Supporting Statement B

Comprehensive Test Ban Treaty (1 form: 9-4040-A)

OMB Control Number 1028-0059

Collections of Information Employing Statistical Methods

The agency should be prepared to justify its decision not to use statistical methods in any case where such methods might reduce burden or improve accuracy of results. When the question “Does this ICR contain surveys, censuses, or employ statistical methods?” is checked "Yes," the following documentation should be included in Supporting Statement B to the extent that it applies to the methods proposed:

1. Describe (including a numerical estimate) the potential respondent universe and any sampling or other respondent selection method to be used. Data on the number of entities (e.g., establishments, State and local government units, households, or persons) in the universe covered by the collection and in the corresponding sample are to be provided in tabular form for the universe as a whole and for each of the strata in the proposed sample. Indicate expected response rates for the collection as a whole. If the collection had been conducted previously, include the actual response rate achieved during the last collection.

The single canvass in this information collection is conducted as a complete census. The total universe is approximately 2,500 respondents that are business or other for-profit institutions (Table 1 below) and includes all establishments that may have detonated chemical explosions of 300 tons of TNT-equivalent, or greater, at some time during the year.

Table 1. Consolidated estimates of annual burden (private sector)

			PRIVATE SECTOR
	Form No.	Frequency	Number of Respondents	Responses	Completion Time	Burden Hours
1	9-4040-A	Annually	2,500	2,500	15 min	625
T O T A L S			2,500	2,500		625

The expected response rate for this collection will be at least 34%, based on the number of establishments that have traditionally responded to this request for information.

2. Describe the procedures for the collection of information including:

* Statistical methodology for stratification and sample selection,

* Estimation procedure,

* Degree of accuracy needed for the purpose described in the justification,

* Unusual problems requiring specialized sampling procedures, and

* Any use of periodic (less frequent than annual) data collection cycles to reduce burden.

This canvass does not employ sampling techniques. Because the canvass is designed to match specific blasts with specific locations, sampling techniques are not appropriate for this canvass. According to the Comprehensive Test Ban Treaty, because the data must be updated annually, they cannot be collected less frequently. Estimation procedures for non-respondents are described in (3) below.

3. Describe methods to maximize response rates and to deal with issues of non-response. The accuracy and reliability of information collected must be shown to be adequate for intended uses. For collections based on sampling, a special justification must be provided for any collection that will not yield "reliable" data that can be generalized to the universe studied.

Data for small non-respondent operations are assumed to be zero, and data for larger non-respondent operations are imputed from the establishments’ prior reported data for large mine blasts or prior reported data for production.

4. Describe any tests of procedures or methods to be undertaken. Testing is encouraged as an effective means of refining collections of information to minimize burden and improve utility. Tests must be approved if they call for answers to identical questions from 10 or more respondents. A proposed test or set of tests may be submitted for approval separately or in combination with the main collection of information.

The sole customer for this data is the Department of Defense, as is specified in the Memorandum of Agreement. Periodic consultation with this agency is performed to ensure that the data collected are meeting its needs. At present, no formal tests are in progress that would require clearance.

5. Provide the names and telephone numbers of individuals consulted on statistical aspects of the design and the name of the agency unit, contractor(s), grantee(s), or other person(s) who will actually collect and/or analyze the information for the agency.
