Groups who represent producers, distributors, consumers or users, or others that wish to act or continue to act as proponent organizations for the development or maintenance of a Voluntary Product Standard will be required to pay for administrative and technical support services provided by the National Institute of Standards & Technology and such other direct or indirect costs associated with the development or maintenance of that standard as may be deemed appropriate by the Department, including costs to the Department in connection with the operation of the Standard Review Committee and the Standing Committee. Funds may also be provided by a government agency at the request of a proponent organization or when acting on its own behalf for the development or maintenance of a Voluntary Product Standard. Proponents of standards that meet sponsorship criteria established in these procedures shall furnish an initial deposit of funds sufficient to cover the first year's services and other costs. Estimated annual costs will be based on an hourly rate for salary and overhead established by the Department for the National Institute of Standards & Technology's administrative and technical support services plus estimates of direct costs to provide funds for such items as the travel of consumer representatives unable to otherwise attend committee meetings, travel for Department staff, and printing costs. Project funds will be reviewed annually. Excess funds may be refunded or applied to the next accounting period. Should funds from deposits be inadequate during an accounting period, work on the project will continue only if funds are restored to a level estimated adequate to complete the 12-month period.
