RE-Powering America Sites

| 0

Layer displays the locations of contaminated mines, landfills, and industrial sites evaluated by the US Environmental Protection Agency (EPA) for their renewable energy potential. Sample layer shows sites screened for wind-power only.

Electric Substations

| 0

This feature class/shapefile represents electric power substations primarily associated with electric power transmission. In this layer, substations are considered facilities and equipment that switch, transform, or regulate electric power at voltages equal to, or greater than, 69 kilovolts. Substations with … Continued

Emissions & Generation Resource Integrated Database (eGRID)

| 0

This layer displays the locations of the Environmental Protection Agency (EPA) Emissions & Generation Resource Integrated Database (eGRID) sites. The eGRID is a comprehensive source of data on the locations and environmental characteristics of almost all electric power generated in … Continued

Electric Bulk Power Transmission Lines

| 0

This layer represents electric power transmission lines. Transmission Lines are the system of structures, wires, insulators and associated hardware that carry electric energy from one point to another in an electric power system. Lines are operated at relatively high voltages … Continued

Improvements made to service area calculations for all mortality indicators sourced from the California Department of Public Health Death (CDPH) Death Statistical Master File.

| 0

Service area mortality rates now tabulated from ZCTA-level data (instead of county-level data) to provide more accurate small-area estimates. Service area race/ethnicity mortality rates removed. Affected indicators: Cancer Mortality (CA Only); Heart Disease Mortality (CA Only); Stroke Mortality (CA Only); … Continued
