· Controlling sediment and erosion problems are critical to an effective storm water pollution prevention plan, or SWPPP. In addition, controlling runoff water helps to reduce erosion and sediment problems and ultimately reduces the environmental impact of a project. Best management for soil and erosion control during construction are outlined in the EPA's SWPPP.

Particle pollution — also called particulate matter (PM) — is made up of particles (tiny pieces) of solids or liquids that are in the air. These particles may include: Some particles are big enough (or appear dark enough) to see — for example, you can often see smoke in the air. Others are so small that you can't see them in the air.
Two regions of California experience some of the highest air pollution levels in the entire United States: the San Joaquin Valley and South Coast Air Basins. Accelerating progress on this public health challenge requires an allout team effort – while also maintaining sensitivity to each region's unique demographic and air quality profiles.
