FCC Fabric Location Data, Pct Meeting 25/3+ MBPS Dec, 2022

| 0

This layer displays aggregated location based data from the FCC that’s gathered through the Broadband Data Collection program. The number of locations was derived from the number of unique location ids for each block group and aggregated up. Location ids may include multiple units which are not included in our calculations. The number of locations that meet broadband definitions are only for those locations served the required speeds by copper, cable, fiber, or licensed fixed wireless. Satellite, un-licensed fixed wireless, or ‘other’ are not included in our broadband calculations. A location is considered served by wireless alone if it meets the broadband definition (25/3+) by a wireless provider and is not served by any other technology type (not including satellite).

EJ Screen RMP Facility Proximity

| 0

The RMP facility proximity is reflective of the total count of RMP facilities in each block group within 5
km of the average resident in a block group, divided by distance, calculated as the population-weighted
average of blocks in each block group

EJ Screen Hazardous Waste Proximity

| 0

The hazardous waste proximity indicator is reflective of the total count of hazardous waste facilities in
each block group within 5 km of the average resident in a block group, divided by distance, calculated as
the population-weighted average of blocks in each block group. Hazardous waste facilities are defined as
Resource Conservation and Recovery Act (RCRA) handlers that are either operating TSDFs from RCRA or
reporting LQGs from the 2019 BR.

EJ Screen Underground Storage Tanks

| 0

The UST indicator quantifies the relative risk of being affected by a LUST for a block group. The indicator
is derived by the weighted sum of active LUSTs and sum of active and temporarily out of service USTs
within a certain distance from a block group.

EJ Screen PM 2.5

| 0

The PM 2.5 indicator is a measure of potential exposure to inhalable particles that are 2.5 micrometers or smaller. This is measured in terms of annual average concentration in air measured in micrograms per cubic meter. PM 2.5 information included in EJScreen highlights areas across the U.S. that are not meeting the national ambient air quality standard for PM 2.5. In other words, the levels of PM 2.5 present in these areas are deemed harmful to human health. The PM 2.5 indicator in EJScreen is a measure of potential exposure but not a measure of risk. The raw PM 2.5 data is compiled by census tract which is supplied for use in the tool by EPA’s OAQPS. For air toxics risk measures (as opposed to exposure) users can turn to EJScreen’s other three indicators: cancer risk, respiratory HI, and diesel PM.

EJ Screen Ozone

| 0

The ozone indicator in EJScreen reflects potential ozone exposure measured in terms of summer
seasonal daily average maximum concentrations in an 8-hour period measured in parts per billion.

EJ Screen Diesel Particulate Matter

| 0

The Diesel PM indicator is the estimated concentration of Diesel PM as provided by the 2017 Air Toxics
update. The value of the indicator is in µg /m3
, and reported at the Census tract level. Block group level
values are assigned by repeating each parent tract level value.
