- Applicant's Environmental Report Operating License Renewal Stage 2.6.2 Minority and Low-Income Populations 2.6.2.1 Backqround The NRC performs environmental justice analyses utilizing a 50-mile radius around the plant as the environmental impact site and the state as the geographic area for comparative analysis.
Entergy has adopted this approach for identifying the minority and low-income populations that could be affected by PNPS operations.
Entergy used ArcView geographic information system software to combine U.S. Census Bureau (USCB) TIGER line data with USCB 2000 census data to determine minority and low-income characteristics (at the block-group level) within the 50-mile radius environmental impact site. Entergy included all block groups if any of their area lay within 50 miles of PNPS. The 50-mile radius includes 3,863 block groups. Entergy defines the geographic area for PNPS as a two-state area, with the largest portion of that area (89%) located in Massachusetts and a smaller portion (11%) in Rhode Island.
2.6.2.2 Minority Populations The NRC procedural guidance for performing environmental assessments and considering environmental issues defines a "minority" population as the racial categories: American Indian or Alaskan Native, Asian, Native Hawaiian or Pacific Islander, Black races, other races, more than 2 races, and the aggregate of all minority races.
Hispanic ethnicity is also defined as a minority population category [Reference 2-33]. Hispanic ethnicity is not defined by the USCB as a racial category and, therefore, it is possible to have both white Hispanics and non-white Hispanics (e.g. Black Hispanic, Asian Hispanic). For the purposes of aggregation, a minority population that combines both minority races and Hispanic ethnicity can be defined as all non-white or multiple races plus white Hispanics. As a note, all non-white Hispanics are already counted in the non-white racial minority categories.
NRC guidance indicates that a minority population exists if either of the two following conditions exists:
Exceeds 50 Percent- the minority population of the environmental impact site exceeds 50 percent, or More than 20 PercentagePoints Greater- the minority population percentage of the environmental impact site is significantly greater (typically at least 20 percentage points) than the minority population percentage in the geographic area chosen for comparative analysis.
NRC guidance calls for use of the most recent USCB decennial census data. Entergy used 2000 census data [References 2-43 and 2-44] to determine the percentage of the total population in the two states that belong to each minority category (Table 2-3a). This information
Pilgrim Nuclear Power Station Applicant's Environmental Report Operating License Renewal Stage was then used to calculate minimum thresholds for each minority category. Because no block groups in the 50-mile radius environmental impact site exceeded the 50% minority population criterion above, the "more than 20% greater" criterion was used to establish minority population thresholds (Table 2-3a). Any block group with a minority category percentage that exceeded any of the minimum threshold listed in Table 2-3a was defined as a "minority population."
For each minority category, Entergy divided USCB minority population numbers for each block group by the total population within that block group to obtain the percent of the block group's population that belonged to each minority category. For each of the 3,863 block groups within 50 miles of PNPS, Entergy calculated the percent of the population in each minority category and compared the result to the corresponding geographic area's minority threshold percentages to determine if a minority population exists. The number of block groups that exceeded minority thresholds is summarized in Tables 2-3b and 2-3c. The location of each minority population within 50 miles of PNPS is shown in Figures 2-13 through 2-19 and Figure 2-22.
Based on the "more than 20 percent" criterion, a Native Hawaiian or other Pacific Islander minority population exists in one block group in Suffolk County, Massachusetts. Black minority populations exist in 261 block groups, with 233 of the block groups in Massachusetts and 28 in Rhode Island. Other minority race populations exist in 135 block groups, with 77 occurring in Massachusetts and 58 are in Rhode Island. No block groups exceeded the minimum threshold for more than 2 races. Aggregate of minority racial populations exist in 595 block groups, with 477 of the block groups occurring in Massachusetts and 120 in Rhode Island.
Minority populations based on Hispanic ethnicity occur in 240 block groups, with 145 of them in Massachusetts and 95 in Rhode Island. Minority populations composed of the aggregate of minority races and Hispanic ethnicity populations exist in 651 block groups, with 514 of the block groups occurring in Massachusetts and 137 in Rhode Island. The location of these minority populations is shown in Figure 2-22.
Overall, no minority populations were identified within a 6-mile radius of PNPS. The nearest minority population within a 50-mile radius was in west-central Plymouth County near the community of Brockton where several minority thresholds were exceeded. These populations are approximately 25 miles west of the PNPS site. Other minority populations within 50 miles of PNPS were typically clustered in or near the Boston, Massachusetts and Providence, Rhode Island areas.
2.6.2.3 Low-Income Populations NRC guidance defines "low-income" by using USCB statistical poverty thresholds for the year 1999 [Reference 2-33, Appendix D]. Low-income populations within the 50-mile radius of PNPS were identified using information on both the number of individuals and number of households below the poverty level in Massachusetts and Rhode Island and block groups within the environmental impact site (50-mile radius). The USCB values for the number of individuals and households below the poverty level in Massachusetts was 9.3% and 9.8%, respectively (Table
Pilgrim Nuclear Power Station Applicant's Environmental Report Operating License Renewal Stage 2-3a). The number of individuals and households below the poverty level i6 Rhode Island was 11.9% and 12.4%, respectively.
A low-income population is considered to be present if:,
(1) the low-income population of the block group or environmental impact site exceeds 50%, or (2) the percentage of households below the poverty level in a block group is significantly greater (typically at least 20 points) than the low-income population percentage in the geographic area chosen for comparative analysis.
Because no block groups had more than 50% of its individuals or households below the poverty level, the "greater than 20%" criterion was used to identify low-income populations within the 50-mile radius environmental impact site (Table 2-3a). The number and percentage of block groups that exceeded these thresholds are included in Tables 2-3b and 2-3c. The locations of the low-income populations with the 50-mile radius area are shown in Figures 2-20 and 2-21.
Based on the "more than 20 percent" criterion, low-income "individual" populations exist in 190 block groups in Massachusetts and 79 in Rhode Island. Low-income populations based on the number of "households" exist in 179 block groups in Massachusetts and 74 block groups in Rhode Island.
Overall, no low-income populations were identified within a 6-mile radius of PNPS. The nearest low-income population occurring within a 50-mile radius was in northwest Plymouth County near the community of Brockton where thresholds for both low-income individuals and households were exceeded. These populations are approximately 25 miles northwest of the PNPS site.
Other low-income populations within 50 miles of PNPS were clustered near Boston and in Bristol County near the communities of Fall River and New Bedford, Massachusetts and in Providence County Rhode Island.
