## I. Abstract

The Clean Air Act (Sections 169A, 169B, and 110(a)(2)(j)) charges the NPS with an “affirmative responsibility to protect air quality related values (including visibility).” The NPS believes the value of visibility changes should be represented in cost-benefit analyses regarding state and Federal efforts that may affect visibility (including the Regional Haze Rule, Title 40, Part 51 of the Code of Federal Regulations). Updated estimates of visibility benefits are required because the studies conducted in the 1970s and 1980s do not reflect current baseline visibility conditions in national parks and wilderness areas.

The NPS plans to conduct a nationwide stated preference survey to estimate the value of visibility changes in national parks and wilderness areas. Survey development and pre-testing have already been conducted under a previous IC (OMB Control Number 1024-0255). The purpose of this IC is to conduct a pilot study to test the survey instrument and implementation procedures prior to the full survey. After the pilot is completed, the NPS will submit a revised IC request to OMB for the full survey.
