The 2015 Supporting Statement for OMB 0596-0182
Qualified Product List for Wildland Fire Chemicals
A. Justification
Explain the circumstances that make the collection of information necessary. Identify any legal or administrative requirements that necessitate the collection. Attach a copy of the appropriate section of each statute and regulation mandating or authorizing the collection of information.
Laws, Statutes, and Regulations
Forest Service Manual (FSM) 5162 – Fire Management Equipment and Supplies
The policy of the Forest Service is stated in Forest Service Manual (FSM 5162.03), “Use only evaluated, approved and qualified fire chemicals.” This policy requires the Agency to evaluate all wildland fire chemicals before use in fire management activities on lands managed by the FS. Additionally, the Agency needs “to have available and utilize adequate types and quantities of qualified fire chemical products to accomplish fire management activities safely, efficiently, and effectively.” To accomplish this objective, the Forest Service evaluates fire chemical products available for use in direct wildland-fire management operations prior to such use on lands managed by the Agency. (FSM 5162.02, 5162.03).
Safe products do not contain ingredients that create an increased risk to firefighters or the public in typical use. The decisions regarding product effects are based on acute toxicity determinations of the products, a review of lists of known and suspected carcinogens, and risk assessments conducted on each product. The safety of firefighters’ equipment, either ground-based or aircraft, is also considered (i.e., uniform and intergranular corrosion tests, effects on non-metallic materials, etc.).
Safety to the environment in terms of aquatic (fish, clean water) and terrestrial environments (wildlife, plants) is also considered. Acute toxicity tests identify potential acute toxicity concerns. Risk-determinations assist in identifying products that with typical use do not increase danger to the environment.
Effectiveness tests for long-term fire retardants measure a product’s ability to reduce fire spread and intensity even after the water has evaporated.
Effectiveness tests for Class A foams include determining the relationships between the amount of the foam concentrate in water and the resulting wetting and foaming ability and the stability of the resulting foam.
Effectiveness tests for water enhancers (gels) include determining the relationships between the amount of the concentrate in water and the resulting viscosity and cohesiveness and the stability of these characteristics.
The product concentrate and mixtures of product concentrate in water are assessed to determine whether the product can be stored, mixed, and used with readily existing facilities and equipment as typical in wildland fire operations.
Finally, evaluation and qualification of products is based upon meeting the standards identified in the appropriate fire chemical specification.
Indicate how, by whom, and for what purpose the information is to be used. Except for a new collection, indicate the actual use the agency has made of the information received from the current collection.
What information will be collected - reported or recorded? (If there are pieces of information that are especially burdensome in the collection, a specific explanation should be provided.)
Each item of information is collected one time only, from the submitter, when a request to test a new product is made. The following information is collected:
The Manufacturer’s Safety Data Sheet (MSDS)
For the product(s) submitted for testing shall be provided by the individual or company submitting a product(s) for evaluation

What will this information be used for - provide ALL uses?
The information provided will allow the Forest Service to search and determine if any of the ingredients are on the:
List of unacceptable ingredients as defined in US Forest Service Specification 5100-304c, 5100-306a, or 5100-307a, section 2.2 and amendments
List of Known and Suspected Carcinogens, or
The U.S. Environmental Protection Agency’s List of Extremely Hazardous Materials
If an ingredient does occur in sufficient quantity for concern, it will trigger a risk assessment, prior to accepting the product for evaluation, to determine risk to Forest Service employees evaluating the product. A risk assessment will be performed on every product prior to addition to the Qualified Products List determine risks to human/environmental health by typical use of the product.
Cost of performing a risk analysis is the submitter’s responsibility and will be included in the cost of the evaluation.
How will the information be collected (e.g., forms, non-forms, electronically, face-to-face, over the phone, over the Internet)? Does the respondent have multiple options for providing the information? If so, what are they?
Forms FS-5100-32, FS-5100-33, FS-5100-34, FS-5100-35, FS-5100-36, FS-5100-37, FS-5100-38, and FS-5100-39 are all available in electronic form on the WFCS website or via e-mail from the Forest Service - WFCS, as the respondent prefers. All forms may be completed electronically or by typewriter. Material Safety Data Sheets are typically available electronically. Responses should be collected and submitted as a single package by e-mail, USPS, or by other standard business methods.
How frequently will the information be collected?
Information is collected for each formulation or reformulation once, following the respondent’s initial request for evaluation. Historically, an average of five respondents will submit ten new responses during a twelve-month period.
Will the information be shared with any other organizations inside or outside USDA or the government?
Proprietary information submitted to the Forest Service is kept in a secure location and subject to non-disclosure agreements between WFCS and other entities prior to sharing and discussion, as necessary, with the risk assessment preparer and representatives of US Fish and Wildlife Service and NOAA-Fisheries as part of Forest Service consultation with these agencies as required by the National Environmental Protection Act, Endangered Species Act, and the Notice of Decision under the Environmental Impact Statement on the use of Long-Term Retardant. Once a product successfully completes the evaluation and is added to the Qualified Products List (QPL) basic information on product mixing, characteristics and performance will be provided via the WFCS website which is available to potential users such as the Department of the Interior’s wildland fire agencies, state wildland fire agencies, and international wildland fire cooperators (i.e., Canada and Australia).
If this is an ongoing collection, how have the collection requirements changed over time?
The basic collection of specific information has not changed.
As the product specifications have evolved, the Forest Service has reduced the amount of information collected. The Agency has identified the information necessary to evaluate the products and determine potential hazards to people or the environment. In the case of potentially hazardous residual content created in development of an ingredient, the Agency asks for additional information necessary to address the potential risk to either the environment or human health.
Describe whether, and to what extent, the collection of information involves the use of automated, electronic, mechanical, or other technological collection techniques or other forms of information technology, e.g. permitting electronic submission of responses, and the basis for the decision for adopting this means of collection. Also, describe any consideration of using information technology to reduce burden.
The Forest Service forms used to collect information from respondents are available electronically. The Agency accepts electronic and hard copy submissions of required information. Material Safety Data Sheets are also submitted electronically.
The data collected is unique to each formulation and is the minimum necessary to determine potential hazardous effects. A portion of the data collected is proprietary and may not be appropriate for a fully automated collection process. When several similar products are submitted at the same time, submitters may send a single copy of an individual ingredient Material Safety Data Sheet rather than one for each formulation.
Describe efforts to identify duplication. Show specifically why any similar information already available cannot be used or modified for use for the purposes described in Item 2 above.
The Forest Service is unaware of any other information source for this proprietary information. It would not be available through any other source within the Agency, USDA, other government source, or outside of government. Although the MSDSs for the ingredients may be available from the respondent’s supplier, to ensure the FS receives the correct MSDS for the specific ingredient, the Forest Service requires the respondent to provide them.
If the collection of information impacts small businesses or other small entities, describe any methods used to minimize burden.
All potential respondents are from the private sector. Small businesses typically submit a single formulation for evaluation, while large businesses often submit several formulations, and thus responses, at a time. Out of the 7 respondents, 5 are small businesses.
The Agency has worked to reduce the burden for all entities by limiting the collected information to the minimum necessary for Forest Service scientists to make informed decisions on human health and environmental risk; or that necessary to correctly mix and handle the product to provide a fair evaluation.
Describe the consequence to Federal program or policy activities if the collection is not conducted or is conducted less frequently, as well as any technical or legal obstacles to reducing burden.
Without this information, the Forest Service would not be able to assess the safety of wildland fire chemicals used to manage fires on Agency lands because details of product composition are not public information. This would result in the Agency failing to meet Forest Service Manual direction (FSM 5162.02) to utilize, “…fire chemical products to accomplish fire management activities safely, efficiently, and effectively.” [Emphasis added.] The information provided to agency personnel allows them to determine whether formulations contain hazardous ingredients in sufficient quantity to increase the risk to human health or to natural ecosystems to unacceptable levels.
The first safety item that must be addressed by the Agency is whether there are ingredients in the formulation that could be hazardous to the laboratory personnel doing the evaluation. The next concern is the safe use of the product in wildland fire fighting and the potential exposure to the firefighters, the public at large, and to the environment. Knowledge of specific ingredients and their respective quantity in a product allows the Forest Service to make informed decisions regarding the human health and environmental risk of these products.
Explain any special circumstances that would cause an information collection to be conducted in a manner:
Requiring respondents to report information to the agency more often than quarterly;
Information is required once for each formulation, at the time of submission. Only if a respondent wishes to change the formulation would he report information more often than quarterly. We request that the submitter notify us of revisions to the product Material Safety Data Sheet that may occur as part of the regular information review as required by the Occupational Safety and Health Administration, but it is not required.
Requiring respondents to prepare a written response to a collection of information in fewer than 30 days after receipt of it;
Requiring respondents to submit more than an original and two copies of any document;
Requiring respondents to retain records, other than health, medical, government contract, grant-in-aid, or tax records for more than three years;
In connection with a statistical survey, that is not designed to produce valid and reliable results that can be generalized to the universe of study;
Requiring the use of a statistical data classification that has not been reviewed and approved by OMB;
That includes a pledge of confidentiality that is not supported by authority established in statute or regulation, that is not supported by disclosure and data security policies that are consistent with the pledge, or which unnecessarily impedes sharing of data with other agencies for compatible confidential use; or
Requiring respondents to submit proprietary trade secret, or other confidential information unless the agency can demonstrate that it has instituted procedures to protect the information's confidentiality to the extent permitted by law.
There are no other special circumstances. The collection of information is conducted in a manner consistent with the guidelines in 5 CFR 1320.6.
If applicable, provide a copy and identify the date and page number of publication in the Federal Register of the agency's notice, required by 5 CFR 1320.8 (d), soliciting comments on the information collection prior to submission to OMB. Summarize public comments received in response to that notice and describe actions taken by the agency in response to these comments. Specifically address comments received on cost and hour burden.
Describe efforts to consult with persons outside the agency to obtain their views on the availability of data, frequency of collection, the clarity of instructions and record keeping, disclosure, or reporting format (if any), and on the data elements to be recorded, disclosed, or reported.
Consultation with representatives of those from whom information is to be obtained or those who must compile records should occur at least once every 3 years even if the collection of information activity is the same as in prior periods. There may be circumstances that may preclude consultation in a specific situation. These circumstances should be explained.
A Federal Register Notice notifying the public of the 60-day comment period for this information collection renewal was published in Volume 79 page 68209 on November 14, 2014. Two comments were received. Neither was responsive to the information requests. Commenters were referred to the appropriate agency representatives for assistance.
The Forest Service continually seeks comments on specifications and includes the information collection forms in the packages sent electronically to manufacturers expressing an interest in submitting a product for evaluation. Notices are placed in FedBizOps at least every other year requesting additional products and at least every other year requesting comments to assist the Agency to improve the specifications. All comments are reviewed by representatives of the Forest Service and other Federal and state wildland firefighting agencies. The Forest Service consults individually with company representatives who wish to comment on the requirements of the specification or submission procedures, submit a product for evaluation, to obtain clarification of the information requested.
The following businesses (and their listed representatives) have responded to this information collection and were contacted in that regard. Their comments have been collected, as described in the paragraph above and during one-on-one discussion.

There was general agreement among the respondents that most of the information requested is proprietary and therefore not available except through the respondent.
The manufacturer’s Material Safety Data Sheets (MSDSs) may be available elsewhere, but obtaining them from the respondent assures we have correct information.
In general the effort of providing the information requested was considered reasonable, although some respondents required more time than others.
The time required to complete the forms varied depending on the level of experience, complexity of the product, and whether the supplier prepared it or used outside facilities/operators for production. Individual response time varied from 0.5 to 1.75 hours.
Explain any decision to provide any payment or gift to respondents, other than re-enumeration of contractors or grantees.
The FS does not provide payment or gifts to respondents for the information provided.
Describe any assurance of confidentiality provided to respondents and the basis for the assurance in statute, regulation, or agency policy.
The information regarding specific ingredients and quantities of ingredients is proprietary information belonging to the respondent. Information collection occurs after the respondent and the Forest Service have signed a Collection Agreement including confidentiality provisions. The information is kept in a secure location and requests for information are processed under the Freedom of Information Act (FOIA), which exempts such information from disclosure under exemption 4. FOIA exemption 4 covers trade secret information that is privileged or confidential (refers to business information received from outside individuals/businesses).
The proprietary information is not shared with other agencies except as described in US Forest Specifications and when required during consultation with the US Fish and Wildlife Service and NOAA-Fisheries under the National Environmental Protection Act or Endangered Species Act. The information as to whether a product may increase the risk to human health or environmental health is provided from the data the US Forest Service obtains during the product evaluation.
Provide additional justification for any questions of a sensitive nature, such as sexual behavior or attitudes, religious beliefs, and other matters that are commonly considered private. This justification should include the reasons why the agency considers the questions necessary, the specific uses to be made of the information, the explanation to be given to persons from whom the information is requested, and any steps to be taken to obtain their consent.
The information required from the respondents is of a technical nature and relates to composition and performance of a product. It does not include questions of a personal or sensitive nature commonly considered private.
Provide estimates of the hour burden of the collection of information. Indicate the number of respondents, frequency of response, annual hour burden, and an explanation of how the burden was estimated.
• Indicate the number of respondents, frequency of response, annual hour burden, and an explanation of how the burden was estimated. If this request for approval covers more than one form, provide separate hour burden estimates for each form.

The estimate of $38.50/hr. to accomplish the collection activity for the forms assumes a chemist is performing these duties, based upon a review of the development work. The salary was determined by asking a respondent if an annualized salary of approximately $80,000 was appropriate for the individuals preparing the collection forms. The response was that this was a correct approximation, considering the cost to the company per year (including benefit package). The average daily cost was calculated by dividing the annual salary of $80,000 by 261 workdays per year1. The daily cost was divided by 8 (number of hours in an average workday) to determine an hourly cost (increased to the nearest dollar for estimation purposes).
Provide estimates of the total annual cost burden to respondents or record keepers resulting from the collection of information, (do not include the cost of any hour burden shown in items 12 and 14). The cost estimates should be split into two components: (a) a total capital and start-up cost component annualized over its expected useful life; and (b) a total operation and maintenance and purchase of services component.
There are no capital operation and maintenance costs.
Provide estimates of annualized cost to the Federal government. Provide a description of the method used to estimate cost and any other expense that would not have been incurred without this collection of information.
The response to this question covers the actual costs the agency will incur as a result of implementing the information collection. The estimate should cover the entire life cycle of the collection and include costs, if applicable, for:
Employee labor and materials for developing, printing, storing forms
Employee labor and materials for developing computer systems, screens, or reports to support the collection
Employee travel costs
Cost of contractor services or other reimbursements to individuals or organizations assisting in the collection of information
Employee labor and materials for collecting the information
Employee labor and materials for analyzing, evaluating, summarizing, and/or reporting on the collected information

* Taken from: http://www.opm.gov/policy-data-oversight/pay-leave/salaries-wages/2015/general-schedule/, Cost of total benefits as a percentage of total hourly compensation for Federal Government employees was calculated at hourly wage multiplied by 36.25% in accordance with OMB Memorandum M-08 13. Estimated hourly rate and salary costs are rounded to the nearest dollar.
Explain the reasons for any program changes or adjustments reported in items 13 or 14 of OMB form 83-I.
Since multiple similar calculations were not required, all similar requirements were combined during the analysis. As a result, the hours for the Chemist increased and the hours for the Physical Scientist decreased (from .5 to 2hrs. to 15 min. to ½ hour). This resulted in a decrease of 8 responses and 28 hours.
For collections of information whose results are planned to be published, outline plans for tabulation and publication.
There are no plans for the Forest Service to publish the results of this information collection activity.
If seeking approval to not display the expiration date for OMB approval of the information collection, explain the reasons that display would be inappropriate.
The Forest Service requests approval to omit the expiration date for OMB approval from the forms associated with this information collection. The forms are used rarely, are not expected to change, and are collected one time only for each formulation. An expiration date may cause respondents confusion, as they may interpret this as an expiration date for the information provided, which is not the case.
Explain each exception to the certification statement identified in item 19, "Certification Requirement for Paperwork Reduction Act."
The Forest Service is able to certify compliance with all provisions under item 19.
B. Collections of Information Employing Statistical Methods
