EPA is also requiring lead monitoring in large urban areas (Core Based Statistical Areas, or CBSAs, with a population of 500,000 people or more). Monitors will be located along with multi-pollutant ambient monitoring sites (known as the “NCore network”). Lead monitoring at these sites will begin January 1, 2012.
- The NCore network will consist of approximately 80 monitoring sites, of which 63 will be in large urban areas. The requirement to add these monitors replaces an existing requirement to place lead monitors in each CBSA with a population of 500,000 or more people.
