Visibility Protection

The Western Regional Air Partnership (WRAP) will provide technical analyses and databases to assist states, tribes, federal land managers, local air agencies and the US EPA with periodic implementation and planning requirements for the Regional Haze Rule in the West.

The effort on Regional Haze includes, but is not limited to:

• Analyses to support air quality planning and management by individual WRAP member jurisdictions and agencies for the Regional Haze Rule;
• Tracking trends, periodic assessments of the nature and causes of Regional Haze, and how the sources and impacts are related to ozone, particulate matter, nitrogen deposition and critical loads, mercury, and other pollutants;
• Emissions sources from all sectors, both domestic and international;
• Effects of air pollution transport; and
• Effects of climate change on regional air quality.

The Landscape of Forever: Visibility Protection in the West is an educational storyboard that provides information about the unique challenges of protecting visibility in western states.

To accomplish these efforts, WRAP develops, maintains, and shares databases, supports technical analyses, and provides access to data and results from various information sources to produce consistent, comparable, and complete results for use by individual WRAP member jurisdictions and agencies.
