Our regulations, which we put out in draft form and then finalized, laid out a provision for an alternative testing method. The responsibility for the testing method is on the applicant who is wishing to use something that's not provided for in the regulation. It's actually the company that needs to put forward the method that would be appropriate for its equipment. It's to provide flexibility for those that are not following the traditional approach in terms of how they are undertaking their assessments.
