a cost of $5,152,125. Since the new data elements added are 

useful for planning and emergency response, it is important that facilities review the information reported 

annually and make revisions. Therefore EPA assumes the same burden annually. 

During the first year that the rule becomes effective, facilities would need to get familiarize with 

the new changes to the Tier II inventory form and also to gather information for reporting the new data 

elements. EPA estimates a total one-time burden for manufactures and non-manufacturers for this 

activity to be 292,500 hours at a cost of $15,456,375. 

There are estimated to be 3,552 SERCs and LEPCs. As of 2010 reporting year, there are only 20 

states that have developed their own reporting format. EPA estimates that each of these states would 

spend approximately 200 hours at a cost of $50,000, initially in the first year when the rule becomes 

effective to modify their electronic reporting software to add and revise existing data elements. The cost 

associated with adding new data elements is estimated to be $1,000,000.

2. NEED FOR AND USE OF THE COLLECTION

2(a) Need/Authority for the Collection

The authority for these requirements is EPCRA section 312 (42 U.S.C. §11022).

Section 312 requires the same owners or operators of facilities subject to section 311 to annually 

report the inventories of the chemicals reported under section 311. Section 312(g) requires EPA to 
Page 3 of 12

publish emergency and hazardous chemical inventory forms for use by facilities subject to this section. In 

final rules published in the Federal Register on October 15, 1987, and amended on July 26, 1990, EPA 

published the two “formats” required under EPCRA, “Tier I” and “Tier II.” Tier I is the minimum 

amount of information necessary to comply with the section. Using Tier I, facilities aggregate reportable 

chemicals by hazard type and provide the quantities and locations of the chemicals. The Tier II Form is 

chemical-specific information and only needs to be submitted (in lieu of the Tier I Form) if specifically 

requested by the SERC or LEPC.

EPA is adding some new data elements to the Tier I and Tier II forms and revising some existing 

data elements in the chemical reporting section of the Tier II form.

2(b) Practical Utility/Users of the Data

The reports required under sections 311 and 312 are submitted to the state and local officials 

which will be then accessible to the public. The public will have knowledge of the hazards in their 

community. State and local officials use the information submitted to them for developing and modifying 

emergency response plans for their community. 

3. NON-DUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA

3(a) Non-Duplication

Many states have laws that require information similar to that called for by sections 311 and 312 

of EPCRA. EPA allows the state program to suffice for reporting provided that the minimum reporting 

requirements are met. The burden estimate in this ICR also includes burden imposed on facilities that 

comply with State requirements. 

3(b) Public Notice 

Prior submitting an ICR to OMB, EPA is required to publish a Federal Register notice soliciting 

comments on the burden and cost estimates that EPA developed for the proposed rule. The notice was 

published on August 8, 2011 (76 FR 48093).

3(c) Consultations

EPA received comments from few members of the regulated community on the estimates for the 

number of hours for reporting new data elements on the Tier II form. The commenter stated that EPA 

underestimated the burden that it would only take 15 minutes to comply with the new data elements that 

EPA proposed. EPA realizes that the regulated community would also need to get familiar with the new 

data elements and other changes made to the Tier II form. Therefore, EPA is revising the estimates for 

the number of hours that this final action would impose on the regulated community. See Section 6 of 

this document.

3(d) Effects of Less Frequent Collection

The reporting deadlines for sections 311 and 312 are set by statute. EPA has no authority to allow 

less frequent collection.
Page 4 of 12

3(e) General Guidelines

The collection activities specified in this ICR adhere to the guidelines specified by OMB.

3(f) Confidentiality

The respondent may claim specific chemical identities as trade secret in reports submitted under 

Section 312 and in the list of chemicals and material safety data sheets submitted under Section 311. 

Such information must be submitted according to EPCRA sections 322 and 323 (40 CFR Part 350).

All trade secrecy claims submitted to EPA under EPCRA are handled and stored according to 

procedures set out in the Manual for Physical Handling, Security, and Protection of Files containing 

Trade Secret Claims Submitted under Sections 303, 311, and 312 of the Emergency Planning and 

Community Right-to-Know Act (EPCRA), March 2010. These procedures were developed for EPCRA

trade secrecy claims with the knowledge that these documents are sensitive. Handling and review of 

documents containing EPCRA trade secret information is permitted only by persons who have obtained 

formal clearance to access the information based on a work-related need to engage in these activities. 

When not being processed or reviewed by authorized individuals, the claim submissions containing trade 

secret information are stored in restricted access areas. To ensure that appropriate handling procedures 

are activated and the confidentiality of EPCRA trade secret submissions is maintained, the Agency 

attaches a cover sheet to the top of each trade secret document and otherwise marks the document to 

clearly identify the document as “confidential”.

3(g) Sensitive Questions

The information gathering activities under this renewal ICR do not involve any sensitive 

questions.

4. THE RESPONDENTS AND THE INFORMATION REQUESTED

4(a) Respondents

Section 312 is applicable to all facilities that are required to prepare or have available an MSDS 

for a hazardous chemical as required under OSHA and its implementing regulations. Section 1910.1200 

of the OSHA regulations provides exemptions from the definition of hazardous chemical. 

In addition, Section 311(e) of EPCRA excludes the following substances:

• Any food, food additive, color additive, drug, or cosmetic regulated by the Food and Drug 

Administration;

• Any substance present as a solid in any manufactured item to the extent exposure to the 

substance does not occur under normal conditions of use;
Page 5 of 12

• Any substance to the extent it is used for personal, family, or household purposes, or is 

present in the same form and concentration as a product packaged for distribution and use 

by the general public;

• Any substance to the extent it is used in a research laboratory, hospital, or other medical 

facility under the direct supervision of a technically qualified individual; and

• Any substance to the extent it is used in routine agricultural operations or is a fertilizer 

held for sale by a retailer to the ultimate customer.

Also, reporting thresholds have been established under sections 311 and 312 (codified in 40 CFR 

part 370). A facility must report those hazardous chemicals that are present at the facility at any time at or 

above the following levels:

• For EHSs, 500 pounds or the threshold planning quantity (TPQ), whichever is less.

• For hazardous chemicals other than EHSs, the reporting threshold is 10,000 pounds.

• For gasoline, 75,000 gallons (all grades combined) and 100,000 gallons for diesel fuel (all 

grades combined), when stored entirely underground at retail gas stations that are in 

compliance with UST regulations.

4(b) Information Requested

4(b)(i) Data Items

On or before March 1 of each year, facilities having hazardous chemicals that need reporting must 

submit a Tier I Form. However, the Tier II Form must be submitted upon request by the SERC, LEPC or 

the fire department with jurisdiction over the facility Currently all states require facilities to submit the 

federal Tier II inventory form or the state developed inventory reporting form or electronic reporting 

format. Some states require facilities to use Tier2 Submit, the electronic software developed by EPA. 

The Tier I Form includes the following information as required by the statute:

 An estimate in ranges of the maximum amount of hazardous chemicals in each hazardous 

category present at the facility at any time during the previous year; 

 An estimate in ranges of the average daily amount of hazardous chemicals on-site in each 

hazard category present at the facility during the preceding calendar year; and

 The general location of hazardous chemicals in each category.

EPA has added the following information on the Tier I form in the final rules published on October 15, 

1987 (52 FR 38344), July 26, 1990 (55 FR 30632) and November 3, 2008 (73 FR 65452).

 NAICS code and Dun and Bradstreet number of the facility
Page 6 of 12

 Emergency contact (added to give SERCs, LEPCs, and local fire departments a contact at 

the facility who could clarify information at any time, particularly in the event of an 

emergency); and

 Number of days on-site (added to produce a more accurate estimate of the average daily 

amount, particularly for those chemicals that are on-site for only a short period of time 

each year).

The Tier II Form includes the following information as required by statute:

 The chemical name or the common name of the chemical as provided on the material 

safety data sheet;

 An estimate (in ranges) of the maximum amount of the hazardous chemical present at the 

facility at any time during the preceding calendar year;

 An estimate (in ranges) of the average daily amount of hazardous chemical present at the 

facility during the preceding calendar year;

 A brief description of the manner of storage of the hazardous chemical; and

 The location of the hazardous chemical within the facility.

The following data elements were added to the Tier II form in the final rules published on October 15, 

1987, July 26, 1990 and November 3, 2008.

 CAS number to identify more accurately each chemical that is reported; 

 The physical state to help identify the type of hazard a chemical represents in an 

emergency;

 The physical and health hazards associated with the chemical;

 Primary NAICS code and Dun and Bradstreet number of the facility

 Two emergency contacts (added to give SERCs, LEPCs, and local fire departments a 

contact at the facility who could clarify information at any time, particularly in the event of 

an emergency); and

 Number of days on-site (added to produce a more accurate estimate of the average daily 

amount, particularly for those chemicals that are on-site for only a short period of time 

each year).

On August 8, 2011 (76 FR 48093), EPA proposed to add some new data elements to Tier I and 

Tier II forms and revise some existing data elements in the chemical reporting section of the Tier II form. 
Page 7 of 12

EPA is now finalizing the following as mandatory data elements to both Tier I and Tier II forms. 

Although Tier I inventory form is no longer used by any state, the statute requires EPA to publish both 

forms so changes are also finalized on the Tier I inventory form.

 Latitude and Longitude of the facility;

 Maximum Number of Occupants; 

 An indication whether the location of the facility is manned or unmanned; 

 Facility identification numbers assigned under the Toxic Chemical Release Inventory and 

the Risk Management Programs;

 Email address for the owner or operator of the company;

 Name, title, email address, phone number and 24-hour phone number of the facility 

emergency coordinator;

 Name, title, email address, phone number of the person knowledgeable of the information 

reported on the Tier I and Tier II forms; 

 Email address of the emergency contact(s);

 To indicate whether the facility is subject to EPCRA section 302; and 

 To indicate whether the facility is subject to Clean Air Act (CAA) section 112 (r), also 

known as the Risk Management Program.

The following data elements are added to the forms as optional.

 Name, address, phone number, Dun & Bradstreet number and email address of the parent 

company; and

 Phone number of the facility.

Since the statute specifically states that an estimate in ranges for the maximum amount and 

average daily amount should be reported on the Tier I and Tier II inventory forms, the regulations may 

only require reporting of these amounts in ranges. The range codes currently listed in the regulations are 

very broad. However, in order for the States, local agencies and emergency response officials to have 

information on the maximum amount and average daily amount that are closer to the actual amounts 

present at the facility, EPA proposed to narrow the ranges in August 2011 and we are now finalizing the 

reporting ranges.

EPA also proposed to revise some existing data elements under the chemical reporting section of 

the Tier II inventory form. Prior to the proposal, the form only included one entry to report pure chemical 

and mixtures. EPA proposed two separate entries, one for pure chemical and one for mixture, which will 
Page 8 of 12

make reporting easier for facilities and make the form more user friendly for states and local agencies. 

EPA is now finalizing two separate entries for reporting pure chemical and mixtures. As stated in section 

370.14 of the regulations, facilities have the option to report the components or the total mixture. 

However, EPA encourages facilities to report consistently under sections 311 and 312 for mixtures. 

EPA also proposed facilities to provide a description for storage types and conditions on the Tier 

II form for the hazardous chemicals that are reported. Prior to the proposal, facilities were asked to report 

a code to represent the storage types (i.e. steel drum, underground storage tank, etc.) and storage 

conditions (i.e. ambient temperature, ambient pressure, etc). These codes were provided in section 370.43 

of the regulations. 

State and local agencies requested EPA to delete the codes and require facilities to provide a 

description so these agencies would have information readily available during an emergency rather than 

searching through the instructions of the form to see what each code represent. 

In the final rule, EPA is requiring facilities to provide a description for storage types and 

conditions as proposed. 

4(b)(ii)Respondent Activities

To determine if the facility is subject to section 311, a facility must look at inventory records for 

all of its chemicals that are required to have MSDSs. The facility would also have to review the EHS list 

to determine if any of the chemicals are subject to a lower reporting threshold.

If the facility determines that it has hazardous chemicals that must be reported, it must determine 

the address of the SERC, LEPC, and local fire department. Copies of the MSDSs for these chemicals 

may be submitted, or if preferred, the facility may provide a list of the subject chemicals grouped by 

hazard type. To use the list option, the facility would have to read the MSDS to determine into which of 

the five hazard types the chemical falls and to identify it on the list.

The same chemicals that a facility would need to report under section 311 would need to be 

reported under section 312. To complete the Tier I form, the facility would need to monitor its inventory 

records for the chemical (to determine the inventory information), add the quantities together for 

chemicals having the same hazards, and determine the correct code for the total quantity.

A site map may be easier to show locations of hazardous chemicals, or the facility may choose to 

provide the general location.

As mentioned in the previous section of this document, all states now require facilities to submit 

the federal Tier II inventory form or the state developed inventory reporting format, including electronic 

submission. 

5. THE INFORMATION COLLECTED: AGENCY ACTIVITIES, COLLECTION 

METHODOLOGY, AND INFORMATION MANAGEMENT

5(a) Agency Activities
Page 9 of 12

No information provided under sections 311 and 312 is sent to EPA. All of the information is 

collected and kept at the state and local agencies. 

EPA developed the electronic reporting format, Tier2 Submit and is modified annually. EPA also 

input State required data fields in the Tier2 Submit requested by the State. Approximately 10 states 

request EPA to input new data fields annually. The Agency would be revising the Tier2 Submit to 

include the new data elements finalized in this action. 

5(b) Collection Methodology and Management

EPA does not receive the data; therefore, EPA does not have any special data collection 

methodology and management. EPA created computer software for use by facilities to submit Tier II 

reports, Tier2 Submit. Approximately 20 states use Tier2 Submit. Other states have created their own 

software using their own resources and require facilities to submit electronically (online or diskette). Few 

states still accept paper submission.

5(c) Small Entity Flexibility

The burden hours for small businesses are considered to be smaller than those for large facilities 

because of the reduced number of chemicals present at smaller facilities. However, for the new data 

elements added to the Tier II form, EPA is considering the same burden for small and large facilities.

5(d) Collection Schedule

The frequency of collection for these sections of EPCRA is required by the statute. The facilities 

subject to Section 312 is required to submit either Tier I or Tier II (upon request) by March 1 annually. 

As stated earlier in this document, all states now require facilities to submit Tier II or the state equivalent 

inventory form or format. 

6. ESTIMATING THE BURDEN AND COST OF THE COLLECTION

6(a) Estimating Respondent Burden

EPA estimates that approximately 390,000 facilities may be subject to section 312 reporting 

requirements, therefore, subject to reporting the new data elements finalized to the Tier II form. EPA 

estimates that out of 390,000 facilities, there are 120,000 manufacturers and 270,000 non-manufacturers. 

As mentioned earlier in the document, EPA estimates the same unit burden for small, medium and large 

facilities since the time required to report the new data elements that EPA is finalizing will be the same 

for all facilities. 

All states now require facilities to submit the federal Tier II form or the state developed reporting 

form or format. Therefore this ICR only accounts the burden imposed for reporting the Tier II or the state 

developed reporting form or format. The new data elements that the Agency is finalizing are readily 

available to facilities. EPA estimates that it takes approximately 15 minutes (0.25 hours) for a technical 

staff at each facility to record new data elements on the Tier II form. During the first year that the rule 

becomes effective, EPA estimates that it would take a technical staff approximately 45 minutes (0.75 
Page 10 of 12

hours) to get familiarize with the rule and gather information for the new data elements that EPA is 

finalizing in this action. In subsequent years, EPA assumes that it would only take facilities 0.25 hours to 

review the new data elements and revise if necessary. 

Total burden for manufacturers to report the new data elements on the Tier II form is 30,000

hours. Total burden for non-manufacturers to report the new data elements on the Tier II form is 67,500 

hours. 

During the first year of the effective date of the rule, EPA estimates a total burden of 90,000 hours 

for manufacturers to get familiarize with the new requirements, For non-manufacturers, the total burden 

to get familiarize with the rule is estimated to be 202,500 hours. EPA do not expect this burden beyond 

the first year of the effective date of the rule. 

The new data elements that EPA is finalizing may not change yearly for any facilities. 

Approximately 40 states require facilities to submit their inventory form electronically. For these 

facilities, any changes that may occur for any of the new data elements can be revised with little or no 

burden. Therefore the burden associated with this ICR for reporting new data elements is not expected to 

incur after the initial reporting. However, since the information is vital for planning and emergency 

response, EPA assumes a total of 97,500 hours for manufacturers and non-manufacturers. 

The existing data elements that EPA is revising in the chemical reporting section of the Tier II 

form would ease reporting for facilities and make the form more user-friendly for state and local agencies. 

As of reporting year 2010, approximately 20 states have their own electronic reporting tool for 

submitting hazardous chemical inventory. Based on the federal cost and hours to make changes to the 

Tier2 Submit, EPA estimates that each state would spend approximately 200 hours to add new data 

elements and revise existing data elements to their existing software at a cost of $50,000. The costs

include initial analysis, design, programming, alpha and beta testing, and field deployment. 

Data management burden for State and local agencies is not estimated in this ICR since the new 

data elements will be part of the inventory form that these entities receive annually. 

6(b) Estimating Respondent Costs

The annual costs to manufacturers were estimated by multiplying the respondent burden estimate

for manufacturing facilities by the labor rate for the technical staff for reporting the information for the 

new data elements that EPA is proposing. The annual costs to non-manufacturers were estimated by 

multiplying the respondent burden estimate for non-manufacturing facilities by the labor rate for the 

technical staff responsible for recording the information for the new data elements that EPA is proposing.

EPA estimates an hourly respondent labor cost for a technical staff at a manufacturing facility is 

$61.24, including wages and benefits. Hourly respondent labor cost for a technical staff at a nonmanufacturing facility is estimated at $49.11. (Source: Bureau of Labor and Statistics, December 2011.

Capital and O&M Costs

There are no capital or O&M costs associated with this proposed rule. States will be using their 

existing computer software to add the new data elements or revise the existing data elements. 
Page 11 of 12

Estimating Agency Burden and Cost

EPA estimates that it will cost the Agency approximately $50,000 to make changes to the 

electronic reporting software, Tier2 Submit, for adding new data elements and revising the existing data 

elements. 

6(d) Estimating Total Annual Respondent Burden

Although EPA believes that the new data elements added to the Tier II form may not change

annually, EPA estimates that the total respondent burden for 390,000 facilities (120,000 manufacturers 

and 270,000 non-manufacturers) is 97,500 hours, at a cost of $5,152,125. The data elements that EPA is 

proposing are expected to be the same year after year. However, it is important for facilities to review 

and update the data elements that EPA is finalizing in this action since the information reported would be 

used for effective emergency planning and response. 

In addition, during the first year of the effective date of this final action, EPA assumes that 

facilities would need to get familiarize with the new changes to the Tier II form and also to gather 

information for reporting the new data elements. EPA estimates a total one-time burden for manufactures 

and non-manufacturers for this activity to be 292,500 hours at a cost of $15,456,375. 

Atleast 20 states would have to make changes to their reporting software for the changes discussed 

in the proposed rule. For these states, EPA estimates that it may cost $50,000 for each state, for a total 

cost of $1,000,000. Approximately 23 states use Tier2 Submit and these states are not expected to incur 

any burden since EPA is modifying the system and making it available to states. 

6(e) Bottom Line Burden Hours and Cost

The total one-time burden to facility respondents for rule familiarization is 292,500 hours at a cost 

of $15,456,375. The Annual burden for reporting new data elements and making any necessary revisions 

in subsequent years is estimated to be 97,500 hours at a cost of $5,152,125. 

The total one-time burden for 20 states that need to modify their reporting software is 4,000 hours 

at a cost of $1,000,000.

6(f) Burden Statement 

For this final rule, the average burden for facilities to get familiarize with the new requirements is 

0.75 hours. The average burden for reporting new data elements is estimated 0.25 hours for facilities.

The average burden for each state to add new data elements and revise existing data elements in 

their electronic software is 200 hours. Most of the states may already require these data elements that 

EPA is finalizing. Only a percentage may need to revise their regulations or software to require the new 

data elements that EPA is finalizing. 

Burden means the total time, effort, or financial resources expended by persons to generate, 

maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time 
Page 12 of 12

needed to review instructions; develop, acquire, install, and utilize technology and systems for the 

purposes of collecting, validating, and verifying information, processing and maintaining information, and 

disclosing and providing information; adjust the existing ways to comply with any previously applicable 

instructions and requirements; train personnel to be able to respond to a collection of information; search 

data sources; complete and review the collection of information; and transmit or otherwise disclose the 

information. An agency may not conduct or sponsor such a request and a person or facility is not required 

to respond to a collection of information unless it displays a currently valid OMB control number. The 

OMB control numbers for EPA’s regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15.

To comment on the Agency's need for this information, the accuracy of the provided burden 

estimates, and any suggested methods for minimizing respondent burden, EPA has established a public 

docket for the proposed rule, which includes this ICR, under Docket ID number EPA-HQ-SFUND-2010-

0763, which is available for online viewing at www.regulations.gov, or in person viewing at the
