MEMORANDUM

To : Commercial and Institutional Waste Incinerators (CISWI) Rule Docket

From : OAR OAQPS

Subject: Addendum to Docket: “Preliminary Review of the Environmental Justice Impacts for the Following Proposed: Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Commercial and Industrial Solid Waste Incineration (CIS WI) Units; National Emission Standards
for Hazardous Air Pollutants or Area S ources: Industrial, Commercial, and institutional Boilers; National Emission St andards for Hazardous Air Pollutants
for Industrial/Commercial/Inst itutional Boilers and Proce ss Heaters; Identification of Non-hazardous Secondary Material s (NHSM) that are Solid Waste ( April 28, 2010).”

1.0 INTRODUCTION

This addendum transmits the results of the reassessment of the environmental justice (EJ) demographics of t hose populations located in the vi cinity of CISWI units. Based on
data amendments and corrections that were incorporated following public comment on the proposed rule, EPA revised its estimates of the nu mber of units covered by this rule downward from 176 units to 100 units, incl uding incinerators, cement kiln s, and energy recovery units (ERU). As a result of the reduction in the number of units in the source category, it was
determined that a re-evaluation of th e EJ demographics was appropriate.

Executive Order 12898 (59 FR 7629, February 16, 1994) establishes Federal executive policy on EJ. Its main provision directs Federal ag encies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, dispr oportionately high and adverse hum an health or environmental effects of their programs, polic ies, and activities on minority populations and low-income populations in the United States.

In addition to the Executive Order, EPA policy defines “Environmental Justice” to include meaningful involvement of all people regard less of race, color, na tional origin, or income with respect to the development, implementa tion, and enforcement of environmental laws, regulations, and polices 1 . To promote meaningful i nvolvement, EPA has developed a communication and outreach strategy to ensure that interested communities have access to a proposed rule, are aware of its content, and have an opportunity to comment during the comment

1 Whitman, Christine T., Administrator, US Environmental Protection Agency, “EPA’s Commitment to

Environmental Justice.” August 9, 2001period. EPA implemented this st rategy during the comment period for the proposed CISWI rule. EPA publicized the rulemaking via EJ newsletters, Tribal newsletters, EJ listservs, and the internet, including the Office of Polic y’s (OP) Rulemaking Gateway website ( http://yosemite.epa.gov/opei/RuleGate.nsf/ ). EPA also provided general rulemaking fact sheets (e.g., why is this important for my commun ity) for EJ community groups and conducted
conference calls with interested communities. In the final rule, state and federal permitting requirements will provide state and local govern ments and members of affected communities with the opportunity to provide comments on th e permit conditions associated with permitting the sources affected by this rulemaking.

2.0 DEMOGRAPHICS

The following analysis uses a revised data se t of sources coupled with “proximity-to-asource” as a surrogate for exposure to identify those populations considered to be living near affected sources, such that they have notable expo sures to current emissions from these sources. The demographic data for this analysis is censu s block level data extracted from the 2000 census which was provided to the EPA by the US Census Bureau. The socio-demographic parameters used in the analysis included the following cat egories: Racial (White, African American, Native American, Other or Multiracial, All Other Races); Ethnicity (Hispanic); and Other (Number of people below the poverty line, Number of people w ith ages between 0 and 18, Number of people greater than or equal to 65)

As with the original report contained in the docket, this proximity analysis determined the demographic composition of those census blocks w hose centriods lay within a circular distance of 3 miles (approximately 5 km) of the affected sources. This study area ra dius has been used in previous demographic analyses focu sed on areas around industrial sources 2,3 . Also, beyond three
miles the air emissions influence of an individual source is generally considered to be small, both
in absolute terms and relative to the influence of other sources (assuming there are other sources in the area, as is typical in urban areas. The resu lts of the analysis are contained in Table 2.1 (see below):

This EPA analysis revises the demographic data presented in “E xhibit 1 – Populations Within Three-Mile Proximity to Major Source Boilers and CISWI Units” as contained in the report referenced as the subject of this memorandum. When compared to the original demographic analysis, the results of this re-analy sis indicate that the total number of people in proximity to, and potentially impacted by, this source category have declined by approximately
22%. This decrease in the total population has resulted in corresponding changes in the percentage composition of the de mographics in the study areas. The percentage of White and African American both decreased by 2% and 4% re spectively from the previous study, while the percentage of Native Americans, the number of people with ages betw een 0 and age 18, the number of people greater than or equal to age 65, and the number below the poverty level remained relatively unchanged. Other demographic variables, specifically Other or Multiracial, Hispanics, and All Other Races, also decrea sed in total numbers, but their percentage composition in this re-analysis increased by approximately 5%, 2%, and 2% respectively.

When compared to the national averages of these demographics, EPA’s re-analysis shows that the study areas tend to have lower proportions of Whites than the national average (i.e., 69% versus 75%). The proportions of Native Ameri cans (1%), people with ages between 0 and 18 (27%), and those greater than or equal to age 65 (12%) are very cl ose, if not identical, to their respective national averages. However, the prop ortions for the demographic variables African American, Hispanics, Other or Multiracial, the number of people below the poverty line, and All Other Races are higher than their respective nati onal averages with the greatest change occurring in the category Minority (All Non-White). These values compared to their national averages are as follows: African American (13% v. 12% resp ectively) Hispanics (15% v 14% respectively), other or Multiracial (17% v 12% respectively), the number of people below the poverty line (14% v 13% respectively), and All Ot her Races (31% v 25% respectively)Based on the fact that the final rule does not allow emission increases from this source category, EPA has determined that the rule wi ll not have disproportiona tely high and adverse
human health or environmental effe cts on minority or other subpopulatons.
